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.

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)
* urllib-based HTTPS client connections now verify the server certificate
validity as well as the hostname.
(Jelmer Vernooij, Vincent Ladeuil, #651161)
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)

* 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)

``msgmerge``. See ``bzr help po_merge`` for details.
(Vincent Ladeuil, #884270)
Improvements
************

(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)
* Allow lazy compiled patterns from ``bzrlib.lazy_regex`` to be
pickled. (Jelmer Vernooij, #893149)
* ``bzr info`` no longer shows empty output if only a control
directory is present. (Jelmer Vernooij, #159098)

* Fix test failures on windows related to locations.conf handling.
(Vincent Ladeuil, #892992)
* Fixed parsing of the timestamp given to ``commit --commit-time``. Now
prohibits several invalid strings, reads the correct number of seconds,

(Matt Giuca, #892657)
* Give meaningful file/line references when reporting deprecation warnings
for _CompatabilityThunkFeature based test features.
(Vincent Ladeuil, #897718)

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)

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
***********

(Jelmer Vernooij, #666897)
* Some global options for use with commands have been removed, construct
an ``Option`` with the name instead. (Martin Packman)

(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``,

*******
* 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
*****************************
None
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,
all
(default) display multi-line content for all states
(John Arbash Meinel, #609187, #812928)
* Add a config option gpg_signing_key for setting which GPG key should
be used to sign commits. Also default to using the gpg user identity
which matches user_email() as set by whoami.
(Jonathan Riddell, #68501)
* An ``invalid`` parameter can be specified when registering a config option
to decide what should be done when invalid values are
encountered. 'warning' and 'error' will respectively emit a warning and
ignore the value or errors out. (Vincent Ladeuil)
* bzr add now skips large files in recursive mode. The default "large"
size is 20MB, and is configurable via the add.maximum_file_size
option. A value of 0 disables skipping. Named items passed to add are
never skipped. (Shannon Weyrick, #54624)
* ``bzr help configuration/<option>`` display the help for ``option`` for
all registered configuration options. (Vincent Ladeuil, #747050)
* ``bzr log -m`` now matches message, author, committer and bugs instead
of just matching the message. ``--message`` keeps its original meaning,
while ``--match-message, --match-author, --match-committer`` and
``--match-bugs`` match each of those fields. (Jacek Sieka)
* ``config.Option`` can now declare ``default_from_env``, a list of
environment variables to get a default value from. (Vincent Ladeuil)
* ``config.NameMatcher`` can be used to implement config stores and stacks
that need to provide specific option values for arbitrary unique IDs (svn
repository UUIDs, etc). (Vincent Ladeuil, #843638)
* New builtin ``bzr branches`` command, which lists all colocated branches
in a directory. (Jelmer Vernooij, #826820)
* Relative local paths can now be specified in URL syntax by using the
"file:" prefix. (Jelmer Vernooij)
* Report commits signed with expired keys in ``verify-signatures``.
(Jonathan Riddell, #804254)
* Translations are now enabled for command help, errors and globally
for any message using ``gettext`` given on output. (Jonathan Riddell,
INADA Naoki, #83941)
Improvements
************
* ``bzr add`` will now warn about nested subtrees that are skipped.
(Jelmer Vernooij, #187342)
* ``bzr commit -m ''`` can now be used to force an empty commit message.
Entering an empty commit message in the message editor still triggers
an error. (Jelmer Vernooij)
* ``bzr pull`` will now mention how many tags it has updated.
(Jelmer Vernooij, #164450)
* ``bzr tag`` no longer errors if a tag already exists but refers to the
same revision, and will mention when a tag has been updated
rather than created. (Jelmer Vernooij, #381203)
* ``bzr uncommit`` will now remove tags that refer to removed revisions.
The ``--keep-tags`` option can be used to prevent this behaviour.
(Jelmer Vernooij, #605814)
* Do not run i18n initialisation twice. (Jonathan Riddell)
* Install translation .mo files. (Jonathan Riddell)
* Locations printed by ``bzr upgrade`` are now formatted before display.
(Jelmer Vernooij)
* ``Repository.get_parent_map`` now estimates the size of the returned
content more accurately. This means that we get closer to the desired
64kB/request. For repositories converted from svn, this can be an
improvement of approx 5:1 in round trips to discover the whole history.
(John Arbash Meinel)
* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
if no bug tracker was specified on the command line.
(Jelmer Vernooij, #334860)
* Use ``gettext.NullTranslations`` in i18n to allow use of i18n even when
translations are not turned on. (Jonathan Riddell)
Bug Fixes
*********
* ``bzr commit`` now correctly reports missing files as "removed", not
"modified". (Jelmer Vernooij, #553955)
* ``bzr reconfigure`` will now allow multiple non-conflicting requests
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
(Martin von Gagern, #842993)
* A call to CHKInventory's filter-method will not result in a
DuplicateFileId error, if you move a subfolder and change a file in
that subfolder.
(Bastian Bowe, #809901)
* Branching from a stacked branch no longer does a ``get_parent_map``
request for each revisions that is in the stacked-on repository while
determining what revisions need to be fetched. This mostly impacts
branching initialy into an empty shared repository when the source is
not the development focus. (John Arbash Meinel, #388269)
* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
errors. (Vincent Ladeuil, #822571)
* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
raised whenever a transport at the drive root was opened on windows.
(Martin [gz], #841322)
* Fixed loading of external merge tools from config to properly decode
command-lines which contain embedded quotes. (Gordon Tyler, #828803)
* Rather than an error being raised, a warning is now printed when the
current user does not have permission to read a configuration file.
(Jelmer Vernooij, #837324)
* The pull command will now always use separate connections for the
case where the destination is a heavyweight checkout of some remote
branch on the same host as the source branch.
(Martin von Gagern, #483661)
* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
operations that use it, like merge, can now create trees without a root.
(Aaron Bentley)
Documentation
*************
* Release instructions refreshed. (Vincent Ladeuil)
API Changes
***********
* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
argument. (Jelmer Vernooij)
* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
which indicates if the format should be for a lightweight or a
heavyweight checkout. (Jelmer Vernooij)
* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
(Jelmer Vernooij)
* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
(Jelmer Vernooij)
* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
(Shannon Weyrick)
* New method ``InterTree.file_content_matches`` which checks that
two files in different trees have the same contents.
(Jelmer Vernooij)
* New method ``Tree.get_file_verifier`` which allows tree implementations
to return non-sha1 checksums to verify files.
(Jelmer Vernooij, #720831)
* New methods ``get_transport_from_path`` and ``get_transport_from_url``
have been added that only support opening from a path or a URL,
unlike ``get_transport``. (Jelmer Vernooij)
* New registry ``OptionRegistry`` specialized for configuration options.
(Vincent Ladeuil)
* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
(Vincent Ladeuil)
* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
2.10 and 2.2.0. (Vincent Ladeuil)
* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.
* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
remove ``log.show_one_log`` which was never properly deprecated but wasn't
used and is easy to inline if needed. (Vincent Ladeuil)
* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
deprecated in 2.1.0. (Vincent Ladeuil)
* Remove ``TransportListRegistry.set_default_transport``, as the concept of
a default transport is currently unused. (Jelmer Vernooij)
* Remove ``UIFactory.warn_cross_format_fetch`` and
``UIFactory.warn_experimental_format_fetch`` in favor of
``UIFactory.show_user_warning``. (Jelmer Vernooij)
* ``Tags`` containers can now declare whether they support versioned
tags and whether tags can refer to ghost tags.
(Jelmer Vernooij)
* ``Tags.merge_to`` now returns a dictionary with the updated tags
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)
* There is a new class `ContentFilterTree` that provides a facade for
content filtering. The `filtered` parameter to `export` is deprecated
in favor of passing a filtered tree, and the specific exporter plugins
no longer support it.
(Martin Pool)
* ``Transport`` now has a ``_parsed_url`` attribute instead of
separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
and ``_path`` attributes. Proxies are provided for the moment but
may be removed in the future. (Jelmer Vernooij)
Internals
*********
* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
is attempted. (Jelmer Vernooij)
* New method ``ControlDir._get_selected_branch`` which returns the
colocated branch selected using path segment parameters.
(Jelmer Vernooij, #380871)
Testing
*******
* Blackbox tests (including test scripts) can be debugged interactively (see
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
cleanly and reliably allows tests using `BranchBuilder` to construct
branches that e.g. rename files out of a directory and unversion that
directory in the same revision. Previously some changes were impossible
due to the order that `build_snapshot` performs its actions.
(Andrew Bennetts)
* Don't require ``os.fdatasync`` to be defined on all supported OSes
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)
* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
* ``LockDir`` can now be run when the local hostname is ``localhost``.
(Jelmer Vernooij, #825994)
* ``ModuleAvailableFeature`` won't try to import already imported modules,
allowing it to be used for modules with side-effects.
(Vincent Ladeuil, #712474)
* Output time stamps while running ``make check`` to get better timings from
pqm. (Vincent Ladeuil, #837926)
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
just compares the bytes in the dirstate file to its pristine state,
rather than opening the WorkingTree and calling ``last_revision()``.
This reduces the overall test suite time by about 10% on my laptop.
(Andrew Bennetts)
* Update `TestCase.knownFailure` to the testtools way of handling expected
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
