IN DEVELOPMENT

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

  NOTES WHEN UPGRADING:

  CHANGES:

   * bzr main script cannot be imported (Benjamin Peterson)

   * When a plugin cannot be loaded as the file path is not a valid

     python module name bzr will now strip a ``bzr_`` prefix from the

     front of the suggested name, as many plugins (e.g. bzr-svn)

     want to be installed without this prefix. It is a common mistake

     to have a folder named "bzr-svn" for that plugin, especially

     as this is what bzr branch lp:bzr-svn will give you. (James Westby,

     Andrew Cowie)

  FEATURES:

    * Added mail-mode GNU Emacs mail package as a mail_client.

      (Xavier Maillard, Bojan Nikolic)

  IMPROVEMENTS:

    * Diff is now more specific about execute-bit changes it describes

      (Chad Miller)

    * Fetching data over HTTP is a bit faster when urllib is used.  This is done

      by forcing it to recv 64k at a time when reading lines in HTTP headers,

      rather than just 1 byte at a time.  (Andrew Bennetts)

    * Log --short and --line are much faster when -r is not specified.

      (Aaron Bentley)

    * Merge is faster.  We no longer check a file's existence unnecessarily

      when merging the execute bit.  (Aaron Bentley)

    * ``bzr status`` on an explicit list of files no longer shows pending

      merges, making it much faster on large trees. (John Arbash Meinel)

    * The launchpad directory service now warns the user if they have not set

      their launchpad login and are trying to resolve a URL using it, just

      in case they want to do a write operation with it.  (James Westby)

    * The smart protocol client is slightly faster, because it now only queries

      the server for the protocol version once per connection.  Also, the HTTP

      transport will now automatically use a smart server if one is present.

      (Andrew Bennetts)

     * Various operations with revision specs and commands that calculate

       revnos and revision ids are faster.  (John A. Meinel, Aaron Bentley)

  BUGFIXES:

    * Add ``root_client_path`` parameter to SmartWSGIApp and

      SmartServerRequest.  This makes it possible to publish filesystem

      locations that don't exactly match URL paths. SmartServerRequest

      subclasses should use the new ``translate_client_path`` and

      ``transport_from_client_path`` methods when dealing with paths received

      from a client to take this into account.  (Andrew Bennetts, #124089)

    * ``bzr mv a b`` can be now used also to rename previously renamed

      directories, not only files. (Lukáš Lalinský, #107967)

    * ``bzr uncommit --local`` can now remove revisions from the local

      branch to be symmetric with ``bzr commit --local``.

      (John Arbash Meinel, #93412)

    * Don't ask for a password if there is no real terminal.

      (Alexander Belchenko, #69851)

    * Implement handling of basename parameter for DefaultMail.  (James Westby)

    * Launchpad locations (lp: URLs) can be pulled.  (Aaron Bentley, #181945)

    * vsftp's return ``550 RNFR command failed.`` supported.

      (Marcus Trautwig, #129786)

  DOCUMENTATION:

    * Improved documentation on send/merge relationship. (Peter Schuller)

    * Minor fixes to the User Guide. (Matthew Fuller)

    * Reduced the evangelism in the User Guide. (Ian Clatworthy)

  API BREAKS:

    * Attempting to pull data from a ghost aware repository (e.g. knits) into a

      non-ghost aware repository such as weaves will now fail if there are

      ghosts.  (Robert Collins)

    * Log formatters must now provide log_revision instead of show and

      show_merge_revno methods. The latter had been deprecated since the 0.17

      release. (James Westby)

    * ``Repository.get_revision_graph`` is deprecated, with no replacement

      method. The method was size(history) and not desirable. (Robert Collins)

    * ``revision.revision_graph`` is deprecated, with no replacement function.

      The function was size(history) and not desirable. (Robert Collins)

    * ``Transport.get_shared_medium`` is deprecated.  Use

      ``Transport.get_smart_medium`` instead.  (Andrew Bennetts)

    * ``VersionedFile.get_graph`` is deprecated, with no replacement method.

      The method was size(history) and not desirable. (Robert Collins)

    * ``VersionedFile.get_graph_with_ghosts`` is deprecated, with no

      replacement method.  The method was size(history) and not desirable.

      (Robert Collins)

    * ``VersionedFile.get_parents`` is deprecated, please use

      ``VersionedFile.get_parent_map``. (Robert Collins)

    * ``VersionedFile.has_ghost`` is now deprecated, as it is both expensive

      and unused outside of a single test. (Robert Collins)

  TESTING:

    * New -Dselftest_debug flag disables clearing of the debug flags during

      tests.  This is useful if you want to use e.g. -Dhpss to help debug a

      failing test.  Be aware that using this feature is likely to cause

      spurious test failures if used with the full suite. (Andrew Bennetts)

    * selftest --load-list now does some sanity checks regarding duplicate test

      IDs and tests present in the list but not found in the actual test suite.

      (Vincent Ladeuil)

    * The test suite takes much less memory to run, and is a bit faster.  This

      is done by clearing most attributes of TestCases after running them, if

      they succeeded.  (Andrew Bennetts)

  INTERNALS:

    * ``VersionedFile`` now has a new method ``get_parent_map`` which, like

      ``Graph.get_parent_map`` returns a dict of key:parents. (Robert Collins)

bzr 1.3 2008-03-20

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

Bazaar has become part of the GNU project <http://www.gnu.org>

Many operations that act on history, including ``log`` and ``annotate`` are now

substantially faster.  Several bugs have been fixed and several new options and

features have been added.

  TESTING:

    * Avoid spurious failure of ``TestVersion.test_version`` matching

      directory names.

      (#202778, Martin Pool)

bzr 1.3rc1 2008-03-16

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

  NOTES WHEN UPGRADING:

    * The backup directory created by ``upgrade`` is now called

      ``backup.bzr``, not ``.bzr.backup``. (Martin Albisetti)

  CHANGES:

    * A new repository format 'development' has been added. This format will

      represent the latest 'in-progress' format that the bzr developers are

      interested in getting early-adopter testing and feedback on.

      ``doc/developers/development-repo.txt`` has detailed information.

      (Robert Collins)

    * BZR_LOG environment variable controls location of .bzr.log trace file. 

      User can suppress writing messages to .bzr.log by using '/dev/null'

      filename (on Linux) or 'NUL' (on Windows). If BZR_LOG variable 

      is not defined but BZR_HOME is defined then default location

      for .bzr.log trace file is ``$BZR_HOME/.bzr.log``.

      (Alexander Belchenko)

    * ``launchpad`` builtin plugin now shipped as separate part in standalone

      bzr.exe, installed to ``C:\Program Files\Bazaar\plugins`` directory, 

      and standalone installer allows user to skip installation of this plugin.

      (Alexander Belchenko)

    * Restore auto-detection of plink.exe on Windows. (Dmitry Vasiliev)

    * Version number is now shown as "1.2" or "1.2pr2", without zeroed or

      missing final fields.  (Martin Pool)

  FEATURES:

    * ``branch`` and ``checkout`` can hard-link working tree files, which is

      faster and saves space.  (Aaron Bentley)

    * ``bzr send`` will now also look at the ``child_submit_to`` setting in

      the submit branch to determine the email address to send to. 

      (Jelmer Vernooij)

  IMPROVEMENTS:

    * BzrBranch._lefthand_history is faster on pack repos.  (Aaron Bentley)

    * Branch6.generate_revision_history is faster.  (Aaron Bentley)

    * Directory services can now be registered, allowing special URLs to be

      dereferenced into real URLs.  This is a generalization and cleanup of

      the lp: transport lookup.  (Aaron Bentley)

    * Merge directives that are automatically attached to emails have nicer

      filenames, based on branch-nick + revno. (Aaron Bentley)

    * ``push`` has a ``--revision`` option, to specify what revision to push up

      to.  (Daniel Watkins)

    * Significantly reducing execution time and network traffic for trivial 

      case of running ``bzr missing`` command for two identical branches.

      (Alexander Belchenko)

    * Speed up operations that look at the revision graph (such as 'bzr log').

      ``KnitPackRepositor.get_revision_graph`` uses ``Graph.iter_ancestry`` to

      extract the revision history. This allows filtering ghosts while

      stepping instead of needing to peek ahead. (John Arbash Meinel)

    * The ``hooks`` command lists installed hooks, to assist in debugging.

      (Daniel Watkins)

    * Updates to how ``annotate`` work. Should see a measurable improvement in

      performance and memory consumption for file with a lot of merges.

      Also, correctly handle when a line is introduced by both parents (it

      should be attributed to the first merge which notices this, and not

      to all subsequent merges.) (John Arbash Meinel)

  BUGFIXES:

    * Autopacking no longer holds the full set of inventory lines in

      memory while copying. For large repositories, this can amount to

      hundreds of MB of ram consumption.

      (Ian Clatworthy, John Arbash Meinel)

    * Cherrypicking when using ``--format=merge3`` now explictly excludes

      BASE lines. (John Arbash Meinel, #151731)

    * Disable plink's interactive prompt for password.

      (#107593, Dmitry Vasiliev)

    * Encode command line arguments from unicode to user_encoding before

      invoking external mail client in `bzr send` command.

      (#139318, Alexander Belchenko)

    * Fixed problem connecting to ``bzr+https://`` servers.

      (#198793, John Ferlito)

    * Improved error reporting in the Launchpad plugin. (Daniel Watkins,

      #196618)

    * Include quick-start-summary.svg file to python-based installer(s)

      for Windows. (#192924, Alexander Belchenko)

    * lca merge now respects specified files. (Aaron Bentley)

    * Make version-info --custom imply --all. (#195560, James Westby)

    * ``merge --preview`` now works for merges that add or modify

      symlinks (James Henstridge)

    * Redirecting the output from ``bzr merge`` (when the remembered

      location is used) now works. (John Arbash Meinel)

    * setup.py script explicitly checks for Python version.

      (Jari Aalto, Alexander Belchenko, #200569)

    * UnknownFormatErrors no longer refer to branches regardless of kind of

      unknown format. (Daniel Watkins, #173980)

    * Upgrade bundled ConfigObj to version 4.5.2, which properly quotes #

      signs, among other small improvements. (Matt Nordhoff, #86838)

    * Use correct indices when emitting LCA conflicts.  This fixes IndexError

      errors.  (Aaron Bentley, #196780)

  DOCUMENTATION:

    * Explained how to use ``version-info --custom`` in the User Guide.

      (Neil Martinsen-Burrell)

  API BREAKS:

    * Support for loading plugins from zip files and

      ``bzrlib.plugin.load_from_zip()`` function are deprecated.

      (Alexander Belchenko)

  TESTING:

    * The branch interface tests were invalid for branches using rich-root

      repositories because the empty string is not a valid file-id.

      (Robert Collins)

  INTERNALS:

    * ``Graph.iter_ancestry`` returns the ancestry of revision ids. Similar to

      ``Repository.get_revision_graph()`` except it includes ghosts and you can

      stop part-way through. (John Arbash Meinel)

    * New module ``tools/package_mf.py`` provide custom module finder for

      python packages (improves standard python library's modulefinder.py)

      used by ``setup.py`` script while building standalone bzr.exe.

      (Alexander Belchenko)

    * New remote method ``RemoteBzrDir.find_repositoryV2`` adding support for

      detecting external lookup support on remote repositories. This method is

      now attempted first when lookup up repositories, leading to an extra 

      round trip on older bzr smart servers. (Robert Collins)

    * Repository formats have a new supported-feature attribute

      ``supports_external_lookups`` used to indicate repositories which support

      falling back to other repositories when they have partial data.

      (Robert Collins)

    * ``Repository.get_revision_graph_with_ghosts`` and

      ``bzrlib.revision.(common_ancestor,MultipleRevisionSources,common_graph)``

      have been deprecated.  (John Arbash Meinel)

    * ``Tree.iter_changes`` is now a public API, replacing the work-in-progress

      ``Tree._iter_changes``. The api is now considered stable and ready for

      external users.  (Aaron Bentley)

    * The bzrdir format registry now accepts an ``alias`` keyword to

      register_metadir, used to indicate that a format name is an alias for

      some other format and thus should not be reported when describing the

      format. (Robert Collins)

bzr 1.2 2008-02-15

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

  BUG FIXES:

    * Fix failing test in Launchpad plugin. (Martin Pool)

bzr 1.2rc1 2008-02-13

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

  NOTES WHEN UPGRADING:

    * Fetching via the smart protocol may need to reconnect once during a fetch

      if the remote server is running Bazaar 1.1 or earlier, because the client

      attempts to use more efficient requests that confuse older servers.  You

      may be required to re-enter a password or passphrase when this happens.

      This won't happen if the server is upgraded to Bazaar 1.2.

      (Andrew Bennetts)

  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.get_parent_map`` for getting revision

      parent data. This returns additional parent information topologically

      adjacent to the requested data to reduce round trip latency impacts.

      (Robert Collins)

    * 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)

    * Clearer error when ``version-info --custom`` is used without

      ``--template`` (Lukáš Lalinský)

    * Don't raise UnavailableFeature during test setup when medusa is not

      available or tearDown is never called leading to nasty side effects.

      (#137823, Vincent Ladeuil)

    * If a plugin's test suite cannot be loaded, for example because of a syntax

      error in the tests, then ``selftest`` fails, rather than just printing 

      a warning.  (Martin Pool, #189771)

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

      help topic. (Alexander Belchenko, #181842)

    * New methods ``push_log_file`` and ``pop_log_file`` to intercept messages:

      popping the log redirection now precisely restores the previous state,

      which makes it easier to use bzr log output from other programs.

      TestCaseInTempDir no longer depends on a log redirection being established

      by the test framework, which lets bzr tests cleanly run from a normal

      unittest runner.

      (#124153, #124849, Martin Pool, Jonathan Lange)

    * ``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)

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

      SFTPTransport and HttpTransportBase.  (Andrew Bennetts)

    * 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)

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)
