:2.1.4: NOT RELEASED YET
16
* Launchpad has announced that the ``edge.launchpad.net`` instance is
17
deprecated and may be shut down in the future
18
<http://blog.launchpad.net/general/edge-is-deprecated>. Bazaar has therefore
19
been updated in this release to talk to the main (``launchpad.net``) servers,
20
rather than the ``edge`` ones. (Vincent Ladeuil, #583667)
28
* Avoid UnicodeDecodeError in ``bzr add`` with multiple files under a non-ascii
29
path on windows from symlink support addition. (Martin [gz], #686611)
31
* Skip tests that needs a bzr source tree when there isn't one. This is
32
needed to succesfully run the test suite for installed versions.
33
(Vincent Ladeuil, #644855).
35
* Skip the tests that requires respecting the chmod bits when running as root.
36
(Vincent Ladeuil, #646133)
38
* Using bzr with `lp:` URLs behind an HTTP proxy should work.
39
(Robert Collins, #558343)
63
The third release in our 2.1 series addresses several user-inconvenience bugs
64
(and includes the fixes done in 2.0.6). None are critical, but upgrading is
65
recommended for all users on earlier 2.1 releases.
70
* Additional merges after an unrelated branch has been merged with its
71
history no longer crash when deleted files are involved.
72
(Vincent Ladeuil, John Arbash Meinel, #375898)
74
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
75
previously-unversioned directory within the tree: the directory is
77
(Martin Pool, #192859)
79
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
80
target of the symlink.
81
(Martin Pool, John Arbash Meinel, #128562)
83
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
84
permissions as ``.bzr`` directory on a POSIX OS.
85
(Parth Malwankar, #262450)
87
* Configuration files in ``${BZR_HOME}`` are now written in an atomic
88
way which should help avoid problems with concurrent writers.
89
(Vincent Ladeuil, #525571)
91
* Don't traceback trying to unversion children files of an already
92
unversioned directory. (Vincent Ladeuil, #494221)
94
* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
95
contains only NUL bytes). Instead warn the user, and allow ``bzr
96
break-lock`` to remove it. (Andrew Bennetts, #619872)
98
* Fix ``AttributeError on parent.children`` when adding a file under a
99
directory that was a symlink in the previous commit.
100
(Martin Pool, #192859)
102
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
103
which can result in "missing referenced chk root keys" errors when
104
fetching from repositories with affected revisions.
105
(Andrew Bennetts, #522637)
107
* Raise ValueError instead of a string exception.
108
(John Arbash Meinel, #586926)
110
* Reduce peak memory by one copy of compressed text.
111
(John Arbash Meinel, #566940)
113
* Repositories accessed via a smart server now reject being stacked on a
114
repository in an incompatible format, as is the case when accessing them
115
via other methods. This was causing fetches from those repositories via
116
a smart server (e.g. using ``bzr branch``) to receive invalid data.
117
(Andrew Bennetts, #562380)
119
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
120
error. This error was caused by 2.0 not being updated when upstream
121
python merged the end of run patch, which chose ``stopTestRun`` rather than
122
``done``. (Robert Collins, #571437)
124
* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``
125
being thrown from ``xml_serializer`` on certain cElementTree setups.
126
(Martin [gz], #254278)
128
* When passing a file to ``UTF8DirReader`` make sure to close the current
129
directory file handle after the chdir fails. Otherwise when passing many
130
filenames into a command line ``bzr status`` we would leak descriptors.
131
(John Arbash Meinel, #583486)
136
* ``build_tree_contents`` can create symlinks.
137
(Martin Pool, John Arbash Meinel)
145
This release fixes two critical networking issues with older servers and
146
with interrupted system call errors when pushing or pulling. We recommend
147
upgrading to anyone running a 2.1.x version of bzr.
152
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
153
support of bzr-externals and scmproj plugins.
154
(Alexander Belchenko, bug #572098)
156
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
157
(Aaron Bentley, #559436)
159
* Do not register a SIGWINCH signal handler, instead just poll for the
160
terminal width as needed. This avoids the "Interrupted System Call"
161
problems that occur on POSIX with all currently released versions of
163
(Andrew Bennetts, #583941)
165
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
167
(Andrew Bennetts, #528041)
169
* Reset ``siginterrupt`` flag to False every time we handle a signal
170
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
171
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
172
errors compared to registering ``signal.signal`` directly.
175
* Reduce peak memory by one copy of compressed text.
176
(John Arbash Meinel, #566940)
178
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
179
(John Arbash Meinel, #582656)
181
* When passing a file to ``UTF8DirReader`` make sure to close the current
182
directory file handle after the chdir fails. Otherwise when passing many
183
filenames into a command line ``bzr status`` we would leak descriptors.
184
(John Arbash Meinel, #583486)
189
* ``_remember_remote_is_before`` no longer raises AssertionError when
190
suboptimal network behaviour is noticed; instead it just mutters to the
191
log file (and warns the user if they have set the ``hpss`` debug flag).
192
This was causing unnecessary aborts for performance bugs that are minor
194
(Andrew Bennetts, #528041)
202
This is a small bugfix release. Upgrading is recommended for anyone
203
running 2.1.0 or earlier.
208
* Allow syscalls to automatically restart when ``TextUIFactory``'s
209
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
210
IO, which are often poorly handled by Python's libraries and parts of
211
bzrlib. (Andrew Bennetts, #496813)
213
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
214
(Martin Pool, #331095)
216
* Fix plugin packaging on Windows. (Ian Clatworthy, #524162)
218
* Fix stub SFTP test server to call os.getcwdu().
219
(Vincent Ladeuil, #526221, #526353)
221
* Fixed CHM generation by moving the NEWS section template into
222
a separate file. (Ian Clatworthy, #524184)
224
* Merge correctly when this_tree is not a WorkingTree. (Aaron Bentley)
226
* Register SIGWINCH handler only when creating a ``TextUIFactory``; avoids
227
problems importing bzrlib from a non-main thread.
228
(Elliot Murphy, #521989)
230
* Repositories accessed via a smart server now reject being stacked on a
231
repository in an incompatible format, as is the case when accessing them
232
via other methods. This was causing fetches from those repositories via
233
a smart server (e.g. using ``bzr branch``) to receive invalid data.
234
(Andrew Bennetts, #562380)
236
* Standardize the error handling when creating a new ``StaticTuple``
237
(problems will raise TypeError). (Matt Nordhoff, #457979)
239
* Warn if pyrex is too old to compile the new ``SimpleSet`` and
240
``StaticTuple`` extensions, rather than having the build fail randomly.
241
(John Arbash Meinel, #449776)
246
* Added a link to the Desktop Guide. (Ian Clatworthy)
248
* Added What's New in Bazaar 2.1 document. (Ian Clatworthy)
250
* Drop Google Analytics from the core docs as they caused problems
251
in the CHM files. (Ian Clatworthy, #502010)
256
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
257
can set a signal handler and call ``signal.siginterrupt(signum,
258
False)`` for it, if the platform and Python version supports it.
259
(Andrew Bennetts, #496813)
265
:Codename: Strasbourg
268
This release marks our second long-term-stable series. The Bazaar team
269
has decided that we will continue to make bugfix-only 2.0.x and 2.1.x
270
releases, along with 2.2 development releases.
272
This is a fairly incremental update, focusing on polish and bugfixing.
273
There are no changes for supported disk formats. Key updates include
274
reduced memory consumption for many operations, a new per-file merge
275
hook, ignore patterns can now include '!' to exclude files, globbing
276
support for all commands on Windows, and support for addressing home
277
directories via ``bzr+ssh://host/~/`` syntax.
279
Users are encouraged to upgrade from the 2.0 stable series.
284
* Don't require testtools to use SFTP.
285
(Vincent Ladeuil, #516183)
287
* Fix "AttributeError in Inter1and2Helper" during fetch.
288
(Martin Pool, #513432)
290
* ``bzr update`` performs the two merges in a more logical order and will stop
291
when it encounters conflicts.
292
(Gerard Krol, #113809)
294
* Give a better error message when doing ``bzr bind`` in an already bound
295
branch. (Neil Martinsen-Burrell, #513063)
297
* Ignore ``KeyError`` from ``remove_index`` during ``_abort_write_group``
298
in a pack repository, which can happen harmlessly if the abort occurs during
299
finishing the write group. Also use ``bzrlib.cleanup`` so that any
300
other errors that occur while aborting the individual packs won't be
301
hidden by secondary failures when removing the corresponding indices.
302
(Andrew Bennetts, #423015)
304
* Set the mtime of files exported to a directory by ``bzr export`` all to
305
the same value to avoid confusing ``make`` and other date-based build
306
systems. (Robert Collins, #515631)
311
* Fetching into experimental formats will now print a warning. (Jelmer
317
* ``Repository.deserialise_inventory`` has been renamed to
318
``Repository._deserialise_inventory`` to indicate it is private.
321
* ``Repository.get_inventory_xml`` has been renamed to
322
``Repository._get_inventory_xml`` to indicate it is private.
325
* ``Repository.serialise_inventory`` has been renamed to
326
``Repository._serialise_inventory`` to indicate it is private.
328
* Using the ``bzrlib.chk_map`` module from within multiple threads at the
329
same time was broken due to race conditions with a module level page
330
cache. This shows up as a KeyError in the ``bzrlib.lru_cache`` code with
331
``bzrlib.chk_map`` in the backtrace, and can be triggered without using
332
the same high level objects such as ``bzrlib.repository.Repository``
333
from different threads. chk_map now uses a thread local cache which may
334
increase memory pressure on processes using threads.
335
(Robert Collins, John Arbash Meinel, #514090)
337
* The new ``merge_file_content`` should now be ok with tests to avoid
339
(Vincent Ladeuil, #515597)
344
* Use ``bzrlib.cleanup`` rather than less robust ``try``/``finally``
345
blocks in several places in ``bzrlib.merge``. This avoids masking prior
346
errors when errors like ``ImmortalPendingDeletion`` occur during cleanup
348
(Andrew Bennetts, #517275)
353
* The ``remove_index`` method of
354
``bzrlib.repofmt.pack_repo.AggregateIndex`` no longer takes a ``pack``
355
argument. This argument was always ignored.
356
(Andrew Bennetts, #423015)
361
:Codename: after the bubbles
362
:2.1.0rc2: 2010-01-29
364
This is a quick-turn-around to update a small issue with our new per-file
365
merge hook. We expect no major changes from this to the final 2.1.0.
370
* The new ``merge_file_content`` hook point has been altered to provide a
371
better API where state for extensions can be stored rather than the
372
too-simple function based approach. This fixes a performance regression
373
where branch configuration would be parsed per-file during merge. As
374
part of this the included news_merger has been refactored into a base
375
helper class ``bzrlib.merge.ConfigurableFileMerger``.
376
(Robert Collins, John Arbash Meinel, #513822)
382
:Codename: the 'new' stable
383
:2.1.0rc1: 2009-01-21
385
This is the first stable release candidate for Bazaar's 2.1 series. From
386
this point onwards, the 2.1 series will be considered stable (as the 2.0
387
series) and only bugfixes are expected to be incorporated. The dozen or so
388
bugfixes in the 2.0.4 release are also included in this release (along
389
with more than 15 more bugfixes). Some of the interesting features are
390
support for per-file merge hooks, ``bzr unshelve --preview``, support
391
for using ! in ignore files to exclude files from being ignored, a small
392
memory leak was squashed, and many ``ObjectNotLocked`` errors were fixed.
393
This looks to be a very good start for a new stable series.
399
* Add bug information to log output when available.
400
(Neil Martinsen-Burrell, Guillermo Gonzalez, #251729)
402
* Added ``merge_file_content`` hook point to ``Merger``, allowing plugins
403
to register custom merge logic, e.g. to provide smarter merging for
406
* Bazaar now includes the ``news_merge`` plugin. It is disabled by
407
default, to enable it add a ``news_merge_files`` option to your
408
configuration. Consult ``bzr help news_merge`` for more information.
411
* ``bzr branch`` now takes a ``--bind`` option. This lets you
412
branch and bind all in one command. (Ian Clatworthy)
414
* ``bzr switch`` now takes a ``--revision`` option, to allow switching to
415
a specific revision of a branch. (Daniel Watkins, #183559)
417
* ``bzr unshelve --preview`` can now be used to show how a patch on the
418
shelf would be applied to the working tree.
419
(Guilherme Salgado, #308122)
421
* ``bzr update`` now takes a ``--revision`` argument. This lets you
422
change the revision of the working tree to any revision in the
423
ancestry of the current or master branch. (Matthieu Moy, Mark Hammond,
426
* ``-Dbytes`` can now be used to display the total number of bytes
427
transferred for the current command. This information is always logged
428
to ``.bzr.log`` for later inspection. (John Arbash Meinel)
430
* New ignore patterns. Patterns prefixed with '!' are exceptions to
431
ignore patterns and take precedence over regular ignores. Such
432
exceptions are used to specify files that should be versioned which
433
would otherwise be ignored. Patterns prefixed with '!!' act as regular
434
ignore patterns, but have highest precedence, even over the '!'
435
exception patterns. (John Whitley, #428031)
437
* The ``supress_warnings`` configuration option has been introduced to disable
438
various warnings (it currently only supports the ``format_deprecation``
439
warning). The new option can be set in any of the following locations:
440
``bazaar.conf``, ``locations.conf`` and/or ``branch.conf``.
441
(Ted Gould, Matthew Fuller, Vincent Ladeuil)
446
* Always show a message if an OS error occurs while trying to run a
447
user-specified commit message editor.
448
(Martin Pool, #504842)
450
* ``bzr diff`` will now use the epoch when it is unable to determine
451
the timestamp of a file, if the revision it was introduced in is a
452
ghost. (Jelmer Vernooij, #295611)
454
* ``bzr switch -b`` can now create branches that are located using directory
455
services such as ``lp:``, even when the branch name doesn't contain a
456
'/'. (Neil Martinsen-Burrell, #495263)
458
* ``bzr unshelve`` has improved messages about what it is doing.
459
(Neil Martinsen-Burrell, #496917)
461
* Concurrent autopacking is more resilient to already-renamed pack files.
462
If we find that a file we are about to obsolete is already obsoleted, we
463
do not try to rename it, and we leave the file in ``obsolete_packs``.
464
The code is also fault tolerant if a file goes missing, assuming that
465
another process already removed the file.
466
(John Arbash Meinel, Gareth White, #507557)
468
* Fix "Too many concurrent requests" in reconcile when network connection
469
fails. (Andrew Bennetts, #503878)
471
* Fixed a side effect mutation of ``RemoteBzrDirFormat._network_name``
472
that caused some tests to fail when run in a non-default order.
473
Probably no user impact. (Martin Pool, #504102)
475
* Fixed ``ObjectNotLocked`` error in ``bzr cat -rbranch:../foo FILE``.
476
(Andrew Bennetts, #506274)
478
* FTP transports support Unicode paths by encoding/decoding them as utf8.
479
(Vincent Ladeuil, #472161)
481
* Listen to the SIGWINCH signal to update the terminal width.
482
(Vincent Ladeuil, #316357)
484
* Progress bars are now hidden when ``--quiet`` is given.
485
(Martin Pool, #320035)
487
* ``SilentUIFactory`` now supports ``make_output_stream`` and discards
488
whatever is written to it. This un-breaks some plugin tests that
489
depended on this behaviour.
490
(Martin Pool, #499757)
492
* When operations update the working tree, all affected files should end
493
up with the same mtime. (eg. when versioning a generated file, if you
494
update the source and the generated file together, the generated file
495
should appear up-to-date.)
496
(John Arbash Meinel, Martin <gzlist>, #488724)
501
* Added ``add_cleanup`` and ``cleanup_now`` to ``bzrlib.command.Command``.
502
All the builtin commands now use ``add_cleanup`` rather than
503
``try``/``finally`` blocks where applicable as it is simpler and more
504
robust. (Andrew Bennetts)
506
* All except a small number of storage formats are now hidden, making
507
the help for numerous commands far more digestible. (Ian Clatworthy)
509
* Attempts to open a shared repository as a branch (e.g. ``bzr branch
510
path/to/repo``) will now include "location is a repository" as a hint in
511
the error message. (Brian de Alwis, Andrew Bennetts, #440952)
513
* Push will now inform the user when they are trying to push to a foreign
514
VCS for which roundtripping is not supported, and will suggest them to
515
use dpush. (Jelmer Vernooij)
517
* The version of bzr being run is now written to the log file.
520
* Transport network activity indicator is shown more of the time when
521
Bazaar is doing network IO.
527
* Add documentation on creating merges with more than one parent.
528
(Neil Martinsen-Burrell, #481526)
530
* Better explain the --uncommitted option of merge.
531
(Neil Martinsen-Burrell, #505088)
533
* Improve discussion of pending merges in the documentation for
534
``revert``. (Neil Martinsen-Burrell, #505093)
536
* Improved help for ``bzr send``.
537
(Martin Pool, Bojan Nikolic)
539
* There is a System Administrator's Guide in ``doc/en/admin-guide``,
540
including discussions of installation, relevant plugins, security and
541
backup. (Neil Martinsen-Burrell)
543
* The ``conflicts`` help topic has been renamed to ``conflict-types``.
546
* The User Reference is now presented as a series of topics.
547
Many of the included topics have link and format tweaks applied.
553
* Added ``cachedproperty`` decorator to ``bzrlib.decorators``.
556
* Many test features were renamed from ``FooFeature`` to ``foo_feature``
557
to be consistent with instances being lower case and classes being
558
CamelCase. For the features that were more likely to be used, we added a
559
deprecation thunk, but not all. (John Arbash Meinel)
561
* Merger classes (such as ``Merge3Merger``) now expect a ``this_branch``
562
parameter in their constructors, and provide ``this_branch`` as an
563
attribute. (Andrew Bennetts)
565
* The Branch hooks pre_change_branch_tip no longer masks exceptions raised
566
by plugins - the original exceptions are now preserved. (Robert Collins)
568
* The Transport ``Server.tearDown`` method is now renamed to
569
``stop_server`` and ``setUp`` to ``start_server`` for consistency with
570
our normal naming pattern, and to avoid confusion with Python's
571
``TestCase.tearDown``. (Martin Pool)
573
* ``WorkingTree.update`` implementations must now accept a ``revision``
579
* Added ``BzrDir.open_branchV3`` smart server request, which can receive
580
a string of details (such as "location is a repository") as part of a
581
``nobranch`` response. (Andrew Bennetts, #440952)
583
* New helper osutils.UnicodeOrBytesToBytesWriter which encodes unicode
584
objects but passes str objects straight through. This is used for
585
selftest but may be useful for diff and other operations that generate
586
mixed output. (Robert Collins)
588
* New exception ``NoRoundtrippingSupport``, for use by foreign branch
589
plugins. (Jelmer Vernooij)
594
* ``bzrlib.tests.permute_for_extension`` is a helper that simplifies
595
running all tests in the current module, once against a pure python
596
implementation, and once against an extension (pyrex/C) implementation.
597
It can be used to dramatically simplify the implementation of
598
``load_tests``. (John Arbash Meinel)
600
* ``bzrlib.tests.TestCase`` now subclasses ``testtools.testcase.TestCase``.
601
This permits features in testtools such as getUniqueInteger and
602
getUniqueString to be used. Because of this, testtools version 0.9.2 or
603
newer is now a dependency to run bzr selftest. Running with versions of
604
testtools less than 0.9.2 will cause bzr to error while loading the test
605
suite. (Robert Collins)
607
* Shell-like tests now support the command "mv" for moving files. The
608
syntax for ``mv file1 file2``, ``mv dir1 dir2`` and ``mv file dir`` is
609
supported. (Neil Martinsen-Burrell)
611
* The test progress bar no longer distinguishes tests that 'errored' from
612
tests that 'failed' - they're all just failures.
619
:Codename: san francisco airport
622
The fourth beta release in the 2.1 series brings with it a significant
623
number of bugfixes (~20). The test suite is once again (finally) "green"
624
on Windows, and should remain that way for future releases. There are a
625
few performance related updates (faster upgrade and log), and several UI
626
tweaks. There has also been a significant number of tweaks to the runtime
627
documentation. 2.1.0b4 include everything from the 2.0.3 release.
633
* The BZR_SSH environmental variable may now be set to the path of a secure
634
shell client. If currently set to the value ``ssh`` it will now guess the
635
vendor of the program with that name, to restore the old behaviour that
636
indicated the SSH Corporation client use ``sshcorp`` instead as the magic
637
string. (Martin <gzlist@googlemail.com>, #176292)
642
* ``bzr commit`` now has a ``--commit-time`` option.
643
(Alexander Sack, #459276)
645
* ``-Dhpss`` now increases logging done when run on the bzr server,
646
similarly to how it works on the client. (John Arbash Meinel)
648
* New option ``bzr unshelve --keep`` applies the changes and leaves them
649
on the shelf. (Martin Pool, Oscar Fuentes, #492091)
651
* The ``BZR_COLUMNS`` envrionment variable can be set to force bzr to
652
respect a given terminal width. This can be useful when output is
653
redirected or in obscure cases where the default value is not
654
appropriate. Pagers can use it to get a better control of the line
658
* The new command ``bzr lp-mirror`` will request that Launchpad update its
659
mirror of a local branch. This command will only function if launchpadlib
667
* After renaming a file, the dirstate could accidentally reference
668
``source\\path`` rather than ``source/path`` on Windows. This might be a
669
source of some dirstate-related failures. (John Arbash Meinel)
671
* ``bzr commit`` now detects commit messages that looks like file names
672
and issues a warning.
673
(Gioele Barabucci, #73073)
675
* ``bzr ignore /`` no longer causes an IndexError. (Gorden Tyler, #456036)
677
* ``bzr log -n0 -rN`` should not return revisions beyond its merged revisions.
678
(#325618, #484109, Marius Kruger)
680
* ``bzr merge --weave`` and ``--lca`` will now create ``.BASE`` files for
681
files with conflicts (similar to ``--merge3``). The contents of the file
682
is a synthesis of all bases used for the merge.
683
(John Arbash Meinel, #40412)
685
* ``bzr mv --quiet`` really is quiet now. (Gordon Tyler, #271790)
687
* ``bzr serve`` is more clear about the risk of supplying --allow-writes.
688
(Robert Collins, #84659)
690
* ``bzr serve --quiet`` really is quiet now. (Gordon Tyler, #252834)
692
* Fix bug with redirected URLs over authenticated HTTP.
693
(Glen Mailer, Neil Martinsen-Burrell, Vincent Ladeuil, #395714)
695
* Interactive merge doesn't leave branch locks behind. (Aaron Bentley)
697
* Lots of bugfixes for the test suite on Windows. We should once again
698
have a test suite with no failures on Windows. (John Arbash Meinel)
700
* ``osutils.terminal_width()`` obeys the BZR_COLUMNS environment
701
variable but returns None if the terminal is not a tty (when output is
702
redirected for example). Also fixes its usage under OSes that doesn't
703
provide termios.TIOCGWINSZ. Make sure the corresponding tests runs on
705
(Joke de Buhr, Vincent Ladeuil, #353370, #62539)
706
(John Arbash Meinel, Vincent Ladeuil, #492561)
708
* Terminate SSH subprocesses when no references to them remain, fixing
709
subprocess and file descriptor leaks. (Andrew Bennetts, #426662)
711
* The ``--hardlink`` option of ``bzr branch`` and ``bzr checkout`` now
712
works for 2a format trees. Only files unaffected by content filters
713
will be hardlinked. (Andrew Bennetts, #408193)
715
* The new glob expansion on Windows would replace all ``\`` characters
716
with ``/`` even if it there wasn't a glob to expand, the arg was quoted,
717
etc. Now only change slashes if there is something being glob expanded.
718
(John Arbash Meinel, #485771)
720
* Use our faster ``KnownGraph.heads()`` functionality when computing the
721
new rich-root heads. This can cut a conversion time in half (mysql from
722
13.5h => 6.2h) (John Arbash Meinel, #487632)
724
* When launching a external diff tool via bzr diff --using, temporary files
725
are no longer created, rather, the path to the file in the working tree is
726
passed to the external diff tool. This allows the file to be edited if the
727
diff tool provides for this. (Gary van der Merwe, #490738)
729
* The launchpad-open command can now be used from a subdirectory of a
730
branch, not just from the root of the branch.
731
(Neil Martinsen-Burrell, #489102)
737
* ``bzr log`` is now faster. (Ian Clatworthy)
739
* ``bzr update`` provides feedback on which branch it is up to date with.
740
(Neil Martinsen-Burrell)
742
* ``bzr upgrade`` from pre-2a to 2a can be significantly faster (4x).
743
For details see the xml8 patch and heads() improvements.
746
* ``bzrlib.urlutils.local_path_from_url`` now accepts
747
'file://localhost/' as well as 'file:///' URLs on POSIX. (Michael
750
* The progress bar now shows only a spinner and per-operation counts,
751
not an overall progress bar. The previous bar was often not correlated
752
with real overall operation progress, either because the operations take
753
nonlinear time, or because at the start of the operation Bazaar couldn't
754
estimate how much work there was to do. (Martin Pool)
759
* Lots of documentation tweaks for inline help topics and command help
765
* ``bzrlib.textui`` (vestigial module) removed. (Martin Pool)
767
* The Launchpad plugin now has a function ``login`` which will log in to
768
Launchpad with launchpadlib, and ``load_branch`` which will return the
769
Launchpad Branch object corresponding to a given Bazaar Branch object.
775
* New test Feature: ``ModuleAvailableFeature``. It is designed to make it
776
easier to handle what tests you want to run based on what modules can be
777
imported. (Rather than lots of custom-implemented features that were
778
basically copy-and-pasted.) (John Arbash Meinel)
780
* ``osutils.timer_func()`` can be used to get either ``time.time()`` or
781
``time.clock()`` when you want to do performance timing.
782
``time.time()`` is limited to 15ms resolution on Windows, but
783
``time.clock()`` gives CPU and not wall-clock time on other platforms.
786
* Several code paths that were calling ``Transport.get().read()`` have
787
been changed to the equalivent ``Transport.get_bytes()``. The main
788
difference is that the latter will explicitly call ``file.close()``,
789
rather than expecting the garbage collector to handle it. This helps
790
with some race conditions on Windows during the test suite and SFTP
791
tests. (John Arbash Meinel)
796
* TestCaseWithMemoryTransport no longer sets $HOME and $BZR_HOME to
797
unicode strings. (Michael Hudson, #464174)
803
:Codename: after sprint recovery
806
This release was pushed up from its normal release cycle due to a
807
regression in python 2.4 compatibility in 2.1.0b2. Since this regression
808
was caught before 2.1.0b2 was officially announced, the full changelog
809
includes both 2.1.0b3 and 2.1.0b2 changes.
811
Highlights of 2.1.0b3 are: new globbing code for all commands on Windows,
812
the test suite now conforms to python's trunk enhanced semantics (skip,
813
etc.), and ``bzr info -v`` will now report the correct branch and repo
814
formats for Remote objects.
820
* Users can define a shelve editor to provide shelf functionality at a
821
granularity finer than per-patch-hunk. (Aaron Bentley)
826
* Fix for shell completion and short options. (Benoît PIERRE)
828
* Fix ``bzr --profile-imports`` with Python 2.6. (Martin Pool)
830
* Hooks daughter classes should always call the base constructor.
831
(Alexander Belchenko, Vincent Ladeuil, #389648)
833
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
835
* On Windows, do glob expansion at the command-line level (as is usually
836
done in bash, etc.) This means that *all* commands get glob expansion
837
(bzr status, bzr add, bzr mv, etc). It uses a custom command line
838
parser, which allows us to know if a given section was quoted. It means
839
you can now do ``bzr ignore "*.py"``.
840
(John Arbash Meinel, #425510, #426410, #194450)
842
* Sanitize commit messages that come in from the '-m' flag. We translate
843
'\r\n' => '\n' and a plain '\r' => '\n'. The storage layer doesn't
844
allow those because XML store silently translate it anyway. (The parser
845
auto-translates \r\n => \n in ways that are hard for us to catch.)
847
* Show correct branch and repository format descriptions in
848
``bzr info -v`` on a smart server location. (Andrew Bennetts, #196080)
850
* The fix for bug #186920 accidentally broke compatibility with python
851
2.4. (Vincent Ladeuil, #475585)
853
* Using ``Repository.get_commit_builder().record_iter_changes()`` now
854
correctly sets ``self.inv_sha1`` to a sha1 string and
855
``self.new_inventory`` to an Inventory instance after calling
856
``self.finish_inventory()``. (Previously it accidently set both values
857
as a tuple on ``self.inv_sha1``. This was missed because
858
``repo.add_revision`` ignores the supplied inventory sha1 and recomputes
859
the sha1 from the repo directly. (John Arbash Meinel)
861
* Shelve command refuse to run if there is no real terminal.
862
(Alexander Belchenko)
864
* Avoid unnecessarily flushing of trace file; it's now unbuffered at the
865
Python level. (Martin Pool)
870
* Include Japanese translations for documentation (Inada Naoki)
872
* New API ``ui_factory.make_output_stream`` to be used for sending bulk
873
(rather than user-interaction) data to stdout. This automatically
874
coordinates with progress bars or other terminal activity, and can be
876
(Martin Pool, 493944)
881
* Some of the core groupcompress functionality now releases the GIL before
882
operation. Similar to how zlib and bz2 operate without the GIL in the
883
core compression and decompression routines. (John Arbash Meinel)
888
* -Dhpssvfs will now trigger on ``RemoteBzrDir._ensure_real``, providing
889
more debugging of VFS access triggers. (Robert Collins)
891
* KnownFailure is now signalled to ``ExtendedTestResult`` using the same
892
method that Python 2.7 uses - ``addExpectedFailure``. (Robert Collins)
894
* ``--parallel=fork`` is now compatible with --subunit.
895
(Robert Collins, Vincent Ladeuil, #419776)
897
* Reporting of failures shows test ids not descriptions and thus shows
898
parameterised tests correctly. (Robert Collins)
900
* TestNotApplicable is now handled within the TestCase.run method rather
901
than being looked for within ``ExtendedTestResult.addError``. This
902
provides better handling with other ``TestResult`` objects, degrading to
903
sucess rather than error. (Robert Collins)
905
* The private method ``_testConcluded`` on ``ExtendedTestResult`` has been
906
removed - it was empty and unused. (Robert Collins)
908
* UnavailableFeature is now handled within the TestCase.run method rather
909
than being looked for within addError. If the Result object does not
910
have an addNotSupported method, addSkip is attempted instead, and
911
failing that addSuccess. (Robert Collins)
913
* When a TestResult does not have an addSkip method, skipped tests are now
914
reported as successful tests, rather than as errors. This change is
915
to make it possible to get a clean test run with a less capable
916
TestResult. (Robert Collins)
923
:Codename: a load off my mind
926
This is our second feature-filled release since 2.0, pushing us down the
927
path to a 2.1.0. Once again, all bugfixes in 2.0.2 are present in 2.1.0b2.
929
Key highlights in this release are: improved handling of
930
failures-during-cleanup for commit, fixing a long-standing bug with
931
``bzr+http`` and shared repositories, all ``lp:`` URLs to be resolved
932
behind proxies, and a new StaticTuple datatype, allowing us to reduce
933
memory consumption (50%) and garbage collector overhead (40% faster) for
936
* A new ``--concurrency`` option has been added as well as an associated
937
BZR_CONCURRENCY environment variable to specify the number of
938
processes that can be run concurrently when running ``bzr selftest``. The
939
command-line option overrides the environment variable if both are
940
specified. If none is specified. the number of processes is obtained
941
from the OS as before. (Matt Nordhoff, Vincent Ladeuil)
946
* ``bzr+http`` servers no longer give spurious jail break errors when
947
serving branches inside a shared repository. (Andrew Bennetts, #348308)
949
* Errors during commit are handled more robustly so that knock-on errors
950
are less likely to occur, and will not obscure the original error if
951
they do occur. This fixes some causes of ``TooManyConcurrentRequests``
952
and similar errors. (Andrew Bennetts, #429747, #243391)
954
* Launchpad URLs can now be resolved from behind proxies.
955
(Gordon Tyler, Vincent Ladeuil, #186920)
957
* Reduce the strictness for StaticTuple, instead add a debug flag
958
``-Dstatic_tuple`` which will change apis to be strict and raise errors.
959
This way, most users won't see failures, but developers can improve
960
internals. (John Arbash Meinel, #471193)
962
* TreeTransform.adjust_path updates the limbo paths of descendants of adjusted
963
files. (Aaron Bentley)
965
* Unicode paths are now handled correctly and consistently by the smart
966
server. (Andrew Bennetts, Michael Hudson, #458762)
971
* When reading index files, we now use a ``StaticTuple`` rather than a
972
plain ``tuple`` object. This generally gives a 20% decrease in peak
973
memory, and can give a performance boost up to 40% on large projects.
976
* Peak memory under certain operations has been reduced significantly.
977
(eg, 'bzr branch launchpad standalone' is cut in half)
983
* Filtered views user documentation upgraded to refer to format 2a
984
instead of pre-2.0 formats. (Ian Clatworthy)
989
* Remove deprecated ``CLIUIFactory``. (Martin Pool)
991
* ``UIFactory`` now has new ``show_error``, ``show_message`` and
992
``show_warning`` methods, which can be hooked by non-text UIs.
998
* Added ``bzrlib._simple_set_pyx``. This is a hybrid between a Set and a
999
Dict (it only holds keys, but you can lookup the object located at a
1000
given key). It has significantly reduced memory consumption versus the
1001
builtin objects (1/2 the size of Set, 1/3rd the size of Dict). This is
1002
used as the interning structure for StaticTuple objects.
1003
(John Arbash Meinel)
1005
* ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
1006
the btree index parser and the chk map parser. This class functions
1007
similarly to ``tuple`` objects. However, it can only point to a limited
1008
collection of types. (Currently StaticTuple, str, unicode, None, bool,
1009
int, long, float, but not subclasses). This allows us to remove it from
1010
the garbage collector (it cannot be in a cycle), it also allows us to
1011
intern the objects. In testing, this can reduce peak memory by 20-40%,
1012
and significantly improve performance by removing objects from being
1013
inspected by the garbage collector. (John Arbash Meinel)
1015
* ``GroupCompressBlock._ensure_content()`` will now release the
1016
``zlib.decompressobj()`` when the first request is for all of the
1017
content. (Previously it would only be released if you made a request for
1018
part of the content, and then all of it later.) This turns out to be a
1019
significant memory savings, as a ``zstream`` carries around approx 260kB
1020
of internal state and buffers. (For branching bzr.dev this drops peak
1021
memory from 382MB => 345MB.) (John Arbash Meinel)
1023
* When streaming content between ``2a`` format repositories, we now clear
1024
caches from earlier versioned files. (So 'revisions' is cleared when we
1025
start reading 'inventories', etc.) This can have a significant impact on
1026
peak memory for initial copies (~200MB). (John Arbash Meinel)
1032
:Codename: While the cat is away
1033
:2.1.0b1: 2009-10-14
1035
This is the first development release in the new split "stable" and
1036
"development" series. As such, the release is a snapshot of bzr.dev
1037
without creating a release candidate first. This release includes a
1038
fair amount of internal changes, with deprecated code being removed,
1039
and several new feature developments. People looking for a stable code
1040
base with only bugfixes should focus on the 2.0.1 release. All bugfixes
1041
present in 2.0.1 are present in 2.1.0b1.
1043
Highlights include support for ``bzr+ssh://host/~/homedir`` style URLs,
1044
finer control over the plugin search path via extended BZR_PLUGIN_PATH
1045
syntax, visible warnings when extension modules fail to load, and improved
1046
error handling during unlocking.
1052
* Bazaar can now send mail through Apple OS X Mail.app.
1055
* ``bzr+ssh`` and ``bzr`` paths can now be relative to home directories
1056
specified in the URL. Paths starting with a path segment of ``~`` are
1057
relative to the home directory of the user running the server, and paths
1058
starting with ``~user`` are relative to the home directory of the named
1059
user. For example, for a user "bob" with a home directory of
1060
``/home/bob``, these URLs are all equivalent:
1062
* ``bzr+ssh://bob@host/~/repo``
1063
* ``bzr+ssh://bob@host/~bob/repo``
1064
* ``bzr+ssh://bob@host/home/bob/repo``
1066
If ``bzr serve`` was invoked with a ``--directory`` argument, then no
1067
home directories outside that directory will be accessible via this
1070
This is a feature of ``bzr serve``, so pre-2.1 clients will
1071
automatically benefit from this feature when ``bzr`` on the server is
1072
upgraded. (Andrew Bennetts, #109143)
1074
* Extensions can now be compiled if either Cython or Pyrex is available.
1075
Currently Pyrex is preferred, but that may change in the future.
1078
* Give more control on BZR_PLUGIN_PATH by providing a way to refer to or
1079
disable the user, site and core plugin directories.
1080
(Vincent Ladeuil, #412930, #316192, #145612)
1085
* Bazaar's native protocol code now correctly handles EINTR, which most
1086
noticeably occurs if you break in to the debugger while connected to a
1087
bzr+ssh server. You can now can continue from the debugger (by typing
1088
'c') and the process continues. However, note that pressing C-\ in the
1089
shell may still kill the SSH process, which is bug 162509, so you must
1090
sent a signal to the bzr process specifically, for example by typing
1091
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
1093
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
1094
filename will issue a warning and skip over those files.
1095
(Robert Collins, #3918)
1097
* ``bzr dpush`` now aborts if uncommitted changes (including pending merges)
1098
are present in the working tree. The configuration option ``dpush_strict``
1099
can be used to set the default for this behavior.
1100
(Vincent Ladeuil, #438158)
1102
* ``bzr merge`` and ``bzr remove-tree`` now requires --force if pending
1103
merges are present in the working tree.
1104
(Vincent Ladeuil, #426344)
1106
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
1107
traceback. (Martin Pool, #109115)
1109
* Don't give a warning on Windows when failing to import ``_readdir_pyx``
1110
as it is never built. (John Arbash Meinel, #430645)
1112
* Don't restrict the command name used to run the test suite.
1113
(Vincent Ladeuil, #419950)
1115
* FTP transports were built differently when the kerberos python module was
1116
present leading to obscure failures related to ASCII/BINARY modes.
1117
(Vincent Ladeuil, #443041)
1119
* Network streams now decode adjacent records of the same type into a
1120
single stream, reducing layering churn. (Robert Collins)
1122
* PreviewTree behaves correctly when get_file_mtime is invoked on an unmodified
1123
file. (Aaron Bentley, #251532)
1125
* Registry objects should not use iteritems() when asked to use items().
1126
(Vincent Ladeuil, #430510)
1128
* Weave based repositories couldn't be cloned when committers were using
1129
domains or user ids embedding '.sig'. Now they can.
1130
(Matthew Fuller, Vincent Ladeuil, #430868)
1135
* Revision specifiers can now be given in a more DWIM form, without
1136
needing explicit prefixes for specifiers like tags or revision id's.
1137
See ``bzr help revisionspec`` for full details. (Matthew Fuller)
1139
* Bazaar gives a warning before exiting, and writes into ``.bzr.log``, if
1140
compiled extensions can't be loaded. This typically indicates a
1141
packaging or installation problem. In this case Bazaar will keep
1142
running using pure-Python versions, but this may be substantially
1143
slower. The warning can be disabled by setting
1144
``ignore_missing_extensions = True`` in ``bazaar.conf``.
1145
See also <https://answers.launchpad.net/bzr/+faq/703>.
1146
(Martin Pool, #406113, #430529)
1148
* Secondary errors that occur during Branch.unlock and Repository.unlock
1149
no longer obscure the original error. These methods now use a new
1150
decorator, ``only_raises``. This fixes many causes of
1151
``TooManyConcurrentRequests`` and similar errors.
1152
(Andrew Bennetts, #429747)
1157
* Describe the new shell-like test feature. (Vincent Ladeuil)
1159
* Help on hooks no longer says 'Not deprecated' for hooks that are
1160
currently supported. (Ian Clatworthy, #422415)
1165
* ``bzrlib.user_encoding`` has been removed; use
1166
``bzrlib.osutils.get_user_encoding`` instead. (Martin Pool)
1168
* ``bzrlib.tests`` now uses ``stopTestRun`` for its ``TestResult``
1169
subclasses - the same as python's unittest module. (Robert Collins)
1171
* ``diff._get_trees_to_diff`` has been renamed to
1172
``diff.get_trees_and_branches_to_diff``. It is now a public API, and it
1173
returns the old and new branches. (Gary van der Merwe)
1175
* ``bzrlib.trace.log_error``, ``error`` and ``info`` have been deprecated.
1178
* ``MutableTree.has_changes()`` does not require a tree parameter anymore. It
1179
now defaults to comparing to the basis tree. It now checks for pending
1180
merges too. ``Merger.check_basis`` has been deprecated and replaced by the
1181
corresponding has_changes() calls. ``Merge.compare_basis``,
1182
``Merger.file_revisions`` and ``Merger.ensure_revision_trees`` have also
1184
(Vincent Ladeuil, #440631)
1186
* ``ProgressTask.note`` is deprecated.
1192
* Added ``-Drelock`` debug flag. It will ``note`` a message every time a
1193
repository or branch object is unlocked then relocked the same way.
1196
* ``BTreeLeafParser.extract_key`` has been tweaked slightly to reduce
1197
mallocs while parsing the index (approx 3=>1 mallocs per key read).
1198
This results in a 10% speedup while reading an index.
1199
(John Arbash Meinel)

* The ``bzrlib.lsprof`` module has a new class ``BzrProfiler`` which makes
1202
profiling in some situations like callbacks and generators easier.
1208
* Passing ``--lsprof-tests -v`` to bzr selftest will cause lsprof output to
1209
be output for every test. Note that this is very verbose! (Robert Collins)
1211
* Setting ``BZR_TEST_PDB=1`` when running selftest will cause a pdb
1212
post_mortem to be triggered when a test failure occurs. (Robert Collins)
1214
* Shell-like tests can now be written. Code in ``bzrlib/tests/script.py`` ,
1215
documentation in ``developers/testing.txt`` for details.
1218
* Some tests could end up with the same id, that was dormant for
1220
(Vincent Ladeuil, #442980)
1222
* Stop showing the number of tests due to missing features in the test
1223
progress bar. (Martin Pool)
1225
* Test parameterisation now does a shallow copy, not a deep copy of the test
1226
to be parameterised. This is not expected to break external use of test
1227
parameterisation, and is substantially faster. (Robert Collins)
1229
* Tests that try to open a bzr dir on an arbitrary transport will now
1230
fail unless they have explicitly permitted the transport via
1231
``self.permit_url``. The standard test factories such as ``self.get_url``
1232
will permit the URLs they provide automatically, so only exceptional
1233
tests should need to do this. (Robert Collins)
1235
* The break-in test no longer cares about clean shutdown of the child,
1236
instead it is happy if the debugger starts up. (Robert Collins)
1238
* The full test suite is expected to pass when the C extensions are not
1239
present. (Vincent Ladeuil, #430749)
