bzr 0.8
#######

:Released:  2006-05-08

Notes When Upgrading
********************

Release 0.8 of bzr introduces a new format for history storage, called
'knit', as an evolution of to the 'weave' format used in 0.7.  Local
and remote operations are faster using knits than weaves.  Several
operations including 'init', 'init-repo', and 'upgrade' take a
--format option that controls this.  Branching from an existing branch
will keep the same format.

It is possible to merge, pull and push between branches of different
formats but this is slower than moving data between homogenous
branches.  It is therefore recommended (but not required) that you
upgrade all branches for a project at the same time.  Information on
formats is shown by 'bzr info'.

bzr 0.8 now allows creation of 'repositories', which hold the history
of files and revisions for several branches.  Previously bzr kept all
the history for a branch within the .bzr directory at the root of the
branch, and this is still the default.  To create a repository, use
the new 'bzr init-repo' command.  Branches exist as directories under
the repository and contain just a small amount of information
indicating the current revision of the branch.

bzr 0.8 also supports 'checkouts', which are similar to in cvs and
subversion.  Checkouts are associated with a branch (optionally in a
repository), which contains all the historical information.  The
result is that a checkout can be deleted without losing any
already-committed revisions.  A new 'update' command is also available.

Repositories and checkouts are not supported with the 0.7 storage
format.  To use them you must upgrad to either knits, or to the
'metaweave' format, which uses weaves but changes the .bzr directory
arrangement.


Improvements
************

* SFTP paths can now be relative, or local, according to the lftp
  convention. Paths now take the form::

      sftp://user:pass@host:port/~/relative/path
      or
      sftp://user:pass@host:port/absolute/path

* The FTP transport now tries to reconnect after a temporary
  failure. FTP put is made atomic. (Matthieu Moy)

* The FTP transport now maintains a pool of connections, and
  reuses them to avoid multiple connections to the same host (like
  SFTP did). (Daniel Silverstone)

* The ``bzr_man.py`` file has been removed. To create the man page now,
  use ``./generate_docs.py man``. The new program can also create other files.
  Run ``python generate_docs.py --help`` for usage information.
  (Hans Ulrich Niedermann & James Blackwell).

* Man Page now gives full help (James Blackwell).
  Help also updated to reflect user config now being stored in .bazaar
  (Hans Ulrich Niedermann)

* It's now possible to set aliases in bazaar.conf (Erik Bågfors)

* Pull now accepts a --revision argument (Erik Bågfors)

* ``bzr re-sign`` now allows multiple revisions to be supplied on the command
  line. You can now use the following command to sign all of your old
  commits::

    find .bzr/revision-store// -name my@email-* \
      | sed 's/.*\/\/..\///' \
      | xargs bzr re-sign

* Upgrade can now upgrade over the network. (Robert Collins)

* Two new commands 'bzr checkout' and 'bzr update' allow for CVS/SVN-alike
  behaviour.  By default they will cache history in the checkout, but
  with --lightweight almost all data is kept in the master branch.
  (Robert Collins)

* 'revert' unversions newly-versioned files, instead of deleting them.

* 'merge' is more robust.  Conflict messages have changed.

* 'merge' and 'revert' no longer clobber existing files that end in '~' or
  '.moved'.

* Default log format can be set in configuration and plugins can register
  their own formatters. (Erik Bågfors)

* New 'reconcile' command will check branch consistency and repair indexes
  that can become out of sync in pre 0.8 formats. (Robert Collins,
  Daniel Silverstone)

* New 'bzr init --format' and 'bzr upgrade --format' option to control
  what storage format is created or produced.  (Robert Collins,
  Martin Pool)

* Add parent location to 'bzr info', if there is one.  (Olaf Conradi)

* New developer commands 'weave-list' and 'weave-join'.  (Martin Pool)

* New 'init-repository' command, plus support for repositories in 'init'
  and 'branch' (Aaron Bentley, Erik Bågfors, Robert Collins)

* Improve output of 'info' command. Show all relevant locations related to
  working tree, branch and repository. Use kibibytes for binary quantities.
  Fix off-by-one error in missing revisions of working tree.  Make 'info'
  work on branches, repositories and remote locations.  Show locations
  relative to the shared repository, if applicable.  Show locking status
  of locations.  (Olaf Conradi)

* Diff and merge now safely handle binary files. (Aaron Bentley)

* 'pull' and 'push' now normalise the revision history, so that any two
  branches with the same tip revision will have the same output from 'log'.
  (Robert Collins)

* 'merge' accepts --remember option to store parent location, like 'push'
  and 'pull'. (Olaf Conradi)

* bzr status and diff when files given as arguments do not exist
  in the relevant trees.  (Martin Pool, #3619)

* Add '.hg' to the default ignore list.  (Martin Pool)

* 'knit' is now the default disk format. This improves disk performance and
  utilization, increases incremental pull performance, robustness with SFTP
  and allows checkouts over SFTP to perform acceptably.
  The initial Knit code was contributed by Johan Rydberg based on a
  specification by Martin Pool.
  (Robert Collins, Aaron Bentley, Johan Rydberg, Martin Pool).

* New tool to generate all-in-one html version of the manual.  (Alexander
  Belchenko)

* Hitting CTRL-C while doing an SFTP push will no longer cause stale locks
  to be left in the SFTP repository. (Robert Collins, Martin Pool).

* New option 'diff --prefix' to control how files are named in diff
  output, with shortcuts '-p0' and '-p1' corresponding to the options for
  GNU patch.  (Alexander Belchenko, Goffredo Baroncelli, Martin Pool)

* Add --revision option to 'annotate' command.  (Olaf Conradi)

* If bzr shows an unexpected revision-history after pulling (perhaps due
  to a reweave) it can now be corrected by 'bzr reconcile'.
  (Robert Collins)

Changes
*******

* Commit is now verbose by default, and shows changed filenames and the
  new revision number.  (Robert Collins, Martin Pool)

* Unify 'mv', 'move', 'rename'.  (Matthew Fuller, #5379)

* 'bzr -h' shows help.  (Martin Pool, Ian Bicking, #35940)

* Make 'pull' and 'push' remember location on failure using --remember.
  (Olaf Conradi)

* For compatibility, make old format for using weaves inside metadir
  available as 'metaweave' format.  Rename format 'metadir' to 'default'.
  Clean up help for option --format in commands 'init', 'init-repo' and
  'upgrade'.  (Olaf Conradi)

Internals
*********

* The internal storage of history, and logical branch identity have now
  been split into Branch, and Repository. The common locking and file
  management routines are now in bzrlib.lockablefiles.
  (Aaron Bentley, Robert Collins, Martin Pool)

* Transports can now raise DependencyNotPresent if they need a library
  which is not installed, and then another implementation will be
  tried.  (Martin Pool)

* Remove obsolete (and no-op) `decode` parameter to `Transport.get`.
  (Martin Pool)

* Using Tree Transform for merge, revert, tree-building

* WorkingTree.create, Branch.create, ``WorkingTree.create_standalone``,
  Branch.initialize are now deprecated. Please see ``BzrDir.create_*`` for
  replacement API's. (Robert Collins)

* New BzrDir class represents the .bzr control directory and manages
  formatting issues. (Robert Collins)

* New repository.InterRepository class encapsulates Repository to
  Repository actions and allows for clean selection of optimised code
  paths. (Robert Collins)

* ``bzrlib.fetch.fetch`` and ``bzrlib.fetch.greedy_fetch`` are now
  deprecated, please use ``branch.fetch`` or ``repository.fetch``
  depending on your needs. (Robert Collins)

* deprecated methods now have a ``is_deprecated`` flag on them that can
  be checked, if you need to determine whether a given callable is
  deprecated at runtime. (Robert Collins)

* Progress bars are now nested - see
  ``bzrlib.ui.ui_factory.nested_progress_bar``.
  (Robert Collins, Robey Pointer)

* New API call ``get_format_description()`` for each type of format.
  (Olaf Conradi)

* Changed ``branch.set_parent()`` to accept None to remove parent.
  (Olaf Conradi)

* Deprecated BzrError AmbiguousBase.  (Olaf Conradi)

* WorkingTree.branch is now a read only property.  (Robert Collins)

* bzrlib.ui.text.TextUIFactory now accepts a ``bar_type`` parameter which
  can be None or a factory that will create a progress bar. This is
  useful for testing or for overriding the bzrlib.progress heuristic.
  (Robert Collins)

* New API method ``get_physical_lock_status()`` to query locks present on a
  transport.  (Olaf Conradi)

* Repository.reconcile now takes a thorough keyword parameter to allow
  requesting an indepth reconciliation, rather than just a data-loss
  check. (Robert Collins)

* ``bzrlib.ui.ui_factory protocol`` now supports ``get_boolean`` to prompt
  the user for yes/no style input. (Robert Collins)

Testing
*******

* SFTP tests now shortcut the SSH negotiation, reducing test overhead
  for testing SFTP protocol support. (Robey Pointer)

* Branch formats are now tested once per implementation (see ``bzrlib.
  tests.branch_implementations``. This is analagous to the transport
  interface tests, and has been followed up with working tree,
  repository and BzrDir tests. (Robert Collins)

* New test base class TestCaseWithTransport provides a transport aware
  test environment, useful for testing any transport-interface using
  code. The test suite option --transport controls the transport used
  by this class (when its not being used as part of implementation
  contract testing). (Robert Collins)

* Close logging handler on disabling the test log. This will remove the
  handler from the internal list inside python's logging module,
  preventing shutdown from closing it twice.  (Olaf Conradi)

* Move test case for uncommit to blackbox tests.  (Olaf Conradi)

* ``run_bzr`` and ``run_bzr_captured`` now accept a 'stdin="foo"'
  parameter which will provide String("foo") to the command as its stdin.
