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.

* 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    only display if the branch is out-of-date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)

* 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.

* 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)

* 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 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)

* 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)

* 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)

Internals

*********

.. Major internal changes, unlikely to be visible to users or plugin 

   developers, but interesting for bzr developers.

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)

* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423)

* `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.
