A couple regressions were found in the 1.6 release. There was a
14
performance issue when using ``bzr+ssh`` to branch large repositories,
15
and some problems with stacking and ``rich-root`` capable repositories.

* Copying between ``rich-root`` and ``rich-root-pack`` (and vice
27
versa) was accidentally using the inter-model fetcher, instead of
28
recognizing that both were 'rich root' formats.

:Released: 2008-08-29
36
37
This release fixes a few regressions found in the 1.6 client. Fetching
38
changes was using an O(N^2) buffering algorithm, so for large projects it
39
would cause memory thrashing. There is also a specific problem with the
40
``--1.6-rich-root`` format, which prevented stacking on top of
41
``--rich-root-pack`` repositories, and could allow users to accidentally
42
fetch experimental data (``-subtree``) without representing it properly.
43
The ``--1.6-rich-root`` format has been deprecated and users are
44
recommended to upgrade to ``--1.6.1-rich-root`` immediately. Also we
45
re-introduced a workaround for users who have repositories with incorrect
46
nodes (not possible if you only used official releases).
47
I should also clarify that none of this is data loss level issues, but
48
still sufficient enough to warrant an updated release.
49
50
Bug Fixes
51
*********
52
53
* ``RemoteTransport.readv()`` was being inefficient about how it
54
buffered the readv data and processed it. It would keep appending to
55
the same string (causing many copies) and then pop bytes out of the
56
start of the string (causing more copies).
57
With this patch "bzr+ssh://local" can improve dramatically,
58
especially for projects with large files.
59
(John Arbash Meinel)
60
61
* Revision texts were always meant to be stored as fulltexts. There
62
was a bug in a bzr.dev version that would accidentally create deltas
63
when copying from a Pack repo to a Knit repo. This has been fixed,
64
but to support those repositories, we know always request full texts
65
for Revision texts. (John Arbash Meinel, #261339)
66
67
* The previous ``--1.6-rich-root`` format used an incorrect xml
68
serializer, which would accidentally support fetching from a
69
repository that supported subtrees, even though the local one would
70
not. We deprecated that format, and introduced a new one that uses
71
the correct serializer ``--1.6.1-rich-root``.

80
Finally, the long awaited bzr 1.6 has been released. This release includes
81
new features like Stacked Branches, improved weave merge, and an updated
82
server protocol (now on v3) which will allow for better cross version
83
compatibility. With this release we have deprecated Knit format
84
repositories, and recommend that users upgrade them, we will continue to
85
support reading and writing them for the forseeable future, but we will
86
not be tuning them for performance as pack repositories have proven to be
87
better at scaling. This will also be the first release to bundle
88
TortoiseBzr in the standalone Windows installer.

* Disable automatic detection of stacking based on a containing
100
directory of the target. It interacted badly with push, and needs a
101
bit more work to get the edges polished before it should happen
102
automatically. (John Arbash Meinel, #259275)

************
133
134
* Update the windows installer to bundle TortoiseBzr and ``qbzr``
135
into the standalone installer. This will be the first official
136
windows release that installs Tortoise by default.

Bug Fixes
140
*********
141
142
* Fix a regression in ``bzr+http`` support. There was a missing
143
function (``_read_line``) that needed to be carried over from
144
``bzr+ssh`` support. (Andrew Bennetts)
145
146
* ``GraphIndex`` objects will internally read an entire index if more
147
than 1/20th of their keyspace is requested in a single operation.
148
This largely mitigates a performance regression in ``bzr log FILE``
149
and completely corrects the performance regression in ``bzr log``.
150
The regression was caused by removing an accomodation which had been
151
supporting the index format in use. A newer index format is in
152
development which is substantially faster. (Robert Collins)

*********
165
166
* ``bzr upgrade`` on remote branches accessed via bzr:// and
167
bzr+ssh:// now works. (Andrew Bennetts)
168
169
* Change the ``get_format_description()`` strings for
170
``RepositoryFormatKnitPack5`` et al to be single line messages.
171
(Aaron Bentley)
172
173
* Fix for a regression on Win32 where we would try to call
174
``os.listdir()`` on a file and not catch the exception properly.
175
(Windows raises a different exception.) This would manifest in
176
places like ``bzr rm file`` or ``bzr switch``.
177
(Mark Hammond, John Arbash Meinel)
178
179
* ``Inventory.copy()`` was failing to set the revision property for
180
the root entry. (Jelmer Vernooij)
181
182
* sftp transport: added missing ``FileExists`` case to
183
``_translate_io_exception`` (Christophe Troestler, #123475)
184
185
* The help for ``bzr ignored`` now suggests ``bzr ls --ignored`` for
186
scripting use. (Robert Collins, #3834)
187
188
* The default ``annotate`` logic will now always assign the
189
last-modified value of a line to one of the revisions that modified
190
it, rather than a merge revision. This would happen when both sides
191
claimed to have modified the line resulting in the same text. The
192
choice is arbitrary but stable, so merges in different directions
193
will get the same results. (John Arbash Meinel, #232188)

201
This release candidate for bzr 1.6 solidifies the new branch stacking
202
feature. Bazaar now recommends that users upgrade all knit repositories,
203
because later formats are much faster. However, we plan to continue read/write and
204
upgrade support for knit repostories for the forseeable future. Several
205
other bugs and performance issues were fixed.
206
207
Changes
208
*******
209
210
* Knit format repositories are deprecated and bzr will now emit
211
warnings whenever it encounters one. Use ``bzr upgrade`` to upgrade
212
knit repositories to pack format. (Andrew Bennetts)
213
214
Improvements
215
************
216
217
* ``bzr check`` can now be told which elements at a location it should
218
check. (Daniel Watkins)
219
220
* Commit now supports ``--exclude`` (or ``-x``) to exclude some files
221
from the commit. (Robert Collins, #3117)
222
223
* Fetching data between repositories that have the same model but no
224
optimised fetcher will not reserialise all the revisions, increasing
225
performance. (Robert Collins, John Arbash Meinel)
226
227
* Give a more specific error when target branch is not reachable.
228
(James Westby)
229
230
* Implemented a custom ``walkdirs_utf8`` implementation for win32.
231
This uses a pyrex extension to get direct access to the
232
``FindFirstFileW`` style apis, rather than using ``listdir`` +
233
``lstat``. Shows a very strong improvement in commands like
234
``status`` and ``diff`` which have to iterate the working tree.
235
Anywhere from 2x-6x faster depending on the size of the tree (bigger
236
trees, bigger benefit.) (John Arbash Meinel)
237
238
* New registry for log properties handles and the method in
239
LongLogFormatter to display the custom properties returned by the
240
registered handlers. (Guillermo Gonzalez, #162469)
241
242
Bug Fixes
243
*********
244
245
* Add more tests that stacking does not create deltas spanning
246
physical repository boundaries.
247
(Martin Pool, #252428)
248
249
* Better message about incompatible repositories.
250
(Martin Pool, #206258)
251
252
* ``bzr branch --stacked`` ensures the destination branch format can
253
support stacking, even if the origin does not.
254
(Martin Pool)
255
256
* ``bzr export`` no longer exports ``.bzrrules``.
257
(Ian Clatworthy)
258
259
* ``bzr serve --directory=/`` now correctly allows the whole
260
filesystem to be accessed on Windows, not just the root of the drive
261
that Python is running from.
262
(Adrian Wilkins, #240910)
263
264
* Deleting directories by hand before running ``bzr rm`` will not
265
cause subsequent errors in ``bzr st`` and ``bzr commit``.
266
(Robert Collins, #150438)
267
268
* Fix a test case that was failing if encoding wasn't UTF-8.
269
(John Arbash Meinel, #247585)
270
271
* Fix "no buffer space available" error when branching with the new
272
smart server protocol to or from Windows.
273
(Andrew Bennetts, #246180)
274
275
* Fixed problem in branching from smart server.
276
(#249256, Michael Hudson, Martin Pool)
277
278
* Handle a file turning in to a directory in TreeTransform.

API Changes
282
***********
283
284
* ``MutableTree.commit`` has an extra optional keywork parameter
285
``exclude`` that will be unconditionally supplied by the command
286
line UI - plugins that add tree formats may need an update.
287
(Robert Collins)
288
289
* The API minimum version for plugin compatibility has been raised to
290
1.6 - there are significant changes throughout the code base.
291
(Robert Collins)
292
293
* The generic fetch code now uses three attributes on Repository objects
294
to control fetch. The streams requested are controlled via :
295
``_fetch_order`` and ``_fetch_uses_deltas``. Setting these
296
appropriately allows different repository implementations to recieve
297
data in their optimial form. If the ``_fetch_reconcile`` is set then
298
a reconcile operation is triggered at the end of the fetch.
299
(Robert Collins)
300
301
* The ``put_on_disk`` and ``get_tar_item`` methods in
302
``InventoryEntry`` were deprecated. (Ian Clatworthy)
303
304
* ``Repository.is_shared`` doesn't take a read lock. It didn't
305
need one in the first place (nobody cached the value, and
306
``RemoteRepository`` wasn't taking one either). This saves a round
307
trip when probing Pack repositories, as they read the ``pack-names``
308
file when locked. And during probe, locking the repo isn't very
309
useful. (John Arbash Meinel)
310
311
Internals
312
*********
313
314
* ``bzrlib.branchbuilder.BranchBuilder`` is now much more capable of
315
putting together a real history without having to create a full
316
WorkingTree. It is recommended that tests that are not directly
317
testing the WorkingTree use BranchBuilder instead. See
318
``BranchBuilder.build_snapshot`` or
319
``TestCaseWithMemoryTree.make_branch_builder``. (John Arbash Meinel)
320
321
* ``bzrlib.builtins.internal_tree_files`` broken into two giving a new
322
helper ``safe_relpath_files`` - used by the new ``exclude``
323
parameter to commit. (Robert Collins)
324
325
* Make it easier to introduce new WorkingTree formats.
326
(Ian Clatworthy)
327
328
* The code for exporting trees was refactored not to use the
329
deprecated ``InventoryEntry`` methods. (Ian Clatworthy)
330
331
* RuleSearchers return () instead of [] now when there are no matches.

338
:Released: 2008-07-17
339
340
This release adds a new 'stacked branches' feature allowing branches to
341
share storage without being in the same repository or on the same machine.
342
(See the user guide for more details.) It also adds a new hook, improved
343
weaves, aliases for related locations, faster bzr+ssh push, and several
344
bug fixes.
345
346
Features
347
********
348
349
* New ``pre_change_branch_tip`` hook that is called before the
350
branch tip is moved, while the branch is write-locked. See the User
351
Reference for signature details. (Andrew Bennetts)
352
353
* Rule-based preferences can now be defined for selected files in
354
selected branches, allowing commands and plugins to provide
355
custom behaviour for files matching defined patterns.
356
See ``Rule-based preferences`` (part of ``Configuring Bazaar``)
357
in the User Guide and ``bzr help rules`` for more information.
358
(Ian Clatworthy)
359
360
* Sites may suggest a branch to stack new branches on. (Aaron Bentley)
361
362
* Stacked branches are now supported. See ``bzr help branch`` and
363
``bzr help push``. Branches must be in the ``development1`` format
364
to stack, though the stacked-on branch can be of any format.
365
(Robert Collins)
366
367
Improvements
368
************
369
370
* ``bzr export --format=tgz --root=NAME -`` to export a gzipped tarball
371
to stdout; also ``tar`` and ``tbz2``.
372
(Martin Pool)
373
374
* ``bzr (re)merge --weave`` will now use a standard Weave algorithm,
375
rather than the annotation-based merge it was using. It does so by
376
building up a Weave of the important texts, without needing to build
377
the full ancestry. (John Arbash Meinel, #238895)
378
379
* ``bzr send`` documents and better supports ``emacsclient`` (proper
380
escaping of mail headers and handling of the MUA Mew).
381
(Christophe Troestler)
382
383
* Remembered locations can be specified by aliases, e.g. :parent, :public,
384
:submit. (Aaron Bentley)
385
386
* The smart protocol now has improved support for setting branches'
387
revision info directly. This makes operations like push
388
faster. The new request method name is
389
``Branch.set_last_revision_ex``. (Andrew Bennetts)
390
391
Bug Fixes
392
*********
393
394
* Bazaar is now able to be a client to the web server of IIS 6 and 7.
395
The broken implementations of RFC822 in Python and RFC2046 in IIS
396
combined with boundary-line checking in Bazaar previously made this
397
impossible. (NB, IIS 5 does not suffer from this problem).
398
(Adrian Wilkins, #247585)
399
400
* ``bzr log --long`` with a ghost in your mainline now handles that
401
ghost properly. (John Arbash Meinel, #243536)
402
403
* ``check`` handles the split-up .bzr layout correctly, so no longer
404
requires a branch to be present.
405
(Daniel Watkins, #64783)
406
407
* Clearer message about how to set the PYTHONPATH if bzrlib can't be
408
loaded.
409
(Martin Pool, #205230)
410
411
* Errors about missing libraries are now shown without a traceback,
412
and with a suggestion to install the library. The full traceback is
413
still in ``.bzr.log`` and can be shown with ``-Derror``.
414
(Martin Pool, #240161)
415
416
* Fetch from a stacked branch copies all required data.
417
(Aaron Bentley, #248506)
418
419
* Handle urls such as ftp://user@host.com@www.host.com where the user
420
name contains an @.
421
(Neil Martinsen-Burrell, #228058)
422
423
* ``needs_read_lock`` and ``needs_write_lock`` now suppress an error during
424
``unlock`` if there was an error in the original function. This helps
425
most when there is a failure with a smart server action, since often the
426
connection closes and we cannot unlock.
427
(Andrew Bennetts, John Arbash Meinel, #125784)
428
429
* Obsolete hidden command ``bzr fetch`` removed.
430
(Martin Pool, #172870)
431
432
* Raise the correct exception when doing ``-rbefore:0`` or ``-c0``.
433
(John Arbash Meinel, #239933)
434
435
* You can now compare file revisions in Windows diff programs from
436
Cygwin Bazaar.
437
(Matt McClure, #209281)
438
439
* revision_history now tolerates mainline ghosts for Branch format 6.
440
(Aaron Bentley, #235055)
441
442
* Set locale from environment for third party libs.
443

454
Testing
455
*******
456
457
* ``-Dmemory`` will cause /proc/PID/status to be catted before bzr
458
exits, allowing low-key analysis of peak memory use. (Robert Collins)
459
460
* ``TestCaseWithTransport.make_branch_and_tree`` tries harder to return
461
a tree with a ``branch`` attribute of the right format. This was
462
preventing some ``RemoteBranch`` tests from actually running with
463
``RemoteBranch`` instances. (Andrew Bennetts)
464
465
API Changes
466
***********
467
468
* Removed ``Repository.text_store``, ``control_store``, etc. Instead,
469
there are new attributes ``texts, inventories, revisions,
470
signatures``, each of which is a ``VersionedFiles``. See the
471
Repository docstring for more details.
472
(Robert Collins)
473
474
* ``Branch.pull`` now accepts an ``_override_hook_target`` optional
475
parameter. If you have a subclass of ``Branch`` that overrides
476
``pull`` then you should add this parameter. (Andrew Bennetts)
477
478
* ``bzrlib.check.check()`` has been deprecated in favour of the more
479
aptly-named ``bzrlib.check.check_branch()``.
480
(Daniel Watkins)
481
482
* ``Tree.print_file`` and ``Repository.print_file`` are deprecated.
483
These methods are bad APIs because they write directly to sys.stdout.
484
bzrlib does not use them internally, and there are no direct tests
485
for them. (Alexander Belchenko)
486
487
Internals
488
*********
489
490
* ``cat`` command no longer uses ``Tree.print_file()`` internally.
491
(Alexander Belchenko)
492
493
* New class method ``BzrDir.open_containing_tree_branch_or_repository``
494
which eases the discovery of the tree, the branch and the repository
495
containing a given location.
496
(Daniel Watkins)
497
498
* New ``versionedfile.KeyMapper`` interface to abstract out the access to
499
underlying .knit/.kndx etc files in repositories with partitioned
500
storage. (Robert Collins)
501
502
* Obsolete developer-use command ``weave-join`` has been removed.
503
(Robert Collins)
504
505
* ``RemoteToOtherFetcher`` and ``get_data_stream_for_search`` removed,
506
to support new ``VersionedFiles`` layering.

This release contains further progress towards our 1.6 goals of shallow
516
repositories, and contains a fix for some user-affecting bugs in the
517
repository layer. Building working trees during checkout and branch is
518
now faster.

520
Bug Fixes
521
*********
522
523
* Avoid KnitCorrupt error extracting inventories from some repositories.
524
(The data is not corrupt; an internal check is detecting a problem
525
reading from the repository.)
526
(Martin Pool, Andrew Bennetts, Robert Collins, #234748)
527
528
* ``bzr status`` was breaking if you merged the same revision twice.
529
(John Arbash Meinel, #235407)
530
531
* Fix infinite loop consuming 100% CPU when a connection is lost while
532
reading a response body via the smart protocol v1 or v2.
533
(Andrew Bennetts)
534
535
* Inserting a bundle which changes the contents of a file with no trailing
536
end of line, causing a knit snapshot in a 'knits' repository will no longer
537
cause KnitCorrupt. (Robert Collins)
538
539
* ``RemoteBranch.pull`` needs to return the ``self._real_branch``'s
540
pull result. It was instead just returning None, which breaks ``bzr
541
pull``. (John Arbash Meinel, #238149)
542
543
* Sanitize branch nick before using it as an attachment filename in
544
``bzr send``. (Lukáš Lalinský, #210218)
545
546
* Squash ``inv_entry.symlink_target`` to a plain string when
547
generating DirState details. This prevents from getting a
548
``UnicodeError`` when you have symlinks and non-ascii filenames.
549
(John Arbash Meinel, #135320)

551
Improvements
552
************
553
554
* Added the 'alias' command to set/unset and display aliases. (Tim Penhey)
555
556
* ``added``, ``modified``, and ``unknowns`` behaviour made consistent (all three
557
now quote paths where required). Added ``--null`` option to ``added`` and
558
``modified`` (for null-separated unknowns, use ``ls --unknown --null``)
559
(Adrian Wilkins)
560
561
* Faster branching (1.09x) and lightweight checkouts (1.06x) on large trees.
562
(Ian Clatworthy, Aaron Bentley)

*******
571
572
* Fix the test HTTPServer to be isolated from chdir calls made while it is
573
running, allowing it to be used in blackbox tests. (Robert Collins)

575
API Changes
576
***********
577
578
* ``WorkingTree.set_parent_(ids/trees)`` will now filter out revisions
579
which are in the ancestry of other revisions. So if you merge the same
580
tree twice, or merge an ancestor of an existing merge, it will only
581
record the newest. (If you merge a descendent, it will replace its
582
ancestor). (John Arbash Meinel, #235407)
583
584
* ``RepositoryPolicy.__init__`` now requires stack_on and stack_on_pwd,
585
through the derived classes do not. (Aaron Bentley)
586
587
Internals
588
*********
589
590
* ``bzrlib.bzrdir.BzrDir.sprout`` now accepts ``stacked`` to control
591
creating stacked branches. (Robert Collins)
592
593
* Knit record serialisation is now stricter on what it will accept, to
594
guard against potential internal bugs, or broken input. (Robert Collins)

:Released: 2008-06-02
600
601
Commands that work on the revision history such as push, pull, missing,
602
uncommit and log are now substantially faster. This release adds a
603
translation of some of the user documentation into Spanish. (Contributions of
604
other translations would be very welcome.) Bazaar 1.6beta1 adds a new network
605
protocol which is used by default and which allows for more efficient transfers
606
and future extensions.
607
608
609
Notes When Upgrading
610
********************
611
612
* There is a new version of the network protocol used for bzr://, bzr+ssh://
613
and bzr+http:// connections. This will allow more efficient requests and
614
responses, and more graceful fallback when a server is too old to
615
recognise a request from a more recent client. Bazaar 1.6 will
616
interoperate with 0.16 and later versions, but servers should be upgraded
617
when possible. Bazaar 1.6 no longer interoperates with 0.15 and earlier via
618
these protocols. Use alternatives like SFTP or upgrade those servers.
619
(Andrew Bennetts, #83935)
620
621
Changes
622
*******
623
624
* Deprecation warnings will not be suppressed when running ``bzr selftest``
625
so that developers can see if their code is using deprecated functions.
626
(John Arbash Meinel)
627
628
Features
629
********
630
631
* Adding ``-Derror`` will now display a traceback when a plugin fails to
632
load. (James Westby)
633
634
Improvements
635
************
636
637
* ``bzr branch/push/pull -r XXX`` now have a helper function for finding
638
the revno of the new revision (``Graph.find_distance_to_null``). This
639
should make something like ``bzr branch -r -100`` in a shared, no-trees
640
repository much snappier. (John Arbash Meinel)
641
642
* ``bzr log --short -r X..Y`` no longer needs to access the full revision
643
history. This makes it noticeably faster when logging the last few
644
revisions. (John Arbash Meinel)
645
646
* ``bzr ls`` now accepts ``-V`` as an alias for ``--versioned``.
647
(Jerad Cramp, #165086)
648
649
* ``bzr missing`` uses the new ``Graph.find_unique_ancestors`` and
650
``Graph.find_differences`` to determine missing revisions without having
651
to search the whole ancestry. (John Arbash Meinel, #174625)
652
653
* ``bzr uncommit`` now uses partial history access, rather than always
654
extracting the full revision history for a branch. This makes it
655
resolve the appropriate revisions much faster (in testing it drops
656
uncommit from 1.5s => 0.4s). It also means ``bzr log --short`` is one
657
step closer to not using full revision history.
658
(John Arbash Meinel, #172649)
659
660
Bugfixes
661
********
662
663
* ``bzr merge --lca`` should handle when two revisions have no common
664
ancestor other than NULL_REVISION. (John Arbash Meinel, #235715)
665
666
* ``bzr status`` was breaking if you merged the same revision twice.
667
(John Arbash Meinel, #235407)
668
669
* ``bzr push`` with both ``--overwrite`` and ``-r NNN`` options no longer
670
fails. (Andrew Bennetts, #234229)
671
672
* Correctly track the base URL of a smart medium when using bzr+http://
673
URLs, which was causing spurious "No repository present" errors with
674
branches in shared repositories accessed over bzr+http.
675
(Andrew Bennetts, #230550)
676
677
* Define ``_remote_is_at_least_1_2`` on ``SmartClientMedium`` so that all
678
implementations have the attribute. Fixes 'PyCurlTransport' object has no
679
attribute '_remote_is_at_least_1_2' attribute errors.
680
(Andrew Bennetts, #220806)
681
682
* Failure to delete an obsolete pack file should just give a warning
683
message, not a fatal error. It may for example fail if the file is still
684
in use by another process.
685
(Martin Pool)
686
687
* Fix MemoryError during large fetches over HTTP by limiting the amount of
688
data we try to read per ``recv`` call. The problem was observed with
689
Windows and a proxy, but might affect other environments as well.
690
(Eric Holmberg, #215426)
691
692
* Handle old merge directives correctly in Merger.from_mergeable. Stricter
693
get_parent_map requirements exposed a latent bug here. (Aaron Bentley)
694
695
* Issue a warning and ignore passwords declared in authentication.conf when
696
used for an ssh scheme (sftp or bzr+ssh).
697
(Vincent Ladeuil, #203186)
698
699
* Make both http implementations raise appropriate exceptions on 403
700
Forbidden when POSTing smart requests.
701
(Vincent Ladeuil, #230223)
702
703
* Properly *title* header names in http requests instead of capitalizing
704
them.
705
(Vincent Ladeuil, #229076)
706
707
* The "Unable to obtain lock" error message now also suggests using
708
``bzr break-lock`` to fix it. (Martin Albisetti, #139202)
709
710
* Treat an encoding of '' as ascii; this can happen when bzr is run
711
under vim on Mac OS X.
712
(Neil Martinsen-Burrell)
713
714
* ``VersionedFile.make_mpdiffs()`` was raising an exception that wasn't in
715
scope. (Daniel Fischer #235687)
716
717
Documentation
718
*************
719
720
* Added directory structure and started translation of docs in spanish.
721
(Martin Albisetti, Lucio Albenga)
722
723
* Incorporate feedback from Jelmer Vernooij and Neil Martinsen-Burrell
724
on the plugin and integration chapters of the User Guide.
725
(Ian Clatworthy)
726
727
* More Bazaar developer documentation about packaging and release process,
728
and about use of Python reprs.
729
(Martin Pool, Martin Albisetti)
730
731
* Updated Tortise strategy document. (Mark Hammond)
732
733
Testing
734
*******
735
736
* ``bzrlib.tests.adapt_tests`` was broken and unused - it has been fixed.
737
(Robert Collins)
738
739
* Fix the test HTTPServer to be isolated from chdir calls made while it is
740
running, allowing it to be used in blackbox tests. (Robert Collins)
741
742
* New helper function for splitting test suites
743
``split_suite_by_condition``. (Robert Collins)
744
745
Internals
746
*********
747
748
* ``Branch.missing_revisions`` has been deprecated. Similar functionality
749
can be obtained using ``bzrlib.missing.find_unmerged``. The api was
750
fairly broken, and the function was unused, so we are getting rid of it.
751
(John Arbash Meinel)
752
753
API Changes
754
***********
755
756
* ``Branch.abspath`` is deprecated; use the Tree or Transport
757
instead. (Martin Pool)
758
759
* ``Branch.update_revisions`` now takes an optional ``Graph``
760
object. This can be used by ``update_revisions`` when it is
761
checking ancestry, and allows callers to prefer request to go to a
762
local branch. (John Arbash Meinel)
763
764
* Branch, Repository, Tree and BzrDir should expose a Transport as an
765
attribute if they have one, rather than having it indirectly accessible
766
as ``.control_files._transport``. This doesn't add a requirement
767
to support a Transport in cases where it was not needed before;
768
it just simplifies the way it is reached. (Martin Pool)
769
770
* ``bzr missing --mine-only`` will return status code 0 if you have no
771
new revisions, but the remote does. Similarly for ``--theirs-only``.
772
The new code only checks one side, so it doesn't know if the other
773
side has changes. This seems more accurate with the request anyway.
774
It also changes the output to print '[This|Other] branch is up to
775
date.' rather than displaying nothing. (John Arbash Meinel)
776
777
* ``LockableFiles.put_utf8``, ``put_bytes`` and ``controlfilename``
778
are now deprecated in favor of using Transport operations.
779
(Martin Pool)
780
781
* Many methods on ``VersionedFile``, ``Repository`` and in
782
``bzrlib.revision`` deprecated before bzrlib 1.5 have been removed.
783
(Robert Collins)
784
785
* ``RevisionSpec.wants_revision_history`` can be set to False for a given
786
``RevisionSpec``. This will disable the existing behavior of passing in
787
the full revision history to ``self._match_on``. Useful for specs that
788
don't actually need access to the full history. (John Arbash Meinel)
789
790
* The constructors of ``SmartClientMedium`` and its subclasses now require a
791
``base`` parameter. ``SmartClientMedium`` implementations now also need
792
to provide a ``remote_path_from_transport`` method. (Andrew Bennetts)
793
794
* The default permissions for creating new files and directories
795
should now be obtained from ``BzrDir._get_file_mode()`` and
796
``_get_dir_mode()``, rather than from LockableFiles. The ``_set_file_mode``
797
and ``_set_dir_mode`` variables on LockableFiles which were advertised
798
as a way for plugins to control this are no longer consulted.
799
(Martin Pool)
800
801
* ``VersionedFile.join`` is deprecated. This method required local
802
instances of both versioned file objects and was thus hostile to being
803
used for streaming from a smart server. The new get_record_stream and
804
insert_record_stream are meant to efficiently replace this method.
805
(Robert Collins)
806
807
* ``WorkingTree.set_parent_(ids/trees)`` will now filter out revisions
808
which are in the ancestry of other revisions. So if you merge the same
809
tree twice, or merge an ancestor of an existing merge, it will only
810
record the newest. (If you merge a descendent, it will replace its
811
ancestor). (John Arbash Meinel, #235407)
812
813
* ``WorkingTreeFormat2.stub_initialize_remote`` is now private.
