bzr 0.8rc2  2006-05-05

  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 weaves than knits.  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.

    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, John 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)

    * 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'.  (#5379, Matthew Fuller)

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

    * 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)

  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)

bzr 0.7 2006-01-09

  CHANGES:

    * .bzrignore is excluded from exports, on the grounds that it's a bzr 

      internal-use file and may not be wanted.  (Jamie Wilkinson)

    * The "bzr directories" command were removed in favor of the new

      --kind option to the "bzr inventory" command.  To list all 

      versioned directories, now use "bzr inventory --kind directory".  

      (Johan Rydberg)

    * Under Windows configuration directory is now %APPDATA%\bazaar\2.0

      by default. (John Arbash Meinel)

    * The parent of Bzr configuration directory can be set by BZR_HOME

      environment variable. Now the path for it is searched in BZR_HOME, then

      in HOME. Under Windows the order is: BZR_HOME, APPDATA (usually

      points to C:\Documents and Settings\User Name\Application Data), HOME.

      (John Arbash Meinel)

    * Plugins with the same name in different directories in the bzr plugin

      path are no longer loaded: only the first successfully loaded one is

      used. (Robert Collins)

    * Use systems' external ssh command to open connections if possible.  

      This gives better integration with user settings such as ProxyCommand.

      (James Henstridge)

    * Permissions on files underneath .bzr/ are inherited from the .bzr 

      directory. So for a shared repository, simply doing 'chmod -R g+w .bzr/'

      will mean that future file will be created with group write permissions.

    * configure.in and config.guess are no longer in the builtin default 

      ignore list.

    * '.sw[nop]' pattern ignored, to ignore vim swap files for nameless

      files.  (John Arbash Meinel, Martin Pool)

  IMPROVEMENTS:

    * "bzr INIT dir" now initializes the specified directory, and creates 

      it if it does not exist.  (John Arbash Meinel)

    * New remerge command (Aaron Bentley)

    * Better zsh completion script.  (Steve Borho)

    * 'bzr diff' now returns 1 when there are changes in the working 

      tree. (Robert Collins)

    * 'bzr push' now exists and can push changes to a remote location. 

      This uses the transport infrastructure, and can store the remote

      location in the ~/.bazaar/branches.conf configuration file.

      (Robert Collins)

    * Test directories are only kept if the test fails and the user requests

      that they be kept.

    * Tweaks to short log printing

    * Added branch nicks, new nick command, printing them in log output. 

      (Aaron Bentley)

    * If $BZR_PDB is set, pop into the debugger when an uncaught exception 

      occurs.  (Martin Pool)

    * Accept 'bzr resolved' (an alias for 'bzr resolve'), as this is

      the same as Subversion.  (Martin Pool)

    * New ftp transport support (on ftplib), for ftp:// and aftp:// 

      URLs.  (Daniel Silverstone)

    * Commit editor temporary files now start with 'bzr_log.', to allow 

      text editors to match the file name and set up appropriate modes or 

      settings.  (Magnus Therning)

    * Improved performance when integrating changes from a remote weave.  

      (Goffredo Baroncelli)

    * Sftp will attempt to cache the connection, so it is more likely that

      a connection will be reused, rather than requiring multiple password

      requests.

    * bzr revno now takes an optional argument indicating the branch whose

      revno should be printed.  (Michael Ellerman)

    * bzr cat defaults to printing the last version of the file.  

      (#3632, Matthieu Moy)

    * New global option 'bzr --lsprof COMMAND' runs bzr under the lsprof 

      profiler.  (Denys Duchier)

    * Faster commits by reading only the headers of affected weave files. 

      (Denys Duchier)

    * 'bzr add' now takes a --dry-run parameter which shows you what would be

      added, but doesn't actually add anything. (Michael Ellerman)

    * 'bzr add' now lists how many files were ignored per glob.  add --verbose

      lists the specific files.  (Aaron Bentley)

    * 'bzr missing' now supports displaying changes in diverged trees and can

      be limited to show what either end of the comparison is missing.

      (Aaron Bently, with a little prompting from Daniel Silverstone)

  BUG FIXES:

    * SFTP can walk up to the root path without index errors. (Robert Collins)

    * Fix bugs in running bzr with 'python -O'.  (Martin Pool)

    * Error when run with -OO

    * Fix bug in reporting http errors that don't have an http error code.

      (Martin Pool)

    * Handle more cases of pipe errors in display commands

    * Change status to 3 for all errors

    * Files that are added and unlinked before committing are completely

      ignored by diff and status

    * Stores with some compressed texts and some uncompressed texts are now

      able to be used. (John A Meinel)

    * Fix for bzr pull failing sometimes under windows

    * Fix for sftp transport under windows when using interactive auth

    * Show files which are both renamed and modified as such in 'bzr 

      status' output.  (#4503, Daniel Silverstone)

    * Make annotate cope better with revisions committed without a valid 

      email address.  (Marien Zwart)

    * Fix representation of tab characters in commit messages.  (Harald 

      Meland)

    * List of plugin directories in BZR_PLUGIN_PATH environment variable is

      now parsed properly under Windows. (Alexander Belchenko)

    * Show number of revisions pushed/pulled/merged. (Robey Pointer)

    * Keep a cached copy of the basis inventory to speed up operations 

      that need to refer to it.  (Johan Rydberg, Martin Pool)

    * Fix bugs in bzr status display of non-ascii characters.  (Martin 

      Pool)

    * Remove Makefile.in from default ignore list.  (#6413, Tollef Fog 

      Heen, Martin Pool)

    * Fix failure in 'bzr added'.  (Nathan McCallum, Martin Pool)

  TESTING:

    * Fix selftest asking for passwords when there are no SFTP keys.  

      (Robey Pointer, Jelmer Vernooij) 

    * Fix selftest run with 'python -O'.  (Martin Pool)

    * Fix HTTP tests under Windows. (John Arbash Meinel)

    * Make tests work even if HOME is not set (Aaron Bentley)

    * Updated build_tree to use fixed line-endings for tests which read 

      the file cotents and compare. Make some tests use this to pass under

      Windows. (John Arbash Meinel)

    * Skip stat and symlink tests under Windows. (Alexander Belchenko)

    * Delay in selftest/testhashcash is now issued under win32 and Cygwin.

      (John Arbash Meinel)

    * Use terminal width to align verbose test output.  (Martin Pool)

    * Blackbox tests are maintained within the bzrlib.tests.blackbox directory.

      If adding a new test script please add that to

      bzrlib.tests.blackbox.__init__. (Robert Collins)

    * Much better error message if one of the test suites can't be 

      imported.  (Martin Pool)

    * Make check now runs the test suite twice - once with the default locale,

      and once with all locales forced to C, to expose bugs. This is not 

      trivially done within python, so for now its only triggered by running

      Make check. Integrators and packagers who wish to check for full 

      platform support should run 'make check' to test the source.

      (Robert Collins)

    * Tests can now run TestSkipped if they can't execute for any reason.

      (Martin Pool) (NB: TestSkipped should only be raised for correctable

      reasons - see the wiki spec ImprovingBzrTestSuite).

    * Test sftp with relative, absolute-in-homedir and absolute-not-in-homedir

      paths for the transport tests. Introduce blackbox remote sftp tests that

      test the same permutations. (Robert Collins, Robey Pointer)

    * Transport implementation tests are now independent of the local file

      system, which allows tests for esoteric transports, and for features

      not available in the local file system. They also repeat for variations

      on the URL scheme that can introduce issues in the transport code,

      see bzrlib.transport.TransportTestProviderAdapter() for this.

      (Robert Collins).

    * TestCase.build_tree uses the transport interface to build trees, pass

      in a transport parameter to give it an existing connection.

      (Robert Collins).

  INTERNALS:

    * WorkingTree.pull has been split across Branch and WorkingTree,

      to allow Branch only pulls. (Robert Collins)

    * commands.display_command now returns the result of the decorated
