Bazaar Release Notes
--------------------
.. contents::
IN DEVELOPMENT
--------------
IMPROVEMENTS:
* Progress bars now show the rate of activity for some sftp
operations, and they are drawn different. (Martin Pool, #172741)
* Progress bars now show the rate of activity for some^H *all* hhtp ;)
operations for both urllib and pycurl implementations.
(Vincent Ladeuil)
BUG FIXES:
* There was a bug in how we handled resolving when a file is deleted
in one branch, and modified in the other. If there was a criss-cross
merge, we would cause the deletion to conflict a second time.
(Vincent Ladeuil, John Arbash Meinel)
NOT RELEASED YET
----------------
COMPATIBILITY BREAKS:
* By default, ``bzr status`` after a merge now shows just the pending
merge tip revisions. This improves the signal-to-noise ratio after
merging from trunk and completes much faster. To see all merged
revisions, use the new ``-v`` flag. (Ian Clatworthy)
* ``bzr log --line`` now shows any tags after the date and before
the commit message. If you have scripts which parse the output
from this command, you may need to adjust them accordingly.
(Ian Clatworthy)
NEW FEATURES:
IMPROVEMENTS:
* ``bzr init`` will now print a little less verbose output.
(Marius Kruger)
* ``bzr log --short`` and ``bzr log --line`` now show tags, if any,
for each revision. The tags are shown comma-separated inside
``{}``. For short format, the tags appear at the end of line
before the optional ``[merge]`` indicator. For line format,
the tags appear after the date. (Ian Clatworthy)
* Rule-based preferences can now accept multiple patterns for a set of
rules. (Marius Kruger)
BUG FIXES:
* ``bzr log FILE`` now correctly shows mainline revisions merging
a change to FILE when the ``--short`` and ``--line`` log formats
are used. (Ian Clatworthy, #317417)
* Don't require the present compression base in knits to be the same
when adding records in knits. (Jelmer Vernooij, #307394)
* Fix a problem with CIFS client/server lag on Windows colliding with
an invariant-per-process algorithm for generating AtomicFile names
(Adrian Wilkins, #304023)
* Many socket operations now handle EINTR by retrying the operation.
Previously EINTR was treated as an unrecoverable failure. There is
a new ``until_no_eintr`` helper function in ``bzrlib.osutils``.
(Andrew Bennetts)
DOCUMENTATION:
API CHANGES:
* ``ProgressBarStack`` is deprecated; instead use
``ui_factory.nested_progress_bar`` to create new progress bars.
TESTING:
INTERNALS:
* Default User Interface (UI) is CLIUIFactory when bzr runs in a dumb
terminal. It is sometimes desirable do override this default by forcing
bzr to use TextUIFactory. This can be achieved by setting the
BZR_USE_TEXT_UI environment variable (emacs shells, as opposed to
compile buffers, are such an example).
(Vincent Ladeuil)
* New API ``Branch.iter_merge_sorted_revisions()`` that iterates over
``(revision_id, depth, revno, end_of_merge)`` tuples.
(Ian Clatworthy)
* New ``Branch.dotted_revno_to_revision_id()`` and
``Branch.revision_id_to_dotted_revno()`` APIs that pick the most
efficient way of doing the mapping.
(Ian Clatworthy)
* ``TreeDelta.show()`` now accepts a ``filter`` parameter allowing log
formatters to retrict the output.
(Vincent Ladeuil)
bzr 1.11rc1 "Eyes up!" 2009-01-09
---------------------------------
This first monthly release of Bazaar for 2009 improves Bazaar's operation
in Windows, Mac OS X, and other situations where file names are matched
without regard to capitalization: Bazaar tries to match the case of an
existing file. This release of Bazaar also improves the efficiency of
Tortoise Windows Shell integration and lets it work on 64-bit platforms.
The UI through which Bazaar supports historic formats has been improved,
so 'bzr help formats' now gives a simpler and shorter list, with clear
advice.
This release also fixes a number of bugs, particularly a glitch that can
occur when there are concurrent writes to a pack repository.
CHANGES:
* Formats using Knit-based repository formats are now explicitly
marked as deprecated. (Ian Clatworthy)
NEW FEATURES:
* Add support for `bzr tags -r 1..2`, that is we now support showing
tags applicable for a specified revision range. (Marius Kruger)
* ``authentication.conf`` now accepts pluggable read-only credential
stores. Such a plugin (``netrc_credential_store``) is now included,
handles the ``$HOME/.netrc`` file and can server as an example to
implement other plugins.
(Vincent Ladeuil)
* ``shelve --list`` can now be used to list shelved changes.
(Aaron Bentley)
IMPROVEMENTS:
* Add trailing slash to directories in all output of ``bzr ls``, except
``bzr ls --null``. (Gordon P. Hemsley, #306424)
* ``bzr revision-info`` now supports a -d option to specify an
alternative branch. (Michael Hudson)
* Add connection to a C++ implementation of the Windows Shell Extension
which is able to fully replace the current Python implemented one.
Advantages include 64bit support and reduction in overhead for
processes which drag in shell extensions.
(Mark Hammond)
* Support the Claws mail client directly, rather than via
xdg-email. This prevents the display of an unnecessary modal
dialog in Claws, informing the user that a file has been
attached to the message, and works around bug #291847 in
xdg-utils which corrupts the destination address.
* When working on a case-insensitive case-preserving file-system, as
commonly found with Windows, bzr will often ignore the case of the
arguments specified by the user in preference to the case of an existing
item on the file-system or in the inventory to help prevent
counter-intuitive behaviour on Windows. (Mark Hammond)
BUG FIXES:
* Allow BzrDir implementation to implement backing up of
control directory. (#139691)
* ``bzr push`` creating a new stacked branch will now only open a
single connection to the target machine. (John Arbash Meinel)
* Don't call iteritems on transport_list_registry, because it may
change during iteration. (Martin Pool, #277048)
* Don't make a broken branch when pushing an unstackable-format branch
that's in a stackable shared repository to a location with default
stack-on location. (Andrew Bennetts, #291046)
* Don't require embedding user in HTTP(S) URLs do use authentication.conf.
(Ben Jansen, Vincent Ladeuil, #300347)
* Fix a problem with CIFS client/server lag on windows colliding with
an invariant-per-process algorithm for generating AtomicFile names
(Adrian Wilkins, #304023)
* Fix bogus setUp signature in UnavailableFTPServer.
(Gary van der Merwe, #313498)
* Fix compilation error in ``_dirstate_helpers_c`` on SunOS/Solaris.
(Jari Aalto)
* Fix SystemError in ``_patiencediff_c`` module by calling
PyErr_NoMemory() before returning NULL in PatienceSequenceMatcher_new.
(Andrew Bennetts, #303206)
* Give proper error message for diff with non-existent dotted revno.
(Marius Kruger, #301969)
* Handle EACCES (permission denied) errors when launching a message
editor, and emit warnings when a configured editor cannot be
started. (Andrew Bennetts)
* ``$HOME/.netrc`` file is now recognized as a read-only credential store
if configured in ``authentication.conf`` with 'password_encoding=netrc'
in the appropriate sections.
(Vincent Ladeuil, #103029)
* Opening a stacked branch now properly shares the connection, rather
than opening a new connection for the stacked-on branch.
(John Arbash meinel)
* Preserve transport decorators while following redirections.
(Vincent Ladeuil, #245964, #270863)
* Provides a finer and more robust filter for accepted redirections.
(Vincent Ladeuil, #303959, #265070)
* ``shelve`` paths are now interpreted relative to the current working
tree. (Aaron Bentley)
* ``Transport.readv()`` defaults to not reading more than 100MB in a
single array. Further ``RemoteTransport.readv`` sets this to 5MB to
work better with how it splits its requests.
(John Arbash Meinel, #303538)
* Pack repositories are now able to reload the pack listing and retry
the current operation if another action causes the data to be
repacked. (John Arbash Meinel, #153786)
* ``pull -v`` now respects the log_format configuration variable.
(Aaron Bentley)
* ``push -v`` now works on non-initial pushes. (Aaron Bentley)
* Use the short status format when the short format is used for log.
(Vincent Ladeuil, #87179)
* Allow files to be renamed or moved via remove + add-by-id. (Charles
Duffy, #314251)
DOCUMENTATION:
* Improved the formats help topic to explain why multiple formats
exist and to provide guidelines in selecting one. Introduced
two new supporting help topics: current-formats and other-formats.
(Ian Clatworthy)
API CHANGES:
* ``LRUCache(after_cleanup_size)`` was renamed to
``after_cleanup_count`` and the old name deprecated. The new name is
used for clarity, and to avoid confusion with
``LRUSizeCache(after_cleanup_size)``. (John Arbash Meinel)
* New ``ForeignRepository`` base class, to help with foreign branch
support (e.g. svn). (Jelmer Vernooij)
* ``node_distances`` and ``select_farthest`` can no longer be imported
from ``bzrlib.graph``. They can still be imported from
``bzrlib.deprecated_graph``, which has been the preferred way to
import them since before 1.0. (Andrew Bennetts)
* The logic in commit now delegates inventory basis calculations to
the ``CommitBuilder`` object; this requires that the commit builder
in use has been updated to support the new ``recording_deletes`` and
``record_delete`` methods. (Robert Collins)
TESTING:
* An HTTPS server is now available (it requires python-2.6). Future bzr
versions will allow the use of the python-2.6 ssl module that can be
installed for 2.5 and 2.4.
* ``bzr selftest`` now fails if new trailing white space is added to
the bazaar sources. It only checks changes not committed yet. This
means that PQM will now reject changes that introduce new trailing
whitespace. (Marius Kruger)
* Introduced new experimental formats called ``1.12-preview`` and
``1.12-preview-rich-root`` to enable testing of related pending
features, namely content filtering and filtered views.
(Ian Clatworthy)
INTERNALS:
* Added an ``InventoryEntry`` cache when deserializing inventories.
Can cut the time to iterate over multiple RevisionsTrees in half.
(John Arbash Meinel)
* Added ``bzrlib.fifo_cache.FIFOCache`` which is designed to have
minimal overhead versus using a plain dict for cache hits, at the
cost of not preserving the 'active' set as well as an ``LRUCache``.
(John Arbash Meinel)
* ``bzrlib.patience_diff.unified_diff`` now properly uses a tab
character to separate the filename from the date stamp, and doesn't
add trailing whitespace when a date stamp is not supplied.
(Adeodato Simó, John Arbash Meinel)
* ``DirStateWorkingTree`` and ``DirStateWorkingTreeFormat`` added
as base classes of ``WorkingTree4`` and ``WorkingTreeFormat4``
respectively. (Ian Clatworthy)
* ``KnitVersionedFiles._check_should_delta()`` now uses the
``get_build_details`` api to avoid multiple hits to the index, and
to properly follow the ``compression_parent`` rather than assuming
it is the left-hand parent. (John Arbash Meinel)
* ``KnitVersionedFiles.get_record_stream()`` will now chose a
more optimal ordering when the keys are requested 'unordered'.
Previously the order was fully random, now the records should be
returned from each pack in turn, in forward I/O order.
(John Arbash Meinel)
* ``mutter()`` will now flush the ``~/.bzr.log`` if it has been more
than 2s since the last time it flushed. (John Arbash Meinel)
* New method ``bzrlib.repository.Repository.add_inventory_by_delta``
allows adding an inventory via an inventory delta, which can be
more efficient for some repository types. (Robert Collins)
* Repository ``CommitBuilder`` objects can now accumulate an inventory
delta. To enable this functionality call ``builder.recording_deletes``
and additionally call ``builder.record_delete`` when a delete
against the basis occurs. (Robert Collins)
* The default http handler has been changed from pycurl to urllib.
The default is still pycurl for https connections. (The only
advantage of pycurl is that it checks ssl certificates.)
(John Arbash Meinel)
* The progress and UI classes have changed; the main APIs remain the
same but code that provides a new UI or progress bar class may
need to be updated. (Martin Pool)
* ``VersionedFiles.get_record_stream()`` can now return objects with a
storage_kind of ``chunked``. This is a collection (list/tuple) of
strings. You can use ``osutils.chunks_to_lines()`` to turn them into
guaranteed 'lines' or you can use ``''.join(chunks)`` to turn it
into a fulltext. This allows for some very good memory savings when
asking for many texts that share ancestry, as the individual chunks
can be shared between versions of the file. (John Arbash Meinel)
* ``pull -v`` and ``push -v`` use new function
``bzrlib.log.show_branch_change`` (Aaron Bentley)
bzr 1.10 2008-12-05
-------------------
Bazaar 1.10 has several performance improvements for copying revisions
(especially for small updates to large projects). There has also been a
significant amount of effort in polishing stacked branches. The commands
``shelve`` and ``unshelve`` have become core commands, with an improved
implementation.
The only changes versus bzr-1.10rc1 are bugfixes for stacked branches.
BUG FIXES:
* Don't set a pack write cache size from RepoFetcher, because the
cache is not coherent with reads and causes ShortReadvErrors.
This reverses the change that fixed #294479.
(Martin Pool, #303856)
* Properly handle when a revision can be inserted as a delta versus
when it needs to be expanded to a fulltext for stacked branches.
There was a bug involving merge revisions. As a method to help
prevent future difficulties, also make stacked fetches sort
topologically. (John Arbash Meinel, #304841)
bzr 1.10rc1 2008-11-28
----------------------
This release of Bazaar focuses on performance improvements when pushing
and pulling revisions, both locally and to remote networks. The popular
``shelve`` and ``unshelve`` commands, used to interactively revert and
restore work in progress, have been merged from bzrtools into the bzr
core. There are also bug fixes for portability, and for stacked branches.
NEW FEATURES:
* New ``commit_message_template`` hook that is called by the commit
code to generate a template commit message. (Jelmer Vernooij)
* New `shelve` and `unshelve` commands allow undoing and redoing changes.
(Aaron Bentley)
IMPROVEMENTS:
* ``(Remote)Branch.copy_content_into`` no longer generates the full revision
history just to set the last revision info.
(Andrew Bennetts, John Arbash Meinel)
* Fetches between formats with different serializers (such as
pack-0.92-subtree and 1.9-rich-root) are faster now. This is due to
operating on batches of 100 revisions at time rather than
one-by-one. (Andrew Bennetts, John Arbash Meinel)
* Search index files corresponding to pack files we've already used
before searching others, because they are more likely to have the
keys we're looking for. This reduces the number of iix and tix
files accessed when pushing 1 new revision, for instance.
(John Arbash Meinel)
* Signatures to transfer are calculated more efficiently in
``item_keys_introduced_by``. (Andrew Bennetts, John Arbash Meinel)
* The generic fetch code can once again copy revisions and signatures
without extracting them completely to fulltexts and then serializing
them back down into byte strings. This is a significant performance
improvement when fetching from a stacked branch.
(John Arbash Meinel, #300289)
* When making a large readv() request over ``bzr+ssh``, break up the
request into more manageable chunks. Because the RPC is not yet able
to stream, this helps keep us from buffering too much information at
once. (John Arbash Meinel)
BUG FIXES:
* Better message when the user needs to set their Launchpad ID.
(Martin Pool, #289148)
* ``bzr commit --local`` doesn't access the master branch anymore.
This fixes a regression introduced in 1.9. (Marius Kruger, #299313)
* Don't call the system ``chdir()`` with an empty path. Sun OS seems
to give an error in that case. Also, don't count on ``getcwd()``
being able to allocate a new buffer, which is a gnu extension.
(John Arbash Meinel, Martin Pool, Harry Hirsch, #297831)
* Don't crash when requesting log --forward <file> for a revision range
starting with a dotted revno.
(Vincent Ladeuil, #300055)
* Don't create text deltas spanning stacked repositories; this could
cause "Revision X not present in Y" when later accessing them.
(Martin Pool, #288751)
* Pack repositories are now able to reload the pack listing and retry
the current operation if another action causes the data to be
repacked. (John Arbash Meinel, #153786)
* PermissionDenied errors from smart servers no longer cause
"PermissionDenied: "None"" on the client.
(Andrew Bennetts, #299254)
* Pushing to a stacked pack repository now batches writes, the same
way writes are batched to ordinary pack repository. This makes
pushing to a stacked branch over the network much faster.
(Andrew Bennetts, #294479)
* TooManyConcurrentRequests no longer occur when a fetch fails and
tries to abort a write group. This allows the root cause (e.g. a
network interruption) to be reported. (Andrew Bennetts, #297014)
* RemoteRepository.get_parent_map now uses fallback repositories.
(Aaron Bentley, #297991?, #293679?)
API CHANGES:
* ``CommitBuilder`` now validates the strings it will be committing,
to ensure that they do not have characters that will not be properly
round-tripped. For now, it just checks for characters that are
invalid in the XML form. (John Arbash Meinel, #295161)
* Constructor parameters for NewPack (internal to pack repositories)
have changed incompatibly.
* ``Repository.abort_write_group`` now accepts an optional
``suppress_errors`` flag. Repository implementations that override
``abort_write_group`` will need to be updated to accept the new
argument. Subclasses that only override ``_abort_write_group``
don't need to change.
* Transport implementations must provide copy_tree_to_transport. A default
implementation is provided for Transport subclasses.
TESTING:
* ``bzr selftest`` now fails if no doctests are found in a module
that's expected to have them. (Martin Pool)
* Doctests now only report the first failure. (Martin Pool)
bzr 1.9 2008-11-07
------------------
This release of Bazaar adds a new repository format, ``1.9``, with smaller
and more efficient index files. This format can be specified when
creating a new repository, or used to losslessly upgrade an existing
repository. bzr 1.9 also speeds most operations over the smart server
protocol, makes annotate faster, and uses less memory when making
checkouts or pulling large amounts of data.
BUG FIXES:
* Fix "invalid property value 'branch-nick' for None" regression with
branches bound to svn branches. (Martin Pool, #293440)
* Fix SSL/https on Python2.6. (Vincent Ladeuil, #293054)
* ``SFTPTransport.readv()`` had a bug when requests were out-of-order.
This only triggers some-of-the-time on Knit format repositories.
(John Arbash Meinel, #293746)
bzr 1.9rc1 2008-10-31
---------------------
NEW FEATURES:
* New Branch hook ``transform_fallback_location`` allows a function to
be called when looking up the stacked source. (Michael Hudson)
* New repository formats ``1.9`` and ``1.9-rich-root``. These have all
the functionality of ``1.6``, but use the new btree indexes.
These indexes are both smaller and faster for access to historical
information. (John Arbash Meinel)
IMPROVEMENTS:
* ``BTreeIndex`` code now is able to prefetch extra pages to help tune
the tradeoff between bandwidth and latency. Should be tuned
appropriately to not impact commands which need minimal information,
but provide a significant boost to ones that need more context. Only
has a direct impact on the ``--development2`` format which uses
btree's for the indexes. (John Arbash Meinel)
* ``bzr dump-btree`` is a hidden command introduced to allow dumping
the contents of a compressed btree file. (John Arbash Meinel)
* ``bzr pack`` now tells the index builders to optimize for size. For
btree index repositories, this can save 25% of the index size
(mostly in the text indexes). (John Arbash Meinel)
* ``bzr push`` to an existing branch or repository on a smart server
is faster, due to Bazaar making more use of the ``get_parent_map``
RPC when querying the remote branch's revision graph.
(Andrew Bennetts)
* default username for bzr+ssh and sftp can be configured in
authentication.conf. (Aaron Bentley)
* launchpad-login now provides a default username for bzr+ssh and sftp
URLs, allowing username-free URLs to work for everyone. (Aaron Bentley)
* ``lp:`` lookups no longer include usernames, making them shareable and
shorter. (Aaron Bentley)
* New ``PackRepository.autopack`` smart server RPC, which does
autopacking entirely on the server. This is much faster than
autopacking via plain file methods, which downloads a large amount
of pack data and then re-uploads the same pack data into a single
file. This fixes a major (although infrequent) cause of lengthy
delays when using a smart server. For example, pushing the 10th
revision to a repository with 9 packs now takes 44 RPCs rather than
179, and much less bandwidth too. This requires Bazaar 1.9 on both
the client and the server, otherwise the client will fallback to the
slower method. (Andrew Bennetts)
BUG FIXES:
* A failure to load a plugin due to an IncompatibleAPI exception is
now correctly reported. (Robert Collins, #279451)
* API versioning support now has a multiple-version checking api
``require_any_api``. (Robert Collins, #279447)
* ``bzr branch --stacked`` from a smart server to a standalone branch
works again. This fixes a regression in 1.7 and 1.8.
(Andrew Bennetts, #270397)
* ``bzr co`` uses less memory. It used to unpack the entire WT into
memory before writing it to disk. This was a little bit faster, but
consumed lots of memory. (John Arbash Meinel, #269456)
* ``bzr missing --quiet`` no longer prints messages about whether
there are missing revisions. The exit code indicates whether there
were or not. (Martin Pool, #284748)
* Fixes to the ``annotate`` code. The fast-path which re-used the
stored deltas was accidentally disabled all the time, instead of
only when a branch was stacked. Second, the code would accidentally
re-use a delta even if it wasn't against the left-parent, this
could only happen if ``bzr reconcile`` decided that the parent
ordering was incorrect in the file graph. (John Arbash Meinel)
* "Permission denied" errors that occur when pushing a new branch to a
smart server no longer cause tracebacks. (Andrew Bennetts, #278673)
* Some compatibility fixes for building the extensions with MSVC and
for python2.4. (John Arbash Meinel, #277484)
* The index logic is now able to reload the list of pack files if and
index ends up disappearing. We still don't reload if the pack data
itself goes missing after checking the index. This bug appears as a
transient failure (file not found) when another process is writing
to the repository. (John Arbash Meinel, #153786)
* ``bzr switch`` and ``bzr bind`` will now update the branch nickname if
it was previously set. All checkouts will now refer to the bound branch
for a nickname if one was not explicitly set.
(Marius Kruger, #230903)
DOCUMENTATION:
* Improved hook documentation. (Michael Ernst)
API CHANGES:
* commands.plugins_cmds is now a CommandRegistry, not a dict.
INTERNALS:
* New AuthenticationConfig.set_credentials method allows easy programmatic
configuration of authetication credentials.
bzr 1.8 2008-10-16
------------------
Bazaar 1.8 includes several fixes that improve working tree performance,
display of revision logs, and merges. The bzr testsuite now passes on OS
X and Python 2.6, and almost completely passes on Windows. The
smartserver code has gained several bug fixes and performance
improvements, and can now run server-side hooks within an http server.
BUG FIXES:
* Fix "Must end write group" error when another error occurs during
``bzr push``. (Andrew Bennetts, #230902)
PORTABILITY:
* Some Pyrex versions require the WIN32 macro defined to compile on
that platform. (Alexander Belchenko, Martin Pool, #277481)
bzr 1.8rc1 2008-10-07
---------------------
CHANGES:
* ``bzr log file`` has been changed. It now uses a different method
for determining which revisions to show as merging the changes to
the file. It now only shows revisions which merged the change
towards your mainline. This simplifies the output, makes it faster,
and reduces memory consumption. (John Arbash Meinel)
* ``bzr merge`` now defaults to having ``--reprocess`` set, whenever
``--show-base`` is not supplied. (John Arbash Meinel)
* ``bzr+http//`` will now optionally load plugins and write logs on the
server. (Marius Kruger)
* ``bzrlib._dirstate_helpers_c.pyx`` does not compile correctly with
Pyrex 0.9.4.1 (it generates C code which causes segfaults). We
explicitly blacklist that version of the compiler for that
extension. Packaged versions will include .c files created with
pyrex >= 0.9.6 so it doesn't effect releases, only users running
from the source tree. (John Arbash Meinel, #276868)
FEATURES:
* bzr is now compatible with python-2.6. python-2.6 is not yet officially
supported (nor released, tests were conducted with the dev version of
python-2.6rc2), but all known problems have been fixed. Feedback
welcome.
(Vincent Ladeuil, #269535)
IMPROVEMENTS:
* ``bzr annotate`` will now include uncommitted changes from the local
working tree by default. Such uncommitted changes are given the
revision number they would get if a commit was done, followed with a
? to indicate that its not actually known. (Robert Collins, #3439)
* ``bzr branch`` now accepts a ``--standalone`` option, which creates a
standalone branch regardless of the presence of shared repositories.
(Daniel Watkins)
* ``bzr push`` is faster in the case there are no new revisions to
push. It is also faster if there are no tags in the local branch.
(Andrew Bennetts)
* File changes during a commit will update the tree stat cache.
(Robert Collins)
* Location aliases can now accept a trailing path. (Micheal Hudson)
* New hooks ``Lock.hooks`` when LockDirs are acquired and released.
(Robert Collins, MartinPool)
* Switching in heavyweight checkouts uses the master branch's context, not
the checkout's context. (Adrian Wilkins)
* ``status`` on large trees is now faster, due to optimisations in the
walkdirs code. Of particular note, the walkdirs code now performs
a temporary ``chdir()`` while reading a single directory; if your
platform has non thread-local current working directories (and is
not windows which has its own implementation), this may introduce a
race condition during concurrent uses of bzrlib. The bzrlib CLI
will not encounter this as it is single threaded for working tree
operations. (Robert Collins)
* The C extensions now build on python 2.4 (Robert Collins, #271939)
* The ``-Dhpss`` debug flag now reports the number of smart server
calls per medium to stderr. This is in addition to the existing
detailed logging to the .bzr.log trace file. (Andrew Bennetts)
BUG FIXES:
* Avoid random failures arising from misinterpreted ``errno`` values
in ``_readdir_pyx.read_dir``.
(Martin Pool, #279381)
* Branching from a shared repository on a smart server into a new
repository now preserves the repository format.
(Andrew Bennetts, #269214)
* ``bzr log`` now accepts a ``--change`` option.
(Vincent Ladeuil, #248427)
* ``bzr missing`` now accepts an ``--include-merges`` option.
(Vincent Ladeuil, #233817)
* Don't try to filter (internally) '.bzr' from the files to be deleted if
it's not there.
(Vincent Ladeuil, #272648)
* Fix '_in_buffer' AttributeError when using the -Dhpss debug flag.
(Andrew Bennetts)
* Fix TooManyConcurrentRequests errors caused by a connection failure
when doing ``bzr pull`` or ``bzr merge`` from a ``bzr+ssh`` URL.
(Andrew Bennetts, #246233)
* Fixed ``bzr st -r branch:PATH_TO_BRANCH`` where the other branch
is in a different repository than the current one.
(Lukáš Lalinský, #144421)
* Make the first line of the manpage preamble a comment again.
(David Futcher, #242106)
* Remove use of optional parameter in GSSAPI FTP support, since
it breaks newer versions of Python-Kerberos. (Jelmer Vernooij)
* The autopacking logic will now always create a single new pack from
all of the content which it deems is worth moving. This avoids the
'repack a single pack' bug and should result in better packing
overall. (John Arbash Meinel, #242510, #172644)
* Trivial documentation fix.
(John Arbash Meinel, #270471)
* ``bzr switch`` and ``bzr bind`` will now update the branch nickname if
it was previously set. All checkouts will now refer to the bound branch
for a nickname if one was not explicitly set.
(Marius Kruger, #230903)
DOCUMENTATION:
* Explain revision/range identifiers. (Daniel Clemente)
API CHANGES:
* ``CommitBuilder.record_entry_contents`` returns one more element in
its result tuple - an optional file system hash for the hash cache
to use. (Robert Collins)
* ``dirstate.DirState.update_entry`` will now only calculate the sha1
of a file if it is likely to be needed in determining the output
of iter_changes. (Robert Collins)
* The PackRepository, RepositoryPackCollection, NewPack classes have a
slightly changed interface to support different index types; as a
result other users of these classes need to supply the index types
they want. (Robert Collins)
TESTING:
* ``bzrlib.tests.repository_implementations`` has been renamed to
``bzrlib.tests.per_repository`` so that we have a common structure
(and it is shorter). (John Arbash Meinel, #239343)
* ``LocalTransport.abspath()`` now returns a drive letter if the
transport has one, fixing numerous tests on Windows.
(Mark Hammond)
* PreviewTree is now tested via intertree_implementations.
(Aaron Bentley)
* The full test suite is passing again on OSX.
(Guillermo Gonzalez, Vincent Ladeuil)
* The full test suite passes when run with ``-Eallow_debug``.
(Andrew Bennetts)
INTERNALS:
* A new hook, ``Branch.open``, has been added, which is called when
branch objects are opened. (Robert Collins)
* ``bzrlib.osutils._walkdirs_utf8`` has been refactored into common
tree walking, and modular directory listing code to aid future
performance optimisations and refactoring. (Robert Collins)
* ``bzrlib.trace.debug_memory`` can be used to get a quick memory dump
in the middle of processing. It only reports memory if
``/proc/PID/status`` is available. (John Arbash Meinel)
* New method ``RevisionSpec.as_tree`` for representing the revision
specifier as a revision tree object. (Lukáš Lalinský)
* New race-free method on MutableTree ``get_file_with_stat`` for use
when generating stat cache results. (Robert Collins)
* New win32utils.get_local_appdata_location() provides access to a local
directory for storing data. (Mark Hammond)
* To be compatible with python-2.6 a few new rules should be
observed. 'message' attribute can't be used anymore in exception
classes, 'sha' and 'md5' modules have been deprecated (use
osutils.[md5|sha]), object__init__ and object.__new__ don't accept
parameters anymore.
(Vincent Ladeuil)
bzr 1.7.1 2008-10-01
--------------------
No changes from 1.7.1rc1.
bzr 1.7.1rc1 2008-09-24
-----------------------
This release just includes an update to how the merge algorithm handles
file paths when we encounter complex history.
FEATURES:
* If we encounter a criss-cross in history, use information from
direct Least Common Ancestors to resolve inventory shape (locations
of files, adds, deletes, etc). This is similar in concept to using
``--lca`` for merging file texts, only applied to paths.
(John Arbash Meinel)
bzr 1.7 2008-09-23
------------------
This release includes many bug fixes and a few performance and feature
improvements. ``bzr rm`` will now scan for missing files and remove them,
like how ``bzr add`` scans for unknown files and adds them. A bit more
polish has been applied to the stacking code. The b-tree indexing code has
been brought in, with an eye on using it in a future repository format.
There are only minor installer changes since bzr-1.7rc2.
FEATURES
* Some small updates to the win32 installer. Include localization
files found in plugins, and include the builtin distutils as part of
packaging qbzr. (Mark Hammond)
bzr 1.7rc2 2008-09-17
---------------------
A few bug fixes from 1.7rc1. The biggest change is a new
``RemoteBranch.get_stacked_on_url`` rpc. This allows clients that are
trying to access a Stacked branch over the smart protocol, to properly
connect to the stacked-on location.
BUG FIXES:
* Branching from a shared repository on a smart server into a new
repository now preserves the repository format.
(Andrew Bennetts, #269214)
* Branching from a stacked branch via ``bzr+ssh`` can properly connect
to the stacked-on branch. (Martin Pool, #261315)
* ``bzr init`` no longer re-opens the BzrDir multiple times.
(Vincent Ladeuil)
* Fix '_in_buffer' AttributeError when using the -Dhpss debug flag.
(Andrew Bennetts)
bzr 1.7rc1 2008-09-09
---------------------
This release candidate for bzr 1.7 has several bug fixes and a few
performance and feature improvements. ``bzr rm`` will now scan for
missing files and remove them, like how ``bzr add`` scans for unknown
files and adds them. A bit more polish has been applied to the stacking
code. The b-tree indexing code has been brought in, with an eye on using
it in a future repository format.
CHANGES:
* ``bzr export`` can now export a subdirectory of a project.
(Robert Collins)
* ``bzr remove-tree`` will now refuse to remove a tree with uncommitted
changes, unless the ``--force`` option is specified.
(Lukáš Lalinský, #74101)
* ``bzr rm`` will now scan for files that are missing and remove just
them automatically, much as ``bzr add`` scans for new files that
are not ignored and adds them automatically. (Robert Collins)
FEATURES
* Support for GSSAPI authentication when using FTP as documented in
RFC2228. (Jelmer Vernooij, #49623)
* Add support for IPv6 in the smart server. (Jelmer Vernooij, #165014)
IMPROVEMENTS:
* A url like ``log+file:///tmp`` will log all access to that Transport
to ``.bzr.log``, which may help in debugging or profiling.
(Martin Pool)
* ``bzr branch`` and ``bzr push`` use the default stacking policy if the
branch format supports it. (Aaron Bentley)
* ``bzr init`` and ``bzr init-repo`` will now print out the same as
``bzr info`` if it completed successfully.
(Marius Kruger)
* ``bzr uncommit`` logs the old tip revision id, and displays how to
restore the branch to that tip using ``bzr pull``. This allows you
to recover if you realize you uncommitted the wrong thing.
(John Arbash Meinel)
* Fix problems in accessing stacked repositories over ``bzr://``.
(Martin Pool, #261315)
* ``SFTPTransport.readv()`` was accidentally using ``list += string``,
which 'works', but adds each character separately to the list,
rather than using ``list.append(string)``. Fixing this makes the
SFTP transport a little bit faster (~20%) and use a bit less memory.
(John Arbash Meinel)
* When reading index files, if we happen to read the whole file in a
single request treat it as a ``_buffer_all`` request. This happens
most often on small indexes over remote transports, where we default
to reading 64kB. It saves a round trip for each small index during
fetch operations. Also, if we have read more than 50% of an index
file, trigger a ``_buffer_all`` on the next request. This works
around some inefficiencies because reads don't fall neatly on page
boundaries, so we would ignore those bytes, but request them again
later. This could trigger a total read size of more than the whole
file. (John Arbash Meinel)
BUG FIXES:
* ``bzr rm`` is now aliased to ``bzr del`` for the convenience of svn
users. (Robert Collins, #205416)
* Catch the infamous "select/poll returned error" which occurs when
pycurl try to send a body request to an HTTP/1.0 server which has
already refused to handle the request. (Vincent Ladeuil, #225020)
* Fix ``ObjectNotLocked`` errors when using various commands
(including ``bzr cat`` and ``bzr annotate``) in combination with a
smart server URL. (Andrew Bennetts, #237067)
* ``FTPTransport.stat()`` would return ``0000`` as the permission bits
for the containing ``.bzr/`` directory (it does not implement
permissions). This would cause us to set all subdirectories to
``0700`` and files to ``0600`` rather than leaving them unmodified.
Now we ignore ``0000`` as the permissions and assume they are
invalid. (John Arbash Meinel, #259855)
* Merging from a previously joined branch will no longer cause
a traceback. (Jelmer Vernooij, #203376)
* Pack operations on windows network shares will work even with large
files. (Robert Collins, #255656)
* Running ``bzr st PATH_TO_TREE`` will no longer suppress merge
status. Status is also about 7% faster on mozilla sized trees
when the path to the root of the tree has been given. Users of
the internal ``show_tree_status`` function should be aware that
the show_pending flag is now authoritative for showing pending
merges, as it was originally. (Robert Collins, #225204)
* Set valid default _param_name for Option so that ListOption can embed
'-' in names. (Vincent Ladeuil, #263249)
* Show proper error rather than traceback when an unknown revision
id is specified to ``bzr cat-revision``. (Jelmer Vernooij, #175569)
* Trailing text in the dirstate file could cause the C dirstate parser
to try to allocate an invalid amount of memory. We now properly
check and test for parsing a dirstate with invalid trailing data.
(John Arbash Meinel, #186014)
* Unexpected error responses from a smart server no longer cause the
client to traceback. (Andrew Bennetts, #263527)
* Use a Windows api function to get a Unicode host name, rather than
assuming the host name is ascii.
(Mark Hammond, John Arbash Meinel, #256550)
* ``WorkingTree4`` trees will now correctly report missing-and-new
paths in the output of ``iter_changes``. (Robert Collins)
DOCUMENTATION:
* Updated developer documentation. (Martin Pool)
API CHANGES:
* Exporters now take 4 parameters. (Robert Collins)
* ``Tree.iter_changes`` will now return False for the content change
field when a file is missing in the basis tree and not present in
the target tree. Previously it returned True unconditionally.
(Robert Collins)
* The deprecated ``Branch.abspath`` and unimplemented
``Branch.rename_one`` and ``Branch.move`` were removed. (Jelmer Vernooij)
* BzrDir.clone_on_transport implementations must now accept a stacked_on
parameter. (Aaron Bentley)
* BzrDir.cloning_metadir implementations must now take a require_stacking
parameter. (Aaron Bentley)
TESTING:
* ``addCleanup`` now takes ``*arguments`` and ``**keyword_arguments``
which are then passed to the cleanup callable as it is run. In
addition, addCleanup no longer requires that the callables passed to
it be unique. (Jonathan Lange)
* Fix some tests that fail on Windows because files are deleted while
still in use.
(Mark Hammond)
* ``selftest``'s ``--starting-with`` option can now use predefined
prefixes so that one can say ``bzr selftest -s bp.loom`` instead of
``bzr selftest -s bzrlib.plugins.loom``. (Vincent Ladeuil)
* ``selftest``'s ``--starting-with`` option now accepts multiple values.
(Vincent Ladeuil)
INTERNALS:
* A new plugin interface, ``bzrlib.log.log_adapters``, has been added.
This allows dynamic log output filtering by plugins.
(Robert Collins)
* ``bzrlib.btree_index`` is now available, providing a b-tree index
layer. The design is memory conservative (limited memory cache),
faster to seek (approx 100 nodes per page, gives 100-way fan out),
and stores compressed pages allowing more keys per page.
(Robert Collins, John Arbash Meinel)
* ``bzrlib.diff.DiffTree.show_diff`` now skips changes where the kind
is unknown in both source and target.
(Robert Collins, Aaron Bentley)
* ``GraphIndexBuilder.add_node`` and ``BTreeBuilder`` have been
streamlined a bit. This should make creating large indexes faster.
(In benchmarking, it now takes less time to create a BTree index than
it takes to read the GraphIndex one.) (John Arbash Meinel)
* Mail clients for `bzr send` are now listed in a registry. This
allows plugins to add new clients by registering them with
``bzrlib.mail_client.mail_client_registry``. All of the built-in
clients now use this mechanism. (Neil Martinsen-Burrell)
bzr 1.6.1 2008-09-05
--------------------
A couple regressions were found in the 1.6 release. There was a
performance issue when using ``bzr+ssh`` to branch large repositories,
and some problems with stacking and ``rich-root`` capable repositories.
bzr 1.6.1rc2 2008-09-03
-----------------------
BUG FIXES:
* Copying between ``rich-root`` and ``rich-root-pack`` (and vice
versa) was accidentally using the inter-model fetcher, instead of
recognizing that both were 'rich root' formats.
(John Arbash Meinel, #264321)
bzr 1.6.1rc1 2008-08-29
-----------------------
This release fixes a few regressions found in the 1.6 client. Fetching
changes was using an O(N^2) buffering algorithm, so for large projects it
would cause memory thrashing. There is also a specific problem with the
``--1.6-rich-root`` format, which prevented stacking on top of
``--rich-root-pack`` repositories, and could allow users to accidentally
fetch experimental data (``-subtree``) without representing it properly.
The ``--1.6-rich-root`` format has been deprecated and users are
recommended to upgrade to ``--1.6.1-rich-root`` immediately. Also we
re-introduced a workaround for users who have repositories with incorrect
nodes (not possible if you only used official releases).
I should also clarify that none of this is data loss level issues, but
still sufficient enough to warrant an updated release.
BUG FIXES:
* ``RemoteTransport.readv()`` was being inefficient about how it
buffered the readv data and processed it. It would keep appending to
the same string (causing many copies) and then pop bytes out of the
start of the string (causing more copies).
With this patch "bzr+ssh://local" can improve dramatically,
especially for projects with large files.
(John Arbash Meinel)
* Revision texts were always meant to be stored as fulltexts. There
was a bug in a bzr.dev version that would accidentally create deltas
when copying from a Pack repo to a Knit repo. This has been fixed,
but to support those repositories, we know always request full texts
for Revision texts. (John Arbash Meinel, #261339)
* The previous ``--1.6-rich-root`` format used an incorrect xml
serializer, which would accidentally support fetching from a
repository that supported subtrees, even though the local one would
not. We deprecated that format, and introduced a new one that uses
the correct serializer ``--1.6.1-rich-root``.
(John Arbash Meinel, #262333)
bzr 1.6 2008-08-25
------------------
Finally, the long awaited bzr 1.6 has been released. This release includes
new features like Stacked Branches, improved weave merge, and an updated
server protocol (now on v3) which will allow for better cross version
compatibility. With this release we have deprecated Knit format
repositories, and recommend that users upgrade them, we will continue to
support reading and writing them for the forseeable future, but we will
not be tuning them for performance as pack repositories have proven to be
better at scaling. This will also be the first release to bundle
TortoiseBzr in the standalone Windows installer.
bzr 1.6rc5 2008-08-19
---------------------
BUG FIXES:
* Disable automatic detection of stacking based on a containing
directory of the target. It interacted badly with push, and needs a
bit more work to get the edges polished before it should happen
automatically. (John Arbash Meinel, #259275)
(This change was reverted when merged to bzr.dev)
bzr 1.6rc4 2008-08-18
---------------------
BUG FIXES:
* Fix a regression in knit => pack fetching. We had a logic
inversion, causing the fetch to insert fulltexts in random order,
rather than preserving deltas. (John Arbash Meinel, #256757)
bzr 1.6rc3 2008-08-14
---------------------
CHANGES:
* Disable reading ``.bzrrules`` as a per-branch rule preferences
file. The feature was not quite ready for a full release.
(Robert Collins)
IMPROVEMENTS:
* Update the windows installer to bundle TortoiseBzr and ``qbzr``
into the standalone installer. This will be the first official
windows release that installs Tortoise by default.
(Mark Hammond)
BUG FIXES:
* Fix a regression in ``bzr+http`` support. There was a missing
function (``_read_line``) that needed to be carried over from
``bzr+ssh`` support. (Andrew Bennetts)
* ``GraphIndex`` objects will internally read an entire index if more
than 1/20th of their keyspace is requested in a single operation.
This largely mitigates a performance regression in ``bzr log FILE``
and completely corrects the performance regression in ``bzr log``.
The regression was caused by removing an accomodation which had been
supporting the index format in use. A newer index format is in
development which is substantially faster. (Robert Collins)
bzr 1.6rc2 2008-08-13
---------------------
This release candidate has a few minor bug fixes, and some regression
fixes for Windows.
BUG FIXES:
* ``bzr upgrade`` on remote branches accessed via bzr:// and
bzr+ssh:// now works. (Andrew Bennetts)
* Change the ``get_format_description()`` strings for
``RepositoryFormatKnitPack5`` et al to be single line messages.
(Aaron Bentley)
* Fix for a regression on Win32 where we would try to call
``os.listdir()`` on a file and not catch the exception properly.
(Windows raises a different exception.) This would manifest in
places like ``bzr rm file`` or ``bzr switch``.
(Mark Hammond, John Arbash Meinel)
* ``Inventory.copy()`` was failing to set the revision property for
the root entry. (Jelmer Vernooij)
* sftp transport: added missing ``FileExists`` case to
``_translate_io_exception`` (Christophe Troestler, #123475)
* The help for ``bzr ignored`` now suggests ``bzr ls --ignored`` for
scripting use. (Robert Collins, #3834)
* The default ``annotate`` logic will now always assign the
last-modified value of a line to one of the revisions that modified
it, rather than a merge revision. This would happen when both sides
claimed to have modified the line resulting in the same text. The
choice is arbitrary but stable, so merges in different directions
will get the same results. (John Arbash Meinel, #232188)
bzr 1.6rc1 2008-08-06
---------------------
This release candidate for bzr 1.6 solidifies the new branch stacking
feature. Bazaar now recommends that users upgrade all knit repositories,
because later formats are much faster. However, we plan to continue read/write and
upgrade support for knit repostories for the forseeable future. Several
other bugs and performance issues were fixed.
CHANGES:
* Knit format repositories are deprecated and bzr will now emit
warnings whenever it encounters one. Use ``bzr upgrade`` to upgrade
knit repositories to pack format. (Andrew Bennetts)
IMPROVEMENTS:
* ``bzr check`` can now be told which elements at a location it should
check. (Daniel Watkins)
* Commit now supports ``--exclude`` (or ``-x``) to exclude some files
from the commit. (Robert Collins, #3117)
* Fetching data between repositories that have the same model but no
optimised fetcher will not reserialise all the revisions, increasing
performance. (Robert Collins, John Arbash Meinel)
* Give a more specific error when target branch is not reachable.
(James Westby)
* Implemented a custom ``walkdirs_utf8`` implementation for win32.
This uses a pyrex extension to get direct access to the
``FindFirstFileW`` style apis, rather than using ``listdir`` +
``lstat``. Shows a very strong improvement in commands like
``status`` and ``diff`` which have to iterate the working tree.
Anywhere from 2x-6x faster depending on the size of the tree (bigger
trees, bigger benefit.) (John Arbash Meinel)
* New registry for log properties handles and the method in
LongLogFormatter to display the custom properties returned by the
registered handlers. (Guillermo Gonzalez, #162469)
BUG FIXES:
* Add more tests that stacking does not create deltas spanning
physical repository boundaries.
(Martin Pool, #252428)
* Better message about incompatible repositories.
(Martin Pool, #206258)
* ``bzr branch --stacked`` ensures the destination branch format can
support stacking, even if the origin does not.
(Martin Pool)
* ``bzr export`` no longer exports ``.bzrrules``.
(Ian Clatworthy)
* ``bzr serve --directory=/`` now correctly allows the whole
filesystem to be accessed on Windows, not just the root of the drive
that Python is running from.
(Adrian Wilkins, #240910)
* Deleting directories by hand before running ``bzr rm`` will not
cause subsequent errors in ``bzr st`` and ``bzr commit``.
(Robert Collins, #150438)
* Fix a test case that was failing if encoding wasn't UTF-8.
(John Arbash Meinel, #247585)
* Fix "no buffer space available" error when branching with the new
smart server protocol to or from Windows.
(Andrew Bennetts, #246180)
* Fixed problem in branching from smart server.
(#249256, Michael Hudson, Martin Pool)
* Handle a file turning in to a directory in TreeTransform.
(James Westby, #248448)
API CHANGES:
* ``MutableTree.commit`` has an extra optional keywork parameter
``exclude`` that will be unconditionally supplied by the command
line UI - plugins that add tree formats may need an update.
(Robert Collins)
* The API minimum version for plugin compatibility has been raised to
1.6 - there are significant changes throughout the code base.
(Robert Collins)
* The generic fetch code now uses three attributes on Repository objects
to control fetch. The streams requested are controlled via :
``_fetch_order`` and ``_fetch_uses_deltas``. Setting these
appropriately allows different repository implementations to recieve
data in their optimial form. If the ``_fetch_reconcile`` is set then
a reconcile operation is triggered at the end of the fetch.
(Robert Collins)
* The ``put_on_disk`` and ``get_tar_item`` methods in
``InventoryEntry`` were deprecated. (Ian Clatworthy)
* ``Repository.is_shared`` doesn't take a read lock. It didn't
need one in the first place (nobody cached the value, and
``RemoteRepository`` wasn't taking one either). This saves a round
trip when probing Pack repositories, as they read the ``pack-names``
file when locked. And during probe, locking the repo isn't very
useful. (John Arbash Meinel)
INTERNALS:
* ``bzrlib.branchbuilder.BranchBuilder`` is now much more capable of
putting together a real history without having to create a full
WorkingTree. It is recommended that tests that are not directly
testing the WorkingTree use BranchBuilder instead. See
``BranchBuilder.build_snapshot`` or
``TestCaseWithMemoryTree.make_branch_builder``. (John Arbash Meinel)
* ``bzrlib.builtins.internal_tree_files`` broken into two giving a new
helper ``safe_relpath_files`` - used by the new ``exclude``
parameter to commit. (Robert Collins)
* Make it easier to introduce new WorkingTree formats.
(Ian Clatworthy)
* The code for exporting trees was refactored not to use the
deprecated ``InventoryEntry`` methods. (Ian Clatworthy)
* RuleSearchers return () instead of [] now when there are no matches.
(Ian Clatworthy)
bzr 1.6beta3 2008-07-17
-----------------------
This release adds a new 'stacked branches' feature allowing branches to
share storage without being in the same repository or on the same machine.
(See the user guide for more details.) It also adds a new hook, improved
weaves, aliases for related locations, faster bzr+ssh push, and several
bug fixes.
FEATURES:
* New ``pre_change_branch_tip`` hook that is called before the
branch tip is moved, while the branch is write-locked. See the User
Reference for signature details. (Andrew Bennetts)
* Rule-based preferences can now be defined for selected files in
selected branches, allowing commands and plugins to provide
custom behaviour for files matching defined patterns.
See ``Rule-based preferences`` (part of ``Configuring Bazaar``)
in the User Guide and ``bzr help rules`` for more information.
(Ian Clatworthy)
* Sites may suggest a branch to stack new branches on. (Aaron Bentley)
* Stacked branches are now supported. See ``bzr help branch`` and
``bzr help push``. Branches must be in the ``development1`` format
to stack, though the stacked-on branch can be of any format.
(Robert Collins)
IMPROVEMENTS:
* ``bzr export --format=tgz --root=NAME -`` to export a gzipped tarball
to stdout; also ``tar`` and ``tbz2``.
(Martin Pool)
* ``bzr (re)merge --weave`` will now use a standard Weave algorithm,
rather than the annotation-based merge it was using. It does so by
building up a Weave of the important texts, without needing to build
the full ancestry. (John Arbash Meinel, #238895)
* ``bzr send`` documents and better supports ``emacsclient`` (proper
escaping of mail headers and handling of the MUA Mew).
(Christophe Troestler)
* Remembered locations can be specified by aliases, e.g. :parent, :public,
:submit. (Aaron Bentley)
* The smart protocol now has improved support for setting branches'
revision info directly. This makes operations like push
faster. The new request method name is
``Branch.set_last_revision_ex``. (Andrew Bennetts)
BUG FIXES:
* Bazaar is now able to be a client to the web server of IIS 6 and 7.
The broken implementations of RFC822 in Python and RFC2046 in IIS
combined with boundary-line checking in Bazaar previously made this
impossible. (NB, IIS 5 does not suffer from this problem).
(Adrian Wilkins, #247585)
* ``bzr log --long`` with a ghost in your mainline now handles that
ghost properly. (John Arbash Meinel, #243536)
* ``check`` handles the split-up .bzr layout correctly, so no longer
requires a branch to be present.
(Daniel Watkins, #64783)
* Clearer message about how to set the PYTHONPATH if bzrlib can't be
loaded.
(Martin Pool, #205230)
* Errors about missing libraries are now shown without a traceback,
and with a suggestion to install the library. The full traceback is
still in ``.bzr.log`` and can be shown with ``-Derror``.
(Martin Pool, #240161)
* Fetch from a stacked branch copies all required data.
(Aaron Bentley, #248506)
* Handle urls such as ftp://user@host.com@www.host.com where the user
name contains an @.
(Neil Martinsen-Burrell, #228058)
* ``needs_read_lock`` and ``needs_write_lock`` now suppress an error during
``unlock`` if there was an error in the original function. This helps
most when there is a failure with a smart server action, since often the
connection closes and we cannot unlock.
(Andrew Bennetts, John Arbash Meinel, #125784)
* Obsolete hidden command ``bzr fetch`` removed.
(Martin Pool, #172870)
* Raise the correct exception when doing ``-rbefore:0`` or ``-c0``.
(John Arbash Meinel, #239933)
* You can now compare file revisions in Windows diff programs from
Cygwin Bazaar.
(Matt McClure, #209281)
* revision_history now tolerates mainline ghosts for Branch format 6.
(Aaron Bentley, #235055)
* Set locale from environment for third party libs.
(Martin von Gagern, #128496)
DOCUMENTATION:
* Added *Using stacked branches* to the User Guide.
(Ian Clatworthy)
* Updated developer documentation.
(Martin Pool)
TESTING:
* ``-Dmemory`` will cause /proc/PID/status to be catted before bzr
exits, allowing low-key analysis of peak memory use. (Robert Collins)
* ``TestCaseWithTransport.make_branch_and_tree`` tries harder to return
a tree with a ``branch`` attribute of the right format. This was
preventing some ``RemoteBranch`` tests from actually running with
``RemoteBranch`` instances. (Andrew Bennetts)
API CHANGES:
* Removed ``Repository.text_store``, ``control_store``, etc. Instead,
there are new attributes ``texts, inventories, revisions,
signatures``, each of which is a ``VersionedFiles``. See the
Repository docstring for more details.
(Robert Collins)
* ``Branch.pull`` now accepts an ``_override_hook_target`` optional
parameter. If you have a subclass of ``Branch`` that overrides
``pull`` then you should add this parameter. (Andrew Bennetts)
* ``bzrlib.check.check()`` has been deprecated in favour of the more
aptly-named ``bzrlib.check.check_branch()``.
(Daniel Watkins)
* ``Tree.print_file`` and ``Repository.print_file`` are deprecated.
These methods are bad APIs because they write directly to sys.stdout.
bzrlib does not use them internally, and there are no direct tests
for them. (Alexander Belchenko)
INTERNALS:
* ``cat`` command no longer uses ``Tree.print_file()`` internally.
(Alexander Belchenko)
* New class method ``BzrDir.open_containing_tree_branch_or_repository``
which eases the discovery of the tree, the branch and the repository
containing a given location.
(Daniel Watkins)
* New ``versionedfile.KeyMapper`` interface to abstract out the access to
underlying .knit/.kndx etc files in repositories with partitioned
storage. (Robert Collins)
* Obsolete developer-use command ``weave-join`` has been removed.
(Robert Collins)
* ``RemoteToOtherFetcher`` and ``get_data_stream_for_search`` removed,
to support new ``VersionedFiles`` layering.
(Robert Collins)
bzr 1.6beta2 2008-06-10
-----------------------
This release contains further progress towards our 1.6 goals of shallow
repositories, and contains a fix for some user-affecting bugs in the
repository layer. Building working trees during checkout and branch is
now faster.
BUG FIXES:
* Avoid KnitCorrupt error extracting inventories from some repositories.
(The data is not corrupt; an internal check is detecting a problem
reading from the repository.)
(Martin Pool, Andrew Bennetts, Robert Collins, #234748)
* ``bzr status`` was breaking if you merged the same revision twice.
(John Arbash Meinel, #235407)
* Fix infinite loop consuming 100% CPU when a connection is lost while
reading a response body via the smart protocol v1 or v2.
(Andrew Bennetts)
* Inserting a bundle which changes the contents of a file with no trailing
end of line, causing a knit snapshot in a 'knits' repository will no longer
cause KnitCorrupt. (Robert Collins)
* ``RemoteBranch.pull`` needs to return the ``self._real_branch``'s
pull result. It was instead just returning None, which breaks ``bzr
pull``. (John Arbash Meinel, #238149)
* Sanitize branch nick before using it as an attachment filename in
``bzr send``. (Lukáš Lalinský, #210218)
* Squash ``inv_entry.symlink_target`` to a plain string when
generating DirState details. This prevents from getting a
``UnicodeError`` when you have symlinks and non-ascii filenames.
(John Arbash Meinel, #135320)
IMPROVEMENTS:
* Added the 'alias' command to set/unset and display aliases. (Tim Penhey)
* ``added``, ``modified``, and ``unknowns`` behaviour made consistent (all three
now quote paths where required). Added ``--null`` option to ``added`` and
``modified`` (for null-separated unknowns, use ``ls --unknown --null``)
(Adrian Wilkins)
* Faster branching (1.09x) and lightweight checkouts (1.06x) on large trees.
(Ian Clatworthy, Aaron Bentley)
DOCUMENTATION:
* Added *Bazaar Zen* section to the User Guide. (Ian Clatworthy)
TESTING:
* Fix the test HTTPServer to be isolated from chdir calls made while it is
running, allowing it to be used in blackbox tests. (Robert Collins)
API CHANGES:
* ``WorkingTree.set_parent_(ids/trees)`` will now filter out revisions
which are in the ancestry of other revisions. So if you merge the same
tree twice, or merge an ancestor of an existing merge, it will only
record the newest. (If you merge a descendent, it will replace its
ancestor). (John Arbash Meinel, #235407)
* ``RepositoryPolicy.__init__`` now requires stack_on and stack_on_pwd,
through the derived classes do not. (Aaron Bentley)
INTERNALS:
* ``bzrlib.bzrdir.BzrDir.sprout`` now accepts ``stacked`` to control
creating stacked branches. (Robert Collins)
* Knit record serialisation is now stricter on what it will accept, to
guard against potential internal bugs, or broken input. (Robert Collins)
bzr 1.6beta1 2008-06-02
-----------------------
Commands that work on the revision history such as push, pull, missing,
uncommit and log are now substantially faster. This release adds a
translation of some of the user documentation into Spanish. (Contributions of
other translations would be very welcome.) Bazaar 1.6beta1 adds a new network
protocol which is used by default and which allows for more efficient transfers
and future extensions.
NOTES WHEN UPGRADING:
* There is a new version of the network protocol used for bzr://, bzr+ssh://
and bzr+http:// connections. This will allow more efficient requests and
responses, and more graceful fallback when a server is too old to
recognise a request from a more recent client. Bazaar 1.6 will
interoperate with 0.16 and later versions, but servers should be upgraded
when possible. Bazaar 1.6 no longer interoperates with 0.15 and earlier via
these protocols. Use alternatives like SFTP or upgrade those servers.
(Andrew Bennetts, #83935)
CHANGES:
* Deprecation warnings will not be suppressed when running ``bzr selftest``
so that developers can see if their code is using deprecated functions.
(John Arbash Meinel)
FEATURES:
* Adding ``-Derror`` will now display a traceback when a plugin fails to
load. (James Westby)
IMPROVEMENTS:
* ``bzr branch/push/pull -r XXX`` now have a helper function for finding
the revno of the new revision (``Graph.find_distance_to_null``). This
should make something like ``bzr branch -r -100`` in a shared, no-trees
repository much snappier. (John Arbash Meinel)
* ``bzr log --short -r X..Y`` no longer needs to access the full revision
history. This makes it noticeably faster when logging the last few
revisions. (John Arbash Meinel)
* ``bzr ls`` now accepts ``-V`` as an alias for ``--versioned``.
(Jerad Cramp, #165086)
* ``bzr missing`` uses the new ``Graph.find_unique_ancestors`` and
``Graph.find_differences`` to determine missing revisions without having
to search the whole ancestry. (John Arbash Meinel, #174625)
* ``bzr uncommit`` now uses partial history access, rather than always
extracting the full revision history for a branch. This makes it
resolve the appropriate revisions much faster (in testing it drops
uncommit from 1.5s => 0.4s). It also means ``bzr log --short`` is one
step closer to not using full revision history.
(John Arbash Meinel, #172649)
BUGFIXES:
* ``bzr merge --lca`` should handle when two revisions have no common
ancestor other than NULL_REVISION. (John Arbash Meinel, #235715)
* ``bzr status`` was breaking if you merged the same revision twice.
(John Arbash Meinel, #235407)
* ``bzr push`` with both ``--overwrite`` and ``-r NNN`` options no longer
fails. (Andrew Bennetts, #234229)
* Correctly track the base URL of a smart medium when using bzr+http://
URLs, which was causing spurious "No repository present" errors with
branches in shared repositories accessed over bzr+http.
(Andrew Bennetts, #230550)
* Define ``_remote_is_at_least_1_2`` on ``SmartClientMedium`` so that all
implementations have the attribute. Fixes 'PyCurlTransport' object has no
attribute '_remote_is_at_least_1_2' attribute errors.
(Andrew Bennetts, #220806)
* Failure to delete an obsolete pack file should just give a warning
message, not a fatal error. It may for example fail if the file is still
in use by another process.
(Martin Pool)
* Fix MemoryError during large fetches over HTTP by limiting the amount of
data we try to read per ``recv`` call. The problem was observed with
Windows and a proxy, but might affect other environments as well.
(Eric Holmberg, #215426)
* Handle old merge directives correctly in Merger.from_mergeable. Stricter
get_parent_map requirements exposed a latent bug here. (Aaron Bentley)
* Issue a warning and ignore passwords declared in authentication.conf when
used for an ssh scheme (sftp or bzr+ssh).
(Vincent Ladeuil, #203186)
* Make both http implementations raise appropriate exceptions on 403
Forbidden when POSTing smart requests.
(Vincent Ladeuil, #230223)
* Properly *title* header names in http requests instead of capitalizing
them.
(Vincent Ladeuil, #229076)
* The "Unable to obtain lock" error message now also suggests using
``bzr break-lock`` to fix it. (Martin Albisetti, #139202)
* Treat an encoding of '' as ascii; this can happen when bzr is run
under vim on Mac OS X.
(Neil Martinsen-Burrell)
* ``VersionedFile.make_mpdiffs()`` was raising an exception that wasn't in
scope. (Daniel Fischer #235687)
DOCUMENTATION:
* Added directory structure and started translation of docs in spanish.
(Martin Albisetti, Lucio Albenga)
* Incorporate feedback from Jelmer Vernooij and Neil Martinsen-Burrell
on the plugin and integration chapters of the User Guide.
(Ian Clatworthy)
* More Bazaar developer documentation about packaging and release process,
and about use of Python reprs.
(Martin Pool, Martin Albisetti)
* Updated Tortise strategy document. (Mark Hammond)
TESTING:
* ``bzrlib.tests.adapt_tests`` was broken and unused - it has been fixed.
(Robert Collins)
* Fix the test HTTPServer to be isolated from chdir calls made while it is
running, allowing it to be used in blackbox tests. (Robert Collins)
* New helper function for splitting test suites
``split_suite_by_condition``. (Robert Collins)
INTERNALS:
* ``Branch.missing_revisions`` has been deprecated. Similar functionality
can be obtained using ``bzrlib.missing.find_unmerged``. The api was
fairly broken, and the function was unused, so we are getting rid of it.
(John Arbash Meinel)
API CHANGES:
* ``Branch.abspath`` is deprecated; use the Tree or Transport
instead. (Martin Pool)
* ``Branch.update_revisions`` now takes an optional ``Graph``
object. This can be used by ``update_revisions`` when it is
checking ancestry, and allows callers to prefer request to go to a
local branch. (John Arbash Meinel)
* Branch, Repository, Tree and BzrDir should expose a Transport as an
attribute if they have one, rather than having it indirectly accessible
as ``.control_files._transport``. This doesn't add a requirement
to support a Transport in cases where it was not needed before;
it just simplifies the way it is reached. (Martin Pool)
* ``bzr missing --mine-only`` will return status code 0 if you have no
new revisions, but the remote does. Similarly for ``--theirs-only``.
The new code only checks one side, so it doesn't know if the other
side has changes. This seems more accurate with the request anyway.
It also changes the output to print '[This|Other] branch is up to
date.' rather than displaying nothing. (John Arbash Meinel)
* ``LockableFiles.put_utf8``, ``put_bytes`` and ``controlfilename``
are now deprecated in favor of using Transport operations.
(Martin Pool)
* Many methods on ``VersionedFile``, ``Repository`` and in
``bzrlib.revision`` deprecated before bzrlib 1.5 have been removed.
(Robert Collins)
* ``RevisionSpec.wants_revision_history`` can be set to False for a given
``RevisionSpec``. This will disable the existing behavior of passing in
the full revision history to ``self._match_on``. Useful for specs that
don't actually need access to the full history. (John Arbash Meinel)
* The constructors of ``SmartClientMedium`` and its subclasses now require a
``base`` parameter. ``SmartClientMedium`` implementations now also need
to provide a ``remote_path_from_transport`` method. (Andrew Bennetts)
* The default permissions for creating new files and directories
should now be obtained from ``BzrDir._get_file_mode()`` and
``_get_dir_mode()``, rather than from LockableFiles. The ``_set_file_mode``
and ``_set_dir_mode`` variables on LockableFiles which were advertised
as a way for plugins to control this are no longer consulted.
(Martin Pool)
* ``VersionedFile.join`` is deprecated. This method required local
instances of both versioned file objects and was thus hostile to being
used for streaming from a smart server. The new get_record_stream and
insert_record_stream are meant to efficiently replace this method.
(Robert Collins)
* ``WorkingTree.set_parent_(ids/trees)`` will now filter out revisions
which are in the ancestry of other revisions. So if you merge the same
tree twice, or merge an ancestor of an existing merge, it will only
record the newest. (If you merge a descendent, it will replace its
ancestor). (John Arbash Meinel, #235407)
* ``WorkingTreeFormat2.stub_initialize_remote`` is now private.
(Martin Pool)
bzr 1.5 2008-05-16
------------------
This release of Bazaar includes several updates to the documentation, and fixes
to prepare for making rich root support the default format. Many bugs have been
squashed, including fixes to log, bzr+ssh inter-operation with older servers.
CHANGES:
* Suppress deprecation warnings when bzrlib is a 'final' release. This way
users of packaged software won't be bothered with DeprecationWarnings,
but developers and testers will still see them. (John Arbash Meinel)
DOCUMENTATION:
* Incorporate feedback from Jelmer Vernooij and Neil Martinsen-Burrell
on the plugin and integration chapters of the User Guide.
(Ian Clatworthy)
bzr 1.5rc1 2008-05-09
---------------------
NOTES WHEN UPGRADING:
CHANGES:
* Broader support of GNU Emacs mail clients. Set
``mail_client=emacsclient`` in your bazaar.conf and ``send`` will pop the
bundle in a mail buffer according to the value of ``mail-user-agent``
variable. (Xavier Maillard)
FEATURES:
IMPROVEMENTS:
* Diff now handles revision specs like "branch:" and "submit:" more
efficiently. (Aaron Bentley, #202928)
* More friendly error given when attempt to start the smart server
on an address already in use. (Andrea Corbellini, #200575)
* Pull completes much faster when there is nothing to pull.
(Aaron Bentley)
BUGFIXES:
* Authentication.conf can define sections without password.
(Vincent Ladeuil, #199440)
* Avoid muttering every time a child update does not cause a progress bar
update. (John Arbash Meinel, #213771)
* ``Branch.reconcile()`` is now implemented. This allows ``bzr reconcile``
to fix when a Branch has a non-canonical mainline history. ``bzr check``
also detects this condition. (John Arbash Meinel, #177855)
* ``bzr log -r ..X bzr://`` was failing, because it was getting a request
for ``revision_id=None`` which was not a string.
(John Arbash Meinel, #211661)
* ``bzr commit`` now works with Microsoft's FTP service.
(Andreas Deininger)
* Catch definitions outside sections in authentication.conf.
(Vincent Ladeuil, #217650)
* Conversion from non-rich-root to rich-root(-pack) updates inventory
sha1s, even when bundles are used. (Aaron Bentley, #181391)
* Conversion from non-rich-root to rich-root(-pack) works correctly even
though search keys are not topologically sorted. (Aaron Bentley)
* Conversion from non-rich-root to rich-root(-pack) works even when a
parent revision has a different root id. (Aaron Bentley, #177874)
* Disable strace testing until strace is fixed (see bug #103133) and emit a
warning when selftest ends to remind us of leaking tests.
(Vincent Ladeuil, #226769)
* Fetching all revisions from a repository does not cause pack collisions.
(Robert Collins, Aaron Bentley, #212908)
* Fix error about "attempt to add line-delta in non-delta knit".
(Andrew Bennetts, #217701)
* Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break
if the remote server was < version 1.2. This was due to a bug in the
RemoteRepository.get_parent_map() fallback code.
(John Arbash Meinel, #214894)
* Remove leftover code in ``bzr_branch`` that inappropriately creates
a ``branch-name`` file in the branch control directory.
(Martin Pool)
* Set SO_REUSEADDR on server sockets of ``bzr serve`` to avoid problems
rebinding the socket when starting the server a second time.
(John Arbash Meinel, Martin Pool, #164288)
* Severe performance degradation in fetching from knit repositories to
knits and packs due to parsing the entire revisions.kndx on every graph
walk iteration fixed by using the Repository.get_graph API. There was
another regression in knit => knit fetching which re-read the index for
every revision each side had in common.
(Robert Collins, John Arbash Meinel)
* When logging the changes to a particular file, there was a bug if there
were ghosts in the revision ancestry. (John Arbash Meinel, #209948)
* xs4all's ftp server returns a temporary error when trying to list an
empty directory, rather than returning an empty list. Adding a
workaround so that we don't get spurious failures.
(John Arbash Meinel, #215522)
DOCUMENTATION:
* Expanded the User Guide to include new chapters on popular plugins and
integrating Bazaar into your environment. The *Best practices* chapter
was renamed to *Miscellaneous topics* as suggested by community
feedback as well. (Ian Clatworthy)
* Document outlining strategies for TortoiseBzr. (Mark Hammond)
* Improved the documentation on hooks. (Ian Clatworthy)
* Update authentication docs regarding ssh agents.
(Vincent Ladeuil, #183705)
TESTING:
* Add ``thread_name_suffix`` parameter to SmartTCPServer_for_testing, to
make it easy to identify which test spawned a thread with an unhandled
exception. (Andrew Bennetts)
* New ``--debugflag``/``-E`` option to ``bzr selftest`` for setting
options for debugging tests, these are complementary to the the -D
options. The ``-Dselftest_debug`` global option has been replaced by the
``-E=allow_debug`` option for selftest. (Andrew Bennetts)
* Parameterised test ids are preserved correctly to aid diagnosis of test
failures. (Robert Collins, Andrew Bennetts)
* selftest now accepts --starting-with <id> to load only the tests whose id
starts with the one specified. This greatly speeds up running the test
suite on a limited set of tests and can be used to run the tests for a
single module, a single class or even a single test. (Vincent Ladeuil)
* The test suite modules have been modified to define load_tests() instead
of test_suite(). That speeds up selective loading (via --load-list)
significantly and provides many examples on how to migrate (grep for
load_tests). (Vincent Ladeuil)
INTERNALS:
* ``Hooks.install_hook`` is now deprecated in favour of
``Hooks.install_named_hook`` which adds a required ``name`` parameter, to
avoid having to call ``Hooks.name_hook``. (Daniel Watkins)
* Implement xml8 serializer. (Aaron Bentley)
* New form ``@deprecated_method(deprecated_in(1, 5, 0))`` for making
deprecation wrappers. (Martin Pool)
* ``Repository.revision_parents`` is now deprecated in favour of
``Repository.get_parent_map([revid])[revid]``. (Jelmer Vernooij)
* The Python ``assert`` statement is no longer used in Bazaar source, and
a test checks this. (Martin Pool)
API CHANGES:
* ``bzrlib.status.show_pending_merges`` requires the repository to be
locked by the caller. Callers should have been doing it anyway, but it
will now raise an exception if they do not. (John Arbash Meinel)
* Repository.get_data_stream, Repository.get_data_stream_for_search(),
Repository.get_deltas_for_revsions(), Repository.revision_trees(),
Repository.item_keys_introduced_by() no longer take read locks.
(Aaron Bentley)
* ``LockableFiles.get_utf8`` and ``.get`` are deprecated, as a start
towards removing LockableFiles and ``.control_files`` entirely.
(Martin Pool)
* Methods deprecated prior to 1.1 have been removed.
(Martin Pool)
bzr 1.4 2008-04-28
------------------
This release of Bazaar includes handy improvements to the speed of log and
status, new options for several commands, improved documentation, and better
hooks, including initial code for server-side hooks. A number of bugs have
been fixed, particularly in interoperability between different formats or
different releases of Bazaar over there network. There's been substantial
internal work in both the repository and network code to enable new features
and faster performance.
BUG FIXES:
* Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break
if the remote server was < version 1.2. This was due to a bug in the
RemoteRepository.get_parent_map() fallback code.
(John Arbash Meinel, Andrew Bennetts, #214894)
bzr 1.4rc2 2008-04-21
---------------------
BUG FIXES:
* ``bzr log -r ..X bzr://`` was failing, because it was getting a request
for ``revision_id=None`` which was not a string.
(John Arbash Meinel, #211661)
* Fixed a bug in handling ghost revisions when logging changes in a
particular file. (John Arbash Meinel, #209948)
* Fix error about "attempt to add line-delta in non-delta knit".
(Andrew Bennetts, #205156)
* Fixed performance degradation in fetching from knit repositories to
knits and packs due to parsing the entire revisions.kndx on every graph
walk iteration fixed by using the Repository.get_graph API. There was
another regression in knit => knit fetching which re-read the index for
every revision each side had in common.
(Robert Collins, John Arbash Meinel)
bzr 1.4rc1 2008-04-11
---------------------
CHANGES:
* bzr main script cannot be imported (Benjamin Peterson)
* On Linux bzr additionally looks for plugins in arch-independent site
directory. (Toshio Kuratomi)
* The ``set_rh`` branch hook is now deprecated. Please migrate
any plugins using this hook to use an alternative, e.g.
``post_change_branch_tip``. (Ian Clatworthy)
* When a plugin cannot be loaded as the file path is not a valid
python module name bzr will now strip a ``bzr_`` prefix from the
front of the suggested name, as many plugins (e.g. bzr-svn)
want to be installed without this prefix. It is a common mistake
to have a folder named "bzr-svn" for that plugin, especially
as this is what bzr branch lp:bzr-svn will give you. (James Westby,
Andrew Cowie)
* UniqueIntegerBugTracker now appends bug-ids instead of joining
them to the base URL. Plugins that register bug trackers may
need a trailing / added to the base URL if one is not already there.
(James Wesby, Andrew Cowie)
FEATURES:
* Added start_commit hook for mutable trees. (Jelmer Vernooij, #186422)
* ``status`` now accepts ``--no-pending`` to show the status without
listing pending merges, which speeds up the command a lot on large
histories. (James Westby, #202830)
* New ``post_change_branch_tip`` hook that is called after the
branch tip is moved but while the branch is still write-locked.
See the User Reference for signature details.
(Ian Clatworthy, James Henstridge)
* Reconfigure can convert a branch to be standalone or to use a shared
repository. (Aaron Bentley)
IMPROVEMENTS:
* The smart protocol now has support for setting branches' revision info
directly. This should make operations like push slightly faster, and is a
step towards server-side hooks. The new request method name is
``Branch.set_last_revision_info``. (Andrew Bennetts)
* ``bzr commit --fixes`` now recognises "gnome" as a tag by default.
(James Westby, Andrew Cowie)
* ``bzr switch`` will attempt to find branches to switch to relative to the
current branch. E.g. ``bzr switch branchname`` will look for
``current_branch/../branchname``. (Robert Collins, Jelmer Vernooij,
Wouter van Heyst)
* Diff is now more specific about execute-bit changes it describes
(Chad Miller)
* Fetching data over HTTP is a bit faster when urllib is used. This is done
by forcing it to recv 64k at a time when reading lines in HTTP headers,
rather than just 1 byte at a time. (Andrew Bennetts)
* Log --short and --line are much faster when -r is not specified.
(Aaron Bentley)
* Merge is faster. We no longer check a file's existence unnecessarily
when merging the execute bit. (Aaron Bentley)
* ``bzr status`` on an explicit list of files no longer shows pending
merges, making it much faster on large trees. (John Arbash Meinel)
* The launchpad directory service now warns the user if they have not set
their launchpad login and are trying to resolve a URL using it, just
in case they want to do a write operation with it. (James Westby)
* The smart protocol client is slightly faster, because it now only queries
the server for the protocol version once per connection. Also, the HTTP
transport will now automatically probe for and use a smart server if
one is present. You can use the new ``nosmart+`` transport decorator
to get the old behaviour. (Andrew Bennetts)
* The ``version`` command takes a ``--short`` option to print just the
version number, for easier use in scripts. (Martin Pool)
* Various operations with revision specs and commands that calculate
revnos and revision ids are faster. (John A. Meinel, Aaron Bentley)
BUGFIXES:
* Add ``root_client_path`` parameter to SmartWSGIApp and
SmartServerRequest. This makes it possible to publish filesystem
locations that don't exactly match URL paths. SmartServerRequest
subclasses should use the new ``translate_client_path`` and
``transport_from_client_path`` methods when dealing with paths received
from a client to take this into account. (Andrew Bennetts, #124089)
* ``bzr mv a b`` can be now used also to rename previously renamed
directories, not only files. (Lukáš Lalinský, #107967)
* ``bzr uncommit --local`` can now remove revisions from the local
branch to be symmetric with ``bzr commit --local``.
(John Arbash Meinel, #93412)
* Don't ask for a password if there is no real terminal.
(Alexander Belchenko, #69851)
* Fix a bug causing a ValueError crash in ``parse_line_delta_iter`` when
fetching revisions from a knit to pack repository or vice versa using
bzr:// (including over http or ssh).
(#208418, Andrew Bennetts, Martin Pool, Robert Collins)
* Fixed ``_get_line`` in ``bzrlib.smart.medium``, which was buggy. Also
fixed ``_get_bytes`` in the same module to use the push back buffer.
These bugs had no known impact in normal use, but were problematic for
developers working on the code, and were likely to cause real bugs sooner
or later. (Andrew Bennetts)
* Implement handling of basename parameter for DefaultMail. (James Westby)
* Incompatibility with Paramiko versions newer than 1.7.2 was fixed.
(Andrew Bennetts, #213425)
* Launchpad locations (lp: URLs) can be pulled. (Aaron Bentley, #181945)
* Merges that add files to deleted root directories complete. They
do create conflicts. (Aaron Bentley, #210092)
* vsftp's return ``550 RNFR command failed.`` supported.
(Marcus Trautwig, #129786)
DOCUMENTATION:
* Improved documentation on send/merge relationship. (Peter Schuller)
* Minor fixes to the User Guide. (Matthew Fuller)
* Reduced the evangelism in the User Guide. (Ian Clatworthy)
* Added Integrating with Bazaar document for developers (Martin Albisetti)
API BREAKS:
* Attempting to pull data from a ghost aware repository (e.g. knits) into a
non-ghost aware repository such as weaves will now fail if there are
ghosts. (Robert Collins)
* ``KnitVersionedFile`` no longer accepts an ``access_mode`` parameter, and
now requires the ``index`` and ``access_method`` parameters to be
supplied. A compatible shim has been kept in the new function
``knit.make_file_knit``. (Robert Collins)
* Log formatters must now provide log_revision instead of show and
show_merge_revno methods. The latter had been deprecated since the 0.17
release. (James Westby)
* ``LoopbackSFTP`` is now called ``SocketAsChannelAdapter``.
(Andrew Bennetts)
* ``osutils.backup_file`` is removed. (Alexander Belchenko)
* ``Repository.get_revision_graph`` is deprecated, with no replacement
method. The method was size(history) and not desirable. (Robert Collins)
* ``revision.revision_graph`` is deprecated, with no replacement function.
The function was size(history) and not desirable. (Robert Collins)
* ``Transport.get_shared_medium`` is deprecated. Use
``Transport.get_smart_medium`` instead. (Andrew Bennetts)
* ``VersionedFile`` factories now accept a get_scope parameter rather
than using a call to ``transaction_finished``, allowing the removal of
the fixed list of versioned files per repository. (Robert Collins)
* ``VersionedFile.annotate_iter`` is deprecated. While in principle this
allowed lower memory use, all users of annotations wanted full file
annotations, and there is no storage format suitable for incremental
line-by-line annotation. (Robert Collins)
* ``VersionedFile.clone_text`` is deprecated. This performance optimisation
is no longer used - reading the content of a file that is undergoing a
file level merge to identical state on two branches is rare enough, and
not expensive enough to special case. (Robert Collins)
* ``VersionedFile.clear_cache`` and ``enable_cache`` are deprecated.
These methods added significant complexity to the ``VersionedFile``
implementation, but were only used for optimising fetches from knits -
which can be done from outside the knit layer, or via a caching
decorator. As knits are not the default format, the complexity is no
longer worth paying. (Robert Collins)
* ``VersionedFile.create_empty`` is removed. This method presupposed a
sensible mapping to a transport for individual files, but pack backed
versioned files have no such mapping. (Robert Collins)
* ``VersionedFile.get_graph`` is deprecated, with no replacement method.
The method was size(history) and not desirable. (Robert Collins)
* ``VersionedFile.get_graph_with_ghosts`` is deprecated, with no
replacement method. The method was size(history) and not desirable.
(Robert Collins)
* ``VersionedFile.get_parents`` is deprecated, please use
``VersionedFile.get_parent_map``. (Robert Collins)
* ``VersionedFile.get_sha1`` is deprecated, please use
``VersionedFile.get_sha1s``. (Robert Collins)
* ``VersionedFile.has_ghost`` is now deprecated, as it is both expensive
and unused outside of a single test. (Robert Collins)
* ``VersionedFile.iter_parents`` is now deprecated in favour of
``get_parent_map`` which can be used to instantiate a Graph on a
VersionedFile. (Robert Collins)
* ``VersionedFileStore`` no longer uses the transaction parameter given
to most methods; amongst other things this means that the
get_weave_or_empty method no longer guarantees errors on a missing weave
in a readonly transaction, and no longer caches versioned file instances
which reduces memory pressure (but requires more careful management by
callers to preserve performance). (Robert Collins)
TESTING:
* New -Dselftest_debug flag disables clearing of the debug flags during
tests. This is useful if you want to use e.g. -Dhpss to help debug a
failing test. Be aware that using this feature is likely to cause
spurious test failures if used with the full suite. (Andrew Bennetts)
* selftest --load-list now uses a new more agressive test loader that will
avoid loading unneeded modules and building their tests. Plugins can use
this new loader by defining a load_tests function instead of a test_suite
function. (a forthcoming patch will provide many examples on how to
implement this).
(Vincent Ladeuil)
* selftest --load-list now does some sanity checks regarding duplicate test
IDs and tests present in the list but not found in the actual test suite.
(Vincent Ladeuil)
* Slightly more concise format for the selftest progress bar, so there's
more space to show the test name. (Martin Pool) ::
[2500/10884, 1fail, 3miss in 1m29s] test_revisionnamespaces.TestRev
* The test suite takes much less memory to run, and is a bit faster. This
is done by clearing most attributes of TestCases after running them, if
they succeeded. (Andrew Bennetts)
INTERNALS:
* Added ``_build_client_protocol`` to ``_SmartClient``. (Andrew Bennetts)
* Added basic infrastructure for automatic plugin suggestion.
(Martin Albisetti)
* If a ``LockableFiles`` object is not explicitly unlocked (for example
because of a missing ``try/finally`` block, it will give a warning but
not automatically unlock itself. (Previously they did.) This
sometimes caused knock-on errors if for example the network connection
had already failed, and should not be relied upon by code.
(Martin Pool, #109520)
* ``make dist`` target to build a release tarball, and also
``check-dist-tarball`` and ``dist-upload-escudero``. (Martin Pool)
* The ``read_response_tuple`` method of ``SmartClientRequestProtocol*``
classes will now raise ``UnknownSmartMethod`` when appropriate, so that
callers don't need to try distinguish unknown request errors from other
errors. (Andrew Bennetts)
* ``set_make_working_trees`` is now implemented provided on all repository
implementations (Aaron Bentley)
* ``VersionedFile`` now has a new method ``get_parent_map`` which, like
``Graph.get_parent_map`` returns a dict of key:parents. (Robert Collins)
bzr 1.3.1 2008-04-09
--------------------
No changes from 1.3.1rc1.
bzr 1.3rc1 2008-04-04
---------------------
BUG FIXES:
* Fix a bug causing a ValueError crash in ``parse_line_delta_iter`` when
fetching revisions from a knit to pack repository or vice versa using
bzr:// (including over http or ssh).
(#208418, Andrew Bennetts, Martin Pool, Robert Collins)
bzr 1.3 2008-03-20
------------------
Bazaar has become part of the GNU project <http://www.gnu.org>
Many operations that act on history, including ``log`` and ``annotate`` are now
substantially faster. Several bugs have been fixed and several new options and
features have been added.
TESTING:
* Avoid spurious failure of ``TestVersion.test_version`` matching
directory names.
(#202778, Martin Pool)
bzr 1.3rc1 2008-03-16
---------------------
NOTES WHEN UPGRADING:
* The backup directory created by ``upgrade`` is now called
``backup.bzr``, not ``.bzr.backup``. (Martin Albisetti)
CHANGES:
* A new repository format 'development' has been added. This format will
represent the latest 'in-progress' format that the bzr developers are
interested in getting early-adopter testing and feedback on.
``doc/developers/development-repo.txt`` has detailed information.
(Robert Collins)
* BZR_LOG environment variable controls location of .bzr.log trace file.
User can suppress writing messages to .bzr.log by using '/dev/null'
filename (on Linux) or 'NUL' (on Windows). If BZR_LOG variable
is not defined but BZR_HOME is defined then default location
for .bzr.log trace file is ``$BZR_HOME/.bzr.log``.
(Alexander Belchenko, #106117)
* ``launchpad`` builtin plugin now shipped as separate part in standalone
bzr.exe, installed to ``C:\Program Files\Bazaar\plugins`` directory,
and standalone installer allows user to skip installation of this plugin.
(Alexander Belchenko)
* Restore auto-detection of plink.exe on Windows. (Dmitry Vasiliev)
* Version number is now shown as "1.2" or "1.2pr2", without zeroed or
missing final fields. (Martin Pool)
FEATURES:
* ``branch`` and ``checkout`` can hard-link working tree files, which is
faster and saves space. (Aaron Bentley)
* ``bzr send`` will now also look at the ``child_submit_to`` setting in
the submit branch to determine the email address to send to.
(Jelmer Vernooij)
IMPROVEMENTS:
* BzrBranch._lefthand_history is faster on pack repos. (Aaron Bentley)
* Branch6.generate_revision_history is faster. (Aaron Bentley)
* Directory services can now be registered, allowing special URLs to be
dereferenced into real URLs. This is a generalization and cleanup of
the lp: transport lookup. (Aaron Bentley)
* Merge directives that are automatically attached to emails have nicer
filenames, based on branch-nick + revno. (Aaron Bentley)
* ``push`` has a ``--revision`` option, to specify what revision to push up
to. (Daniel Watkins)
* Significantly reducing execution time and network traffic for trivial
case of running ``bzr missing`` command for two identical branches.
(Alexander Belchenko)
* Speed up operations that look at the revision graph (such as 'bzr log').
``KnitPackRepositor.get_revision_graph`` uses ``Graph.iter_ancestry`` to
extract the revision history. This allows filtering ghosts while
stepping instead of needing to peek ahead. (John Arbash Meinel)
* The ``hooks`` command lists installed hooks, to assist in debugging.
(Daniel Watkins)
* Updates to how ``annotate`` work. Should see a measurable improvement in
performance and memory consumption for file with a lot of merges.
Also, correctly handle when a line is introduced by both parents (it
should be attributed to the first merge which notices this, and not
to all subsequent merges.) (John Arbash Meinel)
BUGFIXES:
* Autopacking no longer holds the full set of inventory lines in
memory while copying. For large repositories, this can amount to
hundreds of MB of ram consumption.
(Ian Clatworthy, John Arbash Meinel)
* Cherrypicking when using ``--format=merge3`` now explictly excludes
BASE lines. (John Arbash Meinel, #151731)
* Disable plink's interactive prompt for password.
(#107593, Dmitry Vasiliev)
* Encode command line arguments from unicode to user_encoding before
invoking external mail client in `bzr send` command.
(#139318, Alexander Belchenko)
* Fixed problem connecting to ``bzr+https://`` servers.
(#198793, John Ferlito)
* Improved error reporting in the Launchpad plugin. (Daniel Watkins,
#196618)
* Include quick-start-summary.svg file to python-based installer(s)
for Windows. (#192924, Alexander Belchenko)
* lca merge now respects specified files. (Aaron Bentley)
* Make version-info --custom imply --all. (#195560, James Westby)
* ``merge --preview`` now works for merges that add or modify
symlinks (James Henstridge)
* Redirecting the output from ``bzr merge`` (when the remembered
location is used) now works. (John Arbash Meinel)
* setup.py script explicitly checks for Python version.
(Jari Aalto, Alexander Belchenko, #200569)
* UnknownFormatErrors no longer refer to branches regardless of kind of
unknown format. (Daniel Watkins, #173980)
* Upgrade bundled ConfigObj to version 4.5.2, which properly quotes #
signs, among other small improvements. (Matt Nordhoff, #86838)
* Use correct indices when emitting LCA conflicts. This fixes IndexError
errors. (Aaron Bentley, #196780)
DOCUMENTATION:
* Explained how to use ``version-info --custom`` in the User Guide.
(Neil Martinsen-Burrell)
API BREAKS:
* Support for loading plugins from zip files and
``bzrlib.plugin.load_from_zip()`` function are deprecated.
(Alexander Belchenko)
TESTING:
* Added missing blackbox tests for ``modified`` (Adrian Wilkins)
* The branch interface tests were invalid for branches using rich-root
repositories because the empty string is not a valid file-id.
(Robert Collins)
INTERNALS:
* ``Graph.iter_ancestry`` returns the ancestry of revision ids. Similar to
``Repository.get_revision_graph()`` except it includes ghosts and you can
stop part-way through. (John Arbash Meinel)
* New module ``tools/package_mf.py`` provide custom module finder for
python packages (improves standard python library's modulefinder.py)
used by ``setup.py`` script while building standalone bzr.exe.
(Alexander Belchenko)
* New remote method ``RemoteBzrDir.find_repositoryV2`` adding support for
detecting external lookup support on remote repositories. This method is
now attempted first when lookup up repositories, leading to an extra
round trip on older bzr smart servers. (Robert Collins)
* Repository formats have a new supported-feature attribute
``supports_external_lookups`` used to indicate repositories which support
falling back to other repositories when they have partial data.
(Robert Collins)
* ``Repository.get_revision_graph_with_ghosts`` and
``bzrlib.revision.(common_ancestor,MultipleRevisionSources,common_graph)``
have been deprecated. (John Arbash Meinel)
* ``Tree.iter_changes`` is now a public API, replacing the work-in-progress
``Tree._iter_changes``. The api is now considered stable and ready for
external users. (Aaron Bentley)
* The bzrdir format registry now accepts an ``alias`` keyword to
register_metadir, used to indicate that a format name is an alias for
some other format and thus should not be reported when describing the
format. (Robert Collins)
bzr 1.2 2008-02-15
------------------
BUG FIXES:
* Fix failing test in Launchpad plugin. (Martin Pool)
bzr 1.2rc1 2008-02-13
---------------------
NOTES WHEN UPGRADING:
* Fetching via the smart protocol may need to reconnect once during a fetch
if the remote server is running Bazaar 1.1 or earlier, because the client
attempts to use more efficient requests that confuse older servers. You
may be required to re-enter a password or passphrase when this happens.
This won't happen if the server is upgraded to Bazaar 1.2.
(Andrew Bennetts)
CHANGES:
* Fetching via bzr+ssh will no longer fill ghosts by default (this is
consistent with pack-0.92 fetching over SFTP). (Robert Collins)
* Formatting of ``bzr plugins`` output is changed to be more human-
friendly. Full path of plugins locations will be shown only with
``--verbose`` command-line option. (Alexander Belchenko)
* ``merge`` now prefers to use the submit branch, but will fall back to
parent branch. For many users, this has no effect. But some users who
pull and merge on the same branch will notice a change. This change
makes it easier to work on a branch on two different machines, pulling
between the machines, while merging from the upstream.
``merge --remember`` can now be used to set the submit_branch.
(Aaron Bentley)
FEATURES:
* ``merge --preview`` produces a diff of the changes merge would make,
but does not actually perform the merge. (Aaron Bentley)
* New smart method ``Repository.get_parent_map`` for getting revision
parent data. This returns additional parent information topologically
adjacent to the requested data to reduce round trip latency impacts.
(Robert Collins)
* New smart method, ``Repository.stream_revisions_chunked``, for fetching
revision data that streams revision data via a chunked encoding. This
avoids buffering large amounts of revision data on the server and on the
client, and sends less data to the server to request the revisions.
(Andrew Bennetts, Robert Collins, #178353)
* The launchpad plugin now handles lp urls of the form
``lp://staging/``, ``lp://demo/``, ``lp://dev/`` to use the appropriate
launchpad instance to do the resolution of the branch identities.
This is primarily of use to Launchpad developers, but can also
be used by other users who want to try out Launchpad as
a branch location without messing up their public Launchpad
account. Branches that are pushed to the staging environment
have an expected lifetime of one day. (Tim Penhey)
IMPROVEMENTS:
* Creating a new branch no longer tries to read the entire revision-history
unnecessarily over smart server operations. (Robert Collins)
* Fetching between different repository formats with compatible models now
takes advantage of the smart method to stream revisions. (Andrew Bennetts)
* The ``--coverage`` option is now global, rather specific to ``bzr
selftest``. (Andrew Bennetts)
* The ``register-branch`` command will now use the public url of the branch
containing the current directory, if one has been set and no explicit
branch is provided. (Robert Collins)
* Tweak the ``reannotate`` code path to optimize the 2-parent case.
Speeds up ``bzr annotate`` with a pack repository by approx 3:2.
(John Arbash Meinel)
BUGFIXES:
* Calculate remote path relative to the shared medium in _SmartClient. This
is related to the problem in bug #124089. (Andrew Bennetts)
* Cleanly handle connection errors in smart protocol version two, the same
way as they are handled by version one. (Andrew Bennetts)
* Clearer error when ``version-info --custom`` is used without
``--template`` (Lukáš Lalinský)
* Don't raise UnavailableFeature during test setup when medusa is not
available or tearDown is never called leading to nasty side effects.
(#137823, Vincent Ladeuil)
* If a plugin's test suite cannot be loaded, for example because of a syntax
error in the tests, then ``selftest`` fails, rather than just printing
a warning. (Martin Pool, #189771)
* List possible values for BZR_SSH environment variable in env-variables
help topic. (Alexander Belchenko, #181842)
* New methods ``push_log_file`` and ``pop_log_file`` to intercept messages:
popping the log redirection now precisely restores the previous state,
which makes it easier to use bzr log output from other programs.
TestCaseInTempDir no longer depends on a log redirection being established
by the test framework, which lets bzr tests cleanly run from a normal
unittest runner.
(#124153, #124849, Martin Pool, Jonathan Lange)
* ``pull --quiet`` is now more quiet, in particular a message is no longer
printed when the remembered pull location is used. (James Westby,
#185907)
* ``reconfigure`` can safely be interrupted while fetching.
(Aaron Bentley, #179316)
* ``reconfigure`` preserves tags when converting to and from lightweight
checkouts. (Aaron Bentley, #182040)
* Stop polluting /tmp when running selftest.
(Vincent Ladeuil, #123623)
* Switch from NFKC => NFC for normalization checks. NFC allows a few
more characters which should be considered valid.
(John Arbash Meinel, #185458)
* The launchpad plugin now uses the ``edge`` xmlrpc server to avoid
interacting badly with a bug on the launchpad side. (Robert Collins)
* Unknown hostnames when connecting to a ``bzr://`` URL no longer cause
tracebacks. (Andrew Bennetts, #182849)
API BREAKS:
* Classes implementing Merge types like Merge3Merger must now accept (and
honour) a do_merge flag in their constructor. (Aaron Bentley)
* ``Repository.add_inventory`` and ``add_revision`` now require the caller
to previously take a write lock (and start a write group.)
(Martin Pool)
TESTING:
* selftest now accepts --load-list <file> to load a test id list. This
speeds up running the test suite on a limited set of tests.
(Vincent Ladeuil)
INTERNALS:
* Add a new method ``get_result`` to graph search objects. The resulting
``SearchResult`` can be used to recreate the search later, which will
be useful in reducing network traffic. (Robert Collins)
* Use convenience function to check whether two repository handles
are referring to the same repository in ``Repository.get_graph``.
(Jelmer Vernooij, #187162)
* Fetching now passes the find_ghosts flag through to the
``InterRepository.missing_revision_ids`` call consistently for all
repository types. This will enable faster missing revision discovery with
bzr+ssh. (Robert Collins)
* Fix error handling in Repository.insert_data_stream. (Lukas Lalinsky)
* ``InterRepository.missing_revision_ids`` is now deprecated in favour of
``InterRepository.search_missing_revision_ids`` which returns a
``bzrlib.graph.SearchResult`` suitable for making requests from the smart
server. (Robert Collins)
* New error ``NoPublicBranch`` for commands that need a public branch to
operate. (Robert Collins)
* New method ``iter_inventories`` on Repository for access to many
inventories. This is primarily used by the ``revision_trees`` method, as
direct access to inventories is discouraged. (Robert Collins)
* New method ``next_with_ghosts`` on the Graph breadth-first-search objects
which will split out ghosts and present parents into two separate sets,
useful for code which needs to be aware of ghosts (e.g. fetching data
cares about ghosts during revision selection). (Robert Collins)
* Record a timestamp against each mutter to the trace file, relative to the
first import of bzrlib. (Andrew Bennetts)
* ``Repository.get_data_stream`` is now deprecated in favour of
``Repository.get_data_stream_for_search`` which allows less network
traffic when requesting data streams over a smart server. (Robert Collins)
* ``RemoteBzrDir._get_tree_branch`` no longer triggers ``_ensure_real``,
removing one round trip on many network operations. (Robert Collins)
* RemoteTransport's ``recommended_page_size`` method now returns 64k, like
SFTPTransport and HttpTransportBase. (Andrew Bennetts)
* Repository has a new method ``has_revisions`` which signals the presence
of many revisions by returning a set of the revisions listed which are
present. This can be done by index queries without reading data for parent
revision names etc. (Robert Collins)
bzr 1.1 2008-01-15
------------------
(no changes from 1.1rc1)
bzr 1.1rc1 2008-01-05
---------------------
CHANGES:
* Dotted revision numbers have been revised. Instead of growing longer with
nested branches the branch number just increases. (eg instead of 1.1.1.1.1
we now report 1.2.1.) This helps scale long lived branches which have many
feature branches merged between them. (John Arbash Meinel)
* The syntax ``bzr diff branch1 branch2`` is no longer supported.
Use ``bzr diff branch1 --new branch2`` instead. This change has
been made to remove the ambiguity where ``branch2`` is in fact a
specific file to diff within ``branch1``.
FEATURES:
* New option to use custom template-based formats in ``bzr version-info``.
(Lukáš Lalinský)
* diff '--using' allows an external diff tool to be used for files.
(Aaron Bentley)
* New "lca" merge-type for fast everyday merging that also supports
criss-cross merges. (Aaron Bentley)
IMPROVEMENTS:
* ``annotate`` now doesn't require a working tree. (Lukáš Lalinský,
#90049)
* ``branch`` and ``checkout`` can now use files from a working tree to
to speed up the process. For checkout, this requires the new
--files-from flag. (Aaron Bentley)
* ``bzr diff`` now sorts files in alphabetical order. (Aaron Bentley)
* ``bzr diff`` now works on branches without working trees. Tree-less
branches can also be compared to each other and to working trees using
the new diff options ``--old`` and ``--new``. Diffing between branches,
with or without trees, now supports specific file filtering as well.
(Ian Clatworthy, #6700)
* ``bzr pack`` now orders revision texts in topological order, with newest
at the start of the file, promoting linear reads for ``bzr log`` and the
like. This partially fixes #154129. (Robert Collins)
* Merge directives now fetch prerequisites from the target branch if
needed. (Aaron Bentley)
* pycurl now handles digest authentication.
(Vincent Ladeuil)
* ``reconfigure`` can now convert from repositories. (Aaron Bentley)
* ``-l`` is now a short form for ``--limit`` in ``log``. (Matt Nordhoff)
* ``merge`` now warns when merge directives cause cherrypicks.
(Aaron Bentley)
* ``split`` now supported, to enable splitting large trees into smaller
pieces. (Aaron Bentley)
BUGFIXES:
* Avoid AttributeError when unlocking a pack repository when an error occurs.
(Martin Pool, #180208)
* Better handle short reads when processing multiple range requests.
(Vincent Ladeuil, #179368)
* build_tree acceleration uses the correct path when a file has been moved.
(Aaron Bentley)
* ``commit`` now succeeds when a checkout and its master branch share a
repository. (Aaron Bentley, #177592)
* Fixed error reporting of unsupported timezone format in
``log --timezone``. (Lukáš Lalinský, #178722)
* Fixed Unicode encoding error in ``ignored`` when the output is
redirected to a pipe. (Lukáš Lalinský)
* Fix traceback when sending large response bodies over the smart protocol
on Windows. (Andrew Bennetts, #115781)
* Fix ``urlutils.relative_url`` for the case of two ``file:///`` URLs
pointed to different logical drives on Windows.
(Alexander Belchenko, #90847)
* HTTP test servers are now compatible with the http protocol version 1.1.
(Vincent Ladeuil, #175524)
* _KnitParentsProvider.get_parent_map now handles requests for ghosts
correctly, instead of erroring or attributing incorrect parents to ghosts.
(Aaron Bentley)
* ``merge --weave --uncommitted`` now works. (Aaron Bentley)
* pycurl authentication handling was broken and incomplete. Fix handling of
user:pass embedded in the urls.
(Vincent Ladeuil, #177643)
* Files inside non-directories are now handled like other conflict types.
(Aaron Bentley, #177390)
* ``reconfigure`` is able to convert trees into lightweight checkouts.
(Aaron Bentley)
* Reduce lockdir timeout to 0 when running ``bzr serve``. (Andrew Bennetts,
#148087)
* Test that the old ``version_info_format`` functions still work, even
though they are deprecated. (John Arbash Meinel, ShenMaq, #177872)
* Transform failures no longer cause ImmortalLimbo errors (Aaron Bentley,
#137681)
* ``uncommit`` works even when the commit messages of revisions to be
removed use characters not supported in the terminal encoding.
(Aaron Bentley)
* When dumb http servers return whole files instead of the requested ranges,
read the remaining bytes by chunks to avoid overflowing network buffers.
(Vincent Ladeuil, #175886)
DOCUMENTATION:
* Minor tweaks made to the bug tracker integration documentation.
(Ian Clatworthy)
* Reference material has now be moved out of the User Guide and added
to the User Reference. The User Reference has gained 4 sections as
a result: Authenication Settings, Configuration Settings, Conflicts
and Hooks. All help topics are now dumped into text format in the
doc/en/user-reference directory for those who like browsing that
information in their editor. (Ian Clatworthy)
* *Using Bazaar with Launchpad* tutorial added. (Ian Clatworthy)
INTERNALS:
* find_* methods available for BzrDirs, Branches and WorkingTrees.
(Aaron Bentley)
* Help topics can now be loaded from files.
(Ian Clatworthy, Alexander Belchenko)
* get_parent_map now always provides tuples as its output. (Aaron Bentley)
* Parent Providers should now implement ``get_parent_map`` returning a
dictionary instead of ``get_parents`` returning a list.
``Graph.get_parents`` is now deprecated. (John Arbash Meinel,
Robert Collins)
* Patience Diff now supports arbitrary python objects, as long as they
support ``hash()``. (John Arbash Meinel)
* Reduce selftest overhead to establish test names by memoization.
(Vincent Ladeuil)
API BREAKS:
TESTING:
* Modules can now customise their tests by defining a ``load_tests``
attribute. ``pydoc bzrlib.tests.TestUtil.TestLoader.loadTestsFromModule``
for the documentation on this attribute. (Robert Collins)
* New helper function ``bzrlib.tests.condition_id_re`` which helps
filter tests based on a regular expression search on the tests id.
(Robert Collins)
* New helper function ``bzrlib.tests.condition_isinstance`` which helps
filter tests based on class. (Robert Collins)
* New helper function ``bzrlib.tests.exclude_suite_by_condition`` which
generalises the ``exclude_suite_by_re`` function. (Robert Collins)
* New helper function ``bzrlib.tests.filter_suite_by_condition`` which
generalises the ``filter_suite_by_re`` function. (Robert Collins)
* New helper method ``bzrlib.tests.exclude_tests_by_re`` which gives a new
TestSuite that does not contain tests from the input that matched a
regular expression. (Robert Collins)
* New helper method ``bzrlib.tests.randomize_suite`` which returns a
randomized copy of the input suite. (Robert Collins)
* New helper method ``bzrlib.tests.split_suite_by_re`` which splits a test
suite into two according to a regular expression. (Robert Collins)
* Parametrize all http tests for the transport implementations, the http
protocol versions (1.0 and 1.1) and the authentication schemes.
(Vincent Ladeuil)
* The ``exclude_pattern`` and ``random_order`` parameters to the function
``bzrlib.tests.filter_suite_by_re`` have been deprecated. (Robert Collins)
* The method ``bzrlib.tests.sort_suite_by_re`` has been deprecated. It is
replaced by the new helper methods added in this release. (Robert Collins)
bzr 1.0 2007-12-14
------------------
DOCUMENTATION:
* More improvements and fixes to the User Guide. (Ian Clatworthy)
* Add information on cherrypicking/rebasing to the User Guide.
(Ian Clatworthy)
* Improve bug tracker integration documentation. (Ian Clatworthy)
* Minor edits to ``Bazaar in five minutes`` from David Roberts and
to the rebasing section of the User Guide from Aaron Bentley.
(Ian Clatworthy)
bzr 1.0rc3 2007-12-11
---------------------
CHANGES:
* If a traceback occurs, users are now asked to report the bug
through Launchpad (https://bugs.launchpad.net/bzr/), rather than
by mail to the mailing list.
(Martin Pool)
BUGFIXES:
* Fix Makefile rules for doc generation. (Ian Clatworthy, #175207)
* Give more feedback during long http downloads by making readv deliver data
as it arrives for urllib, and issue more requests for pycurl. High latency
networks are better handled by urllib, the pycurl implementation give more
feedback but also incur more latency.
(Vincent Ladeuil, #173010)
* Implement _make_parents_provider on RemoteRepository, allowing generating
bundles against branches on a smart server. (Andrew Bennetts, #147836)
DOCUMENTATION:
* Improved user guide. (Ian Clatworthy)
* The single-page quick reference guide is now available as a PDF.
(Ian Clatworthy)
INTERNALS:
* readv urllib http implementation is now a real iterator above the
underlying socket and deliver data as soon as it arrives. 'get' still
wraps its output in a StringIO.
(Vincent Ladeuil)
bzr 1.0rc2 2007-12-07
---------------------
IMPROVEMENTS:
* Added a --coverage option to selftest. (Andrew Bennetts)
* Annotate merge (merge-type=weave) now supports cherrypicking.
(Aaron Bentley)
* ``bzr commit`` now doesn't print the revision number twice. (Matt
Nordhoff, #172612)
* New configuration option ``bugtracker_<tracker_abbrevation>_url`` to
define locations of bug trackers that are not directly supported by
bzr or a plugin. The URL will be treated as a template and ``{id}``
placeholders will be replaced by specific bug IDs. (Lukáš Lalinský)
* Support logging single merge revisions with short and line log formatters.
(Kent Gibson)
* User Guide enhanced with suggested readability improvements from
Matt Revell and corrections from John Arbash Meinel. (Ian Clatworthy)
* Quick Start Guide renamed to Quick Start Card, moved down in
the catalog, provided in pdf and png format and updated to refer
to ``send`` instead of ``bundle``. (Ian Clatworthy, #165080)
* ``switch`` can now be used on heavyweight checkouts as well as
lightweight ones. After switching a heavyweight checkout, the
local branch is a mirror/cache of the new bound branch and
uncommitted changes in the working tree are merged. As a safety
check, if there are local commits in a checkout which have not
been committed to the previously bound branch, then ``switch``
fails unless the ``--force`` option is given. This option is
now also required if the branch a lightweight checkout is pointing
to has been moved. (Ian Clatworthy)
INTERNALS:
* New -Dhttp debug option reports http connections, requests and responses.
(Vincent Ladeuil)
* New -Dmerge debug option, which emits merge plans for merge-type=weave.
BUGFIXES:
* Better error message when running ``bzr cat`` on a non-existant branch.
(Lukáš Lalinský, #133782)
* Catch OSError 17 (file exists) in final phase of tree transform and show
filename to user.
(Alexander Belchenko, #111758)
* Catch ShortReadvErrors while using pycurl. Also make readv more robust by
allowing multiple GET requests to be issued if too many ranges are
required.
(Vincent Ladeuil, #172701)
* Check for missing basis texts when fetching from packs to packs.
(John Arbash Meinel, #165290)
* Fall back to showing e-mail in ``log --short/--line`` if the
committer/author has only e-mail. (Lukáš Lalinský, #157026)
API BREAKS:
* Deprecate not passing a ``location`` argument to commit reporters'
``started`` methods. (Matt Nordhoff)
bzr 1.0rc1 2007-11-30
---------------------
NOTES WHEN UPGRADING:
* The default repository format is now ``pack-0.92``. This
default is used when creating new repositories with ``init`` and
``init-repo``, and when branching over bzr+ssh or bzr+hpss.
(See https://bugs.launchpad.net/bugs/164626)
This format can be read and written by Bazaar 0.92 and later, and
data can be transferred to and from older formats.
To upgrade, please reconcile your repository (``bzr reconcile``), and then
upgrade (``bzr upgrade``).
``pack-0.92`` offers substantially better scaling and performance than the
previous knits format. Some operations are slower where the code already
had bad scaling characteristics under knits, the pack format makes such
operations more visible as part of being more scalable overall. We will
correct such operations over the coming releases and encourage the filing
of bugs on any operation which you observe to be slower in a packs
repository. One particular case that we do not intend to fix is pulling
data from a pack repository into a knit repository over a high latency
link; downgrading such data requires reinsertion of the file texts, and
this is a classic space/time tradeoff. The current implementation is
conservative on memory usage because we need to support converting data
from any tree without problems.
(Robert Collins, Martin Pool, #164476)
CHANGES:
* Disable detection of plink.exe as possible ssh vendor. Plink vendor
still available if user selects it explicitly with BZR_SSH environment
variable. (Alexander Belchenko, workaround for bug #107593)
* The pack format is now accessible as "pack-0.92", or "pack-0.92-subtree"
to enable the subtree functions (for example, for bzr-svn).
See http://doc.bazaar-vcs.org/latest/developer/packrepo.html
(Martin Pool)
FEATURES:
* New ``authentication.conf`` file holding the password or other credentials
for remote servers. This can be used for ssh, sftp, smtp and other
supported transports.
(Vincent Ladeuil)
* New rich-root and rich-root-pack formats, recording the same data about
tree roots that's recorded for all other directories.
(Aaron Bentley, #164639)
* ``pack-0.92`` repositories can now be reconciled.
(Robert Collins, #154173)
* ``switch`` command added for changing the branch a lightweight checkout
is associated with and updating the tree to reflect the latest content
accordingly. This command was previously part of the BzrTools plug-in.
(Ian Clatworthy, Aaron Bentley, David Allouche)
* ``reconfigure`` command can now convert branches, trees, or checkouts to
lightweight checkouts. (Aaron Bentley)
PERFORMANCE:
* Commit updates the state of the working tree via a delta rather than
supplying entirely new basis trees. For commit of a single specified file
this reduces the wall clock time for commit by roughly a 30%.
(Robert Collins, Martin Pool)
* Commit with many automatically found deleted paths no longer performs
linear scanning for the children of those paths during inventory
iteration. This should fix commit performance blowing out when many such
paths occur during commit. (Robert Collins, #156491)
* Fetch with pack repositories will no longer read the entire history graph.
(Robert Collins, #88319)
* Revert takes out an appropriate lock when reverting to a basis tree, and
does not read the basis inventory twice. (Robert Collins)
* Diff does not require an inventory to be generated on dirstate trees.
(Aaron Bentley, #149254)
* New annotate merge (--merge-type=weave) implementation is fast on
versionedfiles withough cached annotations, e.g. pack-0.92.
(Aaron Bentley)
IMPROVEMENTS:
* ``bzr merge`` now warns when it encounters a criss-cross merge.
(Aaron Bentley)
* ``bzr send`` now doesn't require the target e-mail address to be
specified on the command line if an interactive e-mail client is used.
(Lukáš Lalinský)
* ``bzr tags`` now prints the revision number for each tag, instead of
the revision id, unless --show-ids is passed. In addition, tags can be
sorted chronologically instead of lexicographically with --sort=time.
(Adeodato Simó, #120231)
* Windows standalone version of bzr is able to load system-wide plugins from
"plugins" subdirectory in installation directory. In addition standalone
installer write to the registry (HKLM\SOFTWARE\Bazaar) useful info
about paths and bzr version. (Alexander Belchenko, #129298)
DOCUMENTATION:
BUG FIXES:
* A progress bar has been added for knitpack -> knitpack fetching.
(Robert Collins, #157789, #159147)
* Branching from a branch via smart server now preserves the repository
format. (Andrew Bennetts, #164626)
* ``commit`` is now able to invoke an external editor in a non-ascii
directory. (Daniel Watkins, #84043)
* Catch connection errors for ftp.
(Vincent Ladeuil, #164567)
* ``check`` no longer reports spurious unreferenced text versions.
(Robert Collins, John A Meinel, #162931, #165071)
* Conflicts are now resolved recursively by ``revert``.
(Aaron Bentley, #102739)
* Detect invalid transport reuse attempts by catching invalid URLs.
(Vincent Ladeuil, #161819)
* Deleting a file without removing it shows a correct diff, not a traceback.
(Aaron Bentley)
* Do no use timeout in HttpServer anymore.
(Vincent Ladeuil, #158972).
* Don't catch the exceptions related to the http pipeline status before
retrying an http request or some programming errors may be masked.
(Vincent Ladeuil, #160012)
* Fix ``bzr rm`` to not delete modified and ignored files.
(Lukáš Lalinský, #172598)
* Fix exception when revisionspec contains merge revisons but log
formatter doesn't support merge revisions. (Kent Gibson, #148908)
* Fix exception when ScopeReplacer is assigned to before any members have
been retrieved. (Aaron Bentley)
* Fix multiple connections during checkout --lightweight.
(Vincent Ladeuil, #159150)
* Fix possible error in insert_data_stream when copying between
pack repositories over bzr+ssh or bzr+http.
KnitVersionedFile.get_data_stream now makes sure that requested
compression parents are sent before any delta hunks that depend
on them.
(Martin Pool, #164637)
* Fix typo in limiting offsets coalescing for http, leading to
whole files being downloaded instead of parts.
(Vincent Ladeuil, #165061)
* FTP server errors don't error in the error handling code.
(Robert Collins, #161240)
* Give a clearer message when a pull fails because the source needs
to be reconciled.
(Martin Pool, #164443)
* It is clearer when a plugin cannot be loaded because of its name, and a
suggestion for an acceptable name is given. (Daniel Watkins, #103023)
* Leave port as None in transport objects if user doesn't
specify a port in urls.
(vincent Ladeuil, #150860)
* Make sure Repository.fetch(self) is properly a no-op for all
Repository implementations. (John Arbash Meinel, #158333)
* Mark .bzr directories as "hidden" on Windows.
(Alexander Belchenko, #71147)
* ``merge --uncommitted`` can now operate on a single file.
(Aaron Bentley, Lukáš Lalinský, #136890)
* Obsolete packs are now cleaned up by pack and autopack operations.
(Robert Collins, #153789)
* Operations pulling data from a smart server where the underlying
repositories are not both annotated/both unannotated will now work.
(Robert Collins, #165304).
* Reconcile now shows progress bars. (Robert Collins, #159351)
* ``RemoteBranch`` was not initializing ``self._revision_id_to_revno_map``
properly. (John Arbash Meinel, #162486)
* Removing an already-removed file reports the file does not exist. (Daniel
Watkins, #152811)
* Rename on Windows is able to change filename case.
(Alexander Belchenko, #77740)
* Return error instead of a traceback for ``bzr log -r0``.
(Kent Gibson, #133751)
* Return error instead of a traceback when bzr is unable to create
symlink on some platforms (e.g. on Windows).
(Alexander Belchenko, workaround for #81689)
* Revert doesn't crash when restoring a single file from a deleted
directory. (Aaron Bentley)
* Stderr output via logging mechanism now goes through encoded wrapper
and no more uses utf-8, but terminal encoding instead. So all unicode
strings now should be readable in non-utf-8 terminal.
(Alexander Belchenko, #54173)
* The error message when ``move --after`` should be used makes how to do so
clearer. (Daniel Watkins, #85237)
* Unicode-safe output from ``bzr info``. The output will be encoded
using the terminal encoding and unrepresentable characters will be
replaced by '?'. (Lukáš Lalinský, #151844)
* Working trees are no longer created when pushing into a local no-trees
repo. (Daniel Watkins, #50582)
* Upgrade util/configobj to version 4.4.0.
(Vincent Ladeuil, #151208).
* Wrap medusa ftp test server as an FTPServer feature.
(Vincent Ladeuil, #157752)
API BREAKS:
* ``osutils.backup_file`` is deprecated. Actually it's not used in bzrlib
during very long time. (Alexander Belchenko)
* The return value of
``VersionedFile.iter_lines_added_or_present_in_versions`` has been
changed. Previously it was an iterator of lines, now it is an iterator of
(line, version_id) tuples. This change has been made to aid reconcile and
fetch operations. (Robert Collins)
* ``bzrlib.repository.get_versioned_file_checker`` is now private.
(Robert Collins)
* The Repository format registry default has been removed; it was previously
obsoleted by the bzrdir format default, which implies a default repository
format.
(Martin Pool)
INTERNALS:
* Added ``ContainerSerialiser`` and ``ContainerPushParser`` to
``bzrlib.pack``. These classes provide more convenient APIs for generating
and parsing containers from streams rather than from files. (Andrew
Bennetts)
* New module ``lru_cache`` providing a cache for use by tasks that need
semi-random access to large amounts of data. (John A Meinel)
* InventoryEntry.diff is now deprecated. Please use diff.DiffTree instead.
TESTING:
bzr 0.92 2007-11-05
-------------------
CHANGES:
* New uninstaller on Win32. (Alexander Belchenko)
bzr 0.92rc1 2007-10-29
----------------------
NOTES WHEN UPGRADING:
CHANGES:
* ``bzr`` now returns exit code 4 if an internal error occurred, and
3 if a normal error occurred. (Martin Pool)
* ``pull``, ``merge`` and ``push`` will no longer silently correct some
repository index errors that occured as a result of the Weave disk format.
Instead the ``reconcile`` command needs to be run to correct those
problems if they exist (and it has been able to fix most such problems
since bzr 0.8). Some new problems have been identified during this release
and you should run ``bzr check`` once on every repository to see if you
need to reconcile. If you cannot ``pull`` or ``merge`` from a remote
repository due to mismatched parent errors - a symptom of index errors -
you should simply take a full copy of that remote repository to a clean
directory outside any local repositories, then run reconcile on it, and
finally pull from it locally. (And naturally email the repositories owner
to ask them to upgrade and run reconcile).
(Robert Collins)
FEATURES:
* New ``knitpack-experimental`` repository format. This is interoperable with
the ``dirstate-tags`` format but uses a smarter storage design that greatly
speeds up many operations, both local and remote. This new format can be
used as an option to the ``init``, ``init-repository`` and ``upgrade``
commands. See http://doc.bazaar-vcs.org/0.92/developers/knitpack.html
for further details. (Robert Collins)
* For users of bzr-svn (and those testing the prototype subtree support) that
wish to try packs, a new ``knitpack-subtree-experimental`` format has also
been added. This is interoperable with the ``dirstate-subtrees`` format.
(Robert Collins)
* New ``reconfigure`` command. (Aaron Bentley)
* New ``revert --forget-merges`` command, which removes the record of a pending
merge without affecting the working tree contents. (Martin Pool)
* New ``bzr_remote_path`` configuration variable allows finer control of
remote bzr locations than BZR_REMOTE_PATH environment variable.
(Aaron Bentley)
* New ``launchpad-login`` command to tell Bazaar your Launchpad
user ID. This can then be used by other functions of the
Launchpad plugin. (James Henstridge)
PERFORMANCE:
* Commit in quiet mode is now slightly faster as the information to
output is no longer calculated. (Ian Clatworthy)
* Commit no longer checks for new text keys during insertion when the
revision id was deterministically unique. (Robert Collins)
* Committing a change which is not a merge and does not change the number of
files in the tree is faster by utilising the data about whether files are
changed to determine if the tree is unchanged rather than recalculating
it at the end of the commit process. (Robert Collins)
* Inventory serialisation no longer double-sha's the content.
(Robert Collins)
* Knit text reconstruction now avoids making copies of the lines list for
interim texts when building a single text. The new ``apply_delta`` method
on ``KnitContent`` aids this by allowing modification of the revision id
such objects represent. (Robert Collins)
* Pack indices are now partially parsed for specific key lookup using a
bisection approach. (Robert Collins)
* Partial commits are now approximately 40% faster by walking over the
unselected current tree more efficiently. (Robert Collins)
* XML inventory serialisation takes 20% less time while being stricter about
the contents. (Robert Collins)
* Graph ``heads()`` queries have been fixed to no longer access all history
unnecessarily. (Robert Collins)
IMPROVEMENTS:
* ``bzr+https://`` smart server across https now supported.
(John Ferlito, Martin Pool, #128456)
* Mutt is now a supported mail client; set ``mail_client=mutt`` in your
bazaar.conf and ``send`` will use mutt. (Keir Mierle)
* New option ``-c``/``--change`` for ``merge`` command for cherrypicking
changes from one revision. (Alexander Belchenko, #141368)
* Show encodings, locale and list of plugins in the traceback message.
(Martin Pool, #63894)
* Experimental directory formats can now be marked with
``experimental = True`` during registration. (Ian Clatworthy)
DOCUMENTATION:
* New *Bazaar in Five Minutes* guide. (Matthew Revell)
* The hooks reference documentation is now converted to html as expected.
(Ian Clatworthy)
BUG FIXES:
* Connection error reporting for the smart server has been fixed to
display a user friendly message instead of a traceback.
(Ian Clatworthy, #115601)
* Make sure to use ``O_BINARY`` when opening files to check their
sha1sum. (Alexander Belchenko, John Arbash Meinel, #153493)
* Fix a problem with Win32 handling of the executable bit.
(John Arbash Meinel, #149113)
* ``bzr+ssh://`` and ``sftp://`` URLs that do not specify ports explicitly
no longer assume that means port 22. This allows people using OpenSSH to
override the default port in their ``~/.ssh/config`` if they wish. This
fixes a bug introduced in bzr 0.91. (Andrew Bennetts, #146715)
* Commands reporting exceptions can now be profiled and still have their
data correctly dumped to a file. For example, a ``bzr commit`` with
no changes still reports the operation as pointless but doing so no
longer throws away the profiling data if this command is run with
``--lsprof-file callgrind.out.ci`` say. (Ian Clatworthy)
* Fallback to ftp when paramiko is not installed and sftp can't be used for
``tests/commands`` so that the test suite is still usable without
paramiko.
(Vincent Ladeuil, #59150)
* Fix commit ordering in corner case. (Aaron Bentley, #94975)
* Fix long standing bug in partial commit when there are renames
left in tree. (Robert Collins, #140419)
* Fix selftest semi-random noise during http related tests.
(Vincent Ladeuil, #140614)
* Fix typo in ftp.py making the reconnection fail on temporary errors.
(Vincent Ladeuil, #154259)
* Fix failing test by comparing real paths to cover the case where the TMPDIR
contains a symbolic link.
(Vincent Ladeuil, #141382).
* Fix log against smart server branches that don't support tags.
(James Westby, #140615)
* Fix pycurl http implementation by defining error codes from
pycurl instead of relying on an old curl definition.
(Vincent Ladeuil, #147530)
* Fix 'unprintable error' message when displaying BzrCheckError and
some other exceptions on Python 2.5.
(Martin Pool, #144633)
* Fix ``Inventory.copy()`` and add test for it. (Jelmer Vernooij)
* Handles default value for ListOption in cmd_commit.
(Vincent Ladeuil, #140432)
* HttpServer and FtpServer need to be closed properly or a listening socket
will remain opened.
(Vincent Ladeuil, #140055)
* Monitor the .bzr directory created in the top level test
directory to detect leaking tests.
(Vincent Ladeuil, #147986)
* The basename, not the full path, is now used when checking whether
the profiling dump file begins with ``callgrind.out`` or not. This
fixes a bug reported by Aaron Bentley on IRC. (Ian Clatworthy)
* Trivial fix for invoking command ``reconfigure`` without arguments.
(Rob Weir, #141629)
* ``WorkingTree.rename_one`` will now raise an error if normalisation of the
new path causes bzr to be unable to access the file. (Robert Collins)
* Correctly detect a NoSuchFile when using a filezilla server. (Gary van der
Merwe)
API BREAKS:
* ``bzrlib.index.GraphIndex`` now requires a size parameter to the
constructor, for enabling bisection searches. (Robert Collins)
* ``CommitBuilder.record_entry_contents`` now requires the root entry of a
tree be supplied to it, previously failing to do so would trigger a
deprecation warning. (Robert Collins)
* ``KnitVersionedFile.add*`` will no longer cache added records even when
enable_cache() has been called - the caching feature is now exclusively for
reading existing data. (Robert Collins)
* ``ReadOnlyLockError`` is deprecated; ``LockFailed`` is usually more
appropriate. (Martin Pool)
* Removed ``bzrlib.transport.TransportLogger`` - please see the new
``trace+`` transport instead. (Robert Collins)
* Removed previously deprecated varargs interface to ``TestCase.run_bzr`` and
deprecated methods ``TestCase.capture`` and ``TestCase.run_bzr_captured``.
(Martin Pool)
* Removed previous deprecated ``basis_knit`` parameter to the
``KnitVersionedFile`` constructor. (Robert Collins)
* Special purpose method ``TestCase.run_bzr_decode`` is moved to the test_non_ascii
class that needs it.
(Martin Pool)
* The class ``bzrlib.repofmt.knitrepo.KnitRepository3`` has been folded into
``KnitRepository`` by parameters to the constructor. (Robert Collins)
* The ``VersionedFile`` interface now allows content checks to be bypassed
by supplying check_content=False. This saves nearly 30% of the minimum
cost to store a version of a file. (Robert Collins)
* Tree's with bad state such as files with no length or sha will no longer
be silently accepted by the repository XML serialiser. To serialise
inventories without such data, pass working=True to write_inventory.
(Robert Collins)
* ``VersionedFile.fix_parents`` has been removed as a harmful API.
``VersionedFile.join`` will no longer accept different parents on either
side of a join - it will either ignore them, or error, depending on the
implementation. See notes when upgrading for more information.
(Robert Collins)
INTERNALS:
* ``bzrlib.transport.Transport.put_file`` now returns the number of bytes
put by the method call, to allow avoiding stat-after-write or
housekeeping in callers. (Robert Collins)
* ``bzrlib.xml_serializer.Serializer`` is now responsible for checking that
mandatory attributes are present on serialisation and deserialisation.
This fixes some holes in API usage and allows better separation between
physical storage and object serialisation. (Robert Collins)
* New class ``bzrlib.errors.InternalBzrError`` which is just a convenient
shorthand for deriving from BzrError and setting internal_error = True.
(Robert Collins)
* New method ``bzrlib.mutabletree.update_to_one_parent_via_delta`` for
moving the state of a parent tree to a new version via a delta rather than
a complete replacement tree. (Robert Collins)
* New method ``bzrlib.osutils.minimum_path_selection`` useful for removing
duplication from user input, when a user mentions both a path and an item
contained within that path. (Robert Collins)
* New method ``bzrlib.repository.Repository.is_write_locked`` useful for
determining if a repository is write locked. (Robert Collins)
* New method on ``bzrlib.tree.Tree`` ``path_content_summary`` provides a
tuple containing the key information about a path for commit processing
to complete. (Robert Collins)
* New method on xml serialisers, write_inventory_to_lines, which matches the
API used by knits for adding content. (Robert Collins)
* New module ``bzrlib.bisect_multi`` with generic multiple-bisection-at-once
logic, currently only available for byte-based lookup
(``bisect_multi_bytes``). (Robert Collins)
* New helper ``bzrlib.tuned_gzip.bytes_to_gzip`` which takes a byte string
and returns a gzipped version of the same. This is used to avoid a bunch
of api friction during adding of knit hunks. (Robert Collins)
* New parameter on ``bzrlib.transport.Transport.readv``
``adjust_for_latency`` which changes readv from returning strictly the
requested data to inserted return larger ranges and in forward read order
to reduce the effect of network latency. (Robert Collins)
* New parameter yield_parents on ``Inventory.iter_entries_by_dir`` which
causes the parents of a selected id to be returned recursively, so all the
paths from the root down to each element of selected_file_ids are
returned. (Robert Collins)
* Knit joining has been enhanced to support plain to annotated conversion
and annotated to plain conversion. (Ian Clatworthy)
* The CommitBuilder method ``record_entry_contents`` now returns summary
information about the effect of the commit on the repository. This tuple
contains an inventory delta item if the entry changed from the basis, and a
boolean indicating whether a new file graph node was recorded.
(Robert Collins)
* The python path used in the Makefile can now be overridden.
(Andrew Bennetts, Ian Clatworthy)
TESTING:
* New transport implementation ``trace+`` which is useful for testing,
logging activity taken to its _activity attribute. (Robert Collins)
* When running bzr commands within the test suite, internal exceptions are
not caught and reported in the usual way, but rather allowed to propagate
up and be visible to the test suite. A new API ``run_bzr_catch_user_errors``
makes this behavior available to other users.
(Martin Pool)
* New method ``TestCase.call_catch_warnings`` for testing methods that
raises a Python warning. (Martin Pool)
bzr 0.91 2007-09-26
-------------------
BUG FIXES:
* Print a warning instead of aborting the ``python setup.py install``
process if building of a C extension is not possible.
(Lukáš Lalinský, Alexander Belchenko)
* Fix commit ordering in corner case (Aaron Bentley, #94975)
* Fix ''bzr info bzr://host/'' and other operations on ''bzr://' URLs with
an implicit port. We were incorrectly raising PathNotChild due to
inconsistent treatment of the ''_port'' attribute on the Transport object.
(Andrew Bennetts, #133965)
* Make RemoteRepository.sprout cope gracefully with servers that don't
support the ``Repository.tarball`` request.
(Andrew Bennetts)
bzr 0.91rc2 2007-09-11
----------------------
* Replaced incorrect tarball for previous release; a debug statement was left
in bzrlib/remote.py.
bzr 0.91rc1 2007-09-11
----------------------
CHANGES:
* The default branch and repository format has changed to
``dirstate-tags``, so tag commands are active by default.
This format is compatible with Bazaar 0.15 and later.
This incidentally fixes bug #126141.
(Martin Pool)
* ``--quiet`` or ``-q`` is no longer a global option. If present, it
must now appear after the command name. Scripts doing things like
``bzr -q missing`` need to be rewritten as ``bzr missing -q``.
(Ian Clatworthy)
FEATURES:
* New option ``--author`` in ``bzr commit`` to specify the author of the
change, if it's different from the committer. ``bzr log`` and
``bzr annotate`` display the author instead of the committer.
(Lukáš Lalinský)
* In addition to global options and command specific options, a set of
standard options are now supported. Standard options are legal for
all commands. The initial set of standard options are:
* ``--help`` or ``-h`` - display help message
* ``--verbose`` or ``-v`` - display additional information
* ``--quiet`` or ``-q`` - only output warnings and errors.
Unlike global options, standard options can be used in aliases and
may have command-specific help. (Ian Clatworthy)
* Verbosity level processing has now been unified. If ``--verbose``
or ``-v`` is specified on the command line multiple times, the
verbosity level is made positive the first time then increased.
If ``--quiet`` or ``-q`` is specified on the command line
multiple times, the verbosity level is made negative the first
time then decreased. To get the default verbosity level of zero,
either specify none of the above , ``--no-verbose`` or ``--no-quiet``.
Note that most commands currently ignore the magnitude of the
verbosity level but do respect *quiet vs normal vs verbose* when
generating output. (Ian Clatworthy)
* ``Branch.hooks`` now supports ``pre_commit`` hook. The hook's signature
is documented in BranchHooks constructor. (Nam T. Nguyen, #102747)
* New ``Repository.stream_knit_data_for_revisions`` request added to the
network protocol for greatly reduced roundtrips when retrieving a set of
revisions. (Andrew Bennetts)
BUG FIXES:
* ``bzr plugins`` now lists the version number for each plugin in square
brackets after the path. (Robert Collins, #125421)
* Pushing, pulling and branching branches with subtree references was not
copying the subtree weave, preventing the file graph from being accessed
and causing errors in commits in clones. (Robert Collins)
* Suppress warning "integer argument expected, got float" from Paramiko,
which sometimes caused false test failures. (Martin Pool)
* Fix bug in bundle 4 that could cause attempts to write data to wrong
versionedfile. (Aaron Bentley)
* Diffs generated using "diff -p" no longer break the patch parser.
(Aaron Bentley)
* get_transport treats an empty possible_transports list the same as a non-
empty one. (Aaron Bentley)
* patch verification for merge directives is reactivated, and works with
CRLF and CR files. (Aaron Bentley)
* Accept ..\ as a path in revision specifiers. This fixes for example
"-r branch:..\other-branch" on Windows. (Lukáš Lalinský)
* ``BZR_PLUGIN_PATH`` may now contain trailing slashes.
(Blake Winton, #129299)
* man page no longer lists hidden options (#131667, Aaron Bentley)
* ``uncommit --help`` now explains the -r option adequately. (Daniel
Watkins, #106726)
* Error messages are now better formatted with parameters (such as
filenames) quoted when necessary. This avoids confusion when directory
names ending in a '.' at the end of messages were confused with a
full stop that may or not have been there. (Daniel Watkins, #129791)
* Fix ``status FILE -r X..Y``. (Lukáš Lalinský)
* If a particular command is an alias, ``help`` will show the alias
instead of claiming there is no help for said alias. (Daniel Watkins,
#133548)
* TreeTransform-based operations, like pull, merge, revert, and branch,
now roll back if they encounter an error. (Aaron Bentley, #67699)
* ``bzr commit`` now exits cleanly if a character unsupported by the
current encoding is used in the commit message. (Daniel Watkins,
#116143)
* bzr send uses default values for ranges when only half of an elipsis
is specified ("-r..5" or "-r5.."). (#61685, Aaron Bentley)
* Avoid trouble when Windows ssh calls itself 'plink' but no plink
binary is present. (Martin Albisetti, #107155)
* ``bzr remove`` should remove clean subtrees. Now it will remove (without
needing ``--force``) subtrees that contain no files with text changes or
modified files. With ``--force`` it removes the subtree regardless of
text changes or unknown files. Directories with renames in or out (but
not changed otherwise) will now be removed without needing ``--force``.
Unknown ignored files will be deleted without needing ``--force``.
(Marius Kruger, #111665)
* When two plugins conflict, the source of both the losing and now the
winning definition is shown. (Konstantin Mikhaylov, #5454)
* When committing to a branch, the location being committed to is
displayed. (Daniel Watkins, #52479)
* ``bzr --version`` takes care about encoding of stdout, especially
when output is redirected. (Alexander Belchenko, #131100)
* Prompt for an ftp password if none is provided.
(Vincent Ladeuil, #137044)
* Reuse bound branch associated transport to avoid multiple
connections.
(Vincent Ladeuil, #128076, #131396)
* Overwrite conflicting tags by ``push`` and ``pull`` if the
``--overwrite`` option is specified. (Lukáš Lalinský, #93947)
* In checkouts, tags are copied into the master branch when created,
changed or deleted, and are copied into the checkout when it is
updated. (Martin Pool, #93856, #93860)
* Print a warning instead of aborting the ``python setup.py install``
process if building of a C extension is not possible.
(Lukáš Lalinský, Alexander Belchenko)
IMPROVEMENTS:
* Add the option "--show-diff" to the commit command in order to display
the diff during the commit log creation. (Goffredo Baroncelli)
* ``pull`` and ``merge`` are much faster at installing bundle format 4.
(Aaron Bentley)
* ``pull -v`` no longer includes deltas, making it much faster.
(Aaron Bentley)
* ``send`` now sends the directive as an attachment by default.
(Aaron Bentley, Lukáš Lalinský, Alexander Belchenko)
* Documentation updates (Martin Albisetti)
* Help on debug flags is now included in ``help global-options``.
(Daniel Watkins, #124853)
* Parameters passed on the command line are checked to ensure they are
supported by the encoding in use. (Daniel Watkins)
* The compression used within the bzr repository has changed from zlib
level 9 to the zlib default level. This improves commit performance with
only a small increase in space used (and in some cases a reduction in
space). (Robert Collins)
* Initial commit no longer SHAs files twice and now reuses the path
rather than looking it up again, making it faster.
(Ian Clatworthy)
* New option ``-c``/``--change`` for ``diff`` and ``status`` to show
changes in one revision. (Lukáš Lalinský)
* If versioned files match a given ignore pattern, a warning is now
given. (Daniel Watkins, #48623)
* ``bzr status`` now has -S as a short name for --short and -V as a
short name for --versioned. These have been added to assist users
migrating from Subversion: ``bzr status -SV`` is now like
``svn status -q``. (Daniel Watkins, #115990)
* Added C implementation of ``PatienceSequenceMatcher``, which is about
10x faster than the Python version. This speeds up commands that
need file diffing, such as ``bzr commit`` or ``bzr diff``.
(Lukáš Lalinský)
* HACKING has been extended with a large section on core developer tasks.
(Ian Clatworthy)
* Add ``branches`` and ``standalone-trees`` as online help topics and
include them as Concepts within the User Reference.
(Paul Moore, Ian Clatworthy)
* ``check`` can detect versionedfile parent references that are
inconsistent with revision and inventory info, and ``reconcile`` can fix
them. These faulty references were generated by 0.8-era releases,
so repositories which were manipulated by old bzrs should be
checked, and possibly reconciled ASAP. (Aaron Bentley, Andrew Bennetts)
API BREAKS:
* ``Branch.append_revision`` is removed altogether; please use
``Branch.set_last_revision_info`` instead. (Martin Pool)
* CommitBuilder now advertises itself as requiring the root entry to be
supplied. This only affects foreign repository implementations which reuse
CommitBuilder directly and have changed record_entry_contents to require
that the root not be supplied. This should be precisely zero plugins
affected. (Robert Collins)
* The ``add_lines`` methods on ``VersionedFile`` implementations has changed
its return value to include the sha1 and length of the inserted text. This
allows the avoidance of double-sha1 calculations during commit.
(Robert Collins)
* ``Transport.should_cache`` has been removed. It was not called in the
previous release. (Martin Pool)
TESTING:
* Tests may now raise TestNotApplicable to indicate they shouldn't be
run in a particular scenario. (Martin Pool)
* New function multiply_tests_from_modules to give a simpler interface
to test parameterization. (Martin Pool, Robert Collins)
* ``Transport.should_cache`` has been removed. It was not called in the
previous release. (Martin Pool)
* NULL_REVISION is returned to indicate the null revision, not None.
(Aaron Bentley)
* Use UTF-8 encoded StringIO for log tests to avoid failures on
non-ASCII committer names. (Lukáš Lalinský)
INTERNALS:
* ``bzrlib.plugin.all_plugins`` has been deprecated in favour of
``bzrlib.plugin.plugins()`` which returns PlugIn objects that provide
useful functionality for determining the path of a plugin, its tests, and
its version information. (Robert Collins)
* Add the option user_encoding to the function 'show_diff_trees()'
in order to move the user encoding at the UI level. (Goffredo Baroncelli)
* Add the function make_commit_message_template_encoded() and the function
edit_commit_message_encoded() which handle encoded strings.
This is done in order to mix the commit messages (which is a unicode
string), and the diff which is a raw string. (Goffredo Baroncelli)
* CommitBuilder now defaults to using add_lines_with_ghosts, reducing
overhead on non-weave repositories which don't require all parents to be
present. (Robert Collins)
* Deprecated method ``find_previous_heads`` on
``bzrlib.inventory.InventoryEntry``. This has been superseded by the use
of ``parent_candidates`` and a separate heads check via the repository
API. (Robert Collins)
* New trace function ``mutter_callsite`` will print out a subset of the
stack to the log, which can be useful for gathering debug details.
(Robert Collins)
* ``bzrlib.pack.ContainerWriter`` now tracks how many records have been
added via a public attribute records_written. (Robert Collins)
* New method ``bzrlib.transport.Transport.get_recommended_page_size``.
This provides a hint to users of transports as to the reasonable
minimum data to read. In principle this can take latency and
bandwidth into account on a per-connection basis, but for now it
just has hard coded values based on the url. (e.g. http:// has a large
page size, file:// has a small one.) (Robert Collins)
* New method on ``bzrlib.transport.Transport`` ``open_write_stream`` allows
incremental addition of data to a file without requiring that all the
data be buffered in memory. (Robert Collins)
* New methods on ``bzrlib.knit.KnitVersionedFile``:
``get_data_stream(versions)``, ``insert_data_stream(stream)`` and
``get_format_signature()``. These provide some infrastructure for
efficiently streaming the knit data for a set of versions over the smart
protocol.
* Knits with no annotation cache still produce correct annotations.
(Aaron Bentley)
* Three new methods have been added to ``bzrlib.trace``:
``set_verbosity_level``, ``get_verbosity_level`` and ``is_verbose``.
``set_verbosity_level`` expects a numeric value: negative for quiet,
zero for normal, positive for verbose. The size of the number can be
used to determine just how quiet or verbose the application should be.
The existing ``be_quiet`` and ``is_quiet`` routines have been
integrated into this new scheme. (Ian Clatworthy)
* Options can now be delcared with a ``custom_callback`` parameter. If
set, this routine is called after the option is processed. This feature
is now used by the standard options ``verbose`` and ``quiet`` so that
setting one implicitly resets the other. (Ian Clatworthy)
* Rather than declaring a new option from scratch in order to provide
custom help, a centrally registered option can be decorated using the
new ``bzrlib.Option.custom_help`` routine. In particular, this routine
is useful when declaring better help for the ``verbose`` and ``quiet``
standard options as the base definition of these is now more complex
than before thanks to their use of a custom callback. (Ian Clatworthy)
* Tree._iter_changes(specific_file=[]) now iterates through no files,
instead of iterating through all files. None is used to iterate through
all files. (Aaron Bentley)
* WorkingTree.revert() now accepts None to revert all files. The use of
[] to revert all files is deprecated. (Aaron Bentley)
bzr 0.90 2007-08-28
-------------------
IMPROVEMENTS:
* Documentation is now organized into multiple directories with a level
added for different languages or locales. Added the Mini Tutorial
and Quick Start Summary (en) documents from the Wiki, improving the
content and readability of the former. Formatted NEWS as Release Notes
complete with a Table of Conents, one heading per release. Moved the
Developer Guide into the main document catalog and provided a link
from the developer document catalog back to the main one.
(Ian Clatworthy, Sabin Iacob, Alexander Belchenko)
API CHANGES:
* The static convenience method ``BzrDir.create_repository``
is deprecated. Callers should instead create a ``BzrDir`` instance
and call ``create_repository`` on that. (Martin Pool)
bzr 0.90rc1 2007-08-14
----------------------
BUGFIXES:
* ``bzr init`` should connect to the remote location one time only. We
have been connecting several times because we forget to pass around the
Transport object. This modifies ``BzrDir.create_branch_convenience``,
so that we can give it the Transport we already have.
(John Arbash Meinel, Vincent Ladeuil, #111702)
* Get rid of sftp connection cache (get rid of the FTP one too).
(Vincent Ladeuil, #43731)
* bzr branch {local|remote} remote don't try to create a working tree
anymore.
(Vincent Ladeuil, #112173)
* All identified multiple connections for a single bzr command have been
fixed. See bzrlib/tests/commands directory.
(Vincent Ladeuil)
* ``bzr rm`` now does not insist on ``--force`` to delete files that
have been renamed but not otherwise modified. (Marius Kruger,
#111664)
* ``bzr selftest --bench`` no longer emits deprecation warnings
(Lukáš Lalinský)
* ``bzr status`` now honours FILE parameters for conflict lists
(Aaron Bentley, #127606)
* ``bzr checkout`` now honours -r when reconstituting a working tree.
It also honours -r 0. (Aaron Bentley, #127708)
* ``bzr add *`` no more fails on Windows if working tree contains
non-ascii file names. (Kuno Meyer, #127361)
* allow ``easy_install bzr`` runs without fatal errors.
(Alexander Belchenko, #125521)
* Graph._filter_candidate_lca does not raise KeyError if a candidate
is eliminated just before it would normally be examined. (Aaron Bentley)
* SMTP connection failures produce a nice message, not a traceback.
(Aaron Bentley)
IMPROVEMENTS:
* Don't show "dots" progress indicators when run non-interactively, such
as from cron. (Martin Pool)
* ``info`` now formats locations more nicely and lists "submit" and
"public" branches (Aaron Bentley)
* New ``pack`` command that will trigger database compression within
the repository (Robert Collins)
* Implement ``_KnitIndex._load_data`` in a pyrex extension. The pyrex
version is approximately 2-3x faster at parsing a ``.kndx`` file.
Which yields a measurable improvement for commands which have to
read from the repository, such as a 1s => 0.75s improvement in
``bzr diff`` when there are changes to be shown. (John Arbash Meinel)
* Merge is now faster. Depending on the scenario, it can be more than 2x
faster. (Aaron Bentley)
* Give a clearer warning, and allow ``python setup.py install`` to
succeed even if pyrex is not available.
(John Arbash Meinel)
* ``DirState._read_dirblocks`` now has an optional Pyrex
implementation. This improves the speed of any command that has to
read the entire DirState. (``diff``, ``status``, etc, improve by
about 10%).
``bisect_dirblocks`` has also been improved, which helps all
``_get_entry`` type calls (whenever we are searching for a
particular entry in the in-memory DirState).
(John Arbash Meinel)
* ``bzr pull`` and ``bzr push`` no longer do a complete walk of the
branch revision history for ui display unless -v is supplied.
(Robert Collins)
* ``bzr log -rA..B`` output shifted to the left margin if the log only
contains merge revisions. (Kent Gibson)
* The ``plugins`` command is now public with improved help.
(Ian Clatworthy)
* New bundle and merge directive formats are faster to generate, and
* Annotate merge now works when there are local changes. (Aaron Bentley)
* Commit now only shows the progress in terms of directories instead of
entries. (Ian Clatworthy)
* Fix ``KnitRepository.get_revision_graph`` to not request the graph 2
times. This makes ``get_revision_graph`` 2x faster. (John Arbash
Meinel)
* Fix ``VersionedFile.get_graph()`` to avoid using
``set.difference_update(other)``, which has bad scaling when
``other`` is large. This improves ``VF.get_graph([version_id])`` for
a 12.5k graph from 2.9s down to 200ms. (John Arbash Meinel)
* The ``--lsprof-file`` option now generates output for KCacheGrind if
the file starts with ``callgrind.out``. This matches the default file
filtering done by KCacheGrind's Open Dialog. (Ian Clatworthy)
* Fix ``bzr update`` to avoid an unnecessary
``branch.get_master_branch`` call, which avoids 1 extra connection
to the remote server. (Partial fix for #128076, John Arbash Meinel)
* Log errors from the smart server in the trace file, to make debugging
test failures (and live failures!) easier. (Andrew Bennetts)
* The HTML version of the man page has been superceded by a more
comprehensive manual called the Bazaar User Reference. This manual
is completed generated from the online help topics. As part of this
change, limited reStructuredText is now explicitly supported in help
topics and command help with 'unnatural' markup being removed prior
to display by the online help or inclusion in the man page.
(Ian Clatworthy)
* HTML documentation now use files extension ``*.html``
(Alexander Belchenko)
* The cache of ignore definitions is now cleared in WorkingTree.unlock()
so that changes to .bzrignore aren't missed. (#129694, Daniel Watkins)
* ``bzr selftest --strict`` fails if there are any missing features or
expected test failures. (Daniel Watkins, #111914)
* Link to registration survey added to README. (Ian Clatworthy)
* Windows standalone installer show link to registration survey
when installation finished. (Alexander Belchenko)
LIBRARY API BREAKS:
* Deprecated dictionary ``bzrlib.option.SHORT_OPTIONS`` removed.
Options are now required to provide a help string and it must
comply with the style guide by being one or more sentences with an
initial capital and final period. (Martin Pool)
* KnitIndex.get_parents now returns tuples. (Robert Collins)
* Ancient unused ``Repository.text_store`` attribute has been removed.
(Robert Collins)
* The ``bzrlib.pack`` interface has changed to use tuples of bytestrings
rather than just bytestrings, making it easier to represent multiple
element names. As this interface was not used by any internal facilities
since it was introduced in 0.18 no API compatibility is being preserved.
The serialised form of these packs is identical with 0.18 when a single
element tuple is in use. (Robert Collins)
INTERNALS:
* merge now uses ``iter_changes`` to calculate changes, which makes room for
future performance increases. It is also more consistent with other
operations that perform comparisons, and reduces reliance on
Tree.inventory. (Aaron Bentley)
* Refactoring of transport classes connected to a remote server.
ConnectedTransport is a new class that serves as a basis for all
transports needing to connect to a remote server. transport.split_url
have been deprecated, use the static method on the object instead. URL
tests have been refactored too.
(Vincent Ladeuil)
* Better connection sharing for ConnectedTransport objects.
transport.get_transport() now accepts a 'possible_transports' parameter.
If a newly requested transport can share a connection with one of the
list, it will.
(Vincent Ladeuil)
* Most functions now accept ``bzrlib.revision.NULL_REVISION`` to indicate
the null revision, and consider using ``None`` for this purpose
deprecated. (Aaron Bentley)
* New ``index`` module with abstract index functionality. This will be
used during the planned changes in the repository layer. Currently the
index layer provides a graph aware immutable index, a builder for the
same index type to allow creating them, and finally a composer for
such indices to allow the use of many indices in a single query. The
index performance is not optimised, however the API is stable to allow
development on top of the index. (Robert Collins)
* ``bzrlib.dirstate.cmp_by_dirs`` can be used to compare two paths by
their directory sections. This is equivalent to comparing
``path.split('/')``, only without having to split the paths.
This has a Pyrex implementation available.
(John Arbash Meinel)
* New transport decorator 'unlistable+' which disables the list_dir
functionality for testing.
* Deprecated ``change_entry`` in transform.py. (Ian Clatworthy)
* RevisionTree.get_weave is now deprecated. Tree.plan_merge is now used
for performing annotate-merge. (Aaron Bentley)
* New EmailMessage class to create email messages. (Adeodato Simó)
* Unused functions on the private interface KnitIndex have been removed.
(Robert Collins)
* New ``knit.KnitGraphIndex`` which provides a ``KnitIndex`` layered on top
of a ``index.GraphIndex``. (Robert Collins)
* New ``knit.KnitVersionedFile.iter_parents`` method that allows querying
the parents of many knit nodes at once, reducing round trips to the
underlying index. (Robert Collins)
* Graph now has an is_ancestor method, various bits use it.
(Aaron Bentley)
* The ``-Dhpss`` flag now includes timing information. As well as
logging when a new connection is opened. (John Arbash Meinel)
* ``bzrlib.pack.ContainerWriter`` now returns an offset, length tuple to
callers when inserting data, allowing generation of readv style access
during pack creation, without needing a separate pass across the output
pack to gather such details. (Robert Collins)
* ``bzrlib.pack.make_readv_reader`` allows readv based access to pack
files that are stored on a transport. (Robert Collins)
* New ``Repository.has_same_location`` method that reports if two
repository objects refer to the same repository (although with some risk
of false negatives). (Andrew Bennetts)
* InterTree.compare now passes require_versioned on correctly.
(Marius Kruger)
* New methods on Repository - ``start_write_group``,
``commit_write_group``, ``abort_write_group`` and ``is_in_write_group`` -
which provide a clean hook point for transactional Repositories - ones
where all the data for a fetch or commit needs to be made atomically
available in one step. This allows the write lock to remain while making
a series of data insertions. (e.g. data conversion). (Robert Collins)
* In ``bzrlib.knit`` the internal interface has been altered to use
3-tuples (index, pos, length) rather than two-tuples (pos, length) to
describe where data in a knit is, allowing knits to be split into
many files. (Robert Collins)
* ``bzrlib.knit._KnitData`` split into cache management and physical access
with two access classes - ``_PackAccess`` and ``_KnitAccess`` defined.
The former provides access into a .pack file, and the latter provides the
current production repository form of .knit files. (Robert Collins)
TESTING:
* Remove selftest ``--clean-output``, ``--numbered-dirs`` and
``--keep-output`` options, which are obsolete now that tests
are done within directories in $TMPDIR. (Martin Pool)
* The SSH_AUTH_SOCK environment variable is now reset to avoid
interaction with any running ssh agents. (Jelmer Vernooij, #125955)
* run_bzr_subprocess handles parameters the same way as run_bzr:
either a string or a list of strings should be passed as the first
parameter. Varargs-style parameters are deprecated. (Aaron Bentley)
bzr 0.18 2007-07-17
--------------------
BUGFIXES:
* Fix 'bzr add' crash under Win32 (Kuno Meyer)
bzr 0.18rc1 2007-07-10
-----------------------
BUGFIXES:
* Do not suppress pipe errors, etc. in non-display commands
(Alexander Belchenko, #87178)
* Display a useful error message when the user requests to annotate
a file that is not present in the specified revision.
(James Westby, #122656)
* Commands that use status flags now have a reference to 'help
status-flags'. (Daniel Watkins, #113436)
* Work around python-2.4.1 inhability to correctly parse the
authentication header.
(Vincent Ladeuil, #121889)
* Use exact encoding for merge directives. (Adeodato Simó, #120591)
* Fix tempfile permissions error in smart server tar bundling under
Windows. (Martin _, #119330)
* Fix detection of directory entries in the inventory. (James Westby)
* Fix handling of http code 400: Bad Request When issuing too many ranges.
(Vincent Ladeuil, #115209)
* Issue a CONNECT request when connecting to an https server
via a proxy to enable SSL tunneling.
(Vincent Ladeuil, #120678)
* Fix ``bzr log -r`` to support selecting merge revisions, both
individually and as part of revision ranges.
(Kent Gibson, #4663)
* Don't leave cruft behind when failing to acquire a lockdir.
(Martin Pool, #109169)
* Don't use the '-f' strace option during tests.
(Vincent Ladeuil, #102019).
* Warn when setting ``push_location`` to a value that will be masked by
locations.conf. (Aaron Bentley, #122286)
* Fix commit ordering in corner case (Aaron Bentley, #94975)
* Make annotate behave in a non-ASCII world (Adeodato Simó).
IMPROVEMENTS:
* The --lsprof-file option now dumps a text rendering of the profiling
information if the filename ends in ".txt". It will also convert the
profiling information to a format suitable for KCacheGrind if the
output filename ends in ".callgrind". Fixes to the lsprofcalltree
conversion process by Jean Paul Calderone and Itamar were also merged.
See http://ddaa.net/blog/python/lsprof-calltree. (Ian Clatworthy)
* ``info`` now defaults to non-verbose mode, displaying only paths and
abbreviated format info. ``info -v`` displays all the information
formerly displayed by ``info``. (Aaron Bentley, Adeodato Simó)
* ``bzr missing`` now has better option names ``--this`` and ``--other``.
(Elliot Murphy)
* The internal ``weave-list`` command has become ``versionedfile-list``,
and now lists knits as well as weaves. (Aaron Bentley)
* Automatic merge base selection uses a faster algorithm that chooses
better bases in criss-cross merge situations (Aaron Bentley)
* Progress reporting in ``commit`` has been improved. The various logical
stages are now reported on as follows, namely:
* Collecting changes [Entry x/y] - Stage n/m
* Saving data locally - Stage n/m
* Uploading data to master branch - Stage n/m
* Updating the working tree - Stage n/m
* Running post commit hooks - Stage n/m
If there is no master branch, the 3rd stage is omitted and the total
number of stages is adjusted accordingly.
Each hook that is run after commit is listed with a name (as hooks
can be slow it is useful feedback).
(Ian Clatworthy, Robert Collins)
* Various operations that are now faster due to avoiding unnecessary
topological sorts. (Aaron Bentley)
* Make merge directives robust against broken bundles. (Aaron Bentley)
* The lsprof filename note is emitted via trace.note(), not standard
output. (Aaron Bentley)
* ``bzrlib`` now exports explicit API compatibility information to assist
library users and plugins. See the ``bzrlib.api`` module for details.
(Robert Collins)
* Remove unnecessary lock probes when acquiring a lockdir.
(Martin Pool)
* ``bzr --version`` now shows the location of the bzr log file, which
is especially useful on Windows. (Martin Pool)
* -D now supports hooks to get debug tracing of hooks (though its currently
minimal in nature). (Robert Collins)
* Long log format reports deltas on merge revisions.
(John Arbash Meinel, Kent Gibson)
* Make initial push over ftp more resilient. (John Arbash Meinel)
* Print a summary of changes for update just like pull does.
(Daniel Watkins, #113990)
* Add a -Dhpss option to trace smart protocol requests and responses.
(Andrew Bennetts)
LIBRARY API BREAKS:
* Testing cleanups -
``bzrlib.repository.RepositoryTestProviderAdapter`` has been moved
to ``bzrlib.tests.repository_implementations``;
``bzrlib.repository.InterRepositoryTestProviderAdapter`` has been moved
to ``bzrlib.tests.interrepository_implementations``;
``bzrlib.transport.TransportTestProviderAdapter`` has moved to
``bzrlib.tests.test_transport_implementations``.
``bzrlib.branch.BranchTestProviderAdapter`` has moved to
``bzrlib.tests.branch_implementations``.
``bzrlib.bzrdir.BzrDirTestProviderAdapter`` has moved to
``bzrlib.tests.bzrdir_implementations``.
``bzrlib.versionedfile.InterVersionedFileTestProviderAdapter`` has moved
to ``bzrlib.tests.interversionedfile_implementations``.
``bzrlib.store.revision.RevisionStoreTestProviderAdapter`` has moved to
``bzrlib.tests.revisionstore_implementations``.
``bzrlib.workingtree.WorkingTreeTestProviderAdapter`` has moved to
``bzrlib.tests.workingtree_implementations``.
These changes are an API break in the testing infrastructure only.
(Robert Collins)
* Relocate TestCaseWithRepository to be more central. (Robert Collins)
* ``bzrlib.add.smart_add_tree`` will no longer perform glob expansion on
win32. Callers of the function should do this and use the new
``MutableTree.smart_add`` method instead. (Robert Collins)
* ``bzrlib.add.glob_expand_for_win32`` is now
``bzrlib.win32utils.glob_expand``. (Robert Collins)
* ``bzrlib.add.FastPath`` is now private and moved to
``bzrlib.mutabletree._FastPath``. (Robert Collins, Martin Pool)
* ``LockDir.wait`` removed. (Martin Pool)
* The ``SmartServer`` hooks API has changed for the ``server_started`` and
``server_stopped`` hooks. The first parameter is now an iterable of
backing URLs rather than a single URL. This is to reflect that many
URLs may map to the external URL of the server. E.g. the server interally
may have a chrooted URL but also the local file:// URL will be at the
same location. (Robert Collins)
INTERNALS:
* New SMTPConnection class to unify email handling. (Adeodato Simó)
* Fix documentation of BzrError. (Adeodato Simó)
* Make BzrBadParameter an internal error. (Adeodato Simó)
* Remove use of 'assert False' to raise an exception unconditionally.
(Martin Pool)
* Give a cleaner error when failing to decode knit index entry.
(Martin Pool)
* TreeConfig would mistakenly search the top level when asked for options
from a section. It now respects the section argument and only
searches the specified section. (James Westby)
* Improve ``make api-docs`` output. (John Arbash Meinel)
* Use os.lstat rather than os.stat for osutils.make_readonly and
osutils.make_writeable. This makes the difftools plugin more
robust when dangling symlinks are found. (Elliot Murphy)
* New ``-Dlock`` option to log (to ~/.bzr.log) information on when
lockdirs are taken or released. (Martin Pool)
* ``bzrlib`` Hooks are now nameable using ``Hooks.name_hook``. This
allows a nicer UI when hooks are running as the current hook can
be displayed. (Robert Collins)
* ``Transport.get`` has had its interface made more clear for ease of use.
Retrieval of a directory must now fail with either 'PathError' at open
time, or raise 'ReadError' on a read. (Robert Collins)
* New method ``_maybe_expand_globs`` on the ``Command`` class for
dealing with unexpanded glob lists - e.g. on the win32 platform. This
was moved from ``bzrlib.add._prepare_file_list``. (Robert Collins)
* ``bzrlib.add.smart_add`` and ``bzrlib.add.smart_add_tree`` are now
deprecated in favour of ``MutableTree.smart_add``. (Robert Collins,
Martin Pool)
* New method ``external_url`` on Transport for obtaining the url to
hand to external processes. (Robert Collins)
* Teach windows installers to build pyrex/C extensions.
(Alexander Belchenko)
TESTING:
* Removed the ``--keep-output`` option from selftest and clean up test
directories as they're used. This reduces the IO load from
running the test suite and cuts the time by about half.
(Andrew Bennetts, Martin Pool)
* Add scenarios as a public attribute on the TestAdapter classes to allow
modification of the generated scenarios before adaption and easier
testing. (Robert Collins)
* New testing support class ``TestScenarioApplier`` which multiplies
out a single teste by a list of supplied scenarios. (RobertCollins)
* Setting ``repository_to_test_repository`` on a repository_implementations
test will cause it to be called during repository creation, allowing the
testing of repository classes which are not based around the Format
concept. For example a repository adapter can be tested in this manner,
by altering the repository scenarios to include a scenario that sets this
attribute during the test parameterisation in
``bzrlib.tests.repository.repository_implementations``. (Robert Collins)
* Clean up many of the APIs for blackbox testing of Bazaar. The standard
interface is now self.run_bzr. The command to run can be passed as
either a list of parameters, a string containing the command line, or
(deprecated) varargs parameters. (Martin Pool)
* The base TestCase now isolates tests from -D parameters by clearing
``debug.debug_flags`` and restores it afterwards. (Robert Collins)
* Add a relpath parameter to get_transport methods in test framework to
avoid useless cloning.
(Vincent Ladeuil, #110448)
bzr 0.17 2007-06-18
--------------------
BUGFIXES:
* Fix crash of commit due to wrong lookup of filesystem encoding.
(Colin Watson, #120647)
* Revert logging just to stderr in commit as broke unicode filenames.
(Aaron Bentley, Ian Clatworthy, #120930)
bzr 0.17rc1 2007-06-12
-----------------------
NOTES WHEN UPGRADING:
* The kind() and is_executable() APIs on the WorkingTree interface no
longer implicitly (read) locks and unlocks the tree. This *might*
impact some plug-ins and tools using this part of the API. If you find
an issue that may be caused by this change, please let us know,
particularly the plug-in/tool maintainer. If encountered, the API
fix is to surround kind() and is_executable() calls with lock_read()
and unlock() like so::
work_tree.lock_read()
try:
kind = work_tree.kind(...)
finally:
work_tree.unlock()
INTERNALS:
* Rework of LogFormatter API to provide beginning/end of log hooks and to
encapsulate the details of the revision to be logged in a LogRevision
object.
In long log formats, merge revision ids are only shown when --show-ids
is specified, and are labelled "revision-id:", as per mainline
revisions, instead of "merged:". (Kent Gibson)
* New ``BranchBuilder`` API which allows the construction of particular
histories quickly. Useful for testing and potentially other applications
too. (Robert Collins)
IMPROVEMENTS:
* There are two new help topics, working-trees and repositories that
attempt to explain these concepts. (James Westby, John Arbash Meinel,
Aaron Bentley)
* Added ``bzr log --limit`` to report a limited number of revisions.
(Kent Gibson, #3659)
* Revert does not try to preserve file contents that were originally
produced by reverting to a historical revision. (Aaron Bentley)
* ``bzr log --short`` now includes ``[merge]`` for revisions which
have more than one parent. This is a small improvement to help
understanding what changes have occurred
(John Arbash Meinel, #83887)
* TreeTransform avoids many renames when contructing large trees,
improving speed. 3.25x speedups have been observed for construction of
kernel-sized-trees, and checkouts are 1.28x faster. (Aaron Bentley)
* Commit on large trees is now faster. In my environment, a commit of
a small change to the Mozilla tree (55k files) has dropped from
66 seconds to 32 seconds. For a small tree of 600 files, commit of a
small change is 33% faster. (Ian Clatworthy)
* New --create-prefix option to bzr init, like for push. (Daniel Watkins,
#56322)
BUGFIXES:
* ``bzr push`` should only connect to the remote location one time.
We have been connecting 3 times because we forget to pass around
the Transport object. This adds ``BzrDir.clone_on_transport()``, so
that we can pass in the Transport that we already have.
(John Arbash Meinel, #75721)
* ``DirState.set_state_from_inventory()`` needs to properly order
based on split paths, not just string paths.
(John Arbash Meinel, #115947)
* Let TestUIFactoy encode the password prompt with its own stdout.
(Vincent Ladeuil, #110204)
* pycurl should take use the range header that takes the range hint
into account.
(Vincent Ladeuil, #112719)
* WorkingTree4.get_file_sha1 no longer raises an exception when invoked
on a missing file. (Aaron Bentley, #118186)
* WorkingTree.remove works correctly with tree references, and when pwd is
not the tree root. (Aaron Bentley)
* Merge no longer fails when a file is renamed in one tree and deleted
in the other. (Aaron Bentley, #110279)
* ``revision-info`` now accepts dotted revnos, doesn't require a tree,
and defaults to the last revision (Matthew Fuller, #90048)
* Tests no longer fail when BZR_REMOTE_PATH is set in the environment.
(Daniel Watkins, #111958)
* ``bzr branch -r revid:foo`` can be used to branch any revision in
your repository. (Previously Branch6 only supported revisions in your
mainline). (John Arbash Meinel, #115343)
bzr 0.16 2007-05-07
--------------------
BUGFIXES:
* Handle when you have 2 directories with similar names, but one has a
hyphen. (``'abc'`` versus ``'abc-2'``). The WT4._iter_changes
iterator was using direct comparison and ``'abc/a'`` sorts after
``'abc-2'``, but ``('abc', 'a')`` sorts before ``('abc-2',)``.
(John Arbash Meinel, #111227)
* Handle when someone renames a file on disk without telling bzr.
Previously we would report the first file as missing, but not show
the new unknown file. (John Arbash Meinel, #111288)
* Avoid error when running hooks after pulling into or pushing from
a branch bound to a smartserver branch. (Martin Pool, #111968)
IMPROVEMENTS:
* Move developer documentation to doc/developers/. This reduces clutter in
the root of the source tree and allows HACKING to be split into multiple
files. (Robert Collins, Alexander Belchenko)
* Clean up the ``WorkingTree4._iter_changes()`` internal loops as well as
``DirState.update_entry()``. This optimizes the core logic for ``bzr
diff`` and ``bzr status`` significantly improving the speed of
both. (John Arbash Meinel)
bzr 0.16rc2 2007-04-30
-----------------------
BUGFIXES:
* Handle the case when you delete a file, and then rename another file
on top of it. Also handle the case of ``bzr rm --keep foo``. ``bzr
status`` should show the removed file and an unknown file in its
place. (John Arbash Meinel, #109993)
* Bundles properly read and write revision properties that have an
empty value. And when the value is not ASCII.
(John Arbash Meinel, #109613)
* Fix the bzr commit message to be in text mode.
(Alexander Belchenko, #110901)
* Also handle when you rename a file and create a file where it used
to be. (John Arbash Meinel, #110256)
* ``WorkingTree4._iter_changes`` should not descend into unversioned
directories. (John Arbash Meinel, #110399)
bzr 0.16rc1 2007-04-26
-----------------------
NOTES WHEN UPGRADING:
* ``bzr remove`` and ``bzr rm`` will now remove the working file, if
it could be recovered again.
This has been done for consistency with svn and the unix rm command.
The old ``remove`` behaviour has been retained in the new option
``bzr remove --keep``, which will just stop versioning the file,
but not delete it.
``bzr remove --force`` have been added which will always delete the
files.
``bzr remove`` is also more verbose.
(Marius Kruger, #82602)
IMPROVEMENTS:
* Merge directives can now be supplied as input to `merge` and `pull`,
like bundles can. (Aaron Bentley)
* Sending the SIGQUIT signal to bzr, which can be done on Unix by
pressing Control-Backslash, drops bzr into a debugger. Type ``'c'``
to continue. This can be disabled by setting the environment variable
``BZR_SIGQUIT_PDB=0``. (Martin Pool)
* selftest now supports --list-only to list tests instead of running
them. (Ian Clatworthy)
* selftest now supports --exclude PATTERN (or -x PATTERN) to exclude
tests with names that match that regular expression.
(Ian Clatworthy, #102679)
* selftest now supports --randomize SEED to run tests in a random order.
SEED is typically the value 'now' meaning 'use the current time'.
(Ian Clatworthy, #102686)
* New option ``--fixes`` to commit, which stores bug fixing annotations as
revision properties. Built-in support for Launchpad, Debian, Trac and
Bugzilla bug trackers. (Jonathan Lange, James Henstridge, Robert Collins)
* New API, ``bzrlib.bugtracker.tracker_registry``, for adding support for
other bug trackers to ``fixes``. (Jonathan Lange, James Henstridge,
Robert Collins)
* ``selftest`` has new short options ``-f`` and ``-1``. (Martin
Pool)
* ``bzrlib.tsort.MergeSorter`` optimizations. Change the inner loop
into using local variables instead of going through ``self._var``.
Improves the time to ``merge_sort`` a 10k revision graph by
approximately 40% (~700->400ms). (John Arbash Meinel)
* ``make docs`` now creates a man page at ``man1/bzr.1`` fixing bug 107388.
(Robert Collins)
* ``bzr help`` now provides cross references to other help topics using
the _see_also facility on command classes. Likewise the bzr_man
documentation, and the bzr.1 man page also include this information.
(Robert Collins)
* Tags are now included in logs, that use the long log formatter.
(Erik BÃ¥gfors, Alexander Belchenko)
* ``bzr help`` provides a clearer message when a help topic cannot be
found. (Robert Collins, #107656)
* ``bzr help`` now accepts optional prefixes for command help. The help
for all commands can now be found at ``bzr help commands/COMMANDNAME``
as well as ``bzr help COMMANDNAME`` (which only works for commands
where the name is not the same as a more general help topic).
(Robert Collins)
* ``bzr help PLUGINNAME`` will now return the module docstring from the
plugin PLUGINNAME. (Robert Collins, #50408)
* New help topic ``urlspec`` which lists the availables transports.
(Goffredo Baroncelli)
* doc/server.txt updated to document the default bzr:// port
and also update the blurb about the hpss' current status.
(Robert Collins, #107125).
* ``bzr serve`` now listens on interface 0.0.0.0 by default, making it
serve out to the local LAN (and anyone in the world that can reach the
machine running ``bzr serve``. (Robert Collins, #98918)
* A new smart server protocol version has been added. It prefixes requests
and responses with an explicit version identifier so that future protocol
revisions can be dealt with gracefully. (Andrew Bennetts, Robert Collins)
* The bzr protocol version 2 indicates success or failure in every response
without depending on particular commands encoding that consistently,
allowing future client refactorings to be much more robust about error
handling. (Robert Collins, Martin Pool, Andrew Bennetts)
* The smart protocol over HTTP client has been changed to always post to the
same ``.bzr/smart`` URL under the original location when it can. This allows
HTTP servers to only have to pass URLs ending in .bzr/smart to the smart
server handler, and not arbitrary ``.bzr/*/smart`` URLs. (Andrew Bennetts)
* digest authentication is now supported for proxies and HTTP by the urllib
based http implementation. Tested against Apache 2.0.55 and Squid
2.6.5. Basic and digest authentication are handled coherently for HTTP
and proxy: if the user is provided in the url (bzr command line for HTTP,
proxy environment variables for proxies), the password is prompted for
(only once). If the password is provided, it is taken into account. Once
the first authentication is successful, all further authentication
roundtrips are avoided by preventively setting the right authentication
header(s).
(Vincent Ladeuil).
INTERNALS:
* bzrlib API compatability with 0.8 has been dropped, cleaning up some
code paths. (Robert Collins)
* Change the format of chroot urls so that they can be safely manipulated
by generic url utilities without causing the resulting urls to have
escaped the chroot. A side effect of this is that creating a chroot
requires an explicit action using a ChrootServer.
(Robert Collins, Andrew Bennetts)
* Deprecate ``Branch.get_root_id()`` because branches don't have root ids,
rather than fixing bug #96847. (Aaron Bentley)
* ``WorkingTree.apply_inventory_delta`` provides a better alternative to
``WorkingTree._write_inventory``. (Aaron Bentley)
* Convenience method ``TestCase.expectFailure`` ensures that known failures
do not silently pass. (Aaron Bentley)
* ``Transport.local_abspath`` now raises ``NotLocalUrl`` rather than
``TransportNotPossible``. (Martin Pool, Ian Clatworthy)
* New SmartServer hooks facility. There are two initial hooks documented
in ``bzrlib.transport.smart.SmartServerHooks``. The two initial hooks allow
plugins to execute code upon server startup and shutdown.
(Robert Collins).
* SmartServer in standalone mode will now close its listening socket
when it stops, rather than waiting for garbage collection. This primarily
fixes test suite hangs when a test tries to connect to a shutdown server.
It may also help improve behaviour when dealing with a server running
on a specific port (rather than dynamically assigned ports).
(Robert Collins)
* Move most SmartServer code into a new package, bzrlib/smart.
bzrlib/transport/remote.py contains just the Transport classes that used
to be in bzrlib/transport/smart.py. (Andrew Bennetts)
* urllib http implementation avoid roundtrips associated with
401 (and 407) errors once the authentication succeeds.
(Vincent Ladeuil).
* urlib http now supports querying the user for a proxy password if
needed. Realm is shown in the prompt for both HTTP and proxy
authentication when the user is required to type a password.
(Vincent Ladeuil).
* Renamed SmartTransport (and subclasses like SmartTCPTransport) to
RemoteTransport (and subclasses to RemoteTCPTransport, etc). This is more
consistent with its new home in ``bzrlib/transport/remote.py``, and because
it's not really a "smart" transport, just one that does file operations
via remote procedure calls. (Andrew Bennetts)
* The ``lock_write`` method of ``LockableFiles``, ``Repository`` and
``Branch`` now accept a ``token`` keyword argument, so that separate
instances of those objects can share a lock if it has the right token.
(Andrew Bennetts, Robert Collins)
* New method ``get_branch_reference`` on ``BzrDir`` allows the detection of
branch references - which the smart server component needs.
* The Repository API ``make_working_trees`` is now permitted to return
False when ``set_make_working_trees`` is not implemented - previously
an unimplemented ``set_make_working_trees`` implied the result True
from ``make_working_trees``. This has been changed to accomodate the
smart server, where it does not make sense (at this point) to ever
make working trees by default. (Robert Collins)
* Command objects can now declare related help topics by having _see_also
set to a list of related topic. (Robert Collins)
* ``bzrlib.help`` now delegates to the Command class for Command specific
help. (Robert Collins)
* New class ``TransportListRegistry``, derived from the Registry class, which
simplifies tracking the available Transports. (Goffredo Baroncelli)
* New function ``Branch.get_revision_id_to_revno_map`` which will
return a dictionary mapping revision ids to dotted revnos. Since
dotted revnos are defined in the context of the branch tip, it makes
sense to generate them from a ``Branch`` object.
(John Arbash Meinel)
* Fix the 'Unprintable error' message display to use the repr of the
exception that prevented printing the error because the str value
for it is often not useful in debugging (e.g. KeyError('foo') has a
str() of 'foo' but a repr of 'KeyError('foo')' which is much more
useful. (Robert Collins)
* ``urlutils.normalize_url`` now unescapes unreserved characters, such as "~".
(Andrew Bennetts)
BUGFIXES:
* Don't fail bundle selftest if email has 'two' embedded.
(Ian Clatworthy, #98510)
* Remove ``--verbose`` from ``bzr bundle``. It didn't work anyway.
(Robert Widhopf-Fenk, #98591)
* Remove ``--basis`` from the checkout/branch commands - it didn't work
properly and is no longer beneficial.
(Robert Collins, #53675, #43486)
* Don't produce encoding error when adding duplicate files.
(Aaron Bentley)
* Fix ``bzr log <file>`` so it only logs the revisions that changed
the file, and does it faster.
(Kent Gibson, John Arbash Meinel, #51980, #69477)
* Fix ``InterDirstateTre._iter_changes`` to handle when we come across
an empty versioned directory, which now has files in it.
(John Arbash Meinel, #104257)
* Teach ``common_ancestor`` to shortcut when the tip of one branch is
inside the ancestry of the other. Saves a lot of graph processing
(with an ancestry of 16k revisions, ``bzr merge ../already-merged``
changes from 2m10s to 13s). (John Arbash Meinel, #103757)
* Fix ``show_diff_trees`` to handle the case when a file is modified,
and the containing directory is renamed. (The file path is different
in this versus base, but it isn't marked as a rename).
(John Arbash Meinel, #103870)
* FTP now works even when the FTP server does not support atomic rename.
(Aaron Bentley, #89436)
* Correct handling in bundles and merge directives of timezones with
that are not an integer number of hours offset from UTC. Always
represent the epoch time in UTC to avoid problems with formatting
earlier times on win32. (Martin Pool, Alexander Belchenko, John
Arbash Meinel)
* Typo in the help for ``register-branch`` fixed. (Robert Collins, #96770)
* "dirstate" and "dirstate-tags" formats now produce branches compatible
with old versions of bzr. (Aaron Bentley, #107168))
* Handle moving a directory when children have been added, removed,
and renamed. (John Arbash Meinel, #105479)
* Don't preventively use basic authentication for proxy before receiving a
407 error. Otherwise people willing to use other authentication schemes
may expose their password in the clear (or nearly). This add one
roundtrip in case basic authentication should be used, but plug the
security hole.
(Vincent Ladeuil)
* Handle http and proxy digest authentication.
(Vincent Ladeuil, #94034).
TESTING:
* Added ``bzrlib.strace.strace`` which will strace a single callable and
return a StraceResult object which contains just the syscalls involved
in running it. (Robert Collins)
* New test method ``reduceLockdirTimeout`` to drop the default (ui-centric)
default time down to one suitable for tests. (Andrew Bennetts)
* Add new ``vfs_transport_factory`` attribute on tests which provides the
common vfs backing for both the readonly and readwrite transports.
This allows the RemoteObject tests to back onto local disk or memory,
and use the existing ``transport_server`` attribute all tests know about
to be the smart server transport. This in turn allows tests to
differentiate between 'transport to access the branch', and
'transport which is a VFS' - which matters in Remote* tests.
(Robert Collins, Andrew Bennetts)
* The ``make_branch_and_tree`` method for tests will now create a
lightweight checkout for the tree if the ``vfs_transport_factory`` is not
a LocalURLServer. (Robert Collins, Andrew Bennetts)
* Branch implementation tests have been audited to ensure that all urls
passed to Branch APIs use proper urls, except when local-disk paths
are intended. This is so that tests correctly access the test transport
which is often not equivalent to local disk in Remote* tests. As part
of this many tests were adjusted to remove dependencies on local disk
access.
(Robert Collins, Andrew Bennetts)
* Mark bzrlib.tests and bzrlib.tests.TestUtil as providing assertFOO helper
functions by adding a ``__unittest`` global attribute. (Robert Collins,
Andrew Bennetts, Martin Pool, Jonathan Lange)
* Refactored proxy and authentication handling to simplify the
implementation of new auth schemes for both http and proxy.
(Vincent Ladeuil)
bzr 0.15 2007-04-01
-------------------
BUGFIXES:
* Handle incompatible repositories as a user issue when fetching.
(Aaron Bentley)
* Don't give a recommendation to upgrade when branching or
checking out a branch that contains an old-format working tree.
(Martin Pool)
bzr 0.15rc3 2007-03-26
-----------------------
CHANGES:
* A warning is now displayed when opening working trees in older
formats, to encourage people to upgrade to WorkingTreeFormat4.
(Martin Pool)
IMPROVEMENTS:
* HTTP redirections are now taken into account when a branch (or a
bundle) is accessed for the first time. A message is issued at each
redirection to inform the user. In the past, http redirections were
silently followed for each request which significantly degraded the
performances. The http redirections are not followed anymore by
default, instead a RedirectRequested exception is raised. For bzrlib
users needing to follow http redirections anyway,
``bzrlib.transport.do_catching_redirections`` provide an easy transition
path. (vila)
INTERNALS:
* Added ``ReadLock.temporary_write_lock()`` to allow upgrading an OS read
lock to an OS write lock. Linux can do this without unlocking, Win32
needs to unlock in between. (John Arbash Meinel)
* New parameter ``recommend_upgrade`` to ``BzrDir.open_workingtree``
to silence (when false) warnings about opening old formats.
(Martin Pool)
* Fix minor performance regression with bzr-0.15 on pre-dirstate
trees. (We were reading the working inventory too many times).
(John Arbash Meinel)
* Remove ``Branch.get_transaction()`` in favour of a simple cache of
``revision_history``. Branch subclasses should override
``_gen_revision_history`` rather than ``revision_history`` to make use of
this cache, and call ``_clear_revision_history_cache`` and
``_cache_revision_history`` at appropriate times. (Andrew Bennetts)
BUGFIXES:
* Take ``smtp_server`` from user config into account.
(vila, #92195)
* Restore Unicode filename handling for versioned and unversioned files.
(John Arbash Meinel, #92608)
* Don't fail during ``bzr commit`` if a file is marked removed, and
the containing directory is auto-removed. (John Arbash Meinel, #93681)
* ``bzr status FILENAME`` failed on Windows because of an uncommon
errno. (``ERROR_DIRECTORY == 267 != ENOTDIR``).
(Wouter van Heyst, John Arbash Meinel, #90819)
* ``bzr checkout source`` should create a local branch in the same
format as source. (John Arbash Meinel, #93854)
* ``bzr commit`` with a kind change was failing to update the
last-changed-revision for directories. The
InventoryDirectory._unchanged only looked at the ``parent_id`` and name,
ignoring the fact that the kind could have changed, too.
(John Arbash Meinel, #90111)
* ``bzr mv dir/subdir other`` was incorrectly updating files inside
the directory. So that there was a chance it would break commit,
etc. (John Arbash Meinel, #94037)
* Correctly handles mutiple permanent http redirections.
(vila, #88780)
bzr 0.15rc2 2007-03-14
-----------------------
NOTES WHEN UPGRADING:
* Release 0.15rc2 of bzr changes the ``bzr init-repo`` command to
default to ``--trees`` instead of ``--no-trees``.
Existing shared repositories are not affected.
IMPROVEMENTS:
* New ``merge-directive`` command to generate machine- and human-readable
merge requests. (Aaron Bentley)
* New ``submit:`` revision specifier makes it easy to diff against the
common ancestor with the submit location (Aaron Bentley)
* Added support for Putty's SSH implementation. (Dmitry Vasiliev)
* Added ``bzr status --versioned`` to report only versioned files,
not unknowns. (Kent Gibson)
* Merge now autodetects the correct line-ending style for its conflict
markers. (Aaron Bentley)
INTERNALS:
* Refactored SSH vendor registration into SSHVendorManager class.
(Dmitry Vasiliev)
BUGFIXES:
* New ``--numbered-dirs`` option to ``bzr selftest`` to use
numbered dirs for TestCaseInTempDir. This is default behavior
on Windows. Anyone can force named dirs on Windows
with ``--no-numbered-dirs``. (Alexander Belchenko)
* Fix ``RevisionSpec_revid`` to handle the Unicode strings passed in
from the command line. (Marien Zwart, #90501)
* Fix ``TreeTransform._iter_changes`` when both the source and
destination are missing. (Aaron Bentley, #88842)
* Fix commit of merges with symlinks in dirstate trees.
(Marien Zwart)
* Switch the ``bzr init-repo`` default from --no-trees to --trees.
(Wouter van Heyst, #53483)
bzr 0.15rc1 2007-03-07
-----------------------
SURPRISES:
* The default disk format has changed. Please run 'bzr upgrade' in your
working trees to upgrade. This new default is compatible for network
operations, but not for local operations. That is, if you have two
versions of bzr installed locally, after upgrading you can only use the
bzr 0.15 version. This new default does not enable tags or nested-trees
as they are incompatible with bzr versions before 0.15 over the network.
* For users of bzrlib: Two major changes have been made to the working tree
api in bzrlib. The first is that many methods and attributes, including
the inventory attribute, are no longer valid for use until one of
``lock_read``/``lock_write``/``lock_tree_write`` has been called,
and become invalid again after unlock is called. This has been done
to improve performance and correctness as part of the dirstate
development.
(Robert Collins, John A Meinel, Martin Pool, and others).
* For users of bzrlib: The attribute 'tree.inventory' should be considered
readonly. Previously it was possible to directly alter this attribute, or
its contents, and have the tree notice this. This has been made
unsupported - it may work in some tree formats, but in the newer dirstate
format such actions will have no effect and will be ignored, or even
cause assertions. All operations possible can still be carried out by a
combination of the tree API, and the bzrlib.transform API. (Robert
Collins, John A Meinel, Martin Pool, and others).
IMPROVEMENTS:
* Support for OS Windows 98. Also .bzr.log on any windows system
saved in My Documents folder. (Alexander Belchenko)
* ``bzr mv`` enhanced to support already moved files.
In the past the mv command would have failed if the source file doesn't
exist. In this situation ``bzr mv`` would now detect that the file has
already moved and update the repository accordingly, if the target file
does exist.
A new option ``--after`` has been added so that if two files already
exist, you could notify Bazaar that you have moved a (versioned) file
and replaced it with another. Thus in this case ``bzr move --after``
will only update the Bazaar identifier.
(Steffen Eichenberg, Marius Kruger)
* ``ls`` now works on treeless branches and remote branches.
(Aaron Bentley)
* ``bzr help global-options`` describes the global options.
(Aaron Bentley)
* ``bzr pull --overwrite`` will now correctly overwrite checkouts.
(Robert Collins)
* Files are now allowed to change kind (e.g. from file to symlink).
Supported by ``commit``, ``revert`` and ``status``
(Aaron Bentley)
* ``inventory`` and ``unknowns`` hidden in favour of ``ls``
(Aaron Bentley)
* ``bzr help checkouts`` descibes what checkouts are and some possible
uses of them. (James Westby, Aaron Bentley)
* A new ``-d`` option to push, pull and merge overrides the default
directory. (Martin Pool)
* Branch format 6: smaller, and potentially faster than format 5. Supports
``append_history_only`` mode, where the log view and revnos do not change,
except by being added to. Stores policy settings in
".bzr/branch/branch.conf".
* ``append_only`` branches: Format 6 branches may be configured so that log
view and revnos are always consistent. Either create the branch using
"bzr init --append-revisions-only" or edit the config file as descriped
in docs/configuration.txt.
* rebind: Format 6 branches retain the last-used bind location, so if you
"bzr unbind", you can "bzr bind" to bind to the previously-selected
bind location.
* Builtin tags support, created and deleted by the ``tag`` command and
stored in the branch. Tags can be accessed with the revisionspec
``-rtag:``, and listed with ``bzr tags``. Tags are not versioned
at present. Tags require a network incompatible upgrade. To perform this
upgrade, run ``bzr upgrade --dirstate-tags`` in your branch and
repositories. (Martin Pool)
* The ``bzr://`` transport now has a well-known port number, 4155,
which it will use by default. (Andrew Bennetts, Martin Pool)
* Bazaar now looks for user-installed plugins before looking for site-wide
plugins. (Jonathan Lange)
* ``bzr resolve`` now detects and marks resolved text conflicts.
(Aaron Bentley)
INTERNALS:
* Internally revision ids and file ids are now passed around as utf-8
bytestrings, rather than treating them as Unicode strings. This has
performance benefits for Knits, since we no longer need to decode the
revision id for each line of content, nor for each entry in the index.
This will also help with the future dirstate format.
(John Arbash Meinel)
* Reserved ids (any revision-id ending in a colon) are rejected by
versionedfiles, repositories, branches, and working trees
(Aaron Bentley)
* Minor performance improvement by not creating a ProgressBar for
every KnitIndex we create. (about 90ms for a bzr.dev tree)
(John Arbash Meinel)
* New easier to use Branch hooks facility. There are five initial hooks,
all documented in bzrlib.branch.BranchHooks.__init__ - ``'set_rh'``,
``'post_push'``, ``'post_pull'``, ``'post_commit'``,
``'post_uncommit'``. These hooks fire after the matching operation
on a branch has taken place, and were originally added for the
branchrss plugin. (Robert Collins)
* New method ``Branch.push()`` which should be used when pushing from a
branch as it makes performance and policy decisions to match the UI
level command ``push``. (Robert Collins).
* Add a new method ``Tree.revision_tree`` which allows access to cached
trees for arbitrary revisions. This allows the in development dirstate
tree format to provide access to the callers to cached copies of
inventory data which are cheaper to access than inventories from the
repository.
(Robert Collins, Martin Pool)
* New ``Branch.last_revision_info`` method, this is being done to allow
optimization of requests for both the number of revisions and the last
revision of a branch with smartservers and potentially future branch
formats. (Wouter van Heyst, Robert Collins)
* Allow ``'import bzrlib.plugins.NAME'`` to work when the plugin NAME has not
yet been loaded by ``load_plugins()``. This allows plugins to depend on each
other for code reuse without requiring users to perform file-renaming
gymnastics. (Robert Collins)
* New Repository method ``'gather_stats'`` for statistic data collection.
This is expected to grow to cover a number of related uses mainly
related to bzr info. (Robert Collins)
* Log formatters are now managed with a registry.
``log.register_formatter`` continues to work, but callers accessing
the FORMATTERS dictionary directly will not.
* Allow a start message to be passed to the ``edit_commit_message``
function. This will be placed in the message offered to the user
for editing above the separator. It allows a template commit message
to be used more easily. (James Westby)
* ``GPGStrategy.sign()`` will now raise ``BzrBadParameterUnicode`` if
you pass a Unicode string rather than an 8-bit string. Callers need
to be updated to encode first. (John Arbash Meinel)
* Branch.push, pull, merge now return Result objects with information
about what happened, rather than a scattering of various methods. These
are also passed to the post hooks. (Martin Pool)
* File formats and architecture is in place for managing a forest of trees
in bzr, and splitting up existing trees into smaller subtrees, and
finally joining trees to make a larger tree. This is the first iteration
of this support, and the user-facing aspects still require substantial
work. If you wish to experiment with it, use ``bzr upgrade
--dirstate-with-subtree`` in your working trees and repositories.
You can use the hidden commands ``split`` and ``join`` and to create
and manipulate nested trees, but please consider using the nested-trees
branch, which contains substantial UI improvements, instead.
http://code.aaronbentley.com/bzr/bzrrepo/nested-trees/
(Aaron Bentley, Martin Pool, Robert Collins).
BUGFIXES:
* ``bzr annotate`` now uses dotted revnos from the viewpoint of the
branch, rather than the last changed revision of the file.
(John Arbash Meinel, #82158)
* Lock operations no longer hang if they encounter a permission problem.
(Aaron Bentley)
* ``bzr push`` can resume a push that was canceled before it finished.
Also, it can push even if the target directory exists if you supply
the ``--use-existing-dir`` flag.
(John Arbash Meinel, #30576, #45504)
* Fix http proxy authentication when user and an optional
password appears in the ``*_proxy`` vars. (Vincent Ladeuil,
#83954).
* ``bzr log branch/file`` works for local treeless branches
(Aaron Bentley, #84247)
* Fix problem with UNC paths on Windows 98. (Alexander Belchenko, #84728)
* Searching location of CA bundle for PyCurl in env variable
(``CURL_CA_BUNDLE``), and on win32 along the PATH.
(Alexander Belchenko, #82086)
* ``bzr init`` works with unicode argument LOCATION.
(Alexander Belchenko, #85599)
* Raise ``DependencyNotPresent`` if pycurl do not support https.
(Vincent Ladeuil, #85305)
* Invalid proxy env variables should not cause a traceback.
(Vincent Ladeuil, #87765)
* Ignore patterns normalised to use '/' path separator.
(Kent Gibson, #86451)
* bzr rocks. It sure does! Fix case. (Vincent Ladeuil, #78026)
* Fix bzrtools shelve command for removed lines beginning with "--"
(Johan Dahlberg, #75577)
TESTING:
* New ``--first`` option to ``bzr selftest`` to run specified tests
before the rest of the suite. (Martin Pool)
bzr 0.14 2007-01-23
--------------------
IMPROVEMENTS:
* ``bzr help global-options`` describes the global options. (Aaron Bentley)
BUG FIXES:
* Skip documentation generation tests if the tools to do so are not
available. Fixes running selftest for installled copies of bzr.
(John Arbash Meinel, #80330)
* Fix the code that discovers whether bzr is being run from it's
working tree to handle the case when it isn't but the directory
it is in is below a repository. (James Westby, #77306)
bzr 0.14rc1 2007-01-16
-----------------------
IMPROVEMENTS:
* New connection: ``bzr+http://`` which supports tunnelling the smart
protocol over an HTTP connection. If writing is enabled on the bzr
server, then you can write over the http connection.
(Andrew Bennetts, John Arbash Meinel)
* Aliases now support quotation marks, so they can contain whitespace
(Marius Kruger)
* PyCurlTransport now use a single curl object. By specifying explicitly
the 'Range' header, we avoid the need to use two different curl objects
(and two connections to the same server). (Vincent Ladeuil)
* ``bzr commit`` does not prompt for a message until it is very likely to
succeed. (Aaron Bentley)
* ``bzr conflicts`` now takes --text to list pathnames of text conflicts
(Aaron Bentley)
* Fix ``iter_lines_added_or_present_in_versions`` to use a set instead
of a list while checking if a revision id was requested. Takes 10s
off of the ``fileids_affected_by_revision_ids`` time, which is 10s
of the ``bzr branch`` time. Also improve ``fileids_...`` time by
filtering lines with a regex rather than multiple ``str.find()``
calls. (saves another 300ms) (John Arbash Meinel)
* Policy can be set for each configuration key. This allows keys to be
inherited properly across configuration entries. For example, this
should enable you to do::
[/home/user/project]
push_location = sftp://host/srv/project/
push_location:policy = appendpath
And then a branch like ``/home/user/project/mybranch`` should get an
automatic push location of ``sftp://host/srv/project/mybranch``.
(James Henstridge)
* Added ``bzr status --short`` to make status report svn style flags
for each file. For example::
$ bzr status --short
A foo
A bar
D baz
? wooley
* 'bzr selftest --clean-output' allows easily clean temporary tests
directories without running tests. (Alexander Belchenko)
* ``bzr help hidden-commands`` lists all hidden commands. (Aaron Bentley)
* ``bzr merge`` now has an option ``--pull`` to fall back to pull if
local is fully merged into remote. (Jan Hudec)
* ``bzr help formats`` describes available directory formats. (Aaron Bentley)
INTERNALS:
* A few tweaks directly to ``fileids_affected_by_revision_ids`` to
help speed up processing, as well allowing to extract unannotated
lines. Between the two ``fileids_affected_by_revision_ids`` is
improved by approx 10%. (John Arbash Meinel)
* Change Revision serialization to only write out millisecond
resolution. Rather than expecting floating point serialization to
preserve more resolution than we need. (Henri Weichers, Martin Pool)
* Test suite ends cleanly on Windows. (Vincent Ladeuil)
* When ``encoding_type`` attribute of class Command is equal to 'exact',
force sys.stdout to be a binary stream on Windows, and therefore
keep exact line-endings (without LF -> CRLF conversion).
(Alexander Belchenko)
* Single-letter short options are no longer globally declared. (Martin
Pool)
* Before using detected user/terminal encoding bzr should check
that Python has corresponding codec. (Alexander Belchenko)
* Formats for end-user selection are provided via a FormatRegistry (Aaron Bentley)
BUG FIXES:
* ``bzr missing --verbose`` was showing adds/removals in the wrong
direction. (John Arbash Meinel)
* ``bzr annotate`` now defaults to showing dotted revnos for merged
revisions. It cuts them off at a depth of 12 characters, but you can
supply ``--long`` to see the full number. You can also use
``--show-ids`` to display the original revision ids, rather than
revision numbers and committer names. (John Arbash Meinel, #75637)
* bzr now supports Win32 UNC path (e.g. ``\HOST\path``.
(Alexander Belchenko, #57869)
* Win32-specific: output of cat, bundle and diff commands don't mangle
line-endings (Alexander Belchenko, #55276)
* Replace broken fnmatch based ignore pattern matching with custom pattern
matcher.
(Kent Gibson, Jan Hudec #57637)
* pycurl and urllib can detect short reads at different places. Update
the test suite to test more cases. Also detect http error code 416
which was raised for that specific bug. Also enhance the urllib
robustness by detecting invalid ranges (and pycurl's one by detecting
short reads during the initial GET). (Vincent Ladeuil, #73948)
* The urllib connection sharing interacts badly with urllib2
proxy setting (the connections didn't go thru the proxy
anymore). Defining a proper ProxyHandler solves the
problem. (Vincent Ladeuil, #74759)
* Use urlutils to generate relative URLs, not osutils
(Aaron Bentley, #76229)
* ``bzr status`` in a readonly directory should work without giving
lots of errors. (John Arbash Meinel, #76299)
* Mention the revisionspec topic for the revision option help.
(Wouter van Heyst, #31663)
* Allow plugins import from zip archives.
(Alexander Belchenko, #68124)
bzr 0.13 2006-12-05
--------------------
No changes from 0.13rc1
bzr 0.13rc1 2006-11-27
-----------------------
IMPROVEMENTS:
* New command ``bzr remove-tree`` allows the removal of the working
tree from a branch.
(Daniel Silverstone)
* urllib uses shared keep-alive connections, so http
operations are substantially faster.
(Vincent Ladeuil, #53654)
* ``bzr export`` allows an optional branch parameter, to export a bzr
tree from some other url. For example:
``bzr export bzr.tar.gz http://bazaar-vcs.org/bzr/bzr.dev``
(Daniel Silverstone)
* Added ``bzr help topics`` to the bzr help system. This gives a
location for general information, outside of a specific command.
This includes updates for ``bzr help revisionspec`` the first topic
included. (Goffredo Baroncelli, John Arbash Meinel, #42714)
* WSGI-compatible HTTP smart server. See ``doc/http_smart_server.txt``.
(Andrew Bennetts)
* Knit files will now cache full texts only when the size of the
deltas is as large as the size of the fulltext. (Or after 200
deltas, whichever comes first). This has the most benefit on large
files with small changes, such as the inventory for a large project.
(eg For a project with 2500 files, and 7500 revisions, it changes
the size of inventory.knit from 11MB to 5.4MB) (John Arbash Meinel)
INTERNALS:
* New -D option given before the command line turns on debugging output
for particular areas. -Derror shows tracebacks on all errors.
(Martin Pool)
* Clean up ``bzr selftest --benchmark bundle`` to correct an import,
and remove benchmarks that take longer than 10min to run.
(John Arbash Meinel)
* Use ``time.time()`` instead of ``time.clock()`` to decide on
progress throttling. Because ``time.clock()`` is actually CPU time,
so over a high-latency connection, too many updates get throttled.
(John Arbash Meinel)
* ``MemoryTransport.list_dir()`` would strip the first character for
files or directories in root directory. (John Arbash Meinel)
* New method ``get_branch_reference`` on 'BzrDir' allows the detection of
branch references - which the smart server component needs.
* New ``ChrootTransportDecorator``, accessible via the ``chroot+`` url
prefix. It disallows any access to locations above a set URL. (Andrew
Bennetts)
BUG FIXES:
* Now ``_KnitIndex`` properly decode revision ids when loading index data.
And optimize the knit index parsing code.
(Dmitry Vasiliev, John Arbash Meinel)
* ``bzrlib/bzrdir.py`` was directly referencing ``bzrlib.workingtree``,
without importing it. This prevented ``bzr upgrade`` from working
unless a plugin already imported ``bzrlib.workingtree``
(John Arbash Meinel, #70716)
* Suppress the traceback on invalid URLs (Vincent Ladeuil, #70803).
* Give nicer error message when an http server returns a 403
error code. (Vincent Ladeuil, #57644).
* When a multi-range http GET request fails, try a single
range one. If it fails too, forget about ranges. Remember that until
the death of the transport and propagates that to the clones.
(Vincent Ladeuil, #62276, #62029).
* Handles user/passwords supplied in url from command
line (for the urllib implementation). Don't request already
known passwords (Vincent Ladeuil, #42383, #44647, #48527)
* ``_KnitIndex.add_versions()`` dictionary compresses revision ids as they
are added. This fixes bug where fetching remote revisions records
them as full references rather than integers.
(John Arbash Meinel, #64789)
* ``bzr ignore`` strips trailing slashes in patterns.
Also ``bzr ignore`` rejects absolute paths. (Kent Gibson, #4559)
* ``bzr ignore`` takes multiple arguments. (Cheuksan Edward Wang, #29488)
* mv correctly handles paths that traverse symlinks.
(Aaron Bentley, #66964)
* Give nicer looking error messages when failing to connect over ssh.
(John Arbash Meinel, #49172)
* Pushing to a remote branch does not currently update the remote working
tree. After a remote push, ``bzr status`` and ``bzr diff`` on the remote
machine now show that the working tree is out of date.
(Cheuksan Edward Wang #48136)
* Use patiencediff instead of difflib for determining deltas to insert
into knits. This avoids the O(N^3) behavior of difflib. Patience
diff should be O(N^2). (Cheuksan Edward Wang, #65714)
* Running ``bzr log`` on nonexistent file gives an error instead of the
entire log history. (Cheuksan Edward Wang #50793)
* ``bzr cat`` can look up contents of removed or renamed files. If the
pathname is ambiguous, i.e. the files in the old and new trees have
different id's, the default is the file in the new tree. The user can
use "--name-from-revision" to select the file in the old tree.
(Cheuksan Edward Wang, #30190)
TESTING:
* TestingHTTPRequestHandler really handles the Range header
(previously it was ignoring it and returning the whole file,).
bzr 0.12 2006-10-30
--------------------
INTERNALS:
* Clean up ``bzr selftest --benchmark bundle`` to correct an import,
and remove benchmarks that take longer than 10min to run.
(John Arbash Meinel)
bzr 0.12rc1 2006-10-23
-----------------------
IMPROVEMENTS:
* ``bzr log`` now shows dotted-decimal revision numbers for all revisions,
rather than just showing a decimal revision number for revisions on the
mainline. These revision numbers are not yet accepted as input into bzr
commands such as log, diff etc. (Robert Collins)
* revisions can now be specified using dotted-decimal revision numbers.
For instance, ``bzr diff -r 1.2.1..1.2.3``. (Robert Collins)
* ``bzr help commands`` output is now shorter (Aaron Bentley)
* ``bzr`` now uses lazy importing to reduce the startup time. This has
a moderate effect on lots of actions, especially ones that have
little to do. For example ``bzr rocks`` time is down to 116ms from
283ms. (John Arbash Meinel)
* New Registry class to provide name-to-object registry-like support,
for example for schemes where plugins can register new classes to
do certain tasks (e.g. log formatters). Also provides lazy registration
to allow modules to be loaded on request.
(John Arbash Meinel, Adeodato Simó)
API INCOMPATABILITY:
* LogFormatter subclasses show now expect the 'revno' parameter to
show() to be a string rather than an int. (Robert Collins)
INTERNALS:
* ``TestCase.run_bzr``, ``run_bzr_captured``, and ``run_bzr_subprocess``
can take a ``working_dir='foo'`` parameter, which will change directory
for the command. (John Arbash Meinel)
* ``bzrlib.lazy_regex.lazy_compile`` can be used to create a proxy
around a regex, which defers compilation until first use.
(John Arbash Meinel)
* ``TestCase.run_bzr_subprocess`` defaults to supplying the
``--no-plugins`` parameter to ensure test reproducability, and avoid
problems with system-wide installed plugins. (John Arbash Meinel)
* Unique tree root ids are now supported. Newly created trees still
use the common root id for compatibility with bzr versions before 0.12.
(Aaron Bentley)
* ``WorkingTree.set_root_id(None)`` is now deprecated. Please
pass in ``inventory.ROOT_ID`` if you want the default root id value.
(Robert Collins, John Arbash Meinel)
* New method ``WorkingTree.flush()`` which will write the current memory
inventory out to disk. At the same time, ``read_working_inventory`` will
no longer trash the current tree inventory if it has been modified within
the current lock, and the tree will now ``flush()`` automatically on
``unlock()``. ``WorkingTree.set_root_id()`` has been updated to take
advantage of this functionality. (Robert Collins, John Arbash Meinel)
* ``bzrlib.tsort.merge_sorted`` now accepts ``generate_revnos``. This
parameter will cause it to add another column to its output, which
contains the dotted-decimal revno for each revision, as a tuple.
(Robert Collins)
* ``LogFormatter.show_merge`` is deprecated in favour of
``LogFormatter.show_merge_revno``. (Robert Collins)
BUG FIXES:
* Avoid circular imports by creating a deprecated function for
``bzrlib.tree.RevisionTree``. Callers should have been using
``bzrlib.revisontree.RevisionTree`` anyway. (John Arbash Meinel,
#63360, #66349)
* Don't use ``socket.MSG_WAITALL`` as it doesn't exist on all
platforms. (Martin Pool, #66356)
* Don't require ``Content-Type`` in range responses. Assume they are a
single range if ``Content-Type`` does not exist.
(John Arbash Meinel, #62473)
* bzr branch/pull no longer complain about progress bar cleanup when
interrupted during fetch. (Aaron Bentley, #54000)
* ``WorkingTree.set_parent_trees()`` uses the trees to directly write
the basis inventory, rather than going through the repository. This
allows us to have 1 inventory read, and 2 inventory writes when
committing a new tree. (John Arbash Meinel)
* When reverting, files that are not locally modified that do not exist
in the target are deleted, not just unversioned (Aaron Bentley)
* When trying to acquire a lock, don't fail immediately. Instead, try
a few times (up to 1 hour) before timing out. Also, report why the
lock is unavailable (John Arbash Meinel, #43521, #49556)
* Leave HttpTransportBase daughter classes decides how they
implement cloning. (Vincent Ladeuil, #61606)
* diff3 does not indicate conflicts on clean merge. (Aaron Bentley)
* If a commit fails, the commit message is stored in a file at the root of
the tree for later commit. (Cheuksan Edward Wang, Stefan Metzmacher,
#32054)
TESTING:
* New test base class TestCaseWithMemoryTransport offers memory-only
testing facilities: its not suitable for tests that need to mutate disk
state, but most tests should not need that and should be converted to
TestCaseWithMemoryTransport. (Robert Collins)
* ``TestCase.make_branch_and_memory_tree`` now takes a format
option to set the BzrDir, Repository and Branch formats of the
created objects. (Robert Collins, John Arbash Meinel)
bzr 0.11 2006-10-02
--------------------
* Smart server transport test failures on windows fixed. (Lukáš Lalinský).
bzr 0.11rc2 2006-09-27
-----------------------
BUG FIXES:
* Test suite hangs on windows fixed. (Andrew Bennets, Alexander Belchenko).
* Commit performance regression fixed. (Aaron Bentley, Robert Collins, John
Arbash Meinel).
bzr 0.11rc1 2006-09-25
-----------------------
IMPROVEMENTS:
* Knit files now wait to create their contents until the first data is
added. The old code used to create an empty .knit and a .kndx with just
the header. However, this caused a lot of extra round trips over sftp.
This can change the time for ``bzr push`` to create a new remote branch
from 160s down to 100s. This also affects ``bzr commit`` performance when
adding new files, ``bzr commit`` on a new kernel-like tree drops from 50s
down to 40s (John Arbash Meinel, #44692)
* When an entire subtree has been deleted, commit will now report that
just the top of the subtree has been deleted, rather than reporting
all the individual items. (Robert Collins)
* Commit performs one less XML parse. (Robert Collins)
* ``bzr checkout`` now operates on readonly branches as well
as readwrite branches. This fixes bug #39542. (Robert Collins)
* ``bzr bind`` no longer synchronises history with the master branch.
Binding should be followed by an update or push to synchronise the
two branches. This is closely related to the fix for bug #39542.
(Robert Collins)
* ``bzrlib.lazy_import.lazy_import`` function to create on-demand
objects. This allows all imports to stay at the global scope, but
modules will not actually be imported if they are not used.
(John Arbash Meinel)
* Support ``bzr://`` and ``bzr+ssh://`` urls to work with the new RPC-based
transport which will be used with the upcoming high-performance smart
server. The new command ``bzr serve`` will invoke bzr in server mode,
which processes these requests. (Andrew Bennetts, Robert Collins, Martin
Pool)
* New command ``bzr version-info`` which can be used to get a summary
of the current state of the tree. This is especially useful as part
of a build commands. See ``doc/version_info.txt`` for more information
(John Arbash Meinel)
BUG FIXES:
* ``'bzr inventory [FILE...]'`` allows restricting the file list to a
specific set of files. (John Arbash Meinel, #3631)
* Don't abort when annotating empty files (John Arbash Meinel, #56814)
* Add ``Stanza.to_unicode()`` which can be passed to another Stanza
when nesting stanzas. Also, add ``read_stanza_unicode`` to handle when
reading a nested Stanza. (John Arbash Meinel)
* Transform._set_mode() needs to stat the right file.
(John Arbash Meinel, #56549)
* Raise WeaveFormatError rather than StopIteration when trying to read
an empty Weave file. (John Arbash Meinel, #46871)
* Don't access e.code for generic URLErrors, only HTTPErrors have .code.
(Vincent Ladeuil, #59835)
* Handle boundary="" lines properly to allow access through a Squid proxy.
(John Arbash Meinel, #57723)
* revert now removes newly-added directories (Aaron Bentley, #54172)
* ``bzr upgrade sftp://`` shouldn't fail to upgrade v6 branches if there
isn't a working tree. (David Allouche, #40679)
* Give nicer error messages when a user supplies an invalid --revision
parameter. (John Arbash Meinel, #55420)
* Handle when LANG is not recognized by python. Emit a warning, but
just revert to using 'ascii'. (John Arbash Meinel, #35392)
* Don't use ``preexec_fn`` on win32, as it is not supported by subprocess.
(John Arbash Meinel)
* Skip specific tests when the dependencies aren't met. This includes
some ``setup.py`` tests when ``python-dev`` is not available, and
some tests that depend on paramiko. (John Arbash Meinel, Mattheiu Moy)
* Fallback to Paramiko properly, if no ``ssh`` executable exists on
the system. (Andrew Bennetts, John Arbash Meinel)
* ``Branch.bind(other_branch)`` no longer takes a write lock on the
other branch, and will not push or pull between the two branches.
API users will need to perform a push or pull or update operation if they
require branch synchronisation to take place. (Robert Collins, #47344)
* When creating a tarball or zipfile export, export unicode names as utf-8
paths. This may not work perfectly on all platforms, but has the best
chance of working in the common case. (John Arbash Meinel, #56816)
* When committing, only files that exist in working tree or basis tree
may be specified (Aaron Bentley, #50793)
PORTABILITY:
* Fixes to run on Python 2.5 (Brian M. Carlson, Martin Pool, Marien Zwart)
INTERNALS:
* TestCaseInTempDir now creates a separate directory for HOME, rather
than having HOME set to the same location as the working directory.
(John Arbash Meinel)
* ``run_bzr_subprocess()`` can take an optional ``env_changes={}`` parameter,
which will update os.environ inside the spawned child. It also can
take a ``universal_newlines=True``, which helps when checking the output
of the command. (John Arbash Meinel)
* Refactor SFTP vendors to allow easier re-use when ssh is used.
(Andrew Bennetts)
* ``Transport.list_dir()`` and ``Transport.iter_files_recursive()`` should always
return urlescaped paths. This is now tested (there were bugs in a few
of the transports) (Andrew Bennetts, David Allouche, John Arbash Meinel)
* New utility function ``symbol_versioning.deprecation_string``. Returns the
formatted string for a callable, deprecation format pair. (Robert Collins)
* New TestCase helper applyDeprecated. This allows you to call a callable
which is deprecated without it spewing to the screen, just by supplying
the deprecation format string issued for it. (Robert Collins)
* Transport.append and Transport.put have been deprecated in favor of
``.append_bytes``, ``.append_file``, ``.put_bytes``, and
``.put_file``. This removes the ambiguity in what type of object the
functions take. ``Transport.non_atomic_put_{bytes,file}`` has also
been added. Which works similarly to ``Transport.append()`` except for
SFTP, it doesn't have a round trip when opening the file. Also, it
provides functionality for creating a parent directory when trying
to create a file, rather than raise NoSuchFile and forcing the
caller to repeat their request.
(John Arbash Meinel)
* WorkingTree has a new api ``unversion`` which allow the unversioning of
entries by their file id. (Robert Collins)
* ``WorkingTree.pending_merges`` is deprecated. Please use the
``get_parent_ids`` (introduced in 0.10) method instead. (Robert Collins)
* WorkingTree has a new ``lock_tree_write`` method which locks the branch for
read rather than write. This is appropriate for actions which only need
the branch data for reference rather than mutation. A new decorator
``needs_tree_write_lock`` is provided in the workingtree module. Like the
``needs_read_lock`` and ``needs_write_lock`` decorators this allows static
declaration of the locking requirements of a function to ensure that
a lock is taken out for casual scripts. (Robert Collins, #54107)
* All WorkingTree methods which write to the tree, but not to the branch
have been converted to use ``needs_tree_write_lock`` rather than
``needs_write_lock``. Also converted is the revert, conflicts and tree
transform modules. This provides a modest performance improvement on
metadir style trees, due to the reduce lock-acquisition, and a more
significant performance improvement on lightweight checkouts from
remote branches, where trivial operations used to pay a significant
penalty. It also provides the basis for allowing readonly checkouts.
(Robert Collins)
* Special case importing the standard library 'copy' module. This shaves
off 40ms of startup time, while retaining compatibility. See:
``bzrlib/inspect_for_copy.py`` for more details. (John Arbash Meinel)
* WorkingTree has a new parent class MutableTree which represents the
specialisations of Tree which are able to be altered. (Robert Collins)
* New methods mkdir and ``put_file_bytes_non_atomic`` on MutableTree that
mutate the tree and its contents. (Robert Collins)
* Transport behaviour at the root of the URL is now defined and tested.
(Andrew Bennetts, Robert Collins)
TESTING:
* New test helper classs MemoryTree. This is typically accessed via
``self.make_branch_and_memory_tree()`` in test cases. (Robert Collins)
* Add ``start_bzr_subprocess`` and ``stop_bzr_subprocess`` to allow test
code to continue running concurrently with a subprocess of bzr.
(Andrew Bennetts, Robert Collins)
* Add a new method ``Transport.get_smart_client()``. This is provided to
allow upgrades to a richer interface than the VFS one provided by
Transport. (Andrew Bennetts, Martin Pool)
bzr 0.10 2006-08-29
--------------------
IMPROVEMENTS:
* 'merge' now takes --uncommitted, to apply uncommitted changes from a
tree. (Aaron Bentley)
* 'bzr add --file-ids-from' can be used to specify another path to use
for creating file ids, rather than generating all new ones. Internally,
the 'action' passed to ``smart_add_tree()`` can return ``file_ids`` that
will be used, rather than having bzrlib generate new ones.
(John Arbash Meinel, #55781)
* ``bzr selftest --benchmark`` now allows a ``--cache-dir`` parameter.
This will cache some of the intermediate trees, and decrease the
setup time for benchmark tests. (John Arbash Meinel)
* Inverse forms are provided for all boolean options. For example,
--strict has --no-strict, --no-recurse has --recurse (Aaron Bentley)
* Serialize out Inventories directly, rather than using ElementTree.
Writing out a kernel sized inventory drops from 2s down to ~350ms.
(Robert Collins, John Arbash Meinel)
BUG FIXES:
* Help diffutils 2.8.4 get along with binary tests (Marien Zwart: #57614)
* Change LockDir so that if the lock directory doesn't exist when
``lock_write()`` is called, an attempt will be made to create it.
(John Arbash Meinel, #56974)
* ``bzr uncommit`` preserves pending merges. (John Arbash Meinel, #57660)
* Active FTP transport now works as intended. (ghozzy, #56472)
* Really fix mutter() so that it won't ever raise a UnicodeError.
It means it is possible for ~/.bzr.log to contain non UTF-8 characters.
But it is a debugging log, not a real user file.
(John Arbash Meinel, #56947, #53880)
* Change Command handle to allow Unicode command and options.
At present we cannot register Unicode command names, so we will get
BzrCommandError('unknown command'), or BzrCommandError('unknown option')
But that is better than a UnicodeError + a traceback.
(John Arbash Meinel, #57123)
* Handle TZ=UTC properly when reading/writing revisions.
(John Arbash Meinel, #55783, #56290)
* Use ``GPG_TTY`` to allow gpg --cl to work with gpg-agent in a pipeline,
(passing text to sign in on stdin). (John Arbash Meinel, #54468)
* External diff does the right thing for binaries even in foreign
languages. (John Arbash Meinel, #56307)
* Testament handles more cases when content is unicode. Specific bug was
in handling of revision properties.
(John Arbash Meinel, Holger Krekel, #54723)
* The bzr selftest was failing on installed versions due to a bug in a new
test helper. (John Arbash Meinel, Robert Collins, #58057)
INTERNALS:
* ``bzrlib.cache_utf8`` contains ``encode()`` and ``decode()`` functions
which can be used to cache the conversion between utf8 and Unicode.
Especially helpful for some of the knit annotation code, which has to
convert revision ids to utf8 to annotate lines in storage.
(John Arbash Meinel)
* ``setup.py`` now searches the filesystem to find all packages which
need to be installed. This should help make the life of packagers
easier. (John Arbash Meinel)
bzr 0.9.0 2006-08-11
---------------------
SURPRISES:
* The hard-coded built-in ignore rules have been removed. There are
now two rulesets which are enforced. A user global one in
``~/.bazaar/ignore`` which will apply to every tree, and the tree
specific one '.bzrignore'.
``~/.bazaar/ignore`` will be created if it does not exist, but with
a more conservative list than the old default.
This fixes bugs with default rules being enforced no matter what.
The old list of ignore rules from bzr is available by
running 'bzr ignore --old-default-rules'.
(Robert Collins, Martin Pool, John Arbash Meinel)
* 'branches.conf' has been changed to 'locations.conf', since it can apply
to more locations than just branch locations.
(Aaron Bentley)
IMPROVEMENTS:
* The revision specifier "revno:" is extended to accept the syntax
revno:N:branch. For example,
revno:42:http://bazaar-vcs.org/bzr/bzr.dev/ means revision 42 in
bzr.dev. (Matthieu Moy)
* Tests updates to ensure proper URL handling, UNICODE support, and
proper printing when the user's terminal encoding cannot display
the path of a file that has been versioned.
``bzr branch`` can take a target URL rather than only a local directory.
``Branch.get_parent()/set_parent()`` now save a relative path if possible,
and normalize the parent based on root, allowing access across
different transports. (John Arbash Meinel, Wouter van Heyst, Martin Pool)
(Malone #48906, #42699, #40675, #5281, #3980, #36363, #43689,
#42517, #42514)
* On Unix, detect terminal width using an ioctl not just $COLUMNS.
Use terminal width for single-line logs from ``bzr log --line`` and
pending-merge display. (Robert Widhopf-Fenk, Gustavo Niemeyer)
(Malone #3507)
* On Windows, detect terminal width using GetConsoleScreenBufferInfo.
(Alexander Belchenko)
* Speedup improvement for 'date:'-revision search. (Guillaume Pinot).
* Show the correct number of revisions pushed when pushing a new branch.
(Robert Collins).
* 'bzr selftest' now shows a progress bar with the number of tests, and
progress made. 'make check' shows tests in -v mode, to be more useful
for the PQM status window. (Robert Collins).
When using a progress bar, failed tests are printed out, rather than
being overwritten by the progress bar until the suite finishes.
(John Arbash Meinel)
* 'bzr selftest --benchmark' will run a new benchmarking selftest.
'bzr selftest --benchmark --lsprof-timed' will use lsprofile to generate
profile data for the individual profiled calls, allowing for fine
grained analysis of performance.
(Robert Collins, Martin Pool).
* 'bzr commit' shows a progress bar. This is useful for commits over sftp
where commit can take an appreciable time. (Robert Collins)
* 'bzr add' is now less verbose in telling you what ignore globs were
matched by files being ignored. Instead it just tells you how many
were ignored (because you might reasonably be expecting none to be
ignored). 'bzr add -v' is unchanged and will report every ignored
file. (Robert Collins).
* ftp now has a test server if medusa is installed. As part of testing,
ftp support has been improved, including support for supplying a
non-standard port. (John Arbash Meinel).
* 'bzr log --line' shows the revision number, and uses only the
first line of the log message (#5162, Alexander Belchenko;
Matthieu Moy)
* 'bzr status' has had the --all option removed. The 'bzr ls' command
should be used to retrieve all versioned files. (Robert Collins)
* 'bzr bundle OTHER/BRANCH' will create a bundle which can be sent
over email, and applied on the other end, while maintaining ancestry.
This bundle can be applied with either 'bzr merge' or 'bzr pull',
the same way you would apply another branch.
(John Arbash Meinel, Aaron Bentley)
* 'bzr whoami' can now be used to set your identity from the command line,
for a branch or globally. (Robey Pointer)
* 'bzr checkout' now aliased to 'bzr co', and 'bzr annotate' to 'bzr ann'.
(Michael Ellerman)
* 'bzr revert DIRECTORY' now reverts the contents of the directory as well.
(Aaron Bentley)
* 'bzr get sftp://foo' gives a better error when paramiko is not present.
Also updates things like 'http+pycurl://' if pycurl is not present.
(John Arbash Meinel) (Malone #47821, #52204)
* New env variable ``BZR_PROGRESS_BAR``, sets the default progress bar type.
Can be set to 'none' or 'dummy' to disable the progress bar, 'dots' or
'tty' to create the respective type. (John Arbash Meinel, #42197, #51107)
* Improve the help text for 'bzr diff' to explain what various options do.
(John Arbash Meinel, #6391)
* 'bzr uncommit -r 10' now uncommits revisions 11.. rather than uncommitting
revision 10. This makes -r10 more in line with what other commands do.
'bzr uncommit' also now saves the pending merges of the revisions that
were removed. So it is safe to uncommit after a merge, fix something,
and commit again. (John Arbash Meinel, #32526, #31426)
* 'bzr init' now also works on remote locations.
(Wouter van Heyst, #48904)
* HTTP support has been updated. When using pycurl we now support
connection keep-alive, which reduces dns requests and round trips.
And for both urllib and pycurl we support multi-range requests,
which decreases the number of round-trips. Performance results for
``bzr branch http://bazaar-vcs.org/bzr/bzr.dev/`` indicate
http branching is now 2-3x faster, and ``bzr pull`` in an existing
branch is as much as 4x faster.
(Michael Ellerman, Johan Rydberg, John Arbash Meinel, #46768)
* Performance improvements for sftp. Branching and pulling are now up to
2x faster. Utilize paramiko.readv() support for async requests if it
is available (paramiko > 1.6) (John Arbash Meinel)
BUG FIXES:
* Fix shadowed definition of TestLocationConfig that caused some
tests not to run.
(Erik BÃ¥gfors, Michael Ellerman, Martin Pool, #32587)
* Fix unnecessary requirement of sign-my-commits that it be run from
a working directory. (Martin Pool, Robert Collins)
* 'bzr push location' will only remember the push location if it succeeds
in connecting to the remote location. (John Arbash Meinel, #49742)
* 'bzr revert' no longer toggles the executable bit on win32
(John Arbash Meinel, #45010)
* Handle broken pipe under win32 correctly. (John Arbash Meinel)
* sftp tests now work correctly on win32 if you have a newer paramiko
(John Arbash Meinel)
* Cleanup win32 test suite, and general cleanup of places where
file handles were being held open. (John Arbash Meinel)
* When specifying filenames for 'diff -r x..y', the name of the file in the
working directory can be used, even if its name is different in both x
and y.
* File-ids containing single- or double-quotes are handled correctly by
push. (Aaron Bentley, #52227)
* Normalize unicode filenames to ensure cross-platform consistency.
(John Arbash Meinel, #43689)
* The argument parser can now handle '-' as an argument. Currently
no code interprets it specially (it is mostly handled as a file named
'-'). But plugins, and future operations can use it.
(John Arbash meinel, #50984)
* Bundles can properly read binary files with a plain '\r' in them.
(John Arbash Meinel, #51927)
* Tuning ``iter_entries()`` to be more efficient (John Arbash Meinel, #5444)
* Lots of win32 fixes (the test suite passes again).
(John Arbash Meinel, #50155)
* Handle openbsd returning None for sys.getfilesystemencoding() (#41183)
* Support ftp APPE (append) to allow Knits to be used over ftp (#42592)
* Removals are only committed if they match the filespec (or if there is
no filespec). (#46635, Aaron Bentley)
* smart-add recurses through all supplied directories
(John Arbash Meinel, #52578)
* Make the bundle reader extra lines before and after the bundle text.
This allows you to parse an email with the bundle inline.
(John Arbash Meinel, #49182)
* Change the file id generator to squash a little bit more. Helps when
working with long filenames on windows. (Also helps for unicode filenames
not generating hidden files). (John Arbash Meinel, #43801)
* Restore terminal mode on C-c while reading sftp password. (#48923,
Nicholas Allen, Martin Pool)
* Timestamps are rounded to 1ms, and revision entries can be recreated
exactly. (John Arbash Meinel, Jamie Wilkinson, #40693)
* Branch.base has changed to a URL, but ~/.bazaar/locations.conf should
use local paths, since it is user visible (John Arbash Meinel, #53653)
* ``bzr status foo`` when foo was unversioned used to cause a full delta
to be generated (John Arbash Meinel, #53638)
* When reading revision properties, an empty value should be considered
the empty string, not None (John Arbash Meinel, #47782)
* ``bzr diff --diff-options`` can now handle binary files being changed.
Also, the output is consistent when --diff-options is not supplied.
(John Arbash Meinel, #54651, #52930)
* Use the right suffixes for loading plugins (John Arbash Meinel, #51810)
* Fix ``Branch.get_parent()`` to handle the case when the parent is not
accessible (John Arbash Meinel, #52976)
INTERNALS:
* Combine the ignore rules into a single regex rather than looping over
them to reduce the threshold where N^2 behaviour occurs in operations
like status. (Jan Hudec, Robert Collins).
* Appending to ``bzrlib.DEFAULT_IGNORE`` is now deprecated. Instead, use
one of the add functions in bzrlib.ignores. (John Arbash Meinel)
* 'bzr push' should only push the ancestry of the current revision, not
all of the history in the repository. This is especially important for
shared repositories. (John Arbash Meinel)
* ``bzrlib.delta.compare_trees`` now iterates in alphabetically sorted order,
rather than randomly walking the inventories. (John Arbash Meinel)
* Doctests are now run in temporary directories which are cleaned up when
they finish, rather than using special ScratchDir/ScratchBranch objects.
(Martin Pool)
* Split ``check`` into separate methods on the branch and on the repository,
so that it can be specialized in ways that are useful or efficient for
different formats. (Martin Pool, Robert Collins)
* Deprecate ``Repository.all_revision_ids``; most methods don't really need
the global revision graph but only that part leading up to a particular
revision. (Martin Pool, Robert Collins)
* Add a BzrDirFormat ``control_formats`` list which allows for control formats
that do not use '.bzr' to store their data - i.e. '.svn', '.hg' etc.
(Robert Collins, Jelmer Vernooij).
* ``bzrlib.diff.external_diff`` can be redirected to any file-like object.
Uses subprocess instead of spawnvp.
(James Henstridge, John Arbash Meinel, #4047, #48914)
* New command line option '--profile-imports', which will install a custom
importer to log time to import modules and regex compilation time to
sys.stderr (John Arbash Meinel)
* 'EmptyTree' is now deprecated, please use ``repository.revision_tree(None)``
instead. (Robert Collins)
* "RevisionTree" is now in bzrlib/revisiontree.py. (Robert Collins)
bzr 0.8.2 2006-05-17
---------------------
BUG FIXES:
* setup.py failed to install launchpad plugin. (Martin Pool)
bzr 0.8.1 2006-05-16
---------------------
BUG FIXES:
* Fix failure to commit a merge in a checkout. (Martin Pool,
Robert Collins, Erik BÃ¥gfors, #43959)
* Nicer messages from 'commit' in the case of renames, and correct
messages when a merge has occured. (Robert Collins, Martin Pool)
* Separate functionality from assert statements as they are skipped in
optimized mode of python. Add the same check to pending merges.
(Olaf Conradi, #44443)
CHANGES:
* Do not show the None revision in output of bzr ancestry. (Olaf Conradi)
* Add info on standalone branches without a working tree.
(Olaf Conradi, #44155)
* Fix bug in knits when raising InvalidRevisionId. (Olaf Conradi, #44284)
CHANGES:
* Make editor invocation comply with Debian Policy. First check
environment variables VISUAL and EDITOR, then try editor from
alternatives system. If that all fails, fall back to the pre-defined
list of editors. (Olaf Conradi, #42904)
NEW FEATURES:
* New 'register-branch' command registers a public branch into
Launchpad.net, where it can be associated with bugs, etc.
(Martin Pool, Bjorn Tillenius, Robert Collins)
INTERNALS:
* New public api in InventoryEntry - ``describe_change(old, new)`` which
provides a human description of the changes between two old and
new. (Robert Collins, Martin Pool)
TESTING:
* Fix test case for bzr info in upgrading a standalone branch to metadir,
uses bzrlib api now. (Olaf Conradi)
bzr 0.8 2006-05-08
-------------------
NOTES WHEN UPGRADING:
Release 0.8 of bzr introduces a new format for history storage, called
'knit', as an evolution of to the 'weave' format used in 0.7. Local
and remote operations are faster using knits than weaves. Several
operations including 'init', 'init-repo', and 'upgrade' take a
--format option that controls this. Branching from an existing branch
will keep the same format.
It is possible to merge, pull and push between branches of different
formats but this is slower than moving data between homogenous
branches. It is therefore recommended (but not required) that you
upgrade all branches for a project at the same time. Information on
formats is shown by 'bzr info'.
bzr 0.8 now allows creation of 'repositories', which hold the history
of files and revisions for several branches. Previously bzr kept all
the history for a branch within the .bzr directory at the root of the
branch, and this is still the default. To create a repository, use
the new 'bzr init-repo' command. Branches exist as directories under
the repository and contain just a small amount of information
indicating the current revision of the branch.
bzr 0.8 also supports 'checkouts', which are similar to in cvs and
subversion. Checkouts are associated with a branch (optionally in a
repository), which contains all the historical information. The
result is that a checkout can be deleted without losing any
already-committed revisions. A new 'update' command is also available.
Repositories and checkouts are not supported with the 0.7 storage
format. To use them you must upgrad to either knits, or to the
'metaweave' format, which uses weaves but changes the .bzr directory
arrangement.
IMPROVEMENTS:
* Sftp paths can now be relative, or local, according to the lftp
convention. Paths now take the form::
sftp://user:pass@host:port/~/relative/path
or
sftp://user:pass@host:port/absolute/path
* The FTP transport now tries to reconnect after a temporary
failure. ftp put is made atomic. (Matthieu Moy)
* The FTP transport now maintains a pool of connections, and
reuses them to avoid multiple connections to the same host (like
sftp did). (Daniel Silverstone)
* The ``bzr_man.py`` file has been removed. To create the man page now,
use ``./generate_docs.py man``. The new program can also create other files.
Run ``python generate_docs.py --help`` for usage information.
(Hans Ulrich Niedermann & James Blackwell).
* Man Page now gives full help (James Blackwell).
Help also updated to reflect user config now being stored in .bazaar
(Hans Ulrich Niedermann)
* It's now possible to set aliases in bazaar.conf (Erik BÃ¥gfors)
* Pull now accepts a --revision argument (Erik BÃ¥gfors)
* ``bzr re-sign`` now allows multiple revisions to be supplied on the command
line. You can now use the following command to sign all of your old
commits::
find .bzr/revision-store// -name my@email-* \
| sed 's/.*\/\/..\///' \
| xargs bzr re-sign
* Upgrade can now upgrade over the network. (Robert Collins)
* Two new commands 'bzr checkout' and 'bzr update' allow for CVS/SVN-alike
behaviour. By default they will cache history in the checkout, but
with --lightweight almost all data is kept in the master branch.
(Robert Collins)
* 'revert' unversions newly-versioned files, instead of deleting them.
* 'merge' is more robust. Conflict messages have changed.
* 'merge' and 'revert' no longer clobber existing files that end in '~' or
'.moved'.
* Default log format can be set in configuration and plugins can register
their own formatters. (Erik BÃ¥gfors)
* New 'reconcile' command will check branch consistency and repair indexes
that can become out of sync in pre 0.8 formats. (Robert Collins,
Daniel Silverstone)
* New 'bzr init --format' and 'bzr upgrade --format' option to control
what storage format is created or produced. (Robert Collins,
Martin Pool)
* Add parent location to 'bzr info', if there is one. (Olaf Conradi)
* New developer commands 'weave-list' and 'weave-join'. (Martin Pool)
* New 'init-repository' command, plus support for repositories in 'init'
and 'branch' (Aaron Bentley, Erik BÃ¥gfors, Robert Collins)
* Improve output of 'info' command. Show all relevant locations related to
working tree, branch and repository. Use kibibytes for binary quantities.
Fix off-by-one error in missing revisions of working tree. Make 'info'
work on branches, repositories and remote locations. Show locations
relative to the shared repository, if applicable. Show locking status
of locations. (Olaf Conradi)
* Diff and merge now safely handle binary files. (Aaron Bentley)
* 'pull' and 'push' now normalise the revision history, so that any two
branches with the same tip revision will have the same output from 'log'.
(Robert Collins)
* 'merge' accepts --remember option to store parent location, like 'push'
and 'pull'. (Olaf Conradi)
* bzr status and diff when files given as arguments do not exist
in the relevant trees. (Martin Pool, #3619)
* Add '.hg' to the default ignore list. (Martin Pool)
* 'knit' is now the default disk format. This improves disk performance and
utilization, increases incremental pull performance, robustness with SFTP
and allows checkouts over SFTP to perform acceptably.
The initial Knit code was contributed by Johan Rydberg based on a
specification by Martin Pool.
(Robert Collins, Aaron Bentley, Johan Rydberg, Martin Pool).
* New tool to generate all-in-one html version of the manual. (Alexander
Belchenko)
* Hitting CTRL-C while doing an SFTP push will no longer cause stale locks
to be left in the SFTP repository. (Robert Collins, Martin Pool).
* New option 'diff --prefix' to control how files are named in diff
output, with shortcuts '-p0' and '-p1' corresponding to the options for
GNU patch. (Alexander Belchenko, Goffredo Baroncelli, Martin Pool)
* Add --revision option to 'annotate' command. (Olaf Conradi)
* If bzr shows an unexpected revision-history after pulling (perhaps due
to a reweave) it can now be corrected by 'bzr reconcile'.
(Robert Collins)
CHANGES:
* Commit is now verbose by default, and shows changed filenames and the
new revision number. (Robert Collins, Martin Pool)
* Unify 'mv', 'move', 'rename'. (Matthew Fuller, #5379)
* 'bzr -h' shows help. (Martin Pool, Ian Bicking, #35940)
* Make 'pull' and 'push' remember location on failure using --remember.
(Olaf Conradi)
* For compatibility, make old format for using weaves inside metadir
available as 'metaweave' format. Rename format 'metadir' to 'default'.
Clean up help for option --format in commands 'init', 'init-repo' and
'upgrade'. (Olaf Conradi)
INTERNALS:
* The internal storage of history, and logical branch identity have now
been split into Branch, and Repository. The common locking and file
management routines are now in bzrlib.lockablefiles.
(Aaron Bentley, Robert Collins, Martin Pool)
* Transports can now raise DependencyNotPresent if they need a library
which is not installed, and then another implementation will be
tried. (Martin Pool)
* Remove obsolete (and no-op) `decode` parameter to `Transport.get`.
(Martin Pool)
* Using Tree Transform for merge, revert, tree-building
* WorkingTree.create, Branch.create, ``WorkingTree.create_standalone``,
Branch.initialize are now deprecated. Please see ``BzrDir.create_*`` for
replacement API's. (Robert Collins)
* New BzrDir class represents the .bzr control directory and manages
formatting issues. (Robert Collins)
* New repository.InterRepository class encapsulates Repository to
Repository actions and allows for clean selection of optimised code
paths. (Robert Collins)
* ``bzrlib.fetch.fetch`` and ``bzrlib.fetch.greedy_fetch`` are now
deprecated, please use ``branch.fetch`` or ``repository.fetch``
depending on your needs. (Robert Collins)
* deprecated methods now have a ``is_deprecated`` flag on them that can
be checked, if you need to determine whether a given callable is
deprecated at runtime. (Robert Collins)
* Progress bars are now nested - see
``bzrlib.ui.ui_factory.nested_progress_bar``.
(Robert Collins, Robey Pointer)
* New API call ``get_format_description()`` for each type of format.
(Olaf Conradi)
* Changed ``branch.set_parent()`` to accept None to remove parent.
(Olaf Conradi)
* Deprecated BzrError AmbiguousBase. (Olaf Conradi)
* WorkingTree.branch is now a read only property. (Robert Collins)
* bzrlib.ui.text.TextUIFactory now accepts a ``bar_type`` parameter which
can be None or a factory that will create a progress bar. This is
useful for testing or for overriding the bzrlib.progress heuristic.
(Robert Collins)
* New API method ``get_physical_lock_status()`` to query locks present on a
transport. (Olaf Conradi)
* Repository.reconcile now takes a thorough keyword parameter to allow
requesting an indepth reconciliation, rather than just a data-loss
check. (Robert Collins)
* ``bzrlib.ui.ui_factory protocol`` now supports ``get_boolean`` to prompt
the user for yes/no style input. (Robert Collins)
TESTING:
* SFTP tests now shortcut the SSH negotiation, reducing test overhead
for testing SFTP protocol support. (Robey Pointer)
* Branch formats are now tested once per implementation (see ``bzrlib.
tests.branch_implementations``. This is analagous to the transport
interface tests, and has been followed up with working tree,
repository and BzrDir tests. (Robert Collins)
* New test base class TestCaseWithTransport provides a transport aware
test environment, useful for testing any transport-interface using
code. The test suite option --transport controls the transport used
by this class (when its not being used as part of implementation
contract testing). (Robert Collins)
* Close logging handler on disabling the test log. This will remove the
handler from the internal list inside python's logging module,
preventing shutdown from closing it twice. (Olaf Conradi)
* Move test case for uncommit to blackbox tests. (Olaf Conradi)
* ``run_bzr`` and ``run_bzr_captured`` now accept a 'stdin="foo"'
parameter which will provide String("foo") to the command as its stdin.
bzr 0.7 2006-01-09
------------------
CHANGES:
* .bzrignore is excluded from exports, on the grounds that it's a bzr
internal-use file and may not be wanted. (Jamie Wilkinson)
* The "bzr directories" command were removed in favor of the new
--kind option to the "bzr inventory" command. To list all
versioned directories, now use "bzr inventory --kind directory".
(Johan Rydberg)
* Under Windows configuration directory is now ``%APPDATA%\bazaar\2.0``
by default. (John Arbash Meinel)
* The parent of Bzr configuration directory can be set by ``BZR_HOME``
environment variable. Now the path for it is searched in ``BZR_HOME``,
then in HOME. Under Windows the order is: ``BZR_HOME``, ``APPDATA``
(usually points to ``C:\Documents and Settings\User Name\Application Data``),
``HOME``. (John Arbash Meinel)
* Plugins with the same name in different directories in the bzr plugin
path are no longer loaded: only the first successfully loaded one is
used. (Robert Collins)
* Use systems' external ssh command to open connections if possible.
This gives better integration with user settings such as ProxyCommand.
(James Henstridge)
* Permissions on files underneath .bzr/ are inherited from the .bzr
directory. So for a shared repository, simply doing 'chmod -R g+w .bzr/'
will mean that future file will be created with group write permissions.
* configure.in and config.guess are no longer in the builtin default
ignore list.
* '.sw[nop]' pattern ignored, to ignore vim swap files for nameless
files. (John Arbash Meinel, Martin Pool)
IMPROVEMENTS:
* "bzr INIT dir" now initializes the specified directory, and creates
it if it does not exist. (John Arbash Meinel)
* New remerge command (Aaron Bentley)
* Better zsh completion script. (Steve Borho)
* 'bzr diff' now returns 1 when there are changes in the working
tree. (Robert Collins)
* 'bzr push' now exists and can push changes to a remote location.
This uses the transport infrastructure, and can store the remote
location in the ~/.bazaar/branches.conf configuration file.
(Robert Collins)
* Test directories are only kept if the test fails and the user requests
that they be kept.
* Tweaks to short log printing
* Added branch nicks, new nick command, printing them in log output.
(Aaron Bentley)
* If ``$BZR_PDB`` is set, pop into the debugger when an uncaught exception
occurs. (Martin Pool)
* Accept 'bzr resolved' (an alias for 'bzr resolve'), as this is
the same as Subversion. (Martin Pool)
* New ftp transport support (on ftplib), for ftp:// and aftp://
URLs. (Daniel Silverstone)
* Commit editor temporary files now start with ``bzr_log.``, to allow
text editors to match the file name and set up appropriate modes or
settings. (Magnus Therning)
* Improved performance when integrating changes from a remote weave.
(Goffredo Baroncelli)
* Sftp will attempt to cache the connection, so it is more likely that
a connection will be reused, rather than requiring multiple password
requests.
* bzr revno now takes an optional argument indicating the branch whose
revno should be printed. (Michael Ellerman)
* bzr cat defaults to printing the last version of the file.
(Matthieu Moy, #3632)
* New global option 'bzr --lsprof COMMAND' runs bzr under the lsprof
profiler. (Denys Duchier)
* Faster commits by reading only the headers of affected weave files.
(Denys Duchier)
* 'bzr add' now takes a --dry-run parameter which shows you what would be
added, but doesn't actually add anything. (Michael Ellerman)
* 'bzr add' now lists how many files were ignored per glob. add --verbose
lists the specific files. (Aaron Bentley)
* 'bzr missing' now supports displaying changes in diverged trees and can
be limited to show what either end of the comparison is missing.
(Aaron Bently, with a little prompting from Daniel Silverstone)
BUG FIXES:
* SFTP can walk up to the root path without index errors. (Robert Collins)
* Fix bugs in running bzr with 'python -O'. (Martin Pool)
* Error when run with -OO
* Fix bug in reporting http errors that don't have an http error code.
(Martin Pool)
* Handle more cases of pipe errors in display commands
* Change status to 3 for all errors
* Files that are added and unlinked before committing are completely
ignored by diff and status
* Stores with some compressed texts and some uncompressed texts are now
able to be used. (John A Meinel)
* Fix for bzr pull failing sometimes under windows
* Fix for sftp transport under windows when using interactive auth
* Show files which are both renamed and modified as such in 'bzr
status' output. (Daniel Silverstone, #4503)
* Make annotate cope better with revisions committed without a valid
email address. (Marien Zwart)
* Fix representation of tab characters in commit messages.
(Harald Meland)
* List of plugin directories in ``BZR_PLUGIN_PATH`` environment variable is
now parsed properly under Windows. (Alexander Belchenko)
* Show number of revisions pushed/pulled/merged. (Robey Pointer)
* Keep a cached copy of the basis inventory to speed up operations
that need to refer to it. (Johan Rydberg, Martin Pool)
* Fix bugs in bzr status display of non-ascii characters.
(Martin Pool)
* Remove Makefile.in from default ignore list.
(Tollef Fog Heen, Martin Pool, #6413)
* Fix failure in 'bzr added'. (Nathan McCallum, Martin Pool)
TESTING:
* Fix selftest asking for passwords when there are no SFTP keys.
(Robey Pointer, Jelmer Vernooij)
* Fix selftest run with 'python -O'. (Martin Pool)
* Fix HTTP tests under Windows. (John Arbash Meinel)
* Make tests work even if HOME is not set (Aaron Bentley)
* Updated ``build_tree`` to use fixed line-endings for tests which read
the file cotents and compare. Make some tests use this to pass under
Windows. (John Arbash Meinel)
* Skip stat and symlink tests under Windows. (Alexander Belchenko)
* Delay in selftest/testhashcash is now issued under win32 and Cygwin.
(John Arbash Meinel)
* Use terminal width to align verbose test output. (Martin Pool)
* Blackbox tests are maintained within the bzrlib.tests.blackbox directory.
If adding a new test script please add that to
``bzrlib.tests.blackbox.__init__``. (Robert Collins)
* Much better error message if one of the test suites can't be
imported. (Martin Pool)
* Make check now runs the test suite twice - once with the default locale,
and once with all locales forced to C, to expose bugs. This is not
trivially done within python, so for now its only triggered by running
Make check. Integrators and packagers who wish to check for full
platform support should run 'make check' to test the source.
(Robert Collins)
* Tests can now run TestSkipped if they can't execute for any reason.
(Martin Pool) (NB: TestSkipped should only be raised for correctable
reasons - see the wiki spec ImprovingBzrTestSuite).
* Test sftp with relative, absolute-in-homedir and absolute-not-in-homedir
paths for the transport tests. Introduce blackbox remote sftp tests that
test the same permutations. (Robert Collins, Robey Pointer)
* Transport implementation tests are now independent of the local file
system, which allows tests for esoteric transports, and for features
not available in the local file system. They also repeat for variations
on the URL scheme that can introduce issues in the transport code,
see bzrlib.transport.TransportTestProviderAdapter() for this.
(Robert Collins).
* ``TestCase.build_tree`` uses the transport interface to build trees,
pass in a transport parameter to give it an existing connection.
(Robert Collins).
INTERNALS:
* WorkingTree.pull has been split across Branch and WorkingTree,
to allow Branch only pulls. (Robert Collins)
* ``commands.display_command`` now returns the result of the decorated
function. (Robert Collins)
* LocationConfig now has a ``set_user_option(key, value)`` call to save
a setting in its matching location section (a new one is created
if needed). (Robert Collins)
* Branch has two new methods, ``get_push_location`` and
``set_push_location`` to respectively, get and set the push location.
(Robert Collins)
* ``commands.register_command`` now takes an optional flag to signal that
the registrant is planning to decorate an existing command. When
given multiple plugins registering a command is not an error, and
the original command class (whether built in or a plugin based one) is
returned to the caller. There is a new error 'MustUseDecorated' for
signalling when a wrapping command should switch to the original
version. (Robert Collins)
* Some option parsing errors will raise 'BzrOptionError', allowing
granular detection for decorating commands. (Robert Collins).
* ``Branch.read_working_inventory`` has moved to
``WorkingTree.read_working_inventory``. This necessitated changes to
``Branch.get_root_id``, and a move of ``Branch.set_inventory`` to
WorkingTree as well. To make it clear that a WorkingTree cannot always
be obtained ``Branch.working_tree()`` will raise
``errors.NoWorkingTree`` if one cannot be obtained. (Robert Collins)
* All pending merges operations from Branch are now on WorkingTree.
(Robert Collins)
* The follow operations from Branch have moved to WorkingTree::
add()
commit()
move()
rename_one()
unknowns()
(Robert Collins)
* ``bzrlib.add.smart_add_branch`` is now ``smart_add_tree``. (Robert Collins)
* New "rio" serialization format, similar to rfc-822. (Martin Pool)
* Rename selftests to ``bzrlib.tests.test_foo``. (John A Meinel, Martin
Pool)
* ``bzrlib.plugin.all_plugins`` has been changed from an attribute to a
query method. (Robert Collins)
* New options to read only the table-of-contents of a weave.
(Denys Duchier)
* Raise NoSuchFile when someone tries to add a non-existant file.
(Michael Ellerman)
* Simplify handling of DivergedBranches in ``cmd_pull()``.
(Michael Ellerman)
* Branch.controlfile* logic has moved to lockablefiles.LockableFiles, which
is exposed as ``Branch().control_files``. Also this has been altered with the
controlfile pre/suffix replaced by simple method names like 'get' and
'put'. (Aaron Bentley, Robert Collins).
* Deprecated functions and methods can now be marked as such using the
``bzrlib.symbol_versioning`` module. Marked method have their docstring
updated and will issue a DeprecationWarning using the warnings module
when they are used. (Robert Collins)
* ``bzrlib.osutils.safe_unicode`` now exists to provide parameter coercion
for functions that need unicode strings. (Robert Collins)
bzr 0.6 2005-10-28
------------------
IMPROVEMENTS:
* pull now takes --verbose to show you what revisions are added or removed
(John A Meinel)
* merge now takes a --show-base option to include the base text in
conflicts.
(Aaron Bentley)
* The config files are now read using ConfigObj, so '=' should be used as
a separator, not ':'.
(Aaron Bentley)
* New 'bzr commit --strict' option refuses to commit if there are
any unknown files in the tree. To commit, make sure all files are
either ignored, added, or deleted. (Michael Ellerman)
* The config directory is now ~/.bazaar, and there is a single file
~/.bazaar/bazaar.conf storing email, editor and other preferences.
(Robert Collins)
* 'bzr add' no longer takes a --verbose option, and a --quiet option
has been added that suppresses all output.
* Improved zsh completion support in contrib/zsh, from Clint
Adams.
* Builtin 'bzr annotate' command, by Martin Pool with improvements from
Goffredo Baroncelli.
* 'bzr check' now accepts -v for verbose reporting, and checks for
ghosts in the branch. (Robert Collins)
* New command 're-sign' which will regenerate the gpg signature for
a revision. (Robert Collins)
* If you set ``check_signatures=require`` for a path in
``~/.bazaar/branches.conf`` then bzr will invoke your
``gpg_signing_command`` (defaults to gpg) and record a digital signature
of your commit. (Robert Collins)
* New sftp transport, based on Paramiko. (Robey Pointer)
* 'bzr pull' now accepts '--clobber' which will discard local changes
and make this branch identical to the source branch. (Robert Collins)
* Just give a quieter warning if a plugin can't be loaded, and
put the details in .bzr.log. (Martin Pool)
* 'bzr branch' will now set the branch-name to the last component of the
output directory, if one was supplied.
* If the option ``post_commit`` is set to one (or more) python function
names (must be in the bzrlib namespace), then they will be invoked
after the commit has completed, with the branch and ``revision_id`` as
parameters. (Robert Collins)
* Merge now has a retcode of 1 when conflicts occur. (Robert Collins)
* --merge-type weave is now supported for file contents. Tree-shape
changes are still three-way based. (Martin Pool, Aaron Bentley)
* 'bzr check' allows the first revision on revision-history to have
parents - something that is expected for cheap checkouts, and occurs
when conversions from baz do not have all history. (Robert Collins).
* 'bzr merge' can now graft unrelated trees together, if your specify
0 as a base. (Aaron Bentley)
* 'bzr commit branch' and 'bzr commit branch/file1 branch/file2' now work
(Aaron Bentley)
* Add '.sconsign*' to default ignore list. (Alexander Belchenko)
* 'bzr merge --reprocess' minimizes conflicts
TESTING:
* The 'bzr selftest --pattern' option for has been removed, now
test specifiers on the command line can be simple strings, or
regexps, or both. (Robert Collins)
* Passing -v to selftest will now show the time each test took to
complete, which will aid in analysing performance regressions and
related questions. (Robert Collins)
* 'bzr selftest' runs all tests, even if one fails, unless '--one'
is given. (Martin Pool)
* There is a new method for TestCaseInTempDir, assertFileEqual, which
will check that a given content is equal to the content of the named
file. (Robert Collins)
* Fix test suite's habit of leaving many temporary log files in $TMPDIR.
(Martin Pool)
INTERNALS:
* New 'testament' command and concept for making gpg-signatures
of revisions that are not tied to a particular internal
representation. (Martin Pool).
* Per-revision properties ('revprops') as key-value associated
strings on each revision created when the revision is committed.
Intended mainly for the use of external tools. (Martin Pool).
* Config options have moved from bzrlib.osutils to bzrlib.config.
(Robert Collins)
* Improved command line option definitions allowing explanations
for individual options, among other things. Contributed by
Magnus Therning.
* Config options have moved from bzrlib.osutils to bzrlib.config.
Configuration is now done via the config.Config interface:
Depending on whether you have a Branch, a Location or no information
available, construct a ``*Config``, and use its ``signature_checking``,
``username`` and ``user_email`` methods. (Robert Collins)
* Plugins are now loaded under bzrlib.plugins, not bzrlib.plugin, and
they are made available for other plugins to use. You should not
import other plugins during the ``__init__`` of your plugin though, as
no ordering is guaranteed, and the plugins directory is not on the
python path. (Robert Collins)
* Branch.relpath has been moved to WorkingTree.relpath. WorkingTree no
no longer takes an inventory, rather it takes an option branch
parameter, and if None is given will open the branch at basedir
implicitly. (Robert Collins)
* Cleaner exception structure and error reporting. Suggested by
Scott James Remnant. (Martin Pool)
* Branch.remove has been moved to WorkingTree, which has also gained
``lock_read``, ``lock_write`` and ``unlock`` methods for convenience.
(Robert Collins)
* Two decorators, ``needs_read_lock`` and ``needs_write_lock`` have been
added to the branch module. Use these to cause a function to run in a
read or write lock respectively. (Robert Collins)
* ``Branch.open_containing`` now returns a tuple (Branch, relative-path),
which allows direct access to the common case of 'get me this file
from its branch'. (Robert Collins)
* Transports can register using ``register_lazy_transport``, and they
will be loaded when first used. (Martin Pool)
* 'pull' has been factored out of the command as ``WorkingTree.pull()``.
A new option to WorkingTree.pull has been added, clobber, which will
ignore diverged history and pull anyway.
(Robert Collins)
* config.Config has a ``get_user_option`` call that accepts an option name.
This will be looked up in branches.conf and bazaar.conf as normal.
It is intended that this be used by plugins to support options -
options of built in programs should have specific methods on the config.
(Robert Collins)
* ``merge.merge_inner`` now has tempdir as an optional parameter.
(Robert Collins)
* Tree.kind is not recorded at the top level of the hierarchy, as it was
missing on EmptyTree, leading to a bug with merge on EmptyTrees.
(Robert Collins)
* ``WorkingTree.__del__`` has been removed, it was non deterministic and not
doing what it was intended to. See ``WorkingTree.__init__`` for a comment
about future directions. (Robert Collins/Martin Pool)
* bzrlib.transport.http has been modified so that only 404 urllib errors
are returned as NoSuchFile. Other exceptions will propogate as normal.
This allows debuging of actual errors. (Robert Collins)
* bzrlib.transport.Transport now accepts *ONLY* url escaped relative paths
to apis like 'put', 'get' and 'has'. This is to provide consistent
behaviour - it operates on url's only. (Robert Collins)
* Transports can register using ``register_lazy_transport``, and they
will be loaded when first used. (Martin Pool)
* ``merge_flex`` no longer calls ``conflict_handler.finalize()``, instead that
is called by ``merge_inner``. This is so that the conflict count can be
retrieved (and potentially manipulated) before returning to the caller
of ``merge_inner``. Likewise 'merge' now returns the conflict count to the
caller. (Robert Collins)
* ``revision.revision_graph`` can handle having only partial history for
a revision - that is no revisions in the graph with no parents.
(Robert Collins).
* New ``builtins.branch_files`` uses the standard ``file_list`` rules to
produce a branch and a list of paths, relative to that branch
(Aaron Bentley)
* New TestCase.addCleanup facility.
* New ``bzrlib.version_info`` tuple (similar to ``sys.version_info``),
which can be used by programs importing bzrlib.
BUG FIXES:
* Better handling of branches in directories with non-ascii names.
(Joel Rosdahl, Panagiotis Papadakos)
* Upgrades of trees with no commits will not fail due to accessing
[-1] in the revision-history. (Andres Salomon)
bzr 0.1.1 2005-10-12
--------------------
BUG FIXES:
* Fix problem in pulling over http from machines that do not
allow directories to be listed.
* Avoid harmless warning about invalid hash cache after
upgrading branch format.
PERFORMANCE:
* Avoid some unnecessary http operations in branch and pull.
bzr 0.1 2005-10-11
------------------
NOTES:
* 'bzr branch' over http initially gives a very high estimate
of completion time but it should fall as the first few
revisions are pulled in. branch is still slow on
high-latency connections.
BUG FIXES:
* bzr-man.py has been updated to work again. Contributed by
Rob Weir.
* Locking is now done with fcntl.lockf which works with NFS
file systems. Contributed by Harald Meland.
* When a merge encounters a file that has been deleted on
one side and modified on the other, the old contents are
written out to foo.BASE and foo.SIDE, where SIDE is this
or OTHER. Contributed by Aaron Bentley.
* Export was choosing incorrect file paths for the content of
the tarball, this has been fixed by Aaron Bentley.
* Commit will no longer commit without a log message, an
error is returned instead. Contributed by Jelmer Vernooij.
* If you commit a specific file in a sub directory, any of its
parent directories that are added but not listed will be
automatically included. Suggested by Michael Ellerman.
* bzr commit and upgrade did not correctly record new revisions
for files with only a change to their executable status.
bzr will correct this when it encounters it. Fixed by
Robert Collins
* HTTP tests now force off the use of ``http_proxy`` for the duration.
Contributed by Gustavo Niemeyer.
* Fix problems in merging weave-based branches that have
different partial views of history.
* Symlink support: working with symlinks when not in the root of a
bzr tree was broken, patch from Scott James Remnant.
IMPROVEMENTS:
* 'branch' now accepts a --basis parameter which will take advantage
of local history when making a new branch. This allows faster
branching of remote branches. Contributed by Aaron Bentley.
* New tree format based on weave files, called version 5.
Existing branches can be upgraded to this format using
'bzr upgrade'.
* Symlinks are now versionable. Initial patch by
Erik Toubro Nielsen, updated to head by Robert Collins.
* Executable bits are tracked on files. Patch from Gustavo
Niemeyer.
* 'bzr status' now shows unknown files inside a selected directory.
Patch from Heikki Paajanen.
* Merge conflicts are recorded in .bzr. Two new commands 'conflicts'
and 'resolve' have needed added, which list and remove those
merge conflicts respectively. A conflicted tree cannot be committed
in. Contributed by Aaron Bentley.
* 'rm' is now an alias for 'remove'.
* Stores now split out their content in a single byte prefixed hash,
dropping the density of files per directory by 256. Contributed by
Gustavo Niemeyer.
* 'bzr diff -r branch:URL' will now perform a diff between two branches.
Contributed by Robert Collins.
* 'bzr log' with the default formatter will show merged revisions,
indented to the right. Initial implementation contributed by Gustavo
Niemeyer, made incremental by Robert Collins.
INTERNALS:
* Test case failures have the exception printed after the log
for your viewing pleasure.
* InventoryEntry is now an abstract base class, use one of the
concrete InventoryDirectory etc classes instead.
* Branch raises an UnsupportedFormatError when it detects a
bzr branch it cannot understand. This allows for precise
handling of such circumstances.
* Remove RevisionReference class; ``Revision.parent_ids`` is now simply a
list of their ids and ``parent_sha1s`` is a list of their corresponding
sha1s (for old branches only at the moment.)
* New method-object style interface for Commit() and Fetch().
* Renamed ``Branch.last_patch()`` to ``Branch.last_revision()``, since
we call them revisions not patches.
* Move ``copy_branch`` to ``bzrlib.clone.copy_branch``. The destination
directory is created if it doesn't exist.
* Inventories now identify the files which were present by
giving the revision *of that file*.
* Inventory and Revision XML contains a version identifier.
This must be consistent with the overall branch version
but allows for more flexibility in future upgrades.
TESTING:
* Removed testsweet module so that tests can be run after
bzr installed by 'bzr selftest'.
* 'bzr selftest' command-line arguments can now be partial ids
of tests to run, e.g. ``bzr selftest test_weave``
bzr 0.0.9 2005-09-23
--------------------
BUG FIXES:
* Fixed "branch -r" option.
* Fix remote access to branches containing non-compressed history.
(Robert Collins).
* Better reliability of http server tests. (John Arbash-Meinel)
* Merge graph maximum distance calculation fix. (Aaron Bentley)
* Various minor bug in windows support have been fixed, largely in the
test suite. Contributed by Alexander Belchenko.
IMPROVEMENTS:
* Status now accepts a -r argument to give status between chosen
revisions. Contributed by Heikki Paajanen.
* Revision arguments no longer use +/-/= to control ranges, instead
there is a 'before' namespace, which limits the successive namespace.
For example '$ bzr log -r date:yesterday..before:date:today' will
select everything from yesterday and before today. Contributed by
Robey Pointer
* There is now a bzr.bat file created by distutils when building on
Windows. Contributed by Alexander Belchenko.
INTERNALS:
* Removed uuid() as it was unused.
* Improved 'fetch' code for pulling revisions from one branch into
another (used by pull, merged, etc.)
bzr 0.0.8 2005-09-20
--------------------
IMPROVEMENTS:
* Adding a file whose parent directory is not versioned will
implicitly add the parent, and so on up to the root. This means
you should never need to explictly add a directory, they'll just
get added when you add a file in the directory. Contributed by
Michael Ellerman.
* Ignore ``.DS_Store`` (contains Mac metadata) by default.
(Nir Soffer)
* If you set ``BZR_EDITOR`` in the environment, it is checked in
preference to EDITOR and the config file for the interactive commit
editing program. Related to this is a bugfix where a missing program
set in EDITOR would cause editing to fail, now the fallback program
for the operating system is still tried.
* Files that are not directories/symlinks/regular files will no longer
cause bzr to fail, it will just ignore them by default. You cannot add
them to the tree though - they are not versionable.
INTERNALS:
* Refactor xml packing/unpacking.
BUG FIXES:
* Fixed 'bzr mv' by Ollie Rutherfurd.
* Fixed strange error when trying to access a nonexistent http
branch.
* Make sure that the hashcache gets written out if it can't be
read.
PORTABILITY:
* Various Windows fixes from Ollie Rutherfurd.
* Quieten warnings about locking; patch from Matt Lavin.
bzr-0.0.7 2005-09-02
--------------------
NEW FEATURES:
* ``bzr shell-complete`` command contributed by Clint Adams to
help with intelligent shell completion.
* New expert command ``bzr find-merge-base`` for debugging merges.
ENHANCEMENTS:
* Much better merge support.
* merge3 conflicts are now reported with markers like '<<<<<<<'
(seven characters) which is the same as CVS and pleases things
like emacs smerge.
BUG FIXES:
* ``bzr upgrade`` no longer fails when trying to fix trees that
mention revisions that are not present.
* Fixed bugs in listing plugins from ``bzr plugins``.
* Fix case of $EDITOR containing options for the editor.
* Fix log -r refusing to show the last revision.
(Patch from Goffredo Baroncelli.)
CHANGES:
* ``bzr log --show-ids`` shows the revision ids of all parents.
* Externally provided commands on your $BZRPATH no longer need
to recognize --bzr-usage to work properly, and can just handle
--help themselves.
LIBRARY:
* Changed trace messages to go through the standard logging
framework, so that they can more easily be redirected by
libraries.
bzr-0.0.6 2005-08-18
--------------------
NEW FEATURES:
* Python plugins, automatically loaded from the directories on
``BZR_PLUGIN_PATH`` or ``~/.bzr.conf/plugins`` by default.
* New 'bzr mkdir' command.
* Commit mesage is fetched from an editor if not given on the
command line; patch from Torsten Marek.
* ``bzr log -m FOO`` displays commits whose message matches regexp
FOO.
* ``bzr add`` with no arguments adds everything under the current directory.
* ``bzr mv`` does move or rename depending on its arguments, like
the Unix command.
* ``bzr missing`` command shows a summary of the differences
between two trees. (Merged from John Arbash-Meinel.)
* An email address for commits to a particular tree can be
specified by putting it into .bzr/email within a branch. (Based
on a patch from Heikki Paajanen.)
ENHANCEMENTS:
* Faster working tree operations.
CHANGES:
* 3rd-party modules shipped with bzr are copied within the bzrlib
python package, so that they can be installed by the setup
script without clashing with anything already existing on the
system. (Contributed by Gustavo Niemeyer.)
* Moved plugins directory to bzrlib/, so that there's a standard
plugin directory which is not only installed with bzr itself but
is also available when using bzr from the development tree.
``BZR_PLUGIN_PATH`` and ``DEFAULT_PLUGIN_PATH`` are then added to the
standard plugins directory.
* When exporting to a tarball with ``bzr export --format tgz``, put
everything under a top directory rather than dumping it into the
current directory. This can be overridden with the ``--root``
option. Patch from William Dodé and John Meinel.
* New ``bzr upgrade`` command to upgrade the format of a branch,
replacing ``bzr check --update``.
* Files within store directories are no longer marked readonly on
disk.
* Changed ``bzr log`` output to a more compact form suggested by
John A Meinel. Old format is available with the ``--long`` or
``-l`` option, patched by William Dodé.
* By default the commit command refuses to record a revision with
no changes unless the ``--unchanged`` option is given.
* The ``--no-plugins``, ``--profile`` and ``--builtin`` command
line options must come before the command name because they
affect what commands are available; all other options must come
after the command name because their interpretation depends on
it.
* ``branch`` and ``clone`` added as aliases for ``branch``.
* Default log format is back to the long format; the compact one
is available with ``--short``.
BUG FIXES:
* Fix bugs in committing only selected files or within a subdirectory.
bzr-0.0.5 2005-06-15
---------------------
CHANGES:
* ``bzr`` with no command now shows help rather than giving an
error. Suggested by Michael Ellerman.
* ``bzr status`` output format changed, because svn-style output
doesn't really match the model of bzr. Now files are grouped by
status and can be shown with their IDs. ``bzr status --all``
shows all versioned files and unknown files but not ignored files.
* ``bzr log`` runs from most-recent to least-recent, the reverse
of the previous order. The previous behaviour can be obtained
with the ``--forward`` option.
* ``bzr inventory`` by default shows only filenames, and also ids
if ``--show-ids`` is given, in which case the id is the second
field.
ENHANCEMENTS:
* New 'bzr whoami --email' option shows only the email component
of the user identification, from Jo Vermeulen.
* New ``bzr ignore PATTERN`` command.
* Nicer error message for broken pipe, interrupt and similar
conditions that don't indicate an internal error.
* Add ``.*.sw[nop] .git .*.tmp *,v`` to default ignore patterns.
* Per-branch locks keyed on ``.bzr/branch-lock``, available in
either read or write mode.
* New option ``bzr log --show-ids`` shows revision and file ids.
* New usage ``bzr log FILENAME`` shows only revisions that
affected that file.
* Changed format for describing changes in ``bzr log -v``.
* New option ``bzr commit --file`` to take a message from a file,
suggested by LarstiQ.
* New syntax ``bzr status [FILE...]`` contributed by Bartosz
Oler. File may be in a branch other than the working directory.
* ``bzr log`` and ``bzr root`` can be given an http URL instead of
a filename.
* Commands can now be defined by external programs or scripts
in a directory on $BZRPATH.
* New "stat cache" avoids reading the contents of files if they
haven't changed since the previous time.
* If the Python interpreter is too old, try to find a better one
or give an error. Based on a patch from Fredrik Lundh.
* New optional parameter ``bzr info [BRANCH]``.
* New form ``bzr commit SELECTED`` to commit only selected files.
* New form ``bzr log -r FROM:TO`` shows changes in selected
range; contributed by John A Meinel.
* New option ``bzr diff --diff-options 'OPTS'`` allows passing
options through to an external GNU diff.
* New option ``bzr add --no-recurse`` to add a directory but not
their contents.
* ``bzr --version`` now shows more information if bzr is being run
from a branch.
BUG FIXES:
* Fixed diff format so that added and removed files will be
handled properly by patch. Fix from Lalo Martins.
* Various fixes for files whose names contain spaces or other
metacharacters.
TESTING:
* Converted black-box test suites from Bourne shell into Python;
now run using ``./testbzr``. Various structural improvements to
the tests.
* testbzr by default runs the version of bzr found in the same
directory as the tests, or the one given as the first parameter.
* testbzr also runs the internal tests, so the only command
required to check is just ``./testbzr``.
* testbzr requires python2.4, but can be used to test bzr running
under a different version.
* Tests added for many other changes in this release.
INTERNAL:
* Included ElementTree library upgraded to 1.2.6 by Fredrik Lundh.
* Refactor command functions into Command objects based on HCT by
Scott James Remnant.
* Better help messages for many commands.
* Expose ``bzrlib.open_tracefile()`` to start the tracefile; until
this is called trace messages are just discarded.
* New internal function ``find_touching_revisions()`` and hidden
command touching-revisions trace the changes to a given file.
* Simpler and faster ``compare_inventories()`` function.
* ``bzrlib.open_tracefile()`` takes a tracefilename parameter.
* New AtomicFile class.
* New developer commands ``added``, ``modified``.
PORTABILITY:
* Cope on Windows on python2.3 by using the weaker random seed.
2.4 is now only recommended.
bzr-0.0.4 2005-04-22
---------------------
ENHANCEMENTS:
* 'bzr diff' optionally takes a list of files to diff. Still a bit
basic. Patch from QuantumG.
* More default ignore patterns.
* New 'bzr log --verbose' shows a list of files changed in the
changeset. Patch from Sebastian Cote.
* Roll over ~/.bzr.log if it gets too large.
* Command abbreviations 'ci', 'st', 'stat', '?' based on a patch
by Jason Diamon.
* New 'bzr help commands' based on a patch from Denys Duchier.
CHANGES:
* User email is determined by looking at $BZREMAIL or ~/.bzr.email
or $EMAIL. All are decoded by the locale preferred encoding.
If none of these are present user@hostname is used. The host's
fully-qualified name is not used because that tends to fail when
there are DNS problems.
* New 'bzr whoami' command instead of username user-email.
BUG FIXES:
* Make commit safe for hardlinked bzr trees.
* Some Unicode/locale fixes.
* Partial workaround for ``difflib.unified_diff`` not handling
trailing newlines properly.
INTERNAL:
* Allow docstrings for help to be in PEP0257 format. Patch from
Matt Brubeck.
* More tests in test.sh.
* Write profile data to a temporary file not into working
directory and delete it when done.
* Smaller .bzr.log with process ids.
PORTABILITY:
* Fix opening of ~/.bzr.log on Windows. Patch from Andrew
Bennetts.
* Some improvements in handling paths on Windows, based on a patch
from QuantumG.
bzr-0.0.3 2005-04-06
---------------------
ENHANCEMENTS:
* New "directories" internal command lists versioned directories
in the tree.
* Can now say "bzr commit --help".
* New "rename" command to rename one file to a different name
and/or directory.
* New "move" command to move one or more files into a different
directory.
* New "renames" command lists files renamed since base revision.
* New cat command contributed by janmar.
CHANGES:
* .bzr.log is placed in $HOME (not pwd) and is always written in
UTF-8. (Probably not a completely good long-term solution, but
will do for now.)
PORTABILITY:
* Workaround for difflib bug in Python 2.3 that causes an
exception when comparing empty files. Reported by Erik Toubro
Nielsen.
INTERNAL:
* Refactored inventory storage to insert a root entry at the top.
TESTING:
* Start of shell-based black-box testing in test.sh.
bzr-0.0.2.1
-----------
PORTABILITY:
* Win32 fixes from Steve Brown.
bzr-0.0.2 "black cube" 2005-03-31
-----------------------------------
ENHANCEMENTS:
* Default ignore list extended (see bzrlib/__init__.py).
* Patterns in .bzrignore are now added to the default ignore list,
rather than replacing it.
* Ignore list isn't reread for every file.
* More help topics.
* Reinstate the 'bzr check' command to check invariants of the
branch.
* New 'ignored' command lists which files are ignored and why;
'deleted' lists files deleted in the current working tree.
* Performance improvements.
* New global --profile option.
* Ignore patterns like './config.h' now correctly match files in
the root directory only.
bzr-0.0.1 2005-03-26
---------------------
ENHANCEMENTS:
* More information from info command.
* Can now say "bzr help COMMAND" for more detailed help.
* Less file flushing and faster performance when writing logs and
committing to stores.
* More useful verbose output from some commands.
BUG FIXES:
* Fix inverted display of 'R' and 'M' during 'commit -v'.
PORTABILITY:
* Include a subset of ElementTree-1.2.20040618 to make
installation easier.
* Fix time.localtime call to work with Python 2.3 (the minimum
supported).
bzr-0.0.0.69 2005-03-22
------------------------
ENHANCEMENTS:
* First public release.
* Storage of local versions: init, add, remove, rm, info, log,
diff, status, etc.
