:Codename: Do run run
:2.1.3: 2010-09-17

The third release in our 2.1 series addresses several user-inconvenience bugs
(and includes the fixes done in 2.0.6). None are critical, but upgrading is
recommended for all users on earlier 2.1 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)

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

* 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)

* 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)

* 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)

Testing
*******

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