:2.2.2: NOT RELEASED YET
22
* Using bzr with `lp:` urls behind an http proxy should work.
23
(Robert Collins, #558343)
40
* Add ``tests/ssl_certs/ca.crt`` to the required test files list. Test
41
involving the pycurl https test server fail otherwise when running
42
selftest from an installed version. (Vincent Ladeuil, #651706)
44
* Fix tests that failed when run under ``LANG=C``.
45
(Andrew Bennetts, #632387)
47
* Skip tests that needs a bzr source tree when there isn't one. This is
48
needed to succesfully run the test suite for installed versions.
49
(Vincent Ladeuil, #644855).
51
* Skip the tests that requires respecting the chmod bits when running as
52
root. Including the one that wasn't present in 2.1.
53
(Vincent Ladeuil, #646133)
61
This is a bugfix release which also includes bugfixes from 2.0.6 and
62
2.1.3. None are critical, but upgrading is recommended for all users on
68
* Additional merges after an unrelated branch has been merged with its
69
history no longer crash when deleted files are involved.
70
(Vincent Ladeuil, John Arbash Meinel, #375898)
72
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
73
previously-unversioned directory within the tree: the directory is
75
(Martin Pool, #192859)
77
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
78
target of the symlink.
79
(Martin Pool, John Arbash Meinel, #128562)
81
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
82
permissions as ``.bzr`` directory on a POSIX OS.
83
(Parth Malwankar, #262450)
85
* CommitBuilder now uses the committer instead of _config.username to generate
86
the revision-id. (Aaron Bentley, #614404)
88
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
89
way which should help avoid problems with concurrent writers.
90
(Vincent Ladeuil, #525571)
92
* Cope with Microsoft FTP server that returns reply '250 Directory
93
created' when mkdir succeeds. (Martin Pool, #224373)
95
* Don't traceback trying to unversion children files of an already
96
unversioned directory. (Vincent Ladeuil, #494221)
98
* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
99
contains only NUL bytes). Instead warn the user, and allow ``bzr
100
break-lock`` to remove it. (Andrew Bennetts, #619872)
102
* Fix ``AttributeError on parent.children`` when adding a file under a
103
directory that was a symlink in the previous commit.
104
(Martin Pool, #192859)
106
* Fix ``AttributeError: 'NoneType' object has no attribute 'close'`` in
107
``_close_ssh_proc`` when using ``bzr+ssh://``. This was causing
108
connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on
109
stderr in some other circumstances. (Andrew Bennetts, #633745)
111
* Only call ``setlocale`` in the bzr startup script on posix systems. This
112
avoids an issue with the newer windows C runtimes used by Python 2.6 and
113
later which can mangle bytestrings printed to the console.
114
(Martin [gz], #631350)
116
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
117
which can result in "missing referenced chk root keys" errors when
118
fetching from repositories with affected revisions.
119
(Andrew Bennetts, #522637)
121
* Raise ValueError instead of a string exception.
122
(John Arbash Meinel, #586926)
124
* Reduce peak memory by one copy of compressed text.
125
(John Arbash Meinel, #566940)
127
* Repositories accessed via a smart server now reject being stacked on a
128
repository in an incompatible format, as is the case when accessing them
129
via other methods. This was causing fetches from those repositories via
130
a smart server (e.g. using ``bzr branch``) to receive invalid data.
131
(Andrew Bennetts, #562380)
133
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
134
error. This error was caused by 2.0 not being updated when upstream
135
python merged the end of run patch, which chose ``stopTestRun`` rather than
136
``done``. (Robert Collins, #571437)
138
* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``
139
being thrown from ``xml_serializer`` on certain cElementTree setups.
140
(Martin [gz], #254278)
142
* Upgrading or fetching from a non-rich-root repository to a rich-root
143
repository (e.g. from pack-0.92 to 2a) no longer fails with
144
``'Inter1and2Helper' object has no attribute 'source_repo'``. This was
145
a regression from Bazaar 2.1. (Andrew Bennetts, #636930)
147
* When passing a file to ``UTF8DirReader`` make sure to close the current
148
directory file handle after the chdir fails. Otherwise when passing many
149
filenames into a command line ``bzr status`` we would leak descriptors.
150
(John Arbash Meinel, #583486)
155
* Fix a lot of references in the docs to the old http://bazaar-vcs.org to
156
the new http://bazaar.canonical.com or http://wiki.bazaar.canonical.com
157
(John Arbash Meinel, #617503)
162
* Remove used and broken code path in ``BranchInitHookParams.__repr__``.
168
* ``build_tree_contents`` can create symlinks.
169
(Martin Pool, John Arbash Meinel)
171
* Tracebacks from a parameterized test are no longer reported against every
172
parameterization of that test. This was done by adding a hack to
173
``bzrlib.tests.clone_test`` so that it no longer causes
174
testtools.TestCase instances to share a details dict.
175
(Andrew Bennetts, #625574)
183
This release marks the start of another long-term-stable series. From
184
here, we will only make bugfix releases on the 2.2 series (2.2.1, etc),
185
while 2.3 will become our new development series. The 2.0 and 2.1 series
186
will also continue to get bugfixes. (Currently 2.0 is planned to be
187
supported for another 6 months.)
189
This is primarily a bugfix and polish release over the 2.1 series, with
190
a large number of bugs fixed (>120), and some performance improvements.
192
There are some compatibility changes in this release. For users of bzrlib
193
as a library, we now request that they call ``bzrlib.initialize`` and use
194
the returned context manager appropriately. For commandline users we no
195
longer guess user identity for ``bzr commit``, users must specify their
196
identity using ``bzr whoami`` (you don't need to specify your identity for
197
readonly operations).
199
Users are encouraged to upgrade from the other stable series.
204
* BzrError subclasses no longer support the name "message" to be used
205
as an argument for __init__ or in _fmt format specification as this
206
breaks in some Python versions. errors.LockError.__init__ argument
207
is now named "msg" instead of earlier "message".
208
(Parth Malwankar, #603461)
210
* The old ``bzr selftest --benchmark`` option has been removed.
211
<https://launchpad.net/bzr-usertest> is an actively-maintained
212
macrobenchmark suite.
218
* ``bzr ignore PATTERNS`` exits with error if a bad pattern is supplied.
219
``InvalidPattern`` exception error message now shows faulting
221
(Parth Malwankar #300062)
223
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
224
way which should help avoid problems with concurrent writers.
225
(Vincent Ladeuil, #525571)
227
* Don't traceback trying to unversion children files of an already
228
unversioned directory. (Vincent Ladeuil, #494221)
230
* ``HTTP/1.1`` test servers now set a ``Content-Length`` header to comply
231
with pedantic ``HTTP/1.1`` clients. (Vincent Ladeuil, #568421)
233
* Progress bars prefer to truncate the text message rather than the
234
counters. The spinner is shown between the network transfer indicator
235
and the progress message. Progress bars are correctly cleared off when
236
they finish. (Martin Pool, #611127)
238
* Recursive binding for checkouts is now detected by bzr. A clear error
239
message is shown to the user. (Parth Malwankar, #405192)
244
* Add ``bzrlib.merge.MergeIntoMerger``, which can merge part or all of a
245
tree, and works with unrelated branches. (Andrew Bennetts)
247
* Add py2exe windows target ``bzrw.exe``. This allow for starting a Bazaar
248
GUI with out have a console open in the background.
249
(Gary van der Merwe, #433781)
254
* ``bzr help patterns`` now explains case insensitive patterns and
255
points to Python regular expression documentation.
256
(Parth Malwankar, #594386)
261
* Delete ``ProgressTask.note``, which was deprecated in 2.1.
266
* Unit test added to ensure that "message" is not uses as a format variable
267
name in BzrError subclasses as this conflicts with some Python versions.
268
(Parth Malwankar, #603461)
273
:Codename: Monkey Magic
277
This fourth and final beta in the 2.2 series now stabilizes the internal
278
APIs. Plugin authors are recommended to ensure their releases are
279
compatible, so that 2.2rc1 can be a true release candidate, containing
280
stable and compatible plugin versions.
282
For users of bzrlib as a library, one of the primary changes is to request
283
that they call ``bzrlib.initialize`` and use the returned context manager
286
Better interaction with ``bzr-loom`` to make sure branching from a loom
287
even over a smart server still yields a local loom. Not to mention lots of
293
* bzrlib library users now need to call ``__enter__`` and ``__exit__`` on
294
the result of ``bzrlib.initialize``. This change was made when fixing
295
the bad habit recent bzr versions have had of leaving progress bars
296
behind on the screen. That required calling another function before
297
exiting the program, and it made sense to provide a full context
298
manager at the same time. (Robert Collins)
300
* The ``bzr`` front end now requires a ``bzrlib.ui.ui_factory`` which is a
301
context manager in the Python 2.5 and above sense. The bzrlib base class
302
is such a manager, but third party UI factories which do not derive from
303
``bzrlib.ui.UIFactory`` will be incompatible with the command line front
306
* URLs like ``foo:bar/baz`` are now always parsed as a URL with scheme "foo"
307
and path "bar/baz", even if bzr does not recognize "foo" as a known URL
308
scheme. Previously these URLs would be treated as local paths.
315
* Support ``--directory`` option for a number of additional commands:
316
conflicts, merge-directive, missing, resolve, shelve, switch,
317
unshelve, whoami. (Martin von Gagern, #527878)
322
* ``bzr branch`` to a new repository with a default stacking policy no
323
longer transfers the full history unnecessarily.
324
(Andrew Bennetts, #597942)
326
* ``bzr init`` does not recursively scan directory contents anymore
327
leading to faster init for directories with existing content.
328
(Martin [gz], Parth Malwankar, #501307)
330
* ``bzr log --exclude-common-ancestry`` is now taken into account for
331
linear ancetries. (Vincent Ladeuil, #575631)
333
* ``bzr log -r branch:REMOTE`` can now properly log the remote branch,
334
rather than trying to fetch the data locally and failing because of a
335
readonly error. (Martin von Gagern, #149270)
337
* ``bzr pull`` now works when a lp: URL is explicitly defined as the parent
338
or pull location in locations.conf or branch.conf.
339
(Gordon Tyler, #534787)
341
* ``bzr reconfigure --unstacked`` now works with branches accessed via a
342
smart server. (Andrew Bennetts, #551525)
344
* ``BzrDir.find_branches`` should ignore branches with missing repositories.
345
(Marius Kruger, Robert Collins)
347
* ``BzrDir.find_bzrdirs`` should ignore dirs that raises PermissionDenied.
348
(Marius Kruger, Robert Collins)
350
* Ensure that wrong path specifications in ``BZR_PLUGINS_AT`` display
351
proper error messages. (Vincent Ladeuil, #591215)
353
* Explicitly removing ``--profile-imports`` option from parsed command-line
354
arguments on Windows, because bzr script does the same.
355
(Alexander Belchenko, #588277)
357
* Fetching was slightly confused about the best code to use and was
358
using a new code path for all branches, resulting in more lookups than
359
necessary on old branches. (Robert Collins, #593515)
361
* Final fix for 'no help for command' issue. We now show a clean message
362
when a command has no help, document how to set help more clearly, and
363
test that all commands available to the test suite have help.
364
(Robert Collins, #177500)
366
* Invalid patterns supplied to ``Globster`` or ``lazy_regex`` now raise
367
``InvalidPattern`` exception showing clear error message to the user.
368
(Parth Malwankar #300062)
370
* Progress output is cleaned up when exiting. (Aaron Bentley)
372
* Raise ValueError instead of a string exception.
373
(John Arbash Meinel, #586926)
375
* Relative imports in plugins are now handled correctly when using
376
BZR_PLUGINS_AT. (Vincent Ladeuil, #588959)
378
* ``ScriptRunner`` now strips off leading indentation from test scripts,
379
which previously caused "SyntaxError: No command for line".
382
* Show unicode filenames in diff headers using terminal encoding.
383
(Alexander Belchenko, Bug #382699)
384
NOTE for Windows users: If user need to save diff to file then user need to
385
change encoding of the terminal to ANSI encoding with command ``chcp XXX``
386
(e.g. ``chcp 1251`` for Russian Windows).
388
* URL displayed for use with ``break-lock`` when smart server sees lock
389
contention are now valid. Default timeout for lock contention retry is
390
now 30 seconds instead of 300 seconds.
391
(Parth Malwankar, #250451)
393
* ``walkdirs`` now raises a useful message when the filenames are not using
394
the filesystem encoding. (Eric Moritz, #488519)
396
* Enable debugging of bzr on windows with pdb and other tools. This was
397
broken because we call GetCommandLineW on windows. The fix adjusts the
398
command line we get to be the same length as sys.argv.
399
(Jason Spashett, Alexander Belchenko, #587868)
404
* Bazaar now reads data from SSH connections more efficiently on platforms
405
that provide the ``socketpair`` function, and when using paramiko.
406
(Andrew Bennetts, #590637)
408
* ``Branch.copy_content_into`` is now a convenience method dispatching to
409
a ``InterBranch`` multi-method. This permits ``bzr-loom`` and other
410
plugins to intercept this even when a ``RemoteBranch`` proxy is in use.
411
(Robert Collins, #201613)
413
* ``Branch`` formats can now be loaded lazily by registering a
414
``MetaDirBranchFormatFactory`` rather than an actual format. This will
415
cause the named format class to be loaded only when an enumeration of
416
formats is needed or when the format string for the object is
417
encountered. (Robert Collins, Jelmer Vernooij)
419
* The encoding that bzr uses to output things other than file content can
420
now be overridden via the output_encoding configuration option.
421
(Martin Pool, #340394)
423
* Use lazy imports in ``bzrlib/merge.py`` so that plugins like ``news_merge``
424
do not cause modules to be loaded unnecessarily just because the plugin
425
registers a merge hook. This improves ``bzr rocks`` time by about 25%
426
in a default installation (with just the core plugins).
432
* Added ``regression`` tag to our tags list. (Robert Collins)
434
* Improved our release checklist to have a bit less churn and leave things
435
ready-to-go for the next action (including other people doing
436
development). (Robert Collins)
438
* Remove obsolete discussion of PQM in documentation about how to
439
contribute to Bazaar. (Martin Pool, #588444)
444
* ``bzrlib.branch.InterBranch._get_branch_formats_to_test`` now returns
445
an iterable of format pairs, rather than just a single pair, permitting
446
InterBranch objects that work with multiple permutations to be
447
comprehensively tested. (Robert Collins)
449
* ``bzrlib.lsprof.profile`` will no longer silently generate bad threaded
450
profiles when concurrent profile requests are made. Instead the profile
451
requests will be serialised. Reentrant requests will now deadlock.
454
* ``bzrlib.knit.KnitSequenceMatcher``, which has been deprecated since
455
2007, has been deleted. Use ``PatienceSequenceMatcher`` from
456
``bzrlib.patiencediff`` instead. (Andrew Bennetts)
458
* ``bzrlib.re_compile_checked`` is now deprecated. Caller should handle
459
``bzrlib.errors.InvalidPattern`` exception thrown by ``re.match`` in
460
case the default error message not suitable for the use case.
463
* ``bzrlib.tests.blackbox.ExternalBase`` is deprecated. It provided only
464
one method ``check_output``, and we now recommend checking command
465
output using ``run_script``. (Martin Pool)
467
* ``bzrlib.transport.ssh.SSHVendor.connect_ssh`` now returns an object
468
that implements the interface of ``bzrlib.transport.ssh.SSHConnection``.
469
Third-party implementations of ``SSHVendor`` may need to be updated
470
accordingly. Similarly, any code using ``SSHConnection`` directly will
471
need to be updated. (Andrew Bennetts)
473
* The constructor of ``bzrilb.smart.medium.SmartSSHClientMedium`` has
474
changed to take an ``SSHParams`` instance (replacing many individual
475
values). (Andrew Bennetts)
480
* ``bzrlib.osutils.get_terminal_encoding`` will now only mutter its
481
selection when explicitly requested; this avoids many duplicate calls
482
being logged when helpers, wrappers and older code that manually calls
483
it are executed it is now logged deliberately by the ui setup code.
486
* Improved ``bzrlib.urlutils`` to handle lp:foo/bar URLs. (Gordon Tyler)
488
* ``bzrlib._c_static_tuple.StaticTuple`` now implements ``__sizeof__``, so
489
that ``sys.getsizeof`` and other memory analysis tools will report more
490
accurate results. (Andrew Bennetts)
492
* The symbol_versioning module can now cleanup after itself -
493
``suppress_deprecation_warnings`` now returns a cleanup function.
499
* Add ``bzrlib.tests.fixtures`` to hold code for setting up objects
500
to test. (Martin Pool)
502
* ``test_import_tariff`` now respects BZR_PLUGINS_AT and BZR_PLUGINS_DISABLE.
503
(Vincent Ladeuil, #595587)
511
This third beta in the 2.2 series brings with it all the goodness of 2.1.2
512
and 2.0.6 (though it preceeds 2.0.6 slightly). Of particular note for
513
users are compatibility fixes with bzr 1.5 and below servers, a hopeful
514
end to the EINTR errors caused by SIGWINCH interactions, a shiny new
515
bash completion script and bzr will no longer guess at identity details -
516
it was too unreliable in reality. Use ``bzr whoami`` on every new install.
517
For developers we have some API changes which may impact plugins as well
518
as a bunch of our regular improvements to internal clarity and test
524
* An API break has been made to the lock_write method of ``Branch`` and
525
``Repository`` objects; they now return ``branch.BranchWriteLockResult``
526
and ``repository.RepositoryWriteLockResult`` objects. This makes
527
changing the API in future easier and permits some cleaner calling code.
528
The lock_read method has also changed from having no defined return
529
value to returning ``LogicalLockResult`` objects.
532
* ``bzr`` does not try to guess the username as ``username@hostname``
533
and requires it to be explictly set. This can be set using ``bzr
534
whoami``. (Parth Malwankar, #549310)
536
* ``bzrlib.commands.Command`` will now raise ValueError during
537
construction if there is no __doc__ set. (Note, this will be reverted in
538
2.2b4) (Robert Collins)
540
* The source tree no longer contains a contrib/zsh/_bzr completion
541
script. The new file contrib/zsh/README suggests alternatives.
542
(Martin von Gagern, #560030)
547
* ``bzr commit`` accepts ``-p`` (for "patch") as a shorter name for
549
(Parth Malwankar, #571467)
551
* ``bzr ignore`` now supports a ``--default-rules`` option that displays
552
the default ignore rules used by bzr. The flag ``--old-default-rules``
553
is no longer supported by ``ignore``.
554
(Parth Malwankar, #538703)
556
* ``bzr pack`` now supports a ``--clean-obsolete-packs`` option that
557
can save disk space by deleting obsolete pack files created during the
559
(Parth Malwankar, #304320)
561
* New command line option ``--authors`` to ``bzr log`` allows users to
562
select which of the apparent authors and committer should be
563
included in the log. Defaults depend on format. (Martin von Gagern, #513322)
565
* Support ``--directory`` option for a number of additional commands:
566
added, annotate, bind, cat, cat-revision, clean-tree, deleted,
567
export, ignore, ignored, lookup-revision, ls, modified, nick,
568
re-sign, unbind, unknowns.
569
(Martin von Gagern, #527878)
571
* The bash_completion plugin from the bzr-bash-completion project has
572
been merged into the tree. It provides a bash-completion command and
573
replaces the outdated ``contrib/bash/bzr`` script with a version
574
using the plugin. (Martin von Gagern, #560030)
576
* A new transport based on GIO (the gnome i/o library) provides access to
577
samba shares, webdav using gio+smb and gio+dav. It is also possible to
578
use gio for some already existing transport methods as gio+file,
585
* Alias information shown by ``bzr help`` is now accurate. This
586
was showing an internal object name for some plugin aliases.
587
(Parth Malwankar, #584650)
589
* ``.bazaar``, ``.bazaar/bazaar.conf`` and ``.bzr.log`` inherit user and
590
group ownership from the containing directory. This allow bzr to work
592
(Martin <gzlist@googlemail.com>, Parth Malwankar, #376388)
594
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
595
support of bzr-externals and scmproj plugins.
596
(Alexander Belchenko, bug #572098)
598
* ``bzr ignore`` will no longer add duplicate patterns to .bzrignore.
599
(Gordon Tyler, #572092)
601
* ``bzr log --exclude-common-ancestry -r X..Y`` displays the revisions that
602
are part of Y ancestry but not part of X ancestry (aka the graph
604
(Vincent Ladeuil, #320119)
606
* ``bzr lp-propose`` which was switched to use production Launchpad API
607
servers a few commits ago has been reverted to use edge: there is a
608
problem with using production which isn't trivially obvious, so we've
609
filed a bug to track it, and until thats fixed will be using edge.
610
(Robert Collins, #583667)
612
* ``bzr rm`` should not refuse to delete directories which contained a file
613
which has been moved elsewhere in the tree after the previous commit.
614
(Marius Kruger, Daniel Watkins, #129880)
616
* ``bzr selftest --parallel=fork`` wait for its children avoiding zombies.
617
(Vincent Ladeuil, #566670)
619
* ``bzr selftest`` should not use ui.note() since it's not unicode safe.
620
(Vincent Ladeuil, #563997)
622
* CommitBuilder refuses to create revisions whose trees have no root.
625
* Do not register a SIGWINCH signal handler, instead just poll for the
626
terminal width as needed. This avoids the "Interrupted System Call"
627
problems that occur on POSIX with all currently released versions of
629
(Andrew Bennetts, #583941)
631
* Don't mention --no-strict when we just issue the warning about unclean trees.
632
(Vincent Ladeuil, #401599)
634
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
636
(Andrew Bennetts, #528041)
638
* Improved progress bar for fetch (2a format only). Bazaar now shows an
639
estimate of the number of records to be fetched vs actually fetched.
640
(Parth Malwankar, #374740, #538868)
642
* Reduce peak memory by one copy of compressed text.
643
(John Arbash Meinel, #566940)
645
* ``RemoteBranch.lock_write`` raises ``ReadOnlyError`` if called during a
646
read lock, rather than causing an ``AttributeError``.
647
(Andrew Bennetts, Danilo Segan, #582781)
649
* Selftest was failing with testtools 0.9.3, which caused an
650
AssertionError raised from a cleanUp to be reported as a Failure, not an
651
Error, breaking on of our test hygiene tests.
652
(Robert Collins, Vincent Ladeuil).
654
* ``set_user_option`` with a dict on remote branches no longer fails with
655
an AttributeError. There is a new ``Branch.set_config_option_dict`` RPC
656
to support this efficiently.
657
(Andrew Bennetts, #430382)
659
* Show the filenames when a file rename fails so that the error will be
661
(Martin Pool, #491763)
663
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
664
(John Arbash Meinel, #582656)
666
* Unicode characters in aliases are now handled correctly and do not cause
667
UnicodeEncodeError exception. (Parth Malwankar, #529930)
669
* Unicode commit messages that are the same as a file name no longer cause
670
UnicodeEncodeError. ``ui.text.show_warning`` now handles unicode
672
(Parth Malwankar, #563646)
674
* When passing a file to ``UTF8DirReader`` make sure to close the current
675
directory file handle after the chdir fails. Otherwise when passing many
676
filenames into a command line ``bzr status`` we would leak descriptors.
677
(John Arbash Meinel, #583486)
682
* ``append_revisions_only`` will now be interpreted as a boolean and a
683
warning emitted if illegal values are used. Note that for projects
684
that needs to maintain compatibility with previsous bzr versions,
685
only 'True' and 'False' strings must be used (previous versions of
686
bzr will interpret all strings differing from 'True'
687
(case-sensitive) as false.
688
(Brian de Alwis, Vincent Ladeuil)
690
* ``bzr ls`` now supports short options for existing long options.
691
``-k/--kind``, ``-i/--ignored``, ``-u/--unknown`` and ``-0/--null``.
692
(Parth Malwankar, #181124)
694
* ``Config.get_user_option_as_bool`` will now warn if a value cannot
695
be interpreted as a boolean.
698
* The all-in-one Windows installer will now be built with docstrings stripped
699
from the library zip, reducing the size and slightly improving cold startup
700
time. Bundled plugins are unchanged for the moment, but if adding other new
701
plugins to an all-in-one installation, ensure they are compiled and
702
installed with -O1 or help may not work. (Martin [gz])
707
* Added ``bzrlib.merge.PerFileMerger``, a more convenient way to write
708
some kinds of ``merge_file_content`` hook functions.
711
* `BzrDir`, `Branch`, `Repository` and `WorkingTree` now all support `user_url`,
712
`user_transport`, `control_url` and `control_transport` members pointing
713
respectively to the directory containing the ``.bzr`` control directory,
714
and to the directory within ``.bzr`` used for the particular component.
715
All of them inherit from `ControlComponent` which provides default
719
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
720
expected to return an object which can be used to unlock them. This reduces
721
duplicate code when using cleanups. The previous 'tokens's returned by
722
``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
723
on the result of the lock_write. ``repository.RepositoryWriteLockResult``
724
and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
726
* ``Repository.refresh_data`` may now be called in a write group on
727
pack-based repositories. Older repositories will still raise an error
728
in this case. Subclasses of ``Repository`` can still override
729
``Repository._refresh_data``, but are now responsible for raising
730
``bzrlib.repository.IsInWriteGroupError`` if they do not support
731
``refresh_data`` during a write group.
732
(Andrew Bennetts, #574236)
737
* ``chk_map._bytes_to_text_key`` is now an optimized function to extract
738
the (file-id, revision-id) key from a CHKInventory entry. This can
739
potentially shave 5-10% time off during a large fetch. Related to bug
740
#562666. (John Arbash Meinel)
742
* ``log._get_info_for_log_files`` now takes an add_cleanup callable.
745
* ``_remember_remote_is_before`` no longer raises AssertionError when
746
suboptimal network behaviour is noticed; instead it just mutters to the
747
log file (and warns the user if they have set the ``hpss`` debug flag).
748
This was causing unnecessary aborts for performance bugs that are minor
750
(Andrew Bennetts, #528041)
752
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
753
files loaded from disk. To ensure docstrings needed for help are never
754
stripped, the prefix ``__doc__ =`` should now be used.
755
(Martin <gzlist@googlemail.com>)
757
* No longer require zlib headers to build extensions, and remove the need
758
for seperate copy of zlib library on windows.
759
(John Arbash Meinel, Martin <gzlist@googlemail.com>, #566923)
764
* Added ``bzrlib.tests.matchers`` as a place to put matchers, along with
765
our first in-tree matcher. See the module docstring for details.
768
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
769
(Gordon Tyler, #551332)
771
* Workaround ``Crypto.Random`` check leading to spurious test
772
failures on Lucid, FreeBSD and gentoo.
773
(Vincent Ladeuil, #528436)
775
* New class ``ExecutableFeature`` for checking the availability of
776
executables on the ``PATH``. Migrated from bash_completion plugin.
785
This is a somewhat early second beta of the 2.2 series, to fix a python2.4
786
incompatibility in the 2.2b1 release. It also includes a swag of
787
performance, usability and correctness improvements: test feedback on all
788
of these would be welcome.
794
* ``bzr diff`` now supports a --format option, which can be used to
795
select alternative diff formats. (Jelmer Vernooij, #555994)
800
* ``bzr dpush``, ``bzr push`` and ``bzr send`` will now issue a warning
801
instead of failing when dirty trees are involved. The corresponding
802
``dpush_strict``, ``push_strict`` and ``send_strict`` should be set to
803
True explicitly to get the previous behaviour.
804
(Vincent Ladeuil, #519319)
806
* ``bzr export`` to tar file does not fail if any parent directory
807
contains unicode characters. This works around upstream Python bug
808
http://bugs.python.org/issue8396 .
809
(Parth Malwankar, #413406)
811
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
812
(Aaron Bentley, #559436)
814
* ``bzr update`` when a pending merge in the working tree has been merged
815
into the master branch will no longer claim that old commits have become
816
pending merges. (Robert Collins, #562079)
818
* ``bzrlib.mutabletree.MutableTree.commit`` will now support a passed in
819
config as in previous versions of bzrlib. (Robert Collins)
821
* Fix glitch in the warning about unclean trees display.
822
(Vincent Ladeuil, #562665)
824
* Fixed Python2.4 incompatibilities in the bzr2.2b1 source tarball.
827
* Help messages generated by ``RegistryOption.from_kwargs`` list the
828
switches in alphabetical order, rather than in an undefined order.
829
(Martin von Gagern, #559409)
831
* Make sure the ``ExecutablePath`` and ``InterpreterPath`` are set in
832
Apport crash reports, to avoid "This problem report applies to a program
833
which is not installed any more" error.
834
(Martin Pool, James Westby, #528114)
836
* Reset ``siginterrupt`` flag to False every time we handle a signal
837
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
838
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
839
errors compared to registering ``signal.signal`` directly.
842
* When invoked with a range revision, ``bzr log`` doesn't show revisions
843
that are not part of the Y revisions ancestry anymore when invoked with
845
(Vincent Ladeuil, #474807)
847
* Properly handle ``param_name`` attribute for ``ListOption``.
848
(Martin von Gagern, #387117)
853
* ``bzr commit`` will prompt before using a commit message that was
854
generated by a template and not edited by the user.
855
(Robert Collins, #530265)
857
* ``bzr diff`` read-locks the trees and branches only once, saving about
858
10-20ms on ``bzr diff`` in a bzr.dev tree.
861
* ``bzr missing`` read-locks the branches only once.
864
* ``bzr pull`` locks the branches and tree only once.
867
* Index lookups in pack repositories search recently hit pack files first.
868
In repositories with many pack files this can greatly reduce the
869
number of files accessed, the number of bytes read, and the number of
870
read calls. An incremental pull via plain HTTP takes half the time and
871
bytes for a moderately large repository. (Andrew Bennetts)
873
* Index lookups only re-order the indexes when the hit files aren't
874
already first. Reduces the cost of reordering
875
(John Arbash Meinel, #562429)
877
* Less code is loaded at startup. (Cold-cache start time is about 10-20%
879
(Martin Pool, #553017)
884
* ``bzrlib.diff.get_trees_and_branches_to_diff`` is deprecated. Use
885
``get_trees_and_branches_to_diff_locked`` instead.
888
* ``TreeTransform.commit`` supports the full set of commit parameters, and
889
auto-determines branch nick if not supplied. (Aaron Bentley)
894
* ``bzrlib.commands.Command.run_direct`` is no longer needed - the pre
895
2.1 method of calling run() to perform testing or direct use via the API
896
is now possible again. As part of this, the _operation attribute on
897
Command is now transient and only exists for the duration of ``run()``.
905
This is the first beta of the 2.2 series, leading up to a 2.2.0
906
release in July or August. Beta releases are suitable for everyday use
907
but may cause some incompatibilities with plugins. Some plugins may need
908
small updates to work with 2.2b1.
910
2.2b1 includes some changes to make merge conflicts easier to understand
911
and resolve. It also removes some old unnecessary code, and loads
912
somewhat less code at startup. It starts adding a common infrastructure
913
for dealing with colocated named branches, which can be implemented in
914
various ways in either bzr native or foreign formats. On Ubuntu and
915
other platforms with the apport bug-reporting library, there's an easier
916
path to report problems with bzr. We plan to continue with these themes
917
through the 2.2 series.
919
Over thirty bugs have been fixed, including in the log command, exporting
920
to tarballs, restarting interrupted system calls, portability of compiled
921
extensions, making backups during upgrade, and locking on ftp.
926
* BTreeGraphIndex can now take an offset to indicate that the data starts
927
somewhere other than then beginning of the file. (John Arbash Meinel)
929
* Deleted very old hidden commands ``versionedfile-list``,
930
``weave-plan-merge``, ``weave-merge-text``.
933
* ``Repository.get_inventory_sha1()`` and ``Repository.get_revision_xml()``
934
have been removed. (Jelmer Vernooij)
936
* ``Repository.get_revision_inventory()`` has been removed in favor of
937
``Repository.get_inventory()``. (Jelmer Vernooij)
939
* All test servers have been moved out of the bzrlib.transport hierarchy to
940
bzrlib.tests.test_server *except* for MemoryServer, ChrootServer and
941
PathFilteringServer. ``bzrlib`` users may encounter test failures that can
942
be fixed by updating the related imports from ``bzrlib.transport.xxx`` to
943
``bzrlib.tests.test_server``.
946
* ``BranchReferenceFormat.initialize()`` now takes an optional name argument
947
as its second parameter, for consistency with the initialize() method of
948
other formats. (Jelmer Vernooij)
953
* Added ``bzr remove-branch`` command that can remove a local or remote
954
branch. (Jelmer Vernooij, #276295)
956
* ``bzr export`` now takes an optional argument ``--per-file-timestamps``
957
to set file mtimes to the last timestamp of the last revision in which
958
they were changed rather than the current time. (Jelmer Vernooij)
960
* If the Apport crash-reporting tool is available, bzr crashes are now
961
stored into the ``/var/crash`` apport spool directory, and the user is
962
invited to report them to the developers from there, either
963
automatically or by running ``apport-bug``. No information is sent
964
without specific permission from the user. (Martin Pool, #515052)
966
* Parsing of command lines, for example in ``diff --using``, no longer
967
treats backslash as an escape character on Windows.
968
(Gordon Tyler, #392428)
970
* Plugins can be disabled by defining ``BZR_DISABLE_PLUGINS`` as
971
a list of plugin names separated by ':' (';' on windows).
972
(Vincent Ladeuil, #411413)
974
* Plugins can be loaded from arbitrary locations by defining
975
``BZR_PLUGINS_AT`` as a list of name@path separated by ':' (';' on
976
windows). This takes precedence over ``BZR_PLUGIN_PATH`` for the
977
specified plugins. This is targeted at plugin developers for punctual
978
needs and *not* intended to replace ``BZR_PLUGIN_PATH``.
979
(Vincent Ladeuil, #82693)
981
* Tag names can now be determined automatically by ``automatic_tag_name``
982
hooks on ``Branch`` if they are not specified on the command line.
985
* Tree-shape conflicts can be resolved by providing ``--take-this`` and
986
``--take-other`` to the ``bzr resolve`` command. Just marking the conflict
987
as resolved is still accessible via the ``--done`` default action.
990
* Merges can be proposed on Launchpad with the new lp-propose-merge command.
991
(Aaron Bentley, Jonathan Lange)
996
* Added docstring for ``Tree.iter_changes``
997
(John Arbash Meinel, #304182)
999
* Allow additional arguments to
1000
``RemoteRepository.add_inventory_by_delta()``. (Jelmer Vernooij, #532631)
1002
* Allow exporting a single file using ``bzr export``.
1003
(Michal Junák, #511987)
1005
* Allow syscalls to automatically restart when ``TextUIFactory``'s
1006
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
1007
IO, which are often poorly handled by Python's libraries and parts of
1008
bzrlib. (Andrew Bennetts, #496813)
1010
* Avoid infinite recursion when probing for apport.
1011
(Vincent Ladeuil, #516934)
1013
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1014
(Martin Pool, #331095)
1016
* Avoid truncating svn URLs.
1017
(Martin Pool, Martin von Gagern, #545185)
1019
* ``bzr add`` will not add conflict related files unless explicitly required.
1020
(Vincent Ladeuil, #322767, #414589)
1022
* ``bzr dump-btree`` now works on ``*.cix`` and ``*.six`` files. Those
1023
indices do not have reference lists, so ``dump-btree`` will simply show
1024
``None`` instead. (Andrew Bennetts, #488607)
1026
* ``bzr help`` will no longer trigger the get_missing_command hook when
1027
doing a topic lookup. This avoids prompting (like 'no command plugins/loom,
1028
did you mean log?') when getting help. In future we may trigger the hook
1029
deliberately when no help topics match from any help index.
1030
(Robert Collins, #396261)
1032
* ``bzr log -n0 -r..A.B.C`` should not crash but just consider the None
1033
revspec as representing the first revision of the branch.
1034
(Vincent Ladeuil, #519862)
1036
* ``bzr remove-tree`` can now remove multiple working trees.
1037
(Jared Hance, Andrew Bennetts, #253137)
1039
* ``bzr resolve --take-this`` and ``--take-other`` now correctly renames
1040
the kept file on content conflicts where one side deleted the file.
1041
(Vincent Ladeuil, #529968)
1043
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
1044
permissions as ``.bzr`` directory on a POSIX OS.
1045
(Parth Malwankar, #262450)
1047
* ``bzr upgrade`` now names backup directory as ``backup.bzr.~N~`` instead
1048
of ``backup.bzr``. This directory is ignored by bzr commands such as
1050
(Parth Malwankar, #335033, #300001)
1052
* Cope with non-utf8 characters inside ``.bzrignore``.
1053
(Jason Spashett, #183504)
1055
* Correctly interpret "451 Rename/move failure: Directory not empty" from
1056
ftp servers while trying to take a lock.
1057
(Martin Pool, #528722)
1059
* DirStateRevisionTree.kind() was returning wrong result when 'kind'
1060
changes occured between the workingtree and one of its parents.
1061
(Vincent Ladeuil, #535547)
1063
* Fix ``log`` to better check ancestors even if merged revisions are involved.
1064
(Vincent Ladeuil, #476293)
1066
* Loading a plugin from a given path with ``BZR_PLUGINS_AT`` doesn't depend
1067
on os.lisdir() order and is now reliable.
1068
(Vincent Ladeuil, #552922).
1070
* Many IO operations that returned ``EINTR`` were retried even if it
1071
wasn't safe to do so via careless use of ``until_no_eintr``. Bazaar now
1072
only retries operations that are safe to retry, and in some cases has
1073
switched to operations that can be retried (e.g. ``sock.send`` rather than
1075
(Andrew Bennetts, Martin <gzlist@googlemail.com>, #496813)
1077
* Path conflicts now support --take-this and --take-other even when a
1078
deletion is involved.
1079
(Vincent Ladeuil, #531967)
1081
* Network transfer amounts and rates are now displayed in SI units according
1082
to the Ubuntu Units Policy <https://wiki.ubuntu.com/UnitsPolicy>.
1083
(Gordon Tyler, #514399)
1085
* Support kind markers for socket and fifo filesystem objects. This
1086
prevents ``bzr status --short`` from crashing when those files are
1087
present. (John Arbash Meinel, #303275)
1089
* ``bzr mkdir DIR`` will not create DIR unless DIR's parent is a versioned
1090
directory. (Parth Malwankar, #138600)
1092
* SSH child processes will now ignore SIGQUIT on nix systems so breaking into
1093
the debugger won't kill the session.
1094
(Martin <gzlist@googlemail.com>, #162502)
1096
* Tolerate patches with leading noise in ``bzr-handle-patch``.
1097
(Toshio Kuratomi, Martin Pool, #502076)
1099
* ``update -r`` now supports updating to revisions that are not on
1100
mainline (i.e. it supports dotted revisions).
1101
(Parth Malwankar, #517800)
1103
* Use first apparent author not committer in GNU Changelog format.
1104
(Martin von Gagern, #513322)
1109
* ``bzrlib.merge_directive._BaseMergeDirective`` has been renamed to
1110
``bzrlib.merge_directive.BaseMergeDirective`` and is now public.
1113
* ``BranchFormat.initialize`` now takes an optional ``name`` of the colocated
1114
branch to create. (Jelmer Vernooij)
1116
* ``BzrDir.get_branch_transport`` now takes an optional ``name`` of the
1117
colocated branch to open. (Jelmer Vernooij)
1119
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
1120
can set a signal handler and call ``signal.siginterrupt(signum,
1121
False)`` for it, if the platform and Python version supports it.
1122
(Andrew Bennetts, #496813)
1124
* New ``bzrlib.initialize`` is recommended for programs using bzrlib to
1125
run when starting up; it sets up several things that previously needed
1126
to be done separately.
1127
(Martin Pool, #507710)
1129
* Exporters now support a ``per_file_timestamps`` argument to write out the
1130
timestamp of the commit in which a file revision was introduced.
1133
* New method ``BzrDir.list_branches()`` that returns a sequence of branches
1134
present in a control directory. (Jelmer Vernooij)
1136
* New method ``Repository.get_known_graph_ancestry()``.
1137
(Jelmer Vernooij, #495502)
1139
* New transport methods ``readlink``, ``symlink`` and ``hardlink``.
1142
* Remove unused ``CommandFailed`` exception.
1148
* ``bzrlib.branchbuilder.BranchBuilder.build_snapshot`` now accepts a
1149
``message_callback`` in the same way that commit does. (Robert Collins)
1151
* ``bzrlib.builtins.Commit.run`` raises ``bzrlib.errors.BoundBranchOutOfDate``
1152
rather than ``bzrlib.errors.BzrCommandError`` when the bound branch is out
1153
of date. (Gary van der Merwe)
1155
* ``bzrlib.commands.run_bzr`` is more extensible: callers can supply the
1156
functions to load or disable plugins if they wish to use a different
1157
plugin mechanism; the --help, --version and no-command name code paths
1158
now use the generic pluggable command lookup infrastructure.
1161
* ``bzrlib.errors.BoundBranchOutOfDate`` has a new field ``extra_help``
1162
which can be set to add extra help to the error. (Gary van der Merwe)
1164
* New method ``Branch.automatic_tag_name`` that can be used to find the
1165
tag name for a particular revision automatically. (Jelmer Vernooij)
1167
* The methods ``BzrDir.create_branch()``, ``BzrDir.destroy_branch()`` and
1168
``BzrDir.open_branch()`` now take an optional ``name`` argument.
1174
* bzr now has a ``.testr.conf`` file in its source tree configured
1175
appropriately for running tests with Testrepository
1176
(``https://launchpad.net/testrepository``). (Robert Collins)
1178
* Documentation about testing with ``subunit`` has been tweaked.
1181
* Known failures has been added for resolve --take-other on ParentLoop
1182
conflicts. This reflects bug #537956 without fixing it.
1185
* New ``bzrlib.tests.test_import_tariff`` can make assertions about what
1186
Python modules are loaded, to guard against startup time or library
1187
dependency regressions.
1190
* PQM will now run with subunit output. To analyze a PQM error use
1191
tribunal, or cat log | subunit-filter | subunit2pyunit. (Robert Collins)
1193
* Stop sending apport crash files to ``.cache`` in the directory from
1194
which ``bzr selftest`` was run. (Martin Pool, #422350)
1196
* Tests no longer fail if "close() called during concurrent
1197
operation on the same file object" occurs when closing the log file
1198
(which can happen if a thread tries to write to the log file at the
1199
wrong moment). An warning will be written to ``stderr`` when this
1200
happens, and another warning will be written if the log file could not
1201
be closed after retrying 100 times. (Andrew Bennetts, #531746)
