:2.2.5: NOT RELEASED YET
23
* Correctly handle ``bzr log`` and `get_known_graph_ancestry` on a
24
doubly-stacked branch.
25
(James Westby, Martin Pool, #715000)
39
* Fixed bug in the bundled copy of ConfigObj with quoting of triple quotes
40
in the value string. Fix suggested by ConfigObj's author Michael Foord.
41
(Alexander Belchenko, #710410)
52
This is a bugfix release. Only one bug has been fixed, a regression from 2.2.3
53
involving only certain operations with launchpad. Upgrading is recommended for
54
all users on earlier 2.2 releases.
59
* Fix communications with the Launchpad web service when using
60
launchpadlib >= 1.5.5. This was a latent bug in bzr's communication
61
with Launchpad's production instance, which only became a problem when
62
the default instance was switched from edge to production in bzr 2.2.3.
63
(Max Bowsher, #707075)
71
This is a bugfix release. Upgrading is recommended for all users
72
on earlier 2.2 releases.
77
* Launchpad has announced that the ``edge.launchpad.net`` instance is
78
deprecated and may be shut down in the future
79
<http://blog.launchpad.net/general/edge-is-deprecated>. Bazaar has therefore
80
been updated in this release to talk to the main (``launchpad.net``) servers,
81
rather than the ``edge`` ones. (Vincent Ladeuil, #583667)
88
This is a bugfix release. Only one bug has been fixed, a regression from 2.2.3
89
involving only certain operations with launchpad. Upgrading is recommended for
90
all users on earlier 2.2 releases.
95
* Fix communications with the Launchpad web service when using
96
launchpadlib >= 1.5.5. This was a latent bug in bzr's communication
97
with Launchpad's production instance, which only became a problem when
98
the default instance was switched from edge to production in bzr 2.2.3.
99
(Max Bowsher, #707075)
107
This is a bugfix release. Upgrading is recommended for all users
108
on earlier 2.2 releases.
113
* Launchpad has announced that the ``edge.launchpad.net`` instance is
114
deprecated and may be shut down in the future
115
<http://blog.launchpad.net/general/edge-is-deprecated>. Bazaar has therefore
116
been updated in this release to talk to the main (``launchpad.net``) servers,
117
rather than the ``edge`` ones. (Vincent Ladeuil, #583667)
122
* Avoid UnicodeDecodeError in ``bzr add`` with multiple files under a non-ascii
123
path on windows from symlink support addition. (Martin [gz], #686611)
125
* Correctly resolve content (and path) conflicts for files in subdirs.
126
(Vincent Ladeuil, #660935)
128
* Don't probe for a repository from within ``NotBranchError.__repr__``,
129
because this can cause knock-on errors at awkward times.
130
(Andrew Bennetts, #687653)
132
* Fix a crash during ``RepositoryPackCollection.pack`` caused by a
133
concurrent repository pack operation. This was particularly affecting
134
``bzr-svn`` users. (Andrew Bennetts, #701940)
136
* ``https`` access works again with recent versions of python2.7.
137
(Vincent Ladeuil, #693880)
139
* RevisionTree.is_executable no longer returns None for directories and
140
symlinks. Instead, it returns False, like other Trees and methods.
141
(Aaron Bentley, #681885)
149
This is a bugfix release. None of these bugfixes are critical, but upgrading
150
is recommended for all users on earlier 2.2 releases.
155
* ``bzr resolve --take-other <file>`` will not crash anymore if ``<file>``
156
is involved in a text conflict (but the conflict is still not
157
resolved). (Vincent Ladeuil, #646961)
159
* Commit in a bound branch or heavyweight checkout now propagates tags
160
(e.g. from a merge) to the master branch (and informs the user if there
161
is a conflict). (Andrew Bennetts, #603395)
163
* Correctly set the Content-Type header when HTTP POSTing to comply
164
with stricter web frameworks. (Vincent Ladeuil, #665100)
166
* ``NotBranchError`` no longer allows errors from calling
167
``bzrdir.open_repository()`` to propagate. This is unhelpful at best,
168
and at worst can trigger infinite loops in callers. (Andrew Bennetts)
170
* Skip tests that needs a bzr source tree when there isn't one. This is
171
needed to succesfully run the test suite for installed versions.
172
(Vincent Ladeuil, #644855).
174
* Skip the tests that requires respecting the chmod bits when running as
175
root. Including the one that wasn't present in 2.1.
176
(Vincent Ladeuil, #646133)
178
* Using bzr with `lp:` URLs behind an HTTP proxy should work.
179
(Robert Collins, #558343)
181
* Windows installers no longer requires the Microsoft vcredist to be
183
(Martin [gz], Gary van der Merwe, #632465)
185
* Close leaked socket to SSH subprocesses, which caused dput sftp uploads
186
to hang. (Max Bowsher, #659590)
191
* Add ``tests/ssl_certs/ca.crt`` to the required test files list. Test
192
involving the pycurl https test server fail otherwise when running
193
selftest from an installed version. (Vincent Ladeuil, #651706)
195
* Fix tests that failed when run under ``LANG=C``.
196
(Andrew Bennetts, #632387)
204
This is a bugfix release which also includes bugfixes from 2.0.6 and
205
2.1.3. None are critical, but upgrading is recommended for all users on
206
earlier 2.2 releases.
211
* Additional merges after an unrelated branch has been merged with its
212
history no longer crash when deleted files are involved.
213
(Vincent Ladeuil, John Arbash Meinel, #375898)
215
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
216
previously-unversioned directory within the tree: the directory is
217
marked versioned too.
218
(Martin Pool, #192859)
220
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
221
target of the symlink.
222
(Martin Pool, John Arbash Meinel, #128562)
224
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
225
permissions as ``.bzr`` directory on a POSIX OS.
226
(Parth Malwankar, #262450)
228
* CommitBuilder now uses the committer instead of _config.username to generate
229
the revision-id. (Aaron Bentley, #614404)
231
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
232
way which should help avoid problems with concurrent writers.
233
(Vincent Ladeuil, #525571)
235
* Cope with Microsoft FTP server that returns reply '250 Directory
236
created' when mkdir succeeds. (Martin Pool, #224373)
238
* Don't traceback trying to unversion children files of an already
239
unversioned directory. (Vincent Ladeuil, #494221)
241
* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
242
contains only NUL bytes). Instead warn the user, and allow ``bzr
243
break-lock`` to remove it. (Andrew Bennetts, #619872)
245
* Fix ``AttributeError on parent.children`` when adding a file under a
246
directory that was a symlink in the previous commit.
247
(Martin Pool, #192859)
249
* Fix ``AttributeError: 'NoneType' object has no attribute 'close'`` in
250
``_close_ssh_proc`` when using ``bzr+ssh://``. This was causing
251
connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on
252
stderr in some other circumstances. (Andrew Bennetts, #633745)
254
* Only call ``setlocale`` in the bzr startup script on posix systems. This
255
avoids an issue with the newer windows C runtimes used by Python 2.6 and
256
later which can mangle bytestrings printed to the console.
257
(Martin [gz], #631350)
259
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
260
which can result in "missing referenced chk root keys" errors when
261
fetching from repositories with affected revisions.
262
(Andrew Bennetts, #522637)
264
* Raise ValueError instead of a string exception.
265
(John Arbash Meinel, #586926)
267
* Reduce peak memory by one copy of compressed text.
268
(John Arbash Meinel, #566940)
270
* Repositories accessed via a smart server now reject being stacked on a
271
repository in an incompatible format, as is the case when accessing them
272
via other methods. This was causing fetches from those repositories via
273
a smart server (e.g. using ``bzr branch``) to receive invalid data.
274
(Andrew Bennetts, #562380)
276
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
277
error. This error was caused by 2.0 not being updated when upstream
278
python merged the end of run patch, which chose ``stopTestRun`` rather than
279
``done``. (Robert Collins, #571437)
281
* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``
282
being thrown from ``xml_serializer`` on certain cElementTree setups.
283
(Martin [gz], #254278)
285
* Upgrading or fetching from a non-rich-root repository to a rich-root
286
repository (e.g. from pack-0.92 to 2a) no longer fails with
287
``'Inter1and2Helper' object has no attribute 'source_repo'``. This was
288
a regression from Bazaar 2.1. (Andrew Bennetts, #636930)
290
* When passing a file to ``UTF8DirReader`` make sure to close the current
291
directory file handle after the chdir fails. Otherwise when passing many
292
filenames into a command line ``bzr status`` we would leak descriptors.
293
(John Arbash Meinel, #583486)
298
* Fix a lot of references in the docs to the old http://bazaar-vcs.org to
299
the new http://bazaar.canonical.com or http://wiki.bazaar.canonical.com
300
(John Arbash Meinel, #617503)
305
* Remove used and broken code path in ``BranchInitHookParams.__repr__``.
311
* ``build_tree_contents`` can create symlinks.
312
(Martin Pool, John Arbash Meinel)
314
* Tracebacks from a parameterized test are no longer reported against every
315
parameterization of that test. This was done by adding a hack to
316
``bzrlib.tests.clone_test`` so that it no longer causes
317
testtools.TestCase instances to share a details dict.
318
(Andrew Bennetts, #625574)
326
This release marks the start of another long-term-stable series. From
327
here, we will only make bugfix releases on the 2.2 series (2.2.1, etc),
328
while 2.3 will become our new development series. The 2.0 and 2.1 series
329
will also continue to get bugfixes. (Currently 2.0 is planned to be
330
supported for another 6 months.)
332
This is primarily a bugfix and polish release over the 2.1 series, with
333
a large number of bugs fixed (>120), and some performance improvements.
335
There are some compatibility changes in this release. For users of bzrlib
336
as a library, we now request that they call ``bzrlib.initialize`` and use
337
the returned context manager appropriately. For commandline users we no
338
longer guess user identity for ``bzr commit``, users must specify their
339
identity using ``bzr whoami`` (you don't need to specify your identity for
340
readonly operations).
342
Users are encouraged to upgrade from the other stable series.
347
* BzrError subclasses no longer support the name "message" to be used
348
as an argument for __init__ or in _fmt format specification as this
349
breaks in some Python versions. errors.LockError.__init__ argument
350
is now named "msg" instead of earlier "message".
351
(Parth Malwankar, #603461)
353
* The old ``bzr selftest --benchmark`` option has been removed.
354
<https://launchpad.net/bzr-usertest> is an actively-maintained
355
macrobenchmark suite.
361
* ``bzr ignore PATTERNS`` exits with error if a bad pattern is supplied.
362
``InvalidPattern`` exception error message now shows faulting
364
(Parth Malwankar #300062)
366
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
367
way which should help avoid problems with concurrent writers.
368
(Vincent Ladeuil, #525571)
370
* Don't traceback trying to unversion children files of an already
371
unversioned directory. (Vincent Ladeuil, #494221)
373
* ``HTTP/1.1`` test servers now set a ``Content-Length`` header to comply
374
with pedantic ``HTTP/1.1`` clients. (Vincent Ladeuil, #568421)
376
* Progress bars prefer to truncate the text message rather than the
377
counters. The spinner is shown between the network transfer indicator
378
and the progress message. Progress bars are correctly cleared off when
379
they finish. (Martin Pool, #611127)
381
* Recursive binding for checkouts is now detected by bzr. A clear error
382
message is shown to the user. (Parth Malwankar, #405192)
387
* Add ``bzrlib.merge.MergeIntoMerger``, which can merge part or all of a
388
tree, and works with unrelated branches. (Andrew Bennetts)
390
* Add py2exe windows target ``bzrw.exe``. This allow for starting a Bazaar
391
GUI with out have a console open in the background.
392
(Gary van der Merwe, #433781)
397
* ``bzr help patterns`` now explains case insensitive patterns and
398
points to Python regular expression documentation.
399
(Parth Malwankar, #594386)
404
* Delete ``ProgressTask.note``, which was deprecated in 2.1.
409
* Unit test added to ensure that "message" is not uses as a format variable
410
name in BzrError subclasses as this conflicts with some Python versions.
411
(Parth Malwankar, #603461)
416
:Codename: Monkey Magic
420
This fourth and final beta in the 2.2 series now stabilizes the internal
421
APIs. Plugin authors are recommended to ensure their releases are
422
compatible, so that 2.2rc1 can be a true release candidate, containing
423
stable and compatible plugin versions.
425
For users of bzrlib as a library, one of the primary changes is to request
426
that they call ``bzrlib.initialize`` and use the returned context manager
429
Better interaction with ``bzr-loom`` to make sure branching from a loom
430
even over a smart server still yields a local loom. Not to mention lots of
436
* bzrlib library users now need to call ``__enter__`` and ``__exit__`` on
437
the result of ``bzrlib.initialize``. This change was made when fixing
438
the bad habit recent bzr versions have had of leaving progress bars
439
behind on the screen. That required calling another function before
440
exiting the program, and it made sense to provide a full context
441
manager at the same time. (Robert Collins)
443
* The ``bzr`` front end now requires a ``bzrlib.ui.ui_factory`` which is a
444
context manager in the Python 2.5 and above sense. The bzrlib base class
445
is such a manager, but third party UI factories which do not derive from
446
``bzrlib.ui.UIFactory`` will be incompatible with the command line front
449
* URLs like ``foo:bar/baz`` are now always parsed as a URL with scheme "foo"
450
and path "bar/baz", even if bzr does not recognize "foo" as a known URL
451
scheme. Previously these URLs would be treated as local paths.
458
* Support ``--directory`` option for a number of additional commands:
459
conflicts, merge-directive, missing, resolve, shelve, switch,
460
unshelve, whoami. (Martin von Gagern, #527878)
465
* ``bzr branch`` to a new repository with a default stacking policy no
466
longer transfers the full history unnecessarily.
467
(Andrew Bennetts, #597942)
469
* ``bzr init`` does not recursively scan directory contents anymore
470
leading to faster init for directories with existing content.
471
(Martin [gz], Parth Malwankar, #501307)
473
* ``bzr log --exclude-common-ancestry`` is now taken into account for
474
linear ancetries. (Vincent Ladeuil, #575631)
476
* ``bzr log -r branch:REMOTE`` can now properly log the remote branch,
477
rather than trying to fetch the data locally and failing because of a
478
readonly error. (Martin von Gagern, #149270)
480
* ``bzr pull`` now works when a lp: URL is explicitly defined as the parent
481
or pull location in locations.conf or branch.conf.
482
(Gordon Tyler, #534787)
484
* ``bzr reconfigure --unstacked`` now works with branches accessed via a
485
smart server. (Andrew Bennetts, #551525)
487
* ``BzrDir.find_branches`` should ignore branches with missing repositories.
488
(Marius Kruger, Robert Collins)
490
* ``BzrDir.find_bzrdirs`` should ignore dirs that raises PermissionDenied.
491
(Marius Kruger, Robert Collins)
493
* Ensure that wrong path specifications in ``BZR_PLUGINS_AT`` display
494
proper error messages. (Vincent Ladeuil, #591215)
496
* Explicitly removing ``--profile-imports`` option from parsed command-line
497
arguments on Windows, because bzr script does the same.
498
(Alexander Belchenko, #588277)
500
* Fetching was slightly confused about the best code to use and was
501
using a new code path for all branches, resulting in more lookups than
502
necessary on old branches. (Robert Collins, #593515)
504
* Final fix for 'no help for command' issue. We now show a clean message
505
when a command has no help, document how to set help more clearly, and
506
test that all commands available to the test suite have help.
507
(Robert Collins, #177500)
509
* Invalid patterns supplied to ``Globster`` or ``lazy_regex`` now raise
510
``InvalidPattern`` exception showing clear error message to the user.
511
(Parth Malwankar #300062)
513
* Progress output is cleaned up when exiting. (Aaron Bentley)
515
* Raise ValueError instead of a string exception.
516
(John Arbash Meinel, #586926)
518
* Relative imports in plugins are now handled correctly when using
519
BZR_PLUGINS_AT. (Vincent Ladeuil, #588959)
521
* ``ScriptRunner`` now strips off leading indentation from test scripts,
522
which previously caused "SyntaxError: No command for line".
525
* Show unicode filenames in diff headers using terminal encoding.
526
(Alexander Belchenko, Bug #382699)
527
NOTE for Windows users: If user need to save diff to file then user need to
528
change encoding of the terminal to ANSI encoding with command ``chcp XXX``
529
(e.g. ``chcp 1251`` for Russian Windows).
531
* URL displayed for use with ``break-lock`` when smart server sees lock
532
contention are now valid. Default timeout for lock contention retry is
533
now 30 seconds instead of 300 seconds.
534
(Parth Malwankar, #250451)
536
* ``walkdirs`` now raises a useful message when the filenames are not using
537
the filesystem encoding. (Eric Moritz, #488519)
539
* Enable debugging of bzr on windows with pdb and other tools. This was
540
broken because we call GetCommandLineW on windows. The fix adjusts the
541
command line we get to be the same length as sys.argv.
542
(Jason Spashett, Alexander Belchenko, #587868)
547
* Bazaar now reads data from SSH connections more efficiently on platforms
548
that provide the ``socketpair`` function, and when using paramiko.
549
(Andrew Bennetts, #590637)
551
* ``Branch.copy_content_into`` is now a convenience method dispatching to
552
a ``InterBranch`` multi-method. This permits ``bzr-loom`` and other
553
plugins to intercept this even when a ``RemoteBranch`` proxy is in use.
554
(Robert Collins, #201613)
556
* ``Branch`` formats can now be loaded lazily by registering a
557
``MetaDirBranchFormatFactory`` rather than an actual format. This will
558
cause the named format class to be loaded only when an enumeration of
559
formats is needed or when the format string for the object is
560
encountered. (Robert Collins, Jelmer Vernooij)
562
* The encoding that bzr uses to output things other than file content can
563
now be overridden via the output_encoding configuration option.
564
(Martin Pool, #340394)
566
* Use lazy imports in ``bzrlib/merge.py`` so that plugins like ``news_merge``
567
do not cause modules to be loaded unnecessarily just because the plugin
568
registers a merge hook. This improves ``bzr rocks`` time by about 25%
569
in a default installation (with just the core plugins).
575
* Added ``regression`` tag to our tags list. (Robert Collins)
577
* Improved our release checklist to have a bit less churn and leave things
578
ready-to-go for the next action (including other people doing
579
development). (Robert Collins)
581
* Remove obsolete discussion of PQM in documentation about how to
582
contribute to Bazaar. (Martin Pool, #588444)
587
* ``bzrlib.branch.InterBranch._get_branch_formats_to_test`` now returns
588
an iterable of format pairs, rather than just a single pair, permitting
589
InterBranch objects that work with multiple permutations to be
590
comprehensively tested. (Robert Collins)
592
* ``bzrlib.lsprof.profile`` will no longer silently generate bad threaded
593
profiles when concurrent profile requests are made. Instead the profile
594
requests will be serialised. Reentrant requests will now deadlock.
597
* ``bzrlib.knit.KnitSequenceMatcher``, which has been deprecated since
598
2007, has been deleted. Use ``PatienceSequenceMatcher`` from
599
``bzrlib.patiencediff`` instead. (Andrew Bennetts)
601
* ``bzrlib.re_compile_checked`` is now deprecated. Caller should handle
602
``bzrlib.errors.InvalidPattern`` exception thrown by ``re.match`` in
603
case the default error message not suitable for the use case.
606
* ``bzrlib.tests.blackbox.ExternalBase`` is deprecated. It provided only
607
one method ``check_output``, and we now recommend checking command
608
output using ``run_script``. (Martin Pool)
610
* ``bzrlib.transport.ssh.SSHVendor.connect_ssh`` now returns an object
611
that implements the interface of ``bzrlib.transport.ssh.SSHConnection``.
612
Third-party implementations of ``SSHVendor`` may need to be updated
613
accordingly. Similarly, any code using ``SSHConnection`` directly will
614
need to be updated. (Andrew Bennetts)
616
* The constructor of ``bzrilb.smart.medium.SmartSSHClientMedium`` has
617
changed to take an ``SSHParams`` instance (replacing many individual
618
values). (Andrew Bennetts)
623
* ``bzrlib.osutils.get_terminal_encoding`` will now only mutter its
624
selection when explicitly requested; this avoids many duplicate calls
625
being logged when helpers, wrappers and older code that manually calls
626
it are executed it is now logged deliberately by the ui setup code.
629
* Improved ``bzrlib.urlutils`` to handle lp:foo/bar URLs. (Gordon Tyler)
631
* ``bzrlib._c_static_tuple.StaticTuple`` now implements ``__sizeof__``, so
632
that ``sys.getsizeof`` and other memory analysis tools will report more
633
accurate results. (Andrew Bennetts)
635
* The symbol_versioning module can now cleanup after itself -
636
``suppress_deprecation_warnings`` now returns a cleanup function.
642
* Add ``bzrlib.tests.fixtures`` to hold code for setting up objects
643
to test. (Martin Pool)
645
* ``test_import_tariff`` now respects BZR_PLUGINS_AT and BZR_PLUGINS_DISABLE.
646
(Vincent Ladeuil, #595587)
654
This third beta in the 2.2 series brings with it all the goodness of 2.1.2
655
and 2.0.6 (though it preceeds 2.0.6 slightly). Of particular note for
656
users are compatibility fixes with bzr 1.5 and below servers, a hopeful
657
end to the EINTR errors caused by SIGWINCH interactions, a shiny new
658
bash completion script and bzr will no longer guess at identity details -
659
it was too unreliable in reality. Use ``bzr whoami`` on every new install.
660
For developers we have some API changes which may impact plugins as well
661
as a bunch of our regular improvements to internal clarity and test
667
* An API break has been made to the lock_write method of ``Branch`` and
668
``Repository`` objects; they now return ``branch.BranchWriteLockResult``
669
and ``repository.RepositoryWriteLockResult`` objects. This makes
670
changing the API in future easier and permits some cleaner calling code.
671
The lock_read method has also changed from having no defined return
672
value to returning ``LogicalLockResult`` objects.
675
* ``bzr`` does not try to guess the username as ``username@hostname``
676
and requires it to be explictly set. This can be set using ``bzr
677
whoami``. (Parth Malwankar, #549310)
679
* ``bzrlib.commands.Command`` will now raise ValueError during
680
construction if there is no __doc__ set. (Note, this will be reverted in
681
2.2b4) (Robert Collins)
683
* The source tree no longer contains a contrib/zsh/_bzr completion
684
script. The new file contrib/zsh/README suggests alternatives.
685
(Martin von Gagern, #560030)
690
* ``bzr commit`` accepts ``-p`` (for "patch") as a shorter name for
692
(Parth Malwankar, #571467)
694
* ``bzr ignore`` now supports a ``--default-rules`` option that displays
695
the default ignore rules used by bzr. The flag ``--old-default-rules``
696
is no longer supported by ``ignore``.
697
(Parth Malwankar, #538703)
699
* ``bzr pack`` now supports a ``--clean-obsolete-packs`` option that
700
can save disk space by deleting obsolete pack files created during the
702
(Parth Malwankar, #304320)
704
* New command line option ``--authors`` to ``bzr log`` allows users to
705
select which of the apparent authors and committer should be
706
included in the log. Defaults depend on format. (Martin von Gagern, #513322)
708
* Support ``--directory`` option for a number of additional commands:
709
added, annotate, bind, cat, cat-revision, clean-tree, deleted,
710
export, ignore, ignored, lookup-revision, ls, modified, nick,
711
re-sign, unbind, unknowns.
712
(Martin von Gagern, #527878)
714
* The bash_completion plugin from the bzr-bash-completion project has
715
been merged into the tree. It provides a bash-completion command and
716
replaces the outdated ``contrib/bash/bzr`` script with a version
717
using the plugin. (Martin von Gagern, #560030)
719
* A new transport based on GIO (the Gnome I/O library) provides access to
720
Samba shares, WebDAV using gio+smb and gio+dav. It is also possible to
721
use gio for some already existing transport methods as gio+file,
728
* Alias information shown by ``bzr help`` is now accurate. This
729
was showing an internal object name for some plugin aliases.
730
(Parth Malwankar, #584650)
732
* ``.bazaar``, ``.bazaar/bazaar.conf`` and ``.bzr.log`` inherit user and
733
group ownership from the containing directory. This allow bzr to work
735
(Martin <gzlist@googlemail.com>, Parth Malwankar, #376388)
737
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
738
support of bzr-externals and scmproj plugins.
739
(Alexander Belchenko, bug #572098)
741
* ``bzr ignore`` will no longer add duplicate patterns to .bzrignore.
742
(Gordon Tyler, #572092)
744
* ``bzr log --exclude-common-ancestry -r X..Y`` displays the revisions that
745
are part of Y ancestry but not part of X ancestry (aka the graph
747
(Vincent Ladeuil, #320119)
749
* ``bzr lp-propose`` which was switched to use production Launchpad API
750
servers a few commits ago has been reverted to use edge: there is a
751
problem with using production which isn't trivially obvious, so we've
752
filed a bug to track it, and until thats fixed will be using edge.
753
(Robert Collins, #583667)
755
* ``bzr rm`` should not refuse to delete directories which contained a file
756
which has been moved elsewhere in the tree after the previous commit.
757
(Marius Kruger, Daniel Watkins, #129880)
759
* ``bzr selftest --parallel=fork`` wait for its children avoiding zombies.
760
(Vincent Ladeuil, #566670)
762
* ``bzr selftest`` should not use ui.note() since it's not unicode safe.
763
(Vincent Ladeuil, #563997)
765
* CommitBuilder refuses to create revisions whose trees have no root.
768
* Do not register a SIGWINCH signal handler, instead just poll for the
769
terminal width as needed. This avoids the "Interrupted System Call"
770
problems that occur on POSIX with all currently released versions of
772
(Andrew Bennetts, #583941)
774
* Don't mention --no-strict when we just issue the warning about unclean trees.
775
(Vincent Ladeuil, #401599)
777
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
779
(Andrew Bennetts, #528041)
781
* Improved progress bar for fetch (2a format only). Bazaar now shows an
782
estimate of the number of records to be fetched vs actually fetched.
783
(Parth Malwankar, #374740, #538868)
785
* Reduce peak memory by one copy of compressed text.
786
(John Arbash Meinel, #566940)
788
* ``RemoteBranch.lock_write`` raises ``ReadOnlyError`` if called during a
789
read lock, rather than causing an ``AttributeError``.
790
(Andrew Bennetts, Danilo Segan, #582781)
792
* Selftest was failing with testtools 0.9.3, which caused an
793
AssertionError raised from a cleanUp to be reported as a Failure, not an
794
Error, breaking on of our test hygiene tests.
795
(Robert Collins, Vincent Ladeuil).
797
* ``set_user_option`` with a dict on remote branches no longer fails with
798
an AttributeError. There is a new ``Branch.set_config_option_dict`` RPC
799
to support this efficiently.
800
(Andrew Bennetts, #430382)
802
* Show the filenames when a file rename fails so that the error will be
804
(Martin Pool, #491763)
806
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
807
(John Arbash Meinel, #582656)
809
* Unicode characters in aliases are now handled correctly and do not cause
810
UnicodeEncodeError exception. (Parth Malwankar, #529930)
812
* Unicode commit messages that are the same as a file name no longer cause
813
UnicodeEncodeError. ``ui.text.show_warning`` now handles unicode
815
(Parth Malwankar, #563646)
817
* When passing a file to ``UTF8DirReader`` make sure to close the current
818
directory file handle after the chdir fails. Otherwise when passing many
819
filenames into a command line ``bzr status`` we would leak descriptors.
820
(John Arbash Meinel, #583486)
825
* ``append_revisions_only`` will now be interpreted as a boolean and a
826
warning emitted if illegal values are used. Note that for projects
827
that needs to maintain compatibility with previsous bzr versions,
828
only 'True' and 'False' strings must be used (previous versions of
829
bzr will interpret all strings differing from 'True'
830
(case-sensitive) as false.
831
(Brian de Alwis, Vincent Ladeuil)
833
* ``bzr ls`` now supports short options for existing long options.
834
``-k/--kind``, ``-i/--ignored``, ``-u/--unknown`` and ``-0/--null``.
835
(Parth Malwankar, #181124)
837
* ``Config.get_user_option_as_bool`` will now warn if a value cannot
838
be interpreted as a boolean.
841
* The all-in-one Windows installer will now be built with docstrings stripped
842
from the library zip, reducing the size and slightly improving cold startup
843
time. Bundled plugins are unchanged for the moment, but if adding other new
844
plugins to an all-in-one installation, ensure they are compiled and
845
installed with -O1 or help may not work. (Martin [gz])
850
* Added ``bzrlib.merge.PerFileMerger``, a more convenient way to write
851
some kinds of ``merge_file_content`` hook functions.
854
* `BzrDir`, `Branch`, `Repository` and `WorkingTree` now all support `user_url`,
855
`user_transport`, `control_url` and `control_transport` members pointing
856
respectively to the directory containing the ``.bzr`` control directory,
857
and to the directory within ``.bzr`` used for the particular component.
858
All of them inherit from `ControlComponent` which provides default
862
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
863
expected to return an object which can be used to unlock them. This reduces
864
duplicate code when using cleanups. The previous 'tokens's returned by
865
``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
866
on the result of the lock_write. ``repository.RepositoryWriteLockResult``
867
and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
869
* ``Repository.refresh_data`` may now be called in a write group on
870
pack-based repositories. Older repositories will still raise an error
871
in this case. Subclasses of ``Repository`` can still override
872
``Repository._refresh_data``, but are now responsible for raising
873
``bzrlib.repository.IsInWriteGroupError`` if they do not support
874
``refresh_data`` during a write group.
875
(Andrew Bennetts, #574236)
880
* ``chk_map._bytes_to_text_key`` is now an optimized function to extract
881
the (file-id, revision-id) key from a CHKInventory entry. This can
882
potentially shave 5-10% time off during a large fetch. Related to bug
883
#562666. (John Arbash Meinel)
885
* ``log._get_info_for_log_files`` now takes an add_cleanup callable.
888
* ``_remember_remote_is_before`` no longer raises AssertionError when
889
suboptimal network behaviour is noticed; instead it just mutters to the
890
log file (and warns the user if they have set the ``hpss`` debug flag).
891
This was causing unnecessary aborts for performance bugs that are minor
893
(Andrew Bennetts, #528041)
895
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
896
files loaded from disk. To ensure docstrings needed for help are never
897
stripped, the prefix ``__doc__ =`` should now be used.
898
(Martin <gzlist@googlemail.com>)
900
* No longer require zlib headers to build extensions, and remove the need
901
for seperate copy of zlib library on windows.
902
(John Arbash Meinel, Martin <gzlist@googlemail.com>, #566923)
907
* Added ``bzrlib.tests.matchers`` as a place to put matchers, along with
908
our first in-tree matcher. See the module docstring for details.
911
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
912
(Gordon Tyler, #551332)
914
* Workaround ``Crypto.Random`` check leading to spurious test
915
failures on Lucid, FreeBSD and gentoo.
916
(Vincent Ladeuil, #528436)
918
* New class ``ExecutableFeature`` for checking the availability of
919
executables on the ``PATH``. Migrated from bash_completion plugin.
928
This is a somewhat early second beta of the 2.2 series, to fix a python2.4
929
incompatibility in the 2.2b1 release. It also includes a swag of
930
performance, usability and correctness improvements: test feedback on all
931
of these would be welcome.
937
* ``bzr diff`` now supports a --format option, which can be used to
938
select alternative diff formats. (Jelmer Vernooij, #555994)
943
* ``bzr dpush``, ``bzr push`` and ``bzr send`` will now issue a warning
944
instead of failing when dirty trees are involved. The corresponding
945
``dpush_strict``, ``push_strict`` and ``send_strict`` should be set to
946
True explicitly to get the previous behaviour.
947
(Vincent Ladeuil, #519319)
949
* ``bzr export`` to tar file does not fail if any parent directory
950
contains unicode characters. This works around upstream Python bug
951
http://bugs.python.org/issue8396 .
952
(Parth Malwankar, #413406)
954
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
955
(Aaron Bentley, #559436)
957
* ``bzr update`` when a pending merge in the working tree has been merged
958
into the master branch will no longer claim that old commits have become
959
pending merges. (Robert Collins, #562079)
961
* ``bzrlib.mutabletree.MutableTree.commit`` will now support a passed in
962
config as in previous versions of bzrlib. (Robert Collins)
964
* Fix glitch in the warning about unclean trees display.
965
(Vincent Ladeuil, #562665)
967
* Fixed Python2.4 incompatibilities in the bzr2.2b1 source tarball.
970
* Help messages generated by ``RegistryOption.from_kwargs`` list the
971
switches in alphabetical order, rather than in an undefined order.
972
(Martin von Gagern, #559409)
974
* Make sure the ``ExecutablePath`` and ``InterpreterPath`` are set in
975
Apport crash reports, to avoid "This problem report applies to a program
976
which is not installed any more" error.
977
(Martin Pool, James Westby, #528114)
979
* Reset ``siginterrupt`` flag to False every time we handle a signal
980
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
981
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
982
errors compared to registering ``signal.signal`` directly.
985
* When invoked with a range revision, ``bzr log`` doesn't show revisions
986
that are not part of the Y revisions ancestry anymore when invoked with
988
(Vincent Ladeuil, #474807)
990
* Properly handle ``param_name`` attribute for ``ListOption``.
991
(Martin von Gagern, #387117)
996
* ``bzr commit`` will prompt before using a commit message that was
997
generated by a template and not edited by the user.
998
(Robert Collins, #530265)
1000
* ``bzr diff`` read-locks the trees and branches only once, saving about
1001
10-20ms on ``bzr diff`` in a bzr.dev tree.
1004
* ``bzr missing`` read-locks the branches only once.
1007
* ``bzr pull`` locks the branches and tree only once.
1010
* Index lookups in pack repositories search recently hit pack files first.
1011
In repositories with many pack files this can greatly reduce the
1012
number of files accessed, the number of bytes read, and the number of
1013
read calls. An incremental pull via plain HTTP takes half the time and
1014
bytes for a moderately large repository. (Andrew Bennetts)
1016
* Index lookups only re-order the indexes when the hit files aren't
1017
already first. Reduces the cost of reordering
1018
(John Arbash Meinel, #562429)
1020
* Less code is loaded at startup. (Cold-cache start time is about 10-20%
1022
(Martin Pool, #553017)
1027
* ``bzrlib.diff.get_trees_and_branches_to_diff`` is deprecated. Use
1028
``get_trees_and_branches_to_diff_locked`` instead.
1031
* ``TreeTransform.commit`` supports the full set of commit parameters, and
1032
auto-determines branch nick if not supplied. (Aaron Bentley)
1037
* ``bzrlib.commands.Command.run_direct`` is no longer needed - the pre
1038
2.1 method of calling run() to perform testing or direct use via the API
1039
is now possible again. As part of this, the _operation attribute on
1040
Command is now transient and only exists for the duration of ``run()``.
1048
This is the first beta of the 2.2 series, leading up to a 2.2.0
1049
release in July or August. Beta releases are suitable for everyday use
1050
but may cause some incompatibilities with plugins. Some plugins may need
1051
small updates to work with 2.2b1.
1053
2.2b1 includes some changes to make merge conflicts easier to understand
1054
and resolve. It also removes some old unnecessary code, and loads
1055
somewhat less code at startup. It starts adding a common infrastructure
1056
for dealing with colocated named branches, which can be implemented in
1057
various ways in either bzr native or foreign formats. On Ubuntu and
1058
other platforms with the apport bug-reporting library, there's an easier
1059
path to report problems with bzr. We plan to continue with these themes
1060
through the 2.2 series.
1062
Over thirty bugs have been fixed, including in the log command, exporting
1063
to tarballs, restarting interrupted system calls, portability of compiled
1064
extensions, making backups during upgrade, and locking on FTP.
1066
Compatibility Breaks
1067
********************
1069
* BTreeGraphIndex can now take an offset to indicate that the data starts
1070
somewhere other than then beginning of the file. (John Arbash Meinel)
1072
* Deleted very old hidden commands ``versionedfile-list``,
1073
``weave-plan-merge``, ``weave-merge-text``.
1076
* ``Repository.get_inventory_sha1()`` and ``Repository.get_revision_xml()``
1077
have been removed. (Jelmer Vernooij)
1079
* ``Repository.get_revision_inventory()`` has been removed in favor of
1080
``Repository.get_inventory()``. (Jelmer Vernooij)
1082
* All test servers have been moved out of the bzrlib.transport hierarchy to
1083
bzrlib.tests.test_server *except* for MemoryServer, ChrootServer and
1084
PathFilteringServer. ``bzrlib`` users may encounter test failures that can
1085
be fixed by updating the related imports from ``bzrlib.transport.xxx`` to
1086
``bzrlib.tests.test_server``.
1089
* ``BranchReferenceFormat.initialize()`` now takes an optional name argument
1090
as its second parameter, for consistency with the initialize() method of
1091
other formats. (Jelmer Vernooij)
1096
* Added ``bzr remove-branch`` command that can remove a local or remote
1097
branch. (Jelmer Vernooij, #276295)
1099
* ``bzr export`` now takes an optional argument ``--per-file-timestamps``
1100
to set file mtimes to the last timestamp of the last revision in which
1101
they were changed rather than the current time. (Jelmer Vernooij)
1103
* If the Apport crash-reporting tool is available, bzr crashes are now
1104
stored into the ``/var/crash`` apport spool directory, and the user is
1105
invited to report them to the developers from there, either
1106
automatically or by running ``apport-bug``. No information is sent
1107
without specific permission from the user. (Martin Pool, #515052)
1109
* Parsing of command lines, for example in ``diff --using``, no longer
1110
treats backslash as an escape character on Windows.
1111
(Gordon Tyler, #392428)
1113
* Plugins can be disabled by defining ``BZR_DISABLE_PLUGINS`` as
1114
a list of plugin names separated by ':' (';' on windows).
1115
(Vincent Ladeuil, #411413)
1117
* Plugins can be loaded from arbitrary locations by defining
1118
``BZR_PLUGINS_AT`` as a list of name@path separated by ':' (';' on
1119
windows). This takes precedence over ``BZR_PLUGIN_PATH`` for the
1120
specified plugins. This is targeted at plugin developers for punctual
1121
needs and *not* intended to replace ``BZR_PLUGIN_PATH``.
1122
(Vincent Ladeuil, #82693)
1124
* Tag names can now be determined automatically by ``automatic_tag_name``
1125
hooks on ``Branch`` if they are not specified on the command line.
1128
* Tree-shape conflicts can be resolved by providing ``--take-this`` and
1129
``--take-other`` to the ``bzr resolve`` command. Just marking the conflict
1130
as resolved is still accessible via the ``--done`` default action.
1133
* Merges can be proposed on Launchpad with the new lp-propose-merge command.
1134
(Aaron Bentley, Jonathan Lange)
1139
* Added docstring for ``Tree.iter_changes``
1140
(John Arbash Meinel, #304182)
1142
* Allow additional arguments to
1143
``RemoteRepository.add_inventory_by_delta()``. (Jelmer Vernooij, #532631)
1145
* Allow exporting a single file using ``bzr export``.
1146
(Michal Junák, #511987)
1148
* Allow syscalls to automatically restart when ``TextUIFactory``'s
1149
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
1150
IO, which are often poorly handled by Python's libraries and parts of
1151
bzrlib. (Andrew Bennetts, #496813)
1153
* Avoid infinite recursion when probing for apport.
1154
(Vincent Ladeuil, #516934)
1156
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1157
(Martin Pool, #331095)
1159
* Avoid truncating svn URLs.
1160
(Martin Pool, Martin von Gagern, #545185)
1162
* ``bzr add`` will not add conflict related files unless explicitly required.
1163
(Vincent Ladeuil, #322767, #414589)
1165
* ``bzr dump-btree`` now works on ``*.cix`` and ``*.six`` files. Those
1166
indices do not have reference lists, so ``dump-btree`` will simply show
1167
``None`` instead. (Andrew Bennetts, #488607)
1169
* ``bzr help`` will no longer trigger the get_missing_command hook when
1170
doing a topic lookup. This avoids prompting (like 'no command plugins/loom,
1171
did you mean log?') when getting help. In future we may trigger the hook
1172
deliberately when no help topics match from any help index.
1173
(Robert Collins, #396261)
1175
* ``bzr log -n0 -r..A.B.C`` should not crash but just consider the None
1176
revspec as representing the first revision of the branch.
1177
(Vincent Ladeuil, #519862)
1179
* ``bzr remove-tree`` can now remove multiple working trees.
1180
(Jared Hance, Andrew Bennetts, #253137)
1182
* ``bzr resolve --take-this`` and ``--take-other`` now correctly renames
1183
the kept file on content conflicts where one side deleted the file.
1184
(Vincent Ladeuil, #529968)
1186
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
1187
permissions as ``.bzr`` directory on a POSIX OS.
1188
(Parth Malwankar, #262450)
1190
* ``bzr upgrade`` now names backup directory as ``backup.bzr.~N~`` instead
1191
of ``backup.bzr``. This directory is ignored by bzr commands such as
1193
(Parth Malwankar, #335033, #300001)
1195
* Cope with non-utf8 characters inside ``.bzrignore``.
1196
(Jason Spashett, #183504)
1198
* Correctly interpret "451 Rename/move failure: Directory not empty" from
1199
FTP servers while trying to take a lock.
1200
(Martin Pool, #528722)
1202
* DirStateRevisionTree.kind() was returning wrong result when 'kind'
1203
changes occured between the workingtree and one of its parents.
1204
(Vincent Ladeuil, #535547)
1206
* Fix ``log`` to better check ancestors even if merged revisions are involved.
1207
(Vincent Ladeuil, #476293)
1209
* Loading a plugin from a given path with ``BZR_PLUGINS_AT`` doesn't depend
1210
on os.lisdir() order and is now reliable.
1211
(Vincent Ladeuil, #552922).
1213
* Many IO operations that returned ``EINTR`` were retried even if it
1214
wasn't safe to do so via careless use of ``until_no_eintr``. Bazaar now
1215
only retries operations that are safe to retry, and in some cases has
1216
switched to operations that can be retried (e.g. ``sock.send`` rather than
1218
(Andrew Bennetts, Martin <gzlist@googlemail.com>, #496813)
1220
* Path conflicts now support --take-this and --take-other even when a
1221
deletion is involved.
1222
(Vincent Ladeuil, #531967)
1224
* Network transfer amounts and rates are now displayed in SI units according
1225
to the Ubuntu Units Policy <https://wiki.ubuntu.com/UnitsPolicy>.
1226
(Gordon Tyler, #514399)
1228
* Support kind markers for socket and fifo filesystem objects. This
1229
prevents ``bzr status --short`` from crashing when those files are
1230
present. (John Arbash Meinel, #303275)
1232
* ``bzr mkdir DIR`` will not create DIR unless DIR's parent is a versioned
1233
directory. (Parth Malwankar, #138600)
1235
* SSH child processes will now ignore SIGQUIT on nix systems so breaking into
1236
the debugger won't kill the session.
1237
(Martin <gzlist@googlemail.com>, #162502)
1239
* Tolerate patches with leading noise in ``bzr-handle-patch``.
1240
(Toshio Kuratomi, Martin Pool, #502076)
1242
* ``update -r`` now supports updating to revisions that are not on
1243
mainline (i.e. it supports dotted revisions).
1244
(Parth Malwankar, #517800)
1246
* Use first apparent author not committer in GNU Changelog format.
1247
(Martin von Gagern, #513322)
1252
* ``bzrlib.merge_directive._BaseMergeDirective`` has been renamed to
1253
``bzrlib.merge_directive.BaseMergeDirective`` and is now public.
1256
* ``BranchFormat.initialize`` now takes an optional ``name`` of the colocated
1257
branch to create. (Jelmer Vernooij)
1259
* ``BzrDir.get_branch_transport`` now takes an optional ``name`` of the
1260
colocated branch to open. (Jelmer Vernooij)
1262
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
1263
can set a signal handler and call ``signal.siginterrupt(signum,
1264
False)`` for it, if the platform and Python version supports it.
1265
(Andrew Bennetts, #496813)
1267
* New ``bzrlib.initialize`` is recommended for programs using bzrlib to
1268
run when starting up; it sets up several things that previously needed
1269
to be done separately.
1270
(Martin Pool, #507710)
1272
* Exporters now support a ``per_file_timestamps`` argument to write out the
1273
timestamp of the commit in which a file revision was introduced.
1276
* New method ``BzrDir.list_branches()`` that returns a sequence of branches
1277
present in a control directory. (Jelmer Vernooij)
1279
* New method ``Repository.get_known_graph_ancestry()``.
1280
(Jelmer Vernooij, #495502)
1282
* New transport methods ``readlink``, ``symlink`` and ``hardlink``.
1285
* Remove unused ``CommandFailed`` exception.
1291
* ``bzrlib.branchbuilder.BranchBuilder.build_snapshot`` now accepts a
1292
``message_callback`` in the same way that commit does. (Robert Collins)
1294
* ``bzrlib.builtins.Commit.run`` raises ``bzrlib.errors.BoundBranchOutOfDate``
1295
rather than ``bzrlib.errors.BzrCommandError`` when the bound branch is out
1296
of date. (Gary van der Merwe)
1298
* ``bzrlib.commands.run_bzr`` is more extensible: callers can supply the
1299
functions to load or disable plugins if they wish to use a different
1300
plugin mechanism; the --help, --version and no-command name code paths
1301
now use the generic pluggable command lookup infrastructure.
1304
* ``bzrlib.errors.BoundBranchOutOfDate`` has a new field ``extra_help``
1305
which can be set to add extra help to the error. (Gary van der Merwe)
1307
* New method ``Branch.automatic_tag_name`` that can be used to find the
1308
tag name for a particular revision automatically. (Jelmer Vernooij)
1310
* The methods ``BzrDir.create_branch()``, ``BzrDir.destroy_branch()`` and
1311
``BzrDir.open_branch()`` now take an optional ``name`` argument.
1317
* bzr now has a ``.testr.conf`` file in its source tree configured
1318
appropriately for running tests with Testrepository
1319
(``https://launchpad.net/testrepository``). (Robert Collins)
1321
* Documentation about testing with ``subunit`` has been tweaked.
1324
* Known failures has been added for resolve --take-other on ParentLoop
1325
conflicts. This reflects bug #537956 without fixing it.
1328
* New ``bzrlib.tests.test_import_tariff`` can make assertions about what
1329
Python modules are loaded, to guard against startup time or library
1330
dependency regressions.
1333
* PQM will now run with subunit output. To analyze a PQM error use
1334
tribunal, or cat log | subunit-filter | subunit2pyunit. (Robert Collins)
1336
* Stop sending apport crash files to ``.cache`` in the directory from
1337
which ``bzr selftest`` was run. (Martin Pool, #422350)
1339
* Tests no longer fail if "close() called during concurrent
1340
operation on the same file object" occurs when closing the log file
1341
(which can happen if a thread tries to write to the log file at the
1342
wrong moment). An warning will be written to ``stderr`` when this
1343
happens, and another warning will be written if the log file could not
1344
be closed after retrying 100 times. (Andrew Bennetts, #531746)
