Bazaar Release Notes

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

.. contents::

IN DEVELOPMENT

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

  CHANGES:

    * Fetching via bzr+ssh will no longer fill ghosts by default (this is

      consistent with pack-0.92 fetching over SFTP). (Robert Collins)

    * Formatting of ``bzr plugins`` output is changed to be more human-

      friendly. Full path of plugins locations will be shown only with

      ``--verbose`` command-line option. (Alexander Belchenko)

    * ``merge`` now prefers to use the submit branch, but will fall back to

      parent branch.  For many users, this has no effect.  But some users who

      pull and merge on the same branch will notice a change.  This change

      makes it easier to work on a branch on two different machines, pulling

      between the machines, while merging from the upstream.

      ``merge --remember`` can now be used to set the submit_branch.

      (Aaron Bentley)

  FEATURES:

    * ``merge --preview`` produces a diff of the changes merge would make,

      but does not actually perform the merge.  (Aaron Bentley)

    * New smart method, ``Repository.stream_revisions_chunked``, for fetching

      revision data that streams revision data via a chunked encoding.  This

      avoids buffering large amounts of revision data on the server and on the

      client, and sends less data to the server to request the revisions.

      (Andrew Bennetts, Robert Collins, #178353)

    * The launchpad plugin now handles lp urls of the form

      ``lp://staging/``, ``lp://demo/``, ``lp://dev/`` to use the appropriate

      launchpad instance to do the resolution of the branch identities.

      This is primarily of use to Launchpad developers, but can also

      be used by other users who want to try out Launchpad as

      a branch location without messing up their public Launchpad

      account.  Branches that are pushed to the staging environment

      have an expected lifetime of one day. (Tim Penhey)

  IMPROVEMENTS:

    * Creating a new branch no longer tries to read the entire revision-history

      unnecessarily over smart server operations. (Robert Collins)

    * Fetching between different repository formats with compatible models now

      takes advantage of the smart method to stream revisions.  (Andrew Bennetts)

    * The ``--coverage`` option is now global, rather specific to ``bzr

      selftest``.  (Andrew Bennetts)

    * The ``register-branch`` command will now use the public url of the branch

      containing the current directory, if one has been set and no explicit

      branch is provided.  (Robert Collins)

    * Tweak the ``reannotate`` code path to optimize the 2-parent case.

      Speeds up ``bzr annotate`` with a pack repository by approx 3:2.

      (John Arbash Meinel)

  BUGFIXES:

    * Calculate remote path relative to the shared medium in _SmartClient.  This

      is related to the problem in bug #124089.  (Andrew Bennetts)

    * Cleanly handle connection errors in smart protocol version two, the same

      way as they are handled by version one.  (Andrew Bennetts)

    * List possible values for BZR_SSH environment variable in env-variables

      help topic. (Alexander Belchenko, #181842)

    * pull --quiet is now more quiet, in particular a message is no longer

      printed when the remembered pull location is used. (James Westby,

      #185907)

    * ``reconfigure`` can safely be interrupted while fetching.

      (Aaron Bentley, #179316)

    * ``reconfigure`` preserves tags when converting to and from lightweight

      checkouts.  (Aaron Bentley, #182040)

    * Stop polluting /tmp when running selftest.

      (Vincent Ladeuil, #123623)

    * Switch from NFKC => NFC for normalization checks. NFC allows a few

      more characters which should be considered valid.

      (John Arbash Meinel, #185458)

    * The launchpad plugin now uses the ``edge`` xmlrpc server to avoid

      interacting badly with a bug on the launchpad side. (Robert Collins)

    * Unknown hostnames when connecting to a ``bzr://`` URL no longer cause

      tracebacks.  (Andrew Bennetts, #182849)

  API BREAKS:

    * Classes implementing Merge types like Merge3Merger must now accept (and

      honour) a do_merge flag in their constructor.  (Aaron Bentley)

    * ``Repository.add_inventory`` and ``add_revision`` now require the caller

      to previously take a write lock (and start a write group.)

      (Martin Pool)

  TESTING:

   * selftest now accepts --load-list <file> to load a test id list. This

     speeds up running the test suite on a limited set of tests.

     (Vincent Ladeuil)

  INTERNALS:

    * Add a new method ``get_result`` to graph search objects. The resulting

      ``SearchResult`` can be used to recreate the search later, which will

      be useful in reducing network traffic. (Robert Collins)

    * Use convenience function to check whether two repository handles 

      are referring to the same repository in ``Repository.get_graph``. 

      (Jelmer Vernooij, #187162)

    * Fetching now passes the find_ghosts flag through to the 

      ``InterRepository.missing_revision_ids`` call consistently for all

      repository types. This will enable faster missing revision discovery with

      bzr+ssh. (Robert Collins)

    * Fix error handling in Repository.insert_data_stream. (Lukas Lalinsky)

    * ``InterRepository.missing_revision_ids`` is now deprecated in favour of

      ``InterRepository.search_missing_revision_ids`` which returns a 

      ``bzrlib.graph.SearchResult`` suitable for making requests from the smart

      server. (Robert Collins)

    * New error ``NoPublicBranch`` for commands that need a public branch to

      operate. (Robert Collins)

    * New method ``iter_inventories`` on Repository for access to many

      inventories. This is primarily used by the ``revision_trees`` method, as

      direct access to inventories is discouraged. (Robert Collins)

    * New method ``next_with_ghosts`` on the Graph breadth-first-search objects

      which will split out ghosts and present parents into two separate sets,

      useful for code which needs to be aware of ghosts (e.g. fetching data

      cares about ghosts during revision selection). (Robert Collins)

    * Record a timestamp against each mutter to the trace file, relative to the

      first import of bzrlib.  (Andrew Bennetts)

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

      ``Repository.get_data_stream_for_search`` which allows less network

      traffic when requesting data streams over a smart server. (Robert Collins)

    * ``RemoteBzrDir._get_tree_branch`` no longer triggers ``_ensure_real``,

      removing one round trip on many network operations. (Robert Collins)

    * Repository has a new method ``has_revisions`` which signals the presence

      of many revisions by returning a set of the revisions listed which are

      present. This can be done by index queries without reading data for parent

      revision names etc. (Robert Collins)

    * RemoteTransport's ``recommended_page_size`` method now returns 64k, like

      SFTPTransport and HttpTransportBase.  (Andrew Bennetts)

bzr 1.1 2008-01-15

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

(no changes from 1.1rc1)

bzr 1.1rc1 2008-01-05

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

  CHANGES:

   * Dotted revision numbers have been revised. Instead of growing longer with

     nested branches the branch number just increases. (eg instead of 1.1.1.1.1

     we now report 1.2.1.) This helps scale long lived branches which have many

     feature branches merged between them. (John Arbash Meinel)

   * The syntax ``bzr diff branch1 branch2`` is no longer supported.

     Use ``bzr diff branch1 --new branch2`` instead. This change has

     been made to remove the ambiguity where ``branch2`` is in fact a

     specific file to diff within ``branch1``.

  FEATURES:

   * New option to use custom template-based formats in  ``bzr version-info``.

     (Lukáš Lalinský)

   * diff '--using' allows an external diff tool to be used for files.

     (Aaron Bentley)

   * New "lca" merge-type for fast everyday merging that also supports

     criss-cross merges.  (Aaron Bentley)

  IMPROVEMENTS:

   * ``annotate`` now doesn't require a working tree. (Lukáš Lalinský,

     #90049)

   * ``branch`` and ``checkout`` can now use files from a working tree to

     to speed up the process.  For checkout, this requires the new

     --files-from flag.  (Aaron Bentley)

   * ``bzr diff`` now sorts files in alphabetical order.  (Aaron Bentley)

   * ``bzr diff`` now works on branches without working trees. Tree-less

     branches can also be compared to each other and to working trees using

     the new diff options ``--old`` and ``--new``. Diffing between branches,

     with or without trees, now supports specific file filtering as well.

     (Ian Clatworthy, #6700)

   * ``bzr pack`` now orders revision texts in topological order, with newest

     at the start of the file, promoting linear reads for ``bzr log`` and the

     like. This partially fixes #154129. (Robert Collins)

   * Merge directives now fetch prerequisites from the target branch if

     needed.  (Aaron Bentley)

   * pycurl now handles digest authentication.

     (Vincent Ladeuil)

   * ``reconfigure`` can now convert from repositories.  (Aaron Bentley)

   * ``-l`` is now a short form for ``--limit`` in ``log``.  (Matt Nordhoff)

   * ``merge`` now warns when merge directives cause cherrypicks.

     (Aaron Bentley)

   * ``split`` now supported, to enable splitting large trees into smaller

     pieces.  (Aaron Bentley)

  BUGFIXES:

   * Avoid AttributeError when unlocking a pack repository when an error occurs.

     (Martin Pool, #180208)

   * Better handle short reads when processing multiple range requests.

     (Vincent Ladeuil, #179368)

   * build_tree acceleration uses the correct path when a file has been moved.

     (Aaron Bentley)

   * ``commit`` now succeeds when a checkout and its master branch share a

     repository.  (Aaron Bentley, #177592)

   * Fixed error reporting of unsupported timezone format in

     ``log --timezone``. (Lukáš Lalinský, #178722)

   * Fixed Unicode encoding error in ``ignored`` when the output is

     redirected to a pipe. (Lukáš Lalinský)

   * Fix traceback when sending large response bodies over the smart protocol

     on Windows. (Andrew Bennetts, #115781)

   * Fix ``urlutils.relative_url`` for the case of two ``file:///`` URLs

     pointed to different logical drives on Windows.

     (Alexander Belchenko, #90847)

   * HTTP test servers are now compatible with the http protocol version 1.1.

     (Vincent Ladeuil, #175524)

   * _KnitParentsProvider.get_parent_map now handles requests for ghosts

     correctly, instead of erroring or attributing incorrect parents to ghosts.

     (Aaron Bentley)

   * ``merge --weave --uncommitted`` now works.  (Aaron Bentley)

   * pycurl authentication handling was broken and incomplete. Fix handling of

     user:pass embedded in the urls.

     (Vincent Ladeuil, #177643)

   * Files inside non-directories are now handled like other conflict types.

     (Aaron Bentley, #177390)

   * ``reconfigure`` is able to convert trees into lightweight checkouts.

     (Aaron Bentley)

   * Reduce lockdir timeout to 0 when running ``bzr serve``.  (Andrew Bennetts,

     #148087)

   * Test that the old ``version_info_format`` functions still work, even

     though they are deprecated. (John Arbash Meinel, ShenMaq, #177872)

   * Transform failures no longer cause ImmortalLimbo errors (Aaron Bentley,

     #137681)

   * ``uncommit`` works even when the commit messages of revisions to be

     removed use characters not supported in the terminal encoding.

     (Aaron Bentley)

   * When dumb http servers return whole files instead of the requested ranges,

     read the remaining bytes by chunks to avoid overflowing network buffers.

     (Vincent Ladeuil, #175886)

  DOCUMENTATION:

   * Minor tweaks made to the bug tracker integration documentation.

     (Ian Clatworthy)

   * Reference material has now be moved out of the User Guide and added

     to the User Reference. The User Reference has gained 4 sections as

     a result: Authenication Settings, Configuration Settings, Conflicts

     and Hooks. All help topics are now dumped into text format in the

     doc/en/user-reference directory for those who like browsing that

     information in their editor. (Ian Clatworthy)

   * *Using Bazaar with Launchpad* tutorial added. (Ian Clatworthy)

  INTERNALS:

    * find_* methods available for BzrDirs, Branches and WorkingTrees.

      (Aaron Bentley)

    * Help topics can now be loaded from files. 

      (Ian Clatworthy, Alexander Belchenko)

    * get_parent_map now always provides tuples as its output.  (Aaron Bentley)

    * Parent Providers should now implement ``get_parent_map`` returning a

      dictionary instead of ``get_parents`` returning a list.

      ``Graph.get_parents`` is now deprecated. (John Arbash Meinel,

      Robert Collins)

    * Patience Diff now supports arbitrary python objects, as long as they

      support ``hash()``. (John Arbash Meinel)

    * Reduce selftest overhead to establish test names by memoization.

      (Vincent Ladeuil)

  API BREAKS:

  TESTING:

   * Modules can now customise their tests by defining a ``load_tests``

     attribute. ``pydoc bzrlib.tests.TestUtil.TestLoader.loadTestsFromModule``

     for the documentation on this attribute. (Robert Collins)

   * New helper function ``bzrlib.tests.condition_id_re`` which helps

     filter tests based on a regular expression search on the tests id.

     (Robert Collins)

   * New helper function ``bzrlib.tests.condition_isinstance`` which helps

     filter tests based on class. (Robert Collins)

   * New helper function ``bzrlib.tests.exclude_suite_by_condition`` which

     generalises the ``exclude_suite_by_re`` function. (Robert Collins)

   * New helper function ``bzrlib.tests.filter_suite_by_condition`` which

     generalises the ``filter_suite_by_re`` function. (Robert Collins)

   * New helper method ``bzrlib.tests.exclude_tests_by_re`` which gives a new

     TestSuite that does not contain tests from the input that matched a

     regular expression. (Robert Collins)

   * New helper method ``bzrlib.tests.randomize_suite`` which returns a

     randomized copy of the input suite. (Robert Collins)

   * New helper method ``bzrlib.tests.split_suite_by_re`` which splits a test

     suite into two according to a regular expression. (Robert Collins)

   * Parametrize all http tests for the transport implementations, the http

     protocol versions (1.0 and 1.1) and the authentication schemes.

     (Vincent Ladeuil) 

   * The ``exclude_pattern`` and ``random_order`` parameters to the function

     ``bzrlib.tests.filter_suite_by_re`` have been deprecated. (Robert Collins)

   * The method ``bzrlib.tests.sort_suite_by_re`` has been deprecated. It is 

     replaced by the new helper methods added in this release. (Robert Collins)

bzr 1.0 2007-12-14

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

  DOCUMENTATION:

   * More improvements and fixes to the User Guide.  (Ian Clatworthy)

   * Add information on cherrypicking/rebasing to the User Guide.

     (Ian Clatworthy)

   * Improve bug tracker integration documentation. (Ian Clatworthy)

   * Minor edits to ``Bazaar in five minutes`` from David Roberts and

     to the rebasing section of the User Guide from Aaron Bentley.

     (Ian Clatworthy)

bzr 1.0rc3 2007-12-11

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

  CHANGES:

   * If a traceback occurs, users are now asked to report the bug 

     through Launchpad (https://bugs.launchpad.net/bzr/), rather than 

     by mail to the mailing list.

     (Martin Pool)

  BUGFIXES:

   * Fix Makefile rules for doc generation. (Ian Clatworthy, #175207)

   * Give more feedback during long http downloads by making readv deliver data

     as it arrives for urllib, and issue more requests for pycurl. High latency

     networks are better handled by urllib, the pycurl implementation give more

     feedback but also incur more latency.

     (Vincent Ladeuil, #173010)

   * Implement _make_parents_provider on RemoteRepository, allowing generating

     bundles against branches on a smart server.  (Andrew Bennetts, #147836)

  DOCUMENTATION:

   * Improved user guide.  (Ian Clatworthy)

   * The single-page quick reference guide is now available as a PDF.
