Bazaar Release Notes

--------------------

.. contents::

IN DEVELOPMENT

--------------

This release adds a translation of some of the user documentation into Spanish.

(Contributions of other translations would be very welcome.)

  NOTES WHEN UPGRADING:

  CHANGES:

    * Deprecation warnings will not be suppressed when running ``bzr selftest``

      so that developers can see if their code is using deprecated functions.

      (John Arbash Meinel)

  FEATURES:

    * Adding ``-Derror`` will now display a traceback when a plugin fails to

      load. (James Westby)

    * There is a new version of the network protocol used for bzr://, bzr+ssh://

      and bzr+http:// connections.  This will allow more efficient requests and

      responses, and more graceful fallback when a server is too old to

      recognise a request from a more recent client.  Bazaar 1.6 will

      interoperate with 0.16 and later versions, but servers should be upgraded

      when possible.  Bazaar 1.6 no longer interoperates with 0.15 and earlier via

      these protocols.  Use alternatives like SFTP or upgrade those servers.

      (Andrew Bennetts, #83935)

  IMPROVEMENTS:

    * ``bzr branch/push/pull -r XXX`` now have a helper function for finding

      the revno of the new revision (``Graph.find_distance_to_null``). This

      should make something like ``bzr branch -r -100`` in a shared, no-trees

      repository much snappier. (John Arbash Meinel)

    * ``bzr log --short -r X..Y`` no longer needs to access the full revision

      history. This makes it noticeably faster when logging the last few

      revisions. (John Arbash Meinel)

    * ``bzr ls`` now accepts ``-V`` as an alias for ``--versioned``. 

      (Jerad Cramp, #165086)

    * ``bzr missing`` uses the new ``Graph.find_unique_ancestors`` and

      ``Graph.find_differences`` to determine missing revisions without having

      to search the whole ancestry. (John Arbash Meinel, #174625)

    * ``bzr uncommit`` now uses partial history access, rather than always

      extracting the full revision history for a branch. This makes it

      resolve the appropriate revisions much faster (in testing it drops

      uncommit from 1.5s => 0.4s). It also means ``bzr log --short`` is one

      step closer to not using full revision history.

      (John Arbash Meinel, #172649)

  BUGFIXES:

    * ``bzr merge --lca`` should handle when two revisions have no common

      ancestor other than NULL_REVISION. (John Arbash Meinel, #235715)

    * ``bzr push`` with both ``--overwrite`` and ``-r NNN`` options no longer

      fails.  (Andrew Bennetts, #234229)

    * Correctly track the base URL of a smart medium when using bzr+http://

      URLs, which was causing spurious "No repository present" errors with

      branches in shared repositories accessed over bzr+http.

      (Andrew Bennetts, #230550)

    * Define ``_remote_is_at_least_1_2`` on ``SmartClientMedium`` so that all

      implementations have the attribute.  Fixes 'PyCurlTransport' object has no

      attribute '_remote_is_at_least_1_2' attribute errors.

      (Andrew Bennetts, #220806)

    * Failure to delete an obsolete pack file should just give a warning

      message, not a fatal error.  It may for example fail if the file is still

      in use by another process.

      (Martin Pool)

    * Fix MemoryError during large fetches over HTTP by limiting the amount of

      data we try to read per ``recv`` call.  The problem was observed with

      Windows and a proxy, but might affect other environments as well.

      (Eric Holmberg, #215426)

    * Handle old merge directives correctly in Merger.from_mergeable.  Stricter

      get_parent_map requirements exposed a latent bug here.  (Aaron Bentley)

    * Issue a warning and ignore passwords declared in authentication.conf when

      used for an ssh scheme (sftp or bzr+ssh).

      (Vincent Ladeuil, #203186)

    * Make both http implementations raise appropriate exceptions on 403

      Forbidden when POSTing smart requests.

      (Vincent Ladeuil, #230223)

    * Properly *title* header names in http requests instead of capitalizing

      them.

      (Vincent Ladeuil, #229076)

    * Treat an encoding of '' as ascii; this can happen when bzr is run

      under vim on Mac OS X.

      (Neil Martinsen-Burrell)

  DOCUMENTATION:

    * Added directory structure and started translation of docs in spanish.

      (Martin Albisetti, Lucio Albenga)

    * Incorporate feedback from Jelmer Vernooij and Neil Martinsen-Burrell

      on the plugin and integration chapters of the User Guide.

      (Ian Clatworthy)

    * More Bazaar developer documentation about packaging and release process,

      and about use of Python reprs.

      (Martin Pool, Martin Albisetti)

    * Updated Tortise strategy document. (Mark Hammond)

  TESTING:

    * New helper function for splitting test suites

      ``split_suite_by_condition``. (Robert Collins)

  INTERNALS:

  API CHANGES:

    * ``Branch.abspath`` is deprecated; use the Tree or Transport 

      instead.  (Martin Pool)

    * ``Branch.update_revisions`` now takes an optional ``Graph``

      object. This can be used by ``update_revisions`` when it is

      checking ancestry, and allows callers to prefer request to go to a

      local branch.  (John Arbash Meinel)

    * Branch, Repository, Tree and BzrDir should expose a Transport as an

      attribute if they have one, rather than having it indirectly accessible

      as ``.control_files._transport``.  This doesn't add a requirement

      to support a Transport in cases where it was not needed before;

      it just simplifies the way it is reached.  (Martin Pool)

    * ``bzr missing --mine-only`` will return status code 0 if you have no

      new revisions, but the remote does. Similarly for ``--theirs-only``.

      The new code only checks one side, so it doesn't know if the other

      side has changes. This seems more accurate with the request anyway.

      It also changes the output to print '[This|Other] branch is up to

      date.' rather than displaying nothing.  (John Arbash Meinel)

    * ``LockableFiles.put_utf8``, ``put_bytes`` and ``controlfilename``

      are now deprecated in favor of using Transport operations.

      (Martin Pool)

    * Many methods on ``VersionedFile``, ``Repository`` and in

      ``bzrlib.revision``  deprecated before bzrlib 1.5 have been removed.

      (Robert Collins)

    * ``RevisionSpec.wants_revision_history`` can be set to False for a given

      ``RevisionSpec``. This will disable the existing behavior of passing in

      the full revision history to ``self._match_on``. Useful for specs that

      don't actually need access to the full history. (John Arbash Meinel)

    * The constructors of ``SmartClientMedium`` and its subclasses now require a

      ``base`` parameter.  ``SmartClientMedium`` implementations now also need

      to provide a ``remote_path_from_transport`` method.  (Andrew Bennetts)

    * The default permissions for creating new files and directories 

      should now be obtained from ``BzrDir._get_file_mode()`` and 

      ``_get_dir_mode()``, rather than from LockableFiles.  The ``_set_file_mode``

      and ``_set_dir_mode`` variables on LockableFiles which were advertised

      as a way for plugins to control this are no longer consulted.

      (Martin Pool)

    * ``VersionedFile.join`` is deprecated. This method required local

      instances of both versioned file objects and was thus hostile to being

      used for streaming from a smart server. The new get_record_stream and

      insert_record_stream are meant to efficiently replace this method.

      (Robert Collins)

    * ``WorkingTreeFormat2.stub_initialize_remote`` is now private.

      (Martin Pool) 

bzr 1.5 2008-05-16

------------------

This release of Bazaar includes several updates to the documentation, and fixes

to prepare for making rich root support the default format. Many bugs have been

squashed, including fixes to log, bzr+ssh inter-operation with older servers.

  CHANGES:

    * Suppress deprecation warnings when bzrlib is a 'final' release. This way

      users of packaged software won't be bothered with DeprecationWarnings,

      but developers and testers will still see them. (John Arbash Meinel)

  DOCUMENTATION:

    * Incorporate feedback from Jelmer Vernooij and Neil Martinsen-Burrell

      on the plugin and integration chapters of the User Guide.

      (Ian Clatworthy)

bzr 1.5rc1 2008-05-09

---------------------

  NOTES WHEN UPGRADING:

  CHANGES:

    * Broader support of GNU Emacs mail clients. Set

      ``mail_client=emacsclient`` in your bazaar.conf and ``send`` will pop the

      bundle in a mail buffer according to the value of ``mail-user-agent``

      variable. (Xavier Maillard)

  FEATURES:

  IMPROVEMENTS:

    * Diff now handles revision specs like "branch:" and "submit:" more

      efficiently.  (Aaron Bentley)

    * More friendly error given when attempt to start the smart server

      on an address already in use. (Andrea Corbellini, #200575)

    * Pull completes much faster when there is nothing to pull.

      (Aaron Bentley)

  BUGFIXES:

    * Authentication.conf can define sections without password.

      (Vincent Ladeuil, #199440)

    * Avoid muttering every time a child update does not cause a progress bar

      update. (John Arbash Meinel, #213771)

    * ``Branch.reconcile()`` is now implemented. This allows ``bzr reconcile``

      to fix when a Branch has a non-canonical mainline history. ``bzr check``

      also detects this condition. (John Arbash Meinel, #177855)

    * ``bzr log -r ..X bzr://`` was failing, because it was getting a request

      for ``revision_id=None`` which was not a string.

      (John Arbash Meinel, #211661)

    * ``bzr commit`` now works with Microsoft's FTP service.

      (Andreas Deininger)

    * Catch definitions outside sections in authentication.conf.

      (Vincent Ladeuil, #217650)

    * Conversion from non-rich-root to rich-root(-pack) updates inventory

      sha1s, even when bundles are used.  (Aaron Bentley, #181391)

    * Conversion from non-rich-root to rich-root(-pack) works correctly even

      though search keys are not topologically sorted.  (Aaron Bentley)

    * Conversion from non-rich-root to rich-root(-pack) works even when a

      parent revision has a different root id.  (Aaron Bentley, #177874)

    * Disable strace testing until strace is fixed (see bug #103133) and emit a

      warning when selftest ends to remind us of leaking tests.

      (Vincent Ladeuil, #226769)

    * Fetching all revisions from a repository does not cause pack collisions.

      (Robert Collins, Aaron Bentley, #212908)

    * Fix error about "attempt to add line-delta in non-delta knit".

      (Andrew Bennetts, #217701)

    * Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break

      if the remote server was < version 1.2. This was due to a bug in the

      RemoteRepository.get_parent_map() fallback code.

      (John Arbash Meinel, #214894)

    * Remove leftover code in ``bzr_branch`` that inappropriately creates 

      a ``branch-name`` file in the branch control directory.

      (Martin Pool)

    * Set SO_REUSEADDR on server sockets of ``bzr serve`` to avoid problems

      rebinding the socket when starting the server a second time.

      (John Arbash Meinel, Martin Pool, #164288)

    * Severe performance degradation in fetching from knit repositories to

      knits and packs due to parsing the entire revisions.kndx on every graph

      walk iteration fixed by using the Repository.get_graph API.  There was

      another regression in knit => knit fetching which re-read the index for

      every revision each side had in common.

      (Robert Collins, John Arbash Meinel)

    * When logging the changes to a particular file, there was a bug if there

      were ghosts in the revision ancestry. (John Arbash Meinel, #209948)

    * xs4all's ftp server returns a temporary error when trying to list an

      empty directory, rather than returning an empty list. Adding a

      workaround so that we don't get spurious failures.

      (John Arbash Meinel, #215522)

  DOCUMENTATION:

    * Expanded the User Guide to include new chapters on popular plugins and

      integrating Bazaar into your environment. The *Best practices* chapter

      was renamed to *Miscellaneous topics* as suggested by community

      feedback as well. (Ian Clatworthy)

    * Document outlining strategies for TortoiseBzr. (Mark Hammond)

    * Improved the documentation on hooks. (Ian Clatworthy)

    * Update authentication docs regarding ssh agents.

      (Vincent Ladeuil, #183705)

  TESTING:

    * Add ``thread_name_suffix`` parameter to SmartTCPServer_for_testing, to

      make it easy to identify which test spawned a thread with an unhandled

      exception. (Andrew Bennetts)

    * New ``--debugflag``/``-E`` option to ``bzr selftest`` for setting

      options for debugging tests, these are complementary to the the -D

      options.  The ``-Dselftest_debug`` global option has been replaced by the

      ``-E=allow_debug`` option for selftest. (Andrew Bennetts)

    * Parameterised test ids are preserved correctly to aid diagnosis of test

      failures. (Robert Collins, Andrew Bennetts)

    * selftest now accepts --starting-with <id> to load only the tests whose id

      starts with the one specified. This greatly speeds up running the test

      suite on a limited set of tests and can be used to run the tests for a

      single module, a single class or even a single test.  (Vincent Ladeuil)

    * The test suite modules have been modified to define load_tests() instead

      of test_suite(). That speeds up selective loading (via --load-list)

      significantly and provides many examples on how to migrate (grep for

      load_tests).  (Vincent Ladeuil)

  INTERNALS:

    * ``Hooks.install_hook`` is now deprecated in favour of

      ``Hooks.install_named_hook`` which adds a required ``name`` parameter, to

      avoid having to call ``Hooks.name_hook``. (Daniel Watkins)

    * Implement xml8 serializer.  (Aaron Bentley)

    * New form ``@deprecated_method(deprecated_in(1, 5, 0))`` for making 

      deprecation wrappers.  (Martin Pool)

    * ``Repository.revision_parents`` is now deprecated in favour of 

      ``Repository.get_parent_map([revid])[revid]``. (Jelmer Vernooij)

    * The Python ``assert`` statement is no longer used in Bazaar source, and 

      a test checks this.  (Martin Pool)

  API BREAKS:

    * ``bzrlib.status.show_pending_merges`` requires the repository to be

      locked by the caller. Callers should have been doing it anyway, but it

      will now raise an exception if they do not. (John Arbash Meinel)

    * Repository.get_data_stream, Repository.get_data_stream_for_search(),

      Repository.get_deltas_for_revsions(), Repository.revision_trees(),

      Repository.item_keys_introduced_by() no longer take read locks.

      (Aaron Bentley)

    * ``LockableFiles.get_utf8`` and ``.get`` are deprecated, as a start

      towards removing LockableFiles and ``.control_files`` entirely.

      (Martin Pool)

    * Methods deprecated prior to 1.1 have been removed.

      (Martin Pool)

bzr 1.4 2008-04-28

------------------

This release of Bazaar includes handy improvements to the speed of log and

status, new options for several commands, improved documentation, and better

hooks, including initial code for server-side hooks.  A number of bugs have

been fixed, particularly in interoperability between different formats or

different releases of Bazaar over there network.  There's been substantial

internal work in both the repository and network code to enable new features

and faster performance.

  BUG FIXES:

    * Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break

      if the remote server was < version 1.2.  This was due to a bug in the

      RemoteRepository.get_parent_map() fallback code.

      (John Arbash Meinel, Andrew Bennetts, #214894)

bzr 1.4rc2 2008-04-21

---------------------
