:2.4b2: NOT RELEASED YET
13
External Compatibility Breaks
14
*****************************
16
.. These may require users to change the way they use Bazaar.
21
.. New commands, options, etc that users may wish to try out.
26
.. Improvements to existing commands, especially improved performance
27
or memory usage, or better results.
29
* When building a new WorkingTree (such as during ``bzr co`` or
30
``bzr branch``) we now properly store the stat and hash of files that
31
are old enough. This saves a fair amount of time on the first
32
``bzr status`` (on a 500MB tree, it saves about 30+s).
33
(John Arbash Meinel, #740932)
35
* Resolve ``lp:FOO`` urls locally rather than doing an XMLRPC request if
36
the user has done ``bzr launchpad-login``. The bzr+ssh URLs were already
37
being handed off to the remote server anyway (xmlrpc has been mapping
38
``lp:bzr`` to ``bzr+ssh://bazaar.launchpad.net/+branch/bzr``, rather
39
than ``bzr+ssh://bazaar.launchpad.net/~bzr-pqm/bzr/bzr.dev`` for a few
40
months now.) By doing it ourselves, we can cut out substantial startup
41
time. From Netherlands to London it was taking 368ms to do the XMLRPC
42
call as much as 2s from Sydney. You can test the local logic by using
43
``-Dlaunchpad``. (John Arbash Meinel, #397739)
48
.. Fixes for situations where bzr would previously crash or give incorrect
49
or undesirable results.
51
* Arguments that can't be decoded to unicode in the current posix locale give
52
a clearer error message without a traceback. (Martin [gz], #745712)
54
* ``bzrlib.log._DEFAULT_REQUEST_PARAMS`` is no longer accidentally
55
mutated by ``bzrlib.log._apply_log_request_defaults``. In practice
56
these default values aren't relied on very often so this probably
57
wasn't causing any trouble. (Andrew Bennetts)
59
* ``bzr log`` now works on revisions which are not in the current branch.
62
* Lazy hooks are now reset between test runs. (Jelmer Vernooij, #745566)
64
* Standalone bzr.exe installation on Windows: user can put additional python
65
libraries into ``site-packages`` subdirectory of the installation directory,
66
this might be required for "installing" extra dependencies for some plugins.
67
(Alexander Belchenko, #743256)
69
* ``TreeTransform.create_file/new_file`` can now take an optional ``sha1``
70
parameter. If supplied, when the transform is applied, it will then call
71
``self._tree._observed_sha1`` for those files. This lets us update the
72
hash-cache for content that we create, preventing us from re-reading the
73
content in the next ``bzr status``. (John Arbash Meinel, #740932)
78
* Added a section about using a shared SSH account on a server for bzr+ssh
79
access. (Russell Smith)
81
* The documentation now recommends using SSH rather than SFTP in the
82
tutorials and the examples, because that will generally be much faster
83
and better in cases where it can be used. SFTP is still available and
84
mentioned as an alternative. (Martin Pool, #636712)
89
.. Changes that may require updates in plugins or other code that uses
92
* ``Hooks.create_hook`` is now deprecated in favour of ``Hooks.add_hook``.
95
* If you call `bzrlib.initialize` but forget to enter the resulting object
96
as a context manager, bzrlib will now be initialized anyhow.
97
(Previously simple programs calling bzrlib might find the library was
101
* Inventory-specific functionality has been split out of ``Tree`` into
102
a new ``InventoryTree`` class. Tree instances no longer
103
necessarily provide an ``inventory`` attribute. (Jelmer Vernooij)
105
* New method ``Hooks.uninstall_named_hook``. (Jelmer Vernooij, #301472)
107
* ``revision_graph_can_have_wrong_parents`` is now an attribute
108
on ``RepositoryFormat`` rather than a method on ``Repository``.
111
* The ``revno`` parameter of ``log.LogRevision`` may now be None,
112
representing a revision which is not in the current branch.
113
(Matt Giuca, #241998)
115
* The various knit pack repository format classes have been moved
116
from ``bzrlib.repofmt.pack_repo`` to
117
``bzrlib.repofmt.knitpack_repo``. (Jelmer Vernooij)
122
.. Major internal changes, unlikely to be visible to users or plugin
123
developers, but interesting for bzr developers.
125
* Added ``osutils.lstat`` and ``osutils.fstat``. These are just the ``os``
126
functions on Linux, but they are wrapped on Windows so that fstat
127
matches lstat results across all python versions.
130
* ``WorkingTree._observed_sha1`` also updates the 'size' column. It
131
happened to be updated as a side-effect of commit, but if we start using
132
the function elsewhere we might as well do it directly.
138
.. Fixes and changes that are only relevant to bzr's test framework and
139
suite. This can include new facilities for writing tests, fixes to
140
spurious test failures and changes to the way things should be tested.
148
This is the first beta of the 2.4 series, leading up to a 2.4.0
149
release in August 2011. Beta releases are suitable for everyday use
150
but may cause some incompatibilities with plugins. Some plugins may need
151
small updates to work with 2.4b1.
153
External Compatibility Breaks
154
*****************************
161
* Added ``changelog_merge`` plugin for merging changes to ``Changelog`` files
162
in GNU format. See ``bzr help changelog_merge`` for details.
165
* Configuration options can now use references to other options in the same
166
file by enclosing them with curly brackets (``{other_opt}``). This makes it
167
possible to use, for example,
168
``push_location=lp:~vila/bzr/config-{nickname}`` in ``branch.conf`` when
169
using a loom. During the beta period, the default behaviour is to disable
170
this feature. It can be activated by declaring ``bzr.config.expand = True``
171
in ``bazaar.conf``. (Vincent Ladeuil)
173
* External merge tools can now be configured in bazaar.conf. See
174
``bzr help configuration`` for more information. (Gordon Tyler, #489915)
176
* The ``lp:`` directory service now supports Launchpad's QA staging.
177
(Jelmer Vernooij, #667483)
182
* A new hidden command ``bzr repair-workingtree``. This is a way to force
183
the dirstate file to be rebuilt, rather than using a ``bzr checkout``
184
workaround. (John Arbash Meinel)
186
* Added a ``Branch.heads_to_fetch`` RPC to the smart server protocol.
187
This allows formats from plugins (such as looms) to efficiently tell the
188
client which revisions need to be fetched. (Andrew Bennetts)
190
* Branching, merging and pulling a branch now copies revisions named in
191
tags, not just the tag metadata. (Andrew Bennetts, #309682)
193
* ``bzr cat-revision`` no longer requires a working tree.
194
(Jelmer Vernooij, #704405)
196
* ``bzr export --per-file-timestamps`` for .tar.gz files will now
197
override the mtime for trees exported on Python 2.7 and later, which
198
expose the 'mtime' field in gzip files. This makes the output of
199
``bzr export --per-file-timestamps`` for a particular tree
200
deterministic. (Jelmer Vernooij, #711226)
202
* ``bzr export --format=zip`` can now export to standard output,
203
like the other exporters can. (Jelmer Vernooij, #513752)
205
* ``bzr export`` can now create ``.tar.xz`` and ``.tar.lzma`` files.
206
(Jelmer Vernooij, #551714)
208
* Getting all entries from ``CHKInventory.iter_entries_by_dir()`` has been
209
sped up dramatically for large trees. Iterating by dir is not the best
210
way to load data from a CHK inventory, so it preloads all the items in
211
the correct order. (With the gcc-tree, this changes it (re)reading 8GB
212
of CHK data, down to just 150MB.) This has noticeable affects for things
213
like building checkouts, etc. (John Arbash Meinel, #737234)
219
* A MemoryError thrown on the server during a remote operation will now be
220
usefully reported, and other unexpected errors will include the class name.
221
(Martin [gz], #722416)
223
* ``bzr annotate -r-1 file`` will now properly annotate a deleted file.
224
(Andrew King, #537442)
226
* ``bzr export`` to zip files will now set a mode on directories.
227
(Jelmer Vernooij, #207253)
229
* ``bzr export`` to tgz files will only write out the basename of the
230
tarfile to the gzip file. (Jelmer Vernooij, #102234)
232
* ``bzr push --overwrite`` with an older revision specified will now correctly
233
roll back the target branch. (Jelmer Vernooij, #386576)
235
* ``bzr lp-propose`` can now propose merges against packaging branches on
236
Launchpad without requiring the target branch to be specified.
237
(Jelmer Vernooij, #704647)
239
* ``bzr lp-propose`` no longer requires a reviewer to be specified. It will
240
instead leave setting the reviewer up to Launchpad if it was not specified.
241
(Jelmer Vernooij, #583772)
243
* ``bzr pull`` will now exit with exit code 1 if there were tag conflicts.
244
(Jelmer Vernooij, #213185)
246
* ``bzr mv`` user errors no longer throw UnicodeEncodeError with non-ascii
247
paths, however they may still print junk if not on a UTF-8 terminal.
248
(Martin [gz], #707954)
250
* ``bzr reconfigure --unstacked`` now copies revisions (and their
251
ancestors) named in tags into the unstacked repository, not just the
252
ancestry of the branch's tip. (Andrew Bennetts, #401646)
254
* ``bzr serve`` no longer crashes when a server_started hook is installed and
255
IPv6 support is available on the system. (Jelmer Vernooij, #293697)
257
* ``bzr tags`` will no longer choke on branches with ghost revisions in
258
their mainline and tags on revisions not in the branch ancestry.
259
(Jelmer Vernooij, #397556)
261
* ``bzr whoami`` will now display an error if both a new identity and
262
``--email`` were specified. (Jelmer Vernooij, #680449)
264
* ``launchpadlib`` doesn't provide the ``uris`` module in some old versions.
265
(Vincent Ladeuil, #706835)
267
* Empty entries in the ``NO_PROXY`` variable are no longer treated as matching
269
(Martin Pool, #586341)
271
* Plugins incompatible with the current version of bzr no longer produce a
272
warning on every command invocation. Instead, a message is shown by
273
``bzr plugins`` and in crash reports.
274
(#704195, Martin Pool)
276
* The "pretty" version of ``needs_read_lock`` and ``needs_write_lock`` now
277
preserves the identity of default parameter values.
278
(Andrew Bennetts, #718569)
280
* ``bzr dump-btree --raw`` no longer tracebacks on a B-Tree file
281
containing no rows. (Eric Siegerman, #715508)
283
* Fix ``bzr lp-mirror`` to work on command line branch URLs and branches
284
without an explicit public location. (Max Bowsher)
286
* On Python 2.6 and higher, use multiprocessing.cpu_count() to retrieve the
287
number of available processors. (Jelmer Vernooij, #693140)
292
* Added ``Branch.heads_to_fetch`` method. Implementations of the Branch API
293
must now inherit or implement this method. (Andrew Bennetts, #721328)
295
* Added ``bzrlib.mergetools`` module with helper functions for working with
296
the list of external merge tools. (Gordon Tyler, #489915)
298
* All methods and arguments that were deprecated before 2.0
299
have been removed. (Jelmer Vernooij)
301
* Branch formats should now be registered on the format registry
302
(``bzrlib.branch.format_registry``) rather than using the class
303
methods on ``BranchFormat``. (Jelmer Vernooij, #714729)
305
* ``BranchFormat.supports_leaving_lock()`` and
306
``RepositoryFormat.supports_leaving_lock`` flags have been added.
309
* ``Branch.fetch`` implementations must now accept an optional
310
``fetch_spec`` keyword argument. (Andrew Bennetts)
312
* ``Branch.import_last_revision_info`` is deprecated. Use the
313
``import_last_revision_info_and_tags`` method instead.
316
* Because it was too specific to BzrDir implementations,
317
``ControlDir.sprout`` no longer has a default implementation; it now
318
raises ``NotImplementedError``. (Jelmer Vernooij, #717937)
320
* ``ControlDirFormat.register_format`` has been removed. Instead,
321
``Prober`` implementations should now implement a ``known_formats``
322
method. (Jelmer Vernooij)
324
* ControlDirFormats can now provide a ``check_status`` method and
325
raise a custom exception or warning when an unsupported or deprecated
326
format is being opened. (Jelmer Vernooij, #731311)
328
* ``bzrlib.revionspec.dwim_revspecs`` is deprecated.
329
Use ``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_revspec`` and
330
``bzrlib.revisionspec.RevisionSpec_dwim.append_possible_lazy_revspec``
331
instead. (Jelmer Vernooij, #721971)
333
* ``BzrDirFormat`` has a new attribute ``fixed_components`` that
334
indicates whether the components of the bzrdir can be upgraded
335
independent of the ``BzrDir``. (Jelmer Vernooij)
337
* ``BzrProber.register_format`` and ``BzrProber.unregister_format`` are
338
now deprecated in favour of the ``BzrProber.formats`` format registry.
341
* ``ControlDir`` implementations no longer have to provide the
342
``get_branch_transport``, ``get_workingtree_transport`` and
343
``get_repository_transport`` methods. (Jelmer Vernooij, #730325)
345
* ``Converter`` has been moved from ``bzrlib.bzrdir`` to
346
``bzrlib.controldir``. (Jelmer Vernooij)
348
* Repository formats can now provide
349
``_get_extra_interrepo_test_combinations`` in the same module
350
to provide extra test combinations for ``bzrlib.tests.per_repository``.
353
* Repository formats should now be registered on the format registry
354
(``bzrlib.repository.format_registry``) rather than using the class
355
methods on ``RepositoryFormat``. (Jelmer Vernooij)
357
* Repository formats can now indicate they do not support the full
358
VersionedFiles API by setting the ``supports_full_versioned_files``
359
attribute to False. A subset of the VersionedFiles API
360
(signatures and text graphs) still needs to be supported.
363
* Repository formats have a new method ``is_deprecated`` that
364
implementations can override to return True to trigger a deprecation
365
warning. (Jelmer Vernooij)
367
* The ``revision_id`` parameter of
368
``Repository.search_missing_revision_ids`` and
369
``InterRepository.search_missing_revision_ids`` is deprecated. It is
370
replaced by the ``revision_ids`` parameter. (Andrew Bennetts)
372
* Working tree formats should now be registered on the format registry
373
(``bzrlib.working_tree.format_registry``) rather than using the class
374
methods on ``WorkingTreeFormat``. (Jelmer Vernooij, #714730)
379
* ``CatchingExceptionThread`` (formerly ThreadWithException) has been moved
380
out of the ``bzrlib.tests`` hierarchy to make it clearer that it can be used
381
outside of tests. This class makes it easier to track exceptions in threads
382
by catching them so they can be re-raised in the controlling thread. It's
383
available in the ``bzrlib.cethread`` module. (Vincent Ladeuil)
385
* Correctly propogate malloc failures from diff-delta.c code as MemoryError
386
so OOM conditions during groupcompress are clearly reported. This entailed a
387
change to several function signatures. (Martin [gz], #633336)
389
* ``HookPoint.lazy_hook`` and ``Hooks.install_named_lazy_hook`` can install
390
hooks for which the callable is loaded lazily. (Jelmer Vernooij)
395
* The Range parsing for HTTP requests will correctly parse incomplete ranges.
