External Compatibility Breaks
*****************************
(none)
Improvements
************
* A redundant parent inventories calculation was removed from
``fetch.py``, as ``Repository.insert_stream`` already reports any
missing inventories. This removes at least one network roundtrip when
pushing to a stacked branch. (Andrew Bennetts)
* ``ControlDir.sprout`` no longer opens the target repository more than
once. This avoids some unnecessary IO, and removes a network roundtrip
when doing ``bzr branch`` to a smart server URL. (Andrew Bennetts)
* ``bzr modified`` now read-locks the working tree (and branch and
repository) just once. (Andrew Bennetts)
* ``bzr resolve`` now accepts ``--take-this`` and ``--take-other`` actions
for text conflicts. This *replace* the whole file with the content
designated by the action. This will *ignore* all differences that would
have been merge cleanly otherwise. (Vincent Ladeuil, #638451)
* ``bzr tags``'s "sort" argument now allows registering custom sort
methods using the ``bzrlib.tag.tag_sort_methods`` registry.
(Jelmer Vernooij, #701244)
* ``bt.test_http`` was breaking ``os.environ`` by erasing the values saved by
``TestCase`` leading to ``bt.test_import_tariff`` failures.
(Vincent Ladeuil, #690563)
* ``upgrade`` now upgrades dependent branches when a shared repository is
specified. It also supports new options: ``--dry-run`` for showing what
will happen and ``--clean`` to remove the backup directory on successful
completion. (Ian Clatworthy, Matthew Fuller, #89830, #374734, #422450)
Bug Fixes
*********
.. Fixes for situations where bzr would previously crash or give incorrect
or undesirable results.
* Avoid leaking SSH subprocess communication socket into unrelated child
processes, which could cause bzr to hang on exit. (Max Bowsher, #696285)
* ``bzr break-lock`` on a corrupted lock file works correctly, rather than
raising a PermissionDenied error. We were accidentally holding open the
file we were trying to delete. (John Arbash Meinel, #659978)
* ``bzr update`` in a checkout of a readonly branch works again, without
trying to set the tags in the master branch. This had been broken by the
bug fix for bug #603395. (John Arbash Meinel, #701212)
* Per-transport tests now prefer to use ``Transport.get_bytes()`` rather
than ``Transport.get().read()``. The SFTP code uses an async message to
close the file handle if you let the handle die from refcounting, while
it uses a synchronous message if you close it directly. This should help
prevent random test suite failures from race conditions.
(John Arbash Meinel, #681047)
* Stop using ``bzrlib.tuned_gzip.GzipFile``. It is incompatible with
python-2.7 and was only used for Knit format repositories, which haven't
been recommended since 2007. The file itself will be removed in the next
release. (John Arbash Meinel)
* The BZR_COLUMNS environment variable can be set to 0 to indicate no
limitation on the width of the terminal. (Neil Martinsen-Burrell, #675652)
* Treat WSAECONNABORTED the same as WSAECONNRESET for the purposes of
considering a smart data stream as being interrupted. This fixes a
failure in the windows test suite, that was trying to ensure we cleanly
handled a server disconnect. (John Arbash Meinel, #581311, #686587)
* Unshelving changes that occur in a now-unversioned directory now restore
the directory properly rather than crashing.
(John Arbash Meinel, #389674)
* You are now able to commit directly to a stacked branch. Any needed
parent inventories will be filled in as part of the commit process.
(John Arbash Meinel, #375013)
Documentation
*************
* Better document the rules to update the bzr freshmeat page when
doing a release. (Vincent Ladeuil, #690515)
API Changes
***********
* ``Branch.sprout``, ``BranchFormat.initalize`` and
``ControlDir.create_branch`` now take an optional ``repository`` keyword
argument, and ``BranchFormat.open`` now takes an optional
``found_repository`` keyword argument. These provide the repository
object for new branch object to use (for cases when the caller has
already opened that repository). Implementations of these APIs will
need to be updated to accept these arguments. (Andrew Bennetts)
* ``bzrlib.tuned_gzip.GzipFile`` is now deprecated and will be removed in
the bzr-2.4 series. Code that was using it can just use the python
stdlib ``gzip.GzipFile``. (John Arbash Meinel)
Testing
*******
* ``bzrlib.tests`` defines ``isolated_environ`` with the definitions of all
the environment variables the tests should care about. It also defines
``override_os_environ`` and ``restore_os_environ`` to properly implement
isolation from ``os.environ`` for tests. ``bzrlib.tests`` now defines a
``DocTestSuite`` class using this facility for all ``bzrlib``
doctests. (Vincent Ladeuil, #321320)
* Catch exceptions related to bug #637821 during test cleanup to avoid
spurious failures. (Vincent Ladeuil, #686008).
* Check sphinx compatibility for tests requiring older sphinx versions.
(Vincent Ladeuil, #688072)
* ``test_onto_transport`` in the Launchpad plugin can now run with Python
2.7. (Vincent Ladeuil, #654733)
* ``TestCase._captureVar`` and ``TestCase._old_env`` have been deleted due to
bug #690563. Test writers are encouraged to use ``TestCase.overrideEnv``
instead. (Vincent Ladeuil)
* ``TestDebuntuExpansions`` was escaping the test isolation by calling the
wrong base class ``setUp``. (Vincent Ladeuil, #684662)
