*****************************
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 hook server_exception in bzrlib.smart.server to catch any
24
exception caused while running bzr serve. (Jonathan Riddell,
30
.. Improvements to existing commands, especially improved performance
31
or memory usage, or better results.
36
.. Fixes for situations where bzr would previously crash or give incorrect
37
or undesirable results.
39
* Fix a race condition for ``server_started`` hooks leading to a spurious
40
test failure. (Vincent Ladeuil, #789167)
42
* Handle files that get created but don't get used during TreeTransform.
43
``open()`` can create a file, and still raise an exception before it
44
returns. So anything we might have created, make sure we destroy during
45
``finalize()``. (Martin [gz], #597686)
47
* ``pack_repo`` now uses ``Transport.move`` instead of
48
``Transport.rename``, deleting any existing targets even on SFTP.
49
(Martin von Gagern, #421776)
51
* Pass the ``build_mo`` command to the rest of the setup() calls in
52
setup.py. The ``bdist_wininst`` and ``py2exe`` code paths were failing
53
because ``build_mo`` became a required step that they didn't know about.
54
(John Arbash Meinel, #787122)
56
* Reports the original error when an InvalidHttpResponse exception is
57
encountered to facilitate debug. (Vincent Ladeuil, #788530)
59
* Reports a non-existant file error when trying to merge in a file
60
that does not exist. (Jonathan Riddell, #330063)
62
* ``UIFactory.prompt``, ``UIFactory.get_username``,
63
``UIFactory.get_password`` and ``UIFactory.get_boolean`` now require a
64
unicode prompt to be passed in. (Jelmer Vernooij, #592083)
69
.. Improved or updated documentation.
71
* Improve documentation of ``bzr merge --force``.
72
(Neil Martinsen-Burrell, #767307)
77
.. Changes that may require updates in plugins or other code that uses
83
.. Major internal changes, unlikely to be visible to users or plugin
84
developers, but interesting for bzr developers.
86
* ``tools/check-newsbugs.py`` accepts a ``--browser`` option to open
87
corresponding launchpad pages in a browser. (Vincent Ladeuil)
92
.. Fixes and changes that are only relevant to bzr's test framework and
93
suite. This can include new facilities for writing tests, fixes to
94
spurious test failures and changes to the way things should be tested.
96
* Fix deadlock in `TestImportTariffs.test_simple_serve` when stderr gets
97
more output than fits in the default buffer. This was happening on the
98
Windows buildslave, and could easily happen in other circumstances where
99
the default OS buffer size for pipes is small or the ``python -v``
100
output is large. (Andrew Bennetts, #784802)
102
* Fix spurious test failure on OSX for WorkingTreeFormat2.
103
(Vincent Ladeuil, #787942)
105
* Show log file contents from subprocesses started by
106
`start_bzr_subprocess` in test failure details. This may help diagnose
107
strange hangs and failures involving subprocesses. (Andrew Bennetts)
109
* Skip ``utextwrap`` tests when ``sphinx`` breaks text_wrap by an hostile
110
monkeypatch to textwrap.TextWrapper.wordsep_re.
111
(Vincent Ladeuil, #785098)
113
* Multiple ``selftest --exclude`` options are now combined instead of
114
overriding each other. (Vincent Ladeuil, #746991)
116
* `TestImportTariffs` no longer uses the real ``$HOME``. This prevents it
117
from polluting ``$HOME/.bzr.log`` or being accidentally influenced by
118
user configuration such as aliases. It still runs with all the user's
119
plugins enabled, as intended.
120
(Vincent Ladeuil, Andrew Bennetts, #789505)
128
This is the third beta of the 2.4 series, leading to a 2.4.0 release in
129
August 2011. Beta releases are suitable for everyday use but may cause some
130
incompatibilities with plugins.
132
This release includes all bug fixed in previous series known at the time of

*****************************
139
.. These may require users to change the way they use Bazaar.
141
* ``bzr-2.4`` has officially dropped support for python2.4 and python2.5.
142
We will continue to maintain ``bzr-2.3`` for people who still need to
143
use those versions of python. (John Arbash Meinel)
148
.. New commands, options, etc that users may wish to try out.
150
* The text compressor used for 2a repositories now has a tweakable
151
parameter that can be set in bazaar.conf.
152
``bzr.groupcompress.max_entries_per_source`` default of 65536.
153
When doing compression, we build up an index of locations to match
154
against. Setting this higher will result in slightly better compression,
155
at a cost of more memory. Note that a value of 65k represents fully
156
sampling a 1MB file. So this only has an effect when compressing texts
157
larger than N*16 bytes. (John Arbash Meinel, #602614)
162
.. Improvements to existing commands, especially improved performance
163
or memory usage, or better results.
165
* ``bzr branch --stacked`` from a smart server uses the network a little
166
more efficiently. For a simple branch it reduces the number of
167
round-trips by about 20%. (Andrew Bennetts)
169
* ``bzr log --line`` scales the width of the author field with the size of
170
the line. This means that the full author name is shown when the
171
environment variable BZR_COLUMNS=0. (Neil Martinsen-Burrell)
173
* ``bzr pull`` now properly triggers the fast
174
``CHKInventory.iter_changes`` rather than the slow generic
175
inter-Inventory changes. It used to use a ``DirStateRevisionTree`` as
176
one of the source trees, which is faster when we have to read the whole
177
inventory anyway, but much slower when we can get just the delta out of
178
the repository. On a 70k record tree, this changes ``bzr pull`` from 28s
179
down to 17s. (John Arbash Meinel, #780677)
181
* Slightly reduced memory consumption when fetching into a 2a repository
182
by reusing existing caching a little better. (Andrew Bennetts)
184
* Speed up ``bzr status`` by a little bit when there are a couple of
185
modified files. We now track how many files we have seen that need
186
updating, and only rewrite the dirstate file if enough of them have
187
changed. The default is 10, and can be overridden by setting the branch
188
option "``bzr.workingtree.worth_saving_limit``".
189
(Ian Clatworthy, John Arbash Meinel, #380202)
191
* Speed up ``bzr uncommit``. Instead of resetting the dirstate from
192
scratch, use ``update_basis_by_delta``, computing the delta from the
193
repository. (John Arbash Meinel, #780544)
198
.. Fixes for situations where bzr would previously crash or give incorrect
199
or undesirable results.
201
* All Tree types can now be exported as tar.*, zip or directories.
204
* ``bzr merge --no-remember location`` never sets ``submit_branch``.
205
(Vincent Ladeuil, #782169)
207
* ``bzr pull --no-remember location`` never sets
208
``parent_location``. ``bzr push --no-remember location`` never
209
sets ``push_location``. ``bzr send --no-remember
210
submit_location public_location`` never sets ``submit_branch``
211
nor ``public_branch``. (Vincent Ladeuil)
213
* Conflicts involving non-ascii filenames are now properly reported rather
214
than failing with a UnicodeEncodeError. (Martin [GZ], #686161)
216
* Correct parent is now set when using 'switch -b' with bound branches.
217
(A. S. Budden, #513709)
219
* Fix `bzr plugins` regression in bzr 2.4 which resulted in a traceback
220
from writelines on ckj terminals. (Martin [GZ], #754082)
222
* ``WT.inventory`` and ``WT.iter_entries_by_dir()`` was not correctly
223
reporting subdirectories that were tree references (in formats that
224
supported them). (John Arbash Meinel, #764677)
226
* Merging into empty branches now gives an error as this is currently
227
not supported. (Jonathan Riddell, #242175)
229
* Do not show exception to user on pointless commit error (Jonathan
232
* ``WT.update_basis_by_delta`` no longer requires that the deltas match
233
the current WT state. This allows ``update_basis_by_delta`` to be used
234
by more commands than just commit. Updating with a delta allows us to
235
not load the whole inventory, which can take 10+s with large trees.
236
(Jonathan Riddell, John Arbash Meinel, #781168)
242
.. Improved or updated documentation.
244
* Restore the workaround for option names including dots (--1.14) which was
245
disabled when we stopped listing --1.9 as a format.
246
(Vincent Ladeuil, #782289)
251
.. Changes that may require updates in plugins or other code that uses
254
* ``annotate_file`` has been deprecated in favor of
255
``annotate_file_revision_tree``. (Jelmer Vernooij, #775598)
257
* ``Branch.fetch`` now takes an optional ``limit`` argument.
258
(Andrew Bennetts, Jelmer Vernooij, #750175)
260
* ``Inter.get`` now raises ``NoCompatibleInter`` if there are no
261
compatible optimisers rather than an instance of the class it is called
262
on. (Jelmer Vernooij)
264
* ``Branch.push`` now takes a ``lossy`` argument.
265
``Branch.lossy_push`` has been removed.
268
* New method ``Repository.get_file_graph`` which can return the
269
per-file revision graph. (Jelmer Vernooij, #775578)
271
* The default implementation of ``Branch`` is now oriented to
272
storing the branch tip. Branch implementations which store the full
273
history should now subclass ``FullHistoryBzrBranch``.
274
``Branch._last_revision_info`` has been renamed to
275
``Branch._read_last_revision_info`` (Jelmer Vernooij)
277
* ``Tree.__iter__`` has been deprecated; use ``Tree.all_file_ids``
278
instead. (Jelmer Vernooij)
280
* ``Tree.get_symlink_target`` now takes an optional ``path``
281
argument. (Jelmer Vernooij)
286
.. Major internal changes, unlikely to be visible to users or plugin
287
developers, but interesting for bzr developers.
289
* ``MutableTree.smart_add`` now uses inventory deltas.
290
(Jelmer Vernooij, #146165)
292
* Removed ``bzrlib.branch._run_with_write_locked_target`` as
293
``bzrlib.cleanup`` provides the same functionality in a more general
294
way. (Andrew Bennetts)
299
.. Fixes and changes that are only relevant to bzr's test framework and
300
suite. This can include new facilities for writing tests, fixes to
301
spurious test failures and changes to the way things should be tested.
303
* A test that was expected to fail but passes instead now counts as a failure
304
catching up with new testtools and subunit handling. (Martin [GZ], #654474)
306
* Make it easier for plugins to reuse the per_workingtree scenarios by
307
restoring the wt_scenarios helper that was accidentally deleted.
308
(Vincent Ladeuil, #783472)
310
* Removed ``test_breakin`` tests that were excessively prone to hanging,
311
did not work on Wine, and partly already disabled.
312
(Martin Pool, #408814, #746985)
314
* Windows locations are different and should be tested accordingly.
315
(Vincent Ladeuil, #788131)

This is the second beta of the 2.4 series, leading to a 2.4.0 release in
323
August 2011. Beta releases are suitable for everyday use but may cause some
324
incompatibilities with plugins.
326
This release includes all bug fixed in previous series known at the time of

External Compatibility Breaks
331
*****************************
333
.. These may require users to change the way they use Bazaar.
335
* Two command synonyms for ``bzr branch`` have been deprecated, to avoid
336
confusion and to allow the names to later be reused. The removed names
337
are: ``get`` and ``clone``. (Martin Pool, #506265)
342
.. New commands, options, etc that users may wish to try out.
344
* ``bzr commit`` now supports a ``--lossy`` argument that can be used
345
to discard any data that can not be natively represented when committing
346
to a foreign VCS. (Jelmer Vernooij, #587721)
351
.. Improvements to existing commands, especially improved performance
352
or memory usage, or better results.
354
* ``bzr merge`` in large trees is now significantly faster. On a 70k entry
355
tree, the time went from ~3min down to 30s. This also effects ``bzr pull``
356
and ``bzr update`` since they use the same merge logic to update the
357
WorkingTree. (John Arbash Meinel, #759091)
359
* ``bzr revert`` now properly uses ``bzr status``'s optimized
360
``iter_changes``. This can be a significant performance difference (33s
361
to 5s on large trees). (John Arbash Meinel, #759096)
363
* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
364
the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
365
being handed off to the remote server anyway (xmlrpc has been mapping
366
``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
367
than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
368
months now.) By doing it ourselves, we can cut out substantial startup
369
time. From Netherlands to London it was taking 368ms to do the XMLRPC
370
call as much as 2s from Sydney. You can test the local logic by using
371
``-Dlaunchpad``. (John Arbash Meinel, #397739)
373
* When building a new WorkingTree (such as during ``bzr co`` or
374
``bzr branch``) we now properly store the stat and hash of files that
375
are old enough. This saves a fair amount of time on the first
376
``bzr status`` (on a 500MB tree, it saves about 30+s).
377
(John Arbash Meinel, #740932)
383
.. Fixes for situations where bzr would previously crash or give incorrect
384
or undesirable results.
386
* Arguments that can't be decoded to unicode in the current posix locale give
387
a clearer error message without a traceback. (Martin [gz], #745712)
389
* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
390
mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
391
these default values aren't relied on very often so this probably
392
wasn't causing any trouble. (Andrew Bennetts)
394
* ``bzr log`` now works on revisions which are not in the current branch.
395
(Matt Giuca, #241998)
397
* Don't rewrite the dirstate file when non-interesting changes have
398
occurred. This can significantly improve 'bzr status' times when there
399
are only small changes to a large tree.
400
(Ian Clatworthy, John Arbash Meinel, #380202)
402
* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
404
* ``bzrlib.merge.Merge`` now calls ``iter_changes`` without
405
``include_unversioned=True``. This makes it significantly faster in many
406
cases, because it only looks at modified files, rather than building
407
information about all files. This can cause failures in other
408
TreeTransform code, because it had been expecting to know the names of
409
things which had not changed (such as parent directories). All cases we
410
know about so far have been fixed, but there may be fallout for edge
411
cases that we are missing. (John Arbash Meinel, #759091)
413
* ``SFTPTransport`` is more pro-active about closing file-handles. This
414
reduces the chance of having threads fail from async requests while
415
running the test suite. (John Arbash Meinel, #656170)
417
* Standalone bzr.exe installation on Windows: user can put additional python
418
libraries into ``site-packages`` subdirectory of the installation directory,
419
this might be required for "installing" extra dependencies for some plugins.
420
(Alexander Belchenko, #743256)
422
* ``transform.revert()`` has been updated to use
423
``wt.iter_changes(basis_tree)`` rather than
424
``basis_tree.iter_changes(wt)``. This allows the optimized code path to
425
kick in, improving ``bzr revert`` times significantly (33s to 4s on
426
large trees, 0.7s to 0.3s on small trees.) (John Arbash Meinel, #759096)
428
* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
429
parameter. If supplied, when the transform is applied, it will then call
430
``self._tree._observed_sha1`` for those files. This lets us update the
431
hash-cache for content that we create, preventing us from re-reading the
432
content in the next ``bzr status``. (John Arbash Meinel, #740932)
437
* Added a section about using a shared SSH account on a server for bzr+ssh
438
access. (Russell Smith)
440
* The documentation now recommends using SSH rather than SFTP in the
441
tutorials and the examples, because that will generally be much faster
442
and better in cases where it can be used. SFTP is still available and
443
mentioned as an alternative. (Martin Pool, #636712)
448
.. Changes that may require updates in plugins or other code that uses
451
* ``Branch.update_revisions`` has been made private and should no
452
longer be used by external users. Use ``Branch.pull`` or ``Branch.push``
453
instead. (Jelmer Vernooij, #771765)
455
* Commands now have an `invoked_as` attribute, showing the name under
456
which they were called before alias expansion.
459
* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
462
* If you call `bzrlib.initialize` but forget to enter the resulting object
463
as a context manager, bzrlib will now be initialized anyhow.
464
(Previously simple programs calling bzrlib might find the library was
465
mysteriously silent.)
468
* Inventory-specific functionality has been split out of ``Tree`` into
469
a new ``InventoryTree`` class. Tree instances no longer
470
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
472
* Inventory-specific functionality has been split out of ``RevisionTree``
473
into a new ``InventoryRevisionTree`` class. RevisionTree instances no
474
longer necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
476
* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)
478
* ``revision_graph_can_have_wrong_parents`` is now an attribute
479
on ``RepositoryFormat`` rather than a method on ``Repository``.
482
* ``Testament`` now takes a ``tree`` rather than an
483
``inventory``. (Jelmer Vernooij, #762608)
485
* ``TestCase.failUnlessExists`` and ``failIfExists`` are deprecated in
486
favour of ``assertPathExists`` and ``assertPathDoesNotExist``
490
* The ``revno`` parameter of ``log.LogRevision`` may now be None,
491
representing a revision which is not in the current branch.
492
(Matt Giuca, #241998)
494
* The various knit pack repository format classes have been moved
495
from ``bzrlib.repofmt.pack_repo`` to
496
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)
498
* ``RevisionTree`` now has a new method ``get_file_revision``.
501
* ``WorkingTree`` no longer provides an ``inventory``. Instead,
502
all inventory-related functionality is now on the subclass
503
``InventoryWorkingTree`` that all native Bazaar working tree
504
implementations derive from. (Jelmer Vernooij)
509
.. Major internal changes, unlikely to be visible to users or plugin
510
developers, but interesting for bzr developers.
512
* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
513
functions on Linux, but they are wrapped on Windows so that fstat
514
matches lstat results across all python versions.
517
* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
518
happened to be updated as a side-effect of commit, but if we start using
519
the function elsewhere we might as well do it directly.
525
.. Fixes and changes that are only relevant to bzr's test framework and
526
suite. This can include new facilities for writing tests, fixes to
527
spurious test failures and changes to the way things should be tested.
529
* Stop using `failIf`, `failUnless`, `failIfEqual`, etc, that give
530
`PendingDeprecationWarnings` on Python2.7.
531
(Martin Pool, #760435)
539
This is the first beta of the 2.4 series, leading up to a 2.4.0
540
release in August 2011. Beta releases are suitable for everyday use
541
but may cause some incompatibilities with plugins. Some plugins may need
542
small updates to work with 2.4b1.
544
External Compatibility Breaks
545
*****************************
552
* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
553
in GNU format. See ``bzr help changelog_merge`` for details.
556
* Configuration options can now use references to other options in the same
557
file by enclosing them with curly brackets (``{other_opt}``). This makes it
558
possible to use, for example,
559
``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
560
using a loom. During the beta period, the default behaviour is to disable
561
this feature. It can be activated by declaring ``bzr.config.expand = True``
562
in ``bazaar.conf``. (Vincent Ladeuil)
564
* External merge tools can now be configured in bazaar.conf. See
565
``bzr help configuration`` for more information. (Gordon Tyler, #489915)
567
* The ``lp:`` directory service now supports Launchpad's QA staging.
568
(Jelmer Vernooij, #667483)
573
* A new hidden command ``bzr repair-workingtree``. This is a way to force
574
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
575
workaround. (John Arbash Meinel)
577
* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
578
This allows formats from plugins (such as looms) to efficiently tell the
579
client which revisions need to be fetched. (Andrew Bennetts)
581
* Branching, merging and pulling a branch now copies revisions named in
582
tags, not just the tag metadata. (Andrew Bennetts, #309682)
584
* ``bzr cat-revision`` no longer requires a working tree.
585
(Jelmer Vernooij, #704405)
587
* ``bzr export --per-file-timestamps`` for .tar.gz files will now
588
override the mtime for trees exported on Python 2.7 and later, which
589
expose the 'mtime' field in gzip files. This makes the output of
590
``bzr export --per-file-timestamps`` for a particular tree
591
deterministic. (Jelmer Vernooij, #711226)
593
* ``bzr export --format=zip`` can now export to standard output,
594
like the other exporters can. (Jelmer Vernooij, #513752)
596
* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
597
(Jelmer Vernooij, #551714)
599
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
600
sped up dramatically for large trees. Iterating by dir is not the best
601
way to load data from a CHK inventory, so it preloads all the items in
602
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
603
of CHK data, down to just 150MB.) This has noticeable affects for things
604
like building checkouts, etc. (John Arbash Meinel, #737234)
609
* A MemoryError thrown on the server during a remote operation will now be
610
usefully reported, and other unexpected errors will include the class name.
611
(Martin [gz], #722416)
613
* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
614
(Andrew King, #537442)
616
* ``bzr export`` to zip files will now set a mode on directories.
617
(Jelmer Vernooij, #207253)
619
* ``bzr export`` to tgz files will only write out the basename of the
620
tarfile to the gzip file. (Jelmer Vernooij, #102234)
622
* ``bzr push --overwrite`` with an older revision specified will now correctly
623
roll back the target branch. (Jelmer Vernooij, #386576)
625
* ``bzr lp-propose`` can now propose merges against packaging branches on
626
Launchpad without requiring the target branch to be specified.
627
(Jelmer Vernooij, #704647)
629
* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
630
instead leave setting the reviewer up to Launchpad if it was not specified.
631
(Jelmer Vernooij, #583772)
633
* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
634
(Jelmer Vernooij, #213185)
636
* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
637
paths, however they may still print junk if not on a UTF-8 terminal.
638
(Martin [gz], #707954)
640
* ``bzr reconfigure --unstacked`` now copies revisions (and their
641
ancestors) named in tags into the unstacked repository, not just the
642
ancestry of the branch's tip. (Andrew Bennetts, #401646)
644
* ``bzr serve`` no longer crashes when a server_started hook is installed and
645
IPv6 support is available on the system. (Jelmer Vernooij, #293697)
647
* ``bzr status`` will not rewrite the dirstate file if it only has
648
'trivial' changes. (Currently limited to dir updates and newly-added
649
files changing state.) This saves a bit of time for regular operations.
650
eg. ``bzr status`` in a 100k tree takes 1.4s to compute the status, but 1s
651
to re-save the dirstate file. (John Arbash Meinel, #765881)
653
* ``bzr tags`` will no longer choke on branches with ghost revisions in
654
their mainline and tags on revisions not in the branch ancestry.
655
(Jelmer Vernooij, #397556)
657
* ``bzr whoami`` will now display an error if both a new identity and
658
``--email`` were specified. (Jelmer Vernooij, #680449)
660
* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
661
(Vincent Ladeuil, #706835)
663
* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
665
(Martin Pool, #586341)
667
* Plugins incompatible with the current version of bzr no longer produce a
668
warning on every command invocation. Instead, a message is shown by
669
``bzr plugins`` and in crash reports.
670
(#704195, Martin Pool)
672
* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
673
preserves the identity of default parameter values.
674
(Andrew Bennetts, #718569)
676
* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
677
containing no rows. (Eric Siegerman, #715508)
679
* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
680
without an explicit public location. (Max Bowsher)
682
* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
683
number of available processors. (Jelmer Vernooij, #693140)
688
* Added ``Branch.heads_to_fetch`` method. Implementations of the Branch API
689
must now inherit or implement this method. (Andrew Bennetts, #721328)
691
* Added ``bzrlib.mergetools`` module with helper functions for working with
692
the list of external merge tools. (Gordon Tyler, #489915)
694
* All methods and arguments that were deprecated before 2.0
695
have been removed. (Jelmer Vernooij)
697
* Branch formats should now be registered on the format registry
698
(``bzrlib.branch.format_registry``) rather than using the class
699
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)
701
* ``Branch.set_revision_history`` is now deprecated.
704
* ``BranchFormat.supports_leaving_lock()`` and
705
``RepositoryFormat.supports_leaving_lock`` flags have been added.
708
* ``Branch.fetch`` implementations must now accept an optional
709
``fetch_tags`` keyword argument. (Andrew Bennetts)
711
* ``Branch.import_last_revision_info`` is deprecated. Use the
712
``import_last_revision_info_and_tags`` method instead.
715
* Because it was too specific to BzrDir implementations,
716
``ControlDir.sprout`` no longer has a default implementation; it now
717
raises ``NotImplementedError``. (Jelmer Vernooij, #717937)
719
* ``bzrlib.deprecated_graph`` has been removed. ``bzrlib.graph``
720
scales better tree and should be used instead.
721
(Jelmer Vernooij, #733612)
723
* ``ControlDirFormat.register_format`` has been removed. Instead,
724
``Prober`` implementations should now implement a ``known_formats``
725
method. (Jelmer Vernooij)
727
* ControlDirFormats can now provide a ``check_status`` method and
728
raise a custom exception or warning when an unsupported or deprecated
729
format is being opened. (Jelmer Vernooij, #731311)
731
* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
732
Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
733
``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
734
instead. (Jelmer Vernooij, #721971)
736
* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
737
indicates whether the components of the bzrdir can be upgraded
738
independent of the ``BzrDir``. (Jelmer Vernooij)
740
* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
741
now deprecated in favour of the ``BzrProber.formats`` format registry.
744
* ``ControlDir`` implementations no longer have to provide the
745
``get_branch_transport``, ``get_workingtree_transport`` and
746
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)
748
* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
749
``bzrlib.controldir``. (Jelmer Vernooij)
751
* Repository formats can now provide
752
``_get_extra_interrepo_test_combinations`` in the same module
753
to provide extra test combinations for ``bzrlib.tests.per_repository``.
756
* Repository formats should now be registered on the format registry
757
(``bzrlib.repository.format_registry``) rather than using the class
758
methods on ``RepositoryFormat``. (Jelmer Vernooij)
760
* Repository formats can now indicate they do not support the full
761
VersionedFiles API by setting the ``supports_full_versioned_files``
762
attribute to False. A subset of the VersionedFiles API
763
(signatures and text graphs) still needs to be supported.
766
* Repository formats have a new method ``is_deprecated`` that
767
implementations can override to return True to trigger a deprecation
768
warning. (Jelmer Vernooij)
770
* The ``revision_id`` parameter of
771
``Repository.search_missing_revision_ids`` and
772
``InterRepository.search_missing_revision_ids`` is deprecated. It is
773
replaced by the ``revision_ids`` parameter. (Andrew Bennetts)
775
* Working tree formats should now be registered on the format registry
776
(``bzrlib.working_tree.format_registry``) rather than using the class
777
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)
782
* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
783
out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
784
outside of tests. This class makes it easier to track exceptions in threads
785
by catching them so they can be re-raised in the controlling thread. It's
786
available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)
788
* Correctly propogate malloc failures from diff-delta.c code as MemoryError
789
so OOM conditions during groupcompress are clearly reported. This entailed a
790
change to several function signatures. (Martin [gz], #633336)
792
* ``HookPoint.lazy_hook`` and ``Hooks.install_named_lazy_hook`` can install
793
hooks for which the callable is loaded lazily. (Jelmer Vernooij)
798
* The Range parsing for HTTP requests will correctly parse incomplete ranges.
