*****************************
16
.. These may require users to change the way they use Bazaar.
21
.. New commands, options, etc that users may wish to try out.
26
.. Improvements to existing commands, especially improved performance
27
or memory usage, or better results.
29
* ``bzr branches`` will now also list sibling branches when
30
the current location is a lightweight checkout of a branch in
31
a shared repository. (Jelmer Vernooij)
36
.. Fixes for situations where bzr would previously crash or give incorrect
37
or undesirable results.
39
* Connecting with HTTPS via HTTP now correctly uses the host name of the
40
destination rather than the proxy when checking certificates.
41
(Martin Packman, #944696)
43
* Fixed merge tool availability checking and invocation to search the
44
Windows App Path registry in addition to the PATH. (Gordon Tyler, #939605)
46
* Make sure configuration options can provide their own help topic.
47
(Jelmer Vernooij, #941672)
52
* The alpha-quality texinfo sphinx builder has been deprecated. Sphinx >=
53
1.1.2 now provides a better one. Most of the documentation can now be
54
generated to the texinfo format with ``make texinfo-sphinx``. This will
55
generate both the ``.texi`` files and the ``.info`` ones.
56
(Vincent Ladeuil, #940164)
61
.. Changes that may require updates in plugins or other code that uses
67
.. Major internal changes, unlikely to be visible to users or plugin
68
developers, but interesting for bzr developers.
73
.. Fixes and changes that are only relevant to bzr's test framework and
74
suite. This can include new facilities for writing tests, fixes to
75
spurious test failures and changes to the way things should be tested.
84
This release marks the start of a new long-term-stable series. From here, we
85
will only make bugfix releases on the 2.5 series (2.5.1, etc, and support it
86
until April 2017), while 2.6 will become our new development series.
88
This is a bugfix and polish release over the 2.4 series, with a large number
89
of bugs fixed (~170 for the 2.5 series alone). The 2.5 series provides a
90
faster smart protocol implementation for many operations, basic support for
91
colocated branches. We have started translating bzr with the 2.5 series:
92
https://translations.launchpad.net/bzr, more than 20 languages have already
93
been registered but these are the early days, contributions welcome.
95
Only a few bugfixes have been included since 2.5b6 so all known fixed bugs
98
Users are encouraged to upgrade from the other stable series.

*****************************
114
* The names of colocated branches are used as branch nicks if no nick is
115
specified. (Aaron Bentley)
120
* Show locks in ``bzr info`` on control directories without a
121
repository. (Jelmer Vernooij, #936767)
123
* Disable ssl certificate verification on osx and windows until a native
124
access to the the root certificates is provided there.
125
(Vincent Ladeuil, #929179)
130
* Stop depending on the particular CPython ordering of dictionary keys
131
when testing the result of BzrDir.get_branches.
139
This is the sixth (and last (really)) beta of the 2.5 series, leading to a
140
2.5.0 release in March 2012. Beta releases are suitable for everyday use
141
but may cause some incompatibilities with plugins.
143
This introduces the support for colocated branches into the '2a' format in a
144
backward compatible way, fix more glitches in the colocated UI, verify https
145
certificates for the urllib https client implementation, fix some more
146
unicode issues and more.

152
*****************************
159
* Support for colocated branches is now available in the default
160
format ("2a"). (Jelmer Vernooij)
165
* ``bzr switch -b`` in a standalone tree will now create a colocated branch.
166
(Jelmer Vernooij, #918197)
168
* ``bzr info`` now reports when there are present (but unused) colocated
169
branches. (Jelmer Vernooij, #891646)
171
* Checkouts can now be into target directories that already have
172
a control directory (but no branch or working tree).
173
(Jelmer Vernooij, #913980)
175
* Checkouts of colocated branches are now always lightweight.
176
(Jelmer Vernooij, #918828)
178
* Colocated branches can now have names including forward slashes, to
179
allow for namespaces. (Jelmer Vernooij, #907980)
181
* New HPSS call for ``BzrDir.get_branches``. (Jelmer Vernooij, #894460)
186
* ``bzr branch`` now fetches revisions when branching into an empty
187
control directory. (Jelmer Vernooij, #905594)
189
* A sane default is provided for ``ssl.ca_certs`` which should points to the
190
Certificate Authority bundle for supported platforms.
191
(Vincent Ladeuil, #920455)
193
* ``bzr branch`` generates correct target branch locations again if not
194
specified. (Jelmer Vernooij, #919218)
196
* ``bzr send`` works on treeless branches again.
197
(Jelmer Vernooij, #921591)
199
* ``bzr version`` no longer throws a UnicodeDecodeError if the .bzr.log path
200
contains non-ascii characters. (Martin Packman, #312841)
202
* Support scripts that don't call bzrlib.initialize() but still call run_bzr().
203
(Vincent Ladeuil, #917733)
205
* Test for equality instead of object identity where ROOT_PARENT is concerned.
206
(Wouter van Heyst, #881142)
208
* urllib-based HTTPS client connections now verify the server certificate
209
validity as well as the hostname.
210
(Jelmer Vernooij, Vincent Ladeuil, #651161)
216
* ``config.config_dir`` and related functions now always return paths as
217
unicode. (Martin Packman, #825826)
219
* ``ControlDir`` now has a new method ``set_branch_reference`` which can
220
be used for setting branch references. (Jelmer Vernooij)
222
* ``ControlDir.destroy_branch`` now raises ``NotBranchError`` rather than
223
``NoSuchFile`` if the branch didn't exist. (Jelmer Vernooij, #921693)
228
* A new matcher ``RevisionHistoryMatches`` has been added. (Jelmer Vernooij)
230
* Add new module ``bzrlib.url_policy_open``. (Jelmer Vernooij, #850843)
232
* ``MutableTree`` has two new hooks ``pre_transform`` and
233
``post_transform`` that are called for tree transform operations.
234
(Jelmer Vernooij, #912084)
240
* Be more careful about closing open files for pypy interoperability.
248
This is the fifth (and last) beta of the 2.5 series, leading to a 2.5.0
249
release in February 2012. Beta releases are suitable for everyday use but
250
may cause some incompatibilities with plugins.
252
This release includes many improvements in the smart server, UI polish for
253
the colocated branches, enhancements to the config framework and more
254
internal uses, bug fixes related to unicode and locale support and more.

External Compatibility Breaks
260
*****************************
262
* The '.bzr/branch/email' file is no longer read to determine the users'
263
identity. Instead, the 'email' setting in '.bzr/branch/branch.conf'
264
should be used. (Jelmer Vernooij, #903894)
269
* "bzr mkdir" now includes -p (--parents) option for recursively adding
271
(Jared Hance, Jelmer Vernooij, #253529)
273
* ``config.Option`` can now declare ``override_from_env``, a list of
274
environment variables which, when set, that takes precedence over values
275
defined in configuration files. (Vincent Ladeuil, #907279)
280
* New HPSS call for ``Repository.reconcile``. (Jelmer Vernooij, #894455)
282
* Merge now has two new hooks ``pre_merge`` and ``post_merge``
283
that are called before and after a merge and can make
284
additional modifications to the trees involved.
285
(Jelmer Vernooij, #906877)
287
* Override the value returned by ``sys.getfilesystemencoding()`` for the bzr
288
script to utf-8 when it would otherwise be ascii on a posix system. This
289
will mean bzr works with non-ascii files when no locale or an incorrect
290
locale is set. (Martin Packman, #794353)
292
* ``bzr branches`` now indicates the active colocated branch.
293
(Jelmer Vernooij, #891667)
295
* ``bzr push`` now suggests using :parent if there is a parent location
296
set. (Jelmer Vernooij)
298
* ``bzr send`` now only opens a single connection, rather than two,
299
to the target branch. (Jelmer Vernooij)
304
* Allow configuration option default value to be a python callable at
305
registration. (Vincent Ladeuil, #832064)
307
* ``bzr config`` will now display the section ``[DEFAULT]`` used in
308
``bazaar.conf``. (Vincent Ladeuil, #907268)
310
* Configuration stores can now provides a specific quoting mechanism. This
311
is required to workaround ``configobj`` conflating quoting and list values
312
automatic conversion. (Vincent Ladeuil, #906897)
314
* Create obsolete_packs directory when repacking if it does not
315
exist. (Jonathan Riddell, Jelmer Vernooij, #314314)
317
* Fallback to the slower ``bzr log`` implementation when displaying a range
318
of revisions whose ancestry is not obviously on the same developement
319
line. (Vincent Ladeuil, #904744)
321
* Make lazy imports resilient when resolved concurrently from multiple
322
threads. Now the stand-in object will behave as a proxy for the real object
323
after the initial access, rather than throwing. Assigning the object to
324
multiple names should still be avoided. (Martin von Gagern, #396819)
326
* Not setting ``gpg_signing_key`` or setting it to ``default`` will use the
327
user email (obtained from the ``email`` configuration option or its
328
default value). (Vincent Ladeuil, Jelmer Vernooij, #904550)
330
* Prevent spurious InconsistentDelta error when committing a move of a
331
non-ascii directory with contents. (Rory Yorke, #185211)
333
* Properly ignore '\n' in an option reference since this cannot be part of a
334
config option identifier. (Vincent Ladeuil, #902125)
336
* Make sure that the bzr probers are always registered when
337
bzrlib.workingtree is imported. (Jelmer Vernooij, #905218)
339
* Report mistake trying to move a removed file with a non-ascii name without
340
UnicodeEncodeError being raised. (Martin Packman, #898541)
342
* Safely unquote configuration values in weird edge cases (a section seen as
343
a dictionary which is not a supported use case for the configuration
344
stacks). (Vincent Ladeuil, #908050)
346
* Stop altering ``sys.platform`` on OSX when initialising the locale.
347
(Martin Packman, #570495)
349
* Uncommit no longer removes tags if they are part of the working
350
trees pending merges. (Jelmer Vernooij, #905462)
355
* ``Config.signature_needed``, ``Config.signing_policy``,
356
``Config.gpg_signing_key``, ``Config.gpg_signing_command``,
357
``Config.checking_policy`` and ``Config.post_commit`` are now deprecated.
360
* ``Repository.get_commit_builder`` now takes a ``config_stack``
361
rather than a ``config`` argument. (Jelmer Vernooij)
363
* Scripts using bzrlib should now ensure setlocale is called on posix
364
platforms if they need a non-ascii user encoding. (Martin Packman)
366
* Send formats now accept a new optional argument ``submit_branch``,
367
which can be None or a Branch object for the submit branch location.
370
* ``VersionedFileRepository.add_revision`` no longer takes a ``config``
371
argument. (Jelmer Vernooij)
376
* Add HPSS call for ``Branch.get_checkout_format``. (Jelmer Vernooij, #894459)
378
* Add HPSS call for ``Repository.pack``. (Jelmer Vernooij, #894461)
380
* Add HPSS calls for ``Repository.iter_files_bytes``, speeding up
381
several commands including ``bzr export`` and ``bzr co --lightweight``.
382
(Jelmer Vernooij, #608640)
384
* All bzr control directories, branch formats, repository formats and
385
working tree formats now support feature flags, which are
386
serialized in their respective format files. See
387
``doc/developers/feature-flags.txt`` for details.
390
* ``bzrlib.urlutils`` now includes ``quote`` and ``unquote`` functions,
391
rather than importing them from ``urllib``. This prevents loading
392
of the ``socket``, ``ssl`` and ``urllib`` modules for
393
local bzr operations. (Jelmer Vernooij)
395
* Configuration options can be SI units by using ``int_SI_from_unicode`` as
396
their ``convert_from_unicode`` helper. (Vincent Ladeuil)
398
* Configuration stacks can now use ``StartingPathMatcher`` to select the
399
sections matching a location while respecting the order chosen by the user
400
in the configuration file: from generic sections to specific
401
sections. (Vincent Ladeuil, #832046).
403
* Configuration stores can now save incremental changes by using
404
``save_changes()`` instead of ``save()``. This reduces the number or
405
required input/outputs and allows stores to be shared between
406
stacks. (Vincent Ladeuil)
408
* ControlDir now has a get_branches method that returns a dictionary
409
whose keys are the names of the branches and whose values are the
410
branches themselves. The active branch uses the key None.
411
(Neil Martinsen-Burrell)
413
* Helper ``osutils.path_from_environ`` added for extracting a unicode path
414
from an environment variable. (Martin Packman, #832028)
416
* Helper ``win32utils.get_environ_unicode`` added for avoiding encoding
417
problems with ``os.environ.get`` use. (Martin Packman, #262874)
419
* Lazy imports can now only be absolute. (Jelmer Vernooij)
421
* Merge3Mergers now have an optional ``other_branch`` argument
422
which contains the branch from which the ``other_tree``
423
was obtained, if any. (Jelmer Vernooij)
425
* MutableTree now has a hook ``post_build_tree`` which is called after
426
a new mutable tree has been created. (Jelmer Vernooij, #912765)
428
* New HPSS call ``BzrDir.checkout_metadir``. (Jelmer Vernooij, #894459)
430
* New HPSS call ``VersionedFileRepository.get_inventories``,
431
speeding up various commands including ``bzr export``,
432
``bzr checkout`` and ``bzr cat``. (Jelmer Vernooij, #608640)
434
* The ``ConfigCommandLineStore`` is now supported by ``bzr config`` and is
435
seen as single no-name section of configuration options. (Vincent Ladeuil)
440
* New matcher ``ContainsNoVfsCalls`` which filters a list of HPSS
441
calls for VFS requests. (Jelmer Vernooij)
443
* New ``MemoryStack`` class allows for diskless tests and locally injected
444
configuration stacks. Lower level tests for predefined set of options can
445
be written without setting up configuration files. (Vincent Ladeuil)
453
This is the fourth beta of the 2.5 series, leading to a 2.5.0 release in
454
February 2012. Beta releases are suitable for everyday use but may cause
455
some incompatibilities with plugins.
457
This release includes many improvements in the smart server, UI polish for
458
the colocated branches, optimizations for revision specifiers to avoid
459
history sized operations, enhancements to the config framework, bug fixes
460
related to unicode paths and more.

466
*****************************
473
* Provides a ``po_merge`` plugin to automatically merge ``.po`` files with
474
``msgmerge``. See ``bzr help po_merge`` for details.
475
(Vincent Ladeuil, #884270)
480
* ``bzr branch --stacked`` now only makes a single connection to the remote
481
server rather than three. (Jelmer Vernooij, #444293)
483
* ``bzr export --uncommitted`` will export the uncommitted tree.
484
(Jelmer Vernooij, #555613)
486
* ``bzr rmbranch`` can now remove colocated branches.
487
(Jelmer Vernooij, #831464)
489
* ``bzr status`` no longer shows shelves if files are specified.
492
* ``bzr switch`` now accepts colocated branch names to switch to.
493
(Jelmer Vernooij, #826814)
495
* Plugins can now register additional "location aliases".
498
* Revision specifiers will now only browse as much history as they
499
need to, rather than grabbing the whole history unnecessarily in some
500
cases. (Jelmer Vernooij)
502
* When using ``bzr switch`` to switch to a sibling of the current
503
branch, the relative branch name should no longer be url-encoded.
509
* A new section local option ``basename`` is available to help support some
510
``bzr-pipeline`` workflows and more generally help mapping local paths to
511
remote ones. See ``bzr help configuration`` for more details.
512
(Vincent Ladeuil, #843211)
514
* Add HPSS call for looking up revision numbers from revision ids on
515
remote repositories. (Jelmer Vernooij, #640253)
517
* Add HPSS call for retrieving file contents from remote repositories.
518
Should improve performance for lightweight checkouts and exports of
519
from remote repositories. (Jelmer Vernooij, #368717, #762330, #608640)
521
* Allow lazy compiled patterns from ``bzrlib.lazy_regex`` to be
522
pickled. (Jelmer Vernooij, #893149)
524
* ``bzr info`` no longer shows empty output if only a control
525
directory is present. (Jelmer Vernooij, #159098)
527
* Cope with missing revision ids being specified to
528
``Repository.gather_stats`` HPSS call. (Jelmer Vernooij, #411290)
530
* Fix test failures on windows related to locations.conf handling.
531
(Vincent Ladeuil, #892992)
533
* Fixed parsing of the timestamp given to ``commit --commit-time``. Now
534
prohibits several invalid strings, reads the correct number of seconds,
535
and gives a better error message if the time zone offset is not given.
536
(Matt Giuca, #892657)
538
* Give meaningful file/line references when reporting deprecation warnings
539
for _CompatabilityThunkFeature based test features.
540
(Vincent Ladeuil, #897718)
542
* Make reporting of mistakes involving unversioned files with non-ascii
543
filenames work again without 'Unprintable exception' being shown.
544
(Martin Packman, #898408)
546
* Provide names for lazily registered hooks.
547
(Neil Martinsen-Burrell, #894609)
549
* Raise BadIndexKey exception in btree_index when a key is too large, fixing
550
an infinite recursion issue. (Shannon Weyrick, #720853)
552
* Resolve regression from colocated branch path handling, by ensuring that
553
unreserved characters are unquoted in URLs. (Martin Packman, #842223)
555
* Split segments from URLs for colocated branches without assuming the
556
combined form is valid. (Martin Packman, #842233)
558
* Support looking up revision numbers by revision id in empty branches.
559
(Jelmer Vernooij, #535031)
561
* Support verifying signatures on remote repositories.
562
(Jelmer Vernooij, #889694)
564
* Teach the bzr client how to reconnect if we get ``ConnectionReset``
565
while making an RPC request. This doesn't handle all possible network
566
disconnects, but it should at least handle when the server is asked to
567
shutdown gracefully. (John Arbash Meinel, #819604)
569
* When a remote format is unknown, bzr will now print a single-line error
570
message rather than a backtrace. (Jelmer Vernooij, #687226)
575
* ``BzrDir.open_branch`` and ``BranchFormat.open`` now take an optional
576
``possible_transports`` argument. (Jelmer Vernooij)
578
* New method ``Transport.set_segment_parameter``. (Jelmer Vernooij)
580
* ``Repository.verify_revision`` has been renamed to
581
``Repository.verify_revision_signature``. (Jelmer Vernooij)
583
* ``RevisionSpec.wants_revision_history`` now defaults to ``False`` and
584
is deprecated. The ``revs`` argument of
585
``RevisionInfo.from_revision_id`` is now deprecated. (Jelmer Vernooij)
587
* ``Tree.get_file_by_path`` is now deprecated. Use ``Tree.get_file`` instead.
588
(Jelmer Vernooij, #666897)
590
* Some global options for use with commands have been removed, construct
591
an ``Option`` with the name instead. (Martin Packman)
593
* The unused exception ``HistoryMissing`` has been removed.
599
* Add HPSS call for ``Repository.pack``. (Jelmer Vernooij, #894461)
601
* ``bzr config`` uses the new configuration implementation.
604
* Custom HPSS error handlers can now be installed in the smart server client
605
using the ``error_translators`` and ``no_context_error_translators``
606
registries. (Jelmer Vernooij)
608
* New HPSS calls ``Repository.has_signature_for_revision_id``,
609
``Repository.make_working_trees``, ``BzrDir.destroy_repository``,
610
``BzrDir.has_workingtree``, ``Repository.get_physical_lock_status``,
611
``Branch.get_physical_lock_status``,
612
``Branch.put_config_file``, ``Branch.break_lock``,
613
``BzrDir.destroy_branch``, ``Repository.break_lock``,
614
``VersionedFileRepository.get_serializer_format``,
615
``Repository.all_revision_ids``, ``Repository.start_write_group``,
616
``Repository.commit_write_group``, ``Repository.abort_write_group``
617
``Repository.check_write_group``, ``Repository.iter_revisions``,
618
``Repository.add_signature_revision_text`` and
619
``Repository.get_revision_signature_text``.
622
* ``RemoteBranch.get_config_stack`` and ``RemoteBzrDir.get_config_stack``
623
will now use HPSS calls where possible. (Jelmer Vernooij)
625
* The registry of merge types has been moved to ``merge`` from ``option`` but
626
``merge.get_merge_type_registry`` remains as an accessor. (Martin Packman)
631
* Avoid failures in test_transform when OS error messages are localised.
632
(Martin Packman, #891582)
634
* Tests are now subject to a time limit: by default 300s, and 120s when
635
run from 'make check', controlled by the `selftest.timeout`
636
configuration option. This is currently not supported on Windows.
644
This is the third beta of the 2.5 series, leading to a 2.5.0 release in
645
February 2012. Beta releases are suitable for everyday use but may cause
646
some incompatibilities with plugins.
648
This release includes log options for ``push`` and ``pull``, more UI polish
649

650
dialogs, enhancements to the config framework and more.

656
*****************************
663
* The ``log_format`` configuration can be used with ``-Olog_format=line`` to
664
change the format ``push`` and ``pull`` use to display the
665
revisions. I.e.: ``bzr pull -v -Olog_format=short`` will use the ``short``
666
format instead of the default ``long`` one. (Vincent Ladeuil, #861472)
668
* The new config scheme allows an alternative syntax for the 'appenpath'
669
policy relying on option expansion and defining a new 'relpath' option
670
local to a section. Instead of using '<option>:policy=appendpath', the
671
option value can de defined as 'option=xxxx/{relpath}'.
672
(Vincent Ladeuil, #832013)
677
* ``bzr info -v`` now shows the number of colocated branches
678
for control directories that support them.
679
(Jelmer Vernooij, #863285)
681
* ``bzr version-info`` now takes a ``--revision`` argument.
682
(Jelmer Vernooij, #238705)
684
* ``bzr revno`` now takes a ``--revision`` argument.
685
(Jelmer Vernooij, #870649)
687
* ``bzr serve`` now can serve from URLs rather than just from the
688
file system. I.e.: ``bzr serve -d lp:bzr`` or
689
``bzr serve -d file:///data/bzr`` (Jelmer Vernooij)
691
* all input prompts are now char-based when possible, and can be forced to
692
line-based mode by setting the ``BZR_TEXTUI_INPUT`` environment variable
693
to 'line-based'. This replace the previous shelf UI only patch using
694
``INSIDE_EMACS``. (Benoît Pierre)
699
* ``bzr info`` now shows the master branch location too for
700
treeless local branches. (Jelmer Vernooij, #258355)
702
* ``bzr mkdir --quiet`` now does not print a line for every created
703
directory. (Martin von Gagern, #869915)
705
* ``bzr mv`` does not crash when attempting to move the root of a
706
branch. (Jonathan Riddell, #809728)
708
* ``bzr shelve`` now use ``UIFactory.choose`` for input handling, making
709
it usable when creating a custom ``UIFactory`` implementation. (Benoît
712
* ``bzr clean-tree`` now use ``UIFactory.get_boolean`` for confirmation
713
prompt, making it usable when using a custom ``UIFactory``
714
implementation. (Benoît Pierre)
716
* If sending a crash through Apport fails report the Apport failure to
717
bzr.log rather than stderr. (Jonathan Riddell, #766735)
719
* ``bzr upgrade`` no longer treats 'already up-to-date' exceptions as
720
errors. (Benoît Pierre, #716560).
722
* ``bzr version-info`` no longer populates the clean state for custom
723
templates unless {clean} is explicitly asked for.
724
(Lawrence Mitchell, #882541)
726
* Fix finding the CPU count when using Python >= 2.6 on BSD-based systems.
727
(Jelmer Vernooij, #887151)
729
* ``WorkingTree.clone()`` now supports its ``revision_id`` being set
730
to the null revision. (Jelmer Vernooij, #876423)
732
* ``WorkingTree.pull`` can now pull ``NULL_REVISION``.
733
(Jelmer Vernooij, #887556)
738
* ``Branch.revision_history`` is now deprecated. (Jelmer Vernooij, #799519)
740
* Methods ``add`` and ``items`` of ``LRUCache`` and ``LRUSizeCache`` are
741
deprecated. Use normal dict-style access instead. (Martin Packman)
743
* New flag ``RepositoryFormat.supports_unreferenced_revisions`` which
744
indicates whether revisions can be present in a repository without
745
being referenced from e.g. a branch history at the same time.
748
* ``UIFactory.choose`` has been added: prompt the user for a list of
749
choices. (Benoît Pierre)
754
* ``ControlDirFormat`` now has a new method ``supports_transport``
755
which format implementations can use whether or not they can access
756
a control dir over a particular transport. (Jelmer Vernooij)
758
* ``BranchBuilder.build_commit`` now take ``parent_ids`` and
759
``allow_leftmost_as_ghost`` arguments. (Jelmer Vernooij)
764
* Ensure TestCase instances are deallocated immediately after running where
765
possible. This greatly reduces the peak resource needs of a full test suite
766
run. The new ``-Euncollected_cases`` selftest flag will add failures if any
767
case which persists pasts its expected lifetime. (Martin Packman, #613247)
769
* Report exceptions from child processes during fork instead of swallowing the
770
error and reporting that everything went okay. (Martin Packman, #804130)
776
This is the second beta of the 2.5 series, leading to a 2.5.0 release in
777
February 2012. Beta releases are suitable for everyday use but may cause some
778
incompatibilities with plugins.
780
This release includes more filtering options for ``bzr log``, idle
781
connections handling for ``bzr serve``, a ``development-colo`` experimental
782
format to flesh out the colocated branches UI, better support for foreign
783
formats, enhancements to the config framework and more.
785
This release includes all bug fixed in previous series known at the time of
790
External Compatibility Breaks
791
*****************************
798
* A new ``-O`` standard option (common to all commands) have been added. It
799
provides a value for a config option in the ``-Oname=value`` form that
800
takes precedence over all definitions found in config files. It can be
801
used multiple times to override different options.
802
(Vincent Ladeuil, #491196)
804
* ``bzr log`` now has an option called ``--omit-merges`` to omit
805
those commits that merged branches, i.e. those having more than one
807
In order to avoid confusion, the previous command line option
808
``--include-merges`` has been renamed to ``--include-merged``.
809
The old name of the command line option will still be accepted.
810
The name change also affects ``bzr missing``.
813
* ``bzr serve`` will now disconnect clients if they have not issued an RPC
814
request after 5minutes. On POSIX platforms, this will also happen for
815
``bzr serve --inet``. This can be overridden with the configuration
816
variable ``serve.client_timeout`` or in the command line parameter
817
``bzr serve --client-timeout=X``. Further, it is possible to request
818
``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will
819
finish the current request, and then close the connection.
820
(John Arbash Meinel, #824797, #795025)
822
* The new experimental format ``development-colo`` supports colocated
823
branches. This format will eventually be merged back into the ``2a``
824
format when it has stabilized and there is adequate UI support for
826
(Jelmer Vernooij, #831481)
831
* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for
832
every revision in the range; it's now much faster. (Vincent Ladeuil, #857335)
834
* ``bzr info -v`` can now be run against branches that don't support
835
``last_revision_info``, in which case the branch information will simply
836
not be displayed. (Jelmer Vernooij)
841
* ``bzr shelve`` can now be used in emacs shells as the input handling is
842
turned into a line-based one when ``INSIDE_EMACS`` is set (which is the
843
case for all recent emacs versions). (Vincent Ladeuil, #856261)
845
* ``bzr tags`` can now be used against remote repositories that do
846
not provide access to the revision graph. (Jelmer Vernooij, #858942)
848
* ``bzr update PATH`` will stop if you seem to be asking it to update
849
anything less than a whole tree, because that's not supported by ``bzr``'s
850
concept that the whole tree has a single basis revision. Previously, it
851
would go ahead and update the whole tree, which was surprising.
852
(Martin Pool, #557886)
854
* Don't crash if ``bzrlib.initialize()`` has not been called while accessing
855
configs. (Vincent Ladeuil, #863401)
857
* Redirects between http and https no longer discard path information
858
in some cases. (Jelmer Vernooij, #853765)
860
* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer
861
reports all tags as changed. (Jelmer Vernooij, #845396)
863
* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is
864
specified that is unknown. (Jelmer Vernooij, #847435)
870
* ``Branch.get_revision_delta`` has been deprecated. Use
871
``Repository.get_revision_delta`` instead. (Jelmer Vernooij, #859712)
873
* Plugins that implement custom protocols for ``bzr serve`` should now
874
also take an argument ``timeout``. This is used by the the bzr protocol
875
to close a connection if a client has been idle for more than X seconds.
876
(Default 5minutes). (John Arbash Meinel)
878
* ``Repository.fileids_altered_by_revision_ids`` has been moved to
879
``VersionedFileRepository`` and is no longer part of the standard
880
``Repository`` interface. (Jelmer Vernooij)
882
* The argument ``include_merges`` to ``missing.find_unmerged`` has
883
been renamed to ``include_merged``. The old name is still supported
884
for now but will cause a deprecation warning. (Martin von Gagern)
886
* The new method ``ControlDirFormat.is_initializable()`` returns a boolean
887
indicating whether or not it is possible to use any of the
888
initialization methods of that format to create a new control dir.
894
* ``Branch`` objects can now use a config stack with the newly introduced
895
``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can
896
be used for the same branch but it's recommended to stick to one for a
902
* Test scripts can now use ``bzr shelve`` and provide their input as
903
complete lines. (Vincent Ladeuil, #856261)
905
* Really corrupt the pack file without depending on a special length or value.
906
(Vincent Ladeuil, #807032)
914
This is the first beta of the 2.5 series, leading up to a 2.5.0
915
release in February 2012.
917
This release includes better support for gpg signing, better support for
918
i18n (mostly command help and error messages), more options to filter ``bzr
919
log`` output, more support for colocated branches ("location,branch=XXX"
920
syntax), better feedback on updated tags for various commands, faster
921
branching into an empty repository, enhancements to the config framework and
924
Beta releases are suitable for everyday use but may cause some
925
incompatibilities with plugins. Some plugins may need small updates to work
928
External Compatibility Breaks
929
*****************************
936
* A ``from_unicode`` parameter can be specified when registering a config
937
option. This implements boolean, integer and list config options when the
938
provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``
939
are used for this parameter. (Vincent Ladeuil)
941
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
942
checks to see if the most recent published source package version for
943
that project is present in the branch tags. This should help developers
944
trust whether the packaging branch is up-to-date and can be used for new
945
changes. The level of verbosity is controlled by the config item
946
``launchpad.packaging_verbosity``. It can be set to one of
953
only display if the branch is out-of-date
956
also display single-line up-to-date and missing,
960
(default) display multi-line content for all states
963
(John Arbash Meinel, #609187, #812928)
965
* Add a config option gpg_signing_key for setting which GPG key should
966
be used to sign commits. Also default to using the gpg user identity
967
which matches user_email() as set by whoami.
968
(Jonathan Riddell, #68501)
970
* An ``invalid`` parameter can be specified when registering a config option
971
to decide what should be done when invalid values are
972
encountered. 'warning' and 'error' will respectively emit a warning and
973
ignore the value or errors out. (Vincent Ladeuil)
975
* bzr add now skips large files in recursive mode. The default "large"
976
size is 20MB, and is configurable via the add.maximum_file_size
977
option. A value of 0 disables skipping. Named items passed to add are
978
never skipped. (Shannon Weyrick, #54624)
980
* ``bzr help configuration/<option>`` display the help for ``option`` for
981
all registered configuration options. (Vincent Ladeuil, #747050)
983
* ``bzr log -m`` now matches message, author, committer and bugs instead
984
of just matching the message. ``--message`` keeps its original meaning,
985
while ``--match-message, --match-author, --match-committer`` and
986
``--match-bugs`` match each of those fields. (Jacek Sieka)
988
* ``config.Option`` can now declare ``default_from_env``, a list of
989
environment variables to get a default value from. (Vincent Ladeuil)
991
* ``config.NameMatcher`` can be used to implement config stores and stacks
992
that need to provide specific option values for arbitrary unique IDs (svn
993
repository UUIDs, etc). (Vincent Ladeuil, #843638)
995
* New builtin ``bzr branches`` command, which lists all colocated branches
996
in a directory. (Jelmer Vernooij, #826820)
998
* Relative local paths can now be specified in URL syntax by using the
999
"file:" prefix. (Jelmer Vernooij)
1001
* Report commits signed with expired keys in ``verify-signatures``.
1002
(Jonathan Riddell, #804254)
1004
* Translations are now enabled for command help, errors and globally
1005
for any message using ``gettext`` given on output. (Jonathan Riddell,
1006
INADA Naoki, #83941)
1011
* ``bzr add`` will now warn about nested subtrees that are skipped.
1012
(Jelmer Vernooij, #187342)
1014
* ``bzr commit -m ''`` can now be used to force an empty commit message.
1015
Entering an empty commit message in the message editor still triggers
1016
an error. (Jelmer Vernooij)
1018
* ``bzr pull`` will now mention how many tags it has updated.
1019
(Jelmer Vernooij, #164450)
1021
* ``bzr tag`` no longer errors if a tag already exists but refers to the
1022
same revision, and will mention when a tag has been updated
1023
rather than created. (Jelmer Vernooij, #381203)
1025
* ``bzr uncommit`` will now remove tags that refer to removed revisions.
1026
The ``--keep-tags`` option can be used to prevent this behaviour.
1027
(Jelmer Vernooij, #605814)
1029
* Do not run i18n initialisation twice. (Jonathan Riddell)
1031
* Install translation .mo files. (Jonathan Riddell)
1033
* Locations printed by ``bzr upgrade`` are now formatted before display.
1036
* ``Repository.get_parent_map`` now estimates the size of the returned
1037
content more accurately. This means that we get closer to the desired
1038
64kB/request. For repositories converted from svn, this can be an
1039
improvement of approx 5:1 in round trips to discover the whole history.
1040
(John Arbash Meinel)
1042
* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
1043
if no bug tracker was specified on the command line.
1044
(Jelmer Vernooij, #334860)
1046
* Use ``gettext.NullTranslations`` in i18n to allow use of i18n even when
1047
translations are not turned on. (Jonathan Riddell)
1052
* ``bzr commit`` now correctly reports missing files as "removed", not
1053
"modified". (Jelmer Vernooij, #553955)
1055
* ``bzr reconfigure`` will now allow multiple non-conflicting requests
1056
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
1057
(Martin von Gagern, #842993)
1059
* A call to CHKInventory's filter-method will not result in a
1060
DuplicateFileId error, if you move a subfolder and change a file in
1062
(Bastian Bowe, #809901)
1064
* Branching from a stacked branch no longer does a ``get_parent_map``
1065
request for each revisions that is in the stacked-on repository while
1066
determining what revisions need to be fetched. This mostly impacts
1067
branching initialy into an empty shared repository when the source is
1068
not the development focus. (John Arbash Meinel, #388269)
1070
* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
1071
errors. (Vincent Ladeuil, #822571)
1073
* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
1074
raised whenever a transport at the drive root was opened on windows.
1075
(Martin [gz], #841322)
1077
* Fixed loading of external merge tools from config to properly decode
1078
command-lines which contain embedded quotes. (Gordon Tyler, #828803)
1080
* Rather than an error being raised, a warning is now printed when the
1081
current user does not have permission to read a configuration file.
1082
(Jelmer Vernooij, #837324)
1084
* The pull command will now always use separate connections for the
1085
case where the destination is a heavyweight checkout of some remote
1086
branch on the same host as the source branch.
1087
(Martin von Gagern, #483661)
1089
* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
1090
operations that use it, like merge, can now create trees without a root.
1093
* Fixed problem with getting errors about failing to open /dev/tty when using
1094
Bazaar Explorer to sign commits. (Mark Grandi, #847388)
1099
* Release instructions refreshed. (Vincent Ladeuil)
1104
* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
1105
argument. (Jelmer Vernooij)
1107
* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
1108
which indicates if the format should be for a lightweight or a
1109
heavyweight checkout. (Jelmer Vernooij)
1111
* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
1114
* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
1117
* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
1118
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
1121
* New method ``InterTree.file_content_matches`` which checks that
1122
two files in different trees have the same contents.
1125
* New method ``Tree.get_file_verifier`` which allows tree implementations
1126
to return non-sha1 checksums to verify files.
1127
(Jelmer Vernooij, #720831)
1129
* New methods ``get_transport_from_path`` and ``get_transport_from_url``
1130
have been added that only support opening from a path or a URL,
1131
unlike ``get_transport``. (Jelmer Vernooij)
1133
* New registry ``OptionRegistry`` specialized for configuration options.
1136
* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
1139
* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
1140
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
1141
2.10 and 2.2.0. (Vincent Ladeuil)
1143
* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.
1145
* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
1146
``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
1147
remove ``log.show_one_log`` which was never properly deprecated but wasn't
1148
used and is easy to inline if needed. (Vincent Ladeuil)
1150
* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
1151
deprecated in 2.1.0. (Vincent Ladeuil)
1153
* Remove ``TransportListRegistry.set_default_transport``, as the concept of
1154
a default transport is currently unused. (Jelmer Vernooij)
1156
* Remove ``UIFactory.warn_cross_format_fetch`` and
1157
``UIFactory.warn_experimental_format_fetch`` in favor of
1158
``UIFactory.show_user_warning``. (Jelmer Vernooij)
1160
* ``Tags`` containers can now declare whether they support versioned
1161
tags and whether tags can refer to ghost tags.
1164
* ``Tags.merge_to`` now returns a dictionary with the updated tags
1165
and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)
1167
* There is a new class `ContentFilterTree` that provides a facade for
1168
content filtering. The `filtered` parameter to `export` is deprecated
1169
in favor of passing a filtered tree, and the specific exporter plugins
1170
no longer support it.
1173
* ``Transport`` now has a ``_parsed_url`` attribute instead of
1174
separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
1175
and ``_path`` attributes. Proxies are provided for the moment but
1176
may be removed in the future. (Jelmer Vernooij)
1181
* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
1182
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
1183
is attempted. (Jelmer Vernooij)
1185
* New method ``ControlDir._get_selected_branch`` which returns the
1186
colocated branch selected using path segment parameters.
1187
(Jelmer Vernooij, #380871)
1192
* Blackbox tests (including test scripts) can be debugged interactively (see
1193
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)
1195
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
1196
cleanly and reliably allows tests using `BranchBuilder` to construct
1197
branches that e.g. rename files out of a directory and unversion that
1198
directory in the same revision. Previously some changes were impossible
1199
due to the order that `build_snapshot` performs its actions.
1202
* Don't require ``os.fdatasync`` to be defined on all supported OSes
1203
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)
1205
* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
1207
* ``LockDir`` can now be run when the local hostname is ``localhost``.
1208
(Jelmer Vernooij, #825994)
1210
* ``ModuleAvailableFeature`` won't try to import already imported modules,
1211
allowing it to be used for modules with side-effects.
1212
(Vincent Ladeuil, #712474)
1214
* Output time stamps while running ``make check`` to get better timings from
1215
pqm. (Vincent Ladeuil, #837926)
1217
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
1218
just compares the bytes in the dirstate file to its pristine state,
1219
rather than opening the WorkingTree and calling ``last_revision()``.
1220
This reduces the overall test suite time by about 10% on my laptop.
1223
* Update `TestCase.knownFailure` to the testtools way of handling expected
1224
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
