bzr 0.11rc1
###########
:Released: 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, #43744)
* 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, #56815)
* 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)
