Compatibility Breaks
********************
* An API break has been made to the lock_write method of ``Branch`` and
``Repository`` objects; they now return ``branch.BranchWriteLockResult``
and ``repository.RepositoryWriteLockResult`` objects. This makes
changing the API in future easier and permits some cleaner calling code.
The lock_read method has also changed from having no defined return
value to returning ``LogicalLockResult`` objects.
(Robert Collins)
* ``bzr`` does not try to guess the username as ``username@hostname``
and requires it to be explictly set. This can be set using ``bzr
whoami``.
(Parth Malwankar, #549310)
* ``bzrlib.commands.Command`` will now raise ValueError during
construction if there is no __doc__ set. (Note, this will be reverted in
2.2b4) (Robert Collins)
New Features
************
* ``bzr commit`` accepts ``-p`` (for "patch") as a shorter name for
``--show-diff``.
(Parth Malwankar, #571467)
* ``bzr ignore`` now supports a ``--default-rules`` option that displays
the default ignore rules used by bzr. The flag ``--old-default-rules``
is no longer supported by ``ignore``.
(Parth Malwankar, #538703)
* ``bzr pack`` now supports a ``--clean-obsolete-packs`` option that
can save disk space by deleting obsolete pack files created during the
pack operation.
(Parth Malwankar, #304320)
* New command line option ``--authors`` to ``bzr log`` allows users to
select which of the apparent authors and committer should be
included in the log. Defaults depend on format. (Martin von Gagern, #513322)
* Support ``--directory`` option for a number of additional commands:
added, annotate, bind, cat, cat-revision, clean-tree, deleted,
export, ignore, ignored, lookup-revision, ls, modified, nick,
re-sign, unbind, unknowns.
(Martin von Gagern, #527878)
* The bash_completion plugin from the bzr-bash-completion project has
been merged into the tree. It provides a bash-completion command and
replaces the outdated ``contrib/bash/bzr`` script with a version
using the plugin. (Martin von Gagern, #560030)
Bug Fixes
*********
* Alias information shown by ``bzr help`` is now accurate. This
was showing an internal object name for some plugin aliases.
(Parth Malwankar, #584650)
* ``.bazaar``, ``.bazaar/bazaar.conf`` and ``.bzr.log`` inherit user and
group ownership from the containing directory. This allow bzr to work
better with sudo.
(Martin <email address hidden>, Parth Malwankar, #376388)
* ``bzr clean-tree`` should not delete nested bzrdirs. Required for proper
support of bzr-externals and scmproj plugins.
(Alexander Belchenko, bug #572098)
* ``bzr ignore`` will no longer add duplicate patterns to .bzrignore.
(Gordon Tyler, #572092)
* ``bzr log --exclude-common-ancestry -r X..Y`` displays the revisions that
are part of Y ancestry but not part of X ancestry (aka the graph
difference).
(Vincent Ladeuil, #320119)
* ``bzr lp-propose`` which was switched to use production Launchpad API
servers a few commits ago has been reverted to use edge: there is a
problem with using production which isn't trivially obvious, so we've
filed a bug to track it, and until thats fixed will be using edge.
(Robert Collins, #583667)
* ``bzr rm`` should not refuse to delete directories which contained a file
which has been moved elsewhere in the tree after the previous commit.
(Marius Kruger, Daniel Watkins, #129880)
* ``bzr selftest --parallel=fork`` wait for its children avoiding zombies.
(Vincent Ladeuil, #566670)
* ``bzr selftest`` should not use ui.note() since it's not unicode safe.
(Vincent Ladeuil, #563997)
* CommitBuilder refuses to create revisions whose trees have no root.
(Aaron Bentley)
* Do not register a SIGWINCH signal handler, instead just poll for the
terminal width as needed. This avoids the "Interrupted System Call"
problems that occur on POSIX with all currently released versions of
Python.
(Andrew Bennetts, #583941)
* Don't mention --no-strict when we just issue the warning about unclean trees.
(Vincent Ladeuil, #401599)
* Fixed ``AssertionError`` when accessing smart servers running Bazaar
versions before 1.6.
(Andrew Bennetts, #528041)
* Improved progress bar for fetch (2a format only). Bazaar now shows an
estimate of the number of records to be fetched vs actually fetched.
(Parth Malwankar, #374740, #538868)
* Reduce peak memory by one copy of compressed text.
(John Arbash Meinel, #566940)
* ``RemoteBranch.lock_write`` raises ``ReadOnlyError`` if called during a
read lock, rather than causing an ``AttributeError``.
(Andrew Bennetts, Данило Шеган, #582781)
* Selftest was failing with testtools 0.9.3, which caused an
AssertionError raised from a cleanUp to be reported as a Failure, not an
Error, breaking on of our test hygiene tests.
(Robert Collins, Vincent Ladeuil).
* ``set_user_option`` with a dict on remote branches no longer fails with
an AttributeError. There is a new ``Branch.set_config_option_dict`` RPC
to support this efficiently.
(Andrew Bennetts, #430382)
* Show the filenames when a file rename fails so that the error will be
more comprehensible.
(Martin Pool, #491763)
* Support Pyrex 0.9.9, required changing how we handle exceptions in Pyrex.
(John Arbash Meinel, #582656)
* Unicode characters in aliases are now handled correctly and do not cause
UnicodeEncodeError exception. (Parth Malwankar, #529930)
* Unicode commit messages that are the same as a file name no longer cause
UnicodeEncodeError. ``ui.text.show_warning`` now handles unicode
messages.
(Parth Malwankar, #563646)
* Using bzr with `lp:` urls behind an http proxy should work.
(Robert Collins, #558343)
* When passing a file to ``UTF8DirReader`` make sure to close the current
directory file handle after the chdir fails. Otherwise when passing many
filenames into a command line ``bzr status`` we would leak descriptors.
(John Arbash Meinel, #583486)
Improvements
************
* ``append_revisions_only`` will now be interpreted as a boolean and a
warning emitted if illegal values are used. Note that for projects
that needs to maintain compatibility with previsous bzr versions,
only 'True' and 'False' strings must be used (previous versions of
bzr will interpret all strings differing from 'True'
(case-sensitive) as false.
(Brian de Alwis, Vincent Ladeuil)
* ``bzr ls`` now supports short options for existing long options.
``-k/--kind``, ``-i/--ignored``, ``-u/--unknown`` and ``-0/--null``.
(Parth Malwankar, #181124)
* ``Config.get_user_option_as_bool`` will now warn if a value cannot
be interpreted as a boolean.
(Vincent Ladeuil)
* The all-in-one Windows installer will now be built with docstrings stripped
from the library zip, reducing the size and slightly improving cold startup
time. Bundled plugins are unchanged for the moment, but if adding other new
plugins to an all-in-one installation, ensure they are compiled and
installed with -O1 or help may not work. (Martin [gz])
Documentation
*************
API Changes
***********
* Added ``bzrlib.merge.PerFileMerger``, a more convenient way to write
some kinds of ``merge_file_content`` hook functions.
(Andrew Bennetts)
* `BzrDir`, `Branch`, `Repository` and `WorkingTree` now all support `user_url`,
`user_transport`, `control_url` and `control_transport` members pointing
respectively to the directory containing the ``.bzr`` control directory,
and to the directory within ``.bzr`` used for the particular component.
All of them inherit from `ControlComponent` which provides default
implementations.
(Martin Pool)
* Lock methods on ``Tree``, ``Branch`` and ``Repository`` are now
expected to return an object which can be used to unlock them. This reduces
duplicate code when using cleanups. The previous 'tokens's returned by
``Branch.lock_write`` and ``Repository.lock_write`` are now attributes
on the result of the lock_write. ``repository.RepositoryWriteLockResult``
and ``branch.BranchWriteLockResult`` document this. (Robert Collins)
* ``Repository.refresh_data`` may now be called in a write group on
pack-based repositories. Older repositories will still raise an error
in this case. Subclasses of ``Repository`` can still override
``Repository._refresh_data``, but are now responsible for raising
``bzrlib.repository.IsInWriteGroupError`` if they do not support
``refresh_data`` during a write group.
(Andrew Bennetts, #574236)
Internals
*********
* ``chk_map._bytes_to_text_key`` is now an optimized function to extract
the (file-id, revision-id) key from a CHKInventory entry. This can
potentially shave 5-10% time off during a large fetch. Related to bug
#562666. (John Arbash Meinel)
* ``log._get_info_for_log_files`` now takes an add_cleanup callable.
(Robert Collins)
* ``_remember_remote_is_before`` no longer raises AssertionError when
suboptimal network behaviour is noticed; instead it just mutters to the
log file (and warns the user if they have set the ``hpss`` debug flag).
This was causing unnecessary aborts for performance bugs that are minor
at worst.
(Andrew Bennetts, #528041)
* Permit bzr to run under ``python -OO`` which reduces the size of bytecode
files loaded from disk. To ensure docstrings needed for help are never
stripped, the prefix ``__doc__ =`` should now be used.
(Martin <email address hidden>)
* No longer require zlib headers to build extensions, and remove the need
for seperate copy of zlib library on windows.
(John Arbash Meinel, Martin <email address hidden>, #66923)
Testing
*******
* Added ``bzrlib.tests.matchers`` as a place to put matchers, along with
our first in-tree matcher. See the module docstring for details.
(Robert Collins)
* ``bzr selftest --parallel=subprocess`` now works correctly on win32.
(Gordon Tyler, #551332)
* Workaround ``Crypto.Random`` check leading to spurious test
failures on Lucid, FreeBSD and gentoo.
(Vincent Ladeuil, #528436)
* New class ``ExecutableFeature`` for checking the availability of
executables on the ``PATH``. Migrated from bash_completion plugin.
(Martin von Gagern)
