: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()``.
12
:2.2.0b1: Not released yet
246
14
Compatibility Breaks
247
15
********************
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
17
* Deleted very old hidden commands ``versionedfile-list``,
253
18
``weave-plan-merge``, ``weave-merge-text``.
266
31
``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
37
* If the Apport crash-reporting tool is available, bzr crashes are now
284
38
stored into the ``/var/crash`` apport spool directory, and the user is
285
39
invited to report them to the developers from there, either
286
40
automatically or by running ``apport-bug``. No information is sent
287
41
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
43
* Tree-shape conflicts can be resolved by providing ``--take-this`` and
309
44
``--take-other`` to the ``bzr resolve`` command. Just marking the conflict
310
45
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
51
* Added docstring for ``Tree.iter_changes``
320
52
(John Arbash Meinel, #304182)
322
* Allow additional arguments to
323
``RemoteRepository.add_inventory_by_delta()``. (Jelmer Vernooij, #532631)
325
54
* Allow exporting a single file using ``bzr export``.
326
55
(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
57
* Avoid infinite recursion when probing for apport.
334
58
(Vincent Ladeuil, #516934)
336
60
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
337
61
(Martin Pool, #331095)
339
* Avoid truncating svn URLs.
340
(Martin Pool, Martin von Gagern, #545185)
342
63
* ``bzr add`` will not add conflict related files unless explicitly required.
343
64
(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
66
* ``bzr remove-tree`` can now remove multiple working trees.
360
67
(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
69
* Network transfer amounts and rates are now displayed in SI units according
405
70
to the Ubuntu Units Policy <https://wiki.ubuntu.com/UnitsPolicy>.
406
71
(Gordon Tyler, #514399)
409
74
prevents ``bzr status --short`` from crashing when those files are
410
75
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
80
* New ``bzrlib.initialize`` is recommended for programs using bzrlib to
448
81
run when starting up; it sets up several things that previously needed
449
82
to be done separately.
450
83
(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
85
* 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
91
* New `bzrlib.tests.test_import_tariff` can make assertions about what
509
92
Python modules are loaded, to guard against startup time or library
510
93
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
96
* Stop sending apport crash files to ``.cache`` in the directory from
517
97
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.

: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.

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

(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
