bzr 2.0rc1
##########
:Codename: no worries
:2.0rc1: 2009-08-26
This release of Bazaar makes 2a 'brisbane-core' format the
default. Most of the work in this release now focuses on bug
fixes and stabilization, covering both 2a and previous formats.
The Bazaar team decided that 2.0 will be a long-term supported
release, with bugfix-only releases based on it continuing for at
least six months or until the following stable release (we said
that previously, but that's worth repeating).
Compatibility Breaks
********************
* The default format for bzr is now ``2a``. This format brings many
significant performance and size improvements. bzr can pull from
any existing repository into a ``2a`` one, but can only transfer
into ``rich-root`` repositories from ``2a``. The Upgrade guide
has more information about this change. (Robert Collins)
* On Windows auto-detection of Putty's plink.exe is disabled.
Default SSH client for Windows is paramiko. User still can force
usage of plink if explicitly set environment variable BZR_SSH=plink.
(#414743, Alexander Belchenko)
New Features
************
* ``bzr branch --switch`` can now switch the checkout in the current directory
to the newly created branch. (Lukáš Lalinský)
Bug Fixes
*********
* Further tweaks to handling of ``bzr add`` messages about ignored files.
(Jason Spashett, #76616)
* Fetches were being requested in 'groupcompress' order, but weren't
recombining the groups. Thus they would 'fragment' to get the correct
order, but not 'recombine' to actually benefit from it. Until we get
recombining to work, switching to 'unordered' fetches avoids the
fragmentation. (John Arbash Meinel, #402645)
* Fix a pycurl related test failure on karmic by recognizing an error
raised by newer versions of pycurl.
(Vincent Ladeuil, #306264)
* Fix a test failure on karmic by making a locale test more robust.
(Vincent Ladeuil, #413514)
* Fix IndexError printing CannotBindAddress errors.
(Martin Pool, #286871)
* Fix "Revision ... not present" errors when upgrading stacked branches,
or when doing fetches from a stacked source to a stacked target.
(Andrew Bennetts, #399140)
* ``bzr branch`` of 2a repositories over HTTP is much faster. bzr now
batches together small fetches from 2a repositories, rather than
fetching only a few hundred bytes at a time.
(Andrew Bennetts, #402657)
Improvements
************
* A better description of the platform is shown in crash tracebacks, ``bzr
--version`` and ``bzr selftest``.
(Martin Pool, #409137)
* bzr can now (again) capture crash data through the apport library,
so that a single human-readable file can be attached to bug reports.
This can be disabled by using ``-Dno_apport`` on the command line, or by
putting ``no_apport`` into the ``debug_flags`` section of
``bazaar.conf``.
(Martin Pool, Robert Collins, #389328)
* ``bzr push`` locally on windows will no longer give a locking error with
dirstate based formats. (Robert Collins)
* ``bzr shelve`` and ``bzr unshelve`` now work on windows.
(Robert Collins, #305006)
* Commit of specific files no longer prevents using the the iter_changes
codepath. On 2a repositories, commit of specific files should now be as
fast, or slightly faster, than a full commit. (Robert Collins)
* The internal core code that handles specific file operations like
``bzr st FILENAME`` or ``bzr commit FILENAME`` has been changed to
include the parent directories if they have altered, and when a
directory stops being a directory its children are always included. This
fixes a number of causes for ``InconsistentDelta`` errors, and permits
faster commit of specific paths. (Robert Collins, #347649)
Documentation
*************
* New developer documentation for content filtering.
(Martin Pool)
API Changes
***********
* ``bzrlib.shelf_ui`` has had the ``from_args`` convenience methods of its
classes changed to manage lock lifetime of the trees they open in a way
consistent with reader-exclusive locks. (Robert Collins, #305006)
