: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
102
* ``_remember_remote_is_before`` no longer raises AssertionError when
103
suboptimal network behaviour is noticed; instead it just mutters to the
104
log file (and warns the user if they have set the ``hpss`` debug flag).
105
This was causing unnecessary aborts for performance bugs that are minor
107
(Andrew Bennetts, #528041)
109
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
110
files loaded from disk. To ensure docstrings needed for help are never
111
stripped, the prefix ``__doc__ =`` should now be used.
112
(Martin <gzlist@googlemail.com>)
117
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
118
(Gordon Tyler, #551332)
120
* Workaround ``Crypto.Random`` check leading to spurious test
121
failures on Lucid, FreeBSD and gentoo.
122
(Vincent Ladeuil, #528436)
129
This is a somewhat early second beta of the 2.2 series, to fix a python2.4
130
incompatibility in the 2.2b1 release. It also includes a swag of
131
performance, usability and correctness improvements: test feedback on all
132
of these would be welcome.
138
* ``bzr diff`` now supports a --format option, which can be used to
139
select alternative diff formats. (Jelmer Vernooij, #555994)
144
* ``bzr dpush``, ``bzr push`` and ``bzr send`` will now issue a warning
145
instead of failing when dirty trees are involved. The corresponding
146
``dpush_strict``, ``push_strict`` and ``send_strict`` should be set to
147
True explicitly to get the previous behaviour.
148
(Vincent Ladeuil, #519319)
150
* ``bzr export`` to tar file does not fail if any parent directory
151
contains unicode characters. This works around upstream Python bug
152
http://bugs.python.org/issue8396 .
153
(Parth Malwankar, #413406)
155
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
156
(Aaron Bentley, #559436)
158
* ``bzr update`` when a pending merge in the working tree has been merged
159
into the master branch will no longer claim that old commits have become
160
pending merges. (Robert Collins, #562079)
162
* ``bzrlib.mutabletree.MutableTree.commit`` will now support a passed in
163
config as in previous versions of bzrlib. (Robert Collins)
165
* Fix glitch in the warning about unclean trees display.
166
(Vincent Ladeuil, #562665)
168
* Fixed Python2.4 incompatibilities in the bzr2.2b1 source tarball.
171
* Help messages generated by ``RegistryOption.from_kwargs`` list the
172
switches in alphabetical order, rather than in an undefined order.
173
(Martin von Gagern, #559409)
175
* Make sure the ``ExecutablePath`` and ``InterpreterPath`` are set in
176
Apport crash reports, to avoid "This problem report applies to a program
177
which is not installed any more" error.
178
(Martin Pool, James Westby, #528114)
180
* Reset ``siginterrupt`` flag to False every time we handle a signal
181
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
182
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
183
errors after two window resizes.
186
* When invoked with a range revision, ``bzr log`` doesn't show revisions
187
that are not part of the Y revisions ancestry anymore when invoked with
189
(Vincent Ladeuil, #474807)
191
* Properly handle ``param_name`` attribute for ``ListOption``.
192
(Martin von Gagern, 387117)
197
* ``bzr commit`` will prompt before using a commit message that was
198
generated by a template and not edited by the user.
199
(Robert Collins, #530265)
201
* ``bzr diff`` read-locks the trees and branches only once, saving about
202
10-20ms on ``bzr diff`` in a bzr.dev tree.
205
* ``bzr missing`` read-locks the branches only once.
208
* ``bzr pull`` locks the branches and tree only once.
211
* Index lookups in pack repositories search recently hit pack files first.
212
In repositories with many pack files this can greatly reduce the
213
number of files accessed, the number of bytes read, and the number of
214
read calls. An incremental pull via plain HTTP takes half the time and
215
bytes for a moderately large repository. (Andrew Bennetts)
217
* Index lookups only re-order the indexes when the hit files aren't
218
already first. Reduces the cost of reordering
219
(John Arbash Meinel, #562429)
221
* Less code is loaded at startup. (Cold-cache start time is about 10-20%
223
(Martin Pool, #553017)
228
* ``bzrlib.diff.get_trees_and_branches_to_diff`` is deprecated. Use
229
``get_trees_and_branches_to_diff_locked`` instead.
235
* ``bzrlib.commands.Command.run_direct`` is no longer needed - the pre
236
2.1 method of calling run() to perform testing or direct use via the API
237
is now possible again. As part of this, the _operation attribute on
238
Command is now transient and only exists for the duration of ``run()``.
249
* BTreeGraphIndex can now take an offset to indicate that the data starts
250
somewhere other than then beginning of the file. (John Arbash Meinel)
252
* Deleted very old hidden commands ``versionedfile-list``,
253
``weave-plan-merge``, ``weave-merge-text``.
256
* ``Repository.get_inventory_sha1()`` and ``Repository.get_revision_xml()``
257
have been removed. (Jelmer Vernooij)
259
* ``Repository.get_revision_inventory()`` has been removed in favor of
260
``Repository.get_inventory()``. (Jelmer Vernooij)
262
* All test servers have been moved out of the bzrlib.transport hierarchy to
263
bzrlib.tests.test_server *except* for MemoryServer, ChrootServer and
264
PathFilteringServer. ``bzrlib`` users may encounter test failures that can
265
be fixed by updating the related imports from ``bzrlib.transport.xxx`` to
266
``bzrlib.tests.test_server``.
269
* ``BranchReferenceFormat.initialize()`` now takes an optional name argument
270
as its second parameter, for consistency with the initialize() method of
271
other formats. (Jelmer Vernooij)
276
* Added ``bzr remove-branch`` command that can remove a local or remote
277
branch. (Jelmer Vernooij, #276295)
279
* ``bzr export`` now takes an optional argument ``--per-file-timestamps``
280
to set file mtimes to the last timestamp of the last revision in which
281
they were changed rather than the current time. (Jelmer Vernooij)
283
* If the Apport crash-reporting tool is available, bzr crashes are now
284
stored into the ``/var/crash`` apport spool directory, and the user is
285
invited to report them to the developers from there, either
286
automatically or by running ``apport-bug``. No information is sent
287
without specific permission from the user. (Martin Pool, #515052)
289
* Parsing of command lines, for example in ``diff --using``, no longer
290
treats backslash as an escape character on Windows. (Gordon Tyler,
293
* Plugins can be disabled by defining ``BZR_DISABLE_PLUGINS`` as
294
a list of plugin names separated by ':' (';' on windows).
295
(Vincent Ladeuil, #411413)
297
* Plugins can be loaded from arbitrary locations by defining
298
``BZR_PLUGINS_AT`` as a list of name@path separated by ':' (';' on
299
windows). This takes precedence over ``BZR_PLUGIN_PATH`` for the
300
specified plugins. This is targeted at plugin developers for punctual
301
needs and *not* intended to replace ``BZR_PLUGIN_PATH``.
302
(Vincent Ladeuil, #82693)
304
* Tag names can now be determined automatically by ``automatic_tag_name``
305
hooks on ``Branch`` if they are not specified on the command line.
308
* Tree-shape conflicts can be resolved by providing ``--take-this`` and
309
``--take-other`` to the ``bzr resolve`` command. Just marking the conflict
310
as resolved is still accessible via the ``--done`` default action.
313
* Merges can be proposed on Launchpad with the new lp-propose-merge command.
314
(Aaron Bentley, Jonathan Lange)
319
* Added docstring for ``Tree.iter_changes``
320
(John Arbash Meinel, #304182)
322
* Allow additional arguments to
323
``RemoteRepository.add_inventory_by_delta()``. (Jelmer Vernooij, #532631)
325
* Allow exporting a single file using ``bzr export``.
326
(Michal Junák, #511987)
328
* Allow syscalls to automatically restart when ``TextUIFactory``'s
329
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
330
IO, which are often poorly handled by Python's libraries and parts of
331
bzrlib. (Andrew Bennetts, #496813)
333
* Avoid infinite recursion when probing for apport.
334
(Vincent Ladeuil, #516934)
336
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
337
(Martin Pool, #331095)
339
* Avoid truncating svn URLs.
340
(Martin Pool, Martin von Gagern, #545185)
342
* ``bzr add`` will not add conflict related files unless explicitly required.
343
(Vincent Ladeuil, #322767, #414589)
345
* ``bzr dump-btree`` now works on ``*.cix`` and ``*.six`` files. Those
346
indices do not have reference lists, so ``dump-btree`` will simply show
347
``None`` instead. (Andrew Bennetts, #488607)
349
* ``bzr help`` will no longer trigger the get_missing_command hook when
350
doing a topic lookup. This avoids prompting (like 'no command plugins/loom,
351
did you mean log?') when getting help. In future we may trigger the hook
352
deliberately when no help topics match from any help index.
353
(Robert Collins, #396261)
355
* ``bzr log -n0 -r..A.B.C`` should not crash but just consider the None
356
revspec as representing the first revision of the branch.
357
(Vincent Ladeuil, #519862)
359
* ``bzr remove-tree`` can now remove multiple working trees.
360
(Jared Hance, Andrew Bennetts, #253137)
362
* ``bzr resolve --take-this`` and ``--take-other`` now correctly renames
363
the kept file on content conflicts where one side deleted the file.
364
(Vincent Ladeuil, #529968)
366
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
367
permissions as ``.bzr`` directory on a POSIX OS.
368
(Parth Malwankar, #262450)
370
* ``bzr upgrade`` now names backup directory as ``backup.bzr.~N~`` instead
371
of ``backup.bzr``. This directory is ignored by bzr commands such as
373
(Parth Malwankar, #335033, #300001)
375
* Cope with non-utf8 characters inside ``.bzrignore``.
376
(Jason Spashett, #183504)
378
* Correctly interpret "451 Rename/move failure: Directory not empty" from
379
ftp servers while trying to take a lock.
380
(Martin Pool, #528722)
382
* DirStateRevisionTree.kind() was returning wrong result when 'kind'
383
changes occured between the workingtree and one of its parents.
384
(Vincent Ladeuil, #535547)
386
* Fix ``log`` to better check ancestors even if merged revisions are involved.
387
(Vincent Ladeuil, #476293)
389
* Loading a plugin from a given path with ``BZR_PLUGINS_AT`` doesn't depend
390
on os.lisdir() order and is now reliable.
391
(Vincent Ladeuil, #552922).
393
* Many IO operations that returned ``EINTR`` were retried even if it
394
wasn't safe to do so via careless use of ``until_no_eintr``. Bazaar now
395
only retries operations that are safe to retry, and in some cases has
396
switched to operations that can be retried (e.g. ``sock.send`` rather than
398
(Andrew Bennetts, Martin <gzlist@googlemail.com>, #496813)
400
* Path conflicts now support --take-this and --take-other even when a
401
deletion is involved.
402
(Vincent Ladeuil, #531967)
404
* Network transfer amounts and rates are now displayed in SI units according
405
to the Ubuntu Units Policy <https://wiki.ubuntu.com/UnitsPolicy>.
406
(Gordon Tyler, #514399)
408
* Support kind markers for socket and fifo filesystem objects. This
409
prevents ``bzr status --short`` from crashing when those files are
410
present. (John Arbash Meinel, #303275)
412
* ``bzr mkdir DIR`` will not create DIR unless DIR's parent is a versioned
413
directory. (Parth Malwankar, #138600)
415
* SSH child processes will now ignore SIGQUIT on nix systems so breaking into
416
the debugger won't kill the session.
417
(Martin <gzlist@googlemail.com>, #162502)
419
* Tolerate patches with leading noise in ``bzr-handle-patch``.
420
(Toshio Kuratomi, Martin Pool, #502076)
422
* ``update -r`` now supports updating to revisions that are not on
423
mainline (i.e. it supports dotted revisions).
424
(Parth Malwankar, #517800)
426
* Use first apparent author not committer in GNU Changelog format.
427
(Martin von Gagern, #513322)
432
* ``bzrlib.merge_directive._BaseMergeDirective`` has been renamed to
433
``bzrlib.merge_directive.BaseMergeDirective`` and is now public.
436
* ``BranchFormat.initialize`` now takes an optional ``name`` of the colocated
437
branch to create. (Jelmer Vernooij)
439
* ``BzrDir.get_branch_transport`` now takes an optional ``name`` of the
440
colocated branch to open. (Jelmer Vernooij)
442
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
443
can set a signal handler and call ``signal.siginterrupt(signum,
444
False)`` for it, if the platform and Python version supports it.
445
(Andrew Bennetts, #496813)
447
* New ``bzrlib.initialize`` is recommended for programs using bzrlib to
448
run when starting up; it sets up several things that previously needed
449
to be done separately.
450
(Martin Pool, #507710)
452
* Exporters now support a ``per_file_timestamps`` argument to write out the
453
timestamp of the commit in which a file revision was introduced.
456
* New method ``BzrDir.list_branches()`` that returns a sequence of branches
457
present in a control directory. (Jelmer Vernooij)
459
* New method ``Repository.get_known_graph_ancestry()``.
460
(Jelmer Vernooij, #495502)
462
* New transport methods ``readlink``, ``symlink`` and ``hardlink``.
465
* Remove unused ``CommandFailed`` exception.
471
* ``bzrlib.branchbuilder.BranchBuilder.build_snapshot`` now accepts a
472
``message_callback`` in the same way that commit does. (Robert Collins)
474
* ``bzrlib.builtins.Commit.run`` raises ``bzrlib.errors.BoundBranchOutOfDate``
475
rather than ``bzrlib.errors.BzrCommandError`` when the bound branch is out
476
of date. (Gary van der Merwe)
478
* ``bzrlib.commands.run_bzr`` is more extensible: callers can supply the
479
functions to load or disable plugins if they wish to use a different
480
plugin mechanism; the --help, --version and no-command name code paths
481
now use the generic pluggable command lookup infrastructure.
484
* ``bzrlib.errors.BoundBranchOutOfDate`` has a new field ``extra_help``
485
which can be set to add extra help to the error. (Gary van der Merwe)
487
* New method ``Branch.automatic_tag_name`` that can be used to find the
488
tag name for a particular revision automatically. (Jelmer Vernooij)
490
* The methods ``BzrDir.create_branch()``, ``BzrDir.destroy_branch()`` and
491
``BzrDir.open_branch()`` now take an optional ``name`` argument.
497
* bzr now has a ``.testr.conf`` file in its source tree configured
498
appropriately for running tests with Testrepository
499
(``https://launchpad.net/testrepository``). (Robert Collins)
501
* Documentation about testing with ``subunit`` has been tweaked.
504
* Known failures has been added for resolve --take-other on ParentLoop
505
conflicts. This reflects bug #537956 without fixing it.
508
* New ``bzrlib.tests.test_import_tariff`` can make assertions about what
509
Python modules are loaded, to guard against startup time or library
510
dependency regressions.
513
* PQM will now run with subunit output. To analyze a PQM error use
514
tribunal, or cat log | subunit-filter | subunit2pyunit. (Robert Collins)
516
* Stop sending apport crash files to ``.cache`` in the directory from
517
which ``bzr selftest`` was run. (Martin Pool, #422350)
519
* Tests no longer fail if "close() called during concurrent
520
operation on the same file object" occurs when closing the log file
521
(which can happen if a thread tries to write to the log file at the
522
wrong moment). An warning will be written to ``stderr`` when this
523
happens, and another warning will be written if the log file could not
524
be closed after retrying 100 times. (Andrew Bennetts, #531746)
529
:2.1.2: NOT RELEASED YET
534
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
535
(Aaron Bentley, #559436)
537
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
539
(Andrew Bennetts, #528041)
541
* Reset ``siginterrupt`` flag to False every time we handle a signal
542
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
543
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
544
errors after two window resizes.
550
* ``_remember_remote_is_before`` no longer raises AssertionError when
551
suboptimal network behaviour is noticed; instead it just mutters to the
552
log file (and warns the user if they have set the ``hpss`` debug flag).
553
This was causing unnecessary aborts for performance bugs that are minor
555
(Andrew Bennetts, #528041)
563
This is a small bugfix release. Upgrading is recommended for anyone
564
running 2.1.0 or earlier.
569
* Allow syscalls to automatically restart when ``TextUIFactory``'s
570
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
571
IO, which are often poorly handled by Python's libraries and parts of
572
bzrlib. (Andrew Bennetts, #496813)
574
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
575
(Martin Pool, #331095)
577
* Fix plugin packaging on Windows. (Ian Clatworthy, #524162)
579
* Fix stub sftp test server to call os.getcwdu().
580
(Vincent Ladeuil, #526221, #526353)
582
* Fixed CHM generation by moving the NEWS section template into
583
a separate file. (Ian Clatworthy, #524184)
585
* Merge correctly when this_tree is not a WorkingTree. (Aaron Bentley)
587
* Register SIGWINCH handler only when creating a ``TextUIFactory``; avoids
588
problems importing bzrlib from a non-main thread.
589
(Elliot Murphy, #521989)
591
* Repositories accessed via a smart server now reject being stacked on a
592
repository in an incompatible format, as is the case when accessing them
593
via other methods. This was causing fetches from those repositories via
594
a smart server (e.g. using ``bzr branch``) to receive invalid data.
595
(Andrew Bennetts, #562380)
597
* Standardize the error handling when creating a new ``StaticTuple``
598
(problems will raise TypeError). (Matt Nordhoff, #457979)
600
* Warn if pyrex is too old to compile the new ``SimpleSet`` and
601
``StaticTuple`` extensions, rather than having the build fail randomly.
602
(John Arbash Meinel, #449776)
607
* Added a link to the Desktop Guide. (Ian Clatworthy)
609
* Added What's New in Bazaar 2.1 document. (Ian Clatworthy)
611
* Drop Google Analytics from the core docs as they caused problems
612
in the CHM files. (Ian Clatworthy, #502010)
617
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
618
can set a signal handler and call ``signal.siginterrupt(signum,
619
False)`` for it, if the platform and Python version supports it.
620
(Andrew Bennetts, #496813)

This release marks our second long-term-stable series. The Bazaar team

has decided that we will continue to make bugfix-only 2.0.x and 2.1.x
631
releases, along with 2.2 development releases.
633
This is a fairly incremental update, focusing on polish and bugfixing.
634
There are no changes for supported disk formats. Key updates include
635
reduced memory consumption for many operations, a new per-file merge
636
hook, ignore patterns can now include '!' to exclude files, globbing
637
support for all commands on Windows, and support for addressing home
638
directories via ``bzr+ssh://host/~/`` syntax.
640
Users are encouraged to upgrade from the 2.0 stable series.
645
* Don't require testtools to use sftp.
646
(Vincent Ladeuil, #516183)
648
* Fix "AttributeError in Inter1and2Helper" during fetch.
649
(Martin Pool, #513432)
651
* ``bzr update`` performs the two merges in a more logical order and will stop
652
when it encounters conflicts.
653
(Gerard Krol, #113809)
655
* Give a better error message when doing ``bzr bind`` in an already bound
656
branch. (Neil Martinsen-Burrell, #513063)
658
* Ignore ``KeyError`` from ``remove_index`` during ``_abort_write_group``
659
in a pack repository, which can happen harmlessly if the abort occurs during
660
finishing the write group. Also use ``bzrlib.cleanup`` so that any
661
other errors that occur while aborting the individual packs won't be
662
hidden by secondary failures when removing the corresponding indices.
663
(Andrew Bennetts, #423015)
665
* Set the mtime of files exported to a directory by ``bzr export`` all to
666
the same value to avoid confusing ``make`` and other date-based build
667
systems. (Robert Collins, #515631)
672
* Fetching into experimental formats will now print a warning. (Jelmer
678
* ``Repository.deserialise_inventory`` has been renamed to
679
``Repository._deserialise_inventory`` to indicate it is private.
682
* ``Repository.get_inventory_xml`` has been renamed to
683
``Repository._get_inventory_xml`` to indicate it is private.
686
* ``Repository.serialise_inventory`` has been renamed to
687
``Repository._serialise_inventory`` to indicate it is private.
689
* Using the ``bzrlib.chk_map`` module from within multiple threads at the
690
same time was broken due to race conditions with a module level page
691
cache. This shows up as a KeyError in the ``bzrlib.lru_cache`` code with
692
``bzrlib.chk_map`` in the backtrace, and can be triggered without using
693
the same high level objects such as ``bzrlib.repository.Repository``
694
from different threads. chk_map now uses a thread local cache which may
695
increase memory pressure on processes using threads.
696
(Robert Collins, John Arbash Meinel, #514090)
698
* The new ``merge_file_content`` should now be ok with tests to avoid
700
(Vincent Ladeuil, #515597)
705
* Use ``bzrlib.cleanup`` rather than less robust ``try``/``finally``
706
blocks in several places in ``bzrlib.merge``. This avoids masking prior
707
errors when errors like ``ImmortalPendingDeletion`` occur during cleanup
709
(Andrew Bennetts, #517275)
714
* The ``remove_index`` method of
715
``bzrlib.repofmt.pack_repo.AggregateIndex`` no longer takes a ``pack``
716
argument. This argument was always ignored.
717
(Andrew Bennetts, #423015)
722
:Codename: after the bubbles
723
:2.1.0rc2: 2010-01-29
725
This is a quick-turn-around to update a small issue with our new per-file
726
merge hook. We expect no major changes from this to the final 2.1.0.
731
* The new ``merge_file_content`` hook point has been altered to provide a
732
better API where state for extensions can be stored rather than the
733
too-simple function based approach. This fixes a performance regression
734
where branch configuration would be parsed per-file during merge. As
735
part of this the included news_merger has been refactored into a base
736
helper class ``bzrlib.merge.ConfigurableFileMerger``.
737
(Robert Collins, John Arbash Meinel, #513822)
743
:Codename: the 'new' stable
744
:2.1.0rc1: 2009-01-21
746
This is the first stable release candidate for Bazaar's 2.1 series. From
747
this point onwards, the 2.1 series will be considered stable (as the 2.0
748
series) and only bugfixes are expected to be incorporated. The dozen or so
749
bugfixes in the 2.0.4 release are also included in this release (along
750
with more than 15 more bugfixes). Some of the interesting features are
751
support for per-file merge hooks, ``bzr unshelve --preview``, support
752
for using ! in ignore files to exclude files from being ignored, a small
753
memory leak was squashed, and many ``ObjectNotLocked`` errors were fixed.
754
This looks to be a very good start for a new stable series.
760
* Add bug information to log output when available.
761
(Neil Martinsen-Burrell, Guillermo Gonzalez, #251729)
763
* Added ``merge_file_content`` hook point to ``Merger``, allowing plugins
764
to register custom merge logic, e.g. to provide smarter merging for
767
* Bazaar now includes the ``news_merge`` plugin. It is disabled by
768
default, to enable it add a ``news_merge_files`` option to your
769
configuration. Consult ``bzr help news_merge`` for more information.
772
* ``bzr branch`` now takes a ``--bind`` option. This lets you
773
branch and bind all in one command. (Ian Clatworthy)
775
* ``bzr switch`` now takes a ``--revision`` option, to allow switching to
776
a specific revision of a branch. (Daniel Watkins, #183559)
778
* ``bzr unshelve --preview`` can now be used to show how a patch on the
779
shelf would be applied to the working tree.
780
(Guilherme Salgado, #308122)
782
* ``bzr update`` now takes a ``--revision`` argument. This lets you
783
change the revision of the working tree to any revision in the
784
ancestry of the current or master branch. (Matthieu Moy, Mark Hammond,
787
* ``-Dbytes`` can now be used to display the total number of bytes
788
transferred for the current command. This information is always logged
789
to ``.bzr.log`` for later inspection. (John Arbash Meinel)
791
* New ignore patterns. Patterns prefixed with '!' are exceptions to
792
ignore patterns and take precedence over regular ignores. Such
793
exceptions are used to specify files that should be versioned which
794
would otherwise be ignored. Patterns prefixed with '!!' act as regular
795
ignore patterns, but have highest precedence, even over the '!'
796
exception patterns. (John Whitley, #428031)
798
* The ``supress_warnings`` configuration option has been introduced to disable
799
various warnings (it currently only supports the ``format_deprecation``
800
warning). The new option can be set in any of the following locations:
801
``bazaar.conf``, ``locations.conf`` and/or ``branch.conf``.
802
(Ted Gould, Matthew Fuller, Vincent Ladeuil)
807
* Always show a message if an OS error occurs while trying to run a
808
user-specified commit message editor.
809
(Martin Pool, #504842)
811
* ``bzr diff`` will now use the epoch when it is unable to determine
812
the timestamp of a file, if the revision it was introduced in is a
813
ghost. (Jelmer Vernooij, #295611)
815
* ``bzr switch -b`` can now create branches that are located using directory
816
services such as ``lp:``, even when the branch name doesn't contain a
817
'/'. (Neil Martinsen-Burrell, #495263)
819
* ``bzr unshelve`` has improved messages about what it is doing.
820
(Neil Martinsen-Burrell, #496917)
822
* Concurrent autopacking is more resilient to already-renamed pack files.
823
If we find that a file we are about to obsolete is already obsoleted, we
824
do not try to rename it, and we leave the file in ``obsolete_packs``.
825
The code is also fault tolerant if a file goes missing, assuming that
826
another process already removed the file.
827
(John Arbash Meinel, Gareth White, #507557)
829
* Fix "Too many concurrent requests" in reconcile when network connection
830
fails. (Andrew Bennetts, #503878)
832
* Fixed a side effect mutation of ``RemoteBzrDirFormat._network_name``
833
that caused some tests to fail when run in a non-default order.
834
Probably no user impact. (Martin Pool, #504102)
836
* Fixed ``ObjectNotLocked`` error in ``bzr cat -rbranch:../foo FILE``.
837
(Andrew Bennetts, #506274)
839
* FTP transports support Unicode paths by encoding/decoding them as utf8.
840
(Vincent Ladeuil, #472161)
842
* Listen to the SIGWINCH signal to update the terminal width.
843
(Vincent Ladeuil, #316357)
845
* Progress bars are now hidden when ``--quiet`` is given.
846
(Martin Pool, #320035)
848
* ``SilentUIFactory`` now supports ``make_output_stream`` and discards
849
whatever is written to it. This un-breaks some plugin tests that
850
depended on this behaviour.
851
(Martin Pool, #499757)
853
* When operations update the working tree, all affected files should end
854
up with the same mtime. (eg. when versioning a generated file, if you
855
update the source and the generated file together, the generated file
856
should appear up-to-date.)
857
(John Arbash Meinel, Martin <gzlist>, #488724)
862
* Added ``add_cleanup`` and ``cleanup_now`` to ``bzrlib.command.Command``.
863
All the builtin commands now use ``add_cleanup`` rather than
864
``try``/``finally`` blocks where applicable as it is simpler and more
865
robust. (Andrew Bennetts)
867
* All except a small number of storage formats are now hidden, making
868
the help for numerous commands far more digestible. (Ian Clatworthy)
870
* Attempts to open a shared repository as a branch (e.g. ``bzr branch
871
path/to/repo``) will now include "location is a repository" as a hint in
872
the error message. (Brian de Alwis, Andrew Bennetts, #440952)
874
* Push will now inform the user when they are trying to push to a foreign
875
VCS for which roundtripping is not supported, and will suggest them to
876
use dpush. (Jelmer Vernooij)
878
* The version of bzr being run is now written to the log file.
881
* Transport network activity indicator is shown more of the time when
882
Bazaar is doing network IO.
888
* Add documentation on creating merges with more than one parent.
889
(Neil Martinsen-Burrell, #481526)
891
* Better explain the --uncommitted option of merge.
892
(Neil Martinsen-Burrell, #505088)
894
* Improve discussion of pending merges in the documentation for
895
``revert``. (Neil Martinsen-Burrell, #505093)
897
* Improved help for ``bzr send``.
898
(Martin Pool, Bojan Nikolic)
900
* There is a System Administrator's Guide in ``doc/en/admin-guide``,
901
including discussions of installation, relevant plugins, security and
902
backup. (Neil Martinsen-Burrell)
904
* The ``conflicts`` help topic has been renamed to ``conflict-types``.
907
* The User Reference is now presented as a series of topics.
908
Many of the included topics have link and format tweaks applied.
914
* Added ``cachedproperty`` decorator to ``bzrlib.decorators``.
917
* Many test features were renamed from ``FooFeature`` to ``foo_feature``
918
to be consistent with instances being lower case and classes being
919
CamelCase. For the features that were more likely to be used, we added a
920
deprecation thunk, but not all. (John Arbash Meinel)
922
* Merger classes (such as ``Merge3Merger``) now expect a ``this_branch``
923
parameter in their constructors, and provide ``this_branch`` as an
924
attribute. (Andrew Bennetts)
926
* The Branch hooks pre_change_branch_tip no longer masks exceptions raised
927
by plugins - the original exceptions are now preserved. (Robert Collins)
929
* The Transport ``Server.tearDown`` method is now renamed to
930
``stop_server`` and ``setUp`` to ``start_server`` for consistency with
931
our normal naming pattern, and to avoid confusion with Python's
932
``TestCase.tearDown``. (Martin Pool)
934
* ``WorkingTree.update`` implementations must now accept a ``revision``
940
* Added ``BzrDir.open_branchV3`` smart server request, which can receive
941
a string of details (such as "location is a repository") as part of a
942
``nobranch`` response. (Andrew Bennetts, #440952)
944
* New helper osutils.UnicodeOrBytesToBytesWriter which encodes unicode
945
objects but passes str objects straight through. This is used for
946
selftest but may be useful for diff and other operations that generate
947
mixed output. (Robert Collins)
949
* New exception ``NoRoundtrippingSupport``, for use by foreign branch
950
plugins. (Jelmer Vernooij)
955
* ``bzrlib.tests.permute_for_extension`` is a helper that simplifies
956
running all tests in the current module, once against a pure python
957
implementation, and once against an extension (pyrex/C) implementation.
958
It can be used to dramatically simplify the implementation of
959
``load_tests``. (John Arbash Meinel)
961
* ``bzrlib.tests.TestCase`` now subclasses ``testtools.testcase.TestCase``.
962
This permits features in testtools such as getUniqueInteger and
963
getUniqueString to be used. Because of this, testtools version 0.9.2 or
964
newer is now a dependency to run bzr selftest. Running with versions of
965
testtools less than 0.9.2 will cause bzr to error while loading the test
966
suite. (Robert Collins)
968
* Shell-like tests now support the command "mv" for moving files. The
969
syntax for ``mv file1 file2``, ``mv dir1 dir2`` and ``mv file dir`` is
970
supported. (Neil Martinsen-Burrell)
972
* The test progress bar no longer distinguishes tests that 'errored' from
973
tests that 'failed' - they're all just failures.
979
:2.0.6: NOT RELEASED YET
984
* Additional merges after an unrelated branch has been merged with its
985
history no longer crash when deleted files are involved.
986
(Vincent Ladeuil, John Arbash Meinel, #375898)
988
* ``bzr revert`` now only takes write lock on working tree, instead of on
989
both working tree and branch.
990
(Danny van Heumen, #498409)
992
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
993
permissions as ``.bzr`` directory on a POSIX OS.
994
(Parth Malwankar, #262450)
996
* Repositories accessed via a smart server now reject being stacked on a
997
repository in an incompatible format, as is the case when accessing them
998
via other methods. This was causing fetches from those repositories via
999
a smart server (e.g. using ``bzr branch``) to receive invalid data.
1000
(Andrew Bennetts, #562380)
1007
This fifth release in our 2.0 series addresses several user-inconvenience
1008
bugs. None are critical, but upgrading is recommended for all users on
1009
earlier 2.0 releases.
1014
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1015
(Martin Pool, #331095)
1017
* Concurrent autopacking is more resilient to already-renamed pack files.
1018
If we find that a file we are about to obsolete is already obsoleted, we
1019
do not try to rename it, and we leave the file in ``obsolete_packs``.
1020
The code is also fault tolerant if a file goes missing, assuming that
1021
another process already removed the file.
1022
(John Arbash Meinel, Gareth White, #507557)
1024
* Cope with the lockdir ``held/info`` file being empty, which seems to
1025
happen fairly often if the process is suddenly interrupted while taking
1027
(Martin Pool, #185103)
1029
* Give the warning about potentially slow cross-format fetches much
1030
earlier on in the fetch operation. Don't show this message during
1031
upgrades, and show the correct format indication for remote
1033
(Martin Pool, #456077, #515356, #513157)
1035
* Handle renames correctly when there are files or directories that
1036
differ only in case. (Chris Jones, Martin Pool, #368931)
1038
* If ``bzr push --create-prefix`` triggers an unexpected ``NoSuchFile``
1039
error, report that error rather than failing with an unhelpful
1040
``UnboundLocalError``.
1041
(Andrew Bennetts, #423563)
1043
* Running ``bzr`` command without any arguments now shows bzr
1044
version number along with rest of the help text.
1045
(Parth Malwankar, #369501)
1047
* Use osutils.O_NOINHERIT for some files on win32 to avoid PermissionDenied
1049
(Inada Naoki, #524560)
1054
* Added ``location-alias`` help topic.
1055
(Andrew Bennetts, #337834)
1057
* Fixed CHM generation by moving the NEWS section template into
1058
a separate file. (Ian Clatworthy, #524184)
1064
:Codename: smooth sailing
1067
The fourth bugfix-only release in the 2.0 series contains more than a
1068
dozen bugfixes relative to 2.0.3. The primary focus is on handling
1069
interruptions and concurrent operations more cleanly, there is also a fair
1070
improvement to ``bzr export`` when exporting a remote branch.

bzr 2.0.4 (not released yet)

:2.0.4: smooth sailing
1354
105
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
1360
:Codename: after sprint recovery
1361
:2.1.0b3: 2009-11-16
1363
This release was pushed up from its normal release cycle due to a
1364
regression in python 2.4 compatibility in 2.1.0b2. Since this regression
1365
was caught before 2.1.0b2 was officially announced, the full changelog
1366
includes both 2.1.0b3 and 2.1.0b2 changes.
1368
Highlights of 2.1.0b3 are: new globbing code for all commands on Windows,
1369
the test suite now conforms to python's trunk enhanced semantics (skip,
1370
etc.), and ``bzr info -v`` will now report the correct branch and repo
1371
formats for Remote objects.
1377
* Users can define a shelve editor to provide shelf functionality at a
1378
granularity finer than per-patch-hunk. (Aaron Bentley)
1383
* Fix for shell completion and short options. (Benoît PIERRE)
1385
* Fix ``bzr --profile-imports`` with Python 2.6. (Martin Pool)
1387
* Hooks daughter classes should always call the base constructor.
1388
(Alexander Belchenko, Vincent Ladeuil, #389648)
1390
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
1392
* On Windows, do glob expansion at the command-line level (as is usually
1393
done in bash, etc.) This means that *all* commands get glob expansion
1394
(bzr status, bzr add, bzr mv, etc). It uses a custom command line
1395
parser, which allows us to know if a given section was quoted. It means
1396
you can now do ``bzr ignore "*.py"``.
1397
(John Arbash Meinel, #425510, #426410, #194450)
1399
* Sanitize commit messages that come in from the '-m' flag. We translate
1400
'\r\n' => '\n' and a plain '\r' => '\n'. The storage layer doesn't
1401
allow those because XML store silently translate it anyway. (The parser
1402
auto-translates \r\n => \n in ways that are hard for us to catch.)
1404
* Show correct branch and repository format descriptions in
1405
``bzr info -v`` on a smart server location. (Andrew Bennetts, #196080)
1407
* The fix for bug #186920 accidentally broke compatibility with python
1408
2.4. (Vincent Ladeuil, #475585)
1410
* Using ``Repository.get_commit_builder().record_iter_changes()`` now
1411
correctly sets ``self.inv_sha1`` to a sha1 string and
1412
``self.new_inventory`` to an Inventory instance after calling
1413
``self.finish_inventory()``. (Previously it accidently set both values
1414
as a tuple on ``self.inv_sha1``. This was missed because
1415
``repo.add_revision`` ignores the supplied inventory sha1 and recomputes
1416
the sha1 from the repo directly. (John Arbash Meinel)
1418
* Shelve command refuse to run if there is no real terminal.
1419
(Alexander Belchenko)
1421
* Avoid unnecessarily flushing of trace file; it's now unbuffered at the
1422
Python level. (Martin Pool)
1427
* Include Japanese translations for documentation (Inada Naoki)
1429
* New API ``ui_factory.make_output_stream`` to be used for sending bulk
1430
(rather than user-interaction) data to stdout. This automatically
1431
coordinates with progress bars or other terminal activity, and can be
1433
(Martin Pool, 493944)
1438
* Some of the core groupcompress functionality now releases the GIL before
1439
operation. Similar to how zlib and bz2 operate without the GIL in the
1440
core compression and decompression routines. (John Arbash Meinel)
1445
* -Dhpssvfs will now trigger on ``RemoteBzrDir._ensure_real``, providing
1446
more debugging of VFS access triggers. (Robert Collins)
1448
* KnownFailure is now signalled to ``ExtendedTestResult`` using the same
1449
method that Python 2.7 uses - ``addExpectedFailure``. (Robert Collins)
1451
* ``--parallel=fork`` is now compatible with --subunit.
1452
(Robert Collins, Vincent Ladeuil, #419776)
1454
* Reporting of failures shows test ids not descriptions and thus shows
1455
parameterised tests correctly. (Robert Collins)
1457
* TestNotApplicable is now handled within the TestCase.run method rather
1458
than being looked for within ``ExtendedTestResult.addError``. This
1459
provides better handling with other ``TestResult`` objects, degrading to
1460
sucess rather than error. (Robert Collins)
1462
* The private method ``_testConcluded`` on ``ExtendedTestResult`` has been
1463
removed - it was empty and unused. (Robert Collins)
1465
* UnavailableFeature is now handled within the TestCase.run method rather
1466
than being looked for within addError. If the Result object does not
1467
have an addNotSupported method, addSkip is attempted instead, and
1468
failing that addSuccess. (Robert Collins)
1470
* When a TestResult does not have an addSkip method, skipped tests are now
1471
reported as successful tests, rather than as errors. This change is
1472
to make it possible to get a clean test run with a less capable
1473
TestResult. (Robert Collins)
1480
:Codename: a load off my mind
1481
:2.1.0b2: 2009-11-02
1483
This is our second feature-filled release since 2.0, pushing us down the
1484
path to a 2.1.0. Once again, all bugfixes in 2.0.2 are present in 2.1.0b2.
1486
Key highlights in this release are: improved handling of
1487
failures-during-cleanup for commit, fixing a long-standing bug with
1488
``bzr+http`` and shared repositories, all ``lp:`` urls to be resolved
1489
behind proxies, and a new StaticTuple datatype, allowing us to reduce
1490
memory consumption (50%) and garbage collector overhead (40% faster) for
1493
* A new ``--concurrency`` option has been added as well as an associated
1494
BZR_CONCURRENCY environment variable to specify the number of
1495
processes that can be run concurrently when running ``bzr selftest``. The
1496
command-line option overrides the environment variable if both are
1497
specified. If none is specified. the number of processes is obtained
1498
from the OS as before. (Matt Nordhoff, Vincent Ladeuil)
1503
* ``bzr+http`` servers no longer give spurious jail break errors when
1504
serving branches inside a shared repository. (Andrew Bennetts, #348308)
1506
* Errors during commit are handled more robustly so that knock-on errors
1507
are less likely to occur, and will not obscure the original error if
1508
they do occur. This fixes some causes of ``TooManyConcurrentRequests``
1509
and similar errors. (Andrew Bennetts, #429747, #243391)
1511
* Launchpad urls can now be resolved from behind proxies.
1512
(Gordon Tyler, Vincent Ladeuil, #186920)
1514
* Reduce the strictness for StaticTuple, instead add a debug flag
1515
``-Dstatic_tuple`` which will change apis to be strict and raise errors.
1516
This way, most users won't see failures, but developers can improve
1517
internals. (John Arbash Meinel, #471193)
1519
* TreeTransform.adjust_path updates the limbo paths of descendants of adjusted
1520
files. (Aaron Bentley)
1522
* Unicode paths are now handled correctly and consistently by the smart
1523
server. (Andrew Bennetts, Michael Hudson, #458762)
1528
* When reading index files, we now use a ``StaticTuple`` rather than a
1529
plain ``tuple`` object. This generally gives a 20% decrease in peak
1530
memory, and can give a performance boost up to 40% on large projects.
1531
(John Arbash Meinel)
1533
* Peak memory under certain operations has been reduced significantly.
1534
(eg, 'bzr branch launchpad standalone' is cut in half)
1535
(John Arbash Meinel)
1540
* Filtered views user documentation upgraded to refer to format 2a
1541
instead of pre-2.0 formats. (Ian Clatworthy)
1546
* Remove deprecated ``CLIUIFactory``. (Martin Pool)
1548
* ``UIFactory`` now has new ``show_error``, ``show_message`` and
1549
``show_warning`` methods, which can be hooked by non-text UIs.
1555
* Added ``bzrlib._simple_set_pyx``. This is a hybrid between a Set and a
1556
Dict (it only holds keys, but you can lookup the object located at a
1557
given key). It has significantly reduced memory consumption versus the
1558
builtin objects (1/2 the size of Set, 1/3rd the size of Dict). This is
1559
used as the interning structure for StaticTuple objects.
1560
(John Arbash Meinel)
1562
* ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
1563
the btree index parser and the chk map parser. This class functions
1564
similarly to ``tuple`` objects. However, it can only point to a limited
1565
collection of types. (Currently StaticTuple, str, unicode, None, bool,
1566
int, long, float, but not subclasses). This allows us to remove it from
1567
the garbage collector (it cannot be in a cycle), it also allows us to
1568
intern the objects. In testing, this can reduce peak memory by 20-40%,
1569
and significantly improve performance by removing objects from being
1570
inspected by the garbage collector. (John Arbash Meinel)
1572
* ``GroupCompressBlock._ensure_content()`` will now release the
1573
``zlib.decompressobj()`` when the first request is for all of the
1574
content. (Previously it would only be released if you made a request for
1575
part of the content, and then all of it later.) This turns out to be a
1576
significant memory savings, as a ``zstream`` carries around approx 260kB
1577
of internal state and buffers. (For branching bzr.dev this drops peak
1578
memory from 382MB => 345MB.) (John Arbash Meinel)
1580
* When streaming content between ``2a`` format repositories, we now clear
1581
caches from earlier versioned files. (So 'revisions' is cleared when we
1582
start reading 'inventories', etc.) This can have a significant impact on
1583
peak memory for initial copies (~200MB). (John Arbash Meinel)
1630
152
instead of pre-2.0 formats. (Ian Clatworthy)
1636
:Codename: While the cat is away
1637
:2.1.0b1: 2009-10-14
1639
This is the first development release in the new split "stable" and
1640
"development" series. As such, the release is a snapshot of bzr.dev
1641
without creating a release candidate first. This release includes a
1642
fair amount of internal changes, with deprecated code being removed,
1643
and several new feature developments. People looking for a stable code
1644
base with only bugfixes should focus on the 2.0.1 release. All bugfixes
1645
present in 2.0.1 are present in 2.1.0b1.
1647
Highlights include support for ``bzr+ssh://host/~/homedir`` style urls,
1648
finer control over the plugin search path via extended BZR_PLUGIN_PATH
1649
syntax, visible warnings when extension modules fail to load, and improved
1650
error handling during unlocking.
1656
* Bazaar can now send mail through Apple OS X Mail.app.
1659
* ``bzr+ssh`` and ``bzr`` paths can now be relative to home directories
1660
specified in the URL. Paths starting with a path segment of ``~`` are
1661
relative to the home directory of the user running the server, and paths
1662
starting with ``~user`` are relative to the home directory of the named
1663
user. For example, for a user "bob" with a home directory of
1664
``/home/bob``, these URLs are all equivalent:
1666
* ``bzr+ssh://bob@host/~/repo``
1667
* ``bzr+ssh://bob@host/~bob/repo``
1668
* ``bzr+ssh://bob@host/home/bob/repo``
1670
If ``bzr serve`` was invoked with a ``--directory`` argument, then no
1671
home directories outside that directory will be accessible via this
1674
This is a feature of ``bzr serve``, so pre-2.1 clients will
1675
automatically benefit from this feature when ``bzr`` on the server is
1676
upgraded. (Andrew Bennetts, #109143)
1678
* Extensions can now be compiled if either Cython or Pyrex is available.
1679
Currently Pyrex is preferred, but that may change in the future.
1682
* Give more control on BZR_PLUGIN_PATH by providing a way to refer to or
1683
disable the user, site and core plugin directories.
1684
(Vincent Ladeuil, #412930, #316192, #145612)
1689
* Bazaar's native protocol code now correctly handles EINTR, which most
1690
noticeably occurs if you break in to the debugger while connected to a
1691
bzr+ssh server. You can now can continue from the debugger (by typing
1692
'c') and the process continues. However, note that pressing C-\ in the
1693
shell may still kill the SSH process, which is bug 162509, so you must
1694
sent a signal to the bzr process specifically, for example by typing
1695
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
1697
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
1698
filename will issue a warning and skip over those files.
1699
(Robert Collins, #3918)
1701
* ``bzr dpush`` now aborts if uncommitted changes (including pending merges)
1702
are present in the working tree. The configuration option ``dpush_strict``
1703
can be used to set the default for this behavior.
1704
(Vincent Ladeuil, #438158)
1706
* ``bzr merge`` and ``bzr remove-tree`` now requires --force if pending
1707
merges are present in the working tree.
1708
(Vincent Ladeuil, #426344)
1710
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
1711
traceback. (Martin Pool, #109115)
1713
* Don't give a warning on Windows when failing to import ``_readdir_pyx``
1714
as it is never built. (John Arbash Meinel, #430645)
1716
* Don't restrict the command name used to run the test suite.
1717
(Vincent Ladeuil, #419950)
1719
* ftp transports were built differently when the kerberos python module was
1720
present leading to obscure failures related to ASCII/BINARY modes.
1721
(Vincent Ladeuil, #443041)
1723
* Network streams now decode adjacent records of the same type into a
1724
single stream, reducing layering churn. (Robert Collins)
1726
* PreviewTree behaves correctly when get_file_mtime is invoked on an unmodified
1727
file. (Aaron Bentley, #251532)
1729
* Registry objects should not use iteritems() when asked to use items().
1730
(Vincent Ladeuil, #430510)
1732
* Weave based repositories couldn't be cloned when committers were using
1733
domains or user ids embedding '.sig'. Now they can.
1734
(Matthew Fuller, Vincent Ladeuil, #430868)
1739
* Revision specifiers can now be given in a more DWIM form, without
1740
needing explicit prefixes for specifiers like tags or revision id's.
1741
See ``bzr help revisionspec`` for full details. (Matthew Fuller)
1743
* Bazaar gives a warning before exiting, and writes into ``.bzr.log``, if
1744
compiled extensions can't be loaded. This typically indicates a
1745
packaging or installation problem. In this case Bazaar will keep
1746
running using pure-Python versions, but this may be substantially
1747
slower. The warning can be disabled by setting
1748
``ignore_missing_extensions = True`` in ``bazaar.conf``.
1749

1750
(Martin Pool, #406113, #430529)
1752
* Secondary errors that occur during Branch.unlock and Repository.unlock
1753
no longer obscure the original error. These methods now use a new
1754
decorator, ``only_raises``. This fixes many causes of
1755
``TooManyConcurrentRequests`` and similar errors.
1756
(Andrew Bennetts, #429747)
1761
* Describe the new shell-like test feature. (Vincent Ladeuil)
1763
* Help on hooks no longer says 'Not deprecated' for hooks that are
1764
currently supported. (Ian Clatworthy, #422415)
1769
* ``bzrlib.user_encoding`` has been removed; use
1770
``bzrlib.osutils.get_user_encoding`` instead. (Martin Pool)
1772
* ``bzrlib.tests`` now uses ``stopTestRun`` for its ``TestResult``
1773
subclasses - the same as python's unittest module. (Robert Collins)
1775
* ``diff._get_trees_to_diff`` has been renamed to
1776
``diff.get_trees_and_branches_to_diff``. It is now a public API, and it
1777
returns the old and new branches. (Gary van der Merwe)
1779
* ``bzrlib.trace.log_error``, ``error`` and ``info`` have been deprecated.
1782
* ``MutableTree.has_changes()`` does not require a tree parameter anymore. It
1783
now defaults to comparing to the basis tree. It now checks for pending
1784
merges too. ``Merger.check_basis`` has been deprecated and replaced by the
1785
corresponding has_changes() calls. ``Merge.compare_basis``,
1786
``Merger.file_revisions`` and ``Merger.ensure_revision_trees`` have also
1788
(Vincent Ladeuil, #440631)
1790
* ``ProgressTask.note`` is deprecated.
1796
* Added ``-Drelock`` debug flag. It will ``note`` a message every time a
1797
repository or branch object is unlocked then relocked the same way.
1800
* ``BTreeLeafParser.extract_key`` has been tweaked slightly to reduce
1801
mallocs while parsing the index (approx 3=>1 mallocs per key read).
1802
This results in a 10% speedup while reading an index.
1803
(John Arbash Meinel)
1805
* The ``bzrlib.lsprof`` module has a new class ``BzrProfiler`` which makes
1806
profiling in some situations like callbacks and generators easier.
1812
* Passing ``--lsprof-tests -v`` to bzr selftest will cause lsprof output to
1813
be output for every test. Note that this is very verbose! (Robert Collins)
1815
* Setting ``BZR_TEST_PDB=1`` when running selftest will cause a pdb
1816
post_mortem to be triggered when a test failure occurs. (Robert Collins)
1818
* Shell-like tests can now be written. Code in ``bzrlib/tests/script.py`` ,
1819
documentation in ``developers/testing.txt`` for details.
1822
* Some tests could end up with the same id, that was dormant for
1824
(Vincent Ladeuil, #442980)
1826
* Stop showing the number of tests due to missing features in the test
1827
progress bar. (Martin Pool)
1829
* Test parameterisation now does a shallow copy, not a deep copy of the test
1830
to be parameterised. This is not expected to break external use of test
1831
parameterisation, and is substantially faster. (Robert Collins)
1833
* Tests that try to open a bzr dir on an arbitrary transport will now
1834
fail unless they have explicitly permitted the transport via
1835
``self.permit_url``. The standard test factories such as ``self.get_url``
1836
will permit the urls they provide automatically, so only exceptional
1837
tests should need to do this. (Robert Collins)
1839
* The break-in test no longer cares about clean shutdown of the child,
1840
instead it is happy if the debugger starts up. (Robert Collins)
1842
* The full test suite is expected to pass when the C extensions are not
1843
present. (Vincent Ladeuil, #430749)
