bzr 2.2.1 released !

[Vincent Ladeuil]

The Bazaar team is happy to announce availability of a new
release of the bzr adaptive version control system.
Bazaar is part of the GNU system <http://gnu.org/>.

This is a bugfix release which also includes bugfixes from 2.0.6 and
2.1.3. None are critical, but upgrading is recommended for all users on
earlier 2.2 releases.

Thanks to everyone who contributed patches, suggestions, and
feedback.

Bazaar is now available for download from

  https://launchpad.net/bzr/2.2/2.2.1/

as a source tarball. Packages are already available for Ubuntu, FreeBSD
and others. Installers are available for OSX, windows installers should
be available Really Soon Now (watch the url above where they should pop
up as soon as they become available).

bzr 2.2.1

:2.2.1: 2010-09-17

This is a bugfix release which also includes bugfixes from 2.0.6 and
2.1.3. None are critical, but upgrading is recommended for all users on
earlier 2.2 releases.

Bug Fixes
*********

* Additional merges after an unrelated branch has been merged with its
  history no longer crash when deleted files are involved.
  (Vincent Ladeuil, John Arbash Meinel, #375898)

* ``bzr add SYMLINK/FILE`` now works properly when the symlink points to a
  previously-unversioned directory within the tree: the directory is
  marked versioned too.
  (Martin Pool, #192859)

* ``bzr commit SYMLINK`` now works, rather than trying to commit the
  target of the symlink.
  (Martin Pool, John Arbash Meinel, #128562)

* ``bzr upgrade`` now creates the ``backup.bzr`` directory with the same
  permissions as ``.bzr`` directory on a POSIX OS.
  (Parth Malwankar, #262450)

* CommitBuilder now uses the committer instead of _config.username to generate
  the revision-id. (Aaron Bentley, #614404)

* Configuration files in ``${BZR_HOME}`` are now written in an atomic
  way which should help avoid problems with concurrent writers.
  (Vincent Ladeuil, #525571)

* Cope with Microsoft FTP server that returns reply '250 Directory
  created' when mkdir succeeds. (Martin Pool, #224373)

* Don't traceback trying to unversion children files of an already
  unversioned directory. (Vincent Ladeuil, #494221)

* Don't traceback when a lockdir's ``held/info`` file is corrupt (e.g.
  contains only NUL bytes). Instead warn the user, and allow ``bzr
  break-lock`` to remove it. (Andrew Bennetts, #619872)

* Fix ``AttributeError on parent.children`` when adding a file under a
  directory that was a symlink in the previous commit.
  (Martin Pool, #192859)

* Fix ``AttributeError: 'NoneType' object has no attribute 'close'`` in
  ``_close_ssh_proc`` when using ``bzr+ssh://``. This was causing
  connections to pre-1.6 bzr+ssh servers to fail, and causing warnings on
  stderr in some other circumstances. (Andrew Bennetts, #633745)

* Only call ``setlocale`` in the bzr startup script on posix systems. This
  avoids an issue with the newer windows C runtimes used by Python 2.6 and
  later which can mangle bytestrings printed to the console.
  (Martin [gz], #631350)

* Prevent ``CHKMap.apply_delta`` from generating non-canonical CHK maps,
  which can result in "missing referenced chk root keys" errors when
  fetching from repositories with affected revisions.
  (Andrew Bennetts, #522637)

* Raise ValueError instead of a string exception.
  (John Arbash Meinel, #586926)

* Reduce peak memory by one copy of compressed text.
  (John Arbash Meinel, #566940)

* Repositories accessed via a smart server now reject being stacked on a
  repository in an incompatible format, as is the case when accessing them
  via other methods. This was causing fetches from those repositories via
  a smart server (e.g. using ``bzr branch``) to receive invalid data.
  (Andrew Bennetts, #562380)

* Selftest with versions of subunit that support ``stopTestRun`` will no longer
  error. This error was caused by 2.0 not being updated when upstream
  python merged the end of run patch, which chose ``stopTestRun`` rather than
  ``done``. (Robert Collins, #571437)

* Stop ``AttributeError: 'module' object has no attribute 'ElementTree'``
  being thrown from ``xml_serializer`` on certain cElementTree setups.
  (Martin [gz], #254278)

* Upgrading or fetching from a non-rich-root repository to a rich-root
  repository (e.g. from pack-0.92 to 2a) no longer fails with
  ``'Inter1and2Helper' object has no attribute 'source_repo'``. This was
  a regression from Bazaar 2.1. (Andrew Bennetts, #636930)

* 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)

Documentation
*************

* Fix a lot of references in the docs to the old http://bazaar-vcs.org to
  the new http://bazaar.canonical.com or http://wiki.bazaar.canonical.com
  (John Arbash Meinel, #617503)

Internals
*********

* Remove used and broken code path in ``BranchInitHookParams.__repr__``.
  (Andrew Bennetts)

Testing
*******

* ``build_tree_contents`` can create symlinks.
  (Martin Pool, John Arbash Meinel)

* Tracebacks from a parameterized test are no longer reported against every
  parameterization of that test. This was done by adding a hack to
  ``bzrlib.tests.clone_test`` so that it no longer causes
  testtools.TestCase instances to share a details dict.
  (Andrew Bennetts, #625574)
