This release fixes two small but worthwhile bugs relevant to users on
15
Microsoft Windows: some commands that failed on with locking errors will
16
now work, and a bug that caused poor performance after committing a file
17
with line-ending conversion has now been fixed. It also fixes a bug in
18
pushing to older servers.
23
* Fixed a problem where using content filtering and especially end-of-line
24
conversion will commit too many copies a file.
25
(Martin Pool, #415508)
27
* Fix assertion error about ``_remember_remote_is_before`` in
28
``set_tags_bytes`` when pushing to older smart servers.
29
(Andrew Bennetts, Alexander Belchenko, #418931)
34
* ``bzr push`` locally on Windows will no longer give a locking error with
35
dirstate based formats. (Robert Collins)
37
* ``bzr shelve`` and ``bzr unshelve`` now work on Windows.
38
(Robert Collins, #305006)
43
* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its
44
classes changed to manage lock lifetime of the trees they open in a way
45
consistent with reader-exclusive locks. (Robert Collins, #305006)
47
* ``Tree.path_content_summary`` may return a size of None, when called on
48
a tree with content filtering where the size of the canonical form
49
cannot be cheaply determined. (Martin Pool)
51
* When manually creating transport servers in test cases, a new helper
52
``TestCase.start_server`` that registers a cleanup and starts the server
53
should be used. (Robert Collins)
61
* Committing directly to a stacked branch from a lightweight checkout will
62
no longer work. In previous versions this would appear to work but would
63
generate repositories with insufficient data to create deltas, leading
64
to later errors when branching or reading from the repository.
65
(Robert Collins, bug #375013)
73
* Fetching from 2a branches from a version-2 bzr protocol would fail to
74
copy the internal inventory pages from the CHK store. This cannot happen
75
in normal use as all 2a compatible clients and servers support the
76
version-3 protocol, but it does cause test suite failures when testing
77
downlevel protocol behaviour. (Robert Collins)
79
* Fix a test failure on karmic by making a locale test more robust.
80
(Vincent Ladeuil, #413514)
82
* Fixed "Pack ... already exists" error when running ``bzr pack`` on a
83
fully packed 2a repository. (Andrew Bennetts, #382463)
85
* Further tweaks to handling of ``bzr add`` messages about ignored files.
86
(Jason Spashett, #76616)
88
* Properly handle fetching into a stacked branch while converting the
89
data, especially when there are also ghosts. The code was filling in
90
parent inventories incorrectly, and also not handling when one of the
91
parents was a ghost. (John Arbash Meinel, #402778, #412198)
93
* ``RemoteStreamSource.get_stream_for_missing_keys`` will fetch CHK
94
inventory pages when appropriate (by falling back to the vfs stream
95
source). (Andrew Bennetts, #406686)
97
* StreamSource generates rich roots from non-rich root sources correctly
98
now. (Andrew Bennetts, #368921)
100
* When deciding whether a repository was compatible for upgrading or
101
fetching, we previously incorrectly checked the default repository
102
format for the bzrdir format, rather than the format that was actually
103
present on disk. (Martin Pool, #408824)
108
* A better description of the platform is shown in crash tracebacks, ``bzr
109
--version`` and ``bzr selftest``.
110
(Martin Pool, #409137)
112
* Cross-format fetches (such as between 1.9-rich-root and 2a) via the
113
smart server are more efficient now. They send inventory deltas rather
114
than full inventories. The smart server has two new requests,
115
``Repository.get_stream_1.19`` and ``Repository.insert_stream_1.19`` to
116
support this. (Andrew Bennetts, #374738, #385826)
118
* Extracting the full ancestry and computing the ``merge_sort`` is now
119
significantly faster. This effects things like ``bzr log -n0``. (For
120
example, ``bzr log -r -10..-1 -n0 bzr.dev`` is 2.5s down to 1.0s.
132
* ``-Dstrict_locks`` can now be used to check that read and write locks
133
are treated properly w.r.t. exclusivity. (We don't try to take an OS
134
read lock on a file that we already have an OS write lock on.) This is
135
now set by default for all tests, if you have a test which cannot be
136
fixed, you can use ``self.thisFailsStrictLockCheck()`` as a
137
compatibility knob. (John Arbash Meinel)
139
* InterDifferingSerializer is now only used locally. Other fetches that
140
would have used InterDifferingSerializer now use the more network
141
friendly StreamSource, which now automatically does the same
142
transformations as InterDifferingSerializer. (Andrew Bennetts)
144
* ``KnownGraph`` now has a ``.topo_sort`` and ``.merge_sort`` member which
145
are implemented in pyrex and significantly faster. This is exposed along
146
with ``CombinedGraphIndex.find_ancestry()`` as
147
``VersionedFiles.get_known_graph_ancestry(keys)``.
150
* RemoteBranch.open now honours ignore_fallbacks correctly on bzr-v2
151
protocols. (Robert Collins)
153
* The index code now has some specialized routines to extract the full
154
ancestry of a key in a more efficient manner.
155
``CombinedGraphIndex.find_ancestry()``. (Time to get ancestry for
156
bzr.dev drops from 1.5s down to 300ms. For OOo from 33s => 10.5s) (John
162
* Install the test ssl certificate and key so that installed bzr
163
can run the https tests. (Denys Duchier, #392401)

:Codename: little traveller
173
This release of Bazaar marches on towards the 2.0 release in which the 2a
174
'brisbane-core' format becomes generally recommended. Most of the work in
175
this release now focusses on bug fixes and stabilization, covering both 2a
176
and previous formats. There is a new text-mode interactive merge feature,
177
a new guide to migration to 2a format in the user documentation, and
178
pushing branches to a smart server is now much faster.
180
The Bazaar team decided that 2.0 will be a long-term supported release,
181
with bugfix-only releases based on it continuing for at least six months
182
or until the following stable release.
184
There are no changes from 1.18rc1 to 1.18.
189
* ``bzr merge --interactive`` applies a user-selected portion of the
190
merge. The UI is similar to ``shelve``. (Aaron Bentley)
192
* ``bzr reconfigure`` now takes options ``--stacked-on URL`` and
193
``--unstacked`` to change stacking of a branch.
194
(Martin Pool, #391411)
199
* Annotating on a stacked branch will now succeed in simple scenarios.
200
There are still some complex scenarios where it will fail (bug #399884)
201
(John Arbash Meinel, #393366)
203
* A progress bar is no longer left dangling when ``bzr selftest``
204
completes, and the progress bar updates with zero latency so the
205
displayed test name is always the one that's actually running.
206
(Martin Pool, #123688)
208
* Authenticating against an SSH server now uses ``auth_none`` to determine
209
if password authentication is even supported. This fixes a bug where
210
users would be prompted for a launchpad password, even though launchpad
211
only supports publickey authentication. (John Arbash Meinel, #375867)
213
* BranchBuilder now accepts timezone to avoid test failures in countries far
214
from GMT. (Vincent Ladeuil, #397716)
216
* ``bzr commit`` no longer saves the unversioning of missing files until
217
the commit has completed on the branch. This means that aborting a
218
commit that found a missing file will leave the tree unedited.
219
(Robert Collins, #282402)
221
* ``bzr mv`` no longer takes out branch locks, which allows it to work
222
when the branch is readonly. (Robert Collins, #216541)
224
* ``bzr revert .`` no longer generates an InconsistentDelta error when
225
there are missing subtrees. (Robert Collins, #367632)
227
* ``bzr send`` now generates valid bundles with ``--2a`` formats. However,
228
do to internal changes necessary to support this, older clients will
229
fail when trying to insert them. For newer clients, the bundle can be
230
used to apply the changes to any rich-root compatible format.
231
(John Arbash Meinel, #393349)
233
* Cope with FTP servers that don't support restart/append by falling back
234
to reading and then rewriting the whole file, such as TahoeLAFS. (This
235
fallback may be slow for some access patterns.) (Nils Durner, #294709)
237
* Encode the paths in ``mbcs`` encoding on Windows when spawning an
238
external diff client. This at least allows supporting filenames that are
239
not ascii, but are present in the current locale. Ideally we would be
240
able to pass the Unicode path, but that would be client dependent.
241
(John Arbash Meinel, #382709)
243
* Fix a compile bug on Solaris having to do with const and
244
pointer-to-pointers. (John Arbash Meinel, #408441)
246
* Fixed a NameError that occurs when merging or pulling from a URL that
247
causes a redirection loop when bzr tries to read a URL as a bundle.
248
(Andrew Bennetts, #400847)
250
* Fix ``AttributeError: 'TestUIFactory' object has no attribute 'tick'``
251
running send and similar commands on 2a formats.
252
(Martin Pool, #408201)
254
* Fix crash in some invocations of ``bzr status`` in format 2a.
255
(Martin Pool, #403523)
257
* Fixed export to existing directory: if directory is empty then export
258
will succeed, otherwise it fails with error.
259
(Alexander Belchenko, #406174)
261
* Fixed spurious "Source branch does not support stacking" warning when
262
pushing. (Andrew Bennetts, #388908)
264
* Fixed spurious transport activity indicator appearing while tests are
265
running. (Martin Pool, #343532)
267
* Merge now correctly handles empty right-hand revision specs.
268
(Aaron Bentley, #333961)
270
* Renames to lexographically lower basenames in trees that have never been
271
committed to will no longer corrupt the dirstate. This was caused by an
272
bug in the dirstate update_minimal method. (Robert Collins, #395556)
274
* Requests for unknown methods no longer cause the smart server to log
275
lots of backtraces about ``UnknownSmartMethod``, ``do_chunk`` or
276
``do_end``. (Andrew Bennetts, #338561)
278
* Shelve will not shelve the initial add of the tree root. (Aaron Bentley)
280
* Streaming from bzr servers where there is a chain of stacked branches
281
(A stacked on B stacked on C) will now work. (Robert Collins, #406597)
283
* The environment variable ``BZR_PROGRESS_BAR`` set to either ``text`` or ``none``
284
always forces progress bars either on or off respectively. Otherwise,
285
they're turned on if ``TERM`` is not ``dumb`` and stderr is a terminal.
286
bzr always uses the 'text' user interface when run as a command, so
287
``BZR_USE_TEXT_UI`` is no longer needed.
288
(Martin Pool, #339385, #387717)
290
* The optional ``_knit_load_data_pyx`` C extension was never being
291
imported. This caused significant slowdowns when reading data from
292
repositories. (Andrew Bennetts, #405653)
294
* The ``--hardlink`` option to ``branch`` and ``checkout`` is not
295
supported at the moment on workingtree formats that can do content
296
filtering. (See <https://bugs.launchpad.net/bzr/+bug/408193>.)
297
bzr now says so, rather than just ignoring the option. (Martin Pool)
299
* There was a bug in ``osutils.relpath`` that was only triggered on
300
Windows. Essentially if you were at the root of a drive, and did
301
something to a branch/repo on another drive, we would go into an
302
infinite loop while trying to find a 'relative path'.
303
(John Arbash Meinel, #394227)
305
* ``WorkingTree4.unversion`` will no longer fail to unversion ids which
306
were present in a parent tree but renamed in the working tree.
307
(Robert Collins, #187207)
312
* Can now rename/move files even if they have been removed from the inventory.
315
* Pushing branches with tags via ``bzr://`` and ``bzr+ssh://`` is much
316
faster, using a new ``Branch.set_tags_bytes`` smart server verb rather
317
than VFS methods. For example, pushes of small branches with tags take
318
11 rather than 18 smart server requests. (Andrew Bennetts, #398608)
320
* Sending Ctrl-Break on Windows will now drop you into the debugger, in
321
the same way that sending Ctrl-\\ does on other platforms.
327
* Added Bazaar 2.0 Upgrade Guide. (Ian Clatworthy)
332
* ``CLIUIFactory`` is deprecated; use ``TextUIFactory`` instead if you
333
need to subclass or create a specific class, or better yet the existing
334
``make_ui_for_terminal``. ``SilentUIFactory`` is clarified to do no
335
user interaction at all, rather than trying to read from stdin but not
336
writing any output, which would be strange if reading prompts or
337
passwords. (Martin Pool)
339
* New TransformPreview.commit() allows committing without a working tree.
342
* ``pb`` parameter to ``TextTestResult`` is deprecated and ignored.
345
* ProgressTasks now prefer to talk direct to their ProgressView not to the
349
* ``WorkingTree._check`` now requires a references dict with keys matching
350
those returned by ``WorkingTree._get_check_refs``. (Robert Collins)
355
* ``CHKInventory.path2id`` uses the parent_id to basename hash to avoid
356
reading the entries along the path, reducing work to lookup ids from
357
paths. (Robert Collins)
359
* ``CHKMap.apply_delta`` now raises ``InconsistentDelta`` if a delta adds
360
as new a key which was already mapped. (Robert Collins)
362
* Inventory delta application catches more cases of corruption and can
363
prevent corrupt deltas from affecting consistency of data structures on
364
disk. (Robert Collins)
366
* --subunit support now adds timestamps if the subunit version supports
369
* The Windows all-in-one installer now bundles the PyQt image format
370
plugins, which allows previewing more images as part of 'qdiff'.
371
(Alexander Belchenko)
377
* Merge directive cherrypick tests must use the same root id.
378
(Martin Pool, #409684)
380
* Spurious failure in ``check`` tests on rich-root formats fixed.
381
(Martin Pool, #408199)
383
* The ``bzrlib.tests.TextTestRunner`` will no longer call
384
``countTestsCases`` on the test being run. Progress information is
385
instead handled by having the test passed in call ``result.progress``
386
before running its contents. This improves the behaviour when using
387
``TextTestRunner`` with test suites that don't support
388
``countTestsCases``. (Robert Collins)
