94
* ``config.LocationMatcher`` properly excludes unrelated sections.
95
(Vincent Ladeuil, #829237)
97
* ``dirstate.fdatasync`` and ``repository.fdatasync`` can now properly be
98
disabled. (Vincent Ladeuil, #824513)
100
* Disable ``os.fsync`` and ``os.fdatasync`` by default when running
101
``bzr selftest``. You can use ``--sync`` to re-enable them.
102
(John Arbash Meinel, #837293)

136
* The test suite should now be able to run under weird environments where
137
``/etc/passwd`` doesn't contain the ``uid`` for the user running selftest
138
or where ``fakeroot`` is used but ``/root`` is inacessible.

This release marks the start of a new long-term-stable series. From here, we
147
will only make bugfix releases on the 2.4 series (2.4.1, etc, and support it
148
until February 2013), while 2.5 will become our new development series.
150
This is a bugfix and polish release over the 2.3 series, with a large number
151
of bugs fixed (>150 for the 2.4 series alone), and some performance
152
improvements. Support for python 2.4 and 2.5 has been dropped, many large
153
working tree operations have been optimized as well as some stacked branches
156
Only bugfixes from other stables series have been included since 2.4b5 so
157
all known fixed bugs are included here.
159
Users are encouraged to upgrade from the other stable series.

184
* A call to CHKInventory's filter-method will not result in a
185
DuplicateFileId error, if you move a subfolder and change a file in
187
(Bastian Bowe, #809901)
189
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
190
checks to see if the most recent published source package version for
191
that project is present in the branch tags. This should help developers
192
trust whether the packaging branch is up-to-date and can be used for new
193
changes. The level of verbosity is controlled by the config item
194
``launchpad.packaging_verbosity``. It can be set to one of
201
only display if the branch is out-of-date
204
also display single-line up-to-date and missing,
208
(default) display multi-line content for all states
211
(John Arbash Meinel, #609187, #812928)
213
* Cope with not all Python versions having a ``clear`` method on
214
``TestCase._type_equality_funcs``.
215
(Martin [gz], Jelmer Vernooij, #809048)
217
* Fetching tags when fetching the tip revision of a branch is now
218
controlled by the config setting ``branch.fetch_tags``. The behavior has
219
been reverted to 2.3's not-fetching tagged revisions by default.
220
(John Arbash Meinel, #771184)
222
* The fix for bug #513709 caused us to open a new connection when
223
switching a lightweight checkout that was pointing at a bound branch.
224
This isn't necessary because we know the master URL without opening it,
225
avoiding an extra SSH connection, etc.
226

232
.. Improved or updated documentation.
237
.. Changes that may require updates in plugins or other code that uses

.. Fixes and changes that are only relevant to bzr's test framework and
250
suite. This can include new facilities for writing tests, fixes to
251
spurious test failures and changes to the way things should be tested.
253
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
254
cleanly and reliably allows tests using `BranchBuilder` to construct
255
branches that e.g. rename files out of a directory and unversion that
256
directory in the same revision. Previously some changes were impossible
257
due to the order that `build_snapshot` performs its actions.
260
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
261
just compares the bytes in the dirstate file to its pristine state,
262
rather than opening the WorkingTree and calling ``last_revision()``.
263
This reduces the overall test suite time by about 10% on my laptop.
272
This is the fifth (and last) beta of the 2.4 series leading to
273
2.4.0 release in August 2011. Beta releases are suitable for
274
everyday use but may cause some incompatibilities with plugins.
276
This release includes all bug fixed in previous series known at
277
the time of this release.

*****************************
287
* New command ``verify-signatures`` to check if all commits or specified commits
288
have digital signatures from trusted keys. Requires python-gpgme to be
291
* New option ``--signatures`` for ``bzr log`` to display digital signature
292
verification results for each commit.
294
* Config option acceptable_keys to list which GPG keys are verified as trusted.
296
* Config option validate_signatures_in_log to always show signatures in
302
* ``Branch.open`` is now about 3x faster (about 2ms instead of 6.5ms).
305
* Pack, dirstate, and index files are synced to persistent storage if
306
possible when writing finishes, to reduce the risk of problems caused by
307
a machine crash or similar problem. This can be turned off through the
308
``dirstate.fdatasync`` and ``repository.fdatasync`` options, which can
309
be set in ``locations.conf`` or ``bazaar.conf``. (Martin Pool,
315
* Display a proper error message when a config file content cannot be
316
decoded as UTF-8 or when it cannot be parsed.
317
(Vincent Ladeuil, #502060, #688677, #797246)
319
* Generate a single conflict (instead of two) when merging a branch
320
modifying and renaming a file in a branch that deleted it (or vice-versa).
321
(Vincent Ladeuil, #688101)
323
* Give a more helpful message when the bzr executable doesn't match the
324
library. (This typically happens because of a misconfigured PYTHONPATH
325
or half-installed bzr.)
326
(Martin Pool, #804553)
328
* Properly load utf8-encoded config files. (Vincent Ladeuil, #799212)
330
* ``GraphThunkIdsToKeys.merge_sort`` now properly returns
331
keys rather than ids. (Jelmer Vernooij, #799677)
333
* ``TreeTransformBase.fixup_new_roots`` can now check that a tree root
334
is present. (Jelmer Vernooij, #801257)
339
* New attributes ``WorkingTreeFormat.supports_versioned_directories`` and
340
``RepositoryFormat.supports_versioned_directories``.
341
(Jelmer Vernooij, #765815)
343
* The "revno" field type when using the python version-info format is now
344
a string (to handle dotted revnos) (Benoît Pierre, #796259)
349
* Start implementing localization, starting with command help text (but not
350
the command options themselves). This will allow bootstrapping the bzr
351
internationalization process. (Inada Naoki)
356
* Fix test failures when running as a homeless user (debian buildd). Tests
357
leaking into ``${HOME}/.bzr.log`` should be detected properly now.

376
.. These may require users to change the way they use Bazaar.
378
* Do not treat configuration option 'check_signatures = require' as if
379
it were 'create_signatures = always' (Jonathan Riddell)
384
.. New commands, options, etc that users may wish to try out.
386
* Hooks have been added for config stacks: ``get``, ``set`` and ``remove``
387
are called when an option is respectively read, modified or deleted. Also
388
added ``load`` and ``save`` hooks for config stores, called when the
389
stores are loaded or saved. (Vincent Ladeuil)
391
* New hook server_exception in bzrlib.smart.server to catch any
392
exception caused while running bzr serve.
393
(Jonathan Riddell, #274578)
395
* New hook set_commit_message in bzrlib.msgeditor to set a commit message
396
and revision properties. (Jonathan Riddell, #274578)
398
* Support ``-S`` as an alias for ``--short`` for the ``log`` and
399
``missing`` commands. (Martin von Gagern, #38655)
404
.. Improvements to existing commands, especially improved performance
405
or memory usage, or better results.
407
* ``bzr annotate`` can be run without setting whoami data first.
408
(Jonathan Riddell, #667408)
413
.. Fixes for situations where bzr would previously crash or give incorrect
414
or undesirable results.
416
* Bazaar can now detect when a lock file is held by a dead process
417
originating from the same machine, and steal the lock after printing a
418
message to the user. This is off by default, for safety, but can be
419
turned on by setting the configuration variable ``locks.steal_dead`` to
421
(Martin Pool, #220464)
423
* ``bzr version-info`` now works when the tree is on a dotted revno.
424
(Benoît Pierre, #796259)
426
* Credentials in the log output produced by ``-Dhttp`` are masked so users
427
can more freely post them in bug reports. (Vincent Ladeuil, #723074)
429
* Fix a race condition for ``server_started`` hooks leading to a spurious
430
test failure. (Vincent Ladeuil, #789167)
432
* Fix exporting subdirectory with ``--per-file-timestamps``.
433
(Szilveszter Farkas, #795557)
435
* Handle files that get created but don't get used during TreeTransform.
436
``open()`` can create a file, and still raise an exception before it
437
returns. So anything we might have created, make sure we destroy during
438
``finalize()``. (Martin [gz], #597686)
440
* ``pack_repo`` now uses ``Transport.move`` instead of
441
``Transport.rename``, deleting any existing targets even on SFTP.
442
(Martin von Gagern, #421776)
444
* Pass the ``build_mo`` command to the rest of the setup() calls in
445
setup.py. The ``bdist_wininst`` and ``py2exe`` code paths were failing
446
because ``build_mo`` became a required step that they didn't know about.
447
(John Arbash Meinel, #787122)
449
* Preserve existing ``root-id`` when merging an unrelated branch.
450
(Aaron Bentley, #806356)
452
* Properly avoid re-adding a file after it changes case on CICP
453
filesystems. (John Arbash Meinel, #798130)
455
* Reports the original error when an InvalidHttpResponse exception is
456
encountered to facilitate debug. (Vincent Ladeuil, #788530)
458
* Reports a non-existent file error when trying to merge in a file
459
that does not exist. (Jonathan Riddell, #330063)
461
* ``UIFactory.prompt``, ``UIFactory.get_username``,
462
``UIFactory.get_password`` and ``UIFactory.get_boolean`` now require a
463
unicode prompt to be passed in. (Jelmer Vernooij, #592083)
465
* Support merging into the empty tree. (Aaron Bentley, #595328)
470
.. Improved or updated documentation.
472
* Improve documentation of ``bzr merge --force``.
473
(Neil Martinsen-Burrell, #767307)
475
* Make docs for configuration options for digital signatures match
476
reality. (Jonathan Riddell)
478
* Add user-guide page on GPG signatures. (Jonathan Riddell)
483
.. Changes that may require updates in plugins or other code that uses
486
* Checking for a file id in a `Tree` or `Inventory` using ``in`` is now
487
deprecated. Instead, use `has_id`.
490
* Exporters are now all exposed as generators, rather than as single-call
491
functions, so that calling code can take stream the output.
494
* Information about held lockdir locks returned from eg `LockDir.peek` is
495
now represented as a `LockHeldInfo` object, rather than a plain
499
* Remove `file_status` function.
502
* ``Repository.iter_reverse_revision_history`` is now deprecated.
503
Use ``Graph.iter_lefthand_ancestry`` instead.
504
(Jelmer Vernooij, #739481)
506
* ``Repository.get_ancestry`` has been deprecated. Use
507
``Graph.iter_ancestry`` instead.
508
(Jelmer Vernooij, #784511)
513
.. Major internal changes, unlikely to be visible to users or plugin
514
developers, but interesting for bzr developers.
516
* ``tools/check-newsbugs.py`` accepts a ``--browser`` option to open
517
corresponding launchpad pages in a browser. (Vincent Ladeuil)
522
.. Fixes and changes that are only relevant to bzr's test framework and
523
suite. This can include new facilities for writing tests, fixes to
524
spurious test failures and changes to the way things should be tested.
526
* A `ImportTariffTestCase` base class has been added in
527
``bzrlib.tests.test_import_tariff``, which can be used for import tariff
528
tests in plugins. (Jelmer Vernooij, #793465)
530
* Fix deadlock in `TestImportTariffs.test_simple_serve` when stderr gets
531
more output than fits in the default buffer. This was happening on the
532
Windows buildslave, and could easily happen in other circumstances where
533
the default OS buffer size for pipes is small or the ``python -v``
534
output is large. (Andrew Bennetts, #784802)
536
* Fix spurious test failure on OSX for WorkingTreeFormat2.
537
(Vincent Ladeuil, #787942)
539
* Re-target ``bb.test_merge.TestMerge.test_merge_reversed_revision_range``
540
and rewrite it as a parametrized test to avoid unrelated failures.
541
(Vincent Ladeuil, #795456)
543
* Show log file contents from subprocesses started by
544
`start_bzr_subprocess` in test failure details. This may help diagnose
545
strange hangs and failures involving subprocesses. (Andrew Bennetts)
547
* Skip ``utextwrap`` tests when ``sphinx`` breaks text_wrap by an hostile
548
monkey-patch to textwrap.TextWrapper.wordsep_re.
549
(Vincent Ladeuil, #785098)
551
* Multiple ``selftest --exclude`` options are now combined instead of
552
overriding each other. (Vincent Ladeuil, #746991)
554
* Restore some ``FTPTransport`` test coverage by allowing ``pyftpdlib
555
0.6.0`` to be used. Also restore ``medusa`` support while leaving it
556
disabled to make it easier to use if/when we can in the future.
557
(Vincent Ladeuil, #781140)
559
* `TestImportTariffs` no longer uses the real ``$HOME``. This prevents it
560
from polluting ``$HOME/.bzr.log`` or being accidentally influenced by
561
user configuration such as aliases. It still runs with all the user's
562
plugins enabled, as intended.
563

*****************************
582
.. These may require users to change the way they use Bazaar.
584
* ``bzr-2.4`` has officially dropped support for python2.4 and python2.5.
585
We will continue to maintain ``bzr-2.3`` for people who still need to
586
use those versions of python. (John Arbash Meinel)
591
.. New commands, options, etc that users may wish to try out.
593
* The text compressor used for 2a repositories now has a tweakable
594
parameter that can be set in bazaar.conf.
595
``bzr.groupcompress.max_entries_per_source`` default of 65536.
596
When doing compression, we build up an index of locations to match
597
against. Setting this higher will result in slightly better compression,
598
at a cost of more memory. Note that a value of 65k represents fully
599
sampling a 1MB file. So this only has an effect when compressing texts
600
larger than N*16 bytes. (John Arbash Meinel, #602614)
605
.. Improvements to existing commands, especially improved performance
606
or memory usage, or better results.
608
* ``bzr branch --stacked`` from a smart server uses the network a little
609
more efficiently. For a simple branch it reduces the number of
610
round-trips by about 20%. (Andrew Bennetts)
612
* ``bzr log --line`` scales the width of the author field with the size of
613
the line. This means that the full author name is shown when the
614
environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)
616
* ``bzr pull`` now properly triggers the fast
617
``CHKInventory.iter_changes`` rather than the slow generic
618
inter-Inventory changes. It used to use a ``DirStateRevisionTree`` as
619
one of the source trees, which is faster when we have to read the whole
620
inventory anyway, but much slower when we can get just the delta out of
621
the repository. On a 70k record tree, this changes ``bzr pull`` from 28s
622
down to 17s. (John Arbash Meinel, #780677)
624
* Slightly reduced memory consumption when fetching into a 2a repository
625
by reusing existing caching a little better. (Andrew Bennetts)
627
* Speed up ``bzr status`` by a little bit when there are a couple of
628
modified files. We now track how many files we have seen that need
629
updating, and only rewrite the dirstate file if enough of them have
630
changed. The default is 10, and can be overridden by setting the branch
631
option "``bzr.workingtree.worth_saving_limit``".
632
(Ian Clatworthy, John Arbash Meinel, #380202)
634
* Speed up ``bzr uncommit``. Instead of resetting the dirstate from
635
scratch, use ``update_basis_by_delta``, computing the delta from the
636
repository. (John Arbash Meinel, #780544)
641
.. Fixes for situations where bzr would previously crash or give incorrect
642
or undesirable results.
644
* All Tree types can now be exported as tar.*, zip or directories.
647
* ``bzr merge --no-remember location`` never sets ``submit_branch``.
648
(Vincent Ladeuil, #782169)
650
* ``bzr pull --no-remember location`` never sets
651
``parent_location``. ``bzr push --no-remember location`` never
652
sets ``push_location``. ``bzr send --no-remember
653
submit_location public_location`` never sets ``submit_branch``
654
nor ``public_branch``. (Vincent Ladeuil)
656
* Conflicts involving non-ascii filenames are now properly reported rather
657
than failing with a UnicodeEncodeError. (Martin [GZ], #686161)
659
* Correct parent is now set when using 'switch -b' with bound branches.
660
(A. S. Budden, #513709)
662
* Fix `bzr plugins` regression in bzr 2.4 which resulted in a traceback
663
from writelines on ckj terminals. (Martin [GZ], #754082)
665
* ``WT.inventory`` and ``WT.iter_entries_by_dir()`` was not correctly
666
reporting subdirectories that were tree references (in formats that
667
supported them). (John Arbash Meinel, #764677)
669
* Merging into empty branches now gives an error as this is currently
670
not supported. (Jonathan Riddell, #242175)
672
* Do not show exception to user on pointless commit error.
673
(Jonathan Riddell #317357)
675
* ``WT.update_basis_by_delta`` no longer requires that the deltas match
676
the current WT state. This allows ``update_basis_by_delta`` to be used
677
by more commands than just commit. Updating with a delta allows us to
678
not load the whole inventory, which can take 10+s with large trees.
679
(Jonathan Riddell, John Arbash Meinel, #781168)
681
* ``bzr mv --after old_name new_name`` now works if "new_name" is newly
682
added. (Benoît Pierre)
688
.. Improved or updated documentation.
690
* Restore the workaround for option names including dots (--1.14) which was
691
disabled when we stopped listing --1.9 as a format.
692
(Vincent Ladeuil, #782289)
697
.. Changes that may require updates in plugins or other code that uses
700
* ``annotate_file`` has been deprecated in favor of
701
``annotate_file_revision_tree``. (Jelmer Vernooij, #775598)
703
* ``Branch.fetch`` now takes an optional ``limit`` argument.
704
(Andrew Bennetts, Jelmer Vernooij, #750175)
706
* ``Inter.get`` now raises ``NoCompatibleInter`` if there are no
707
compatible optimisers rather than an instance of the class it is called
708
on. (Jelmer Vernooij)
710
* ``Branch.push`` now takes a ``lossy`` argument.
711
``Branch.lossy_push`` has been removed.
714
* New method ``Repository.get_file_graph`` which can return the
715
per-file revision graph. (Jelmer Vernooij, #775578)
717
* The default implementation of ``Branch`` is now oriented to
718
storing the branch tip. Branch implementations which store the full
719
history should now subclass ``FullHistoryBzrBranch``.
720
``Branch._last_revision_info`` has been renamed to
721
``Branch._read_last_revision_info`` (Jelmer Vernooij)
723
* ``Tree.__iter__`` has been deprecated; use ``Tree.all_file_ids``
724
instead. (Jelmer Vernooij)
726
* ``Tree.get_symlink_target`` now takes an optional ``path``
727
argument. (Jelmer Vernooij)
732
.. Major internal changes, unlikely to be visible to users or plugin
733
developers, but interesting for bzr developers.
735
* ``MutableTree.smart_add`` now uses inventory deltas.
736
(Jelmer Vernooij, #146165)
738
* Removed ``bzrlib.branch._run_with_write_locked_target`` as
739
``bzrlib.cleanup`` provides the same functionality in a more general
740
way. (Andrew Bennetts)
745
.. Fixes and changes that are only relevant to bzr's test framework and
746
suite. This can include new facilities for writing tests, fixes to
747
spurious test failures and changes to the way things should be tested.
749
* A test that was expected to fail but passes instead now counts as a failure
750
catching up with new testtools and subunit handling. (Martin [GZ], #654474)
752
* Make it easier for plugins to reuse the per_workingtree scenarios by
753
restoring the wt_scenarios helper that was accidentally deleted.
754
(Vincent Ladeuil, #783472)
756
* Removed ``test_breakin`` tests that were excessively prone to hanging,
757
did not work on Wine, and partly already disabled.
758
(Martin Pool, #408814, #746985)
760
* Windows locations are different and should be tested accordingly.
761
(Vincent Ladeuil, #788131)
768
This is the second beta of the 2.4 series, leading to a 2.4.0 release in
769
August 2011. Beta releases are suitable for everyday use but may cause some
770
incompatibilities with plugins.
772
This release includes all bug fixed in previous series known at the time of
776
External Compatibility Breaks
777
*****************************
779
.. These may require users to change the way they use Bazaar.
781
* Two command synonyms for ``bzr branch`` have been deprecated, to avoid
782
confusion and to allow the names to later be reused. The removed names
783
are: ``get`` and ``clone``. (Martin Pool, #506265)
788
.. New commands, options, etc that users may wish to try out.
790
* ``bzr commit`` now supports a ``--lossy`` argument that can be used
791
to discard any data that can not be natively represented when committing
792
to a foreign VCS. (Jelmer Vernooij, #587721)
797
.. Improvements to existing commands, especially improved performance
798
or memory usage, or better results.
800
* ``bzr merge`` in large trees is now significantly faster. On a 70k entry
801
tree, the time went from ~3min down to 30s. This also effects ``bzr pull``
802
and ``bzr update`` since they use the same merge logic to update the
803
WorkingTree. (John Arbash Meinel, #759091)
805
* ``bzr revert`` now properly uses ``bzr status``'s optimized
806
``iter_changes``. This can be a significant performance difference (33s
807
to 5s on large trees). (John Arbash Meinel, #759096)
809
* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
810
the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
811
being handed off to the remote server anyway (xmlrpc has been mapping
812
``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
813
than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
814
months now.) By doing it ourselves, we can cut out substantial startup
815
time. From Netherlands to London it was taking 368ms to do the XMLRPC
816
call as much as 2s from Sydney. You can test the local logic by using
817
``-Dlaunchpad``. (John Arbash Meinel, #397739)
819
* When building a new WorkingTree (such as during ``bzr co`` or
820
``bzr branch``) we now properly store the stat and hash of files that
821
are old enough. This saves a fair amount of time on the first
822
``bzr status`` (on a 500MB tree, it saves about 30+s).
823
(John Arbash Meinel, #740932)
829
.. Fixes for situations where bzr would previously crash or give incorrect
830
or undesirable results.
832
* Arguments that can't be decoded to unicode in the current posix locale give
833
a clearer error message without a traceback. (Martin [gz], #745712)
835
* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
836
mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
837
these default values aren't relied on very often so this probably
838
wasn't causing any trouble. (Andrew Bennetts)
840
* ``bzr log`` now works on revisions which are not in the current branch.
841
(Matt Giuca, #241998)
843
* Don't rewrite the dirstate file when non-interesting changes have
844
occurred. This can significantly improve 'bzr status' times when there
845
are only small changes to a large tree.
846
(Ian Clatworthy, John Arbash Meinel, #380202)
848
* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
850
* ``bzrlib.merge.Merge`` now calls ``iter_changes`` without
851
``include_unversioned=True``. This makes it significantly faster in many
852
cases, because it only looks at modified files, rather than building
853
information about all files. This can cause failures in other
854
TreeTransform code, because it had been expecting to know the names of
855
things which had not changed (such as parent directories). All cases we
856
know about so far have been fixed, but there may be fallout for edge
857
cases that we are missing. (John Arbash Meinel, #759091)
859
* ``SFTPTransport`` is more pro-active about closing file-handles. This
860
reduces the chance of having threads fail from async requests while
861
running the test suite. (John Arbash Meinel, #656170)
863
* Standalone bzr.exe installation on Windows: user can put additional python
864
libraries into ``site-packages`` subdirectory of the installation directory,
865
this might be required for "installing" extra dependencies for some plugins.
866
(Alexander Belchenko, #743256)
868
* ``transform.revert()`` has been updated to use
869
``wt.iter_changes(basis_tree)`` rather than
870
``basis_tree.iter_changes(wt)``. This allows the optimized code path to
871
kick in, improving ``bzr revert`` times significantly (33s to 4s on
872
large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)
874
* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
875
parameter. If supplied, when the transform is applied, it will then call
876
``self._tree._observed_sha1`` for those files. This lets us update the
877
hash-cache for content that we create, preventing us from re-reading the
878
content in the next ``bzr status``. (John Arbash Meinel, #740932)
883
* Added a section about using a shared SSH account on a server for bzr+ssh
884
access. (Russell Smith)
886
* The documentation now recommends using SSH rather than SFTP in the
887
tutorials and the examples, because that will generally be much faster
888
and better in cases where it can be used. SFTP is still available and
889
mentioned as an alternative. (Martin Pool, #636712)
894
.. Changes that may require updates in plugins or other code that uses
897
* ``Branch.update_revisions`` has been made private and should no
898
longer be used by external users. Use ``Branch.pull`` or ``Branch.push``
899
instead. (Jelmer Vernooij, #771765)
901
* Commands now have an `invoked_as` attribute, showing the name under
902
which they were called before alias expansion.
905
* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
908
* If you call `bzrlib.initialize` but forget to enter the resulting object
909
as a context manager, bzrlib will now be initialized anyhow.
910
(Previously simple programs calling bzrlib might find the library was
911
mysteriously silent.)
914
* Inventory-specific functionality has been split out of ``Tree`` into
915
a new ``InventoryTree`` class. Tree instances no longer
916
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
918
* Inventory-specific functionality has been split out of ``RevisionTree``
919
into a new ``InventoryRevisionTree`` class. RevisionTree instances no
920
longer necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
922
* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)
924
* ``revision_graph_can_have_wrong_parents`` is now an attribute
925
on ``RepositoryFormat`` rather than a method on ``Repository``.
928
* ``Testament`` now takes a ``tree`` rather than an
929
``inventory``. (Jelmer Vernooij, #762608)
931
* ``TestCase.failUnlessExists`` and ``failIfExists`` are deprecated in
932
favour of ``assertPathExists`` and ``assertPathDoesNotExist``
936
* The ``revno`` parameter of ``log.LogRevision`` may now be None,
937
representing a revision which is not in the current branch.
938
(Matt Giuca, #241998)
940
* The various knit pack repository format classes have been moved
941
from ``bzrlib.repofmt.pack_repo`` to
942
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)
944
* ``RevisionTree`` now has a new method ``get_file_revision``.
947
* ``WorkingTree`` no longer provides an ``inventory``. Instead,
948
all inventory-related functionality is now on the subclass
949
``InventoryWorkingTree`` that all native Bazaar working tree
950
implementations derive from. (Jelmer Vernooij)
955
.. Major internal changes, unlikely to be visible to users or plugin
956
developers, but interesting for bzr developers.
958
* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
959
functions on Linux, but they are wrapped on Windows so that fstat
960
matches lstat results across all python versions.
963
* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
964
happened to be updated as a side-effect of commit, but if we start using
965
the function elsewhere we might as well do it directly.
971
.. Fixes and changes that are only relevant to bzr's test framework and
972
suite. This can include new facilities for writing tests, fixes to
973
spurious test failures and changes to the way things should be tested.
975
* Stop using `failIf`, `failUnless`, `failIfEqual`, etc, that give
976
`PendingDeprecationWarnings` on Python2.7.
977
(Martin Pool, #760435)
985
This is the first beta of the 2.4 series, leading up to a 2.4.0
986
release in August 2011. Beta releases are suitable for everyday use
987
but may cause some incompatibilities with plugins. Some plugins may need
988
small updates to work with 2.4b1.
990
External Compatibility Breaks
991
*****************************
998
* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
999
in GNU format. See ``bzr help changelog_merge`` for details.
1002
* Configuration options can now use references to other options in the same
1003
file by enclosing them with curly brackets (``{other_opt}``). This makes it
1004
possible to use, for example,
1005
``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
1006
using a loom. During the beta period, the default behaviour is to disable
1007
this feature. It can be activated by declaring ``bzr.config.expand = True``
1008
in ``bazaar.conf``. (Vincent Ladeuil)
1010
* External merge tools can now be configured in bazaar.conf. See
1011
``bzr help configuration`` for more information. (Gordon Tyler, #489915)
1013
* The ``lp:`` directory service now supports Launchpad's QA staging.
1014
(Jelmer Vernooij, #667483)
1019
* A new hidden command ``bzr repair-workingtree``. This is a way to force
1020
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
1021
workaround. (John Arbash Meinel)
1023
* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
1024
This allows formats from plugins (such as looms) to efficiently tell the
1025
client which revisions need to be fetched. (Andrew Bennetts)
1027
* Branching, merging and pulling a branch now copies revisions named in
1028
tags, not just the tag metadata. (Andrew Bennetts, #309682)
1030
* ``bzr cat-revision`` no longer requires a working tree.
1031
(Jelmer Vernooij, #704405)
1033
* ``bzr export --per-file-timestamps`` for .tar.gz files will now
1034
override the mtime for trees exported on Python 2.7 and later, which
1035
expose the 'mtime' field in gzip files. This makes the output of
1036
``bzr export --per-file-timestamps`` for a particular tree
1037
deterministic. (Jelmer Vernooij, #711226)
1039
* ``bzr export --format=zip`` can now export to standard output,
1040
like the other exporters can. (Jelmer Vernooij, #513752)
1042
* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
1043
(Jelmer Vernooij, #551714)
1045
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
1046
sped up dramatically for large trees. Iterating by dir is not the best
1047
way to load data from a CHK inventory, so it preloads all the items in
1048
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
1049
of CHK data, down to just 150MB.) This has noticeable affects for things
1050
like building checkouts, etc. (John Arbash Meinel, #737234)
1055
* A MemoryError thrown on the server during a remote operation will now be
1056
usefully reported, and other unexpected errors will include the class name.
1057
(Martin [gz], #722416)
1059
* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
1060
(Andrew King, #537442)
1062
* ``bzr export`` to zip files will now set a mode on directories.
1063
(Jelmer Vernooij, #207253)
1065
* ``bzr export`` to tgz files will only write out the basename of the
1066
tarfile to the gzip file. (Jelmer Vernooij, #102234)
1068
* ``bzr push --overwrite`` with an older revision specified will now correctly
1069
roll back the target branch. (Jelmer Vernooij, #386576)
1071
* ``bzr lp-propose`` can now propose merges against packaging branches on
1072
Launchpad without requiring the target branch to be specified.
1073
(Jelmer Vernooij, #704647)
1075
* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
1076
instead leave setting the reviewer up to Launchpad if it was not specified.
1077
(Jelmer Vernooij, #583772)
1079
* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
1080
(Jelmer Vernooij, #213185)
1082
* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
1083
paths, however they may still print junk if not on a UTF-8 terminal.
1084
(Martin [gz], #707954)
1086
* ``bzr reconfigure --unstacked`` now copies revisions (and their
1087
ancestors) named in tags into the unstacked repository, not just the
1088
ancestry of the branch's tip. (Andrew Bennetts, #401646)
1090
* ``bzr serve`` no longer crashes when a server_started hook is installed and
1091
IPv6 support is available on the system. (Jelmer Vernooij, #293697)
1093
* ``bzr status`` will not rewrite the dirstate file if it only has
1094
'trivial' changes. (Currently limited to dir updates and newly-added
1095
files changing state.) This saves a bit of time for regular operations.
1096
eg. ``bzr status`` in a 100k tree takes 1.4s to compute the status, but 1s
1097
to re-save the dirstate file. (John Arbash Meinel, #765881)
1099
* ``bzr tags`` will no longer choke on branches with ghost revisions in
1100
their mainline and tags on revisions not in the branch ancestry.
1101
(Jelmer Vernooij, #397556)
1103
* ``bzr whoami`` will now display an error if both a new identity and
1104
``--email`` were specified. (Jelmer Vernooij, #680449)
1106
* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
1107
(Vincent Ladeuil, #706835)
1109
* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
1111
(Martin Pool, #586341)
1113
* Plugins incompatible with the current version of bzr no longer produce a
1114
warning on every command invocation. Instead, a message is shown by
1115
``bzr plugins`` and in crash reports.
1116
(#704195, Martin Pool)
1118
* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
1119
preserves the identity of default parameter values.
1120
(Andrew Bennetts, #718569)
1122
* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
1123
containing no rows. (Eric Siegerman, #715508)
1125
* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
1126
without an explicit public location. (Max Bowsher)
1128
* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
1129
number of available processors. (Jelmer Vernooij, #693140)
1134
* Added ``Branch.heads_to_fetch`` method. Implementations of the Branch API
1135
must now inherit or implement this method. (Andrew Bennetts, #721328)
1137
* Added ``bzrlib.mergetools`` module with helper functions for working with
1138
the list of external merge tools. (Gordon Tyler, #489915)
1140
* All methods and arguments that were deprecated before 2.0
1141
have been removed. (Jelmer Vernooij)
1143
* Branch formats should now be registered on the format registry
1144
(``bzrlib.branch.format_registry``) rather than using the class
1145
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)
1147
* ``Branch.set_revision_history`` is now deprecated.
1150
* ``BranchFormat.supports_leaving_lock()`` and
1151
``RepositoryFormat.supports_leaving_lock`` flags have been added.
1154
* ``Branch.fetch`` implementations must now accept an optional
1155
``fetch_tags`` keyword argument. (Andrew Bennetts)
1157
* ``Branch.import_last_revision_info`` is deprecated. Use the
1158
``import_last_revision_info_and_tags`` method instead.
1161
* Because it was too specific to BzrDir implementations,
1162
``ControlDir.sprout`` no longer has a default implementation; it now
1163
raises ``NotImplementedError``. (Jelmer Vernooij, #717937)
1165
* ``bzrlib.deprecated_graph`` has been removed. ``bzrlib.graph``
1166
scales better tree and should be used instead.
1167
(Jelmer Vernooij, #733612)
1169
* ``ControlDirFormat.register_format`` has been removed. Instead,
1170
``Prober`` implementations should now implement a ``known_formats``
1171
method. (Jelmer Vernooij)
1173
* ControlDirFormats can now provide a ``check_status`` method and
1174
raise a custom exception or warning when an unsupported or deprecated
1175
format is being opened. (Jelmer Vernooij, #731311)
1177
* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
1178
Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
1179
``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
1180
instead. (Jelmer Vernooij, #721971)
1182
* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
1183
indicates whether the components of the bzrdir can be upgraded
1184
independent of the ``BzrDir``. (Jelmer Vernooij)
1186
* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
1187
now deprecated in favour of the ``BzrProber.formats`` format registry.
1190
* ``ControlDir`` implementations no longer have to provide the
1191
``get_branch_transport``, ``get_workingtree_transport`` and
1192
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)
1194
* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
1195
``bzrlib.controldir``. (Jelmer Vernooij)
1197
* Repository formats can now provide
1198
``_get_extra_interrepo_test_combinations`` in the same module
1199
to provide extra test combinations for ``bzrlib.tests.per_repository``.
1202
* Repository formats should now be registered on the format registry
1203
(``bzrlib.repository.format_registry``) rather than using the class
1204
methods on ``RepositoryFormat``. (Jelmer Vernooij)
1206
* Repository formats can now indicate they do not support the full
1207
VersionedFiles API by setting the ``supports_full_versioned_files``
1208
attribute to False. A subset of the VersionedFiles API
1209
(signatures and text graphs) still needs to be supported.
1212
* Repository formats have a new method ``is_deprecated`` that
1213
implementations can override to return True to trigger a deprecation
1214
warning. (Jelmer Vernooij)
1216
* The ``revision_id`` parameter of
1217
``Repository.search_missing_revision_ids`` and
1218
``InterRepository.search_missing_revision_ids`` is deprecated. It is
1219
replaced by the ``revision_ids`` parameter. (Andrew Bennetts)
1221
* Working tree formats should now be registered on the format registry
1222
(``bzrlib.working_tree.format_registry``) rather than using the class
1223
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)
1225
* Exporting may now be done with a generator
1226
(``bzrlib.export.get_export_generator``) (Geoff/xaav, #791005)
1231
* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
1232
out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
1233
outside of tests. This class makes it easier to track exceptions in threads
1234
by catching them so they can be re-raised in the controlling thread. It's
1235
available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)
1237
* Correctly propagate malloc failures from diff-delta.c code as MemoryError
1238
so OOM conditions during groupcompress are clearly reported. This entailed a
1239
change to several function signatures. (Martin [gz], #633336)
1241
* ``HookPoint.lazy_hook`` and ``Hooks.install_named_lazy_hook`` can install
1242
hooks for which the callable is loaded lazily. (Jelmer Vernooij)
1247
* The Range parsing for HTTP requests will correctly parse incomplete ranges.
