:Codename: Monkey Magic
12
:2.2b4: NOT RELEASED YET
17
* bzrlib library users now need to call ``__enter__`` and ``__exit__`` on
18
the result of ``bzrlib.initialize``. This change was made when fixing
19
the bad habit recent bzr versions have had of leaving progress bars
20
behind on the screen. That required calling another function before
21
exiting the program, and it made sense to provide a full context
22
manager at the same time. (Robert Collins)
24
* The ``bzr`` front end now requires a ``bzrlib.ui.ui_factory`` which is a
25
context manager in the Python 2.5 and above sense. The bzrlib base class
26
is such a manager, but third party UI factories which do not derive from
27
``bzrlib.ui.UIFactory`` will be incompatible with the command line front
30
* URLs like ``foo:bar/baz`` are now always parsed as a URL with scheme "foo"
31
and path "bar/baz", even if bzr does not recognize "foo" as a known URL
32
scheme. Previously these URLs would be treated as local paths.
39
* Support ``--directory`` option for a number of additional commands:
40
conflicts, merge-directive, missing, resolve, shelve, switch,
41
unshelve, whoami. (Martin von Gagern, #527878)
46
* ``bzr branch`` to a new repository with a default stacking policy no
47
longer transfers the full history unnecessarily.
48
(Andrew Bennetts, #597942)
50
* ``bzr init`` does not recursively scan directory contents anymore
51
leading to faster init for directories with existing content.
52
(Martin [gz], Parth Malwankar, #501307)
54
* ``bzr log --exclude-common-ancestry`` is now taken into account for
55
linear ancetries. (Vincent Ladeuil, #575631)
57
* ``bzr log -r branch:REMOTE`` can now properly log the remote branch,
58
rather than trying to fetch the data locally and failing because of a
59
readonly error. (Martin von Gagern, #149270)
61
* ``bzr pull`` now works when a lp: URL is explicitly defined as the parent
62
or pull location in locations.conf or branch.conf.
63
(Gordon Tyler, #534787)
65
* ``bzr reconfigure --unstacked`` now works with branches accessed via a
66
smart server. (Andrew Bennetts, #551525)
68
* ``BzrDir.find_branches`` should ignore branches with missing repositories.
69
(Marius Kruger, Robert Collins)
71
* ``BzrDir.find_bzrdirs`` should ignore dirs that raises PermissionDenied.
72
(Marius Kruger, Robert Collins)
74
* Ensure that wrong path specifications in ``BZR_PLUGINS_AT`` display
75
proper error messages. (Vincent Ladeuil, #591215)
77
* Explicitly removing ``--profile-imports`` option from parsed command-line
78
arguments on Windows, because bzr script does the same.
79
(Alexander Belchenko, #588277)
81
* Fetching was slightly confused about the best code to use and was
82
using a new code path for all branches, resulting in more lookups than
83
necessary on old branches. (Robert Collins, #593515)
85
* Final fix for 'no help for command' issue. We now show a clean message
86
when a command has no help, document how to set help more clearly, and
87
test that all commands available to the test suite have help.
88
(Robert Collins, #177500)
90
* Progress output is cleaned up when exiting. (Aaron Bentley)
92
* Raise ValueError instead of a string exception.
93
(John Arbash Meinel, #586926)
95
* Relative imports in plugins are now handled correctly when using
96
BZR_PLUGINS_AT. (Vincent Ladeuil, #588959)
98
* ``ScriptRunner`` now strips off leading indentation from test scripts,
99
which previously caused "SyntaxError: No command for line".
102
* Show unicode filenames in diff headers using terminal encoding.
103
(Alexander Belchenko, Bug #382699)
104
NOTE for Windows users: If user need to save diff to file then user need to
105
change encoding of the terminal to ANSI encoding with command ``chcp XXX``
106
(e.g. ``chcp 1251`` for Russian Windows).
108
* URL displayed for use with ``break-lock`` when smart server sees lock
109
contention are now valid. Default timeout for lock contention retry is
110
now 30 seconds instead of 300 seconds.
111
(Parth Malwankar, #250451)
113
* ``walkdirs`` now raises a useful message when the filenames are not using
114
the filesystem encoding. (Eric Moritz, #488519)
116
* Enable debugging of bzr on windows with pdb and other tools. This was
117
broken because we call GetCommandLineW on windows. The fix adjusts the
118
command line we get to be the same length as sys.argv.
119
(Jason Spashett, Alexander Belchenko, #587868)
124
* Bazaar now reads data from SSH connections more efficiently on platforms
125
that provide the ``socketpair`` function, and when using paramiko.
126
(Andrew Bennetts, #590637)
128
* ``Branch.copy_content_into`` is now a convenience method dispatching to
129
a ``InterBranch`` multi-method. This permits ``bzr-loom`` and other
130
plugins to intercept this even when a ``RemoteBranch`` proxy is in use.
131
(Robert Collins, #201613)
133
* ``Branch`` formats can now be loaded lazily by registering a
134
``MetaDirBranchFormatFactory`` rather than an actual format. This will
135
cause the named format class to be loaded only when an enumeration of
136
formats is needed or when the format string for the object is
137
encountered. (Robert Collins, Jelmer Vernooij)
139
* The encoding that bzr uses to output things other than file content can
140
now be overridden via the output_encoding configuration option.
141
(Martin Pool, #340394)
143
* Use lazy imports in ``bzrlib/merge.py`` so that plugins like ``news_merge``
144
do not cause modules to be loaded unnecessarily just because the plugin
145
registers a merge hook. This improves ``bzr rocks`` time by about 25%
146
in a default installation (with just the core plugins).
152
* Added ``regression`` tag to our tags list. (Robert Collins)
154
* Improved our release checklist to have a bit less churn and leave things
155
ready-to-go for the next action (including other people doing
156
development). (Robert Collins)
158
* Remove obsolete discussion of PQM in documentation about how to
159
contribute to Bazaar. (Martin Pool, #588444)
164
* ``bzrlib.branch.InterBranch._get_branch_formats_to_test`` now returns
165
an iterable of format pairs, rather than just a single pair, permitting
166
InterBranch objects that work with multiple permutations to be
167
comprehensively tested. (Robert Collins)
169
* ``bzrlib.lsprof.profile`` will no longer silently generate bad threaded
170
profiles when concurrent profile requests are made. Instead the profile
171
requests will be serialised. Reentrant requests will now deadlock.
174
* ``bzrlib.knit.KnitSequenceMatcher``, which has been deprecated since
175
2007, has been deleted. Use ``PatienceSequenceMatcher`` from
176
``bzrlib.patiencediff`` instead. (Andrew Bennetts)
178
* ``bzrlib.tests.blackbox.ExternalBase`` is deprecated. It provided only
179
one method ``check_output``, and we now recommend checking command
180
output using ``run_script``. (Martin Pool)
182
* ``bzrlib.transport.ssh.SSHVendor.connect_ssh`` now returns an object
183
that implements the interface of ``bzrlib.transport.ssh.SSHConnection``.
184
Third-party implementations of ``SSHVendor`` may need to be updated
185
accordingly. Similarly, any code using ``SSHConnection`` directly will
186
need to be updated. (Andrew Bennetts)
188
* The constructor of ``bzrilb.smart.medium.SmartSSHClientMedium`` has
189
changed to take an ``SSHParams`` instance (replacing many individual
190
values). (Andrew Bennetts)
195
* ``bzrlib.osutils.get_terminal_encoding`` will now only mutter its
196
selection when explicitly requested; this avoids many duplicate calls
197
being logged when helpers, wrappers and older code that manually calls
198
it are executed it is now logged deliberately by the ui setup code.
201
* Improved ``bzrlib.urlutils`` to handle lp:foo/bar URLs. (Gordon Tyler)
203
* ``bzrlib._c_static_tuple.StaticTuple`` now implements ``__sizeof__``, so
204
that ``sys.getsizeof`` and other memory analysis tools will report more
205
accurate results. (Andrew Bennetts)
207
* The symbol_versioning module can now cleanup after itself -
208
``suppress_deprecation_warnings`` now returns a cleanup function.
214
* Add ``bzrlib.tests.fixtures`` to hold code for setting up objects
215
to test. (Martin Pool)
217
* ``test_import_tariff`` now respects BZR_PLUGINS_AT and BZR_PLUGINS_DISABLE.
218
(Vincent Ladeuil, #595587)

:2.2b3: NOT RELEASED YET
225
This third beta in the 2.2 series brings with it all the goodness of 2.1.2
226
and 2.0.6 (though it preceeds 2.0.6 slightly). Of particular note for
227
users are compatibility fixes with bzr 1.5 and below servers, a hopeful
228
end to the EINTR errors caused by SIGWINCH interactions, a shiny new
229
bash completion script and bzr will no longer guess at identity details -
230
it was too unreliable in reality. Use ``bzr whoami`` on every new install.
231
For developers we have some API changes which may impact plugins as well
232
as a bunch of our regular improvements to internal clarity and test
13
235
Compatibility Breaks
14
236
********************
238
* An API break has been made to the lock_write method of ``Branch`` and
239
``Repository`` objects; they now return ``branch.BranchWriteLockResult``
240
and ``repository.RepositoryWriteLockResult`` objects. This makes
241
changing the API in future easier and permits some cleaner calling code.
242
The lock_read method has also changed from having no defined return
243
value to returning ``LogicalLockResult`` objects.
246
* ``bzr`` does not try to guess the username as ``username@hostname``
247
and requires it to be explictly set. This can be set using ``bzr
248
whoami``. (Parth Malwankar, #549310)
250
* ``bzrlib.commands.Command`` will now raise ValueError during
251
construction if there is no __doc__ set. (Note, this will be reverted in
252
2.2b4) (Robert Collins)
254
* The source tree no longer contains a contrib/zsh/_bzr completion
255
script. The new file contrib/zsh/README suggests alternatives.
256
(Martin von Gagern, #560030)
261
* ``bzr commit`` accepts ``-p`` (for "patch") as a shorter name for
263
(Parth Malwankar, #571467)
19
265
* ``bzr ignore`` now supports a ``--default-rules`` option that displays
20
266
the default ignore rules used by bzr. The flag ``--old-default-rules``
21
267
is no longer supported by ``ignore``.
27
273
(Parth Malwankar, #304320)
275
* New command line option ``--authors`` to ``bzr log`` allows users to
276
select which of the apparent authors and committer should be
277
included in the log. Defaults depend on format. (Martin von Gagern, #513322)
279
* Support ``--directory`` option for a number of additional commands:
280
added, annotate, bind, cat, cat-revision, clean-tree, deleted,
281
export, ignore, ignored, lookup-revision, ls, modified, nick,
282
re-sign, unbind, unknowns.
283
(Martin von Gagern, #527878)
285
* The bash_completion plugin from the bzr-bash-completion project has
286
been merged into the tree. It provides a bash-completion command and
287
replaces the outdated ``contrib/bash/bzr`` script with a version
288
using the plugin. (Martin von Gagern, #560030)
290
* A new transport based on GIO (the gnome i/o library) provides access to
291
samba shares, webdav using gio+smb and gio+dav. It is also possible to
292
use gio for some already existing transport methods as gio+file,
299
* Alias information shown by ``bzr help`` is now accurate. This
300
was showing an internal object name for some plugin aliases.
301
(Parth Malwankar, #584650)
32
303
* ``.bazaar``, ``.bazaar/bazaar.conf`` and ``.bzr.log`` inherit user and
33
304
group ownership from the containing directory. This allow bzr to work
35
306
(Martin <gzlist@googlemail.com>, Parth Malwankar, #376388)
308
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
309
support of bzr-externals and scmproj plugins.
310
(Alexander Belchenko, bug #572098)
312
* ``bzr ignore`` will no longer add duplicate patterns to .bzrignore.
313
(Gordon Tyler, #572092)
37
315
* ``bzr log --exclude-common-ancestry -r X..Y`` displays the revisions that
38
316
are part of Y ancestry but not part of X ancestry (aka the graph
40
318
(Vincent Ladeuil, #320119)
320
* ``bzr lp-propose`` which was switched to use production Launchpad API
321
servers a few commits ago has been reverted to use edge: there is a
322
problem with using production which isn't trivially obvious, so we've
323
filed a bug to track it, and until thats fixed will be using edge.
324
(Robert Collins, #583667)
326
* ``bzr rm`` should not refuse to delete directories which contained a file
327
which has been moved elsewhere in the tree after the previous commit.
328
(Marius Kruger, Daniel Watkins, #129880)
42
330
* ``bzr selftest --parallel=fork`` wait for its children avoiding zombies.
43
331
(Vincent Ladeuil, #566670)
45
333
* ``bzr selftest`` should not use ui.note() since it's not unicode safe.
46
334
(Vincent Ladeuil, #563997)
336
* CommitBuilder refuses to create revisions whose trees have no root.
339
* Do not register a SIGWINCH signal handler, instead just poll for the
340
terminal width as needed. This avoids the "Interrupted System Call"
341
problems that occur on POSIX with all currently released versions of
343
(Andrew Bennetts, #583941)
48
345
* Don't mention --no-strict when we just issue the warning about unclean trees.
49
346
(Vincent Ladeuil, #401599)
348
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
350
(Andrew Bennetts, #528041)
352
* Improved progress bar for fetch (2a format only). Bazaar now shows an
353
estimate of the number of records to be fetched vs actually fetched.
354
(Parth Malwankar, #374740, #538868)
51
356
* Reduce peak memory by one copy of compressed text.
52
357
(John Arbash Meinel, #566940)
359
* ``RemoteBranch.lock_write`` raises ``ReadOnlyError`` if called during a
360
read lock, rather than causing an ``AttributeError``.
361
(Andrew Bennetts, Данило Шеган, #582781)
363
* Selftest was failing with testtools 0.9.3, which caused an
364
AssertionError raised from a cleanUp to be reported as a Failure, not an
365
Error, breaking on of our test hygiene tests.
366
(Robert Collins, Vincent Ladeuil).
368
* ``set_user_option`` with a dict on remote branches no longer fails with
369
an AttributeError. There is a new ``Branch.set_config_option_dict`` RPC
370
to support this efficiently.
371
(Andrew Bennetts, #430382)
54
373
* Show the filenames when a file rename fails so that the error will be
55
374
more comprehensible.
56
375
(Martin Pool, #491763)
377
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
378
(John Arbash Meinel, #582656)
380
* Unicode characters in aliases are now handled correctly and do not cause
381
UnicodeEncodeError exception. (Parth Malwankar, #529930)
383
* Unicode commit messages that are the same as a file name no longer cause
384
UnicodeEncodeError. ``ui.text.show_warning`` now handles unicode
386
(Parth Malwankar, #563646)
388
* Using bzr with `lp:` urls behind an http proxy should work.
389
(Robert Collins, #558343)
391
* When passing a file to ``UTF8DirReader`` make sure to close the current
392
directory file handle after the chdir fails. Otherwise when passing many
393
filenames into a command line ``bzr status`` we would leak descriptors.
394
(John Arbash Meinel, #583486)
443
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
444
expected to return an object which can be used to unlock them. This reduces
445
duplicate code when using cleanups. The previous 'tokens's returned by
446
``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
447
on the result of the lock_write. ``repository.RepositoryWriteLockResult``
448
and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
450
* ``Repository.refresh_data`` may now be called in a write group on
451
pack-based repositories. Older repositories will still raise an error
452
in this case. Subclasses of ``Repository`` can still override
453
``Repository._refresh_data``, but are now responsible for raising
454
``bzrlib.repository.IsInWriteGroupError`` if they do not support
455
``refresh_data`` during a write group.
456
(Andrew Bennetts, #574236)
461
* ``chk_map._bytes_to_text_key`` is now an optimized function to extract
462
the (file-id, revision-id) key from a CHKInventory entry. This can
463
potentially shave 5-10% time off during a large fetch. Related to bug
464
#562666. (John Arbash Meinel)
466
* ``log._get_info_for_log_files`` now takes an add_cleanup callable.
469
* ``_remember_remote_is_before`` no longer raises AssertionError when
470
suboptimal network behaviour is noticed; instead it just mutters to the
471
log file (and warns the user if they have set the ``hpss`` debug flag).
472
This was causing unnecessary aborts for performance bugs that are minor
474
(Andrew Bennetts, #528041)
98
476
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
99
477
files loaded from disk. To ensure docstrings needed for help are never
100
478
stripped, the prefix ``__doc__ =`` should now be used.
101
479
(Martin <gzlist@googlemail.com>)
481
* No longer require zlib headers to build extensions, and remove the need
482
for seperate copy of zlib library on windows.
483
(John Arbash Meinel, Martin <gzlist@googlemail.com>, #66923)
488
* Added ``bzrlib.tests.matchers`` as a place to put matchers, along with
489
our first in-tree matcher. See the module docstring for details.
106
492
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
107
493
(Gordon Tyler, #551332)
509
923
happens, and another warning will be written if the log file could not
510
924
be closed after retrying 100 times. (Andrew Bennetts, #531746)
929
:Codename: Do run run
930
:2.1.3: NOT RELEASED YET
941
* Raise ValueError instead of a string exception.
942
(John Arbash Meinel, #586926)
964
This release fixes two critical networking issues with older servers and
965
with interrupted system call errors when pushing or pulling. We recommend
966
upgrading to anyone running a 2.1.x version of bzr.
971
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
972
support of bzr-externals and scmproj plugins.
973
(Alexander Belchenko, bug #572098)
975
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
976
(Aaron Bentley, #559436)
978
* Do not register a SIGWINCH signal handler, instead just poll for the
979
terminal width as needed. This avoids the "Interrupted System Call"
980
problems that occur on POSIX with all currently released versions of
982
(Andrew Bennetts, #583941)
984
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
986
(Andrew Bennetts, #528041)
988
* Reset ``siginterrupt`` flag to False every time we handle a signal
989
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
990
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
991
errors compared to registering ``signal.signal`` directly.
994
* Reduce peak memory by one copy of compressed text.
995
(John Arbash Meinel, #566940)
997
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
998
(John Arbash Meinel, #582656)
1000
* When passing a file to ``UTF8DirReader`` make sure to close the current
1001
directory file handle after the chdir fails. Otherwise when passing many
1002
filenames into a command line ``bzr status`` we would leak descriptors.
1003
(John Arbash Meinel, #583486)
1008
* ``_remember_remote_is_before`` no longer raises AssertionError when
1009
suboptimal network behaviour is noticed; instead it just mutters to the
1010
log file (and warns the user if they have set the ``hpss`` debug flag).

This was causing unnecessary aborts for performance bugs that are minor
