*****************************
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.
35
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
36
checks to see if the most recent published source package version for
37
that project is present in the branch tags. This should help developers
38
trust whether the packaging branch is up-to-date and can be used for new
39
changes. The level of verbosity is controlled by the config item
40
``launchpad.packaging_verbosity``. It can be set to one of
47
only display if the branch is out-of-date
50
also display single-line up-to-date and missing,
54
(default) display multi-line content for all states
57
(John Arbash Meinel, #609187, #812928)
60
* The fix for bug #513709 caused us to open a new connection when
61
switching a lightweight checkout that was pointing at a bound branch.
62
This isn't necessary because we know the master URL without opening it,
63
avoiding an extra SSH connection, etc.
64
(John Arbash Meinel, #812285)
69
.. Improved or updated documentation.
74
.. Changes that may require updates in plugins or other code that uses
80
.. Major internal changes, unlikely to be visible to users or plugin
81
developers, but interesting for bzr developers.
86
.. Fixes and changes that are only relevant to bzr's test framework and
87
suite. This can include new facilities for writing tests, fixes to
88
spurious test failures and changes to the way things should be tested.
90
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
91
cleanly and reliably allows tests using `BranchBuilder` to construct
92
branches that e.g. rename files out of a directory and unversion that
93
directory in the same revision. Previously some changes were impossible
94
due to the order that `build_snapshot` performs its actions.
97
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
98
just compares the bytes in the dirstate file to its pristine state,
99
rather than opening the WorkingTree and calling ``last_revision()``.
100
This reduces the overall test suite time by about 10% on my laptop.
109
This is the fifth (and last) beta of the 2.4 series leading to
110
2.4.0 release in Auguest 2011. Beta releases are suitable for
111
everyday use but may cause some incompatibilities with plugins.
113
This release includes all bug fixed in previous series known at
114
the time of this release.

*****************************
124
* New command ``verify-signatures`` to check if all commits or specified commits
125
have digital signatures from trusted keys. Requires python-gpgme to be
128
* New option ``--signatures`` for ``bzr log`` to display digital signature
129
verification results for each commit.
131
* Config option acceptable_keys to list which GPG keys are verified as trusted.
133
* Config option validate_signatures_in_log to always show signatures in
139
* ``Branch.open`` is now about 3x faster (about 2ms instead of 6.5ms).
142
* Pack, dirstate, and index files are synced to persistent storage if
143
possible when writing finishes, to reduce the risk of problems caused by
144
a machine crash or similar problem. This can be turned off through the
145
``dirstate.fdatasync`` and ``repository.fdatasync`` options, which can
146
be set in ``locations.conf`` or ``bazaar.conf``. (Martin Pool,
152
* Display a proper error message when a config file content cannot be
153
decoded as UTF-8 or when it cannot be parsed.
154
(Vincent Ladeuil, #502060, #688677, #797246)
156
* Generate a single conflict (instead of two) when merging a branch
157
modifying and renaming a file in a branch that deleted it (or vice-versa).
158
(Vincent Ladeuil, #688101)
160
* Give a more helpful message when the bzr executable doesn't match the
161
library. (This typically happens because of a misconfigured PYTHONPATH
162
or half-installed bzr.)
163
(Martin Pool, #804553)
165
* Properly load utf8-encoded config files. (Vincent Ladeuil, #799212)
167
* ``GraphThunkIdsToKeys.merge_sort`` now properly returns
168
keys rather than ids. (Jelmer Vernooij, #799677)
170
* ``TreeTransformBase.fixup_new_roots`` can now check that a tree root
171
is present. (Jelmer Vernooij, #801257)
176
* New attributes ``WorkingTreeFormat.supports_versioned_directories`` and
177
``RepositoryFormat.supports_versioned_directories``.
178
(Jelmer Vernooij, #765815)
180
* The "revno" field type when using the python version-info format is now
181
a string (to handle dotted revnos) (Benoît Pierre, #796259)
186
* Start implementing localization, starting with command help text (but not
187
the command options themselves). This will allow bootstrapping the bzr
188
internationalization process. (Inada Naoki)
193
* Fix test failures when running as a homeless user (debian buildd). Tests
194
leaking into ``${HOME}/.bzr.log`` should be detected properly now.
195

*****************************
213
.. These may require users to change the way they use Bazaar.
215
* Do not treat configuration option 'check_signatures = require' as if
216
it were 'create_signatures = always' (Jonathan Riddell)
221
.. New commands, options, etc that users may wish to try out.
223
* Hooks have been added for config stacks: ``get``, ``set`` and ``remove``
224
are called when an option is respectively read, modified or deleted. Also
225
added ``load`` and ``save`` hooks for config stores, called when the
226
stores are loaded or saved. (Vincent Ladeuil)
228
* New hook server_exception in bzrlib.smart.server to catch any
229
exception caused while running bzr serve.
230
(Jonathan Riddell, #274578)
232
* New hook set_commit_message in bzrlib.msgeditor to set a commit message
233
and revision properties. (Jonathan Riddell, #274578)
235
* Support ``-S`` as an alias for ``--short`` for the ``log`` and
236
``missing`` commands. (Martin von Gagern, #38655)
241
.. Improvements to existing commands, especially improved performance
242
or memory usage, or better results.
244
* ``bzr annotate`` can be run without setting whoami data first.
245
(Jonathan Riddell, #667408)
250
.. Fixes for situations where bzr would previously crash or give incorrect
251
or undesirable results.
253
* Bazaar can now detect when a lock file is held by a dead process
254
originating from the same machine, and steal the lock after printing a
255
message to the user. This is off by default, for safety, but can be
256
turned on by setting the configuration variable ``locks.steal_dead`` to
258
(Martin Pool, #220464)
260
* ``bzr version-info`` now works when the tree is on a dotted revno.
261
(Benoît Pierre, #796259)
263
* Credentials in the log output produced by ``-Dhttp`` are masked so users
264
can more freely post them in bug reports. (Vincent Ladeuil, #723074)
266
* Fix a race condition for ``server_started`` hooks leading to a spurious
267
test failure. (Vincent Ladeuil, #789167)
269
* Fix exporting subdirectory with ``--per-file-timestamps``.
270
(Szilveszter Farkas, #795557)
272
* Handle files that get created but don't get used during TreeTransform.
273
``open()`` can create a file, and still raise an exception before it
274
returns. So anything we might have created, make sure we destroy during
275
``finalize()``. (Martin [gz], #597686)
277
* ``pack_repo`` now uses ``Transport.move`` instead of
278
``Transport.rename``, deleting any existing targets even on SFTP.
279
(Martin von Gagern, #421776)
281
* Pass the ``build_mo`` command to the rest of the setup() calls in
282
setup.py. The ``bdist_wininst`` and ``py2exe`` code paths were failing
283
because ``build_mo`` became a required step that they didn't know about.
284
(John Arbash Meinel, #787122)
286
* Preserve existing ``root-id`` when merging an unrelated branch.
287
(Aaron Bentley, #806356)
289
* Properly avoid re-adding a file after it changes case on CICP
290
filesystems. (John Arbash Meinel, #798130)
292
* Reports the original error when an InvalidHttpResponse exception is
293
encountered to facilitate debug. (Vincent Ladeuil, #788530)
295
* Reports a non-existant file error when trying to merge in a file
296
that does not exist. (Jonathan Riddell, #330063)
298
* ``UIFactory.prompt``, ``UIFactory.get_username``,
299
``UIFactory.get_password`` and ``UIFactory.get_boolean`` now require a
300
unicode prompt to be passed in. (Jelmer Vernooij, #592083)
302
* Support merging into the empty tree. (Aaron Bentley, #595328)
307
.. Improved or updated documentation.
309
* Improve documentation of ``bzr merge --force``.
310
(Neil Martinsen-Burrell, #767307)
312
* Make docs for configuration options for digital signatures match
313
reality. (Jonathan Riddell)
315
* Add user-guide page on GPG signatures. (Jonathan Riddell)
320
.. Changes that may require updates in plugins or other code that uses
323
* Checking for a file id in a `Tree` or `Inventory` using ``in`` is now
324
deprecated. Instead, use `has_id`.
327
* Exporters are now all exposed as generators, rather than as single-call
328
functions, so that calling code can take stream the output.
331
* Information about held lockdir locks returned from eg `LockDir.peek` is
332
now represented as a `LockHeldInfo` object, rather than a plain
336
* Remove `file_status` function.
339
* ``Repository.iter_reverse_revision_history`` is now deprecated.
340
Use ``Graph.iter_lefthand_ancestry`` instead.
341
(Jelmer Vernooij, #739481)
343
* ``Repository.get_ancestry`` has been deprecated. Use
344
``Graph.iter_ancestry`` instead.
345
(Jelmer Vernooij, #784511)
350
.. Major internal changes, unlikely to be visible to users or plugin
351
developers, but interesting for bzr developers.
353
* ``tools/check-newsbugs.py`` accepts a ``--browser`` option to open
354
corresponding launchpad pages in a browser. (Vincent Ladeuil)
359
.. Fixes and changes that are only relevant to bzr's test framework and
360
suite. This can include new facilities for writing tests, fixes to
361
spurious test failures and changes to the way things should be tested.
363
* A `ImportTariffTestCase` base class has been added in
364
``bzrlib.tests.test_import_tariff``, which can be used for import tariff
365
tests in plugins. (Jelmer Vernooij, #793465)
367
* Fix deadlock in `TestImportTariffs.test_simple_serve` when stderr gets
368
more output than fits in the default buffer. This was happening on the
369
Windows buildslave, and could easily happen in other circumstances where
370
the default OS buffer size for pipes is small or the ``python -v``
371
output is large. (Andrew Bennetts, #784802)
373
* Fix spurious test failure on OSX for WorkingTreeFormat2.
374
(Vincent Ladeuil, #787942)
376
* Re-target ``bb.test_merge.TestMerge.test_merge_reversed_revision_range``
377
and rewrite it as a parameterized test to avoid unrelated failures.
378
(Vincent Ladeuil, #795456)
380
* Show log file contents from subprocesses started by
381
`start_bzr_subprocess` in test failure details. This may help diagnose
382
strange hangs and failures involving subprocesses. (Andrew Bennetts)
384
* Skip ``utextwrap`` tests when ``sphinx`` breaks text_wrap by an hostile
385
monkeypatch to textwrap.TextWrapper.wordsep_re.
386
(Vincent Ladeuil, #785098)
388
* Multiple ``selftest --exclude`` options are now combined instead of
389
overriding each other. (Vincent Ladeuil, #746991)
391
* Restore some ``FTPTransport`` test coverage by allowing ``pyftpdlib
392
0.6.0`` to be used. Also restore ``medusa`` support while leaving it
393
disabled to make it easier to use if/when we can in the future.
394
(Vincent Ladeuil, #781140)
396
* `TestImportTariffs` no longer uses the real ``$HOME``. This prevents it
397
from polluting ``$HOME/.bzr.log`` or being accidentally influenced by
398
user configuration such as aliases. It still runs with all the user's
399
plugins enabled, as intended.

*****************************
419
.. These may require users to change the way they use Bazaar.
421
* ``bzr-2.4`` has officially dropped support for python2.4 and python2.5.
422
We will continue to maintain ``bzr-2.3`` for people who still need to
423
use those versions of python. (John Arbash Meinel)
428
.. New commands, options, etc that users may wish to try out.
430
* The text compressor used for 2a repositories now has a tweakable
431
parameter that can be set in bazaar.conf.
432
``bzr.groupcompress.max_entries_per_source`` default of 65536.
433
When doing compression, we build up an index of locations to match
434
against. Setting this higher will result in slightly better compression,
435
at a cost of more memory. Note that a value of 65k represents fully
436
sampling a 1MB file. So this only has an effect when compressing texts
437
larger than N*16 bytes. (John Arbash Meinel, #602614)
442
.. Improvements to existing commands, especially improved performance
443
or memory usage, or better results.
445
* ``bzr branch --stacked`` from a smart server uses the network a little
446
more efficiently. For a simple branch it reduces the number of
447
round-trips by about 20%. (Andrew Bennetts)
449
* ``bzr log --line`` scales the width of the author field with the size of
450
the line. This means that the full author name is shown when the
451
environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)
453
* ``bzr pull`` now properly triggers the fast
454
``CHKInventory.iter_changes`` rather than the slow generic
455
inter-Inventory changes. It used to use a ``DirStateRevisionTree`` as
456
one of the source trees, which is faster when we have to read the whole
457
inventory anyway, but much slower when we can get just the delta out of
458
the repository. On a 70k record tree, this changes ``bzr pull`` from 28s
459
down to 17s. (John Arbash Meinel, #780677)
461
* Slightly reduced memory consumption when fetching into a 2a repository
462
by reusing existing caching a little better. (Andrew Bennetts)
464
* Speed up ``bzr status`` by a little bit when there are a couple of
465
modified files. We now track how many files we have seen that need
466
updating, and only rewrite the dirstate file if enough of them have
467
changed. The default is 10, and can be overridden by setting the branch
468
option "``bzr.workingtree.worth_saving_limit``".
469
(Ian Clatworthy, John Arbash Meinel, #380202)
471
* Speed up ``bzr uncommit``. Instead of resetting the dirstate from
472
scratch, use ``update_basis_by_delta``, computing the delta from the
473
repository. (John Arbash Meinel, #780544)
478
.. Fixes for situations where bzr would previously crash or give incorrect
479
or undesirable results.
481
* All Tree types can now be exported as tar.*, zip or directories.
484
* ``bzr merge --no-remember location`` never sets ``submit_branch``.
485
(Vincent Ladeuil, #782169)
487
* ``bzr pull --no-remember location`` never sets
488
``parent_location``. ``bzr push --no-remember location`` never
489
sets ``push_location``. ``bzr send --no-remember
490
submit_location public_location`` never sets ``submit_branch``
491
nor ``public_branch``. (Vincent Ladeuil)
493
* Conflicts involving non-ascii filenames are now properly reported rather
494
than failing with a UnicodeEncodeError. (Martin [GZ], #686161)
496
* Correct parent is now set when using 'switch -b' with bound branches.
497
(A. S. Budden, #513709)
499
* Fix `bzr plugins` regression in bzr 2.4 which resulted in a traceback
500
from writelines on ckj terminals. (Martin [GZ], #754082)
502
* ``WT.inventory`` and ``WT.iter_entries_by_dir()`` was not correctly
503
reporting subdirectories that were tree references (in formats that
504
supported them). (John Arbash Meinel, #764677)
506
* Merging into empty branches now gives an error as this is currently
507
not supported. (Jonathan Riddell, #242175)
509
* Do not show exception to user on pointless commit error.
510
(Jonathan Riddell #317357)
512
* ``WT.update_basis_by_delta`` no longer requires that the deltas match
513
the current WT state. This allows ``update_basis_by_delta`` to be used
514
by more commands than just commit. Updating with a delta allows us to
515
not load the whole inventory, which can take 10+s with large trees.
516
(Jonathan Riddell, John Arbash Meinel, #781168)
518
* ``bzr mv --after old_name new_name`` now works if "new_name" is newly
519
added. (Benoît Pierre)
525
.. Improved or updated documentation.
527
* Restore the workaround for option names including dots (--1.14) which was
528
disabled when we stopped listing --1.9 as a format.
529
(Vincent Ladeuil, #782289)
534
.. Changes that may require updates in plugins or other code that uses
537
* ``annotate_file`` has been deprecated in favor of
538
``annotate_file_revision_tree``. (Jelmer Vernooij, #775598)
540
* ``Branch.fetch`` now takes an optional ``limit`` argument.
541
(Andrew Bennetts, Jelmer Vernooij, #750175)
543
* ``Inter.get`` now raises ``NoCompatibleInter`` if there are no
544
compatible optimisers rather than an instance of the class it is called
545
on. (Jelmer Vernooij)
547
* ``Branch.push`` now takes a ``lossy`` argument.
548
``Branch.lossy_push`` has been removed.
551
* New method ``Repository.get_file_graph`` which can return the
552
per-file revision graph. (Jelmer Vernooij, #775578)
554
* The default implementation of ``Branch`` is now oriented to
555
storing the branch tip. Branch implementations which store the full
556
history should now subclass ``FullHistoryBzrBranch``.
557
``Branch._last_revision_info`` has been renamed to
558
``Branch._read_last_revision_info`` (Jelmer Vernooij)
560
* ``Tree.__iter__`` has been deprecated; use ``Tree.all_file_ids``
561
instead. (Jelmer Vernooij)
563
* ``Tree.get_symlink_target`` now takes an optional ``path``
564
argument. (Jelmer Vernooij)
569
.. Major internal changes, unlikely to be visible to users or plugin
570
developers, but interesting for bzr developers.
572
* ``MutableTree.smart_add`` now uses inventory deltas.
573
(Jelmer Vernooij, #146165)
575
* Removed ``bzrlib.branch._run_with_write_locked_target`` as
576
``bzrlib.cleanup`` provides the same functionality in a more general
577
way. (Andrew Bennetts)
582
.. Fixes and changes that are only relevant to bzr's test framework and
583
suite. This can include new facilities for writing tests, fixes to
584
spurious test failures and changes to the way things should be tested.
586
* A test that was expected to fail but passes instead now counts as a failure
587
catching up with new testtools and subunit handling. (Martin [GZ], #654474)
589
* Make it easier for plugins to reuse the per_workingtree scenarios by
590
restoring the wt_scenarios helper that was accidentally deleted.
591
(Vincent Ladeuil, #783472)
593
* Removed ``test_breakin`` tests that were excessively prone to hanging,
594
did not work on Wine, and partly already disabled.
595
(Martin Pool, #408814, #746985)
597
* Windows locations are different and should be tested accordingly.

*****************************
616
.. These may require users to change the way they use Bazaar.
618
* Two command synonyms for ``bzr branch`` have been deprecated, to avoid
619
confusion and to allow the names to later be reused. The removed names
620
are: ``get`` and ``clone``. (Martin Pool, #506265)
625
.. New commands, options, etc that users may wish to try out.
627
* ``bzr commit`` now supports a ``--lossy`` argument that can be used
628
to discard any data that can not be natively represented when committing
629
to a foreign VCS. (Jelmer Vernooij, #587721)
634
.. Improvements to existing commands, especially improved performance
635
or memory usage, or better results.
637
* ``bzr merge`` in large trees is now significantly faster. On a 70k entry
638
tree, the time went from ~3min down to 30s. This also effects ``bzr pull``
639
and ``bzr update`` since they use the same merge logic to update the
640
WorkingTree. (John Arbash Meinel, #759091)
642
* ``bzr revert`` now properly uses ``bzr status``'s optimized
643
``iter_changes``. This can be a significant performance difference (33s
644
to 5s on large trees). (John Arbash Meinel, #759096)
646
* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
647
the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
648
being handed off to the remote server anyway (xmlrpc has been mapping
649
``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
650
than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
651
months now.) By doing it ourselves, we can cut out substantial startup
652
time. From Netherlands to London it was taking 368ms to do the XMLRPC
653
call as much as 2s from Sydney. You can test the local logic by using
654
``-Dlaunchpad``. (John Arbash Meinel, #397739)
656
* When building a new WorkingTree (such as during ``bzr co`` or
657
``bzr branch``) we now properly store the stat and hash of files that
658
are old enough. This saves a fair amount of time on the first
659
``bzr status`` (on a 500MB tree, it saves about 30+s).
660
(John Arbash Meinel, #740932)
666
.. Fixes for situations where bzr would previously crash or give incorrect
667
or undesirable results.
669
* Arguments that can't be decoded to unicode in the current posix locale give
670
a clearer error message without a traceback. (Martin [gz], #745712)
672
* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
673
mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
674
these default values aren't relied on very often so this probably
675
wasn't causing any trouble. (Andrew Bennetts)
677
* ``bzr log`` now works on revisions which are not in the current branch.
678
(Matt Giuca, #241998)
680
* Don't rewrite the dirstate file when non-interesting changes have
681
occurred. This can significantly improve 'bzr status' times when there
682
are only small changes to a large tree.
683
(Ian Clatworthy, John Arbash Meinel, #380202)
685
* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
687
* ``bzrlib.merge.Merge`` now calls ``iter_changes`` without
688
``include_unversioned=True``. This makes it significantly faster in many
689
cases, because it only looks at modified files, rather than building
690
information about all files. This can cause failures in other
691
TreeTransform code, because it had been expecting to know the names of
692
things which had not changed (such as parent directories). All cases we
693
know about so far have been fixed, but there may be fallout for edge
694
cases that we are missing. (John Arbash Meinel, #759091)
696
* ``SFTPTransport`` is more pro-active about closing file-handles. This
697
reduces the chance of having threads fail from async requests while
698
running the test suite. (John Arbash Meinel, #656170)
700
* Standalone bzr.exe installation on Windows: user can put additional python
701
libraries into ``site-packages`` subdirectory of the installation directory,
702
this might be required for "installing" extra dependencies for some plugins.
703
(Alexander Belchenko, #743256)
705
* ``transform.revert()`` has been updated to use
706
``wt.iter_changes(basis_tree)`` rather than
707
``basis_tree.iter_changes(wt)``. This allows the optimized code path to
708
kick in, improving ``bzr revert`` times significantly (33s to 4s on
709
large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)
711
* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
712
parameter. If supplied, when the transform is applied, it will then call
713
``self._tree._observed_sha1`` for those files. This lets us update the
714
hash-cache for content that we create, preventing us from re-reading the
715
content in the next ``bzr status``. (John Arbash Meinel, #740932)
720
* Added a section about using a shared SSH account on a server for bzr+ssh
721
access. (Russell Smith)
723
* The documentation now recommends using SSH rather than SFTP in the
724
tutorials and the examples, because that will generally be much faster
725
and better in cases where it can be used. SFTP is still available and
726
mentioned as an alternative. (Martin Pool, #636712)
731
.. Changes that may require updates in plugins or other code that uses
734
* ``Branch.update_revisions`` has been made private and should no
735
longer be used by external users. Use ``Branch.pull`` or ``Branch.push``
736
instead. (Jelmer Vernooij, #771765)
738
* Commands now have an `invoked_as` attribute, showing the name under
739
which they were called before alias expansion.
742
* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
745
* If you call `bzrlib.initialize` but forget to enter the resulting object
746
as a context manager, bzrlib will now be initialized anyhow.
747
(Previously simple programs calling bzrlib might find the library was
748
mysteriously silent.)
751
* Inventory-specific functionality has been split out of ``Tree`` into
752
a new ``InventoryTree`` class. Tree instances no longer
753
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
755
* Inventory-specific functionality has been split out of ``RevisionTree``
756
into a new ``InventoryRevisionTree`` class. RevisionTree instances no
757
longer necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
759
* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)
761
* ``revision_graph_can_have_wrong_parents`` is now an attribute
762
on ``RepositoryFormat`` rather than a method on ``Repository``.
765
* ``Testament`` now takes a ``tree`` rather than an
766
``inventory``. (Jelmer Vernooij, #762608)
768
* ``TestCase.failUnlessExists`` and ``failIfExists`` are deprecated in
769
favour of ``assertPathExists`` and ``assertPathDoesNotExist``
773
* The ``revno`` parameter of ``log.LogRevision`` may now be None,
774
representing a revision which is not in the current branch.
775
(Matt Giuca, #241998)
777
* The various knit pack repository format classes have been moved
778
from ``bzrlib.repofmt.pack_repo`` to
779
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)
781
* ``RevisionTree`` now has a new method ``get_file_revision``.
784
* ``WorkingTree`` no longer provides an ``inventory``. Instead,
785
all inventory-related functionality is now on the subclass
786
``InventoryWorkingTree`` that all native Bazaar working tree
787
implementations derive from. (Jelmer Vernooij)
792
.. Major internal changes, unlikely to be visible to users or plugin
793
developers, but interesting for bzr developers.
795
* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
796
functions on Linux, but they are wrapped on Windows so that fstat
797
matches lstat results across all python versions.
800
* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
801
happened to be updated as a side-effect of commit, but if we start using
802
the function elsewhere we might as well do it directly.
808
.. Fixes and changes that are only relevant to bzr's test framework and
809
suite. This can include new facilities for writing tests, fixes to
810
spurious test failures and changes to the way things should be tested.
812
* Stop using `failIf`, `failUnless`, `failIfEqual`, etc, that give
813
`PendingDeprecationWarnings` on Python2.7.
814
(Martin Pool, #760435)
822
This is the first beta of the 2.4 series, leading up to a 2.4.0
823
release in August 2011. Beta releases are suitable for everyday use
824
but may cause some incompatibilities with plugins. Some plugins may need
825
small updates to work with 2.4b1.
827
External Compatibility Breaks
828
*****************************
835
* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
836
in GNU format. See ``bzr help changelog_merge`` for details.
839
* Configuration options can now use references to other options in the same
840
file by enclosing them with curly brackets (``{other_opt}``). This makes it
841
possible to use, for example,
842
``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
843
using a loom. During the beta period, the default behaviour is to disable
844
this feature. It can be activated by declaring ``bzr.config.expand = True``
845
in ``bazaar.conf``. (Vincent Ladeuil)
847
* External merge tools can now be configured in bazaar.conf. See
848
``bzr help configuration`` for more information. (Gordon Tyler, #489915)
850
* The ``lp:`` directory service now supports Launchpad's QA staging.
851
(Jelmer Vernooij, #667483)
856
* A new hidden command ``bzr repair-workingtree``. This is a way to force
857
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
858
workaround. (John Arbash Meinel)
860
* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
861
This allows formats from plugins (such as looms) to efficiently tell the
862
client which revisions need to be fetched. (Andrew Bennetts)
864
* Branching, merging and pulling a branch now copies revisions named in
865
tags, not just the tag metadata. (Andrew Bennetts, #309682)
867
* ``bzr cat-revision`` no longer requires a working tree.
868
(Jelmer Vernooij, #704405)
870
* ``bzr export --per-file-timestamps`` for .tar.gz files will now
871
override the mtime for trees exported on Python 2.7 and later, which
872
expose the 'mtime' field in gzip files. This makes the output of
873
``bzr export --per-file-timestamps`` for a particular tree
874
deterministic. (Jelmer Vernooij, #711226)
876
* ``bzr export --format=zip`` can now export to standard output,
877
like the other exporters can. (Jelmer Vernooij, #513752)
879
* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
880
(Jelmer Vernooij, #551714)
882
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
883
sped up dramatically for large trees. Iterating by dir is not the best
884
way to load data from a CHK inventory, so it preloads all the items in
885
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
886
of CHK data, down to just 150MB.) This has noticeable affects for things
887
like building checkouts, etc. (John Arbash Meinel, #737234)
892
* A MemoryError thrown on the server during a remote operation will now be
893
usefully reported, and other unexpected errors will include the class name.
894
(Martin [gz], #722416)
896
* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
897
(Andrew King, #537442)
899
* ``bzr export`` to zip files will now set a mode on directories.
900
(Jelmer Vernooij, #207253)
902
* ``bzr export`` to tgz files will only write out the basename of the
903
tarfile to the gzip file. (Jelmer Vernooij, #102234)
905
* ``bzr push --overwrite`` with an older revision specified will now correctly
906
roll back the target branch. (Jelmer Vernooij, #386576)
908
* ``bzr lp-propose`` can now propose merges against packaging branches on
909
Launchpad without requiring the target branch to be specified.
910
(Jelmer Vernooij, #704647)
912
* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
913
instead leave setting the reviewer up to Launchpad if it was not specified.
914
(Jelmer Vernooij, #583772)
916
* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
917
(Jelmer Vernooij, #213185)
919
* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
920
paths, however they may still print junk if not on a UTF-8 terminal.
921
(Martin [gz], #707954)
923
* ``bzr reconfigure --unstacked`` now copies revisions (and their
924
ancestors) named in tags into the unstacked repository, not just the
925
ancestry of the branch's tip. (Andrew Bennetts, #401646)
927
* ``bzr serve`` no longer crashes when a server_started hook is installed and
928
IPv6 support is available on the system. (Jelmer Vernooij, #293697)
930
* ``bzr status`` will not rewrite the dirstate file if it only has
931
'trivial' changes. (Currently limited to dir updates and newly-added
932
files changing state.) This saves a bit of time for regular operations.
933
eg. ``bzr status`` in a 100k tree takes 1.4s to compute the status, but 1s
934
to re-save the dirstate file. (John Arbash Meinel, #765881)
936
* ``bzr tags`` will no longer choke on branches with ghost revisions in
937
their mainline and tags on revisions not in the branch ancestry.
938
(Jelmer Vernooij, #397556)
940
* ``bzr whoami`` will now display an error if both a new identity and
941
``--email`` were specified. (Jelmer Vernooij, #680449)
943
* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
944
(Vincent Ladeuil, #706835)
946
* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
948
(Martin Pool, #586341)
950
* Plugins incompatible with the current version of bzr no longer produce a
951
warning on every command invocation. Instead, a message is shown by
952
``bzr plugins`` and in crash reports.
953
(#704195, Martin Pool)
955
* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
956
preserves the identity of default parameter values.
957
(Andrew Bennetts, #718569)
959
* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
960
containing no rows. (Eric Siegerman, #715508)
962
* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
963
without an explicit public location. (Max Bowsher)
965
* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
966
number of available processors. (Jelmer Vernooij, #693140)
971
* Added ``Branch.heads_to_fetch`` method. Implementations of the Branch API
972
must now inherit or implement this method. (Andrew Bennetts, #721328)
974
* Added ``bzrlib.mergetools`` module with helper functions for working with
975
the list of external merge tools. (Gordon Tyler, #489915)
977
* All methods and arguments that were deprecated before 2.0
978
have been removed. (Jelmer Vernooij)
980
* Branch formats should now be registered on the format registry
981
(``bzrlib.branch.format_registry``) rather than using the class
982
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)
984
* ``Branch.set_revision_history`` is now deprecated.
987
* ``BranchFormat.supports_leaving_lock()`` and
988
``RepositoryFormat.supports_leaving_lock`` flags have been added.
991
* ``Branch.fetch`` implementations must now accept an optional
992
``fetch_tags`` keyword argument. (Andrew Bennetts)
994
* ``Branch.import_last_revision_info`` is deprecated. Use the
995
``import_last_revision_info_and_tags`` method instead.
998
* Because it was too specific to BzrDir implementations,
999
``ControlDir.sprout`` no longer has a default implementation; it now
1000
raises ``NotImplementedError``. (Jelmer Vernooij, #717937)
1002
* ``bzrlib.deprecated_graph`` has been removed. ``bzrlib.graph``
1003
scales better tree and should be used instead.
1004
(Jelmer Vernooij, #733612)
1006
* ``ControlDirFormat.register_format`` has been removed. Instead,
1007
``Prober`` implementations should now implement a ``known_formats``
1008
method. (Jelmer Vernooij)
1010
* ControlDirFormats can now provide a ``check_status`` method and
1011
raise a custom exception or warning when an unsupported or deprecated
1012
format is being opened. (Jelmer Vernooij, #731311)
1014
* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
1015
Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
1016
``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
1017
instead. (Jelmer Vernooij, #721971)
1019
* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
1020
indicates whether the components of the bzrdir can be upgraded
1021
independent of the ``BzrDir``. (Jelmer Vernooij)
1023
* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
1024
now deprecated in favour of the ``BzrProber.formats`` format registry.
1027
* ``ControlDir`` implementations no longer have to provide the
1028
``get_branch_transport``, ``get_workingtree_transport`` and
1029
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)
1031
* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
1032
``bzrlib.controldir``. (Jelmer Vernooij)
1034
* Repository formats can now provide
1035
``_get_extra_interrepo_test_combinations`` in the same module
1036
to provide extra test combinations for ``bzrlib.tests.per_repository``.
1039
* Repository formats should now be registered on the format registry
1040
(``bzrlib.repository.format_registry``) rather than using the class
1041
methods on ``RepositoryFormat``. (Jelmer Vernooij)
1043
* Repository formats can now indicate they do not support the full
1044
VersionedFiles API by setting the ``supports_full_versioned_files``
1045
attribute to False. A subset of the VersionedFiles API
1046
(signatures and text graphs) still needs to be supported.
1049
* Repository formats have a new method ``is_deprecated`` that
1050
implementations can override to return True to trigger a deprecation
1051
warning. (Jelmer Vernooij)
1053
* The ``revision_id`` parameter of
1054
``Repository.search_missing_revision_ids`` and
1055
``InterRepository.search_missing_revision_ids`` is deprecated. It is
1056
replaced by the ``revision_ids`` parameter. (Andrew Bennetts)
1058
* Working tree formats should now be registered on the format registry
1059
(``bzrlib.working_tree.format_registry``) rather than using the class
1060
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)
1062
* Exporting may now be done with a generator
1063
(``bzrlib.export.get_export_generator``) (Geoff/xaav, #791005)
1068
* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
1069
out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
1070
outside of tests. This class makes it easier to track exceptions in threads
1071
by catching them so they can be re-raised in the controlling thread. It's
1072
available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)
1074
* Correctly propogate malloc failures from diff-delta.c code as MemoryError
1075
so OOM conditions during groupcompress are clearly reported. This entailed a
1076
change to several function signatures. (Martin [gz], #633336)
1078
* ``HookPoint.lazy_hook`` and ``Hooks.install_named_lazy_hook`` can install
1079
hooks for which the callable is loaded lazily. (Jelmer Vernooij)
1084
* The Range parsing for HTTP requests will correctly parse incomplete ranges.
