:2.2.3: NOT RELEASED YET
16
* Launchpad has announced that the ``edge.launchpad.net`` instance is
17
deprecated and may be shut down in the future
18
<http://blog.launchpad.net/general/edge-is-deprecated>. Bazaar has therefore
19
been updated in this release to talk to the main (``launchpad.net``) servers,
20
rather than the ``edge`` ones. (Vincent Ladeuil, #583667)
28
* Avoid UnicodeDecodeError in ``bzr add`` with multiple files under a non-ascii
29
path on windows from symlink support addition. (Martin [gz], #686611)
31
* Don't probe for a repository from within ``NotBranchError.__repr__``,
32
because this can cause knock-on errors at awkward times.
33
(Andrew Bennetts, #687653)
35
* ``https`` access works again with recent versions of python2.7.
36
(Vincent Ladeuil, #693880)
38
* RevisionTree.is_executable no longer returns None for directories and
39
symlinks. Instead, it returns False, like other Trees and methods.
40
(Aaron Bentley, #681885)
62
This is a bugfix release. None of these bugfixes are critical, but upgrading
63
is recommended for all users on earlier 2.2 releases.
71
* ``bzr resolve --take-other <file>`` will not crash anymore if ``<file>``
72
is involved in a text conflict (but the conflict is still not
73
resolved). (Vincent Ladeuil, #646961)
75
* Commit in a bound branch or heavyweight checkout now propagates tags
76
(e.g. from a merge) to the master branch (and informs the user if there
77
is a conflict). (Andrew Bennetts, #603395)
79
* Correctly set the Content-Type header when HTTP POSTing to comply
80
with stricter web frameworks. (Vincent Ladeuil, #665100)
82
* ``NotBranchError`` no longer allows errors from calling
83
``bzrdir.open_repository()`` to propagate. This is unhelpful at best,
84
and at worst can trigger infinite loops in callers. (Andrew Bennetts)
86
* Skip tests that needs a bzr source tree when there isn't one. This is
87
needed to succesfully run the test suite for installed versions.
88
(Vincent Ladeuil, #644855).
90
* Skip the tests that requires respecting the chmod bits when running as
91
root. Including the one that wasn't present in 2.1.
92
(Vincent Ladeuil, #646133)
94
* Using bzr with `lp:` URLs behind an HTTP proxy should work.
95
(Robert Collins, #558343)
97
* Windows installers no longer requires the Microsoft vcredist to be
99
(Martin [gz], Gary van der Merwe, #632465)
101
* Close leaked socket to SSH subprocesses, which caused dput sftp uploads
102
to hang. (Max Bowsher, #659590)
107
* Add ``tests/ssl_certs/ca.crt`` to the required test files list. Test
108
involving the pycurl https test server fail otherwise when running
109
selftest from an installed version. (Vincent Ladeuil, #651706)
111
* Fix tests that failed when run under ``LANG=C``.
112
(Andrew Bennetts, #632387)
120
This is a bugfix release which also includes bugfixes from 2.0.6 and
121
2.1.3. None are critical, but upgrading is recommended for all users on
122
earlier 2.2 releases.
127
* Additional merges after an unrelated branch has been merged with its
128
history no longer crash when deleted files are involved.
129
(Vincent Ladeuil, John Arbash Meinel, #375898)
131
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
132
previously-unversioned directory within the tree: the directory is
133
marked versioned too.
134
(Martin Pool, #192859)
136
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
137
target of the symlink.
138
(Martin Pool, John Arbash Meinel, #128562)
140
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
141
permissions as ``.bzr`` directory on a POSIX OS.
142
(Parth Malwankar, #262450)
144
* CommitBuilder now uses the committer instead of _config.username to generate
145
the revision-id. (Aaron Bentley, #614404)
147
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
148
way which should help avoid problems with concurrent writers.
149
(Vincent Ladeuil, #525571)
151
* Cope with Microsoft FTP server that returns reply '250 Directory
152
created' when mkdir succeeds. (Martin Pool, #224373)
154
* Don't traceback trying to unversion children files of an already
155
unversioned directory. (Vincent Ladeuil, #494221)
157
* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
158
contains only NUL bytes). Instead warn the user, and allow ``bzr
159
break-lock`` to remove it. (Andrew Bennetts, #619872)
161
* Fix ``AttributeError on parent.children`` when adding a file under a
162
directory that was a symlink in the previous commit.
163
(Martin Pool, #192859)
165
* Fix ``AttributeError: 'NoneType' object has no attribute 'close'`` in
166
``_close_ssh_proc`` when using ``bzr+ssh://``. This was causing
167
connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on
168
stderr in some other circumstances. (Andrew Bennetts, #633745)
170
* Only call ``setlocale`` in the bzr startup script on posix systems. This
171
avoids an issue with the newer windows C runtimes used by Python 2.6 and
172
later which can mangle bytestrings printed to the console.
173
(Martin [gz], #631350)
175
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
176
which can result in "missing referenced chk root keys" errors when
177
fetching from repositories with affected revisions.
178
(Andrew Bennetts, #522637)
180
* Raise ValueError instead of a string exception.
181
(John Arbash Meinel, #586926)
183
* Reduce peak memory by one copy of compressed text.
184
(John Arbash Meinel, #566940)
186
* Repositories accessed via a smart server now reject being stacked on a
187
repository in an incompatible format, as is the case when accessing them
188
via other methods. This was causing fetches from those repositories via
189
a smart server (e.g. using ``bzr branch``) to receive invalid data.
190
(Andrew Bennetts, #562380)
192
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
193
error. This error was caused by 2.0 not being updated when upstream
194
python merged the end of run patch, which chose ``stopTestRun`` rather than
195
``done``. (Robert Collins, #571437)
197
* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``
198
being thrown from ``xml_serializer`` on certain cElementTree setups.
199
(Martin [gz], #254278)
201
* Upgrading or fetching from a non-rich-root repository to a rich-root
202
repository (e.g. from pack-0.92 to 2a) no longer fails with
203
``'Inter1and2Helper' object has no attribute 'source_repo'``. This was
204
a regression from Bazaar 2.1. (Andrew Bennetts, #636930)
206
* When passing a file to ``UTF8DirReader`` make sure to close the current
207
directory file handle after the chdir fails. Otherwise when passing many
208
filenames into a command line ``bzr status`` we would leak descriptors.
209
(John Arbash Meinel, #583486)
214
* Fix a lot of references in the docs to the old http://bazaar-vcs.org to
215
the new http://bazaar.canonical.com or http://wiki.bazaar.canonical.com
216
(John Arbash Meinel, #617503)
221
* Remove used and broken code path in ``BranchInitHookParams.__repr__``.
227
* ``build_tree_contents`` can create symlinks.
228
(Martin Pool, John Arbash Meinel)
230
* Tracebacks from a parameterized test are no longer reported against every
231
parameterization of that test. This was done by adding a hack to
232
``bzrlib.tests.clone_test`` so that it no longer causes
233
testtools.TestCase instances to share a details dict.
234
(Andrew Bennetts, #625574)
242
This release marks the start of another long-term-stable series. From
243
here, we will only make bugfix releases on the 2.2 series (2.2.1, etc),
244
while 2.3 will become our new development series. The 2.0 and 2.1 series
245
will also continue to get bugfixes. (Currently 2.0 is planned to be
246
supported for another 6 months.)
248
This is primarily a bugfix and polish release over the 2.1 series, with
249
a large number of bugs fixed (>120), and some performance improvements.
251
There are some compatibility changes in this release. For users of bzrlib
252
as a library, we now request that they call ``bzrlib.initialize`` and use
253
the returned context manager appropriately. For commandline users we no
254
longer guess user identity for ``bzr commit``, users must specify their
255
identity using ``bzr whoami`` (you don't need to specify your identity for
256
readonly operations).
258
Users are encouraged to upgrade from the other stable series.
263
* BzrError subclasses no longer support the name "message" to be used
264
as an argument for __init__ or in _fmt format specification as this
265
breaks in some Python versions. errors.LockError.__init__ argument
266
is now named "msg" instead of earlier "message".
267
(Parth Malwankar, #603461)
269
* The old ``bzr selftest --benchmark`` option has been removed.
270
<https://launchpad.net/bzr-usertest> is an actively-maintained
271
macrobenchmark suite.
277
* ``bzr ignore PATTERNS`` exits with error if a bad pattern is supplied.
278
``InvalidPattern`` exception error message now shows faulting
280
(Parth Malwankar #300062)
282
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
283
way which should help avoid problems with concurrent writers.
284
(Vincent Ladeuil, #525571)
286
* Don't traceback trying to unversion children files of an already
287
unversioned directory. (Vincent Ladeuil, #494221)
289
* ``HTTP/1.1`` test servers now set a ``Content-Length`` header to comply
290
with pedantic ``HTTP/1.1`` clients. (Vincent Ladeuil, #568421)
292
* Progress bars prefer to truncate the text message rather than the
293
counters. The spinner is shown between the network transfer indicator
294
and the progress message. Progress bars are correctly cleared off when
295
they finish. (Martin Pool, #611127)
297
* Recursive binding for checkouts is now detected by bzr. A clear error
298
message is shown to the user. (Parth Malwankar, #405192)
303
* Add ``bzrlib.merge.MergeIntoMerger``, which can merge part or all of a
304
tree, and works with unrelated branches. (Andrew Bennetts)
306
* Add py2exe windows target ``bzrw.exe``. This allow for starting a Bazaar
307
GUI with out have a console open in the background.
308
(Gary van der Merwe, #433781)
313
* ``bzr help patterns`` now explains case insensitive patterns and
314
points to Python regular expression documentation.
315
(Parth Malwankar, #594386)
320
* Delete ``ProgressTask.note``, which was deprecated in 2.1.
325
* Unit test added to ensure that "message" is not uses as a format variable
326
name in BzrError subclasses as this conflicts with some Python versions.
327
(Parth Malwankar, #603461)
332
:Codename: Monkey Magic
336
This fourth and final beta in the 2.2 series now stabilizes the internal
337
APIs. Plugin authors are recommended to ensure their releases are
338
compatible, so that 2.2rc1 can be a true release candidate, containing
339
stable and compatible plugin versions.
341
For users of bzrlib as a library, one of the primary changes is to request
342
that they call ``bzrlib.initialize`` and use the returned context manager
345
Better interaction with ``bzr-loom`` to make sure branching from a loom
346
even over a smart server still yields a local loom. Not to mention lots of
352
* bzrlib library users now need to call ``__enter__`` and ``__exit__`` on
353
the result of ``bzrlib.initialize``. This change was made when fixing
354
the bad habit recent bzr versions have had of leaving progress bars
355
behind on the screen. That required calling another function before
356
exiting the program, and it made sense to provide a full context
357
manager at the same time. (Robert Collins)
359
* The ``bzr`` front end now requires a ``bzrlib.ui.ui_factory`` which is a
360
context manager in the Python 2.5 and above sense. The bzrlib base class
361
is such a manager, but third party UI factories which do not derive from
362
``bzrlib.ui.UIFactory`` will be incompatible with the command line front
365
* URLs like ``foo:bar/baz`` are now always parsed as a URL with scheme "foo"
366
and path "bar/baz", even if bzr does not recognize "foo" as a known URL
367
scheme. Previously these URLs would be treated as local paths.
374
* Support ``--directory`` option for a number of additional commands:
375
conflicts, merge-directive, missing, resolve, shelve, switch,
376
unshelve, whoami. (Martin von Gagern, #527878)
381
* ``bzr branch`` to a new repository with a default stacking policy no
382
longer transfers the full history unnecessarily.
383
(Andrew Bennetts, #597942)
385
* ``bzr init`` does not recursively scan directory contents anymore
386
leading to faster init for directories with existing content.
387
(Martin [gz], Parth Malwankar, #501307)
389
* ``bzr log --exclude-common-ancestry`` is now taken into account for
390
linear ancetries. (Vincent Ladeuil, #575631)
392
* ``bzr log -r branch:REMOTE`` can now properly log the remote branch,
393
rather than trying to fetch the data locally and failing because of a
394
readonly error. (Martin von Gagern, #149270)
396
* ``bzr pull`` now works when a lp: URL is explicitly defined as the parent
397
or pull location in locations.conf or branch.conf.
398
(Gordon Tyler, #534787)
400
* ``bzr reconfigure --unstacked`` now works with branches accessed via a
401
smart server. (Andrew Bennetts, #551525)
403
* ``BzrDir.find_branches`` should ignore branches with missing repositories.
404
(Marius Kruger, Robert Collins)
406
* ``BzrDir.find_bzrdirs`` should ignore dirs that raises PermissionDenied.
407
(Marius Kruger, Robert Collins)
409
* Ensure that wrong path specifications in ``BZR_PLUGINS_AT`` display
410
proper error messages. (Vincent Ladeuil, #591215)
412
* Explicitly removing ``--profile-imports`` option from parsed command-line
413
arguments on Windows, because bzr script does the same.
414
(Alexander Belchenko, #588277)
416
* Fetching was slightly confused about the best code to use and was
417
using a new code path for all branches, resulting in more lookups than
418
necessary on old branches. (Robert Collins, #593515)
420
* Final fix for 'no help for command' issue. We now show a clean message
421
when a command has no help, document how to set help more clearly, and
422
test that all commands available to the test suite have help.
423
(Robert Collins, #177500)
425
* Invalid patterns supplied to ``Globster`` or ``lazy_regex`` now raise
426
``InvalidPattern`` exception showing clear error message to the user.
427
(Parth Malwankar #300062)
429
* Progress output is cleaned up when exiting. (Aaron Bentley)
431
* Raise ValueError instead of a string exception.
432
(John Arbash Meinel, #586926)
434
* Relative imports in plugins are now handled correctly when using
435
BZR_PLUGINS_AT. (Vincent Ladeuil, #588959)
437
* ``ScriptRunner`` now strips off leading indentation from test scripts,
438
which previously caused "SyntaxError: No command for line".
441
* Show unicode filenames in diff headers using terminal encoding.
442
(Alexander Belchenko, Bug #382699)
443
NOTE for Windows users: If user need to save diff to file then user need to
444
change encoding of the terminal to ANSI encoding with command ``chcp XXX``
445
(e.g. ``chcp 1251`` for Russian Windows).
447
* URL displayed for use with ``break-lock`` when smart server sees lock
448
contention are now valid. Default timeout for lock contention retry is
449
now 30 seconds instead of 300 seconds.
450
(Parth Malwankar, #250451)
452
* ``walkdirs`` now raises a useful message when the filenames are not using
453
the filesystem encoding. (Eric Moritz, #488519)
455
* Enable debugging of bzr on windows with pdb and other tools. This was
456
broken because we call GetCommandLineW on windows. The fix adjusts the
457
command line we get to be the same length as sys.argv.
458
(Jason Spashett, Alexander Belchenko, #587868)
463
* Bazaar now reads data from SSH connections more efficiently on platforms
464
that provide the ``socketpair`` function, and when using paramiko.
465
(Andrew Bennetts, #590637)
467
* ``Branch.copy_content_into`` is now a convenience method dispatching to
468
a ``InterBranch`` multi-method. This permits ``bzr-loom`` and other
469
plugins to intercept this even when a ``RemoteBranch`` proxy is in use.
470
(Robert Collins, #201613)
472
* ``Branch`` formats can now be loaded lazily by registering a
473
``MetaDirBranchFormatFactory`` rather than an actual format. This will
474
cause the named format class to be loaded only when an enumeration of
475
formats is needed or when the format string for the object is
476
encountered. (Robert Collins, Jelmer Vernooij)
478
* The encoding that bzr uses to output things other than file content can
479
now be overridden via the output_encoding configuration option.
480
(Martin Pool, #340394)
482
* Use lazy imports in ``bzrlib/merge.py`` so that plugins like ``news_merge``
483
do not cause modules to be loaded unnecessarily just because the plugin
484
registers a merge hook. This improves ``bzr rocks`` time by about 25%
485
in a default installation (with just the core plugins).
491
* Added ``regression`` tag to our tags list. (Robert Collins)
493
* Improved our release checklist to have a bit less churn and leave things
494
ready-to-go for the next action (including other people doing
495
development). (Robert Collins)
497
* Remove obsolete discussion of PQM in documentation about how to
498
contribute to Bazaar. (Martin Pool, #588444)
503
* ``bzrlib.branch.InterBranch._get_branch_formats_to_test`` now returns
504
an iterable of format pairs, rather than just a single pair, permitting
505
InterBranch objects that work with multiple permutations to be
506
comprehensively tested. (Robert Collins)
508
* ``bzrlib.lsprof.profile`` will no longer silently generate bad threaded
509
profiles when concurrent profile requests are made. Instead the profile
510
requests will be serialised. Reentrant requests will now deadlock.
513
* ``bzrlib.knit.KnitSequenceMatcher``, which has been deprecated since
514
2007, has been deleted. Use ``PatienceSequenceMatcher`` from
515
``bzrlib.patiencediff`` instead. (Andrew Bennetts)
517
* ``bzrlib.re_compile_checked`` is now deprecated. Caller should handle
518
``bzrlib.errors.InvalidPattern`` exception thrown by ``re.match`` in
519
case the default error message not suitable for the use case.
522
* ``bzrlib.tests.blackbox.ExternalBase`` is deprecated. It provided only
523
one method ``check_output``, and we now recommend checking command
524
output using ``run_script``. (Martin Pool)
526
* ``bzrlib.transport.ssh.SSHVendor.connect_ssh`` now returns an object
527
that implements the interface of ``bzrlib.transport.ssh.SSHConnection``.
528
Third-party implementations of ``SSHVendor`` may need to be updated
529
accordingly. Similarly, any code using ``SSHConnection`` directly will
530
need to be updated. (Andrew Bennetts)
532
* The constructor of ``bzrilb.smart.medium.SmartSSHClientMedium`` has
533
changed to take an ``SSHParams`` instance (replacing many individual
534
values). (Andrew Bennetts)
539
* ``bzrlib.osutils.get_terminal_encoding`` will now only mutter its
540
selection when explicitly requested; this avoids many duplicate calls
541
being logged when helpers, wrappers and older code that manually calls
542
it are executed it is now logged deliberately by the ui setup code.
545
* Improved ``bzrlib.urlutils`` to handle lp:foo/bar URLs. (Gordon Tyler)
547
* ``bzrlib._c_static_tuple.StaticTuple`` now implements ``__sizeof__``, so
548
that ``sys.getsizeof`` and other memory analysis tools will report more
549
accurate results. (Andrew Bennetts)
551
* The symbol_versioning module can now cleanup after itself -
552
``suppress_deprecation_warnings`` now returns a cleanup function.
558
* Add ``bzrlib.tests.fixtures`` to hold code for setting up objects
559
to test. (Martin Pool)
561
* ``test_import_tariff`` now respects BZR_PLUGINS_AT and BZR_PLUGINS_DISABLE.
562
(Vincent Ladeuil, #595587)
570
This third beta in the 2.2 series brings with it all the goodness of 2.1.2
571
and 2.0.6 (though it preceeds 2.0.6 slightly). Of particular note for
572
users are compatibility fixes with bzr 1.5 and below servers, a hopeful
573
end to the EINTR errors caused by SIGWINCH interactions, a shiny new
574
bash completion script and bzr will no longer guess at identity details -
575
it was too unreliable in reality. Use ``bzr whoami`` on every new install.
576
For developers we have some API changes which may impact plugins as well
577
as a bunch of our regular improvements to internal clarity and test
583
* An API break has been made to the lock_write method of ``Branch`` and
584
``Repository`` objects; they now return ``branch.BranchWriteLockResult``
585
and ``repository.RepositoryWriteLockResult`` objects. This makes
586
changing the API in future easier and permits some cleaner calling code.
587
The lock_read method has also changed from having no defined return
588
value to returning ``LogicalLockResult`` objects.
591
* ``bzr`` does not try to guess the username as ``username@hostname``
592
and requires it to be explictly set. This can be set using ``bzr
593
whoami``. (Parth Malwankar, #549310)
595
* ``bzrlib.commands.Command`` will now raise ValueError during
596
construction if there is no __doc__ set. (Note, this will be reverted in
597
2.2b4) (Robert Collins)
599
* The source tree no longer contains a contrib/zsh/_bzr completion
600
script. The new file contrib/zsh/README suggests alternatives.
601
(Martin von Gagern, #560030)
606
* ``bzr commit`` accepts ``-p`` (for "patch") as a shorter name for
608
(Parth Malwankar, #571467)
610
* ``bzr ignore`` now supports a ``--default-rules`` option that displays
611
the default ignore rules used by bzr. The flag ``--old-default-rules``
612
is no longer supported by ``ignore``.
613
(Parth Malwankar, #538703)
615
* ``bzr pack`` now supports a ``--clean-obsolete-packs`` option that
616
can save disk space by deleting obsolete pack files created during the
618
(Parth Malwankar, #304320)
620
* New command line option ``--authors`` to ``bzr log`` allows users to
621
select which of the apparent authors and committer should be
622
included in the log. Defaults depend on format. (Martin von Gagern, #513322)
624
* Support ``--directory`` option for a number of additional commands:
625
added, annotate, bind, cat, cat-revision, clean-tree, deleted,
626
export, ignore, ignored, lookup-revision, ls, modified, nick,
627
re-sign, unbind, unknowns.
628
(Martin von Gagern, #527878)
630
* The bash_completion plugin from the bzr-bash-completion project has
631
been merged into the tree. It provides a bash-completion command and
632
replaces the outdated ``contrib/bash/bzr`` script with a version
633
using the plugin. (Martin von Gagern, #560030)
635
* A new transport based on GIO (the Gnome I/O library) provides access to
636
Samba shares, WebDAV using gio+smb and gio+dav. It is also possible to
637
use gio for some already existing transport methods as gio+file,
644
* Alias information shown by ``bzr help`` is now accurate. This
645
was showing an internal object name for some plugin aliases.
646
(Parth Malwankar, #584650)
648
* ``.bazaar``, ``.bazaar/bazaar.conf`` and ``.bzr.log`` inherit user and
649
group ownership from the containing directory. This allow bzr to work
651
(Martin <gzlist@googlemail.com>, Parth Malwankar, #376388)
653
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
654
support of bzr-externals and scmproj plugins.
655
(Alexander Belchenko, bug #572098)
657
* ``bzr ignore`` will no longer add duplicate patterns to .bzrignore.
658
(Gordon Tyler, #572092)
660
* ``bzr log --exclude-common-ancestry -r X..Y`` displays the revisions that
661
are part of Y ancestry but not part of X ancestry (aka the graph
663
(Vincent Ladeuil, #320119)
665
* ``bzr lp-propose`` which was switched to use production Launchpad API
666
servers a few commits ago has been reverted to use edge: there is a
667
problem with using production which isn't trivially obvious, so we've
668
filed a bug to track it, and until thats fixed will be using edge.
669
(Robert Collins, #583667)
671
* ``bzr rm`` should not refuse to delete directories which contained a file
672
which has been moved elsewhere in the tree after the previous commit.
673
(Marius Kruger, Daniel Watkins, #129880)
675
* ``bzr selftest --parallel=fork`` wait for its children avoiding zombies.
676
(Vincent Ladeuil, #566670)
678
* ``bzr selftest`` should not use ui.note() since it's not unicode safe.
679
(Vincent Ladeuil, #563997)
681
* CommitBuilder refuses to create revisions whose trees have no root.
684
* Do not register a SIGWINCH signal handler, instead just poll for the
685
terminal width as needed. This avoids the "Interrupted System Call"
686
problems that occur on POSIX with all currently released versions of
688
(Andrew Bennetts, #583941)
690
* Don't mention --no-strict when we just issue the warning about unclean trees.
691
(Vincent Ladeuil, #401599)
693
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
695
(Andrew Bennetts, #528041)
697
* Improved progress bar for fetch (2a format only). Bazaar now shows an
698
estimate of the number of records to be fetched vs actually fetched.
699
(Parth Malwankar, #374740, #538868)
701
* Reduce peak memory by one copy of compressed text.
702
(John Arbash Meinel, #566940)
704
* ``RemoteBranch.lock_write`` raises ``ReadOnlyError`` if called during a
705
read lock, rather than causing an ``AttributeError``.
706
(Andrew Bennetts, Danilo Segan, #582781)
708
* Selftest was failing with testtools 0.9.3, which caused an
709
AssertionError raised from a cleanUp to be reported as a Failure, not an
710
Error, breaking on of our test hygiene tests.
711
(Robert Collins, Vincent Ladeuil).
713
* ``set_user_option`` with a dict on remote branches no longer fails with
714
an AttributeError. There is a new ``Branch.set_config_option_dict`` RPC
715
to support this efficiently.
716
(Andrew Bennetts, #430382)
718
* Show the filenames when a file rename fails so that the error will be
720
(Martin Pool, #491763)
722
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
723
(John Arbash Meinel, #582656)
725
* Unicode characters in aliases are now handled correctly and do not cause
726
UnicodeEncodeError exception. (Parth Malwankar, #529930)
728
* Unicode commit messages that are the same as a file name no longer cause
729
UnicodeEncodeError. ``ui.text.show_warning`` now handles unicode
731
(Parth Malwankar, #563646)
733
* When passing a file to ``UTF8DirReader`` make sure to close the current
734
directory file handle after the chdir fails. Otherwise when passing many
735
filenames into a command line ``bzr status`` we would leak descriptors.
736
(John Arbash Meinel, #583486)
741
* ``append_revisions_only`` will now be interpreted as a boolean and a
742
warning emitted if illegal values are used. Note that for projects
743
that needs to maintain compatibility with previsous bzr versions,
744
only 'True' and 'False' strings must be used (previous versions of
745
bzr will interpret all strings differing from 'True'
746
(case-sensitive) as false.
747
(Brian de Alwis, Vincent Ladeuil)
749
* ``bzr ls`` now supports short options for existing long options.
750
``-k/--kind``, ``-i/--ignored``, ``-u/--unknown`` and ``-0/--null``.
751
(Parth Malwankar, #181124)
753
* ``Config.get_user_option_as_bool`` will now warn if a value cannot
754
be interpreted as a boolean.
757
* The all-in-one Windows installer will now be built with docstrings stripped
758
from the library zip, reducing the size and slightly improving cold startup
759
time. Bundled plugins are unchanged for the moment, but if adding other new
760
plugins to an all-in-one installation, ensure they are compiled and
761
installed with -O1 or help may not work. (Martin [gz])
766
* Added ``bzrlib.merge.PerFileMerger``, a more convenient way to write
767
some kinds of ``merge_file_content`` hook functions.
770
* `BzrDir`, `Branch`, `Repository` and `WorkingTree` now all support `user_url`,
771
`user_transport`, `control_url` and `control_transport` members pointing
772
respectively to the directory containing the ``.bzr`` control directory,
773
and to the directory within ``.bzr`` used for the particular component.
774
All of them inherit from `ControlComponent` which provides default
778
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
779
expected to return an object which can be used to unlock them. This reduces
780
duplicate code when using cleanups. The previous 'tokens's returned by
781
``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
782
on the result of the lock_write. ``repository.RepositoryWriteLockResult``
783
and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
785
* ``Repository.refresh_data`` may now be called in a write group on
786
pack-based repositories. Older repositories will still raise an error
787
in this case. Subclasses of ``Repository`` can still override
788
``Repository._refresh_data``, but are now responsible for raising
789
``bzrlib.repository.IsInWriteGroupError`` if they do not support
790
``refresh_data`` during a write group.
791
(Andrew Bennetts, #574236)
796
* ``chk_map._bytes_to_text_key`` is now an optimized function to extract
797
the (file-id, revision-id) key from a CHKInventory entry. This can
798
potentially shave 5-10% time off during a large fetch. Related to bug
799
#562666. (John Arbash Meinel)
801
* ``log._get_info_for_log_files`` now takes an add_cleanup callable.
804
* ``_remember_remote_is_before`` no longer raises AssertionError when
805
suboptimal network behaviour is noticed; instead it just mutters to the
806
log file (and warns the user if they have set the ``hpss`` debug flag).
807
This was causing unnecessary aborts for performance bugs that are minor
809
(Andrew Bennetts, #528041)
811
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
812
files loaded from disk. To ensure docstrings needed for help are never
813
stripped, the prefix ``__doc__ =`` should now be used.
814
(Martin <gzlist@googlemail.com>)
816
* No longer require zlib headers to build extensions, and remove the need
817
for seperate copy of zlib library on windows.
818
(John Arbash Meinel, Martin <gzlist@googlemail.com>, #566923)
823
* Added ``bzrlib.tests.matchers`` as a place to put matchers, along with
824
our first in-tree matcher. See the module docstring for details.
827
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
828
(Gordon Tyler, #551332)
830
* Workaround ``Crypto.Random`` check leading to spurious test
831
failures on Lucid, FreeBSD and gentoo.
832
(Vincent Ladeuil, #528436)
834
* New class ``ExecutableFeature`` for checking the availability of
835
executables on the ``PATH``. Migrated from bash_completion plugin.
844
This is a somewhat early second beta of the 2.2 series, to fix a python2.4
845
incompatibility in the 2.2b1 release. It also includes a swag of
846
performance, usability and correctness improvements: test feedback on all
847
of these would be welcome.
853
* ``bzr diff`` now supports a --format option, which can be used to
854
select alternative diff formats. (Jelmer Vernooij, #555994)
859
* ``bzr dpush``, ``bzr push`` and ``bzr send`` will now issue a warning
860
instead of failing when dirty trees are involved. The corresponding
861
``dpush_strict``, ``push_strict`` and ``send_strict`` should be set to
862
True explicitly to get the previous behaviour.
863
(Vincent Ladeuil, #519319)
865
* ``bzr export`` to tar file does not fail if any parent directory
866
contains unicode characters. This works around upstream Python bug
867
http://bugs.python.org/issue8396 .
868
(Parth Malwankar, #413406)
870
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
871
(Aaron Bentley, #559436)
873
* ``bzr update`` when a pending merge in the working tree has been merged
874
into the master branch will no longer claim that old commits have become
875
pending merges. (Robert Collins, #562079)
877
* ``bzrlib.mutabletree.MutableTree.commit`` will now support a passed in
878
config as in previous versions of bzrlib. (Robert Collins)
880
* Fix glitch in the warning about unclean trees display.
881
(Vincent Ladeuil, #562665)
883
* Fixed Python2.4 incompatibilities in the bzr2.2b1 source tarball.
886
* Help messages generated by ``RegistryOption.from_kwargs`` list the
887
switches in alphabetical order, rather than in an undefined order.
888
(Martin von Gagern, #559409)
890
* Make sure the ``ExecutablePath`` and ``InterpreterPath`` are set in
891
Apport crash reports, to avoid "This problem report applies to a program
892
which is not installed any more" error.
893
(Martin Pool, James Westby, #528114)
895
* Reset ``siginterrupt`` flag to False every time we handle a signal
896
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
897
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
898
errors compared to registering ``signal.signal`` directly.
901
* When invoked with a range revision, ``bzr log`` doesn't show revisions
902
that are not part of the Y revisions ancestry anymore when invoked with
904
(Vincent Ladeuil, #474807)
906
* Properly handle ``param_name`` attribute for ``ListOption``.
907
(Martin von Gagern, #387117)
912
* ``bzr commit`` will prompt before using a commit message that was
913
generated by a template and not edited by the user.
914
(Robert Collins, #530265)
916
* ``bzr diff`` read-locks the trees and branches only once, saving about
917
10-20ms on ``bzr diff`` in a bzr.dev tree.
920
* ``bzr missing`` read-locks the branches only once.
923
* ``bzr pull`` locks the branches and tree only once.
926
* Index lookups in pack repositories search recently hit pack files first.
927
In repositories with many pack files this can greatly reduce the
928
number of files accessed, the number of bytes read, and the number of
929
read calls. An incremental pull via plain HTTP takes half the time and
930
bytes for a moderately large repository. (Andrew Bennetts)
932
* Index lookups only re-order the indexes when the hit files aren't
933
already first. Reduces the cost of reordering
934
(John Arbash Meinel, #562429)
936
* Less code is loaded at startup. (Cold-cache start time is about 10-20%
938
(Martin Pool, #553017)
943
* ``bzrlib.diff.get_trees_and_branches_to_diff`` is deprecated. Use
944
``get_trees_and_branches_to_diff_locked`` instead.
947
* ``TreeTransform.commit`` supports the full set of commit parameters, and
948
auto-determines branch nick if not supplied. (Aaron Bentley)
953
* ``bzrlib.commands.Command.run_direct`` is no longer needed - the pre
954
2.1 method of calling run() to perform testing or direct use via the API
955
is now possible again. As part of this, the _operation attribute on
956
Command is now transient and only exists for the duration of ``run()``.
964
This is the first beta of the 2.2 series, leading up to a 2.2.0
965
release in July or August. Beta releases are suitable for everyday use
966
but may cause some incompatibilities with plugins. Some plugins may need
967
small updates to work with 2.2b1.
969
2.2b1 includes some changes to make merge conflicts easier to understand
970
and resolve. It also removes some old unnecessary code, and loads
971
somewhat less code at startup. It starts adding a common infrastructure
972
for dealing with colocated named branches, which can be implemented in
973
various ways in either bzr native or foreign formats. On Ubuntu and
974
other platforms with the apport bug-reporting library, there's an easier
975
path to report problems with bzr. We plan to continue with these themes
976
through the 2.2 series.
978
Over thirty bugs have been fixed, including in the log command, exporting
979
to tarballs, restarting interrupted system calls, portability of compiled
980
extensions, making backups during upgrade, and locking on FTP.
985
* BTreeGraphIndex can now take an offset to indicate that the data starts
986
somewhere other than then beginning of the file. (John Arbash Meinel)
988
* Deleted very old hidden commands ``versionedfile-list``,
989
``weave-plan-merge``, ``weave-merge-text``.
992
* ``Repository.get_inventory_sha1()`` and ``Repository.get_revision_xml()``
993
have been removed. (Jelmer Vernooij)
995
* ``Repository.get_revision_inventory()`` has been removed in favor of
996
``Repository.get_inventory()``. (Jelmer Vernooij)
998
* All test servers have been moved out of the bzrlib.transport hierarchy to
999
bzrlib.tests.test_server *except* for MemoryServer, ChrootServer and
1000
PathFilteringServer. ``bzrlib`` users may encounter test failures that can
1001
be fixed by updating the related imports from ``bzrlib.transport.xxx`` to
1002
``bzrlib.tests.test_server``.
1005
* ``BranchReferenceFormat.initialize()`` now takes an optional name argument
1006
as its second parameter, for consistency with the initialize() method of
1007
other formats. (Jelmer Vernooij)
1012
* Added ``bzr remove-branch`` command that can remove a local or remote
1013
branch. (Jelmer Vernooij, #276295)
1015
* ``bzr export`` now takes an optional argument ``--per-file-timestamps``
1016
to set file mtimes to the last timestamp of the last revision in which
1017
they were changed rather than the current time. (Jelmer Vernooij)
1019
* If the Apport crash-reporting tool is available, bzr crashes are now
1020
stored into the ``/var/crash`` apport spool directory, and the user is
1021
invited to report them to the developers from there, either
1022
automatically or by running ``apport-bug``. No information is sent
1023
without specific permission from the user. (Martin Pool, #515052)
1025
* Parsing of command lines, for example in ``diff --using``, no longer
1026
treats backslash as an escape character on Windows.
1027
(Gordon Tyler, #392428)
1029
* Plugins can be disabled by defining ``BZR_DISABLE_PLUGINS`` as
1030
a list of plugin names separated by ':' (';' on windows).
1031
(Vincent Ladeuil, #411413)
1033
* Plugins can be loaded from arbitrary locations by defining
1034
``BZR_PLUGINS_AT`` as a list of name@path separated by ':' (';' on
1035
windows). This takes precedence over ``BZR_PLUGIN_PATH`` for the
1036
specified plugins. This is targeted at plugin developers for punctual
1037
needs and *not* intended to replace ``BZR_PLUGIN_PATH``.
1038
(Vincent Ladeuil, #82693)
1040
* Tag names can now be determined automatically by ``automatic_tag_name``
1041
hooks on ``Branch`` if they are not specified on the command line.
1044
* Tree-shape conflicts can be resolved by providing ``--take-this`` and
1045
``--take-other`` to the ``bzr resolve`` command. Just marking the conflict
1046
as resolved is still accessible via the ``--done`` default action.
1049
* Merges can be proposed on Launchpad with the new lp-propose-merge command.
1050
(Aaron Bentley, Jonathan Lange)
1055
* Added docstring for ``Tree.iter_changes``
1056
(John Arbash Meinel, #304182)
1058
* Allow additional arguments to
1059
``RemoteRepository.add_inventory_by_delta()``. (Jelmer Vernooij, #532631)
1061
* Allow exporting a single file using ``bzr export``.
1062
(Michal Junák, #511987)
1064
* Allow syscalls to automatically restart when ``TextUIFactory``'s
1065
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
1066
IO, which are often poorly handled by Python's libraries and parts of
1067
bzrlib. (Andrew Bennetts, #496813)
1069
* Avoid infinite recursion when probing for apport.
1070
(Vincent Ladeuil, #516934)
1072
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1073
(Martin Pool, #331095)
1075
* Avoid truncating svn URLs.
1076
(Martin Pool, Martin von Gagern, #545185)
1078
* ``bzr add`` will not add conflict related files unless explicitly required.
1079
(Vincent Ladeuil, #322767, #414589)
1081
* ``bzr dump-btree`` now works on ``*.cix`` and ``*.six`` files. Those
1082
indices do not have reference lists, so ``dump-btree`` will simply show
1083
``None`` instead. (Andrew Bennetts, #488607)
1085
* ``bzr help`` will no longer trigger the get_missing_command hook when
1086
doing a topic lookup. This avoids prompting (like 'no command plugins/loom,
1087
did you mean log?') when getting help. In future we may trigger the hook
1088
deliberately when no help topics match from any help index.
1089
(Robert Collins, #396261)
1091
* ``bzr log -n0 -r..A.B.C`` should not crash but just consider the None
1092
revspec as representing the first revision of the branch.
1093
(Vincent Ladeuil, #519862)
1095
* ``bzr remove-tree`` can now remove multiple working trees.
1096
(Jared Hance, Andrew Bennetts, #253137)
1098
* ``bzr resolve --take-this`` and ``--take-other`` now correctly renames
1099
the kept file on content conflicts where one side deleted the file.
1100
(Vincent Ladeuil, #529968)
1102
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
1103
permissions as ``.bzr`` directory on a POSIX OS.
1104
(Parth Malwankar, #262450)
1106
* ``bzr upgrade`` now names backup directory as ``backup.bzr.~N~`` instead
1107
of ``backup.bzr``. This directory is ignored by bzr commands such as
1109
(Parth Malwankar, #335033, #300001)
1111
* Cope with non-utf8 characters inside ``.bzrignore``.
1112
(Jason Spashett, #183504)
1114
* Correctly interpret "451 Rename/move failure: Directory not empty" from
1115
FTP servers while trying to take a lock.
1116
(Martin Pool, #528722)
1118
* DirStateRevisionTree.kind() was returning wrong result when 'kind'
1119
changes occured between the workingtree and one of its parents.
1120
(Vincent Ladeuil, #535547)
1122
* Fix ``log`` to better check ancestors even if merged revisions are involved.
1123
(Vincent Ladeuil, #476293)
1125
* Loading a plugin from a given path with ``BZR_PLUGINS_AT`` doesn't depend
1126
on os.lisdir() order and is now reliable.
1127
(Vincent Ladeuil, #552922).
1129
* Many IO operations that returned ``EINTR`` were retried even if it
1130
wasn't safe to do so via careless use of ``until_no_eintr``. Bazaar now
1131
only retries operations that are safe to retry, and in some cases has
1132
switched to operations that can be retried (e.g. ``sock.send`` rather than
1134
(Andrew Bennetts, Martin <gzlist@googlemail.com>, #496813)
1136
* Path conflicts now support --take-this and --take-other even when a
1137
deletion is involved.
1138
(Vincent Ladeuil, #531967)
1140
* Network transfer amounts and rates are now displayed in SI units according
1141
to the Ubuntu Units Policy <https://wiki.ubuntu.com/UnitsPolicy>.
1142
(Gordon Tyler, #514399)
1144
* Support kind markers for socket and fifo filesystem objects. This
1145
prevents ``bzr status --short`` from crashing when those files are
1146
present. (John Arbash Meinel, #303275)
1148
* ``bzr mkdir DIR`` will not create DIR unless DIR's parent is a versioned
1149
directory. (Parth Malwankar, #138600)
1151
* SSH child processes will now ignore SIGQUIT on nix systems so breaking into
1152
the debugger won't kill the session.
1153
(Martin <gzlist@googlemail.com>, #162502)
1155
* Tolerate patches with leading noise in ``bzr-handle-patch``.
1156
(Toshio Kuratomi, Martin Pool, #502076)
1158
* ``update -r`` now supports updating to revisions that are not on
1159
mainline (i.e. it supports dotted revisions).
1160
(Parth Malwankar, #517800)
1162
* Use first apparent author not committer in GNU Changelog format.
1163
(Martin von Gagern, #513322)
1168
* ``bzrlib.merge_directive._BaseMergeDirective`` has been renamed to
1169
``bzrlib.merge_directive.BaseMergeDirective`` and is now public.
1172
* ``BranchFormat.initialize`` now takes an optional ``name`` of the colocated
1173
branch to create. (Jelmer Vernooij)
1175
* ``BzrDir.get_branch_transport`` now takes an optional ``name`` of the
1176
colocated branch to open. (Jelmer Vernooij)
1178
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
1179
can set a signal handler and call ``signal.siginterrupt(signum,
1180
False)`` for it, if the platform and Python version supports it.
1181
(Andrew Bennetts, #496813)
1183
* New ``bzrlib.initialize`` is recommended for programs using bzrlib to
1184
run when starting up; it sets up several things that previously needed
1185
to be done separately.
1186
(Martin Pool, #507710)
1188
* Exporters now support a ``per_file_timestamps`` argument to write out the
1189
timestamp of the commit in which a file revision was introduced.
1192
* New method ``BzrDir.list_branches()`` that returns a sequence of branches
1193
present in a control directory. (Jelmer Vernooij)
1195
* New method ``Repository.get_known_graph_ancestry()``.
1196
(Jelmer Vernooij, #495502)
1198
* New transport methods ``readlink``, ``symlink`` and ``hardlink``.
1201
* Remove unused ``CommandFailed`` exception.
1207
* ``bzrlib.branchbuilder.BranchBuilder.build_snapshot`` now accepts a
1208
``message_callback`` in the same way that commit does. (Robert Collins)
1210
* ``bzrlib.builtins.Commit.run`` raises ``bzrlib.errors.BoundBranchOutOfDate``
1211
rather than ``bzrlib.errors.BzrCommandError`` when the bound branch is out
1212
of date. (Gary van der Merwe)
1214
* ``bzrlib.commands.run_bzr`` is more extensible: callers can supply the
1215
functions to load or disable plugins if they wish to use a different
1216
plugin mechanism; the --help, --version and no-command name code paths
1217
now use the generic pluggable command lookup infrastructure.
1220
* ``bzrlib.errors.BoundBranchOutOfDate`` has a new field ``extra_help``
1221
which can be set to add extra help to the error. (Gary van der Merwe)
1223
* New method ``Branch.automatic_tag_name`` that can be used to find the
1224
tag name for a particular revision automatically. (Jelmer Vernooij)
1226
* The methods ``BzrDir.create_branch()``, ``BzrDir.destroy_branch()`` and
1227
``BzrDir.open_branch()`` now take an optional ``name`` argument.
1233
* bzr now has a ``.testr.conf`` file in its source tree configured
1234
appropriately for running tests with Testrepository
1235
(``https://launchpad.net/testrepository``). (Robert Collins)
1237
* Documentation about testing with ``subunit`` has been tweaked.
1240
* Known failures has been added for resolve --take-other on ParentLoop
1241
conflicts. This reflects bug #537956 without fixing it.
1244
* New ``bzrlib.tests.test_import_tariff`` can make assertions about what
1245
Python modules are loaded, to guard against startup time or library
1246
dependency regressions.
1249
* PQM will now run with subunit output. To analyze a PQM error use
1250
tribunal, or cat log | subunit-filter | subunit2pyunit. (Robert Collins)
1252
* Stop sending apport crash files to ``.cache`` in the directory from
1253
which ``bzr selftest`` was run. (Martin Pool, #422350)
1255
* Tests no longer fail if "close() called during concurrent
1256
operation on the same file object" occurs when closing the log file
1257
(which can happen if a thread tries to write to the log file at the
1258
wrong moment). An warning will be written to ``stderr`` when this
1259
happens, and another warning will be written if the log file could not
1260
be closed after retrying 100 times. (Andrew Bennetts, #531746)
