bzr 1.15

1.15rc1:2009-05-16
1.15:2009-05-22
1.15.1:2009-06-09

The smart server will no longer raise ‘NoSuchRevision’ when streaming content with a size mismatch in a reconstructed graph search. New command bzr dpush. Plugins can now define their own annotation tie-breaker when two revisions introduce the exact same line.

Changes from 1.15.1 to 1.15.2

  • Use zdll on Windows to build _chk_map_pyx extension. (Alexander Belchenko)

Changes from 1.15final to 1.15.1

  • Translate errors received from a smart server in response to a BzrDirFormat.initialize or BzrDirFormat.initialize_ex request. This was causing tracebacks even for mundane errors like PermissionDenied. (Andrew Bennetts, #381329)

Changes from 1.15rc1 to 1.15final

  • No changes

Compatibility Breaks

  • bzr ls is no longer recursive by default. To recurse, use the new -R option. The old --non-recursive option has been removed. If you alias ls to ls -R, you can disable recursion using --no-recursive instead. (Ian Clatworthy)

New Features

  • New command bzr dpush that can push changes to foreign branches (svn, git) without setting custom bzr-specific metadata. (Jelmer Vernooij)
  • The new development format --development6-rich-root now supports stacking. We chose not to use a new format marker, since old clients will just fail to open stacked branches, the same as if we used a new format flag. (John Arbash Meinel, #373455)
  • Plugins can now define their own annotation tie-breaker when two revisions introduce the exact same line. See bzrlib.annotate._break_annotation_tie Be aware though that this is temporary, private (as indicated by the leading ‘_’) and a first step to address the problem. (Vincent Ladeuil, #348459)
  • New command bzr dpush that can push changes to foreign branches (svn, git) without setting custom bzr-specific metadata. (Jelmer Vernooij)
  • bzr send will now check the child_submit_format setting in the submit branch to determine what format to use, if none was specified on the command-line. (Jelmer Vernooij)

Improvements

  • -Dhpss output now includes the number of VFS calls made to the remote server. (Jonathan Lange)
  • --coverage works for code running in threads too. (Andrew Bennets, Vincent Ladeuil)
  • bzr pull now has a --local option to only make changes to the local branch, and not the bound master branch. (Gary van der Merwe, #194716)
  • bzr rm * is now as fast as bzr rm * --keep. (Johan Walles, #180116)

Bug Fixes

  • Adding now works properly when path contains a symbolic link. (Geoff Bache, #183831)
  • An error is now raised for unknown eol values. (Brian de Alwis, #358199)
  • bzr merge --weave will now generate a conflict if one side deletes a line, and the other side modifies the line. (John Arbash Meinel, #328171)
  • bzr reconfigure --standalone no longer raises IncompatibleRepositories. (Martin von Gagern, #248932)
  • bzr send works to send emails again using MAPI. (Neil Martinsen-Burrell, #346998)
  • Check for missing parent inventories in StreamSink. This prevents incomplete stacked branches being created by 1.13 bzr:// and bzr+ssh:// clients (which have bug #354036). Instead, the server now causes those clients to send the missing records. (Andrew Bennetts)
  • Correctly handle http servers proposing multiple authentication schemes. (Vincent Ladeuil, #366107)
  • End-Of-Line content filters are now loaded correctly. (Ian Clatworthy, Brian de Alwis, #355280)
  • Fix a bug in the pure-python GroupCompress code when handling copies longer than 64KiB. (John Arbash Meinel, #364900)
  • Fix TypeError in running bzr break-lock on some URLs. (Alexander Belchenko, Martin Pool, #365891)
  • Non-recursive bzr ls now works properly when a path is specified. (Jelmer Vernooij, #357863)
  • ssh usernames (defined in ~/.ssh/config) are honoured for bzr+ssh connections. (Vincent Ladeuil, #367726)
  • Several bugs related to unicode symlinks have been fixed and the test suite enhanced to better catch regressions for them. (Vincent Ladeuil)
  • The smart server will no longer raise ‘NoSuchRevision’ when streaming content with a size mismatch in a reconstructed graph search: it assumes that the client will make sure it is happy with what it got, and this sort of mismatch is normal for stacked environments. bzr 1.13.0/1 will stream from unstacked branches only - in that case not getting all the content expected would be a bug. However the graph search is how we figured out what we wanted, so a mismatch is both odd and unrecoverable without starting over, and starting over will end up with the same data as if we just permitted the mismatch. If data is gc’d, doing a new search will find only the truncated data, so sending only the truncated data seems reasonable. bzr versions newer than this will stream from stacked branches and check the stream to find missing content in the stacked-on branch, and thus will handle the situation implicitly. (Robert Collins, #360791)
  • Upgrading to, or fetching into a ‘rich-root’ format will now correctly set the root data the same way that reconcile does. (Robert Collins, #368921)
  • Using unicode Windows API to obtain command-line arguments. (Alexander Belchenko, #375934)

Documentation

API Changes

  • InterPackRepo.fetch and RepoFetcher now raise NoSuchRevision instead of InstallFailed when they detect a missing revision. InstallFailed itself has been deleted. (Jonathan Lange)
  • Not passing arguments to bzrlib.commands.main() will now grab the arguments from osutils.get_unicode_argv() which has proper support for unicode arguments on windows. Further, the supplied arguments are now required to be unicode strings, rather than user_encoded strings. (Alexander Belchenko)

Internals

  • bzrlib.branch.Branch.set_parent is now present on the base branch class and will call _set_parent_location after doing unicode encoding. (Robert Collins)
  • bzrlib.remote.RemoteBranch._set_parent_location will use a new verb Branch.set_parent_location removing further VFS operations. (Robert Collins)
  • bzrlib.bzrdir.BzrDir._get_config now returns a TransportConfig or similar when the dir supports configuration settings. The base class defaults to None. There is a matching new server verb BzrDir.get-config_file to reduce roundtrips for getting BzrDir configuration. (Robert Collins)
  • bzrlib.tests.ExtendedTestResult has new methods startTests called before the first test is started, done called after the last test completes, and a new parameter strict. (Robert Collins)
  • -Dhpss when passed to bzr will cause a backtrace to be printed when VFS operations are started on a smart server repository. This should not occur on regular push and pull operations, and is a key indicator for performance regressions. (Robert Collins)
  • -Dlock when passed to the selftest (e.g. bzr -Dlock selftest) will cause mismatched physical locks to cause test errors rather than just reporting to the screen. (Robert Collins)
  • -Dprogress will cause pdb to start up if a progress view jumps backwards. (Robert Collins)
  • Fallback CredentialStore instances registered with fallback=True are now be able to provide credentials if obtaining credentials via ~/.bazaar/authentication.conf fails. (Jelmer Vernooij, Vincent Ladeuil, #321918)
  • New hook Lock.lock_broken which runs when a lock is broken. This is mainly for testing that lock/unlock are balanced in tests. (Vincent Ladeuil)
  • New MergeDirective hook ‘merge_request_body’ allows hooks to supply or alter a body for the message produced by bzr send.
  • New smart server verb BzrDir.initialize_ex which implements a refactoring to the core of clone allowing less round trips on new branches. (Robert Collins)
  • New method Tags.rename_revisions that can rename revision ids tags are pointing at. (Jelmer Vernooij)
  • Updated the bundled ConfigObj library to 4.6.0 (Matt Nordhoff)

Testing

  • bzr selftest will now fail if lock/unlock are not correctly balanced in tests. Using -Dlock will turn the related failures into warnings. (Vincent Ladeuil, Robert Collins)
