bzr 1.15
########
:1.15rc1: 2009-05-16
:1.15: 2009-05-22
:1.15.1: 2009-06-09

The smart server will no longer raise 'NoSuchRevision' when streaming content
with a size mismatch in a reconstructed graph search. New command ``bzr
dpush``. Plugins can now define their own annotation tie-breaker when two
revisions introduce the exact same line.

Changes from 1.15.1 to 1.15.2
*****************************

* Use zdll on Windows to build ``_chk_map_pyx`` extension.
  (Alexander Belchenko)

Changes from 1.15final to 1.15.1
*********************************

* Translate errors received from a smart server in response to a
  ``BzrDirFormat.initialize`` or ``BzrDirFormat.initialize_ex`` request.
  This was causing tracebacks even for mundane errors like
  ``PermissionDenied``.  (Andrew Bennetts, #381329)

Changes from 1.15rc1 to 1.15final
*********************************

* No changes

Compatibility Breaks
********************

* ``bzr ls`` is no longer recursive by default. To recurse, use the
  new ``-R`` option. The old ``--non-recursive`` option has been removed.
  If you alias ``ls`` to ``ls -R``, you can disable recursion using
  ``--no-recursive`` instead.  (Ian Clatworthy)

New Features
************

* New command ``bzr dpush`` that can push changes to foreign 
  branches (svn, git) without setting custom bzr-specific metadata.
  (Jelmer Vernooij)

* The new development format ``--development6-rich-root`` now supports
  stacking. We chose not to use a new format marker, since old clients
  will just fail to open stacked branches, the same as if we used a new
  format flag. (John Arbash Meinel, #373455)

* Plugins can now define their own annotation tie-breaker when two revisions
  introduce the exact same line. See ``bzrlib.annotate._break_annotation_tie``
  Be aware though that this is temporary, private (as indicated by the leading
  '_') and a first step to address the problem. (Vincent Ladeuil, #348459)

* New command ``bzr dpush`` that can push changes to foreign 
  branches (svn, git) without setting custom bzr-specific metadata.
  (Jelmer Vernooij)

* ``bzr send`` will now check the ``child_submit_format`` setting in
  the submit branch to determine what format to use, if none was 
  specified on the command-line.  (Jelmer Vernooij)

Improvements
************

* -Dhpss output now includes the number of VFS calls made to the remote
  server. (Jonathan Lange)

* ``--coverage`` works for code running in threads too.
  (Andrew Bennets, Vincent Ladeuil)

* ``bzr pull`` now has a ``--local`` option to only make changes to the
  local branch, and not the bound master branch.
  (Gary van der Merwe, #194716)

* ``bzr rm *`` is now as fast as ``bzr rm * --keep``. (Johan Walles, #180116)

Bug Fixes
*********

* Adding now works properly when path contains a symbolic link.
  (Geoff Bache, #183831)

* An error is now raised for unknown eol values. (Brian de Alwis, #358199)

* ``bzr merge --weave`` will now generate a conflict if one side deletes a
  line, and the other side modifies the line. (John Arbash Meinel, #328171)

* ``bzr reconfigure --standalone`` no longer raises IncompatibleRepositories.
  (Martin von Gagern, #248932)

* ``bzr send`` works to send emails again using MAPI.
  (Neil Martinsen-Burrell, #346998)

* Check for missing parent inventories in StreamSink.  This prevents
  incomplete stacked branches being created by 1.13 bzr:// and
  bzr+ssh:// clients (which have bug #354036).  Instead, the server now
  causes those clients to send the missing records.  (Andrew Bennetts)

* Correctly handle HTTP servers proposing multiple authentication schemes.
  (Vincent Ladeuil, #366107)

* End-Of-Line content filters are now loaded correctly.
  (Ian Clatworthy, Brian de Alwis, #355280)

* Fix a bug in the pure-python ``GroupCompress`` code when handling copies
  longer than 64KiB. (John Arbash Meinel, #364900)

* Fix TypeError in running ``bzr break-lock`` on some URLs.
  (Alexander Belchenko, Martin Pool, #365891)

* Non-recursive ``bzr ls`` now works properly when a path is specified.
  (Jelmer Vernooij, #357863)

* SSH usernames (defined in ~/.ssh/config) are honoured for bzr+ssh connections.
  (Vincent Ladeuil, #367726)

* Several bugs related to unicode symlinks have been fixed and the test suite
  enhanced to better catch regressions for them. (Vincent Ladeuil)

* The smart server will no longer raise 'NoSuchRevision' when streaming
  content with a size mismatch in a reconstructed graph search: it assumes
  that the client will make sure it is happy with what it got, and this
  sort of mismatch is normal for stacked environments.
  bzr 1.13.0/1 will stream from unstacked branches only - in that case not
  getting all the content expected would be a bug. However the graph
  search is how we figured out what we wanted, so a mismatch is both odd
  and unrecoverable without starting over, and starting over will end up
  with the same data as if we just permitted the mismatch. If data is
  gc'd, doing a new search will find only the truncated data, so sending
  only the truncated data seems reasonable. bzr versions newer than this
  will stream from stacked branches and check the stream to find missing
  content in the stacked-on branch, and thus will handle the situation
  implicitly.  (Robert Collins, #360791)

* Upgrading to, or fetching into a 'rich-root' format will now correctly
  set the root data the same way that reconcile does.
  (Robert Collins, #368921)

* Using unicode Windows API to obtain command-line arguments.
  (Alexander Belchenko, #375934)

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

API Changes
***********

* ``InterPackRepo.fetch`` and ``RepoFetcher`` now raise ``NoSuchRevision``
  instead of ``InstallFailed`` when they detect a missing revision.
  ``InstallFailed`` itself has been deleted. (Jonathan Lange)

* Not passing arguments to ``bzrlib.commands.main()`` will now grab the
  arguments from ``osutils.get_unicode_argv()`` which has proper support
  for unicode arguments on windows. Further, the supplied arguments are now 
  required to be unicode strings, rather than user_encoded strings.
  (Alexander Belchenko)

Internals
*********

* ``bzrlib.branch.Branch.set_parent`` is now present on the base branch
  class and will call ``_set_parent_location`` after doing unicode 
  encoding. (Robert Collins)

* ``bzrlib.remote.RemoteBranch._set_parent_location`` will use a new verb
  ``Branch.set_parent_location`` removing further VFS operations.
  (Robert Collins)

* ``bzrlib.bzrdir.BzrDir._get_config`` now returns a ``TransportConfig``
  or similar when the dir supports configuration settings. The base class
  defaults to None. There is a matching new server verb
  ``BzrDir.get-config_file`` to reduce roundtrips for getting BzrDir
  configuration. (Robert Collins)

* ``bzrlib.tests.ExtendedTestResult`` has new methods ``startTests``
  called before the first test is started, ``done`` called after the last
  test completes, and a new parameter ``strict``. (Robert Collins)

* ``-Dhpss`` when passed to bzr will cause a backtrace to be printed when
  VFS operations are started on a smart server repository. This should not
  occur on regular push and pull operations, and is a key indicator for
  performance regressions. (Robert Collins)

* ``-Dlock`` when passed to the selftest (e.g. ``bzr -Dlock selftest``) will
  cause mismatched physical locks to cause test errors rather than just
  reporting to the screen. (Robert Collins)

* -Dprogress will cause pdb to start up if a progress view jumps
  backwards. (Robert Collins)

* Fallback ``CredentialStore`` instances registered with ``fallback=True``
  are now be able to provide credentials if obtaining credentials 
  via ~/.bazaar/authentication.conf fails. (Jelmer Vernooij, 
  Vincent Ladeuil, #321918)

* New hook ``Lock.lock_broken`` which runs when a lock is
  broken. This is mainly for testing that lock/unlock are
  balanced in tests. (Vincent Ladeuil)

* New MergeDirective hook 'merge_request_body' allows hooks to supply or
  alter a body for the message produced by ``bzr send``.

* New smart server verb ``BzrDir.initialize_ex`` which implements a
  refactoring to the core of clone allowing less round trips on new
  branches. (Robert Collins)

* New method ``Tags.rename_revisions`` that can rename revision ids tags
  are pointing at. (Jelmer Vernooij)

* Updated the bundled ``ConfigObj`` library to 4.6.0 (Matt Nordhoff)

Testing
*******

* ``bzr selftest`` will now fail if lock/unlock are not correctly balanced in
  tests. Using ``-Dlock`` will turn the related failures into warnings.
  (Vincent Ladeuil, Robert Collins)
