bzr 2.5.2

#########

:2.5.2: NOT RELEASED YET

External Compatibility Breaks

*****************************

.. These may require users to change the way they use Bazaar.

New Features

************

.. New commands, options, etc that users may wish to try out.

Improvements

************

.. Improvements to existing commands, especially improved performance 

   or memory usage, or better results.

Bug Fixes

*********

.. Fixes for situations where bzr would previously crash or give incorrect

   or undesirable results.

* ``bzr config`` properly handles aliases and references in the

  ``--directory`` parameter (Vincent Ladeuil, Wouter van Heyst, #947049)

* Empty arguments in EDITOR are now properly preserved.

  (Ross Lagerwall, #1089792)

* Fix a traceback when trying to checkout a tree that also has an entry

  with file-id `TREE_ROOT` somewhere other than at the root directory.

  (John Arbash Meinel, #830947)

* Lightweight checkouts of remote repositories had a bug with how they

  extracted texts from the repository. (Just an ordering constraint on how

  they consumed the stream.) (John Arbash Meinel, #1046284)

* ``osutils.send_all`` now detects if we get a series of zero bytes sent,

  and fails with a ECONNRESET. It seems if paramiko gets disconnected, it

  will get into a state where it returns 0 bytes sent, but doesn't raise

  an error. This change allows us to get a couple hiccups of no content

  sent, but if it is consistent, we will consider it to be a failure.

  (John Arbash Meinel, #1047309)

* Revert use of --no-tty when gpg signing commits. (Jelmer Vernooij, #1014570)

* Some filesystems give ``EOPNOTSUPP`` when trying to call ``fdatasync``.

  This shouldn't be treated as a fatal error.

  (John Arbash Meinel, #1075108)

* Some small bug fixes wrt lightweight checkouts and remote repositories.

  A test permutation was added that runs all working tree tests against a

  lightweight checkout. (John Arbash Meinel, #1046697)

Documentation

*************

.. Improved or updated documentation.

API Changes

***********

.. Changes that may require updates in plugins or other code that uses

   bzrlib.

Internals

*********

.. Major internal changes, unlikely to be visible to users or plugin 

   developers, but interesting for bzr developers.

Testing

*******

.. Fixes and changes that are only relevant to bzr's test framework and 

   suite.  This can include new facilities for writing tests, fixes to 

   spurious test failures and changes to the way things should be tested.

bzr 2.5.1

#########

:2.5.1: 2012-05-22

This is a bugfix release. Most of the bugs dealt with https and colocated

branches glitches. Upgrading is recommended for all users of earlier 2.5

releases.

External Compatibility Breaks

*****************************

None.

New Features

************

None.

Improvements

************

* ``bzr rmbranch`` now supports removing colocated branches.

  (Jelmer Vernooij, #920653)

* ``bzr rmbranch`` no longer removes active branches unless ``--force``

  is specified. (Jelmer Vernooij, #922953)

Bug Fixes

*********

* Connecting with HTTPS via HTTP now correctly uses the host name of the

  destination rather than the proxy when checking certificates.

  (Martin Packman, #944696)

* Fixed merge tool availability checking and invocation to search the

  Windows App Path registry in addition to the PATH. (Gordon Tyler, #939605)

* Fixed problem with getting errors about failing to open /dev/tty when using

  Bazaar Explorer to sign commits. (Mark Grandi, #847388)

* Fix UnicodeEncodeError when translated progress task messages contain

  non-ascii text. (Martin Packman, #966934)

* Make sure configuration options can provide their own help topic.

  (Jelmer Vernooij, #941672)

Documentation

*************

* The alpha-quality texinfo sphinx builder has been deprecated. Sphinx >=

  1.1.2 now provides a better one. Most of the documentation can now be

  generated to the texinfo format with ``make texinfo-sphinx``. This will

  generate both the ``.texi`` files and the ``.info`` ones.

  (Vincent Ladeuil, #940164)

API Changes

***********

None.

Testing

*******

* Add support for pyftpdlib >= 0.7.0 and drop support for previous pyftpdlib

  versions. (Vincent Ladeuil, #956027)

* Run smoketest for setup.py isolated in a tempdir. (Martin Packman, #140874)

bzr 2.5.0

#########

:Codename: Phillip

:2.5.0: 2012-02-24

This release marks the start of a new long-term-stable series. From here, we

will only make bugfix releases on the 2.5 series (2.5.1, etc, and support it

until April 2017), while 2.6 will become our new development series.

This is a bugfix and polish release over the 2.4 series, with a large number

of bugs fixed (~170 for the 2.5 series alone). The 2.5 series provides a

faster smart protocol implementation for many operations, basic support for

colocated branches. We have started translating bzr with the 2.5 series:

https://translations.launchpad.net/bzr, more than 20 languages have already

been registered but these are the early days, contributions welcome.

Only a few bugfixes have been included since 2.5b6 so all known fixed bugs

are included here.

Users are encouraged to upgrade from the other stable series.

External Compatibility Breaks

*****************************

None.

New Features

************

None.

Improvements

************

* The names of colocated branches are used as branch nicks if no nick is

  specified. (Aaron Bentley)

Bug Fixes

*********

* Show locks in ``bzr info`` on control directories without a

  repository. (Jelmer Vernooij, #936767)

* Disable ssl certificate verification on osx and windows until a native

  access to the the root certificates is provided there.

  (Vincent Ladeuil, #929179)

Testing

*******

* Stop depending on the particular CPython ordering of dictionary keys

  when testing the result of BzrDir.get_branches.

  (Wouter van Heyst)

bzr 2.5b6

#########

:2.5b6: 2012-02-02

This is the sixth (and last (really)) beta of the 2.5 series, leading to a

2.5.0 release in March 2012. Beta releases are suitable for everyday use

but may cause some incompatibilities with plugins.

This introduces the support for colocated branches into the '2a' format in a

backward compatible way, fix more glitches in the colocated UI, verify https

certificates for the urllib https client implementation, fix some more

unicode issues and more.

All bugs fixed in previous series known at the time of this release are

included.

External Compatibility Breaks

*****************************

None.

New Features

************

* Support for colocated branches is now available in the default

  format ("2a"). (Jelmer Vernooij)

Improvements

************

* ``bzr switch -b`` in a standalone tree will now create a colocated branch.

  (Jelmer Vernooij, #918197)

* ``bzr info`` now reports when there are present (but unused) colocated

  branches. (Jelmer Vernooij, #891646)

* Checkouts can now be into target directories that already have

  a control directory (but no branch or working tree).

  (Jelmer Vernooij, #913980)

* Colocated branches can now have names including forward slashes, to

  allow for namespaces. (Jelmer Vernooij, #907980)

* New HPSS call for ``BzrDir.get_branches``. (Jelmer Vernooij, #894460)

* Checkouts of colocated branches are now always lightweight.

  (Jelmer Vernooij, #918828)

Bug Fixes

*********

* ``bzr branch`` now fetches revisions when branching into an empty

  control directory. (Jelmer Vernooij, #905594)

* A sane default is provided for ``ssl.ca_certs`` which should points to the

  Certificate Authority bundle for supported platforms.

  (Vincent Ladeuil, #920455)

* ``bzr branch`` generates correct target branch locations again if not

  specified. (Jelmer Vernooij, #919218)

* ``bzr send`` works on treeless branches again.

  (Jelmer Vernooij, #921591)

* ``bzr version`` no longer throws a UnicodeDecodeError if the .bzr.log path

  contains non-ascii characters. (Martin Packman, #312841)

* Support scripts that don't call bzrlib.initialize() but still call run_bzr().

  (Vincent Ladeuil, #917733)

* Test for equality instead of object identity where ROOT_PARENT is concerned.

  (Wouter van Heyst, #881142)

API Changes

***********

* ``config.config_dir`` and related functions now always return paths as

  unicode. (Martin Packman, #825826)

* ``ControlDir`` now has a new method ``set_branch_reference`` which can

  be used for setting branch references. (Jelmer Vernooij)

* ``ControlDir.destroy_branch`` now raises ``NotBranchError`` rather than

  ``NoSuchFile`` if the branch didn't exist. (Jelmer Vernooij, #921693)

Internals

*********

* A new matcher ``RevisionHistoryMatches`` has been added. (Jelmer Vernooij)

* Add new module ``bzrlib.url_policy_open``. (Jelmer Vernooij, #850843)

* ``MutableTree`` has two new hooks ``pre_transform`` and

  ``post_transform`` that are called for tree transform operations.

  (Jelmer Vernooij, #912084)

Testing

*******

* Be more careful about closing open files for pypy interoperability.

  (Wouter van Heyst)

bzr 2.5b5

#########

:2.5b5: 2012-01-12

This is the fifth (and last) beta of the 2.5 series, leading to a 2.5.0

release in February 2012. Beta releases are suitable for everyday use but

may cause some incompatibilities with plugins.

This release includes many improvements in the smart server, UI polish for

the colocated branches, enhancements to the config framework and more

internal uses, bug fixes related to unicode and locale support and more.

All bug fixed in previous series known at the time of this release are

included.

External Compatibility Breaks

*****************************

* The '.bzr/branch/email' file is no longer read to determine the users'

  identity. Instead, the 'email' setting in '.bzr/branch/branch.conf'

  should be used. (Jelmer Vernooij, #903894)

New Features

************

* "bzr mkdir" now includes -p (--parents) option for recursively adding

  parent directories.

  (Jared Hance, Jelmer Vernooij, #253529)

* ``config.Option`` can now declare ``override_from_env``, a list of

  environment variables which, when set, that takes precedence over values

  defined in configuration files. (Vincent Ladeuil, #907279)

Improvements

************

* New HPSS call for ``Repository.reconcile``. (Jelmer Vernooij, #894455)

* Merge now has two new hooks ``pre_merge`` and ``post_merge``

  that are called before and after a merge and can make

  additional modifications to the trees involved.

  (Jelmer Vernooij, #906877)

* Override the value returned by ``sys.getfilesystemencoding()`` for the bzr

  script to utf-8 when it would otherwise be ascii on a posix system. This

  will mean bzr works with non-ascii files when no locale or an incorrect

  locale is set. (Martin Packman, #794353)

* ``bzr branches`` now indicates the active colocated branch.

  (Jelmer Vernooij, #891667)

* ``bzr push`` now suggests using :parent if there is a parent location

  set. (Jelmer Vernooij)

* ``bzr send`` now only opens a single connection, rather than two,

  to the target branch.  (Jelmer Vernooij)

Bug Fixes

*********

* Allow configuration option default value to be a python callable at

  registration. (Vincent Ladeuil, #832064)

* ``bzr config`` will now display the section ``[DEFAULT]`` used in

  ``bazaar.conf``. (Vincent Ladeuil, #907268)

* Configuration stores can now provides a specific quoting mechanism. This

  is required to workaround ``configobj`` conflating quoting and list values

  automatic conversion. (Vincent Ladeuil, #906897)

* Create obsolete_packs directory when repacking if it does not

  exist. (Jonathan Riddell, Jelmer Vernooij, #314314)

* Fallback to the slower ``bzr log`` implementation when displaying a range

  of revisions whose ancestry is not obviously on the same developement

  line. (Vincent Ladeuil, #904744)

* Make lazy imports resilient when resolved concurrently from multiple

  threads. Now the stand-in object will behave as a proxy for the real object

  after the initial access, rather than throwing. Assigning the object to

  multiple names should still be avoided. (Martin von Gagern, #396819)

* Not setting ``gpg_signing_key`` or setting it to ``default`` will use the

  user email (obtained from the ``email`` configuration option or its

  default value). (Vincent Ladeuil, Jelmer Vernooij, #904550)

* Prevent spurious InconsistentDelta error when committing a move of a

  non-ascii directory with contents. (Rory Yorke, #185211)

* Properly ignore '\n' in an option reference since this cannot be part of a

  config option identifier. (Vincent Ladeuil, #902125)

* Make sure that the bzr probers are always registered when

  bzrlib.workingtree is imported. (Jelmer Vernooij, #905218)

* Report mistake trying to move a removed file with a non-ascii name without

  UnicodeEncodeError being raised. (Martin Packman, #898541)

* Safely unquote configuration values in weird edge cases (a section seen as

  a dictionary which is not a supported use case for the configuration

  stacks). (Vincent Ladeuil, #908050)

* Stop altering ``sys.platform`` on OSX when initialising the locale.

  (Martin Packman, #570495)

* Uncommit no longer removes tags if they are part of the working

  trees pending merges. (Jelmer Vernooij, #905462)

API Changes

***********

* ``Config.signature_needed``, ``Config.signing_policy``,

  ``Config.gpg_signing_key``, ``Config.gpg_signing_command``,

  ``Config.checking_policy`` and ``Config.post_commit`` are now deprecated.

  (Jelmer Vernooij)

* ``Repository.get_commit_builder`` now takes a ``config_stack``

  rather than a ``config`` argument. (Jelmer Vernooij)

* Scripts using bzrlib should now ensure setlocale is called on posix

  platforms if they need a non-ascii user encoding. (Martin Packman)

* Send formats now accept a new optional argument ``submit_branch``,

  which can be None or a Branch object for the submit branch location.

  (Jelmer Vernooij)

* ``VersionedFileRepository.add_revision`` no longer takes a ``config``

  argument. (Jelmer Vernooij)

Internals

*********

* Add HPSS call for ``Branch.get_checkout_format``. (Jelmer Vernooij, #894459)

* Add HPSS call for ``Repository.pack``. (Jelmer Vernooij, #894461)

* Add HPSS calls for ``Repository.iter_files_bytes``, speeding up

  several commands including ``bzr export`` and ``bzr co --lightweight``.

  (Jelmer Vernooij, #608640)

* All bzr control directories, branch formats, repository formats and

  working tree formats now support feature flags, which are

  serialized in their respective format files. See

  ``doc/developers/feature-flags.txt`` for details.

  (Jelmer Vernooij)

* ``bzrlib.urlutils`` now includes ``quote`` and ``unquote`` functions,

  rather than importing them from ``urllib``. This prevents loading

  of the ``socket``, ``ssl`` and ``urllib`` modules for

  local bzr operations. (Jelmer Vernooij)

* Configuration options can be SI units by using ``int_SI_from_unicode`` as

  their ``convert_from_unicode`` helper. (Vincent Ladeuil)

* Configuration stacks can now use ``StartingPathMatcher`` to select the

  sections matching a location while respecting the order chosen by the user

  in the configuration file: from generic sections to specific

  sections. (Vincent Ladeuil, #832046).

* Configuration stores can now save incremental changes by using

  ``save_changes()`` instead of ``save()``. This reduces the number or

  required input/outputs and allows stores to be shared between

  stacks. (Vincent Ladeuil)

* ControlDir now has a get_branches method that returns a dictionary

  whose keys are the names of the branches and whose values are the

  branches themselves. The active branch uses the key None.

  (Neil Martinsen-Burrell)

* Helper ``osutils.path_from_environ`` added for extracting a unicode path

  from an environment variable. (Martin Packman, #832028)

* Helper ``win32utils.get_environ_unicode`` added for avoiding encoding

  problems with ``os.environ.get`` use. (Martin Packman, #262874) 

* Lazy imports can now only be absolute. (Jelmer Vernooij)

* Merge3Mergers now have an optional ``other_branch`` argument

  which contains the branch from which the ``other_tree``

  was obtained, if any. (Jelmer Vernooij)

* MutableTree now has a hook ``post_build_tree`` which is called after

  a new mutable tree has been created. (Jelmer Vernooij, #912765)

* New HPSS call ``BzrDir.checkout_metadir``. (Jelmer Vernooij, #894459)

* New HPSS call ``VersionedFileRepository.get_inventories``,

  speeding up various commands including ``bzr export``,

  ``bzr checkout`` and ``bzr cat``. (Jelmer Vernooij, #608640)

* The ``ConfigCommandLineStore`` is now supported by ``bzr config`` and is

  seen as single no-name section of configuration options. (Vincent Ladeuil)

Testing

*******

* New matcher ``ContainsNoVfsCalls`` which filters a list of HPSS

  calls for VFS requests. (Jelmer Vernooij)

* New ``MemoryStack`` class allows for diskless tests and locally injected

  configuration stacks.  Lower level tests for predefined set of options can

  be written without setting up configuration files. (Vincent Ladeuil)

bzr 2.5b4

#########

:2.5b4: 2011-12-08

This is the fourth beta of the 2.5 series, leading to a 2.5.0 release in

February 2012. Beta releases are suitable for everyday use but may cause

some incompatibilities with plugins.

This release includes many improvements in the smart server, UI polish for

the colocated branches, optimizations for revision specifiers to avoid

history sized operations, enhancements to the config framework, bug fixes

related to unicode paths and more.

All bug fixed in previous series known at the time of this release are

included.

External Compatibility Breaks

*****************************

None.

New Features

************

  ``msgmerge``. See ``bzr help po_merge`` for details.

  (Vincent Ladeuil, #884270)

Improvements

************

* ``bzr branch --stacked`` now only makes a single connection to the remote

  server rather than three. (Jelmer Vernooij, #444293)

* ``bzr export --uncommitted`` will export the uncommitted tree.

  (Jelmer Vernooij, #555613)

* ``bzr rmbranch`` can now remove colocated branches.

  (Jelmer Vernooij, #831464)

  (Francis Devereux)

* ``bzr switch`` now accepts colocated branch names to switch to.

  (Jelmer Vernooij, #826814)

* Plugins can now register additional "location aliases".

  (Jelmer Vernooij)

* Revision specifiers will now only browse as much history as they

  need to, rather than grabbing the whole history unnecessarily in some

  cases. (Jelmer Vernooij)

* When using ``bzr switch`` to switch to a sibling of the current

  branch, the relative branch name should no longer be url-encoded.

  (Jelmer Vernooij)

Bug Fixes

*********

* A new section local option ``basename`` is available to help support some

  ``bzr-pipeline`` workflows and more generally help mapping local paths to

  remote ones. See ``bzr help configuration`` for more details.

  (Vincent Ladeuil, #843211)

* Add HPSS call for looking up revision numbers from revision ids on

  remote repositories. (Jelmer Vernooij, #640253)

* Add HPSS call for retrieving file contents from remote repositories.

  Should improve performance for lightweight checkouts and exports of

  from remote repositories.  (Jelmer Vernooij, #368717, #762330, #608640)

  prohibits several invalid strings, reads the correct number of seconds,

  and gives a better error message if the time zone offset is not given.

  (Matt Giuca, #892657)

* Give meaningful file/line references when reporting deprecation warnings

  for _CompatabilityThunkFeature based test features.

  (Vincent Ladeuil, #897718)

* Make reporting of mistakes involving unversioned files with non-ascii

  filenames work again without 'Unprintable exception' being shown.

  (Martin Packman, #898408)

* Provide names for lazily registered hooks. 

  (Neil Martinsen-Burrell, #894609)

* Raise BadIndexKey exception in btree_index when a key is too large, fixing 

  an infinite recursion issue. (Shannon Weyrick, #720853)

* Resolve regression from colocated branch path handling, by ensuring that

  unreserved characters are unquoted in URLs. (Martin Packman, #842223)

* Support verifying signatures on remote repositories.

  (Jelmer Vernooij, #889694)

* Teach the bzr client how to reconnect if we get ``ConnectionReset``

  while making an RPC request. This doesn't handle all possible network

  disconnects, but it should at least handle when the server is asked to

  shutdown gracefully. (John Arbash Meinel, #819604)

* When a remote format is unknown, bzr will now print a single-line error

  message rather than a backtrace. (Jelmer Vernooij, #687226)

API Changes

***********

  is deprecated. The ``revs`` argument of

  ``RevisionInfo.from_revision_id`` is now deprecated. (Jelmer Vernooij)

* ``Tree.get_file_by_path`` is now deprecated. Use ``Tree.get_file`` instead.

  (Jelmer Vernooij, #666897)

* Some global options for use with commands have been removed, construct

  an ``Option`` with the name instead. (Martin Packman)

* The unused exception ``HistoryMissing`` has been removed.

  (Jelmer Vernooij)

Internals

*********

* Add HPSS call for ``Repository.pack``. (Jelmer Vernooij, #894461)

* ``bzr config`` uses the new configuration implementation.

  (Vincent Ladeuil)

* Custom HPSS error handlers can now be installed in the smart server client

  using the ``error_translators`` and ``no_context_error_translators``

  registries. (Jelmer Vernooij)

* New HPSS calls ``Repository.has_signature_for_revision_id``,

  ``Repository.make_working_trees``, ``BzrDir.destroy_repository``,

  ``BzrDir.has_workingtree``, ``Repository.get_physical_lock_status``,

  ``Branch.get_physical_lock_status``,

  ``merge.get_merge_type_registry`` remains as an accessor. (Martin Packman)

Testing

*******

* Avoid failures in test_transform when OS error messages are localised.

  (Martin Packman, #891582)

* Tests are now subject to a time limit: by default 300s, and 120s when

  run from 'make check', controlled by the `selftest.timeout`

  configuration option.  This is currently not supported on Windows.

bzr 2.5b3

#########

:2.5b3: 2011-11-10

This is the third beta of the 2.5 series, leading to a 2.5.0 release in

February 2012. Beta releases are suitable for everyday use but may cause

some incompatibilities with plugins.

This release includes log options for ``push`` and ``pull``, more UI polish

for colocated branches, a better and more coherent implementation for UI

dialogs, enhancements to the config framework and more.

This release includes all bug fixed in previous series known at the time of

this release.

External Compatibility Breaks

*****************************

None

New Features

************

* The ``log_format`` configuration can be used with ``-Olog_format=line`` to

  change the format ``push`` and ``pull`` use to display the

  revisions. I.e.: ``bzr pull -v -Olog_format=short`` will use the ``short``

  format instead of the default ``long`` one. (Vincent Ladeuil, #861472)

* The new config scheme allows an alternative syntax for the 'appenpath'

  policy relying on option expansion and defining a new 'relpath' option

  local to a section. Instead of using '<option>:policy=appendpath', the

  option value can de defined as 'option=xxxx/{relpath}'.

  (Vincent Ladeuil, #832013)

Improvements

************

* ``bzr info -v`` now shows the number of colocated branches

  for control directories that support them.

  (Jelmer Vernooij, #863285)

* ``bzr version-info`` now takes a ``--revision`` argument.

  (Jelmer Vernooij, #238705)

* ``bzr revno`` now takes a ``--revision`` argument.

  (Jelmer Vernooij, #870649)

* ``bzr serve`` now can serve from URLs rather than just from the

  file system. I.e.: ``bzr serve -d lp:bzr`` or

  ``bzr serve -d file:///data/bzr`` (Jelmer Vernooij)

* all input prompts are now char-based when possible, and can be forced to

  line-based mode by setting the ``BZR_TEXTUI_INPUT`` environment variable

  to 'line-based'. This replace the previous shelf UI only patch using

  ``INSIDE_EMACS``. (Benoît Pierre)

Bug Fixes

*********

* ``bzr info`` now shows the master branch location too for

  treeless local branches. (Jelmer Vernooij, #258355)

* ``bzr mkdir --quiet`` now does not print a line for every created

  directory. (Martin von Gagern, #869915)

* ``bzr mv`` does not crash when attempting to move the root of a

  branch. (Jonathan Riddell, #809728)

* ``bzr shelve`` now use ``UIFactory.choose`` for input handling, making

  it usable when creating a custom ``UIFactory`` implementation. (Benoît

  Pierre)

* ``bzr clean-tree`` now use ``UIFactory.get_boolean`` for confirmation

  prompt, making it usable when using a custom ``UIFactory``

  implementation. (Benoît Pierre)

* If sending a crash through Apport fails report the Apport failure to

  bzr.log rather than stderr. (Jonathan Riddell, #766735)

* ``bzr upgrade`` no longer treats 'already up-to-date' exceptions as

  errors. (Benoît Pierre, #716560).

* ``bzr version-info`` no longer populates the clean state for custom

  templates unless {clean} is explicitly asked for.

  (Lawrence Mitchell, #882541)

* Fix finding the CPU count when using Python >= 2.6 on BSD-based systems.

  (Jelmer Vernooij, #887151)

* ``WorkingTree.clone()`` now supports its ``revision_id`` being set

  to the null revision. (Jelmer Vernooij, #876423)

* ``WorkingTree.pull`` can now pull ``NULL_REVISION``.

  (Jelmer Vernooij, #887556)

API Changes

***********

* ``Branch.revision_history`` is now deprecated. (Jelmer Vernooij, #799519)

* Methods ``add`` and ``items`` of ``LRUCache`` and ``LRUSizeCache`` are

  deprecated. Use normal dict-style access instead. (Martin Packman)

* New flag ``RepositoryFormat.supports_unreferenced_revisions`` which

  indicates whether revisions can be present in a repository without

  being referenced from e.g. a branch history at the same time.

  (Jelmer Vernooij)

* ``UIFactory.choose`` has been added: prompt the user for a list of

  choices. (Benoît Pierre)

Internals

*********

* ``ControlDirFormat`` now has a new method ``supports_transport``

  which format implementations can use whether or not they can access

  a control dir over a particular transport. (Jelmer Vernooij)

* ``BranchBuilder.build_commit`` now take ``parent_ids`` and

  ``allow_leftmost_as_ghost`` arguments.  (Jelmer Vernooij)

Testing

*******

* Ensure TestCase instances are deallocated immediately after running where

  possible. This greatly reduces the peak resource needs of a full test suite

  run. The new ``-Euncollected_cases`` selftest flag will add failures if any

  case which persists pasts its expected lifetime. (Martin Packman, #613247)

* Report exceptions from child processes during fork instead of swallowing the

  error and reporting that everything went okay. (Martin Packman, #804130)

bzr 2.5b2

#########

This is the second beta of the 2.5 series, leading to a 2.5.0 release in

February 2012. Beta releases are suitable for everyday use but may cause some

incompatibilities with plugins.

This release includes more filtering options for ``bzr log``, idle

connections handling for ``bzr serve``, a ``development-colo`` experimental

format to flesh out the colocated branches UI, better support for foreign

formats, enhancements to the config framework and more.

This release includes all bug fixed in previous series known at the time of

this release.

:2.5b2: 2011-10-06

External Compatibility Breaks

*****************************

None

New Features

************

* A new ``-O`` standard option (common to all commands) have been added. It

  provides a value for a config option in the ``-Oname=value`` form that

  takes precedence over all definitions found in config files.  It can be

  used multiple times to override different options.

  (Vincent Ladeuil, #491196)

* ``bzr log`` now has an option called ``--omit-merges`` to omit

  those commits that merged branches, i.e. those having more than one

  parent.

  In order to avoid confusion, the previous command line option

  ``--include-merges`` has been renamed to ``--include-merged``.

  The old name of the command line option will still be accepted.

  The name change also affects ``bzr missing``.

  (Martin von Gagern)

* ``bzr serve`` will now disconnect clients if they have not issued an RPC

  request after 5minutes. On POSIX platforms, this will also happen for

  ``bzr serve --inet``. This can be overridden with the configuration

  variable ``serve.client_timeout`` or in the command line parameter

  ``bzr serve --client-timeout=X``. Further, it is possible to request

  ``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will

  finish the current request, and then close the connection.

  (John Arbash Meinel, #824797, #795025)

* The new experimental format ``development-colo`` supports colocated

  branches. This format will eventually be merged back into the ``2a``

  format when it has stabilized and there is adequate UI support for

  colocated branches.

  (Jelmer Vernooij, #831481)

Improvements

************

* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for

  every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)

* ``bzr info -v`` can now be run against branches that don't support

  ``last_revision_info``, in which case the branch information will simply

  not be displayed. (Jelmer Vernooij)

Bug Fixes

*********

* ``bzr shelve`` can now be used in emacs shells as the input handling is

  turned into a line-based one when ``INSIDE_EMACS`` is set (which is the

  case for all recent emacs versions). (Vincent Ladeuil, #856261)

* ``bzr tags`` can now be used against remote repositories that do

  not provide access to the revision graph. (Jelmer Vernooij, #858942)

* ``bzr update PATH`` will stop if you seem to be asking it to update

  anything less than a whole tree, because that's not supported by ``bzr``'s

  concept that the whole tree has a single basis revision.  Previously, it

  would go ahead and update the whole tree, which was surprising.

  (Martin Pool, #557886)

* Don't crash if ``bzrlib.initialize()`` has not been called while accessing

  configs.  (Vincent Ladeuil, #863401)

* Redirects between http and https no longer discard path information

  in some cases. (Jelmer Vernooij, #853765)

* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer

  reports all tags as changed. (Jelmer Vernooij, #845396)

* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is

  specified that is unknown. (Jelmer Vernooij, #847435)

API Changes

***********

* ``Branch.get_revision_delta`` has been deprecated. Use

  ``Repository.get_revision_delta`` instead. (Jelmer Vernooij, #859712)

* Plugins that implement custom protocols for ``bzr serve`` should now

  also take an argument ``timeout``. This is used by the the bzr protocol

  to close a connection if a client has been idle for more than X seconds.

  (Default 5minutes). (John Arbash Meinel)

* ``Repository.fileids_altered_by_revision_ids`` has been moved to

  ``VersionedFileRepository`` and is no longer part of the standard

  ``Repository`` interface. (Jelmer Vernooij)

* The argument ``include_merges`` to ``missing.find_unmerged`` has

  been renamed to ``include_merged``. The old name is still supported

  for now but will cause a deprecation warning. (Martin von Gagern)

* The new method ``ControlDirFormat.is_initializable()`` returns a boolean

  indicating whether or not it is possible to use any of the

  initialization methods of that format to create a new control dir.

  (Jelmer Vernooij)

Internals

*********

* ``Branch`` objects can now use a config stack with the newly introduced

  ``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can

  be used for the same branch but it's recommended to stick to one for a

  given option.

Testing

*******

* Test scripts can now use ``bzr shelve`` and provide their input as

  complete lines. (Vincent Ladeuil, #856261)

* Really corrupt the pack file without depending on a special length or value.

  (Vincent Ladeuil, #807032)

bzr 2.5b1

#########

:2.5b1: 2011-09-15

This is the first beta of the 2.5 series, leading up to a 2.5.0

release in February 2012.

This release includes better support for gpg signing, better support for

i18n (mostly command help and error messages), more options to filter ``bzr

log`` output, more support for colocated branches ("location,branch=XXX"

syntax), better feedback on updated tags for various commands, faster

branching into an empty repository, enhancements to the config framework and

more.

Beta releases are suitable for everyday use but may cause some

incompatibilities with plugins.  Some plugins may need small updates to work

with 2.5b1.

External Compatibility Breaks

New Features

************

* A ``from_unicode`` parameter can be specified when registering a config

  option. This implements boolean, integer and list config options when the

  provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``

  are used for this parameter.  (Vincent Ladeuil)

* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now

  checks to see if the most recent published source package version for

  that project is present in the branch tags. This should help developers

  trust whether the packaging branch is up-to-date and can be used for new

  changes. The level of verbosity is controlled by the config item

  ``launchpad.packaging_verbosity``. It can be set to one of

  off

    disable all checks

  minimal

    only display if the branch is out-of-date

  short

    also display single-line up-to-date and missing,
