Release notes

This is the first beta of the 2.5 series, leading up to a 2.5.0 release in February 2012. Beta releases are suitable for everyday use but may cause some incompatibilities with plugins. Some plugins may need small updates to work with 2.5b1.

External Compatibility Breaks


New Features

* 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

disable all checks

only display if the branch is out-of-date

also display single-line up-to-date and missing,

(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 'error' will respectively emit a warning and
ignore the value or errors out. (Vincent Ladeuil)

* bzr add now skips large files in recursive mode. The default "large"
size is 20MB, and is configurable via the add.maximum_file_size
option. A value of 0 disables skipping. Named items passed to add are
never skipped. (Shannon Weyrick, #54624)

* ``bzr help configuration/option`` display the help for ``option`` for
all registered configuration options. (Vincent Ladeuil, #747050)

* ``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. (Jacek Sieka)

* ``config.Option`` can now declare ``default_from_env``, a list of
environment variables to get a default value from. (Vincent Ladeuil)

* ``config.NameMatcher`` can be used to implement config stores and stacks
that need to provide specific option values for arbitrary unique IDs (svn
repository UUIDs, etc). (Vincent Ladeuil, #843638)

* New builtin ``bzr branches`` command, which lists all colocated branches
in a directory. (Jelmer Vernooij, #826820)

* Relative local paths can now be specified in URL syntax by using the
"file:" prefix. (Jelmer Vernooij)

* Report commits signed with expired keys in ``verify-signatures``.
(Jonathan Riddell, #804254)

* Translations are now enabled for command help, errors and globally
for any message using gettext given on output. (Jonathan Riddell,
INADA Naoki, #83941)


* ``bzr add`` will now warn about nested subtrees that are skipped.
(Jelmer Vernooij, #187342)

* ``bzr commit -m ''`` can now be used to force an empty commit message.
Entering an empty commit message in the message editor still triggers
an error. (Jelmer Vernooij)

* ``bzr pull`` will now mention how many tags it has updated.
(Jelmer Vernooij, #164450)

* ``bzr tag`` no longer errors if a tag already exists but refers to the
same revision, and will mention when a tag has been updated
rather than created. (Jelmer Vernooij, #381203)

* ``bzr uncommit`` will now remove tags that refer to removed revisions.
The ``--keep-tags`` option can be used to prevent this behaviour.
(Jelmer Vernooij, #605814)

* Do not run i18n initialisation twice. (Jonathan Riddell)

* Install translation .mo files. (Jonathan Riddell)

* Locations printed by ``bzr upgrade`` are now formatted before display.
(Jelmer Vernooij)

* ``Repository.get_parent_map`` now estimates the size of the returned
content more accurately. This means that we get closer to the desired
64kB/request. For repositories converted from svn, this can be an
improvement of approx 5:1 in round trips to discover the whole history.
(John Arbash Meinel)

* Support a ``bugtracker`` option which is used by ``bzr commit --fixes``
if no bug tracker was specified on the command line.
(Jelmer Vernooij, #334860)

* Use gettext.NullTranslations in i18n to allow use of i18n even when
translations are not turned on. (Jonathan Riddell)

Bug Fixes

* ``bzr commit`` now correctly reports missing files as "removed", not
"modified". (Jelmer Vernooij, #553955)

* ``bzr reconfigure`` will now allow multiple non-conflicting requests
in a single invocation, e.g. ``--branch`` and ``--use-shared``.
(Martin von Gagern, #842993)

* 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)

* Branching from a stacked branch no longer does a ``get_parent_map``
request for each revisions that is in the stacked-on repository while
determining what revisions need to be fetched. This mostly impacts
branching initialy into an empty shared repository when the source is
not the development focus. (John Arbash Meinel, #388269)

* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode
errors. (Vincent Ladeuil, #822571)

* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be
raised whenever a transport at the drive root was opened on windows.
(Martin [gz], #841322)

* Fixed loading of external merge tools from config to properly decode
command-lines which contain embedded quotes. (Gordon Tyler, #828803)

* Rather than an error being raised, a warning is now printed when the
current user does not have permission to read a configuration file.
(Jelmer Vernooij, #837324)

* The pull command will now always use separate connections for the
case where the destination is a heavyweight checkout of some remote
branch on the same host as the source branch.
(Martin von Gagern, #483661)

* 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)


* Release instructions refreshed. (Vincent Ladeuil)

API Changes

* ``BranchFormat.initialize`` now takes a ``append_revisions_only``
argument. (Jelmer Vernooij)

* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument
which indicates if the format should be for a lightweight or a
heavyweight checkout. (Jelmer Vernooij)

* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument.
(Jelmer Vernooij)

* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs.
(Jelmer Vernooij)

* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a
value in SI format (i.e. "20MB", "1GB") into its integer equivalent.
(Shannon Weyrick)

* New method ``InterTree.file_content_matches`` which checks that
two files in different trees have the same contents.
(Jelmer Vernooij)

* New method ``Tree.get_file_verifier`` which allows tree implementations
to return non-sha1 checksums to verify files.
(Jelmer Vernooij, #720831)

* 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 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.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)

* ``Tags`` containers can now declare whether they support versioned
tags and whether tags can refer to ghost tags.
(Jelmer Vernooij)

* ``Tags.merge_to`` now returns a dictionary with the updated tags
and a set of conflicts, rather than just conflicts. (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)


* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client
to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request
is attempted. (Jelmer Vernooij)

* New method ``ControlDir._get_selected_branch`` which returns the
colocated branch selected using path segment parameters.
(Jelmer Vernooij, #380871)


* Blackbox tests (including test scripts) can be debugged interactively (see
bzrlib.debug.BzrPdb for details). (Vincent Ladeuil)

* `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)

* Output time stamps while running ``make check`` to get better timings from
pqm. (Vincent Ladeuil, #837926)

* `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)
