bzr 0.12

########

:Released:  2006-10-30

Internals

*********

* Clean up ``bzr selftest --benchmark bundle`` to correct an import,

  and remove benchmarks that take longer than 10min to run.

  (John Arbash Meinel)

bzr 0.12rc1

###########

:Released:  2006-10-23

Improvements

************

* ``bzr log`` now shows dotted-decimal revision numbers for all revisions,

  rather than just showing a decimal revision number for revisions on the

  mainline. These revision numbers are not yet accepted as input into bzr

  commands such as log, diff etc. (Robert Collins)

* revisions can now be specified using dotted-decimal revision numbers.

  For instance, ``bzr diff -r 1.2.1..1.2.3``. (Robert Collins)

* ``bzr help commands`` output is now shorter (Aaron Bentley)

* ``bzr`` now uses lazy importing to reduce the startup time. This has

  a moderate effect on lots of actions, especially ones that have

  little to do. For example ``bzr rocks`` time is down to 116ms from

  283ms. (John Arbash Meinel)

* New Registry class to provide name-to-object registry-like support,

  for example for schemes where plugins can register new classes to

  do certain tasks (e.g. log formatters). Also provides lazy registration

  to allow modules to be loaded on request.

  (John Arbash Meinel, Adeodato Simó)

API Incompatability

*******************

* LogFormatter subclasses show now expect the 'revno' parameter to

  show() to be a string rather than an int. (Robert Collins)

Internals

*********

* ``TestCase.run_bzr``, ``run_bzr_captured``, and ``run_bzr_subprocess``

  can take a ``working_dir='foo'`` parameter, which will change directory

  for the command. (John Arbash Meinel)

* ``bzrlib.lazy_regex.lazy_compile`` can be used to create a proxy

  around a regex, which defers compilation until first use.

  (John Arbash Meinel)

* ``TestCase.run_bzr_subprocess`` defaults to supplying the

  ``--no-plugins`` parameter to ensure test reproducability, and avoid

  problems with system-wide installed plugins. (John Arbash Meinel)

* Unique tree root ids are now supported. Newly created trees still

  use the common root id for compatibility with bzr versions before 0.12.

  (Aaron Bentley)

* ``WorkingTree.set_root_id(None)`` is now deprecated. Please

  pass in ``inventory.ROOT_ID`` if you want the default root id value.

  (Robert Collins, John Arbash Meinel)

* New method ``WorkingTree.flush()`` which will write the current memory

  inventory out to disk. At the same time, ``read_working_inventory`` will

  no longer trash the current tree inventory if it has been modified within

  the current lock, and the tree will now ``flush()`` automatically on

  ``unlock()``. ``WorkingTree.set_root_id()`` has been updated to take

  advantage of this functionality. (Robert Collins, John Arbash Meinel)

* ``bzrlib.tsort.merge_sorted`` now accepts ``generate_revnos``. This

  parameter will cause it to add another column to its output, which

  contains the dotted-decimal revno for each revision, as a tuple.

  (Robert Collins)

* ``LogFormatter.show_merge`` is deprecated in favour of

  ``LogFormatter.show_merge_revno``. (Robert Collins)

Bug Fixes

*********

* Avoid circular imports by creating a deprecated function for

  ``bzrlib.tree.RevisionTree``. Callers should have been using

  ``bzrlib.revisontree.RevisionTree`` anyway. (John Arbash Meinel,

  #66349)

* Don't use ``socket.MSG_WAITALL`` as it doesn't exist on all

  platforms. (Martin Pool, #66356)

* Don't require ``Content-Type`` in range responses. Assume they are a

  single range if ``Content-Type`` does not exist.

  (John Arbash Meinel, #62473)

* bzr branch/pull no longer complain about progress bar cleanup when

  interrupted during fetch.  (Aaron Bentley, #54000)

* ``WorkingTree.set_parent_trees()`` uses the trees to directly write

  the basis inventory, rather than going through the repository. This

  allows us to have 1 inventory read, and 2 inventory writes when

  committing a new tree. (John Arbash Meinel)

* When reverting, files that are not locally modified that do not exist

  in the target are deleted, not just unversioned (Aaron Bentley)

* When trying to acquire a lock, don't fail immediately. Instead, try

  a few times (up to 1 hour) before timing out. Also, report why the

  lock is unavailable (John Arbash Meinel, #43521, #49556)

* Leave HttpTransportBase daughter classes decides how they

  implement cloning. (Vincent Ladeuil, #61606)

* diff3 does not indicate conflicts on clean merge. (Aaron Bentley)

* If a commit fails, the commit message is stored in a file at the root of

  the tree for later commit. (Cheuksan Edward Wang, Stefan Metzmacher,

  #32054)

Testing

*******

* New test base class TestCaseWithMemoryTransport offers memory-only

  testing facilities: its not suitable for tests that need to mutate disk

  state, but most tests should not need that and should be converted to

  TestCaseWithMemoryTransport. (Robert Collins)

* ``TestCase.make_branch_and_memory_tree`` now takes a format

  option to set the BzrDir, Repository and Branch formats of the

  created objects. (Robert Collins, John Arbash Meinel)
