.. These may require users to change the way they use Bazaar.
21
.. New commands, options, etc that users may wish to try out.
26
.. Improvements to existing commands, especially improved performance
27
or memory usage, or better results.
32
.. Fixes for situations where bzr would previously crash or give incorrect
33
or undesirable results.
35
* ``config.LocationMatcher`` properly excludes unrelated sections.
36
(Vincent Ladeuil, #829237)
38
* ``dirstate.fdatasync`` and ``repository.fdatasync`` can now properly be
39
disabled. (Vincent Ladeuil, #824513)
41
* Fix i18n use when no environment variables are set. (Jelmer Vernooij, #810701)
46
.. Improved or updated documentation.
48
* Corrected documentation for BZR_PROGRESS_BAR.
49
(Dennis Benzinger, #735417)
54
.. Changes that may require updates in plugins or other code that uses
60
.. Major internal changes, unlikely to be visible to users or plugin
61
developers, but interesting for bzr developers.
66
.. Fixes and changes that are only relevant to bzr's test framework and
67
suite. This can include new facilities for writing tests, fixes to
68
spurious test failures and changes to the way things should be tested.
76
This release marks the start of a new long-term-stable series. From here, we
77
will only make bugfix releases on the 2.4 series (2.4.1, etc, and support it
78
until February 2013), while 2.5 will become our new development series.
80
This is a bugfix and polish release over the 2.3 series, with a large number
81
of bugs fixed (>150 for the 2.4 series alone), and some performance
82
improvements. Support for python 2.4 and 2.5 has been dropped, many large
83
working tree operations have been optimized as well as some stacked branches
86
Only bugfixes from other stables series have been included since 2.4b5 so
87
all known fixed bugs are included here.
89
Users are encouraged to upgrade from the other stable series.

114
* A call to CHKInventory's filter-method will not result in a
115
DuplicateFileId error, if you move a subfolder and change a file in
117
(Bastian Bowe, #809901)
119
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
120
checks to see if the most recent published source package version for
121
that project is present in the branch tags. This should help developers
122
trust whether the packaging branch is up-to-date and can be used for new
123
changes. The level of verbosity is controlled by the config item
124
``launchpad.packaging_verbosity``. It can be set to one of
131
only display if the branch is out-of-date
134
also display single-line up-to-date and missing,
138
(default) display multi-line content for all states
141
(John Arbash Meinel, #609187, #812928)
143
* Cope with not all Python versions having a ``clear`` method on
144
``TestCase._type_equality_funcs``.
145
(Martin [gz], Jelmer Vernooij, #809048)
147
* Fetching tags when fetching the tip revision of a branch is now
148
controlled by the config setting ``branch.fetch_tags``. The behavior has
149
been reverted to 2.3's not-fetching tagged revisions by default.
150
(John Arbash Meinel, #771184)
152
* The fix for bug #513709 caused us to open a new connection when
153
switching a lightweight checkout that was pointing at a bound branch.
154
This isn't necessary because we know the master URL without opening it,
155
avoiding an extra SSH connection, etc.
156

.. Fixes and changes that are only relevant to bzr's test framework and
180
suite. This can include new facilities for writing tests, fixes to
181
spurious test failures and changes to the way things should be tested.
183
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
184
cleanly and reliably allows tests using `BranchBuilder` to construct
185
branches that e.g. rename files out of a directory and unversion that
186
directory in the same revision. Previously some changes were impossible
187
due to the order that `build_snapshot` performs its actions.
190
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
191
just compares the bytes in the dirstate file to its pristine state,
192
rather than opening the WorkingTree and calling ``last_revision()``.
193
This reduces the overall test suite time by about 10% on my laptop.
202
This is the fifth (and last) beta of the 2.4 series leading to
203
2.4.0 release in August 2011. Beta releases are suitable for
204
everyday use but may cause some incompatibilities with plugins.
206
This release includes all bug fixed in previous series known at
207
the time of this release.

*****************************
217
* New command ``verify-signatures`` to check if all commits or specified commits
218
have digital signatures from trusted keys. Requires python-gpgme to be
221
* New option ``--signatures`` for ``bzr log`` to display digital signature
222
verification results for each commit.
224
* Config option acceptable_keys to list which GPG keys are verified as trusted.
226
* Config option validate_signatures_in_log to always show signatures in
232
* ``Branch.open`` is now about 3x faster (about 2ms instead of 6.5ms).
235
* Pack, dirstate, and index files are synced to persistent storage if
236
possible when writing finishes, to reduce the risk of problems caused by
237
a machine crash or similar problem. This can be turned off through the
238
``dirstate.fdatasync`` and ``repository.fdatasync`` options, which can
239
be set in ``locations.conf`` or ``bazaar.conf``. (Martin Pool,
245
* Display a proper error message when a config file content cannot be
246
decoded as UTF-8 or when it cannot be parsed.
247
(Vincent Ladeuil, #502060, #688677, #797246)
249
* Generate a single conflict (instead of two) when merging a branch
250
modifying and renaming a file in a branch that deleted it (or vice-versa).
251
(Vincent Ladeuil, #688101)
253
* Give a more helpful message when the bzr executable doesn't match the
254
library. (This typically happens because of a misconfigured PYTHONPATH
255
or half-installed bzr.)
256
(Martin Pool, #804553)
258
* Properly load utf8-encoded config files. (Vincent Ladeuil, #799212)
260
* ``GraphThunkIdsToKeys.merge_sort`` now properly returns
261
keys rather than ids. (Jelmer Vernooij, #799677)
263
* ``TreeTransformBase.fixup_new_roots`` can now check that a tree root
264
is present. (Jelmer Vernooij, #801257)
269
* New attributes ``WorkingTreeFormat.supports_versioned_directories`` and
270
``RepositoryFormat.supports_versioned_directories``.
271
(Jelmer Vernooij, #765815)
273
* The "revno" field type when using the python version-info format is now
274
a string (to handle dotted revnos) (Benoît Pierre, #796259)
279
* Start implementing localization, starting with command help text (but not
280
the command options themselves). This will allow bootstrapping the bzr
281
internationalization process. (Inada Naoki)
286
* Fix test failures when running as a homeless user (debian buildd). Tests
287
leaking into ``${HOME}/.bzr.log`` should be detected properly now.

306
.. These may require users to change the way they use Bazaar.
308
* Do not treat configuration option 'check_signatures = require' as if
309
it were 'create_signatures = always' (Jonathan Riddell)
314
.. New commands, options, etc that users may wish to try out.
316
* Hooks have been added for config stacks: ``get``, ``set`` and ``remove``
317
are called when an option is respectively read, modified or deleted. Also
318
added ``load`` and ``save`` hooks for config stores, called when the
319
stores are loaded or saved. (Vincent Ladeuil)
321
* New hook server_exception in bzrlib.smart.server to catch any
322
exception caused while running bzr serve.
323
(Jonathan Riddell, #274578)
325
* New hook set_commit_message in bzrlib.msgeditor to set a commit message
326
and revision properties. (Jonathan Riddell, #274578)
328
* Support ``-S`` as an alias for ``--short`` for the ``log`` and
329
``missing`` commands. (Martin von Gagern, #38655)
334
.. Improvements to existing commands, especially improved performance
335
or memory usage, or better results.
337
* ``bzr annotate`` can be run without setting whoami data first.
338
(Jonathan Riddell, #667408)
343
.. Fixes for situations where bzr would previously crash or give incorrect
344
or undesirable results.
346
* Bazaar can now detect when a lock file is held by a dead process
347
originating from the same machine, and steal the lock after printing a
348
message to the user. This is off by default, for safety, but can be
349
turned on by setting the configuration variable ``locks.steal_dead`` to
351
(Martin Pool, #220464)
353
* ``bzr version-info`` now works when the tree is on a dotted revno.
354
(Benoît Pierre, #796259)
356
* Credentials in the log output produced by ``-Dhttp`` are masked so users
357
can more freely post them in bug reports. (Vincent Ladeuil, #723074)
359
* Fix a race condition for ``server_started`` hooks leading to a spurious
360
test failure. (Vincent Ladeuil, #789167)
362
* Fix exporting subdirectory with ``--per-file-timestamps``.
363
(Szilveszter Farkas, #795557)
365
* Handle files that get created but don't get used during TreeTransform.
366
``open()`` can create a file, and still raise an exception before it
367
returns. So anything we might have created, make sure we destroy during
368
``finalize()``. (Martin [gz], #597686)
370
* ``pack_repo`` now uses ``Transport.move`` instead of
371
``Transport.rename``, deleting any existing targets even on SFTP.
372
(Martin von Gagern, #421776)
374
* Pass the ``build_mo`` command to the rest of the setup() calls in
375
setup.py. The ``bdist_wininst`` and ``py2exe`` code paths were failing
376
because ``build_mo`` became a required step that they didn't know about.
377
(John Arbash Meinel, #787122)
379
* Preserve existing ``root-id`` when merging an unrelated branch.
380
(Aaron Bentley, #806356)
382
* Properly avoid re-adding a file after it changes case on CICP
383
filesystems. (John Arbash Meinel, #798130)
385
* Reports the original error when an InvalidHttpResponse exception is
386
encountered to facilitate debug. (Vincent Ladeuil, #788530)
388
* Reports a non-existent file error when trying to merge in a file
389
that does not exist. (Jonathan Riddell, #330063)
391
* ``UIFactory.prompt``, ``UIFactory.get_username``,
392
``UIFactory.get_password`` and ``UIFactory.get_boolean`` now require a
393
unicode prompt to be passed in. (Jelmer Vernooij, #592083)
395
* Support merging into the empty tree. (Aaron Bentley, #595328)
400
.. Improved or updated documentation.
402
* Improve documentation of ``bzr merge --force``.
403
(Neil Martinsen-Burrell, #767307)
405
* Make docs for configuration options for digital signatures match
406
reality. (Jonathan Riddell)
408
* Add user-guide page on GPG signatures. (Jonathan Riddell)
413
.. Changes that may require updates in plugins or other code that uses
416
* Checking for a file id in a `Tree` or `Inventory` using ``in`` is now
417
deprecated. Instead, use `has_id`.
420
* Exporters are now all exposed as generators, rather than as single-call
421
functions, so that calling code can take stream the output.
424
* Information about held lockdir locks returned from eg `LockDir.peek` is
425
now represented as a `LockHeldInfo` object, rather than a plain
429
* Remove `file_status` function.
432
* ``Repository.iter_reverse_revision_history`` is now deprecated.
433
Use ``Graph.iter_lefthand_ancestry`` instead.
434
(Jelmer Vernooij, #739481)
436
* ``Repository.get_ancestry`` has been deprecated. Use
437
``Graph.iter_ancestry`` instead.
438
(Jelmer Vernooij, #784511)
443
.. Major internal changes, unlikely to be visible to users or plugin
444
developers, but interesting for bzr developers.
446
* ``tools/check-newsbugs.py`` accepts a ``--browser`` option to open
447
corresponding launchpad pages in a browser. (Vincent Ladeuil)
452
.. Fixes and changes that are only relevant to bzr's test framework and
453
suite. This can include new facilities for writing tests, fixes to
454
spurious test failures and changes to the way things should be tested.
456
* A `ImportTariffTestCase` base class has been added in
457
``bzrlib.tests.test_import_tariff``, which can be used for import tariff
458
tests in plugins. (Jelmer Vernooij, #793465)
460
* Fix deadlock in `TestImportTariffs.test_simple_serve` when stderr gets
461
more output than fits in the default buffer. This was happening on the
462
Windows buildslave, and could easily happen in other circumstances where
463
the default OS buffer size for pipes is small or the ``python -v``
464
output is large. (Andrew Bennetts, #784802)
466
* Fix spurious test failure on OSX for WorkingTreeFormat2.
467
(Vincent Ladeuil, #787942)
469
* Re-target ``bb.test_merge.TestMerge.test_merge_reversed_revision_range``
470
and rewrite it as a parametrized test to avoid unrelated failures.
471
(Vincent Ladeuil, #795456)
473
* Show log file contents from subprocesses started by
474
`start_bzr_subprocess` in test failure details. This may help diagnose
475
strange hangs and failures involving subprocesses. (Andrew Bennetts)
477
* Skip ``utextwrap`` tests when ``sphinx`` breaks text_wrap by an hostile
478
monkey-patch to textwrap.TextWrapper.wordsep_re.
479
(Vincent Ladeuil, #785098)
481
* Multiple ``selftest --exclude`` options are now combined instead of
482
overriding each other. (Vincent Ladeuil, #746991)
484
* Restore some ``FTPTransport`` test coverage by allowing ``pyftpdlib
485
0.6.0`` to be used. Also restore ``medusa`` support while leaving it
486
disabled to make it easier to use if/when we can in the future.
487
(Vincent Ladeuil, #781140)
489
* `TestImportTariffs` no longer uses the real ``$HOME``. This prevents it
490
from polluting ``$HOME/.bzr.log`` or being accidentally influenced by
491
user configuration such as aliases. It still runs with all the user's
492
plugins enabled, as intended.
493

*****************************
512
.. These may require users to change the way they use Bazaar.
514
* ``bzr-2.4`` has officially dropped support for python2.4 and python2.5.
515
We will continue to maintain ``bzr-2.3`` for people who still need to
516
use those versions of python. (John Arbash Meinel)
521
.. New commands, options, etc that users may wish to try out.
523
* The text compressor used for 2a repositories now has a tweakable
524
parameter that can be set in bazaar.conf.
525
``bzr.groupcompress.max_entries_per_source`` default of 65536.
526
When doing compression, we build up an index of locations to match
527
against. Setting this higher will result in slightly better compression,
528
at a cost of more memory. Note that a value of 65k represents fully
529
sampling a 1MB file. So this only has an effect when compressing texts
530
larger than N*16 bytes. (John Arbash Meinel, #602614)
535
.. Improvements to existing commands, especially improved performance
536
or memory usage, or better results.
538
* ``bzr branch --stacked`` from a smart server uses the network a little
539
more efficiently. For a simple branch it reduces the number of
540
round-trips by about 20%. (Andrew Bennetts)
542
* ``bzr log --line`` scales the width of the author field with the size of
543
the line. This means that the full author name is shown when the
544
environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)
546
* ``bzr pull`` now properly triggers the fast
547
``CHKInventory.iter_changes`` rather than the slow generic
548
inter-Inventory changes. It used to use a ``DirStateRevisionTree`` as
549
one of the source trees, which is faster when we have to read the whole
550
inventory anyway, but much slower when we can get just the delta out of
551
the repository. On a 70k record tree, this changes ``bzr pull`` from 28s
552
down to 17s. (John Arbash Meinel, #780677)
554
* Slightly reduced memory consumption when fetching into a 2a repository
555
by reusing existing caching a little better. (Andrew Bennetts)
557
* Speed up ``bzr status`` by a little bit when there are a couple of
558
modified files. We now track how many files we have seen that need
559
updating, and only rewrite the dirstate file if enough of them have
560
changed. The default is 10, and can be overridden by setting the branch
561
option "``bzr.workingtree.worth_saving_limit``".
562
(Ian Clatworthy, John Arbash Meinel, #380202)
564
* Speed up ``bzr uncommit``. Instead of resetting the dirstate from
565
scratch, use ``update_basis_by_delta``, computing the delta from the
566
repository. (John Arbash Meinel, #780544)
571
.. Fixes for situations where bzr would previously crash or give incorrect
572
or undesirable results.
574
* All Tree types can now be exported as tar.*, zip or directories.
577
* ``bzr merge --no-remember location`` never sets ``submit_branch``.
578
(Vincent Ladeuil, #782169)
580
* ``bzr pull --no-remember location`` never sets
581
``parent_location``. ``bzr push --no-remember location`` never
582
sets ``push_location``. ``bzr send --no-remember
583
submit_location public_location`` never sets ``submit_branch``
584
nor ``public_branch``. (Vincent Ladeuil)
586
* Conflicts involving non-ascii filenames are now properly reported rather
587
than failing with a UnicodeEncodeError. (Martin [GZ], #686161)
589
* Correct parent is now set when using 'switch -b' with bound branches.
590
(A. S. Budden, #513709)
592
* Fix `bzr plugins` regression in bzr 2.4 which resulted in a traceback
593
from writelines on ckj terminals. (Martin [GZ], #754082)
595
* ``WT.inventory`` and ``WT.iter_entries_by_dir()`` was not correctly
596
reporting subdirectories that were tree references (in formats that
597
supported them). (John Arbash Meinel, #764677)
599
* Merging into empty branches now gives an error as this is currently
600
not supported. (Jonathan Riddell, #242175)
602
* Do not show exception to user on pointless commit error.
603
(Jonathan Riddell #317357)
605
* ``WT.update_basis_by_delta`` no longer requires that the deltas match
606
the current WT state. This allows ``update_basis_by_delta`` to be used
607
by more commands than just commit. Updating with a delta allows us to
608
not load the whole inventory, which can take 10+s with large trees.
609
(Jonathan Riddell, John Arbash Meinel, #781168)
611
* ``bzr mv --after old_name new_name`` now works if "new_name" is newly
612
added. (Benoît Pierre)
618
.. Improved or updated documentation.
620
* Restore the workaround for option names including dots (--1.14) which was
621
disabled when we stopped listing --1.9 as a format.
622
(Vincent Ladeuil, #782289)
627
.. Changes that may require updates in plugins or other code that uses
630
* ``annotate_file`` has been deprecated in favor of
631
``annotate_file_revision_tree``. (Jelmer Vernooij, #775598)
633
* ``Branch.fetch`` now takes an optional ``limit`` argument.
634
(Andrew Bennetts, Jelmer Vernooij, #750175)
636
* ``Inter.get`` now raises ``NoCompatibleInter`` if there are no
637
compatible optimisers rather than an instance of the class it is called
638
on. (Jelmer Vernooij)
640
* ``Branch.push`` now takes a ``lossy`` argument.
641
``Branch.lossy_push`` has been removed.
644
* New method ``Repository.get_file_graph`` which can return the
645
per-file revision graph. (Jelmer Vernooij, #775578)
647
* The default implementation of ``Branch`` is now oriented to
648
storing the branch tip. Branch implementations which store the full
649
history should now subclass ``FullHistoryBzrBranch``.
650
``Branch._last_revision_info`` has been renamed to
651
``Branch._read_last_revision_info`` (Jelmer Vernooij)
653
* ``Tree.__iter__`` has been deprecated; use ``Tree.all_file_ids``
654
instead. (Jelmer Vernooij)
656
* ``Tree.get_symlink_target`` now takes an optional ``path``
657
argument. (Jelmer Vernooij)
662
.. Major internal changes, unlikely to be visible to users or plugin
663
developers, but interesting for bzr developers.
665
* ``MutableTree.smart_add`` now uses inventory deltas.
666
(Jelmer Vernooij, #146165)
668
* Removed ``bzrlib.branch._run_with_write_locked_target`` as
669
``bzrlib.cleanup`` provides the same functionality in a more general
670
way. (Andrew Bennetts)
675
.. Fixes and changes that are only relevant to bzr's test framework and
676
suite. This can include new facilities for writing tests, fixes to
677
spurious test failures and changes to the way things should be tested.
679
* A test that was expected to fail but passes instead now counts as a failure
680
catching up with new testtools and subunit handling. (Martin [GZ], #654474)
682
* Make it easier for plugins to reuse the per_workingtree scenarios by
683
restoring the wt_scenarios helper that was accidentally deleted.
684
(Vincent Ladeuil, #783472)
686
* Removed ``test_breakin`` tests that were excessively prone to hanging,
687
did not work on Wine, and partly already disabled.

* Windows locations are different and should be tested accordingly.

This is the second beta of the 2.4 series, leading to a 2.4.0 release in
699
August 2011. Beta releases are suitable for everyday use but may cause some
700
incompatibilities with plugins.

External Compatibility Breaks
707
*****************************
709
.. These may require users to change the way they use Bazaar.
711
* Two command synonyms for ``bzr branch`` have been deprecated, to avoid
712
confusion and to allow the names to later be reused. The removed names
713
are: ``get`` and ``clone``. (Martin Pool, #506265)
718
.. New commands, options, etc that users may wish to try out.
720
* ``bzr commit`` now supports a ``--lossy`` argument that can be used
721
to discard any data that can not be natively represented when committing
722
to a foreign VCS. (Jelmer Vernooij, #587721)
727
.. Improvements to existing commands, especially improved performance
728
or memory usage, or better results.
730
* ``bzr merge`` in large trees is now significantly faster. On a 70k entry
731
tree, the time went from ~3min down to 30s. This also effects ``bzr pull``
732
and ``bzr update`` since they use the same merge logic to update the
733
WorkingTree. (John Arbash Meinel, #759091)
735
* ``bzr revert`` now properly uses ``bzr status``'s optimized
736
``iter_changes``. This can be a significant performance difference (33s
737
to 5s on large trees). (John Arbash Meinel, #759096)
739
* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
740
the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
741
being handed off to the remote server anyway (xmlrpc has been mapping
742
``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
743
than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
744
months now.) By doing it ourselves, we can cut out substantial startup
745
time. From Netherlands to London it was taking 368ms to do the XMLRPC
746
call as much as 2s from Sydney. You can test the local logic by using
747
``-Dlaunchpad``. (John Arbash Meinel, #397739)
749
* When building a new WorkingTree (such as during ``bzr co`` or
750
``bzr branch``) we now properly store the stat and hash of files that
751
are old enough. This saves a fair amount of time on the first
752
``bzr status`` (on a 500MB tree, it saves about 30+s).
753
(John Arbash Meinel, #740932)
759
.. Fixes for situations where bzr would previously crash or give incorrect
760
or undesirable results.
762
* Arguments that can't be decoded to unicode in the current posix locale give
763
a clearer error message without a traceback. (Martin [gz], #745712)
765
* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
766
mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
767
these default values aren't relied on very often so this probably
768
wasn't causing any trouble. (Andrew Bennetts)
770
* ``bzr log`` now works on revisions which are not in the current branch.
771
(Matt Giuca, #241998)
773
* Don't rewrite the dirstate file when non-interesting changes have
774
occurred. This can significantly improve 'bzr status' times when there
775
are only small changes to a large tree.
776
(Ian Clatworthy, John Arbash Meinel, #380202)
778
* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
780
* ``bzrlib.merge.Merge`` now calls ``iter_changes`` without
781
``include_unversioned=True``. This makes it significantly faster in many
782
cases, because it only looks at modified files, rather than building
783
information about all files. This can cause failures in other
784
TreeTransform code, because it had been expecting to know the names of
785
things which had not changed (such as parent directories). All cases we
786
know about so far have been fixed, but there may be fallout for edge
787
cases that we are missing. (John Arbash Meinel, #759091)
789
* ``SFTPTransport`` is more pro-active about closing file-handles. This
790
reduces the chance of having threads fail from async requests while
791
running the test suite. (John Arbash Meinel, #656170)
793
* Standalone bzr.exe installation on Windows: user can put additional python
794
libraries into ``site-packages`` subdirectory of the installation directory,
795
this might be required for "installing" extra dependencies for some plugins.
796
(Alexander Belchenko, #743256)
798
* ``transform.revert()`` has been updated to use
799
``wt.iter_changes(basis_tree)`` rather than
800
``basis_tree.iter_changes(wt)``. This allows the optimized code path to
801
kick in, improving ``bzr revert`` times significantly (33s to 4s on
802
large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)
804
* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
805
parameter. If supplied, when the transform is applied, it will then call
806
``self._tree._observed_sha1`` for those files. This lets us update the
807
hash-cache for content that we create, preventing us from re-reading the
808
content in the next ``bzr status``. (John Arbash Meinel, #740932)
813
* Added a section about using a shared SSH account on a server for bzr+ssh
814
access. (Russell Smith)
816
* The documentation now recommends using SSH rather than SFTP in the
817
tutorials and the examples, because that will generally be much faster
818
and better in cases where it can be used. SFTP is still available and
819
mentioned as an alternative. (Martin Pool, #636712)
824
.. Changes that may require updates in plugins or other code that uses
827
* ``Branch.update_revisions`` has been made private and should no
828
longer be used by external users. Use ``Branch.pull`` or ``Branch.push``
829
instead. (Jelmer Vernooij, #771765)
831
* Commands now have an `invoked_as` attribute, showing the name under
832
which they were called before alias expansion.
835
* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
838
* If you call `bzrlib.initialize` but forget to enter the resulting object
839
as a context manager, bzrlib will now be initialized anyhow.
840
(Previously simple programs calling bzrlib might find the library was
841
mysteriously silent.)
844
* Inventory-specific functionality has been split out of ``Tree`` into
845
a new ``InventoryTree`` class. Tree instances no longer
846
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
848
* Inventory-specific functionality has been split out of ``RevisionTree``
849
into a new ``InventoryRevisionTree`` class. RevisionTree instances no
850
longer necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
852
* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)
854
* ``revision_graph_can_have_wrong_parents`` is now an attribute
855
on ``RepositoryFormat`` rather than a method on ``Repository``.
858
* ``Testament`` now takes a ``tree`` rather than an
859
``inventory``. (Jelmer Vernooij, #762608)
861
* ``TestCase.failUnlessExists`` and ``failIfExists`` are deprecated in
862
favour of ``assertPathExists`` and ``assertPathDoesNotExist``
866
* The ``revno`` parameter of ``log.LogRevision`` may now be None,
867
representing a revision which is not in the current branch.
868
(Matt Giuca, #241998)
870
* The various knit pack repository format classes have been moved
871
from ``bzrlib.repofmt.pack_repo`` to
872
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)
874
* ``RevisionTree`` now has a new method ``get_file_revision``.
877
* ``WorkingTree`` no longer provides an ``inventory``. Instead,
878
all inventory-related functionality is now on the subclass
879
``InventoryWorkingTree`` that all native Bazaar working tree
880
implementations derive from. (Jelmer Vernooij)
885
.. Major internal changes, unlikely to be visible to users or plugin
886
developers, but interesting for bzr developers.
888
* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
889
functions on Linux, but they are wrapped on Windows so that fstat
890
matches lstat results across all python versions.
893
* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
894
happened to be updated as a side-effect of commit, but if we start using
895
the function elsewhere we might as well do it directly.
901
.. Fixes and changes that are only relevant to bzr's test framework and
902
suite. This can include new facilities for writing tests, fixes to
903
spurious test failures and changes to the way things should be tested.
905
* Stop using `failIf`, `failUnless`, `failIfEqual`, etc, that give
906
`PendingDeprecationWarnings` on Python2.7.
907
(Martin Pool, #760435)
915
This is the first beta of the 2.4 series, leading up to a 2.4.0
916
release in August 2011. Beta releases are suitable for everyday use
917
but may cause some incompatibilities with plugins. Some plugins may need
918
small updates to work with 2.4b1.
920
External Compatibility Breaks
921
*****************************
928
* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
929
in GNU format. See ``bzr help changelog_merge`` for details.
932
* Configuration options can now use references to other options in the same
933
file by enclosing them with curly brackets (``{other_opt}``). This makes it
934
possible to use, for example,
935
``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
936
using a loom. During the beta period, the default behaviour is to disable
937
this feature. It can be activated by declaring ``bzr.config.expand = True``
938
in ``bazaar.conf``. (Vincent Ladeuil)
940
* External merge tools can now be configured in bazaar.conf. See
941
``bzr help configuration`` for more information. (Gordon Tyler, #489915)
943
* The ``lp:`` directory service now supports Launchpad's QA staging.
944
(Jelmer Vernooij, #667483)
949
* A new hidden command ``bzr repair-workingtree``. This is a way to force
950
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
951
workaround. (John Arbash Meinel)
953
* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
954
This allows formats from plugins (such as looms) to efficiently tell the
955
client which revisions need to be fetched. (Andrew Bennetts)
957
* Branching, merging and pulling a branch now copies revisions named in
958
tags, not just the tag metadata. (Andrew Bennetts, #309682)
960
* ``bzr cat-revision`` no longer requires a working tree.
961
(Jelmer Vernooij, #704405)
963
* ``bzr export --per-file-timestamps`` for .tar.gz files will now
964
override the mtime for trees exported on Python 2.7 and later, which
965
expose the 'mtime' field in gzip files. This makes the output of
966
``bzr export --per-file-timestamps`` for a particular tree
967
deterministic. (Jelmer Vernooij, #711226)
969
* ``bzr export --format=zip`` can now export to standard output,
970
like the other exporters can. (Jelmer Vernooij, #513752)
972
* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
973
(Jelmer Vernooij, #551714)
975
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
976
sped up dramatically for large trees. Iterating by dir is not the best
977
way to load data from a CHK inventory, so it preloads all the items in
978
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
979
of CHK data, down to just 150MB.) This has noticeable affects for things
980
like building checkouts, etc. (John Arbash Meinel, #737234)
985
* A MemoryError thrown on the server during a remote operation will now be
986
usefully reported, and other unexpected errors will include the class name.
987
(Martin [gz], #722416)
989
* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
990
(Andrew King, #537442)
992
* ``bzr export`` to zip files will now set a mode on directories.
993
(Jelmer Vernooij, #207253)
995
* ``bzr export`` to tgz files will only write out the basename of the
996
tarfile to the gzip file. (Jelmer Vernooij, #102234)
998
* ``bzr push --overwrite`` with an older revision specified will now correctly
999
roll back the target branch. (Jelmer Vernooij, #386576)
1001
* ``bzr lp-propose`` can now propose merges against packaging branches on
1002
Launchpad without requiring the target branch to be specified.
1003
(Jelmer Vernooij, #704647)
1005
* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
1006
instead leave setting the reviewer up to Launchpad if it was not specified.
1007
(Jelmer Vernooij, #583772)
1009
* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
1010
(Jelmer Vernooij, #213185)
1012
* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
1013
paths, however they may still print junk if not on a UTF-8 terminal.
1014
(Martin [gz], #707954)
1016
* ``bzr reconfigure --unstacked`` now copies revisions (and their
1017
ancestors) named in tags into the unstacked repository, not just the
1018
ancestry of the branch's tip. (Andrew Bennetts, #401646)
1020
* ``bzr serve`` no longer crashes when a server_started hook is installed and
1021
IPv6 support is available on the system. (Jelmer Vernooij, #293697)
1023
* ``bzr status`` will not rewrite the dirstate file if it only has
1024
'trivial' changes. (Currently limited to dir updates and newly-added
1025
files changing state.) This saves a bit of time for regular operations.
1026
eg. ``bzr status`` in a 100k tree takes 1.4s to compute the status, but 1s
1027
to re-save the dirstate file. (John Arbash Meinel, #765881)
1029
* ``bzr tags`` will no longer choke on branches with ghost revisions in
1030
their mainline and tags on revisions not in the branch ancestry.
1031
(Jelmer Vernooij, #397556)
1033
* ``bzr whoami`` will now display an error if both a new identity and
1034
``--email`` were specified. (Jelmer Vernooij, #680449)
1036
* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
1037
(Vincent Ladeuil, #706835)
1039
* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
1041
(Martin Pool, #586341)
1043
* Plugins incompatible with the current version of bzr no longer produce a
1044
warning on every command invocation. Instead, a message is shown by
1045
``bzr plugins`` and in crash reports.
1046
(#704195, Martin Pool)
1048
* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
1049
preserves the identity of default parameter values.
1050
(Andrew Bennetts, #718569)
1052
* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
1053
containing no rows. (Eric Siegerman, #715508)
1055
* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
1056
without an explicit public location. (Max Bowsher)
1058
* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
1059
number of available processors. (Jelmer Vernooij, #693140)
1064
* Added ``Branch.heads_to_fetch`` method. Implementations of the Branch API
1065
must now inherit or implement this method. (Andrew Bennetts, #721328)
1067
* Added ``bzrlib.mergetools`` module with helper functions for working with
1068
the list of external merge tools. (Gordon Tyler, #489915)
1070
* All methods and arguments that were deprecated before 2.0
1071
have been removed. (Jelmer Vernooij)
1073
* Branch formats should now be registered on the format registry
1074
(``bzrlib.branch.format_registry``) rather than using the class
1075
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)
1077
* ``Branch.set_revision_history`` is now deprecated.
1080
* ``BranchFormat.supports_leaving_lock()`` and
1081
``RepositoryFormat.supports_leaving_lock`` flags have been added.
1084
* ``Branch.fetch`` implementations must now accept an optional
1085
``fetch_tags`` keyword argument. (Andrew Bennetts)
1087
* ``Branch.import_last_revision_info`` is deprecated. Use the
1088
``import_last_revision_info_and_tags`` method instead.
1091
* Because it was too specific to BzrDir implementations,
1092
``ControlDir.sprout`` no longer has a default implementation; it now
1093
raises ``NotImplementedError``. (Jelmer Vernooij, #717937)
1095
* ``bzrlib.deprecated_graph`` has been removed. ``bzrlib.graph``
1096
scales better tree and should be used instead.
1097
(Jelmer Vernooij, #733612)
1099
* ``ControlDirFormat.register_format`` has been removed. Instead,
1100
``Prober`` implementations should now implement a ``known_formats``
1101
method. (Jelmer Vernooij)
1103
* ControlDirFormats can now provide a ``check_status`` method and
1104
raise a custom exception or warning when an unsupported or deprecated
1105
format is being opened. (Jelmer Vernooij, #731311)
1107
* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
1108
Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
1109
``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
1110
instead. (Jelmer Vernooij, #721971)
1112
* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
1113
indicates whether the components of the bzrdir can be upgraded
1114
independent of the ``BzrDir``. (Jelmer Vernooij)
1116
* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
1117
now deprecated in favour of the ``BzrProber.formats`` format registry.
1120
* ``ControlDir`` implementations no longer have to provide the
1121
``get_branch_transport``, ``get_workingtree_transport`` and
1122
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)
1124
* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
1125
``bzrlib.controldir``. (Jelmer Vernooij)
1127
* Repository formats can now provide
1128
``_get_extra_interrepo_test_combinations`` in the same module
1129
to provide extra test combinations for ``bzrlib.tests.per_repository``.
1132
* Repository formats should now be registered on the format registry
1133
(``bzrlib.repository.format_registry``) rather than using the class
1134
methods on ``RepositoryFormat``. (Jelmer Vernooij)
1136
* Repository formats can now indicate they do not support the full
1137
VersionedFiles API by setting the ``supports_full_versioned_files``
1138
attribute to False. A subset of the VersionedFiles API
1139
(signatures and text graphs) still needs to be supported.
1142
* Repository formats have a new method ``is_deprecated`` that
1143
implementations can override to return True to trigger a deprecation
1144
warning. (Jelmer Vernooij)
1146
* The ``revision_id`` parameter of
1147
``Repository.search_missing_revision_ids`` and
1148
``InterRepository.search_missing_revision_ids`` is deprecated. It is
1149
replaced by the ``revision_ids`` parameter. (Andrew Bennetts)
1151
* Working tree formats should now be registered on the format registry
1152
(``bzrlib.working_tree.format_registry``) rather than using the class
1153
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)
1155
* Exporting may now be done with a generator
1156
(``bzrlib.export.get_export_generator``) (Geoff/xaav, #791005)
1161
* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
1162
out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
1163
outside of tests. This class makes it easier to track exceptions in threads
1164
by catching them so they can be re-raised in the controlling thread. It's
1165
available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)
1167
* Correctly propagate malloc failures from diff-delta.c code as MemoryError
1168
so OOM conditions during groupcompress are clearly reported. This entailed a
1169
change to several function signatures. (Martin [gz], #633336)
1171
* ``HookPoint.lazy_hook`` and ``Hooks.install_named_lazy_hook`` can install
1172
hooks for which the callable is loaded lazily. (Jelmer Vernooij)
1177
* The Range parsing for HTTP requests will correctly parse incomplete ranges.
