Fix two more leaking tmp dirs, by reworking TransformPreview lock handling.

* bzrlib/tests/test_transform.py:
(TestTransformMerge): Revert previous patch and cleanly call
preview.finalize now that we can.

* bzrlib/tests/test_merge.py:
(TestMerge.test_make_preview_transform): Catch TransformPreview
leak.

* bzrlib/builtins.py:
(cmd_merge._do_preview): Finalize the TransformPreview or the
limbodir will stay in /tmp.

* bzrlib/transform.py:
(TreeTransformBase.__init__): Create the _deletiondir since it's
reffered to by finalize.
(TreeTransformBase.finalize): Delete the dir only if _deletiondir
is set.
(TreeTransform.__init__): Use a temp var for deletiondir and set
the attribute after the base class __init__ has been called.
(TransformPreview.__init__): Read locks the tree since finalize
wants to unlock it (as suggested by Aaron).

Revision Properties
 
2
===================
 
3
 
 
4
Bazaar repositories support setting of a key/value pairs for each revision.
 
5
Applications can use these properties to store additional information
 
6
about the revision.

Usage
 
9
-----
 
10
 
 
11
In general, revision properties are set by passing keyword argument
 
12
``revprops`` to method ``MutableTree.commit``. For example::
 
13
 
 
14
 properties = {}
 
15
 properties['my-property'] = 'test'
 
16
 tree.commit(message, revprops=properties)
 
17
 
 
18
Properties can be retrieved via the attribute ``properties`` of
 
19
instances of the class ``Revision``::
 
20
 
 
21
 if 'my-property' in revision.properties:
 
22
     my_property = revision.properties['my-property']
 
23
     ...

Well-known properties
 
26
---------------------
 
27
 
 
28
At the moment, three standardized revision properties are recognized and used
 
29
by bzrlib:
 
30
 
 
31
 * ``author`` - Author of the change. This value is in the same format as
 
32
   the committer-id. This property can be set by passing keyword argument
 
33
   ``author`` to function ``MutableTree.commit``.
 
34
 * ``branch-nick`` - Nickname of the branch. It's either the directory name
 
35
   or manually set by ``bzr nick``. The value is set automatically in
 
36
   ``MutableTree.commit``.
 
37
 * ``bugs`` - A list of bug URLs and their statuses. The list is separated
 
38
   by the new-line character (\n) and each entry is in format
 
39
   '<URL> <status>'. Currently, bzrlib uses only status 'fixed'. See
 
40
   `Bug Trackers`_ for more details about using this feature.
