:2.2b3: NOT RELEASED YET
16
* An API break has been made to the lock_write method of ``Branch`` and
17
``Repository`` objects; they now return ``branch.BranchWriteLockResult``
18
and ``repository.RepositoryWriteLockResult`` objects. This makes
19
changing the API in future easier and permits some cleaner calling code.
25
* ``bzr commit`` accepts ``-p`` (for "patch") as a shorter name for
27
(Parth Malwankar, #571467)
29
* ``bzr ignore`` now supports a ``--default-rules`` option that displays
30
the default ignore rules used by bzr. The flag ``--old-default-rules``
31
is no longer supported by ``ignore``.
32
(Parth Malwankar, #538703)
34
* ``bzr pack`` now supports a ``--clean-obsolete-packs`` option that
35
can save disk space by deleting obsolete pack files created during the
37
(Parth Malwankar, #304320)
42
* ``.bazaar``, ``.bazaar/bazaar.conf`` and ``.bzr.log`` inherit user and
43
group ownership from the containing directory. This allow bzr to work
45
(Martin <gzlist@googlemail.com>, Parth Malwankar, #376388)
47
* ``bzr log --exclude-common-ancestry -r X..Y`` displays the revisions that
48
are part of Y ancestry but not part of X ancestry (aka the graph
50
(Vincent Ladeuil, #320119)
52
* ``bzr selftest --parallel=fork`` wait for its children avoiding zombies.
53
(Vincent Ladeuil, #566670)
55
* ``bzr selftest`` should not use ui.note() since it's not unicode safe.
56
(Vincent Ladeuil, #563997)
58
* Don't mention --no-strict when we just issue the warning about unclean trees.
59
(Vincent Ladeuil, #401599)
61
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
63
(Andrew Bennetts, #528041)
65
* Reduce peak memory by one copy of compressed text.
66
(John Arbash Meinel, #566940)
68
* Show the filenames when a file rename fails so that the error will be
70
(Martin Pool, #491763)
75
* ``append_revisions_only`` will now be interpreted as a boolean and a
76
warning emitted if illegal values are used. Note that for projects
77
that needs to maintain compatibility with previsous bzr versions,
78
only 'True' and 'False' strings must be used (previous versions of
79
bzr will interpret all strings differing from 'True'
80
(case-sensitive) as false.
81
(Brian de Alwis, Vincent Ladeuil)
83
* ``Config.get_user_option_as_bool`` will now warn if a value cannot
84
be interpreted as a boolean.
93
* Added ``bzrlib.merge.PerFileMerger``, a more convenient way to write
94
some kinds of ``merge_file_content`` hook functions.
97
* `BzrDir`, `Branch`, `Repository` and `WorkingTree` now all support `user_url`,
98
`user_transport`, `control_url` and `control_transport` members pointing
99
respectively to the directory containing the ``.bzr`` control directory,
100
and to the directory within ``.bzr`` used for the particular component.
101
All of them inherit from `ControlComponent` which provides default
105
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
106
expected to return an object which can be used to unlock them. This reduces
107
duplicate code when using cleanups. The previous 'tokens's returned by
108
``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
109
on the result of the lock_write. ``repository.RepositoryWriteLockResult``
110
and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
115
* ``log._get_info_for_log_files`` now takes an add_cleanup callable.
118
* ``_remember_remote_is_before`` no longer raises AssertionError when
119
suboptimal network behaviour is noticed; instead it just mutters to the
120
log file (and warns the user if they have set the ``hpss`` debug flag).
121
This was causing unnecessary aborts for performance bugs that are minor
123
(Andrew Bennetts, #528041)
125
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
126
files loaded from disk. To ensure docstrings needed for help are never
127
stripped, the prefix ``__doc__ =`` should now be used.
128
(Martin <gzlist@googlemail.com>)
133
* Added ``bzrlib.tests.matchers`` as a place to put matchers, along with
134
our first in-tree matcher. See the module docstring for details.
137
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
138
(Gordon Tyler, #551332)
140
* Workaround ``Crypto.Random`` check leading to spurious test
141
failures on Lucid, FreeBSD and gentoo.
142
(Vincent Ladeuil, #528436)
149
This is a somewhat early second beta of the 2.2 series, to fix a python2.4
150
incompatibility in the 2.2b1 release. It also includes a swag of
151
performance, usability and correctness improvements: test feedback on all
152
of these would be welcome.
158
* ``bzr diff`` now supports a --format option, which can be used to
159
select alternative diff formats. (Jelmer Vernooij, #555994)
164
* ``bzr dpush``, ``bzr push`` and ``bzr send`` will now issue a warning
165
instead of failing when dirty trees are involved. The corresponding
166
``dpush_strict``, ``push_strict`` and ``send_strict`` should be set to
167
True explicitly to get the previous behaviour.
168
(Vincent Ladeuil, #519319)
170
* ``bzr export`` to tar file does not fail if any parent directory
171
contains unicode characters. This works around upstream Python bug
172
http://bugs.python.org/issue8396 .
173
(Parth Malwankar, #413406)
175
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
176
(Aaron Bentley, #559436)
178
* ``bzr update`` when a pending merge in the working tree has been merged
179
into the master branch will no longer claim that old commits have become
180
pending merges. (Robert Collins, #562079)
182
* ``bzrlib.mutabletree.MutableTree.commit`` will now support a passed in
183
config as in previous versions of bzrlib. (Robert Collins)
185
* Fix glitch in the warning about unclean trees display.
186
(Vincent Ladeuil, #562665)
188
* Fixed Python2.4 incompatibilities in the bzr2.2b1 source tarball.
191
* Help messages generated by ``RegistryOption.from_kwargs`` list the
192
switches in alphabetical order, rather than in an undefined order.
193
(Martin von Gagern, #559409)
195
* Make sure the ``ExecutablePath`` and ``InterpreterPath`` are set in
196
Apport crash reports, to avoid "This problem report applies to a program
197
which is not installed any more" error.
198
(Martin Pool, James Westby, #528114)
200
* Reset ``siginterrupt`` flag to False every time we handle a signal
201
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
202
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
203
errors after two window resizes.
206
* When invoked with a range revision, ``bzr log`` doesn't show revisions
207
that are not part of the Y revisions ancestry anymore when invoked with
209
(Vincent Ladeuil, #474807)
211
* Properly handle ``param_name`` attribute for ``ListOption``.
212
(Martin von Gagern, 387117)
217
* ``bzr commit`` will prompt before using a commit message that was
218
generated by a template and not edited by the user.
219
(Robert Collins, #530265)
221
* ``bzr diff`` read-locks the trees and branches only once, saving about
222
10-20ms on ``bzr diff`` in a bzr.dev tree.
225
* ``bzr missing`` read-locks the branches only once.
228
* ``bzr pull`` locks the branches and tree only once.
231
* Index lookups in pack repositories search recently hit pack files first.
232
In repositories with many pack files this can greatly reduce the
233
number of files accessed, the number of bytes read, and the number of
234
read calls. An incremental pull via plain HTTP takes half the time and
235
bytes for a moderately large repository. (Andrew Bennetts)
237
* Index lookups only re-order the indexes when the hit files aren't
238
already first. Reduces the cost of reordering
239
(John Arbash Meinel, #562429)
241
* Less code is loaded at startup. (Cold-cache start time is about 10-20%
243
(Martin Pool, #553017)
248
* ``bzrlib.diff.get_trees_and_branches_to_diff`` is deprecated. Use
249
``get_trees_and_branches_to_diff_locked`` instead.
255
* ``bzrlib.commands.Command.run_direct`` is no longer needed - the pre
256
2.1 method of calling run() to perform testing or direct use via the API
257
is now possible again. As part of this, the _operation attribute on
258
Command is now transient and only exists for the duration of ``run()``.
269
* BTreeGraphIndex can now take an offset to indicate that the data starts
270
somewhere other than then beginning of the file. (John Arbash Meinel)
272
* Deleted very old hidden commands ``versionedfile-list``,
273
``weave-plan-merge``, ``weave-merge-text``.
276
* ``Repository.get_inventory_sha1()`` and ``Repository.get_revision_xml()``
277
have been removed. (Jelmer Vernooij)
279
* ``Repository.get_revision_inventory()`` has been removed in favor of
280
``Repository.get_inventory()``. (Jelmer Vernooij)
282
* All test servers have been moved out of the bzrlib.transport hierarchy to
283
bzrlib.tests.test_server *except* for MemoryServer, ChrootServer and
284
PathFilteringServer. ``bzrlib`` users may encounter test failures that can
285
be fixed by updating the related imports from ``bzrlib.transport.xxx`` to
286
``bzrlib.tests.test_server``.
289
* ``BranchReferenceFormat.initialize()`` now takes an optional name argument
290
as its second parameter, for consistency with the initialize() method of
291
other formats. (Jelmer Vernooij)
296
* Added ``bzr remove-branch`` command that can remove a local or remote
297
branch. (Jelmer Vernooij, #276295)
299
* ``bzr export`` now takes an optional argument ``--per-file-timestamps``
300
to set file mtimes to the last timestamp of the last revision in which
301
they were changed rather than the current time. (Jelmer Vernooij)
303
* If the Apport crash-reporting tool is available, bzr crashes are now
304
stored into the ``/var/crash`` apport spool directory, and the user is
305
invited to report them to the developers from there, either
306
automatically or by running ``apport-bug``. No information is sent
307
without specific permission from the user. (Martin Pool, #515052)
309
* Parsing of command lines, for example in ``diff --using``, no longer
310
treats backslash as an escape character on Windows. (Gordon Tyler,
313
* Plugins can be disabled by defining ``BZR_DISABLE_PLUGINS`` as
314
a list of plugin names separated by ':' (';' on windows).
315
(Vincent Ladeuil, #411413)
317
* Plugins can be loaded from arbitrary locations by defining
318
``BZR_PLUGINS_AT`` as a list of name@path separated by ':' (';' on
319
windows). This takes precedence over ``BZR_PLUGIN_PATH`` for the
320
specified plugins. This is targeted at plugin developers for punctual
321
needs and *not* intended to replace ``BZR_PLUGIN_PATH``.
322
(Vincent Ladeuil, #82693)
324
* Tag names can now be determined automatically by ``automatic_tag_name``
325
hooks on ``Branch`` if they are not specified on the command line.
328
* Tree-shape conflicts can be resolved by providing ``--take-this`` and
329
``--take-other`` to the ``bzr resolve`` command. Just marking the conflict
330
as resolved is still accessible via the ``--done`` default action.
333
* Merges can be proposed on Launchpad with the new lp-propose-merge command.
334
(Aaron Bentley, Jonathan Lange)
339
* Added docstring for ``Tree.iter_changes``
340
(John Arbash Meinel, #304182)
342
* Allow additional arguments to
343
``RemoteRepository.add_inventory_by_delta()``. (Jelmer Vernooij, #532631)
345
* Allow exporting a single file using ``bzr export``.
346
(Michal Junák, #511987)
348
* Allow syscalls to automatically restart when ``TextUIFactory``'s
349
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
350
IO, which are often poorly handled by Python's libraries and parts of
351
bzrlib. (Andrew Bennetts, #496813)
353
* Avoid infinite recursion when probing for apport.
354
(Vincent Ladeuil, #516934)
356
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
357
(Martin Pool, #331095)
359
* Avoid truncating svn URLs.
360
(Martin Pool, Martin von Gagern, #545185)
362
* ``bzr add`` will not add conflict related files unless explicitly required.
363
(Vincent Ladeuil, #322767, #414589)
365
* ``bzr dump-btree`` now works on ``*.cix`` and ``*.six`` files. Those
366
indices do not have reference lists, so ``dump-btree`` will simply show
367
``None`` instead. (Andrew Bennetts, #488607)
369
* ``bzr help`` will no longer trigger the get_missing_command hook when
370
doing a topic lookup. This avoids prompting (like 'no command plugins/loom,
371
did you mean log?') when getting help. In future we may trigger the hook
372
deliberately when no help topics match from any help index.
373
(Robert Collins, #396261)
375
* ``bzr log -n0 -r..A.B.C`` should not crash but just consider the None
376
revspec as representing the first revision of the branch.
377
(Vincent Ladeuil, #519862)
379
* ``bzr remove-tree`` can now remove multiple working trees.
380
(Jared Hance, Andrew Bennetts, #253137)
382
* ``bzr resolve --take-this`` and ``--take-other`` now correctly renames
383
the kept file on content conflicts where one side deleted the file.
384
(Vincent Ladeuil, #529968)
386
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
387
permissions as ``.bzr`` directory on a POSIX OS.
388
(Parth Malwankar, #262450)
390
* ``bzr upgrade`` now names backup directory as ``backup.bzr.~N~`` instead
391
of ``backup.bzr``. This directory is ignored by bzr commands such as
393
(Parth Malwankar, #335033, #300001)
395
* Cope with non-utf8 characters inside ``.bzrignore``.
396
(Jason Spashett, #183504)
398
* Correctly interpret "451 Rename/move failure: Directory not empty" from
399
ftp servers while trying to take a lock.
400
(Martin Pool, #528722)
402
* DirStateRevisionTree.kind() was returning wrong result when 'kind'
403
changes occured between the workingtree and one of its parents.
404
(Vincent Ladeuil, #535547)
406
* Fix ``log`` to better check ancestors even if merged revisions are involved.
407
(Vincent Ladeuil, #476293)
409
* Loading a plugin from a given path with ``BZR_PLUGINS_AT`` doesn't depend
410
on os.lisdir() order and is now reliable.
411
(Vincent Ladeuil, #552922).
413
* Many IO operations that returned ``EINTR`` were retried even if it
414
wasn't safe to do so via careless use of ``until_no_eintr``. Bazaar now
415
only retries operations that are safe to retry, and in some cases has
416
switched to operations that can be retried (e.g. ``sock.send`` rather than
418
(Andrew Bennetts, Martin <gzlist@googlemail.com>, #496813)
420
* Path conflicts now support --take-this and --take-other even when a
421
deletion is involved.
422
(Vincent Ladeuil, #531967)
424
* Network transfer amounts and rates are now displayed in SI units according
425
to the Ubuntu Units Policy <https://wiki.ubuntu.com/UnitsPolicy>.
426
(Gordon Tyler, #514399)
428
* Support kind markers for socket and fifo filesystem objects. This
429
prevents ``bzr status --short`` from crashing when those files are
430
present. (John Arbash Meinel, #303275)
432
* ``bzr mkdir DIR`` will not create DIR unless DIR's parent is a versioned
433
directory. (Parth Malwankar, #138600)
435
* SSH child processes will now ignore SIGQUIT on nix systems so breaking into
436
the debugger won't kill the session.
437
(Martin <gzlist@googlemail.com>, #162502)
439
* Tolerate patches with leading noise in ``bzr-handle-patch``.
440
(Toshio Kuratomi, Martin Pool, #502076)
442
* ``update -r`` now supports updating to revisions that are not on
443
mainline (i.e. it supports dotted revisions).
444
(Parth Malwankar, #517800)
446
* Use first apparent author not committer in GNU Changelog format.
447
(Martin von Gagern, #513322)
452
* ``bzrlib.merge_directive._BaseMergeDirective`` has been renamed to
453
``bzrlib.merge_directive.BaseMergeDirective`` and is now public.
456
* ``BranchFormat.initialize`` now takes an optional ``name`` of the colocated
457
branch to create. (Jelmer Vernooij)
459
* ``BzrDir.get_branch_transport`` now takes an optional ``name`` of the
460
colocated branch to open. (Jelmer Vernooij)
462
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
463
can set a signal handler and call ``signal.siginterrupt(signum,
464
False)`` for it, if the platform and Python version supports it.
465
(Andrew Bennetts, #496813)
467
* New ``bzrlib.initialize`` is recommended for programs using bzrlib to
468
run when starting up; it sets up several things that previously needed
469
to be done separately.
470
(Martin Pool, #507710)
472
* Exporters now support a ``per_file_timestamps`` argument to write out the
473
timestamp of the commit in which a file revision was introduced.
476
* New method ``BzrDir.list_branches()`` that returns a sequence of branches
477
present in a control directory. (Jelmer Vernooij)
479
* New method ``Repository.get_known_graph_ancestry()``.
480
(Jelmer Vernooij, #495502)
482
* New transport methods ``readlink``, ``symlink`` and ``hardlink``.
485
* Remove unused ``CommandFailed`` exception.
491
* ``bzrlib.branchbuilder.BranchBuilder.build_snapshot`` now accepts a
492
``message_callback`` in the same way that commit does. (Robert Collins)
494
* ``bzrlib.builtins.Commit.run`` raises ``bzrlib.errors.BoundBranchOutOfDate``
495
rather than ``bzrlib.errors.BzrCommandError`` when the bound branch is out
496
of date. (Gary van der Merwe)
498
* ``bzrlib.commands.run_bzr`` is more extensible: callers can supply the
499
functions to load or disable plugins if they wish to use a different
500
plugin mechanism; the --help, --version and no-command name code paths
501
now use the generic pluggable command lookup infrastructure.
504
* ``bzrlib.errors.BoundBranchOutOfDate`` has a new field ``extra_help``
505
which can be set to add extra help to the error. (Gary van der Merwe)
507
* New method ``Branch.automatic_tag_name`` that can be used to find the
508
tag name for a particular revision automatically. (Jelmer Vernooij)
510
* The methods ``BzrDir.create_branch()``, ``BzrDir.destroy_branch()`` and
511
``BzrDir.open_branch()`` now take an optional ``name`` argument.
517
* bzr now has a ``.testr.conf`` file in its source tree configured
518
appropriately for running tests with Testrepository
519
(``https://launchpad.net/testrepository``). (Robert Collins)
521
* Documentation about testing with ``subunit`` has been tweaked.
524
* Known failures has been added for resolve --take-other on ParentLoop
525
conflicts. This reflects bug #537956 without fixing it.
528
* New ``bzrlib.tests.test_import_tariff`` can make assertions about what
529
Python modules are loaded, to guard against startup time or library
530
dependency regressions.
533
* PQM will now run with subunit output. To analyze a PQM error use
534
tribunal, or cat log | subunit-filter | subunit2pyunit. (Robert Collins)
536
* Stop sending apport crash files to ``.cache`` in the directory from
537
which ``bzr selftest`` was run. (Martin Pool, #422350)
539
* Tests no longer fail if "close() called during concurrent
540
operation on the same file object" occurs when closing the log file
541
(which can happen if a thread tries to write to the log file at the
542
wrong moment). An warning will be written to ``stderr`` when this
543
happens, and another warning will be written if the log file could not
544
be closed after retrying 100 times. (Andrew Bennetts, #531746)
549
:2.1.2: NOT RELEASED YET
554
* ``bzr switch`` does not die if a ConfigurableFileMerger is used.
555
(Aaron Bentley, #559436)
557
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
559
(Andrew Bennetts, #528041)
561
* Reset ``siginterrupt`` flag to False every time we handle a signal
562
installed with ``set_signal_handler(..., restart_syscall=True)`` (from
563
``bzrlib.osutils``. Reduces the likelihood of "Interrupted System Call"
564
errors after two window resizes.
570
* ``_remember_remote_is_before`` no longer raises AssertionError when
571
suboptimal network behaviour is noticed; instead it just mutters to the
572
log file (and warns the user if they have set the ``hpss`` debug flag).
573
This was causing unnecessary aborts for performance bugs that are minor
575
(Andrew Bennetts, #528041)
583
This is a small bugfix release. Upgrading is recommended for anyone
584
running 2.1.0 or earlier.
589
* Allow syscalls to automatically restart when ``TextUIFactory``'s
590
SIGWINCH handler is invoked, avoiding ``EINTR`` errors during blocking
591
IO, which are often poorly handled by Python's libraries and parts of
592
bzrlib. (Andrew Bennetts, #496813)
594
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
595
(Martin Pool, #331095)
597
* Fix plugin packaging on Windows. (Ian Clatworthy, #524162)
599
* Fix stub sftp test server to call os.getcwdu().
600
(Vincent Ladeuil, #526221, #526353)
602
* Fixed CHM generation by moving the NEWS section template into
603
a separate file. (Ian Clatworthy, #524184)
605
* Merge correctly when this_tree is not a WorkingTree. (Aaron Bentley)
607
* Register SIGWINCH handler only when creating a ``TextUIFactory``; avoids
608
problems importing bzrlib from a non-main thread.
609
(Elliot Murphy, #521989)
611
* Repositories accessed via a smart server now reject being stacked on a
612
repository in an incompatible format, as is the case when accessing them
613
via other methods. This was causing fetches from those repositories via
614
a smart server (e.g. using ``bzr branch``) to receive invalid data.
615
(Andrew Bennetts, #562380)
617
* Standardize the error handling when creating a new ``StaticTuple``
618
(problems will raise TypeError). (Matt Nordhoff, #457979)
620
* Warn if pyrex is too old to compile the new ``SimpleSet`` and
621
``StaticTuple`` extensions, rather than having the build fail randomly.
622
(John Arbash Meinel, #449776)
627
* Added a link to the Desktop Guide. (Ian Clatworthy)
629
* Added What's New in Bazaar 2.1 document. (Ian Clatworthy)
631
* Drop Google Analytics from the core docs as they caused problems
632
in the CHM files. (Ian Clatworthy, #502010)
637
* Added ``bzrlib.osutils.set_signal_handler``, a convenience function that
638
can set a signal handler and call ``signal.siginterrupt(signum,
639
False)`` for it, if the platform and Python version supports it.

:Codename: Strasbourg
649
This release marks our second long-term-stable series. The Bazaar team
650
has decided that we will continue to make bugfix-only 2.0.x and 2.1.x
651
releases, along with 2.2 development releases.
653
This is a fairly incremental update, focusing on polish and bugfixing.
654
There are no changes for supported disk formats. Key updates include
655
reduced memory consumption for many operations, a new per-file merge
656
hook, ignore patterns can now include '!' to exclude files, globbing
657
support for all commands on Windows, and support for addressing home
658
directories via ``bzr+ssh://host/~/`` syntax.
660
Users are encouraged to upgrade from the 2.0 stable series.
665
* Don't require testtools to use sftp.
666
(Vincent Ladeuil, #516183)
668
* Fix "AttributeError in Inter1and2Helper" during fetch.
669
(Martin Pool, #513432)
671
* ``bzr update`` performs the two merges in a more logical order and will stop
672
when it encounters conflicts.
673
(Gerard Krol, #113809)
675
* Give a better error message when doing ``bzr bind`` in an already bound
676
branch. (Neil Martinsen-Burrell, #513063)
678
* Ignore ``KeyError`` from ``remove_index`` during ``_abort_write_group``
679
in a pack repository, which can happen harmlessly if the abort occurs during
680
finishing the write group. Also use ``bzrlib.cleanup`` so that any
681
other errors that occur while aborting the individual packs won't be
682
hidden by secondary failures when removing the corresponding indices.
683
(Andrew Bennetts, #423015)
685
* Set the mtime of files exported to a directory by ``bzr export`` all to
686
the same value to avoid confusing ``make`` and other date-based build
687
systems. (Robert Collins, #515631)
692
* Fetching into experimental formats will now print a warning. (Jelmer
698
* ``Repository.deserialise_inventory`` has been renamed to
699
``Repository._deserialise_inventory`` to indicate it is private.
702
* ``Repository.get_inventory_xml`` has been renamed to
703
``Repository._get_inventory_xml`` to indicate it is private.
706
* ``Repository.serialise_inventory`` has been renamed to
707
``Repository._serialise_inventory`` to indicate it is private.
709
* Using the ``bzrlib.chk_map`` module from within multiple threads at the
710
same time was broken due to race conditions with a module level page
711
cache. This shows up as a KeyError in the ``bzrlib.lru_cache`` code with
712
``bzrlib.chk_map`` in the backtrace, and can be triggered without using
713
the same high level objects such as ``bzrlib.repository.Repository``
714
from different threads. chk_map now uses a thread local cache which may
715
increase memory pressure on processes using threads.
716
(Robert Collins, John Arbash Meinel, #514090)
718
* The new ``merge_file_content`` should now be ok with tests to avoid
720
(Vincent Ladeuil, #515597)
725
* Use ``bzrlib.cleanup`` rather than less robust ``try``/``finally``
726
blocks in several places in ``bzrlib.merge``. This avoids masking prior
727
errors when errors like ``ImmortalPendingDeletion`` occur during cleanup
729
(Andrew Bennetts, #517275)
734
* The ``remove_index`` method of
735
``bzrlib.repofmt.pack_repo.AggregateIndex`` no longer takes a ``pack``
736
argument. This argument was always ignored.
737
(Andrew Bennetts, #423015)
742
:Codename: after the bubbles
743
:2.1.0rc2: 2010-01-29
745
This is a quick-turn-around to update a small issue with our new per-file
746
merge hook. We expect no major changes from this to the final 2.1.0.
751
* The new ``merge_file_content`` hook point has been altered to provide a
752
better API where state for extensions can be stored rather than the
753
too-simple function based approach. This fixes a performance regression
754
where branch configuration would be parsed per-file during merge. As
755
part of this the included news_merger has been refactored into a base
756
helper class ``bzrlib.merge.ConfigurableFileMerger``.
757
(Robert Collins, John Arbash Meinel, #513822)

:Codename: the 'new' stable
764
:2.1.0rc1: 2009-01-21
766
This is the first stable release candidate for Bazaar's 2.1 series. From
767
this point onwards, the 2.1 series will be considered stable (as the 2.0
768
series) and only bugfixes are expected to be incorporated. The dozen or so
769
bugfixes in the 2.0.4 release are also included in this release (along
770
with more than 15 more bugfixes). Some of the interesting features are
771
support for per-file merge hooks, ``bzr unshelve --preview``, support
772
for using ! in ignore files to exclude files from being ignored, a small
773
memory leak was squashed, and many ``ObjectNotLocked`` errors were fixed.
774
This looks to be a very good start for a new stable series.
780
* Add bug information to log output when available.
781
(Neil Martinsen-Burrell, Guillermo Gonzalez, #251729)
783
* Added ``merge_file_content`` hook point to ``Merger``, allowing plugins
784
to register custom merge logic, e.g. to provide smarter merging for
787
* Bazaar now includes the ``news_merge`` plugin. It is disabled by
788
default, to enable it add a ``news_merge_files`` option to your
789
configuration. Consult ``bzr help news_merge`` for more information.
792
* ``bzr branch`` now takes a ``--bind`` option. This lets you
793
branch and bind all in one command. (Ian Clatworthy)
795
* ``bzr switch`` now takes a ``--revision`` option, to allow switching to
796
a specific revision of a branch. (Daniel Watkins, #183559)
798
* ``bzr unshelve --preview`` can now be used to show how a patch on the
799
shelf would be applied to the working tree.
800
(Guilherme Salgado, #308122)
802
* ``bzr update`` now takes a ``--revision`` argument. This lets you
803
change the revision of the working tree to any revision in the
804
ancestry of the current or master branch. (Matthieu Moy, Mark Hammond,
807
* ``-Dbytes`` can now be used to display the total number of bytes
808
transferred for the current command. This information is always logged
809
to ``.bzr.log`` for later inspection. (John Arbash Meinel)
811
* New ignore patterns. Patterns prefixed with '!' are exceptions to
812
ignore patterns and take precedence over regular ignores. Such
813
exceptions are used to specify files that should be versioned which
814
would otherwise be ignored. Patterns prefixed with '!!' act as regular
815
ignore patterns, but have highest precedence, even over the '!'
816
exception patterns. (John Whitley, #428031)
818
* The ``supress_warnings`` configuration option has been introduced to disable
819
various warnings (it currently only supports the ``format_deprecation``
820
warning). The new option can be set in any of the following locations:
821
``bazaar.conf``, ``locations.conf`` and/or ``branch.conf``.
822
(Ted Gould, Matthew Fuller, Vincent Ladeuil)
827
* Always show a message if an OS error occurs while trying to run a
828
user-specified commit message editor.
829
(Martin Pool, #504842)
831
* ``bzr diff`` will now use the epoch when it is unable to determine
832
the timestamp of a file, if the revision it was introduced in is a
833
ghost. (Jelmer Vernooij, #295611)
835
* ``bzr switch -b`` can now create branches that are located using directory
836
services such as ``lp:``, even when the branch name doesn't contain a
837
'/'. (Neil Martinsen-Burrell, #495263)
839
* ``bzr unshelve`` has improved messages about what it is doing.
840
(Neil Martinsen-Burrell, #496917)
842
* Concurrent autopacking is more resilient to already-renamed pack files.
843
If we find that a file we are about to obsolete is already obsoleted, we
844
do not try to rename it, and we leave the file in ``obsolete_packs``.
845
The code is also fault tolerant if a file goes missing, assuming that
846
another process already removed the file.
847
(John Arbash Meinel, Gareth White, #507557)
849
* Fix "Too many concurrent requests" in reconcile when network connection
850
fails. (Andrew Bennetts, #503878)
852
* Fixed a side effect mutation of ``RemoteBzrDirFormat._network_name``
853
that caused some tests to fail when run in a non-default order.
854
Probably no user impact. (Martin Pool, #504102)
856
* Fixed ``ObjectNotLocked`` error in ``bzr cat -rbranch:../foo FILE``.
857
(Andrew Bennetts, #506274)
859
* FTP transports support Unicode paths by encoding/decoding them as utf8.
860
(Vincent Ladeuil, #472161)
862
* Listen to the SIGWINCH signal to update the terminal width.
863
(Vincent Ladeuil, #316357)
865
* Progress bars are now hidden when ``--quiet`` is given.
866
(Martin Pool, #320035)
868
* ``SilentUIFactory`` now supports ``make_output_stream`` and discards
869
whatever is written to it. This un-breaks some plugin tests that
870
depended on this behaviour.
871
(Martin Pool, #499757)
873
* When operations update the working tree, all affected files should end
874
up with the same mtime. (eg. when versioning a generated file, if you
875
update the source and the generated file together, the generated file
876
should appear up-to-date.)
877
(John Arbash Meinel, Martin <gzlist>, #488724)
882
* Added ``add_cleanup`` and ``cleanup_now`` to ``bzrlib.command.Command``.
883
All the builtin commands now use ``add_cleanup`` rather than
884
``try``/``finally`` blocks where applicable as it is simpler and more
885
robust. (Andrew Bennetts)
887
* All except a small number of storage formats are now hidden, making
888
the help for numerous commands far more digestible. (Ian Clatworthy)
890
* Attempts to open a shared repository as a branch (e.g. ``bzr branch
891
path/to/repo``) will now include "location is a repository" as a hint in
892
the error message. (Brian de Alwis, Andrew Bennetts, #440952)
894
* Push will now inform the user when they are trying to push to a foreign
895
VCS for which roundtripping is not supported, and will suggest them to
896
use dpush. (Jelmer Vernooij)
898
* The version of bzr being run is now written to the log file.
901
* Transport network activity indicator is shown more of the time when
902
Bazaar is doing network IO.
908
* Add documentation on creating merges with more than one parent.
909
(Neil Martinsen-Burrell, #481526)
911
* Better explain the --uncommitted option of merge.
912
(Neil Martinsen-Burrell, #505088)
914
* Improve discussion of pending merges in the documentation for
915
``revert``. (Neil Martinsen-Burrell, #505093)
917
* Improved help for ``bzr send``.
918
(Martin Pool, Bojan Nikolic)
920
* There is a System Administrator's Guide in ``doc/en/admin-guide``,
921
including discussions of installation, relevant plugins, security and
922
backup. (Neil Martinsen-Burrell)
924
* The ``conflicts`` help topic has been renamed to ``conflict-types``.
927
* The User Reference is now presented as a series of topics.
928
Many of the included topics have link and format tweaks applied.
934
* Added ``cachedproperty`` decorator to ``bzrlib.decorators``.
937
* Many test features were renamed from ``FooFeature`` to ``foo_feature``
938
to be consistent with instances being lower case and classes being
939
CamelCase. For the features that were more likely to be used, we added a
940
deprecation thunk, but not all. (John Arbash Meinel)
942
* Merger classes (such as ``Merge3Merger``) now expect a ``this_branch``
943
parameter in their constructors, and provide ``this_branch`` as an
944
attribute. (Andrew Bennetts)
946
* The Branch hooks pre_change_branch_tip no longer masks exceptions raised
947
by plugins - the original exceptions are now preserved. (Robert Collins)
949
* The Transport ``Server.tearDown`` method is now renamed to
950
``stop_server`` and ``setUp`` to ``start_server`` for consistency with
951
our normal naming pattern, and to avoid confusion with Python's
952
``TestCase.tearDown``. (Martin Pool)
954
* ``WorkingTree.update`` implementations must now accept a ``revision``
960
* Added ``BzrDir.open_branchV3`` smart server request, which can receive
961
a string of details (such as "location is a repository") as part of a
962
``nobranch`` response. (Andrew Bennetts, #440952)
964
* New helper osutils.UnicodeOrBytesToBytesWriter which encodes unicode
965
objects but passes str objects straight through. This is used for
966
selftest but may be useful for diff and other operations that generate
967
mixed output. (Robert Collins)
969
* New exception ``NoRoundtrippingSupport``, for use by foreign branch
970
plugins. (Jelmer Vernooij)
975
* ``bzrlib.tests.permute_for_extension`` is a helper that simplifies
976
running all tests in the current module, once against a pure python
977
implementation, and once against an extension (pyrex/C) implementation.
978
It can be used to dramatically simplify the implementation of
979
``load_tests``. (John Arbash Meinel)
981
* ``bzrlib.tests.TestCase`` now subclasses ``testtools.testcase.TestCase``.
982
This permits features in testtools such as getUniqueInteger and
983
getUniqueString to be used. Because of this, testtools version 0.9.2 or
984
newer is now a dependency to run bzr selftest. Running with versions of
985
testtools less than 0.9.2 will cause bzr to error while loading the test
986
suite. (Robert Collins)
988
* Shell-like tests now support the command "mv" for moving files. The
989
syntax for ``mv file1 file2``, ``mv dir1 dir2`` and ``mv file dir`` is
990
supported. (Neil Martinsen-Burrell)
992
* The test progress bar no longer distinguishes tests that 'errored' from
993
tests that 'failed' - they're all just failures.
999
:2.0.6: NOT RELEASED YET
1004
* Additional merges after an unrelated branch has been merged with its
1005
history no longer crash when deleted files are involved.
1006
(Vincent Ladeuil, John Arbash Meinel, #375898)
1008
* ``bzr revert`` now only takes write lock on working tree, instead of on
1009
both working tree and branch.
1010
(Danny van Heumen, #498409)
1012
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
1013
permissions as ``.bzr`` directory on a POSIX OS.
1014
(Parth Malwankar, #262450)
1016
* Repositories accessed via a smart server now reject being stacked on a
1017
repository in an incompatible format, as is the case when accessing them
1018
via other methods. This was causing fetches from those repositories via
1019
a smart server (e.g. using ``bzr branch``) to receive invalid data.
1020
(Andrew Bennetts, #562380)
1027
This fifth release in our 2.0 series addresses several user-inconvenience
1028
bugs. None are critical, but upgrading is recommended for all users on
1029
earlier 2.0 releases.
1034
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
1035
(Martin Pool, #331095)
1037
* Concurrent autopacking is more resilient to already-renamed pack files.
1038
If we find that a file we are about to obsolete is already obsoleted, we
1039
do not try to rename it, and we leave the file in ``obsolete_packs``.
1040
The code is also fault tolerant if a file goes missing, assuming that
1041
another process already removed the file.
1042
(John Arbash Meinel, Gareth White, #507557)
1044
* Cope with the lockdir ``held/info`` file being empty, which seems to
1045
happen fairly often if the process is suddenly interrupted while taking
1047
(Martin Pool, #185103)
1049
* Give the warning about potentially slow cross-format fetches much
1050
earlier on in the fetch operation. Don't show this message during
1051
upgrades, and show the correct format indication for remote
1053
(Martin Pool, #456077, #515356, #513157)
1055
* Handle renames correctly when there are files or directories that
1056
differ only in case. (Chris Jones, Martin Pool, #368931)
1058
* If ``bzr push --create-prefix`` triggers an unexpected ``NoSuchFile``
1059
error, report that error rather than failing with an unhelpful
1060
``UnboundLocalError``.
1061
(Andrew Bennetts, #423563)
1063
* Running ``bzr`` command without any arguments now shows bzr
1064
version number along with rest of the help text.
1065
(Parth Malwankar, #369501)
1067
* Use osutils.O_NOINHERIT for some files on win32 to avoid PermissionDenied
1069
(Inada Naoki, #524560)
1074
* Added ``location-alias`` help topic.
1075
(Andrew Bennetts, #337834)
1077
* Fixed CHM generation by moving the NEWS section template into
1078
a separate file. (Ian Clatworthy, #524184)
1084
:Codename: smooth sailing
1087
The fourth bugfix-only release in the 2.0 series contains more than a
1088
dozen bugfixes relative to 2.0.3. The primary focus is on handling
1089
interruptions and concurrent operations more cleanly, there is also a fair
1090
improvement to ``bzr export`` when exporting a remote branch.
1096
* ``bzr annotate`` on another branch with ``-r branch:...`` no longer
1097
fails with an ``ObjectNotLocked`` error. (Andrew Bennetts, #496590)
1099
* ``bzr export dir`` now requests all file content as a record stream,
1100
rather than requsting the file content one file-at-a-time. This can make
1101
exporting over the network significantly faster (54min => 9min in one
1102
case). (John Arbash Meinel, #343218)
1104
* ``bzr serve`` no longer slowly leaks memory. The compiled
1105
``bzrlib.bencode.Encoder()`` class was using ``__del__`` to cleanup and
1106
free resources, and it should have been using ``__dealloc__``.
1107
This will likely have an impact on any other process that is serving for
1108
an extended period of time. (John Arbash Meinel, #494406)
1110
* Check for SIGINT (Ctrl-C) and other signals immediately if ``readdir``
1111
returns ``EINTR`` by calling ``PyErr_CheckSignals``. This affected the
1112
optional ``_readdir_pyx`` extension. (Andrew Bennetts, #495023)
1114
* Concurrent autopacks will no longer lose a newly created pack file.
1115
There was a race condition, where if the reload happened at the right
1116
time, the second packer would forget the name of the newly added pack
1117
file. (John Arbash Meinel, Gareth White, #507566)
1119
* Give a clearer message if the lockdir disappears after being apparently
1120
successfully taken. (Martin Pool, #498378)
1122
* Give a warning when fetching between repositories (local or remote) with
1123
sufficiently different formats that the content will need to be
1124
serialized (ie ``InterDifferingSerializer`` or ``inventory-deltas``), so
1125
the user has a clue that upgrading could make it faster.
1126
(Martin Pool, #456077)
1128
* If we fail to open ``~/.bzr.log`` write a clear message to stderr rather
1129
than using ``warning()``. The log file is opened before logging is set
1130
up, and it leads to very confusing: 'no handlers for "bzr"' messages for
1131
users, rather than something nicer.
1132
(John Arbash Meinel, Barry Warsaw, #503886)
1134
* Refuse to build with any Pyrex 0.9.4 release, as they have known bugs.
1135
(Martin Pool, John Arbash Meinel, #449372)
1137
* ``setup.py bdist_rpm`` now properly finds extra files needed for the
1138
build. (there is still the distutils bug
1139
http://bugs.python.org/issue644744) (Joe Julian, #175839)
1141
* The 2a format wasn't properly restarting autopacks when something
1142
changed underneath it (like another autopack). Now concurrent
1143
autopackers will properly succeed. (John Arbash Meinel, #495000)
1145
* ``TreeTransform`` can now handle when a delta says that the file id for
1146
the tree root changes. Rather than trying to rename your working
1147
directory, or failing early saying that you can't have multiple
1148
tree roots. This also fixes revert, update, and pull when the root id
1149
changes. (John Arbash Meinel, #494269, #504390)
1151
* ``_update_current_block`` no longer suppresses exceptions, so ^C at just
1152
the right time will get propagated, rather than silently failing to move
1153
the block pointer. (John Arbash Meinel, Gareth White, #495023)
1158
* We have a new ``test_source`` that ensures all pyrex ``cdef`` functions
1159
handle exceptions somehow. (Possibly by setting ``# cannot_raise``
1160
rather than an ``except ?:`` clause.) This should help prevent bugs like
1161
bug #495023. (John Arbash Meinel)

:2.1.0b4: 2009-12-14
1170
The fourth beta release in the 2.1 series brings with it a significant
1171
number of bugfixes (~20). The test suite is once again (finally) "green"
1172
on Windows, and should remain that way for future releases. There are a
1173
few performance related updates (faster upgrade and log), and several UI
1174
tweaks. There has also been a significant number of tweaks to the runtime
1175
documentation. 2.1.0b4 include everything from the 2.0.3 release.
1178
Compatibility Breaks
1179
********************
1181
* The BZR_SSH environmental variable may now be set to the path of a secure
1182
shell client. If currently set to the value ``ssh`` it will now guess the
1183
vendor of the program with that name, to restore the old behaviour that
1184
indicated the SSH Corporation client use ``sshcorp`` instead as the magic
1185
string. (Martin <gzlist@googlemail.com>, #176292)
1190
* ``bzr commit`` now has a ``--commit-time`` option.
1191
(Alexander Sack, #459276)
1193
* ``-Dhpss`` now increases logging done when run on the bzr server,
1194
similarly to how it works on the client. (John Arbash Meinel)
1196
* New option ``bzr unshelve --keep`` applies the changes and leaves them
1197
on the shelf. (Martin Pool, Oscar Fuentes, #492091)
1199
* The ``BZR_COLUMNS`` envrionment variable can be set to force bzr to
1200
respect a given terminal width. This can be useful when output is
1201
redirected or in obscure cases where the default value is not
1202
appropriate. Pagers can use it to get a better control of the line
1206
* The new command ``bzr lp-mirror`` will request that Launchpad update its
1207
mirror of a local branch. This command will only function if launchpadlib
1215
* After renaming a file, the dirstate could accidentally reference
1216
``source\\path`` rather than ``source/path`` on Windows. This might be a
1217
source of some dirstate-related failures. (John Arbash Meinel)
1219
* ``bzr commit`` now detects commit messages that looks like file names
1220
and issues a warning.
1221
(Gioele Barabucci, #73073)
1223
* ``bzr ignore /`` no longer causes an IndexError. (Gorden Tyler, #456036)
1225
* ``bzr log -n0 -rN`` should not return revisions beyond its merged revisions.
1226
(#325618, #484109, Marius Kruger)
1228
* ``bzr merge --weave`` and ``--lca`` will now create ``.BASE`` files for
1229
files with conflicts (similar to ``--merge3``). The contents of the file
1230
is a synthesis of all bases used for the merge.
1231
(John Arbash Meinel, #40412)
1233
* ``bzr mv --quiet`` really is quiet now. (Gordon Tyler, #271790)
1235
* ``bzr serve`` is more clear about the risk of supplying --allow-writes.
1236
(Robert Collins, #84659)
1238
* ``bzr serve --quiet`` really is quiet now. (Gordon Tyler, #252834)
1240
* Fix bug with redirected URLs over authenticated HTTP.
1241
(Glen Mailer, Neil Martinsen-Burrell, Vincent Ladeuil, #395714)
1243
* Interactive merge doesn't leave branch locks behind. (Aaron Bentley)
1245
* Lots of bugfixes for the test suite on Windows. We should once again
1246
have a test suite with no failures on Windows. (John Arbash Meinel)
1248
* ``osutils.terminal_width()`` obeys the BZR_COLUMNS environment
1249
variable but returns None if the terminal is not a tty (when output is
1250
redirected for example). Also fixes its usage under OSes that doesn't
1251
provide termios.TIOCGWINSZ. Make sure the corresponding tests runs on
1253
(Joke de Buhr, Vincent Ladeuil, #353370, #62539)
1254
(John Arbash Meinel, Vincent Ladeuil, #492561)
1256
* Terminate ssh subprocesses when no references to them remain, fixing
1257
subprocess and file descriptor leaks. (Andrew Bennetts, #426662)
1259
* The ``--hardlink`` option of ``bzr branch`` and ``bzr checkout`` now
1260
works for 2a format trees. Only files unaffected by content filters
1261
will be hardlinked. (Andrew Bennetts, #408193)
1263
* The new glob expansion on Windows would replace all ``\`` characters
1264
with ``/`` even if it there wasn't a glob to expand, the arg was quoted,
1265
etc. Now only change slashes if there is something being glob expanded.
1266
(John Arbash Meinel, #485771)
1268
* Use our faster ``KnownGraph.heads()`` functionality when computing the
1269
new rich-root heads. This can cut a conversion time in half (mysql from
1270
13.5h => 6.2h) (John Arbash Meinel, #487632)
1272
* When launching a external diff tool via bzr diff --using, temporary files
1273
are no longer created, rather, the path to the file in the working tree is
1274
passed to the external diff tool. This allows the file to be edited if the
1275
diff tool provides for this. (Gary van der Merwe, #490738)
1277
* The launchpad-open command can now be used from a subdirectory of a
1278
branch, not just from the root of the branch.
1279
(Neil Martinsen-Burrell, #489102)
1285
* ``bzr log`` is now faster. (Ian Clatworthy)
1287
* ``bzr update`` provides feedback on which branch it is up to date with.
1288
(Neil Martinsen-Burrell)
1290
* ``bzr upgrade`` from pre-2a to 2a can be significantly faster (4x).
1291
For details see the xml8 patch and heads() improvements.
1292
(John Arbash Meinel)
1294
* ``bzrlib.urlutils.local_path_from_url`` now accepts
1295
'file://localhost/' as well as 'file:///' URLs on POSIX. (Michael
1298
* The progress bar now shows only a spinner and per-operation counts,
1299
not an overall progress bar. The previous bar was often not correlated
1300
with real overall operation progress, either because the operations take
1301
nonlinear time, or because at the start of the operation Bazaar couldn't
1302
estimate how much work there was to do. (Martin Pool)
1307
* Lots of documentation tweaks for inline help topics and command help
1313
* ``bzrlib.textui`` (vestigial module) removed. (Martin Pool)
1315
* The Launchpad plugin now has a function ``login`` which will log in to
1316
Launchpad with launchpadlib, and ``load_branch`` which will return the
1317
Launchpad Branch object corresponding to a given Bazaar Branch object.
1323
* New test Feature: ``ModuleAvailableFeature``. It is designed to make it
1324
easier to handle what tests you want to run based on what modules can be
1325
imported. (Rather than lots of custom-implemented features that were
1326
basically copy-and-pasted.) (John Arbash Meinel)
1328
* ``osutils.timer_func()`` can be used to get either ``time.time()`` or
1329
``time.clock()`` when you want to do performance timing.
1330
``time.time()`` is limited to 15ms resolution on Windows, but
1331
``time.clock()`` gives CPU and not wall-clock time on other platforms.
1332
(John Arbash Meinel)
1334
* Several code paths that were calling ``Transport.get().read()`` have
1335
been changed to the equalivent ``Transport.get_bytes()``. The main
1336
difference is that the latter will explicitly call ``file.close()``,
1337
rather than expecting the garbage collector to handle it. This helps
1338
with some race conditions on Windows during the test suite and sftp
1339
tests. (John Arbash Meinel)
1344
* TestCaseWithMemoryTransport no longer sets $HOME and $BZR_HOME to
1345
unicode strings. (Michael Hudson, #464174)
1351
:Codename: little italy
1355
The third stable release of Bazaar has a small handful of bugfixes. As
1356
expected, this has no internal or external compatibility changes versus
1362
* ``bzr push --use-existing-dir`` no longer crashes if the directory
1363
exists but contains an invalid ``.bzr`` directory.
1364
(Andrew Bennetts, #423563)
1366
* Content filters are now applied correctly after pull, merge and switch.
1367
(Ian Clatworthy, #385879)
1369
* Fix a potential segfault in the groupcompress hash map handling code.
1370
When inserting new entries, if the final hash bucket was empty, we could
1371
end up trying to access if ``(last_entry+1)->ptr == NULL``.
1372
(John Arbash Meinel, #490228)
1374
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
1380
:Codename: after sprint recovery
1381
:2.1.0b3: 2009-11-16
1383
This release was pushed up from its normal release cycle due to a
1384
regression in python 2.4 compatibility in 2.1.0b2. Since this regression
1385
was caught before 2.1.0b2 was officially announced, the full changelog
1386
includes both 2.1.0b3 and 2.1.0b2 changes.
1388
Highlights of 2.1.0b3 are: new globbing code for all commands on Windows,
1389
the test suite now conforms to python's trunk enhanced semantics (skip,
1390
etc.), and ``bzr info -v`` will now report the correct branch and repo
1391
formats for Remote objects.
1397
* Users can define a shelve editor to provide shelf functionality at a
1398
granularity finer than per-patch-hunk. (Aaron Bentley)
1403
* Fix for shell completion and short options. (Benoît PIERRE)
1405
* Fix ``bzr --profile-imports`` with Python 2.6. (Martin Pool)
1407
* Hooks daughter classes should always call the base constructor.
1408
(Alexander Belchenko, Vincent Ladeuil, #389648)
1410
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
1412
* On Windows, do glob expansion at the command-line level (as is usually
1413
done in bash, etc.) This means that *all* commands get glob expansion
1414
(bzr status, bzr add, bzr mv, etc). It uses a custom command line
1415
parser, which allows us to know if a given section was quoted. It means
1416
you can now do ``bzr ignore "*.py"``.
1417
(John Arbash Meinel, #425510, #426410, #194450)
1419
* Sanitize commit messages that come in from the '-m' flag. We translate
1420
'\r\n' => '\n' and a plain '\r' => '\n'. The storage layer doesn't
1421
allow those because XML store silently translate it anyway. (The parser
1422
auto-translates \r\n => \n in ways that are hard for us to catch.)
1424
* Show correct branch and repository format descriptions in
1425
``bzr info -v`` on a smart server location. (Andrew Bennetts, #196080)
1427
* The fix for bug #186920 accidentally broke compatibility with python
1428
2.4. (Vincent Ladeuil, #475585)
1430
* Using ``Repository.get_commit_builder().record_iter_changes()`` now
1431
correctly sets ``self.inv_sha1`` to a sha1 string and
1432
``self.new_inventory`` to an Inventory instance after calling
1433
``self.finish_inventory()``. (Previously it accidently set both values
1434
as a tuple on ``self.inv_sha1``. This was missed because
1435
``repo.add_revision`` ignores the supplied inventory sha1 and recomputes
1436
the sha1 from the repo directly. (John Arbash Meinel)
1438
* Shelve command refuse to run if there is no real terminal.
1439
(Alexander Belchenko)
1441
* Avoid unnecessarily flushing of trace file; it's now unbuffered at the
1442
Python level. (Martin Pool)
1447
* Include Japanese translations for documentation (Inada Naoki)
1449
* New API ``ui_factory.make_output_stream`` to be used for sending bulk
1450
(rather than user-interaction) data to stdout. This automatically
1451
coordinates with progress bars or other terminal activity, and can be
1453
(Martin Pool, 493944)
1458
* Some of the core groupcompress functionality now releases the GIL before
1459
operation. Similar to how zlib and bz2 operate without the GIL in the
1460
core compression and decompression routines. (John Arbash Meinel)
1465
* -Dhpssvfs will now trigger on ``RemoteBzrDir._ensure_real``, providing
1466
more debugging of VFS access triggers. (Robert Collins)
1468
* KnownFailure is now signalled to ``ExtendedTestResult`` using the same
1469
method that Python 2.7 uses - ``addExpectedFailure``. (Robert Collins)
1471
* ``--parallel=fork`` is now compatible with --subunit.
1472
(Robert Collins, Vincent Ladeuil, #419776)
1474
* Reporting of failures shows test ids not descriptions and thus shows
1475
parameterised tests correctly. (Robert Collins)
1477
* TestNotApplicable is now handled within the TestCase.run method rather
1478
than being looked for within ``ExtendedTestResult.addError``. This
1479
provides better handling with other ``TestResult`` objects, degrading to
1480
sucess rather than error. (Robert Collins)
1482
* The private method ``_testConcluded`` on ``ExtendedTestResult`` has been
1483
removed - it was empty and unused. (Robert Collins)
1485
* UnavailableFeature is now handled within the TestCase.run method rather
1486
than being looked for within addError. If the Result object does not
1487
have an addNotSupported method, addSkip is attempted instead, and
1488
failing that addSuccess. (Robert Collins)
1490
* When a TestResult does not have an addSkip method, skipped tests are now
1491
reported as successful tests, rather than as errors. This change is
1492
to make it possible to get a clean test run with a less capable
1493
TestResult. (Robert Collins)
1500
:Codename: a load off my mind
1501
:2.1.0b2: 2009-11-02
1503
This is our second feature-filled release since 2.0, pushing us down the
1504
path to a 2.1.0. Once again, all bugfixes in 2.0.2 are present in 2.1.0b2.
1506
Key highlights in this release are: improved handling of
1507
failures-during-cleanup for commit, fixing a long-standing bug with
1508
``bzr+http`` and shared repositories, all ``lp:`` urls to be resolved
1509
behind proxies, and a new StaticTuple datatype, allowing us to reduce
1510
memory consumption (50%) and garbage collector overhead (40% faster) for
1513
* A new ``--concurrency`` option has been added as well as an associated
1514
BZR_CONCURRENCY environment variable to specify the number of
1515
processes that can be run concurrently when running ``bzr selftest``. The
1516
command-line option overrides the environment variable if both are
1517
specified. If none is specified. the number of processes is obtained
1518
from the OS as before. (Matt Nordhoff, Vincent Ladeuil)
1523
* ``bzr+http`` servers no longer give spurious jail break errors when
1524
serving branches inside a shared repository. (Andrew Bennetts, #348308)
1526
* Errors during commit are handled more robustly so that knock-on errors
1527
are less likely to occur, and will not obscure the original error if
1528
they do occur. This fixes some causes of ``TooManyConcurrentRequests``
1529
and similar errors. (Andrew Bennetts, #429747, #243391)
1531
* Launchpad urls can now be resolved from behind proxies.
1532
(Gordon Tyler, Vincent Ladeuil, #186920)
1534
* Reduce the strictness for StaticTuple, instead add a debug flag
1535
``-Dstatic_tuple`` which will change apis to be strict and raise errors.
1536
This way, most users won't see failures, but developers can improve
1537
internals. (John Arbash Meinel, #471193)
1539
* TreeTransform.adjust_path updates the limbo paths of descendants of adjusted
1540
files. (Aaron Bentley)
1542
* Unicode paths are now handled correctly and consistently by the smart
1543
server. (Andrew Bennetts, Michael Hudson, #458762)
1548
* When reading index files, we now use a ``StaticTuple`` rather than a
1549
plain ``tuple`` object. This generally gives a 20% decrease in peak
1550
memory, and can give a performance boost up to 40% on large projects.
1551
(John Arbash Meinel)
1553
* Peak memory under certain operations has been reduced significantly.
1554
(eg, 'bzr branch launchpad standalone' is cut in half)
1555
(John Arbash Meinel)
1560
* Filtered views user documentation upgraded to refer to format 2a
1561
instead of pre-2.0 formats. (Ian Clatworthy)
1566
* Remove deprecated ``CLIUIFactory``. (Martin Pool)
1568
* ``UIFactory`` now has new ``show_error``, ``show_message`` and
1569
``show_warning`` methods, which can be hooked by non-text UIs.
1575
* Added ``bzrlib._simple_set_pyx``. This is a hybrid between a Set and a
1576
Dict (it only holds keys, but you can lookup the object located at a
1577
given key). It has significantly reduced memory consumption versus the
1578
builtin objects (1/2 the size of Set, 1/3rd the size of Dict). This is
1579
used as the interning structure for StaticTuple objects.
1580
(John Arbash Meinel)
1582
* ``bzrlib._static_tuple_c.StaticTuple`` is now available and used by
1583
the btree index parser and the chk map parser. This class functions
1584
similarly to ``tuple`` objects. However, it can only point to a limited
1585
collection of types. (Currently StaticTuple, str, unicode, None, bool,
1586
int, long, float, but not subclasses). This allows us to remove it from
1587
the garbage collector (it cannot be in a cycle), it also allows us to
1588
intern the objects. In testing, this can reduce peak memory by 20-40%,
1589
and significantly improve performance by removing objects from being
1590
inspected by the garbage collector. (John Arbash Meinel)
1592
* ``GroupCompressBlock._ensure_content()`` will now release the
1593
``zlib.decompressobj()`` when the first request is for all of the
1594
content. (Previously it would only be released if you made a request for
1595
part of the content, and then all of it later.) This turns out to be a
1596
significant memory savings, as a ``zstream`` carries around approx 260kB
1597
of internal state and buffers. (For branching bzr.dev this drops peak
1598
memory from 382MB => 345MB.) (John Arbash Meinel)
1600
* When streaming content between ``2a`` format repositories, we now clear
1601
caches from earlier versioned files. (So 'revisions' is cleared when we
1602
start reading 'inventories', etc.) This can have a significant impact on
1603
peak memory for initial copies (~200MB). (John Arbash Meinel)
1609
:Codename: after the scare
1612
The second in our "let's keep the stable bugfixes flowing" series. As
1613
expected this has a few (~9) bugfixes relative to 2.0.1, and no major api
1614
changes or features.
1619
* Avoid "NoneType has no attribute st_mode" error when files disappear
1620
from a directory while it's being read. (Martin Pool, #446033)
1622
* Content filters are now applied correctly after revert.
1625
* Diff parsing handles "Binary files differ" hunks. (Aaron Bentley, #436325)
1627
* Fetching from stacked pre-2a repository via a smart server no longer
1628
fails intermittently with "second push failed to complete".
1629
(Andrew Bennetts, #437626)
1631
* Fix typos left after test_selftest refactoring.
1632
(Vincent Ladeuil, Matt Nordhoff, #461149)
1634
* Fixed ``ObjectNotLocked`` errors during ``bzr log -r NNN somefile``.
1635
(Andrew Bennetts, #445171)
1637
* PreviewTree file names are not limited by the encoding of the temp
1638
directory's filesystem. (Aaron Bentley, #436794)
1643
* ``bzr log`` now read-locks branches exactly once, so makes better use of
1644
data caches. (Andrew Bennetts)
1649
* Filtered views user documentation upgraded to refer to format 2a
1650
instead of pre-2.0 formats. (Ian Clatworthy)
1656
:Codename: While the cat is away
1657
:2.1.0b1: 2009-10-14
1659
This is the first development release in the new split "stable" and
1660
"development" series. As such, the release is a snapshot of bzr.dev
1661
without creating a release candidate first. This release includes a
1662
fair amount of internal changes, with deprecated code being removed,
1663
and several new feature developments. People looking for a stable code
1664
base with only bugfixes should focus on the 2.0.1 release. All bugfixes
1665
present in 2.0.1 are present in 2.1.0b1.
1667
Highlights include support for ``bzr+ssh://host/~/homedir`` style urls,
1668
finer control over the plugin search path via extended BZR_PLUGIN_PATH
1669
syntax, visible warnings when extension modules fail to load, and improved
1670
error handling during unlocking.
1676
* Bazaar can now send mail through Apple OS X Mail.app.
1679
* ``bzr+ssh`` and ``bzr`` paths can now be relative to home directories
1680
specified in the URL. Paths starting with a path segment of ``~`` are
1681
relative to the home directory of the user running the server, and paths
1682
starting with ``~user`` are relative to the home directory of the named
1683
user. For example, for a user "bob" with a home directory of
1684
``/home/bob``, these URLs are all equivalent:
1686
* ``bzr+ssh://bob@host/~/repo``
1687
* ``bzr+ssh://bob@host/~bob/repo``
1688
* ``bzr+ssh://bob@host/home/bob/repo``
1690
If ``bzr serve`` was invoked with a ``--directory`` argument, then no
1691
home directories outside that directory will be accessible via this
1694
This is a feature of ``bzr serve``, so pre-2.1 clients will
1695
automatically benefit from this feature when ``bzr`` on the server is
1696
upgraded. (Andrew Bennetts, #109143)
1698
* Extensions can now be compiled if either Cython or Pyrex is available.
1699
Currently Pyrex is preferred, but that may change in the future.
1702
* Give more control on BZR_PLUGIN_PATH by providing a way to refer to or
1703
disable the user, site and core plugin directories.
1704
(Vincent Ladeuil, #412930, #316192, #145612)
1709
* Bazaar's native protocol code now correctly handles EINTR, which most
1710
noticeably occurs if you break in to the debugger while connected to a
1711
bzr+ssh server. You can now can continue from the debugger (by typing
1712
'c') and the process continues. However, note that pressing C-\ in the
1713
shell may still kill the SSH process, which is bug 162509, so you must
1714
sent a signal to the bzr process specifically, for example by typing
1715
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
1717
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
1718
filename will issue a warning and skip over those files.
1719
(Robert Collins, #3918)
1721
* ``bzr dpush`` now aborts if uncommitted changes (including pending merges)
1722
are present in the working tree. The configuration option ``dpush_strict``
1723
can be used to set the default for this behavior.
1724
(Vincent Ladeuil, #438158)
1726
* ``bzr merge`` and ``bzr remove-tree`` now requires --force if pending
1727
merges are present in the working tree.
1728
(Vincent Ladeuil, #426344)
1730
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
1731
traceback. (Martin Pool, #109115)
1733
* Don't give a warning on Windows when failing to import ``_readdir_pyx``
1734
as it is never built. (John Arbash Meinel, #430645)
1736
* Don't restrict the command name used to run the test suite.
1737
(Vincent Ladeuil, #419950)
1739
* ftp transports were built differently when the kerberos python module was
1740
present leading to obscure failures related to ASCII/BINARY modes.
1741
(Vincent Ladeuil, #443041)
1743
* Network streams now decode adjacent records of the same type into a
1744
single stream, reducing layering churn. (Robert Collins)
1746
* PreviewTree behaves correctly when get_file_mtime is invoked on an unmodified
1747
file. (Aaron Bentley, #251532)
1749
* Registry objects should not use iteritems() when asked to use items().
1750
(Vincent Ladeuil, #430510)
1752
* Weave based repositories couldn't be cloned when committers were using
1753
domains or user ids embedding '.sig'. Now they can.
1754
(Matthew Fuller, Vincent Ladeuil, #430868)
1759
* Revision specifiers can now be given in a more DWIM form, without
1760
needing explicit prefixes for specifiers like tags or revision id's.
1761
See ``bzr help revisionspec`` for full details. (Matthew Fuller)
1763
* Bazaar gives a warning before exiting, and writes into ``.bzr.log``, if
1764
compiled extensions can't be loaded. This typically indicates a
1765
packaging or installation problem. In this case Bazaar will keep
1766
running using pure-Python versions, but this may be substantially
1767
slower. The warning can be disabled by setting
1768
``ignore_missing_extensions = True`` in ``bazaar.conf``.

1770
(Martin Pool, #406113, #430529)
1772
* Secondary errors that occur during Branch.unlock and Repository.unlock
1773
no longer obscure the original error. These methods now use a new
1774
decorator, ``only_raises``. This fixes many causes of
1775
``TooManyConcurrentRequests`` and similar errors.
1776
(Andrew Bennetts, #429747)
1781
* Describe the new shell-like test feature. (Vincent Ladeuil)
1783
* Help on hooks no longer says 'Not deprecated' for hooks that are
1784
currently supported. (Ian Clatworthy, #422415)
1789
* ``bzrlib.user_encoding`` has been removed; use
1790
``bzrlib.osutils.get_user_encoding`` instead. (Martin Pool)
1792
* ``bzrlib.tests`` now uses ``stopTestRun`` for its ``TestResult``
1793
subclasses - the same as python's unittest module. (Robert Collins)
1795
* ``diff._get_trees_to_diff`` has been renamed to
1796
``diff.get_trees_and_branches_to_diff``. It is now a public API, and it
1797
returns the old and new branches. (Gary van der Merwe)
1799
* ``bzrlib.trace.log_error``, ``error`` and ``info`` have been deprecated.
1802
* ``MutableTree.has_changes()`` does not require a tree parameter anymore. It
1803
now defaults to comparing to the basis tree. It now checks for pending
1804
merges too. ``Merger.check_basis`` has been deprecated and replaced by the
1805
corresponding has_changes() calls. ``Merge.compare_basis``,
1806
``Merger.file_revisions`` and ``Merger.ensure_revision_trees`` have also
1808
(Vincent Ladeuil, #440631)
1810
* ``ProgressTask.note`` is deprecated.
1816
* Added ``-Drelock`` debug flag. It will ``note`` a message every time a
1817
repository or branch object is unlocked then relocked the same way.
1820
* ``BTreeLeafParser.extract_key`` has been tweaked slightly to reduce
1821
mallocs while parsing the index (approx 3=>1 mallocs per key read).
1822
This results in a 10% speedup while reading an index.
1823
(John Arbash Meinel)
1825
* The ``bzrlib.lsprof`` module has a new class ``BzrProfiler`` which makes
1826
profiling in some situations like callbacks and generators easier.
1832
* Passing ``--lsprof-tests -v`` to bzr selftest will cause lsprof output to
1833
be output for every test. Note that this is very verbose! (Robert Collins)
1835
* Setting ``BZR_TEST_PDB=1`` when running selftest will cause a pdb
1836
post_mortem to be triggered when a test failure occurs. (Robert Collins)
1838
* Shell-like tests can now be written. Code in ``bzrlib/tests/script.py`` ,
1839
documentation in ``developers/testing.txt`` for details.
1842
* Some tests could end up with the same id, that was dormant for
1844
(Vincent Ladeuil, #442980)
1846
* Stop showing the number of tests due to missing features in the test
1847
progress bar. (Martin Pool)
1849
* Test parameterisation now does a shallow copy, not a deep copy of the test
1850
to be parameterised. This is not expected to break external use of test
1851
parameterisation, and is substantially faster. (Robert Collins)
1853
* Tests that try to open a bzr dir on an arbitrary transport will now
1854
fail unless they have explicitly permitted the transport via
1855
``self.permit_url``. The standard test factories such as ``self.get_url``
1856
will permit the urls they provide automatically, so only exceptional
1857
tests should need to do this. (Robert Collins)
1859
* The break-in test no longer cares about clean shutdown of the child,
1860
instead it is happy if the debugger starts up. (Robert Collins)
1862
* The full test suite is expected to pass when the C extensions are not
1863
present. (Vincent Ladeuil, #430749)
1869
:Codename: Stability First
1872
The first of our new ongoing bugfix-only stable releases has arrived. It
1873
includes a collection of 12 bugfixes applied to bzr 2.0.0, but does not
1874
include any of the feature development in the 2.1.0 series.
1880
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
1881
filename will issue a warning and skip over those files.
1882
(Robert Collins, #3918)
1884
* bzr will attempt to authenticate with SSH servers that support
1885
``keyboard-interactive`` auth but not ``password`` auth when using
1886
Paramiko. (Andrew Bennetts, #433846)
1888
* Fixed fetches from a stacked branch on a smart server that were failing
1889
with some combinations of remote and local formats. This was causing
1890
"unknown object type identifier 60" errors. (Andrew Bennetts, #427736)
1892
* Fixed ``ObjectNotLocked`` errors when doing some log and diff operations
1893
on branches via a smart server. (Andrew Bennetts, #389413)
1895
* Handle things like ``bzr add foo`` and ``bzr rm foo`` when the tree is
1896
at the root of a drive. ``osutils._cicp_canonical_relpath`` always
1897
assumed that ``abspath()`` returned a path that did not have a trailing
1898
``/``, but that is not true when working at the root of the filesystem.
1899
(John Arbash Meinel, Jason Spashett, #322807)
1901
* Hide deprecation warnings for 'final' releases for python2.6.
1902
(John Arbash Meinel, #440062)
1904
* Improve the time for ``bzr log DIR`` for 2a format repositories.
1905
We had been using the same code path as for <2a formats, which required
1906
iterating over all objects in all revisions.
1907
(John Arbash Meinel, #374730)
1909
* Make sure that we unlock the tree if we fail to create a TreeTransform
1910
object when doing a merge, and there is limbo, or pending-deletions
1911
directory. (Gary van der Merwe, #427773)
1913
* Occasional IndexError on renamed files have been fixed. Operations that
1914
set a full inventory in the working tree will now go via the
1915
apply_inventory_delta code path which is simpler and easier to
1916
understand than dirstates set_state_from_inventory method. This may
1917
have a small performance impact on operations built on _write_inventory,
1918
but such operations are already doing full tree scans, so no radical
1919
performance change should be observed. (Robert Collins, #403322)
1921
* Retrieving file text or mtime from a _PreviewTree has good performance when
1922
there are many changes. (Aaron Bentley)
1924
* The CHK index pages now use an unlimited cache size. With a limited
1925
cache and a large project, the random access of chk pages could cause us
1926
to download the entire cix file many times.
1927
(John Arbash Meinel, #402623)
1929
* When a file kind becomes unversionable after being added, a sensible
1930
error will be shown instead of a traceback. (Robert Collins, #438569)
1935
* Improved README. (Ian Clatworthy)
1937
* Improved upgrade documentation for Launchpad branches.
1945
:Codename: Instant Karma
1947
This release of Bazaar makes the 2a (previously 'brisbane-core') format
1948
the default when new branches or repositories are created. This format is
1949
substantially smaller and faster for many operations. Most of the work in
1950
this release focuses on bug fixes and stabilization, covering both 2a and
1951
previous formats. (See the Upgrade Guide for information on migrating
1954
This release also improves the documentation content and presentation,
1955
including adding Windows HtmlHelp manuals.
1957
The Bazaar team decided that 2.0 will be a long-term supported release,
1958
with bugfix-only 2.0.x releases based on it, continuing for at least six
1959
months or until the following stable release.
1961
Changes from 2.0.0rc2 to final
1962
******************************
1964
* Officially branded as 2.0.0 rather than 2.0 to clarify between things
1965
that "want to happen on the 2.0.x stable series" versus things that want
1966
to "land in 2.0.0". (Changes how bzrlib._format_version_tuple() handles
1967
micro = 0.) (John Arbash Meinel)
1973
:2.0.0rc2: 2009-09-10
1978
* Added post_commit hook for mutable trees. This allows the keywords
1979
plugin to expand keywords on files changed by the commit.
1980
(Ian Clatworthy, #408841)
1985
* Bazaar's native protocol code now correctly handles EINTR, which most
1986
noticeably occurs if you break in to the debugger while connected to a
1987
bzr+ssh server. You can now can continue from the debugger (by typing
1988
'c') and the process continues. However, note that pressing C-\ in the
1989
shell may still kill the SSH process, which is bug 162509, so you must
1990
sent a signal to the bzr process specifically, for example by typing
1991
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
1993
* ``bzr check`` in pack-0.92, 1.6 and 1.9 format repositories will no
1994
longer report incorrect errors about ``Missing inventory ('TREE_ROOT', ...)``
1995
(Robert Collins, #416732)
1997
* ``bzr info -v`` on a 2a format still claimed that it was a "Development
1998
format" (John Arbash Meinel, #424392)
2000
* ``bzr log stacked-branch`` shows the full log including
2001
revisions that are in the fallback repository. (Regressed in 2.0rc1).
2002
(John Arbash Meinel, #419241)
2004
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
2005
traceback. (Martin Pool, #109115)
2007
* Conversion to 2a will create a single pack for all the new revisions (as
2008
long as it ran without interruption). This improves both ``bzr upgrade``
2009
and ``bzr pull`` or ``bzr merge`` from local branches in older formats.
2010
The autopack logic that occurs every 100 revisions during local
2011
conversions was not returning that pack's identifier, which resulted in
2012
the partial packs created during the conversion not being consolidated
2013
at the end of the conversion process. (Robert Collins, #423818)
2015
* Fetches from 2a to 2a are now again requested in 'groupcompress' order.
2016
Groups that are seen as 'underutilized' will be repacked on-the-fly.
2017
This means that when the source is fully packed, there is minimal
2018
overhead during the fetch, but if the source is poorly packed the result
2019
is a fairly well packed repository (not as good as 'bzr pack' but
2020
good-enough.) (Robert Collins, John Arbash Meinel, #402652)
2022
* Fix a potential segmentation fault when doing 'log' of a branch that had
2023
ghosts in its mainline. (Evaluating None as a tuple is bad.)
2024
(John Arbash Meinel, #419241)
2026
* ``groupcompress`` sort order is now more stable, rather than relying on
2027
``topo_sort`` ordering. The implementation is now
2028
``KnownGraph.gc_sort``. (John Arbash Meinel)
2030
* Local data conversion will generate correct deltas. This is a critical
2031
bugfix vs 2.0rc1, and all 2.0rc1 users should upgrade to 2.0rc2 before
2032
converting repositories. (Robert Collins, #422849)
2034
* Network streams now decode adjacent records of the same type into a
2035
single stream, reducing layering churn. (Robert Collins)
2037
* Prevent some kinds of incomplete data from being committed to a 2a
2038
repository, such as revisions without inventories, a missing chk_bytes
2039
record for an inventory, or a missing text referenced by an inventory.
2040
(Andrew Bennetts, #423506, #406687)
2045
* Fix assertion error about "_remember_remote_is_before" when pushing to
2046
older smart servers.
2047
(Andrew Bennetts, #418931)
2049
* Help on hooks no longer says 'Not deprecated' for hooks that are
2050
currently supported. (Ian Clatworthy, #422415)
2052
* PDF and CHM (Windows HtmlHelp) formats are now supported for the
2053
user documentation. The HTML documentation is better broken up into
2054
topics. (Ian Clatworthy)
2056
* The developer and foreign language documents are now separated
2057
out so that searching in the HTML and CHM files produces more
2058
useful results. (Ian Clatworthy)
2060
* The main table of contents now provides links to the new Migration Docs
2061
and Plugins Guide. (Ian Clatworthy)
