The sixth release in our 2.0 series addresses several user-inconvenience
14
bugs. None are critical, but upgrading is recommended for all users on
20
* Additional merges after an unrelated branch has been merged with its
21
history no longer crash when deleted files are involved.
22
(Vincent Ladeuil, John Arbash Meinel, #375898)
24
* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
25
previously-unversioned directory within the tree: the directory is
27
(Martin Pool, #192859)
29
* ``bzr commit SYMLINK`` now works, rather than trying to commit the
30
target of the symlink.
31
(Martin Pool, John Arbash Meinel, #128562)
33
* ``bzr revert`` now only takes write lock on working tree, instead of on
34
both working tree and branch.
35
(Danny van Heumen, #498409)
37
* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
38
permissions as ``.bzr`` directory on a POSIX OS.
39
(Parth Malwankar, #262450)
41
* Don't traceback trying to unversion children files of an already
42
unversioned directory. (Vincent Ladeuil, #494221)
44
* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
45
contains only NUL bytes). Instead warn the user, and allow ``bzr
46
break-lock`` to remove it. (Andrew Bennetts, #619872)
48
* Fix ``AttributeError on parent.children`` when adding a file under a
49
directory that was a symlink in the previous commit.
50
(Martin Pool, #192859)
52
* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
53
which can result in "missing referenced chk root keys" errors when
54
fetching from repositories with affected revisions.
55
(Andrew Bennetts, #522637)
57
* Raise ValueError instead of a string exception.
58
(John Arbash Meinel, #586926)
60
* Reduce peak memory by one copy of compressed text.
61
(John Arbash Meinel, #566940)
63
* Repositories accessed via a smart server now reject being stacked on a
64
repository in an incompatible format, as is the case when accessing them
65
via other methods. This was causing fetches from those repositories via
66
a smart server (e.g. using ``bzr branch``) to receive invalid data.
67
(Andrew Bennetts, #562380)
69
* Selftest with versions of subunit that support ``stopTestRun`` will no longer
70
error. This error was caused by 2.0 not being updated when upstream
71
python merged the end of run patch, which chose ``stopTestRun`` rather than
72
``done``. (Robert Collins, #571437)
74
* When passing a file to ``UTF8DirReader`` make sure to close the current
75
directory file handle after the chdir fails. Otherwise when passing many
76
filenames into a command line ``bzr status`` we would leak descriptors.
77
(John Arbash Meinel, #583486)
83
* ``build_tree_contents`` can create symlinks.
84
(Martin Pool, John Arbash Meinel)
92
This fifth release in our 2.0 series addresses several user-inconvenience
93
bugs. None are critical, but upgrading is recommended for all users on
99
* Avoid ``malloc(0)`` in ``patiencediff``, which is non-portable.
100
(Martin Pool, #331095)
102
* Concurrent autopacking is more resilient to already-renamed pack files.
103
If we find that a file we are about to obsolete is already obsoleted, we
104
do not try to rename it, and we leave the file in ``obsolete_packs``.
105
The code is also fault tolerant if a file goes missing, assuming that
106
another process already removed the file.
107
(John Arbash Meinel, Gareth White, #507557)
109
* Cope with the lockdir ``held/info`` file being empty, which seems to
110
happen fairly often if the process is suddenly interrupted while taking
112
(Martin Pool, #185103)
114
* Give the warning about potentially slow cross-format fetches much
115
earlier on in the fetch operation. Don't show this message during
116
upgrades, and show the correct format indication for remote
118
(Martin Pool, #456077, #515356, #513157)
120
* Handle renames correctly when there are files or directories that
121
differ only in case. (Chris Jones, Martin Pool, #368931)
123
* If ``bzr push --create-prefix`` triggers an unexpected ``NoSuchFile``
124
error, report that error rather than failing with an unhelpful
125
``UnboundLocalError``.
126
(Andrew Bennetts, #423563)
128
* Running ``bzr`` command without any arguments now shows bzr
129
version number along with rest of the help text.
130
(Parth Malwankar, #369501)
132
* Use osutils.O_NOINHERIT for some files on win32 to avoid PermissionDenied
134
(Inada Naoki, #524560)
139
* Added ``location-alias`` help topic.
140
(Andrew Bennetts, #337834)
142
* Fixed CHM generation by moving the NEWS section template into
143
a separate file. (Ian Clatworthy, #524184)
149
:Codename: smooth sailing
152
The fourth bugfix-only release in the 2.0 series contains more than a
153
dozen bugfixes relative to 2.0.3. The primary focus is on handling
154
interruptions and concurrent operations more cleanly, there is also a fair
155
improvement to ``bzr export`` when exporting a remote branch.
161
* ``bzr annotate`` on another branch with ``-r branch:...`` no longer
162
fails with an ``ObjectNotLocked`` error. (Andrew Bennetts, #496590)
164
* ``bzr export dir`` now requests all file content as a record stream,
165
rather than requsting the file content one file-at-a-time. This can make
166
exporting over the network significantly faster (54min => 9min in one
167
case). (John Arbash Meinel, #343218)
169
* ``bzr serve`` no longer slowly leaks memory. The compiled
170
``bzrlib.bencode.Encoder()`` class was using ``__del__`` to cleanup and
171
free resources, and it should have been using ``__dealloc__``.
172
This will likely have an impact on any other process that is serving for
173
an extended period of time. (John Arbash Meinel, #494406)
175
* Check for SIGINT (Ctrl-C) and other signals immediately if ``readdir``
176
returns ``EINTR`` by calling ``PyErr_CheckSignals``. This affected the
177
optional ``_readdir_pyx`` extension. (Andrew Bennetts, #495023)
179
* Concurrent autopacks will no longer lose a newly created pack file.
180
There was a race condition, where if the reload happened at the right
181
time, the second packer would forget the name of the newly added pack
182
file. (John Arbash Meinel, Gareth White, #507566)
184
* Give a clearer message if the lockdir disappears after being apparently
185
successfully taken. (Martin Pool, #498378)
187
* Give a warning when fetching between repositories (local or remote) with
188
sufficiently different formats that the content will need to be
189
serialized (ie ``InterDifferingSerializer`` or ``inventory-deltas``), so
190
the user has a clue that upgrading could make it faster.
191
(Martin Pool, #456077)
193
* If we fail to open ``~/.bzr.log`` write a clear message to stderr rather
194
than using ``warning()``. The log file is opened before logging is set
195
up, and it leads to very confusing: 'no handlers for "bzr"' messages for
196
users, rather than something nicer.
197
(John Arbash Meinel, Barry Warsaw, #503886)
199
* Refuse to build with any Pyrex 0.9.4 release, as they have known bugs.
200
(Martin Pool, John Arbash Meinel, #449372)
202
* ``setup.py bdist_rpm`` now properly finds extra files needed for the
203
build. (there is still the distutils bug
204
http://bugs.python.org/issue644744) (Joe Julian, #175839)
206
* The 2a format wasn't properly restarting autopacks when something
207
changed underneath it (like another autopack). Now concurrent
208
autopackers will properly succeed. (John Arbash Meinel, #495000)
210
* ``TreeTransform`` can now handle when a delta says that the file id for
211
the tree root changes. Rather than trying to rename your working
212
directory, or failing early saying that you can't have multiple
213
tree roots. This also fixes revert, update, and pull when the root id
214
changes. (John Arbash Meinel, #494269, #504390)
216
* ``_update_current_block`` no longer suppresses exceptions, so ^C at just
217
the right time will get propagated, rather than silently failing to move
218
the block pointer. (John Arbash Meinel, Gareth White, #495023)
223
* We have a new ``test_source`` that ensures all pyrex ``cdef`` functions
224
handle exceptions somehow. (Possibly by setting ``# cannot_raise``
225
rather than an ``except ?:`` clause.) This should help prevent bugs like
226
bug #495023. (John Arbash Meinel)
232
:Codename: little italy
236
The third stable release of Bazaar has a small handful of bugfixes. As
237
expected, this has no internal or external compatibility changes versus
243
* ``bzr push --use-existing-dir`` no longer crashes if the directory
244
exists but contains an invalid ``.bzr`` directory.
245
(Andrew Bennetts, #423563)
247
* Content filters are now applied correctly after pull, merge and switch.
248
(Ian Clatworthy, #385879)
250
* Fix a potential segfault in the groupcompress hash map handling code.
251
When inserting new entries, if the final hash bucket was empty, we could
252
end up trying to access if ``(last_entry+1)->ptr == NULL``.
253
(John Arbash Meinel, #490228)
255
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
261
:Codename: after the scare
264
The second in our "let's keep the stable bugfixes flowing" series. As
265
expected this has a few (~9) bugfixes relative to 2.0.1, and no major api
271
* Avoid "NoneType has no attribute st_mode" error when files disappear
272
from a directory while it's being read. (Martin Pool, #446033)
274
* Content filters are now applied correctly after revert.
277
* Diff parsing handles "Binary files differ" hunks. (Aaron Bentley, #436325)
279
* Fetching from stacked pre-2a repository via a smart server no longer
280
fails intermittently with "second push failed to complete".
281
(Andrew Bennetts, #437626)
283
* Fix typos left after test_selftest refactoring.
284
(Vincent Ladeuil, Matt Nordhoff, #461149)
286
* Fixed ``ObjectNotLocked`` errors during ``bzr log -r NNN somefile``.
287
(Andrew Bennetts, #445171)
289
* PreviewTree file names are not limited by the encoding of the temp
290
directory's filesystem. (Aaron Bentley, #436794)
295
* ``bzr log`` now read-locks branches exactly once, so makes better use of
296
data caches. (Andrew Bennetts)
301
* Filtered views user documentation upgraded to refer to format 2a
302
instead of pre-2.0 formats. (Ian Clatworthy)
308
:Codename: Stability First
311
The first of our new ongoing bugfix-only stable releases has arrived. It
312
includes a collection of 12 bugfixes applied to bzr 2.0.0, but does not
313
include any of the feature development in the 2.1.0 series.
319
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
320
filename will issue a warning and skip over those files.
321
(Robert Collins, #3918)
323
* bzr will attempt to authenticate with SSH servers that support
324
``keyboard-interactive`` auth but not ``password`` auth when using
325
Paramiko. (Andrew Bennetts, #433846)
327
* Fixed fetches from a stacked branch on a smart server that were failing
328
with some combinations of remote and local formats. This was causing
329
"unknown object type identifier 60" errors. (Andrew Bennetts, #427736)
331
* Fixed ``ObjectNotLocked`` errors when doing some log and diff operations
332
on branches via a smart server. (Andrew Bennetts, #389413)
334
* Handle things like ``bzr add foo`` and ``bzr rm foo`` when the tree is
335
at the root of a drive. ``osutils._cicp_canonical_relpath`` always
336
assumed that ``abspath()`` returned a path that did not have a trailing
337
``/``, but that is not true when working at the root of the filesystem.
338
(John Arbash Meinel, Jason Spashett, #322807)
340
* Hide deprecation warnings for 'final' releases for python2.6.
341
(John Arbash Meinel, #440062)
343
* Improve the time for ``bzr log DIR`` for 2a format repositories.
344
We had been using the same code path as for <2a formats, which required
345
iterating over all objects in all revisions.
346
(John Arbash Meinel, #374730)
348
* Make sure that we unlock the tree if we fail to create a TreeTransform
349
object when doing a merge, and there is limbo, or pending-deletions
350
directory. (Gary van der Merwe, #427773)
352
* Occasional IndexError on renamed files have been fixed. Operations that
353
set a full inventory in the working tree will now go via the
354
apply_inventory_delta code path which is simpler and easier to
355
understand than dirstates set_state_from_inventory method. This may
356
have a small performance impact on operations built on _write_inventory,
357
but such operations are already doing full tree scans, so no radical
358
performance change should be observed. (Robert Collins, #403322)
360
* Retrieving file text or mtime from a _PreviewTree has good performance when
361
there are many changes. (Aaron Bentley)
363
* The CHK index pages now use an unlimited cache size. With a limited
364
cache and a large project, the random access of chk pages could cause us
365
to download the entire cix file many times.
366
(John Arbash Meinel, #402623)
368
* When a file kind becomes unversionable after being added, a sensible
369
error will be shown instead of a traceback. (Robert Collins, #438569)
374
* Improved README. (Ian Clatworthy)
376
* Improved upgrade documentation for Launchpad branches.
384
:Codename: Instant Karma
386
This release of Bazaar makes the 2a (previously 'brisbane-core') format
387
the default when new branches or repositories are created. This format is
388
substantially smaller and faster for many operations. Most of the work in
389
this release focuses on bug fixes and stabilization, covering both 2a and
390
previous formats. (See the Upgrade Guide for information on migrating
393
This release also improves the documentation content and presentation,
394
including adding Windows HtmlHelp manuals.
396
The Bazaar team decided that 2.0 will be a long-term supported release,
397
with bugfix-only 2.0.x releases based on it, continuing for at least six
398
months or until the following stable release.
400
Changes from 2.0.0rc2 to final
401
******************************
403
* Officially branded as 2.0.0 rather than 2.0 to clarify between things
404
that "want to happen on the 2.0.x stable series" versus things that want
405
to "land in 2.0.0". (Changes how bzrlib._format_version_tuple() handles
406
micro = 0.) (John Arbash Meinel)
412
:2.0.0rc2: 2009-09-10
417
* Added post_commit hook for mutable trees. This allows the keywords
418
plugin to expand keywords on files changed by the commit.
419
(Ian Clatworthy, #408841)
424
* Bazaar's native protocol code now correctly handles EINTR, which most
425
noticeably occurs if you break in to the debugger while connected to a
426
bzr+ssh server. You can now can continue from the debugger (by typing
427
'c') and the process continues. However, note that pressing C-\ in the
428
shell may still kill the SSH process, which is bug 162509, so you must
429
sent a signal to the bzr process specifically, for example by typing
430
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
432
* ``bzr check`` in pack-0.92, 1.6 and 1.9 format repositories will no
433
longer report incorrect errors about ``Missing inventory ('TREE_ROOT', ...)``
434
(Robert Collins, #416732)
436
* ``bzr info -v`` on a 2a format still claimed that it was a "Development
437
format" (John Arbash Meinel, #424392)
439
* ``bzr log stacked-branch`` shows the full log including
440
revisions that are in the fallback repository. (Regressed in 2.0rc1).
441
(John Arbash Meinel, #419241)
443
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
444
traceback. (Martin Pool, #109115)
446
* Conversion to 2a will create a single pack for all the new revisions (as
447
long as it ran without interruption). This improves both ``bzr upgrade``
448
and ``bzr pull`` or ``bzr merge`` from local branches in older formats.
449
The autopack logic that occurs every 100 revisions during local
450
conversions was not returning that pack's identifier, which resulted in
451
the partial packs created during the conversion not being consolidated
452
at the end of the conversion process. (Robert Collins, #423818)
454
* Fetches from 2a to 2a are now again requested in 'groupcompress' order.
455
Groups that are seen as 'underutilized' will be repacked on-the-fly.
456
This means that when the source is fully packed, there is minimal
457
overhead during the fetch, but if the source is poorly packed the result
458
is a fairly well packed repository (not as good as 'bzr pack' but
459
good-enough.) (Robert Collins, John Arbash Meinel, #402652)
461
* Fix a potential segmentation fault when doing 'log' of a branch that had
462
ghosts in its mainline. (Evaluating None as a tuple is bad.)
463
(John Arbash Meinel, #419241)
465
* ``groupcompress`` sort order is now more stable, rather than relying on
466
``topo_sort`` ordering. The implementation is now
467
``KnownGraph.gc_sort``. (John Arbash Meinel)
469
* Local data conversion will generate correct deltas. This is a critical
470
bugfix vs 2.0rc1, and all 2.0rc1 users should upgrade to 2.0rc2 before
471
converting repositories. (Robert Collins, #422849)
473
* Network streams now decode adjacent records of the same type into a
474
single stream, reducing layering churn. (Robert Collins)
476
* Prevent some kinds of incomplete data from being committed to a 2a
477
repository, such as revisions without inventories, a missing chk_bytes
478
record for an inventory, or a missing text referenced by an inventory.
479
(Andrew Bennetts, #423506, #406687)
484
* Fix assertion error about "_remember_remote_is_before" when pushing to
486
(Andrew Bennetts, #418931)
488
* Help on hooks no longer says 'Not deprecated' for hooks that are
489
currently supported. (Ian Clatworthy, #422415)
491
* PDF and CHM (Windows HtmlHelp) formats are now supported for the
492
user documentation. The HTML documentation is better broken up into
493
topics. (Ian Clatworthy)
495
* The developer and foreign language documents are now separated
496
out so that searching in the HTML and CHM files produces more
497
useful results. (Ian Clatworthy)
499
* The main table of contents now provides links to the new Migration Docs
500
and Plugins Guide. (Ian Clatworthy)
506
:Codename: no worries
507
:2.0.0rc1: 2009-08-26
512
* The default format for bzr is now ``2a``. This format brings many
513
significant performance and size improvements. bzr can pull from
514
any existing repository into a ``2a`` one, but can only transfer
515
from ``2a`` into ``rich-root`` repositories. The Upgrade guide
516
has more information about this change. (Robert Collins)
518
* On Windows auto-detection of Putty's plink.exe is disabled.
519
Default SSH client for Windows is paramiko. User still can force
520
usage of plink if explicitly set environment variable BZR_SSH=plink.
521
(#414743, Alexander Belchenko)
526
* ``bzr branch --switch`` can now switch the checkout in the current directory
527
to the newly created branch. (Lukáš Lalinský)
532
* Further tweaks to handling of ``bzr add`` messages about ignored files.
533
(Jason Spashett, #76616)
535
* Fetches were being requested in 'groupcompress' order, but weren't
536
recombining the groups. Thus they would 'fragment' to get the correct
537
order, but not 'recombine' to actually benefit from it. Until we get
538
recombining to work, switching to 'unordered' fetches avoids the
539
fragmentation. (John Arbash Meinel, #402645)
541
* Fix a pycurl related test failure on karmic by recognizing an error
542
raised by newer versions of pycurl.
543
(Vincent Ladeuil, #306264)
545
* Fix a test failure on karmic by making a locale test more robust.
546
(Vincent Ladeuil, #413514)
548
* Fix IndexError printing CannotBindAddress errors.
549
(Martin Pool, #286871)
551
* Fix "Revision ... not present" errors when upgrading stacked branches,
552
or when doing fetches from a stacked source to a stacked target.
553
(Andrew Bennetts, #399140)
555
* ``bzr branch`` of 2a repositories over HTTP is much faster. bzr now
556
batches together small fetches from 2a repositories, rather than
557
fetching only a few hundred bytes at a time.
558
(Andrew Bennetts, #402657)
563
* A better description of the platform is shown in crash tracebacks, ``bzr
564
--version`` and ``bzr selftest``.
565
(Martin Pool, #409137)
567
* bzr can now (again) capture crash data through the apport library,
568
so that a single human-readable file can be attached to bug reports.
569
This can be disabled by using ``-Dno_apport`` on the command line, or by
570
putting ``no_apport`` into the ``debug_flags`` section of
572
(Martin Pool, Robert Collins, #389328)
574
* ``bzr push`` locally on windows will no longer give a locking error with
575
dirstate based formats. (Robert Collins)
577
* ``bzr shelve`` and ``bzr unshelve`` now work on windows.
578
(Robert Collins, #305006)
580
* Commit of specific files no longer prevents using the iter_changes
581
codepath. On 2a repositories, commit of specific files should now be as
582
fast, or slightly faster, than a full commit. (Robert Collins)
584
* The internal core code that handles specific file operations like
585
``bzr st FILENAME`` or ``bzr commit FILENAME`` has been changed to
586
include the parent directories if they have altered, and when a
587
directory stops being a directory its children are always included. This
588
fixes a number of causes for ``InconsistentDelta`` errors, and permits
589
faster commit of specific paths. (Robert Collins, #347649)
594
* New developer documentation for content filtering.
600
* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its
601
classes changed to manage lock lifetime of the trees they open in a way
602
consistent with reader-exclusive locks. (Robert Collins, #305006)
