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.

Fedora Backported Bug Fixes
***************************

* Fix traceback with python-2.7's xmlrpclib
  (Toshio Kuratomi, #612096)

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)
