.. 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.
29
* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
30
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)
35
* Fixed loading of external merge tools from config to properly decode
36
command-lines which contain embedded quotes. (Gordon Tyler, #828803)
38
* Prevent several kinds of OverflowError and other fallout from failing to fit
39
stat fields into four bytes in dirstate pack_stat implementations.
40
(Martin Packman, #683191 #706957)
45
.. Improved or updated documentation.

57
developers, but interesting for bzr developers.
62
.. Fixes and changes that are only relevant to bzr's test framework and
63
suite. This can include new facilities for writing tests, fixes to
64
spurious test failures and changes to the way things should be tested.

101
* ``config.LocationMatcher`` properly excludes unrelated sections.
102
(Vincent Ladeuil, #829237)
104
* ``dirstate.fdatasync`` and ``repository.fdatasync`` can now properly be
105
disabled. (Vincent Ladeuil, #824513)
107
* Disable ``os.fsync`` and ``os.fdatasync`` by default when running
108
``bzr selftest``. You can use ``--sync`` to re-enable them.
109
(John Arbash Meinel, #837293)
111
* Fix i18n use when no environment variables are set. (Jelmer Vernooij, #810701)
113

143
* The test suite should now be able to run under weird environments where
144
``/etc/passwd`` doesn't contain the ``uid`` for the user running selftest
145
or where ``fakeroot`` is used but ``/root`` is inacessible.

153
This release marks the start of a new long-term-stable series. From here, we
154
will only make bugfix releases on the 2.4 series (2.4.1, etc, and support it
155
until February 2013), while 2.5 will become our new development series.
157
This is a bugfix and polish release over the 2.3 series, with a large number
158
of bugs fixed (>150 for the 2.4 series alone), and some performance
159
improvements. Support for python 2.4 and 2.5 has been dropped, many large
160
working tree operations have been optimized as well as some stacked branches
163
Only bugfixes from other stables series have been included since 2.4b5 so
164
all known fixed bugs are included here.
166
Users are encouraged to upgrade from the other stable series.

191
* A call to CHKInventory's filter-method will not result in a
192
DuplicateFileId error, if you move a subfolder and change a file in
194
(Bastian Bowe, #809901)
196
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
197
checks to see if the most recent published source package version for
198
that project is present in the branch tags. This should help developers
199
trust whether the packaging branch is up-to-date and can be used for new
200
changes. The level of verbosity is controlled by the config item
201
``launchpad.packaging_verbosity``. It can be set to one of
208
only display if the branch is out-of-date
211
also display single-line up-to-date and missing,
215
(default) display multi-line content for all states
218
(John Arbash Meinel, #609187, #812928)
220
* Cope with not all Python versions having a ``clear`` method on
221
``TestCase._type_equality_funcs``.
222
(Martin [gz], Jelmer Vernooij, #809048)
224
* Fetching tags when fetching the tip revision of a branch is now
225
controlled by the config setting ``branch.fetch_tags``. The behavior has
226
been reverted to 2.3's not-fetching tagged revisions by default.
227
(John Arbash Meinel, #771184)
229
* The fix for bug #513709 caused us to open a new connection when
230
switching a lightweight checkout that was pointing at a bound branch.
231
This isn't necessary because we know the master URL without opening it,
232
avoiding an extra SSH connection, etc.
233
(John Arbash Meinel, #812285)
239
.. Improved or updated documentation.

.. Fixes and changes that are only relevant to bzr's test framework and
257
suite. This can include new facilities for writing tests, fixes to
258
spurious test failures and changes to the way things should be tested.
260
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
261
cleanly and reliably allows tests using `BranchBuilder` to construct
262
branches that e.g. rename files out of a directory and unversion that
263
directory in the same revision. Previously some changes were impossible
264
due to the order that `build_snapshot` performs its actions.
267
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
268
just compares the bytes in the dirstate file to its pristine state,
269
rather than opening the WorkingTree and calling ``last_revision()``.
270
This reduces the overall test suite time by about 10% on my laptop.
279
This is the fifth (and last) beta of the 2.4 series leading to
280
2.4.0 release in August 2011. Beta releases are suitable for
281
everyday use but may cause some incompatibilities with plugins.
283
This release includes all bug fixed in previous series known at
284
the time of this release.

*****************************
294
* New command ``verify-signatures`` to check if all commits or specified commits
295
have digital signatures from trusted keys. Requires python-gpgme to be
298
* New option ``--signatures`` for ``bzr log`` to display digital signature
299
verification results for each commit.
301
* Config option acceptable_keys to list which GPG keys are verified as trusted.
303
* Config option validate_signatures_in_log to always show signatures in
309
* ``Branch.open`` is now about 3x faster (about 2ms instead of 6.5ms).
312
* Pack, dirstate, and index files are synced to persistent storage if
313
possible when writing finishes, to reduce the risk of problems caused by
314
a machine crash or similar problem. This can be turned off through the
315
``dirstate.fdatasync`` and ``repository.fdatasync`` options, which can
316
be set in ``locations.conf`` or ``bazaar.conf``. (Martin Pool,
322
* Display a proper error message when a config file content cannot be
323
decoded as UTF-8 or when it cannot be parsed.
324
(Vincent Ladeuil, #502060, #688677, #797246)
326
* Generate a single conflict (instead of two) when merging a branch
327
modifying and renaming a file in a branch that deleted it (or vice-versa).
328
(Vincent Ladeuil, #688101)
330
* Give a more helpful message when the bzr executable doesn't match the
331
library. (This typically happens because of a misconfigured PYTHONPATH
332
or half-installed bzr.)
333
(Martin Pool, #804553)
335
* Properly load utf8-encoded config files. (Vincent Ladeuil, #799212)
337
* ``GraphThunkIdsToKeys.merge_sort`` now properly returns
338
keys rather than ids. (Jelmer Vernooij, #799677)
340
* ``TreeTransformBase.fixup_new_roots`` can now check that a tree root
341
is present. (Jelmer Vernooij, #801257)
346
* New attributes ``WorkingTreeFormat.supports_versioned_directories`` and
347
``RepositoryFormat.supports_versioned_directories``.
348
(Jelmer Vernooij, #765815)
350
* The "revno" field type when using the python version-info format is now
351
a string (to handle dotted revnos) (Benoît Pierre, #796259)
356
* Start implementing localization, starting with command help text (but not
357
the command options themselves). This will allow bootstrapping the bzr
358
internationalization process. (Inada Naoki)
363
* Fix test failures when running as a homeless user (debian buildd). Tests
364
leaking into ``${HOME}/.bzr.log`` should be detected properly now.

*****************************
383
.. These may require users to change the way they use Bazaar.
385
* Do not treat configuration option 'check_signatures = require' as if
386
it were 'create_signatures = always' (Jonathan Riddell)
391
.. New commands, options, etc that users may wish to try out.
393
* Hooks have been added for config stacks: ``get``, ``set`` and ``remove``
394
are called when an option is respectively read, modified or deleted. Also
395
added ``load`` and ``save`` hooks for config stores, called when the
396
stores are loaded or saved. (Vincent Ladeuil)
398
* New hook server_exception in bzrlib.smart.server to catch any
399
exception caused while running bzr serve.
400
(Jonathan Riddell, #274578)
402
* New hook set_commit_message in bzrlib.msgeditor to set a commit message
403
and revision properties. (Jonathan Riddell, #274578)
405
* Support ``-S`` as an alias for ``--short`` for the ``log`` and
406
``missing`` commands. (Martin von Gagern, #38655)
411
.. Improvements to existing commands, especially improved performance
412
or memory usage, or better results.
414
* ``bzr annotate`` can be run without setting whoami data first.
415
(Jonathan Riddell, #667408)
420
.. Fixes for situations where bzr would previously crash or give incorrect
421
or undesirable results.
423
* Bazaar can now detect when a lock file is held by a dead process
424
originating from the same machine, and steal the lock after printing a
425
message to the user. This is off by default, for safety, but can be
426
turned on by setting the configuration variable ``locks.steal_dead`` to
428
(Martin Pool, #220464)
430
* ``bzr version-info`` now works when the tree is on a dotted revno.
431
(Benoît Pierre, #796259)
433
* Credentials in the log output produced by ``-Dhttp`` are masked so users
434
can more freely post them in bug reports. (Vincent Ladeuil, #723074)
436
* Fix a race condition for ``server_started`` hooks leading to a spurious
437
test failure. (Vincent Ladeuil, #789167)
439
* Fix exporting subdirectory with ``--per-file-timestamps``.
440
(Szilveszter Farkas, #795557)
442
* Handle files that get created but don't get used during TreeTransform.
443
``open()`` can create a file, and still raise an exception before it
444
returns. So anything we might have created, make sure we destroy during
445
``finalize()``. (Martin [gz], #597686)
447
* ``pack_repo`` now uses ``Transport.move`` instead of
448
``Transport.rename``, deleting any existing targets even on SFTP.
449
(Martin von Gagern, #421776)
451
* Pass the ``build_mo`` command to the rest of the setup() calls in
452
setup.py. The ``bdist_wininst`` and ``py2exe`` code paths were failing
453
because ``build_mo`` became a required step that they didn't know about.
454
(John Arbash Meinel, #787122)
456
* Preserve existing ``root-id`` when merging an unrelated branch.
457
(Aaron Bentley, #806356)
459
* Properly avoid re-adding a file after it changes case on CICP
460
filesystems. (John Arbash Meinel, #798130)
462
* Reports the original error when an InvalidHttpResponse exception is
463
encountered to facilitate debug. (Vincent Ladeuil, #788530)
465
* Reports a non-existent file error when trying to merge in a file
466
that does not exist. (Jonathan Riddell, #330063)
468
* ``UIFactory.prompt``, ``UIFactory.get_username``,
469
``UIFactory.get_password`` and ``UIFactory.get_boolean`` now require a
470
unicode prompt to be passed in. (Jelmer Vernooij, #592083)
472
* Support merging into the empty tree. (Aaron Bentley, #595328)
477
.. Improved or updated documentation.
479
* Improve documentation of ``bzr merge --force``.
480
(Neil Martinsen-Burrell, #767307)
482
* Make docs for configuration options for digital signatures match
483
reality. (Jonathan Riddell)
485
* Add user-guide page on GPG signatures. (Jonathan Riddell)
490
.. Changes that may require updates in plugins or other code that uses
493
* Checking for a file id in a `Tree` or `Inventory` using ``in`` is now
494
deprecated. Instead, use `has_id`.
497
* Exporters are now all exposed as generators, rather than as single-call
498
functions, so that calling code can take stream the output.
501
* Information about held lockdir locks returned from eg `LockDir.peek` is
502
now represented as a `LockHeldInfo` object, rather than a plain
506
* Remove `file_status` function.
509
* ``Repository.iter_reverse_revision_history`` is now deprecated.
510
Use ``Graph.iter_lefthand_ancestry`` instead.
511
(Jelmer Vernooij, #739481)
513
* ``Repository.get_ancestry`` has been deprecated. Use
514
``Graph.iter_ancestry`` instead.
515
(Jelmer Vernooij, #784511)
520
.. Major internal changes, unlikely to be visible to users or plugin
521
developers, but interesting for bzr developers.
523
* ``tools/check-newsbugs.py`` accepts a ``--browser`` option to open
524
corresponding launchpad pages in a browser. (Vincent Ladeuil)
529
.. Fixes and changes that are only relevant to bzr's test framework and
530
suite. This can include new facilities for writing tests, fixes to
531
spurious test failures and changes to the way things should be tested.
533
* A `ImportTariffTestCase` base class has been added in
534
``bzrlib.tests.test_import_tariff``, which can be used for import tariff
535
tests in plugins. (Jelmer Vernooij, #793465)
537
* Fix deadlock in `TestImportTariffs.test_simple_serve` when stderr gets
538
more output than fits in the default buffer. This was happening on the
539
Windows buildslave, and could easily happen in other circumstances where
540
the default OS buffer size for pipes is small or the ``python -v``
541
output is large. (Andrew Bennetts, #784802)
543
* Fix spurious test failure on OSX for WorkingTreeFormat2.
544
(Vincent Ladeuil, #787942)
546
* Re-target ``bb.test_merge.TestMerge.test_merge_reversed_revision_range``
547
and rewrite it as a parametrized test to avoid unrelated failures.
548
(Vincent Ladeuil, #795456)
550
* Show log file contents from subprocesses started by
551
`start_bzr_subprocess` in test failure details. This may help diagnose
552
strange hangs and failures involving subprocesses. (Andrew Bennetts)
554
* Skip ``utextwrap`` tests when ``sphinx`` breaks text_wrap by an hostile
555
monkey-patch to textwrap.TextWrapper.wordsep_re.
556
(Vincent Ladeuil, #785098)
558
* Multiple ``selftest --exclude`` options are now combined instead of
559
overriding each other. (Vincent Ladeuil, #746991)
561
* Restore some ``FTPTransport`` test coverage by allowing ``pyftpdlib
562
0.6.0`` to be used. Also restore ``medusa`` support while leaving it
563
disabled to make it easier to use if/when we can in the future.
564
(Vincent Ladeuil, #781140)
566
* `TestImportTariffs` no longer uses the real ``$HOME``. This prevents it
567
from polluting ``$HOME/.bzr.log`` or being accidentally influenced by
568
user configuration such as aliases. It still runs with all the user's
569
plugins enabled, as intended.

*****************************
589
.. These may require users to change the way they use Bazaar.
591
* ``bzr-2.4`` has officially dropped support for python2.4 and python2.5.
592
We will continue to maintain ``bzr-2.3`` for people who still need to
593
use those versions of python. (John Arbash Meinel)
598
.. New commands, options, etc that users may wish to try out.
600
* The text compressor used for 2a repositories now has a tweakable
601
parameter that can be set in bazaar.conf.
602
``bzr.groupcompress.max_entries_per_source`` default of 65536.
603
When doing compression, we build up an index of locations to match
604
against. Setting this higher will result in slightly better compression,
605
at a cost of more memory. Note that a value of 65k represents fully
606
sampling a 1MB file. So this only has an effect when compressing texts
607
larger than N*16 bytes. (John Arbash Meinel, #602614)
612
.. Improvements to existing commands, especially improved performance
613
or memory usage, or better results.
615
* ``bzr branch --stacked`` from a smart server uses the network a little
616
more efficiently. For a simple branch it reduces the number of
617
round-trips by about 20%. (Andrew Bennetts)
619
* ``bzr log --line`` scales the width of the author field with the size of
620
the line. This means that the full author name is shown when the
621
environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)
623
* ``bzr pull`` now properly triggers the fast
624
``CHKInventory.iter_changes`` rather than the slow generic
625
inter-Inventory changes. It used to use a ``DirStateRevisionTree`` as
626
one of the source trees, which is faster when we have to read the whole
627
inventory anyway, but much slower when we can get just the delta out of
628
the repository. On a 70k record tree, this changes ``bzr pull`` from 28s
629
down to 17s. (John Arbash Meinel, #780677)
631
* Slightly reduced memory consumption when fetching into a 2a repository
632
by reusing existing caching a little better. (Andrew Bennetts)
634
* Speed up ``bzr status`` by a little bit when there are a couple of
635
modified files. We now track how many files we have seen that need
636
updating, and only rewrite the dirstate file if enough of them have
637
changed. The default is 10, and can be overridden by setting the branch
638
option "``bzr.workingtree.worth_saving_limit``".
639
(Ian Clatworthy, John Arbash Meinel, #380202)
641
* Speed up ``bzr uncommit``. Instead of resetting the dirstate from
642
scratch, use ``update_basis_by_delta``, computing the delta from the
643
repository. (John Arbash Meinel, #780544)
648
.. Fixes for situations where bzr would previously crash or give incorrect
649
or undesirable results.
651
* All Tree types can now be exported as tar.*, zip or directories.
654
* ``bzr merge --no-remember location`` never sets ``submit_branch``.
655
(Vincent Ladeuil, #782169)
657
* ``bzr pull --no-remember location`` never sets
658
``parent_location``. ``bzr push --no-remember location`` never
659
sets ``push_location``. ``bzr send --no-remember
660
submit_location public_location`` never sets ``submit_branch``
661
nor ``public_branch``. (Vincent Ladeuil)
663
* Conflicts involving non-ascii filenames are now properly reported rather
664
than failing with a UnicodeEncodeError. (Martin [GZ], #686161)
666
* Correct parent is now set when using 'switch -b' with bound branches.
667
(A. S. Budden, #513709)
669
* Fix `bzr plugins` regression in bzr 2.4 which resulted in a traceback
670
from writelines on ckj terminals. (Martin [GZ], #754082)
672
* ``WT.inventory`` and ``WT.iter_entries_by_dir()`` was not correctly
673
reporting subdirectories that were tree references (in formats that
674
supported them). (John Arbash Meinel, #764677)
676
* Merging into empty branches now gives an error as this is currently
677
not supported. (Jonathan Riddell, #242175)
679
* Do not show exception to user on pointless commit error.
680
(Jonathan Riddell #317357)
682
* ``WT.update_basis_by_delta`` no longer requires that the deltas match
683
the current WT state. This allows ``update_basis_by_delta`` to be used
684
by more commands than just commit. Updating with a delta allows us to
685
not load the whole inventory, which can take 10+s with large trees.
686
(Jonathan Riddell, John Arbash Meinel, #781168)
688
* ``bzr mv --after old_name new_name`` now works if "new_name" is newly
689
added. (Benoît Pierre)
695
.. Improved or updated documentation.
697
* Restore the workaround for option names including dots (--1.14) which was
698
disabled when we stopped listing --1.9 as a format.
699
(Vincent Ladeuil, #782289)
704
.. Changes that may require updates in plugins or other code that uses
707
* ``annotate_file`` has been deprecated in favor of
708
``annotate_file_revision_tree``. (Jelmer Vernooij, #775598)
710
* ``Branch.fetch`` now takes an optional ``limit`` argument.
711
(Andrew Bennetts, Jelmer Vernooij, #750175)
713
* ``Inter.get`` now raises ``NoCompatibleInter`` if there are no
714
compatible optimisers rather than an instance of the class it is called
715
on. (Jelmer Vernooij)
717
* ``Branch.push`` now takes a ``lossy`` argument.
718
``Branch.lossy_push`` has been removed.
721
* New method ``Repository.get_file_graph`` which can return the
722
per-file revision graph. (Jelmer Vernooij, #775578)
724
* The default implementation of ``Branch`` is now oriented to
725
storing the branch tip. Branch implementations which store the full
726
history should now subclass ``FullHistoryBzrBranch``.
727
``Branch._last_revision_info`` has been renamed to
728
``Branch._read_last_revision_info`` (Jelmer Vernooij)
730
* ``Tree.__iter__`` has been deprecated; use ``Tree.all_file_ids``
731
instead. (Jelmer Vernooij)
733
* ``Tree.get_symlink_target`` now takes an optional ``path``
734
argument. (Jelmer Vernooij)
739
.. Major internal changes, unlikely to be visible to users or plugin
740
developers, but interesting for bzr developers.
742
* ``MutableTree.smart_add`` now uses inventory deltas.
743
(Jelmer Vernooij, #146165)
745
* Removed ``bzrlib.branch._run_with_write_locked_target`` as
746
``bzrlib.cleanup`` provides the same functionality in a more general
747
way. (Andrew Bennetts)
752
.. Fixes and changes that are only relevant to bzr's test framework and
753
suite. This can include new facilities for writing tests, fixes to
754
spurious test failures and changes to the way things should be tested.
756
* A test that was expected to fail but passes instead now counts as a failure
757
catching up with new testtools and subunit handling. (Martin [GZ], #654474)
759
* Make it easier for plugins to reuse the per_workingtree scenarios by
760
restoring the wt_scenarios helper that was accidentally deleted.
761
(Vincent Ladeuil, #783472)
763
* Removed ``test_breakin`` tests that were excessively prone to hanging,
764
did not work on Wine, and partly already disabled.
765
(Martin Pool, #408814, #746985)
767
* Windows locations are different and should be tested accordingly.
768
(Vincent Ladeuil, #788131)
775
This is the second beta of the 2.4 series, leading to a 2.4.0 release in
776
August 2011. Beta releases are suitable for everyday use but may cause some
777
incompatibilities with plugins.
779
This release includes all bug fixed in previous series known at the time of
783
External Compatibility Breaks
784
*****************************
786
.. These may require users to change the way they use Bazaar.
788
* Two command synonyms for ``bzr branch`` have been deprecated, to avoid
789
confusion and to allow the names to later be reused. The removed names
790
are: ``get`` and ``clone``. (Martin Pool, #506265)
795
.. New commands, options, etc that users may wish to try out.
797
* ``bzr commit`` now supports a ``--lossy`` argument that can be used
798
to discard any data that can not be natively represented when committing
799
to a foreign VCS. (Jelmer Vernooij, #587721)
804
.. Improvements to existing commands, especially improved performance
805
or memory usage, or better results.
807
* ``bzr merge`` in large trees is now significantly faster. On a 70k entry
808
tree, the time went from ~3min down to 30s. This also effects ``bzr pull``
809
and ``bzr update`` since they use the same merge logic to update the
810
WorkingTree. (John Arbash Meinel, #759091)
812
* ``bzr revert`` now properly uses ``bzr status``'s optimized
813
``iter_changes``. This can be a significant performance difference (33s
814
to 5s on large trees). (John Arbash Meinel, #759096)
816
* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
817
the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
818
being handed off to the remote server anyway (xmlrpc has been mapping
819
``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
820
than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
821
months now.) By doing it ourselves, we can cut out substantial startup
822
time. From Netherlands to London it was taking 368ms to do the XMLRPC
823
call as much as 2s from Sydney. You can test the local logic by using
824
``-Dlaunchpad``. (John Arbash Meinel, #397739)
826
* When building a new WorkingTree (such as during ``bzr co`` or
827
``bzr branch``) we now properly store the stat and hash of files that
828
are old enough. This saves a fair amount of time on the first
829
``bzr status`` (on a 500MB tree, it saves about 30+s).
830
(John Arbash Meinel, #740932)
836
.. Fixes for situations where bzr would previously crash or give incorrect
837
or undesirable results.
839
* Arguments that can't be decoded to unicode in the current posix locale give
840
a clearer error message without a traceback. (Martin [gz], #745712)
842
* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
843
mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
844
these default values aren't relied on very often so this probably
845
wasn't causing any trouble. (Andrew Bennetts)
847
* ``bzr log`` now works on revisions which are not in the current branch.
848
(Matt Giuca, #241998)
850
* Don't rewrite the dirstate file when non-interesting changes have
851
occurred. This can significantly improve 'bzr status' times when there
852
are only small changes to a large tree.
853
(Ian Clatworthy, John Arbash Meinel, #380202)
855
* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
857
* ``bzrlib.merge.Merge`` now calls ``iter_changes`` without
858
``include_unversioned=True``. This makes it significantly faster in many
859
cases, because it only looks at modified files, rather than building
860
information about all files. This can cause failures in other
861
TreeTransform code, because it had been expecting to know the names of
862
things which had not changed (such as parent directories). All cases we
863
know about so far have been fixed, but there may be fallout for edge
864
cases that we are missing. (John Arbash Meinel, #759091)
866
* ``SFTPTransport`` is more pro-active about closing file-handles. This
867
reduces the chance of having threads fail from async requests while
868
running the test suite. (John Arbash Meinel, #656170)
870
* Standalone bzr.exe installation on Windows: user can put additional python
871
libraries into ``site-packages`` subdirectory of the installation directory,
872
this might be required for "installing" extra dependencies for some plugins.
873
(Alexander Belchenko, #743256)
875
* ``transform.revert()`` has been updated to use
876
``wt.iter_changes(basis_tree)`` rather than
877
``basis_tree.iter_changes(wt)``. This allows the optimized code path to
878
kick in, improving ``bzr revert`` times significantly (33s to 4s on
879
large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)
881
* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
882
parameter. If supplied, when the transform is applied, it will then call
883
``self._tree._observed_sha1`` for those files. This lets us update the
884
hash-cache for content that we create, preventing us from re-reading the
885
content in the next ``bzr status``. (John Arbash Meinel, #740932)
890
* Added a section about using a shared SSH account on a server for bzr+ssh
891
access. (Russell Smith)
893
* The documentation now recommends using SSH rather than SFTP in the
894
tutorials and the examples, because that will generally be much faster
895
and better in cases where it can be used. SFTP is still available and
896
mentioned as an alternative. (Martin Pool, #636712)
901
.. Changes that may require updates in plugins or other code that uses
904
* ``Branch.update_revisions`` has been made private and should no
905
longer be used by external users. Use ``Branch.pull`` or ``Branch.push``
906
instead. (Jelmer Vernooij, #771765)
908
* Commands now have an `invoked_as` attribute, showing the name under
909
which they were called before alias expansion.
912
* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
915
* If you call `bzrlib.initialize` but forget to enter the resulting object
916
as a context manager, bzrlib will now be initialized anyhow.
917
(Previously simple programs calling bzrlib might find the library was
918
mysteriously silent.)
921
* Inventory-specific functionality has been split out of ``Tree`` into
922
a new ``InventoryTree`` class. Tree instances no longer
923
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
925
* Inventory-specific functionality has been split out of ``RevisionTree``
926
into a new ``InventoryRevisionTree`` class. RevisionTree instances no
927
longer necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
929
* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)
931
* ``revision_graph_can_have_wrong_parents`` is now an attribute
932
on ``RepositoryFormat`` rather than a method on ``Repository``.
935
* ``Testament`` now takes a ``tree`` rather than an
936
``inventory``. (Jelmer Vernooij, #762608)
938
* ``TestCase.failUnlessExists`` and ``failIfExists`` are deprecated in
939
favour of ``assertPathExists`` and ``assertPathDoesNotExist``
943
* The ``revno`` parameter of ``log.LogRevision`` may now be None,
944
representing a revision which is not in the current branch.
945
(Matt Giuca, #241998)
947
* The various knit pack repository format classes have been moved
948
from ``bzrlib.repofmt.pack_repo`` to
949
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)
951
* ``RevisionTree`` now has a new method ``get_file_revision``.
954
* ``WorkingTree`` no longer provides an ``inventory``. Instead,
955
all inventory-related functionality is now on the subclass
956
``InventoryWorkingTree`` that all native Bazaar working tree
957
implementations derive from. (Jelmer Vernooij)
962
.. Major internal changes, unlikely to be visible to users or plugin
963
developers, but interesting for bzr developers.
965
* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
966
functions on Linux, but they are wrapped on Windows so that fstat
967
matches lstat results across all python versions.
970
* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
971
happened to be updated as a side-effect of commit, but if we start using
972
the function elsewhere we might as well do it directly.
978
.. Fixes and changes that are only relevant to bzr's test framework and
979
suite. This can include new facilities for writing tests, fixes to
980
spurious test failures and changes to the way things should be tested.
982
* Stop using `failIf`, `failUnless`, `failIfEqual`, etc, that give
983
`PendingDeprecationWarnings` on Python2.7.
984
(Martin Pool, #760435)
992
This is the first beta of the 2.4 series, leading up to a 2.4.0
993
release in August 2011. Beta releases are suitable for everyday use
994
but may cause some incompatibilities with plugins. Some plugins may need
995
small updates to work with 2.4b1.
997
External Compatibility Breaks
998
*****************************
1005
* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
1006
in GNU format. See ``bzr help changelog_merge`` for details.
1009
* Configuration options can now use references to other options in the same
1010
file by enclosing them with curly brackets (``{other_opt}``). This makes it
1011
possible to use, for example,
1012
``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
1013
using a loom. During the beta period, the default behaviour is to disable
1014
this feature. It can be activated by declaring ``bzr.config.expand = True``
1015
in ``bazaar.conf``. (Vincent Ladeuil)
1017
* External merge tools can now be configured in bazaar.conf. See
1018
``bzr help configuration`` for more information. (Gordon Tyler, #489915)
1020
* The ``lp:`` directory service now supports Launchpad's QA staging.
1021
(Jelmer Vernooij, #667483)
1026
* A new hidden command ``bzr repair-workingtree``. This is a way to force
1027
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
1028
workaround. (John Arbash Meinel)
1030
* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
1031
This allows formats from plugins (such as looms) to efficiently tell the
1032
client which revisions need to be fetched. (Andrew Bennetts)
1034
* Branching, merging and pulling a branch now copies revisions named in
1035
tags, not just the tag metadata. (Andrew Bennetts, #309682)
1037
* ``bzr cat-revision`` no longer requires a working tree.
1038
(Jelmer Vernooij, #704405)
1040
* ``bzr export --per-file-timestamps`` for .tar.gz files will now
1041
override the mtime for trees exported on Python 2.7 and later, which
1042
expose the 'mtime' field in gzip files. This makes the output of
1043
``bzr export --per-file-timestamps`` for a particular tree
1044
deterministic. (Jelmer Vernooij, #711226)
1046
* ``bzr export --format=zip`` can now export to standard output,
1047
like the other exporters can. (Jelmer Vernooij, #513752)
1049
* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
1050
(Jelmer Vernooij, #551714)
1052
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
1053
sped up dramatically for large trees. Iterating by dir is not the best
1054
way to load data from a CHK inventory, so it preloads all the items in
1055
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
1056
of CHK data, down to just 150MB.) This has noticeable affects for things
1057
like building checkouts, etc. (John Arbash Meinel, #737234)
1062
* A MemoryError thrown on the server during a remote operation will now be
1063
usefully reported, and other unexpected errors will include the class name.
1064
(Martin [gz], #722416)
1066
* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
1067
(Andrew King, #537442)
1069
* ``bzr export`` to zip files will now set a mode on directories.
1070
(Jelmer Vernooij, #207253)
1072
* ``bzr export`` to tgz files will only write out the basename of the
1073
tarfile to the gzip file. (Jelmer Vernooij, #102234)
1075
* ``bzr push --overwrite`` with an older revision specified will now correctly
1076
roll back the target branch. (Jelmer Vernooij, #386576)
1078
* ``bzr lp-propose`` can now propose merges against packaging branches on
1079
Launchpad without requiring the target branch to be specified.
1080
(Jelmer Vernooij, #704647)
1082
* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
1083
instead leave setting the reviewer up to Launchpad if it was not specified.
1084
(Jelmer Vernooij, #583772)
1086
* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
1087
(Jelmer Vernooij, #213185)
1089
* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
1090
paths, however they may still print junk if not on a UTF-8 terminal.
1091
(Martin [gz], #707954)
1093
* ``bzr reconfigure --unstacked`` now copies revisions (and their
1094
ancestors) named in tags into the unstacked repository, not just the
1095
ancestry of the branch's tip. (Andrew Bennetts, #401646)
1097
* ``bzr serve`` no longer crashes when a server_started hook is installed and
1098
IPv6 support is available on the system. (Jelmer Vernooij, #293697)
1100
* ``bzr status`` will not rewrite the dirstate file if it only has
1101
'trivial' changes. (Currently limited to dir updates and newly-added
1102
files changing state.) This saves a bit of time for regular operations.
1103
eg. ``bzr status`` in a 100k tree takes 1.4s to compute the status, but 1s
1104
to re-save the dirstate file. (John Arbash Meinel, #765881)
1106
* ``bzr tags`` will no longer choke on branches with ghost revisions in
1107
their mainline and tags on revisions not in the branch ancestry.
1108
(Jelmer Vernooij, #397556)
1110
* ``bzr whoami`` will now display an error if both a new identity and
1111
``--email`` were specified. (Jelmer Vernooij, #680449)
1113
* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
1114
(Vincent Ladeuil, #706835)
1116
* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
1118
(Martin Pool, #586341)
1120
* Plugins incompatible with the current version of bzr no longer produce a
1121
warning on every command invocation. Instead, a message is shown by
1122
``bzr plugins`` and in crash reports.
1123
(#704195, Martin Pool)
1125
* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
1126
preserves the identity of default parameter values.
1127
(Andrew Bennetts, #718569)
1129
* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
1130
containing no rows. (Eric Siegerman, #715508)
1132
* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
1133
without an explicit public location. (Max Bowsher)
1135
* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
1136
number of available processors. (Jelmer Vernooij, #693140)
1141
* Added ``Branch.heads_to_fetch`` method. Implementations of the Branch API
1142
must now inherit or implement this method. (Andrew Bennetts, #721328)
1144
* Added ``bzrlib.mergetools`` module with helper functions for working with
1145
the list of external merge tools. (Gordon Tyler, #489915)
1147
* All methods and arguments that were deprecated before 2.0
1148
have been removed. (Jelmer Vernooij)
1150
* Branch formats should now be registered on the format registry
1151
(``bzrlib.branch.format_registry``) rather than using the class
1152
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)
1154
* ``Branch.set_revision_history`` is now deprecated.
1157
* ``BranchFormat.supports_leaving_lock()`` and
1158
``RepositoryFormat.supports_leaving_lock`` flags have been added.
1161
* ``Branch.fetch`` implementations must now accept an optional
1162
``fetch_tags`` keyword argument. (Andrew Bennetts)
1164
* ``Branch.import_last_revision_info`` is deprecated. Use the
1165
``import_last_revision_info_and_tags`` method instead.
1168
* Because it was too specific to BzrDir implementations,
1169
``ControlDir.sprout`` no longer has a default implementation; it now
1170
raises ``NotImplementedError``. (Jelmer Vernooij, #717937)
1172
* ``bzrlib.deprecated_graph`` has been removed. ``bzrlib.graph``
1173
scales better tree and should be used instead.
1174
(Jelmer Vernooij, #733612)
1176
* ``ControlDirFormat.register_format`` has been removed. Instead,
1177
``Prober`` implementations should now implement a ``known_formats``
1178
method. (Jelmer Vernooij)
1180
* ControlDirFormats can now provide a ``check_status`` method and
1181
raise a custom exception or warning when an unsupported or deprecated
1182
format is being opened. (Jelmer Vernooij, #731311)
1184
* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
1185
Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
1186
``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
1187
instead. (Jelmer Vernooij, #721971)
1189
* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
1190
indicates whether the components of the bzrdir can be upgraded
1191
independent of the ``BzrDir``. (Jelmer Vernooij)
1193
* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
1194
now deprecated in favour of the ``BzrProber.formats`` format registry.
1197
* ``ControlDir`` implementations no longer have to provide the
1198
``get_branch_transport``, ``get_workingtree_transport`` and
1199
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)
1201
* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
1202
``bzrlib.controldir``. (Jelmer Vernooij)
1204
* Repository formats can now provide
1205
``_get_extra_interrepo_test_combinations`` in the same module
1206
to provide extra test combinations for ``bzrlib.tests.per_repository``.
1209
* Repository formats should now be registered on the format registry
1210
(``bzrlib.repository.format_registry``) rather than using the class
1211
methods on ``RepositoryFormat``. (Jelmer Vernooij)
1213
* Repository formats can now indicate they do not support the full
1214
VersionedFiles API by setting the ``supports_full_versioned_files``
1215
attribute to False. A subset of the VersionedFiles API
1216
(signatures and text graphs) still needs to be supported.
1219
* Repository formats have a new method ``is_deprecated`` that
1220
implementations can override to return True to trigger a deprecation
1221
warning. (Jelmer Vernooij)
1223
* The ``revision_id`` parameter of
1224
``Repository.search_missing_revision_ids`` and
1225
``InterRepository.search_missing_revision_ids`` is deprecated. It is
1226
replaced by the ``revision_ids`` parameter. (Andrew Bennetts)
1228
* Working tree formats should now be registered on the format registry
1229
(``bzrlib.working_tree.format_registry``) rather than using the class
1230
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)
1232
* Exporting may now be done with a generator
1233
(``bzrlib.export.get_export_generator``) (Geoff/xaav, #791005)
1238
* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
1239
out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
1240
outside of tests. This class makes it easier to track exceptions in threads
1241
by catching them so they can be re-raised in the controlling thread. It's
1242
available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)
1244
* Correctly propagate malloc failures from diff-delta.c code as MemoryError
1245
so OOM conditions during groupcompress are clearly reported. This entailed a
1246
