:2.2b3: NOT RELEASED YET
19
* ``bzr commit`` accepts ``-p`` (for "patch") as a shorter name for
21
(Parth Malwankar, #571467)
23
* ``bzr ignore`` now supports a ``--default-rules`` option that displays
24
the default ignore rules used by bzr. The flag ``--old-default-rules``
25
is no longer supported by ``ignore``.
26
(Parth Malwankar, #538703)
28
* ``bzr pack`` now supports a ``--clean-obsolete-packs`` option that
29
can save disk space by deleting obsolete pack files created during the
31
(Parth Malwankar, #304320)
36
* ``.bazaar``, ``.bazaar/bazaar.conf`` and ``.bzr.log`` inherit user and
37
group ownership from the containing directory. This allow bzr to work
39
(Martin <gzlist@googlemail.com>, Parth Malwankar, #376388)
41
* ``bzr log --exclude-common-ancestry -r X..Y`` displays the revisions that
42
are part of Y ancestry but not part of X ancestry (aka the graph
44
(Vincent Ladeuil, #320119)
46
* ``bzr selftest --parallel=fork`` wait for its children avoiding zombies.
47
(Vincent Ladeuil, #566670)
49
* ``bzr selftest`` should not use ui.note() since it's not unicode safe.
50
(Vincent Ladeuil, #563997)
52
* Don't mention --no-strict when we just issue the warning about unclean trees.
53
(Vincent Ladeuil, #401599)
55
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
57
(Andrew Bennetts, #528041)
59
* Reduce peak memory by one copy of compressed text.
60
(John Arbash Meinel, #566940)
62
* Show the filenames when a file rename fails so that the error will be
64
(Martin Pool, #491763)
69
* ``append_revisions_only`` will now be interpreted as a boolean and a
70
warning emitted if illegal values are used. Note that for projects
71
that needs to maintain compatibility with previsous bzr versions,
72
only 'True' and 'False' strings must be used (previous versions of
73
bzr will interpret all strings differing from 'True'
74
(case-sensitive) as false.
75
(Brian de Alwis, Vincent Ladeuil)
77
* ``Config.get_user_option_as_bool`` will now warn if a value cannot
78
be interpreted as a boolean.
87
* Added ``bzrlib.merge.PerFileMerger``, a more convenient way to write
88
some kinds of ``merge_file_content`` hook functions.
91
* `BzrDir`, `Branch`, `Repository` and `WorkingTree` now all support `user_url`,
92
`user_transport`, `control_url` and `control_transport` members pointing
93
respectively to the directory containing the ``.bzr`` control directory,
94
and to the directory within ``.bzr`` used for the particular component.
95
All of them inherit from `ControlComponent` which provides default
99
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
100
expected to return an object which can be used to unlock them. This reduces
101
duplicate code when using cleanups. The previous 'tokens's returned by
102
``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
103
on the result of the lock_write. ``repository.RepositoryWriteLockResult``
104
and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
109
* ``log._get_info_for_log_files`` now takes an add_cleanup callable.
112
* ``_remember_remote_is_before`` no longer raises AssertionError when
113
suboptimal network behaviour is noticed; instead it just mutters to the
114
log file (and warns the user if they have set the ``hpss`` debug flag).
115
This was causing unnecessary aborts for performance bugs that are minor
117
(Andrew Bennetts, #528041)
119
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
120
files loaded from disk. To ensure docstrings needed for help are never
121
stripped, the prefix ``__doc__ =`` should now be used.
122
(Martin <gzlist@googlemail.com>)
127
* Added ``bzrlib.tests.matchers`` as a place to put matchers, along with
128
our first in-tree matcher. See the module docstring for details.
131
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
132
(Gordon Tyler, #551332)
134
* Workaround ``Crypto.Random`` check leading to spurious test
135
failures on Lucid, FreeBSD and gentoo.
136
(Vincent Ladeuil, #528436)
143
This is a somewhat early second beta of the 2.2 series, to fix a python2.4
144
incompatibility in the 2.2b1 release. It also includes a swag of
145
performance, usability and correctness improvements: test feedback on all
146
of these would be welcome.
152
* ``bzr diff`` now supports a --format option, which can be used to
153
select alternative diff formats. (Jelmer Vernooij, #555994)
158
* ``bzr dpush``, ``bzr push`` and ``bzr send`` will now issue a warning
159
instead of failing when dirty trees are involved. The corresponding
160
``dpush_strict``, ``push_strict`` and ``send_strict`` should be set to
161
True explicitly to get the previous behaviour.
162
(Vincent Ladeuil, #519319)
164
* ``bzr export`` to tar file does not fail if any parent directory
165
contains unicode characters. This works around upstream Python bug
166
http://bugs.python.org/issue8396 .
167
(Parth Malwankar, #413406)
169
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
170
(Aaron Bentley, #559436)
172
* ``bzr update`` when a pending merge in the working tree has been merged
173
into the master branch will no longer claim that old commits have become
174
pending merges. (Robert Collins, #562079)
176
* ``bzrlib.mutabletree.MutableTree.commit`` will now support a passed in
177
config as in previous versions of bzrlib. (Robert Collins)
179
* Fix glitch in the warning about unclean trees display.
180
(Vincent Ladeuil, #562665)
182
* Fixed Python2.4 incompatibilities in the bzr2.2b1 source tarball.
185
* Help messages generated by ``RegistryOption.from_kwargs`` list the
186
switches in alphabetical order, rather than in an undefined order.
187
(Martin von Gagern, #559409)
189
* Make sure the ``ExecutablePath`` and ``InterpreterPath`` are set in
190
Apport crash reports, to avoid "This problem report applies to a program
191
which is not installed any more" error.
192
(Martin Pool, James Westby, #528114)
194
* Reset ``siginterrupt`` flag to False every time we handle a signal
195
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
196
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
197
errors after two window resizes.
200
* When invoked with a range revision, ``bzr log`` doesn't show revisions
201
that are not part of the Y revisions ancestry anymore when invoked with
203
(Vincent Ladeuil, #474807)
205
* Properly handle ``param_name`` attribute for ``ListOption``.
206
(Martin von Gagern, 387117)
211
* ``bzr commit`` will prompt before using a commit message that was
212
generated by a template and not edited by the user.
213
(Robert Collins, #530265)
215
* ``bzr diff`` read-locks the trees and branches only once, saving about
216
10-20ms on ``bzr diff`` in a bzr.dev tree.
219
* ``bzr missing`` read-locks the branches only once.
222
* ``bzr pull`` locks the branches and tree only once.
225
* Index lookups in pack repositories search recently hit pack files first.
226
In repositories with many pack files this can greatly reduce the
227
number of files accessed, the number of bytes read, and the number of
228
read calls. An incremental pull via plain HTTP takes half the time and
229
bytes for a moderately large repository. (Andrew Bennetts)
231
* Index lookups only re-order the indexes when the hit files aren't
232
already first. Reduces the cost of reordering
233
(John Arbash Meinel, #562429)
235
* Less code is loaded at startup. (Cold-cache start time is about 10-20%
237
(Martin Pool, #553017)
242
* ``bzrlib.diff.get_trees_and_branches_to_diff`` is deprecated. Use
243
``get_trees_and_branches_to_diff_locked`` instead.
249
* ``bzrlib.commands.Command.run_direct`` is no longer needed - the pre
250
2.1 method of calling run() to perform testing or direct use via the API
251
is now possible again. As part of this, the _operation attribute on
252
Command is now transient and only exists for the duration of ``run()``.
263
* BTreeGraphIndex can now take an offset to indicate that the data starts
264
somewhere other than then beginning of the file. (John Arbash Meinel)
266
* Deleted very old hidden commands ``versionedfile-list``,
267
``weave-plan-merge``, ``weave-merge-text``.
270
* ``Repository.get_inventory_sha1()`` and ``Repository.get_revision_xml()``
271
have been removed. (Jelmer Vernooij)
273
* ``Repository.get_revision_inventory()`` has been removed in favor of
274
``Repository.get_inventory()``. (Jelmer Vernooij)
276
* All test servers have been moved out of the bzrlib.transport hierarchy to
277
bzrlib.tests.test_server *except* for MemoryServer, ChrootServer and
278
PathFilteringServer. ``bzrlib`` users may encounter test failures that can
279
be fixed by updating the related imports from ``bzrlib.transport.xxx`` to
280
``bzrlib.tests.test_server``.
283
* ``BranchReferenceFormat.initialize()`` now takes an optional name argument
284
as its second parameter, for consistency with the initialize() method of
285
other formats. (Jelmer Vernooij)
290
* Added ``bzr remove-branch`` command that can remove a local or remote
291
branch. (Jelmer Vernooij, #276295)
293
* ``bzr export`` now takes an optional argument ``--per-file-timestamps``
294
to set file mtimes to the last timestamp of the last revision in which
295
they were changed rather than the current time. (Jelmer Vernooij)
297
* If the Apport crash-reporting tool is available, bzr crashes are now
298
stored into the ``/var/crash`` apport spool directory, and the user is
299
invited to report them to the developers from there, either
300
automatically or by running ``apport-bug``. No information is sent
301
without specific permission from the user. (Martin Pool, #515052)
303
* Parsing of command lines, for example in ``diff --using``, no longer
304
treats backslash as an escape character on Windows. (Gordon Tyler,
307
* Plugins can be disabled by defining ``BZR_DISABLE_PLUGINS`` as
308
a list of plugin names separated by ':' (';' on windows).
309
(Vincent Ladeuil, #411413)
311
* Plugins can be loaded from arbitrary locations by defining
312
``BZR_PLUGINS_AT`` as a list of name@path separated by ':' (';' on
313
windows). This takes precedence over ``BZR_PLUGIN_PATH`` for the
314
specified plugins. This is targeted at plugin developers for punctual
315
needs and *not* intended to replace ``BZR_PLUGIN_PATH``.
316
(Vincent Ladeuil, #82693)
318
* Tag names can now be determined automatically by ``automatic_tag_name``
319
hooks on ``Branch`` if they are not specified on the command line.
322
* Tree-shape conflicts can be resolved by providing ``--take-this`` and
323
``--take-other`` to the ``bzr resolve`` command. Just marking the conflict
324
as resolved is still accessible via the ``--done`` default action.
327
* Merges can be proposed on Launchpad with the new lp-propose-merge command.
328
(Aaron Bentley, Jonathan Lange)
333
* Added docstring for ``Tree.iter_changes``
334
(John Arbash Meinel, #304182)
336
* Allow additional arguments to
337
``RemoteRepository.add_inventory_by_delta()``. (Jelmer Vernooij, #532631)
339
* Allow exporting a single file using ``bzr export``.
340
(Michal Junák, #511987)
342
* Allow syscalls to automatically restart when ``TextUIFactory``'s
343
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
344
IO, which are often poorly handled by Python's libraries and parts of
345
bzrlib. (Andrew Bennetts, #496813)
347
* Avoid infinite recursion when probing for apport.
348
(Vincent Ladeuil, #516934)
350
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
351
(Martin Pool, #331095)
353
* Avoid truncating svn URLs.
354
(Martin Pool, Martin von Gagern, #545185)
356
* ``bzr add`` will not add conflict related files unless explicitly required.
357
(Vincent Ladeuil, #322767, #414589)
359
* ``bzr dump-btree`` now works on ``*.cix`` and ``*.six`` files. Those
360
indices do not have reference lists, so ``dump-btree`` will simply show
361
``None`` instead. (Andrew Bennetts, #488607)
363
* ``bzr help`` will no longer trigger the get_missing_command hook when
364
doing a topic lookup. This avoids prompting (like 'no command plugins/loom,
365
did you mean log?') when getting help. In future we may trigger the hook
366
deliberately when no help topics match from any help index.
367
(Robert Collins, #396261)
369
* ``bzr log -n0 -r..A.B.C`` should not crash but just consider the None
370
revspec as representing the first revision of the branch.
371
(Vincent Ladeuil, #519862)
373
* ``bzr remove-tree`` can now remove multiple working trees.
374
(Jared Hance, Andrew Bennetts, #253137)
376
* ``bzr resolve --take-this`` and ``--take-other`` now correctly renames
377
the kept file on content conflicts where one side deleted the file.
378
(Vincent Ladeuil, #529968)
380
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
381
permissions as ``.bzr`` directory on a POSIX OS.
382
(Parth Malwankar, #262450)
384
* ``bzr upgrade`` now names backup directory as ``backup.bzr.~N~`` instead
385
of ``backup.bzr``. This directory is ignored by bzr commands such as
387
(Parth Malwankar, #335033, #300001)
389
* Cope with non-utf8 characters inside ``.bzrignore``.
390
(Jason Spashett, #183504)
392
* Correctly interpret "451 Rename/move failure: Directory not empty" from
393
ftp servers while trying to take a lock.
394
(Martin Pool, #528722)
396
* DirStateRevisionTree.kind() was returning wrong result when 'kind'
397
changes occured between the workingtree and one of its parents.
398
(Vincent Ladeuil, #535547)
400
* Fix ``log`` to better check ancestors even if merged revisions are involved.
401
(Vincent Ladeuil, #476293)
403
* Loading a plugin from a given path with ``BZR_PLUGINS_AT`` doesn't depend
404
on os.lisdir() order and is now reliable.
405
(Vincent Ladeuil, #552922).
407
* Many IO operations that returned ``EINTR`` were retried even if it
408
wasn't safe to do so via careless use of ``until_no_eintr``. Bazaar now
409
only retries operations that are safe to retry, and in some cases has
410
switched to operations that can be retried (e.g. ``sock.send`` rather than
412
(Andrew Bennetts, Martin <gzlist@googlemail.com>, #496813)
414
* Path conflicts now support --take-this and --take-other even when a
415
deletion is involved.
416
(Vincent Ladeuil, #531967)
418
* Network transfer amounts and rates are now displayed in SI units according
419
to the Ubuntu Units Policy <https://wiki.ubuntu.com/UnitsPolicy>.
420
(Gordon Tyler, #514399)
422
* Support kind markers for socket and fifo filesystem objects. This
423
prevents ``bzr status --short`` from crashing when those files are
424
present. (John Arbash Meinel, #303275)
426
* ``bzr mkdir DIR`` will not create DIR unless DIR's parent is a versioned
427
directory. (Parth Malwankar, #138600)
429
* SSH child processes will now ignore SIGQUIT on nix systems so breaking into
430
the debugger won't kill the session.
431
(Martin <gzlist@googlemail.com>, #162502)
433
* Tolerate patches with leading noise in ``bzr-handle-patch``.
434
(Toshio Kuratomi, Martin Pool, #502076)
436
* ``update -r`` now supports updating to revisions that are not on
437
mainline (i.e. it supports dotted revisions).
438
(Parth Malwankar, #517800)
440
* Use first apparent author not committer in GNU Changelog format.
441
(Martin von Gagern, #513322)
446
* ``bzrlib.merge_directive._BaseMergeDirective`` has been renamed to
447
``bzrlib.merge_directive.BaseMergeDirective`` and is now public.
450
* ``BranchFormat.initialize`` now takes an optional ``name`` of the colocated
451
branch to create. (Jelmer Vernooij)
453
* ``BzrDir.get_branch_transport`` now takes an optional ``name`` of the
454
colocated branch to open. (Jelmer Vernooij)
456
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
457
can set a signal handler and call ``signal.siginterrupt(signum,
458
False)`` for it, if the platform and Python version supports it.
459
(Andrew Bennetts, #496813)
461
* New ``bzrlib.initialize`` is recommended for programs using bzrlib to
462
run when starting up; it sets up several things that previously needed
463
to be done separately.
464
(Martin Pool, #507710)
466
* Exporters now support a ``per_file_timestamps`` argument to write out the
467
timestamp of the commit in which a file revision was introduced.
470
* New method ``BzrDir.list_branches()`` that returns a sequence of branches
471
present in a control directory. (Jelmer Vernooij)
473
* New method ``Repository.get_known_graph_ancestry()``.
474
(Jelmer Vernooij, #495502)
476
* New transport methods ``readlink``, ``symlink`` and ``hardlink``.
479
* Remove unused ``CommandFailed`` exception.
485
* ``bzrlib.branchbuilder.BranchBuilder.build_snapshot`` now accepts a
486
``message_callback`` in the same way that commit does. (Robert Collins)
488
* ``bzrlib.builtins.Commit.run`` raises ``bzrlib.errors.BoundBranchOutOfDate``
489
rather than ``bzrlib.errors.BzrCommandError`` when the bound branch is out
490
of date. (Gary van der Merwe)
492
* ``bzrlib.commands.run_bzr`` is more extensible: callers can supply the
493
functions to load or disable plugins if they wish to use a different
494
plugin mechanism; the --help, --version and no-command name code paths
495
now use the generic pluggable command lookup infrastructure.
498
* ``bzrlib.errors.BoundBranchOutOfDate`` has a new field ``extra_help``
499
which can be set to add extra help to the error. (Gary van der Merwe)
501
* New method ``Branch.automatic_tag_name`` that can be used to find the
502
tag name for a particular revision automatically. (Jelmer Vernooij)
504
* The methods ``BzrDir.create_branch()``, ``BzrDir.destroy_branch()`` and
505
``BzrDir.open_branch()`` now take an optional ``name`` argument.
511
* bzr now has a ``.testr.conf`` file in its source tree configured
512
appropriately for running tests with Testrepository
513
(``https://launchpad.net/testrepository``). (Robert Collins)
515
* Documentation about testing with ``subunit`` has been tweaked.
518
* Known failures has been added for resolve --take-other on ParentLoop
519
conflicts. This reflects bug #537956 without fixing it.
522
* New ``bzrlib.tests.test_import_tariff`` can make assertions about what
523
Python modules are loaded, to guard against startup time or library
524
dependency regressions.
527
* PQM will now run with subunit output. To analyze a PQM error use
528
tribunal, or cat log | subunit-filter | subunit2pyunit. (Robert Collins)
530
* Stop sending apport crash files to ``.cache`` in the directory from
531
which ``bzr selftest`` was run. (Martin Pool, #422350)
533
* Tests no longer fail if "close() called during concurrent
534
operation on the same file object" occurs when closing the log file
535
(which can happen if a thread tries to write to the log file at the
536
wrong moment). An warning will be written to ``stderr`` when this
537
happens, and another warning will be written if the log file could not
538
be closed after retrying 100 times. (Andrew Bennetts, #531746)
543
:2.1.2: NOT RELEASED YET
548
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
549
(Aaron Bentley, #559436)
551
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
553
(Andrew Bennetts, #528041)
555
* Reset ``siginterrupt`` flag to False every time we handle a signal
556
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
557
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
558
errors after two window resizes.
564
* ``_remember_remote_is_before`` no longer raises AssertionError when
565
suboptimal network behaviour is noticed; instead it just mutters to the
566
log file (and warns the user if they have set the ``hpss`` debug flag).
567
This was causing unnecessary aborts for performance bugs that are minor
569
(Andrew Bennetts, #528041)
577
This is a small bugfix release. Upgrading is recommended for anyone
578
running 2.1.0 or earlier.
583
* Allow syscalls to automatically restart when ``TextUIFactory``'s
584
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
585
IO, which are often poorly handled by Python's libraries and parts of
586
bzrlib. (Andrew Bennetts, #496813)
588
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
589
(Martin Pool, #331095)
591
* Fix plugin packaging on Windows. (Ian Clatworthy, #524162)
593
* Fix stub sftp test server to call os.getcwdu().
594
(Vincent Ladeuil, #526221, #526353)
596
* Fixed CHM generation by moving the NEWS section template into
597
a separate file. (Ian Clatworthy, #524184)
599
* Merge correctly when this_tree is not a WorkingTree. (Aaron Bentley)
601
* Register SIGWINCH handler only when creating a ``TextUIFactory``; avoids
602
problems importing bzrlib from a non-main thread.
603
(Elliot Murphy, #521989)
605
* Repositories accessed via a smart server now reject being stacked on a
606
repository in an incompatible format, as is the case when accessing them
607
via other methods. This was causing fetches from those repositories via
608
a smart server (e.g. using ``bzr branch``) to receive invalid data.
609
(Andrew Bennetts, #562380)
611
* Standardize the error handling when creating a new ``StaticTuple``
612
(problems will raise TypeError). (Matt Nordhoff, #457979)
614
* Warn if pyrex is too old to compile the new ``SimpleSet`` and
615
``StaticTuple`` extensions, rather than having the build fail randomly.
616
(John Arbash Meinel, #449776)
621
* Added a link to the Desktop Guide. (Ian Clatworthy)
623
* Added What's New in Bazaar 2.1 document. (Ian Clatworthy)
625
* Drop Google Analytics from the core docs as they caused problems
626
in the CHM files. (Ian Clatworthy, #502010)
631
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
632
can set a signal handler and call ``signal.siginterrupt(signum,
633
False)`` for it, if the platform and Python version supports it.

:Codename: Strasbourg
643
This release marks our second long-term-stable series. The Bazaar team
644
has decided that we will continue to make bugfix-only 2.0.x and 2.1.x
645
releases, along with 2.2 development releases.
647
This is a fairly incremental update, focusing on polish and bugfixing.
648
There are no changes for supported disk formats. Key updates include
649
reduced memory consumption for many operations, a new per-file merge
650
hook, ignore patterns can now include '!' to exclude files, globbing
651
support for all commands on Windows, and support for addressing home
652
directories via ``bzr+ssh://host/~/`` syntax.
654
Users are encouraged to upgrade from the 2.0 stable series.
659
* Don't require testtools to use sftp.
660
(Vincent Ladeuil, #516183)
662
* Fix "AttributeError in Inter1and2Helper" during fetch.
663
(Martin Pool, #513432)
665
* ``bzr update`` performs the two merges in a more logical order and will stop
666
when it encounters conflicts.
667
(Gerard Krol, #113809)
669
* Give a better error message when doing ``bzr bind`` in an already bound
670
branch. (Neil Martinsen-Burrell, #513063)
672
* Ignore ``KeyError`` from ``remove_index`` during ``_abort_write_group``
673
in a pack repository, which can happen harmlessly if the abort occurs during
674
finishing the write group. Also use ``bzrlib.cleanup`` so that any
675
other errors that occur while aborting the individual packs won't be
676
hidden by secondary failures when removing the corresponding indices.
677
(Andrew Bennetts, #423015)
679
* Set the mtime of files exported to a directory by ``bzr export`` all to
680
the same value to avoid confusing ``make`` and other date-based build
681
systems. (Robert Collins, #515631)
686
* Fetching into experimental formats will now print a warning. (Jelmer
692
* ``Repository.deserialise_inventory`` has been renamed to
693
``Repository._deserialise_inventory`` to indicate it is private.
696
* ``Repository.get_inventory_xml`` has been renamed to
697
``Repository._get_inventory_xml`` to indicate it is private.
700
* ``Repository.serialise_inventory`` has been renamed to
701
``Repository._serialise_inventory`` to indicate it is private.
703
* Using the ``bzrlib.chk_map`` module from within multiple threads at the
704
same time was broken due to race conditions with a module level page
705
cache. This shows up as a KeyError in the ``bzrlib.lru_cache`` code with
706
``bzrlib.chk_map`` in the backtrace, and can be triggered without using
707
the same high level objects such as ``bzrlib.repository.Repository``
708
from different threads. chk_map now uses a thread local cache which may
709
increase memory pressure on processes using threads.
710
(Robert Collins, John Arbash Meinel, #514090)
712
* The new ``merge_file_content`` should now be ok with tests to avoid
714
(Vincent Ladeuil, #515597)
719
* Use ``bzrlib.cleanup`` rather than less robust ``try``/``finally``
720
blocks in several places in ``bzrlib.merge``. This avoids masking prior
721
errors when errors like ``ImmortalPendingDeletion`` occur during cleanup
723
(Andrew Bennetts, #517275)
728
* The ``remove_index`` method of
729
``bzrlib.repofmt.pack_repo.AggregateIndex`` no longer takes a ``pack``
730
argument. This argument was always ignored.
731
(Andrew Bennetts, #423015)
736
:Codename: after the bubbles
737
:2.1.0rc2: 2010-01-29
739
This is a quick-turn-around to update a small issue with our new per-file
740
merge hook. We expect no major changes from this to the final 2.1.0.
745
* The new ``merge_file_content`` hook point has been altered to provide a
746
better API where state for extensions can be stored rather than the
747
too-simple function based approach. This fixes a performance regression
748
where branch configuration would be parsed per-file during merge. As
749
part of this the included news_merger has been refactored into a base
750
helper class ``bzrlib.merge.ConfigurableFileMerger``.
751

:Codename: the 'new' stable
758
:2.1.0rc1: 2009-01-21
760
This is the first stable release candidate for Bazaar's 2.1 series. From
761
this point onwards, the 2.1 series will be considered stable (as the 2.0
762
series) and only bugfixes are expected to be incorporated. The dozen or so
763
bugfixes in the 2.0.4 release are also included in this release (along
764
with more than 15 more bugfixes). Some of the interesting features are
765
support for per-file merge hooks, ``bzr unshelve --preview``, support
766
for using ! in ignore files to exclude files from being ignored, a small
767
memory leak was squashed, and many ``ObjectNotLocked`` errors were fixed.
768
This looks to be a very good start for a new stable series.
774
* Add bug information to log output when available.
775
(Neil Martinsen-Burrell, Guillermo Gonzalez, #251729)
777
* Added ``merge_file_content`` hook point to ``Merger``, allowing plugins
778
to register custom merge logic, e.g. to provide smarter merging for
781
* Bazaar now includes the ``news_merge`` plugin. It is disabled by
782
default, to enable it add a ``news_merge_files`` option to your
783
configuration. Consult ``bzr help news_merge`` for more information.
786
* ``bzr branch`` now takes a ``--bind`` option. This lets you
787
branch and bind all in one command. (Ian Clatworthy)
789
* ``bzr switch`` now takes a ``--revision`` option, to allow switching to
790
a specific revision of a branch. (Daniel Watkins, #183559)
792
* ``bzr unshelve --preview`` can now be used to show how a patch on the
793
shelf would be applied to the working tree.
794
(Guilherme Salgado, #308122)
796
* ``bzr update`` now takes a ``--revision`` argument. This lets you
797
change the revision of the working tree to any revision in the
798
ancestry of the current or master branch. (Matthieu Moy, Mark Hammond,
801
* ``-Dbytes`` can now be used to display the total number of bytes
802
transferred for the current command. This information is always logged
803
to ``.bzr.log`` for later inspection. (John Arbash Meinel)
805
* New ignore patterns. Patterns prefixed with '!' are exceptions to
806
ignore patterns and take precedence over regular ignores. Such
807
exceptions are used to specify files that should be versioned which
808
would otherwise be ignored. Patterns prefixed with '!!' act as regular
809
ignore patterns, but have highest precedence, even over the '!'
810
exception patterns. (John Whitley, #428031)
812
* The ``supress_warnings`` configuration option has been introduced to disable
813
various warnings (it currently only supports the ``format_deprecation``
814
warning). The new option can be set in any of the following locations:
815
``bazaar.conf``, ``locations.conf`` and/or ``branch.conf``.
816
(Ted Gould, Matthew Fuller, Vincent Ladeuil)
821
* Always show a message if an OS error occurs while trying to run a
822
user-specified commit message editor.
823
(Martin Pool, #504842)
825
* ``bzr diff`` will now use the epoch when it is unable to determine
826
the timestamp of a file, if the revision it was introduced in is a
827
ghost. (Jelmer Vernooij, #295611)
829
* ``bzr switch -b`` can now create branches that are located using directory
830
services such as ``lp:``, even when the branch name doesn't contain a
831
'/'. (Neil Martinsen-Burrell, #495263)
833
* ``bzr unshelve`` has improved messages about what it is doing.
834
(Neil Martinsen-Burrell, #496917)
836
* Concurrent autopacking is more resilient to already-renamed pack files.
837
If we find that a file we are about to obsolete is already obsoleted, we
838
do not try to rename it, and we leave the file in ``obsolete_packs``.
839
The code is also fault tolerant if a file goes missing, assuming that
840
another process already removed the file.
841
(John Arbash Meinel, Gareth White, #507557)
843
* Fix "Too many concurrent requests" in reconcile when network connection
844
fails. (Andrew Bennetts, #503878)
846
* Fixed a side effect mutation of ``RemoteBzrDirFormat._network_name``
847
that caused some tests to fail when run in a non-default order.
848
Probably no user impact. (Martin Pool, #504102)
850
* Fixed ``ObjectNotLocked`` error in ``bzr cat -rbranch:../foo FILE``.
851
(Andrew Bennetts, #506274)
853
* FTP transports support Unicode paths by encoding/decoding them as utf8.
854
(Vincent Ladeuil, #472161)
856
* Listen to the SIGWINCH signal to update the terminal width.
857
(Vincent Ladeuil, #316357)
859
* Progress bars are now hidden when ``--quiet`` is given.
860
(Martin Pool, #320035)
862
* ``SilentUIFactory`` now supports ``make_output_stream`` and discards
863
whatever is written to it. This un-breaks some plugin tests that
864
depended on this behaviour.
865
(Martin Pool, #499757)
867
* When operations update the working tree, all affected files should end
868
up with the same mtime. (eg. when versioning a generated file, if you
869
update the source and the generated file together, the generated file
870
should appear up-to-date.)
871
(John Arbash Meinel, Martin <gzlist>, #488724)
876
* Added ``add_cleanup`` and ``cleanup_now`` to ``bzrlib.command.Command``.
877
All the builtin commands now use ``add_cleanup`` rather than
878
``try``/``finally`` blocks where applicable as it is simpler and more
879
robust. (Andrew Bennetts)
881
* All except a small number of storage formats are now hidden, making
882
the help for numerous commands far more digestible. (Ian Clatworthy)
884
* Attempts to open a shared repository as a branch (e.g. ``bzr branch
885
path/to/repo``) will now include "location is a repository" as a hint in
886
the error message. (Brian de Alwis, Andrew Bennetts, #440952)
888
* Push will now inform the user when they are trying to push to a foreign
889
VCS for which roundtripping is not supported, and will suggest them to
890
use dpush. (Jelmer Vernooij)
892
* The version of bzr being run is now written to the log file.
895
* Transport network activity indicator is shown more of the time when
896
Bazaar is doing network IO.
902
* Add documentation on creating merges with more than one parent.
903
(Neil Martinsen-Burrell, #481526)
905
* Better explain the --uncommitted option of merge.
906
(Neil Martinsen-Burrell, #505088)
908
* Improve discussion of pending merges in the documentation for
909
``revert``. (Neil Martinsen-Burrell, #505093)
911
* Improved help for ``bzr send``.
912
(Martin Pool, Bojan Nikolic)
914
* There is a System Administrator's Guide in ``doc/en/admin-guide``,
915
including discussions of installation, relevant plugins, security and
916
backup. (Neil Martinsen-Burrell)
918
* The ``conflicts`` help topic has been renamed to ``conflict-types``.
921
* The User Reference is now presented as a series of topics.
922
Many of the included topics have link and format tweaks applied.
928
* Added ``cachedproperty`` decorator to ``bzrlib.decorators``.
931
* Many test features were renamed from ``FooFeature`` to ``foo_feature``
932
to be consistent with instances being lower case and classes being
933
CamelCase. For the features that were more likely to be used, we added a
934
deprecation thunk, but not all. (John Arbash Meinel)
936
* Merger classes (such as ``Merge3Merger``) now expect a ``this_branch``
937
parameter in their constructors, and provide ``this_branch`` as an
938
attribute. (Andrew Bennetts)
940
* The Branch hooks pre_change_branch_tip no longer masks exceptions raised
941
by plugins - the original exceptions are now preserved. (Robert Collins)
943
* The Transport ``Server.tearDown`` method is now renamed to
944
``stop_server`` and ``setUp`` to ``start_server`` for consistency with
945
our normal naming pattern, and to avoid confusion with Python's
946
``TestCase.tearDown``. (Martin Pool)
948
* ``WorkingTree.update`` implementations must now accept a ``revision``
954
* Added ``BzrDir.open_branchV3`` smart server request, which can receive
955
a string of details (such as "location is a repository") as part of a
956
``nobranch`` response. (Andrew Bennetts, #440952)
958
* New helper osutils.UnicodeOrBytesToBytesWriter which encodes unicode
959
objects but passes str objects straight through. This is used for
960
selftest but may be useful for diff and other operations that generate
961
mixed output. (Robert Collins)
963
* New exception ``NoRoundtrippingSupport``, for use by foreign branch
964
plugins. (Jelmer Vernooij)
969
* ``bzrlib.tests.permute_for_extension`` is a helper that simplifies
970
running all tests in the current module, once against a pure python
971
implementation, and once against an extension (pyrex/C) implementation.
972
It can be used to dramatically simplify the implementation of
973
``load_tests``. (John Arbash Meinel)
975
* ``bzrlib.tests.TestCase`` now subclasses ``testtools.testcase.TestCase``.
976
This permits features in testtools such as getUniqueInteger and
977
getUniqueString to be used. Because of this, testtools version 0.9.2 or
978
newer is now a dependency to run bzr selftest. Running with versions of
979
testtools less than 0.9.2 will cause bzr to error while loading the test
980
suite. (Robert Collins)
982
* Shell-like tests now support the command "mv" for moving files. The
983
syntax for ``mv file1 file2``, ``mv dir1 dir2`` and ``mv file dir`` is
984
supported. (Neil Martinsen-Burrell)
986
* The test progress bar no longer distinguishes tests that 'errored' from
987
tests that 'failed' - they're all just failures.
993
:2.0.6: NOT RELEASED YET
998
* Additional merges after an unrelated branch has been merged with its
999
history no longer crash when deleted files are involved.
1000
(Vincent Ladeuil, John Arbash Meinel, #375898)
1002
* ``bzr revert`` now only takes write lock on working tree, instead of on
1003
both working tree and branch.
1004
(Danny van Heumen, #498409)
1006
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
1007
permissions as ``.bzr`` directory on a POSIX OS.
1008
(Parth Malwankar, #262450)
1010
* Repositories accessed via a smart server now reject being stacked on a
1011
repository in an incompatible format, as is the case when accessing them
1012
via other methods. This was causing fetches from those repositories via
1013
a smart server (e.g. using ``bzr branch``) to receive invalid data.
1014
(Andrew Bennetts, #562380)
1021
This fifth release in our 2.0 series addresses several user-inconvenience
1022
bugs. None are critical, but upgrading is recommended for all users on
1023
earlier 2.0 releases.
1028
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1029
(Martin Pool, #331095)
1031
* Concurrent autopacking is more resilient to already-renamed pack files.
1032
If we find that a file we are about to obsolete is already obsoleted, we
1033
do not try to rename it, and we leave the file in ``obsolete_packs``.
1034
The code is also fault tolerant if a file goes missing, assuming that
1035
another process already removed the file.
1036
(John Arbash Meinel, Gareth White, #507557)
1038
* Cope with the lockdir ``held/info`` file being empty, which seems to
1039
happen fairly often if the process is suddenly interrupted while taking
1041
(Martin Pool, #185103)
1043
* Give the warning about potentially slow cross-format fetches much
1044
earlier on in the fetch operation. Don't show this message during
1045
upgrades, and show the correct format indication for remote
1047
(Martin Pool, #456077, #515356, #513157)
1049
* Handle renames correctly when there are files or directories that
1050
differ only in case. (Chris Jones, Martin Pool, #368931)
1052
* If ``bzr push --create-prefix`` triggers an unexpected ``NoSuchFile``
1053
error, report that error rather than failing with an unhelpful
1054
``UnboundLocalError``.
1055
(Andrew Bennetts, #423563)
1057
* Running ``bzr`` command without any arguments now shows bzr
1058
version number along with rest of the help text.
1059
(Parth Malwankar, #369501)
1061
* Use osutils.O_NOINHERIT for some files on win32 to avoid PermissionDenied
1063
(Inada Naoki, #524560)
1068
* Added ``location-alias`` help topic.
1069
(Andrew Bennetts, #337834)
1071
* Fixed CHM generation by moving the NEWS section template into
1072
a separate file. (Ian Clatworthy, #524184)
1078
:Codename: smooth sailing
1081
The fourth bugfix-only release in the 2.0 series contains more than a
1082
dozen bugfixes relative to 2.0.3. The primary focus is on handling
1083
interruptions and concurrent operations more cleanly, there is also a fair
1084
improvement to ``bzr export`` when exporting a remote branch.
1090
* ``bzr annotate`` on another branch with ``-r branch:...`` no longer
1091
fails with an ``ObjectNotLocked`` error. (Andrew Bennetts, #496590)
1093
* ``bzr export dir`` now requests all file content as a record stream,
1094
rather than requsting the file content one file-at-a-time. This can make
1095
exporting over the network significantly faster (54min => 9min in one
1096
case). (John Arbash Meinel, #343218)
1098
* ``bzr serve`` no longer slowly leaks memory. The compiled
1099
``bzrlib.bencode.Encoder()`` class was using ``__del__`` to cleanup and
1100
free resources, and it should have been using ``__dealloc__``.
1101
This will likely have an impact on any other process that is serving for
1102
an extended period of time. (John Arbash Meinel, #494406)
1104
* Check for SIGINT (Ctrl-C) and other signals immediately if ``readdir``
1105
returns ``EINTR`` by calling ``PyErr_CheckSignals``. This affected the
1106
optional ``_readdir_pyx`` extension. (Andrew Bennetts, #495023)
1108
* Concurrent autopacks will no longer lose a newly created pack file.
1109
There was a race condition, where if the reload happened at the right
1110
time, the second packer would forget the name of the newly added pack
1111
file. (John Arbash Meinel, Gareth White, #507566)
1113
* Give a clearer message if the lockdir disappears after being apparently
1114
successfully taken. (Martin Pool, #498378)
1116
* Give a warning when fetching between repositories (local or remote) with
1117
sufficiently different formats that the content will need to be
1118
serialized (ie ``InterDifferingSerializer`` or ``inventory-deltas``), so
1119
the user has a clue that upgrading could make it faster.
1120
(Martin Pool, #456077)
1122
* If we fail to open ``~/.bzr.log`` write a clear message to stderr rather
1123
than using ``warning()``. The log file is opened before logging is set
1124
up, and it leads to very confusing: 'no handlers for "bzr"' messages for
1125
users, rather than something nicer.
1126
(John Arbash Meinel, Barry Warsaw, #503886)
1128
* Refuse to build with any Pyrex 0.9.4 release, as they have known bugs.
1129
(Martin Pool, John Arbash Meinel, #449372)
1131
* ``setup.py bdist_rpm`` now properly finds extra files needed for the
1132
build. (there is still the distutils bug
1133
http://bugs.python.org/issue644744) (Joe Julian, #175839)
1135
* The 2a format wasn't properly restarting autopacks when something
1136
changed underneath it (like another autopack). Now concurrent
1137
autopackers will properly succeed. (John Arbash Meinel, #495000)
1139
* ``TreeTransform`` can now handle when a delta says that the file id for
1140
the tree root changes. Rather than trying to rename your working
1141
directory, or failing early saying that you can't have multiple
1142
tree roots. This also fixes revert, update, and pull when the root id
1143
changes. (John Arbash Meinel, #494269, #504390)
1145
* ``_update_current_block`` no longer suppresses exceptions, so ^C at just
1146
the right time will get propagated, rather than silently failing to move
1147
the block pointer. (John Arbash Meinel, Gareth White, #495023)
1152
* We have a new ``test_source`` that ensures all pyrex ``cdef`` functions
1153
handle exceptions somehow. (Possibly by setting ``# cannot_raise``
1154
rather than an ``except ?:`` clause.) This should help prevent bugs like
1155
bug #495023. (John Arbash Meinel)

:2.1.0b4: 2009-12-14
1164
The fourth beta release in the 2.1 series brings with it a significant
1165
number of bugfixes (~20). The test suite is once again (finally) "green"
1166
on Windows, and should remain that way for future releases. There are a
1167
few performance related updates (faster upgrade and log), and several UI
1168
tweaks. There has also been a significant number of tweaks to the runtime
1169
documentation. 2.1.0b4 include everything from the 2.0.3 release.
1172
Compatibility Breaks
1173
********************
1175
* The BZR_SSH environmental variable may now be set to the path of a secure
1176
shell client. If currently set to the value ``ssh`` it will now guess the
1177
vendor of the program with that name, to restore the old behaviour that
1178
indicated the SSH Corporation client use ``sshcorp`` instead as the magic
1179
string. (Martin <gzlist@googlemail.com>, #176292)
1184
* ``bzr commit`` now has a ``--commit-time`` option.
1185
(Alexander Sack, #459276)
1187
* ``-Dhpss`` now increases logging done when run on the bzr server,
1188
similarly to how it works on the client. (John Arbash Meinel)
1190
* New option ``bzr unshelve --keep`` applies the changes and leaves them
1191
on the shelf. (Martin Pool, Oscar Fuentes, #492091)
1193
* The ``BZR_COLUMNS`` envrionment variable can be set to force bzr to
1194
respect a given terminal width. This can be useful when output is
1195
redirected or in obscure cases where the default value is not
1196
appropriate. Pagers can use it to get a better control of the line
1200
* The new command ``bzr lp-mirror`` will request that Launchpad update its
1201
mirror of a local branch. This command will only function if launchpadlib
1209
* After renaming a file, the dirstate could accidentally reference
1210
``source\\path`` rather than ``source/path`` on Windows. This might be a
1211
source of some dirstate-related failures. (John Arbash Meinel)
1213
* ``bzr commit`` now detects commit messages that looks like file names
1214
and issues a warning.
1215
(Gioele Barabucci, #73073)
1217
* ``bzr ignore /`` no longer causes an IndexError. (Gorden Tyler, #456036)
1219
* ``bzr log -n0 -rN`` should not return revisions beyond its merged revisions.
1220
(#325618, #484109, Marius Kruger)
1222
* ``bzr merge --weave`` and ``--lca`` will now create ``.BASE`` files for
1223
files with conflicts (similar to ``--merge3``). The contents of the file
1224
is a synthesis of all bases used for the merge.
1225
(John Arbash Meinel, #40412)
1227
* ``bzr mv --quiet`` really is quiet now. (Gordon Tyler, #271790)
1229
* ``bzr serve`` is more clear about the risk of supplying --allow-writes.
1230
(Robert Collins, #84659)
1232
* ``bzr serve --quiet`` really is quiet now. (Gordon Tyler, #252834)
1234
* Fix bug with redirected URLs over authenticated HTTP.
1235
(Glen Mailer, Neil Martinsen-Burrell, Vincent Ladeuil, #395714)
1237
* Interactive merge doesn't leave branch locks behind. (Aaron Bentley)
1239
* Lots of bugfixes for the test suite on Windows. We should once again
1240
have a test suite with no failures on Windows. (John Arbash Meinel)
1242
* ``osutils.terminal_width()`` obeys the BZR_COLUMNS environment
1243
variable but returns None if the terminal is not a tty (when output is
1244
redirected for example). Also fixes its usage under OSes that doesn't
1245
provide termios.TIOCGWINSZ. Make sure the corresponding tests runs on
1247
(Joke de Buhr, Vincent Ladeuil, #353370, #62539)
1248
(John Arbash Meinel, Vincent Ladeuil, #492561)
1250
* Terminate ssh subprocesses when no references to them remain, fixing
1251
subprocess and file descriptor leaks. (Andrew Bennetts, #426662)
1253
* The ``--hardlink`` option of ``bzr branch`` and ``bzr checkout`` now
1254
works for 2a format trees. Only files unaffected by content filters
1255
will be hardlinked. (Andrew Bennetts, #408193)
1257
* The new glob expansion on Windows would replace all ``\`` characters
1258
with ``/`` even if it there wasn't a glob to expand, the arg was quoted,
1259
etc. Now only change slashes if there is something being glob expanded.
1260
(John Arbash Meinel, #485771)
1262
* Use our faster ``KnownGraph.heads()`` functionality when computing the
1263
new rich-root heads. This can cut a conversion time in half (mysql from
1264
13.5h => 6.2h) (John Arbash Meinel, #487632)
1266
* When launching a external diff tool via bzr diff --using, temporary files
1267
are no longer created, rather, the path to the file in the working tree is
1268
passed to the external diff tool. This allows the file to be edited if the
1269
diff tool provides for this. (Gary van der Merwe, #490738)
1271
* The launchpad-open command can now be used from a subdirectory of a
1272
branch, not just from the root of the branch.
1273
(Neil Martinsen-Burrell, #489102)
1279
* ``bzr log`` is now faster. (Ian Clatworthy)
1281
* ``bzr update`` provides feedback on which branch it is up to date with.
1282
(Neil Martinsen-Burrell)
1284
* ``bzr upgrade`` from pre-2a to 2a can be significantly faster (4x).
1285
For details see the xml8 patch and heads() improvements.
1286
(John Arbash Meinel)
1288
* ``bzrlib.urlutils.local_path_from_url`` now accepts
1289
'file://localhost/' as well as 'file:///' URLs on POSIX. (Michael
1292
* The progress bar now shows only a spinner and per-operation counts,
1293
not an overall progress bar. The previous bar was often not correlated
1294
with real overall operation progress, either because the operations take
1295
nonlinear time, or because at the start of the operation Bazaar couldn't
1296
estimate how much work there was to do. (Martin Pool)
1301
* Lots of documentation tweaks for inline help topics and command help
1307
* ``bzrlib.textui`` (vestigial module) removed. (Martin Pool)
1309
* The Launchpad plugin now has a function ``login`` which will log in to
1310
Launchpad with launchpadlib, and ``load_branch`` which will return the
1311
Launchpad Branch object corresponding to a given Bazaar Branch object.
1317
* New test Feature: ``ModuleAvailableFeature``. It is designed to make it
1318
easier to handle what tests you want to run based on what modules can be
1319
imported. (Rather than lots of custom-implemented features that were
1320
basically copy-and-pasted.) (John Arbash Meinel)
1322
* ``osutils.timer_func()`` can be used to get either ``time.time()`` or
1323
``time.clock()`` when you want to do performance timing.
1324
``time.time()`` is limited to 15ms resolution on Windows, but
1325
``time.clock()`` gives CPU and not wall-clock time on other platforms.
1326
(John Arbash Meinel)
1328
* Several code paths that were calling ``Transport.get().read()`` have
1329
been changed to the equalivent ``Transport.get_bytes()``. The main
1330
difference is that the latter will explicitly call ``file.close()``,
1331
rather than expecting the garbage collector to handle it. This helps
1332
with some race conditions on Windows during the test suite and sftp
1333
tests. (John Arbash Meinel)
1338
* TestCaseWithMemoryTransport no longer sets $HOME and $BZR_HOME to
1339
unicode strings. (Michael Hudson, #464174)
1345
:Codename: little italy
1349
The third stable release of Bazaar has a small handful of bugfixes. As
1350
expected, this has no internal or external compatibility changes versus
1356
* ``bzr push --use-existing-dir`` no longer crashes if the directory
1357
exists but contains an invalid ``.bzr`` directory.
1358
(Andrew Bennetts, #423563)
1360
* Content filters are now applied correctly after pull, merge and switch.
1361
(Ian Clatworthy, #385879)
1363
* Fix a potential segfault in the groupcompress hash map handling code.
1364
When inserting new entries, if the final hash bucket was empty, we could
1365
end up trying to access if ``(last_entry+1)->ptr == NULL``.
1366
(John Arbash Meinel, #490228)
1368
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
1374
:Codename: after sprint recovery
1375
:2.1.0b3: 2009-11-16
1377
This release was pushed up from its normal release cycle due to a
1378
regression in python 2.4 compatibility in 2.1.0b2. Since this regression
1379
was caught before 2.1.0b2 was officially announced, the full changelog
1380
includes both 2.1.0b3 and 2.1.0b2 changes.
1382
Highlights of 2.1.0b3 are: new globbing code for all commands on Windows,
1383
the test suite now conforms to python's trunk enhanced semantics (skip,
1384
etc.), and ``bzr info -v`` will now report the correct branch and repo
1385
formats for Remote objects.
1391
* Users can define a shelve editor to provide shelf functionality at a
1392
granularity finer than per-patch-hunk. (Aaron Bentley)
1397
* Fix for shell completion and short options. (Benoît PIERRE)
1399
* Fix ``bzr --profile-imports`` with Python 2.6. (Martin Pool)
1401
* Hooks daughter classes should always call the base constructor.
1402
(Alexander Belchenko, Vincent Ladeuil, #389648)
1404
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
1406
* On Windows, do glob expansion at the command-line level (as is usually
1407
done in bash, etc.) This means that *all* commands get glob expansion
1408
(bzr status, bzr add, bzr mv, etc). It uses a custom command line
1409
parser, which allows us to know if a given section was quoted. It means
1410
you can now do ``bzr ignore "*.py"``.
1411
(John Arbash Meinel, #425510, #426410, #194450)
1413
* Sanitize commit messages that come in from the '-m' flag. We translate
1414
'\r\n' => '\n' and a plain '\r' => '\n'. The storage layer doesn't
1415
allow those because XML store silently translate it anyway. (The parser
1416
auto-translates \r\n => \n in ways that are hard for us to catch.)
1418
* Show correct branch and repository format descriptions in
1419
``bzr info -v`` on a smart server location. (Andrew Bennetts, #196080)
1421
* The fix for bug #186920 accidentally broke compatibility with python
1422
2.4. (Vincent Ladeuil, #475585)
1424
* Using ``Repository.get_commit_builder().record_iter_changes()`` now
1425
correctly sets ``self.inv_sha1`` to a sha1 string and
1426
``self.new_inventory`` to an Inventory instance after calling
1427
``self.finish_inventory()``. (Previously it accidently set both values
1428
as a tuple on ``self.inv_sha1``. This was missed because
1429
``repo.add_revision`` ignores the supplied inventory sha1 and recomputes
1430
the sha1 from the repo directly. (John Arbash Meinel)
1432
* Shelve command refuse to run if there is no real terminal.
1433
(Alexander Belchenko)
1435
* Avoid unnecessarily flushing of trace file; it's now unbuffered at the
1436
Python level. (Martin Pool)
1441
* Include Japanese translations for documentation (Inada Naoki)
1443
* New API ``ui_factory.make_output_stream`` to be used for sending bulk
1444
(rather than user-interaction) data to stdout. This automatically
1445
coordinates with progress bars or other terminal activity, and can be
1447
(Martin Pool, 493944)
1452
* Some of the core groupcompress functionality now releases the GIL before
1453
operation. Similar to how zlib and bz2 operate without the GIL in the
1454
core compression and decompression routines. (John Arbash Meinel)
1459
* -Dhpssvfs will now trigger on ``RemoteBzrDir._ensure_real``, providing
1460
more debugging of VFS access triggers. (Robert Collins)
1462
* KnownFailure is now signalled to ``ExtendedTestResult`` using the same
1463
method that Python 2.7 uses - ``addExpectedFailure``. (Robert Collins)
1465
* ``--parallel=fork`` is now compatible with --subunit.
1466
(Robert Collins, Vincent Ladeuil, #419776)
1468
* Reporting of failures shows test ids not descriptions and thus shows
1469
parameterised tests correctly. (Robert Collins)
1471
* TestNotApplicable is now handled within the TestCase.run method rather
1472
than being looked for within ``ExtendedTestResult.addError``. This
1473
provides better handling with other ``TestResult`` objects, degrading to
1474
sucess rather than error. (Robert Collins)
1476
* The private method ``_testConcluded`` on ``ExtendedTestResult`` has been
1477
removed - it was empty and unused. (Robert Collins)
1479
* UnavailableFeature is now handled within the TestCase.run method rather
1480
than being looked for within addError. If the Result object does not
1481
have an addNotSupported method, addSkip is attempted instead, and
1482
failing that addSuccess. (Robert Collins)
1484
* When a TestResult does not have an addSkip method, skipped tests are now
1485
reported as successful tests, rather than as errors. This change is
1486
to make it possible to get a clean test run with a less capable
1487
TestResult. (Robert Collins)
1494
:Codename: a load off my mind
1495
:2.1.0b2: 2009-11-02
1497
This is our second feature-filled release since 2.0, pushing us down the
1498
path to a 2.1.0. Once again, all bugfixes in 2.0.2 are present in 2.1.0b2.
1500
Key highlights in this release are: improved handling of
1501
failures-during-cleanup for commit, fixing a long-standing bug with
1502
``bzr+http`` and shared repositories, all ``lp:`` urls to be resolved
1503
behind proxies, and a new StaticTuple datatype, allowing us to reduce
1504
memory consumption (50%) and garbage collector overhead (40% faster) for
1507
* A new ``--concurrency`` option has been added as well as an associated
1508
BZR_CONCURRENCY environment variable to specify the number of
1509
processes that can be run concurrently when running ``bzr selftest``. The
1510
command-line option overrides the environment variable if both are
1511
specified. If none is specified. the number of processes is obtained
1512
from the OS as before. (Matt Nordhoff, Vincent Ladeuil)
1517
* ``bzr+http`` servers no longer give spurious jail break errors when
1518
serving branches inside a shared repository. (Andrew Bennetts, #348308)
1520
* Errors during commit are handled more robustly so that knock-on errors
1521
are less likely to occur, and will not obscure the original error if
1522
they do occur. This fixes some causes of ``TooManyConcurrentRequests``
1523
and similar errors. (Andrew Bennetts, #429747, #243391)
1525
* Launchpad urls can now be resolved from behind proxies.
1526
(Gordon Tyler, Vincent Ladeuil, #186920)
1528
* Reduce the strictness for StaticTuple, instead add a debug flag
1529
``-Dstatic_tuple`` which will change apis to be strict and raise errors.
1530
This way, most users won't see failures, but developers can improve
1531
internals. (John Arbash Meinel, #471193)
1533
* TreeTransform.adjust_path updates the limbo paths of descendants of adjusted
1534
files. (Aaron Bentley)
1536
* Unicode paths are now handled correctly and consistently by the smart
1537
server. (Andrew Bennetts, Michael Hudson, #458762)
1542
* When reading index files, we now use a ``StaticTuple`` rather than a
1543
plain ``tuple`` object. This generally gives a 20% decrease in peak
1544
memory, and can give a performance boost up to 40% on large projects.
1545
(John Arbash Meinel)
1547
* Peak memory under certain operations has been reduced significantly.
1548
(eg, 'bzr branch launchpad standalone' is cut in half)
1549
(John Arbash Meinel)
1554
* Filtered views user documentation upgraded to refer to format 2a
1555
instead of pre-2.0 formats. (Ian Clatworthy)
1560
* Remove deprecated ``CLIUIFactory``. (Martin Pool)
1562
* ``UIFactory`` now has new ``show_error``, ``show_message`` and
1563
``show_warning`` methods, which can be hooked by non-text UIs.
1569
* Added ``bzrlib._simple_set_pyx``. This is a hybrid between a Set and a
1570
Dict (it only holds keys, but you can lookup the object located at a
1571
given key). It has significantly reduced memory consumption versus the
1572
builtin objects (1/2 the size of Set, 1/3rd the size of Dict). This is
1573
used as the interning structure for StaticTuple objects.
1574
(John Arbash Meinel)
1576
* ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
1577
the btree index parser and the chk map parser. This class functions
1578
similarly to ``tuple`` objects. However, it can only point to a limited
1579
collection of types. (Currently StaticTuple, str, unicode, None, bool,
1580
int, long, float, but not subclasses). This allows us to remove it from
1581
the garbage collector (it cannot be in a cycle), it also allows us to
1582
intern the objects. In testing, this can reduce peak memory by 20-40%,
1583
and significantly improve performance by removing objects from being
1584
inspected by the garbage collector. (John Arbash Meinel)
1586
* ``GroupCompressBlock._ensure_content()`` will now release the
1587
``zlib.decompressobj()`` when the first request is for all of the
1588
content. (Previously it would only be released if you made a request for
1589
part of the content, and then all of it later.) This turns out to be a
1590
significant memory savings, as a ``zstream`` carries around approx 260kB
1591
of internal state and buffers. (For branching bzr.dev this drops peak
1592
memory from 382MB => 345MB.) (John Arbash Meinel)
1594
* When streaming content between ``2a`` format repositories, we now clear
1595
caches from earlier versioned files. (So 'revisions' is cleared when we
1596
start reading 'inventories', etc.) This can have a significant impact on
1597
peak memory for initial copies (~200MB). (John Arbash Meinel)
1603
:Codename: after the scare
1606
The second in our "let's keep the stable bugfixes flowing" series. As
1607
expected this has a few (~9) bugfixes relative to 2.0.1, and no major api
1608
changes or features.
1613
* Avoid "NoneType has no attribute st_mode" error when files disappear
1614
from a directory while it's being read. (Martin Pool, #446033)
1616
* Content filters are now applied correctly after revert.
1619
* Diff parsing handles "Binary files differ" hunks. (Aaron Bentley, #436325)
1621
* Fetching from stacked pre-2a repository via a smart server no longer
1622
fails intermittently with "second push failed to complete".
1623
(Andrew Bennetts, #437626)
1625
* Fix typos left after test_selftest refactoring.
1626
(Vincent Ladeuil, Matt Nordhoff, #461149)
1628
* Fixed ``ObjectNotLocked`` errors during ``bzr log -r NNN somefile``.
1629
(Andrew Bennetts, #445171)
1631
* PreviewTree file names are not limited by the encoding of the temp
1632
directory's filesystem. (Aaron Bentley, #436794)
1637
* ``bzr log`` now read-locks branches exactly once, so makes better use of
1638
data caches. (Andrew Bennetts)
1643
* Filtered views user documentation upgraded to refer to format 2a
1644
instead of pre-2.0 formats. (Ian Clatworthy)

:Codename: While the cat is away
1651
:2.1.0b1: 2009-10-14
1653
This is the first development release in the new split "stable" and
1654
"development" series. As such, the release is a snapshot of bzr.dev
1655
without creating a release candidate first. This release includes a
1656
fair amount of internal changes, with deprecated code being removed,
1657
and several new feature developments. People looking for a stable code
1658
base with only bugfixes should focus on the 2.0.1 release. All bugfixes
1659
present in 2.0.1 are present in 2.1.0b1.
1661
Highlights include support for ``bzr+ssh://host/~/homedir`` style urls,
1662
finer control over the plugin search path via extended BZR_PLUGIN_PATH
1663
syntax, visible warnings when extension modules fail to load, and improved
1664
error handling during unlocking.
