bzr 0.9.0  2006-08-11

  SURPRISES:

   * The hard-coded built-in ignore rules have been removed. There are

     now two rulesets which are enforced. A user global one in 

     ~/.bazaar/ignore which will apply to every tree, and the tree

     specific one '.bzrignore'.

     ~/.bazaar/ignore will be created if it does not exist, but with

     a more conservative list than the old default.

     This fixes bugs with default rules being enforced no matter what. 

     The old list of ignore rules from bzr is available by

     running 'bzr ignore --old-default-rules'.

     (Robert Collins, Martin Pool, John Arbash Meinel)

   * 'branches.conf' has been changed to 'locations.conf', since it can apply

     to more locations than just branch locations.

     (Aaron Bentley)

  IMPROVEMENTS:

   * The revision specifier "revno:" is extended to accept the syntax

     revno:N:branch. For example,

     revno:42:http://bazaar-vcs.org/bzr/bzr.dev/ means revision 42 in

     bzr.dev.  (Matthieu Moy)

   * Tests updates to ensure proper URL handling, UNICODE support, and

     proper printing when the user's terminal encoding cannot display 

     the path of a file that has been versioned.

     ``bzr branch`` can take a target URL rather than only a local directory.

     Branch.get_parent()/set_parent() now save a relative path if possible,

     and normalize the parent based on root, allowing access across

     different transports. (John Arbash Meinel, Wouter van Heyst, Martin Pool)

     (Malone #48906, #42699, #40675, #5281, #3980, #36363, #43689,

      #42517, #42514)

   * On Unix, detect terminal width using an ioctl not just $COLUMNS.

     Use terminal width for single-line logs from ``bzr log --line`` and

     pending-merge display.  (Robert Widhopf-Fenk, Gustavo Niemeyer)

     (Malone #3507)

   * On Windows, detect terminal width using GetConsoleScreenBufferInfo.

     (Alexander Belchenko)

   * Speedup improvement for 'date:'-revision search. (Guillaume Pinot).

   * Show the correct number of revisions pushed when pushing a new branch.

     (Robert Collins).

   * 'bzr selftest' now shows a progress bar with the number of tests, and 

     progress made. 'make check' shows tests in -v mode, to be more useful

     for the PQM status window. (Robert Collins).

     When using a progress bar, failed tests are printed out, rather than

     being overwritten by the progress bar until the suite finishes.

     (John Arbash Meinel)

   * 'bzr selftest --benchmark' will run a new benchmarking selftest.

     'bzr selftest --benchmark --lsprof-timed' will use lsprofile to generate

     profile data for the individual profiled calls, allowing for fine

     grained analysis of performance.

     (Robert Collins, Martin Pool).

   * 'bzr commit' shows a progress bar. This is useful for commits over sftp

     where commit can take an appreciable time. (Robert Collins)

   * 'bzr add' is now less verbose in telling you what ignore globs were

     matched by files being ignored. Instead it just tells you how many 

     were ignored (because you might reasonably be expecting none to be

     ignored). 'bzr add -v' is unchanged and will report every ignored

     file. (Robert Collins).

   * ftp now has a test server if medusa is installed. As part of testing,

     ftp support has been improved, including support for supplying a

     non-standard port. (John Arbash Meinel).

   * 'bzr log --line' shows the revision number, and uses only the

     first line of the log message (#5162, Alexander Belchenko;

     Matthieu Moy)

   * 'bzr status' has had the --all option removed. The 'bzr ls' command

     should be used to retrieve all versioned files. (Robert Collins)

   * 'bzr bundle OTHER/BRANCH' will create a bundle which can be sent

     over email, and applied on the other end, while maintaining ancestry.

     This bundle can be applied with either 'bzr merge' or 'bzr pull',

     the same way you would apply another branch.

     (John Arbash Meinel, Aaron Bentley)

   * 'bzr whoami' can now be used to set your identity from the command line,

     for a branch or globally.  (Robey Pointer)

   * 'bzr checkout' now aliased to 'bzr co', and 'bzr annotate' to 'bzr ann'.

     (Michael Ellerman)

   * 'bzr revert DIRECTORY' now reverts the contents of the directory as well.

     (Aaron Bentley)

   * 'bzr get sftp://foo' gives a better error when paramiko is not present.

     Also updates things like 'http+pycurl://' if pycurl is not present.

     (John Arbash Meinel) (Malone #47821, #52204)

   * New env variable BZR_PROGRESS_BAR, sets the default progress bar type.

     Can be set to 'none' or 'dummy' to disable the progress bar, 'dots' or 

     'tty' to create the respective type. (John Arbash Meinel, #42197, #51107)

   * Improve the help text for 'bzr diff' to explain what various options do.

     (John Arbash Meinel, #6391)

   * 'bzr uncommit -r 10' now uncommits revisions 11.. rather than uncommitting

     revision 10. This makes -r10 more in line with what other commands do.

     'bzr uncommit' also now saves the pending merges of the revisions that

     were removed. So it is safe to uncommit after a merge, fix something,

     and commit again. (John Arbash Meinel, #32526, #31426)

   * 'bzr init' now also works on remote locations.

     (Wouter van Heyst, #48904)

   * HTTP support has been updated. When using pycurl we now support 

     connection keep-alive, which reduces dns requests and round trips.

     And for both urllib and pycurl we support multi-range requests, 

     which decreases the number of round-trips. Performance results for

     ``bzr branch http://bazaar-vcs.org/bzr/bzr.dev/`` indicate

     http branching is now 2-3x faster, and ``bzr pull`` in an existing 

     branch is as much as 4x faster.

     (Michael Ellerman, Johan Rydberg, John Arbash Meinel, #46768)

   * Performance improvements for sftp. Branching and pulling are now up to

     2x faster. Utilize paramiko.readv() support for async requests if it

     is available (paramiko > 1.6) (John Arbash Meinel)

  BUG FIXES:

    * Fix shadowed definition of TestLocationConfig that caused some 

      tests not to run.  (#32587, Erik Bågfors, Michael Ellerman, 

      Martin Pool)

    * Fix unnecessary requirement of sign-my-commits that it be run from

      a working directory.  (Martin Pool, Robert Collins)

    * 'bzr push location' will only remember the push location if it succeeds

      in connecting to the remote location. (#49742, John Arbash Meinel)

    * 'bzr revert' no longer toggles the executable bit on win32

      (#45010, John Arbash Meinel)

    * Handle broken pipe under win32 correctly. (John Arbash Meinel)

    * sftp tests now work correctly on win32 if you have a newer paramiko

      (John Arbash Meinel)

    * Cleanup win32 test suite, and general cleanup of places where

      file handles were being held open. (John Arbash Meinel)

    * When specifying filenames for 'diff -r x..y', the name of the file in the

      working directory can be used, even if its name is different in both x

      and y.

    * File-ids containing single- or double-quotes are handled correctly by

      push.  (#52227, Aaron Bentley)

    * Normalize unicode filenames to ensure cross-platform consistency.

      (John Arbash Meinel, #43689)

    * The argument parser can now handle '-' as an argument. Currently

      no code interprets it specially (it is mostly handled as a file named 

      '-'). But plugins, and future operations can use it.

      (John Arbash meinel, #50984)

    * Bundles can properly read binary files with a plain '\r' in them.

      (John Arbash Meinel, #51927)

    * Tuning iter_entries() to be more efficient (John Arbash Meinel, #5444)

    * Lots of win32 fixes (the test suite passes again).

      (John Arbash Meinel, #50155)

    * Handle openbsd returning None for sys.getfilesystemencoding() (#41183) 

    * Support ftp APPE (append) to allow Knits to be used over ftp (#42592)

    * Removals are only committed if they match the filespec (or if there is

      no filespec).  (#46635, Aaron Bentley)

    * smart-add recurses through all supplied directories 

      (John Arbash Meinel, #52578)

    * Make the bundle reader extra lines before and after the bundle text.

      This allows you to parse an email with the bundle inline.

      (John Arbash Meinel, #49182)

    * Change the file id generator to squash a little bit more. Helps when

      working with long filenames on windows. (Also helps for unicode filenames

      not generating hidden files). (John Arbash Meinel, #43801)

    * Restore terminal mode on C-c while reading sftp password.  (#48923, 

      Nicholas Allen, Martin Pool)

    * Timestamps are rounded to 1ms, and revision entries can be recreated

      exactly. (John Arbash Meinel, Jamie Wilkinson, #40693)

    * Branch.base has changed to a URL, but ~/.bazaar/locations.conf should

      use local paths, since it is user visible (John Arbash Meinel, #53653)

    * ``bzr status foo`` when foo was unversioned used to cause a full delta

      to be generated (John Arbash Meinel, #53638)

    * When reading revision properties, an empty value should be considered

      the empty string, not None (John Arbash Meinel, #47782)

    * ``bzr diff --diff-options`` can now handle binary files being changed.

      Also, the output is consistent when --diff-options is not supplied.

      (John Arbash Meinel, #54651, #52930)

    * Use the right suffixes for loading plugins (John Arbash Meinel, #51810)

    * Fix Branch.get_parent() to handle the case when the parent is not 

      accessible (John Arbash Meinel, #52976)

  INTERNALS:

    * Combine the ignore rules into a single regex rather than looping over

      them to reduce the threshold where  N^2 behaviour occurs in operations

      like status. (Jan Hudec, Robert Collins).

    * Appending to bzrlib.DEFAULT_IGNORE is now deprecated. Instead, use

      one of the add functions in bzrlib.ignores. (John Arbash Meinel)

    * 'bzr push' should only push the ancestry of the current revision, not

      all of the history in the repository. This is especially important for

      shared repositories. (John Arbash Meinel)

    * bzrlib.delta.compare_trees now iterates in alphabetically sorted order,

      rather than randomly walking the inventories. (John Arbash Meinel)

    * Doctests are now run in temporary directories which are cleaned up when

      they finish, rather than using special ScratchDir/ScratchBranch objects.

      (Martin Pool)

    * Split ``check`` into separate methods on the branch and on the repository,

      so that it can be specialized in ways that are useful or efficient for

      different formats.  (Martin Pool, Robert Collins)

    * Deprecate Repository.all_revision_ids; most methods don't really need

      the global revision graph but only that part leading up to a particular

      revision.  (Martin Pool, Robert Collins)

    * Add a BzrDirFormat control_formats list which allows for control formats

      that do not use '.bzr' to store their data - i.e. '.svn', '.hg' etc.

      (Robert Collins, Jelmer Vernooij).

    * bzrlib.diff.external_diff can be redirected to any file-like object.

      Uses subprocess instead of spawnvp.

      (#4047, #48914, James Henstridge, John Arbash Meinel)

    * New command line option '--profile-imports', which will install a custom

      importer to log time to import modules and regex compilation time to 

      sys.stderr (John Arbash Meinel)

    * 'EmptyTree' is now deprecated, please use repository.revision_tree(None)

      instead. (Robert Collins)

    * "RevisionTree" is now in bzrlib/revisiontree.py. (Robert Collins)

bzr 0.8.2  2006-05-17

  BUG FIXES:

    * setup.py failed to install launchpad plugin.  (Martin Pool)

bzr 0.8.1  2006-05-16

  BUG FIXES:

    * Fix failure to commit a merge in a checkout.  (Martin Pool, 

      Robert Collins, Erik Bågfors, #43959)

    * Nicer messages from 'commit' in the case of renames, and correct

      messages when a merge has occured. (Robert Collins, Martin Pool)

    * Separate functionality from assert statements as they are skipped in

      optimized mode of python. Add the same check to pending merges.

      (#44443, Olaf Conradi)

  CHANGES:

    * Do not show the None revision in output of bzr ancestry. (Olaf Conradi)

    * Add info on standalone branches without a working tree.

      (#44155, Olaf Conradi)

    * Fix bug in knits when raising InvalidRevisionId. (#44284, Olaf Conradi)

  CHANGES:

    * Make editor invocation comply with Debian Policy. First check

      environment variables VISUAL and EDITOR, then try editor from

      alternatives system. If that all fails, fall back to the pre-defined

      list of editors. (#42904, Olaf Conradi)

  NEW FEATURES:

    * New 'register-branch' command registers a public branch into 

      Launchpad.net, where it can be associated with bugs, etc.

      (Martin Pool, Bjorn Tillenius, Robert Collins)

  INTERNALS:

    * New public api in InventoryEntry - 'describe_change(old, new)' which

      provides a human description of the changes between two old and

      new. (Robert Collins, Martin Pool)

  TESTING:

    * Fix test case for bzr info in upgrading a standalone branch to metadir,

      uses bzrlib api now. (Olaf Conradi)

bzr 0.8  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'.  (#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)

    * 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.
