Log Message:
bzr 1.9 2008-11-07
------------------

This release of Bazaar adds a new repository format, ``1.9``, with smaller
and more efficient index files.  This format can be specified when
creating a new repository, or used to losslessly upgrade an existing
repository.  bzr 1.9 also speeds most operations over the smart server
protocol, makes annotate faster, and uses less memory when making
checkouts or pulling large amounts of data.

  BUG FIXES:

   * Fix "invalid property value 'branch-nick' for None" regression with
     branches bound to svn branches.  (Martin Pool, #293440)

   * Fix SSL/https on Python2.6.  (Vincent Ladeuil, #293054)

   * ``SFTPTransport.readv()`` had a bug when requests were out-of-order.
     This only triggers some-of-the-time on Knit format repositories.
     (John Arbash Meinel, #293746)

bzr 1.9rc1 2008-10-31
---------------------

  NEW FEATURES:

    * New Branch hook ``transform_fallback_location`` allows a function to
      be called when looking up the stacked source. (Michael Hudson)

    * New repository formats ``1.9`` and ``1.9-rich-root``. These have all
      the functionality of ``1.6``, but use the new btree indexes.
      These indexes are both smaller and faster for access to historical
      information.  (John Arbash Meinel)

  IMPROVEMENTS:

    * ``BTreeIndex`` code now is able to prefetch extra pages to help tune
      the tradeoff between bandwidth and latency. Should be tuned
      appropriately to not impact commands which need minimal information,
      but provide a significant boost to ones that need more context. Only
      has a direct impact on the ``--development2`` format which uses
      btree's for the indexes. (John Arbash Meinel)

    * ``bzr dump-btree`` is a hidden command introduced to allow dumping
      the contents of a compressed btree file.  (John Arbash Meinel)

    * ``bzr pack`` now tells the index builders to optimize for size. For
      btree index repositories, this can save 25% of the index size
      (mostly in the text indexes). (John Arbash Meinel)

    * ``bzr push`` to an existing branch or repository on a smart server
      is faster, due to Bazaar making more use of the ``get_parent_map``
      RPC when querying the remote branch's revision graph.
      (Andrew Bennetts)

    * default username for bzr+ssh and sftp can be configured in
      authentication.conf. (Aaron Bentley)

    * launchpad-login now provides a default username for bzr+ssh and sftp
      URLs, allowing username-free URLs to work for everyone. (Aaron Bentley)

    * ``lp:`` lookups no longer include usernames, making them shareable and
      shorter. (Aaron Bentley)

    * New ``PackRepository.autopack`` smart server RPC, which does
      autopacking entirely on the server.  This is much faster than
      autopacking via plain file methods, which downloads a large amount
      of pack data and then re-uploads the same pack data into a single
      file.  This fixes a major (although infrequent) cause of lengthy
      delays when using a smart server.  For example, pushing the 10th
      revision to a repository with 9 packs now takes 44 RPCs rather than
      179, and much less bandwidth too.  This requires Bazaar 1.9 on both
      the client and the server, otherwise the client will fallback to the
      slower method.  (Andrew Bennetts)

  BUG FIXES:

    * A failure to load a plugin due to an IncompatibleAPI exception is
      now correctly reported. (Robert Collins, #279451)

    * API versioning support now has a multiple-version checking api
      ``require_any_api``. (Robert Collins, #279447)

    * ``bzr branch --stacked`` from a smart server to a standalone branch
      works again.  This fixes a regression in 1.7 and 1.8.
      (Andrew Bennetts, #270397)

    * ``bzr co`` uses less memory. It used to unpack the entire WT into
      memory before writing it to disk. This was a little bit faster, but
      consumed lots of memory. (John Arbash Meinel, #269456)

    * ``bzr missing --quiet`` no longer prints messages about whether
      there are missing revisions.  The exit code indicates whether there
      were or not.  (Martin Pool, #284748)

    * Fixes to the ``annotate`` code. The fast-path which re-used the
      stored deltas was accidentally disabled all the time, instead of
      only when a branch was stacked. Second, the code would accidentally
      re-use a delta even if it wasn't against the left-parent, this
      could only happen if ``bzr reconcile`` decided that the parent
      ordering was incorrect in the file graph.  (John Arbash Meinel)

    * "Permission denied" errors that occur when pushing a new branch to a
      smart server no longer cause tracebacks.  (Andrew Bennetts, #278673)

    * Some compatibility fixes for building the extensions with MSVC and
      for python2.4. (John Arbash Meinel, #277484)

    * The index logic is now able to reload the list of pack files if and
      index ends up disappearing. We still don't reload if the pack data
      itself goes missing after checking the index. This bug appears as a
      transient failure (file not found) when another process is writing
      to the repository.  (John Arbash Meinel, #153786)

    * ``bzr switch`` and ``bzr bind`` will now update the branch nickname if
      it was previously set. All checkouts will now refer to the bound branch
      for a nickname if one was not explicitly set.
      (Marius Kruger, #230903)

  DOCUMENTATION:

    * Improved hook documentation. (Michael Ernst)

  API CHANGES:

    * commands.plugins_cmds is now a CommandRegistry, not a dict.

  INTERNALS:

     * New AuthenticationConfig.set_credentials method allows easy programmatic
       configuration of authetication credentials.

bzr 1.8 2008-10-16
------------------

Bazaar 1.8 includes several fixes that improve working tree performance,
display of revision logs, and merges.  The bzr testsuite now passes on OS
X and Python 2.6, and almost completely passes on Windows.  The
smartserver code has gained several bug fixes and performance
improvements, and can now run server-side hooks within an http server.

  BUG FIXES:

   * Fix "Must end write group" error when another error occurs during
     ``bzr push``.  (Andrew Bennetts, #230902)

  PORTABILITY:

   * Some Pyrex versions require the WIN32 macro defined to compile on
     that platform.  (Alexander Belchenko, Martin Pool, #277481)

bzr 1.8rc1 2008-10-07
---------------------

  CHANGES:

    * ``bzr log file`` has been changed. It now uses a different method
      for determining which revisions to show as merging the changes to
      the file. It now only shows revisions which merged the change
      towards your mainline. This simplifies the output, makes it faster,
      and reduces memory consumption.  (John Arbash Meinel)

    * ``bzr merge`` now defaults to having ``--reprocess`` set, whenever
      ``--show-base`` is not supplied.  (John Arbash Meinel)

    * ``bzr+http//`` will now optionally load plugins and write logs on the
      server. (Marius Kruger)

    * ``bzrlib._dirstate_helpers_c.pyx`` does not compile correctly with
      Pyrex 0.9.4.1 (it generates C code which causes segfaults). We
      explicitly blacklist that version of the compiler for that
      extension. Packaged versions will include .c files created with
      pyrex >= 0.9.6 so it doesn't effect releases, only users running
      from the source tree. (John Arbash Meinel, #276868)

  FEATURES

    * bzr is now compatible with python-2.6. python-2.6 is not yet officially
      supported (nor released, tests were conducted with the dev version of
      python-2.6rc2), but all known problems have been fixed.  Feedback
      welcome.
      (Vincent Ladeuil, #269535)

  IMPROVEMENTS:

    * ``bzr annotate`` will now include uncommitted changes from the local
      working tree by default. Such uncommitted changes are given the
      revision number they would get if a commit was done, followed with a
      ? to indicate that its not actually known. (Robert Collins, #3439)

    * ``bzr branch`` now accepts a ``--standalone`` option, which creates a
      standalone branch regardless of the presence of shared repositories.
      (Daniel Watkins)

    * ``bzr push`` is faster in the case there are no new revisions to
      push.  It is also faster if there are no tags in the local branch.
      (Andrew Bennetts)

    * File changes during a commit will update the tree stat cache.
      (Robert Collins)

    * Location aliases can now accept a trailing path.  (Micheal Hudson)

    * New hooks ``Lock.hooks`` when LockDirs are acquired and released.
      (Robert Collins, MartinPool)

    * Switching in heavyweight checkouts uses the master branch's context, not
      the checkout's context.  (Adrian Wilkins)

    * ``status`` on large trees is now faster, due to optimisations in the
      walkdirs code. Of particular note, the walkdirs code now performs
      a temporary ``chdir()`` while reading a single directory; if your
      platform has non thread-local current working directories (and is
      not windows which has its own implementation), this may introduce a
      race condition during concurrent uses of bzrlib. The bzrlib CLI
      will not encounter this as it is single threaded for working tree
      operations. (Robert Collins)

    * The C extensions now build on python 2.4 (Robert Collins, #271939)

    * The ``-Dhpss`` debug flag now reports the number of smart server
      calls per medium to stderr.  This is in addition to the existing
      detailed logging to the .bzr.log trace file.  (Andrew Bennetts)

  BUG FIXES:

    * Avoid random failures arising from misinterpreted ``errno`` values
      in ``_readdir_pyx.read_dir``.
      (Martin Pool, #279381)

    * Branching from a shared repository on a smart server into a new
      repository now preserves the repository format.
      (Andrew Bennetts, #269214)

    * ``bzr log`` now accepts a ``--change`` option.
      (Vincent Ladeuil, #248427)

    * ``bzr missing`` now accepts an ``--include-merges`` option.
      (Vincent Ladeuil, #233817)

    * Don't try to filter (internally) '.bzr' from the files to be deleted if
      it's not there.
      (Vincent Ladeuil, #272648)

    * Fix '_in_buffer' AttributeError when using the -Dhpss debug flag.
      (Andrew Bennetts)

    * Fix TooManyConcurrentRequests errors caused by a connection failure
      when doing ``bzr pull`` or ``bzr merge`` from a ``bzr+ssh`` URL.
      (Andrew Bennetts, #246233)

    * Fixed ``bzr st -r branch:PATH_TO_BRANCH`` where the other branch
      is in a different repository than the current one.
      (Lukáš Lalinský, #144421)

    * Make the first line of the manpage preamble a comment again.
      (David Futcher, #242106)

    * Remove use of optional parameter in GSSAPI FTP support, since
      it breaks newer versions of Python-Kerberos. (Jelmer Vernooij)

    * The autopacking logic will now always create a single new pack from
      all of the content which it deems is worth moving. This avoids the
      'repack a single pack' bug and should result in better packing
      overall.  (John Arbash Meinel, #242510, #172644)

    * Trivial documentation fix.
      (John Arbash Meinel, #270471)

  DOCUMENTATION:

    * Explain revision/range identifiers. (Daniel Clemente)

  API CHANGES:

    * ``CommitBuilder.record_entry_contents`` returns one more element in
      its result tuple - an optional file system hash for the hash cache
      to use. (Robert Collins)

    * ``dirstate.DirState.update_entry`` will now only calculate the sha1
      of a file if it is likely to be needed in determining the output
      of iter_changes. (Robert Collins)

    * The PackRepository, RepositoryPackCollection, NewPack classes have a
      slightly changed interface to support different index types; as a
      result other users of these classes need to supply the index types
      they want. (Robert Collins)

  TESTING:

    * ``bzrlib.tests.repository_implementations`` has been renamed to
      ``bzrlib.tests.per_repository`` so that we have a common structure
      (and it is shorter). (John Arbash Meinel, #239343)

    * ``LocalTransport.abspath()`` now returns a drive letter if the
      transport has one, fixing numerous tests on Windows.
      (Mark Hammond)

    * PreviewTree is now tested via intertree_implementations.
      (Aaron Bentley)

    * The full test suite is passing again on OSX.
      (Guillermo Gonzalez, Vincent Ladeuil)

    * The full test suite passes when run with ``-Eallow_debug``.
      (Andrew Bennetts)

  INTERNALS:

    * A new hook, ``Branch.open``, has been added, which is called when
      branch objects are opened. (Robert Collins)

    * ``bzrlib.osutils._walkdirs_utf8`` has been refactored into common
      tree walking, and modular directory listing code to aid future
      performance optimisations and refactoring. (Robert Collins)

    * ``bzrlib.trace.debug_memory`` can be used to get a quick memory dump
      in the middle of processing. It only reports memory if
      ``/proc/PID/status`` is available. (John Arbash Meinel)

    * New method ``RevisionSpec.as_tree`` for representing the revision
      specifier as a revision tree object. (Lukáš Lalinský)

    * New race-free method on MutableTree ``get_file_with_stat`` for use
      when generating stat cache results. (Robert Collins)

    * New win32utils.get_local_appdata_location() provides access to a local
      directory for storing data.  (Mark Hammond)

    * To be compatible with python-2.6 a few new rules should be
      observed. 'message' attribute can't be used anymore in exception
      classes, 'sha' and 'md5' modules have been deprecated (use
      osutils.[md5|sha]), object__init__ and object.__new__ don't accept
      parameters anymore.
      (Vincent Ladeuil)

bzr 1.7.1 2008-10-01
--------------------

  No changes from 1.7.1rc1.

bzr 1.7.1rc1 2008-09-24
-----------------------

This release just includes an update to how the merge algorithm handles
file paths when we encounter complex history.

  FEATURES:

    * If we encounter a criss-cross in history, use information from
      direct Least Common Ancestors to resolve inventory shape (locations
      of files, adds, deletes, etc). This is similar in concept to using
      ``--lca`` for merging file texts, only applied to paths.
      (John Arbash Meinel)

bzr 1.7 2008-09-23
------------------

This release includes many bug fixes and a few performance and feature
improvements.  ``bzr rm`` will now scan for missing files and remove them,
like how ``bzr add`` scans for unknown files and adds them. A bit more
polish has been applied to the stacking code. The b-tree indexing code has
been brought in, with an eye on using it in a future repository format.
There are only minor installer changes since bzr-1.7rc2.

  FEATURES

    * Some small updates to the win32 installer. Include localization
      files found in plugins, and include the builtin distutils as part of
      packaging qbzr. (Mark Hammond)

bzr 1.7rc2 2008-09-17
---------------------

A few bug fixes from 1.7rc1. The biggest change is a new
``RemoteBranch.get_stacked_on_url`` rpc. This allows clients that are
trying to access a Stacked branch over the smart protocol, to properly
connect to the stacked-on location.

  BUG FIXES:

    * Branching from a shared repository on a smart server into a new
      repository now preserves the repository format.
      (Andrew Bennetts, #269214)

   * Branching from a stacked branch via ``bzr+ssh`` can properly connect
     to the stacked-on branch.  (Martin Pool, #261315)

    * ``bzr init`` no longer re-opens the BzrDir multiple times.
      (Vincent Ladeuil)

    * Fix '_in_buffer' AttributeError when using the -Dhpss debug flag.
      (Andrew Bennetts)

bzr 1.7rc1 2008-09-09
---------------------

This release candidate for bzr 1.7 has several bug fixes and a few
performance and feature improvements.  ``bzr rm`` will now scan for
missing files and remove them, like how ``bzr add`` scans for unknown
files and adds them. A bit more polish has been applied to the stacking
code. The b-tree indexing code has been brought in, with an eye on using
it in a future repository format.

  CHANGES:

    * ``bzr export`` can now export a subdirectory of a project.
      (Robert Collins)

    * ``bzr remove-tree`` will now refuse to remove a tree with uncommitted
      changes, unless the ``--force`` option is specified.
      (Lukáš Lalinský, #74101)

    * ``bzr rm`` will now scan for files that are missing and remove just
      them automatically, much as ``bzr add`` scans for new files that
      are not ignored and adds them automatically. (Robert Collins)

  FEATURES

    * Support for GSSAPI authentication when using FTP as documented in
      RFC2228. (Jelmer Vernooij, #49623)

    * Add support for IPv6 in the smart server. (Jelmer Vernooij, #165014)

  IMPROVEMENTS:

    * A url like ``log+file:///tmp`` will log all access to that Transport
      to ``.bzr.log``, which may help in debugging or profiling.
      (Martin Pool)

    * ``bzr branch`` and ``bzr push`` use the default stacking policy if the
      branch format supports it. (Aaron Bentley)

    * ``bzr init`` and ``bzr init-repo`` will now print out the same as
      ``bzr info`` if it completed successfully.
      (Marius Kruger)

    * ``bzr uncommit`` logs the old tip revision id, and displays how to
      restore the branch to that tip using ``bzr pull``.  This allows you
      to recover if you realize you uncommitted the wrong thing.
      (John Arbash Meinel)

    * Fix problems in accessing stacked repositories over ``bzr://``.
      (Martin Pool, #261315)

    * ``SFTPTransport.readv()`` was accidentally using ``list += string``,
      which 'works', but adds each character separately to the list,
      rather than using ``list.append(string)``. Fixing this makes the
      SFTP transport a little bit faster (~20%) and use a bit less memory.
      (John Arbash Meinel)

    * When reading index files, if we happen to read the whole file in a
      single request treat it as a ``_buffer_all`` request. This happens
      most often on small indexes over remote transports, where we default
      to reading 64kB. It saves a round trip for each small index during
      fetch operations. Also, if we have read more than 50% of an index
      file, trigger a ``_buffer_all`` on the next request. This works
      around some inefficiencies because reads don't fall neatly on page
      boundaries, so we would ignore those bytes, but request them again
      later. This could trigger a total read size of more than the whole
      file. (John Arbash Meinel)

  BUG FIXES:

    * ``bzr rm`` is now aliased to ``bzr del`` for the convenience of svn
      users. (Robert Collins, #205416)

    * Catch the infamous "select/poll returned error" which occurs when
      pycurl try to send a body request to an HTTP/1.0 server which has
      already refused to handle the request. (Vincent Ladeuil, #225020)

    * Fix ``ObjectNotLocked`` errors when using various commands
      (including ``bzr cat`` and ``bzr annotate``) in combination with a
      smart server URL.  (Andrew Bennetts, #237067)

    * ``FTPTransport.stat()`` would return ``0000`` as the permission bits
      for the containing ``.bzr/`` directory (it does not implement
      permissions). This would cause us to set all subdirectories to
      ``0700`` and files to ``0600`` rather than leaving them unmodified.
      Now we ignore ``0000`` as the permissions and assume they are
      invalid. (John Arbash Meinel, #259855)

    * Merging from a previously joined branch will no longer cause
      a traceback. (Jelmer Vernooij, #203376)

    * Pack operations on windows network shares will work even with large
      files. (Robert Collins, #255656)

    * Running ``bzr st PATH_TO_TREE`` will no longer suppress merge
      status. Status is also about 7% faster on mozilla sized trees
      when the path to the root of the tree has been given. Users of
      the internal ``show_tree_status`` function should be aware that
      the show_pending flag is now authoritative for showing pending
      merges, as it was originally. (Robert Collins, #225204)

    * Set valid default _param_name for Option so that ListOption can embed
      '-' in names. (Vincent Ladeuil, #263249)

    * Show proper error rather than traceback when an unknown revision
      id is specified to ``bzr cat-revision``. (Jelmer Vernooij, #175569)

    * Trailing text in the dirstate file could cause the C dirstate parser
      to try to allocate an invalid amount of memory. We now properly
      check and test for parsing a dirstate with invalid trailing data.
      (John Arbash Meinel, #186014)

    * Unexpected error responses from a smart server no longer cause the
      client to traceback.  (Andrew Bennetts, #263527)

    * Use a Windows api function to get a Unicode host name, rather than
      assuming the host name is ascii.
      (Mark Hammond, John Arbash Meinel, #256550)

    * ``WorkingTree4`` trees will now correctly report missing-and-new
      paths in the output of ``iter_changes``. (Robert Collins)

  DOCUMENTATION:

    * Updated developer documentation.  (Martin Pool)

  API CHANGES:

    * Exporters now take 4 parameters. (Robert Collins)

    * ``Tree.iter_changes`` will now return False for the content change
      field when a file is missing in the basis tree and not present in
      the target tree. Previously it returned True unconditionally.
      (Robert Collins)

    * The deprecated ``Branch.abspath`` and unimplemented
      ``Branch.rename_one`` and ``Branch.move`` were removed. (Jelmer Vernooij)

    * BzrDir.clone_on_transport implementations must now accept a stacked_on
      parameter.  (Aaron Bentley)

    * BzrDir.cloning_metadir implementations must now take a require_stacking
      parameter.  (Aaron Bentley)

  TESTING:

    * ``addCleanup`` now takes ``*arguments`` and ``**keyword_arguments``
      which are then passed to the cleanup callable as it is run. In
      addition, addCleanup no longer requires that the callables passed to
      it be unique. (Jonathan Lange)

    * Fix some tests that fail on Windows because files are deleted while
      still in use.
      (Mark Hammond)

    * ``selftest``'s ``--starting-with`` option can now use predefined
      prefixes so that one can say ``bzr selftest -s bp.loom`` instead of
      ``bzr selftest -s bzrlib.plugins.loom``. (Vincent Ladeuil)

    * ``selftest``'s ``--starting-with`` option now accepts multiple values.
      (Vincent Ladeuil)

  INTERNALS:

    * A new plugin interface, ``bzrlib.log.log_adapters``, has been added.
      This allows dynamic log output filtering by plugins.
      (Robert Collins)

    * ``bzrlib.btree_index`` is now available, providing a b-tree index
      layer. The design is memory conservative (limited memory cache),
      faster to seek (approx 100 nodes per page, gives 100-way fan out),
      and stores compressed pages allowing more keys per page.
      (Robert Collins, John Arbash Meinel)

    * ``bzrlib.diff.DiffTree.show_diff`` now skips changes where the kind
      is unknown in both source and target.
      (Robert Collins, Aaron Bentley)

    * ``GraphIndexBuilder.add_node`` and ``BTreeBuilder`` have been
      streamlined a bit. This should make creating large indexes faster.
      (In benchmarking, it now takes less time to create a BTree index than
      it takes to read the GraphIndex one.) (John Arbash Meinel)

    * Mail clients for `bzr send` are now listed in a registry.  This
      allows plugins to add new clients by registering them with
      ``bzrlib.mail_client.mail_client_registry``.  All of the built-in
