.. These may require users to change the way they use Bazaar.
22
.. New commands, options, etc that users may wish to try out.
27
.. Improvements to existing commands, especially improved performance
28
or memory usage, or better results.
33
.. Fixes for situations where bzr would previously crash or give incorrect
34
or undesirable results.
39
.. Improved or updated documentation.
44
.. Changes that may require updates in plugins or other code that uses
50
.. Major internal changes, unlikely to be visible to users or plugin
51
developers, but interesting for bzr developers.
56
.. Fixes and changes that are only relevant to bzr's test framework and
57
suite. This can include new facilities for writing tests, fixes to
58
spurious test failures and changes to the way things should be tested.
66
This is the sixth (and last (really)) beta of the 2.5 series, leading to a
67
2.5.0 release in March 2012. Beta releases are suitable for everyday use
68
but may cause some incompatibilities with plugins.
70
This introduces the support for colocated branches into the '2a' format in a
71
backward compatible way, fix more glitches in the colocated UI, verify https
72
certificates for the urllib https client implementation, fix some more
73
unicode issues and more.

*****************************
86
* Support for colocated branches is now available in the default
87
format ("2a"). (Jelmer Vernooij)
92
* ``bzr switch -b`` in a standalone tree will now create a colocated branch.
93
(Jelmer Vernooij, #918197)
95
* ``bzr info`` now reports when there are present (but unused) colocated
96
branches. (Jelmer Vernooij, #891646)
98
* Checkouts can now be into target directories that already have
99
a control directory (but no branch or working tree).
100
(Jelmer Vernooij, #913980)
102
* Checkouts of colocated branches are now always lightweight.
103
(Jelmer Vernooij, #918828)
105
* Colocated branches can now have names including forward slashes, to
106
allow for namespaces. (Jelmer Vernooij, #907980)
108
* New HPSS call for ``BzrDir.get_branches``. (Jelmer Vernooij, #894460)
110
* Two new command hooks, ``pre_command`` and ``post_command``,
111
provide notification before and after a command has been run.
112
(Brian de Alwis, Jelmer Vernooij)
117
* ``bzr branch`` now fetches revisions when branching into an empty
118
control directory. (Jelmer Vernooij, #905594)
120
* A sane default is provided for ``ssl.ca_certs`` which should points to the
121
Certificate Authority bundle for supported platforms.
122
(Vincent Ladeuil, #920455)
124
* ``bzr branch`` generates correct target branch locations again if not
125
specified. (Jelmer Vernooij, #919218)
127
* ``bzr send`` works on treeless branches again.
128
(Jelmer Vernooij, #921591)
130
* ``bzr version`` no longer throws a UnicodeDecodeError if the .bzr.log path
131
contains non-ascii characters. (Martin Packman, #312841)
133
* Support scripts that don't call bzrlib.initialize() but still call run_bzr().
134
(Vincent Ladeuil, #917733)
136
* Test for equality instead of object identity where ROOT_PARENT is concerned.
137
(Wouter van Heyst, #881142)
139
* urllib-based HTTPS client connections now verify the server certificate
140
validity as well as the hostname.
141
(Jelmer Vernooij, Vincent Ladeuil, #651161)
147
* ``config.config_dir`` and related functions now always return paths as
148
unicode. (Martin Packman, #825826)
150
* ``ControlDir`` now has a new method ``set_branch_reference`` which can
151
be used for setting branch references. (Jelmer Vernooij)
153
* ``ControlDir.destroy_branch`` now raises ``NotBranchError`` rather than
154
``NoSuchFile`` if the branch didn't exist. (Jelmer Vernooij, #921693)
159
* A new matcher ``RevisionHistoryMatches`` has been added. (Jelmer Vernooij)
161
* Add new module ``bzrlib.url_policy_open``. (Jelmer Vernooij, #850843)
163
* ``MutableTree`` has two new hooks ``pre_transform`` and
164
``post_transform`` that are called for tree transform operations.
165
(Jelmer Vernooij, #912084)
171
* Be more careful about closing open files for pypy interoperability.
179
This is the fifth (and last) beta of the 2.5 series, leading to a 2.5.0
180
release in February 2012. Beta releases are suitable for everyday use but
181
may cause some incompatibilities with plugins.
183
This release includes many improvements in the smart server, UI polish for
184
the colocated branches, enhancements to the config framework and more
185
internal uses, bug fixes related to unicode and locale support and more.

External Compatibility Breaks
191
*****************************
193
* The '.bzr/branch/email' file is no longer read to determine the users'
194
identity. Instead, the 'email' setting in '.bzr/branch/branch.conf'
195
should be used. (Jelmer Vernooij, #903894)
200
* "bzr mkdir" now includes -p (--parents) option for recursively adding
202
(Jared Hance, Jelmer Vernooij, #253529)
204
* ``config.Option`` can now declare ``override_from_env``, a list of
205
environment variables which, when set, that takes precedence over values
206
defined in configuration files. (Vincent Ladeuil, #907279)
211
* New HPSS call for ``Repository.reconcile``. (Jelmer Vernooij, #894455)
213
* Merge now has two new hooks ``pre_merge`` and ``post_merge``
214
that are called before and after a merge and can make
215
additional modifications to the trees involved.
216
(Jelmer Vernooij, #906877)
218
* Override the value returned by ``sys.getfilesystemencoding()`` for the bzr
219
script to utf-8 when it would otherwise be ascii on a posix system. This
220
will mean bzr works with non-ascii files when no locale or an incorrect
221
locale is set. (Martin Packman, #794353)
223
* ``bzr branches`` now indicates the active colocated branch.
224
(Jelmer Vernooij, #891667)
226
* ``bzr push`` now suggests using :parent if there is a parent location
227
set. (Jelmer Vernooij)
229
* ``bzr send`` now only opens a single connection, rather than two,
230
to the target branch. (Jelmer Vernooij)
235
* Allow configuration option default value to be a python callable at
236
registration. (Vincent Ladeuil, #832064)
238
* ``bzr config`` will now display the section ``[DEFAULT]`` used in
239
``bazaar.conf``. (Vincent Ladeuil, #907268)
241
* Configuration stores can now provides a specific quoting mechanism. This
242
is required to workaround ``configobj`` conflating quoting and list values
243
automatic conversion. (Vincent Ladeuil, #906897)
245
* Create obsolete_packs directory when repacking if it does not
246
exist. (Jonathan Riddell, Jelmer Vernooij, #314314)
248
* Fallback to the slower ``bzr log`` implementation when displaying a range
249
of revisions whose ancestry is not obviously on the same developement
250
line. (Vincent Ladeuil, #904744)
252
* Make lazy imports resilient when resolved concurrently from multiple
253
threads. Now the stand-in object will behave as a proxy for the real object
254
after the initial access, rather than throwing. Assigning the object to
255
multiple names should still be avoided. (Martin von Gagern, #396819)
257
* Not setting ``gpg_signing_key`` or setting it to ``default`` will use the
258
user email (obtained from the ``email`` configuration option or its
259
default value). (Vincent Ladeuil, Jelmer Vernooij, #904550)
261
* Prevent spurious InconsistentDelta error when committing a move of a
262
non-ascii directory with contents. (Rory Yorke, #185211)
264
* Properly ignore '\n' in an option reference since this cannot be part of a
265
config option identifier. (Vincent Ladeuil, #902125)
267
* Make sure that the bzr probers are always registered when
268
bzrlib.workingtree is imported. (Jelmer Vernooij, #905218)
270
* Report mistake trying to move a removed file with a non-ascii name without
271
UnicodeEncodeError being raised. (Martin Packman, #898541)
273
* Safely unquote configuration values in weird edge cases (a section seen as
274
a dictionary which is not a supported use case for the configuration
275
stacks). (Vincent Ladeuil, #908050)
277
* Stop altering ``sys.platform`` on OSX when initialising the locale.
278
(Martin Packman, #570495)
280
* Uncommit no longer removes tags if they are part of the working
281
trees pending merges. (Jelmer Vernooij, #905462)
286
* ``Config.signature_needed``, ``Config.signing_policy``,
287
``Config.gpg_signing_key``, ``Config.gpg_signing_command``,
288
``Config.checking_policy`` and ``Config.post_commit`` are now deprecated.
291
* ``Repository.get_commit_builder`` now takes a ``config_stack``
292
rather than a ``config`` argument. (Jelmer Vernooij)
294
* Scripts using bzrlib should now ensure setlocale is called on posix
295
platforms if they need a non-ascii user encoding. (Martin Packman)
297
* Send formats now accept a new optional argument ``submit_branch``,
298
which can be None or a Branch object for the submit branch location.
301
* ``VersionedFileRepository.add_revision`` no longer takes a ``config``
302
argument. (Jelmer Vernooij)
307
* Add HPSS call for ``Branch.get_checkout_format``. (Jelmer Vernooij, #894459)
309
* Add HPSS call for ``Repository.pack``. (Jelmer Vernooij, #894461)
311
* Add HPSS calls for ``Repository.iter_files_bytes``, speeding up
312
several commands including ``bzr export`` and ``bzr co --lightweight``.
313
(Jelmer Vernooij, #608640)
315
* All bzr control directories, branch formats, repository formats and
316
working tree formats now support feature flags, which are
317
serialized in their respective format files. See
318
``doc/developers/feature-flags.txt`` for details.
321
* ``bzrlib.urlutils`` now includes ``quote`` and ``unquote`` functions,
322
rather than importing them from ``urllib``. This prevents loading
323
of the ``socket``, ``ssl`` and ``urllib`` modules for
324
local bzr operations. (Jelmer Vernooij)
326
* Configuration options can be SI units by using ``int_SI_from_unicode`` as
327
their ``convert_from_unicode`` helper. (Vincent Ladeuil)
329
* Configuration stacks can now use ``StartingPathMatcher`` to select the
330
sections matching a location while respecting the order chosen by the user
331
in the configuration file: from generic sections to specific
332
sections. (Vincent Ladeuil, #832046).
334
* Configuration stores can now save incremental changes by using
335
``save_changes()`` instead of ``save()``. This reduces the number or
336
required input/outputs and allows stores to be shared between
337
stacks. (Vincent Ladeuil)
339
* ControlDir now has a get_branches method that returns a dictionary
340
whose keys are the names of the branches and whose values are the
341
branches themselves. The active branch uses the key None.
342
(Neil Martinsen-Burrell)
344
* Helper ``osutils.path_from_environ`` added for extracting a unicode path
345
from an environment variable. (Martin Packman, #832028)
347
* Helper ``win32utils.get_environ_unicode`` added for avoiding encoding
348
problems with ``os.environ.get`` use. (Martin Packman, #262874)
350
* Lazy imports can now only be absolute. (Jelmer Vernooij)
352
* Merge3Mergers now have an optional ``other_branch`` argument
353
which contains the branch from which the ``other_tree``
354
was obtained, if any. (Jelmer Vernooij)
356
* MutableTree now has a hook ``post_build_tree`` which is called after
357
a new mutable tree has been created. (Jelmer Vernooij, #912765)
359
* New HPSS call ``BzrDir.checkout_metadir``. (Jelmer Vernooij, #894459)
361
* New HPSS call ``VersionedFileRepository.get_inventories``,
362
speeding up various commands including ``bzr export``,
363
``bzr checkout`` and ``bzr cat``. (Jelmer Vernooij, #608640)
365
* The ``ConfigCommandLineStore`` is now supported by ``bzr config`` and is
366
seen as single no-name section of configuration options. (Vincent Ladeuil)
371
* New matcher ``ContainsNoVfsCalls`` which filters a list of HPSS
372
calls for VFS requests. (Jelmer Vernooij)
374
* New ``MemoryStack`` class allows for diskless tests and locally injected
375
configuration stacks. Lower level tests for predefined set of options can
376
be written without setting up configuration files. (Vincent Ladeuil)
384
This is the fourth beta of the 2.5 series, leading to a 2.5.0 release in
385
February 2012. Beta releases are suitable for everyday use but may cause
386
some incompatibilities with plugins.
388
This release includes many improvements in the smart server, UI polish for
389
the colocated branches, optimizations for revision specifiers to avoid
390
history sized operations, enhancements to the config framework, bug fixes
391
related to unicode paths and more.

*****************************
404
* Provides a ``po_merge`` plugin to automatically merge ``.po`` files with
405
``msgmerge``. See ``bzr help po_merge`` for details.
406
(Vincent Ladeuil, #884270)
411
* ``bzr branch --stacked`` now only makes a single connection to the remote
412
server rather than three. (Jelmer Vernooij, #444293)
414
* ``bzr export --uncommitted`` will export the uncommitted tree.
415
(Jelmer Vernooij, #555613)
417
* ``bzr rmbranch`` can now remove colocated branches.
418
(Jelmer Vernooij, #831464)
420
* ``bzr status`` no longer shows shelves if files are specified.
423
* ``bzr switch`` now accepts colocated branch names to switch to.
424
(Jelmer Vernooij, #826814)
426
* Plugins can now register additional "location aliases".
429
* Revision specifiers will now only browse as much history as they
430
need to, rather than grabbing the whole history unnecessarily in some
431
cases. (Jelmer Vernooij)
433
* When using ``bzr switch`` to switch to a sibling of the current
434
branch, the relative branch name should no longer be url-encoded.
440
* A new section local option ``basename`` is available to help support some
441
``bzr-pipeline`` workflows and more generally help mapping local paths to
442
remote ones. See ``bzr help configuration`` for more details.
443
(Vincent Ladeuil, #843211)
445
* Add HPSS call for looking up revision numbers from revision ids on
446
remote repositories. (Jelmer Vernooij, #640253)
448
* Add HPSS call for retrieving file contents from remote repositories.
449
Should improve performance for lightweight checkouts and exports of
450
from remote repositories. (Jelmer Vernooij, #368717, #762330, #608640)
452
* Allow lazy compiled patterns from ``bzrlib.lazy_regex`` to be
453
pickled. (Jelmer Vernooij, #893149)
455
* ``bzr info`` no longer shows empty output if only a control
456
directory is present. (Jelmer Vernooij, #159098)
458
* Cope with missing revision ids being specified to
459
``Repository.gather_stats`` HPSS call. (Jelmer Vernooij, #411290)
461
* Fix test failures on windows related to locations.conf handling.
462
(Vincent Ladeuil, #892992)
464
* Fixed parsing of the timestamp given to ``commit --commit-time``. Now
465
prohibits several invalid strings, reads the correct number of seconds,
466
and gives a better error message if the time zone offset is not given.
467
(Matt Giuca, #892657)
469
* Give meaningful file/line references when reporting deprecation warnings
470
for _CompatabilityThunkFeature based test features.
471
(Vincent Ladeuil, #897718)
473
* Make reporting of mistakes involving unversioned files with non-ascii
474
filenames work again without 'Unprintable exception' being shown.
475
(Martin Packman, #898408)
477
* Provide names for lazily registered hooks.
478
(Neil Martinsen-Burrell, #894609)
480
* Raise BadIndexKey exception in btree_index when a key is too large, fixing
481
an infinite recursion issue. (Shannon Weyrick, #720853)
483
* Resolve regression from colocated branch path handling, by ensuring that
484
unreserved characters are unquoted in URLs. (Martin Packman, #842223)
486
* Split segments from URLs for colocated branches without assuming the
487
combined form is valid. (Martin Packman, #842233)
489
* Support looking up revision numbers by revision id in empty branches.
490
(Jelmer Vernooij, #535031)
492
* Support verifying signatures on remote repositories.
493
(Jelmer Vernooij, #889694)
495
* Teach the bzr client how to reconnect if we get ``ConnectionReset``
496
while making an RPC request. This doesn't handle all possible network
497
disconnects, but it should at least handle when the server is asked to
498
shutdown gracefully. (John Arbash Meinel, #819604)
500
* When a remote format is unknown, bzr will now print a single-line error
501
message rather than a backtrace. (Jelmer Vernooij, #687226)
506
* ``BzrDir.open_branch`` and ``BranchFormat.open`` now take an optional
507
``possible_transports`` argument. (Jelmer Vernooij)
509

511
* ``Repository.verify_revision`` has been renamed to
512
``Repository.verify_revision_signature``. (Jelmer Vernooij)
514
* ``RevisionSpec.wants_revision_history`` now defaults to ``False`` and
515
is deprecated. The ``revs`` argument of
516
``RevisionInfo.from_revision_id`` is now deprecated. (Jelmer Vernooij)
518
* ``Tree.get_file_by_path`` is now deprecated. Use ``Tree.get_file`` instead.
519
(Jelmer Vernooij, #666897)
521
* Some global options for use with commands have been removed, construct
522
an ``Option`` with the name instead. (Martin Packman)
524
* The unused exception ``HistoryMissing`` has been removed.
530
* Add HPSS call for ``Repository.pack``. (Jelmer Vernooij, #894461)
532
* ``bzr config`` uses the new configuration implementation.
535
* Custom HPSS error handlers can now be installed in the smart server client
536
using the ``error_translators`` and ``no_context_error_translators``
537
registries. (Jelmer Vernooij)
539
* New HPSS calls ``Repository.has_signature_for_revision_id``,
540
``Repository.make_working_trees``, ``BzrDir.destroy_repository``,
541
``BzrDir.has_workingtree``, ``Repository.get_physical_lock_status``,
542
``Branch.get_physical_lock_status``,

``Repository.all_revision_ids``, ``Repository.start_write_group``,
547
``Repository.commit_write_group``, ``Repository.abort_write_group``
548
``Repository.check_write_group``, ``Repository.iter_revisions``,
549
``Repository.add_signature_revision_text`` and
550
``Repository.get_revision_signature_text``.
553
* ``RemoteBranch.get_config_stack`` and ``RemoteBzrDir.get_config_stack``
554
will now use HPSS calls where possible. (Jelmer Vernooij)
556
* The registry of merge types has been moved to ``merge`` from ``option`` but
557
``merge.get_merge_type_registry`` remains as an accessor. (Martin Packman)
562
* Avoid failures in test_transform when OS error messages are localised.
563
(Martin Packman, #891582)
565
* Tests are now subject to a time limit: by default 300s, and 120s when
566
run from 'make check', controlled by the `selftest.timeout`
567
configuration option. This is currently not supported on Windows.
575
This is the third beta of the 2.5 series, leading to a 2.5.0 release in
576
February 2012. Beta releases are suitable for everyday use but may cause
577
some incompatibilities with plugins.
579
This release includes log options for ``push`` and ``pull``, more UI polish

587
*****************************
594
* The ``log_format`` configuration can be used with ``-Olog_format=line`` to
595
change the format ``push`` and ``pull`` use to display the
596
revisions. I.e.: ``bzr pull -v -Olog_format=short`` will use the ``short``
597
format instead of the default ``long`` one. (Vincent Ladeuil, #861472)
599
* The new config scheme allows an alternative syntax for the 'appenpath'
600
policy relying on option expansion and defining a new 'relpath' option
601
local to a section. Instead of using '<option>:policy=appendpath', the
602
option value can de defined as 'option=xxxx/{relpath}'.
603
(Vincent Ladeuil, #832013)
608
* ``bzr info -v`` now shows the number of colocated branches
609
for control directories that support them.
610
(Jelmer Vernooij, #863285)
612
* ``bzr version-info`` now takes a ``--revision`` argument.
613
(Jelmer Vernooij, #238705)
615
* ``bzr revno`` now takes a ``--revision`` argument.
616
(Jelmer Vernooij, #870649)
618
* ``bzr serve`` now can serve from URLs rather than just from the
619
file system. I.e.: ``bzr serve -d lp:bzr`` or
620
``bzr serve -d file:///data/bzr`` (Jelmer Vernooij)
622
* all input prompts are now char-based when possible, and can be forced to
623
line-based mode by setting the ``BZR_TEXTUI_INPUT`` environment variable
624
to 'line-based'. This replace the previous shelf UI only patch using
625
``INSIDE_EMACS``. (Benoît Pierre)
630
* ``bzr info`` now shows the master branch location too for
631
treeless local branches. (Jelmer Vernooij, #258355)
633
* ``bzr mkdir --quiet`` now does not print a line for every created
634
directory. (Martin von Gagern, #869915)
636
* ``bzr mv`` does not crash when attempting to move the root of a
637
branch. (Jonathan Riddell, #809728)
639
* ``bzr shelve`` now use ``UIFactory.choose`` for input handling, making
640
it usable when creating a custom ``UIFactory`` implementation. (Benoît
643
* ``bzr clean-tree`` now use ``UIFactory.get_boolean`` for confirmation
644
prompt, making it usable when using a custom ``UIFactory``
645
implementation. (Benoît Pierre)
647
* If sending a crash through Apport fails report the Apport failure to
648
bzr.log rather than stderr. (Jonathan Riddell, #766735)

* ``bzr upgrade`` no longer treats 'already up-to-date' exceptions as
651
errors. (Benoît Pierre, #716560).
653
* ``bzr version-info`` no longer populates the clean state for custom
654
templates unless {clean} is explicitly asked for.
655
(Lawrence Mitchell, #882541)
657
* Fix finding the CPU count when using Python >= 2.6 on BSD-based systems.
658
(Jelmer Vernooij, #887151)
660
* ``WorkingTree.clone()`` now supports its ``revision_id`` being set
661
to the null revision. (Jelmer Vernooij, #876423)
663
* ``WorkingTree.pull`` can now pull ``NULL_REVISION``.
664
(Jelmer Vernooij, #887556)
669
* ``Branch.revision_history`` is now deprecated. (Jelmer Vernooij, #799519)
671
* Methods ``add`` and ``items`` of ``LRUCache`` and ``LRUSizeCache`` are
672
deprecated. Use normal dict-style access instead. (Martin Packman)
674
* New flag ``RepositoryFormat.supports_unreferenced_revisions`` which
675
indicates whether revisions can be present in a repository without
676
being referenced from e.g. a branch history at the same time.
679
* ``UIFactory.choose`` has been added: prompt the user for a list of
680
choices. (Benoît Pierre)
685
* ``ControlDirFormat`` now has a new method ``supports_transport``
686
which format implementations can use whether or not they can access
687
a control dir over a particular transport. (Jelmer Vernooij)
689
* ``BranchBuilder.build_commit`` now take ``parent_ids`` and
690
``allow_leftmost_as_ghost`` arguments. (Jelmer Vernooij)
695
* Ensure TestCase instances are deallocated immediately after running where
696
possible. This greatly reduces the peak resource needs of a full test suite
697
run. The new ``-Euncollected_cases`` selftest flag will add failures if any
698
case which persists pasts its expected lifetime. (Martin Packman, #613247)
700
* Report exceptions from child processes during fork instead of swallowing the
701
error and reporting that everything went okay. (Martin Packman, #804130)
707
This is the second beta of the 2.5 series, leading to a 2.5.0 release in
708
February 2012. Beta releases are suitable for everyday use but may cause some
709
incompatibilities with plugins.
711
This release includes more filtering options for ``bzr log``, idle
712
connections handling for ``bzr serve``, a ``development-colo`` experimental
713
format to flesh out the colocated branches UI, better support for foreign
714
formats, enhancements to the config framework and more.
716
This release includes all bug fixed in previous series known at the time of
721
External Compatibility Breaks
722
*****************************
729
* A new ``-O`` standard option (common to all commands) have been added. It
730
provides a value for a config option in the ``-Oname=value`` form that
731
takes precedence over all definitions found in config files. It can be
732
used multiple times to override different options.
733
(Vincent Ladeuil, #491196)
735
* ``bzr log`` now has an option called ``--omit-merges`` to omit
736
those commits that merged branches, i.e. those having more than one
738
In order to avoid confusion, the previous command line option
739
``--include-merges`` has been renamed to ``--include-merged``.
740
The old name of the command line option will still be accepted.
741
The name change also affects ``bzr missing``.
744
* ``bzr serve`` will now disconnect clients if they have not issued an RPC
745
request after 5minutes. On POSIX platforms, this will also happen for
746
``bzr serve --inet``. This can be overridden with the configuration
747
variable ``serve.client_timeout`` or in the command line parameter
748
``bzr serve --client-timeout=X``. Further, it is possible to request
749
``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will
750
finish the current request, and then close the connection.
751
(John Arbash Meinel, #824797, #795025)
753
* The new experimental format ``development-colo`` supports colocated
754
branches. This format will eventually be merged back into the ``2a``
755
format when it has stabilized and there is adequate UI support for
757
(Jelmer Vernooij, #831481)
762
* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
763
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)
765
* ``bzr info -v`` can now be run against branches that don't support
766
``last_revision_info``, in which case the branch information will simply
767
not be displayed. (Jelmer Vernooij)
772
* ``bzr shelve`` can now be used in emacs shells as the input handling is
773
turned into a line-based one when ``INSIDE_EMACS`` is set (which is the
774
case for all recent emacs versions). (Vincent Ladeuil, #856261)
776
* ``bzr tags`` can now be used against remote repositories that do
777
not provide access to the revision graph. (Jelmer Vernooij, #858942)
779
* ``bzr update PATH`` will stop if you seem to be asking it to update
780
anything less than a whole tree, because that's not supported by ``bzr``'s
781
concept that the whole tree has a single basis revision. Previously, it
782
would go ahead and update the whole tree, which was surprising.
783
(Martin Pool, #557886)
785
* Don't crash if ``bzrlib.initialize()`` has not been called while accessing
786
configs. (Vincent Ladeuil, #863401)
788
* Redirects between http and https no longer discard path information
789
in some cases. (Jelmer Vernooij, #853765)
791
* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer
792
reports all tags as changed. (Jelmer Vernooij, #845396)
794
* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is
795
specified that is unknown. (Jelmer Vernooij, #847435)
801
* ``Branch.get_revision_delta`` has been deprecated. Use
802
``Repository.get_revision_delta`` instead. (Jelmer Vernooij, #859712)
804
* Plugins that implement custom protocols for ``bzr serve`` should now
805
also take an argument ``timeout``. This is used by the the bzr protocol
806
to close a connection if a client has been idle for more than X seconds.
807
(Default 5minutes). (John Arbash Meinel)
809
* ``Repository.fileids_altered_by_revision_ids`` has been moved to
810
``VersionedFileRepository`` and is no longer part of the standard
811
``Repository`` interface. (Jelmer Vernooij)
813
* The argument ``include_merges`` to ``missing.find_unmerged`` has
814
been renamed to ``include_merged``. The old name is still supported
815
for now but will cause a deprecation warning. (Martin von Gagern)
817
* The new method ``ControlDirFormat.is_initializable()`` returns a boolean
818
indicating whether or not it is possible to use any of the
819
initialization methods of that format to create a new control dir.
825
* ``Branch`` objects can now use a config stack with the newly introduced
826
``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can
827
be used for the same branch but it's recommended to stick to one for a
833
* Test scripts can now use ``bzr shelve`` and provide their input as
834
complete lines. (Vincent Ladeuil, #856261)
836
* Really corrupt the pack file without depending on a special length or value.
837
(Vincent Ladeuil, #807032)
845
This is the first beta of the 2.5 series, leading up to a 2.5.0
846
release in February 2012.
848
This release includes better support for gpg signing, better support for
849
i18n (mostly command help and error messages), more options to filter ``bzr
850
log`` output, more support for colocated branches ("location,branch=XXX"
851
syntax), better feedback on updated tags for various commands, faster
852
branching into an empty repository, enhancements to the config framework and
855
Beta releases are suitable for everyday use but may cause some
856
incompatibilities with plugins. Some plugins may need small updates to work
859
External Compatibility Breaks
860
*****************************
867
* A ``from_unicode`` parameter can be specified when registering a config
868
option. This implements boolean, integer and list config options when the
869
provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``
870
are used for this parameter. (Vincent Ladeuil)
872
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
873
checks to see if the most recent published source package version for
874
that project is present in the branch tags. This should help developers
875
trust whether the packaging branch is up-to-date and can be used for new
876
changes. The level of verbosity is controlled by the config item
877
``launchpad.packaging_verbosity``. It can be set to one of
884
only display if the branch is out-of-date
887
also display single-line up-to-date and missing,
891
(default) display multi-line content for all states
894
(John Arbash Meinel, #609187, #812928)
896
* Add a config option gpg_signing_key for setting which GPG key should
897
be used to sign commits. Also default to using the gpg user identity
898
which matches user_email() as set by whoami.
899
(Jonathan Riddell, #68501)
901
* An ``invalid`` parameter can be specified when registering a config option
902
to decide what should be done when invalid values are
903
encountered. 'warning' and 'error' will respectively emit a warning and
904
ignore the value or errors out. (Vincent Ladeuil)
906
* bzr add now skips large files in recursive mode. The default "large"
907
size is 20MB, and is configurable via the add.maximum_file_size
908
option. A value of 0 disables skipping. Named items passed to add are
909
never skipped. (Shannon Weyrick, #54624)
911
* ``bzr help configuration/<option>`` display the help for ``option`` for
912
all registered configuration options. (Vincent Ladeuil, #747050)
914
* ``bzr log -m`` now matches message, author, committer and bugs instead
915
of just matching the message. ``--message`` keeps its original meaning,
916
while ``--match-message, --match-author, --match-committer`` and
917
``--match-bugs`` match each of those fields. (Jacek Sieka)
919
* ``config.Option`` can now declare ``default_from_env``, a list of
920
environment variables to get a default value from. (Vincent Ladeuil)
922
* ``config.NameMatcher`` can be used to implement config stores and stacks
923
that need to provide specific option values for arbitrary unique IDs (svn
924
repository UUIDs, etc). (Vincent Ladeuil, #843638)
926
* New builtin ``bzr branches`` command, which lists all colocated branches
927
in a directory. (Jelmer Vernooij, #826820)
929
* Relative local paths can now be specified in URL syntax by using the
930
"file:" prefix. (Jelmer Vernooij)
932
* Report commits signed with expired keys in ``verify-signatures``.
933
(Jonathan Riddell, #804254)
935
* Translations are now enabled for command help, errors and globally
936
for any message using ``gettext`` given on output. (Jonathan Riddell,
942
* ``bzr add`` will now warn about nested subtrees that are skipped.
943
(Jelmer Vernooij, #187342)
945
* ``bzr commit -m ''`` can now be used to force an empty commit message.
946
Entering an empty commit message in the message editor still triggers
947
an error. (Jelmer Vernooij)
949
* ``bzr pull`` will now mention how many tags it has updated.
950
(Jelmer Vernooij, #164450)
952
* ``bzr tag`` no longer errors if a tag already exists but refers to the
953
same revision, and will mention when a tag has been updated
954
rather than created. (Jelmer Vernooij, #381203)
956
* ``bzr uncommit`` will now remove tags that refer to removed revisions.
957
The ``--keep-tags`` option can be used to prevent this behaviour.
958
(Jelmer Vernooij, #605814)
960
* Do not run i18n initialisation twice. (Jonathan Riddell)
962
* Install translation .mo files. (Jonathan Riddell)
964
* Locations printed by ``bzr upgrade`` are now formatted before display.
967
* ``Repository.get_parent_map`` now estimates the size of the returned
968
content more accurately. This means that we get closer to the desired
969
64kB/request. For repositories converted from svn, this can be an
970
improvement of approx 5:1 in round trips to discover the whole history.
973
* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
974
if no bug tracker was specified on the command line.
975
(Jelmer Vernooij, #334860)
977
* Use ``gettext.NullTranslations`` in i18n to allow use of i18n even when
978
translations are not turned on. (Jonathan Riddell)
983
* ``bzr commit`` now correctly reports missing files as "removed", not
984
"modified". (Jelmer Vernooij, #553955)
986
* ``bzr reconfigure`` will now allow multiple non-conflicting requests
987
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
988
(Martin von Gagern, #842993)
990
* A call to CHKInventory's filter-method will not result in a
991
DuplicateFileId error, if you move a subfolder and change a file in
993
(Bastian Bowe, #809901)
995
* Branching from a stacked branch no longer does a ``get_parent_map``
996
request for each revisions that is in the stacked-on repository while
997
determining what revisions need to be fetched. This mostly impacts
998
branching initialy into an empty shared repository when the source is
999
not the development focus. (John Arbash Meinel, #388269)
1001
* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
1002
errors. (Vincent Ladeuil, #822571)
1004
* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
1005
raised whenever a transport at the drive root was opened on windows.
1006
(Martin [gz], #841322)
1008
* Fixed loading of external merge tools from config to properly decode
1009
command-lines which contain embedded quotes. (Gordon Tyler, #828803)
1011
* Rather than an error being raised, a warning is now printed when the
1012
current user does not have permission to read a configuration file.
1013
(Jelmer Vernooij, #837324)
1015
* The pull command will now always use separate connections for the
1016
case where the destination is a heavyweight checkout of some remote
1017
branch on the same host as the source branch.
1018
(Martin von Gagern, #483661)
1020
* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
1021
operations that use it, like merge, can now create trees without a root.
1027
* Release instructions refreshed. (Vincent Ladeuil)
1032
* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
1033
argument. (Jelmer Vernooij)
1035
* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
1036
which indicates if the format should be for a lightweight or a
1037
heavyweight checkout. (Jelmer Vernooij)
1039
* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
1042
* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
1045
* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
1046
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
1049
* New method ``InterTree.file_content_matches`` which checks that
1050
two files in different trees have the same contents.
1053
* New method ``Tree.get_file_verifier`` which allows tree implementations
1054
to return non-sha1 checksums to verify files.
1055
(Jelmer Vernooij, #720831)
1057
* New methods ``get_transport_from_path`` and ``get_transport_from_url``
1058
have been added that only support opening from a path or a URL,
1059
unlike ``get_transport``. (Jelmer Vernooij)
1061
* New registry ``OptionRegistry`` specialized for configuration options.
1064
* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
1067
* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
1068
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
1069
2.10 and 2.2.0. (Vincent Ladeuil)
1071
* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.
1073
* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
1074
``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
1075
remove ``log.show_one_log`` which was never properly deprecated but wasn't
1076
used and is easy to inline if needed. (Vincent Ladeuil)
1078
* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
1079
deprecated in 2.1.0. (Vincent Ladeuil)
1081
* Remove ``TransportListRegistry.set_default_transport``, as the concept of
1082
a default transport is currently unused. (Jelmer Vernooij)
1084
* Remove ``UIFactory.warn_cross_format_fetch`` and
1085
``UIFactory.warn_experimental_format_fetch`` in favor of
1086
``UIFactory.show_user_warning``. (Jelmer Vernooij)
1088
* ``Tags`` containers can now declare whether they support versioned
1089
tags and whether tags can refer to ghost tags.
1092
* ``Tags.merge_to`` now returns a dictionary with the updated tags
1093
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)
1095
* There is a new class `ContentFilterTree` that provides a facade for
1096
content filtering. The `filtered` parameter to `export` is deprecated
1097
in favor of passing a filtered tree, and the specific exporter plugins
1098
no longer support it.
1101
* ``Transport`` now has a ``_parsed_url`` attribute instead of
1102
separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
1103
and ``_path`` attributes. Proxies are provided for the moment but
1104
may be removed in the future. (Jelmer Vernooij)
1109
* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
1110
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
1111
is attempted. (Jelmer Vernooij)
1113
* New method ``ControlDir._get_selected_branch`` which returns the
1114
colocated branch selected using path segment parameters.
1115
(Jelmer Vernooij, #380871)
1120
* Blackbox tests (including test scripts) can be debugged interactively (see
1121
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)
1123
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
1124
cleanly and reliably allows tests using `BranchBuilder` to construct
1125
branches that e.g. rename files out of a directory and unversion that
1126
directory in the same revision. Previously some changes were impossible
1127
due to the order that `build_snapshot` performs its actions.
1130
* Don't require ``os.fdatasync`` to be defined on all supported OSes
1131
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)
1133
* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
1135
* ``LockDir`` can now be run when the local hostname is ``localhost``.
1136
(Jelmer Vernooij, #825994)
1138
* ``ModuleAvailableFeature`` won't try to import already imported modules,
1139
allowing it to be used for modules with side-effects.
1140
(Vincent Ladeuil, #712474)
1142
* Output time stamps while running ``make check`` to get better timings from
1143
pqm. (Vincent Ladeuil, #837926)
1145
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
1146
just compares the bytes in the dirstate file to its pristine state,
1147
rather than opening the WorkingTree and calling ``last_revision()``.
1148
This reduces the overall test suite time by about 10% on my laptop.
1151
* Update `TestCase.knownFailure` to the testtools way of handling expected
1152
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
