This release of Bazaar includes handy improvements to the speed of log and
14
status, new options for several commands, improved documentation, and better
15
hooks, including initial code for server-side hooks. A number of bugs have
16
been fixed, particularly in interoperability between different formats or
17
different releases of Bazaar over there network. There's been substantial
18
internal work in both the repository and network code to enable new features
19
and faster performance.

Bug Fixes
22
*********
23
24
* Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break
25
if the remote server was < version 1.2. This was due to a bug in the
26
RemoteRepository.get_parent_map() fallback code.

Bug Fixes
36
*********
37
38
* ``bzr log -r ..X bzr://`` was failing, because it was getting a request
39
for ``revision_id=None`` which was not a string.
40
(John Arbash Meinel, #211661)
41
42
* Fixed a bug in handling ghost revisions when logging changes in a
43
particular file. (John Arbash Meinel, #209948)
44
45
* Fix error about "attempt to add line-delta in non-delta knit".
46
(Andrew Bennetts, #205156)
47
48
* Fixed performance degradation in fetching from knit repositories to
49
knits and packs due to parsing the entire revisions.kndx on every graph
50
walk iteration fixed by using the Repository.get_graph API. There was
51
another regression in knit => knit fetching which re-read the index for
52
every revision each side had in common.

Changes
62
*******
63
64
* bzr main script cannot be imported (Benjamin Peterson)
65
66
* On GNU/Linux bzr additionally looks for plugins in arch-independent site
67
directory. (Toshio Kuratomi)
68
69
* The ``set_rh`` branch hook is now deprecated. Please migrate
70
any plugins using this hook to use an alternative, e.g.
71
``post_change_branch_tip``. (Ian Clatworthy)
72
73
* When a plugin cannot be loaded as the file path is not a valid
74
python module name bzr will now strip a ``bzr_`` prefix from the
75
front of the suggested name, as many plugins (e.g. bzr-svn)
76
want to be installed without this prefix. It is a common mistake
77
to have a folder named "bzr-svn" for that plugin, especially
78
as this is what bzr branch lp:bzr-svn will give you. (James Westby,
79
Andrew Cowie)
80
81
* UniqueIntegerBugTracker now appends bug-ids instead of joining
82
them to the base URL. Plugins that register bug trackers may
83
need a trailing / added to the base URL if one is not already there.
84
(James Wesby, Andrew Cowie)
85
86
Features
87
********
88
89
* Added start_commit hook for mutable trees. (Jelmer Vernooij, #186422)
90
91
* ``status`` now accepts ``--no-pending`` to show the status without
92
listing pending merges, which speeds up the command a lot on large
93
histories. (James Westby, #202830)
94
95
* New ``post_change_branch_tip`` hook that is called after the
96
branch tip is moved but while the branch is still write-locked.
97
See the User Reference for signature details.
98
(Ian Clatworthy, James Henstridge)
99
100
* Reconfigure can convert a branch to be standalone or to use a shared
101
repository. (Aaron Bentley)
102
103
Improvements
104
************
105
106
* The smart protocol now has support for setting branches' revision info
107
directly. This should make operations like push slightly faster, and is a
108
step towards server-side hooks. The new request method name is
109
``Branch.set_last_revision_info``. (Andrew Bennetts)
110
111
* ``bzr commit --fixes`` now recognises "gnome" as a tag by default.
112
(James Westby, Andrew Cowie)
113
114
* ``bzr switch`` will attempt to find branches to switch to relative to the
115
current branch. E.g. ``bzr switch branchname`` will look for
116
``current_branch/../branchname``. (Robert Collins, Jelmer Vernooij,
117
Wouter van Heyst)
118
119
* Diff is now more specific about execute-bit changes it describes
120
(Chad Miller)
121
122
* Fetching data over HTTP is a bit faster when urllib is used. This is done
123
by forcing it to recv 64k at a time when reading lines in HTTP headers,
124
rather than just 1 byte at a time. (Andrew Bennetts)
125
126
* Log --short and --line are much faster when -r is not specified.
127
(Aaron Bentley)
128
129
* Merge is faster. We no longer check a file's existence unnecessarily
130
when merging the execute bit. (Aaron Bentley)
131
132
* ``bzr status`` on an explicit list of files no longer shows pending
133
merges, making it much faster on large trees. (John Arbash Meinel)
134
135
* The launchpad directory service now warns the user if they have not set
136
their launchpad login and are trying to resolve a URL using it, just
137
in case they want to do a write operation with it. (James Westby)
138
139
* The smart protocol client is slightly faster, because it now only queries
140
the server for the protocol version once per connection. Also, the HTTP
141
transport will now automatically probe for and use a smart server if
142
one is present. You can use the new ``nosmart+`` transport decorator
143
to get the old behaviour. (Andrew Bennetts)
144
145
* The ``version`` command takes a ``--short`` option to print just the
146
version number, for easier use in scripts. (Martin Pool)
147
148
* Various operations with revision specs and commands that calculate
149
revnos and revision ids are faster. (John A. Meinel, Aaron Bentley)
150
151
Bugfixes
152
********
153
154
* Add ``root_client_path`` parameter to SmartWSGIApp and
155
SmartServerRequest. This makes it possible to publish filesystem
156
locations that don't exactly match URL paths. SmartServerRequest
157
subclasses should use the new ``translate_client_path`` and
158
``transport_from_client_path`` methods when dealing with paths received
159
from a client to take this into account. (Andrew Bennetts, #124089)
160
161
* ``bzr mv a b`` can be now used also to rename previously renamed
162
directories, not only files. (Lukáš Lalinský, #107967)
163
164
* ``bzr uncommit --local`` can now remove revisions from the local
165
branch to be symmetric with ``bzr commit --local``.
166
(John Arbash Meinel, #93412)
167
168
* Don't ask for a password if there is no real terminal.
169
(Alexander Belchenko, #69851)
170
171
* Fix a bug causing a ValueError crash in ``parse_line_delta_iter`` when
172
fetching revisions from a knit to pack repository or vice versa using
173
bzr:// (including over http or ssh).
174
(#208418, Andrew Bennetts, Martin Pool, Robert Collins)
175
176
* Fixed ``_get_line`` in ``bzrlib.smart.medium``, which was buggy. Also
177
fixed ``_get_bytes`` in the same module to use the push back buffer.
178
These bugs had no known impact in normal use, but were problematic for
179
developers working on the code, and were likely to cause real bugs sooner
180
or later. (Andrew Bennetts)
181
182
* Implement handling of basename parameter for DefaultMail. (James Westby)
183
184
* Incompatibility with Paramiko versions newer than 1.7.2 was fixed.
185
(Andrew Bennetts, #213425)
186
187
* Launchpad locations (lp: URLs) can be pulled. (Aaron Bentley, #181945)
188
189
* Merges that add files to deleted root directories complete. They
190
do create conflicts. (Aaron Bentley, #210092)
191
192
* vsftp's return ``550 RNFR command failed.`` supported.
193
(Marcus Trautwig, #129786)
194
195
Documentation
196
*************
197
198
* Improved documentation on send/merge relationship. (Peter Schuller)
199
200
* Minor fixes to the User Guide. (Matthew Fuller)
201
202
* Reduced the evangelism in the User Guide. (Ian Clatworthy)
203
204
* Added Integrating with Bazaar document for developers (Martin Albisetti)
205
206
API Breaks
207
**********
208
209
* Attempting to pull data from a ghost aware repository (e.g. knits) into a
210
non-ghost aware repository such as weaves will now fail if there are
211
ghosts. (Robert Collins)
212
213
* ``KnitVersionedFile`` no longer accepts an ``access_mode`` parameter, and
214
now requires the ``index`` and ``access_method`` parameters to be
215
supplied. A compatible shim has been kept in the new function
216
``knit.make_file_knit``. (Robert Collins)
217
218
* Log formatters must now provide log_revision instead of show and
219
show_merge_revno methods. The latter had been deprecated since the 0.17
220
release. (James Westby)
221
222
* ``LoopbackSFTP`` is now called ``SocketAsChannelAdapter``.
223
(Andrew Bennetts)
224
225
* ``osutils.backup_file`` is removed. (Alexander Belchenko)
226
227
* ``Repository.get_revision_graph`` is deprecated, with no replacement
228
method. The method was size(history) and not desirable. (Robert Collins)
229
230
* ``revision.revision_graph`` is deprecated, with no replacement function.
231
The function was size(history) and not desirable. (Robert Collins)
232
233
* ``Transport.get_shared_medium`` is deprecated. Use
234
``Transport.get_smart_medium`` instead. (Andrew Bennetts)
235
236
* ``VersionedFile`` factories now accept a get_scope parameter rather
237
than using a call to ``transaction_finished``, allowing the removal of
238
the fixed list of versioned files per repository. (Robert Collins)
239
240
* ``VersionedFile.annotate_iter`` is deprecated. While in principle this
241
allowed lower memory use, all users of annotations wanted full file
242
annotations, and there is no storage format suitable for incremental
243
line-by-line annotation. (Robert Collins)
244
245
* ``VersionedFile.clone_text`` is deprecated. This performance optimisation
246
is no longer used - reading the content of a file that is undergoing a
247
file level merge to identical state on two branches is rare enough, and
248
not expensive enough to special case. (Robert Collins)
249
250
* ``VersionedFile.clear_cache`` and ``enable_cache`` are deprecated.
251
These methods added significant complexity to the ``VersionedFile``
252
implementation, but were only used for optimising fetches from knits -
253
which can be done from outside the knit layer, or via a caching
254
decorator. As knits are not the default format, the complexity is no
255
longer worth paying. (Robert Collins)
256
257
* ``VersionedFile.create_empty`` is removed. This method presupposed a
258
sensible mapping to a transport for individual files, but pack backed
259
versioned files have no such mapping. (Robert Collins)
260
261
* ``VersionedFile.get_graph`` is deprecated, with no replacement method.
262
The method was size(history) and not desirable. (Robert Collins)
263
264
* ``VersionedFile.get_graph_with_ghosts`` is deprecated, with no
265
replacement method. The method was size(history) and not desirable.
266
(Robert Collins)
267
268
* ``VersionedFile.get_parents`` is deprecated, please use
269
``VersionedFile.get_parent_map``. (Robert Collins)
270
271
* ``VersionedFile.get_sha1`` is deprecated, please use
272
``VersionedFile.get_sha1s``. (Robert Collins)
273
274
* ``VersionedFile.has_ghost`` is now deprecated, as it is both expensive
275
and unused outside of a single test. (Robert Collins)
276
277
* ``VersionedFile.iter_parents`` is now deprecated in favour of
278
``get_parent_map`` which can be used to instantiate a Graph on a
279
VersionedFile. (Robert Collins)
280
281
* ``VersionedFileStore`` no longer uses the transaction parameter given
282
to most methods; amongst other things this means that the
283
get_weave_or_empty method no longer guarantees errors on a missing weave
284
in a readonly transaction, and no longer caches versioned file instances
285
which reduces memory pressure (but requires more careful management by
286
callers to preserve performance). (Robert Collins)
287
288
Testing
289
*******
290
291
* New -Dselftest_debug flag disables clearing of the debug flags during
292
tests. This is useful if you want to use e.g. -Dhpss to help debug a
293
failing test. Be aware that using this feature is likely to cause
294
spurious test failures if used with the full suite. (Andrew Bennetts)
295
296
* selftest --load-list now uses a new more agressive test loader that will
297
avoid loading unneeded modules and building their tests. Plugins can use
298
this new loader by defining a load_tests function instead of a test_suite
299
function. (a forthcoming patch will provide many examples on how to
300
implement this).
301
(Vincent Ladeuil)
302
303
* selftest --load-list now does some sanity checks regarding duplicate test
304
IDs and tests present in the list but not found in the actual test suite.
305
(Vincent Ladeuil)
306
307
* Slightly more concise format for the selftest progress bar, so there's
308
more space to show the test name. (Martin Pool) ::
309
310
[2500/10884, 1fail, 3miss in 1m29s] test_revisionnamespaces.TestRev
311
312
* The test suite takes much less memory to run, and is a bit faster. This
313
is done by clearing most attributes of TestCases after running them, if
314
they succeeded. (Andrew Bennetts)
315
316
Internals
317
*********
318
319
* Added ``_build_client_protocol`` to ``_SmartClient``. (Andrew Bennetts)
320
321
* Added basic infrastructure for automatic plugin suggestion.
322
(Martin Albisetti)
323
324
* If a ``LockableFiles`` object is not explicitly unlocked (for example
325
because of a missing ``try/finally`` block, it will give a warning but
326
not automatically unlock itself. (Previously they did.) This
327
sometimes caused knock-on errors if for example the network connection
328
had already failed, and should not be relied upon by code.
329
(Martin Pool, #109520)
330
331
* ``make dist`` target to build a release tarball, and also
332
``check-dist-tarball`` and ``dist-upload-escudero``. (Martin Pool)
333
334
* The ``read_response_tuple`` method of ``SmartClientRequestProtocol*``
335
classes will now raise ``UnknownSmartMethod`` when appropriate, so that
336
callers don't need to try distinguish unknown request errors from other
337
errors. (Andrew Bennetts)
338
339
* ``set_make_working_trees`` is now implemented provided on all repository
340
implementations (Aaron Bentley)
341
342
* ``VersionedFile`` now has a new method ``get_parent_map`` which, like
343
``Graph.get_parent_map`` returns a dict of key:parents. (Robert Collins)
