*****************************
16
.. These may require users to change the way they use Bazaar.
21
.. New commands, options, etc that users may wish to try out.
23
* New command ``verify-signatures`` to check if all commits or specified commits
24
have digital signatures from trusted keys. Requires python-gpgme to be
27
* New option ``--signatures`` for ``bzr log`` to display digital signature
28
verification results for each commit.
30
* Config option acceptable_keys to list which GPG keys are verified as trusted.
32
* Config option validate_signatures_in_log to always show signatures in
38
.. Improvements to existing commands, especially improved performance
39
or memory usage, or better results.
41
* ``Branch.open`` is now about 3x faster (about 2ms instead of 6.5ms).
47
* Display a proper error message when a config file content cannot be
48
decoded as UTF-8 or when it cannot be parsed.
49
(Vincent Ladeuil, #502060, #688677, #792246)
51
* Generate a single conflict (instead of two) when merging a branch
52
modifying and renaming a file in a branch that deleted it (or vice-versa).
53
(Vincent Ladeuil, #688101)
55
* Properly load utf8-encoded config files. (Vincent Ladeuil, #799212)
57
* ``GraphThunkIdsToKeys.merge_sort`` now properly returns
58
keys rather than ids. (Jelmer Vernooij, #799677)
60
* ``TreeTransformBase.fixup_new_roots`` can now check that a tree root
61
is present. (Jelmer Vernooij, #801257)
63
.. Fixes for situations where bzr would previously crash or give incorrect
64
or undesirable results.
69
.. Improved or updated documentation.
74
.. Changes that may require updates in plugins or other code that uses
77
* New attributes ``WorkingTreeFormat.supports_versioned_directories`` and
78
``RepositoryFormat.supports_versioned_directories``.
79
(Jelmer Vernooij, #765815)
84
.. Major internal changes, unlikely to be visible to users or plugin
85
developers, but interesting for bzr developers.
87
* Start implementing localization, starting with command help text (but not
88
the command options themselves). This will allow bootstrapping the bzr
89
internationalization process. (Inada Naoki)
94
.. Fixes and changes that are only relevant to bzr's test framework and
95
suite. This can include new facilities for writing tests, fixes to
96
spurious test failures and changes to the way things should be tested.
98
* Fix test failures when running as a homeless user (debian buildd). Tests
99
leaking into ``${HOME}/.bzr.log`` should be detected properly now.

This is the fourth beta of the 2.4 series, leading to a 2.4.0 release in
108
August 2011. Beta releases are suitable for everyday use but may cause some
109
incompatibilities with plugins.

*****************************
118
.. These may require users to change the way they use Bazaar.
120
* Do not treat configuration option 'check_signatures = require' as if
121
it were 'create_signatures = always' (Jonathan Riddell)
126
.. New commands, options, etc that users may wish to try out.
128
* Hooks have been added for config stacks: ``get``, ``set`` and ``remove``
129
are called when an option is respectively read, modified or deleted. Also
130
added ``load`` and ``save`` hooks for config stores, called when the
131
stores are loaded or saved. (Vincent Ladeuil)
133
* New hook server_exception in bzrlib.smart.server to catch any
134
exception caused while running bzr serve.
135
(Jonathan Riddell, #274578)
138
* New hook set_commit_message in bzrlib.msgeditor to set a commit message
139
and revision properties. (Jonathan Riddell, #274578)
141
* Support ``-S`` as an alias for ``--short`` for the ``log`` and
142
``missing`` commands. (Martin von Gagern, #38655)
147
.. Improvements to existing commands, especially improved performance
148
or memory usage, or better results.
150
* ``bzr annotate`` can be run without setting whoami data first.
151
(Jonathan Riddell, #667408)
156
.. Fixes for situations where bzr would previously crash or give incorrect
157
or undesirable results.
159
* Bazaar can now detect when a lock file is held by a dead process
160
originating from the same machine, and steal the lock after printing a
161
message to the user. This is off by default, for safety, but can be
162
turned on by setting the configuration variable ``locks.steal_dead`` to
164
(Martin Pool, #220464)
166
* Credentials in the log output produced by ``-Dhttp`` are masked so users
167
can more freely post them in bug reports. (Vincent Ladeuil, #723074)
169
* Fix a race condition for ``server_started`` hooks leading to a spurious
170
test failure. (Vincent Ladeuil, #789167)
172
* Fix exporting subdirectory with ``--per-file-timestamps``.
173
(Szilveszter Farkas, #795557)
175
* Handle files that get created but don't get used during TreeTransform.
176
``open()`` can create a file, and still raise an exception before it
177
returns. So anything we might have created, make sure we destroy during
178
``finalize()``. (Martin [gz], #597686)
180
* ``pack_repo`` now uses ``Transport.move`` instead of
181
``Transport.rename``, deleting any existing targets even on SFTP.
182
(Martin von Gagern, #421776)
184
* Pass the ``build_mo`` command to the rest of the setup() calls in
185
setup.py. The ``bdist_wininst`` and ``py2exe`` code paths were failing
186
because ``build_mo`` became a required step that they didn't know about.
187
(John Arbash Meinel, #787122)
189
* Properly avoid re-adding a file after it changes case on CICP
190
filesystems. (John Arbash Meinel, #798130)
192
* Reports the original error when an InvalidHttpResponse exception is
193
encountered to facilitate debug. (Vincent Ladeuil, #788530)
195
* Reports a non-existant file error when trying to merge in a file
196
that does not exist. (Jonathan Riddell, #330063)
198
* ``UIFactory.prompt``, ``UIFactory.get_username``,
199
``UIFactory.get_password`` and ``UIFactory.get_boolean`` now require a
200
unicode prompt to be passed in. (Jelmer Vernooij, #592083)
202
* Support merging into the empty tree. (Aaron Bentley, #595328)
207
.. Improved or updated documentation.
209
* Improve documentation of ``bzr merge --force``.
210
(Neil Martinsen-Burrell, #767307)
212
* Make docs for configuration options for digital signatures match
213
reality. (Jonathan Riddell)
215
* Add user-guide page on GPG signatures. (Jonathan Riddell)
220
.. Changes that may require updates in plugins or other code that uses
223
* Checking for a file id in a `Tree` or `Inventory` using ``in`` is now
224
deprecated. Instead, use `has_id`.
227
* Exporters are now all exposed as generators, rather than as single-call
228
functions, so that calling code can take stream the output.
231
* Information about held lockdir locks returned from eg `LockDir.peek` is
232
now represented as a `LockHeldInfo` object, rather than a plain
236
* Remove `file_status` function.
239
* ``Repository.iter_reverse_revision_history`` is now deprecated.
240
Use ``Graph.iter_lefthand_ancestry`` instead.
241
(Jelmer Vernooij, #739481)
243
* ``Repository.get_ancestry`` has been deprecated. Use
244
``Graph.iter_ancestry`` instead.
245
(Jelmer Vernooij, #784511)
250
.. Major internal changes, unlikely to be visible to users or plugin
251
developers, but interesting for bzr developers.
253
* ``tools/check-newsbugs.py`` accepts a ``--browser`` option to open
254
corresponding launchpad pages in a browser. (Vincent Ladeuil)
259
.. Fixes and changes that are only relevant to bzr's test framework and
260
suite. This can include new facilities for writing tests, fixes to
261
spurious test failures and changes to the way things should be tested.
263
* A `ImportTariffTestCase` base class has been added in
264
``bzrlib.tests.test_import_tariff``, which can be used for import tariff
265
tests in plugins. (Jelmer Vernooij, #793465)
267
* Fix deadlock in `TestImportTariffs.test_simple_serve` when stderr gets
268
more output than fits in the default buffer. This was happening on the
269
Windows buildslave, and could easily happen in other circumstances where
270
the default OS buffer size for pipes is small or the ``python -v``
271
output is large. (Andrew Bennetts, #784802)
273
* Fix spurious test failure on OSX for WorkingTreeFormat2.
274
(Vincent Ladeuil, #787942)
276
* Re-target ``bb.test_merge.TestMerge.test_merge_reversed_revision_range``
277
and rewrite it as a parameterized test to avoid unrelated failures.
278
(Vincent Ladeuil, #795456)
280
* Show log file contents from subprocesses started by
281
`start_bzr_subprocess` in test failure details. This may help diagnose
282
strange hangs and failures involving subprocesses. (Andrew Bennetts)
284
* Skip ``utextwrap`` tests when ``sphinx`` breaks text_wrap by an hostile
285
monkeypatch to textwrap.TextWrapper.wordsep_re.
286
(Vincent Ladeuil, #785098)
288
* Multiple ``selftest --exclude`` options are now combined instead of
289
overriding each other. (Vincent Ladeuil, #746991)
291
* Restore some ``FTPTransport`` test coverage by allowing ``pyftpdlib
292
0.6.0`` to be used. Also restore ``medusa`` support while leaving it
293
disabled to make it easier to use if/when we can in the future.
294
(Vincent Ladeuil, #781140)
296
* `TestImportTariffs` no longer uses the real ``$HOME``. This prevents it
297
from polluting ``$HOME/.bzr.log`` or being accidentally influenced by
298
user configuration such as aliases. It still runs with all the user's
299
plugins enabled, as intended.
300
(Vincent Ladeuil, Andrew Bennetts, #789505)
308
This is the third beta of the 2.4 series, leading to a 2.4.0 release in
309
August 2011. Beta releases are suitable for everyday use but may cause some

incompatibilities with plugins.

317
*****************************
319
.. These may require users to change the way they use Bazaar.
321
* ``bzr-2.4`` has officially dropped support for python2.4 and python2.5.
322
We will continue to maintain ``bzr-2.3`` for people who still need to
323
use those versions of python. (John Arbash Meinel)
328
.. New commands, options, etc that users may wish to try out.
330
* The text compressor used for 2a repositories now has a tweakable
331
parameter that can be set in bazaar.conf.
332
``bzr.groupcompress.max_entries_per_source`` default of 65536.
333
When doing compression, we build up an index of locations to match
334
against. Setting this higher will result in slightly better compression,
335
at a cost of more memory. Note that a value of 65k represents fully
336
sampling a 1MB file. So this only has an effect when compressing texts
337
larger than N*16 bytes. (John Arbash Meinel, #602614)
342
.. Improvements to existing commands, especially improved performance
343
or memory usage, or better results.
345
* ``bzr branch --stacked`` from a smart server uses the network a little
346
more efficiently. For a simple branch it reduces the number of
347
round-trips by about 20%. (Andrew Bennetts)
349
* ``bzr log --line`` scales the width of the author field with the size of
350
the line. This means that the full author name is shown when the
351
environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)
353
* ``bzr pull`` now properly triggers the fast
354
``CHKInventory.iter_changes`` rather than the slow generic
355
inter-Inventory changes. It used to use a ``DirStateRevisionTree`` as
356
one of the source trees, which is faster when we have to read the whole
357
inventory anyway, but much slower when we can get just the delta out of
358
the repository. On a 70k record tree, this changes ``bzr pull`` from 28s
359
down to 17s. (John Arbash Meinel, #780677)
361
* Slightly reduced memory consumption when fetching into a 2a repository
362
by reusing existing caching a little better. (Andrew Bennetts)
364
* Speed up ``bzr status`` by a little bit when there are a couple of
365
modified files. We now track how many files we have seen that need
366
updating, and only rewrite the dirstate file if enough of them have
367
changed. The default is 10, and can be overridden by setting the branch
368
option "``bzr.workingtree.worth_saving_limit``".
369
(Ian Clatworthy, John Arbash Meinel, #380202)
371
* Speed up ``bzr uncommit``. Instead of resetting the dirstate from
372
scratch, use ``update_basis_by_delta``, computing the delta from the
373
repository. (John Arbash Meinel, #780544)
378
.. Fixes for situations where bzr would previously crash or give incorrect
379
or undesirable results.
381
* All Tree types can now be exported as tar.*, zip or directories.
384
* ``bzr merge --no-remember location`` never sets ``submit_branch``.
385
(Vincent Ladeuil, #782169)
387
* ``bzr pull --no-remember location`` never sets
388
``parent_location``. ``bzr push --no-remember location`` never
389
sets ``push_location``. ``bzr send --no-remember
390
submit_location public_location`` never sets ``submit_branch``
391
nor ``public_branch``. (Vincent Ladeuil)
393
* Conflicts involving non-ascii filenames are now properly reported rather
394
than failing with a UnicodeEncodeError. (Martin [GZ], #686161)
396
* Correct parent is now set when using 'switch -b' with bound branches.
397
(A. S. Budden, #513709)
399
* Fix `bzr plugins` regression in bzr 2.4 which resulted in a traceback
400
from writelines on ckj terminals. (Martin [GZ], #754082)
402
* ``WT.inventory`` and ``WT.iter_entries_by_dir()`` was not correctly
403
reporting subdirectories that were tree references (in formats that
404
supported them). (John Arbash Meinel, #764677)
406
* Merging into empty branches now gives an error as this is currently
407
not supported. (Jonathan Riddell, #242175)
409
* Do not show exception to user on pointless commit error.
410
(Jonathan Riddell #317357)
412
* ``WT.update_basis_by_delta`` no longer requires that the deltas match
413
the current WT state. This allows ``update_basis_by_delta`` to be used
414
by more commands than just commit. Updating with a delta allows us to
415
not load the whole inventory, which can take 10+s with large trees.
416
(Jonathan Riddell, John Arbash Meinel, #781168)
418
* ``bzr mv --after old_name new_name`` now works if "new_name" is newly
419
added. (Benoît Pierre)
425
.. Improved or updated documentation.
427
* Restore the workaround for option names including dots (--1.14) which was
428
disabled when we stopped listing --1.9 as a format.
429
(Vincent Ladeuil, #782289)
434
.. Changes that may require updates in plugins or other code that uses
437
* ``annotate_file`` has been deprecated in favor of
438
``annotate_file_revision_tree``. (Jelmer Vernooij, #775598)
440
* ``Branch.fetch`` now takes an optional ``limit`` argument.
441
(Andrew Bennetts, Jelmer Vernooij, #750175)
443
* ``Inter.get`` now raises ``NoCompatibleInter`` if there are no
444
compatible optimisers rather than an instance of the class it is called
445
on. (Jelmer Vernooij)
447
* ``Branch.push`` now takes a ``lossy`` argument.
448
``Branch.lossy_push`` has been removed.
451
* New method ``Repository.get_file_graph`` which can return the
452
per-file revision graph. (Jelmer Vernooij, #775578)
454
* The default implementation of ``Branch`` is now oriented to
455
storing the branch tip. Branch implementations which store the full
456
history should now subclass ``FullHistoryBzrBranch``.
457
``Branch._last_revision_info`` has been renamed to
458
``Branch._read_last_revision_info`` (Jelmer Vernooij)
460
* ``Tree.__iter__`` has been deprecated; use ``Tree.all_file_ids``
461
instead. (Jelmer Vernooij)
463
* ``Tree.get_symlink_target`` now takes an optional ``path``
464
argument. (Jelmer Vernooij)
469
.. Major internal changes, unlikely to be visible to users or plugin
470
developers, but interesting for bzr developers.
472
* ``MutableTree.smart_add`` now uses inventory deltas.
473
(Jelmer Vernooij, #146165)
475
* Removed ``bzrlib.branch._run_with_write_locked_target`` as
476
``bzrlib.cleanup`` provides the same functionality in a more general
477
way. (Andrew Bennetts)
482
.. Fixes and changes that are only relevant to bzr's test framework and
483
suite. This can include new facilities for writing tests, fixes to
484
spurious test failures and changes to the way things should be tested.
486
* A test that was expected to fail but passes instead now counts as a failure
487
catching up with new testtools and subunit handling. (Martin [GZ], #654474)
489
* Make it easier for plugins to reuse the per_workingtree scenarios by
490
restoring the wt_scenarios helper that was accidentally deleted.
491
(Vincent Ladeuil, #783472)
493
* Removed ``test_breakin`` tests that were excessively prone to hanging,
494
did not work on Wine, and partly already disabled.
495
(Martin Pool, #408814, #746985)
497
* Windows locations are different and should be tested accordingly.
498
(Vincent Ladeuil, #788131)

514
*****************************
516
.. These may require users to change the way they use Bazaar.
518
* Two command synonyms for ``bzr branch`` have been deprecated, to avoid
519
confusion and to allow the names to later be reused. The removed names
520
are: ``get`` and ``clone``. (Martin Pool, #506265)
525
.. New commands, options, etc that users may wish to try out.
527
* ``bzr commit`` now supports a ``--lossy`` argument that can be used
528
to discard any data that can not be natively represented when committing
529
to a foreign VCS. (Jelmer Vernooij, #587721)
534
.. Improvements to existing commands, especially improved performance
535
or memory usage, or better results.
537
* ``bzr merge`` in large trees is now significantly faster. On a 70k entry
538
tree, the time went from ~3min down to 30s. This also effects ``bzr pull``
539
and ``bzr update`` since they use the same merge logic to update the
540
WorkingTree. (John Arbash Meinel, #759091)
542
* ``bzr revert`` now properly uses ``bzr status``'s optimized
543
``iter_changes``. This can be a significant performance difference (33s
544
to 5s on large trees). (John Arbash Meinel, #759096)
546
* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
547
the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
548
being handed off to the remote server anyway (xmlrpc has been mapping
549
``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
550
than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
551
months now.) By doing it ourselves, we can cut out substantial startup
552
time. From Netherlands to London it was taking 368ms to do the XMLRPC
553
call as much as 2s from Sydney. You can test the local logic by using
554
``-Dlaunchpad``. (John Arbash Meinel, #397739)
556
* When building a new WorkingTree (such as during ``bzr co`` or
557
``bzr branch``) we now properly store the stat and hash of files that
558
are old enough. This saves a fair amount of time on the first
559
``bzr status`` (on a 500MB tree, it saves about 30+s).
560
(John Arbash Meinel, #740932)
566
.. Fixes for situations where bzr would previously crash or give incorrect
567
or undesirable results.
569
* Arguments that can't be decoded to unicode in the current posix locale give
570
a clearer error message without a traceback. (Martin [gz], #745712)
572
* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
573
mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
574
these default values aren't relied on very often so this probably
575
wasn't causing any trouble. (Andrew Bennetts)
577
* ``bzr log`` now works on revisions which are not in the current branch.
578
(Matt Giuca, #241998)
580
* Don't rewrite the dirstate file when non-interesting changes have
581
occurred. This can significantly improve 'bzr status' times when there
582
are only small changes to a large tree.
583
(Ian Clatworthy, John Arbash Meinel, #380202)
585
* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
587
* ``bzrlib.merge.Merge`` now calls ``iter_changes`` without
588
``include_unversioned=True``. This makes it significantly faster in many
589
cases, because it only looks at modified files, rather than building
590
information about all files. This can cause failures in other
591
TreeTransform code, because it had been expecting to know the names of
592
things which had not changed (such as parent directories). All cases we
593
know about so far have been fixed, but there may be fallout for edge
594
cases that we are missing. (John Arbash Meinel, #759091)
596
* ``SFTPTransport`` is more pro-active about closing file-handles. This
597
reduces the chance of having threads fail from async requests while
598
running the test suite. (John Arbash Meinel, #656170)
600
* Standalone bzr.exe installation on Windows: user can put additional python
601
libraries into ``site-packages`` subdirectory of the installation directory,
602
this might be required for "installing" extra dependencies for some plugins.
603
(Alexander Belchenko, #743256)
605
* ``transform.revert()`` has been updated to use
606
``wt.iter_changes(basis_tree)`` rather than
607
``basis_tree.iter_changes(wt)``. This allows the optimized code path to
608
kick in, improving ``bzr revert`` times significantly (33s to 4s on
609
large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)
611
* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
612
parameter. If supplied, when the transform is applied, it will then call
613
``self._tree._observed_sha1`` for those files. This lets us update the
614
hash-cache for content that we create, preventing us from re-reading the
615
content in the next ``bzr status``. (John Arbash Meinel, #740932)
620
* Added a section about using a shared SSH account on a server for bzr+ssh
621
access. (Russell Smith)
623
* The documentation now recommends using SSH rather than SFTP in the
624
tutorials and the examples, because that will generally be much faster
625
and better in cases where it can be used. SFTP is still available and
626
mentioned as an alternative. (Martin Pool, #636712)
631
.. Changes that may require updates in plugins or other code that uses
634
* ``Branch.update_revisions`` has been made private and should no
635
longer be used by external users. Use ``Branch.pull`` or ``Branch.push``
636
instead. (Jelmer Vernooij, #771765)
638
* Commands now have an `invoked_as` attribute, showing the name under
639
which they were called before alias expansion.
642
* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
645
* If you call `bzrlib.initialize` but forget to enter the resulting object
646
as a context manager, bzrlib will now be initialized anyhow.
647
(Previously simple programs calling bzrlib might find the library was
648
mysteriously silent.)
651
* Inventory-specific functionality has been split out of ``Tree`` into
652
a new ``InventoryTree`` class. Tree instances no longer
653
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
655
* Inventory-specific functionality has been split out of ``RevisionTree``
656
into a new ``InventoryRevisionTree`` class. RevisionTree instances no
657
longer necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
659
* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)
661
* ``revision_graph_can_have_wrong_parents`` is now an attribute
662
on ``RepositoryFormat`` rather than a method on ``Repository``.
665
* ``Testament`` now takes a ``tree`` rather than an
666
``inventory``. (Jelmer Vernooij, #762608)
668
* ``TestCase.failUnlessExists`` and ``failIfExists`` are deprecated in
669
favour of ``assertPathExists`` and ``assertPathDoesNotExist``
673
* The ``revno`` parameter of ``log.LogRevision`` may now be None,
674
representing a revision which is not in the current branch.
675
(Matt Giuca, #241998)
677
* The various knit pack repository format classes have been moved
678
from ``bzrlib.repofmt.pack_repo`` to
679
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)
681
* ``RevisionTree`` now has a new method ``get_file_revision``.
684
* ``WorkingTree`` no longer provides an ``inventory``. Instead,
685
all inventory-related functionality is now on the subclass
686
``InventoryWorkingTree`` that all native Bazaar working tree
687
implementations derive from. (Jelmer Vernooij)
692
.. Major internal changes, unlikely to be visible to users or plugin
693
developers, but interesting for bzr developers.
695
* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
696
functions on Linux, but they are wrapped on Windows so that fstat
697
matches lstat results across all python versions.
700
* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
701
happened to be updated as a side-effect of commit, but if we start using
702
the function elsewhere we might as well do it directly.
708
.. Fixes and changes that are only relevant to bzr's test framework and
709
suite. This can include new facilities for writing tests, fixes to
710
spurious test failures and changes to the way things should be tested.
712
* Stop using `failIf`, `failUnless`, `failIfEqual`, etc, that give
713
`PendingDeprecationWarnings` on Python2.7.
714
(Martin Pool, #760435)
722
This is the first beta of the 2.4 series, leading up to a 2.4.0
723
release in August 2011. Beta releases are suitable for everyday use
724
but may cause some incompatibilities with plugins. Some plugins may need
725
small updates to work with 2.4b1.
727
External Compatibility Breaks
728
*****************************
735
* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
736
in GNU format. See ``bzr help changelog_merge`` for details.
739
* Configuration options can now use references to other options in the same
740
file by enclosing them with curly brackets (``{other_opt}``). This makes it
741
possible to use, for example,
742
``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
743
using a loom. During the beta period, the default behaviour is to disable
744
this feature. It can be activated by declaring ``bzr.config.expand = True``
745
in ``bazaar.conf``. (Vincent Ladeuil)
747
* External merge tools can now be configured in bazaar.conf. See
748
``bzr help configuration`` for more information. (Gordon Tyler, #489915)
750
* The ``lp:`` directory service now supports Launchpad's QA staging.
751
(Jelmer Vernooij, #667483)
756
* A new hidden command ``bzr repair-workingtree``. This is a way to force
757
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
758
workaround. (John Arbash Meinel)
760
* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
761
This allows formats from plugins (such as looms) to efficiently tell the
762
client which revisions need to be fetched. (Andrew Bennetts)
764
* Branching, merging and pulling a branch now copies revisions named in
765
tags, not just the tag metadata. (Andrew Bennetts, #309682)
767
* ``bzr cat-revision`` no longer requires a working tree.
768
(Jelmer Vernooij, #704405)
770
* ``bzr export --per-file-timestamps`` for .tar.gz files will now
771
override the mtime for trees exported on Python 2.7 and later, which
772
expose the 'mtime' field in gzip files. This makes the output of
773
``bzr export --per-file-timestamps`` for a particular tree
774
deterministic. (Jelmer Vernooij, #711226)
776
* ``bzr export --format=zip`` can now export to standard output,
777
like the other exporters can. (Jelmer Vernooij, #513752)
779
* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
780
(Jelmer Vernooij, #551714)
782
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
783
sped up dramatically for large trees. Iterating by dir is not the best
784
way to load data from a CHK inventory, so it preloads all the items in
785
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
786
of CHK data, down to just 150MB.) This has noticeable affects for things
787
like building checkouts, etc. (John Arbash Meinel, #737234)
792
* A MemoryError thrown on the server during a remote operation will now be
793
usefully reported, and other unexpected errors will include the class name.
794
(Martin [gz], #722416)
796
* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
797
(Andrew King, #537442)
799
* ``bzr export`` to zip files will now set a mode on directories.
800
(Jelmer Vernooij, #207253)
802
* ``bzr export`` to tgz files will only write out the basename of the
803
tarfile to the gzip file. (Jelmer Vernooij, #102234)
805
* ``bzr push --overwrite`` with an older revision specified will now correctly
806
roll back the target branch. (Jelmer Vernooij, #386576)
808
* ``bzr lp-propose`` can now propose merges against packaging branches on
809
Launchpad without requiring the target branch to be specified.
810
(Jelmer Vernooij, #704647)
812
* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
813
instead leave setting the reviewer up to Launchpad if it was not specified.
814
(Jelmer Vernooij, #583772)
816
* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
817
(Jelmer Vernooij, #213185)
819
* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
820
paths, however they may still print junk if not on a UTF-8 terminal.
821
(Martin [gz], #707954)
823
* ``bzr reconfigure --unstacked`` now copies revisions (and their
824
ancestors) named in tags into the unstacked repository, not just the
825
ancestry of the branch's tip. (Andrew Bennetts, #401646)
827
* ``bzr serve`` no longer crashes when a server_started hook is installed and
828
IPv6 support is available on the system. (Jelmer Vernooij, #293697)
830
* ``bzr status`` will not rewrite the dirstate file if it only has
831
'trivial' changes. (Currently limited to dir updates and newly-added
832
files changing state.) This saves a bit of time for regular operations.
833
eg. ``bzr status`` in a 100k tree takes 1.4s to compute the status, but 1s
834
to re-save the dirstate file. (John Arbash Meinel, #765881)
836
* ``bzr tags`` will no longer choke on branches with ghost revisions in
837
their mainline and tags on revisions not in the branch ancestry.
838
(Jelmer Vernooij, #397556)
840
* ``bzr whoami`` will now display an error if both a new identity and
841
``--email`` were specified. (Jelmer Vernooij, #680449)
843
* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
844
(Vincent Ladeuil, #706835)
846
* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
848
(Martin Pool, #586341)
850
* Plugins incompatible with the current version of bzr no longer produce a
851
warning on every command invocation. Instead, a message is shown by
852
``bzr plugins`` and in crash reports.
853
(#704195, Martin Pool)
855
* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
856
preserves the identity of default parameter values.
857
(Andrew Bennetts, #718569)
859
* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
860
containing no rows. (Eric Siegerman, #715508)
862
* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
863
without an explicit public location. (Max Bowsher)
865
* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
866
number of available processors. (Jelmer Vernooij, #693140)
871
* Added ``Branch.heads_to_fetch`` method. Implementations of the Branch API
872
must now inherit or implement this method. (Andrew Bennetts, #721328)
874
* Added ``bzrlib.mergetools`` module with helper functions for working with
875
the list of external merge tools. (Gordon Tyler, #489915)
877
* All methods and arguments that were deprecated before 2.0
878
have been removed. (Jelmer Vernooij)
880
* Branch formats should now be registered on the format registry
881
(``bzrlib.branch.format_registry``) rather than using the class
882
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)
884
* ``Branch.set_revision_history`` is now deprecated.
887
* ``BranchFormat.supports_leaving_lock()`` and
888
``RepositoryFormat.supports_leaving_lock`` flags have been added.
891
* ``Branch.fetch`` implementations must now accept an optional
892
``fetch_tags`` keyword argument. (Andrew Bennetts)
894
* ``Branch.import_last_revision_info`` is deprecated. Use the
895
``import_last_revision_info_and_tags`` method instead.
898
* Because it was too specific to BzrDir implementations,
899
``ControlDir.sprout`` no longer has a default implementation; it now
900
raises ``NotImplementedError``. (Jelmer Vernooij, #717937)
902
* ``bzrlib.deprecated_graph`` has been removed. ``bzrlib.graph``
903
scales better tree and should be used instead.
904
(Jelmer Vernooij, #733612)
906
* ``ControlDirFormat.register_format`` has been removed. Instead,
907
``Prober`` implementations should now implement a ``known_formats``
908
method. (Jelmer Vernooij)
910
* ControlDirFormats can now provide a ``check_status`` method and
911
raise a custom exception or warning when an unsupported or deprecated
912
format is being opened. (Jelmer Vernooij, #731311)
914
* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
915
Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
916
``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
917
instead. (Jelmer Vernooij, #721971)
919
* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
920
indicates whether the components of the bzrdir can be upgraded
921
independent of the ``BzrDir``. (Jelmer Vernooij)
923
* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
924
now deprecated in favour of the ``BzrProber.formats`` format registry.
927
* ``ControlDir`` implementations no longer have to provide the
928
``get_branch_transport``, ``get_workingtree_transport`` and
929
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)
931
* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
932
``bzrlib.controldir``. (Jelmer Vernooij)
934
* Repository formats can now provide
935
``_get_extra_interrepo_test_combinations`` in the same module
936
to provide extra test combinations for ``bzrlib.tests.per_repository``.
939
* Repository formats should now be registered on the format registry
940
(``bzrlib.repository.format_registry``) rather than using the class
941
methods on ``RepositoryFormat``. (Jelmer Vernooij)
943
* Repository formats can now indicate they do not support the full
944
VersionedFiles API by setting the ``supports_full_versioned_files``
945
attribute to False. A subset of the VersionedFiles API
946
(signatures and text graphs) still needs to be supported.
949
* Repository formats have a new method ``is_deprecated`` that
950
implementations can override to return True to trigger a deprecation
951
warning. (Jelmer Vernooij)
953
* The ``revision_id`` parameter of
954
``Repository.search_missing_revision_ids`` and
955
``InterRepository.search_missing_revision_ids`` is deprecated. It is
956
replaced by the ``revision_ids`` parameter. (Andrew Bennetts)
958
* Working tree formats should now be registered on the format registry
959
(``bzrlib.working_tree.format_registry``) rather than using the class
960
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)
962
* Exporting may now be done with a generator
963
(``bzrlib.export.get_export_generator``) (Geoff/xaav, #791005)
968
* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
969
out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
970
outside of tests. This class makes it easier to track exceptions in threads
971
by catching them so they can be re-raised in the controlling thread. It's
972
available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)
974
* Correctly propogate malloc failures from diff-delta.c code as MemoryError
975
so OOM conditions during groupcompress are clearly reported. This entailed a
976
change to several function signatures. (Martin [gz], #633336)
978
* ``HookPoint.lazy_hook`` and ``Hooks.install_named_lazy_hook`` can install
979
hooks for which the callable is loaded lazily. (Jelmer Vernooij)
984
* The Range parsing for HTTP requests will correctly parse incomplete ranges.
