*****************************
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)
40
* all input prompts are now char-based when possible, and can be forced to
41
line-based mode by setting the ``BZR_TEXTUI_INPUT`` environment variable
42
to 'line-based'. This replace the previous shelf UI only patch using
43
``INSIDE_EMACS``. (Benoît Pierre)
48
.. Fixes for situations where bzr would previously crash or give incorrect
49
or undesirable results.
51
* ``bzr mkdir --quiet`` now does not print a line for every created
52
directory. (Martin von Gagern, #869915)
54
* ``bzr mv`` does not crash when attempting to move the root of a
55
branch. (Jonathan Riddell, #809728)
57
* ``bzr shelve`` now use ``UIFactory.choose`` for input handling, making
58
it usable when creating a custom ``UIFactory`` implementation. (Benoît
61
* If sending a crash through Apport fails report the Apport failure to
62
bzr.log rather than stderr. (Jonathan Riddell, #766735)
67
.. Improved or updated documentation.
72
.. Changes that may require updates in plugins or other code that uses
75
* ``Branch.revision_history`` is now deprecated. (Jelmer Vernooij, #799519)
77
* New flag ``RepositoryFormat.supports_unreferenced_revisions`` which
78
indicates whether revisions can be present in a repository without
79
being referenced from e.g. a branch history at the same time.
82
* ``UIFactory.choose`` has been added: prompt the user for a list of
83
choices. (Benoît Pierre)
88
.. Major internal changes, unlikely to be visible to users or plugin
89
developers, but interesting for bzr developers.
91
* ``ControlDirFormat`` now has a new method ``supports_transport``
92
which format implementations can use whether or not they can access
93
a control dir over a particular transport. (Jelmer Vernooij)
95
* ``BranchBuilder.build_commit`` now take ``parent_ids`` and
96
``allow_leftmost_as_ghost`` arguments. (Jelmer Vernooij)
101
.. Fixes and changes that are only relevant to bzr's test framework and
102
suite. This can include new facilities for writing tests, fixes to
103
spurious test failures and changes to the way things should be tested.
105
* Ensure TestCase instances are deallocated immediately after running where
106
possible. This greatly reduces the peak resource needs of a full test suite
107
run. The new ``-Euncollected_cases`` selftest flag will add failures if any
108
case which persists pasts its expected lifetime. (Martin Packman, #613247)
114
This is the second beta of the 2.5 series, leading to a 2.5.0 release in
115
February 2012. Beta releases are suitable for everyday use but may cause some
116
incompatibilities with plugins.
118
This release includes more filtering options for ``bzr log``, idle
119
connections handling for ``bzr serve``, a ``development-colo`` experimental
120
format to flesh out the colocated branches UI, better support for foreign
121
formats, enhancements to the config framework and more.
123
This release includes all bug fixed in previous series known at the time of
128
External Compatibility Breaks
129
*****************************
136
* A new ``-O`` standard option (common to all commands) have been added. It
137
provides a value for a config option in the ``-Oname=value`` form that
138
takes precedence over all definitions found in config files. It can be
139
used multiple times to override different options.
140
(Vincent Ladeuil, #491196)
142
* ``bzr log`` now has an option called ``--omit-merges`` to omit
143
those commits that merged branches, i.e. those having more than one
145
In order to avoid confusion, the previous command line option
146
``--include-merges`` has been renamed to ``--include-merged``.
147
The old name of the command line option will still be accepted.
148
The name change also affects ``bzr missing``.
151
* ``bzr serve`` will now disconnect clients if they have not issued an RPC
152
request after 5minutes. On POSIX platforms, this will also happen for
153
``bzr serve --inet``. This can be overridden with the configuration
154
variable ``serve.client_timeout`` or in the command line parameter
155
``bzr serve --client-timeout=X``. Further, it is possible to request
156
``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will
157
finish the current request, and then close the connection.
158
(John Arbash Meinel, #824797, #795025)
160
* The new experimental format ``development-colo`` supports colocated
161
branches. This format will eventually be merged back into the ``2a``
162
format when it has stabilized and there is adequate UI support for
164
(Jelmer Vernooij, #831481)
169
* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
170
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)
172
* ``bzr info -v`` can now be run against branches that don't support
173
``last_revision_info``, in which case the branch information will simply
174
not be displayed. (Jelmer Vernooij)
179
* ``bzr shelve`` can now be used in emacs shells as the input handling is
180
turned into a line-based one when ``INSIDE_EMACS`` is set (which is the
181
case for all recent emacs versions). (Vincent Ladeuil, #856261)
183
* ``bzr tags`` can now be used against remote repositories that do
184
not provide access to the revision graph. (Jelmer Vernooij, #858942)
186
* ``bzr update PATH`` will stop if you seem to be asking it to update
187
anything less than a whole tree, because that's not supported by ``bzr``'s
188
concept that the whole tree has a single basis revision. Previously, it
189
would go ahead and update the whole tree, which was surprising.
190
(Martin Pool, #557886)
192
* Don't crash if ``bzrlib.initialize()`` has not been called while accessing
193
configs. (Vincent Ladeuil, #863401)
195
* Redirects between http and https no longer discard path information
196
in some cases. (Jelmer Vernooij, #853765)
198
* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer
199
reports all tags as changed. (Jelmer Vernooij, #845396)
201
* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is
202
specified that is unknown. (Jelmer Vernooij, #847435)
208
* ``Branch.get_revision_delta`` has been deprecated. Use
209
``Repository.get_revision_delta`` instead. (Jelmer Vernooij, #859712)
211
* Plugins that implement custom protocols for ``bzr serve`` should now
212
also take an argument ``timeout``. This is used by the the bzr protocol
213
to close a connection if a client has been idle for more than X seconds.
214
(Default 5minutes). (John Arbash Meinel)
216
* ``Repository.fileids_altered_by_revision_ids`` has been moved to
217
``VersionedFileRepository`` and is no longer part of the standard
218
``Repository`` interface. (Jelmer Vernooij)
220
* The argument ``include_merges`` to ``missing.find_unmerged`` has
221
been renamed to ``include_merged``. The old name is still supported
222
for now but will cause a deprecation warning. (Martin von Gagern)
224
* The new method ``ControlDirFormat.is_initializable()`` returns a boolean
225
indicating whether or not it is possible to use any of the
226
initialization methods of that format to create a new control dir.
232
* ``Branch`` objects can now use a config stack with the newly introduced
233
``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can
234
be used for the same branch but it's recommended to stick to one for a
240
* Test scripts can now use ``bzr shelve`` and provide their input as
241
complete lines. (Vincent Ladeuil, #856261)
243
* Really corrupt the pack file without depending on a special length or value.
244
(Vincent Ladeuil, #807032)
252
This is the first beta of the 2.5 series, leading up to a 2.5.0
253
release in February 2012.
255
This release includes better support for gpg signing, better support for
256
i18n (mostly command help and error messages), more options to filter ``bzr
257
log`` output, more support for colocated branches ("location,branch=XXX"
258
syntax), better feedback on updated tags for various commands, faster
259
branching into an empty repository, enhancements to the config framework and
262
Beta releases are suitable for everyday use but may cause some
263
incompatibilities with plugins. Some plugins may need small updates to work
266
External Compatibility Breaks
267
*****************************
274
* A ``from_unicode`` parameter can be specified when registering a config
275
option. This implements boolean, integer and list config options when the
276
provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``
277
are used for this parameter. (Vincent Ladeuil)
279
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
280
checks to see if the most recent published source package version for
281
that project is present in the branch tags. This should help developers
282
trust whether the packaging branch is up-to-date and can be used for new
283
changes. The level of verbosity is controlled by the config item
284
``launchpad.packaging_verbosity``. It can be set to one of
291
only display if the branch is out-of-date
294
also display single-line up-to-date and missing,
298
(default) display multi-line content for all states
301
(John Arbash Meinel, #609187, #812928)
303
* Add a config option gpg_signing_key for setting which GPG key should
304
be used to sign commits. Also default to using the gpg user identity
305
which matches user_email() as set by whoami.
306
(Jonathan Riddell, #68501)
308
* An ``invalid`` parameter can be specified when registering a config option
309
to decide what should be done when invalid values are
310
encountered. 'warning' and 'error' will respectively emit a warning and
311
ignore the value or errors out. (Vincent Ladeuil)
313
* bzr add now skips large files in recursive mode. The default "large"
314
size is 20MB, and is configurable via the add.maximum_file_size
315
option. A value of 0 disables skipping. Named items passed to add are
316
never skipped. (Shannon Weyrick, #54624)
318
* ``bzr help configuration/<option>`` display the help for ``option`` for
319
all registered configuration options. (Vincent Ladeuil, #747050)
321
* ``bzr log -m`` now matches message, author, committer and bugs instead
322
of just matching the message. ``--message`` keeps its original meaning,
323
while ``--match-message, --match-author, --match-committer`` and
324
``--match-bugs`` match each of those fields. (Jacek Sieka)
326
* ``config.Option`` can now declare ``default_from_env``, a list of
327
environment variables to get a default value from. (Vincent Ladeuil)
329
* ``config.NameMatcher`` can be used to implement config stores and stacks
330
that need to provide specific option values for arbitrary unique IDs (svn
331
repository UUIDs, etc). (Vincent Ladeuil, #843638)
333
* New builtin ``bzr branches`` command, which lists all colocated branches
334
in a directory. (Jelmer Vernooij, #826820)
336
* Relative local paths can now be specified in URL syntax by using the
337
"file:" prefix. (Jelmer Vernooij)
339
* Report commits signed with expired keys in ``verify-signatures``.
340
(Jonathan Riddell, #804254)
342
* Translations are now enabled for command help, errors and globally
343
for any message using ``gettext`` given on output. (Jonathan Riddell,
349
* ``bzr add`` will now warn about nested subtrees that are skipped.
350
(Jelmer Vernooij, #187342)
352
* ``bzr commit -m ''`` can now be used to force an empty commit message.
353
Entering an empty commit message in the message editor still triggers
354
an error. (Jelmer Vernooij)
356
* ``bzr pull`` will now mention how many tags it has updated.
357
(Jelmer Vernooij, #164450)
359
* ``bzr tag`` no longer errors if a tag already exists but refers to the
360
same revision, and will mention when a tag has been updated
361
rather than created. (Jelmer Vernooij, #381203)
363
* ``bzr uncommit`` will now remove tags that refer to removed revisions.
364
The ``--keep-tags`` option can be used to prevent this behaviour.
365
(Jelmer Vernooij, #605814)
367
* Do not run i18n initialisation twice. (Jonathan Riddell)
369
* Install translation .mo files. (Jonathan Riddell)
371
* Locations printed by ``bzr upgrade`` are now formatted before display.
374
* ``Repository.get_parent_map`` now estimates the size of the returned
375
content more accurately. This means that we get closer to the desired
376
64kB/request. For repositories converted from svn, this can be an
377
improvement of approx 5:1 in round trips to discover the whole history.
380
* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
381
if no bug tracker was specified on the command line.
382
(Jelmer Vernooij, #334860)
384
* Use ``gettext.NullTranslations`` in i18n to allow use of i18n even when
385
translations are not turned on. (Jonathan Riddell)
390
* ``bzr commit`` now correctly reports missing files as "removed", not
391
"modified". (Jelmer Vernooij, #553955)
393
* ``bzr reconfigure`` will now allow multiple non-conflicting requests
394
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
395
(Martin von Gagern, #842993)
397
* A call to CHKInventory's filter-method will not result in a
398
DuplicateFileId error, if you move a subfolder and change a file in
400
(Bastian Bowe, #809901)
402
* Branching from a stacked branch no longer does a ``get_parent_map``
403
request for each revisions that is in the stacked-on repository while
404
determining what revisions need to be fetched. This mostly impacts
405
branching initialy into an empty shared repository when the source is
406
not the development focus. (John Arbash Meinel, #388269)
408
* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
409
errors. (Vincent Ladeuil, #822571)
411
* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
412
raised whenever a transport at the drive root was opened on windows.
413
(Martin [gz], #841322)
415
* Fixed loading of external merge tools from config to properly decode
416
command-lines which contain embedded quotes. (Gordon Tyler, #828803)
418
* Rather than an error being raised, a warning is now printed when the
419
current user does not have permission to read a configuration file.
420
(Jelmer Vernooij, #837324)
422
* The pull command will now always use separate connections for the
423
case where the destination is a heavyweight checkout of some remote
424
branch on the same host as the source branch.
425
(Martin von Gagern, #483661)
427
* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
428
operations that use it, like merge, can now create trees without a root.
434
* Release instructions refreshed. (Vincent Ladeuil)
439
* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
440
argument. (Jelmer Vernooij)
442
* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
443
which indicates if the format should be for a lightweight or a
444
heavyweight checkout. (Jelmer Vernooij)
446
* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
449
* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
452
* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
453
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
456
* New method ``InterTree.file_content_matches`` which checks that
457
two files in different trees have the same contents.
460
* New method ``Tree.get_file_verifier`` which allows tree implementations
461
to return non-sha1 checksums to verify files.
462
(Jelmer Vernooij, #720831)
464
* New methods ``get_transport_from_path`` and ``get_transport_from_url``
465
have been added that only support opening from a path or a URL,
466
unlike ``get_transport``. (Jelmer Vernooij)
468
* New registry ``OptionRegistry`` specialized for configuration options.
471
* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
474
* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
475
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
476
2.10 and 2.2.0. (Vincent Ladeuil)
478
* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.
480
* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
481
``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
482
remove ``log.show_one_log`` which was never properly deprecated but wasn't
483
used and is easy to inline if needed. (Vincent Ladeuil)
485
* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
486
deprecated in 2.1.0. (Vincent Ladeuil)
488
* Remove ``TransportListRegistry.set_default_transport``, as the concept of
489
a default transport is currently unused. (Jelmer Vernooij)
491
* Remove ``UIFactory.warn_cross_format_fetch`` and
492
``UIFactory.warn_experimental_format_fetch`` in favor of
493
``UIFactory.show_user_warning``. (Jelmer Vernooij)
495
* ``Tags`` containers can now declare whether they support versioned
496
tags and whether tags can refer to ghost tags.
499
* ``Tags.merge_to`` now returns a dictionary with the updated tags
500
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)
502
* There is a new class `ContentFilterTree` that provides a facade for
503
content filtering. The `filtered` parameter to `export` is deprecated
504
in favor of passing a filtered tree, and the specific exporter plugins
505
no longer support it.
508
* ``Transport`` now has a ``_parsed_url`` attribute instead of
509
separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
510
and ``_path`` attributes. Proxies are provided for the moment but
511
may be removed in the future. (Jelmer Vernooij)
516
* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
517
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
518
is attempted. (Jelmer Vernooij)
520
* New method ``ControlDir._get_selected_branch`` which returns the
521
colocated branch selected using path segment parameters.
522
(Jelmer Vernooij, #380871)
527
* Blackbox tests (including test scripts) can be debugged interactively (see
528
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)
530
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
531
cleanly and reliably allows tests using `BranchBuilder` to construct
532
branches that e.g. rename files out of a directory and unversion that
533
directory in the same revision. Previously some changes were impossible
534
due to the order that `build_snapshot` performs its actions.
537
* Don't require ``os.fdatasync`` to be defined on all supported OSes
538
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)
540
* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
542
* ``LockDir`` can now be run when the local hostname is ``localhost``.
543
(Jelmer Vernooij, #825994)
545
* ``ModuleAvailableFeature`` won't try to import already imported modules,
546
allowing it to be used for modules with side-effects.
547
(Vincent Ladeuil, #712474)
549
* Output time stamps while running ``make check`` to get better timings from
550
pqm. (Vincent Ladeuil, #837926)
552
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
553
just compares the bytes in the dirstate file to its pristine state,
554
rather than opening the WorkingTree and calling ``last_revision()``.
555
This reduces the overall test suite time by about 10% on my laptop.
558
* Update `TestCase.knownFailure` to the testtools way of handling expected
559
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
