Bazaar Release Notes

Contents

bzr 0.90 2007-08-28

IMPROVEMENTS:

  • Documentation is now organized into multiple directories with a level added for different languages or locales. Added the Mini Tutorial and Quick Start Summary (en) documents from the Wiki, improving the content and readability of the former. Formatted NEWS as Release Notes complete with a Table of Conents, one heading per release. Moved the Developer Guide into the main document catalog and provided a link from the developer document catalog back to the main one. (Ian Clatworthy, Sabin Iacob, Alexander Belchenko)

BUGFIXES:

  • Fix ''bzr info bzr://host/'' and other operations on ''bzr://' URLs with an implicit port. We were incorrectly raising PathNotChild due to inconsistent treatment of the ''_port'' attribute on the Transport object. (John Arbash Meinel, Andrew Bennetts, #133965)

bzr 0.90rc1 2007-08-14

BUGFIXES:

  • bzr init should connect to the remote location one time only. We have been connecting several times because we forget to pass around the Transport object. This modifies BzrDir.create_branch_convenience, so that we can give it the Transport we already have. (John Arbash Meinel, Vincent Ladeuil, #111702)
  • Get rid of sftp connection cache (get rid of the FTP one too). (Vincent Ladeuil, #43731)
  • bzr branch {local|remote} remote don't try to create a working tree anymore. (Vincent Ladeuil, #112173)
  • All identified multiple connections for a single bzr command have been fixed. See bzrlib/tests/commands directory. (Vincent Ladeuil)
  • bzr rm now does not insist on --force to delete files that have been renamed but not otherwise modified. (Marius Kruger, #111664)
  • bzr selftest --bench no longer emits deprecation warnings (Lukáš Lalinský)
  • bzr status now honours FILE parameters for conflict lists (Aaron Bentley, #127606)
  • bzr checkout now honours -r when reconstituting a working tree. It also honours -r 0. (Aaron Bentley, #127708)
  • bzr add * no more fails on Windows if working tree contains non-ascii file names. (Kuno Meyer, #127361)
  • allow easy_install bzr runs without fatal errors. (Alexander Belchenko, #125521)
  • Graph._filter_candidate_lca does not raise KeyError if a candidate is eliminated just before it would normally be examined. (Aaron Bentley)
  • SMTP connection failures produce a nice message, not a traceback. (Aaron Bentley)

IMPROVEMENTS:

  • Don't show "dots" progress indicators when run non-interactively, such as from cron. (Martin Pool)
  • info now formats locations more nicely and lists "submit" and "public" branches (Aaron Bentley)
  • New pack command that will trigger database compression within the repository (Robert Collins)
  • Implement _KnitIndex._load_data in a pyrex extension. The pyrex version is approximately 2-3x faster at parsing a .kndx file. Which yields a measurable improvement for commands which have to read from the repository, such as a 1s => 0.75s improvement in bzr diff when there are changes to be shown. (John Arbash Meinel)
  • Merge is now faster. Depending on the scenario, it can be more than 2x faster. (Aaron Bentley)
  • Give a clearer warning, and allow python setup.py install to succeed even if pyrex is not available. (John Arbash Meinel)
  • DirState._read_dirblocks now has an optional Pyrex implementation. This improves the speed of any command that has to read the entire DirState. (diff, status, etc, improve by about 10%). bisect_dirblocks has also been improved, which helps all _get_entry type calls (whenever we are searching for a particular entry in the in-memory DirState). (John Arbash Meinel)
  • bzr pull and bzr push no longer do a complete walk of the branch revision history for ui display unless -v is supplied. (Robert Collins)
  • bzr log -rA..B output shifted to the left margin if the log only contains merge revisions. (Kent Gibson)
  • The plugins command is now public with improved help. (Ian Clatworthy)
  • New bundle and merge directive formats are faster to generate, and more robust against email mangling. New send command replaces bundle-revisions and merge-directive. (Aaron Bentley)
  • Annotate merge now works when there are local changes. (Aaron Bentley)
  • Commit now only shows the progress in terms of directories instead of entries. (Ian Clatworthy)
  • Fix KnitRepository.get_revision_graph to not request the graph 2 times. This makes get_revision_graph 2x faster. (John Arbash Meinel)
  • Fix VersionedFile.get_graph() to avoid using set.difference_update(other), which has bad scaling when other is large. This improves VF.get_graph([version_id]) for a 12.5k graph from 2.9s down to 200ms. (John Arbash Meinel)
  • The --lsprof-file option now generates output for KCacheGrind if the file starts with callgrind.out. This matches the default file filtering done by KCacheGrind's Open Dialog. (Ian Clatworthy)
  • Fix bzr update to avoid an unnecessary branch.get_master_branch call, which avoids 1 extra connection to the remote server. (Partial fix for #128076, John Arbash Meinel)
  • Log errors from the smart server in the trace file, to make debugging test failures (and live failures!) easier. (Andrew Bennetts)
  • The HTML version of the man page has been superceded by a more comprehensive manual called the Bazaar User Reference. This manual is completed generated from the online help topics. As part of this change, limited reStructuredText is now explicitly supported in help topics and command help with 'unnatural' markup being removed prior to display by the online help or inclusion in the man page. (Ian Clatworthy)
  • HTML documentation now use files extension *.html (Alexander Belchenko)
  • The cache of ignore definitions is now cleared in WorkingTree.unlock() so that changes to .bzrignore aren't missed. (#129694, Daniel Watkins)
  • bzr selftest --strict fails if there are any missing features or expected test failures. (Daniel Watkins, #111914)
  • Link to registration survey added to README. (Ian Clatworthy)
  • Windows standalone installer show link to registration survey when installation finished. (Alexander Belchenko)

LIBRARY API BREAKS:

  • Deprecated dictionary bzrlib.option.SHORT_OPTIONS removed. Options are now required to provide a help string and it must comply with the style guide by being one or more sentences with an initial capital and final period. (Martin Pool)
  • KnitIndex.get_parents now returns tuples. (Robert Collins)
  • Ancient unused Repository.text_store attribute has been removed. (Robert Collins)
  • The bzrlib.pack interface has changed to use tuples of bytestrings rather than just bytestrings, making it easier to represent multiple element names. As this interface was not used by any internal facilities since it was introduced in 0.18 no API compatibility is being preserved. The serialised form of these packs is identical with 0.18 when a single element tuple is in use. (Robert Collins)

INTERNALS:

  • merge now uses iter_changes to calculate changes, which makes room for future performance increases. It is also more consistent with other operations that perform comparisons, and reduces reliance on Tree.inventory. (Aaron Bentley)
  • Refactoring of transport classes connected to a remote server. ConnectedTransport is a new class that serves as a basis for all transports needing to connect to a remote server. transport.split_url have been deprecated, use the static method on the object instead. URL tests have been refactored too. (Vincent Ladeuil)
  • Better connection sharing for ConnectedTransport objects. transport.get_transport() now accepts a 'possible_transports' parameter. If a newly requested transport can share a connection with one of the list, it will. (Vincent Ladeuil)
  • Most functions now accept bzrlib.revision.NULL_REVISION to indicate the null revision, and consider using None for this purpose deprecated. (Aaron Bentley)
  • New index module with abstract index functionality. This will be used during the planned changes in the repository layer. Currently the index layer provides a graph aware immutable index, a builder for the same index type to allow creating them, and finally a composer for such indices to allow the use of many indices in a single query. The index performance is not optimised, however the API is stable to allow development on top of the index. (Robert Collins)
  • bzrlib.dirstate.cmp_by_dirs can be used to compare two paths by their directory sections. This is equivalent to comparing path.split('/'), only without having to split the paths. This has a Pyrex implementation available. (John Arbash Meinel)
  • New transport decorator 'unlistable+' which disables the list_dir functionality for testing.
  • Deprecated change_entry in transform.py. (Ian Clatworthy)
  • RevisionTree.get_weave is now deprecated. Tree.plan_merge is now used for performing annotate-merge. (Aaron Bentley)
  • New EmailMessage class to create email messages. (Adeodato Simó)
  • Unused functions on the private interface KnitIndex have been removed. (Robert Collins)
  • New knit.KnitGraphIndex which provides a KnitIndex layered on top of a index.GraphIndex. (Robert Collins)
  • New knit.KnitVersionedFile.iter_parents method that allows querying the parents of many knit nodes at once, reducing round trips to the underlying index. (Robert Collins)
  • Graph now has an is_ancestor method, various bits use it. (Aaron Bentley)
  • The -Dhpss flag now includes timing information. As well as logging when a new connection is opened. (John Arbash Meinel)
  • bzrlib.pack.ContainerWriter now returns an offset, length tuple to callers when inserting data, allowing generation of readv style access during pack creation, without needing a separate pass across the output pack to gather such details. (Robert Collins)
  • bzrlib.pack.make_readv_reader allows readv based access to pack files that are stored on a transport. (Robert Collins)
  • New Repository.has_same_location method that reports if two repository objects refer to the same repository (although with some risk of false negatives). (Andrew Bennetts)
  • InterTree.compare now passes require_versioned on correctly. (Marius Kruger)
  • New methods on Repository - start_write_group, commit_write_group, abort_write_group and is_in_write_group - which provide a clean hook point for transactional Repositories - ones where all the data for a fetch or commit needs to be made atomically available in one step. This allows the write lock to remain while making a series of data insertions. (e.g. data conversion). (Robert Collins)
  • In bzrlib.knit the internal interface has been altered to use 3-tuples (index, pos, length) rather than two-tuples (pos, length) to describe where data in a knit is, allowing knits to be split into many files. (Robert Collins)
  • bzrlib.knit._KnitData split into cache management and physical access with two access classes - _PackAccess and _KnitAccess defined. The former provides access into a .pack file, and the latter provides the current production repository form of .knit files. (Robert Collins)

TESTING:

  • Remove selftest --clean-output, --numbered-dirs and --keep-output options, which are obsolete now that tests are done within directories in $TMPDIR. (Martin Pool)
  • The SSH_AUTH_SOCK environment variable is now reset to avoid interaction with any running ssh agents. (Jelmer Vernooij, #125955)

bzr 0.18 2007-07-17

BUGFIXES:

  • Fix 'bzr add' crash under Win32 (Kuno Meyer)

bzr 0.18rc1 2007-07-10

BUGFIXES:

  • Do not suppress pipe errors, etc. in non-display commands (Alexander Belchenko, #87178)
  • Display a useful error message when the user requests to annotate a file that is not present in the specified revision. (James Westby, #122656)
  • Commands that use status flags now have a reference to 'help status-flags'. (Daniel Watkins, #113436)
  • Work around python-2.4.1 inhability to correctly parse the authentication header. (Vincent Ladeuil, #121889)
  • Use exact encoding for merge directives. (Adeodato Simó, #120591)
  • Fix tempfile permissions error in smart server tar bundling under Windows. (Martin _, #119330)
  • Fix detection of directory entries in the inventory. (James Westby)
  • Fix handling of http code 400: Bad Request When issuing too many ranges. (Vincent Ladeuil, #115209)
  • Issue a CONNECT request when connecting to an https server via a proxy to enable SSL tunneling. (Vincent Ladeuil, #120678)
  • Fix bzr log -r to support selecting merge revisions, both individually and as part of revision ranges. (Kent Gibson, #4663)
  • Don't leave cruft behind when failing to acquire a lockdir. (Martin Pool, #109169)
  • Don't use the '-f' strace option during tests. (Vincent Ladeuil, #102019).
  • Warn when setting push_location to a value that will be masked by locations.conf. (Aaron Bentley, #122286)
  • Fix commit ordering in corner case (Aaron Bentley, #94975)
  • Make annotate behave in a non-ASCII world (Adeodato Simó).

IMPROVEMENTS:

  • The --lsprof-file option now dumps a text rendering of the profiling information if the filename ends in ".txt". It will also convert the profiling information to a format suitable for KCacheGrind if the output filename ends in ".callgrind". Fixes to the lsprofcalltree conversion process by Jean Paul Calderone and Itamar were also merged. See http://ddaa.net/blog/python/lsprof-calltree. (Ian Clatworthy)

  • info now defaults to non-verbose mode, displaying only paths and abbreviated format info. info -v displays all the information formerly displayed by info. (Aaron Bentley, Adeodato Simó)

  • bzr missing now has better option names --this and --other. (Elliot Murphy)

  • The internal weave-list command has become versionedfile-list, and now lists knits as well as weaves. (Aaron Bentley)

  • Automatic merge base selection uses a faster algorithm that chooses better bases in criss-cross merge situations (Aaron Bentley)

  • Progress reporting in commit has been improved. The various logical stages are now reported on as follows, namely:

    • Collecting changes [Entry x/y] - Stage n/m
    • Saving data locally - Stage n/m
    • Uploading data to master branch - Stage n/m
    • Updating the working tree - Stage n/m
    • Running post commit hooks - Stage n/m

    If there is no master branch, the 3rd stage is omitted and the total number of stages is adjusted accordingly.

    Each hook that is run after commit is listed with a name (as hooks can be slow it is useful feedback). (Ian Clatworthy, Robert Collins)

  • Various operations that are now faster due to avoiding unnecessary topological sorts. (Aaron Bentley)

  • Make merge directives robust against broken bundles. (Aaron Bentley)

  • The lsprof filename note is emitted via trace.note(), not standard output. (Aaron Bentley)

  • bzrlib now exports explicit API compatibility information to assist library users and plugins. See the bzrlib.api module for details. (Robert Collins)

  • Remove unnecessary lock probes when acquiring a lockdir. (Martin Pool)

  • bzr --version now shows the location of the bzr log file, which is especially useful on Windows. (Martin Pool)

  • -D now supports hooks to get debug tracing of hooks (though its currently minimal in nature). (Robert Collins)

  • Long log format reports deltas on merge revisions. (John Arbash Meinel, Kent Gibson)

  • Make initial push over ftp more resilient. (John Arbash Meinel)

  • Print a summary of changes for update just like pull does. (Daniel Watkins, #113990)

  • Add a -Dhpss option to trace smart protocol requests and responses. (Andrew Bennetts)

LIBRARY API BREAKS:

  • Testing cleanups - bzrlib.repository.RepositoryTestProviderAdapter has been moved to bzrlib.tests.repository_implementations; bzrlib.repository.InterRepositoryTestProviderAdapter has been moved to bzrlib.tests.interrepository_implementations; bzrlib.transport.TransportTestProviderAdapter has moved to bzrlib.tests.test_transport_implementations. bzrlib.branch.BranchTestProviderAdapter has moved to bzrlib.tests.branch_implementations. bzrlib.bzrdir.BzrDirTestProviderAdapter has moved to bzrlib.tests.bzrdir_implementations. bzrlib.versionedfile.InterVersionedFileTestProviderAdapter has moved to bzrlib.tests.interversionedfile_implementations. bzrlib.store.revision.RevisionStoreTestProviderAdapter has moved to bzrlib.tests.revisionstore_implementations. bzrlib.workingtree.WorkingTreeTestProviderAdapter has moved to bzrlib.tests.workingtree_implementations. These changes are an API break in the testing infrastructure only. (Robert Collins)
  • Relocate TestCaseWithRepository to be more central. (Robert Collins)
  • bzrlib.add.smart_add_tree will no longer perform glob expansion on win32. Callers of the function should do this and use the new MutableTree.smart_add method instead. (Robert Collins)
  • bzrlib.add.glob_expand_for_win32 is now bzrlib.win32utils.glob_expand. (Robert Collins)
  • bzrlib.add.FastPath is now private and moved to bzrlib.mutabletree._FastPath. (Robert Collins, Martin Pool)
  • LockDir.wait removed. (Martin Pool)
  • The SmartServer hooks API has changed for the server_started and server_stopped hooks. The first parameter is now an iterable of backing URLs rather than a single URL. This is to reflect that many URLs may map to the external URL of the server. E.g. the server interally may have a chrooted URL but also the local file:// URL will be at the same location. (Robert Collins)

INTERNALS:

  • New SMTPConnection class to unify email handling. (Adeodato Simó)
  • Fix documentation of BzrError. (Adeodato Simó)
  • Make BzrBadParameter an internal error. (Adeodato Simó)
  • Remove use of 'assert False' to raise an exception unconditionally. (Martin Pool)
  • Give a cleaner error when failing to decode knit index entry. (Martin Pool)
  • TreeConfig would mistakenly search the top level when asked for options from a section. It now respects the section argument and only searches the specified section. (James Westby)
  • Improve make api-docs output. (John Arbash Meinel)
  • Use os.lstat rather than os.stat for osutils.make_readonly and osutils.make_writeable. This makes the difftools plugin more robust when dangling symlinks are found. (Elliot Murphy)
  • New -Dlock option to log (to ~/.bzr.log) information on when lockdirs are taken or released. (Martin Pool)
  • bzrlib Hooks are now nameable using Hooks.name_hook. This allows a nicer UI when hooks are running as the current hook can be displayed. (Robert Collins)
  • Transport.get has had its interface made more clear for ease of use. Retrieval of a directory must now fail with either 'PathError' at open time, or raise 'ReadError' on a read. (Robert Collins)
  • New method _maybe_expand_globs on the Command class for dealing with unexpanded glob lists - e.g. on the win32 platform. This was moved from bzrlib.add._prepare_file_list. (Robert Collins)
  • bzrlib.add.smart_add and bzrlib.add.smart_add_tree are now deprecated in favour of MutableTree.smart_add. (Robert Collins, Martin Pool)
  • New method external_url on Transport for obtaining the url to hand to external processes. (Robert Collins)
  • Teach windows installers to build pyrex/C extensions. (Alexander Belchenko)

TESTING:

  • Removed the --keep-output option from selftest and clean up test directories as they're used. This reduces the IO load from running the test suite and cuts the time by about half. (Andrew Bennetts, Martin Pool)
  • Add scenarios as a public attribute on the TestAdapter classes to allow modification of the generated scenarios before adaption and easier testing. (Robert Collins)
  • New testing support class TestScenarioApplier which multiplies out a single teste by a list of supplied scenarios. (RobertCollins)
  • Setting repository_to_test_repository on a repository_implementations test will cause it to be called during repository creation, allowing the testing of repository classes which are not based around the Format concept. For example a repository adapter can be tested in this manner, by altering the repository scenarios to include a scenario that sets this attribute during the test parameterisation in bzrlib.tests.repository.repository_implementations. (Robert Collins)
  • Clean up many of the APIs for blackbox testing of Bazaar. The standard interface is now self.run_bzr. The command to run can be passed as either a list of parameters, a string containing the command line, or (deprecated) varargs parameters. (Martin Pool)
  • The base TestCase now isolates tests from -D parameters by clearing debug.debug_flags and restores it afterwards. (Robert Collins)
  • Add a relpath parameter to get_transport methods in test framework to avoid useless cloning. (Vincent Ladeuil, #110448)

bzr 0.17 2007-06-18

BUGFIXES:

  • Fix crash of commit due to wrong lookup of filesystem encoding. (Colin Watson, #120647)
  • Revert logging just to stderr in commit as broke unicode filenames. (Aaron Bentley, Ian Clatworthy, #120930)

bzr 0.17rc1 2007-06-12

NOTES WHEN UPGRADING:

  • The kind() and is_executable() APIs on the WorkingTree interface no longer implicitly (read) locks and unlocks the tree. This might impact some plug-ins and tools using this part of the API. If you find an issue that may be caused by this change, please let us know, particularly the plug-in/tool maintainer. If encountered, the API fix is to surround kind() and is_executable() calls with lock_read() and unlock() like so:

    work_tree.lock_read()
    try:
        kind = work_tree.kind(...)
    finally:
        work_tree.unlock()
    
INTERNALS:
  • Rework of LogFormatter API to provide beginning/end of log hooks and to encapsulate the details of the revision to be logged in a LogRevision object. In long log formats, merge revision ids are only shown when --show-ids is specified, and are labelled "revision-id:", as per mainline revisions, instead of "merged:". (Kent Gibson)
  • New BranchBuilder API which allows the construction of particular histories quickly. Useful for testing and potentially other applications too. (Robert Collins)

IMPROVEMENTS:

  • There are two new help topics, working-trees and repositories that attempt to explain these concepts. (James Westby, John Arbash Meinel, Aaron Bentley)
  • Added bzr log --limit to report a limited number of revisions. (Kent Gibson, #3659)
  • Revert does not try to preserve file contents that were originally produced by reverting to a historical revision. (Aaron Bentley)
  • bzr log --short now includes [merge] for revisions which have more than one parent. This is a small improvement to help understanding what changes have occurred (John Arbash Meinel, #83887)
  • TreeTransform avoids many renames when contructing large trees, improving speed. 3.25x speedups have been observed for construction of kernel-sized-trees, and checkouts are 1.28x faster. (Aaron Bentley)
  • Commit on large trees is now faster. In my environment, a commit of a small change to the Mozilla tree (55k files) has dropped from 66 seconds to 32 seconds. For a small tree of 600 files, commit of a small change is 33% faster. (Ian Clatworthy)
  • New --create-prefix option to bzr init, like for push. (Daniel Watkins, #56322)

BUGFIXES:

  • bzr push should only connect to the remote location one time. We have been connecting 3 times because we forget to pass around the Transport object. This adds BzrDir.clone_on_transport(), so that we can pass in the Transport that we already have. (John Arbash Meinel, #75721)
  • DirState.set_state_from_inventory() needs to properly order based on split paths, not just string paths. (John Arbash Meinel, #115947)
  • Let TestUIFactoy encode the password prompt with its own stdout. (Vincent Ladeuil, #110204)
  • pycurl should take use the range header that takes the range hint into account. (Vincent Ladeuil, #112719)
  • WorkingTree4.get_file_sha1 no longer raises an exception when invoked on a missing file. (Aaron Bentley, #118186)
  • WorkingTree.remove works correctly with tree references, and when pwd is not the tree root. (Aaron Bentley)
  • Merge no longer fails when a file is renamed in one tree and deleted in the other. (Aaron Bentley, #110279)
  • revision-info now accepts dotted revnos, doesn't require a tree, and defaults to the last revision (Matthew Fuller, #90048)
  • Tests no longer fail when BZR_REMOTE_PATH is set in the environment. (Daniel Watkins, #111958)
  • bzr branch -r revid:foo can be used to branch any revision in your repository. (Previously Branch6 only supported revisions in your mainline). (John Arbash Meinel, #115343)

bzr 0.16 2007-05-07

BUGFIXES:

  • Handle when you have 2 directories with similar names, but one has a hyphen. ('abc' versus 'abc-2'). The WT4._iter_changes iterator was using direct comparison and 'abc/a' sorts after 'abc-2', but ('abc', 'a') sorts before ('abc-2',). (John Arbash Meinel, #111227)
  • Handle when someone renames a file on disk without telling bzr. Previously we would report the first file as missing, but not show the new unknown file. (John Arbash Meinel, #111288)
  • Avoid error when running hooks after pulling into or pushing from a branch bound to a smartserver branch. (Martin Pool, #111968)

IMPROVEMENTS:

  • Move developer documentation to doc/developers/. This reduces clutter in the root of the source tree and allows HACKING to be split into multiple files. (Robert Collins, Alexander Belchenko)
  • Clean up the WorkingTree4._iter_changes() internal loops as well as DirState.update_entry(). This optimizes the core logic for bzr diff and bzr status significantly improving the speed of both. (John Arbash Meinel)

bzr 0.16rc2 2007-04-30

BUGFIXES:

  • Handle the case when you delete a file, and then rename another file on top of it. Also handle the case of bzr rm --keep foo. bzr status should show the removed file and an unknown file in its place. (John Arbash Meinel, #109993)
  • Bundles properly read and write revision properties that have an empty value. And when the value is not ASCII. (John Arbash Meinel, #109613)
  • Fix the bzr commit message to be in text mode. (Alexander Belchenko, #110901)
  • Also handle when you rename a file and create a file where it used to be. (John Arbash Meinel, #110256)
  • WorkingTree4._iter_changes should not descend into unversioned directories. (John Arbash Meinel, #110399)

bzr 0.16rc1 2007-04-26

NOTES WHEN UPGRADING:

  • bzr remove and bzr rm will now remove the working file, if it could be recovered again. This has been done for consistency with svn and the unix rm command. The old remove behaviour has been retained in the new option bzr remove --keep, which will just stop versioning the file, but not delete it. bzr remove --force have been added which will always delete the files. bzr remove is also more verbose. (Marius Kruger, #82602)

IMPROVEMENTS:

  • Merge directives can now be supplied as input to merge and pull, like bundles can. (Aaron Bentley)
  • Sending the SIGQUIT signal to bzr, which can be done on Unix by pressing Control-Backslash, drops bzr into a debugger. Type 'c' to continue. This can be disabled by setting the environment variable BZR_SIGQUIT_PDB=0. (Martin Pool)
  • selftest now supports --list-only to list tests instead of running them. (Ian Clatworthy)
  • selftest now supports --exclude PATTERN (or -x PATTERN) to exclude tests with names that match that regular expression. (Ian Clatworthy, #102679)
  • selftest now supports --randomize SEED to run tests in a random order. SEED is typically the value 'now' meaning 'use the current time'. (Ian Clatworthy, #102686)
  • New option --fixes to commit, which stores bug fixing annotations as revision properties. Built-in support for Launchpad, Debian, Trac and Bugzilla bug trackers. (Jonathan Lange, James Henstridge, Robert Collins)
  • New API, bzrlib.bugtracker.tracker_registry, for adding support for other bug trackers to fixes. (Jonathan Lange, James Henstridge, Robert Collins)
  • selftest has new short options -f and -1. (Martin Pool)
  • bzrlib.tsort.MergeSorter optimizations. Change the inner loop into using local variables instead of going through self._var. Improves the time to merge_sort a 10k revision graph by approximately 40% (~700->400ms). (John Arbash Meinel)
  • make docs now creates a man page at man1/bzr.1 fixing bug 107388. (Robert Collins)
  • bzr help now provides cross references to other help topics using the _see_also facility on command classes. Likewise the bzr_man documentation, and the bzr.1 man page also include this information. (Robert Collins)
  • Tags are now included in logs, that use the long log formatter. (Erik Bågfors, Alexander Belchenko)
  • bzr help provides a clearer message when a help topic cannot be found. (Robert Collins, #107656)
  • bzr help now accepts optional prefixes for command help. The help for all commands can now be found at bzr help commands/COMMANDNAME as well as bzr help COMMANDNAME (which only works for commands where the name is not the same as a more general help topic). (Robert Collins)
  • bzr help PLUGINNAME will now return the module docstring from the plugin PLUGINNAME. (Robert Collins, #50408)
  • New help topic urlspec which lists the availables transports. (Goffredo Baroncelli)
  • doc/server.txt updated to document the default bzr:// port and also update the blurb about the hpss' current status. (Robert Collins, #107125).
  • bzr serve now listens on interface 0.0.0.0 by default, making it serve out to the local LAN (and anyone in the world that can reach the machine running bzr serve. (Robert Collins, #98918)
  • A new smart server protocol version has been added. It prefixes requests and responses with an explicit version identifier so that future protocol revisions can be dealt with gracefully. (Andrew Bennetts, Robert Collins)
  • The bzr protocol version 2 indicates success or failure in every response without depending on particular commands encoding that consistently, allowing future client refactorings to be much more robust about error handling. (Robert Collins, Martin Pool, Andrew Bennetts)
  • The smart protocol over HTTP client has been changed to always post to the same .bzr/smart URL under the original location when it can. This allows HTTP servers to only have to pass URLs ending in .bzr/smart to the smart server handler, and not arbitrary .bzr/*/smart URLs. (Andrew Bennetts)
  • digest authentication is now supported for proxies and HTTP by the urllib based http implementation. Tested against Apache 2.0.55 and Squid 2.6.5. Basic and digest authentication are handled coherently for HTTP and proxy: if the user is provided in the url (bzr command line for HTTP, proxy environment variables for proxies), the password is prompted for (only once). If the password is provided, it is taken into account. Once the first authentication is successful, all further authentication roundtrips are avoided by preventively setting the right authentication header(s). (Vincent Ladeuil).

INTERNALS:

  • bzrlib API compatability with 0.8 has been dropped, cleaning up some code paths. (Robert Collins)
  • Change the format of chroot urls so that they can be safely manipulated by generic url utilities without causing the resulting urls to have escaped the chroot. A side effect of this is that creating a chroot requires an explicit action using a ChrootServer. (Robert Collins, Andrew Bennetts)
  • Deprecate Branch.get_root_id() because branches don't have root ids, rather than fixing bug #96847. (Aaron Bentley)
  • WorkingTree.apply_inventory_delta provides a better alternative to WorkingTree._write_inventory. (Aaron Bentley)
  • Convenience method TestCase.expectFailure ensures that known failures do not silently pass. (Aaron Bentley)
  • Transport.local_abspath now raises NotLocalUrl rather than TransportNotPossible. (Martin Pool, Ian Clatworthy)
  • New SmartServer hooks facility. There are two initial hooks documented in bzrlib.transport.smart.SmartServerHooks. The two initial hooks allow plugins to execute code upon server startup and shutdown. (Robert Collins).
  • SmartServer in standalone mode will now close its listening socket when it stops, rather than waiting for garbage collection. This primarily fixes test suite hangs when a test tries to connect to a shutdown server. It may also help improve behaviour when dealing with a server running on a specific port (rather than dynamically assigned ports). (Robert Collins)
  • Move most SmartServer code into a new package, bzrlib/smart. bzrlib/transport/remote.py contains just the Transport classes that used to be in bzrlib/transport/smart.py. (Andrew Bennetts)
  • urllib http implementation avoid roundtrips associated with 401 (and 407) errors once the authentication succeeds. (Vincent Ladeuil).
  • urlib http now supports querying the user for a proxy password if needed. Realm is shown in the prompt for both HTTP and proxy authentication when the user is required to type a password. (Vincent Ladeuil).
  • Renamed SmartTransport (and subclasses like SmartTCPTransport) to RemoteTransport (and subclasses to RemoteTCPTransport, etc). This is more consistent with its new home in bzrlib/transport/remote.py, and because it's not really a "smart" transport, just one that does file operations via remote procedure calls. (Andrew Bennetts)
  • The lock_write method of LockableFiles, Repository and Branch now accept a token keyword argument, so that separate instances of those objects can share a lock if it has the right token. (Andrew Bennetts, Robert Collins)
  • New method get_branch_reference on BzrDir allows the detection of branch references - which the smart server component needs.
  • The Repository API make_working_trees is now permitted to return False when set_make_working_trees is not implemented - previously an unimplemented set_make_working_trees implied the result True from make_working_trees. This has been changed to accomodate the smart server, where it does not make sense (at this point) to ever make working trees by default. (Robert Collins)
  • Command objects can now declare related help topics by having _see_also set to a list of related topic. (Robert Collins)
  • bzrlib.help now delegates to the Command class for Command specific help. (Robert Collins)
  • New class TransportListRegistry, derived from the Registry class, which simplifies tracking the available Transports. (Goffredo Baroncelli)
  • New function Branch.get_revision_id_to_revno_map which will return a dictionary mapping revision ids to dotted revnos. Since dotted revnos are defined in the context of the branch tip, it makes sense to generate them from a Branch object. (John Arbash Meinel)
  • Fix the 'Unprintable error' message display to use the repr of the exception that prevented printing the error because the str value for it is often not useful in debugging (e.g. KeyError('foo') has a str() of 'foo' but a repr of 'KeyError('foo')' which is much more useful. (Robert Collins)
  • urlutils.normalize_url now unescapes unreserved characters, such as "~". (Andrew Bennetts)

BUGFIXES:

  • Don't fail bundle selftest if email has 'two' embedded. (Ian Clatworthy, #98510)
  • Remove --verbose from bzr bundle. It didn't work anyway. (Robert Widhopf-Fenk, #98591)
  • Remove --basis from the checkout/branch commands - it didn't work properly and is no longer beneficial. (Robert Collins, #53675, #43486)
  • Don't produce encoding error when adding duplicate files. (Aaron Bentley)
  • Fix bzr log <file> so it only logs the revisions that changed the file, and does it faster. (Kent Gibson, John Arbash Meinel, #51980, #69477)
  • Fix InterDirstateTre._iter_changes to handle when we come across an empty versioned directory, which now has files in it. (John Arbash Meinel, #104257)
  • Teach common_ancestor to shortcut when the tip of one branch is inside the ancestry of the other. Saves a lot of graph processing (with an ancestry of 16k revisions, bzr merge ../already-merged changes from 2m10s to 13s). (John Arbash Meinel, #103757)
  • Fix show_diff_trees to handle the case when a file is modified, and the containing directory is renamed. (The file path is different in this versus base, but it isn't marked as a rename). (John Arbash Meinel, #103870)
  • FTP now works even when the FTP server does not support atomic rename. (Aaron Bentley, #89436)
  • Correct handling in bundles and merge directives of timezones with that are not an integer number of hours offset from UTC. Always represent the epoch time in UTC to avoid problems with formatting earlier times on win32. (Martin Pool, Alexander Belchenko, John Arbash Meinel)
  • Typo in the help for register-branch fixed. (Robert Collins, #96770)
  • "dirstate" and "dirstate-tags" formats now produce branches compatible with old versions of bzr. (Aaron Bentley, #107168))
  • Handle moving a directory when children have been added, removed, and renamed. (John Arbash Meinel, #105479)
  • Don't preventively use basic authentication for proxy before receiving a 407 error. Otherwise people willing to use other authentication schemes may expose their password in the clear (or nearly). This add one roundtrip in case basic authentication should be used, but plug the security hole. (Vincent Ladeuil)
  • Handle http and proxy digest authentication. (Vincent Ladeuil, #94034).

TESTING:

  • Added bzrlib.strace.strace which will strace a single callable and return a StraceResult object which contains just the syscalls involved in running it. (Robert Collins)
  • New test method reduceLockdirTimeout to drop the default (ui-centric) default time down to one suitable for tests. (Andrew Bennetts)
  • Add new vfs_transport_factory attribute on tests which provides the common vfs backing for both the readonly and readwrite transports. This allows the RemoteObject tests to back onto local disk or memory, and use the existing transport_server attribute all tests know about to be the smart server transport. This in turn allows tests to differentiate between 'transport to access the branch', and 'transport which is a VFS' - which matters in Remote* tests. (Robert Collins, Andrew Bennetts)
  • The make_branch_and_tree method for tests will now create a lightweight checkout for the tree if the vfs_transport_factory is not a LocalURLServer. (Robert Collins, Andrew Bennetts)
  • Branch implementation tests have been audited to ensure that all urls passed to Branch APIs use proper urls, except when local-disk paths are intended. This is so that tests correctly access the test transport which is often not equivalent to local disk in Remote* tests. As part of this many tests were adjusted to remove dependencies on local disk access. (Robert Collins, Andrew Bennetts)
  • Mark bzrlib.tests and bzrlib.tests.TestUtil as providing assertFOO helper functions by adding a __unittest global attribute. (Robert Collins, Andrew Bennetts, Martin Pool, Jonathan Lange)
  • Refactored proxy and authentication handling to simplify the implementation of new auth schemes for both http and proxy. (Vincent Ladeuil)

bzr 0.15 2007-04-01

BUGFIXES:

  • Handle incompatible repositories as a user issue when fetching. (Aaron Bentley)
  • Don't give a recommendation to upgrade when branching or checking out a branch that contains an old-format working tree. (Martin Pool)

bzr 0.15rc3 2007-03-26

CHANGES:

  • A warning is now displayed when opening working trees in older formats, to encourage people to upgrade to WorkingTreeFormat4. (Martin Pool)

IMPROVEMENTS:

  • HTTP redirections are now taken into account when a branch (or a bundle) is accessed for the first time. A message is issued at each redirection to inform the user. In the past, http redirections were silently followed for each request which significantly degraded the performances. The http redirections are not followed anymore by default, instead a RedirectRequested exception is raised. For bzrlib users needing to follow http redirections anyway, bzrlib.transport.do_catching_redirections provide an easy transition path. (vila)

INTERNALS:

  • Added ReadLock.temporary_write_lock() to allow upgrading an OS read lock to an OS write lock. Linux can do this without unlocking, Win32 needs to unlock in between. (John Arbash Meinel)
  • New parameter recommend_upgrade to BzrDir.open_workingtree to silence (when false) warnings about opening old formats. (Martin Pool)
  • Fix minor performance regression with bzr-0.15 on pre-dirstate trees. (We were reading the working inventory too many times). (John Arbash Meinel)
  • Remove Branch.get_transaction() in favour of a simple cache of revision_history. Branch subclasses should override _gen_revision_history rather than revision_history to make use of this cache, and call _clear_revision_history_cache and _cache_revision_history at appropriate times. (Andrew Bennetts)

BUGFIXES:

  • Take smtp_server from user config into account. (vila, #92195)
  • Restore Unicode filename handling for versioned and unversioned files. (John Arbash Meinel, #92608)
  • Don't fail during bzr commit if a file is marked removed, and the containing directory is auto-removed. (John Arbash Meinel, #93681)
  • bzr status FILENAME failed on Windows because of an uncommon errno. (ERROR_DIRECTORY == 267 != ENOTDIR). (Wouter van Heyst, John Arbash Meinel, #90819)
  • bzr checkout source should create a local branch in the same format as source. (John Arbash Meinel, #93854)
  • bzr commit with a kind change was failing to update the last-changed-revision for directories. The InventoryDirectory._unchanged only looked at the parent_id and name, ignoring the fact that the kind could have changed, too. (John Arbash Meinel, #90111)
  • bzr mv dir/subdir other was incorrectly updating files inside the directory. So that there was a chance it would break commit, etc. (John Arbash Meinel, #94037)
  • Correctly handles mutiple permanent http redirections. (vila, #88780)

bzr 0.15rc2 2007-03-14

NOTES WHEN UPGRADING:

  • Release 0.15rc2 of bzr changes the bzr init-repo command to default to --trees instead of --no-trees. Existing shared repositories are not affected.

IMPROVEMENTS:

  • New merge-directive command to generate machine- and human-readable merge requests. (Aaron Bentley)
  • New submit: revision specifier makes it easy to diff against the common ancestor with the submit location (Aaron Bentley)
  • Added support for Putty's SSH implementation. (Dmitry Vasiliev)
  • Added bzr status --versioned to report only versioned files, not unknowns. (Kent Gibson)
  • Merge now autodetects the correct line-ending style for its conflict markers. (Aaron Bentley)

INTERNALS:

  • Refactored SSH vendor registration into SSHVendorManager class. (Dmitry Vasiliev)

BUGFIXES:

  • New --numbered-dirs option to bzr selftest to use numbered dirs for TestCaseInTempDir. This is default behavior on Windows. Anyone can force named dirs on Windows with --no-numbered-dirs. (Alexander Belchenko)
  • Fix RevisionSpec_revid to handle the Unicode strings passed in from the command line. (Marien Zwart, #90501)
  • Fix TreeTransform._iter_changes when both the source and destination are missing. (Aaron Bentley, #88842)
  • Fix commit of merges with symlinks in dirstate trees. (Marien Zwart)
  • Switch the bzr init-repo default from --no-trees to --trees. (Wouter van Heyst, #53483)

bzr 0.15rc1 2007-03-07

SURPRISES:

  • The default disk format has changed. Please run 'bzr upgrade' in your working trees to upgrade. This new default is compatible for network operations, but not for local operations. That is, if you have two versions of bzr installed locally, after upgrading you can only use the bzr 0.15 version. This new default does not enable tags or nested-trees as they are incompatible with bzr versions before 0.15 over the network.
  • For users of bzrlib: Two major changes have been made to the working tree api in bzrlib. The first is that many methods and attributes, including the inventory attribute, are no longer valid for use until one of lock_read/lock_write/lock_tree_write has been called, and become invalid again after unlock is called. This has been done to improve performance and correctness as part of the dirstate development. (Robert Collins, John A Meinel, Martin Pool, and others).
  • For users of bzrlib: The attribute 'tree.inventory' should be considered readonly. Previously it was possible to directly alter this attribute, or its contents, and have the tree notice this. This has been made unsupported - it may work in some tree formats, but in the newer dirstate format such actions will have no effect and will be ignored, or even cause assertions. All operations possible can still be carried out by a combination of the tree API, and the bzrlib.transform API. (Robert Collins, John A Meinel, Martin Pool, and others).

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.
  • Builtin tags support, created and deleted by the tag command and stored in the branch. Tags can be accessed with the revisionspec -rtag:, and listed with bzr tags. Tags are not versioned at present. Tags require a network incompatible upgrade. To perform this upgrade, run bzr upgrade --dirstate-tags in your branch and repositories. (Martin Pool)
  • The bzr:// transport now has a well-known port number, 4155, which it will use by default. (Andrew Bennetts, Martin Pool)
  • Bazaar now looks for user-installed plugins before looking for site-wide plugins. (Jonathan Lange)
  • bzr resolve now detects and marks resolved text conflicts. (Aaron Bentley)

INTERNALS:

  • Internally revision ids and file 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. (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).
  • Add a new method Tree.revision_tree which allows access to cached trees for arbitrary revisions. This allows the in development dirstate tree format to provide access to the callers to cached copies of inventory data which are cheaper to access than inventories from the repository. (Robert Collins, Martin Pool)
  • 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 accessing the FORMATTERS dictionary directly will not.
  • Allow a start message to be passed to the edit_commit_message function. This will be placed in the message offered to the user for editing above the separator. It allows a template commit message to be used more easily. (James Westby)
  • 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)
  • Branch.push, pull, merge now return Result objects with information about what happened, rather than a scattering of various methods. These are also passed to the post hooks. (Martin Pool)
  • File formats and architecture is in place for managing a forest of trees in bzr, and splitting up existing trees into smaller subtrees, and finally joining trees to make a larger tree. This is the first iteration of this support, and the user-facing aspects still require substantial work. If you wish to experiment with it, use bzr upgrade --dirstate-with-subtree in your working trees and repositories. You can use the hidden commands split and join and to create and manipulate nested trees, but please consider using the nested-trees branch, which contains substantial UI improvements, instead. http://code.aaronbentley.com/bzr/bzrrepo/nested-trees/ (Aaron Bentley, Martin Pool, Robert Collins).

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)
  • Searching location of CA bundle for PyCurl in env variable (CURL_CA_BUNDLE), and on win32 along the PATH. (Alexander Belchenko, #82086)
  • bzr init works with unicode argument LOCATION. (Alexander Belchenko, #85599)
  • Raise DependencyNotPresent if pycurl do not support https. (Vincent Ladeuil, #85305)
  • Invalid proxy env variables should not cause a traceback. (Vincent Ladeuil, #87765)
  • Ignore patterns normalised to use '/' path separator. (Kent Gibson, #86451)
  • bzr rocks. It sure does! Fix case. (Vincent Ladeuil, #78026)
  • Fix bzrtools shelve command for removed lines beginning with "--" (Johan Dahlberg, #75577)

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 method get_branch_reference on 'BzrDir' allows the detection of branch references - which the smart server component needs.
  • 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. Binding should be followed by an update or push to synchronise the two branches. This is closely related to the fix for bug #39542. (Robert Collins)
  • bzrlib.lazy_import.lazy_import function to create on-demand objects. This allows all imports to stay at the global scope, but modules will not actually be imported if they are not used. (John Arbash Meinel)
  • Support bzr:// and bzr+ssh:// urls to work with the new RPC-based transport which will be used with the upcoming high-performance smart server. The new command bzr serve will invoke bzr in server mode, which processes these requests. (Andrew Bennetts, Robert Collins, Martin Pool)
  • New command bzr version-info which can be used to get a summary of the current state of the tree. This is especially useful as part of a build commands. See doc/version_info.txt for more information (John Arbash Meinel)

BUG FIXES:

  • 'bzr inventory [FILE...]' allows restricting the file list to a specific set of files. (John Arbash Meinel, #3631)
  • Don't abort when annotating empty files (John Arbash Meinel, #56814)
  • Add Stanza.to_unicode() which can be passed to another Stanza when nesting stanzas. Also, add read_stanza_unicode to handle when reading a nested Stanza. (John Arbash Meinel)
  • Transform._set_mode() needs to stat the right file. (John Arbash Meinel, #56549)
  • Raise WeaveFormatError rather than StopIteration when trying to read an empty Weave file. (John Arbash Meinel, #46871)
  • Don't access e.code for generic URLErrors, only HTTPErrors have .code. (Vincent Ladeuil, #59835)
  • Handle boundary="" lines properly to allow access through a Squid proxy. (John Arbash Meinel, #57723)
  • revert now removes newly-added directories (Aaron Bentley, #54172)
  • bzr upgrade sftp:// shouldn't fail to upgrade v6 branches if there isn't a working tree. (David Allouche, #40679)
  • Give nicer error messages when a user supplies an invalid --revision parameter. (John Arbash Meinel, #55420)
  • Handle when LANG is not recognized by python. Emit a warning, but just revert to using 'ascii'. (John Arbash Meinel, #35392)
  • Don't use preexec_fn on win32, as it is not supported by subprocess. (John Arbash Meinel)
  • Skip specific tests when the dependencies aren't met. This includes some setup.py tests when python-dev is not available, and some tests that depend on paramiko. (John Arbash Meinel, Mattheiu Moy)
  • Fallback to Paramiko properly, if no ssh executable exists on the system. (Andrew Bennetts, John Arbash Meinel)
  • Branch.bind(other_branch) no longer takes a write lock on the other branch, and will not push or pull between the two branches. API users will need to perform a push or pull or update operation if they require branch synchronisation to take place. (Robert Collins, #47344)
  • When creating a tarball or zipfile export, export unicode names as utf-8 paths. This may not work perfectly on all platforms, but has the best chance of working in the common case. (John Arbash Meinel, #56816)
  • When committing, only files that exist in working tree or basis tree may be specified (Aaron Bentley, #50793)

PORTABILITY:

  • Fixes to run on Python 2.5 (Brian M. Carlson, Martin Pool, Marien Zwart)

INTERNALS:

  • TestCaseInTempDir now creates a separate directory for HOME, rather than having HOME set to the same location as the working directory. (John Arbash Meinel)
  • run_bzr_subprocess() can take an optional env_changes={} parameter, which will update os.environ inside the spawned child. It also can take a universal_newlines=True, which helps when checking the output of the command. (John Arbash Meinel)
  • Refactor SFTP vendors to allow easier re-use when ssh is used. (Andrew Bennetts)
  • Transport.list_dir() and Transport.iter_files_recursive() should always return urlescaped paths. This is now tested (there were bugs in a few of the transports) (Andrew Bennetts, David Allouche, John Arbash Meinel)
  • New utility function symbol_versioning.deprecation_string. Returns the formatted string for a callable, deprecation format pair. (Robert Collins)
  • New TestCase helper applyDeprecated. This allows you to call a callable which is deprecated without it spewing to the screen, just by supplying the deprecation format string issued for it. (Robert Collins)
  • Transport.append and Transport.put have been deprecated in favor of .append_bytes, .append_file, .put_bytes, and .put_file. This removes the ambiguity in what type of object the functions take. Transport.non_atomic_put_{bytes,file} has also been added. Which works similarly to Transport.append() except for SFTP, it doesn't have a round trip when opening the file. Also, it provides functionality for creating a parent directory when trying to create a file, rather than raise NoSuchFile and forcing the caller to repeat their request. (John Arbash Meinel)
  • WorkingTree has a new api unversion which allow the unversioning of entries by their file id. (Robert Collins)
  • WorkingTree.pending_merges is deprecated. Please use the get_parent_ids (introduced in 0.10) method instead. (Robert Collins)
  • WorkingTree has a new lock_tree_write method which locks the branch for read rather than write. This is appropriate for actions which only need the branch data for reference rather than mutation. A new decorator needs_tree_write_lock is provided in the workingtree module. Like the needs_read_lock and needs_write_lock decorators this allows static declaration of the locking requirements of a function to ensure that a lock is taken out for casual scripts. (Robert Collins, #54107)
  • All WorkingTree methods which write to the tree, but not to the branch have been converted to use needs_tree_write_lock rather than needs_write_lock. Also converted is the revert, conflicts and tree transform modules. This provides a modest performance improvement on metadir style trees, due to the reduce lock-acquisition, and a more significant performance improvement on lightweight checkouts from remote branches, where trivial operations used to pay a significant penalty. It also provides the basis for allowing readonly checkouts. (Robert Collins)
  • Special case importing the standard library 'copy' module. This shaves off 40ms of startup time, while retaining compatibility. See: bzrlib/inspect_for_copy.py for more details. (John Arbash Meinel)
  • WorkingTree has a new parent class MutableTree which represents the specialisations of Tree which are able to be altered. (Robert Collins)
  • New methods mkdir and put_file_bytes_non_atomic on MutableTree that mutate the tree and its contents. (Robert Collins)
  • Transport behaviour at the root of the URL is now defined and tested. (Andrew Bennetts, Robert Collins)

TESTING:

  • New test helper classs MemoryTree. This is typically accessed via self.make_branch_and_memory_tree() in test cases. (Robert Collins)
  • Add start_bzr_subprocess and stop_bzr_subprocess to allow test code to continue running concurrently with a subprocess of bzr. (Andrew Bennetts, Robert Collins)
  • Add a new method Transport.get_smart_client(). This is provided to allow upgrades to a richer interface than the VFS one provided by Transport. (Andrew Bennetts, Martin Pool)

bzr 0.10 2006-08-29

IMPROVEMENTS:
  • 'merge' now takes --uncommitted, to apply uncommitted changes from a tree. (Aaron Bentley)
  • 'bzr add --file-ids-from' can be used to specify another path to use for creating file ids, rather than generating all new ones. Internally, the 'action' passed to smart_add_tree() can return file_ids that will be used, rather than having bzrlib generate new ones. (John Arbash Meinel, #55781)
  • bzr selftest --benchmark now allows a --cache-dir parameter. This will cache some of the intermediate trees, and decrease the setup time for benchmark tests. (John Arbash Meinel)
  • Inverse forms are provided for all boolean options. For example, --strict has --no-strict, --no-recurse has --recurse (Aaron Bentley)
  • Serialize out Inventories directly, rather than using ElementTree. Writing out a kernel sized inventory drops from 2s down to ~350ms. (Robert Collins, John Arbash Meinel)

BUG FIXES:

  • Help diffutils 2.8.4 get along with binary tests (Marien Zwart: #57614)
  • Change LockDir so that if the lock directory doesn't exist when lock_write() is called, an attempt will be made to create it. (John Arbash Meinel, #56974)
  • bzr uncommit preserves pending merges. (John Arbash Meinel, #57660)
  • Active FTP transport now works as intended. (ghozzy, #56472)
  • Really fix mutter() so that it won't ever raise a UnicodeError. It means it is possible for ~/.bzr.log to contain non UTF-8 characters. But it is a debugging log, not a real user file. (John Arbash Meinel, #56947, #53880)
  • Change Command handle to allow Unicode command and options. At present we cannot register Unicode command names, so we will get BzrCommandError('unknown command'), or BzrCommandError('unknown option') But that is better than a UnicodeError + a traceback. (John Arbash Meinel, #57123)
  • Handle TZ=UTC properly when reading/writing revisions. (John Arbash Meinel, #55783, #56290)
  • Use GPG_TTY to allow gpg --cl to work with gpg-agent in a pipeline, (passing text to sign in on stdin). (John Arbash Meinel, #54468)
  • External diff does the right thing for binaries even in foreign languages. (John Arbash Meinel, #56307)
  • Testament handles more cases when content is unicode. Specific bug was in handling of revision properties. (John Arbash Meinel, Holger Krekel, #54723)
  • The bzr selftest was failing on installed versions due to a bug in a new test helper. (John Arbash Meinel, Robert Collins, #58057)

INTERNALS:

  • bzrlib.cache_utf8 contains encode() and decode() functions which can be used to cache the conversion between utf8 and Unicode. Especially helpful for some of the knit annotation code, which has to convert revision ids to utf8 to annotate lines in storage. (John Arbash Meinel)
  • setup.py now searches the filesystem to find all packages which need to be installed. This should help make the life of packagers easier. (John Arbash Meinel)

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. (Erik Bågfors, Michael Ellerman, Martin Pool, #32587)
  • 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. (John Arbash Meinel, #49742)
  • 'bzr revert' no longer toggles the executable bit on win32 (John Arbash Meinel, #45010)
  • 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. (Aaron Bentley, #52227)
  • 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. (James Henstridge, John Arbash Meinel, #4047, #48914)
  • 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. (Olaf Conradi, #44443)

CHANGES:

  • Do not show the None revision in output of bzr ancestry. (Olaf Conradi)
  • Add info on standalone branches without a working tree. (Olaf Conradi, #44155)
  • Fix bug in knits when raising InvalidRevisionId. (Olaf Conradi, #44284)

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. (Olaf Conradi, #42904)

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'. (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.

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. (Matthieu Moy, #3632)
  • 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. (Daniel Silverstone, #4503)
  • 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. (Tollef Fog Heen, Martin Pool, #6413)
  • 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 function. (Robert Collins)

  • LocationConfig now has a set_user_option(key, value) call to save a setting in its matching location section (a new one is created if needed). (Robert Collins)

  • Branch has two new methods, get_push_location and set_push_location to respectively, get and set the push location. (Robert Collins)

  • commands.register_command now takes an optional flag to signal that the registrant is planning to decorate an existing command. When given multiple plugins registering a command is not an error, and the original command class (whether built in or a plugin based one) is returned to the caller. There is a new error 'MustUseDecorated' for signalling when a wrapping command should switch to the original version. (Robert Collins)

  • Some option parsing errors will raise 'BzrOptionError', allowing granular detection for decorating commands. (Robert Collins).

  • Branch.read_working_inventory has moved to WorkingTree.read_working_inventory. This necessitated changes to Branch.get_root_id, and a move of Branch.set_inventory to WorkingTree as well. To make it clear that a WorkingTree cannot always be obtained Branch.working_tree() will raise errors.NoWorkingTree if one cannot be obtained. (Robert Collins)

  • All pending merges operations from Branch are now on WorkingTree. (Robert Collins)

  • The follow operations from Branch have moved to WorkingTree:

    add()
    commit()
    move()
    rename_one()
    unknowns()
    

    (Robert Collins)

  • bzrlib.add.smart_add_branch is now smart_add_tree. (Robert Collins)

  • New "rio" serialization format, similar to rfc-822. (Martin Pool)

  • Rename selftests to bzrlib.tests.test_foo. (John A Meinel, Martin Pool)

  • bzrlib.plugin.all_plugins has been changed from an attribute to a query method. (Robert Collins)

  • New options to read only the table-of-contents of a weave. (Denys Duchier)

  • Raise NoSuchFile when someone tries to add a non-existant file. (Michael Ellerman)

  • Simplify handling of DivergedBranches in cmd_pull(). (Michael Ellerman)

  • Branch.controlfile* logic has moved to lockablefiles.LockableFiles, which is exposed as Branch().control_files. Also this has been altered with the controlfile pre/suffix replaced by simple method names like 'get' and 'put'. (Aaron Bentley, Robert Collins).

  • Deprecated functions and methods can now be marked as such using the bzrlib.symbol_versioning module. Marked method have their docstring updated and will issue a DeprecationWarning using the warnings module when they are used. (Robert Collins)

  • bzrlib.osutils.safe_unicode now exists to provide parameter coercion for functions that need unicode strings. (Robert Collins)

bzr 0.6 2005-10-28

IMPROVEMENTS:

  • pull now takes --verbose to show you what revisions are added or removed (John A Meinel)
  • merge now takes a --show-base option to include the base text in conflicts. (Aaron Bentley)
  • The config files are now read using ConfigObj, so '=' should be used as a separator, not ':'. (Aaron Bentley)
  • New 'bzr commit --strict' option refuses to commit if there are any unknown files in the tree. To commit, make sure all files are either ignored, added, or deleted. (Michael Ellerman)
  • The config directory is now ~/.bazaar, and there is a single file ~/.bazaar/bazaar.conf storing email, editor and other preferences. (Robert Collins)
  • 'bzr add' no longer takes a --verbose option, and a --quiet option has been added that suppresses all output.
  • Improved zsh completion support in contrib/zsh, from Clint Adams.
  • Builtin 'bzr annotate' command, by Martin Pool with improvements from Goffredo Baroncelli.
  • 'bzr check' now accepts -v for verbose reporting, and checks for ghosts in the branch. (Robert Collins)
  • New command 're-sign' which will regenerate the gpg signature for a revision. (Robert Collins)
  • If you set check_signatures=require for a path in ~/.bazaar/branches.conf then bzr will invoke your gpg_signing_command (defaults to gpg) and record a digital signature of your commit. (Robert Collins)
  • New sftp transport, based on Paramiko. (Robey Pointer)
  • 'bzr pull' now accepts '--clobber' which will discard local changes and make this branch identical to the source branch. (Robert Collins)
  • Just give a quieter warning if a plugin can't be loaded, and put the details in .bzr.log. (Martin Pool)
  • 'bzr branch' will now set the branch-name to the last component of the output directory, if one was supplied.
  • If the option post_commit is set to one (or more) python function names (must be in the bzrlib namespace), then they will be invoked after the commit has completed, with the branch and revision_id as parameters. (Robert Collins)
  • Merge now has a retcode of 1 when conflicts occur. (Robert Collins)
  • --merge-type weave is now supported for file contents. Tree-shape changes are still three-way based. (Martin Pool, Aaron Bentley)
  • 'bzr check' allows the first revision on revision-history to have parents - something that is expected for cheap checkouts, and occurs when conversions from baz do not have all history. (Robert Collins).
  • 'bzr merge' can now graft unrelated trees together, if your specify 0 as a base. (Aaron Bentley)
  • 'bzr commit branch' and 'bzr commit branch/file1 branch/file2' now work (Aaron Bentley)
  • Add '.sconsign*' to default ignore list. (Alexander Belchenko)
  • 'bzr merge --reprocess' minimizes conflicts

TESTING:

  • The 'bzr selftest --pattern' option for has been removed, now test specifiers on the command line can be simple strings, or regexps, or both. (Robert Collins)
  • Passing -v to selftest will now show the time each test took to complete, which will aid in analysing performance regressions and related questions. (Robert Collins)
  • 'bzr selftest' runs all tests, even if one fails, unless '--one' is given. (Martin Pool)
  • There is a new method for TestCaseInTempDir, assertFileEqual, which will check that a given content is equal to the content of the named file. (Robert Collins)
  • Fix test suite's habit of leaving many temporary log files in $TMPDIR. (Martin Pool)

INTERNALS:

  • New 'testament' command and concept for making gpg-signatures of revisions that are not tied to a particular internal representation. (Martin Pool).
  • Per-revision properties ('revprops') as key-value associated strings on each revision created when the revision is committed. Intended mainly for the use of external tools. (Martin Pool).
  • Config options have moved from bzrlib.osutils to bzrlib.config. (Robert Collins)
  • Improved command line option definitions allowing explanations for individual options, among other things. Contributed by Magnus Therning.
  • Config options have moved from bzrlib.osutils to bzrlib.config. Configuration is now done via the config.Config interface: Depending on whether you have a Branch, a Location or no information available, construct a *Config, and use its signature_checking, username and user_email methods. (Robert Collins)
  • Plugins are now loaded under bzrlib.plugins, not bzrlib.plugin, and they are made available for other plugins to use. You should not import other plugins during the __init__ of your plugin though, as no ordering is guaranteed, and the plugins directory is not on the python path. (Robert Collins)
  • Branch.relpath has been moved to WorkingTree.relpath. WorkingTree no no longer takes an inventory, rather it takes an option branch parameter, and if None is given will open the branch at basedir implicitly. (Robert Collins)
  • Cleaner exception structure and error reporting. Suggested by Scott James Remnant. (Martin Pool)
  • Branch.remove has been moved to WorkingTree, which has also gained lock_read, lock_write and unlock methods for convenience. (Robert Collins)
  • Two decorators, needs_read_lock and needs_write_lock have been added to the branch module. Use these to cause a function to run in a read or write lock respectively. (Robert Collins)
  • Branch.open_containing now returns a tuple (Branch, relative-path), which allows direct access to the common case of 'get me this file from its branch'. (Robert Collins)
  • Transports can register using register_lazy_transport, and they will be loaded when first used. (Martin Pool)
  • 'pull' has been factored out of the command as WorkingTree.pull(). A new option to WorkingTree.pull has been added, clobber, which will ignore diverged history and pull anyway. (Robert Collins)
  • config.Config has a get_user_option call that accepts an option name. This will be looked up in branches.conf and bazaar.conf as normal. It is intended that this be used by plugins to support options - options of built in programs should have specific methods on the config. (Robert Collins)
  • merge.merge_inner now has tempdir as an optional parameter. (Robert Collins)
  • Tree.kind is not recorded at the top level of the hierarchy, as it was missing on EmptyTree, leading to a bug with merge on EmptyTrees. (Robert Collins)
  • WorkingTree.__del__ has been removed, it was non deterministic and not doing what it was intended to. See WorkingTree.__init__ for a comment about future directions. (Robert Collins/Martin Pool)
  • bzrlib.transport.http has been modified so that only 404 urllib errors are returned as NoSuchFile. Other exceptions will propogate as normal. This allows debuging of actual errors. (Robert Collins)
  • bzrlib.transport.Transport now accepts ONLY url escaped relative paths to apis like 'put', 'get' and 'has'. This is to provide consistent behaviour - it operates on url's only. (Robert Collins)
  • Transports can register using register_lazy_transport, and they will be loaded when first used. (Martin Pool)
  • merge_flex no longer calls conflict_handler.finalize(), instead that is called by merge_inner. This is so that the conflict count can be retrieved (and potentially manipulated) before returning to the caller of merge_inner. Likewise 'merge' now returns the conflict count to the caller. (Robert Collins)
  • revision.revision_graph can handle having only partial history for a revision - that is no revisions in the graph with no parents. (Robert Collins).
  • New builtins.branch_files uses the standard file_list rules to produce a branch and a list of paths, relative to that branch (Aaron Bentley)
  • New TestCase.addCleanup facility.
  • New bzrlib.version_info tuple (similar to sys.version_info), which can be used by programs importing bzrlib.

BUG FIXES:

  • Better handling of branches in directories with non-ascii names. (Joel Rosdahl, Panagiotis Papadakos)
  • Upgrades of trees with no commits will not fail due to accessing [-1] in the revision-history. (Andres Salomon)

bzr 0.1.1 2005-10-12

BUG FIXES:

  • Fix problem in pulling over http from machines that do not allow directories to be listed.
  • Avoid harmless warning about invalid hash cache after upgrading branch format.

PERFORMANCE:

  • Avoid some unnecessary http operations in branch and pull.

bzr 0.1 2005-10-11

NOTES:

  • 'bzr branch' over http initially gives a very high estimate of completion time but it should fall as the first few revisions are pulled in. branch is still slow on high-latency connections.

BUG FIXES:

  • bzr-man.py has been updated to work again. Contributed by Rob Weir.
  • Locking is now done with fcntl.lockf which works with NFS file systems. Contributed by Harald Meland.
  • When a merge encounters a file that has been deleted on one side and modified on the other, the old contents are written out to foo.BASE and foo.SIDE, where SIDE is this or OTHER. Contributed by Aaron Bentley.
  • Export was choosing incorrect file paths for the content of the tarball, this has been fixed by Aaron Bentley.
  • Commit will no longer commit without a log message, an error is returned instead. Contributed by Jelmer Vernooij.
  • If you commit a specific file in a sub directory, any of its parent directories that are added but not listed will be automatically included. Suggested by Michael Ellerman.
  • bzr commit and upgrade did not correctly record new revisions for files with only a change to their executable status. bzr will correct this when it encounters it. Fixed by Robert Collins
  • HTTP tests now force off the use of http_proxy for the duration. Contributed by Gustavo Niemeyer.
  • Fix problems in merging weave-based branches that have different partial views of history.
  • Symlink support: working with symlinks when not in the root of a bzr tree was broken, patch from Scott James Remnant.

IMPROVEMENTS:

  • 'branch' now accepts a --basis parameter which will take advantage of local history when making a new branch. This allows faster branching of remote branches. Contributed by Aaron Bentley.
  • New tree format based on weave files, called version 5. Existing branches can be upgraded to this format using 'bzr upgrade'.
  • Symlinks are now versionable. Initial patch by Erik Toubro Nielsen, updated to head by Robert Collins.
  • Executable bits are tracked on files. Patch from Gustavo Niemeyer.
  • 'bzr status' now shows unknown files inside a selected directory. Patch from Heikki Paajanen.
  • Merge conflicts are recorded in .bzr. Two new commands 'conflicts' and 'resolve' have needed added, which list and remove those merge conflicts respectively. A conflicted tree cannot be committed in. Contributed by Aaron Bentley.
  • 'rm' is now an alias for 'remove'.
  • Stores now split out their content in a single byte prefixed hash, dropping the density of files per directory by 256. Contributed by Gustavo Niemeyer.
  • 'bzr diff -r branch:URL' will now perform a diff between two branches. Contributed by Robert Collins.
  • 'bzr log' with the default formatter will show merged revisions, indented to the right. Initial implementation contributed by Gustavo Niemeyer, made incremental by Robert Collins.

INTERNALS:

  • Test case failures have the exception printed after the log for your viewing pleasure.
  • InventoryEntry is now an abstract base class, use one of the concrete InventoryDirectory etc classes instead.
  • Branch raises an UnsupportedFormatError when it detects a bzr branch it cannot understand. This allows for precise handling of such circumstances.
  • Remove RevisionReference class; Revision.parent_ids is now simply a list of their ids and parent_sha1s is a list of their corresponding sha1s (for old branches only at the moment.)
  • New method-object style interface for Commit() and Fetch().
  • Renamed Branch.last_patch() to Branch.last_revision(), since we call them revisions not patches.
  • Move copy_branch to bzrlib.clone.copy_branch. The destination directory is created if it doesn't exist.
  • Inventories now identify the files which were present by giving the revision of that file.
  • Inventory and Revision XML contains a version identifier. This must be consistent with the overall branch version but allows for more flexibility in future upgrades.

TESTING:

  • Removed testsweet module so that tests can be run after bzr installed by 'bzr selftest'.
  • 'bzr selftest' command-line arguments can now be partial ids of tests to run, e.g. bzr selftest test_weave

bzr 0.0.9 2005-09-23

BUG FIXES:

  • Fixed "branch -r" option.
  • Fix remote access to branches containing non-compressed history. (Robert Collins).
  • Better reliability of http server tests. (John Arbash-Meinel)
  • Merge graph maximum distance calculation fix. (Aaron Bentley)
  • Various minor bug in windows support have been fixed, largely in the test suite. Contributed by Alexander Belchenko.

IMPROVEMENTS:

  • Status now accepts a -r argument to give status between chosen revisions. Contributed by Heikki Paajanen.
  • Revision arguments no longer use +/-/= to control ranges, instead there is a 'before' namespace, which limits the successive namespace. For example '$ bzr log -r date:yesterday..before:date:today' will select everything from yesterday and before today. Contributed by Robey Pointer
  • There is now a bzr.bat file created by distutils when building on Windows. Contributed by Alexander Belchenko.

INTERNALS:

  • Removed uuid() as it was unused.
  • Improved 'fetch' code for pulling revisions from one branch into another (used by pull, merged, etc.)

bzr 0.0.8 2005-09-20

IMPROVEMENTS:

  • Adding a file whose parent directory is not versioned will implicitly add the parent, and so on up to the root. This means you should never need to explictly add a directory, they'll just get added when you add a file in the directory. Contributed by Michael Ellerman.
  • Ignore .DS_Store (contains Mac metadata) by default. (Nir Soffer)
  • If you set BZR_EDITOR in the environment, it is checked in preference to EDITOR and the config file for the interactive commit editing program. Related to this is a bugfix where a missing program set in EDITOR would cause editing to fail, now the fallback program for the operating system is still tried.
  • Files that are not directories/symlinks/regular files will no longer cause bzr to fail, it will just ignore them by default. You cannot add them to the tree though - they are not versionable.

INTERNALS:

  • Refactor xml packing/unpacking.

BUG FIXES:

  • Fixed 'bzr mv' by Ollie Rutherfurd.
  • Fixed strange error when trying to access a nonexistent http branch.
  • Make sure that the hashcache gets written out if it can't be read.

PORTABILITY:

  • Various Windows fixes from Ollie Rutherfurd.
  • Quieten warnings about locking; patch from Matt Lavin.

bzr-0.0.7 2005-09-02

NEW FEATURES:

  • bzr shell-complete command contributed by Clint Adams to help with intelligent shell completion.
  • New expert command bzr find-merge-base for debugging merges.

ENHANCEMENTS:

  • Much better merge support.
  • merge3 conflicts are now reported with markers like '<<<<<<<' (seven characters) which is the same as CVS and pleases things like emacs smerge.

BUG FIXES:

  • bzr upgrade no longer fails when trying to fix trees that mention revisions that are not present.
  • Fixed bugs in listing plugins from bzr plugins.
  • Fix case of $EDITOR containing options for the editor.
  • Fix log -r refusing to show the last revision. (Patch from Goffredo Baroncelli.)

CHANGES:

  • bzr log --show-ids shows the revision ids of all parents.
  • Externally provided commands on your $BZRPATH no longer need to recognize --bzr-usage to work properly, and can just handle --help themselves.

LIBRARY:

  • Changed trace messages to go through the standard logging framework, so that they can more easily be redirected by libraries.

bzr-0.0.6 2005-08-18

NEW FEATURES:

  • Python plugins, automatically loaded from the directories on BZR_PLUGIN_PATH or ~/.bzr.conf/plugins by default.
  • New 'bzr mkdir' command.
  • Commit mesage is fetched from an editor if not given on the command line; patch from Torsten Marek.
  • bzr log -m FOO displays commits whose message matches regexp FOO.
  • bzr add with no arguments adds everything under the current directory.
  • bzr mv does move or rename depending on its arguments, like the Unix command.
  • bzr missing command shows a summary of the differences between two trees. (Merged from John Arbash-Meinel.)
  • An email address for commits to a particular tree can be specified by putting it into .bzr/email within a branch. (Based on a patch from Heikki Paajanen.)

ENHANCEMENTS:

  • Faster working tree operations.

CHANGES:

  • 3rd-party modules shipped with bzr are copied within the bzrlib python package, so that they can be installed by the setup script without clashing with anything already existing on the system. (Contributed by Gustavo Niemeyer.)
  • Moved plugins directory to bzrlib/, so that there's a standard plugin directory which is not only installed with bzr itself but is also available when using bzr from the development tree. BZR_PLUGIN_PATH and DEFAULT_PLUGIN_PATH are then added to the standard plugins directory.
  • When exporting to a tarball with bzr export --format tgz, put everything under a top directory rather than dumping it into the current directory. This can be overridden with the --root option. Patch from William Dodé and John Meinel.
  • New bzr upgrade command to upgrade the format of a branch, replacing bzr check --update.
  • Files within store directories are no longer marked readonly on disk.
  • Changed bzr log output to a more compact form suggested by John A Meinel. Old format is available with the --long or -l option, patched by William Dodé.
  • By default the commit command refuses to record a revision with no changes unless the --unchanged option is given.
  • The --no-plugins, --profile and --builtin command line options must come before the command name because they affect what commands are available; all other options must come after the command name because their interpretation depends on it.
  • branch and clone added as aliases for branch.
  • Default log format is back to the long format; the compact one is available with --short.

BUG FIXES:

  • Fix bugs in committing only selected files or within a subdirectory.

bzr-0.0.5 2005-06-15

CHANGES:

  • bzr with no command now shows help rather than giving an error. Suggested by Michael Ellerman.
  • bzr status output format changed, because svn-style output doesn't really match the model of bzr. Now files are grouped by status and can be shown with their IDs. bzr status --all shows all versioned files and unknown files but not ignored files.
  • bzr log runs from most-recent to least-recent, the reverse of the previous order. The previous behaviour can be obtained with the --forward option.
  • bzr inventory by default shows only filenames, and also ids if --show-ids is given, in which case the id is the second field.

ENHANCEMENTS:

  • New 'bzr whoami --email' option shows only the email component of the user identification, from Jo Vermeulen.
  • New bzr ignore PATTERN command.
  • Nicer error message for broken pipe, interrupt and similar conditions that don't indicate an internal error.
  • Add .*.sw[nop] .git .*.tmp *,v to default ignore patterns.
  • Per-branch locks keyed on .bzr/branch-lock, available in either read or write mode.
  • New option bzr log --show-ids shows revision and file ids.
  • New usage bzr log FILENAME shows only revisions that affected that file.
  • Changed format for describing changes in bzr log -v.
  • New option bzr commit --file to take a message from a file, suggested by LarstiQ.
  • New syntax bzr status [FILE...] contributed by Bartosz Oler. File may be in a branch other than the working directory.
  • bzr log and bzr root can be given an http URL instead of a filename.
  • Commands can now be defined by external programs or scripts in a directory on $BZRPATH.
  • New "stat cache" avoids reading the contents of files if they haven't changed since the previous time.
  • If the Python interpreter is too old, try to find a better one or give an error. Based on a patch from Fredrik Lundh.
  • New optional parameter bzr info [BRANCH].
  • New form bzr commit SELECTED to commit only selected files.
  • New form bzr log -r FROM:TO shows changes in selected range; contributed by John A Meinel.
  • New option bzr diff --diff-options 'OPTS' allows passing options through to an external GNU diff.
  • New option bzr add --no-recurse to add a directory but not their contents.
  • bzr --version now shows more information if bzr is being run from a branch.

BUG FIXES:

  • Fixed diff format so that added and removed files will be handled properly by patch. Fix from Lalo Martins.
  • Various fixes for files whose names contain spaces or other metacharacters.

TESTING:

  • Converted black-box test suites from Bourne shell into Python; now run using ./testbzr. Various structural improvements to the tests.
  • testbzr by default runs the version of bzr found in the same directory as the tests, or the one given as the first parameter.
  • testbzr also runs the internal tests, so the only command required to check is just ./testbzr.
  • testbzr requires python2.4, but can be used to test bzr running under a different version.
  • Tests added for many other changes in this release.

INTERNAL:

  • Included ElementTree library upgraded to 1.2.6 by Fredrik Lundh.
  • Refactor command functions into Command objects based on HCT by Scott James Remnant.
  • Better help messages for many commands.
  • Expose bzrlib.open_tracefile() to start the tracefile; until this is called trace messages are just discarded.
  • New internal function find_touching_revisions() and hidden command touching-revisions trace the changes to a given file.
  • Simpler and faster compare_inventories() function.
  • bzrlib.open_tracefile() takes a tracefilename parameter.
  • New AtomicFile class.
  • New developer commands added, modified.

PORTABILITY:

  • Cope on Windows on python2.3 by using the weaker random seed. 2.4 is now only recommended.

bzr-0.0.4 2005-04-22

ENHANCEMENTS:

  • 'bzr diff' optionally takes a list of files to diff. Still a bit basic. Patch from QuantumG.
  • More default ignore patterns.
  • New 'bzr log --verbose' shows a list of files changed in the changeset. Patch from Sebastian Cote.
  • Roll over ~/.bzr.log if it gets too large.
  • Command abbreviations 'ci', 'st', 'stat', '?' based on a patch by Jason Diamon.
  • New 'bzr help commands' based on a patch from Denys Duchier.

CHANGES:

  • User email is determined by looking at $BZREMAIL or ~/.bzr.email or $EMAIL. All are decoded by the locale preferred encoding. If none of these are present user@hostname is used. The host's fully-qualified name is not used because that tends to fail when there are DNS problems.
  • New 'bzr whoami' command instead of username user-email.

BUG FIXES:

  • Make commit safe for hardlinked bzr trees.
  • Some Unicode/locale fixes.
  • Partial workaround for difflib.unified_diff not handling trailing newlines properly.

INTERNAL:

  • Allow docstrings for help to be in PEP0257 format. Patch from Matt Brubeck.
  • More tests in test.sh.
  • Write profile data to a temporary file not into working directory and delete it when done.
  • Smaller .bzr.log with process ids.

PORTABILITY:

  • Fix opening of ~/.bzr.log on Windows. Patch from Andrew Bennetts.
  • Some improvements in handling paths on Windows, based on a patch from QuantumG.

bzr-0.0.3 2005-04-06

ENHANCEMENTS:

  • New "directories" internal command lists versioned directories in the tree.
  • Can now say "bzr commit --help".
  • New "rename" command to rename one file to a different name and/or directory.
  • New "move" command to move one or more files into a different directory.
  • New "renames" command lists files renamed since base revision.
  • New cat command contributed by janmar.

CHANGES:

  • .bzr.log is placed in $HOME (not pwd) and is always written in UTF-8. (Probably not a completely good long-term solution, but will do for now.)

PORTABILITY:

  • Workaround for difflib bug in Python 2.3 that causes an exception when comparing empty files. Reported by Erik Toubro Nielsen.

INTERNAL:

  • Refactored inventory storage to insert a root entry at the top.

TESTING:

  • Start of shell-based black-box testing in test.sh.

bzr-0.0.2.1

PORTABILITY:

  • Win32 fixes from Steve Brown.

bzr-0.0.2 "black cube" 2005-03-31

ENHANCEMENTS:

  • Default ignore list extended (see bzrlib/__init__.py).
  • Patterns in .bzrignore are now added to the default ignore list, rather than replacing it.
  • Ignore list isn't reread for every file.
  • More help topics.
  • Reinstate the 'bzr check' command to check invariants of the branch.
  • New 'ignored' command lists which files are ignored and why; 'deleted' lists files deleted in the current working tree.
  • Performance improvements.
  • New global --profile option.
  • Ignore patterns like './config.h' now correctly match files in the root directory only.

bzr-0.0.1 2005-03-26

ENHANCEMENTS:

  • More information from info command.
  • Can now say "bzr help COMMAND" for more detailed help.
  • Less file flushing and faster performance when writing logs and committing to stores.
  • More useful verbose output from some commands.

BUG FIXES:

  • Fix inverted display of 'R' and 'M' during 'commit -v'.

PORTABILITY:

  • Include a subset of ElementTree-1.2.20040618 to make installation easier.
  • Fix time.localtime call to work with Python 2.3 (the minimum supported).

bzr-0.0.0.69 2005-03-22

ENHANCEMENTS:

  • First public release.
  • Storage of local versions: init, add, remove, rm, info, log, diff, status, etc.
