Bazaar 1.4rc1
Bazaar is now faster at status, merge and log, and has improved usability for those commands and also switch and diff. Both user and developer documentation is improved, as is integration with emacs, the GNOME bug tracker, and other bug trackers.

Release notes
bzr 1.4rc1 2008-04-11
-------
NOTES WHEN UPGRADING:
CHANGES:
* bzr main script cannot be imported (Benjamin Peterson)
* On Linux bzr additionally looks for plugins in arch-independent site
directory. (Toshio Kuratomi)
* The ``set_rh`` branch hook is now deprecated. Please migrate
any plugins using this hook to use an alternative, e.g.
``
* When a plugin cannot be loaded as the file path is not a valid
python module name bzr will now strip a ``bzr_`` prefix from the
front of the suggested name, as many plugins (e.g. bzr-svn)
want to be installed without this prefix. It is a common mistake
to have a folder named "bzr-svn" for that plugin, especially
as this is what bzr branch lp:bzr-svn will give you. (James Westby,
Andrew Cowie)
* UniqueIntegerBu
them to the base URL. Plugins that register bug trackers may
need a trailing / added to the base URL if one is not already there.
(James Wesby, Andrew Cowie)
FEATURES:
* Added mail-mode GNU Emacs mail package as a mail_client.
(Xavier Maillard, Bojan Nikolic)
* Added start_commit hook for mutable trees. (Jelmer Vernooij, #186422)
* ``status`` now accepts ``--no-pending`` to show the status without
listing pending merges, which speeds up the command a lot on large
histories. (James Westby, #202830)
* New ``post_
branch tip is moved but while the branch is still write-locked.
See the User Reference for signature details.
(Ian Clatworthy, James Henstridge)
IMPROVEMENTS:
* The smart protocol now has support for setting branches' revision info
directly. This should make operations like push slightly faster, and is a
step towards server-side hooks. The new request method name is
`
* ``bzr commit --fixes`` now recognises "gnome" as a tag by default.
(James Westby, Andrew Cowie)
* ``bzr switch`` will attempt to find branches to switch to relative to the
current branch. E.g. ``bzr switch branchname`` will look for
`
Wouter van Heyst)
* Diff is now more specific about execute-bit changes it describes
(Chad Miller)
* Fetching data over HTTP is a bit faster when urllib is used. This is done
by forcing it to recv 64k at a time when reading lines in HTTP headers,
rather than just 1 byte at a time. (Andrew Bennetts)
* Log --short and --line are much faster when -r is not specified.
(Aaron Bentley)
* Merge is faster. We no longer check a file's existence unnecessarily
when merging the execute bit. (Aaron Bentley)
* ``bzr status`` on an explicit list of files no longer shows pending
merges, making it much faster on large trees. (John Arbash Meinel)
* The launchpad directory service now warns the user if they have not set
their launchpad login and are trying to resolve a URL using it, just
in case they want to do a write operation with it. (James Westby)
* The smart protocol client is slightly faster, because it now only queries
the server for the protocol version once per connection. Also, the HTTP
transport will now automatically probe for and use a smart server if
one is present. You can use the new ``nosmart+`` transport decorator
to get the old behaviour. (Andrew Bennetts)
* The ``version`` command takes a ``--short`` option to print just the
version number, for easier use in scripts. (Martin Pool)
* Various operations with revision specs and commands that calculate
revnos and revision ids are faster. (John A. Meinel, Aaron Bentley)
BUGFIXES:
* Add ``root_
SmartServ
locations that don't exactly match URL paths. SmartServerRequest
subclasses should use the new ``translate_
`
from a client to take this into account. (Andrew Bennetts, #124089)
* ``bzr mv a b`` can be now used also to rename previously renamed
directories, not only files. (Lukáš Lalinský, #107967)
* ``bzr uncommit --local`` can now remove revisions from the local
branch to be symmetric with ``bzr commit --local``.
(John Arbash Meinel, #93412)
* Don't ask for a password if there is no real terminal.
(Alexander Belchenko, #69851)
* Fix a bug causing a ValueError crash in ``parse_
fetching revisions from a knit to pack repository or vice versa using
bzr:// (including over http or ssh).
(#208418, Andrew Bennetts, Martin Pool, Robert Collins)
* Fixed ``_get_line`` in ``bzrlib.
fixed ``_get_bytes`` in the same module to use the push back buffer.
These bugs had no known impact in normal use, but were problematic for
developers working on the code, and were likely to cause real bugs sooner
or later. (Andrew Bennetts)
* Implement handling of basename parameter for DefaultMail. (James Westby)
* Incompatibility with Paramiko versions newer than 1.7.2 was fixed.
(Andrew Bennetts, #213425)
* Launchpad locations (lp: URLs) can be pulled. (Aaron Bentley, #181945)
* Merges that add files to deleted root directories complete. They
do create conflicts. (Aaron Bentley, #210092)
* vsftp's return ``550 RNFR command failed.`` supported.
(Marcus Trautwig, #129786)
DOCUMENTATION:
* Improved documentation on send/merge relationship. (Peter Schuller)
* Minor fixes to the User Guide. (Matthew Fuller)
* Reduced the evangelism in the User Guide. (Ian Clatworthy)
* Added Integrating with Bazaar document for developers (Martin Albisetti)
API BREAKS:
* Attempting to pull data from a ghost aware repository (e.g. knits) into a
non-ghost aware repository such as weaves will now fail if there are
ghosts. (Robert Collins)
* ``KnitVersioned
now requires the ``index`` and ``access_method`` parameters to be
supplied. A compatible shim has been kept in the new function
`
* Log formatters must now provide log_revision instead of show and
show_
release. (James Westby)

method. The method was size(history) and not desirable. (Robert Collins)
* ``revision.
The function was size(history) and not desirable. (Robert Collins)
* ``Transport.
`
* ``VersionedFile`` factories now accept a get_scope parameter rather
than using a call to ``transaction_
the fixed list of versioned files per repository. (Robert Collins)
* ``VersionedFile
allowed lower memory use, all users of annotations wanted full file
annotations, and there is no storage format suitable for incremental
line-by-line annotation. (Robert Collins)
* ``VersionedFile
is no longer used - reading the content of a file that is undergoing a
file level merge to identical state on two branches is rare enough, and
not expensive enough to special case. (Robert Collins)
* ``VersionedFile
These methods added significant complexity to the ``VersionedFile``
implement
which can be done from outside the knit layer, or via a caching
decorator. As knits are not the default format, the complexity is no
longer worth paying. (Robert Collins)
* ``VersionedFile

versioned files have no such mapping. (Robert Collins)
* ``VersionedFile

* ``VersionedFile

in a readonly transaction, and no longer caches versioned file instances
which reduces memory pressure (but requires more careful management by
callers to preserve performance). (Robert Collins)
TESTING:
* New -Dselftest_debug flag disables clearing of the debug flags during
tests. This is useful if you want to use e.g. -Dhpss to help debug a
failing test. Be aware that using this feature is likely to cause
spurious test failures if used with the full suite. (Andrew Bennetts)
* selftest --load-list now uses a new more agressive test loader that will
avoid loading unneeded modules and building their tests. Plugins can use
this new loader by defining a load_tests function instead of a test_suite
function. (a forthcoming patch will provide many examples on how to
implement this).
(Vincent Ladeuil)
* selftest --load-list now does some sanity checks regarding duplicate test
IDs and tests present in the list but not found in the actual test suite.
(Vincent Ladeuil)
* Slightly more concise format for the selftest progress bar, so there's
more space to show the test name. (Martin Pool) ::
* The test suite takes much less memory to run, and is a bit faster. This
is done by clearing most attributes of TestCases after running them, if
they succeeded. (Andrew Bennetts)
INTERNALS:
* Added ``_build_
* Added basic infrastructure for automatic plugin suggestion.
(Martin Albisetti)
* If a ``LockableFiles`` object is not explicitly unlocked (for example
because of a missing ``try/finally`` block, it will give a warning but
not automatically unlock itself. (Previously they did.) This
sometimes caused knock-on errors if for example the network connection
had already failed, and should not be relied upon by code.
(Martin Pool, #109520)
* ``make dist`` target to build a release tarball, and also

* The ``read_
classes will now raise ``UnknownSmartM
callers don't need to try distinguish unknown request errors from other
errors. (Andrew Bennetts)
* ``set_make_
