/brz/remove-bazaar

IN DEVELOPMENT

  IMPROVEMENTS:

    * Support for OS Windows 98. Also .bzr.log on any windows system

      saved in My Documents folder. (Alexander Belchenko)

    * ``bzr mv`` enhanced to support already moved files.

      In the past the mv command would have failed if the source file doesn't

      exist. In this situation ``bzr mv`` would now detect that the file has

      already moved and update the repository accordingly, if the target file

      does exist.

      A new option ``--after`` has been added so that if two files already

      exist, you could notify Bazaar that you have moved a (versioned) file

      and replaced it with another. Thus in this case ``bzr move --after``

      will only update the Bazaar identifier.

      (Steffen Eichenberg, Marius Kruger)

    * ``ls`` now works on treeless branches and remote branches.

      (Aaron Bentley)

    * ``bzr help global-options`` describes the global options.

      (Aaron Bentley)

    * ``bzr pull --overwrite`` will now correctly overwrite checkouts.

      (Robert Collins)

    * Files are now allowed to change kind (e.g. from file to symlink).

      Supported by ``commit``, ``revert`` and ``status``

      (Aaron Bentley)

    * ``inventory`` and ``unknowns`` hidden in favour of ``ls``

      (Aaron Bentley)

    * ``bzr help checkouts`` descibes what checkouts are and some possible

      uses of them. (James Westby, Aaron Bentley)

    * A new ``-d`` option to push, pull and merge overrides the default 

      directory.  (Martin Pool)

    * Branch format 6: smaller, and potentially faster than format 5.  Supports

      "append_history_only" mode, where the log view and revnos do not change,

      except by being added to.  Stores policy settings in

      ".bzr/branch/branch.conf".

    * append_only branches:  Format 6 branches may be configured so that log

      view and revnos are always consistent.  Either create the branch using

      "bzr init --append-revisions-only" or edit the config file as descriped

      in docs/configuration.txt.

    * rebind: Format 6 branches retain the last-used bind location, so if you

      "bzr unbind", you can "bzr bind" to bind to the previously-selected

      bind location.

  INTERNALS:

    * Internally revision ids are now passed around as utf-8 bytestrings,

      rather than treating them as Unicode strings. This has performance

      benefits for Knits, since we no longer need to decode the revision

      id for each line of content, nor for each entry in the index. This

      will also help with the future dirstate format. File-ids should

      receive the same treatment in the future. (John Arbash Meinel)

    * Reserved ids (any revision-id ending in a colon) are rejected by

      versionedfiles, repositories, branches, and working trees

      (Aaron Bentley)

    * Minor performance improvement by not creating a ProgressBar for

      every KnitIndex we create. (about 90ms for a bzr.dev tree)

      (John Arbash Meinel)

    * New easier to use Branch hooks facility. There are five initial hooks,

      all documented in bzrlib.branch.BranchHooks.__init__ - 'set_rh',

      'post_push', 'post_pull', 'post_commit', 'post_uncommit'. These hooks

      fire after the matching operation on a branch has taken place, and were

      originally added for the branchrss plugin. (Robert Collins)

    * New method ``Branch.push()`` which should be used when pushing from a

      branch as it makes performance and policy decisions to match the UI

      level command ``push``. (Robert Collins).

    * New Branch.last_revision_info method, this is being done to allow

      optimization of requests for both the number of revisions and the last

      revision of a branch with smartservers and potentially future branch

      formats. (Wouter van Heyst, Robert Collins)

    * Allow 'import bzrlib.plugins.NAME' to work when the plugin NAME has not

      yet been loaded by load_plugins(). This allows plugins to depend on each

      other for code reuse without requiring users to perform file-renaming

      gymnastics. (Robert Collins)

    * New Repository method 'gather_stats' for statistic data collection.

      This is expected to grow to cover a number of related uses mainly

      related to bzr info. (Robert Collins)

    * Log formatters are now managed with a registry.  log.register_formatter

      continues to work, but callers accessed the FORMATTERS dictionary

      directly will not.

    * ``GPGStrategy.sign()`` will now raise ``BzrBadParameterUnicode`` if

      you pass a Unicode string rather than an 8-bit string. Callers need

      to be updated to encode first. (John Arbash Meinel)

  BUGFIXES:

    * ``bzr annotate`` now uses dotted revnos from the viewpoint of the

      branch, rather than the last changed revision of the file.

      (John Arbash Meinel, #82158)

    * Lock operations no longer hang if they encounter a permission problem.

      (Aaron Bentley)

    * ``bzr push`` can resume a push that was canceled before it finished.

      Also, it can push even if the target directory exists if you supply

      the ``--use-existing-dir`` flag.

      (John Arbash Meinel, #30576, #45504)

    * Fix http proxy authentication when user and an optional

      password appears in the *_proxy vars. (Vincent Ladeuil,

      #83954).

    * ``bzr log branch/file`` works for local treeless branches

      (Aaron Bentley, #84247)

    * Fix problem with UNC paths on Windows 98. (Alexander Belchenko, #84728)

  TESTING:

    * New ``--first`` option to ``bzr selftest`` to run specified tests

      before the rest of the suite.  (Martin Pool)

bzr 0.14  2007-01-23

  IMPROVEMENTS:

    * ``bzr help global-options`` describes the global options. (Aaron Bentley)

  BUG FIXES:

    * Skip documentation generation tests if the tools to do so are not

      available. Fixes running selftest for installled copies of bzr. 

      (John Arbash Meinel, #80330)

    * Fix the code that discovers whether bzr is being run from it's

      working tree to handle the case when it isn't but the directory

      it is in is below a repository. (James Westby, #77306)

bzr 0.14rc1  2007-01-16

  IMPROVEMENTS:

    * New connection: ``bzr+http://`` which supports tunnelling the smart

      protocol over an HTTP connection. If writing is enabled on the bzr

      server, then you can write over the http connection.

      (Andrew Bennetts, John Arbash Meinel)

    * Aliases now support quotation marks, so they can contain whitespace

      (Marius Kruger)

    * PyCurlTransport now use a single curl object. By specifying explicitly

      the 'Range' header, we avoid the need to use two different curl objects

      (and two connections to the same server). (Vincent Ladeuil)

    * ``bzr commit`` does not prompt for a message until it is very likely to

      succeed.  (Aaron Bentley)

    * ``bzr conflicts`` now takes --text to list pathnames of text conflicts

      (Aaron Bentley)

    * Fix ``iter_lines_added_or_present_in_versions`` to use a set instead

      of a list while checking if a revision id was requested. Takes 10s

      off of the ``fileids_affected_by_revision_ids`` time, which is 10s

      of the ``bzr branch`` time. Also improve ``fileids_...`` time by

      filtering lines with a regex rather than multiple ``str.find()``

      calls. (saves another 300ms) (John Arbash Meinel)

    * Policy can be set for each configuration key. This allows keys to be

      inherited properly across configuration entries. For example, this

      should enable you to do::

        [/home/user/project]

        push_location = sftp://host/srv/project/

        push_location:policy = appendpath

      And then a branch like ``/home/user/project/mybranch`` should get an

      automatic push location of ``sftp://host/srv/project/mybranch``.

      (James Henstridge)

    * Added ``bzr status --short`` to make status report svn style flags

      for each file.  For example::

        $ bzr status --short

        A  foo

        A  bar

        D  baz

        ?  wooley

    * 'bzr selftest --clean-output' allows easily clean temporary tests 

      directories without running tests. (Alexander Belchenko)

    * ``bzr help hidden-commands`` lists all hidden commands. (Aaron Bentley)

    * ``bzr merge`` now has an option ``--pull`` to fall back to pull if

      local is fully merged into remote. (Jan Hudec)

    * ``bzr help formats`` describes available directory formats. (Aaron Bentley)

  INTERNALS:

    * A few tweaks directly to ``fileids_affected_by_revision_ids`` to

      help speed up processing, as well allowing to extract unannotated

      lines. Between the two ``fileids_affected_by_revision_ids`` is

      improved by approx 10%. (John Arbash Meinel)

    * Change Revision serialization to only write out millisecond

      resolution. Rather than expecting floating point serialization to

      preserve more resolution than we need. (Henri Weichers, Martin Pool)

    * Test suite ends cleanly on Windows.  (Vincent Ladeuil)

    * When 'encoding_type' attribute of class Command is equal to 'exact', 

      force sys.stdout to be a binary stream on Windows, and therefore

      keep exact line-endings (without LF -> CRLF conversion).

      (Alexander Belchenko)

    * Single-letter short options are no longer globally declared.  (Martin

      Pool)

    * Before using detected user/terminal encoding bzr should check

      that Python has corresponding codec. (Alexander Belchenko)

    * Formats for end-user selection are provided via a FormatRegistry (Aaron Bentley)

  BUG FIXES:

    * ``bzr missing --verbose`` was showing adds/removals in the wrong

      direction. (John Arbash Meinel)

    * ``bzr annotate`` now defaults to showing dotted revnos for merged

      revisions. It cuts them off at a depth of 12 characters, but you can

      supply ``--long`` to see the full number. You can also use

      ``--show-ids`` to display the original revision ids, rather than

      revision numbers and committer names. (John Arbash Meinel, #75637)

    * bzr now supports Win32 UNC path (e.g. \\HOST\path). 

      (Alexander Belchenko, #57869)

    * Win32-specific: output of cat, bundle and diff commands don't mangle

      line-endings (Alexander Belchenko, #55276)

    * Replace broken fnmatch based ignore pattern matching with custom pattern

      matcher.

      (Kent Gibson, Jan Hudec #57637)

    * pycurl and urllib can detect short reads at different places. Update

      the test suite to test more cases. Also detect http error code 416

      which was raised for that specific bug. Also enhance the urllib

      robustness by detecting invalid ranges (and pycurl's one by detecting

      short reads during the initial GET). (Vincent Ladeuil, #73948)

    * The urllib connection sharing interacts badly with urllib2

      proxy setting (the connections didn't go thru the proxy

      anymore). Defining a proper ProxyHandler solves the

      problem.  (Vincent Ladeuil, #74759)

    * Use urlutils to generate relative URLs, not osutils 

      (Aaron Bentley, #76229)

    * ``bzr status`` in a readonly directory should work without giving

      lots of errors. (John Arbash Meinel, #76299)

    * Mention the revisionspec topic for the revision option help.

      (Wouter van Heyst, #31663)

    * Allow plugins import from zip archives.

      (Alexander Belchenko, #68124)

bzr 0.13  2006-12-05

  No changes from 0.13rc1

bzr 0.13rc1  2006-11-27

  IMPROVEMENTS:

    * New command ``bzr remove-tree`` allows the removal of the working

      tree from a branch.

      (Daniel Silverstone)

    * urllib uses shared keep-alive connections, so http 

      operations are substantially faster.

      (Vincent Ladeuil, #53654)

    * ``bzr export`` allows an optional branch parameter, to export a bzr

      tree from some other url. For example:

      ``bzr export bzr.tar.gz http://bazaar-vcs.org/bzr/bzr.dev``

      (Daniel Silverstone)

    * Added ``bzr help topics`` to the bzr help system. This gives a

      location for general information, outside of a specific command.

      This includes updates for ``bzr help revisionspec`` the first topic

      included. (Goffredo Baroncelli, John Arbash Meinel, #42714)

    * WSGI-compatible HTTP smart server.  See ``doc/http_smart_server.txt``.

      (Andrew Bennetts)

    * Knit files will now cache full texts only when the size of the

      deltas is as large as the size of the fulltext. (Or after 200

      deltas, whichever comes first). This has the most benefit on large

      files with small changes, such as the inventory for a large project.

      (eg For a project with 2500 files, and 7500 revisions, it changes

      the size of inventory.knit from 11MB to 5.4MB) (John Arbash Meinel)

  INTERNALS:

    * New -D option given before the command line turns on debugging output

      for particular areas.  -Derror shows tracebacks on all errors.

      (Martin Pool)

    * Clean up ``bzr selftest --benchmark bundle`` to correct an import,

      and remove benchmarks that take longer than 10min to run.

      (John Arbash Meinel)

    * Use ``time.time()`` instead of ``time.clock()`` to decide on

      progress throttling. Because ``time.clock()`` is actually CPU time,

      so over a high-latency connection, too many updates get throttled.

      (John Arbash Meinel)

    * ``MemoryTransport.list_dir()`` would strip the first character for

      files or directories in root directory. (John Arbash Meinel)

    * New ``ChrootTransportDecorator``, accessible via the ``chroot+`` url

      prefix.  It disallows any access to locations above a set URL.  (Andrew

      Bennetts)

  BUG FIXES:

    * Now _KnitIndex properly decode revision ids when loading index data.

      And optimize the knit index parsing code.  (Dmitry Vasiliev, John

      Arbash Meinel)

    * ``bzrlib/bzrdir.py`` was directly referencing ``bzrlib.workingtree``,

      without importing it. This prevented ``bzr upgrade`` from working

      unless a plugin already imported ``bzrlib.workingtree``

      (John Arbash Meinel, #70716)

    * Suppress the traceback on invalid URLs (Vincent Ladeuil, #70803).

    * Give nicer error message when an http server returns a 403

      error code. (Vincent Ladeuil, #57644).

    * When a multi-range http GET request fails, try a single

      range one. If it fails too, forget about ranges. Remember that until 

      the death of the transport and propagates that to the clones.

      (Vincent Ladeuil, #62276, #62029).

    * Handles user/passwords supplied in url from command

      line (for the urllib implementation). Don't request already

      known passwords (Vincent Ladeuil, #42383, #44647, #48527)

    * _KnitIndex.add_versions() dictionary compresses revision ids as they

      are added. This fixes bug where fetching remote revisions records

      them as full references rather than integers. (John Arbash Meinel,

      #64789)

    * ``bzr ignore`` strips trailing slashes in patterns.

      Also ``bzr ignore`` rejects absolute paths. (Kent Gibson, #4559)

    * ``bzr ignore`` takes multiple arguments. (Cheuksan Edward Wang, #29488)

    * mv correctly handles paths that traverse symlinks. 

      (Aaron Bentley, #66964)

    * Give nicer looking error messages when failing to connect over ssh.

      (John Arbash Meinel, #49172)

    * Pushing to a remote branch does not currently update the remote working

      tree. After a remote push, ``bzr status`` and ``bzr diff`` on the remote

      machine now show that the working tree is out of date.

      (Cheuksan Edward Wang #48136)

    * Use patiencediff instead of difflib for determining deltas to insert

      into knits. This avoids the O(N^3) behavior of difflib. Patience

      diff should be O(N^2). (Cheuksan Edward Wang, #65714)

    * Running ``bzr log`` on nonexistent file gives an error instead of the

      entire log history. (Cheuksan Edward Wang #50793)

    * ``bzr cat`` can look up contents of removed or renamed files. If the

      pathname is ambiguous, i.e. the files in the old and new trees have

      different id's, the default is the file in the new tree. The user can

      use "--name-from-revision" to select the file in the old tree.

      (Cheuksan Edward Wang, #30190)

  TESTING:

    * TestingHTTPRequestHandler really handles the Range header

      (previously it was ignoring it and returning the whole file,).

bzr 0.12  2006-10-30

  INTERNALS:

    * Clean up ``bzr selftest --benchmark bundle`` to correct an import,

      and remove benchmarks that take longer than 10min to run.

      (John Arbash Meinel)

bzr 0.12rc1  2006-10-23

  IMPROVEMENTS:

    * ``bzr log`` now shows dotted-decimal revision numbers for all revisions,

      rather than just showing a decimal revision number for revisions on the

      mainline. These revision numbers are not yet accepted as input into bzr

      commands such as log, diff etc. (Robert Collins)

    * revisions can now be specified using dotted-decimal revision numbers.

      For instance, ``bzr diff -r 1.2.1..1.2.3. (Robert Collins)

    * ``bzr help commands`` output is now shorter (Aaron Bentley)

    * ``bzr`` now uses lazy importing to reduce the startup time. This has

      a moderate effect on lots of actions, especially ones that have

      little to do. For example ``bzr rocks`` time is down to 116ms from

      283ms. (John Arbash Meinel)

    * New Registry class to provide name-to-object registry-like support,

      for example for schemes where plugins can register new classes to

      do certain tasks (e.g. log formatters). Also provides lazy registration

      to allow modules to be loaded on request. (John Arbash Meinel, Adeodato

      Simó)

  API INCOMPATABILITY:

    * LogFormatter subclasses show now expect the 'revno' parameter to 

      show() to be a string rather than an int. (Robert Collins)

  INTERNALS:

    * ``TestCase.run_bzr``, ``run_bzr_captured``, and ``run_bzr_subprocess``

      can take a ``working_dir='foo'`` parameter, which will change directory 

      for the command. (John Arbash Meinel)

    * ``bzrlib.lazy_regex.lazy_compile`` can be used to create a proxy

      around a regex, which defers compilation until first use. 

      (John Arbash Meinel)

    * ``TestCase.run_bzr_subprocess`` defaults to supplying the

      ``--no-plugins`` parameter to ensure test reproducability, and avoid

      problems with system-wide installed plugins. (John Arbash Meinel)

    * Unique tree root ids are now supported. Newly created trees still

      use the common root id for compatibility with bzr versions before 0.12.

      (Aaron Bentley)

    * ``WorkingTree.set_root_id(None)`` is now deprecated. Please

      pass in inventory.ROOT_ID if you want the default root id value.

      (Robert Collins, John Arbash Meinel)

    * New method ``WorkingTree.flush()`` which will write the current memory

      inventory out to disk. At the same time, read_working_inventory will

      no longer trash the current tree inventory if it has been modified within

      the current lock, and the tree will now ``flush()`` automatically on

      ``unlock()``. ``WorkingTree.set_root_id()`` has been updated to take

      advantage of this functionality. (Robert Collins, John Arbash Meinel)

    * ``bzrlib.tsort.merge_sorted`` now accepts ``generate_revnos``. This

      parameter will cause it to add another column to its output, which

      contains the dotted-decimal revno for each revision, as a tuple.

      (Robert Collins)

    * ``LogFormatter.show_merge`` is deprecated in favour of

      ``LogFormatter.show_merge_revno``. (Robert Collins)

  BUG FIXES:

    * Avoid circular imports by creating a deprecated function for

      ``bzrlib.tree.RevisionTree``. Callers should have been using

      ``bzrlib.revisontree.RevisionTree`` anyway. (John Arbash Meinel,

      #63360, #66349)

    * Don't use ``socket.MSG_WAITALL`` as it doesn't exist on all

      platforms. (Martin Pool, #66356)

    * Don't require ``Content-Type`` in range responses. Assume they are a

      single range if ``Content-Type`` does not exist.

      (John Arbash Meinel, #62473)

    * bzr branch/pull no longer complain about progress bar cleanup when

      interrupted during fetch.  (Aaron Bentley, #54000)

    * ``WorkingTree.set_parent_trees()`` uses the trees to directly write

      the basis inventory, rather than going through the repository. This

      allows us to have 1 inventory read, and 2 inventory writes when

      committing a new tree. (John Arbash Meinel)

    * When reverting, files that are not locally modified that do not exist

      in the target are deleted, not just unversioned (Aaron Bentley)

    * When trying to acquire a lock, don't fail immediately. Instead, try

      a few times (up to 1 hour) before timing out. Also, report why the

      lock is unavailable (John Arbash Meinel, #43521, #49556)

    * Leave HttpTransportBase daughter classes decides how they

      implement cloning. (Vincent Ladeuil, #61606)

    * diff3 does not indicate conflicts on clean merge. (Aaron Bentley)

    * If a commit fails, the commit message is stored in a file at the root of

      the tree for later commit. (Cheuksan Edward Wang, Stefan Metzmacher,

      #32054)

  TESTING:

    * New test base class TestCaseWithMemoryTransport offers memory-only

      testing facilities: its not suitable for tests that need to mutate disk

      state, but most tests should not need that and should be converted to

      TestCaseWithMemoryTransport. (Robert Collins)

    * ``TestCase.make_branch_and_memory_tree`` now takes a format

      option to set the BzrDir, Repository and Branch formats of the

      created objects. (Robert Collins, John Arbash Meinel)

bzr 0.11  2006-10-02

    * Smart server transport test failures on windows fixed. (Lukáš Lalinský).

bzr 0.11rc2  2006-09-27

  BUG FIXES:

    * Test suite hangs on windows fixed. (Andrew Bennets, Alexander Belchenko).

    * Commit performance regression fixed. (Aaron Bentley, Robert Collins, John

      Arbash Meinel).

bzr 0.11rc1  2006-09-25

  IMPROVEMENTS:

    * Knit files now wait to create their contents until the first data is

      added. The old code used to create an empty .knit and a .kndx with just

      the header. However, this caused a lot of extra round trips over sftp.

      This can change the time for ``bzr push`` to create a new remote branch

      from 160s down to 100s. This also affects ``bzr commit`` performance when

      adding new files, ``bzr commit`` on a new kernel-like tree drops from 50s

      down to 40s (John Arbash Meinel, #44692)

    * When an entire subtree has been deleted, commit will now report that

      just the top of the subtree has been deleted, rather than reporting

      all the individual items. (Robert Collins)

    * Commit performs one less XML parse. (Robert Collins)

    * ``bzr checkout`` now operates on readonly branches as well

      as readwrite branches. This fixes bug #39542. (Robert Collins)

    * ``bzr bind`` no longer synchronises history with the master branch.
