bzr 0.12rc1 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)
* New connection: ``bzr+http://`` which supports tunnelling the
smart protocol over an HTTP connection. If writing is enabled on
the bzr server, then you can write over the http connection.
(Andrew Bennetts)
* ``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,
#63360, #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)
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)
