:2.1.5: NOT RELEASED YET
43
The fourth release in our 2.1 series addresses some user-inconvenience bugs.
44
None are critical, but upgrading is recommended for all users on earlier 2.1
51
* Launchpad has announced that the ``edge.launchpad.net`` instance is
52
deprecated and may be shut down in the future
53
<http://blog.launchpad.net/general/edge-is-deprecated>. Bazaar has therefore
54
been updated in this release to talk to the main (``launchpad.net``) servers,
55
rather than the ``edge`` ones. (Vincent Ladeuil, #583667)
65
* Avoid UnicodeDecodeError in ``bzr add`` with multiple files under a non-ascii
66
path on windows from symlink support addition. (Martin [gz], #686611)
68
* Skip tests that needs a bzr source tree when there isn't one. This is
69
needed to succesfully run the test suite for installed versions.
70
(Vincent Ladeuil, #644855).
72
* Skip the tests that requires respecting the chmod bits when running as root.
73
(Vincent Ladeuil, #646133)
75
* Using bzr with `lp:` URLs behind an HTTP proxy should work.
76
(Robert Collins, #558343)
100
The third release in our 2.1 series addresses several user-inconvenience bugs
101
(and includes the fixes done in 2.0.6). None are critical, but upgrading is
102
recommended for all users on earlier 2.1 releases.
107
* Additional merges after an unrelated branch has been merged with its
108
history no longer crash when deleted files are involved.
109
(Vincent Ladeuil, John Arbash Meinel, #375898)
111
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
112
previously-unversioned directory within the tree: the directory is
113
marked versioned too.
114
(Martin Pool, #192859)
116
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
117
target of the symlink.
118
(Martin Pool, John Arbash Meinel, #128562)
120
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
121
permissions as ``.bzr`` directory on a POSIX OS.
122
(Parth Malwankar, #262450)
124
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
125
way which should help avoid problems with concurrent writers.
126
(Vincent Ladeuil, #525571)
128
* Don't traceback trying to unversion children files of an already
129
unversioned directory. (Vincent Ladeuil, #494221)
131
* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
132
contains only NUL bytes). Instead warn the user, and allow ``bzr
133
break-lock`` to remove it. (Andrew Bennetts, #619872)
135
* Fix ``AttributeError on parent.children`` when adding a file under a
136
directory that was a symlink in the previous commit.
137
(Martin Pool, #192859)
139
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
140
which can result in "missing referenced chk root keys" errors when
141
fetching from repositories with affected revisions.
142
(Andrew Bennetts, #522637)
144
* Raise ValueError instead of a string exception.
145
(John Arbash Meinel, #586926)
147
* Reduce peak memory by one copy of compressed text.
148
(John Arbash Meinel, #566940)
150
* Repositories accessed via a smart server now reject being stacked on a
151
repository in an incompatible format, as is the case when accessing them
152
via other methods. This was causing fetches from those repositories via
153
a smart server (e.g. using ``bzr branch``) to receive invalid data.
154
(Andrew Bennetts, #562380)
156
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
157
error. This error was caused by 2.0 not being updated when upstream
158
python merged the end of run patch, which chose ``stopTestRun`` rather than
159
``done``. (Robert Collins, #571437)
161
* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``
162
being thrown from ``xml_serializer`` on certain cElementTree setups.
163
(Martin [gz], #254278)
165
* When passing a file to ``UTF8DirReader`` make sure to close the current
166
directory file handle after the chdir fails. Otherwise when passing many
167
filenames into a command line ``bzr status`` we would leak descriptors.
168
(John Arbash Meinel, #583486)
173
* ``build_tree_contents`` can create symlinks.
174
(Martin Pool, John Arbash Meinel)
182
This release fixes two critical networking issues with older servers and
183
with interrupted system call errors when pushing or pulling. We recommend
184
upgrading to anyone running a 2.1.x version of bzr.
189
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
190
support of bzr-externals and scmproj plugins.
191
(Alexander Belchenko, bug #572098)
193
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
194
(Aaron Bentley, #559436)
196
* Do not register a SIGWINCH signal handler, instead just poll for the
197
terminal width as needed. This avoids the "Interrupted System Call"
198
problems that occur on POSIX with all currently released versions of
200
(Andrew Bennetts, #583941)
202
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
204
(Andrew Bennetts, #528041)
206
* Reset ``siginterrupt`` flag to False every time we handle a signal
207
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
208
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
209
errors compared to registering ``signal.signal`` directly.
212
* Reduce peak memory by one copy of compressed text.
213
(John Arbash Meinel, #566940)
215
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
216
(John Arbash Meinel, #582656)
218
* When passing a file to ``UTF8DirReader`` make sure to close the current
219
directory file handle after the chdir fails. Otherwise when passing many
220
filenames into a command line ``bzr status`` we would leak descriptors.
221
(John Arbash Meinel, #583486)
226
* ``_remember_remote_is_before`` no longer raises AssertionError when
227
suboptimal network behaviour is noticed; instead it just mutters to the
228
log file (and warns the user if they have set the ``hpss`` debug flag).
229
This was causing unnecessary aborts for performance bugs that are minor
231
(Andrew Bennetts, #528041)
239
This is a small bugfix release. Upgrading is recommended for anyone
240
running 2.1.0 or earlier.
245
* Allow syscalls to automatically restart when ``TextUIFactory``'s
246
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
247
IO, which are often poorly handled by Python's libraries and parts of
248
bzrlib. (Andrew Bennetts, #496813)
250
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
251
(Martin Pool, #331095)
253
* Fix plugin packaging on Windows. (Ian Clatworthy, #524162)
255
* Fix stub SFTP test server to call os.getcwdu().
256
(Vincent Ladeuil, #526221, #526353)
258
* Fixed CHM generation by moving the NEWS section template into
259
a separate file. (Ian Clatworthy, #524184)
261
* Merge correctly when this_tree is not a WorkingTree. (Aaron Bentley)
263
* Register SIGWINCH handler only when creating a ``TextUIFactory``; avoids
264
problems importing bzrlib from a non-main thread.
265
(Elliot Murphy, #521989)
267
* Repositories accessed via a smart server now reject being stacked on a
268
repository in an incompatible format, as is the case when accessing them
269
via other methods. This was causing fetches from those repositories via
270
a smart server (e.g. using ``bzr branch``) to receive invalid data.
271
(Andrew Bennetts, #562380)
273
* Standardize the error handling when creating a new ``StaticTuple``
274
(problems will raise TypeError). (Matt Nordhoff, #457979)
276
* Warn if pyrex is too old to compile the new ``SimpleSet`` and
277
``StaticTuple`` extensions, rather than having the build fail randomly.
278
(John Arbash Meinel, #449776)
283
* Added a link to the Desktop Guide. (Ian Clatworthy)
285
* Added What's New in Bazaar 2.1 document. (Ian Clatworthy)
287
* Drop Google Analytics from the core docs as they caused problems
288
in the CHM files. (Ian Clatworthy, #502010)
293
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
294
can set a signal handler and call ``signal.siginterrupt(signum,
295
False)`` for it, if the platform and Python version supports it.
296
(Andrew Bennetts, #496813)
302
:Codename: Strasbourg
305
This release marks our second long-term-stable series. The Bazaar team
306
has decided that we will continue to make bugfix-only 2.0.x and 2.1.x
307
releases, along with 2.2 development releases.
309
This is a fairly incremental update, focusing on polish and bugfixing.
310
There are no changes for supported disk formats. Key updates include
311
reduced memory consumption for many operations, a new per-file merge
312
hook, ignore patterns can now include '!' to exclude files, globbing
313
support for all commands on Windows, and support for addressing home
314
directories via ``bzr+ssh://host/~/`` syntax.
316
Users are encouraged to upgrade from the 2.0 stable series.
321
* Don't require testtools to use SFTP.
322
(Vincent Ladeuil, #516183)
324
* Fix "AttributeError in Inter1and2Helper" during fetch.
325
(Martin Pool, #513432)
327
* ``bzr update`` performs the two merges in a more logical order and will stop
328
when it encounters conflicts.
329
(Gerard Krol, #113809)
331
* Give a better error message when doing ``bzr bind`` in an already bound
332
branch. (Neil Martinsen-Burrell, #513063)
334
* Ignore ``KeyError`` from ``remove_index`` during ``_abort_write_group``
335
in a pack repository, which can happen harmlessly if the abort occurs during
336
finishing the write group. Also use ``bzrlib.cleanup`` so that any
337
other errors that occur while aborting the individual packs won't be
338
hidden by secondary failures when removing the corresponding indices.
339
(Andrew Bennetts, #423015)
341
* Set the mtime of files exported to a directory by ``bzr export`` all to
342
the same value to avoid confusing ``make`` and other date-based build
343
systems. (Robert Collins, #515631)
348
* Fetching into experimental formats will now print a warning. (Jelmer
354
* ``Repository.deserialise_inventory`` has been renamed to
355
``Repository._deserialise_inventory`` to indicate it is private.
358
* ``Repository.get_inventory_xml`` has been renamed to
359
``Repository._get_inventory_xml`` to indicate it is private.
362
* ``Repository.serialise_inventory`` has been renamed to
363
``Repository._serialise_inventory`` to indicate it is private.
365
* Using the ``bzrlib.chk_map`` module from within multiple threads at the
366
same time was broken due to race conditions with a module level page
367
cache. This shows up as a KeyError in the ``bzrlib.lru_cache`` code with
368
``bzrlib.chk_map`` in the backtrace, and can be triggered without using
369
the same high level objects such as ``bzrlib.repository.Repository``
370
from different threads. chk_map now uses a thread local cache which may
371
increase memory pressure on processes using threads.
372
(Robert Collins, John Arbash Meinel, #514090)
374
* The new ``merge_file_content`` should now be ok with tests to avoid
376
(Vincent Ladeuil, #515597)
381
* Use ``bzrlib.cleanup`` rather than less robust ``try``/``finally``
382
blocks in several places in ``bzrlib.merge``. This avoids masking prior
383
errors when errors like ``ImmortalPendingDeletion`` occur during cleanup
385
(Andrew Bennetts, #517275)
390
* The ``remove_index`` method of
391
``bzrlib.repofmt.pack_repo.AggregateIndex`` no longer takes a ``pack``
392
argument. This argument was always ignored.
393
(Andrew Bennetts, #423015)
398
:Codename: after the bubbles
399
:2.1.0rc2: 2010-01-29
401
This is a quick-turn-around to update a small issue with our new per-file
402
merge hook. We expect no major changes from this to the final 2.1.0.
407
* The new ``merge_file_content`` hook point has been altered to provide a
408
better API where state for extensions can be stored rather than the
409
too-simple function based approach. This fixes a performance regression
410
where branch configuration would be parsed per-file during merge. As
411
part of this the included news_merger has been refactored into a base
412
helper class ``bzrlib.merge.ConfigurableFileMerger``.
413
(Robert Collins, John Arbash Meinel, #513822)
419
:Codename: the 'new' stable
420
:2.1.0rc1: 2009-01-21
422
This is the first stable release candidate for Bazaar's 2.1 series. From
423
this point onwards, the 2.1 series will be considered stable (as the 2.0
424
series) and only bugfixes are expected to be incorporated. The dozen or so
425
bugfixes in the 2.0.4 release are also included in this release (along
426
with more than 15 more bugfixes). Some of the interesting features are
427
support for per-file merge hooks, ``bzr unshelve --preview``, support
428
for using ! in ignore files to exclude files from being ignored, a small
429
memory leak was squashed, and many ``ObjectNotLocked`` errors were fixed.
430
This looks to be a very good start for a new stable series.
436
* Add bug information to log output when available.
437
(Neil Martinsen-Burrell, Guillermo Gonzalez, #251729)
439
* Added ``merge_file_content`` hook point to ``Merger``, allowing plugins
440
to register custom merge logic, e.g. to provide smarter merging for
443
* Bazaar now includes the ``news_merge`` plugin. It is disabled by
444
default, to enable it add a ``news_merge_files`` option to your
445
configuration. Consult ``bzr help news_merge`` for more information.
448
* ``bzr branch`` now takes a ``--bind`` option. This lets you
449
branch and bind all in one command. (Ian Clatworthy)
451
* ``bzr switch`` now takes a ``--revision`` option, to allow switching to
452
a specific revision of a branch. (Daniel Watkins, #183559)
454
* ``bzr unshelve --preview`` can now be used to show how a patch on the
455
shelf would be applied to the working tree.
456
(Guilherme Salgado, #308122)
458
* ``bzr update`` now takes a ``--revision`` argument. This lets you
459
change the revision of the working tree to any revision in the
460
ancestry of the current or master branch. (Matthieu Moy, Mark Hammond,
463
* ``-Dbytes`` can now be used to display the total number of bytes
464
transferred for the current command. This information is always logged
465
to ``.bzr.log`` for later inspection. (John Arbash Meinel)
467
* New ignore patterns. Patterns prefixed with '!' are exceptions to
468
ignore patterns and take precedence over regular ignores. Such
469
exceptions are used to specify files that should be versioned which
470
would otherwise be ignored. Patterns prefixed with '!!' act as regular
471
ignore patterns, but have highest precedence, even over the '!'
472
exception patterns. (John Whitley, #428031)
474
* The ``supress_warnings`` configuration option has been introduced to disable
475
various warnings (it currently only supports the ``format_deprecation``
476
warning). The new option can be set in any of the following locations:
477
``bazaar.conf``, ``locations.conf`` and/or ``branch.conf``.
478
(Ted Gould, Matthew Fuller, Vincent Ladeuil)
483
* Always show a message if an OS error occurs while trying to run a
484
user-specified commit message editor.
485
(Martin Pool, #504842)
487
* ``bzr diff`` will now use the epoch when it is unable to determine
488
the timestamp of a file, if the revision it was introduced in is a
489
ghost. (Jelmer Vernooij, #295611)
491
* ``bzr switch -b`` can now create branches that are located using directory
492
services such as ``lp:``, even when the branch name doesn't contain a
493
'/'. (Neil Martinsen-Burrell, #495263)
495
* ``bzr unshelve`` has improved messages about what it is doing.
496
(Neil Martinsen-Burrell, #496917)
498
* Concurrent autopacking is more resilient to already-renamed pack files.
499
If we find that a file we are about to obsolete is already obsoleted, we
500
do not try to rename it, and we leave the file in ``obsolete_packs``.
501
The code is also fault tolerant if a file goes missing, assuming that
502
another process already removed the file.
503
(John Arbash Meinel, Gareth White, #507557)
505
* Fix "Too many concurrent requests" in reconcile when network connection
506
fails. (Andrew Bennetts, #503878)
508
* Fixed a side effect mutation of ``RemoteBzrDirFormat._network_name``
509
that caused some tests to fail when run in a non-default order.
510
Probably no user impact. (Martin Pool, #504102)
512
* Fixed ``ObjectNotLocked`` error in ``bzr cat -rbranch:../foo FILE``.
513
(Andrew Bennetts, #506274)
515
* FTP transports support Unicode paths by encoding/decoding them as utf8.
516
(Vincent Ladeuil, #472161)
518
* Listen to the SIGWINCH signal to update the terminal width.
519
(Vincent Ladeuil, #316357)
521
* Progress bars are now hidden when ``--quiet`` is given.
522
(Martin Pool, #320035)
524
* ``SilentUIFactory`` now supports ``make_output_stream`` and discards
525
whatever is written to it. This un-breaks some plugin tests that
526
depended on this behaviour.
527
(Martin Pool, #499757)
529
* When operations update the working tree, all affected files should end
530
up with the same mtime. (eg. when versioning a generated file, if you
531
update the source and the generated file together, the generated file
532
should appear up-to-date.)
533
(John Arbash Meinel, Martin <gzlist>, #488724)
538
* Added ``add_cleanup`` and ``cleanup_now`` to ``bzrlib.command.Command``.
539
All the builtin commands now use ``add_cleanup`` rather than
540
``try``/``finally`` blocks where applicable as it is simpler and more
541
robust. (Andrew Bennetts)
543
* All except a small number of storage formats are now hidden, making
544
the help for numerous commands far more digestible. (Ian Clatworthy)
546
* Attempts to open a shared repository as a branch (e.g. ``bzr branch
547
path/to/repo``) will now include "location is a repository" as a hint in
548
the error message. (Brian de Alwis, Andrew Bennetts, #440952)
550
* Push will now inform the user when they are trying to push to a foreign
551
VCS for which roundtripping is not supported, and will suggest them to
552
use dpush. (Jelmer Vernooij)
554
* The version of bzr being run is now written to the log file.
557
* Transport network activity indicator is shown more of the time when
558
Bazaar is doing network IO.
564
* Add documentation on creating merges with more than one parent.
565
(Neil Martinsen-Burrell, #481526)
567
* Better explain the --uncommitted option of merge.
568
(Neil Martinsen-Burrell, #505088)
570
* Improve discussion of pending merges in the documentation for
571
``revert``. (Neil Martinsen-Burrell, #505093)
573
* Improved help for ``bzr send``.
574
(Martin Pool, Bojan Nikolic)
576
* There is a System Administrator's Guide in ``doc/en/admin-guide``,
577
including discussions of installation, relevant plugins, security and
578
backup. (Neil Martinsen-Burrell)
580
* The ``conflicts`` help topic has been renamed to ``conflict-types``.
583
* The User Reference is now presented as a series of topics.
584
Many of the included topics have link and format tweaks applied.
590
* Added ``cachedproperty`` decorator to ``bzrlib.decorators``.
593
* Many test features were renamed from ``FooFeature`` to ``foo_feature``
594
to be consistent with instances being lower case and classes being
595
CamelCase. For the features that were more likely to be used, we added a
596
deprecation thunk, but not all. (John Arbash Meinel)
598
* Merger classes (such as ``Merge3Merger``) now expect a ``this_branch``
599
parameter in their constructors, and provide ``this_branch`` as an
600
attribute. (Andrew Bennetts)
602
* The Branch hooks pre_change_branch_tip no longer masks exceptions raised
603
by plugins - the original exceptions are now preserved. (Robert Collins)
605
* The Transport ``Server.tearDown`` method is now renamed to
606
``stop_server`` and ``setUp`` to ``start_server`` for consistency with
607
our normal naming pattern, and to avoid confusion with Python's
608
``TestCase.tearDown``. (Martin Pool)
610
* ``WorkingTree.update`` implementations must now accept a ``revision``
616
* Added ``BzrDir.open_branchV3`` smart server request, which can receive
617
a string of details (such as "location is a repository") as part of a
618
``nobranch`` response. (Andrew Bennetts, #440952)
620
* New helper osutils.UnicodeOrBytesToBytesWriter which encodes unicode
621
objects but passes str objects straight through. This is used for
622
selftest but may be useful for diff and other operations that generate
623
mixed output. (Robert Collins)
625
* New exception ``NoRoundtrippingSupport``, for use by foreign branch
626
plugins. (Jelmer Vernooij)
631
* ``bzrlib.tests.permute_for_extension`` is a helper that simplifies
632
running all tests in the current module, once against a pure python
633
implementation, and once against an extension (pyrex/C) implementation.
634
It can be used to dramatically simplify the implementation of
635
``load_tests``. (John Arbash Meinel)
637
* ``bzrlib.tests.TestCase`` now subclasses ``testtools.testcase.TestCase``.
638
This permits features in testtools such as getUniqueInteger and
639
getUniqueString to be used. Because of this, testtools version 0.9.2 or
640
newer is now a dependency to run bzr selftest. Running with versions of
641
testtools less than 0.9.2 will cause bzr to error while loading the test
642
suite. (Robert Collins)
644
* Shell-like tests now support the command "mv" for moving files. The
645
syntax for ``mv file1 file2``, ``mv dir1 dir2`` and ``mv file dir`` is
646
supported. (Neil Martinsen-Burrell)
648
* The test progress bar no longer distinguishes tests that 'errored' from
649
tests that 'failed' - they're all just failures.

659
The fourth beta release in the 2.1 series brings with it a significant
660
number of bugfixes (~20). The test suite is once again (finally) "green"
661
on Windows, and should remain that way for future releases. There are a
662
few performance related updates (faster upgrade and log), and several UI
663
tweaks. There has also been a significant number of tweaks to the runtime
664
documentation. 2.1.0b4 include everything from the 2.0.3 release.
670
* The BZR_SSH environmental variable may now be set to the path of a secure
671
shell client. If currently set to the value ``ssh`` it will now guess the
672
vendor of the program with that name, to restore the old behaviour that
673
indicated the SSH Corporation client use ``sshcorp`` instead as the magic
674
string. (Martin <gzlist@googlemail.com>, #176292)
679
* ``bzr commit`` now has a ``--commit-time`` option.
680
(Alexander Sack, #459276)
682
* ``-Dhpss`` now increases logging done when run on the bzr server,
683
similarly to how it works on the client. (John Arbash Meinel)
685
* New option ``bzr unshelve --keep`` applies the changes and leaves them
686
on the shelf. (Martin Pool, Oscar Fuentes, #492091)
688
* The ``BZR_COLUMNS`` envrionment variable can be set to force bzr to
689
respect a given terminal width. This can be useful when output is
690
redirected or in obscure cases where the default value is not
691
appropriate. Pagers can use it to get a better control of the line
695
* The new command ``bzr lp-mirror`` will request that Launchpad update its
696
mirror of a local branch. This command will only function if launchpadlib
704
* After renaming a file, the dirstate could accidentally reference
705
``source\\path`` rather than ``source/path`` on Windows. This might be a
706
source of some dirstate-related failures. (John Arbash Meinel)
708
* ``bzr commit`` now detects commit messages that looks like file names
709
and issues a warning.
710
(Gioele Barabucci, #73073)
712
* ``bzr ignore /`` no longer causes an IndexError. (Gorden Tyler, #456036)
714
* ``bzr log -n0 -rN`` should not return revisions beyond its merged revisions.
715
(#325618, #484109, Marius Kruger)
717
* ``bzr merge --weave`` and ``--lca`` will now create ``.BASE`` files for
718
files with conflicts (similar to ``--merge3``). The contents of the file
719
is a synthesis of all bases used for the merge.
720
(John Arbash Meinel, #40412)
722
* ``bzr mv --quiet`` really is quiet now. (Gordon Tyler, #271790)
724
* ``bzr serve`` is more clear about the risk of supplying --allow-writes.
725
(Robert Collins, #84659)
727
* ``bzr serve --quiet`` really is quiet now. (Gordon Tyler, #252834)
729
* Fix bug with redirected URLs over authenticated HTTP.
730
(Glen Mailer, Neil Martinsen-Burrell, Vincent Ladeuil, #395714)
732
* Interactive merge doesn't leave branch locks behind. (Aaron Bentley)
734
* Lots of bugfixes for the test suite on Windows. We should once again
735
have a test suite with no failures on Windows. (John Arbash Meinel)
737
* ``osutils.terminal_width()`` obeys the BZR_COLUMNS environment
738
variable but returns None if the terminal is not a tty (when output is
739
redirected for example). Also fixes its usage under OSes that doesn't
740
provide termios.TIOCGWINSZ. Make sure the corresponding tests runs on
742
(Joke de Buhr, Vincent Ladeuil, #353370, #62539)
743
(John Arbash Meinel, Vincent Ladeuil, #492561)
745
* Terminate SSH subprocesses when no references to them remain, fixing
746
subprocess and file descriptor leaks. (Andrew Bennetts, #426662)
748
* The ``--hardlink`` option of ``bzr branch`` and ``bzr checkout`` now
749
works for 2a format trees. Only files unaffected by content filters
750
will be hardlinked. (Andrew Bennetts, #408193)
752
* The new glob expansion on Windows would replace all ``\`` characters
753
with ``/`` even if it there wasn't a glob to expand, the arg was quoted,
754
etc. Now only change slashes if there is something being glob expanded.
755
(John Arbash Meinel, #485771)
757
* Use our faster ``KnownGraph.heads()`` functionality when computing the
758
new rich-root heads. This can cut a conversion time in half (mysql from
759
13.5h => 6.2h) (John Arbash Meinel, #487632)
761
* When launching a external diff tool via bzr diff --using, temporary files
762
are no longer created, rather, the path to the file in the working tree is
763
passed to the external diff tool. This allows the file to be edited if the
764
diff tool provides for this. (Gary van der Merwe, #490738)
766
* The launchpad-open command can now be used from a subdirectory of a
767
branch, not just from the root of the branch.
768
(Neil Martinsen-Burrell, #489102)
774
* ``bzr log`` is now faster. (Ian Clatworthy)
776
* ``bzr update`` provides feedback on which branch it is up to date with.
777
(Neil Martinsen-Burrell)
779
* ``bzr upgrade`` from pre-2a to 2a can be significantly faster (4x).
780
For details see the xml8 patch and heads() improvements.
783
* ``bzrlib.urlutils.local_path_from_url`` now accepts
784
'file://localhost/' as well as 'file:///' URLs on POSIX. (Michael
787
* The progress bar now shows only a spinner and per-operation counts,
788
not an overall progress bar. The previous bar was often not correlated
789
with real overall operation progress, either because the operations take
790
nonlinear time, or because at the start of the operation Bazaar couldn't
791
estimate how much work there was to do. (Martin Pool)
796
* Lots of documentation tweaks for inline help topics and command help
802
* ``bzrlib.textui`` (vestigial module) removed. (Martin Pool)
804
* The Launchpad plugin now has a function ``login`` which will log in to
805
Launchpad with launchpadlib, and ``load_branch`` which will return the
806
Launchpad Branch object corresponding to a given Bazaar Branch object.
812
* New test Feature: ``ModuleAvailableFeature``. It is designed to make it
813
easier to handle what tests you want to run based on what modules can be
814
imported. (Rather than lots of custom-implemented features that were
815
basically copy-and-pasted.) (John Arbash Meinel)
817
* ``osutils.timer_func()`` can be used to get either ``time.time()`` or
818
``time.clock()`` when you want to do performance timing.
819
``time.time()`` is limited to 15ms resolution on Windows, but
820
``time.clock()`` gives CPU and not wall-clock time on other platforms.
823
* Several code paths that were calling ``Transport.get().read()`` have
824
been changed to the equalivent ``Transport.get_bytes()``. The main
825
difference is that the latter will explicitly call ``file.close()``,
826
rather than expecting the garbage collector to handle it. This helps
827
with some race conditions on Windows during the test suite and SFTP
828
tests. (John Arbash Meinel)
833
* TestCaseWithMemoryTransport no longer sets $HOME and $BZR_HOME to
834
unicode strings. (Michael Hudson, #464174)
840
:Codename: after sprint recovery
843
This release was pushed up from its normal release cycle due to a
844
regression in python 2.4 compatibility in 2.1.0b2. Since this regression
845
was caught before 2.1.0b2 was officially announced, the full changelog
846
includes both 2.1.0b3 and 2.1.0b2 changes.
848
Highlights of 2.1.0b3 are: new globbing code for all commands on Windows,
849
the test suite now conforms to python's trunk enhanced semantics (skip,
850
etc.), and ``bzr info -v`` will now report the correct branch and repo
851
formats for Remote objects.
857
* Users can define a shelve editor to provide shelf functionality at a
858
granularity finer than per-patch-hunk. (Aaron Bentley)
863
* Fix for shell completion and short options. (Benoît PIERRE)
865
* Fix ``bzr --profile-imports`` with Python 2.6. (Martin Pool)
867
* Hooks daughter classes should always call the base constructor.
868
(Alexander Belchenko, Vincent Ladeuil, #389648)
870
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
872
* On Windows, do glob expansion at the command-line level (as is usually
873
done in bash, etc.) This means that *all* commands get glob expansion
874
(bzr status, bzr add, bzr mv, etc). It uses a custom command line
875
parser, which allows us to know if a given section was quoted. It means
876
you can now do ``bzr ignore "*.py"``.
877
(John Arbash Meinel, #425510, #426410, #194450)
879
* Sanitize commit messages that come in from the '-m' flag. We translate
880
'\r\n' => '\n' and a plain '\r' => '\n'. The storage layer doesn't
881
allow those because XML store silently translate it anyway. (The parser
882
auto-translates \r\n => \n in ways that are hard for us to catch.)
884
* Show correct branch and repository format descriptions in
885
``bzr info -v`` on a smart server location. (Andrew Bennetts, #196080)
887
* The fix for bug #186920 accidentally broke compatibility with python
888
2.4. (Vincent Ladeuil, #475585)
890
* Using ``Repository.get_commit_builder().record_iter_changes()`` now
891
correctly sets ``self.inv_sha1`` to a sha1 string and
892
``self.new_inventory`` to an Inventory instance after calling
893
``self.finish_inventory()``. (Previously it accidently set both values
894
as a tuple on ``self.inv_sha1``. This was missed because
895
``repo.add_revision`` ignores the supplied inventory sha1 and recomputes
896
the sha1 from the repo directly. (John Arbash Meinel)
898
* Shelve command refuse to run if there is no real terminal.
899
(Alexander Belchenko)
901
* Avoid unnecessarily flushing of trace file; it's now unbuffered at the
902
Python level. (Martin Pool)
907
* Include Japanese translations for documentation (Inada Naoki)
909
* New API ``ui_factory.make_output_stream`` to be used for sending bulk
910
(rather than user-interaction) data to stdout. This automatically
911
coordinates with progress bars or other terminal activity, and can be
913
(Martin Pool, 493944)
918
* Some of the core groupcompress functionality now releases the GIL before
919
operation. Similar to how zlib and bz2 operate without the GIL in the
920
core compression and decompression routines. (John Arbash Meinel)
925
* -Dhpssvfs will now trigger on ``RemoteBzrDir._ensure_real``, providing
926
more debugging of VFS access triggers. (Robert Collins)
928
* KnownFailure is now signalled to ``ExtendedTestResult`` using the same
929
method that Python 2.7 uses - ``addExpectedFailure``. (Robert Collins)
931
* ``--parallel=fork`` is now compatible with --subunit.
932
(Robert Collins, Vincent Ladeuil, #419776)
934
* Reporting of failures shows test ids not descriptions and thus shows
935
parameterised tests correctly. (Robert Collins)
937
* TestNotApplicable is now handled within the TestCase.run method rather
938
than being looked for within ``ExtendedTestResult.addError``. This
939
provides better handling with other ``TestResult`` objects, degrading to
940
sucess rather than error. (Robert Collins)
942
* The private method ``_testConcluded`` on ``ExtendedTestResult`` has been
943
removed - it was empty and unused. (Robert Collins)
945
* UnavailableFeature is now handled within the TestCase.run method rather
946
than being looked for within addError. If the Result object does not
947
have an addNotSupported method, addSkip is attempted instead, and
948
failing that addSuccess. (Robert Collins)
950
* When a TestResult does not have an addSkip method, skipped tests are now
951
reported as successful tests, rather than as errors. This change is
952
to make it possible to get a clean test run with a less capable
953
TestResult. (Robert Collins)
960
:Codename: a load off my mind
963
This is our second feature-filled release since 2.0, pushing us down the
964
path to a 2.1.0. Once again, all bugfixes in 2.0.2 are present in 2.1.0b2.
966
Key highlights in this release are: improved handling of
967
failures-during-cleanup for commit, fixing a long-standing bug with
968
``bzr+http`` and shared repositories, all ``lp:`` URLs to be resolved
969
behind proxies, and a new StaticTuple datatype, allowing us to reduce
970
memory consumption (50%) and garbage collector overhead (40% faster) for
973
* A new ``--concurrency`` option has been added as well as an associated
974
BZR_CONCURRENCY environment variable to specify the number of
975
processes that can be run concurrently when running ``bzr selftest``. The
976
command-line option overrides the environment variable if both are
977
specified. If none is specified. the number of processes is obtained
978
from the OS as before. (Matt Nordhoff, Vincent Ladeuil)
983
* ``bzr+http`` servers no longer give spurious jail break errors when
984
serving branches inside a shared repository. (Andrew Bennetts, #348308)
986
* Errors during commit are handled more robustly so that knock-on errors
987
are less likely to occur, and will not obscure the original error if
988
they do occur. This fixes some causes of ``TooManyConcurrentRequests``
989
and similar errors. (Andrew Bennetts, #429747, #243391)
991
* Launchpad URLs can now be resolved from behind proxies.
992
(Gordon Tyler, Vincent Ladeuil, #186920)
994
* Reduce the strictness for StaticTuple, instead add a debug flag
995
``-Dstatic_tuple`` which will change apis to be strict and raise errors.
996
This way, most users won't see failures, but developers can improve
997
internals. (John Arbash Meinel, #471193)
999
* TreeTransform.adjust_path updates the limbo paths of descendants of adjusted
1000
files. (Aaron Bentley)
1002
* Unicode paths are now handled correctly and consistently by the smart
1003
server. (Andrew Bennetts, Michael Hudson, #458762)
1008
* When reading index files, we now use a ``StaticTuple`` rather than a
1009
plain ``tuple`` object. This generally gives a 20% decrease in peak
1010
memory, and can give a performance boost up to 40% on large projects.
1011
(John Arbash Meinel)
1013
* Peak memory under certain operations has been reduced significantly.
1014
(eg, 'bzr branch launchpad standalone' is cut in half)
1015
(John Arbash Meinel)
1020
* Filtered views user documentation upgraded to refer to format 2a
1021
instead of pre-2.0 formats. (Ian Clatworthy)
1026
* Remove deprecated ``CLIUIFactory``. (Martin Pool)
1028
* ``UIFactory`` now has new ``show_error``, ``show_message`` and
1029
``show_warning`` methods, which can be hooked by non-text UIs.
1035
* Added ``bzrlib._simple_set_pyx``. This is a hybrid between a Set and a
1036
Dict (it only holds keys, but you can lookup the object located at a
1037
given key). It has significantly reduced memory consumption versus the
1038
builtin objects (1/2 the size of Set, 1/3rd the size of Dict). This is
1039
used as the interning structure for StaticTuple objects.
1040
(John Arbash Meinel)
1042
* ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
1043
the btree index parser and the chk map parser. This class functions
1044
similarly to ``tuple`` objects. However, it can only point to a limited
1045
collection of types. (Currently StaticTuple, str, unicode, None, bool,
1046
int, long, float, but not subclasses). This allows us to remove it from
1047
the garbage collector (it cannot be in a cycle), it also allows us to
1048
intern the objects. In testing, this can reduce peak memory by 20-40%,
1049
and significantly improve performance by removing objects from being
1050
inspected by the garbage collector. (John Arbash Meinel)
1052
* ``GroupCompressBlock._ensure_content()`` will now release the
1053
``zlib.decompressobj()`` when the first request is for all of the
1054
content. (Previously it would only be released if you made a request for
1055
part of the content, and then all of it later.) This turns out to be a
1056
significant memory savings, as a ``zstream`` carries around approx 260kB
1057
of internal state and buffers. (For branching bzr.dev this drops peak
1058
memory from 382MB => 345MB.) (John Arbash Meinel)
1060
* When streaming content between ``2a`` format repositories, we now clear
1061
caches from earlier versioned files. (So 'revisions' is cleared when we
1062
start reading 'inventories', etc.) This can have a significant impact on
1063
peak memory for initial copies (~200MB). (John Arbash Meinel)
1069
:Codename: While the cat is away
1070
:2.1.0b1: 2009-10-14
1072
This is the first development release in the new split "stable" and
1073
"development" series. As such, the release is a snapshot of bzr.dev
1074
without creating a release candidate first. This release includes a
1075
fair amount of internal changes, with deprecated code being removed,
1076
and several new feature developments. People looking for a stable code
1077
base with only bugfixes should focus on the 2.0.1 release. All bugfixes
1078
present in 2.0.1 are present in 2.1.0b1.
1080
Highlights include support for ``bzr+ssh://host/~/homedir`` style URLs,
1081
finer control over the plugin search path via extended BZR_PLUGIN_PATH
1082
syntax, visible warnings when extension modules fail to load, and improved
1083
error handling during unlocking.
1089
* Bazaar can now send mail through Apple OS X Mail.app.
1092
* ``bzr+ssh`` and ``bzr`` paths can now be relative to home directories
1093
specified in the URL. Paths starting with a path segment of ``~`` are
1094
relative to the home directory of the user running the server, and paths
1095
starting with ``~user`` are relative to the home directory of the named
1096
user. For example, for a user "bob" with a home directory of
1097
``/home/bob``, these URLs are all equivalent:
1099
* ``bzr+ssh://bob@host/~/repo``
1100
* ``bzr+ssh://bob@host/~bob/repo``
1101
* ``bzr+ssh://bob@host/home/bob/repo``
1103
If ``bzr serve`` was invoked with a ``--directory`` argument, then no
1104
home directories outside that directory will be accessible via this
1107
This is a feature of ``bzr serve``, so pre-2.1 clients will
1108
automatically benefit from this feature when ``bzr`` on the server is
1109
upgraded. (Andrew Bennetts, #109143)
1111
* Extensions can now be compiled if either Cython or Pyrex is available.
1112
Currently Pyrex is preferred, but that may change in the future.
1115
* Give more control on BZR_PLUGIN_PATH by providing a way to refer to or
1116
disable the user, site and core plugin directories.
1117
(Vincent Ladeuil, #412930, #316192, #145612)
1122
* Bazaar's native protocol code now correctly handles EINTR, which most
1123
noticeably occurs if you break in to the debugger while connected to a
1124
bzr+ssh server. You can now can continue from the debugger (by typing
1125
'c') and the process continues. However, note that pressing C-\ in the
1126
shell may still kill the SSH process, which is bug 162509, so you must
1127
sent a signal to the bzr process specifically, for example by typing
1128
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
1130
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
1131
filename will issue a warning and skip over those files.
1132
(Robert Collins, #3918)
1134
* ``bzr dpush`` now aborts if uncommitted changes (including pending merges)
1135
are present in the working tree. The configuration option ``dpush_strict``
1136
can be used to set the default for this behavior.
1137
(Vincent Ladeuil, #438158)
1139
* ``bzr merge`` and ``bzr remove-tree`` now requires --force if pending
1140
merges are present in the working tree.
1141
(Vincent Ladeuil, #426344)
1143
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
1144
traceback. (Martin Pool, #109115)
1146
* Don't give a warning on Windows when failing to import ``_readdir_pyx``
1147
as it is never built. (John Arbash Meinel, #430645)
1149
* Don't restrict the command name used to run the test suite.
1150
(Vincent Ladeuil, #419950)
1152
* FTP transports were built differently when the kerberos python module was
1153
present leading to obscure failures related to ASCII/BINARY modes.
1154
(Vincent Ladeuil, #443041)
1156
* Network streams now decode adjacent records of the same type into a
1157
single stream, reducing layering churn. (Robert Collins)
1159
* PreviewTree behaves correctly when get_file_mtime is invoked on an unmodified
1160
file. (Aaron Bentley, #251532)
1162
* Registry objects should not use iteritems() when asked to use items().
1163
(Vincent Ladeuil, #430510)
1165
* Weave based repositories couldn't be cloned when committers were using
1166
domains or user ids embedding '.sig'. Now they can.
1167
(Matthew Fuller, Vincent Ladeuil, #430868)
1172
* Revision specifiers can now be given in a more DWIM form, without
1173
needing explicit prefixes for specifiers like tags or revision id's.
1174
See ``bzr help revisionspec`` for full details. (Matthew Fuller)
1176
* Bazaar gives a warning before exiting, and writes into ``.bzr.log``, if
1177
compiled extensions can't be loaded. This typically indicates a
1178
packaging or installation problem. In this case Bazaar will keep
1179
running using pure-Python versions, but this may be substantially
1180
slower. The warning can be disabled by setting
1181
``ignore_missing_extensions = True`` in ``bazaar.conf``.
1182
See also <https://answers.launchpad.net/bzr/+faq/703>.
1183
(Martin Pool, #406113, #430529)
1185
* Secondary errors that occur during Branch.unlock and Repository.unlock
1186
no longer obscure the original error. These methods now use a new
1187
decorator, ``only_raises``. This fixes many causes of
1188
``TooManyConcurrentRequests`` and similar errors.
1189
(Andrew Bennetts, #429747)
1194
* Describe the new shell-like test feature. (Vincent Ladeuil)
1196
* Help on hooks no longer says 'Not deprecated' for hooks that are
1197
currently supported. (Ian Clatworthy, #422415)
1202
* ``bzrlib.user_encoding`` has been removed; use
1203
``bzrlib.osutils.get_user_encoding`` instead. (Martin Pool)
1205
* ``bzrlib.tests`` now uses ``stopTestRun`` for its ``TestResult``
1206
subclasses - the same as python's unittest module. (Robert Collins)
1208
* ``diff._get_trees_to_diff`` has been renamed to
1209
``diff.get_trees_and_branches_to_diff``. It is now a public API, and it
1210
returns the old and new branches. (Gary van der Merwe)
1212
* ``bzrlib.trace.log_error``, ``error`` and ``info`` have been deprecated.
1215
* ``MutableTree.has_changes()`` does not require a tree parameter anymore. It
1216
now defaults to comparing to the basis tree. It now checks for pending
1217
merges too. ``Merger.check_basis`` has been deprecated and replaced by the
1218
corresponding has_changes() calls. ``Merge.compare_basis``,
1219
``Merger.file_revisions`` and ``Merger.ensure_revision_trees`` have also
1221
(Vincent Ladeuil, #440631)
1223
* ``ProgressTask.note`` is deprecated.

* Added ``-Drelock`` debug flag. It will ``note`` a message every time a
1230
repository or branch object is unlocked then relocked the same way.
1233
* ``BTreeLeafParser.extract_key`` has been tweaked slightly to reduce
1234
mallocs while parsing the index (approx 3=>1 mallocs per key read).
1235
This results in a 10% speedup while reading an index.
1236
(John Arbash Meinel)
1238
* The ``bzrlib.lsprof`` module has a new class ``BzrProfiler`` which makes
1239
profiling in some situations like callbacks and generators easier.
1245
* Passing ``--lsprof-tests -v`` to bzr selftest will cause lsprof output to
1246
be output for every test. Note that this is very verbose! (Robert Collins)
1248
* Setting ``BZR_TEST_PDB=1`` when running selftest will cause a pdb
1249
post_mortem to be triggered when a test failure occurs. (Robert Collins)
1251
* Shell-like tests can now be written. Code in ``bzrlib/tests/script.py`` ,
1252
documentation in ``developers/testing.txt`` for details.
1255
* Some tests could end up with the same id, that was dormant for
1257
(Vincent Ladeuil, #442980)
1259
* Stop showing the number of tests due to missing features in the test
1260
progress bar. (Martin Pool)
1262
* Test parameterisation now does a shallow copy, not a deep copy of the test
1263
to be parameterised. This is not expected to break external use of test
1264
parameterisation, and is substantially faster. (Robert Collins)
1266
* Tests that try to open a bzr dir on an arbitrary transport will now
1267
fail unless they have explicitly permitted the transport via
1268
``self.permit_url``. The standard test factories such as ``self.get_url``
1269
will permit the URLs they provide automatically, so only exceptional
1270
tests should need to do this. (Robert Collins)
1272
* The break-in test no longer cares about clean shutdown of the child,
1273
instead it is happy if the debugger starts up. (Robert Collins)
1275
* The full test suite is expected to pass when the C extensions are not
1276
present. (Vincent Ladeuil, #430749)
