Bazaar Release Notes
####################
.. toctree::
:maxdepth: 1
bzr 2.5b1
#########
:2.5b1: NOT RELEASED YET
External Compatibility Breaks
*****************************
.. These may require users to change the way they use Bazaar.
New Features
************
.. New commands, options, etc that users may wish to try out.
* A ``from_unicode`` parameter can be specified when registering a config
option. This implements boolean and integer config options when the
provided ``bool_from_store`` and ``int_from_store`` are used.
(Vincent Ladeuil)
* A ``from_unicode`` parameter can be specified when registering a config
option. This implements boolean, integer and list config options when the
provided ``bool_from_store``, ``int_from_store`` and ``list_from_store``
are used for this parameter. (Vincent Ladeuil)
* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now
checks to see if the most recent published source package version for
that project is present in the branch tags. This should help developers
trust whether the packaging branch is up-to-date and can be used for new
changes. The level of verbosity is controlled by the config item
``launchpad.packaging_verbosity``. It can be set to one of
off
disable all checks
minimal
only display if the branch is out-of-date
short
also display single-line up-to-date and missing,
all
(default) display multi-line content for all states
(John Arbash Meinel, #609187, #812928)
* Add a config option gpg_signing_key for setting which GPG key should
be used to sign commits. Also default to using the gpg user identity
which matches user_email() as set by whoami. (Jonathan Riddell,
#68501)
* An ``invalid`` parameter can be specified when registering a config option
to decide what should be done when invalid values are
encountered. 'warning' and 'eeror' will respectively emit a warning and
ignore the value or errors out. (Vincent Ladeuil)
* bzr log -m now matches message, author, committer and bugs instead
of just matching the message. --message keeps its original meaning,
while --match-message, --match-author, --match-committer and
--match-bugs match each of those fields.
* ``bzr help configuration/<option>`` display the help for ``option`` for
all registered configuration options. (Vincent Ladeuil, #747050)
* Relative local paths can now be specified in URL syntax by using the
"file:" prefix. (Jelmer Vernooij)
Improvements
************
.. Improvements to existing commands, especially improved performance
or memory usage, or better results.
Bug Fixes
*********
.. Fixes for situations where bzr would previously crash or give incorrect
or undesirable results.
* A call to CHKInventory's filter-method will not result in a
DuplicateFileId error, if you move a subfolder and change a file in
that subfolder.
(Bastian Bowe, #809901)
* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
errors. (Vincent Ladeuil, #822571)
* Fix i18n use when no environment variables are set. (Jelmer Vernooij, #810701)
* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so
operations that use it, like merge, can now create trees without a root.
(Aaron Bentley)
Documentation
*************
.. Improved or updated documentation.
* Release instructions refreshed. (Vincent Ladeuil)
API Changes
***********
.. Changes that may require updates in plugins or other code that uses
bzrlib.
* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
(Jelmer Vernooij)
* New methods ``get_transport_from_path`` and ``get_transport_from_url``
have been added that only support opening from a path or a URL,
unlike ``get_transport``. (Jelmer Vernooij)
* New method ``Tree.get_file_verifier`` which allows tree implementations
to return non-sha1 checksums to verify files.
(Jelmer Vernooij, #720831)
* New method ``InterTree.file_content_matches`` which checks that
two files in different trees have the same contents.
(Jelmer Vernooij)
* New registry ``OptionRegistry`` specialized for configuration options.
(Vincent Ladeuil)
* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10.
(Vincent Ladeuil)
* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``,
``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in
2.10 and 2.2.0. (Vincent Ladeuil)
* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0.
* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``,
``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also
remove ``log.show_one_log`` which was never properly deprecated but wasn't
used and is easy to inline if needed. (Vincent Ladeuil)
* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error``
deprecated in 2.1.0. (Vincent Ladeuil)
* Remove ``TransportListRegistry.set_default_transport``, as the concept of
a default transport is currently unused. (Jelmer Vernooij)
* Remove ``UIFactory.warn_cross_format_fetch`` and
``UIFactory.warn_experimental_format_fetch`` in favor of
``UIFactory.show_user_warning``. (Jelmer Vernooij)
* There is a new class `ContentFilterTree` that provides a facade for
content filtering. The `filtered` parameter to `export` is deprecated
in favor of passing a filtered tree, and the specific exporter plugins
no longer support it.
(Martin Pool)
* ``Transport`` now has a ``_parsed_url`` attribute instead of
separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host``
and ``_path`` attributes. Proxies are provided for the moment but
may be removed in the future. (Jelmer Vernooij)
Internals
*********
.. Major internal changes, unlikely to be visible to users or plugin
developers, but interesting for bzr developers.
* New method ``ControlDir._get_selected_branch`` which returns the
colocated branch selected using path segment parameters.
(Jelmer Vernooij, #380871)
Testing
*******
.. Fixes and changes that are only relevant to bzr's test framework and
suite. This can include new facilities for writing tests, fixes to
spurious test failures and changes to the way things should be tested.
* `BranchBuilder.build_snapshot` now supports a "flush" action. This
cleanly and reliably allows tests using `BranchBuilder` to construct
branches that e.g. rename files out of a directory and unversion that
directory in the same revision. Previously some changes were impossible
due to the order that `build_snapshot` performs its actions.
(Andrew Bennetts)
* Don't require ``os.fdatasync`` to be defined on all supported OSes
(BSD-based OSes don't define it). (Vincent Ladeuil, #822649)
* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)
* ``LockDir`` can now be run when the local hostname is ``localhost``.
(Jelmer Vernooij, #825994)
* ``ModuleAvailableFeature`` won't try to import already imported modules,
allowing it to be used for modules with side-effects.
(Vincent Ladeuil, #712474)
* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now
just compares the bytes in the dirstate file to its pristine state,
rather than opening the WorkingTree and calling ``last_revision()``.
This reduces the overall test suite time by about 10% on my laptop.
(Andrew Bennetts)
* Update `TestCase.knownFailure` to the testtools way of handling expected
failures to resolve Python 2.7 incompatibility. (Martin [gz], #607400)
