bzr 2.0.4 (not released yet)

############################
12
:2.0.4: smooth sailing
23
* ``bzr annotate`` on another branch with ``-r branch:...`` no longer
24
fails with an ``ObjectNotLocked`` error. (Andrew Bennetts, #496590)
26
* ``bzr export dir`` now requests all file content as a record stream,
27
rather than requsting the file content one file-at-a-time. This can make
28
exporting over the network significantly faster (54min => 9min in one
29
case). (John Arbash Meinel, #343218)
31
* ``bzr serve`` no longer slowly leaks memory. The compiled
32
``bzrlib.bencode.Encoder()`` class was using ``__del__`` to cleanup and
33
free resources, and it should have been using ``__dealloc__``.
34
This will likely have an impact on any other process that is serving for
35
an extended period of time. (John Arbash Meinel, #494406)
37
* Check for SIGINT (Ctrl-C) and other signals immediately if ``readdir``
38
returns ``EINTR`` by calling ``PyErr_CheckSignals``. This affected the
39
optional ``_readdir_pyx`` extension. (Andrew Bennetts, #495023)
41
* Give a clearer message if the lockdir disappears after being apparently
42
successfully taken. (Martin Pool, #498378)
44
* If we fail to open ``~/.bzr.log`` write a clear message to stderr rather
45
than using ``warning()``. The log file is opened before logging is set
46
up, and it leads to very confusing: 'no handlers for "bzr"' messages for
47
users, rather than something nicer.
48
(John Arbash Meinel, Barry Warsaw, #503886)
50
* The 2a format wasn't properly restarting autopacks when something
51
changed underneath it (like another autopack). Now concurrent
52
autopackers will properly succeed. (John Arbash Meinel, #495000)
54
* ``_update_current_block`` no longer suppresses exceptions, so ^C at just
55
the right time will get propagated, rather than silently failing to move
56
the block pointer. (John Arbash Meinel, Gareth White, #495023)
73
* We have a new ``test_source`` that ensures all pyrex ``cdef`` functions
74
handle exceptions somehow. (Possibly by setting ``# cannot_raise``
75
rather than an ``except ?:`` clause.) This should help prevent bugs like
76
bug #495023. (John Arbash Meinel)
82
:Codename: little italy
86
The third stable release of Bazaar has a small handful of bugfixes. As
87
expected, this has no internal or external compatibility changes versus
93
* ``bzr push --use-existing-dir`` no longer crashes if the directory
94
exists but contains an invalid ``.bzr`` directory.
95
(Andrew Bennetts, #423563)
97
* Content filters are now applied correctly after pull, merge and switch.
98
(Ian Clatworthy, #385879)
100
* Fix a potential segfault in the groupcompress hash map handling code.
101
When inserting new entries, if the final hash bucket was empty, we could
102
end up trying to access if ``(last_entry+1)->ptr == NULL``.
103
(John Arbash Meinel, #490228)
105
* Improve "Binary files differ" hunk handling. (Aaron Bentley, #436325)
111
:Codename: after the scare
114
The second in our "let's keep the stable bugfixes flowing" series. As
115
expected this has a few (~9) bugfixes relative to 2.0.1, and no major api
121
* Avoid "NoneType has no attribute st_mode" error when files disappear
122
from a directory while it's being read. (Martin Pool, #446033)
124
* Content filters are now applied correctly after revert.
127
* Diff parsing handles "Binary files differ" hunks. (Aaron Bentley, #436325)
129
* Fetching from stacked pre-2a repository via a smart server no longer
130
fails intermittently with "second push failed to complete".
131
(Andrew Bennetts, #437626)
133
* Fix typos left after test_selftest refactoring.
134
(Vincent Ladeuil, Matt Nordhoff, #461149)
136
* Fixed ``ObjectNotLocked`` errors during ``bzr log -r NNN somefile``.
137
(Andrew Bennetts, #445171)
139
* PreviewTree file names are not limited by the encoding of the temp
140
directory's filesystem. (Aaron Bentley, #436794)
145
* ``bzr log`` now read-locks branches exactly once, so makes better use of
146
data caches. (Andrew Bennetts)
151
* Filtered views user documentation upgraded to refer to format 2a
152
instead of pre-2.0 formats. (Ian Clatworthy)
158
:Codename: Stability First
161
The first of our new ongoing bugfix-only stable releases has arrived. It
162
includes a collection of 12 bugfixes applied to bzr 2.0.0, but does not
163
include any of the feature development in the 2.1.0 series.
169
* ``bzr add`` in a tree that has files with ``\r`` or ``\n`` in the
170
filename will issue a warning and skip over those files.
171
(Robert Collins, #3918)
173
* bzr will attempt to authenticate with SSH servers that support
174
``keyboard-interactive`` auth but not ``password`` auth when using
175
Paramiko. (Andrew Bennetts, #433846)
177
* Fixed fetches from a stacked branch on a smart server that were failing
178
with some combinations of remote and local formats. This was causing
179
"unknown object type identifier 60" errors. (Andrew Bennetts, #427736)
181
* Fixed ``ObjectNotLocked`` errors when doing some log and diff operations
182
on branches via a smart server. (Andrew Bennetts, #389413)
184
* Handle things like ``bzr add foo`` and ``bzr rm foo`` when the tree is
185
at the root of a drive. ``osutils._cicp_canonical_relpath`` always
186
assumed that ``abspath()`` returned a path that did not have a trailing
187
``/``, but that is not true when working at the root of the filesystem.
188
(John Arbash Meinel, Jason Spashett, #322807)
190
* Hide deprecation warnings for 'final' releases for python2.6.
191
(John Arbash Meinel, #440062)
193
* Improve the time for ``bzr log DIR`` for 2a format repositories.
194
We had been using the same code path as for <2a formats, which required
195
iterating over all objects in all revisions.
196
(John Arbash Meinel, #374730)
198
* Make sure that we unlock the tree if we fail to create a TreeTransform
199
object when doing a merge, and there is limbo, or pending-deletions
200
directory. (Gary van der Merwe, #427773)
202
* Occasional IndexError on renamed files have been fixed. Operations that
203
set a full inventory in the working tree will now go via the
204
apply_inventory_delta code path which is simpler and easier to
205
understand than dirstates set_state_from_inventory method. This may
206
have a small performance impact on operations built on _write_inventory,
207
but such operations are already doing full tree scans, so no radical
208
performance change should be observed. (Robert Collins, #403322)
210
* Retrieving file text or mtime from a _PreviewTree has good performance when
211
there are many changes. (Aaron Bentley)
213
* The CHK index pages now use an unlimited cache size. With a limited
214
cache and a large project, the random access of chk pages could cause us
215
to download the entire cix file many times.
216
(John Arbash Meinel, #402623)
218
* When a file kind becomes unversionable after being added, a sensible
219
error will be shown instead of a traceback. (Robert Collins, #438569)
224
* Improved README. (Ian Clatworthy)
226
* Improved upgrade documentation for Launchpad branches.
234
:Codename: Instant Karma
236
This release of Bazaar makes the 2a (previously 'brisbane-core') format
237
the default when new branches or repositories are created. This format is
238
substantially smaller and faster for many operations. Most of the work in
239
this release focuses on bug fixes and stabilization, covering both 2a and
240
previous formats. (See the Upgrade Guide for information on migrating
243
This release also improves the documentation content and presentation,
244
including adding Windows HtmlHelp manuals.
246
The Bazaar team decided that 2.0 will be a long-term supported release,
247
with bugfix-only 2.0.x releases based on it, continuing for at least six
248
months or until the following stable release.
250
Changes from 2.0.0rc2 to final
251
******************************
253
* Officially branded as 2.0.0 rather than 2.0 to clarify between things
254
that "want to happen on the 2.0.x stable series" versus things that want
255
to "land in 2.0.0". (Changes how bzrlib._format_version_tuple() handles
256
micro = 0.) (John Arbash Meinel)
261
:2.0.0rc2: 2009-09-10
266
* Added post_commit hook for mutable trees. This allows the keywords
267
plugin to expand keywords on files changed by the commit.
268
(Ian Clatworthy, #408841)
273
* Bazaar's native protocol code now correctly handles EINTR, which most
274
noticeably occurs if you break in to the debugger while connected to a
275
bzr+ssh server. You can now can continue from the debugger (by typing
276
'c') and the process continues. However, note that pressing C-\ in the
277
shell may still kill the SSH process, which is bug 162509, so you must
278
sent a signal to the bzr process specifically, for example by typing
279
``kill -QUIT PID`` in another shell. (Martin Pool, #341535)
281
* ``bzr check`` in pack-0.92, 1.6 and 1.9 format repositories will no
282
longer report incorrect errors about ``Missing inventory ('TREE_ROOT', ...)``
283
(Robert Collins, #416732)
285
* ``bzr info -v`` on a 2a format still claimed that it was a "Development
286
format" (John Arbash Meinel, #424392)
288
* ``bzr log stacked-branch`` shows the full log including
289
revisions that are in the fallback repository. (Regressed in 2.0rc1).
290
(John Arbash Meinel, #419241)
292
* Clearer message when Bazaar runs out of memory, instead of a ``MemoryError``
293
traceback. (Martin Pool, #109115)
295
* Conversion to 2a will create a single pack for all the new revisions (as
296
long as it ran without interruption). This improves both ``bzr upgrade``
297
and ``bzr pull`` or ``bzr merge`` from local branches in older formats.
298
The autopack logic that occurs every 100 revisions during local
299
conversions was not returning that pack's identifier, which resulted in
300
the partial packs created during the conversion not being consolidated
301
at the end of the conversion process. (Robert Collins, #423818)
303
* Fetches from 2a to 2a are now again requested in 'groupcompress' order.
304
Groups that are seen as 'underutilized' will be repacked on-the-fly.
305
This means that when the source is fully packed, there is minimal
306
overhead during the fetch, but if the source is poorly packed the result
307
is a fairly well packed repository (not as good as 'bzr pack' but
308
good-enough.) (Robert Collins, John Arbash Meinel, #402652)
310
* Fix a potential segmentation fault when doing 'log' of a branch that had
311
ghosts in its mainline. (Evaluating None as a tuple is bad.)
312
(John Arbash Meinel, #419241)
314
* Fix a segmentation fault when computing the ``merge_sort`` of a graph
315
that has a ghost in the mainline ancestry.
316
(John Arbash Meinel, #419241)
318
* ``groupcompress`` sort order is now more stable, rather than relying on
319
``topo_sort`` ordering. The implementation is now
320
``KnownGraph.gc_sort``. (John Arbash Meinel)
322
* Local data conversion will generate correct deltas. This is a critical
323
bugfix vs 2.0rc1, and all 2.0rc1 users should upgrade to 2.0rc2 before
324
converting repositories. (Robert Collins, #422849)
326
* Network streams now decode adjacent records of the same type into a
327
single stream, reducing layering churn. (Robert Collins)
329
* Prevent some kinds of incomplete data from being committed to a 2a
330
repository, such as revisions without inventories, a missing chk_bytes
331
record for an inventory, or a missing text referenced by an inventory.
332
(Andrew Bennetts, #423506, #406687)
337
* Fix assertion error about "_remember_remote_is_before" when pushing to
339
(Andrew Bennetts, #418931)
341
* Help on hooks no longer says 'Not deprecated' for hooks that are
342
currently supported. (Ian Clatworthy, #422415)
344
* PDF and CHM (Windows HtmlHelp) formats are now supported for the
345
user documentation. The HTML documentation is better broken up into
346
topics. (Ian Clatworthy)
348
* The developer and foreign language documents are now separated
349
out so that searching in the HTML and CHM files produces more
350
useful results. (Ian Clatworthy)
352
* The main table of contents now provides links to the new Migration Docs
353
and Plugins Guide. (Ian Clatworthy)
359
:Codename: no worries
360
:2.0.0rc1: 2009-08-26
365
* The default format for bzr is now ``2a``. This format brings many
366
significant performance and size improvements. bzr can pull from
367
any existing repository into a ``2a`` one, but can only transfer
368
from ``2a`` into ``rich-root`` repositories. The Upgrade guide
369
has more information about this change. (Robert Collins)
371
* On Windows auto-detection of Putty's plink.exe is disabled.
372
Default SSH client for Windows is paramiko. User still can force
373
usage of plink if explicitly set environment variable BZR_SSH=plink.
374
(#414743, Alexander Belchenko)
379
* ``bzr branch --switch`` can now switch the checkout in the current directory
380
to the newly created branch. (Lukáš Lalinský)
385
* Fetches were being requested in 'groupcompress' order, but weren't
386
recombining the groups. Thus they would 'fragment' to get the correct
387
order, but not 'recombine' to actually benefit from it. Until we get
388
recombining to work, switching to 'unordered' fetches avoids the
389
fragmentation. (John Arbash Meinel, #402645)
391
* Fix a pycurl related test failure on karmic by recognizing an error
392
raised by newer versions of pycurl.
393
(Vincent Ladeuil, #306264)
395
* Fix a test failure on karmic by making a locale test more robust.
396
(Vincent Ladeuil, #413514)
398
* Fix IndexError printing CannotBindAddress errors.
399
(Martin Pool, #286871)
401
* Fix "Revision ... not present" errors when upgrading stacked branches,
402
or when doing fetches from a stacked source to a stacked target.
403
(Andrew Bennetts, #399140)
405
* ``bzr branch`` of 2a repositories over HTTP is much faster. bzr now
406
batches together small fetches from 2a repositories, rather than
407
fetching only a few hundred bytes at a time.
408
(Andrew Bennetts, #402657)
413
* A better description of the platform is shown in crash tracebacks, ``bzr
414
--version`` and ``bzr selftest``.
415
(Martin Pool, #409137)
417
* bzr can now (again) capture crash data through the apport library,
418
so that a single human-readable file can be attached to bug reports.
419
This can be disabled by using ``-Dno_apport`` on the command line, or by
420
putting ``no_apport`` into the ``debug_flags`` section of
422
(Martin Pool, Robert Collins, #389328)
424
* ``bzr push`` locally on windows will no longer give a locking error with
425
dirstate based formats. (Robert Collins)
427
* ``bzr shelve`` and ``bzr unshelve`` now work on windows.
428
(Robert Collins, #305006)
430
* Commit of specific files no longer prevents using the the iter_changes
431
codepath. On 2a repositories, commit of specific files should now be as
432
fast, or slightly faster, than a full commit. (Robert Collins)
434
* The internal core code that handles specific file operations like
435
``bzr st FILENAME`` or ``bzr commit FILENAME`` has been changed to
436
include the parent directories if they have altered, and when a
437
directory stops being a directory its children are always included. This
438
fixes a number of causes for ``InconsistentDelta`` errors, and permits
439
faster commit of specific paths. (Robert Collins, #347649)
444
* New developer documentation for content filtering.
450
* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its
451
classes changed to manage lock lifetime of the trees they open in a way
452
consistent with reader-exclusive locks. (Robert Collins, #305006)
463
:Codename: nein nein nein!
466
This release fixes two small but worthwhile bugs relevant to users on
467
Microsoft Windows: some commands that failed on with locking errors will
468
now work, and a bug that caused poor performance after committing a file
469
with line-ending conversion has now been fixed. It also fixes a bug in
470
pushing to older servers.
475
* Fixed a problem where using content filtering and especially end-of-line
476
conversion will commit too many copies a file.
477
(Martin Pool, #415508)
479
* Fix assertion error about ``_remember_remote_is_before`` in
480
``set_tags_bytes`` when pushing to older smart servers.
481
(Andrew Bennetts, Alexander Belchenko, #418931)
486
* ``bzr push`` locally on Windows will no longer give a locking error with
487
dirstate based formats. (Robert Collins)
489
* ``bzr shelve`` and ``bzr unshelve`` now work on Windows.
490
(Robert Collins, #305006)
495
* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its
496
classes changed to manage lock lifetime of the trees they open in a way
497
consistent with reader-exclusive locks. (Robert Collins, #305006)
499
* ``Tree.path_content_summary`` may return a size of None, when called on
500
a tree with content filtering where the size of the canonical form
501
cannot be cheaply determined. (Martin Pool)
510
* Committing directly to a stacked branch from a lightweight checkout will
511
no longer work. In previous versions this would appear to work but would
512
generate repositories with insufficient data to create deltas, leading
513
to later errors when branching or reading from the repository.
514
(Robert Collins, bug #375013)
522
* Fetching from 2a branches from a version-2 bzr protocol would fail to
523
copy the internal inventory pages from the CHK store. This cannot happen
524
in normal use as all 2a compatible clients and servers support the
525
version-3 protocol, but it does cause test suite failures when testing
526
downlevel protocol behaviour. (Robert Collins)
528
* Fix a test failure on karmic by making a locale test more robust.
529
(Vincent Ladeuil, #413514)
531
* Fixed "Pack ... already exists" error when running ``bzr pack`` on a
532
fully packed 2a repository. (Andrew Bennetts, #382463)
534
* Further tweaks to handling of ``bzr add`` messages about ignored files.
535
(Jason Spashett, #76616)
537
* Properly handle fetching into a stacked branch while converting the
538
data, especially when there are also ghosts. The code was filling in
539
parent inventories incorrectly, and also not handling when one of the
540
parents was a ghost. (John Arbash Meinel, #402778, #412198)
542
* ``RemoteStreamSource.get_stream_for_missing_keys`` will fetch CHK
543
inventory pages when appropriate (by falling back to the vfs stream
544
source). (Andrew Bennetts, #406686)
546
* StreamSource generates rich roots from non-rich root sources correctly
547
now. (Andrew Bennetts, #368921)
549
* When deciding whether a repository was compatible for upgrading or
550
fetching, we previously incorrectly checked the default repository
551
format for the bzrdir format, rather than the format that was actually
552
present on disk. (Martin Pool, #408824)
557
* A better description of the platform is shown in crash tracebacks, ``bzr
558
--version`` and ``bzr selftest``.
559
(Martin Pool, #409137)
561
* Cross-format fetches (such as between 1.9-rich-root and 2a) via the
562
smart server are more efficient now. They send inventory deltas rather
563
than full inventories. The smart server has two new requests,
564
``Repository.get_stream_1.19`` and ``Repository.insert_stream_1.19`` to
565
support this. (Andrew Bennetts, #374738, #385826)
567
* Extracting the full ancestry and computing the ``merge_sort`` is now
568
significantly faster. This effects things like ``bzr log -n0``. (For
569
example, ``bzr log -r -10..-1 -n0 bzr.dev`` is 2.5s down to 1.0s.
581
* ``-Dstrict_locks`` can now be used to check that read and write locks
582
are treated properly w.r.t. exclusivity. (We don't try to take an OS
583
read lock on a file that we already have an OS write lock on.) This is
584
now set by default for all tests, if you have a test which cannot be
585
fixed, you can use ``self.thisFailsStrictLockCheck()`` as a
586
compatibility knob. (John Arbash Meinel)
588
* InterDifferingSerializer is now only used locally. Other fetches that
589
would have used InterDifferingSerializer now use the more network
590
friendly StreamSource, which now automatically does the same
591
transformations as InterDifferingSerializer. (Andrew Bennetts)
593
* ``KnownGraph`` now has a ``.topo_sort`` and ``.merge_sort`` member which
594
are implemented in pyrex and significantly faster. This is exposed along
595
with ``CombinedGraphIndex.find_ancestry()`` as
596
``VersionedFiles.get_known_graph_ancestry(keys)``.
599
* RemoteBranch.open now honours ignore_fallbacks correctly on bzr-v2
600
protocols. (Robert Collins)
602
* The index code now has some specialized routines to extract the full
603
ancestry of a key in a more efficient manner.
604
``CombinedGraphIndex.find_ancestry()``. (Time to get ancestry for
605
bzr.dev drops from 1.5s down to 300ms. For OOo from 33s => 10.5s) (John
611
* Install the test ssl certificate and key so that installed bzr
612
can run the https tests. (Denys Duchier, #392401)
618
:Codename: little traveller
622
This release of Bazaar marches on towards the 2.0 release in which the 2a
623
'brisbane-core' format becomes generally recommended. Most of the work in
624
this release now focusses on bug fixes and stabilization, covering both 2a
625
and previous formats. There is a new text-mode interactive merge feature,
626
a new guide to migration to 2a format in the user documentation, and
627
pushing branches to a smart server is now much faster.
629
The Bazaar team decided that 2.0 will be a long-term supported release,
630
with bugfix-only releases based on it continuing for at least six months
631
or until the following stable release.
633
There are no changes from 1.18rc1 to 1.18.
638
* ``bzr merge --interactive`` applies a user-selected portion of the
639
merge. The UI is similar to ``shelve``. (Aaron Bentley)
641
* ``bzr reconfigure`` now takes options ``--stacked-on URL`` and
642
``--unstacked`` to change stacking of a branch.
643
(Martin Pool, #391411)
648
* Annotating on a stacked branch will now succeed in simple scenarios.
649
There are still some complex scenarios where it will fail (bug #399884)
650
(John Arbash Meinel, #393366)
652
* A progress bar is no longer left dangling when ``bzr selftest``
653
completes, and the progress bar updates with zero latency so the
654
displayed test name is always the one that's actually running.
655
(Martin Pool, #123688)
657
* Authenticating against an ssh server now uses ``auth_none`` to determine
658
if password authentication is even supported. This fixes a bug where
659
users would be prompted for a launchpad password, even though launchpad
660
only supports publickey authentication. (John Arbash Meinel, #375867)
662
* BranchBuilder now accepts timezone to avoid test failures in countries far
663
from GMT. (Vincent Ladeuil, #397716)
665
* ``bzr commit`` no longer saves the unversioning of missing files until
666
the commit has completed on the branch. This means that aborting a
667
commit that found a missing file will leave the tree unedited.
668
(Robert Collins, #282402)
670
* ``bzr mv`` no longer takes out branch locks, which allows it to work
671
when the branch is readonly. (Robert Collins, #216541)
673
* ``bzr revert .`` no longer generates an InconsistentDelta error when
674
there are missing subtrees. (Robert Collins, #367632)
676
* ``bzr send`` now generates valid bundles with ``--2a`` formats. However,
677
do to internal changes necessary to support this, older clients will
678
fail when trying to insert them. For newer clients, the bundle can be
679
used to apply the changes to any rich-root compatible format.
680
(John Arbash Meinel, #393349)
682
* Cope with FTP servers that don't support restart/append by falling back
683
to reading and then rewriting the whole file, such as TahoeLAFS. (This
684
fallback may be slow for some access patterns.) (Nils Durner, #294709)
686
* Encode the paths in ``mbcs`` encoding on Windows when spawning an
687
external diff client. This at least allows supporting filenames that are
688
not ascii, but are present in the current locale. Ideally we would be
689
able to pass the Unicode path, but that would be client dependent.
690
(John Arbash Meinel, #382709)
692
* Fix a compile bug on Solaris having to do with const and
693
pointer-to-pointers. (John Arbash Meinel, #408441)
695
* Fixed a NameError that occurs when merging or pulling from a URL that
696
causes a redirection loop when bzr tries to read a URL as a bundle.
697
(Andrew Bennetts, #400847)
699
* Fix ``AttributeError: 'TestUIFactory' object has no attribute 'tick'``
700
running send and similar commands on 2a formats.
701
(Martin Pool, #408201)
703
* Fix crash in some invocations of ``bzr status`` in format 2a.
704
(Martin Pool, #403523)
706
* Fixed export to existing directory: if directory is empty then export
707
will succeed, otherwise it fails with error.
708
(Alexander Belchenko, #406174)
710
* Fixed spurious "Source branch does not support stacking" warning when
711
pushing. (Andrew Bennetts, #388908)
713
* Fixed spurious transport activity indicator appearing while tests are
714
running. (Martin Pool, #343532)
716
* Merge now correctly handles empty right-hand revision specs.
717
(Aaron Bentley, #333961)
719
* Renames to lexographically lower basenames in trees that have never been
720
committed to will no longer corrupt the dirstate. This was caused by an
721
bug in the dirstate update_minimal method. (Robert Collins, #395556)
723
* Requests for unknown methods no longer cause the smart server to log
724
lots of backtraces about ``UnknownSmartMethod``, ``do_chunk`` or
725
``do_end``. (Andrew Bennetts, #338561)
727
* Shelve will not shelve the initial add of the tree root. (Aaron Bentley)
729
* Streaming from bzr servers where there is a chain of stacked branches
730
(A stacked on B stacked on C) will now work. (Robert Collins, #406597)
732
* The environment variable ``BZR_PROGRESS_BAR`` set to either ``text`` or ``none``
733
always forces progress bars either on or off respectively. Otherwise,
734
they're turned on if ``TERM`` is not ``dumb`` and stderr is a terminal.
735
bzr always uses the 'text' user interface when run as a command, so
736
``BZR_USE_TEXT_UI`` is no longer needed.
737
(Martin Pool, #339385, #387717)
739
* The optional ``_knit_load_data_pyx`` C extension was never being
740
imported. This caused significant slowdowns when reading data from
741
repositories. (Andrew Bennetts, #405653)
743
* The ``--hardlink`` option to ``branch`` and ``checkout`` is not
744
supported at the moment on workingtree formats that can do content
745
filtering. (See <https://bugs.edge.launchpad.net/bzr/+bug/408193>.)
746
bzr now says so, rather than just ignoring the option. (Martin Pool)
748
* There was a bug in ``osutils.relpath`` that was only triggered on
749
Windows. Essentially if you were at the root of a drive, and did
750
something to a branch/repo on another drive, we would go into an
751
infinite loop while trying to find a 'relative path'.
752
(John Arbash Meinel, #394227)
754
* ``WorkingTree4.unversion`` will no longer fail to unversion ids which
755
were present in a parent tree but renamed in the working tree.
756
(Robert Collins, #187207)
761
* Can now rename/move files even if they have been removed from the inventory.
764
* Pushing branches with tags via ``bzr://`` and ``bzr+ssh://`` is much
765
faster, using a new ``Branch.set_tags_bytes`` smart server verb rather
766
than VFS methods. For example, pushes of small branches with tags take
767
11 rather than 18 smart server requests. (Andrew Bennetts, #398608)
769
* Sending Ctrl-Break on Windows will now drop you into the debugger, in
770
the same way that sending Ctrl-\\ does on other platforms.
776
* Added Bazaar 2.0 Upgrade Guide. (Ian Clatworthy)
781
* ``CLIUIFactory`` is deprecated; use ``TextUIFactory`` instead if you
782
need to subclass or create a specific class, or better yet the existing
783
``make_ui_for_terminal``. ``SilentUIFactory`` is clarified to do no
784
user interaction at all, rather than trying to read from stdin but not
785
writing any output, which would be strange if reading prompts or
786
passwords. (Martin Pool)
788
* New TransformPreview.commit() allows committing without a working tree.
791
* ``pb`` parameter to ``TextTestResult`` is deprecated and ignored.
794
* ProgressTasks now prefer to talk direct to their ProgressView not to the
798
* ``WorkingTree._check`` now requires a references dict with keys matching
799
those returned by ``WorkingTree._get_check_refs``. (Robert Collins)
804
* ``CHKInventory.path2id`` uses the parent_id to basename hash to avoid
805
reading the entries along the path, reducing work to lookup ids from
806
paths. (Robert Collins)
808
* ``CHKMap.apply_delta`` now raises ``InconsistentDelta`` if a delta adds
809
as new a key which was already mapped. (Robert Collins)
811
* Inventory delta application catches more cases of corruption and can
812
prevent corrupt deltas from affecting consistency of data structures on
813
disk. (Robert Collins)
815
* --subunit support now adds timestamps if the subunit version supports
818
* The Windows all-in-one installer now bundles the PyQt image format
819
plugins, which allows previewing more images as part of 'qdiff'.
820
(Alexander Belchenko)
826
* Merge directive cherrypick tests must use the same root id.
827
(Martin Pool, #409684)
829
* Spurious failure in ``check`` tests on rich-root formats fixed.
830
(Martin Pool, #408199)
832
* The ``bzrlib.tests.TextTestRunner`` will no longer call
833
``countTestsCases`` on the test being run. Progress information is
834
instead handled by having the test passed in call ``result.progress``
835
before running its contents. This improves the behaviour when using
836
``TextTestRunner`` with test suites that don't support
837
``countTestsCases``. (Robert Collins)
842
:Codename: so-late-its-brunch
847
Bazaar continues to blaze a straight and shining path to the 2.0 release and
848
the elevation of the ``2a`` beta format to the full glory of "supported and
851
Highlights in this release include greatly reduced memory consumption during
852
commits, faster ``ls``, faster ``annotate``, faster network operations if
853
you're specifying a revision number and the final destruction of those
854
annoying progress bar artifacts.
857
Changes from 1.17rc1 to 1.17final
858
*********************************
860
* Change an extension to call the python ``frozenset()`` rather than the C
861
api ``PyFrozenSet_New``. It turns out that python2.4 did not expose the
862
C api. (John Arbash Meinel, #399366)
864
* Fixes for the Makefile and the rename of ``generate_docs.py`` to
865
``tools/generate_docs.py`` to allow everything to be built on Windows.
866
(John Arbash Meinel, #399356)
868
* ``bzr serve`` once again applies a ``ChrootServer`` to the given
869
directory before serving it. (Andrew Bennetts, #400535)
875
* ``bzr register-branch`` from the Launchpad plugin now refers to "project"
876
instead of "product" which is the correct Launchpad terminology. The
877
--product option is deprecated and users should switch to using --project.
878
(Neil Martinsen-Burrell, #238764)
884
* ``bzr push`` now aborts if uncommitted changes (including pending merges)
885
are present in the working tree (if one is present) and no revision is
886
specified. The configuration option ``push_strict`` can be used to set the
887
default for this behavior. (Vincent Ladeuil, #284038, #322808, #65286)
889
* ``bzr revno`` and ``bzr revision-info`` now have a ``--tree`` option to
890
show revision info for the working tree instead of the branch.
891
(Matthew Fuller, John Arbash Meinel)
893
* ``bzr send`` now aborts if uncommitted changes (including pending merges)
894
are present in the working tree and no revision is specified. The
895
configuration option ``send_strict`` can be used to set the default for this
897
(Vincent Ladeuil, #206577)
899
* ``bzr switch --create-branch/-b`` can now be used to create and switch
900
to a new branch. Supplying a name without a ``/`` will create the branch
901
relative to the existing branch. (similar to how ``bzr switch name``
902
works when the branch already exists.) (John Arbash Meinel)
908
* Accept uppercase "Y/N" to prompts such as from break lock.
909
(#335182, Tim Powell, Martin Pool)
911
* Add documentation about diverged branches and how to fix them in the
912
centralized workflow with local commits. Mention ``bzr help
913
diverged-branches`` when a push fails because the branches have
914
diverged. (Neil Martinsen-Burrell, #269477)
916
* Annotate would sometimes 'latch on' to trivial lines, causing important
917
lines to be incorrectly annotated. (John Arbash Meinel, #387952)
919
* Automatic format upgrades triggered by default stacking policies on a
920
1.16rc1 (or later) smart server work again.
921
(Andrew Bennetts, #388675)
923
* Avoid progress bar artifacts being left behind on the screen.
924
(Martin Pool, #321935)
926
* Better message in ``bzr split`` error suggesting a rich root format.
927
(Neil Martinsen-Burrell, #220067)
929
* ``Branch.set_append_revisions_only`` now works with branches on a smart
930
server. (Andrew Bennetts, #365865)
932
* By default, ``bzr branch`` will fail if the target directory exists, but
933
does not already have a control directory. The flag ``--use-existing-dir``
934
will allow operation to proceed. (Alexander Belchenko, #307554)
936
* ``bzr ls DIR --from-root`` now shows only things in DIR, not everything.
939
* Fetch between repositories does not error if they have inconsistent data
940
that should be irrelevant to the fetch operation. (Aaron Bentley)
942
* Fix ``AttributeError`` exception when reconfiguring lightweight checkout
943
of a remote repository.
944
(Jelmer Vernooij, #332194)
946
* Fix bug in decoding v3 smart server messages when receiving multiple
947
lots of excess bytes after an end-of-message.
950
* Force deletion of readonly files during merge, update and other tree
952
(Craig Hewetson, Martin Pool, #218206)
954
* Force socket shutdown in threaded http test servers to avoid client hangs
955
(pycurl). (Vincent Ladeuil, #383920).
957
* ``LRUCache`` will maintain the linked list pointers even if a nodes
958
cleanup function raises an exception. (John Arbash Meinel, #396838)
960
* Progress bars are now suppressed again when the environment variable
961
``BZR_PROGRESS_BAR`` is set to ``none``.
962
(Martin Pool, #339385)
964
* Reduced memory consumption during ``bzr commit`` of large files. For
965
pre 2a formats, should be down to ~3x the size of a file.
966
For ``--2a`` format repositories, it is down to the size of the file
967
content plus the size of the compressed text. Related to bug #109114.
970
* Set hidden attribute on .bzr directory below unicode path should never
971
fail with error. The operation should succeed even if bzr unable to set
972
the attribute. (Alexander Belchenko, related to bug #335362).
974
* Stacking will no longer accept requests to stack on the same
975
branch/repository. Existing branches that incorrectly reference the same
976
repository in a stacking configuration will now raise
977
UnstackableLocationError when the branch is opened. This can be fixed by
978
removing the stacking location inside ``.bzr/branch``.
979
(Robert Collins, #376243)
981
* The ``log+`` decorator, useful in debugging or profiling, could cause
982
"AttributeError: 'list' object has no attribute 'next'". This is now
983
fixed. The log decorator no longer shows the elapsed time or transfer
984
rate because they're available in the log prefixes and the transport
985
activity display respectively.
986
(Martin Pool, #340347)
988
* Unshelve works correctly when multiple zero-length files are present on
989
the shelf. (Aaron Bentley, #363444)
991
* Progress bars no longer show the network transport scheme or direction.
994
* launchpad-login now respects the 'verbose' option.
995
(Jonathan Lange, #217031)
1001
* ``bzrlib.user_encoding`` is now officially deprecated. It is not
1002
possible to write a deprecation wrapper, but the variable will be
1003
removed in the near future. Use ``bzrlib.osutils.get_user_encoding()``
1004
instead. (Alexander Belchenko)
1006
* Command lookup has had hooks added. ``bzrlib.Command.hooks`` has
1007
three new hook points: ``get_command``, ``get_missing_command`` and
1008
``list_commands``, which allow just-in-time command name provision
1009
rather than requiring all command names be known a-priori.
1012
* ``get_app_path`` from win32utils.py now supports REG_EXPAND_SZ data type
1013
and can read path to wordpad.exe. (Alexander Belchenko, #392046)
1015
* ``graph.KnownGraph`` has been added. This is a class that can give
1016
answers to ``heads()`` very quickly. However, it has the assumption that
1017
the whole graph has already been loaded. This is true during
1018
``annotate`` so it is used there with good success (as much as 2x faster
1019
for files with long ancestry and 'cherrypicked' changes.)
1020
(John Arbash Meinel, Vincent Ladeuil)
1022
* OS file locks are now taken out using ``CreateFile`` rather than
1023
``LockFileEx`` on Windows. The locking remains exclusive with
1024
``LockFileEx`` but now it also works on older versions of Windows (such
1025
as Win98). (Martin <gzlist>)
1027
* pack <=> pack fetching is now done via a ``PackStreamSource`` rather
1028
than the ``Packer`` code. The user visible change is that we now
1029
properly fetch the minimum number of texts for non-smart fetching.
1030
(John Arbash Meinel)
1033
* ``VersionedFiles._add_text`` is a new api that lets us insert text into
1034
the repository as a single string, rather than a list of lines. This can
1035
improve memory overhead and performance of committing large files.
1036
(Currently a private api, used only by commit). (John Arbash Meinel)
1042
* ``bzr annotate`` can now be significantly faster. The time for
1043
``bzr annotate NEWS`` is down to 7s from 22s in 1.16. Files with long
1044
histories and lots of 'duplicate insertions' will be improved more than
1045
others. (John Arbash Meinel, Vincent Ladeuil)
1047
* ``bzr ls`` is now faster. On OpenOffice.org, the time drops from 2.4
1048
to 1.1 seconds. The improvement for ``bzr ls -r-1`` is more
1049
substantial dropping from 54.3 to 1.1 seconds. (Ian Clatworthy)
1051
* Improve "Path(s) are not versioned" error reporting for some commands.
1054
* Initial commit performance in ``--2a`` repositories has been improved by
1055
making it cheaper to build the initial CHKMap. (John Arbash Meinel)
1057
* Resolving a revno to a revision id on a branch accessed via ``bzr://``
1058
or ``bzr+ssh://`` is now much faster and involves no VFS operations.
1059
This speeds up commands like ``bzr pull -r 123``. (Andrew Bennetts)
1061
* ``revision-info`` now properly aligns the revnos/revids in the output
1062
and doesn't traceback when given revisions not in the current branch.
1063
Performance is also significantly improved when requesting multiple revs
1064
at once. (Matthew Fuller, John Arbash Meinel)
1066
* Tildes are no longer escaped by Transports. (Andy Kilner)
1072
* Avoid bad text wrapping in generated documentation. Slightly better
1073
formatting in the user reference.
1074
(Martin Pool, #249908)
1076
* Minor clarifications to the help for End-Of-Line conversions.
1082
* Removed overspecific error class ``InvalidProgressBarType``.
1085
* The method ``ProgressView._show_transport_activity`` is now
1086
``show_transport_activity`` because it's part of the contract between
1087
this class and the UI. (Martin Pool)
1093
:Released: 2009-06-26
1095
End user testing of the 2a format revealed two serious bugs. The first,
1096
#365615, caused bzr to raise AbsentContentFactory errors when autopacking.
1097
This meant that commits or pushes to 2a-format repositories failed
1100
The second bug, #390563, caused the smart server to raise AbsentContentFactory
1101
when streaming 2a stacked 2a-format branches. This particularly affected
1102
branches stored on Launchpad in the 2a format.
1104
Both of these bugs cause command failures only, neither of them cause data
1105
corruption or data loss. And, of course, both of these bugs are now fixed.
1110
* We now properly request a more minimal set of file texts when fetching
1111
multiple revisions. (Robert Collins, John Arbash Meinel, #390563)
1113
* Repositories using CHK pages (which includes the new 2a format) will no
1114
longer error during commit or push operations when an autopack operation
1115
is triggered. (Robert Collins, #365615)
1117
* ``chk_map.iter_interesting_nodes`` now properly uses the *intersection*
1118
of referenced nodes rather than the *union* to determine what
1119
uninteresting pages we still need to look at. Prior to this,
1120
incrementally pushing to stacked branch would push the minimal data, but
1121
fetching everything would request extra texts. There are some unhandled
1122
cases wrt trees of different depths, but this fixes the common cases.
1123
(Robert Collins, John Arbash Meinel, #390563)
1125
* ``GroupCompress`` repositories now take advantage of the pack hints
1126
parameter to permit cross-format fetching to incrementally pack the
1127
converted data. (Robert Collins)
1129
* ``Repository.commit_write_group`` now returns opaque data about what
1130
was committed, for passing to the ``Repository.pack``. Repositories
1131
without atomic commits will still return None. (Robert Collins)
1133
* ``Repository.pack`` now takes an optional ``hint`` parameter
1134
which will support doing partial packs for repositories that can do
1135
that. (Robert Collins)
1137
* RepositoryFormat has a new attribute 'pack_compresses' which is True
1138
when doing a pack operation changes the compression of content in the
1139
repository. (Robert Collins)
1141
* ``StreamSink`` and ``InterDifferingSerialiser`` will call
1142
``Repository.pack`` with the hint returned by
1143
``Repository.commit_write_group`` if the formats were different and the
1144
repository can increase compression by doing a pack operation.

:Codename: yesterday-in-california
1151
:1.16rc1: 2009-06-11
1154
This version of Bazaar contains the beta release of the new ``2a`` repository
1155
format, suitable for testing by fearless, advanced users. This format or an
1156
updated version of it will become the default format in Bazaar 2.0. Please
1157
read the NEWS entry before even thinking about upgrading to the new format.
1159
Also included are speedups for many operations on huge projects, a bug fix for
1160
pushing stacked new stacked branches to smart servers and the usual bevy of
1161
bug fixes and improvements.
1164
Changes from 1.16rc1 to 1.16final
1165
*********************************
1167
* Fix the nested tree flag check so that upgrade from development formats to
1168
2a can work correctly.
1169
(Jelmer Vernooij, #388727)
1171
* Automatic format upgrades triggered by default stacking policies on a
1172
1.16rc1 (or later) smart server work again.
1173
(Andrew Bennetts, #388675)
1176
Compatibility Breaks
1177
********************
1179
* Display prompt on stderr (instead of stdout) when querying users so
1180
that the output of commands can be safely redirected.
1181
(Vincent Ladeuil, #376582)
1187
* A new repository format ``2a`` has been added. This is a beta release
1188
of the the brisbane-core (aka group-compress) project. This format now
1189
suitable for wider testing by advanced users willing to deal with some
1190
bugs. We would appreciate test reports, either positive or negative.
1191
Format 2a is substantially smaller and faster for many operations on
1192
many trees. This format or an updated version will become the default
1195
This is a rich-root format, so this repository format can be used with
1196
bzr-svn. Bazaar branches in previous non-rich-root formats can be
1197
converted (including by merge, push and pull) to format 2a, but not vice
1198
versa. We recommend upgrading previous development formats to 2a.
1200
Upgrading to this format can take considerable time because it expands
1201
and more concisely repacks the full history.
1203
If you use stacked branches, you must upgrade the stacked branches
1204
before the stacked-on branches. (See <https://bugs.launchpad.net/bugs/374735>)
1206
* ``--development7-rich-root`` is a new dev format, similar to ``--dev6``
1207
but using a Revision serializer using bencode rather than XML.
1208
(Jelmer Vernooij, John Arbash Meinel)
1210
* mail_client=claws now supports --body (and message body hooks). Also uses
1211
configured from address. (Barry Warsaw)
1217
* ``--development6-rich-root`` can now stack. (Modulo some smart-server
1218
bugs with stacking and non default formats.)
1219
(John Arbash Meinel, #373455)
1221
* ``--development6-rich-root`` delays generating a delta index for the
1222
first object inserted into a group. This has a beneficial impact on
1223
``bzr commit`` since each committed texts goes to its own group. For
1224
committing a 90MB file, it drops peak memory by about 200MB, and speeds
1225
up commit from 7s => 4s. (John Arbash Meinel)
1227
* Numerous operations are now faster for huge projects, i.e. those
1228
with a large number of files and/or a large number of revisions,
1229
particularly when the latest development format is used. These
1230
operations (and improvements on OpenOffice.org) include:
1232
* branch in a shared repository (2X faster)
1233
* branch --no-tree (100X faster)
1239
* Pyrex version of ``bencode`` support. This provides optimized support
1240
for both encoding and decoding, and is now found at ``bzrlib.bencode``.
1241
``bzrlib.utils.bencode`` is now deprecated.
1242
(Alexander Belchenko, Jelmer Vernooij, John Arbash Meinel)
1248
* Bazaar can now pass attachment files to the mutt email client.
1249
(Edwin Grubbs, #384158)
1251
* Better message in ``bzr add`` output suggesting using ``bzr ignored`` to
1252
see which files can also be added. (Jason Spashett, #76616)
1254
* ``bzr pull -r 123`` from a stacked branch on a smart server no longer fails.
1255
Also, the ``Branch.revision_history()`` API now works in the same
1256
situation. (Andrew Bennetts, #380314)
1258
* ``bzr serve`` on Windows no longer displays a traceback simply because a
1259
TCP client disconnected. (Andrew Bennetts)
1261
* Clarify the rules for locking and fallback repositories. Fix bugs in how
1262
``RemoteRepository`` was handling fallbacks along with the
1263
``_real_repository``. (Andrew Bennetts, John Arbash Meinel, #375496)
1265
* Fix a small bug with fetching revisions w/ ghosts into a new stacked
1266
branch. Not often triggered, because it required ghosts to be part of
1267
the fetched revisions, not in the stacked-on ancestry.
1268
(John Arbash Meinel)
1270
* Fix status and commit to work with content filtered trees, addressing
1271
numerous bad bugs with line-ending support. (Ian Clatworthy, #362030)
1273
* Fix problem of "directory not empty" when contending for a lock over
1274
sftp. (Martin Pool, #340352)
1276
* Fix rule handling so that eol is optional, not mandatory.
1277
(Ian Clatworthy, #379370)
1279
* Pushing a new stacked branch to a 1.15 smart server was broken due to a
1280
bug in the ``BzrDirFormat.initialize_ex`` smart verb. This is fixed in
1281
1.16, but required changes to the network protocol, so the
1282
``BzrDirFormat.initialize_ex`` verb has been removed and replaced with a
1283
corrected ``BzrDirFormat.initialize_ex_1.16`` verb. 1.15 clients will
1284
still work with a 1.16 server as they will fallback to slower (and
1286
(Jonathan Lange, Robert Collins, Andrew Bennetts, #385132)
1288
* Reconcile can now deal with text revisions that originated in revisions
1289
that are ghosts. (Jelmer Vernooij, #336749)
1291
* Support cloning of branches with ghosts in the left hand side history.
1292
(Jelmer Vernooij, #248540)
1294
* The ''bzr diff'' now catches OSError from osutils.rmtree and logs a
1295
helpful message to the trace file, unless the temp directory really was
1296
removed (which would be very strange). Since the diff operation has
1297
succeeded from the user's perspective, no output is written to stderr
1298
or stdout. (Maritza Mendez, #363837)
1300
* Translate errors received from a smart server in response to a
1301
``BzrDirFormat.initialize`` or ``BzrDirFormat.initialize_ex`` request.
1302
This was causing tracebacks even for mundane errors like
1303
``PermissionDenied``. (Andrew Bennetts, #381329)
1308
* Added directory structure and started translation of docs in Russian.
1309
(Alexey Shtokalo, Alexander Iljin, Alexander Belchenko, Dmitry Vasiliev,
1310
Volodymyr Kotulskyi)
1315
* Added osutils.parent_directories(). (Ian Clatworthy)
1317
* ``bzrlib.progress.ProgressBar``, ``ChildProgress``, ``DotsProgressBar``,
1318
``TTYProgressBar`` and ``child_progress`` are now deprecated; use
1319
``ui_factory.nested_progress_bar`` instead. (Martin Pool)
1321
* ``graph.StackedParentsProvider`` is now a public API, replacing
1322
``graph._StackedParentsProvider``. The api is now considered stable and ready
1323
for external users. (Gary van der Merwe)
1325
* ``bzrlib.user_encoding`` is deprecated in favor of
1326
``get_user_encoding``. (Alexander Belchenko)
1328
* TreeTransformBase no longer assumes that limbo is provided via disk.
1329
DiskTreeTransform now provides disk functionality. (Aaron Bentley)
1334
* Remove ``weave.py`` script for accessing internals of old weave-format
1335
repositories. (Martin Pool)
1340
* The number of cores is now correctly detected on OSX. (John Szakmeister)
1342
* The number of cores is also detected on Solaris and win32. (Vincent Ladeuil)
1344
* The number of cores is also detected on FreeBSD. (Matthew Fuller)

:1.15rc1: 2009-05-16
1353
The smart server will no longer raise 'NoSuchRevision' when streaming content
1354
with a size mismatch in a reconstructed graph search. New command ``bzr
1355
dpush``. Plugins can now define their own annotation tie-breaker when two
1356
revisions introduce the exact same line.
