IN DEVELOPMENT

  BUGFIXES:

    * ``bzr init`` should connect to the remote location one time only.  We

      have been connecting several times because we forget to pass around the

      Transport object. This modifies ``BzrDir.create_branch_convenience``,

      so that we can give it the Transport we already have.

      (John Arbash Meinel, Vincent Ladeuil, #111702)

    * Get rid of sftp connection cache (get rid of the FTP one too).

      (Vincent Ladeuil, #43731)

    * bzr branch {local|remote} remote don't try to create a working tree

      anymore.

      (Vincent Ladeuil, #112173)

    * All identified multiple connections for a single bzr command have been

      fixed. See bzrlib/tests/commands directory.

      (Vincent Ladeuil)

    * ``bzr rm`` now does not insist on ``--force`` to delete files that

      have been renamed but not otherwise modified.  (Marius Kruger,

      #111664)

    * ``bzr selftest --bench`` no longer emits deprecation warnings

      (Lukáš Lalinský)

  IMPROVEMENTS:

    * Don't show "dots" progress indicators when run non-interactively, such

      as from cron.  (Martin Pool)

    * ``info`` now formats locations more nicely and lists "submit" and

      "public" branches (Aaron Bentley)

    * New ``pack`` command that will trigger database compression within

      the repository (Robert Collins)

    * Implement ``_KnitIndex._load_data`` in a pyrex extension. The pyrex

      version is approximately 2-3x faster at parsing a ``.kndx`` file.

      Which yields a measurable improvement for commands which have to

      read from the repository, such as a 1s => 0.75s improvement in

      ``bzr diff`` when there are changes to be shown.  (John Arbash Meinel)

    * Merge is now faster.  Depending on the scenario, it can be more than 2x

      faster. (Aaron Bentley)

    * Give a clearer warning, and allow ``python setup.py install`` to

      succeed even if pyrex is not available.

      (John Arbash Meinel)

    * ``DirState._read_dirblocks`` now has an optional Pyrex

      implementation. This improves the speed of any command that has to

      read the entire DirState. (``diff``, ``status``, etc, improve by

      about 10%).

      ``bisect_dirblocks`` has also been improved, which helps all

      ``_get_entry`` type calls (whenever we are searching for a

      particular entry in the in-memory DirState).

      (John Arbash Meinel)

    * ``bzr pull`` and ``bzr push`` no longer do a complete walk of the 

      branch revision history for ui display unless -v is supplied.

      (Robert Collins)

    * ``bzr log -rA..B`` output shifted to the left margin if the log only 

      contains merge revisions. (Kent Gibson) 

    * The ``plugins`` command is now public with improved help.

      (Ian Clatworthy)

    * New bundle and merge directive formats are faster to generate, and

      more robust against email mangling.  (Aaron Bentley)

    * Annotate merge now works when there are local changes. (Aaron Bentley)

  LIBRARY API BREAKS:

    * Deprecated dictionary ``bzrlib.option.SHORT_OPTIONS`` removed.

      Options are now required to provide a help string and it must

      comply with the style guide by being one or more sentences with an

      initial capital and final period. (Martin Pool)

  INTERNALS:

    * merge now uses ``iter_changes`` to calculate changes, which makes room for

      future performance increases.  It is also more consistent with other

      operations that perform comparisons, and reduces reliance on

      Tree.inventory.  (Aaron Bentley)

    * Refactoring of transport classes connected to a remote server.

      ConnectedTransport is a new class that serves as a basis for all

      transports needing to connect to a remote server.  transport.split_url

      have been deprecated, use the static method on the object instead. URL

      tests have been refactored too.

      (Vincent Ladeuil)

    * Better connection sharing for ConnectedTransport objects.

      transport.get_transport() now accepts a 'possible_transports' parameter.

      If a newly requested transport can share a connection with one of the

      list, it will.

      (Vincent Ladeuil)

    * Most functions now accept ``bzrlib.revision.NULL_REVISION`` to indicate

      the null revision, and consider using ``None`` for this purpose

      deprecated.  (Aaron Bentley)

    * New ``index`` module with abstract index functionality. This will be

      used during the planned changes in the repository layer. Currently the

      index layer provides a graph aware immutable index, a builder for the

      same index type to allow creating them, and finally a composer for

      such indices to allow the use of many indices in a single query. The

      index performance is not optimised, however the API is stable to allow

      development on top of the index. (Robert Collins)

    * ``bzrlib.dirstate.cmp_by_dirs`` can be used to compare two paths by

      their directory sections. This is equivalent to comparing

      ``path.split('/')``, only without having to split the paths.

      This has a Pyrex implementation available.

      (John Arbash Meinel)

    * New transport decorator 'unlistable+' which disables the list_dir

      functionality for testing.

    * New ``file_names.FileNames`` support class which mananges names

      for unlistable transport situations. (Robert Collins)

    * Deprecated ``change_entry`` in transform.py. (Ian Clatworthy)

    * RevisionTree.get_weave is now deprecated.  Tree.plan_merge is now used

      for performing annotate-merge.  (Aaron Bentley)

    * New EmailMessage class to create email messages. (Adeodato Simó)

  TESTING:

    * Remove selftest ``--clean-output``, ``--numbered-dirs`` and

      ``--keep-output`` options, which are obsolete now that tests

      are done within directories in $TMPDIR.  (Martin Pool)

    * The SSH_AUTH_SOCK environment variable is now reset to avoid 

      interaction with any running ssh agents.  (Jelmer Vernooij, #125955)

bzr 0.18  2007-07-17

  BUGFIXES:

    * Fix 'bzr add' crash under Win32 (Kuno Meyer)

bzr 0.18rc1  2007-07-10

  BUGFIXES:

    * Do not suppress pipe errors, etc. in non-display commands

      (Alexander Belchenko, #87178)

    * Display a useful error message when the user requests to annotate

      a file that is not present in the specified revision.

      (James Westby, #122656)

    * Commands that use status flags now have a reference to 'help

      status-flags'.  (Daniel Watkins, #113436)

    * Work around python-2.4.1 inhability to correctly parse the

      authentication header.

      (Vincent Ladeuil, #121889)

    * Use exact encoding for merge directives. (Adeodato Simó, #120591)

    * Fix tempfile permissions error in smart server tar bundling under

      Windows. (Martin_, #119330)

    * Fix detection of directory entries in the inventory. (James Westby)

    * Fix handling of http code 400: Bad Request When issuing too many ranges.

      (Vincent Ladeuil, #115209)

    * Issue a CONNECT request when connecting to an https server

      via a proxy to enable SSL tunneling.

     (Vincent Ladeuil, #120678)

    * Fix ``bzr log -r`` to support selecting merge revisions, both 

      individually and as part of revision ranges.

      (Kent Gibson, #4663)

    * Don't leave cruft behind when failing to acquire a lockdir.

      (Martin Pool, #109169)

    * Don't use the '-f' strace option during tests.

      (Vincent Ladeuil, #102019).

    * Warn when setting ``push_location`` to a value that will be masked by

      locations.conf.  (Aaron Bentley, #122286)

    * Fix commit ordering in corner case (Aaron Bentley, #94975)

    *  Make annotate behave in a non-ASCII world (Adeodato Simó).

  IMPROVEMENTS:

    * The --lsprof-file option now dumps a text rendering of the profiling

      information if the filename ends in ".txt". It will also convert the

      profiling information to a format suitable for KCacheGrind if the

      output filename ends in ".callgrind". Fixes to the lsprofcalltree

      conversion process by Jean Paul Calderone and Itamar were also merged.

      See http://ddaa.net/blog/python/lsprof-calltree. (Ian Clatworthy)

    * ``info`` now defaults to non-verbose mode, displaying only paths and

      abbreviated format info.  ``info -v`` displays all the information

      formerly displayed by ``info``.  (Aaron Bentley, Adeodato Simó)

    * ``bzr missing`` now has better option names ``--this`` and ``--other``.

      (Elliot Murphy)

    * The internal ``weave-list`` command has become ``versionedfile-list``,

      and now lists knits as well as weaves.  (Aaron Bentley)

    * Automatic merge base selection uses a faster algorithm that chooses

      better bases in criss-cross merge situations (Aaron Bentley)

    * Progress reporting in ``commit`` has been improved. The various logical

      stages are now reported on as follows, namely:

      * Collecting changes [Entry x/y] - Stage n/m

      * Saving data locally - Stage n/m

      * Uploading data to master branch - Stage n/m

      * Updating the working tree - Stage n/m

      * Running post commit hooks - Stage n/m

      If there is no master branch, the 3rd stage is omitted and the total

      number of stages is adjusted accordingly.

      Each hook that is run after commit is listed with a name (as hooks

      can be slow it is useful feedback).

      (Ian Clatworthy, Robert Collins)

    * Various operations that are now faster due to avoiding unnecessary

      topological sorts. (Aaron Bentley)

    * Make merge directives robust against broken bundles. (Aaron Bentley)

    * The lsprof filename note is emitted via trace.note(), not standard

      output.  (Aaron Bentley)

    * ``bzrlib`` now exports explicit API compatibility information to assist

      library users and plugins. See the ``bzrlib.api`` module for details.

      (Robert Collins)

    * Remove unnecessary lock probes when acquiring a lockdir.

      (Martin Pool)

    * ``bzr --version`` now shows the location of the bzr log file, which

      is especially useful on Windows.  (Martin Pool)

    * -D now supports hooks to get debug tracing of hooks (though its currently

      minimal in nature). (Robert Collins)

    * Long log format reports deltas on merge revisions. 

      (John Arbash Meinel, Kent Gibson)

    * Make initial push over ftp more resilient. (John Arbash Meinel)

    * Print a summary of changes for update just like pull does.

      (Daniel Watkins, #113990)

    * Add a -Dhpss option to trace smart protocol requests and responses.

      (Andrew Bennetts)

  LIBRARY API BREAKS:

    * Testing cleanups - 

     ``bzrlib.repository.RepositoryTestProviderAdapter`` has been moved

      to ``bzrlib.tests.repository_implementations``;

      ``bzrlib.repository.InterRepositoryTestProviderAdapter`` has been moved

      to ``bzrlib.tests.interrepository_implementations``;

      ``bzrlib.transport.TransportTestProviderAdapter`` has moved to 

      ``bzrlib.tests.test_transport_implementations``.

      ``bzrlib.branch.BranchTestProviderAdapter`` has moved to

      ``bzrlib.tests.branch_implementations``.

      ``bzrlib.bzrdir.BzrDirTestProviderAdapter`` has moved to 

      ``bzrlib.tests.bzrdir_implementations``.

      ``bzrlib.versionedfile.InterVersionedFileTestProviderAdapter`` has moved

      to ``bzrlib.tests.interversionedfile_implementations``.

      ``bzrlib.store.revision.RevisionStoreTestProviderAdapter`` has moved to

      ``bzrlib.tests.revisionstore_implementations``.

      ``bzrlib.workingtree.WorkingTreeTestProviderAdapter`` has moved to

      ``bzrlib.tests.workingtree_implementations``.

      These changes are an API break in the testing infrastructure only.

      (Robert Collins)

    * Relocate TestCaseWithRepository to be more central. (Robert Collins)

    * ``bzrlib.add.smart_add_tree`` will no longer perform glob expansion on

      win32. Callers of the function should do this and use the new

      ``MutableTree.smart_add`` method instead. (Robert Collins)

    * ``bzrlib.add.glob_expand_for_win32`` is now

      ``bzrlib.win32utils.glob_expand``.  (Robert Collins)

    * ``bzrlib.add.FastPath`` is now private and moved to 

      ``bzrlib.mutabletree._FastPath``. (Robert Collins, Martin Pool)

    * ``LockDir.wait`` removed.  (Martin Pool)

    * The ``SmartServer`` hooks API has changed for the ``server_started`` and

      ``server_stopped`` hooks. The first parameter is now an iterable of

      backing URLs rather than a single URL. This is to reflect that many

      URLs may map to the external URL of the server. E.g. the server interally

      may have a chrooted URL but also the local file:// URL will be at the 

      same location. (Robert Collins)

  INTERNALS:

    * New SMTPConnection class to unify email handling.  (Adeodato Simó)

    * Fix documentation of BzrError. (Adeodato Simó)

    * Make BzrBadParameter an internal error. (Adeodato Simó)

    * Remove use of 'assert False' to raise an exception unconditionally.

      (Martin Pool)

    * Give a cleaner error when failing to decode knit index entry.

      (Martin Pool)

    * TreeConfig would mistakenly search the top level when asked for options

      from a section. It now respects the section argument and only

      searches the specified section. (James Westby)

    * Improve ``make api-docs`` output. (John Arbash Meinel)

    * Use os.lstat rather than os.stat for osutils.make_readonly and

      osutils.make_writeable. This makes the difftools plugin more

      robust when dangling symlinks are found. (Elliot Murphy)

    * New ``-Dlock`` option to log (to ~/.bzr.log) information on when 

      lockdirs are taken or released.  (Martin Pool)

    * ``bzrlib`` Hooks are now nameable using ``Hooks.name_hook``. This 

      allows a nicer UI when hooks are running as the current hook can

      be displayed. (Robert Collins)

    * ``Transport.get`` has had its interface made more clear for ease of use.

      Retrieval of a directory must now fail with either 'PathError' at open

      time, or raise 'ReadError' on a read. (Robert Collins)

    * New method ``_maybe_expand_globs`` on the ``Command`` class for 

      dealing with unexpanded glob lists - e.g. on the win32 platform. This

      was moved from ``bzrlib.add._prepare_file_list``. (Robert Collins)

    * ``bzrlib.add.smart_add`` and ``bzrlib.add.smart_add_tree`` are now

      deprecated in favour of ``MutableTree.smart_add``. (Robert Collins,

      Martin Pool)

    * New method ``external_url`` on Transport for obtaining the url to

      hand to external processes. (Robert Collins)

    * Teach windows installers to build pyrex/C extensions.

      (Alexander Belchenko)

  TESTING:

    * Removed the ``--keep-output`` option from selftest and clean up test

      directories as they're used.  This reduces the IO load from 

      running the test suite and cuts the time by about half.

      (Andrew Bennetts, Martin Pool)

    * Add scenarios as a public attribute on the TestAdapter classes to allow

      modification of the generated scenarios before adaption and easier

      testing. (Robert Collins)

    * New testing support class ``TestScenarioApplier`` which multiplies

      out a single teste by a list of supplied scenarios. (RobertCollins)

    * Setting ``repository_to_test_repository`` on a repository_implementations

      test will cause it to be called during repository creation, allowing the

      testing of repository classes which are not based around the Format

      concept. For example a repository adapter can be tested in this manner,

      by altering the repository scenarios to include a scenario that sets this

      attribute during the test parameterisation in

      ``bzrlib.tests.repository.repository_implementations``. (Robert Collins)

    * Clean up many of the APIs for blackbox testing of Bazaar.  The standard 

      interface is now self.run_bzr.  The command to run can be passed as

      either a list of parameters, a string containing the command line, or

      (deprecated) varargs parameters.  (Martin Pool)

    * The base TestCase now isolates tests from -D parameters by clearing

      ``debug.debug_flags`` and restores it afterwards. (Robert Collins)

    * Add a relpath parameter to get_transport methods in test framework to

      avoid useless cloning.

      (Vincent Ladeuil, #110448)

bzr 0.17  2007-06-18

  BUGFIXES:

    * Fix crash of commit due to wrong lookup of filesystem encoding.

      (Colin Watson, #120647)

    * Revert logging just to stderr in commit as broke unicode filenames.

      (Aaron Bentley, Ian Clatworthy, #120930)

bzr 0.17rc1  2007-06-12

  NOTES WHEN UPGRADING:

    * The kind() and is_executable() APIs on the WorkingTree interface no

      longer implicitly (read) locks and unlocks the tree. This *might*

      impact some plug-ins and tools using this part of the API. If you find

      an issue that may be caused by this change, please let us know,

      particularly the plug-in/tool maintainer. If encountered, the API

      fix is to surround kind() and is_executable() calls with lock_read()

      and unlock() like so::

        work_tree.lock_read()

        try:

            kind = work_tree.kind(...)

        finally:

            work_tree.unlock()

  INTERNALS:

    * Rework of LogFormatter API to provide beginning/end of log hooks and to

      encapsulate the details of the revision to be logged in a LogRevision

      object.

      In long log formats, merge revision ids are only shown when --show-ids

      is specified, and are labelled "revision-id:", as per mainline

      revisions, instead of "merged:". (Kent Gibson)

    * New ``BranchBuilder`` API which allows the construction of particular

      histories quickly. Useful for testing and potentially other applications

      too. (Robert Collins)

  IMPROVEMENTS:

    * There are two new help topics, working-trees and repositories that

      attempt to explain these concepts. (James Westby, John Arbash Meinel,

      Aaron Bentley)

    * Added ``bzr log --limit`` to report a limited number of revisions.

      (Kent Gibson, #3659)

    * Revert does not try to preserve file contents that were originally

      produced by reverting to a historical revision.  (Aaron Bentley)

    * ``bzr log --short`` now includes ``[merge]`` for revisions which

      have more than one parent. This is a small improvement to help

      understanding what changes have occurred

      (John Arbash Meinel, #83887)

    * TreeTransform avoids many renames when contructing large trees,

      improving speed.  3.25x speedups have been observed for construction of

      kernel-sized-trees, and checkouts are 1.28x faster.  (Aaron Bentley)

    * Commit on large trees is now faster. In my environment, a commit of

      a small change to the Mozilla tree (55k files) has dropped from

      66 seconds to 32 seconds. For a small tree of 600 files, commit of a

      small change is 33% faster. (Ian Clatworthy)

    * New --create-prefix option to bzr init, like for push.  (Daniel Watkins,

      #56322)

  BUGFIXES:

    * ``bzr push`` should only connect to the remote location one time.

      We have been connecting 3 times because we forget to pass around

      the Transport object. This adds ``BzrDir.clone_on_transport()``, so

      that we can pass in the Transport that we already have.

      (John Arbash Meinel, #75721)

    * ``DirState.set_state_from_inventory()`` needs to properly order

      based on split paths, not just string paths.

      (John Arbash Meinel, #115947)

    * Let TestUIFactoy encode the password prompt with its own stdout.

      (Vincent Ladeuil, #110204)

    * pycurl should take use the range header that takes the range hint

      into account.

      (Vincent Ladeuil, #112719)

    * WorkingTree4.get_file_sha1 no longer raises an exception when invoked

      on a missing file.  (Aaron Bentley, #118186)

    * WorkingTree.remove works correctly with tree references, and when pwd is

      not the tree root. (Aaron Bentley)

    * Merge no longer fails when a file is renamed in one tree and deleted

      in the other. (Aaron Bentley, #110279)

    * ``revision-info`` now accepts dotted revnos, doesn't require a tree,

      and defaults to the last revision (Matthew Fuller, #90048)

    * Tests no longer fail when BZR_REMOTE_PATH is set in the environment.

      (Daniel Watkins, #111958)

    * ``bzr branch -r revid:foo`` can be used to branch any revision in

      your repository. (Previously Branch6 only supported revisions in your

      mainline). (John Arbash Meinel, #115343)

bzr 0.16  2007-05-07

  BUGFIXES:

    * Handle when you have 2 directories with similar names, but one has a

      hyphen. (``'abc'`` versus ``'abc-2'``). The WT4._iter_changes

      iterator was using direct comparison and ``'abc/a'`` sorts after

      ``'abc-2'``, but ``('abc', 'a')`` sorts before ``('abc-2',)``.

      (John Arbash Meinel, #111227)

    * Handle when someone renames a file on disk without telling bzr.

      Previously we would report the first file as missing, but not show

      the new unknown file. (John Arbash Meinel, #111288)

    * Avoid error when running hooks after pulling into or pushing from

      a branch bound to a smartserver branch.  (Martin Pool, #111968)

  IMPROVEMENTS:

    * Move developer documentation to doc/developers/. This reduces clutter in

      the root of the source tree and allows HACKING to be split into multiple

      files. (Robert Collins, Alexander Belchenko)

    * Clean up the ``WorkingTree4._iter_changes()`` internal loops as well as

      ``DirState.update_entry()``. This optimizes the core logic for ``bzr

      diff`` and ``bzr status`` significantly improving the speed of

      both. (John Arbash Meinel)

bzr 0.16rc2  2007-04-30

  BUGFIXES:

    * Handle the case when you delete a file, and then rename another file

      on top of it. Also handle the case of ``bzr rm --keep foo``. ``bzr

      status`` should show the removed file and an unknown file in its

      place. (John Arbash Meinel, #109993)

    * Bundles properly read and write revision properties that have an

      empty value. And when the value is not ASCII.

      (John Arbash Meinel, #109613)

    * Fix the bzr commit message to be in text mode.

      (Alexander Belchenko, #110901)

    * Also handle when you rename a file and create a file where it used

      to be. (John Arbash Meinel, #110256)

    * ``WorkingTree4._iter_changes`` should not descend into unversioned

      directories. (John Arbash Meinel, #110399)

bzr 0.16rc1  2007-04-26

  NOTES WHEN UPGRADING:

    * ``bzr remove`` and ``bzr rm`` will now remove the working file, if

      it could be recovered again.

      This has been done for consistency with svn and the unix rm command.

      The old ``remove`` behaviour has been retained in the new option

      ``bzr remove --keep``, which will just stop versioning the file,

      but not delete it.

      ``bzr remove --force`` have been added which will always delete the

      files.

      ``bzr remove`` is also more verbose.

      (Marius Kruger, #82602)

  IMPROVEMENTS:

    * Merge directives can now be supplied as input to `merge` and `pull`,

      like bundles can.  (Aaron Bentley)

    * Sending the SIGQUIT signal to bzr, which can be done on Unix by

      pressing Control-Backslash, drops bzr into a debugger.  Type ``'c'``

      to continue.  This can be disabled by setting the environment variable

      ``BZR_SIGQUIT_PDB=0``.  (Martin Pool)

    * selftest now supports --list-only to list tests instead of running

      them. (Ian Clatworthy)

    * selftest now supports --exclude PATTERN (or -x PATTERN) to exclude

      tests with names that match that regular expression.

      (Ian Clatworthy, #102679)

    * selftest now supports --randomize SEED to run tests in a random order.

      SEED is typically the value 'now' meaning 'use the current time'.

      (Ian Clatworthy, #102686)

    * New option ``--fixes`` to commit, which stores bug fixing annotations as

      revision properties. Built-in support for Launchpad, Debian, Trac and

      Bugzilla bug trackers. (Jonathan Lange, James Henstridge, Robert Collins)

    * New API, ``bzrlib.bugtracker.tracker_registry``, for adding support for

      other bug trackers to ``fixes``. (Jonathan Lange, James Henstridge,

      Robert Collins)

    * ``selftest`` has new short options ``-f`` and ``-1``.  (Martin

      Pool)

    * ``bzrlib.tsort.MergeSorter`` optimizations. Change the inner loop

      into using local variables instead of going through ``self._var``.

      Improves the time to ``merge_sort`` a 10k revision graph by

      approximately 40% (~700->400ms).  (John Arbash Meinel)

    * ``make docs`` now creates a man page at ``man1/bzr.1`` fixing bug 107388.

      (Robert Collins)

    * ``bzr help`` now provides cross references to other help topics using

      the _see_also facility on command classes. Likewise the bzr_man

      documentation, and the bzr.1 man page also include this information.

      (Robert Collins)

    * Tags are now included in logs, that use the long log formatter. 

      (Erik Bågfors, Alexander Belchenko)

    * ``bzr help`` provides a clearer message when a help topic cannot be

      found. (Robert Collins, #107656)

    * ``bzr help`` now accepts optional prefixes for command help. The help

      for all commands can now be found at ``bzr help commands/COMMANDNAME``
