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
* ``bzr serve`` will now disconnect clients if they have not issued an RPC
24
request after 5minutes. On POSIX platforms, this will also happen for
25
``bzr serve --inet``. This can be overridden with the configuration
26
variable ``serve.client_timeout`` or in the command line parameter
27
``bzr serve --client-timeout=X``. Further, it is possible to request
28
``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will
29
finish the current request, and then close the connection.
30
(John Arbash Meinel, #824797, #795025)
36
.. Improvements to existing commands, especially improved performance
37
or memory usage, or better results.
39
* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
40
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)
45
.. Fixes for situations where bzr would previously crash or give incorrect
46
or undesirable results.
48
* Redirects between http and https no longer discard path information
49
in some cases. (Jelmer Vernooij, #853765)
51
* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer
52
reports all tags as changed. (Jelmer Vernooij, #845396)
54
* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is
55
specified that is unknown. (Jelmer Vernooij, #847435)
60
.. Improved or updated documentation.
65
.. Changes that may require updates in plugins or other code that uses
68
* The new method ``ControlDirFormat.is_initializable()`` returns a boolean
69
indicating whether or not it is possible to use any of the
70
initialization methods of that format to create a new control dir.
76
.. Major internal changes, unlikely to be visible to users or plugin
77
developers, but interesting for bzr developers.
79
* ``Branch`` objects can now use a config stack with the newly introduced
80
``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can
81
be used for the same branch but it's recommended to stick to one for a
87
.. Fixes and changes that are only relevant to bzr's test framework and
88
suite. This can include new facilities for writing tests, fixes to
89
spurious test failures and changes to the way things should be tested.
91
* Really corrupt the pack file without depending on a special length or value.
92
(Vincent Ladeuil, #807032)
100
This is the first beta of the 2.5 series, leading up to a 2.5.0
101
release in February 2012. Beta releases are suitable for everyday use
102
but may cause some incompatibilities with plugins. Some plugins may need
103
small updates to work with 2.5b1.

External Compatibility Breaks
106
*****************************
113
* A ``from_unicode`` parameter can be specified when registering a config
114
option. This implements boolean, integer and list config options when the
115
provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``
116
are used for this parameter. (Vincent Ladeuil)
118
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
119
checks to see if the most recent published source package version for
120
that project is present in the branch tags. This should help developers
121
trust whether the packaging branch is up-to-date and can be used for new
122
changes. The level of verbosity is controlled by the config item
123
``launchpad.packaging_verbosity``. It can be set to one of
130
only display if the branch is out-of-date
133
also display single-line up-to-date and missing,
137
(default) display multi-line content for all states
140
(John Arbash Meinel, #609187, #812928)
142
* Add a config option gpg_signing_key for setting which GPG key should
143
be used to sign commits. Also default to using the gpg user identity
144
which matches user_email() as set by whoami.
145
(Jonathan Riddell, #68501)
147
* An ``invalid`` parameter can be specified when registering a config option
148
to decide what should be done when invalid values are
149
encountered. 'warning' and 'error' will respectively emit a warning and
150
ignore the value or errors out. (Vincent Ladeuil)
152
* bzr add now skips large files in recursive mode. The default "large"
153
size is 20MB, and is configurable via the add.maximum_file_size
154
option. A value of 0 disables skipping. Named items passed to add are
155
never skipped. (Shannon Weyrick, #54624)
157
* ``bzr help configuration/<option>`` display the help for ``option`` for
158
all registered configuration options. (Vincent Ladeuil, #747050)
160
* ``bzr log -m`` now matches message, author, committer and bugs instead
161
of just matching the message. ``--message`` keeps its original meaning,
162
while ``--match-message, --match-author, --match-committer`` and
163
``--match-bugs`` match each of those fields. (Jacek Sieka)
165
* ``bzr log`` now has an option called ``--omit-merges`` to ommit
166
those commits that merged branches, i.e. those having more than one
168
In order to avoid confusion, the previous command line option
169
``--include-merges`` has been renamed to ``--include-merged``.
170
The old name of the command line option will still be accepted.
171
The name change also affects ``bzr missing``.
174
* ``config.Option`` can now declare ``default_from_env``, a list of
175
environment variables to get a default value from. (Vincent Ladeuil)
177
* ``config.NameMatcher`` can be used to implement config stores and stacks
178
that need to provide specific option values for arbitrary unique IDs (svn
179
repository UUIDs, etc). (Vincent Ladeuil, #843638)
181
* New builtin ``bzr branches`` command, which lists all colocated branches
182
in a directory. (Jelmer Vernooij, #826820)
184
* Relative local paths can now be specified in URL syntax by using the
185
"file:" prefix. (Jelmer Vernooij)
187
* Report commits signed with expired keys in ``verify-signatures``.
188
(Jonathan Riddell, #804254)
190
* Translations are now enabled for command help, errors and globally
191
for any message using gettext given on output. (Jonathan Riddell,
197
* ``bzr add`` will now warn about nested subtrees that are skipped.
198
(Jelmer Vernooij, #187342)
200
* ``bzr commit -m ''`` can now be used to force an empty commit message.
201
Entering an empty commit message in the message editor still triggers
202
an error. (Jelmer Vernooij)
204
* ``bzr pull`` will now mention how many tags it has updated.
205
(Jelmer Vernooij, #164450)
207
* ``bzr tag`` no longer errors if a tag already exists but refers to the
208
same revision, and will mention when a tag has been updated
209
rather than created. (Jelmer Vernooij, #381203)
211
* ``bzr uncommit`` will now remove tags that refer to removed revisions.
212
The ``--keep-tags`` option can be used to prevent this behaviour.
213
(Jelmer Vernooij, #605814)
215
* Do not run i18n initialisation twice. (Jonathan Riddell)
217
* Install translation .mo files. (Jonathan Riddell)
219
* Locations printed by ``bzr upgrade`` are now formatted before display.
222
* ``Repository.get_parent_map`` now estimates the size of the returned
223
content more accurately. This means that we get closer to the desired
224
64kB/request. For repositories converted from svn, this can be an
225
improvement of approx 5:1 in round trips to discover the whole history.
228
* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
229
if no bug tracker was specified on the command line.
230
(Jelmer Vernooij, #334860)
232
* Use gettext.NullTranslations in i18n to allow use of i18n even when
233
translations are not turned on. (Jonathan Riddell)
238
* ``bzr commit`` now correctly reports missing files as "removed", not
239
"modified". (Jelmer Vernooij, #553955)
241
* ``bzr reconfigure`` will now allow multiple non-conflicting requests
242
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
243
(Martin von Gagern, #842993)
245
* A call to CHKInventory's filter-method will not result in a
246
DuplicateFileId error, if you move a subfolder and change a file in
248
(Bastian Bowe, #809901)
250
* Branching from a stacked branch no longer does a ``get_parent_map``
251
request for each revisions that is in the stacked-on repository while
252
determining what revisions need to be fetched. This mostly impacts
253
branching initialy into an empty shared repository when the source is
254
not the development focus. (John Arbash Meinel, #388269)
256
* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
257
errors. (Vincent Ladeuil, #822571)
259
* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
260
raised whenever a transport at the drive root was opened on windows.
261
(Martin [gz], #841322)
263
* Fixed loading of external merge tools from config to properly decode
264
command-lines which contain embedded quotes. (Gordon Tyler, #828803)
266
* Rather than an error being raised, a warning is now printed when the
267
current user does not have permission to read a configuration file.
268
(Jelmer Vernooij, #837324)
270
* The pull command will now always use separate connections for the
271
case where the destination is a heavyweight checkout of some remote
272
branch on the same host as the source branch.
273
(Martin von Gagern, #483661)
275
* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
276
operations that use it, like merge, can now create trees without a root.
282
* Release instructions refreshed. (Vincent Ladeuil)
287
* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
288
argument. (Jelmer Vernooij)
290
* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
291
which indicates if the format should be for a lightweight or a
292
heavyweight checkout. (Jelmer Vernooij)
294
* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
297
* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
300
* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
301
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
304
* New method ``InterTree.file_content_matches`` which checks that
305
two files in different trees have the same contents.
308
* New method ``Tree.get_file_verifier`` which allows tree implementations
309
to return non-sha1 checksums to verify files.
310
(Jelmer Vernooij, #720831)
312
* New methods ``get_transport_from_path`` and ``get_transport_from_url``
313
have been added that only support opening from a path or a URL,
314
unlike ``get_transport``. (Jelmer Vernooij)
316
* New registry ``OptionRegistry`` specialized for configuration options.
319
* Plugins that implement custom protocols for ``bzr serve`` should now
320
also take an argument ``timeout``. This is used by the the bzr protocol
321
to close a connection if a client has been idle for more than X seconds.
322
(Default 5minutes). (John Arbash Meinel)
324
* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
327
* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
328
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
329
2.10 and 2.2.0. (Vincent Ladeuil)
331
* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.
333
* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
334
``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
335
remove ``log.show_one_log`` which was never properly deprecated but wasn't
336
used and is easy to inline if needed. (Vincent Ladeuil)
338
* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
339
deprecated in 2.1.0. (Vincent Ladeuil)
341
* Remove ``TransportListRegistry.set_default_transport``, as the concept of
342
a default transport is currently unused. (Jelmer Vernooij)
344
* Remove ``UIFactory.warn_cross_format_fetch`` and
345
``UIFactory.warn_experimental_format_fetch`` in favor of
346
``UIFactory.show_user_warning``. (Jelmer Vernooij)
348
* ``Tags`` containers can now declare whether they support versioned
349
tags and whether tags can refer to ghost tags.
352
* ``Tags.merge_to`` now returns a dictionary with the updated tags
353
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)
355
* There is a new class `ContentFilterTree` that provides a facade for
356
content filtering. The `filtered` parameter to `export` is deprecated
357
in favor of passing a filtered tree, and the specific exporter plugins
358
no longer support it.
361
* ``Transport`` now has a ``_parsed_url`` attribute instead of
362
separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
363
and ``_path`` attributes. Proxies are provided for the moment but
364
may be removed in the future. (Jelmer Vernooij)
366
* The argument ``include_merges`` to ``missing.find_unmerged`` has
367
been renamed to ``include_merged``. The old name is still supported
368
for now but will cause a deprecation warning. (Martin von Gagern)
374
* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
375
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
376
is attempted. (Jelmer Vernooij)
378
* New method ``ControlDir._get_selected_branch`` which returns the
379
colocated branch selected using path segment parameters.
380
(Jelmer Vernooij, #380871)
385
* Blackbox tests (including test scripts) can be debugged interactively (see
386
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)
388
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
389
cleanly and reliably allows tests using `BranchBuilder` to construct
390
branches that e.g. rename files out of a directory and unversion that
391
directory in the same revision. Previously some changes were impossible
392
due to the order that `build_snapshot` performs its actions.
395
* Don't require ``os.fdatasync`` to be defined on all supported OSes
396
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)
398
* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
400
* ``LockDir`` can now be run when the local hostname is ``localhost``.
401
(Jelmer Vernooij, #825994)
403
* ``ModuleAvailableFeature`` won't try to import already imported modules,
404
allowing it to be used for modules with side-effects.
405
(Vincent Ladeuil, #712474)
407
* Output time stamps while running ``make check`` to get better timings from
408
pqm. (Vincent Ladeuil, #837926)
410
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
411
just compares the bytes in the dirstate file to its pristine state,
412
rather than opening the WorkingTree and calling ``last_revision()``.
413
This reduces the overall test suite time by about 10% on my laptop.
416
* Update `TestCase.knownFailure` to the testtools way of handling expected
417
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
