External Compatibility Breaks

*****************************
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.
73
* Ensure TestCase instances are deallocated immediately after running where
74
possible. This greatly reduces the peak resource needs of a full test suite
75
run. The new ``-Euncollected_cases`` selftest flag will add failures if any
76
case which persists pasts its expected lifetime. (Martin Packman, #613247)
82
This is the second beta of the 2.5 series, leading to a 2.5.0 release in
83
February 2012. Beta releases are suitable for everyday use but may cause some
84
incompatibilities with plugins.
86
This release includes more filtering options for ``bzr log``, idle
87
connections handling for ``bzr serve``, a ``development-colo`` experimental
88
format to flesh out the colocated branches UI, better support for foreign
89
formats, enhancements to the config framework and more.
91
This release includes all bug fixed in previous series known at the time of
96
External Compatibility Breaks
97
*****************************
104
* A new ``-O`` standard option (common to all commands) have been added. It
105
provides a value for a config option in the ``-Oname=value`` form that
106
takes precedence over all definitions found in config files. It can be
107
used multiple times to override different options.
108
(Vincent Ladeuil, #491196)
110
* ``bzr log`` now has an option called ``--omit-merges`` to omit
111
those commits that merged branches, i.e. those having more than one
113
In order to avoid confusion, the previous command line option
114
``--include-merges`` has been renamed to ``--include-merged``.
115
The old name of the command line option will still be accepted.
116
The name change also affects ``bzr missing``.
119
* ``bzr serve`` will now disconnect clients if they have not issued an RPC
120
request after 5minutes. On POSIX platforms, this will also happen for
121
``bzr serve --inet``. This can be overridden with the configuration
122
variable ``serve.client_timeout`` or in the command line parameter
123
``bzr serve --client-timeout=X``. Further, it is possible to request
124
``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will
125
finish the current request, and then close the connection.
126
(John Arbash Meinel, #824797, #795025)
128
* The new experimental format ``development-colo`` supports colocated
129
branches. This format will eventually be merged back into the ``2a``
130
format when it has stabilized and there is adequate UI support for
132
(Jelmer Vernooij, #831481)
137
* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
138
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)
140
* ``bzr info -v`` can now be run against branches that don't support
141
``last_revision_info``, in which case the branch information will simply
142
not be displayed. (Jelmer Vernooij)
147
* ``bzr shelve`` can now be used in emacs shells as the input handling is
148
turned into a line-based one when ``INSIDE_EMACS`` is set (which is the
149
case for all recent emacs versions). (Vincent Ladeuil, #856261)
151
* ``bzr tags`` can now be used against remote repositories that do
152
not provide access to the revision graph. (Jelmer Vernooij, #858942)
154
* ``bzr update PATH`` will stop if you seem to be asking it to update
155
anything less than a whole tree, because that's not supported by ``bzr``'s
156
concept that the whole tree has a single basis revision. Previously, it
157
would go ahead and update the whole tree, which was surprising.
158
(Martin Pool, #557886)
160
* Don't crash if ``bzrlib.initialize()`` has not been called while accessing
161
configs. (Vincent Ladeuil, #863401)
163
* Redirects between http and https no longer discard path information
164
in some cases. (Jelmer Vernooij, #853765)
166
* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer
167
reports all tags as changed. (Jelmer Vernooij, #845396)
169
* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is
170
specified that is unknown. (Jelmer Vernooij, #847435)
176
* ``Branch.get_revision_delta`` has been deprecated. Use
177
``Repository.get_revision_delta`` instead. (Jelmer Vernooij, #859712)
179
* Plugins that implement custom protocols for ``bzr serve`` should now
180
also take an argument ``timeout``. This is used by the the bzr protocol
181
to close a connection if a client has been idle for more than X seconds.
182
(Default 5minutes). (John Arbash Meinel)
184
* ``Repository.fileids_altered_by_revision_ids`` has been moved to
185
``VersionedFileRepository`` and is no longer part of the standard
186
``Repository`` interface. (Jelmer Vernooij)
188
* The argument ``include_merges`` to ``missing.find_unmerged`` has
189
been renamed to ``include_merged``. The old name is still supported
190
for now but will cause a deprecation warning. (Martin von Gagern)
192
* The new method ``ControlDirFormat.is_initializable()`` returns a boolean
193
indicating whether or not it is possible to use any of the
194
initialization methods of that format to create a new control dir.
200
* ``Branch`` objects can now use a config stack with the newly introduced
201
``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can
202
be used for the same branch but it's recommended to stick to one for a
208
* Test scripts can now use ``bzr shelve`` and provide their input as
209
complete lines. (Vincent Ladeuil, #856261)
211
* Really corrupt the pack file without depending on a special length or value.
212
(Vincent Ladeuil, #807032)
220
This is the first beta of the 2.5 series, leading up to a 2.5.0
221
release in February 2012.
223
This release includes better support for gpg signing, better support for
224
i18n (mostly command help and error messages), more options to filter ``bzr
225
log`` output, more support for colocated branches ("location,branch=XXX"
226
syntax), better feedback on updated tags for various commands, faster
227
branching into an empty repository, enhancements to the config framework and
230
Beta releases are suitable for everyday use but may cause some
231
incompatibilities with plugins. Some plugins may need small updates to work
234
External Compatibility Breaks
235
*****************************
242
* A ``from_unicode`` parameter can be specified when registering a config
243
option. This implements boolean, integer and list config options when the
244
provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``
245
are used for this parameter. (Vincent Ladeuil)
247
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
248
checks to see if the most recent published source package version for
249
that project is present in the branch tags. This should help developers
250
trust whether the packaging branch is up-to-date and can be used for new
251
changes. The level of verbosity is controlled by the config item
252
``launchpad.packaging_verbosity``. It can be set to one of
259
only display if the branch is out-of-date
262
also display single-line up-to-date and missing,
266
(default) display multi-line content for all states
269
(John Arbash Meinel, #609187, #812928)
271
* Add a config option gpg_signing_key for setting which GPG key should
272
be used to sign commits. Also default to using the gpg user identity
273
which matches user_email() as set by whoami.
274
(Jonathan Riddell, #68501)
276
* An ``invalid`` parameter can be specified when registering a config option
277
to decide what should be done when invalid values are
278
encountered. 'warning' and 'error' will respectively emit a warning and
279
ignore the value or errors out. (Vincent Ladeuil)
281
* bzr add now skips large files in recursive mode. The default "large"
282
size is 20MB, and is configurable via the add.maximum_file_size
283
option. A value of 0 disables skipping. Named items passed to add are
284
never skipped. (Shannon Weyrick, #54624)
286
* ``bzr help configuration/<option>`` display the help for ``option`` for
287
all registered configuration options. (Vincent Ladeuil, #747050)
289
* ``bzr log -m`` now matches message, author, committer and bugs instead
290
of just matching the message. ``--message`` keeps its original meaning,
291
while ``--match-message, --match-author, --match-committer`` and
292
``--match-bugs`` match each of those fields. (Jacek Sieka)
294
* ``config.Option`` can now declare ``default_from_env``, a list of
295
environment variables to get a default value from. (Vincent Ladeuil)
297
* ``config.NameMatcher`` can be used to implement config stores and stacks
298
that need to provide specific option values for arbitrary unique IDs (svn
299
repository UUIDs, etc). (Vincent Ladeuil, #843638)
301
* New builtin ``bzr branches`` command, which lists all colocated branches
302
in a directory. (Jelmer Vernooij, #826820)
304
* Relative local paths can now be specified in URL syntax by using the
305
"file:" prefix. (Jelmer Vernooij)
307
* Report commits signed with expired keys in ``verify-signatures``.
308
(Jonathan Riddell, #804254)
310
* Translations are now enabled for command help, errors and globally
311
for any message using ``gettext`` given on output. (Jonathan Riddell,
317
* ``bzr add`` will now warn about nested subtrees that are skipped.
318
(Jelmer Vernooij, #187342)
320
* ``bzr commit -m ''`` can now be used to force an empty commit message.
321
Entering an empty commit message in the message editor still triggers
322
an error. (Jelmer Vernooij)
324
* ``bzr pull`` will now mention how many tags it has updated.
325
(Jelmer Vernooij, #164450)
327
* ``bzr tag`` no longer errors if a tag already exists but refers to the
328
same revision, and will mention when a tag has been updated
329
rather than created. (Jelmer Vernooij, #381203)
331
* ``bzr uncommit`` will now remove tags that refer to removed revisions.
332
The ``--keep-tags`` option can be used to prevent this behaviour.
333
(Jelmer Vernooij, #605814)
335
* Do not run i18n initialisation twice. (Jonathan Riddell)
337
* Install translation .mo files. (Jonathan Riddell)
339
* Locations printed by ``bzr upgrade`` are now formatted before display.
342
* ``Repository.get_parent_map`` now estimates the size of the returned
343
content more accurately. This means that we get closer to the desired
344
64kB/request. For repositories converted from svn, this can be an
345
improvement of approx 5:1 in round trips to discover the whole history.
348
* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
349
if no bug tracker was specified on the command line.
350
(Jelmer Vernooij, #334860)
352
* Use ``gettext.NullTranslations`` in i18n to allow use of i18n even when
353
translations are not turned on. (Jonathan Riddell)
358
* ``bzr commit`` now correctly reports missing files as "removed", not
359
"modified". (Jelmer Vernooij, #553955)
361
* ``bzr reconfigure`` will now allow multiple non-conflicting requests
362
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
363
(Martin von Gagern, #842993)
365
* A call to CHKInventory's filter-method will not result in a
366
DuplicateFileId error, if you move a subfolder and change a file in
368
(Bastian Bowe, #809901)
370
* Branching from a stacked branch no longer does a ``get_parent_map``
371
request for each revisions that is in the stacked-on repository while
372
determining what revisions need to be fetched. This mostly impacts
373
branching initialy into an empty shared repository when the source is
374
not the development focus. (John Arbash Meinel, #388269)
376
* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
377
errors. (Vincent Ladeuil, #822571)
379
* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
380
raised whenever a transport at the drive root was opened on windows.
381
(Martin [gz], #841322)
383
* Fixed loading of external merge tools from config to properly decode
384
command-lines which contain embedded quotes. (Gordon Tyler, #828803)
386
* Rather than an error being raised, a warning is now printed when the
387
current user does not have permission to read a configuration file.
388
(Jelmer Vernooij, #837324)
390
* The pull command will now always use separate connections for the
391
case where the destination is a heavyweight checkout of some remote
392
branch on the same host as the source branch.
393
(Martin von Gagern, #483661)
395
* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
396
operations that use it, like merge, can now create trees without a root.
402
* Release instructions refreshed. (Vincent Ladeuil)
407
* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
408
argument. (Jelmer Vernooij)
410
* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
411
which indicates if the format should be for a lightweight or a
412
heavyweight checkout. (Jelmer Vernooij)
414
* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
417
* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
420
* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
421
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
424
* New method ``InterTree.file_content_matches`` which checks that
425
two files in different trees have the same contents.
428
* New method ``Tree.get_file_verifier`` which allows tree implementations
429
to return non-sha1 checksums to verify files.
430
(Jelmer Vernooij, #720831)
432
* New methods ``get_transport_from_path`` and ``get_transport_from_url``
433
have been added that only support opening from a path or a URL,
434
unlike ``get_transport``. (Jelmer Vernooij)
436
* New registry ``OptionRegistry`` specialized for configuration options.
439
* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
442
* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
443
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
444
2.10 and 2.2.0. (Vincent Ladeuil)
446
* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.
448
* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
449
``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
450
remove ``log.show_one_log`` which was never properly deprecated but wasn't
451
used and is easy to inline if needed. (Vincent Ladeuil)
453
* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
454
deprecated in 2.1.0. (Vincent Ladeuil)
456
* Remove ``TransportListRegistry.set_default_transport``, as the concept of
457
a default transport is currently unused. (Jelmer Vernooij)
459
* Remove ``UIFactory.warn_cross_format_fetch`` and
460
``UIFactory.warn_experimental_format_fetch`` in favor of
461
``UIFactory.show_user_warning``. (Jelmer Vernooij)
463
* ``Tags`` containers can now declare whether they support versioned
464
tags and whether tags can refer to ghost tags.
467
* ``Tags.merge_to`` now returns a dictionary with the updated tags
468
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)
470
* There is a new class `ContentFilterTree` that provides a facade for
471
content filtering. The `filtered` parameter to `export` is deprecated
472
in favor of passing a filtered tree, and the specific exporter plugins
473
no longer support it.
476
* ``Transport`` now has a ``_parsed_url`` attribute instead of
477
separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
478
and ``_path`` attributes. Proxies are provided for the moment but
479
may be removed in the future. (Jelmer Vernooij)
484
* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
485
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
486
is attempted. (Jelmer Vernooij)
488
* New method ``ControlDir._get_selected_branch`` which returns the
489
colocated branch selected using path segment parameters.
490
(Jelmer Vernooij, #380871)
495
* Blackbox tests (including test scripts) can be debugged interactively (see
496
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)
498
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
499
cleanly and reliably allows tests using `BranchBuilder` to construct
500
branches that e.g. rename files out of a directory and unversion that
501
directory in the same revision. Previously some changes were impossible
502
due to the order that `build_snapshot` performs its actions.
505
* Don't require ``os.fdatasync`` to be defined on all supported OSes
506
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)
508
* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
510
* ``LockDir`` can now be run when the local hostname is ``localhost``.
511
(Jelmer Vernooij, #825994)
513
* ``ModuleAvailableFeature`` won't try to import already imported modules,
514
allowing it to be used for modules with side-effects.
515
(Vincent Ladeuil, #712474)
517
* Output time stamps while running ``make check`` to get better timings from
518
pqm. (Vincent Ladeuil, #837926)
520
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
521
just compares the bytes in the dirstate file to its pristine state,
522
rather than opening the WorkingTree and calling ``last_revision()``.
523
This reduces the overall test suite time by about 10% on my laptop.
526
* Update `TestCase.knownFailure` to the testtools way of handling expected
527
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
