16
.. 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.
38
.. Improved or updated documentation.
43
.. Changes that may require updates in plugins or other code that uses
49
.. Major internal changes, unlikely to be visible to users or plugin
50
developers, but interesting for bzr developers.
55
.. Fixes and changes that are only relevant to bzr's test framework and
56
suite. This can include new facilities for writing tests, fixes to
57
spurious test failures and changes to the way things should be tested.
59
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
60
cleanly and reliably allows tests using `BranchBuilder` to construct
61
branches that e.g. rename files out of a directory and unversion that
62
directory in the same revision. Previously some changes were impossible
63
due to the order that `build_snapshot` performs its actions.
66
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
67
just compares the bytes in the dirstate file to its pristine state,
68
rather than opening the WorkingTree and calling ``last_revision()``.
69
This reduces the overall test suite time by about 10% on my laptop.
78
This is the fifth (and last) beta of the 2.4 series leading to
79
2.4.0 release in Auguest 2011. Beta releases are suitable for
80
everyday use but may cause some incompatibilities with plugins.
82
This release includes all bug fixed in previous series known at
83
the time of this release.

86
*****************************
93
* New command ``verify-signatures`` to check if all commits or specified commits
94
have digital signatures from trusted keys. Requires python-gpgme to be
97
* New option ``--signatures`` for ``bzr log`` to display digital signature
98
verification results for each commit.
100
* Config option acceptable_keys to list which GPG keys are verified as trusted.
102
* Config option validate_signatures_in_log to always show signatures in
108
* ``Branch.open`` is now about 3x faster (about 2ms instead of 6.5ms).
114
* Display a proper error message when a config file content cannot be
115
decoded as UTF-8 or when it cannot be parsed.
116
(Vincent Ladeuil, #502060, #688677, #797246)
118
* Generate a single conflict (instead of two) when merging a branch
119
modifying and renaming a file in a branch that deleted it (or vice-versa).
120
(Vincent Ladeuil, #688101)
122
* Give a more helpful message when the bzr executable doesn't match the
123
library. (This typically happens because of a misconfigured PYTHONPATH
124
or half-installed bzr.)
125
(Martin Pool, #804553)
127
* Properly load utf8-encoded config files. (Vincent Ladeuil, #799212)
129
* ``GraphThunkIdsToKeys.merge_sort`` now properly returns
130
keys rather than ids. (Jelmer Vernooij, #799677)
132
* ``TreeTransformBase.fixup_new_roots`` can now check that a tree root
133
is present. (Jelmer Vernooij, #801257)
138
* New attributes ``WorkingTreeFormat.supports_versioned_directories`` and
139
``RepositoryFormat.supports_versioned_directories``.
140
(Jelmer Vernooij, #765815)
142
* The "revno" field type when using the python version-info format is now
143
a string (to handle dotted revnos) (Benoît Pierre, #796259)
148
* Start implementing localization, starting with command help text (but not
149
the command options themselves). This will allow bootstrapping the bzr
150
internationalization process. (Inada Naoki)
155
* Fix test failures when running as a homeless user (debian buildd). Tests
156
leaking into ``${HOME}/.bzr.log`` should be detected properly now.
157
(Vincent Ladeuil, #798698)
164
This is the fourth beta of the 2.4 series, leading to a 2.4.0 release in
165
August 2011. Beta releases are suitable for everyday use but may cause some

*****************************
175
.. These may require users to change the way they use Bazaar.
177
* Do not treat configuration option 'check_signatures = require' as if
178
it were 'create_signatures = always' (Jonathan Riddell)
183
.. New commands, options, etc that users may wish to try out.
185
* Hooks have been added for config stacks: ``get``, ``set`` and ``remove``
186
are called when an option is respectively read, modified or deleted. Also
187
added ``load`` and ``save`` hooks for config stores, called when the
188
stores are loaded or saved. (Vincent Ladeuil)
190
* New hook server_exception in bzrlib.smart.server to catch any
191
exception caused while running bzr serve.
192
(Jonathan Riddell, #274578)
194
* New hook set_commit_message in bzrlib.msgeditor to set a commit message
195
and revision properties. (Jonathan Riddell, #274578)
197
* Support ``-S`` as an alias for ``--short`` for the ``log`` and
198
``missing`` commands. (Martin von Gagern, #38655)
203
.. Improvements to existing commands, especially improved performance
204
or memory usage, or better results.
206
* ``bzr annotate`` can be run without setting whoami data first.
207
(Jonathan Riddell, #667408)
212
.. Fixes for situations where bzr would previously crash or give incorrect
213
or undesirable results.
215
* Bazaar can now detect when a lock file is held by a dead process
216
originating from the same machine, and steal the lock after printing a
217
message to the user. This is off by default, for safety, but can be
218
turned on by setting the configuration variable ``locks.steal_dead`` to
220
(Martin Pool, #220464)
222
* ``bzr version-info`` now works when the tree is on a dotted revno.
223
(Benoît Pierre, #796259)
225
* Credentials in the log output produced by ``-Dhttp`` are masked so users
226
can more freely post them in bug reports. (Vincent Ladeuil, #723074)
228
* Fix a race condition for ``server_started`` hooks leading to a spurious
229
test failure. (Vincent Ladeuil, #789167)
231
* Fix exporting subdirectory with ``--per-file-timestamps``.
232
(Szilveszter Farkas, #795557)
234
* Handle files that get created but don't get used during TreeTransform.
235
``open()`` can create a file, and still raise an exception before it
236
returns. So anything we might have created, make sure we destroy during
237
``finalize()``. (Martin [gz], #597686)
239
* ``pack_repo`` now uses ``Transport.move`` instead of
240
``Transport.rename``, deleting any existing targets even on SFTP.
241
(Martin von Gagern, #421776)
243
* Pass the ``build_mo`` command to the rest of the setup() calls in
244
setup.py. The ``bdist_wininst`` and ``py2exe`` code paths were failing
245
because ``build_mo`` became a required step that they didn't know about.
246
(John Arbash Meinel, #787122)
248
* Preserve existing ``root-id`` when merging an unrelated branch.
249
(Aaron Bentley, #806356)
251
* Properly avoid re-adding a file after it changes case on CICP
252
filesystems. (John Arbash Meinel, #798130)
254
* Reports the original error when an InvalidHttpResponse exception is
255
encountered to facilitate debug. (Vincent Ladeuil, #788530)
257
* Reports a non-existant file error when trying to merge in a file
258
that does not exist. (Jonathan Riddell, #330063)
260
* ``UIFactory.prompt``, ``UIFactory.get_username``,
261
``UIFactory.get_password`` and ``UIFactory.get_boolean`` now require a
262
unicode prompt to be passed in. (Jelmer Vernooij, #592083)
264
* Support merging into the empty tree. (Aaron Bentley, #595328)
269
.. Improved or updated documentation.
271
* Improve documentation of ``bzr merge --force``.
272
(Neil Martinsen-Burrell, #767307)
274
* Make docs for configuration options for digital signatures match
275
reality. (Jonathan Riddell)
277
* Add user-guide page on GPG signatures. (Jonathan Riddell)
282
.. Changes that may require updates in plugins or other code that uses
285
* Checking for a file id in a `Tree` or `Inventory` using ``in`` is now
286
deprecated. Instead, use `has_id`.
289
* Exporters are now all exposed as generators, rather than as single-call
290
functions, so that calling code can take stream the output.
293
* Information about held lockdir locks returned from eg `LockDir.peek` is
294
now represented as a `LockHeldInfo` object, rather than a plain
298
* Remove `file_status` function.
301
* ``Repository.iter_reverse_revision_history`` is now deprecated.
302
Use ``Graph.iter_lefthand_ancestry`` instead.
303
(Jelmer Vernooij, #739481)
305
* ``Repository.get_ancestry`` has been deprecated. Use
306
``Graph.iter_ancestry`` instead.
307
(Jelmer Vernooij, #784511)
312
.. Major internal changes, unlikely to be visible to users or plugin
313
developers, but interesting for bzr developers.
315
* ``tools/check-newsbugs.py`` accepts a ``--browser`` option to open
316
corresponding launchpad pages in a browser. (Vincent Ladeuil)
321
.. Fixes and changes that are only relevant to bzr's test framework and
322
suite. This can include new facilities for writing tests, fixes to
323
spurious test failures and changes to the way things should be tested.
325
* A `ImportTariffTestCase` base class has been added in
326
``bzrlib.tests.test_import_tariff``, which can be used for import tariff
327
tests in plugins. (Jelmer Vernooij, #793465)
329
* Fix deadlock in `TestImportTariffs.test_simple_serve` when stderr gets
330
more output than fits in the default buffer. This was happening on the
331
Windows buildslave, and could easily happen in other circumstances where
332
the default OS buffer size for pipes is small or the ``python -v``
333
output is large. (Andrew Bennetts, #784802)
335
* Fix spurious test failure on OSX for WorkingTreeFormat2.
336
(Vincent Ladeuil, #787942)
338
* Re-target ``bb.test_merge.TestMerge.test_merge_reversed_revision_range``
339
and rewrite it as a parameterized test to avoid unrelated failures.
340
(Vincent Ladeuil, #795456)
342
* Show log file contents from subprocesses started by
343
`start_bzr_subprocess` in test failure details. This may help diagnose
344
strange hangs and failures involving subprocesses. (Andrew Bennetts)
346
* Skip ``utextwrap`` tests when ``sphinx`` breaks text_wrap by an hostile
347
monkeypatch to textwrap.TextWrapper.wordsep_re.
348
(Vincent Ladeuil, #785098)
350
* Multiple ``selftest --exclude`` options are now combined instead of
351
overriding each other. (Vincent Ladeuil, #746991)
353
* Restore some ``FTPTransport`` test coverage by allowing ``pyftpdlib
354
0.6.0`` to be used. Also restore ``medusa`` support while leaving it
355
disabled to make it easier to use if/when we can in the future.
356
(Vincent Ladeuil, #781140)
358
* `TestImportTariffs` no longer uses the real ``$HOME``. This prevents it
359
from polluting ``$HOME/.bzr.log`` or being accidentally influenced by
360
user configuration such as aliases. It still runs with all the user's
361
plugins enabled, as intended.
362
(Vincent Ladeuil, Andrew Bennetts, #789505)
370
This is the third beta of the 2.4 series, leading to a 2.4.0 release in
371
August 2011. Beta releases are suitable for everyday use but may cause some

*****************************
381
.. These may require users to change the way they use Bazaar.
383
* ``bzr-2.4`` has officially dropped support for python2.4 and python2.5.
384
We will continue to maintain ``bzr-2.3`` for people who still need to
385
use those versions of python. (John Arbash Meinel)
390
.. New commands, options, etc that users may wish to try out.
392
* The text compressor used for 2a repositories now has a tweakable
393
parameter that can be set in bazaar.conf.
394
``bzr.groupcompress.max_entries_per_source`` default of 65536.
395
When doing compression, we build up an index of locations to match
396
against. Setting this higher will result in slightly better compression,
397
at a cost of more memory. Note that a value of 65k represents fully
398
sampling a 1MB file. So this only has an effect when compressing texts
399
larger than N*16 bytes. (John Arbash Meinel, #602614)
404
.. Improvements to existing commands, especially improved performance
405
or memory usage, or better results.
407
* ``bzr branch --stacked`` from a smart server uses the network a little
408
more efficiently. For a simple branch it reduces the number of
409
round-trips by about 20%. (Andrew Bennetts)
411
* ``bzr log --line`` scales the width of the author field with the size of
412
the line. This means that the full author name is shown when the
413
environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)
415
* ``bzr pull`` now properly triggers the fast
416
``CHKInventory.iter_changes`` rather than the slow generic
417
inter-Inventory changes. It used to use a ``DirStateRevisionTree`` as
418
one of the source trees, which is faster when we have to read the whole
419
inventory anyway, but much slower when we can get just the delta out of
420
the repository. On a 70k record tree, this changes ``bzr pull`` from 28s
421
down to 17s. (John Arbash Meinel, #780677)
423
* Slightly reduced memory consumption when fetching into a 2a repository
424
by reusing existing caching a little better. (Andrew Bennetts)
426
* Speed up ``bzr status`` by a little bit when there are a couple of
427
modified files. We now track how many files we have seen that need
428
updating, and only rewrite the dirstate file if enough of them have
429
changed. The default is 10, and can be overridden by setting the branch
430
option "``bzr.workingtree.worth_saving_limit``".
431
(Ian Clatworthy, John Arbash Meinel, #380202)
433
* Speed up ``bzr uncommit``. Instead of resetting the dirstate from
434
scratch, use ``update_basis_by_delta``, computing the delta from the
435
repository. (John Arbash Meinel, #780544)
440
.. Fixes for situations where bzr would previously crash or give incorrect
441
or undesirable results.
443
* All Tree types can now be exported as tar.*, zip or directories.
446
* ``bzr merge --no-remember location`` never sets ``submit_branch``.
447
(Vincent Ladeuil, #782169)
449
* ``bzr pull --no-remember location`` never sets
450
``parent_location``. ``bzr push --no-remember location`` never
451
sets ``push_location``. ``bzr send --no-remember
452
submit_location public_location`` never sets ``submit_branch``
453
nor ``public_branch``. (Vincent Ladeuil)
455
* Conflicts involving non-ascii filenames are now properly reported rather
456
than failing with a UnicodeEncodeError. (Martin [GZ], #686161)
458
* Correct parent is now set when using 'switch -b' with bound branches.
459
(A. S. Budden, #513709)
461
* Fix `bzr plugins` regression in bzr 2.4 which resulted in a traceback
462
from writelines on ckj terminals. (Martin [GZ], #754082)
464
* ``WT.inventory`` and ``WT.iter_entries_by_dir()`` was not correctly
465
reporting subdirectories that were tree references (in formats that
466
supported them). (John Arbash Meinel, #764677)
468
* Merging into empty branches now gives an error as this is currently
469
not supported. (Jonathan Riddell, #242175)
471
* Do not show exception to user on pointless commit error.
472
(Jonathan Riddell #317357)
474
* ``WT.update_basis_by_delta`` no longer requires that the deltas match
475
the current WT state. This allows ``update_basis_by_delta`` to be used
476
by more commands than just commit. Updating with a delta allows us to
477
not load the whole inventory, which can take 10+s with large trees.
478
(Jonathan Riddell, John Arbash Meinel, #781168)
480
* ``bzr mv --after old_name new_name`` now works if "new_name" is newly
481
added. (Benoît Pierre)
487
.. Improved or updated documentation.
489
* Restore the workaround for option names including dots (--1.14) which was
490
disabled when we stopped listing --1.9 as a format.
491
(Vincent Ladeuil, #782289)
496
.. Changes that may require updates in plugins or other code that uses
499
* ``annotate_file`` has been deprecated in favor of
500
``annotate_file_revision_tree``. (Jelmer Vernooij, #775598)
502
* ``Branch.fetch`` now takes an optional ``limit`` argument.
503
(Andrew Bennetts, Jelmer Vernooij, #750175)
505
* ``Inter.get`` now raises ``NoCompatibleInter`` if there are no
506
compatible optimisers rather than an instance of the class it is called
507
on. (Jelmer Vernooij)
509
* ``Branch.push`` now takes a ``lossy`` argument.
510
``Branch.lossy_push`` has been removed.
513
* New method ``Repository.get_file_graph`` which can return the
514
per-file revision graph. (Jelmer Vernooij, #775578)
516
* The default implementation of ``Branch`` is now oriented to
517
storing the branch tip. Branch implementations which store the full
518
history should now subclass ``FullHistoryBzrBranch``.
519
``Branch._last_revision_info`` has been renamed to
520
``Branch._read_last_revision_info`` (Jelmer Vernooij)
522
* ``Tree.__iter__`` has been deprecated; use ``Tree.all_file_ids``
523
instead. (Jelmer Vernooij)
525
* ``Tree.get_symlink_target`` now takes an optional ``path``
526
argument. (Jelmer Vernooij)
531
.. Major internal changes, unlikely to be visible to users or plugin
532
developers, but interesting for bzr developers.
534
* ``MutableTree.smart_add`` now uses inventory deltas.
535
(Jelmer Vernooij, #146165)
537
* Removed ``bzrlib.branch._run_with_write_locked_target`` as
538
``bzrlib.cleanup`` provides the same functionality in a more general
539
way. (Andrew Bennetts)
544
.. Fixes and changes that are only relevant to bzr's test framework and
545
suite. This can include new facilities for writing tests, fixes to
546
spurious test failures and changes to the way things should be tested.
548
* A test that was expected to fail but passes instead now counts as a failure
549
catching up with new testtools and subunit handling. (Martin [GZ], #654474)
551
* Make it easier for plugins to reuse the per_workingtree scenarios by
552
restoring the wt_scenarios helper that was accidentally deleted.
553
(Vincent Ladeuil, #783472)
555
* Removed ``test_breakin`` tests that were excessively prone to hanging,
556
did not work on Wine, and partly already disabled.
557
(Martin Pool, #408814, #746985)
559
* Windows locations are different and should be tested accordingly.
560
(Vincent Ladeuil, #788131)

*****************************
578
.. These may require users to change the way they use Bazaar.
580
* Two command synonyms for ``bzr branch`` have been deprecated, to avoid
581
confusion and to allow the names to later be reused. The removed names
582
are: ``get`` and ``clone``. (Martin Pool, #506265)
587
.. New commands, options, etc that users may wish to try out.
589
* ``bzr commit`` now supports a ``--lossy`` argument that can be used
590
to discard any data that can not be natively represented when committing
591
to a foreign VCS. (Jelmer Vernooij, #587721)
596
.. Improvements to existing commands, especially improved performance
597
or memory usage, or better results.
599
* ``bzr merge`` in large trees is now significantly faster. On a 70k entry
600
tree, the time went from ~3min down to 30s. This also effects ``bzr pull``
601
and ``bzr update`` since they use the same merge logic to update the
602
WorkingTree. (John Arbash Meinel, #759091)
604
* ``bzr revert`` now properly uses ``bzr status``'s optimized
605
``iter_changes``. This can be a significant performance difference (33s
606
to 5s on large trees). (John Arbash Meinel, #759096)
608
* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
609
the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
610
being handed off to the remote server anyway (xmlrpc has been mapping
611
``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
612
than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
613
months now.) By doing it ourselves, we can cut out substantial startup
614
time. From Netherlands to London it was taking 368ms to do the XMLRPC
615
call as much as 2s from Sydney. You can test the local logic by using
616
``-Dlaunchpad``. (John Arbash Meinel, #397739)
618
* When building a new WorkingTree (such as during ``bzr co`` or
619
``bzr branch``) we now properly store the stat and hash of files that
620
are old enough. This saves a fair amount of time on the first
621
``bzr status`` (on a 500MB tree, it saves about 30+s).
622
(John Arbash Meinel, #740932)
628
.. Fixes for situations where bzr would previously crash or give incorrect
629
or undesirable results.
631
* Arguments that can't be decoded to unicode in the current posix locale give
632
a clearer error message without a traceback. (Martin [gz], #745712)
634
* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
635
mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
636
these default values aren't relied on very often so this probably
637
wasn't causing any trouble. (Andrew Bennetts)
639
* ``bzr log`` now works on revisions which are not in the current branch.
640
(Matt Giuca, #241998)
642
* Don't rewrite the dirstate file when non-interesting changes have
643
occurred. This can significantly improve 'bzr status' times when there
644
are only small changes to a large tree.
645
(Ian Clatworthy, John Arbash Meinel, #380202)
647
* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
649
* ``bzrlib.merge.Merge`` now calls ``iter_changes`` without
650
``include_unversioned=True``. This makes it significantly faster in many
651
cases, because it only looks at modified files, rather than building
652
information about all files. This can cause failures in other
653
TreeTransform code, because it had been expecting to know the names of
654
things which had not changed (such as parent directories). All cases we
655
know about so far have been fixed, but there may be fallout for edge
656
cases that we are missing. (John Arbash Meinel, #759091)
658
* ``SFTPTransport`` is more pro-active about closing file-handles. This
659
reduces the chance of having threads fail from async requests while
660
running the test suite. (John Arbash Meinel, #656170)
662
* Standalone bzr.exe installation on Windows: user can put additional python
663
libraries into ``site-packages`` subdirectory of the installation directory,
664
this might be required for "installing" extra dependencies for some plugins.
665
(Alexander Belchenko, #743256)
667
* ``transform.revert()`` has been updated to use
668
``wt.iter_changes(basis_tree)`` rather than
669
``basis_tree.iter_changes(wt)``. This allows the optimized code path to
670
kick in, improving ``bzr revert`` times significantly (33s to 4s on
671
large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)
673
* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
674
parameter. If supplied, when the transform is applied, it will then call
675
``self._tree._observed_sha1`` for those files. This lets us update the
676
hash-cache for content that we create, preventing us from re-reading the
677
content in the next ``bzr status``. (John Arbash Meinel, #740932)
682
* Added a section about using a shared SSH account on a server for bzr+ssh
683
access. (Russell Smith)
685
* The documentation now recommends using SSH rather than SFTP in the
686
tutorials and the examples, because that will generally be much faster
687
and better in cases where it can be used. SFTP is still available and
688
mentioned as an alternative. (Martin Pool, #636712)
693
.. Changes that may require updates in plugins or other code that uses
696
* ``Branch.update_revisions`` has been made private and should no
697
longer be used by external users. Use ``Branch.pull`` or ``Branch.push``
698
instead. (Jelmer Vernooij, #771765)
700
* Commands now have an `invoked_as` attribute, showing the name under
701
which they were called before alias expansion.
704
* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
707
* If you call `bzrlib.initialize` but forget to enter the resulting object
708
as a context manager, bzrlib will now be initialized anyhow.
709
(Previously simple programs calling bzrlib might find the library was
710
mysteriously silent.)
713
* Inventory-specific functionality has been split out of ``Tree`` into
714
a new ``InventoryTree`` class. Tree instances no longer
715
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
717
* Inventory-specific functionality has been split out of ``RevisionTree``
718
into a new ``InventoryRevisionTree`` class. RevisionTree instances no
719
longer necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
721
* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)
723
* ``revision_graph_can_have_wrong_parents`` is now an attribute
724
on ``RepositoryFormat`` rather than a method on ``Repository``.
727
* ``Testament`` now takes a ``tree`` rather than an
728
``inventory``. (Jelmer Vernooij, #762608)
730
* ``TestCase.failUnlessExists`` and ``failIfExists`` are deprecated in
731
favour of ``assertPathExists`` and ``assertPathDoesNotExist``
735
* The ``revno`` parameter of ``log.LogRevision`` may now be None,
736
representing a revision which is not in the current branch.
737
(Matt Giuca, #241998)
739
* The various knit pack repository format classes have been moved
740
from ``bzrlib.repofmt.pack_repo`` to
741
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)
743
* ``RevisionTree`` now has a new method ``get_file_revision``.
746
* ``WorkingTree`` no longer provides an ``inventory``. Instead,
747
all inventory-related functionality is now on the subclass
748
``InventoryWorkingTree`` that all native Bazaar working tree
749
implementations derive from. (Jelmer Vernooij)
754
.. Major internal changes, unlikely to be visible to users or plugin
755
developers, but interesting for bzr developers.
757
* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
758
functions on Linux, but they are wrapped on Windows so that fstat
759
matches lstat results across all python versions.
762
* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
763
happened to be updated as a side-effect of commit, but if we start using
764
the function elsewhere we might as well do it directly.
770
.. Fixes and changes that are only relevant to bzr's test framework and
771
suite. This can include new facilities for writing tests, fixes to
772
spurious test failures and changes to the way things should be tested.
774
* Stop using `failIf`, `failUnless`, `failIfEqual`, etc, that give
775
`PendingDeprecationWarnings` on Python2.7.
776
(Martin Pool, #760435)
784
This is the first beta of the 2.4 series, leading up to a 2.4.0
785
release in August 2011. Beta releases are suitable for everyday use
786
but may cause some incompatibilities with plugins. Some plugins may need
787
small updates to work with 2.4b1.
789
External Compatibility Breaks
790
*****************************
797
* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
798
in GNU format. See ``bzr help changelog_merge`` for details.
801
* Configuration options can now use references to other options in the same
802
file by enclosing them with curly brackets (``{other_opt}``). This makes it
803
possible to use, for example,
804
``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
805
using a loom. During the beta period, the default behaviour is to disable
806
this feature. It can be activated by declaring ``bzr.config.expand = True``
807
in ``bazaar.conf``. (Vincent Ladeuil)
809
* External merge tools can now be configured in bazaar.conf. See
810
``bzr help configuration`` for more information. (Gordon Tyler, #489915)
812
* The ``lp:`` directory service now supports Launchpad's QA staging.
813
(Jelmer Vernooij, #667483)
818
* A new hidden command ``bzr repair-workingtree``. This is a way to force
819
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
820
workaround. (John Arbash Meinel)
822
* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
823
This allows formats from plugins (such as looms) to efficiently tell the
824
client which revisions need to be fetched. (Andrew Bennetts)
826
* Branching, merging and pulling a branch now copies revisions named in
827
tags, not just the tag metadata. (Andrew Bennetts, #309682)
829
* ``bzr cat-revision`` no longer requires a working tree.
830
(Jelmer Vernooij, #704405)
832
* ``bzr export --per-file-timestamps`` for .tar.gz files will now
833
override the mtime for trees exported on Python 2.7 and later, which
834
expose the 'mtime' field in gzip files. This makes the output of
835
``bzr export --per-file-timestamps`` for a particular tree
836
deterministic. (Jelmer Vernooij, #711226)
838
* ``bzr export --format=zip`` can now export to standard output,
839
like the other exporters can. (Jelmer Vernooij, #513752)
841
* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
842
(Jelmer Vernooij, #551714)
844
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
845
sped up dramatically for large trees. Iterating by dir is not the best
846
way to load data from a CHK inventory, so it preloads all the items in
847
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
848
of CHK data, down to just 150MB.) This has noticeable affects for things
849
like building checkouts, etc. (John Arbash Meinel, #737234)
854
* A MemoryError thrown on the server during a remote operation will now be
855
usefully reported, and other unexpected errors will include the class name.
856
(Martin [gz], #722416)
858
* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
859
(Andrew King, #537442)
861
* ``bzr export`` to zip files will now set a mode on directories.
862
(Jelmer Vernooij, #207253)
864
* ``bzr export`` to tgz files will only write out the basename of the
865
tarfile to the gzip file. (Jelmer Vernooij, #102234)
867
* ``bzr push --overwrite`` with an older revision specified will now correctly
868
roll back the target branch. (Jelmer Vernooij, #386576)
870
* ``bzr lp-propose`` can now propose merges against packaging branches on
871
Launchpad without requiring the target branch to be specified.
872
(Jelmer Vernooij, #704647)
874
* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
875
instead leave setting the reviewer up to Launchpad if it was not specified.
876
(Jelmer Vernooij, #583772)
878
* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
879
(Jelmer Vernooij, #213185)
881
* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
882
paths, however they may still print junk if not on a UTF-8 terminal.
883
(Martin [gz], #707954)
885
* ``bzr reconfigure --unstacked`` now copies revisions (and their
886
ancestors) named in tags into the unstacked repository, not just the
887
ancestry of the branch's tip. (Andrew Bennetts, #401646)
889
* ``bzr serve`` no longer crashes when a server_started hook is installed and
890
IPv6 support is available on the system. (Jelmer Vernooij, #293697)
892
* ``bzr status`` will not rewrite the dirstate file if it only has
893
'trivial' changes. (Currently limited to dir updates and newly-added
894
files changing state.) This saves a bit of time for regular operations.
895
eg. ``bzr status`` in a 100k tree takes 1.4s to compute the status, but 1s
896
to re-save the dirstate file. (John Arbash Meinel, #765881)
898
* ``bzr tags`` will no longer choke on branches with ghost revisions in
899
their mainline and tags on revisions not in the branch ancestry.
900
(Jelmer Vernooij, #397556)
902
* ``bzr whoami`` will now display an error if both a new identity and
903
``--email`` were specified. (Jelmer Vernooij, #680449)
905
* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
906
(Vincent Ladeuil, #706835)
908
* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
910
(Martin Pool, #586341)
912
* Plugins incompatible with the current version of bzr no longer produce a
913
warning on every command invocation. Instead, a message is shown by
914
``bzr plugins`` and in crash reports.
915
(#704195, Martin Pool)
917
* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
918
preserves the identity of default parameter values.
919
(Andrew Bennetts, #718569)
921
* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
922
containing no rows. (Eric Siegerman, #715508)
924
* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
925
without an explicit public location. (Max Bowsher)
927
* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
928
number of available processors. (Jelmer Vernooij, #693140)
933
* Added ``Branch.heads_to_fetch`` method. Implementations of the Branch API
934
must now inherit or implement this method. (Andrew Bennetts, #721328)
936
* Added ``bzrlib.mergetools`` module with helper functions for working with
937
the list of external merge tools. (Gordon Tyler, #489915)
939
* All methods and arguments that were deprecated before 2.0
940
have been removed. (Jelmer Vernooij)
942
* Branch formats should now be registered on the format registry
943
(``bzrlib.branch.format_registry``) rather than using the class
944
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)
946
* ``Branch.set_revision_history`` is now deprecated.
949
* ``BranchFormat.supports_leaving_lock()`` and
950
``RepositoryFormat.supports_leaving_lock`` flags have been added.
953
* ``Branch.fetch`` implementations must now accept an optional
954
``fetch_tags`` keyword argument. (Andrew Bennetts)
956
* ``Branch.import_last_revision_info`` is deprecated. Use the
957
``import_last_revision_info_and_tags`` method instead.
960
* Because it was too specific to BzrDir implementations,
961
``ControlDir.sprout`` no longer has a default implementation; it now
962
raises ``NotImplementedError``. (Jelmer Vernooij, #717937)
964
* ``bzrlib.deprecated_graph`` has been removed. ``bzrlib.graph``
965
scales better tree and should be used instead.
966
(Jelmer Vernooij, #733612)
968
* ``ControlDirFormat.register_format`` has been removed. Instead,
969
``Prober`` implementations should now implement a ``known_formats``
970
method. (Jelmer Vernooij)
972
* ControlDirFormats can now provide a ``check_status`` method and
973
raise a custom exception or warning when an unsupported or deprecated
974
format is being opened. (Jelmer Vernooij, #731311)
976
* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
977
Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
978
``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
979
instead. (Jelmer Vernooij, #721971)
981
* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
982
indicates whether the components of the bzrdir can be upgraded
983
independent of the ``BzrDir``. (Jelmer Vernooij)
985
* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
986
now deprecated in favour of the ``BzrProber.formats`` format registry.
989
* ``ControlDir`` implementations no longer have to provide the
990
``get_branch_transport``, ``get_workingtree_transport`` and
991
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)
993
* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
994
``bzrlib.controldir``. (Jelmer Vernooij)
996
* Repository formats can now provide
997
``_get_extra_interrepo_test_combinations`` in the same module
998
to provide extra test combinations for ``bzrlib.tests.per_repository``.
1001
* Repository formats should now be registered on the format registry
1002
(``bzrlib.repository.format_registry``) rather than using the class
1003
methods on ``RepositoryFormat``. (Jelmer Vernooij)
1005
* Repository formats can now indicate they do not support the full
1006
VersionedFiles API by setting the ``supports_full_versioned_files``
1007
attribute to False. A subset of the VersionedFiles API
1008
(signatures and text graphs) still needs to be supported.
1011
* Repository formats have a new method ``is_deprecated`` that
1012
implementations can override to return True to trigger a deprecation
1013
warning. (Jelmer Vernooij)
1015
* The ``revision_id`` parameter of
1016
``Repository.search_missing_revision_ids`` and
1017
``InterRepository.search_missing_revision_ids`` is deprecated. It is
1018
replaced by the ``revision_ids`` parameter. (Andrew Bennetts)
1020
* Working tree formats should now be registered on the format registry
1021
(``bzrlib.working_tree.format_registry``) rather than using the class
1022
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)
1024
* Exporting may now be done with a generator
1025
(``bzrlib.export.get_export_generator``) (Geoff/xaav, #791005)
1030
* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
1031
out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
1032
outside of tests. This class makes it easier to track exceptions in threads
1033
by catching them so they can be re-raised in the controlling thread. It's
1034
available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)
1036
* Correctly propogate malloc failures from diff-delta.c code as MemoryError
1037
so OOM conditions during groupcompress are clearly reported. This entailed a
1038
change to several function signatures. (Martin [gz], #633336)
1040
* ``HookPoint.lazy_hook`` and ``Hooks.install_named_lazy_hook`` can install
1041
hooks for which the callable is loaded lazily. (Jelmer Vernooij)
1046
* The Range parsing for HTTP requests will correctly parse incomplete ranges.
