:2.3b1: NOT RELEASED YET
17
* BzrError subclasses no longer support the name "message" to be used
18
as an argument for __init__ or in _fmt format specification as this
19
breaks in some Python versions. errors.LockError.__init__ argument
20
is now named "msg" instead of earlier "message".
21
(Parth Malwankar, #603461)
23
* `decode` parameter to get() method in FtpTransport and GioTransport classes
24
is deprecated. (Alexander Belchenko)
26
* `FileInWrongBranch` is deprecated in favour of `PathNotChild` and no
30
* `tree_files` and `internal_tree_files` are now deprecated in favor of
31
`WorkingTree.open_containing_paths`.
34
* `ControlDirFormat` and `ControlDir` have been split out of `BzrDirFormat`
35
and `BzrDir`, respectively. `ControlDirFormat`
36
and `ControlDir` should be used as the base classes for new non-.bzr
39
`BzrDirFormat.register_control_format` has been renamed to
40
`ControlDirFormat.register_format`.
42
`BzrDirFormat.register_server_control_format` has been removed.
44
Probing for control directories is now done by separate objects derived
45
from `bzrlib.controldir.Prober` and registered using
46
`bzrlib.controldir.ControlDirFormat.register_prober` or
47
`bzrlib.controldir.ControlDirFormat.register_server_prober`.
48
`BzrDirFormat.probe_transport` has been moved onto `Prober`.
50
`BzrDirFormat.register_format` has been renamed to
51
`BzrProber.register_bzrdir_format`.
54
* The old ``bzr selftest --benchmark`` option has been removed.
55
<https://launchpad.net/bzr-usertest> is an actively-maintained
62
* ``bzr break-lock --config [location]`` can now break config files
63
locks. (Vincent Ladeuil, #525571)
65
* ``bzrlib.config.LockableConfig`` is a base class for config files that
66
needs to be protected against multiple writers. All methods that
67
change a configuration variable value must be decorated with
68
@needs_write_lock (set_option() for example).
69
(Vincent Ladeuil, #525571)
71
* The ``lp:`` prefix will now use your known username (from
72
``bzr launchpad-login``) to expand ``~`` to your username. For example:
73
``bzr launchpad-login user && bzr push lp:~/project/branch`` will now
74
push to ``lp:~user/project/branch``. (John Arbash Meinel)
79
* Allow using both --using and --diff-options.
80
(Matthäus G. Chajdas, #234708)
82
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
83
previously-unversioned directory within the tree: the directory is
85
(Martin Pool, #192859)
87
* ``bzr ignore PATTERNS`` exits with error if a bad pattern is supplied.
88
``InvalidPattern`` exception error message now shows faulting
90
(Parth Malwankar #300062)
92
* ``clean-tree`` issues a warning if it is unable to delete a file
93
due to ``errno.EACCES`` instead of exiting with an error on Windows.
94
(Parth Malwankar, #430785)
96
* CommitBuilder now uses the committer instead of _config.username to generate
97
the revision-id. (Aaron Bentley, #614404)
99
* Configuration files in ``${BZR_HOME}`` are now protected against
100
concurrent writers by using a lock. (Vincent Ladeuil, #525571)
102
* Cope with Microsoft FTP Server and VSFTPd that return reply '250
103
Directory created' when mkdir succeeds. (Martin Pool, #224373)
105
* Decrease peak memory during ``bzr send``. The old code was caching all
106
text content and all inventory strings for all revisions before
107
computing the diffs. Now we only cache as long as there is a child that
108
will need them. Sending 2000 bzr revisions drops from 1.2GB peak to
109
256MB peak. (John Arbash Meinel, #614576)
111
* Don't print internal object name when print an invalid revision spec
112
error. (Neil Martinsen-Burrell, #598701)
114
* ``EPIPE`` can be raised during test server shutdown. This happened on
115
gentoo only so far. (Vincent Ladeuil, #627277)
117
* Errors occurring during http(s) test server starts should now be
118
handled cleanly. (Vincent Ladeuil, #392402)
120
* Fix ``AttributeError on parent.children`` when adding a file under a
121
directory that was a symlink in the previous commit.
122
(Martin Pool, #192859)
124
* Fix spurious paramiko warning on hardy by ensuring that ``selftest``
125
properly remove its warning filter. (Vincent Ladeuil, #625686)
127
* ``HTTP/1.1`` test servers now set a ``Content-Length`` header to comply
128
with pedantic ``HTTP/1.1`` clients. (Vincent Ladeuil, #568421)
130
* Most of the leaked threads during selftest are now fixed, allowing the
131
full test suite to pass on gentoo.
132
(Vincent Ladeuil, #392127)
134
* `PathNotChild` should not give a traceback.
135
(Martin Pool, #98735)
137
* ``PQM`` will no longer ignore syntax errors in submissions.
138
(Vincent Ladeuil, #626667)
140
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
141
which can result in "missing referenced chk root keys" errors when
142
fetching from repositories with affected revisions.
143
(Andrew Bennetts, #522637)
145
* ``Transport.stat`` on a symlink, including a transport pointing directly
146
to a symlink, now returns information about the symlink.
152
* ``bzr remove`` now just backs up changed files instead of exiting,
153
forcing you to choose to either keep or delete them. Bazaar will now delete
154
the files if they can easily be recovered using revert, otherwise they
155
will be backed up (adding an extention of the form .~#~).
156
(Marius Kruger, #400554)
158
* ``bzr revert`` and ``bzr status`` are up to 15% faster on large trees
159
with many changes by not repeatedly building a list of all file-ids.
162
* Decrease memory consumption when many chk index pages are loaded. (Such
163
as during ``bzr co`` or ``bzr ls -R`` of a large tree.) Often we need to
164
read many chk pages because the individual chk map nodes will be spread
165
randomly. Peak memory for 'bzr ls -R' on a large tree dropped from 396MB
166
down to 247MB, expect even more significant savings on 64-bit platforms.
169
* ``DirState`` internals use a little bit less memory. For bzr.dev it
170
drops the memory from 1MB down to about 800kB. And replaces a few
171
thousand tuples and sets with StaticTuple. (John Arbash Meinel)
173
* Inventory entries now consume less memory (on 32-bit Ubuntu file entries
174
have dropped from 68 bytes to 40, and directory entries from 120 bytes
175
to 48). (Andrew Bennetts)
177
* When building new working trees, default to reading from the repository
178
rather than the source tree unless explicitly requested. (via
179
``--files-from`` and ``--hardlink`` for ``bzr branch`` and
180
``bzr checkout``. Generally, 2a format repositories extract
181
content faster than seeking and reading content from another tree,
182
especially in cold-cache situations. (John Arbash Meinel, #607298)
187
* Added a builder/writer sphinx extension that can generate texinfo files. The
188
generated files are syntactically correct but the info navigation nodes
189
needs more work. (Vincent Ladeuil, #219334)
191
* First tests defined for sphinx, including a new bzrlib.tests.features.sphinx
192
to make the tests conditional.
195
* Fix a lot of references in the docs to the old http://bazaar-vcs.org to
196
the new http://bazaar.canonical.com or http://wiki.bazaar.canonical.com
197
(John Arbash Meinel, #617503)
202
* Configuration files should now use the ``from_string`` constructor rather
203
than the ``file`` parameter of the ``_get_parser`` method. The later has
204
been deprecated. ``from_string`` also accept a ``save=True`` parameter to
205
have the configuration file immediately written to disk.
208
* ``IniBaseConfig`` objects should now use the ``from_string`` constructor
209
the rather than the ``file`` parameter of the ``_get_parser`` method. The
210
later has been deprecated. (Vincent Ladeuil)
212
* InventoryEntry instances now raise AttributeError if you try to assign
213
to attributes that are irrelevant to that kind of entry. e.g. setting
214
``symlink_target`` on an InventoryFile will fail. It is still okay to
215
read those attributes on any kind of InventoryEntry. The complete list
216
of affected attributes is: ``executable``, ``text_id``, ``text_sha1``,
217
``text_size`` (only valid for kind == file); ``symlink_target`` (only
218
valid for kind == link); and ``reference_revision`` (only valid for kind
219
== tree-reference). (Andrew Bennetts)
221
* InventoryEntry objects no longer have ``_put_in_tar`` or
222
``_put_on_disk`` methods. (Andrew Bennetts)
224
* The ``get_filename`` parameter in the ``config.IniBaseConfig``
225
constructor has been deprecated, use the ``file_name`` parameter instead.
231
* Remove used and broken code path in ``BranchInitHookParams.__repr__``.
237
* HTTP test servers will leak less threads (and sockets) and will not hang on
238
AIX anymore. (Vincent Ladeuil, #405745)
240
* The way ``bzr selftest --parallel`` generates N partitions of tests to
241
run in parallel has changed. Instead of splitting the list of tests at
242
N-1 points, it distributes the tests one-by-one into the partitions in a
243
round robin fashion. This reduces the total time to run the tests in
244
parallel because a series of slow tests in the test suite will be
245
distributed evenly among the parallel test suites, rather than slowing
246
down just one suite. (Andrew Bennetts)
253
:2.2.1: NOT RELEASED YET
258
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
259
previously-unversioned directory within the tree: the directory is
260
marked versioned too.
261
(Martin Pool, #192859)
263
* CommitBuilder now uses the committer instead of _config.username to generate
264
the revision-id. (Aaron Bentley, #614404)
266
* Cope with Microsoft FTP server that returns reply '250 Directory
267
created' when mkdir succeeds. (Martin Pool, #224373)
269
* Fix ``AttributeError on parent.children`` when adding a file under a
270
directory that was a symlink in the previous commit.
271
(Martin Pool, #192859)
276
* Fix a lot of references in the docs to the old http://bazaar-vcs.org to
277
the new http://bazaar.canonical.com or http://wiki.bazaar.canonical.com
278
(John Arbash Meinel, #617503)
283
* Remove used and broken code path in ``BranchInitHookParams.__repr__``.
293
This release marks the start of another long-term-stable series. From
294
here, we will only make bugfix releases on the 2.2 series (2.2.1, etc),
295
while 2.3 will become our new development series. The 2.0 and 2.1 series
296
will also continue to get bugfixes. (Currently 2.0 is planned to be
297
supported for another 6 months.)
299
This is primarily a bugfix and polish release over the 2.1 series, with
300
a large number of bugs fixed (>120), and some performance improvements.
302
There are some compatibility changes in this release. For users of bzrlib
303
as a library, we now request that they call ``bzrlib.initialize`` and use
304
the returned context manager appropriately. For commandline users we no
305
longer guess user identity for ``bzr commit``, users must specify their
306
identity using ``bzr whoami`` (you don't need to specify your identity for
307
readonly operations).
309
Users are encouraged to upgrade from the other stable series.
314
* BzrError subclasses no longer support the name "message" to be used
315
as an argument for __init__ or in _fmt format specification as this
316
breaks in some Python versions. errors.LockError.__init__ argument
317
is now named "msg" instead of earlier "message".
318
(Parth Malwankar, #603461)
320
* The old ``bzr selftest --benchmark`` option has been removed.
321
<https://launchpad.net/bzr-usertest> is an actively-maintained
322
macrobenchmark suite.
328
* ``bzr ignore PATTERNS`` exits with error if a bad pattern is supplied.
329
``InvalidPattern`` exception error message now shows faulting
331
(Parth Malwankar #300062)
333
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
334
way which should help avoid problems with concurrent writers.
335
(Vincent Ladeuil, #525571)
337
* Don't traceback trying to unversion children files of an already
338
unversioned directory. (Vincent Ladeuil, #494221)
340
* ``HTTP/1.1`` test servers now set a ``Content-Length`` header to comply
341
with pedantic ``HTTP/1.1`` clients. (Vincent Ladeuil, #568421)
343
* Progress bars prefer to truncate the text message rather than the
344
counters. The spinner is shown between the network transfer indicator
345
and the progress message. Progress bars are correctly cleared off when
346
they finish. (Martin Pool, #611127)
348
* Recursive binding for checkouts is now detected by bzr. A clear error
349
message is shown to the user. (Parth Malwankar, #405192)
354
* Add ``bzrlib.merge.MergeIntoMerger``, which can merge part or all of a
355
tree, and works with unrelated branches. (Andrew Bennetts)
357
* Add py2exe windows target ``bzrw.exe``. This allow for starting a Bazaar
358
GUI with out have a console open in the background.
359
(Gary van der Merwe, #433781)
364
* ``bzr help patterns`` now explains case insensitive patterns and
365
points to Python regular expression documentation.
366
(Parth Malwankar, #594386)
371
* Delete ``ProgressTask.note``, which was deprecated in 2.1.
376
* Unit test added to ensure that "message" is not uses as a format variable
377
name in BzrError subclasses as this conflicts with some Python versions.
378
(Parth Malwankar, #603461)
383
:Codename: Monkey Magic
387
This fourth and final beta in the 2.2 series now stabilizes the internal
388
APIs. Plugin authors are recommended to ensure their releases are
389
compatible, so that 2.2rc1 can be a true release candidate, containing
390
stable and compatible plugin versions.
392
For users of bzrlib as a library, one of the primary changes is to request
393
that they call ``bzrlib.initialize`` and use the returned context manager
396
Better interaction with ``bzr-loom`` to make sure branching from a loom
397
even over a smart server still yields a local loom. Not to mention lots of
403
* bzrlib library users now need to call ``__enter__`` and ``__exit__`` on
404
the result of ``bzrlib.initialize``. This change was made when fixing
405
the bad habit recent bzr versions have had of leaving progress bars
406
behind on the screen. That required calling another function before
407
exiting the program, and it made sense to provide a full context
408
manager at the same time. (Robert Collins)
410
* The ``bzr`` front end now requires a ``bzrlib.ui.ui_factory`` which is a
411
context manager in the Python 2.5 and above sense. The bzrlib base class
412
is such a manager, but third party UI factories which do not derive from
413
``bzrlib.ui.UIFactory`` will be incompatible with the command line front
416
* URLs like ``foo:bar/baz`` are now always parsed as a URL with scheme "foo"
417
and path "bar/baz", even if bzr does not recognize "foo" as a known URL
418
scheme. Previously these URLs would be treated as local paths.
425
* Support ``--directory`` option for a number of additional commands:
426
conflicts, merge-directive, missing, resolve, shelve, switch,
427
unshelve, whoami. (Martin von Gagern, #527878)
432
* ``bzr branch`` to a new repository with a default stacking policy no
433
longer transfers the full history unnecessarily.
434
(Andrew Bennetts, #597942)
436
* ``bzr init`` does not recursively scan directory contents anymore
437
leading to faster init for directories with existing content.
438
(Martin [gz], Parth Malwankar, #501307)
440
* ``bzr log --exclude-common-ancestry`` is now taken into account for
441
linear ancetries. (Vincent Ladeuil, #575631)
443
* ``bzr log -r branch:REMOTE`` can now properly log the remote branch,
444
rather than trying to fetch the data locally and failing because of a
445
readonly error. (Martin von Gagern, #149270)
447
* ``bzr pull`` now works when a lp: URL is explicitly defined as the parent
448
or pull location in locations.conf or branch.conf.
449
(Gordon Tyler, #534787)
451
* ``bzr reconfigure --unstacked`` now works with branches accessed via a
452
smart server. (Andrew Bennetts, #551525)
454
* ``BzrDir.find_branches`` should ignore branches with missing repositories.
455
(Marius Kruger, Robert Collins)
457
* ``BzrDir.find_bzrdirs`` should ignore dirs that raises PermissionDenied.
458
(Marius Kruger, Robert Collins)
460
* Ensure that wrong path specifications in ``BZR_PLUGINS_AT`` display
461
proper error messages. (Vincent Ladeuil, #591215)
463
* Explicitly removing ``--profile-imports`` option from parsed command-line
464
arguments on Windows, because bzr script does the same.
465
(Alexander Belchenko, #588277)
467
* Fetching was slightly confused about the best code to use and was
468
using a new code path for all branches, resulting in more lookups than
469
necessary on old branches. (Robert Collins, #593515)
471
* Final fix for 'no help for command' issue. We now show a clean message
472
when a command has no help, document how to set help more clearly, and
473
test that all commands available to the test suite have help.
474
(Robert Collins, #177500)
476
* Invalid patterns supplied to ``Globster`` or ``lazy_regex`` now raise
477
``InvalidPattern`` exception showing clear error message to the user.
478
(Parth Malwankar #300062)
480
* Progress output is cleaned up when exiting. (Aaron Bentley)
482
* Raise ValueError instead of a string exception.
483
(John Arbash Meinel, #586926)
485
* Relative imports in plugins are now handled correctly when using
486
BZR_PLUGINS_AT. (Vincent Ladeuil, #588959)
488
* ``ScriptRunner`` now strips off leading indentation from test scripts,
489
which previously caused "SyntaxError: No command for line".
492
* Show unicode filenames in diff headers using terminal encoding.
493
(Alexander Belchenko, Bug #382699)
494
NOTE for Windows users: If user need to save diff to file then user need to
495
change encoding of the terminal to ANSI encoding with command ``chcp XXX``
496
(e.g. ``chcp 1251`` for Russian Windows).
498
* URL displayed for use with ``break-lock`` when smart server sees lock
499
contention are now valid. Default timeout for lock contention retry is
500
now 30 seconds instead of 300 seconds.
501
(Parth Malwankar, #250451)
503
* ``walkdirs`` now raises a useful message when the filenames are not using
504
the filesystem encoding. (Eric Moritz, #488519)
506
* Enable debugging of bzr on windows with pdb and other tools. This was
507
broken because we call GetCommandLineW on windows. The fix adjusts the
508
command line we get to be the same length as sys.argv.
509
(Jason Spashett, Alexander Belchenko, #587868)
514
* Bazaar now reads data from SSH connections more efficiently on platforms
515
that provide the ``socketpair`` function, and when using paramiko.
516
(Andrew Bennetts, #590637)
518
* ``Branch.copy_content_into`` is now a convenience method dispatching to
519
a ``InterBranch`` multi-method. This permits ``bzr-loom`` and other
520
plugins to intercept this even when a ``RemoteBranch`` proxy is in use.
521
(Robert Collins, #201613)
523
* ``Branch`` formats can now be loaded lazily by registering a
524
``MetaDirBranchFormatFactory`` rather than an actual format. This will
525
cause the named format class to be loaded only when an enumeration of
526
formats is needed or when the format string for the object is
527
encountered. (Robert Collins, Jelmer Vernooij)
529
* The encoding that bzr uses to output things other than file content can
530
now be overridden via the output_encoding configuration option.
531
(Martin Pool, #340394)
533
* Use lazy imports in ``bzrlib/merge.py`` so that plugins like ``news_merge``
534
do not cause modules to be loaded unnecessarily just because the plugin
535
registers a merge hook. This improves ``bzr rocks`` time by about 25%
536
in a default installation (with just the core plugins).
542
* Added ``regression`` tag to our tags list. (Robert Collins)
544
* Improved our release checklist to have a bit less churn and leave things
545
ready-to-go for the next action (including other people doing
546
development). (Robert Collins)
548
* Remove obsolete discussion of PQM in documentation about how to
549
contribute to Bazaar. (Martin Pool, #588444)
554
* ``bzrlib.branch.InterBranch._get_branch_formats_to_test`` now returns
555
an iterable of format pairs, rather than just a single pair, permitting
556
InterBranch objects that work with multiple permutations to be
557
comprehensively tested. (Robert Collins)
559
* ``bzrlib.lsprof.profile`` will no longer silently generate bad threaded
560
profiles when concurrent profile requests are made. Instead the profile
561
requests will be serialised. Reentrant requests will now deadlock.
564
* ``bzrlib.knit.KnitSequenceMatcher``, which has been deprecated since
565
2007, has been deleted. Use ``PatienceSequenceMatcher`` from
566
``bzrlib.patiencediff`` instead. (Andrew Bennetts)
568
* ``bzrlib.re_compile_checked`` is now deprecated. Caller should handle
569
``bzrlib.errors.InvalidPattern`` exception thrown by ``re.match`` in
570
case the default error message not suitable for the use case.
573
* ``bzrlib.tests.blackbox.ExternalBase`` is deprecated. It provided only
574
one method ``check_output``, and we now recommend checking command
575
output using ``run_script``. (Martin Pool)
577
* ``bzrlib.transport.ssh.SSHVendor.connect_ssh`` now returns an object
578
that implements the interface of ``bzrlib.transport.ssh.SSHConnection``.
579
Third-party implementations of ``SSHVendor`` may need to be updated
580
accordingly. Similarly, any code using ``SSHConnection`` directly will
581
need to be updated. (Andrew Bennetts)
583
* The constructor of ``bzrilb.smart.medium.SmartSSHClientMedium`` has
584
changed to take an ``SSHParams`` instance (replacing many individual
585
values). (Andrew Bennetts)
590
* ``bzrlib.osutils.get_terminal_encoding`` will now only mutter its
591
selection when explicitly requested; this avoids many duplicate calls
592
being logged when helpers, wrappers and older code that manually calls
593
it are executed it is now logged deliberately by the ui setup code.
596
* Improved ``bzrlib.urlutils`` to handle lp:foo/bar URLs. (Gordon Tyler)
598
* ``bzrlib._c_static_tuple.StaticTuple`` now implements ``__sizeof__``, so
599
that ``sys.getsizeof`` and other memory analysis tools will report more
600
accurate results. (Andrew Bennetts)
602
* The symbol_versioning module can now cleanup after itself -
603
``suppress_deprecation_warnings`` now returns a cleanup function.
609
* Add ``bzrlib.tests.fixtures`` to hold code for setting up objects
610
to test. (Martin Pool)
612
* ``test_import_tariff`` now respects BZR_PLUGINS_AT and BZR_PLUGINS_DISABLE.
613
(Vincent Ladeuil, #595587)
620
This third beta in the 2.2 series brings with it all the goodness of 2.1.2
621
and 2.0.6 (though it preceeds 2.0.6 slightly). Of particular note for
622
users are compatibility fixes with bzr 1.5 and below servers, a hopeful
623
end to the EINTR errors caused by SIGWINCH interactions, a shiny new
624
bash completion script and bzr will no longer guess at identity details -
625
it was too unreliable in reality. Use ``bzr whoami`` on every new install.
626
For developers we have some API changes which may impact plugins as well
627
as a bunch of our regular improvements to internal clarity and test
633
* An API break has been made to the lock_write method of ``Branch`` and
634
``Repository`` objects; they now return ``branch.BranchWriteLockResult``
635
and ``repository.RepositoryWriteLockResult`` objects. This makes
636
changing the API in future easier and permits some cleaner calling code.
637
The lock_read method has also changed from having no defined return
638
value to returning ``LogicalLockResult`` objects.
641
* ``bzr`` does not try to guess the username as ``username@hostname``
642
and requires it to be explictly set. This can be set using ``bzr
643
whoami``. (Parth Malwankar, #549310)
645
* ``bzrlib.commands.Command`` will now raise ValueError during
646
construction if there is no __doc__ set. (Note, this will be reverted in
647
2.2b4) (Robert Collins)
649
* The source tree no longer contains a contrib/zsh/_bzr completion
650
script. The new file contrib/zsh/README suggests alternatives.
651
(Martin von Gagern, #560030)
656
* ``bzr commit`` accepts ``-p`` (for "patch") as a shorter name for
658
(Parth Malwankar, #571467)
660
* ``bzr ignore`` now supports a ``--default-rules`` option that displays
661
the default ignore rules used by bzr. The flag ``--old-default-rules``
662
is no longer supported by ``ignore``.
663
(Parth Malwankar, #538703)
665
* ``bzr pack`` now supports a ``--clean-obsolete-packs`` option that
666
can save disk space by deleting obsolete pack files created during the
668
(Parth Malwankar, #304320)
670
* New command line option ``--authors`` to ``bzr log`` allows users to
671
select which of the apparent authors and committer should be
672
included in the log. Defaults depend on format. (Martin von Gagern, #513322)
674
* Support ``--directory`` option for a number of additional commands:
675
added, annotate, bind, cat, cat-revision, clean-tree, deleted,
676
export, ignore, ignored, lookup-revision, ls, modified, nick,
677
re-sign, unbind, unknowns.
678
(Martin von Gagern, #527878)
680
* The bash_completion plugin from the bzr-bash-completion project has
681
been merged into the tree. It provides a bash-completion command and
682
replaces the outdated ``contrib/bash/bzr`` script with a version
683
using the plugin. (Martin von Gagern, #560030)
685
* A new transport based on GIO (the gnome i/o library) provides access to
686
samba shares, webdav using gio+smb and gio+dav. It is also possible to
687
use gio for some already existing transport methods as gio+file,
694
* Alias information shown by ``bzr help`` is now accurate. This
695
was showing an internal object name for some plugin aliases.
696
(Parth Malwankar, #584650)
698
* ``.bazaar``, ``.bazaar/bazaar.conf`` and ``.bzr.log`` inherit user and
699
group ownership from the containing directory. This allow bzr to work
701
(Martin <gzlist@googlemail.com>, Parth Malwankar, #376388)
703
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
704
support of bzr-externals and scmproj plugins.
705
(Alexander Belchenko, bug #572098)
707
* ``bzr ignore`` will no longer add duplicate patterns to .bzrignore.
708
(Gordon Tyler, #572092)
710
* ``bzr log --exclude-common-ancestry -r X..Y`` displays the revisions that
711
are part of Y ancestry but not part of X ancestry (aka the graph
713
(Vincent Ladeuil, #320119)
715
* ``bzr lp-propose`` which was switched to use production Launchpad API
716
servers a few commits ago has been reverted to use edge: there is a
717
problem with using production which isn't trivially obvious, so we've
718
filed a bug to track it, and until thats fixed will be using edge.
719
(Robert Collins, #583667)
721
* ``bzr rm`` should not refuse to delete directories which contained a file
722
which has been moved elsewhere in the tree after the previous commit.
723
(Marius Kruger, Daniel Watkins, #129880)
725
* ``bzr selftest --parallel=fork`` wait for its children avoiding zombies.
726
(Vincent Ladeuil, #566670)
728
* ``bzr selftest`` should not use ui.note() since it's not unicode safe.
729
(Vincent Ladeuil, #563997)
731
* CommitBuilder refuses to create revisions whose trees have no root.
734
* Do not register a SIGWINCH signal handler, instead just poll for the
735
terminal width as needed. This avoids the "Interrupted System Call"
736
problems that occur on POSIX with all currently released versions of
738
(Andrew Bennetts, #583941)
740
* Don't mention --no-strict when we just issue the warning about unclean trees.
741
(Vincent Ladeuil, #401599)
743
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
745
(Andrew Bennetts, #528041)
747
* Improved progress bar for fetch (2a format only). Bazaar now shows an
748
estimate of the number of records to be fetched vs actually fetched.
749
(Parth Malwankar, #374740, #538868)
751
* Reduce peak memory by one copy of compressed text.
752
(John Arbash Meinel, #566940)
754
* ``RemoteBranch.lock_write`` raises ``ReadOnlyError`` if called during a
755
read lock, rather than causing an ``AttributeError``.
756
(Andrew Bennetts, Данило Шеган, #582781)
758
* Selftest was failing with testtools 0.9.3, which caused an
759
AssertionError raised from a cleanUp to be reported as a Failure, not an
760
Error, breaking on of our test hygiene tests.
761
(Robert Collins, Vincent Ladeuil).
763
* ``set_user_option`` with a dict on remote branches no longer fails with
764
an AttributeError. There is a new ``Branch.set_config_option_dict`` RPC
765
to support this efficiently.
766
(Andrew Bennetts, #430382)
768
* Show the filenames when a file rename fails so that the error will be
770
(Martin Pool, #491763)
772
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
773
(John Arbash Meinel, #582656)
775
* Unicode characters in aliases are now handled correctly and do not cause
776
UnicodeEncodeError exception. (Parth Malwankar, #529930)
778
* Unicode commit messages that are the same as a file name no longer cause
779
UnicodeEncodeError. ``ui.text.show_warning`` now handles unicode
781
(Parth Malwankar, #563646)
783
* Using bzr with `lp:` urls behind an http proxy should work.
784
(Robert Collins, #558343)
786
* When passing a file to ``UTF8DirReader`` make sure to close the current
787
directory file handle after the chdir fails. Otherwise when passing many
788
filenames into a command line ``bzr status`` we would leak descriptors.
789
(John Arbash Meinel, #583486)
794
* ``append_revisions_only`` will now be interpreted as a boolean and a
795
warning emitted if illegal values are used. Note that for projects
796
that needs to maintain compatibility with previsous bzr versions,
797
only 'True' and 'False' strings must be used (previous versions of
798
bzr will interpret all strings differing from 'True'
799
(case-sensitive) as false.
800
(Brian de Alwis, Vincent Ladeuil)
802
* ``bzr ls`` now supports short options for existing long options.
803
``-k/--kind``, ``-i/--ignored``, ``-u/--unknown`` and ``-0/--null``.
804
(Parth Malwankar, #181124)
806
* ``Config.get_user_option_as_bool`` will now warn if a value cannot
807
be interpreted as a boolean.
810
* The all-in-one Windows installer will now be built with docstrings stripped
811
from the library zip, reducing the size and slightly improving cold startup
812
time. Bundled plugins are unchanged for the moment, but if adding other new
813
plugins to an all-in-one installation, ensure they are compiled and
814
installed with -O1 or help may not work. (Martin [gz])
819
* Added ``bzrlib.merge.PerFileMerger``, a more convenient way to write
820
some kinds of ``merge_file_content`` hook functions.
823
* `BzrDir`, `Branch`, `Repository` and `WorkingTree` now all support `user_url`,
824
`user_transport`, `control_url` and `control_transport` members pointing
825
respectively to the directory containing the ``.bzr`` control directory,
826
and to the directory within ``.bzr`` used for the particular component.
827
All of them inherit from `ControlComponent` which provides default
831
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
832
expected to return an object which can be used to unlock them. This reduces
833
duplicate code when using cleanups. The previous 'tokens's returned by
834
``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
835
on the result of the lock_write. ``repository.RepositoryWriteLockResult``
836
and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
838
* ``Repository.refresh_data`` may now be called in a write group on
839
pack-based repositories. Older repositories will still raise an error
840
in this case. Subclasses of ``Repository`` can still override
841
``Repository._refresh_data``, but are now responsible for raising
842
``bzrlib.repository.IsInWriteGroupError`` if they do not support
843
``refresh_data`` during a write group.
844
(Andrew Bennetts, #574236)
849
* ``chk_map._bytes_to_text_key`` is now an optimized function to extract
850
the (file-id, revision-id) key from a CHKInventory entry. This can
851
potentially shave 5-10% time off during a large fetch. Related to bug
852
#562666. (John Arbash Meinel)
854
* ``log._get_info_for_log_files`` now takes an add_cleanup callable.
857
* ``_remember_remote_is_before`` no longer raises AssertionError when
858
suboptimal network behaviour is noticed; instead it just mutters to the
859
log file (and warns the user if they have set the ``hpss`` debug flag).
860
This was causing unnecessary aborts for performance bugs that are minor
862
(Andrew Bennetts, #528041)
864
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
865
files loaded from disk. To ensure docstrings needed for help are never
866
stripped, the prefix ``__doc__ =`` should now be used.
867
(Martin <gzlist@googlemail.com>)
869
* No longer require zlib headers to build extensions, and remove the need
870
for seperate copy of zlib library on windows.
871
(John Arbash Meinel, Martin <gzlist@googlemail.com>, #566923)
876
* Added ``bzrlib.tests.matchers`` as a place to put matchers, along with
877
our first in-tree matcher. See the module docstring for details.
880
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
881
(Gordon Tyler, #551332)
883
* Workaround ``Crypto.Random`` check leading to spurious test
884
failures on Lucid, FreeBSD and gentoo.
885
(Vincent Ladeuil, #528436)
887
* New class ``ExecutableFeature`` for checking the availability of
888
executables on the ``PATH``. Migrated from bash_completion plugin.
896
This is a somewhat early second beta of the 2.2 series, to fix a python2.4
897
incompatibility in the 2.2b1 release. It also includes a swag of
898
performance, usability and correctness improvements: test feedback on all
899
of these would be welcome.
905
* ``bzr diff`` now supports a --format option, which can be used to
906
select alternative diff formats. (Jelmer Vernooij, #555994)
911
* ``bzr dpush``, ``bzr push`` and ``bzr send`` will now issue a warning
912
instead of failing when dirty trees are involved. The corresponding
913
``dpush_strict``, ``push_strict`` and ``send_strict`` should be set to
914
True explicitly to get the previous behaviour.
915
(Vincent Ladeuil, #519319)
917
* ``bzr export`` to tar file does not fail if any parent directory
918
contains unicode characters. This works around upstream Python bug
919
http://bugs.python.org/issue8396 .
920
(Parth Malwankar, #413406)
922
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
923
(Aaron Bentley, #559436)
925
* ``bzr update`` when a pending merge in the working tree has been merged
926
into the master branch will no longer claim that old commits have become
927
pending merges. (Robert Collins, #562079)
929
* ``bzrlib.mutabletree.MutableTree.commit`` will now support a passed in
930
config as in previous versions of bzrlib. (Robert Collins)
932
* Fix glitch in the warning about unclean trees display.
933
(Vincent Ladeuil, #562665)
935
* Fixed Python2.4 incompatibilities in the bzr2.2b1 source tarball.
938
* Help messages generated by ``RegistryOption.from_kwargs`` list the
939
switches in alphabetical order, rather than in an undefined order.
940
(Martin von Gagern, #559409)
942
* Make sure the ``ExecutablePath`` and ``InterpreterPath`` are set in
943
Apport crash reports, to avoid "This problem report applies to a program
944
which is not installed any more" error.
945
(Martin Pool, James Westby, #528114)
947
* Reset ``siginterrupt`` flag to False every time we handle a signal
948
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
949
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
950
errors compared to registering ``signal.signal`` directly.
953
* When invoked with a range revision, ``bzr log`` doesn't show revisions
954
that are not part of the Y revisions ancestry anymore when invoked with
956
(Vincent Ladeuil, #474807)
958
* Properly handle ``param_name`` attribute for ``ListOption``.
959
(Martin von Gagern, #387117)
964
* ``bzr commit`` will prompt before using a commit message that was
965
generated by a template and not edited by the user.
966
(Robert Collins, #530265)
968
* ``bzr diff`` read-locks the trees and branches only once, saving about
969
10-20ms on ``bzr diff`` in a bzr.dev tree.
972
* ``bzr missing`` read-locks the branches only once.
975
* ``bzr pull`` locks the branches and tree only once.
978
* Index lookups in pack repositories search recently hit pack files first.
979
In repositories with many pack files this can greatly reduce the
980
number of files accessed, the number of bytes read, and the number of
981
read calls. An incremental pull via plain HTTP takes half the time and
982
bytes for a moderately large repository. (Andrew Bennetts)
984
* Index lookups only re-order the indexes when the hit files aren't
985
already first. Reduces the cost of reordering
986
(John Arbash Meinel, #562429)
988
* Less code is loaded at startup. (Cold-cache start time is about 10-20%
990
(Martin Pool, #553017)
995
* ``bzrlib.diff.get_trees_and_branches_to_diff`` is deprecated. Use
996
``get_trees_and_branches_to_diff_locked`` instead.
999
* ``TreeTransform.commit`` supports the full set of commit parameters, and
1000
auto-determines branch nick if not supplied. (Aaron Bentley)
1005
* ``bzrlib.commands.Command.run_direct`` is no longer needed - the pre
1006
2.1 method of calling run() to perform testing or direct use via the API
1007
is now possible again. As part of this, the _operation attribute on
1008
Command is now transient and only exists for the duration of ``run()``.
1016
This is the first beta of the 2.2 series, leading up to a 2.2.0
1017
release in July or August. Beta releases are suitable for everyday use
1018
but may cause some incompatibilities with plugins. Some plugins may need
1019
small updates to work with 2.2b1.
1021
2.2b1 includes some changes to make merge conflicts easier to understand
1022
and resolve. It also removes some old unnecessary code, and loads
1023
somewhat less code at startup. It starts adding a common infrastructure
1024
for dealing with colocated named branches, which can be implemented in
1025
various ways in either bzr native or foreign formats. On Ubuntu and
1026
other platforms with the apport bug-reporting library, there's an easier
1027
path to report problems with bzr. We plan to continue with these themes
1028
through the 2.2 series.
1030
Over thirty bugs have been fixed, including in the log command, exporting
1031
to tarballs, restarting interrupted system calls, portability of compiled
1032
extensions, making backups during upgrade, and locking on ftp.
1034
Compatibility Breaks
1035
********************
1037
* BTreeGraphIndex can now take an offset to indicate that the data starts
1038
somewhere other than then beginning of the file. (John Arbash Meinel)
1040
* Deleted very old hidden commands ``versionedfile-list``,
1041
``weave-plan-merge``, ``weave-merge-text``.
1044
* ``Repository.get_inventory_sha1()`` and ``Repository.get_revision_xml()``
1045
have been removed. (Jelmer Vernooij)
1047
* ``Repository.get_revision_inventory()`` has been removed in favor of
1048
``Repository.get_inventory()``. (Jelmer Vernooij)
1050
* All test servers have been moved out of the bzrlib.transport hierarchy to
1051
bzrlib.tests.test_server *except* for MemoryServer, ChrootServer and
1052
PathFilteringServer. ``bzrlib`` users may encounter test failures that can
1053
be fixed by updating the related imports from ``bzrlib.transport.xxx`` to
1054
``bzrlib.tests.test_server``.
1057
* ``BranchReferenceFormat.initialize()`` now takes an optional name argument
1058
as its second parameter, for consistency with the initialize() method of
1059
other formats. (Jelmer Vernooij)
1064
* Added ``bzr remove-branch`` command that can remove a local or remote
1065
branch. (Jelmer Vernooij, #276295)
1067
* ``bzr export`` now takes an optional argument ``--per-file-timestamps``
1068
to set file mtimes to the last timestamp of the last revision in which
1069
they were changed rather than the current time. (Jelmer Vernooij)
1071
* If the Apport crash-reporting tool is available, bzr crashes are now
1072
stored into the ``/var/crash`` apport spool directory, and the user is
1073
invited to report them to the developers from there, either
1074
automatically or by running ``apport-bug``. No information is sent
1075
without specific permission from the user. (Martin Pool, #515052)
1077
* Parsing of command lines, for example in ``diff --using``, no longer
1078
treats backslash as an escape character on Windows. (Gordon Tyler,
1081
* Plugins can be disabled by defining ``BZR_DISABLE_PLUGINS`` as
1082
a list of plugin names separated by ':' (';' on windows).
1083
(Vincent Ladeuil, #411413)
1085
* Plugins can be loaded from arbitrary locations by defining
1086
``BZR_PLUGINS_AT`` as a list of name@path separated by ':' (';' on
1087
windows). This takes precedence over ``BZR_PLUGIN_PATH`` for the
1088
specified plugins. This is targeted at plugin developers for punctual
1089
needs and *not* intended to replace ``BZR_PLUGIN_PATH``.
1090
(Vincent Ladeuil, #82693)
1092
* Tag names can now be determined automatically by ``automatic_tag_name``
1093
hooks on ``Branch`` if they are not specified on the command line.
1096
* Tree-shape conflicts can be resolved by providing ``--take-this`` and
1097
``--take-other`` to the ``bzr resolve`` command. Just marking the conflict
1098
as resolved is still accessible via the ``--done`` default action.
1101
* Merges can be proposed on Launchpad with the new lp-propose-merge command.
1102
(Aaron Bentley, Jonathan Lange)
1107
* Added docstring for ``Tree.iter_changes``
1108
(John Arbash Meinel, #304182)
1110
* Allow additional arguments to
1111
``RemoteRepository.add_inventory_by_delta()``. (Jelmer Vernooij, #532631)
1113
* Allow exporting a single file using ``bzr export``.
1114
(Michal Junák, #511987)
1116
* Allow syscalls to automatically restart when ``TextUIFactory``'s
1117
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
1118
IO, which are often poorly handled by Python's libraries and parts of
1119
bzrlib. (Andrew Bennetts, #496813)
1121
* Avoid infinite recursion when probing for apport.
1122
(Vincent Ladeuil, #516934)
1124
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1125
(Martin Pool, #331095)
1127
* Avoid truncating svn URLs.
1128
(Martin Pool, Martin von Gagern, #545185)
1130
* ``bzr add`` will not add conflict related files unless explicitly required.
1131
(Vincent Ladeuil, #322767, #414589)
1133
* ``bzr dump-btree`` now works on ``*.cix`` and ``*.six`` files. Those
1134
indices do not have reference lists, so ``dump-btree`` will simply show
1135
``None`` instead. (Andrew Bennetts, #488607)
1137
* ``bzr help`` will no longer trigger the get_missing_command hook when
1138
doing a topic lookup. This avoids prompting (like 'no command plugins/loom,
1139
did you mean log?') when getting help. In future we may trigger the hook
1140
deliberately when no help topics match from any help index.
1141
(Robert Collins, #396261)
1143
* ``bzr log -n0 -r..A.B.C`` should not crash but just consider the None
1144
revspec as representing the first revision of the branch.
1145
(Vincent Ladeuil, #519862)
1147
* ``bzr remove-tree`` can now remove multiple working trees.
1148
(Jared Hance, Andrew Bennetts, #253137)
1150
* ``bzr resolve --take-this`` and ``--take-other`` now correctly renames
1151
the kept file on content conflicts where one side deleted the file.
1152
(Vincent Ladeuil, #529968)
1154
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
1155
permissions as ``.bzr`` directory on a POSIX OS.
1156
(Parth Malwankar, #262450)
1158
* ``bzr upgrade`` now names backup directory as ``backup.bzr.~N~`` instead
1159
of ``backup.bzr``. This directory is ignored by bzr commands such as
1161
(Parth Malwankar, #335033, #300001)
1163
* Cope with non-utf8 characters inside ``.bzrignore``.
1164
(Jason Spashett, #183504)
1166
* Correctly interpret "451 Rename/move failure: Directory not empty" from
1167
ftp servers while trying to take a lock.
1168
(Martin Pool, #528722)
1170
* DirStateRevisionTree.kind() was returning wrong result when 'kind'
1171
changes occured between the workingtree and one of its parents.
1172
(Vincent Ladeuil, #535547)
1174
* Fix ``log`` to better check ancestors even if merged revisions are involved.
1175
(Vincent Ladeuil, #476293)
1177
* Loading a plugin from a given path with ``BZR_PLUGINS_AT`` doesn't depend
1178
on os.lisdir() order and is now reliable.
1179
(Vincent Ladeuil, #552922).
1181
* Many IO operations that returned ``EINTR`` were retried even if it
1182
wasn't safe to do so via careless use of ``until_no_eintr``. Bazaar now
1183
only retries operations that are safe to retry, and in some cases has
1184
switched to operations that can be retried (e.g. ``sock.send`` rather than
1186
(Andrew Bennetts, Martin <gzlist@googlemail.com>, #496813)
1188
* Path conflicts now support --take-this and --take-other even when a
1189
deletion is involved.
1190
(Vincent Ladeuil, #531967)
1192
* Network transfer amounts and rates are now displayed in SI units according
1193
to the Ubuntu Units Policy <https://wiki.ubuntu.com/UnitsPolicy>.
1194
(Gordon Tyler, #514399)
1196
* Support kind markers for socket and fifo filesystem objects. This
1197
prevents ``bzr status --short`` from crashing when those files are
1198
present. (John Arbash Meinel, #303275)
1200
* ``bzr mkdir DIR`` will not create DIR unless DIR's parent is a versioned
1201
directory. (Parth Malwankar, #138600)
1203
* SSH child processes will now ignore SIGQUIT on nix systems so breaking into
1204
the debugger won't kill the session.
1205
(Martin <gzlist@googlemail.com>, #162502)
1207
* Tolerate patches with leading noise in ``bzr-handle-patch``.
1208
(Toshio Kuratomi, Martin Pool, #502076)
1210
* ``update -r`` now supports updating to revisions that are not on
1211
mainline (i.e. it supports dotted revisions).
1212
(Parth Malwankar, #517800)
1214
* Use first apparent author not committer in GNU Changelog format.
1215
(Martin von Gagern, #513322)
1220
* ``bzrlib.merge_directive._BaseMergeDirective`` has been renamed to
1221
``bzrlib.merge_directive.BaseMergeDirective`` and is now public.
1224
* ``BranchFormat.initialize`` now takes an optional ``name`` of the colocated
1225
branch to create. (Jelmer Vernooij)
1227
* ``BzrDir.get_branch_transport`` now takes an optional ``name`` of the
1228
colocated branch to open. (Jelmer Vernooij)
1230
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
1231
can set a signal handler and call ``signal.siginterrupt(signum,
1232
False)`` for it, if the platform and Python version supports it.
1233
(Andrew Bennetts, #496813)
1235
* New ``bzrlib.initialize`` is recommended for programs using bzrlib to
1236
run when starting up; it sets up several things that previously needed
1237
to be done separately.
1238
(Martin Pool, #507710)
1240
* Exporters now support a ``per_file_timestamps`` argument to write out the
1241
timestamp of the commit in which a file revision was introduced.
1244
* New method ``BzrDir.list_branches()`` that returns a sequence of branches
1245
present in a control directory. (Jelmer Vernooij)
1247
* New method ``Repository.get_known_graph_ancestry()``.
1248
(Jelmer Vernooij, #495502)
1250
* New transport methods ``readlink``, ``symlink`` and ``hardlink``.
1253
* Remove unused ``CommandFailed`` exception.
1259
* ``bzrlib.branchbuilder.BranchBuilder.build_snapshot`` now accepts a
1260
``message_callback`` in the same way that commit does. (Robert Collins)
1262
* ``bzrlib.builtins.Commit.run`` raises ``bzrlib.errors.BoundBranchOutOfDate``
1263
rather than ``bzrlib.errors.BzrCommandError`` when the bound branch is out
1264
of date. (Gary van der Merwe)
1266
* ``bzrlib.commands.run_bzr`` is more extensible: callers can supply the
1267
functions to load or disable plugins if they wish to use a different
1268
plugin mechanism; the --help, --version and no-command name code paths
1269
now use the generic pluggable command lookup infrastructure.
1272
* ``bzrlib.errors.BoundBranchOutOfDate`` has a new field ``extra_help``
1273
which can be set to add extra help to the error. (Gary van der Merwe)
1275
* New method ``Branch.automatic_tag_name`` that can be used to find the
1276
tag name for a particular revision automatically. (Jelmer Vernooij)
1278
* The methods ``BzrDir.create_branch()``, ``BzrDir.destroy_branch()`` and
1279
``BzrDir.open_branch()`` now take an optional ``name`` argument.
1285
* bzr now has a ``.testr.conf`` file in its source tree configured
1286
appropriately for running tests with Testrepository
1287
(``https://launchpad.net/testrepository``). (Robert Collins)
1289
* Documentation about testing with ``subunit`` has been tweaked.
1292
* Known failures has been added for resolve --take-other on ParentLoop
1293
conflicts. This reflects bug #537956 without fixing it.
1296
* New ``bzrlib.tests.test_import_tariff`` can make assertions about what
1297
Python modules are loaded, to guard against startup time or library
1298
dependency regressions.
1301
* PQM will now run with subunit output. To analyze a PQM error use
1302
tribunal, or cat log | subunit-filter | subunit2pyunit. (Robert Collins)
1304
* Stop sending apport crash files to ``.cache`` in the directory from
1305
which ``bzr selftest`` was run. (Martin Pool, #422350)
1307
* Tests no longer fail if "close() called during concurrent
1308
operation on the same file object" occurs when closing the log file
1309
(which can happen if a thread tries to write to the log file at the
1310
wrong moment). An warning will be written to ``stderr`` when this
1311
happens, and another warning will be written if the log file could not
1312
be closed after retrying 100 times. (Andrew Bennetts, #531746)

1318
:2.1.3: NOT RELEASED YET
1320
Compatibility Breaks
1321
********************
1329
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
1330
previously-unversioned directory within the tree: the directory is
1331
marked versioned too.
1332
(Martin Pool, #192859)
1334
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
1335
way which should help avoid problems with concurrent writers.
1336
(Vincent Ladeuil, #525571)
1338
* Don't traceback trying to unversion children files of an already
1339
unversioned directory. (Vincent Ladeuil, #494221)
1341
* Fix ``AttributeError on parent.children`` when adding a file under a
1342
directory that was a symlink in the previous commit.
1343
(Martin Pool, #192859)
1345
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
1346
which can result in "missing referenced chk root keys" errors when
1347
fetching from repositories with affected revisions.
1348
(Andrew Bennetts, #522637)
1350
* Progress bars prefer to truncate the text message rather than the
1351
counters. The spinner is shown between the network transfer indicator
1352
and the progress message. (Martin Pool)
1354
* Raise ValueError instead of a string exception.
1355
(John Arbash Meinel, #586926)
1357
* Recursive binding for checkouts is now detected by bzr. A clear error
1358
message is shown to the user. (Parth Malwankar, #405192)
1363
* Add ``bzrlib.merge.MergeIntoMerger``, which can merge part or all of a
1364
tree, and works with unrelated branches. (Andrew Bennetts)
1369
* ``bzr help patterns`` now explains case insensitive patterns and
1370
points to Python regular expression documentation.
1371
(Parth Malwankar, #594386)
1376
* Delete ``ProgressTask.note``, which was deprecated in 2.1.
1384
* Unit test added to ensure that "message" is not uses as a format variable
1385
name in BzrError subclasses as this conflicts with some Python versions.
1386
(Parth Malwankar, #603461)
1393
This release fixes two critical networking issues with older servers and
1394
with interrupted system call errors when pushing or pulling. We recommend
1395
upgrading to anyone running a 2.1.x version of bzr.
1400
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
1401
support of bzr-externals and scmproj plugins.
1402
(Alexander Belchenko, bug #572098)
1404
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
1405
(Aaron Bentley, #559436)
1407
* Do not register a SIGWINCH signal handler, instead just poll for the
1408
terminal width as needed. This avoids the "Interrupted System Call"
1409
problems that occur on POSIX with all currently released versions of
1411
(Andrew Bennetts, #583941)
1413
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
1414
versions before 1.6.
1415
(Andrew Bennetts, #528041)
1417
* Reset ``siginterrupt`` flag to False every time we handle a signal
1418
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
1419
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
1420
errors compared to registering ``signal.signal`` directly.
1423
* Reduce peak memory by one copy of compressed text.
1424
(John Arbash Meinel, #566940)
1426
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
1427
(John Arbash Meinel, #582656)
1429
* When passing a file to ``UTF8DirReader`` make sure to close the current
1430
directory file handle after the chdir fails. Otherwise when passing many
1431
filenames into a command line ``bzr status`` we would leak descriptors.
1432
(John Arbash Meinel, #583486)
1437
* ``_remember_remote_is_before`` no longer raises AssertionError when
1438
suboptimal network behaviour is noticed; instead it just mutters to the
1439
log file (and warns the user if they have set the ``hpss`` debug flag).
1440
This was causing unnecessary aborts for performance bugs that are minor
1442
(Andrew Bennetts, #528041)
1450
This is a small bugfix release. Upgrading is recommended for anyone
1451
running 2.1.0 or earlier.
1456
* Allow syscalls to automatically restart when ``TextUIFactory``'s
1457
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
1458
IO, which are often poorly handled by Python's libraries and parts of
1459
bzrlib. (Andrew Bennetts, #496813)
1461
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1462
(Martin Pool, #331095)
1464
* Fix plugin packaging on Windows. (Ian Clatworthy, #524162)
1466
* Fix stub sftp test server to call os.getcwdu().
1467
(Vincent Ladeuil, #526221, #526353)
1469
* Fixed CHM generation by moving the NEWS section template into
1470
a separate file. (Ian Clatworthy, #524184)
1472
* Merge correctly when this_tree is not a WorkingTree. (Aaron Bentley)
1474
* Register SIGWINCH handler only when creating a ``TextUIFactory``; avoids
1475
problems importing bzrlib from a non-main thread.
1476
(Elliot Murphy, #521989)
1478
* Repositories accessed via a smart server now reject being stacked on a
1479
repository in an incompatible format, as is the case when accessing them
1480
via other methods. This was causing fetches from those repositories via
1481
a smart server (e.g. using ``bzr branch``) to receive invalid data.
1482
(Andrew Bennetts, #562380)
1484
* Standardize the error handling when creating a new ``StaticTuple``
1485
(problems will raise TypeError). (Matt Nordhoff, #457979)
1487
* Warn if pyrex is too old to compile the new ``SimpleSet`` and
1488
``StaticTuple`` extensions, rather than having the build fail randomly.
1489
(John Arbash Meinel, #449776)
1494
* Added a link to the Desktop Guide. (Ian Clatworthy)
1496
* Added What's New in Bazaar 2.1 document. (Ian Clatworthy)
1498
* Drop Google Analytics from the core docs as they caused problems
1499
in the CHM files. (Ian Clatworthy, #502010)
1504
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
1505
can set a signal handler and call ``signal.siginterrupt(signum,
1506
False)`` for it, if the platform and Python version supports it.
1507
(Andrew Bennetts, #496813)
1513
:Codename: Strasbourg
1516
This release marks our second long-term-stable series. The Bazaar team
1517
has decided that we will continue to make bugfix-only 2.0.x and 2.1.x
1518
releases, along with 2.2 development releases.
1520
This is a fairly incremental update, focusing on polish and bugfixing.
1521
There are no changes for supported disk formats. Key updates include
1522
reduced memory consumption for many operations, a new per-file merge
1523
hook, ignore patterns can now include '!' to exclude files, globbing
1524
support for all commands on Windows, and support for addressing home
1525
directories via ``bzr+ssh://host/~/`` syntax.
1527
Users are encouraged to upgrade from the 2.0 stable series.
1532
* Don't require testtools to use sftp.
1533
(Vincent Ladeuil, #516183)
1535
* Fix "AttributeError in Inter1and2Helper" during fetch.
1536
(Martin Pool, #513432)
1538
* ``bzr update`` performs the two merges in a more logical order and will stop
1539
when it encounters conflicts.
1540
(Gerard Krol, #113809)
1542
* Give a better error message when doing ``bzr bind`` in an already bound
1543
branch. (Neil Martinsen-Burrell, #513063)
1545
* Ignore ``KeyError`` from ``remove_index`` during ``_abort_write_group``
1546
in a pack repository, which can happen harmlessly if the abort occurs during
1547
finishing the write group. Also use ``bzrlib.cleanup`` so that any
1548
other errors that occur while aborting the individual packs won't be
1549
hidden by secondary failures when removing the corresponding indices.
1550
(Andrew Bennetts, #423015)
1552
* Set the mtime of files exported to a directory by ``bzr export`` all to
1553
the same value to avoid confusing ``make`` and other date-based build
1554
systems. (Robert Collins, #515631)
1559
* Fetching into experimental formats will now print a warning. (Jelmer
1565
* ``Repository.deserialise_inventory`` has been renamed to
1566
``Repository._deserialise_inventory`` to indicate it is private.
1569
* ``Repository.get_inventory_xml`` has been renamed to
1570
``Repository._get_inventory_xml`` to indicate it is private.
1573
* ``Repository.serialise_inventory`` has been renamed to
1574
``Repository._serialise_inventory`` to indicate it is private.
1576
* Using the ``bzrlib.chk_map`` module from within multiple threads at the
1577
same time was broken due to race conditions with a module level page
1578
cache. This shows up as a KeyError in the ``bzrlib.lru_cache`` code with
1579
``bzrlib.chk_map`` in the backtrace, and can be triggered without using
1580
the same high level objects such as ``bzrlib.repository.Repository``
1581
from different threads. chk_map now uses a thread local cache which may
1582
increase memory pressure on processes using threads.
1583
(Robert Collins, John Arbash Meinel, #514090)
1585
* The new ``merge_file_content`` should now be ok with tests to avoid
1587
(Vincent Ladeuil, #515597)
1592
* Use ``bzrlib.cleanup`` rather than less robust ``try``/``finally``
1593
blocks in several places in ``bzrlib.merge``. This avoids masking prior
1594
errors when errors like ``ImmortalPendingDeletion`` occur during cleanup
1596
(Andrew Bennetts, #517275)
1601
* The ``remove_index`` method of
1602
``bzrlib.repofmt.pack_repo.AggregateIndex`` no longer takes a ``pack``
1603
argument. This argument was always ignored.
1604
(Andrew Bennetts, #423015)
1609
:Codename: after the bubbles
1610
:2.1.0rc2: 2010-01-29
1612
This is a quick-turn-around to update a small issue with our new per-file
1613
merge hook. We expect no major changes from this to the final 2.1.0.
1618
* The new ``merge_file_content`` hook point has been altered to provide a
1619
better API where state for extensions can be stored rather than the
1620
too-simple function based approach. This fixes a performance regression
1621
where branch configuration would be parsed per-file during merge. As
1622
part of this the included news_merger has been refactored into a base
1623
helper class ``bzrlib.merge.ConfigurableFileMerger``.
1624

:Codename: the 'new' stable
1631
:2.1.0rc1: 2009-01-21
1633
This is the first stable release candidate for Bazaar's 2.1 series. From
1634
this point onwards, the 2.1 series will be considered stable (as the 2.0
1635
series) and only bugfixes are expected to be incorporated. The dozen or so
1636
bugfixes in the 2.0.4 release are also included in this release (along
1637
with more than 15 more bugfixes). Some of the interesting features are
1638
support for per-file merge hooks, ``bzr unshelve --preview``, support
1639
for using ! in ignore files to exclude files from being ignored, a small
1640
memory leak was squashed, and many ``ObjectNotLocked`` errors were fixed.
1641
This looks to be a very good start for a new stable series.
1647
* Add bug information to log output when available.
1648
(Neil Martinsen-Burrell, Guillermo Gonzalez, #251729)
1650
* Added ``merge_file_content`` hook point to ``Merger``, allowing plugins
1651
to register custom merge logic, e.g. to provide smarter merging for
1654
* Bazaar now includes the ``news_merge`` plugin. It is disabled by
1655
default, to enable it add a ``news_merge_files`` option to your
1656
configuration. Consult ``bzr help news_merge`` for more information.
1659
* ``bzr branch`` now takes a ``--bind`` option. This lets you
1660
branch and bind all in one command. (Ian Clatworthy)
1662
* ``bzr switch`` now takes a ``--revision`` option, to allow switching to
1663
a specific revision of a branch. (Daniel Watkins, #183559)
1665
* ``bzr unshelve --preview`` can now be used to show how a patch on the
1666
shelf would be applied to the working tree.
1667
(Guilherme Salgado, #308122)
1669
* ``bzr update`` now takes a ``--revision`` argument. This lets you
1670
change the revision of the working tree to any revision in the
1671
ancestry of the current or master branch. (Matthieu Moy, Mark Hammond,
1672
Martin Pool, #45719)
1674
* ``-Dbytes`` can now be used to display the total number of bytes
1675
transferred for the current command. This information is always logged
1676
to ``.bzr.log`` for later inspection. (John Arbash Meinel)
1678
* New ignore patterns. Patterns prefixed with '!' are exceptions to
1679
ignore patterns and take precedence over regular ignores. Such
1680
exceptions are used to specify files that should be versioned which
1681
would otherwise be ignored. Patterns prefixed with '!!' act as regular
1682
ignore patterns, but have highest precedence, even over the '!'
1683
exception patterns. (John Whitley, #428031)
1685
* The ``supress_warnings`` configuration option has been introduced to disable
1686
various warnings (it currently only supports the ``format_deprecation``
1687
warning). The new option can be set in any of the following locations:
1688
``bazaar.conf``, ``locations.conf`` and/or ``branch.conf``.
1689
(Ted Gould, Matthew Fuller, Vincent Ladeuil)
1694
* Always show a message if an OS error occurs while trying to run a
1695
user-specified commit message editor.
1696
(Martin Pool, #504842)
1698
* ``bzr diff`` will now use the epoch when it is unable to determine
1699
the timestamp of a file, if the revision it was introduced in is a
1700
ghost. (Jelmer Vernooij, #295611)
1702
* ``bzr switch -b`` can now create branches that are located using directory
1703
services such as ``lp:``, even when the branch name doesn't contain a
1704
'/'. (Neil Martinsen-Burrell, #495263)
1706
* ``bzr unshelve`` has improved messages about what it is doing.
1707
(Neil Martinsen-Burrell, #496917)
1709
* Concurrent autopacking is more resilient to already-renamed pack files.
1710
If we find that a file we are about to obsolete is already obsoleted, we
1711
do not try to rename it, and we leave the file in ``obsolete_packs``.
1712
The code is also fault tolerant if a file goes missing, assuming that
1713
another process already removed the file.
1714
(John Arbash Meinel, Gareth White, #507557)
1716
* Fix "Too many concurrent requests" in reconcile when network connection
1717
fails. (Andrew Bennetts, #503878)
1719
* Fixed a side effect mutation of ``RemoteBzrDirFormat._network_name``
1720
that caused some tests to fail when run in a non-default order.
1721
Probably no user impact. (Martin Pool, #504102)
1723
* Fixed ``ObjectNotLocked`` error in ``bzr cat -rbranch:../foo FILE``.
1724
(Andrew Bennetts, #506274)
1726
* FTP transports support Unicode paths by encoding/decoding them as utf8.
1727
(Vincent Ladeuil, #472161)
1729
* Listen to the SIGWINCH signal to update the terminal width.
1730
(Vincent Ladeuil, #316357)
1732
* Progress bars are now hidden when ``--quiet`` is given.
1733
(Martin Pool, #320035)
1735
* ``SilentUIFactory`` now supports ``make_output_stream`` and discards
1736
whatever is written to it. This un-breaks some plugin tests that
1737
depended on this behaviour.
1738
(Martin Pool, #499757)
1740
* When operations update the working tree, all affected files should end
1741
up with the same mtime. (eg. when versioning a generated file, if you
1742
update the source and the generated file together, the generated file
1743
should appear up-to-date.)
1744
(John Arbash Meinel, Martin <gzlist>, #488724)
1749
* Added ``add_cleanup`` and ``cleanup_now`` to ``bzrlib.command.Command``.
1750
All the builtin commands now use ``add_cleanup`` rather than
1751
``try``/``finally`` blocks where applicable as it is simpler and more
1752
robust. (Andrew Bennetts)
1754
* All except a small number of storage formats are now hidden, making
1755
the help for numerous commands far more digestible. (Ian Clatworthy)
1757
* Attempts to open a shared repository as a branch (e.g. ``bzr branch
1758
path/to/repo``) will now include "location is a repository" as a hint in
1759
the error message. (Brian de Alwis, Andrew Bennetts, #440952)
1761
* Push will now inform the user when they are trying to push to a foreign
1762
VCS for which roundtripping is not supported, and will suggest them to
1763
use dpush. (Jelmer Vernooij)
1765
* The version of bzr being run is now written to the log file.
1766
(__monty__, #257170)
1768
* Transport network activity indicator is shown more of the time when
1769
Bazaar is doing network IO.
1775
* Add documentation on creating merges with more than one parent.
1776
(Neil Martinsen-Burrell, #481526)
1778
* Better explain the --uncommitted option of merge.
1779
(Neil Martinsen-Burrell, #505088)
1781
* Improve discussion of pending merges in the documentation for
1782
``revert``. (Neil Martinsen-Burrell, #505093)
1784
* Improved help for ``bzr send``.
1785
(Martin Pool, Bojan Nikolic)
1787
* There is a System Administrator's Guide in ``doc/en/admin-guide``,
1788
including discussions of installation, relevant plugins, security and
1789
backup. (Neil Martinsen-Burrell)
1791
* The ``conflicts`` help topic has been renamed to ``conflict-types``.
1794
* The User Reference is now presented as a series of topics.
1795
Many of the included topics have link and format tweaks applied.
1801
* Added ``cachedproperty`` decorator to ``bzrlib.decorators``.
1804
* Many test features were renamed from ``FooFeature`` to ``foo_feature``
1805
to be consistent with instances being lower case and classes being
1806
CamelCase. For the features that were more likely to be used, we added a
1807
deprecation thunk, but not all. (John Arbash Meinel)
1809
* Merger classes (such as ``Merge3Merger``) now expect a ``this_branch``
1810
parameter in their constructors, and provide ``this_branch`` as an
1811
attribute. (Andrew Bennetts)
1813
* The Branch hooks pre_change_branch_tip no longer masks exceptions raised
1814
by plugins - the original exceptions are now preserved. (Robert Collins)
1816
* The Transport ``Server.tearDown`` method is now renamed to
1817
``stop_server`` and ``setUp`` to ``start_server`` for consistency with
1818
our normal naming pattern, and to avoid confusion with Python's
1819
``TestCase.tearDown``. (Martin Pool)
1821
* ``WorkingTree.update`` implementations must now accept a ``revision``
1827
* Added ``BzrDir.open_branchV3`` smart server request, which can receive
1828
a string of details (such as "location is a repository") as part of a
1829
``nobranch`` response. (Andrew Bennetts, #440952)
1831
* New helper osutils.UnicodeOrBytesToBytesWriter which encodes unicode
1832
objects but passes str objects straight through. This is used for
1833
selftest but may be useful for diff and other operations that generate
1834
mixed output. (Robert Collins)
1836
* New exception ``NoRoundtrippingSupport``, for use by foreign branch
1837
plugins. (Jelmer Vernooij)
1842
* ``bzrlib.tests.permute_for_extension`` is a helper that simplifies
1843
running all tests in the current module, once against a pure python
1844
implementation, and once against an extension (pyrex/C) implementation.
1845
It can be used to dramatically simplify the implementation of
1846
``load_tests``. (John Arbash Meinel)
1848
* ``bzrlib.tests.TestCase`` now subclasses ``testtools.testcase.TestCase``.
1849
This permits features in testtools such as getUniqueInteger and
1850
getUniqueString to be used. Because of this, testtools version 0.9.2 or
1851
newer is now a dependency to run bzr selftest. Running with versions of
1852
testtools less than 0.9.2 will cause bzr to error while loading the test
1853
suite. (Robert Collins)
1855
* Shell-like tests now support the command "mv" for moving files. The
1856
syntax for ``mv file1 file2``, ``mv dir1 dir2`` and ``mv file dir`` is
1857
supported. (Neil Martinsen-Burrell)
1859
* The test progress bar no longer distinguishes tests that 'errored' from
1860
tests that 'failed' - they're all just failures.
1866
:2.0.6: NOT RELEASED YET
1871
* Additional merges after an unrelated branch has been merged with its
1872
history no longer crash when deleted files are involved.
1873
(Vincent Ladeuil, John Arbash Meinel, #375898)
1875
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
1876
previously-unversioned directory within the tree: the directory is
1877
marked versioned too.
1878
(Martin Pool, #192859)
1880
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
1881
target of the symlink.
1882
(Martin Pool, John Arbash Meinel, #128562)
1884
* ``bzr revert`` now only takes write lock on working tree, instead of on
1885
both working tree and branch.
1886
(Danny van Heumen, #498409)
1888
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
1889
permissions as ``.bzr`` directory on a POSIX OS.
1890
(Parth Malwankar, #262450)
1892
* Don't traceback trying to unversion children files of an already
1893
unversioned directory. (Vincent Ladeuil, #494221)
1895
* Fix ``AttributeError on parent.children`` when adding a file under a
1896
directory that was a symlink in the previous commit.
1897
(Martin Pool, #192859)
1899
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
1900
which can result in "missing referenced chk root keys" errors when
1901
fetching from repositories with affected revisions.
1902
(Andrew Bennetts, #522637)
1904
* Raise ValueError instead of a string exception.
1905
(John Arbash Meinel, #586926)
1907
* Reduce peak memory by one copy of compressed text.
1908
(John Arbash Meinel, #566940)
1910
* Repositories accessed via a smart server now reject being stacked on a
1911
repository in an incompatible format, as is the case when accessing them
1912
via other methods. This was causing fetches from those repositories via
1913
a smart server (e.g. using ``bzr branch``) to receive invalid data.
1914
(Andrew Bennetts, #562380)
1916
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
1917
error. This error was caused by 2.0 not being updated when upstream
1918
python merged the end of run patch, which chose ``stopTestRun`` rather than
1919
``done``. (Robert Collins, #571437)
1921
* When passing a file to ``UTF8DirReader`` make sure to close the current
1922
directory file handle after the chdir fails. Otherwise when passing many
1923
filenames into a command line ``bzr status`` we would leak descriptors.
1924
(John Arbash Meinel, #583486)
1930
* ``build_tree_contents`` can create symlinks.
1931
(Martin Pool, John Arbash Meinel)
1939
This fifth release in our 2.0 series addresses several user-inconvenience
1940
bugs. None are critical, but upgrading is recommended for all users on
1941
earlier 2.0 releases.
1946
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1947
(Martin Pool, #331095)
1949
* Concurrent autopacking is more resilient to already-renamed pack files.
1950
If we find that a file we are about to obsolete is already obsoleted, we
1951
do not try to rename it, and we leave the file in ``obsolete_packs``.
1952
The code is also fault tolerant if a file goes missing, assuming that
1953
another process already removed the file.
1954
(John Arbash Meinel, Gareth White, #507557)
1956
* Cope with the lockdir ``held/info`` file being empty, which seems to
1957
happen fairly often if the process is suddenly interrupted while taking
1959
(Martin Pool, #185103)
1961
* Give the warning about potentially slow cross-format fetches much
1962
earlier on in the fetch operation. Don't show this message during
1963
upgrades, and show the correct format indication for remote
1965
(Martin Pool, #456077, #515356, #513157)
1967
* Handle renames correctly when there are files or directories that
1968
differ only in case. (Chris Jones, Martin Pool, #368931)
1970
* If ``bzr push --create-prefix`` triggers an unexpected ``NoSuchFile``
1971
error, report that error rather than failing with an unhelpful
1972
``UnboundLocalError``.
1973
(Andrew Bennetts, #423563)
1975
* Running ``bzr`` command without any arguments now shows bzr
1976
version number along with rest of the help text.
1977
(Parth Malwankar, #369501)
1979
* Use osutils.O_NOINHERIT for some files on win32 to avoid PermissionDenied
1981
(Inada Naoki, #524560)
1986
* Added ``location-alias`` help topic.
1987
(Andrew Bennetts, #337834)
1989
* Fixed CHM generation by moving the NEWS section template into
1990
a separate file. (Ian Clatworthy, #524184)
1996
:Codename: smooth sailing
1999
The fourth bugfix-only release in the 2.0 series contains more than a
2000
dozen bugfixes relative to 2.0.3. The primary focus is on handling
2001
interruptions and concurrent operations more cleanly, there is also a fair
2002
improvement to ``bzr export`` when exporting a remote branch.
2008
* ``bzr annotate`` on another branch with ``-r branch:...`` no longer
2009
fails with an ``ObjectNotLocked`` error. (Andrew Bennetts, #496590)
2011
* ``bzr export dir`` now requests all file content as a record stream,
2012
rather than requsting the file content one file-at-a-time. This can make
2013
exporting over the network significantly faster (54min => 9min in one
2014
case). (John Arbash Meinel, #343218)
2016
* ``bzr serve`` no longer slowly leaks memory. The compiled
2017
``bzrlib.bencode.Encoder()`` class was using ``__del__`` to cleanup and
2018
free resources, and it should have been using ``__dealloc__``.
2019
This will likely have an impact on any other process that is serving for
2020
an extended period of time. (John Arbash Meinel, #494406)
2022
* Check for SIGINT (Ctrl-C) and other signals immediately if ``readdir``
2023
returns ``EINTR`` by calling ``PyErr_CheckSignals``. This affected the
2024
optional ``_readdir_pyx`` extension. (Andrew Bennetts, #495023)
2026
* Concurrent autopacks will no longer lose a newly created pack file.
2027
There was a race condition, where if the reload happened at the right
2028
time, the second packer would forget the name of the newly added pack
2029
file. (John Arbash Meinel, Gareth White, #507566)
2031
* Give a clearer message if the lockdir disappears after being apparently
2032
successfully taken. (Martin Pool, #498378)
2034
* Give a warning when fetching between repositories (local or remote) with
2035
sufficiently different formats that the content will need to be
2036
serialized (ie ``InterDifferingSerializer`` or ``inventory-deltas``), so
2037
the user has a clue that upgrading could make it faster.
2038
(Martin Pool, #456077)
2040
* If we fail to open ``~/.bzr.log`` write a clear message to stderr rather
2041
than using ``warning()``. The log file is opened before logging is set
2042
up, and it leads to very confusing: 'no handlers for "bzr"' messages for
2043
users, rather than something nicer.
2044
(John Arbash Meinel, Barry Warsaw, #503886)
2046
* Refuse to build with any Pyrex 0.9.4 release, as they have known bugs.
2047
(Martin Pool, John Arbash Meinel, #449372)
2049
* ``setup.py bdist_rpm`` now properly finds extra files needed for the
2050
build. (there is still the distutils bug
2051
http://bugs.python.org/issue644744) (Joe Julian, #175839)
2053
* The 2a format wasn't properly restarting autopacks when something
2054
changed underneath it (like another autopack). Now concurrent
2055
autopackers will properly succeed. (John Arbash Meinel, #495000)
2057
* ``TreeTransform`` can now handle when a delta says that the file id for
2058
the tree root changes. Rather than trying to rename your working
2059
directory, or failing early saying that you can't have multiple
2060
tree roots. This also fixes revert, update, and pull when the root id
2061
changes. (John Arbash Meinel, #494269, #504390)
2063
* ``_update_current_block`` no longer suppresses exceptions, so ^C at just
2064
the right time will get propagated, rather than silently failing to move
2065
the block pointer. (John Arbash Meinel, Gareth White, #495023)
2070
* We have a new ``test_source`` that ensures all pyrex ``cdef`` functions
2071
handle exceptions somehow. (Possibly by setting ``# cannot_raise``
2072
rather than an ``except ?:`` clause.) This should help prevent bugs like
2073
bug #495023. (John Arbash Meinel)

:2.1.0b4: 2009-12-14
2082
The fourth beta release in the 2.1 series brings with it a significant
2083
number of bugfixes (~20). The test suite is once again (finally) "green"
2084
on Windows, and should remain that way for future releases. There are a
2085
few performance related updates (faster upgrade and log), and several UI
2086
tweaks. There has also been a significant number of tweaks to the runtime
2087
documentation. 2.1.0b4 include everything from the 2.0.3 release.
2090
Compatibility Breaks
2091
********************
2093
* The BZR_SSH environmental variable may now be set to the path of a secure
2094
shell client. If currently set to the value ``ssh`` it will now guess the
2095
vendor of the program with that name, to restore the old behaviour that
2096
indicated the SSH Corporation client use ``sshcorp`` instead as the magic
2097
string. (Martin <gzlist@googlemail.com>, #176292)
2102
* ``bzr commit`` now has a ``--commit-time`` option.
2103
(Alexander Sack, #459276)
2105
* ``-Dhpss`` now increases logging done when run on the bzr server,
2106
similarly to how it works on the client. (John Arbash Meinel)
2108
* New option ``bzr unshelve --keep`` applies the changes and leaves them
2109
on the shelf. (Martin Pool, Oscar Fuentes, #492091)
2111
* The ``BZR_COLUMNS`` envrionment variable can be set to force bzr to
2112
respect a given terminal width. This can be useful when output is
2113
redirected or in obscure cases where the default value is not
2114
appropriate. Pagers can use it to get a better control of the line
2118
* The new command ``bzr lp-mirror`` will request that Launchpad update its
2119
mirror of a local branch. This command will only function if launchpadlib
2127
* After renaming a file, the dirstate could accidentally reference
2128
``source\\path`` rather than ``source/path`` on Windows. This might be a
2129
source of some dirstate-related failures. (John Arbash Meinel)
2131
* ``bzr commit`` now detects commit messages that looks like file names
2132
and issues a warning.
2133
(Gioele Barabucci, #73073)
2135
* ``bzr ignore /`` no longer causes an IndexError. (Gorden Tyler, #456036)
2137
* ``bzr log -n0 -rN`` should not return revisions beyond its merged revisions.
2138
(#325618, #484109, Marius Kruger)
2140
* ``bzr merge --weave`` and ``--lca`` will now create ``.BASE`` files for
2141
files with conflicts (similar to ``--merge3``). The contents of the file
2142
is a synthesis of all bases used for the merge.
2143
(John Arbash Meinel, #40412)
2145
* ``bzr mv --quiet`` really is quiet now. (Gordon Tyler, #271790)
2147
* ``bzr serve`` is more clear about the risk of supplying --allow-writes.
2148
(Robert Collins, #84659)
2150
* ``bzr serve --quiet`` really is quiet now. (Gordon Tyler, #252834)
2152
* Fix bug with redirected URLs over authenticated HTTP.
2153
(Glen Mailer, Neil Martinsen-Burrell, Vincent Ladeuil, #395714)
2155
* Interactive merge doesn't leave branch locks behind. (Aaron Bentley)
2157
* Lots of bugfixes for the test suite on Windows. We should once again
2158
have a test suite with no failures on Windows. (John Arbash Meinel)
2160
* ``osutils.terminal_width()`` obeys the BZR_COLUMNS environment
2161
variable but returns None if the terminal is not a tty (when output is
2162
redirected for example). Also fixes its usage under OSes that doesn't
2163
provide termios.TIOCGWINSZ. Make sure the corresponding tests runs on
2165
(Joke de Buhr, Vincent Ladeuil, #353370, #62539)
2166
(John Arbash Meinel, Vincent Ladeuil, #492561)
2168
* Terminate ssh subprocesses when no references to them remain, fixing
2169
subprocess and file descriptor leaks. (Andrew Bennetts, #426662)
2171
* The ``--hardlink`` option of ``bzr branch`` and ``bzr checkout`` now
2172
works for 2a format trees. Only files unaffected by content filters
2173
will be hardlinked. (Andrew Bennetts, #408193)
2175
* The new glob expansion on Windows would replace all ``\`` characters
2176
with ``/`` even if it there wasn't a glob to expand, the arg was quoted,
2177
etc. Now only change slashes if there is something being glob expanded.
2178
(John Arbash Meinel, #485771)
2180
* Use our faster ``KnownGraph.heads()`` functionality when computing the
2181
new rich-root heads. This can cut a conversion time in half (mysql from
2182
13.5h => 6.2h) (John Arbash Meinel, #487632)
2184
* When launching a external diff tool via bzr diff --using, temporary files
2185
are no longer created, rather, the path to the file in the working tree is
2186
passed to the external diff tool. This allows the file to be edited if the
2187
diff tool provides for this. (Gary van der Merwe, #490738)
2189
* The launchpad-open command can now be used from a subdirectory of a
2190
branch, not just from the root of the branch.
2191
(Neil Martinsen-Burrell, #489102)
2197
* ``bzr log`` is now faster. (Ian Clatworthy)
2199
* ``bzr update`` provides feedback on which branch it is up to date with.
2200
(Neil Martinsen-Burrell)
2202
* ``bzr upgrade`` from pre-2a to 2a can be significantly faster (4x).
2203
For details see the xml8 patch and heads() improvements.
2204
(John Arbash Meinel)
2206
* ``bzrlib.urlutils.local_path_from_url`` now accepts
2207
'file://localhost/' as well as 'file:///' URLs on POSIX. (Michael
2210
* The progress bar now shows only a spinner and per-operation counts,
2211
not an overall progress bar. The previous bar was often not correlated
2212
with real overall operation progress, either because the operations take
2213
nonlinear time, or because at the start of the operation Bazaar couldn't
2214
estimate how much work there was to do. (Martin Pool)
2219
* Lots of documentation tweaks for inline help topics and command help
2225
* ``bzrlib.textui`` (vestigial module) removed. (Martin Pool)
2227
* The Launchpad plugin now has a function ``login`` which will log in to
2228
Launchpad with launchpadlib, and ``load_branch`` which will return the
2229
Launchpad Branch object corresponding to a given Bazaar Branch object.
2235
* New test Feature: ``ModuleAvailableFeature``. It is designed to make it
2236
easier to handle what tests you want to run based on what modules can be
2237
imported. (Rather than lots of custom-implemented features that were
2238
basically copy-and-pasted.) (John Arbash Meinel)
2240
* ``osutils.timer_func()`` can be used to get either ``time.time()`` or
2241
``time.clock()`` when you want to do performance timing.
2242
``time.time()`` is limited to 15ms resolution on Windows, but
2243
``time.clock()`` gives CPU and not wall-clock time on other platforms.
2244
(John Arbash Meinel)
2246
* Several code paths that were calling ``Transport.get().read()`` have
2247
been changed to the equalivent ``Transport.get_bytes()``. The main
2248
difference is that the latter will explicitly call ``file.close()``,
2249
rather than expecting the garbage collector to handle it. This helps
2250
with some race conditions on Windows during the test suite and sftp
2251
tests. (John Arbash Meinel)
2256
* TestCaseWithMemoryTransport no longer sets $HOME and $BZR_HOME to
2257
unicode strings. (Michael Hudson, #464174)
2263
:Codename: little italy
2267
The third stable release of Bazaar has a small handful of bugfixes. As
2268
expected, this has no internal or external compatibility changes versus
2274
* ``bzr push --use-existing-dir`` no longer crashes if the directory
2275
exists but contains an invalid ``.bzr`` directory.
2276
(Andrew Bennetts, #423563)
2278
* Content filters are now applied correctly after pull, merge and switch.
2279
(Ian Clatworthy, #385879)
2281
* Fix a potential segfault in the groupcompress hash map handling code.
2282
When inserting new entries, if the final hash bucket was empty, we could
2283
end up trying to access if ``(last_entry+1)->ptr == NULL``.
2284
(John Arbash Meinel, #490228)
2286
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
2292
:Codename: after sprint recovery
2293
:2.1.0b3: 2009-11-16
2295
This release was pushed up from its normal release cycle due to a
2296
regression in python 2.4 compatibility in 2.1.0b2. Since this regression
2297
was caught before 2.1.0b2 was officially announced, the full changelog
2298
includes both 2.1.0b3 and 2.1.0b2 changes.
2300
Highlights of 2.1.0b3 are: new globbing code for all commands on Windows,
2301
the test suite now conforms to python's trunk enhanced semantics (skip,
2302
etc.), and ``bzr info -v`` will now report the correct branch and repo
2303
formats for Remote objects.
2309
* Users can define a shelve editor to provide shelf functionality at a
2310
granularity finer than per-patch-hunk. (Aaron Bentley)
2315
* Fix for shell completion and short options. (Benoît PIERRE)
2317
* Fix ``bzr --profile-imports`` with Python 2.6. (Martin Pool)
2319
* Hooks daughter classes should always call the base constructor.
2320
(Alexander Belchenko, Vincent Ladeuil, #389648)
2322
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
2324
* On Windows, do glob expansion at the command-line level (as is usually
2325
done in bash, etc.) This means that *all* commands get glob expansion
2326
(bzr status, bzr add, bzr mv, etc). It uses a custom command line
2327
parser, which allows us to know if a given section was quoted. It means
2328
you can now do ``bzr ignore "*.py"``.
2329
(John Arbash Meinel, #425510, #426410, #194450)
2331
* Sanitize commit messages that come in from the '-m' flag. We translate
2332
'\r\n' => '\n' and a plain '\r' => '\n'. The storage layer doesn't
2333
allow those because XML store silently translate it anyway. (The parser
2334
auto-translates \r\n => \n in ways that are hard for us to catch.)
2336
* Show correct branch and repository format descriptions in
2337
``bzr info -v`` on a smart server location. (Andrew Bennetts, #196080)
2339
* The fix for bug #186920 accidentally broke compatibility with python
2340
2.4. (Vincent Ladeuil, #475585)
2342
* Using ``Repository.get_commit_builder().record_iter_changes()`` now
2343
correctly sets ``self.inv_sha1`` to a sha1 string and
2344
``self.new_inventory`` to an Inventory instance after calling
2345
``self.finish_inventory()``. (Previously it accidently set both values
2346
as a tuple on ``self.inv_sha1``. This was missed because
2347
``repo.add_revision`` ignores the supplied inventory sha1 and recomputes
2348
the sha1 from the repo directly. (John Arbash Meinel)
2350
* Shelve command refuse to run if there is no real terminal.
2351
(Alexander Belchenko)
2353
* Avoid unnecessarily flushing of trace file; it's now unbuffered at the
2354
Python level. (Martin Pool)
2359
* Include Japanese translations for documentation (Inada Naoki)
2361
* New API ``ui_factory.make_output_stream`` to be used for sending bulk
2362
(rather than user-interaction) data to stdout. This automatically
2363
coordinates with progress bars or other terminal activity, and can be
2365
(Martin Pool, 493944)
2370
* Some of the core groupcompress functionality now releases the GIL before
2371
operation. Similar to how zlib and bz2 operate without the GIL in the
2372
core compression and decompression routines. (John Arbash Meinel)
2377
* -Dhpssvfs will now trigger on ``RemoteBzrDir._ensure_real``, providing
2378
more debugging of VFS access triggers. (Robert Collins)
2380
* KnownFailure is now signalled to ``ExtendedTestResult`` using the same
2381
method that Python 2.7 uses - ``addExpectedFailure``. (Robert Collins)
2383
* ``--parallel=fork`` is now compatible with --subunit.
2384
(Robert Collins, Vincent Ladeuil, #419776)
2386
* Reporting of failures shows test ids not descriptions and thus shows
2387
parameterised tests correctly. (Robert Collins)
2389
* TestNotApplicable is now handled within the TestCase.run method rather
2390
than being looked for within ``ExtendedTestResult.addError``. This
2391
provides better handling with other ``TestResult`` objects, degrading to
2392
sucess rather than error. (Robert Collins)
2394
* The private method ``_testConcluded`` on ``ExtendedTestResult`` has been
2395
removed - it was empty and unused. (Robert Collins)
2397
* UnavailableFeature is now handled within the TestCase.run method rather
2398
than being looked for within addError. If the Result object does not
2399
have an addNotSupported method, addSkip is attempted instead, and
2400
failing that addSuccess. (Robert Collins)
2402
* When a TestResult does not have an addSkip method, skipped tests are now
2403
reported as successful tests, rather than as errors. This change is
2404
to make it possible to get a clean test run with a less capable
2405
TestResult. (Robert Collins)
2412
:Codename: a load off my mind
2413
:2.1.0b2: 2009-11-02
2415
This is our second feature-filled release since 2.0, pushing us down the
2416
path to a 2.1.0. Once again, all bugfixes in 2.0.2 are present in 2.1.0b2.
2418
Key highlights in this release are: improved handling of
2419
failures-during-cleanup for commit, fixing a long-standing bug with
2420
``bzr+http`` and shared repositories, all ``lp:`` urls to be resolved
2421
behind proxies, and a new StaticTuple datatype, allowing us to reduce
2422
memory consumption (50%) and garbage collector overhead (40% faster) for
2425
* A new ``--concurrency`` option has been added as well as an associated
2426
BZR_CONCURRENCY environment variable to specify the number of
2427
processes that can be run concurrently when running ``bzr selftest``. The
2428
command-line option overrides the environment variable if both are
2429
specified. If none is specified. the number of processes is obtained
2430
from the OS as before. (Matt Nordhoff, Vincent Ladeuil)
2435
* ``bzr+http`` servers no longer give spurious jail break errors when
2436
serving branches inside a shared repository. (Andrew Bennetts, #348308)
2438
* Errors during commit are handled more robustly so that knock-on errors
2439
are less likely to occur, and will not obscure the original error if
2440
they do occur. This fixes some causes of ``TooManyConcurrentRequests``
2441
and similar errors. (Andrew Bennetts, #429747, #243391)
2443
* Launchpad urls can now be resolved from behind proxies.
2444
(Gordon Tyler, Vincent Ladeuil, #186920)
2446
* Reduce the strictness for StaticTuple, instead add a debug flag
2447
``-Dstatic_tuple`` which will change apis to be strict and raise errors.
2448
This way, most users won't see failures, but developers can improve
2449
internals. (John Arbash Meinel, #471193)
2451
* TreeTransform.adjust_path updates the limbo paths of descendants of adjusted
2452
files. (Aaron Bentley)
2454
* Unicode paths are now handled correctly and consistently by the smart
2455
server. (Andrew Bennetts, Michael Hudson, #458762)
2460
* When reading index files, we now use a ``StaticTuple`` rather than a
2461
plain ``tuple`` object. This generally gives a 20% decrease in peak
2462
memory, and can give a performance boost up to 40% on large projects.
2463
(John Arbash Meinel)
2465
* Peak memory under certain operations has been reduced significantly.
2466
(eg, 'bzr branch launchpad standalone' is cut in half)
2467
(John Arbash Meinel)
2472
* Filtered views user documentation upgraded to refer to format 2a
2473
instead of pre-2.0 formats. (Ian Clatworthy)
2478
* Remove deprecated ``CLIUIFactory``. (Martin Pool)
2480
* ``UIFactory`` now has new ``show_error``, ``show_message`` and
2481
``show_warning`` methods, which can be hooked by non-text UIs.
2487
* Added ``bzrlib._simple_set_pyx``. This is a hybrid between a Set and a
2488
Dict (it only holds keys, but you can lookup the object located at a
2489
given key). It has significantly reduced memory consumption versus the
2490
builtin objects (1/2 the size of Set, 1/3rd the size of Dict). This is
2491
used as the interning structure for StaticTuple objects.
2492
(John Arbash Meinel)
2494
* ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
2495
the btree index parser and the chk map parser. This class functions
2496
similarly to ``tuple`` objects. However, it can only point to a limited
2497
collection of types. (Currently StaticTuple, str, unicode, None, bool,
2498
int, long, float, but not subclasses). This allows us to remove it from
2499
the garbage collector (it cannot be in a cycle), it also allows us to
2500
intern the objects. In testing, this can reduce peak memory by 20-40%,
2501
and significantly improve performance by removing objects from being
2502
inspected by the garbage collector. (John Arbash Meinel)
2504
* ``GroupCompressBlock._ensure_content()`` will now release the
2505
``zlib.decompressobj()`` when the first request is for all of the
2506
content. (Previously it would only be released if you made a request for
2507
part of the content, and then all of it later.) This turns out to be a
2508
significant memory savings, as a ``zstream`` carries around approx 260kB
2509
of internal state and buffers. (For branching bzr.dev this drops peak
2510
memory from 382MB => 345MB.) (John Arbash Meinel)
2512
* When streaming content between ``2a`` format repositories, we now clear
2513
caches from earlier versioned files. (So 'revisions' is cleared when we
2514
start reading 'inventories', etc.) This can have a significant impact on
2515
peak memory for initial copies (~200MB). (John Arbash Meinel)
2521
:Codename: after the scare
2524
The second in our "let's keep the stable bugfixes flowing" series. As
2525
expected this has a few (~9) bugfixes relative to 2.0.1, and no major api
2526
changes or features.
2531
* Avoid "NoneType has no attribute st_mode" error when files disappear
2532
from a directory while it's being read. (Martin Pool, #446033)
2534
* Content filters are now applied correctly after revert.
2537
* Diff parsing handles "Binary files differ" hunks. (Aaron Bentley, #436325)
2539
* Fetching from stacked pre-2a repository via a smart server no longer
2540
fails intermittently with "second push failed to complete".
2541
(Andrew Bennetts, #437626)
2543
* Fix typos left after test_selftest refactoring.
2544
(Vincent Ladeuil, Matt Nordhoff, #461149)
2546
* Fixed ``ObjectNotLocked`` errors during ``bzr log -r NNN somefile``.
2547
(Andrew Bennetts, #445171)
2549
* PreviewTree file names are not limited by the encoding of the temp
2550
directory's filesystem. (Aaron Bentley, #436794)
2555
* ``bzr log`` now read-locks branches exactly once, so makes better use of
2556
data caches. (Andrew Bennetts)
2561
* Filtered views user documentation upgraded to refer to format 2a
2562
instead of pre-2.0 formats. (Ian Clatworthy)
2568
:Codename: While the cat is away
2569
:2.1.0b1: 2009-10-14
2571
This is the first development release in the new split "stable" and
2572
"development" series. As such, the release is a snapshot of bzr.dev
2573
without creating a release candidate first. This release includes a
2574
fair amount of internal changes, with deprecated code being removed,
2575
and several new feature developments. People looking for a stable code
2576
base with only bugfixes should focus on the 2.0.1 release. All bugfixes
2577
present in 2.0.1 are present in 2.1.0b1.
2579
Highlights include support for ``bzr+ssh://host/~/homedir`` style urls,
2580
finer control over the plugin search path via extended BZR_PLUGIN_PATH
2581
syntax, visible warnings when extension modules fail to load, and improved
2582
error handling during unlocking.
2588
* Bazaar can now send mail through Apple OS X Mail.app.
2591
* ``bzr+ssh`` and ``bzr`` paths can now be relative to home directories
2592
specified in the URL. Paths starting with a path segment of ``~`` are
2593
relative to the home directory of the user running the server, and paths
2594
starting with ``~user`` are relative to the home directory of the named
2595
user. For example, for a user "bob" with a home directory of
2596
``/home/bob``, these URLs are all equivalent:
2598
* ``bzr+ssh://bob@host/~/repo``
2599
* ``bzr+ssh://bob@host/~bob/repo``
2600
* ``bzr+ssh://bob@host/home/bob/repo``
2602
If ``bzr serve`` was invoked with a ``--directory`` argument, then no
2603
home directories outside that directory will be accessible via this
2606
This is a feature of ``bzr serve``, so pre-2.1 clients will
2607
automatically benefit from this feature when ``bzr`` on the server is
2608
upgraded. (Andrew Bennetts, #109143)
2610
* Extensions can now be compiled if either Cython or Pyrex is available.
2611
Currently Pyrex is preferred, but that may change in the future.
2614
* Give more control on BZR_PLUGIN_PATH by providing a way to refer to or
2615
disable the user, site and core plugin directories.
2616
(Vincent Ladeuil, #412930, #316192, #145612)
2621
* Bazaar's native protocol code now correctly handles EINTR, which most
2622
noticeably occurs if you break in to the debugger while connected to a
2623
bzr+ssh server. You can now can continue from the debugger (by typing
2624
'c') and the process continues. However, note that pressing C-\ in the
2625
shell may still kill the SSH process, which is bug 162509, so you must
2626
sent a signal to the bzr process specifically, for example by typing
2627
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
2629
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
2630
filename will issue a warning and skip over those files.
2631
(Robert Collins, #3918)
2633
* ``bzr dpush`` now aborts if uncommitted changes (including pending merges)
2634
are present in the working tree. The configuration option ``dpush_strict``
2635
can be used to set the default for this behavior.
2636
(Vincent Ladeuil, #438158)
2638
* ``bzr merge`` and ``bzr remove-tree`` now requires --force if pending
2639
merges are present in the working tree.
2640
(Vincent Ladeuil, #426344)
2642
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
2643
traceback. (Martin Pool, #109115)
2645
* Don't give a warning on Windows when failing to import ``_readdir_pyx``
2646
as it is never built. (John Arbash Meinel, #430645)
2648
* Don't restrict the command name used to run the test suite.
2649
(Vincent Ladeuil, #419950)
2651
* ftp transports were built differently when the kerberos python module was
2652
present leading to obscure failures related to ASCII/BINARY modes.
2653
(Vincent Ladeuil, #443041)
2655
* Network streams now decode adjacent records of the same type into a
2656
single stream, reducing layering churn. (Robert Collins)
2658
* PreviewTree behaves correctly when get_file_mtime is invoked on an unmodified
2659
file. (Aaron Bentley, #251532)
2661
* Registry objects should not use iteritems() when asked to use items().
2662
(Vincent Ladeuil, #430510)
2664
* Weave based repositories couldn't be cloned when committers were using
2665
domains or user ids embedding '.sig'. Now they can.
2666
(Matthew Fuller, Vincent Ladeuil, #430868)
2671
* Revision specifiers can now be given in a more DWIM form, without
2672
needing explicit prefixes for specifiers like tags or revision id's.
2673
See ``bzr help revisionspec`` for full details. (Matthew Fuller)
2675
* Bazaar gives a warning before exiting, and writes into ``.bzr.log``, if
2676
compiled extensions can't be loaded. This typically indicates a
2677
packaging or installation problem. In this case Bazaar will keep
2678
running using pure-Python versions, but this may be substantially
2679
slower. The warning can be disabled by setting
2680
``ignore_missing_extensions = True`` in ``bazaar.conf``.
2681
See also <https://answers.launchpad.net/bzr/+faq/703>.
2682
(Martin Pool, #406113, #430529)
2684
* Secondary errors that occur during Branch.unlock and Repository.unlock
2685
no longer obscure the original error. These methods now use a new
2686
decorator, ``only_raises``. This fixes many causes of
2687
``TooManyConcurrentRequests`` and similar errors.
2688
(Andrew Bennetts, #429747)
2693
* Describe the new shell-like test feature. (Vincent Ladeuil)
2695
* Help on hooks no longer says 'Not deprecated' for hooks that are
2696
currently supported. (Ian Clatworthy, #422415)
2701
* ``bzrlib.user_encoding`` has been removed; use
2702
``bzrlib.osutils.get_user_encoding`` instead. (Martin Pool)
2704
* ``bzrlib.tests`` now uses ``stopTestRun`` for its ``TestResult``
2705
subclasses - the same as python's unittest module. (Robert Collins)
2707
* ``diff._get_trees_to_diff`` has been renamed to
2708
``diff.get_trees_and_branches_to_diff``. It is now a public API, and it
2709
returns the old and new branches. (Gary van der Merwe)
2711
* ``bzrlib.trace.log_error``, ``error`` and ``info`` have been deprecated.
2714
* ``MutableTree.has_changes()`` does not require a tree parameter anymore. It
2715
now defaults to comparing to the basis tree. It now checks for pending
2716
merges too. ``Merger.check_basis`` has been deprecated and replaced by the
2717
corresponding has_changes() calls. ``Merge.compare_basis``,
2718
``Merger.file_revisions`` and ``Merger.ensure_revision_trees`` have also
2720
(Vincent Ladeuil, #440631)
2722
* ``ProgressTask.note`` is deprecated.
2728
* Added ``-Drelock`` debug flag. It will ``note`` a message every time a
2729
repository or branch object is unlocked then relocked the same way.
2732
* ``BTreeLeafParser.extract_key`` has been tweaked slightly to reduce
2733
mallocs while parsing the index (approx 3=>1 mallocs per key read).
2734
This results in a 10% speedup while reading an index.
2735
(John Arbash Meinel)
2737
* The ``bzrlib.lsprof`` module has a new class ``BzrProfiler`` which makes
2738
profiling in some situations like callbacks and generators easier.
2744
* Passing ``--lsprof-tests -v`` to bzr selftest will cause lsprof output to
2745
be output for every test. Note that this is very verbose! (Robert Collins)
2747
* Setting ``BZR_TEST_PDB=1`` when running selftest will cause a pdb
2748
post_mortem to be triggered when a test failure occurs. (Robert Collins)
2750
* Shell-like tests can now be written. Code in ``bzrlib/tests/script.py`` ,
2751
documentation in ``developers/testing.txt`` for details.
2754
* Some tests could end up with the same id, that was dormant for
2756
(Vincent Ladeuil, #442980)
2758
* Stop showing the number of tests due to missing features in the test
2759
progress bar. (Martin Pool)
2761
* Test parameterisation now does a shallow copy, not a deep copy of the test
2762
to be parameterised. This is not expected to break external use of test
2763
parameterisation, and is substantially faster. (Robert Collins)
2765
* Tests that try to open a bzr dir on an arbitrary transport will now
2766
fail unless they have explicitly permitted the transport via
2767
``self.permit_url``. The standard test factories such as ``self.get_url``
2768
will permit the urls they provide automatically, so only exceptional
2769
tests should need to do this. (Robert Collins)
2771
* The break-in test no longer cares about clean shutdown of the child,
2772
instead it is happy if the debugger starts up. (Robert Collins)
2774
* The full test suite is expected to pass when the C extensions are not
2775
present. (Vincent Ladeuil, #430749)
2781
:Codename: Stability First
2784
The first of our new ongoing bugfix-only stable releases has arrived. It
2785
includes a collection of 12 bugfixes applied to bzr 2.0.0, but does not
2786
include any of the feature development in the 2.1.0 series.
2792
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
2793
filename will issue a warning and skip over those files.
2794
(Robert Collins, #3918)
2796
* bzr will attempt to authenticate with SSH servers that support
2797
``keyboard-interactive`` auth but not ``password`` auth when using
2798
Paramiko. (Andrew Bennetts, #433846)
2800
* Fixed fetches from a stacked branch on a smart server that were failing
2801
with some combinations of remote and local formats. This was causing
2802
"unknown object type identifier 60" errors. (Andrew Bennetts, #427736)
2804
* Fixed ``ObjectNotLocked`` errors when doing some log and diff operations
2805
on branches via a smart server. (Andrew Bennetts, #389413)
2807
* Handle things like ``bzr add foo`` and ``bzr rm foo`` when the tree is
2808
at the root of a drive. ``osutils._cicp_canonical_relpath`` always
2809
assumed that ``abspath()`` returned a path that did not have a trailing
2810
``/``, but that is not true when working at the root of the filesystem.
2811
(John Arbash Meinel, Jason Spashett, #322807)
2813
* Hide deprecation warnings for 'final' releases for python2.6.
2814
(John Arbash Meinel, #440062)
2816
* Improve the time for ``bzr log DIR`` for 2a format repositories.
2817
We had been using the same code path as for <2a formats, which required
2818
iterating over all objects in all revisions.
2819
(John Arbash Meinel, #374730)
2821
* Make sure that we unlock the tree if we fail to create a TreeTransform
2822
object when doing a merge, and there is limbo, or pending-deletions
2823
directory. (Gary van der Merwe, #427773)
2825
* Occasional IndexError on renamed files have been fixed. Operations that
2826
set a full inventory in the working tree will now go via the
2827
apply_inventory_delta code path which is simpler and easier to
2828
understand than dirstates set_state_from_inventory method. This may
2829
have a small performance impact on operations built on _write_inventory,
2830
but such operations are already doing full tree scans, so no radical
2831
performance change should be observed. (Robert Collins, #403322)
2833
* Retrieving file text or mtime from a _PreviewTree has good performance when
2834
there are many changes. (Aaron Bentley)
2836
* The CHK index pages now use an unlimited cache size. With a limited
2837
cache and a large project, the random access of chk pages could cause us
2838
to download the entire cix file many times.
2839
(John Arbash Meinel, #402623)
2841
* When a file kind becomes unversionable after being added, a sensible
2842
error will be shown instead of a traceback. (Robert Collins, #438569)
2847
* Improved README. (Ian Clatworthy)
2849
* Improved upgrade documentation for Launchpad branches.
2857
:Codename: Instant Karma
2859
This release of Bazaar makes the 2a (previously 'brisbane-core') format
2860
the default when new branches or repositories are created. This format is
2861
substantially smaller and faster for many operations. Most of the work in
2862
this release focuses on bug fixes and stabilization, covering both 2a and
2863
previous formats. (See the Upgrade Guide for information on migrating
2866
This release also improves the documentation content and presentation,
2867
including adding Windows HtmlHelp manuals.
2869
The Bazaar team decided that 2.0 will be a long-term supported release,
2870
with bugfix-only 2.0.x releases based on it, continuing for at least six
2871
months or until the following stable release.
2873
Changes from 2.0.0rc2 to final
2874
******************************
2876
* Officially branded as 2.0.0 rather than 2.0 to clarify between things
2877
that "want to happen on the 2.0.x stable series" versus things that want
2878
to "land in 2.0.0". (Changes how bzrlib._format_version_tuple() handles
2879
micro = 0.) (John Arbash Meinel)
2885
:2.0.0rc2: 2009-09-10
2890
* Added post_commit hook for mutable trees. This allows the keywords
2891
plugin to expand keywords on files changed by the commit.
2892
(Ian Clatworthy, #408841)
2897
* Bazaar's native protocol code now correctly handles EINTR, which most
2898
noticeably occurs if you break in to the debugger while connected to a
2899
bzr+ssh server. You can now can continue from the debugger (by typing
2900
'c') and the process continues. However, note that pressing C-\ in the
2901
shell may still kill the SSH process, which is bug 162509, so you must
2902
sent a signal to the bzr process specifically, for example by typing
2903
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
2905
* ``bzr check`` in pack-0.92, 1.6 and 1.9 format repositories will no
2906
longer report incorrect errors about ``Missing inventory ('TREE_ROOT', ...)``
2907
(Robert Collins, #416732)
2909
* ``bzr info -v`` on a 2a format still claimed that it was a "Development
2910
format" (John Arbash Meinel, #424392)
2912
* ``bzr log stacked-branch`` shows the full log including
2913
revisions that are in the fallback repository. (Regressed in 2.0rc1).
2914
(John Arbash Meinel, #419241)
2916
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
2917
traceback. (Martin Pool, #109115)
2919
* Conversion to 2a will create a single pack for all the new revisions (as
2920
long as it ran without interruption). This improves both ``bzr upgrade``
2921
and ``bzr pull`` or ``bzr merge`` from local branches in older formats.
2922
The autopack logic that occurs every 100 revisions during local
2923
conversions was not returning that pack's identifier, which resulted in
2924
the partial packs created during the conversion not being consolidated
2925
at the end of the conversion process. (Robert Collins, #423818)
2927
* Fetches from 2a to 2a are now again requested in 'groupcompress' order.
2928
Groups that are seen as 'underutilized' will be repacked on-the-fly.
2929
This means that when the source is fully packed, there is minimal
2930
overhead during the fetch, but if the source is poorly packed the result
2931
is a fairly well packed repository (not as good as 'bzr pack' but
2932
good-enough.) (Robert Collins, John Arbash Meinel, #402652)
2934
* Fix a potential segmentation fault when doing 'log' of a branch that had
2935
ghosts in its mainline. (Evaluating None as a tuple is bad.)
2936
(John Arbash Meinel, #419241)
2938
* ``groupcompress`` sort order is now more stable, rather than relying on
2939
``topo_sort`` ordering. The implementation is now
2940
``KnownGraph.gc_sort``. (John Arbash Meinel)
2942
* Local data conversion will generate correct deltas. This is a critical
2943
bugfix vs 2.0rc1, and all 2.0rc1 users should upgrade to 2.0rc2 before
2944
converting repositories. (Robert Collins, #422849)
2946
* Network streams now decode adjacent records of the same type into a
2947
single stream, reducing layering churn. (Robert Collins)
2949
* Prevent some kinds of incomplete data from being committed to a 2a
2950
repository, such as revisions without inventories, a missing chk_bytes
2951
record for an inventory, or a missing text referenced by an inventory.
2952
(Andrew Bennetts, #423506, #406687)
2957
* Fix assertion error about "_remember_remote_is_before" when pushing to
2958
older smart servers.
2959
(Andrew Bennetts, #418931)
2961
* Help on hooks no longer says 'Not deprecated' for hooks that are
2962
currently supported. (Ian Clatworthy, #422415)
2964
* PDF and CHM (Windows HtmlHelp) formats are now supported for the
2965
user documentation. The HTML documentation is better broken up into
2966
topics. (Ian Clatworthy)
2968
* The developer and foreign language documents are now separated
2969
out so that searching in the HTML and CHM files produces more
2970
useful results. (Ian Clatworthy)
2972
* The main table of contents now provides links to the new Migration Docs
2973
and Plugins Guide. (Ian Clatworthy)
2979
:Codename: no worries
2980
:2.0.0rc1: 2009-08-26
2982
Compatibility Breaks
2983
********************
2985
* The default format for bzr is now ``2a``. This format brings many
2986
significant performance and size improvements. bzr can pull from
2987
any existing repository into a ``2a`` one, but can only transfer
2988
from ``2a`` into ``rich-root`` repositories. The Upgrade guide
2989
has more information about this change. (Robert Collins)
2991
* On Windows auto-detection of Putty's plink.exe is disabled.
2992
Default SSH client for Windows is paramiko. User still can force
2993
usage of plink if explicitly set environment variable BZR_SSH=plink.
2994
(#414743, Alexander Belchenko)
2999
* ``bzr branch --switch`` can now switch the checkout in the current directory
3000
to the newly created branch. (Lukáš Lalinský)
3005
* Further tweaks to handling of ``bzr add`` messages about ignored files.
3006
(Jason Spashett, #76616)
3008
* Fetches were being requested in 'groupcompress' order, but weren't
3009
recombining the groups. Thus they would 'fragment' to get the correct
3010
order, but not 'recombine' to actually benefit from it. Until we get
3011
recombining to work, switching to 'unordered' fetches avoids the
3012
fragmentation. (John Arbash Meinel, #402645)
3014
* Fix a pycurl related test failure on karmic by recognizing an error
3015
raised by newer versions of pycurl.
3016
(Vincent Ladeuil, #306264)
3018
* Fix a test failure on karmic by making a locale test more robust.
3019
(Vincent Ladeuil, #413514)
3021
* Fix IndexError printing CannotBindAddress errors.
3022
(Martin Pool, #286871)
3024
* Fix "Revision ... not present" errors when upgrading stacked branches,
3025
or when doing fetches from a stacked source to a stacked target.
3026
(Andrew Bennetts, #399140)
3028
* ``bzr branch`` of 2a repositories over HTTP is much faster. bzr now
3029
batches together small fetches from 2a repositories, rather than
3030
fetching only a few hundred bytes at a time.
3031
(Andrew Bennetts, #402657)
3036
* A better description of the platform is shown in crash tracebacks, ``bzr
3037
--version`` and ``bzr selftest``.
3038
(Martin Pool, #409137)
3040
* bzr can now (again) capture crash data through the apport library,
3041
so that a single human-readable file can be attached to bug reports.
3042
This can be disabled by using ``-Dno_apport`` on the command line, or by
3043
putting ``no_apport`` into the ``debug_flags`` section of
3045
(Martin Pool, Robert Collins, #389328)
3047
* ``bzr push`` locally on windows will no longer give a locking error with
3048
dirstate based formats. (Robert Collins)
3050
* ``bzr shelve`` and ``bzr unshelve`` now work on windows.
3051
(Robert Collins, #305006)
3053
* Commit of specific files no longer prevents using the iter_changes
3054
codepath. On 2a repositories, commit of specific files should now be as
3055
fast, or slightly faster, than a full commit. (Robert Collins)
3057
* The internal core code that handles specific file operations like
3058
``bzr st FILENAME`` or ``bzr commit FILENAME`` has been changed to
3059
include the parent directories if they have altered, and when a
3060
directory stops being a directory its children are always included. This
3061
fixes a number of causes for ``InconsistentDelta`` errors, and permits
3062
faster commit of specific paths. (Robert Collins, #347649)
3067
* New developer documentation for content filtering.
3073
* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its
3074
classes changed to manage lock lifetime of the trees they open in a way
3075
consistent with reader-exclusive locks. (Robert Collins, #305006)
3083
:Codename: nein nein nein!
3086
This release fixes two small but worthwhile bugs relevant to users on
3087
Microsoft Windows: some commands that failed on with locking errors will
3088
now work, and a bug that caused poor performance after committing a file
3089
with line-ending conversion has now been fixed. It also fixes a bug in
3090
pushing to older servers.
3095
* Fixed a problem where using content filtering and especially end-of-line
3096
conversion will commit too many copies a file.
3097
(Martin Pool, #415508)
3099
* Fix assertion error about ``_remember_remote_is_before`` in
3100
``set_tags_bytes`` when pushing to older smart servers.
3101
(Andrew Bennetts, Alexander Belchenko, #418931)
3106
* ``bzr push`` locally on Windows will no longer give a locking error with
3107
dirstate based formats. (Robert Collins)
3109
* ``bzr shelve`` and ``bzr unshelve`` now work on Windows.
3110
(Robert Collins, #305006)
3115
* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its
3116
classes changed to manage lock lifetime of the trees they open in a way
3117
consistent with reader-exclusive locks. (Robert Collins, #305006)
3119
* ``Tree.path_content_summary`` may return a size of None, when called on
3120
a tree with content filtering where the size of the canonical form
3121
cannot be cheaply determined. (Martin Pool)
3123
* When manually creating transport servers in test cases, a new helper
3124
``TestCase.start_server`` that registers a cleanup and starts the server
3125
should be used. (Robert Collins)
3130
Compatibility Breaks
3131
********************
3133
* Committing directly to a stacked branch from a lightweight checkout will
3134
no longer work. In previous versions this would appear to work but would
3135
generate repositories with insufficient data to create deltas, leading
3136
to later errors when branching or reading from the repository.
3137
(Robert Collins, bug #375013)
3145
* Fetching from 2a branches from a version-2 bzr protocol would fail to
3146
copy the internal inventory pages from the CHK store. This cannot happen
3147
in normal use as all 2a compatible clients and servers support the
3148
version-3 protocol, but it does cause test suite failures when testing
3149
downlevel protocol behaviour. (Robert Collins)
3151
* Fix a test failure on karmic by making a locale test more robust.
3152
(Vincent Ladeuil, #413514)
3154
* Fixed "Pack ... already exists" error when running ``bzr pack`` on a
3155
fully packed 2a repository. (Andrew Bennetts, #382463)
3157
* Further tweaks to handling of ``bzr add`` messages about ignored files.
3158
(Jason Spashett, #76616)
3160
* Properly handle fetching into a stacked branch while converting the
3161
data, especially when there are also ghosts. The code was filling in
3162
parent inventories incorrectly, and also not handling when one of the
3163
parents was a ghost. (John Arbash Meinel, #402778, #412198)
3165
* ``RemoteStreamSource.get_stream_for_missing_keys`` will fetch CHK
3166
inventory pages when appropriate (by falling back to the vfs stream
3167
source). (Andrew Bennetts, #406686)
3169
* StreamSource generates rich roots from non-rich root sources correctly
3170
now. (Andrew Bennetts, #368921)
3172
* When deciding whether a repository was compatible for upgrading or
3173
fetching, we previously incorrectly checked the default repository
3174
format for the bzrdir format, rather than the format that was actually
3175
present on disk. (Martin Pool, #408824)
3180
* A better description of the platform is shown in crash tracebacks, ``bzr
3181
--version`` and ``bzr selftest``.
3182
(Martin Pool, #409137)
3184
* Cross-format fetches (such as between 1.9-rich-root and 2a) via the
3185
smart server are more efficient now. They send inventory deltas rather
3186
than full inventories. The smart server has two new requests,
3187
``Repository.get_stream_1.19`` and ``Repository.insert_stream_1.19`` to
3188
support this. (Andrew Bennetts, #374738, #385826)
3190
* Extracting the full ancestry and computing the ``merge_sort`` is now
3191
significantly faster. This effects things like ``bzr log -n0``. (For
3192
example, ``bzr log -r -10..-1 -n0 bzr.dev`` is 2.5s down to 1.0s.
3193
(John Arbash Meinel)
3204
* ``-Dstrict_locks`` can now be used to check that read and write locks
3205
are treated properly w.r.t. exclusivity. (We don't try to take an OS
3206
read lock on a file that we already have an OS write lock on.) This is
3207
now set by default for all tests, if you have a test which cannot be
3208
fixed, you can use ``self.thisFailsStrictLockCheck()`` as a
3209
compatibility knob. (John Arbash Meinel)
3211
* InterDifferingSerializer is now only used locally. Other fetches that
3212
would have used InterDifferingSerializer now use the more network
3213
friendly StreamSource, which now automatically does the same
3214
transformations as InterDifferingSerializer. (Andrew Bennetts)
3216
* ``KnownGraph`` now has a ``.topo_sort`` and ``.merge_sort`` member which
3217
are implemented in pyrex and significantly faster. This is exposed along
3218
with ``CombinedGraphIndex.find_ancestry()`` as
3219
``VersionedFiles.get_known_graph_ancestry(keys)``.
3220
(John Arbash Meinel)
3222
* RemoteBranch.open now honours ignore_fallbacks correctly on bzr-v2
3223
protocols. (Robert Collins)
3225
* The index code now has some specialized routines to extract the full
3226
ancestry of a key in a more efficient manner.
3227
``CombinedGraphIndex.find_ancestry()``. (Time to get ancestry for
3228
bzr.dev drops from 1.5s down to 300ms. For OOo from 33s => 10.5s) (John
3234
* Install the test ssl certificate and key so that installed bzr
3235
can run the https tests. (Denys Duchier, #392401)

3243
:1.18rc1: 2009-08-10
3245
This release of Bazaar marches on towards the 2.0 release in which the 2a
3246
'brisbane-core' format becomes generally recommended. Most of the work in
3247
this release now focusses on bug fixes and stabilization, covering both 2a
3248
and previous formats. There is a new text-mode interactive merge feature,
3249
a new guide to migration to 2a format in the user documentation, and
3250
pushing branches to a smart server is now much faster.
3252
The Bazaar team decided that 2.0 will be a long-term supported release,
3253
with bugfix-only releases based on it continuing for at least six months
3254
or until the following stable release.
3256
There are no changes from 1.18rc1 to 1.18.
3261
* ``bzr merge --interactive`` applies a user-selected portion of the
3262
merge. The UI is similar to ``shelve``. (Aaron Bentley)
3264
* ``bzr reconfigure`` now takes options ``--stacked-on URL`` and
3265
``--unstacked`` to change stacking of a branch.
3266
(Martin Pool, #391411)
3271
* Annotating on a stacked branch will now succeed in simple scenarios.
3272
There are still some complex scenarios where it will fail (bug #399884)
3273
(John Arbash Meinel, #393366)
3275
* A progress bar is no longer left dangling when ``bzr selftest``
3276
completes, and the progress bar updates with zero latency so the
3277
displayed test name is always the one that's actually running.
3278
(Martin Pool, #123688)
3280
* Authenticating against an ssh server now uses ``auth_none`` to determine
3281
if password authentication is even supported. This fixes a bug where
3282
users would be prompted for a launchpad password, even though launchpad
3283
only supports publickey authentication. (John Arbash Meinel, #375867)
3285
* BranchBuilder now accepts timezone to avoid test failures in countries far
3286
from GMT. (Vincent Ladeuil, #397716)
3288
* ``bzr commit`` no longer saves the unversioning of missing files until
3289
the commit has completed on the branch. This means that aborting a
3290
commit that found a missing file will leave the tree unedited.
3291
(Robert Collins, #282402)
3293
* ``bzr mv`` no longer takes out branch locks, which allows it to work
3294
when the branch is readonly. (Robert Collins, #216541)
3296
* ``bzr revert .`` no longer generates an InconsistentDelta error when
3297
there are missing subtrees. (Robert Collins, #367632)
3299
* ``bzr send`` now generates valid bundles with ``--2a`` formats. However,
3300
do to internal changes necessary to support this, older clients will
3301
fail when trying to insert them. For newer clients, the bundle can be
3302
used to apply the changes to any rich-root compatible format.
3303
(John Arbash Meinel, #393349)
3305
* Cope with FTP servers that don't support restart/append by falling back
3306
to reading and then rewriting the whole file, such as TahoeLAFS. (This
3307
fallback may be slow for some access patterns.) (Nils Durner, #294709)
3309
* Encode the paths in ``mbcs`` encoding on Windows when spawning an
3310
external diff client. This at least allows supporting filenames that are
3311
not ascii, but are present in the current locale. Ideally we would be
3312
able to pass the Unicode path, but that would be client dependent.
3313
(John Arbash Meinel, #382709)
3315
* Fix a compile bug on Solaris having to do with const and
3316
pointer-to-pointers. (John Arbash Meinel, #408441)
3318
* Fixed a NameError that occurs when merging or pulling from a URL that
3319
causes a redirection loop when bzr tries to read a URL as a bundle.
3320
(Andrew Bennetts, #400847)
3322
* Fix ``AttributeError: 'TestUIFactory' object has no attribute 'tick'``
3323
running send and similar commands on 2a formats.
3324
(Martin Pool, #408201)
3326
* Fix crash in some invocations of ``bzr status`` in format 2a.
3327
(Martin Pool, #403523)
3329
* Fixed export to existing directory: if directory is empty then export
3330
will succeed, otherwise it fails with error.
3331
(Alexander Belchenko, #406174)
3333
* Fixed spurious "Source branch does not support stacking" warning when
3334
pushing. (Andrew Bennetts, #388908)
3336
* Fixed spurious transport activity indicator appearing while tests are
3337
running. (Martin Pool, #343532)
3339
* Merge now correctly handles empty right-hand revision specs.
3340
(Aaron Bentley, #333961)
3342
* Renames to lexographically lower basenames in trees that have never been
3343
committed to will no longer corrupt the dirstate. This was caused by an
3344
bug in the dirstate update_minimal method. (Robert Collins, #395556)
3346
* Requests for unknown methods no longer cause the smart server to log
3347
lots of backtraces about ``UnknownSmartMethod``, ``do_chunk`` or
3348
``do_end``. (Andrew Bennetts, #338561)
3350
* Shelve will not shelve the initial add of the tree root. (Aaron Bentley)
3352
* Streaming from bzr servers where there is a chain of stacked branches
3353
(A stacked on B stacked on C) will now work. (Robert Collins, #406597)
3355
* The environment variable ``BZR_PROGRESS_BAR`` set to either ``text`` or ``none``
3356
always forces progress bars either on or off respectively. Otherwise,
3357
they're turned on if ``TERM`` is not ``dumb`` and stderr is a terminal.
3358
bzr always uses the 'text' user interface when run as a command, so
3359
``BZR_USE_TEXT_UI`` is no longer needed.
3360
(Martin Pool, #339385, #387717)
3362
* The optional ``_knit_load_data_pyx`` C extension was never being
3363
imported. This caused significant slowdowns when reading data from
3364
repositories. (Andrew Bennetts, #405653)
3366
* The ``--hardlink`` option to ``branch`` and ``checkout`` is not
3367
supported at the moment on workingtree formats that can do content
3368
filtering. (See <https://bugs.edge.launchpad.net/bzr/+bug/408193>.)
3369
bzr now says so, rather than just ignoring the option. (Martin Pool)
3371
* There was a bug in ``osutils.relpath`` that was only triggered on
3372
Windows. Essentially if you were at the root of a drive, and did
3373
something to a branch/repo on another drive, we would go into an
3374
infinite loop while trying to find a 'relative path'.
3375
(John Arbash Meinel, #394227)
3377
* ``WorkingTree4.unversion`` will no longer fail to unversion ids which
3378
were present in a parent tree but renamed in the working tree.
3379
(Robert Collins, #187207)
3384
* Can now rename/move files even if they have been removed from the inventory.
3387
* Pushing branches with tags via ``bzr://`` and ``bzr+ssh://`` is much
3388
faster, using a new ``Branch.set_tags_bytes`` smart server verb rather
3389
than VFS methods. For example, pushes of small branches with tags take
3390
11 rather than 18 smart server requests. (Andrew Bennetts, #398608)
3392
* Sending Ctrl-Break on Windows will now drop you into the debugger, in
3393
the same way that sending Ctrl-\\ does on other platforms.
3394
(John Arbash Meinel)
3399
* Added Bazaar 2.0 Upgrade Guide. (Ian Clatworthy)
3404
* ``CLIUIFactory`` is deprecated; use ``TextUIFactory`` instead if you
3405
need to subclass or create a specific class, or better yet the existing
3406
``make_ui_for_terminal``. ``SilentUIFactory`` is clarified to do no
3407
user interaction at all, rather than trying to read from stdin but not
3408
writing any output, which would be strange if reading prompts or
3409

3411
* New TransformPreview.commit() allows committing without a working tree.
3414
* ``pb`` parameter to ``TextTestResult`` is deprecated and ignored.
3417
* ProgressTasks now prefer to talk direct to their ProgressView not to the
3421
* ``WorkingTree._check`` now requires a references dict with keys matching
3422
those returned by ``WorkingTree._get_check_refs``. (Robert Collins)
3427
* ``CHKInventory.path2id`` uses the parent_id to basename hash to avoid
3428
reading the entries along the path, reducing work to lookup ids from
3429
paths. (Robert Collins)
3431
* ``CHKMap.apply_delta`` now raises ``InconsistentDelta`` if a delta adds
3432
as new a key which was already mapped. (Robert Collins)
3434
* Inventory delta application catches more cases of corruption and can
3435
prevent corrupt deltas from affecting consistency of data structures on
3436
disk. (Robert Collins)
3438
* --subunit support now adds timestamps if the subunit version supports
3439
it. (Robert Collins)
3441
* The Windows all-in-one installer now bundles the PyQt image format
3442
plugins, which allows previewing more images as part of 'qdiff'.
3443
(Alexander Belchenko)
3449
* Merge directive cherrypick tests must use the same root id.
3450
(Martin Pool, #409684)
3452
* Spurious failure in ``check`` tests on rich-root formats fixed.
3453
(Martin Pool, #408199)
3455
* The ``bzrlib.tests.TextTestRunner`` will no longer call
3456
``countTestsCases`` on the test being run. Progress information is
3457
instead handled by having the test passed in call ``result.progress``
3458
before running its contents. This improves the behaviour when using
3459
``TextTestRunner`` with test suites that don't support
3460
``countTestsCases``. (Robert Collins)

3469
* The optional ``_knit_load_data_pyx`` C extension was never being
3470
imported. This caused significant slowdowns when reading data from
3471
knit format repositories. (Andrew Bennetts, #405653)

:1.17rc1: 2009-07-13
3481
Bazaar continues to blaze a straight and shining path to the 2.0 release and
3482
the elevation of the ``2a`` beta format to the full glory of "supported and
3485
Highlights in this release include greatly reduced memory consumption during
3486
commits, faster ``ls``, faster ``annotate``, faster network operations if
3487
you're specifying a revision number and the final destruction of those
3488
annoying progress bar artifacts.
3491
Changes from 1.17rc1 to 1.17final
3492
*********************************
3494
* Change an extension to call the python ``frozenset()`` rather than the C
3495
api ``PyFrozenSet_New``. It turns out that python2.4 did not expose the
3496
C api. (John Arbash Meinel, #399366)
3498
* Fixes for the Makefile and the rename of ``generate_docs.py`` to
3499
``tools/generate_docs.py`` to allow everything to be built on Windows.
3500
(John Arbash Meinel, #399356)
3502
* ``bzr serve`` once again applies a ``ChrootServer`` to the given
3503
directory before serving it. (Andrew Bennetts, #400535)
3506
Compatibility Breaks
3507
********************
3509
* ``bzr register-branch`` from the Launchpad plugin now refers to "project"
3510
instead of "product" which is the correct Launchpad terminology. The
3511
--product option is deprecated and users should switch to using --project.
3512
(Neil Martinsen-Burrell, #238764)
3518
* ``bzr push`` now aborts if uncommitted changes (including pending merges)
3519
are present in the working tree (if one is present) and no revision is
3520
specified. The configuration option ``push_strict`` can be used to set the
3521
default for this behavior. (Vincent Ladeuil, #284038, #322808, #65286)
3523
* ``bzr revno`` and ``bzr revision-info`` now have a ``--tree`` option to
3524
show revision info for the working tree instead of the branch.
3525
(Matthew Fuller, John Arbash Meinel)
3527
* ``bzr send`` now aborts if uncommitted changes (including pending merges)
3528
are present in the working tree and no revision is specified. The
3529
configuration option ``send_strict`` can be used to set the default for this
3531
(Vincent Ladeuil, #206577)
3533
* ``bzr switch --create-branch/-b`` can now be used to create and switch
3534
to a new branch. Supplying a name without a ``/`` will create the branch
3535
relative to the existing branch. (similar to how ``bzr switch name``
3536
works when the branch already exists.) (John Arbash Meinel)
3542
* Accept uppercase "Y/N" to prompts such as from break lock.
3543
(#335182, Tim Powell, Martin Pool)
3545
* Add documentation about diverged branches and how to fix them in the
3546
centralized workflow with local commits. Mention ``bzr help
3547
diverged-branches`` when a push fails because the branches have
3548
diverged. (Neil Martinsen-Burrell, #269477)
3550
* Annotate would sometimes 'latch on' to trivial lines, causing important
3551
lines to be incorrectly annotated. (John Arbash Meinel, #387952)
3553
* Automatic format upgrades triggered by default stacking policies on a
3554
1.16rc1 (or later) smart server work again.
3555
(Andrew Bennetts, #388675)
3557
* Avoid progress bar artifacts being left behind on the screen.
3558
(Martin Pool, #321935)
3560
* Better message in ``bzr split`` error suggesting a rich root format.
3561
(Neil Martinsen-Burrell, #220067)
3563
* ``Branch.set_append_revisions_only`` now works with branches on a smart
3564
server. (Andrew Bennetts, #365865)
3566
* By default, ``bzr branch`` will fail if the target directory exists, but
3567
does not already have a control directory. The flag ``--use-existing-dir``
3568
will allow operation to proceed. (Alexander Belchenko, #307554)
3570
* ``bzr ls DIR --from-root`` now shows only things in DIR, not everything.
3573
* Fetch between repositories does not error if they have inconsistent data
3574
that should be irrelevant to the fetch operation. (Aaron Bentley)
3576
* Fix ``AttributeError`` exception when reconfiguring lightweight checkout
3577
of a remote repository.
3578
(Jelmer Vernooij, #332194)
3580
* Fix bug in decoding v3 smart server messages when receiving multiple
3581
lots of excess bytes after an end-of-message.
3584
* Force deletion of readonly files during merge, update and other tree
3586
(Craig Hewetson, Martin Pool, #218206)
3588
* Force socket shutdown in threaded http test servers to avoid client hangs
3589
(pycurl). (Vincent Ladeuil, #383920).
3591
* ``LRUCache`` will maintain the linked list pointers even if a nodes
3592
cleanup function raises an exception. (John Arbash Meinel, #396838)
3594
* Progress bars are now suppressed again when the environment variable
3595
``BZR_PROGRESS_BAR`` is set to ``none``.
3596
(Martin Pool, #339385)
3598
* Reduced memory consumption during ``bzr commit`` of large files. For
3599
pre 2a formats, should be down to ~3x the size of a file.
3600
For ``--2a`` format repositories, it is down to the size of the file
3601
content plus the size of the compressed text. Related to bug #109114.
3602
(John Arbash Meinel)
3604
* Set hidden attribute on .bzr directory below unicode path should never
3605
fail with error. The operation should succeed even if bzr unable to set
3606
the attribute. (Alexander Belchenko, related to bug #335362).
3608
* Stacking will no longer accept requests to stack on the same
3609
branch/repository. Existing branches that incorrectly reference the same
3610
repository in a stacking configuration will now raise
3611
UnstackableLocationError when the branch is opened. This can be fixed by
3612
removing the stacking location inside ``.bzr/branch``.
3613
(Robert Collins, #376243)
3615
* The ``log+`` decorator, useful in debugging or profiling, could cause
3616
"AttributeError: 'list' object has no attribute 'next'". This is now
3617
fixed. The log decorator no longer shows the elapsed time or transfer
3618
rate because they're available in the log prefixes and the transport
3619
activity display respectively.
3620
(Martin Pool, #340347)
3622
* Unshelve works correctly when multiple zero-length files are present on
3623
the shelf. (Aaron Bentley, #363444)
3625
* Progress bars no longer show the network transport scheme or direction.
3628
* launchpad-login now respects the 'verbose' option.
3629
(Jonathan Lange, #217031)
3635
* ``bzrlib.user_encoding`` is now officially deprecated. It is not
3636
possible to write a deprecation wrapper, but the variable will be
3637
removed in the near future. Use ``bzrlib.osutils.get_user_encoding()``
3638
instead. (Alexander Belchenko)
3640
* Command lookup has had hooks added. ``bzrlib.Command.hooks`` has
3641
three new hook points: ``get_command``, ``get_missing_command`` and
3642
``list_commands``, which allow just-in-time command name provision
3643
rather than requiring all command names be known a-priori.
3646
* ``get_app_path`` from win32utils.py now supports REG_EXPAND_SZ data type
3647
and can read path to wordpad.exe. (Alexander Belchenko, #392046)
3649
* ``graph.KnownGraph`` has been added. This is a class that can give
3650
answers to ``heads()`` very quickly. However, it has the assumption that
3651
the whole graph has already been loaded. This is true during
3652
``annotate`` so it is used there with good success (as much as 2x faster
3653
for files with long ancestry and 'cherrypicked' changes.)
3654
(John Arbash Meinel, Vincent Ladeuil)
3656
* OS file locks are now taken out using ``CreateFile`` rather than
3657
``LockFileEx`` on Windows. The locking remains exclusive with
3658
``LockFileEx`` but now it also works on older versions of Windows (such
3659
as Win98). (Martin <gzlist>)
3661
* pack <=> pack fetching is now done via a ``PackStreamSource`` rather
3662
than the ``Packer`` code. The user visible change is that we now
3663
properly fetch the minimum number of texts for non-smart fetching.
3664
(John Arbash Meinel)
3667
* ``VersionedFiles._add_text`` is a new api that lets us insert text into
3668
the repository as a single string, rather than a list of lines. This can
3669
improve memory overhead and performance of committing large files.
3670
(Currently a private api, used only by commit). (John Arbash Meinel)
3676
* ``bzr annotate`` can now be significantly faster. The time for
3677
``bzr annotate NEWS`` is down to 7s from 22s in 1.16. Files with long
3678
histories and lots of 'duplicate insertions' will be improved more than
3679
others. (John Arbash Meinel, Vincent Ladeuil)
3681
* ``bzr ls`` is now faster. On OpenOffice.org, the time drops from 2.4
3682
to 1.1 seconds. The improvement for ``bzr ls -r-1`` is more
3683
substantial dropping from 54.3 to 1.1 seconds. (Ian Clatworthy)
3685
* Improve "Path(s) are not versioned" error reporting for some commands.
3688
* Initial commit performance in ``--2a`` repositories has been improved by
3689
making it cheaper to build the initial CHKMap. (John Arbash Meinel)
3691
* Resolving a revno to a revision id on a branch accessed via ``bzr://``
3692
or ``bzr+ssh://`` is now much faster and involves no VFS operations.
3693
This speeds up commands like ``bzr pull -r 123``. (Andrew Bennetts)
3695
* ``revision-info`` now properly aligns the revnos/revids in the output
3696
and doesn't traceback when given revisions not in the current branch.
3697
Performance is also significantly improved when requesting multiple revs
3698
at once. (Matthew Fuller, John Arbash Meinel)
3700
* Tildes are no longer escaped by Transports. (Andy Kilner)
3706
* Avoid bad text wrapping in generated documentation. Slightly better
3707
formatting in the user reference.
3708
(Martin Pool, #249908)
3710
* Minor clarifications to the help for End-Of-Line conversions.
3716
* Removed overspecific error class ``InvalidProgressBarType``.
3719
* The method ``ProgressView._show_transport_activity`` is now
3720
``show_transport_activity`` because it's part of the contract between
3721
this class and the UI. (Martin Pool)
3727
:Released: 2009-06-26
3729
End user testing of the 2a format revealed two serious bugs. The first,
3730
#365615, caused bzr to raise AbsentContentFactory errors when autopacking.
3731
This meant that commits or pushes to 2a-format repositories failed
3734
The second bug, #390563, caused the smart server to raise AbsentContentFactory
3735
when streaming 2a stacked 2a-format branches. This particularly affected
3736
branches stored on Launchpad in the 2a format.
3738
Both of these bugs cause command failures only, neither of them cause data
3739
corruption or data loss. And, of course, both of these bugs are now fixed.
3744
* We now properly request a more minimal set of file texts when fetching
3745
multiple revisions. (Robert Collins, John Arbash Meinel, #390563)
3747
* Repositories using CHK pages (which includes the new 2a format) will no
3748
longer error during commit or push operations when an autopack operation
3749
is triggered. (Robert Collins, #365615)
3751
* ``chk_map.iter_interesting_nodes`` now properly uses the *intersection*
3752
of referenced nodes rather than the *union* to determine what
3753
uninteresting pages we still need to look at. Prior to this,
3754
incrementally pushing to stacked branch would push the minimal data, but
3755
fetching everything would request extra texts. There are some unhandled
3756
cases wrt trees of different depths, but this fixes the common cases.
3757
(Robert Collins, John Arbash Meinel, #390563)
3759
* ``GroupCompress`` repositories now take advantage of the pack hints
3760
parameter to permit cross-format fetching to incrementally pack the
3761
converted data. (Robert Collins)
3763
* ``Repository.commit_write_group`` now returns opaque data about what
3764
was committed, for passing to the ``Repository.pack``. Repositories
3765
without atomic commits will still return None. (Robert Collins)
3767
* ``Repository.pack`` now takes an optional ``hint`` parameter
3768
which will support doing partial packs for repositories that can do
3769
that. (Robert Collins)
3771
* RepositoryFormat has a new attribute 'pack_compresses' which is True
3772
when doing a pack operation changes the compression of content in the
3773
repository. (Robert Collins)
3775
* ``StreamSink`` and ``InterDifferingSerialiser`` will call
3776
``Repository.pack`` with the hint returned by
3777
``Repository.commit_write_group`` if the formats were different and the
3778
repository can increase compression by doing a pack operation.

3788
This version of Bazaar contains the beta release of the new ``2a`` repository
3789
format, suitable for testing by fearless, advanced users. This format or an
3790
updated version of it will become the default format in Bazaar 2.0. Please
3791
read the NEWS entry before even thinking about upgrading to the new format.
3793
Also included are speedups for many operations on huge projects, a bug fix for
3794
pushing stacked new stacked branches to smart servers and the usual bevy of
3795
bug fixes and improvements.
