:2.1.4: NOT RELEASED YET
22
* Skip tests that needs a bzr source tree when there isn't one. This is
23
needed to succesfully run the test suite for installed versions.
24
(Vincent Ladeuil, #644855).
26
* Skip the tests that requires respecting the chmod bits when running as root.
27
(Vincent Ladeuil, #646133)
51
The third release in our 2.1 series addresses several user-inconvenience bugs
52
(and includes the fixes done in 2.0.6). None are critical, but upgrading is
53
recommended for all users on earlier 2.1 releases.
58
* Additional merges after an unrelated branch has been merged with its
59
history no longer crash when deleted files are involved.
60
(Vincent Ladeuil, John Arbash Meinel, #375898)
62
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
63
previously-unversioned directory within the tree: the directory is
65
(Martin Pool, #192859)
67
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
68
target of the symlink.
69
(Martin Pool, John Arbash Meinel, #128562)
71
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
72
permissions as ``.bzr`` directory on a POSIX OS.
73
(Parth Malwankar, #262450)
75
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
76
way which should help avoid problems with concurrent writers.
77
(Vincent Ladeuil, #525571)
79
* Don't traceback trying to unversion children files of an already
80
unversioned directory. (Vincent Ladeuil, #494221)
82
* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
83
contains only NUL bytes). Instead warn the user, and allow ``bzr
84
break-lock`` to remove it. (Andrew Bennetts, #619872)
86
* Fix ``AttributeError on parent.children`` when adding a file under a
87
directory that was a symlink in the previous commit.
88
(Martin Pool, #192859)
90
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
91
which can result in "missing referenced chk root keys" errors when
92
fetching from repositories with affected revisions.
93
(Andrew Bennetts, #522637)
95
* Raise ValueError instead of a string exception.
96
(John Arbash Meinel, #586926)
98
* Reduce peak memory by one copy of compressed text.
99
(John Arbash Meinel, #566940)
101
* Repositories accessed via a smart server now reject being stacked on a
102
repository in an incompatible format, as is the case when accessing them
103
via other methods. This was causing fetches from those repositories via
104
a smart server (e.g. using ``bzr branch``) to receive invalid data.
105
(Andrew Bennetts, #562380)
107
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
108
error. This error was caused by 2.0 not being updated when upstream
109
python merged the end of run patch, which chose ``stopTestRun`` rather than
110
``done``. (Robert Collins, #571437)
112
* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``
113
being thrown from ``xml_serializer`` on certain cElementTree setups.
114
(Martin [gz], #254278)
116
* When passing a file to ``UTF8DirReader`` make sure to close the current
117
directory file handle after the chdir fails. Otherwise when passing many
118
filenames into a command line ``bzr status`` we would leak descriptors.
119
(John Arbash Meinel, #583486)
124
* ``build_tree_contents`` can create symlinks.
125
(Martin Pool, John Arbash Meinel)
133
This release fixes two critical networking issues with older servers and
134
with interrupted system call errors when pushing or pulling. We recommend
135
upgrading to anyone running a 2.1.x version of bzr.
140
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
141
support of bzr-externals and scmproj plugins.
142
(Alexander Belchenko, bug #572098)
144
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
145
(Aaron Bentley, #559436)
147
* Do not register a SIGWINCH signal handler, instead just poll for the
148
terminal width as needed. This avoids the "Interrupted System Call"
149
problems that occur on POSIX with all currently released versions of
151
(Andrew Bennetts, #583941)
153
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
155
(Andrew Bennetts, #528041)
157
* Reset ``siginterrupt`` flag to False every time we handle a signal
158
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
159
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
160
errors compared to registering ``signal.signal`` directly.
163
* Reduce peak memory by one copy of compressed text.
164
(John Arbash Meinel, #566940)
166
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
167
(John Arbash Meinel, #582656)
169
* When passing a file to ``UTF8DirReader`` make sure to close the current
170
directory file handle after the chdir fails. Otherwise when passing many
171
filenames into a command line ``bzr status`` we would leak descriptors.
172
(John Arbash Meinel, #583486)
177
* ``_remember_remote_is_before`` no longer raises AssertionError when
178
suboptimal network behaviour is noticed; instead it just mutters to the
179
log file (and warns the user if they have set the ``hpss`` debug flag).
180
This was causing unnecessary aborts for performance bugs that are minor
182
(Andrew Bennetts, #528041)
190
This is a small bugfix release. Upgrading is recommended for anyone
191
running 2.1.0 or earlier.
196
* Allow syscalls to automatically restart when ``TextUIFactory``'s
197
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
198
IO, which are often poorly handled by Python's libraries and parts of
199
bzrlib. (Andrew Bennetts, #496813)
201
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
202
(Martin Pool, #331095)
204
* Fix plugin packaging on Windows. (Ian Clatworthy, #524162)
206
* Fix stub sftp test server to call os.getcwdu().
207
(Vincent Ladeuil, #526221, #526353)
209
* Fixed CHM generation by moving the NEWS section template into
210
a separate file. (Ian Clatworthy, #524184)
212
* Merge correctly when this_tree is not a WorkingTree. (Aaron Bentley)
214
* Register SIGWINCH handler only when creating a ``TextUIFactory``; avoids
215
problems importing bzrlib from a non-main thread.
216
(Elliot Murphy, #521989)
218
* Repositories accessed via a smart server now reject being stacked on a
219
repository in an incompatible format, as is the case when accessing them
220
via other methods. This was causing fetches from those repositories via
221
a smart server (e.g. using ``bzr branch``) to receive invalid data.
222
(Andrew Bennetts, #562380)
224
* Standardize the error handling when creating a new ``StaticTuple``
225
(problems will raise TypeError). (Matt Nordhoff, #457979)
227
* Warn if pyrex is too old to compile the new ``SimpleSet`` and
228
``StaticTuple`` extensions, rather than having the build fail randomly.
229
(John Arbash Meinel, #449776)
234
* Added a link to the Desktop Guide. (Ian Clatworthy)
236
* Added What's New in Bazaar 2.1 document. (Ian Clatworthy)
238
* Drop Google Analytics from the core docs as they caused problems
239
in the CHM files. (Ian Clatworthy, #502010)
244
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
245
can set a signal handler and call ``signal.siginterrupt(signum,
246
False)`` for it, if the platform and Python version supports it.
247
(Andrew Bennetts, #496813)
253
:Codename: Strasbourg
256
This release marks our second long-term-stable series. The Bazaar team
257
has decided that we will continue to make bugfix-only 2.0.x and 2.1.x
258
releases, along with 2.2 development releases.
260
This is a fairly incremental update, focusing on polish and bugfixing.
261
There are no changes for supported disk formats. Key updates include
262
reduced memory consumption for many operations, a new per-file merge
263
hook, ignore patterns can now include '!' to exclude files, globbing
264
support for all commands on Windows, and support for addressing home
265
directories via ``bzr+ssh://host/~/`` syntax.
267
Users are encouraged to upgrade from the 2.0 stable series.
272
* Don't require testtools to use sftp.
273
(Vincent Ladeuil, #516183)
275
* Fix "AttributeError in Inter1and2Helper" during fetch.
276
(Martin Pool, #513432)
278
* ``bzr update`` performs the two merges in a more logical order and will stop
279
when it encounters conflicts.
280
(Gerard Krol, #113809)
282
* Give a better error message when doing ``bzr bind`` in an already bound
283
branch. (Neil Martinsen-Burrell, #513063)
285
* Ignore ``KeyError`` from ``remove_index`` during ``_abort_write_group``
286
in a pack repository, which can happen harmlessly if the abort occurs during
287
finishing the write group. Also use ``bzrlib.cleanup`` so that any
288
other errors that occur while aborting the individual packs won't be
289
hidden by secondary failures when removing the corresponding indices.
290
(Andrew Bennetts, #423015)
292
* Set the mtime of files exported to a directory by ``bzr export`` all to
293
the same value to avoid confusing ``make`` and other date-based build
294
systems. (Robert Collins, #515631)
299
* Fetching into experimental formats will now print a warning. (Jelmer
305
* ``Repository.deserialise_inventory`` has been renamed to
306
``Repository._deserialise_inventory`` to indicate it is private.
309
* ``Repository.get_inventory_xml`` has been renamed to
310
``Repository._get_inventory_xml`` to indicate it is private.
313
* ``Repository.serialise_inventory`` has been renamed to
314
``Repository._serialise_inventory`` to indicate it is private.
316
* Using the ``bzrlib.chk_map`` module from within multiple threads at the
317
same time was broken due to race conditions with a module level page
318
cache. This shows up as a KeyError in the ``bzrlib.lru_cache`` code with
319
``bzrlib.chk_map`` in the backtrace, and can be triggered without using
320
the same high level objects such as ``bzrlib.repository.Repository``
321
from different threads. chk_map now uses a thread local cache which may
322
increase memory pressure on processes using threads.
323
(Robert Collins, John Arbash Meinel, #514090)
325
* The new ``merge_file_content`` should now be ok with tests to avoid
327
(Vincent Ladeuil, #515597)
332
* Use ``bzrlib.cleanup`` rather than less robust ``try``/``finally``
333
blocks in several places in ``bzrlib.merge``. This avoids masking prior
334
errors when errors like ``ImmortalPendingDeletion`` occur during cleanup
336
(Andrew Bennetts, #517275)
341
* The ``remove_index`` method of
342
``bzrlib.repofmt.pack_repo.AggregateIndex`` no longer takes a ``pack``
343
argument. This argument was always ignored.
344
(Andrew Bennetts, #423015)
349
:Codename: after the bubbles
350
:2.1.0rc2: 2010-01-29
352
This is a quick-turn-around to update a small issue with our new per-file
353
merge hook. We expect no major changes from this to the final 2.1.0.
358
* The new ``merge_file_content`` hook point has been altered to provide a
359
better API where state for extensions can be stored rather than the
360
too-simple function based approach. This fixes a performance regression
361
where branch configuration would be parsed per-file during merge. As
362
part of this the included news_merger has been refactored into a base
363
helper class ``bzrlib.merge.ConfigurableFileMerger``.
364
(Robert Collins, John Arbash Meinel, #513822)

:Codename: the 'new' stable
371
:2.1.0rc1: 2009-01-21
373
This is the first stable release candidate for Bazaar's 2.1 series. From
374
this point onwards, the 2.1 series will be considered stable (as the 2.0
375
series) and only bugfixes are expected to be incorporated. The dozen or so
376
bugfixes in the 2.0.4 release are also included in this release (along
377
with more than 15 more bugfixes). Some of the interesting features are
378
support for per-file merge hooks, ``bzr unshelve --preview``, support
379
for using ! in ignore files to exclude files from being ignored, a small
380
memory leak was squashed, and many ``ObjectNotLocked`` errors were fixed.
381
This looks to be a very good start for a new stable series.
387
* Add bug information to log output when available.
388
(Neil Martinsen-Burrell, Guillermo Gonzalez, #251729)
390
* Added ``merge_file_content`` hook point to ``Merger``, allowing plugins
391
to register custom merge logic, e.g. to provide smarter merging for
394
* Bazaar now includes the ``news_merge`` plugin. It is disabled by
395
default, to enable it add a ``news_merge_files`` option to your
396
configuration. Consult ``bzr help news_merge`` for more information.
399
* ``bzr branch`` now takes a ``--bind`` option. This lets you
400
branch and bind all in one command. (Ian Clatworthy)
402
* ``bzr switch`` now takes a ``--revision`` option, to allow switching to
403
a specific revision of a branch. (Daniel Watkins, #183559)
405
* ``bzr unshelve --preview`` can now be used to show how a patch on the
406
shelf would be applied to the working tree.
407
(Guilherme Salgado, #308122)
409
* ``bzr update`` now takes a ``--revision`` argument. This lets you
410
change the revision of the working tree to any revision in the
411
ancestry of the current or master branch. (Matthieu Moy, Mark Hammond,
414
* ``-Dbytes`` can now be used to display the total number of bytes
415
transferred for the current command. This information is always logged
416
to ``.bzr.log`` for later inspection. (John Arbash Meinel)
418
* New ignore patterns. Patterns prefixed with '!' are exceptions to
419
ignore patterns and take precedence over regular ignores. Such
420
exceptions are used to specify files that should be versioned which
421
would otherwise be ignored. Patterns prefixed with '!!' act as regular
422
ignore patterns, but have highest precedence, even over the '!'
423
exception patterns. (John Whitley, #428031)
425
* The ``supress_warnings`` configuration option has been introduced to disable
426
various warnings (it currently only supports the ``format_deprecation``
427
warning). The new option can be set in any of the following locations:
428
``bazaar.conf``, ``locations.conf`` and/or ``branch.conf``.
429
(Ted Gould, Matthew Fuller, Vincent Ladeuil)
434
* Always show a message if an OS error occurs while trying to run a
435
user-specified commit message editor.
436
(Martin Pool, #504842)
438
* ``bzr diff`` will now use the epoch when it is unable to determine
439
the timestamp of a file, if the revision it was introduced in is a
440
ghost. (Jelmer Vernooij, #295611)
442
* ``bzr switch -b`` can now create branches that are located using directory
443
services such as ``lp:``, even when the branch name doesn't contain a
444
'/'. (Neil Martinsen-Burrell, #495263)
446
* ``bzr unshelve`` has improved messages about what it is doing.
447
(Neil Martinsen-Burrell, #496917)
449
* Concurrent autopacking is more resilient to already-renamed pack files.
450
If we find that a file we are about to obsolete is already obsoleted, we
451
do not try to rename it, and we leave the file in ``obsolete_packs``.
452
The code is also fault tolerant if a file goes missing, assuming that
453
another process already removed the file.
454
(John Arbash Meinel, Gareth White, #507557)
456
* Fix "Too many concurrent requests" in reconcile when network connection
457
fails. (Andrew Bennetts, #503878)
459
* Fixed a side effect mutation of ``RemoteBzrDirFormat._network_name``
460
that caused some tests to fail when run in a non-default order.
461
Probably no user impact. (Martin Pool, #504102)
463
* Fixed ``ObjectNotLocked`` error in ``bzr cat -rbranch:../foo FILE``.
464
(Andrew Bennetts, #506274)
466
* FTP transports support Unicode paths by encoding/decoding them as utf8.
467
(Vincent Ladeuil, #472161)
469
* Listen to the SIGWINCH signal to update the terminal width.
470
(Vincent Ladeuil, #316357)
472
* Progress bars are now hidden when ``--quiet`` is given.
473
(Martin Pool, #320035)
475
* ``SilentUIFactory`` now supports ``make_output_stream`` and discards
476
whatever is written to it. This un-breaks some plugin tests that
477
depended on this behaviour.
478
(Martin Pool, #499757)
480
* When operations update the working tree, all affected files should end
481
up with the same mtime. (eg. when versioning a generated file, if you
482
update the source and the generated file together, the generated file
483
should appear up-to-date.)
484
(John Arbash Meinel, Martin <gzlist>, #488724)
489
* Added ``add_cleanup`` and ``cleanup_now`` to ``bzrlib.command.Command``.
490
All the builtin commands now use ``add_cleanup`` rather than
491
``try``/``finally`` blocks where applicable as it is simpler and more
492
robust. (Andrew Bennetts)
494
* All except a small number of storage formats are now hidden, making
495
the help for numerous commands far more digestible. (Ian Clatworthy)
497
* Attempts to open a shared repository as a branch (e.g. ``bzr branch
498
path/to/repo``) will now include "location is a repository" as a hint in
499
the error message. (Brian de Alwis, Andrew Bennetts, #440952)
501
* Push will now inform the user when they are trying to push to a foreign
502
VCS for which roundtripping is not supported, and will suggest them to
503
use dpush. (Jelmer Vernooij)
505
* The version of bzr being run is now written to the log file.
508
* Transport network activity indicator is shown more of the time when
509
Bazaar is doing network IO.
515
* Add documentation on creating merges with more than one parent.
516
(Neil Martinsen-Burrell, #481526)
518
* Better explain the --uncommitted option of merge.
519
(Neil Martinsen-Burrell, #505088)
521
* Improve discussion of pending merges in the documentation for
522
``revert``. (Neil Martinsen-Burrell, #505093)
524
* Improved help for ``bzr send``.
525
(Martin Pool, Bojan Nikolic)
527
* There is a System Administrator's Guide in ``doc/en/admin-guide``,
528
including discussions of installation, relevant plugins, security and
529
backup. (Neil Martinsen-Burrell)
531
* The ``conflicts`` help topic has been renamed to ``conflict-types``.
534
* The User Reference is now presented as a series of topics.
535
Many of the included topics have link and format tweaks applied.
541
* Added ``cachedproperty`` decorator to ``bzrlib.decorators``.
544
* Many test features were renamed from ``FooFeature`` to ``foo_feature``
545
to be consistent with instances being lower case and classes being
546
CamelCase. For the features that were more likely to be used, we added a
547
deprecation thunk, but not all. (John Arbash Meinel)
549
* Merger classes (such as ``Merge3Merger``) now expect a ``this_branch``
550
parameter in their constructors, and provide ``this_branch`` as an
551
attribute. (Andrew Bennetts)
553
* The Branch hooks pre_change_branch_tip no longer masks exceptions raised
554
by plugins - the original exceptions are now preserved. (Robert Collins)
556
* The Transport ``Server.tearDown`` method is now renamed to
557
``stop_server`` and ``setUp`` to ``start_server`` for consistency with
558
our normal naming pattern, and to avoid confusion with Python's
559
``TestCase.tearDown``. (Martin Pool)
561
* ``WorkingTree.update`` implementations must now accept a ``revision``
567
* Added ``BzrDir.open_branchV3`` smart server request, which can receive
568
a string of details (such as "location is a repository") as part of a
569
``nobranch`` response. (Andrew Bennetts, #440952)
571
* New helper osutils.UnicodeOrBytesToBytesWriter which encodes unicode
572
objects but passes str objects straight through. This is used for
573
selftest but may be useful for diff and other operations that generate
574
mixed output. (Robert Collins)
576
* New exception ``NoRoundtrippingSupport``, for use by foreign branch
577
plugins. (Jelmer Vernooij)
582
* ``bzrlib.tests.permute_for_extension`` is a helper that simplifies
583
running all tests in the current module, once against a pure python
584
implementation, and once against an extension (pyrex/C) implementation.
585
It can be used to dramatically simplify the implementation of
586
``load_tests``. (John Arbash Meinel)
588
* ``bzrlib.tests.TestCase`` now subclasses ``testtools.testcase.TestCase``.
589
This permits features in testtools such as getUniqueInteger and
590
getUniqueString to be used. Because of this, testtools version 0.9.2 or
591
newer is now a dependency to run bzr selftest. Running with versions of
592
testtools less than 0.9.2 will cause bzr to error while loading the test
593
suite. (Robert Collins)
595
* Shell-like tests now support the command "mv" for moving files. The
596
syntax for ``mv file1 file2``, ``mv dir1 dir2`` and ``mv file dir`` is
597
supported. (Neil Martinsen-Burrell)
599
* The test progress bar no longer distinguishes tests that 'errored' from
600
tests that 'failed' - they're all just failures.
607

610
The fourth beta release in the 2.1 series brings with it a significant
611
number of bugfixes (~20). The test suite is once again (finally) "green"
612
on Windows, and should remain that way for future releases. There are a
613
few performance related updates (faster upgrade and log), and several UI
614
tweaks. There has also been a significant number of tweaks to the runtime
615
documentation. 2.1.0b4 include everything from the 2.0.3 release.
621
* The BZR_SSH environmental variable may now be set to the path of a secure
622
shell client. If currently set to the value ``ssh`` it will now guess the
623
vendor of the program with that name, to restore the old behaviour that
624
indicated the SSH Corporation client use ``sshcorp`` instead as the magic
625
string. (Martin <gzlist@googlemail.com>, #176292)
630
* ``bzr commit`` now has a ``--commit-time`` option.
631
(Alexander Sack, #459276)
633
* ``-Dhpss`` now increases logging done when run on the bzr server,
634
similarly to how it works on the client. (John Arbash Meinel)
636
* New option ``bzr unshelve --keep`` applies the changes and leaves them
637
on the shelf. (Martin Pool, Oscar Fuentes, #492091)
639
* The ``BZR_COLUMNS`` envrionment variable can be set to force bzr to
640
respect a given terminal width. This can be useful when output is
641
redirected or in obscure cases where the default value is not
642
appropriate. Pagers can use it to get a better control of the line
646
* The new command ``bzr lp-mirror`` will request that Launchpad update its
647
mirror of a local branch. This command will only function if launchpadlib
655
* After renaming a file, the dirstate could accidentally reference
656
``source\\path`` rather than ``source/path`` on Windows. This might be a
657
source of some dirstate-related failures. (John Arbash Meinel)
659
* ``bzr commit`` now detects commit messages that looks like file names
660
and issues a warning.
661
(Gioele Barabucci, #73073)
663
* ``bzr ignore /`` no longer causes an IndexError. (Gorden Tyler, #456036)
665
* ``bzr log -n0 -rN`` should not return revisions beyond its merged revisions.
666
(#325618, #484109, Marius Kruger)
668
* ``bzr merge --weave`` and ``--lca`` will now create ``.BASE`` files for
669
files with conflicts (similar to ``--merge3``). The contents of the file
670
is a synthesis of all bases used for the merge.
671
(John Arbash Meinel, #40412)
673
* ``bzr mv --quiet`` really is quiet now. (Gordon Tyler, #271790)
675
* ``bzr serve`` is more clear about the risk of supplying --allow-writes.
676
(Robert Collins, #84659)
678
* ``bzr serve --quiet`` really is quiet now. (Gordon Tyler, #252834)
680
* Fix bug with redirected URLs over authenticated HTTP.
681
(Glen Mailer, Neil Martinsen-Burrell, Vincent Ladeuil, #395714)
683
* Interactive merge doesn't leave branch locks behind. (Aaron Bentley)
685
* Lots of bugfixes for the test suite on Windows. We should once again
686
have a test suite with no failures on Windows. (John Arbash Meinel)
688
* ``osutils.terminal_width()`` obeys the BZR_COLUMNS environment
689
variable but returns None if the terminal is not a tty (when output is
690
redirected for example). Also fixes its usage under OSes that doesn't
691
provide termios.TIOCGWINSZ. Make sure the corresponding tests runs on
693
(Joke de Buhr, Vincent Ladeuil, #353370, #62539)
694
(John Arbash Meinel, Vincent Ladeuil, #492561)
696
* Terminate ssh subprocesses when no references to them remain, fixing
697
subprocess and file descriptor leaks. (Andrew Bennetts, #426662)
699
* The ``--hardlink`` option of ``bzr branch`` and ``bzr checkout`` now
700
works for 2a format trees. Only files unaffected by content filters
701
will be hardlinked. (Andrew Bennetts, #408193)
703
* The new glob expansion on Windows would replace all ``\`` characters
704
with ``/`` even if it there wasn't a glob to expand, the arg was quoted,
705
etc. Now only change slashes if there is something being glob expanded.
706
(John Arbash Meinel, #485771)
708
* Use our faster ``KnownGraph.heads()`` functionality when computing the
709
new rich-root heads. This can cut a conversion time in half (mysql from
710
13.5h => 6.2h) (John Arbash Meinel, #487632)
712
* When launching a external diff tool via bzr diff --using, temporary files
713
are no longer created, rather, the path to the file in the working tree is
714
passed to the external diff tool. This allows the file to be edited if the
715
diff tool provides for this. (Gary van der Merwe, #490738)
717
* The launchpad-open command can now be used from a subdirectory of a
718
branch, not just from the root of the branch.
719
(Neil Martinsen-Burrell, #489102)
725
* ``bzr log`` is now faster. (Ian Clatworthy)
727
* ``bzr update`` provides feedback on which branch it is up to date with.
728
(Neil Martinsen-Burrell)
730
* ``bzr upgrade`` from pre-2a to 2a can be significantly faster (4x).
731
For details see the xml8 patch and heads() improvements.
734
* ``bzrlib.urlutils.local_path_from_url`` now accepts
735
'file://localhost/' as well as 'file:///' URLs on POSIX. (Michael
738
* The progress bar now shows only a spinner and per-operation counts,
739
not an overall progress bar. The previous bar was often not correlated
740
with real overall operation progress, either because the operations take
741
nonlinear time, or because at the start of the operation Bazaar couldn't
742
estimate how much work there was to do. (Martin Pool)
747
* Lots of documentation tweaks for inline help topics and command help
753
* ``bzrlib.textui`` (vestigial module) removed. (Martin Pool)
755
* The Launchpad plugin now has a function ``login`` which will log in to
756
Launchpad with launchpadlib, and ``load_branch`` which will return the
757
Launchpad Branch object corresponding to a given Bazaar Branch object.
763
* New test Feature: ``ModuleAvailableFeature``. It is designed to make it
764
easier to handle what tests you want to run based on what modules can be
765
imported. (Rather than lots of custom-implemented features that were
766
basically copy-and-pasted.) (John Arbash Meinel)
768
* ``osutils.timer_func()`` can be used to get either ``time.time()`` or
769
``time.clock()`` when you want to do performance timing.
770
``time.time()`` is limited to 15ms resolution on Windows, but
771
``time.clock()`` gives CPU and not wall-clock time on other platforms.
774
* Several code paths that were calling ``Transport.get().read()`` have
775
been changed to the equalivent ``Transport.get_bytes()``. The main
776
difference is that the latter will explicitly call ``file.close()``,
777
rather than expecting the garbage collector to handle it. This helps
778
with some race conditions on Windows during the test suite and sftp
779
tests. (John Arbash Meinel)
784
* TestCaseWithMemoryTransport no longer sets $HOME and $BZR_HOME to
785
unicode strings. (Michael Hudson, #464174)
791
:Codename: after sprint recovery
794
This release was pushed up from its normal release cycle due to a
795
regression in python 2.4 compatibility in 2.1.0b2. Since this regression
796
was caught before 2.1.0b2 was officially announced, the full changelog
797
includes both 2.1.0b3 and 2.1.0b2 changes.
799
Highlights of 2.1.0b3 are: new globbing code for all commands on Windows,
800
the test suite now conforms to python's trunk enhanced semantics (skip,
801
etc.), and ``bzr info -v`` will now report the correct branch and repo
802
formats for Remote objects.
808
* Users can define a shelve editor to provide shelf functionality at a
809
granularity finer than per-patch-hunk. (Aaron Bentley)
814
* Fix for shell completion and short options. (Benoît PIERRE)
816
* Fix ``bzr --profile-imports`` with Python 2.6. (Martin Pool)
818
* Hooks daughter classes should always call the base constructor.
819
(Alexander Belchenko, Vincent Ladeuil, #389648)
821
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
823
* On Windows, do glob expansion at the command-line level (as is usually
824
done in bash, etc.) This means that *all* commands get glob expansion
825
(bzr status, bzr add, bzr mv, etc). It uses a custom command line
826
parser, which allows us to know if a given section was quoted. It means
827
you can now do ``bzr ignore "*.py"``.
828
(John Arbash Meinel, #425510, #426410, #194450)
830
* Sanitize commit messages that come in from the '-m' flag. We translate
831
'\r\n' => '\n' and a plain '\r' => '\n'. The storage layer doesn't
832
allow those because XML store silently translate it anyway. (The parser
833
auto-translates \r\n => \n in ways that are hard for us to catch.)
835
* Show correct branch and repository format descriptions in
836
``bzr info -v`` on a smart server location. (Andrew Bennetts, #196080)
838
* The fix for bug #186920 accidentally broke compatibility with python
839
2.4. (Vincent Ladeuil, #475585)
841
* Using ``Repository.get_commit_builder().record_iter_changes()`` now
842
correctly sets ``self.inv_sha1`` to a sha1 string and
843
``self.new_inventory`` to an Inventory instance after calling
844
``self.finish_inventory()``. (Previously it accidently set both values
845
as a tuple on ``self.inv_sha1``. This was missed because
846
``repo.add_revision`` ignores the supplied inventory sha1 and recomputes
847
the sha1 from the repo directly. (John Arbash Meinel)
849
* Shelve command refuse to run if there is no real terminal.
850
(Alexander Belchenko)
852
* Avoid unnecessarily flushing of trace file; it's now unbuffered at the
853
Python level. (Martin Pool)
858
* Include Japanese translations for documentation (Inada Naoki)
860
* New API ``ui_factory.make_output_stream`` to be used for sending bulk
861
(rather than user-interaction) data to stdout. This automatically
862
coordinates with progress bars or other terminal activity, and can be
864
(Martin Pool, 493944)
869
* Some of the core groupcompress functionality now releases the GIL before
870
operation. Similar to how zlib and bz2 operate without the GIL in the
871
core compression and decompression routines. (John Arbash Meinel)
876
* -Dhpssvfs will now trigger on ``RemoteBzrDir._ensure_real``, providing
877
more debugging of VFS access triggers. (Robert Collins)
879
* KnownFailure is now signalled to ``ExtendedTestResult`` using the same
880
method that Python 2.7 uses - ``addExpectedFailure``. (Robert Collins)
882
* ``--parallel=fork`` is now compatible with --subunit.
883
(Robert Collins, Vincent Ladeuil, #419776)
885
* Reporting of failures shows test ids not descriptions and thus shows
886
parameterised tests correctly. (Robert Collins)
888
* TestNotApplicable is now handled within the TestCase.run method rather
889
than being looked for within ``ExtendedTestResult.addError``. This
890
provides better handling with other ``TestResult`` objects, degrading to
891
sucess rather than error. (Robert Collins)
893
* The private method ``_testConcluded`` on ``ExtendedTestResult`` has been
894
removed - it was empty and unused. (Robert Collins)
896
* UnavailableFeature is now handled within the TestCase.run method rather
897
than being looked for within addError. If the Result object does not
898
have an addNotSupported method, addSkip is attempted instead, and
899
failing that addSuccess. (Robert Collins)
901
* When a TestResult does not have an addSkip method, skipped tests are now
902
reported as successful tests, rather than as errors. This change is
903
to make it possible to get a clean test run with a less capable
904
TestResult. (Robert Collins)
911
:Codename: a load off my mind
914
This is our second feature-filled release since 2.0, pushing us down the
915
path to a 2.1.0. Once again, all bugfixes in 2.0.2 are present in 2.1.0b2.
917
Key highlights in this release are: improved handling of
918
failures-during-cleanup for commit, fixing a long-standing bug with
919
``bzr+http`` and shared repositories, all ``lp:`` urls to be resolved
920
behind proxies, and a new StaticTuple datatype, allowing us to reduce
921
memory consumption (50%) and garbage collector overhead (40% faster) for
924
* A new ``--concurrency`` option has been added as well as an associated
925
BZR_CONCURRENCY environment variable to specify the number of
926
processes that can be run concurrently when running ``bzr selftest``. The
927
command-line option overrides the environment variable if both are
928
specified. If none is specified. the number of processes is obtained
929
from the OS as before. (Matt Nordhoff, Vincent Ladeuil)
934
* ``bzr+http`` servers no longer give spurious jail break errors when
935
serving branches inside a shared repository. (Andrew Bennetts, #348308)
937
* Errors during commit are handled more robustly so that knock-on errors
938
are less likely to occur, and will not obscure the original error if
939
they do occur. This fixes some causes of ``TooManyConcurrentRequests``
940
and similar errors. (Andrew Bennetts, #429747, #243391)
942
* Launchpad urls can now be resolved from behind proxies.
943
(Gordon Tyler, Vincent Ladeuil, #186920)
945
* Reduce the strictness for StaticTuple, instead add a debug flag
946
``-Dstatic_tuple`` which will change apis to be strict and raise errors.
947
This way, most users won't see failures, but developers can improve
948
internals. (John Arbash Meinel, #471193)
950
* TreeTransform.adjust_path updates the limbo paths of descendants of adjusted
951
files. (Aaron Bentley)
953
* Unicode paths are now handled correctly and consistently by the smart
954
server. (Andrew Bennetts, Michael Hudson, #458762)
959
* When reading index files, we now use a ``StaticTuple`` rather than a
960
plain ``tuple`` object. This generally gives a 20% decrease in peak
961
memory, and can give a performance boost up to 40% on large projects.
964
* Peak memory under certain operations has been reduced significantly.
965
(eg, 'bzr branch launchpad standalone' is cut in half)
971
* Filtered views user documentation upgraded to refer to format 2a
972
instead of pre-2.0 formats. (Ian Clatworthy)
977
* Remove deprecated ``CLIUIFactory``. (Martin Pool)
979
* ``UIFactory`` now has new ``show_error``, ``show_message`` and
980
``show_warning`` methods, which can be hooked by non-text UIs.
986
* Added ``bzrlib._simple_set_pyx``. This is a hybrid between a Set and a
987
Dict (it only holds keys, but you can lookup the object located at a
988
given key). It has significantly reduced memory consumption versus the
989
builtin objects (1/2 the size of Set, 1/3rd the size of Dict). This is
990
used as the interning structure for StaticTuple objects.
993
* ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
994
the btree index parser and the chk map parser. This class functions
995
similarly to ``tuple`` objects. However, it can only point to a limited
996
collection of types. (Currently StaticTuple, str, unicode, None, bool,
997
int, long, float, but not subclasses). This allows us to remove it from
998
the garbage collector (it cannot be in a cycle), it also allows us to
999
intern the objects. In testing, this can reduce peak memory by 20-40%,
1000
and significantly improve performance by removing objects from being
1001
inspected by the garbage collector. (John Arbash Meinel)
1003
* ``GroupCompressBlock._ensure_content()`` will now release the
1004
``zlib.decompressobj()`` when the first request is for all of the
1005
content. (Previously it would only be released if you made a request for
1006
part of the content, and then all of it later.) This turns out to be a
1007
significant memory savings, as a ``zstream`` carries around approx 260kB
1008
of internal state and buffers. (For branching bzr.dev this drops peak
1009
memory from 382MB => 345MB.) (John Arbash Meinel)
1011
* When streaming content between ``2a`` format repositories, we now clear
1012
caches from earlier versioned files. (So 'revisions' is cleared when we
1013
start reading 'inventories', etc.) This can have a significant impact on
1014
peak memory for initial copies (~200MB). (John Arbash Meinel)
1020
:Codename: While the cat is away
1021
:2.1.0b1: 2009-10-14
1023
This is the first development release in the new split "stable" and
1024
"development" series. As such, the release is a snapshot of bzr.dev
1025
without creating a release candidate first. This release includes a
1026
fair amount of internal changes, with deprecated code being removed,
1027
and several new feature developments. People looking for a stable code
1028
base with only bugfixes should focus on the 2.0.1 release. All bugfixes
1029
present in 2.0.1 are present in 2.1.0b1.
1031
Highlights include support for ``bzr+ssh://host/~/homedir`` style urls,
1032
finer control over the plugin search path via extended BZR_PLUGIN_PATH
1033
syntax, visible warnings when extension modules fail to load, and improved
1034
error handling during unlocking.
1040
* Bazaar can now send mail through Apple OS X Mail.app.
1043
* ``bzr+ssh`` and ``bzr`` paths can now be relative to home directories
1044
specified in the URL. Paths starting with a path segment of ``~`` are
1045
relative to the home directory of the user running the server, and paths
1046
starting with ``~user`` are relative to the home directory of the named
1047
user. For example, for a user "bob" with a home directory of
1048
``/home/bob``, these URLs are all equivalent:
1050
* ``bzr+ssh://bob@host/~/repo``
1051
* ``bzr+ssh://bob@host/~bob/repo``
1052
* ``bzr+ssh://bob@host/home/bob/repo``
1054
If ``bzr serve`` was invoked with a ``--directory`` argument, then no
1055
home directories outside that directory will be accessible via this
1058
This is a feature of ``bzr serve``, so pre-2.1 clients will
1059
automatically benefit from this feature when ``bzr`` on the server is
1060
upgraded. (Andrew Bennetts, #109143)
1062
* Extensions can now be compiled if either Cython or Pyrex is available.
1063
Currently Pyrex is preferred, but that may change in the future.
1066
* Give more control on BZR_PLUGIN_PATH by providing a way to refer to or
1067
disable the user, site and core plugin directories.
1068
(Vincent Ladeuil, #412930, #316192, #145612)
1073
* Bazaar's native protocol code now correctly handles EINTR, which most
1074
noticeably occurs if you break in to the debugger while connected to a
1075
bzr+ssh server. You can now can continue from the debugger (by typing
1076
'c') and the process continues. However, note that pressing C-\ in the
1077
shell may still kill the SSH process, which is bug 162509, so you must
1078
sent a signal to the bzr process specifically, for example by typing
1079
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
1081
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
1082
filename will issue a warning and skip over those files.
1083
(Robert Collins, #3918)
1085
* ``bzr dpush`` now aborts if uncommitted changes (including pending merges)
1086
are present in the working tree. The configuration option ``dpush_strict``
1087
can be used to set the default for this behavior.
1088
(Vincent Ladeuil, #438158)
1090
* ``bzr merge`` and ``bzr remove-tree`` now requires --force if pending
1091
merges are present in the working tree.
1092
(Vincent Ladeuil, #426344)
1094
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
1095
traceback. (Martin Pool, #109115)
1097
* Don't give a warning on Windows when failing to import ``_readdir_pyx``
1098
as it is never built. (John Arbash Meinel, #430645)
1100
* Don't restrict the command name used to run the test suite.
1101
(Vincent Ladeuil, #419950)
1103
* ftp transports were built differently when the kerberos python module was
1104
present leading to obscure failures related to ASCII/BINARY modes.
1105
(Vincent Ladeuil, #443041)
1107
* Network streams now decode adjacent records of the same type into a
1108
single stream, reducing layering churn. (Robert Collins)
1110
* PreviewTree behaves correctly when get_file_mtime is invoked on an unmodified
1111
file. (Aaron Bentley, #251532)
1113
* Registry objects should not use iteritems() when asked to use items().
1114
(Vincent Ladeuil, #430510)
1116
* Weave based repositories couldn't be cloned when committers were using
1117
domains or user ids embedding '.sig'. Now they can.
1118
(Matthew Fuller, Vincent Ladeuil, #430868)
1123
* Revision specifiers can now be given in a more DWIM form, without
1124
needing explicit prefixes for specifiers like tags or revision id's.
1125
See ``bzr help revisionspec`` for full details. (Matthew Fuller)
1127
* Bazaar gives a warning before exiting, and writes into ``.bzr.log``, if
1128
compiled extensions can't be loaded. This typically indicates a
1129
packaging or installation problem. In this case Bazaar will keep
1130
running using pure-Python versions, but this may be substantially
1131
slower. The warning can be disabled by setting
1132
``ignore_missing_extensions = True`` in ``bazaar.conf``.
1133
See also <https://answers.launchpad.net/bzr/+faq/703>.
1134
(Martin Pool, #406113, #430529)
1136
* Secondary errors that occur during Branch.unlock and Repository.unlock
1137
no longer obscure the original error. These methods now use a new
1138
decorator, ``only_raises``. This fixes many causes of
1139
``TooManyConcurrentRequests`` and similar errors.
1140
(Andrew Bennetts, #429747)
1145
* Describe the new shell-like test feature. (Vincent Ladeuil)
1147
* Help on hooks no longer says 'Not deprecated' for hooks that are
1148
currently supported. (Ian Clatworthy, #422415)
1153
* ``bzrlib.user_encoding`` has been removed; use
1154
``bzrlib.osutils.get_user_encoding`` instead. (Martin Pool)
1156
* ``bzrlib.tests`` now uses ``stopTestRun`` for its ``TestResult``
1157
subclasses - the same as python's unittest module. (Robert Collins)
1159
* ``diff._get_trees_to_diff`` has been renamed to
1160
``diff.get_trees_and_branches_to_diff``. It is now a public API, and it
1161
returns the old and new branches. (Gary van der Merwe)
1163
* ``bzrlib.trace.log_error``, ``error`` and ``info`` have been deprecated.
1166
* ``MutableTree.has_changes()`` does not require a tree parameter anymore. It
1167
now defaults to comparing to the basis tree. It now checks for pending
1168
merges too. ``Merger.check_basis`` has been deprecated and replaced by the
1169
corresponding has_changes() calls. ``Merge.compare_basis``,
1170
``Merger.file_revisions`` and ``Merger.ensure_revision_trees`` have also
1172
(Vincent Ladeuil, #440631)
1174
* ``ProgressTask.note`` is deprecated.
1180
* Added ``-Drelock`` debug flag. It will ``note`` a message every time a
1181
repository or branch object is unlocked then relocked the same way.
1184
* ``BTreeLeafParser.extract_key`` has been tweaked slightly to reduce
1185
mallocs while parsing the index (approx 3=>1 mallocs per key read).
1186
This results in a 10% speedup while reading an index.
1187
(John Arbash Meinel)
1189
* The ``bzrlib.lsprof`` module has a new class ``BzrProfiler`` which makes
1190
profiling in some situations like callbacks and generators easier.
1196
* Passing ``--lsprof-tests -v`` to bzr selftest will cause lsprof output to
1197
be output for every test. Note that this is very verbose! (Robert Collins)
1199
* Setting ``BZR_TEST_PDB=1`` when running selftest will cause a pdb
1200
post_mortem to be triggered when a test failure occurs. (Robert Collins)
1202
* Shell-like tests can now be written. Code in ``bzrlib/tests/script.py`` ,
1203
documentation in ``developers/testing.txt`` for details.
1206
* Some tests could end up with the same id, that was dormant for
1208
(Vincent Ladeuil, #442980)

* Stop showing the number of tests due to missing features in the test
1211
progress bar. (Martin Pool)
1213
* Test parameterisation now does a shallow copy, not a deep copy of the test
1214
to be parameterised. This is not expected to break external use of test
1215
parameterisation, and is substantially faster. (Robert Collins)
1217
* Tests that try to open a bzr dir on an arbitrary transport will now
1218
fail unless they have explicitly permitted the transport via
1219
``self.permit_url``. The standard test factories such as ``self.get_url``
1220
will permit the urls they provide automatically, so only exceptional
1221
tests should need to do this. (Robert Collins)
1223
* The break-in test no longer cares about clean shutdown of the child,
1224
instead it is happy if the debugger starts up. (Robert Collins)
1226
* The full test suite is expected to pass when the C extensions are not
1227
present. (Vincent Ladeuil, #430749)
