*****************************
16
.. These may require users to change the way they use Bazaar.
21
.. New commands, options, etc that users may wish to try out.
23
* The ``log_format`` configuration can be used with ``-Olog_format=line`` to
24
change the format ``push`` and ``pull`` use to display the
25
revisions. I.e.: ``bzr pull -v -Olog_format=short`` will use the ``short``
26
format instead of the default ``long`` one. (Vincent Ladeuil, #861472)
31
.. Improvements to existing commands, especially improved performance
32
or memory usage, or better results.
34
* ``bzr version-info`` now takes a ``--revision`` argument.
35
(Jelmer Vernooij, #238705)
37
* ``bzr revno`` now takes a ``--revision`` argument.
38
(Jelmer Vernooij, #870649)
43
.. Fixes for situations where bzr would previously crash or give incorrect
44
or undesirable results.
46
* ``bzr mkdir --quiet`` now does not print a line for every created
47
directory. (Martin von Gagern, #869915)
52
.. Improved or updated documentation.
57
.. Changes that may require updates in plugins or other code that uses
63
.. Major internal changes, unlikely to be visible to users or plugin
64
developers, but interesting for bzr developers.
69
.. Fixes and changes that are only relevant to bzr's test framework and
70
suite. This can include new facilities for writing tests, fixes to
71
spurious test failures and changes to the way things should be tested.
77
This is the second beta of the 2.5 series, leading to a 2.5.0 release in
78
February 2012. Beta releases are suitable for everyday use but may cause some
79
incompatibilities with plugins.
81
This release includes more filtering options for ``bzr log``, idle
82
connections handling for ``bzr serve``, a ``development-colo`` experimental
83
format to flesh out the colocated branches UI, better support for foreign
84
formats, enhancements to the config framework and more.
86
This release includes all bug fixed in previous series known at the time of

External Compatibility Breaks
92
*****************************
99
* A new ``-O`` standard option (common to all commands) have been added. It
100
provides a value for a config option in the ``-Oname=value`` form that
101
takes precedence over all definitions found in config files. It can be
102
used multiple times to override different options.
103
(Vincent Ladeuil, #491196)
105
* ``bzr log`` now has an option called ``--omit-merges`` to omit
106
those commits that merged branches, i.e. those having more than one
108
In order to avoid confusion, the previous command line option
109
``--include-merges`` has been renamed to ``--include-merged``.
110
The old name of the command line option will still be accepted.
111
The name change also affects ``bzr missing``.
114
* ``bzr serve`` will now disconnect clients if they have not issued an RPC
115
request after 5minutes. On POSIX platforms, this will also happen for
116
``bzr serve --inet``. This can be overridden with the configuration
117
variable ``serve.client_timeout`` or in the command line parameter
118
``bzr serve --client-timeout=X``. Further, it is possible to request
119
``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will
120
finish the current request, and then close the connection.
121
(John Arbash Meinel, #824797, #795025)
123
* The new experimental format ``development-colo`` supports colocated
124
branches. This format will eventually be merged back into the ``2a``
125
format when it has stabilized and there is adequate UI support for
127
(Jelmer Vernooij, #831481)
132
* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
133
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)
135
* ``bzr info -v`` can now be run against branches that don't support
136
``last_revision_info``, in which case the branch information will simply
137
not be displayed. (Jelmer Vernooij)
142
* ``bzr shelve`` can now be used in emacs shells as the input handling is
143
turned into a line-based one when ``INSIDE_EMACS`` is set (which is the
144
case for all recent emacs versions). (Vincent Ladeuil, #856261)
146
* ``bzr tags`` can now be used against remote repositories that do
147
not provide access to the revision graph. (Jelmer Vernooij, #858942)
149
* ``bzr update PATH`` will stop if you seem to be asking it to update
150
anything less than a whole tree, because that's not supported by ``bzr``'s
151
concept that the whole tree has a single basis revision. Previously, it
152
would go ahead and update the whole tree, which was surprising.
153
(Martin Pool, #557886)
155
* Don't crash if ``bzrlib.initialize()`` has not been called while accessing
156
configs. (Vincent Ladeuil, #863401)
158
* Redirects between http and https no longer discard path information
159
in some cases. (Jelmer Vernooij, #853765)
161
* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer
162
reports all tags as changed. (Jelmer Vernooij, #845396)
164
* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is
165
specified that is unknown. (Jelmer Vernooij, #847435)
171
* ``Branch.get_revision_delta`` has been deprecated. Use
172
``Repository.get_revision_delta`` instead. (Jelmer Vernooij, #859712)
174
* Plugins that implement custom protocols for ``bzr serve`` should now
175
also take an argument ``timeout``. This is used by the the bzr protocol
176
to close a connection if a client has been idle for more than X seconds.
177
(Default 5minutes). (John Arbash Meinel)
179
* ``Repository.fileids_altered_by_revision_ids`` has been moved to
180
``VersionedFileRepository`` and is no longer part of the standard
181
``Repository`` interface. (Jelmer Vernooij)
183
* The argument ``include_merges`` to ``missing.find_unmerged`` has
184
been renamed to ``include_merged``. The old name is still supported
185
for now but will cause a deprecation warning. (Martin von Gagern)
187
* The new method ``ControlDirFormat.is_initializable()`` returns a boolean
188
indicating whether or not it is possible to use any of the
189
initialization methods of that format to create a new control dir.
195
* ``Branch`` objects can now use a config stack with the newly introduced
196
``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can
197
be used for the same branch but it's recommended to stick to one for a
203
* Test scripts can now use ``bzr shelve`` and provide their input as
204
complete lines. (Vincent Ladeuil, #856261)
206
* Really corrupt the pack file without depending on a special length or value.
207
(Vincent Ladeuil, #807032)
215
This is the first beta of the 2.5 series, leading up to a 2.5.0
216
release in February 2012.
218
This release includes better support for gpg signing, better support for
219
i18n (mostly command help and error messages), more options to filter ``bzr
220
log`` output, more support for colocated branches ("location,branch=XXX"
221
syntax), better feedback on updated tags for various commands, faster
222
branching into an empty repository, enhancements to the config framework and
225
Beta releases are suitable for everyday use but may cause some
226
incompatibilities with plugins. Some plugins may need small updates to work
229
External Compatibility Breaks
230
*****************************
237
* A ``from_unicode`` parameter can be specified when registering a config
238
option. This implements boolean, integer and list config options when the
239
provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``
240
are used for this parameter. (Vincent Ladeuil)
242
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
243
checks to see if the most recent published source package version for
244
that project is present in the branch tags. This should help developers
245
trust whether the packaging branch is up-to-date and can be used for new
246
changes. The level of verbosity is controlled by the config item
247
``launchpad.packaging_verbosity``. It can be set to one of
254
only display if the branch is out-of-date
257
also display single-line up-to-date and missing,
261
(default) display multi-line content for all states
264
(John Arbash Meinel, #609187, #812928)
266
* Add a config option gpg_signing_key for setting which GPG key should
267
be used to sign commits. Also default to using the gpg user identity
268
which matches user_email() as set by whoami.
269
(Jonathan Riddell, #68501)
271
* An ``invalid`` parameter can be specified when registering a config option
272
to decide what should be done when invalid values are
273
encountered. 'warning' and 'error' will respectively emit a warning and
274
ignore the value or errors out. (Vincent Ladeuil)
276
* bzr add now skips large files in recursive mode. The default "large"
277
size is 20MB, and is configurable via the add.maximum_file_size
278
option. A value of 0 disables skipping. Named items passed to add are
279
never skipped. (Shannon Weyrick, #54624)
281
* ``bzr help configuration/<option>`` display the help for ``option`` for
282
all registered configuration options. (Vincent Ladeuil, #747050)
284
* ``bzr log -m`` now matches message, author, committer and bugs instead
285
of just matching the message. ``--message`` keeps its original meaning,
286
while ``--match-message, --match-author, --match-committer`` and
287
``--match-bugs`` match each of those fields. (Jacek Sieka)
289
* ``config.Option`` can now declare ``default_from_env``, a list of
290
environment variables to get a default value from. (Vincent Ladeuil)
292
* ``config.NameMatcher`` can be used to implement config stores and stacks
293
that need to provide specific option values for arbitrary unique IDs (svn
294
repository UUIDs, etc). (Vincent Ladeuil, #843638)
296
* New builtin ``bzr branches`` command, which lists all colocated branches
297
in a directory. (Jelmer Vernooij, #826820)
299
* Relative local paths can now be specified in URL syntax by using the
300
"file:" prefix. (Jelmer Vernooij)
302
* Report commits signed with expired keys in ``verify-signatures``.
303
(Jonathan Riddell, #804254)
305
* Translations are now enabled for command help, errors and globally
306
for any message using ``gettext`` given on output. (Jonathan Riddell,
312
* ``bzr add`` will now warn about nested subtrees that are skipped.
313
(Jelmer Vernooij, #187342)
315
* ``bzr commit -m ''`` can now be used to force an empty commit message.
316
Entering an empty commit message in the message editor still triggers
317
an error. (Jelmer Vernooij)
319
* ``bzr pull`` will now mention how many tags it has updated.
320
(Jelmer Vernooij, #164450)
322
* ``bzr tag`` no longer errors if a tag already exists but refers to the
323
same revision, and will mention when a tag has been updated
324
rather than created. (Jelmer Vernooij, #381203)
326
* ``bzr uncommit`` will now remove tags that refer to removed revisions.
327
The ``--keep-tags`` option can be used to prevent this behaviour.
328
(Jelmer Vernooij, #605814)
330
* Do not run i18n initialisation twice. (Jonathan Riddell)
332
* Install translation .mo files. (Jonathan Riddell)
334
* Locations printed by ``bzr upgrade`` are now formatted before display.
337
* ``Repository.get_parent_map`` now estimates the size of the returned
338
content more accurately. This means that we get closer to the desired
339
64kB/request. For repositories converted from svn, this can be an
340
improvement of approx 5:1 in round trips to discover the whole history.
343
* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
344
if no bug tracker was specified on the command line.
345
(Jelmer Vernooij, #334860)
347
* Use ``gettext.NullTranslations`` in i18n to allow use of i18n even when
348
translations are not turned on. (Jonathan Riddell)
353
* ``bzr commit`` now correctly reports missing files as "removed", not
354
"modified". (Jelmer Vernooij, #553955)
356
* ``bzr reconfigure`` will now allow multiple non-conflicting requests
357
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
358
(Martin von Gagern, #842993)
360
* A call to CHKInventory's filter-method will not result in a
361
DuplicateFileId error, if you move a subfolder and change a file in
363
(Bastian Bowe, #809901)
365
* Branching from a stacked branch no longer does a ``get_parent_map``
366
request for each revisions that is in the stacked-on repository while
367
determining what revisions need to be fetched. This mostly impacts
368
branching initialy into an empty shared repository when the source is
369
not the development focus. (John Arbash Meinel, #388269)
371
* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
372
errors. (Vincent Ladeuil, #822571)
374
* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
375
raised whenever a transport at the drive root was opened on windows.
376
(Martin [gz], #841322)
378
* Fixed loading of external merge tools from config to properly decode
379
command-lines which contain embedded quotes. (Gordon Tyler, #828803)
381
* Rather than an error being raised, a warning is now printed when the
382
current user does not have permission to read a configuration file.
383
(Jelmer Vernooij, #837324)
385
* The pull command will now always use separate connections for the
386
case where the destination is a heavyweight checkout of some remote
387
branch on the same host as the source branch.
388
(Martin von Gagern, #483661)
390
* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
391
operations that use it, like merge, can now create trees without a root.
397
* Release instructions refreshed. (Vincent Ladeuil)
402
* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
403
argument. (Jelmer Vernooij)
405
* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
406
which indicates if the format should be for a lightweight or a
407
heavyweight checkout. (Jelmer Vernooij)
409
* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
412
* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
415
* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
416
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
419
* New method ``InterTree.file_content_matches`` which checks that
420
two files in different trees have the same contents.
423
* New method ``Tree.get_file_verifier`` which allows tree implementations
424
to return non-sha1 checksums to verify files.
425
(Jelmer Vernooij, #720831)
427
* New methods ``get_transport_from_path`` and ``get_transport_from_url``
428
have been added that only support opening from a path or a URL,
429
unlike ``get_transport``. (Jelmer Vernooij)
431
* New registry ``OptionRegistry`` specialized for configuration options.
434
* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
437
* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
438
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
439
2.10 and 2.2.0. (Vincent Ladeuil)
441
* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.
443
* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
444
``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
445
remove ``log.show_one_log`` which was never properly deprecated but wasn't
446
used and is easy to inline if needed. (Vincent Ladeuil)
448
* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
449
deprecated in 2.1.0. (Vincent Ladeuil)
451
* Remove ``TransportListRegistry.set_default_transport``, as the concept of
452
a default transport is currently unused. (Jelmer Vernooij)
454
* Remove ``UIFactory.warn_cross_format_fetch`` and
455
``UIFactory.warn_experimental_format_fetch`` in favor of
456
``UIFactory.show_user_warning``. (Jelmer Vernooij)
458
* ``Tags`` containers can now declare whether they support versioned
459
tags and whether tags can refer to ghost tags.
462
* ``Tags.merge_to`` now returns a dictionary with the updated tags
463
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)
465
* There is a new class `ContentFilterTree` that provides a facade for
466
content filtering. The `filtered` parameter to `export` is deprecated
467
in favor of passing a filtered tree, and the specific exporter plugins
468
no longer support it.
471
* ``Transport`` now has a ``_parsed_url`` attribute instead of
472
separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
473
and ``_path`` attributes. Proxies are provided for the moment but
474
may be removed in the future. (Jelmer Vernooij)
479
* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
480
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
481
is attempted. (Jelmer Vernooij)
483
* New method ``ControlDir._get_selected_branch`` which returns the
484
colocated branch selected using path segment parameters.
485
(Jelmer Vernooij, #380871)
490
* Blackbox tests (including test scripts) can be debugged interactively (see
491
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)
493
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
494
cleanly and reliably allows tests using `BranchBuilder` to construct
495
branches that e.g. rename files out of a directory and unversion that
496
directory in the same revision. Previously some changes were impossible
497
due to the order that `build_snapshot` performs its actions.
500
* Don't require ``os.fdatasync`` to be defined on all supported OSes
501
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)
503
* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
505
* ``LockDir`` can now be run when the local hostname is ``localhost``.
506
(Jelmer Vernooij, #825994)
508
* ``ModuleAvailableFeature`` won't try to import already imported modules,
509
allowing it to be used for modules with side-effects.
510
(Vincent Ladeuil, #712474)
512
* Output time stamps while running ``make check`` to get better timings from
513
pqm. (Vincent Ladeuil, #837926)
515
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
516
just compares the bytes in the dirstate file to its pristine state,
517
rather than opening the WorkingTree and calling ``last_revision()``.
518
This reduces the overall test suite time by about 10% on my laptop.
521
* Update `TestCase.knownFailure` to the testtools way of handling expected
522
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
