brz 3.1.0





External Compatibility Breaks

  • The brz init-repo command has been renamed to brz init-shared-repo to emphasize that it creates shared repositories rather than just any kind of repository. (Jelmer Vernooij)

New Features

  • A new brz land command can merge merge proposals on Launchpad, GitHub and GitLab sites. (Jelmer Vernooij, #1816213)

  • The ‘patch’ command is now bundled with brz. Imported from bzrtools by Aaron Bentley. (Jelmer Vernooij)

  • The ‘quilt’ plugin, extracted from brz-debian, is now bundled. (Jelmer Vernooij)

  • A new calculate_revnos configuration option (defaults to enabled) can be used to disable revno display for branch formats that do not natively store revnos. This speeds up brz log on the Samba git branch by 33%. (Jelmer Vernooij)

  • Directly read mtab rather than using psutil when trying to figure out filesystem types. This removes a dependency that not all users may have installed and speeds up import time since psutil brings in various other modules. (Jelmer Vernooij)

  • brz diff now has a –color argument that can write color diff output. This is based on the cdiff code in bzrtools by Aaron Bentley. (Jelmer Vernooij, #376594)

  • Information about tree references can now be updated on remote branches. (Jelmer Vernooij)

  • Warn the user when they attempt to use Breezy in a Subversion working copy. (Jelmer Vernooij)

  • Add a basic Mercurial plugin that mentions that .hg repositories are unsupported when the user attempts to access one. (Jelmer Vernooij)

  • The 2a format now officially supports storing tree references. It always partially supported storing tree reference data, and would happily pull in tree reference data from other repository formats. (Jelmer Vernooij)

  • A new fossil plugin has been added that warns users when they attempt to access Fossil repositories. (Jelmer Vernooij, #1848821)

  • When pushing to Git repositories, symrefs are now followed. (Jelmer Vernooij, #1800393)

  • New brz clone command, which clones everything under a control directory. I.e. all colocated branches, like git clone. (Jelmer Vernooij, #831939)

  • brz sprout is now an alias for brz branch. (Jelmer Vernooij)

  • brz branch now accepts a -b flag with the name of the colocated branch to sprout. (Jelmer Vernooij, #1869977)

  • Add a breezy.__main__ module so that python3 -m breezy works. (Jelmer Vernooij)


  • A new --commit-message option has been added to brz propose, for hosting sites that support it. (Jelmer Vernooij)

  • Automatically upgrade to branch format 8 when setting branch references. (Jelmer Vernooij)

  • The ssh configuration variable can be used to set the default SSH implementation. (Jelmer Vernooij, #650757)

  • locks.steal_dead is now enabled by default. (Jelmer Vernooij, #220464)

  • The substitution variables for the change_editor configuration option are now “{old_path}” and “{new_path}” rather than “@old_path” and “@new_path”. The former is more consistent with the way substitutions work in other configuration options. The old syntax is still supported. (Jelmer Vernooij, #708718)

  • The brz inventory command now accepts a --include-root argument to show the tree root. (Jelmer Vernooij)

  • Fix support for reading Git repositories over HTTP without a smart server. (Jelmer Vernooij)

  • CVS pserver URLs now indicate that the pserver protocol is not supported. (Jelmer Vernooij)

  • Git repositories with submodules can now be imported into 2a branches; submodules are converted to nested trees. (Jelmer Vernooij, #402814)

  • Python 3 is now used by default to run scripts, etc. from the makefile. (Jelmer Vernooij)

  • .git/config is now consulted to determine the users’ identity for commits, and the gpg_signing_key. (Jelmer Vernooij)

  • Ignore special files (fifos, block/character devices, sockets) when finding changes in Git working trees. (Jelmer Vernooij, #1857244)

  • Parse error messages from stderr when a remote Git server hangs up. (Jelmer Vernooij)

Bug Fixes

  • Print a sensible error message when conversion for an option fails (i.e. when a non-int is specified as the value for an integer parameter) (#237844, Jelmer Vernooij)

  • Don’t include timestamps in filenames when reporting on binary files in diff. (Jelmer Vernooij, #71307)

  • Ignore UnknownFormatErrors when scanning for control directories. (Jelmer Vernooij, #468332)

  • Fix fetching from remote git repositories in brz git-import. (Jelmer Vernooij, #1836238)

  • A new TreeEntry.is_unmodified method has added, which allows merge to check for unmodified files without relying on the .revision attribute that is not available for Git trees. This fixes LCA merges for Git repositories. (Jelmer Vernooij, #1826663)

  • Fix passing of directories in specific_files to GitWorkingTree.iter_entries_by_dir(). (Jelmer Vernooij, #1844054)

  • Fix brz diff --using when {old_path} and {new_path} are not specified in the template. (#1847915, Jelmer Vernooij)

  • Ignore ghost tags when interacting with remote Git repositories. (Jelmer Vernooij)

  • Fix setup_ui=False when initializing Breezy. (Jelmer Vernooij, #1852647)

  • Fix backwards compatibility with Bazaar by supporting the $BZR_EMAIL variable. (Jelmer Vernooij, #1869178)

  • Cope with non-ascii characters in Git signatures. (Jelmer Vernooij, #1869533)

  • Fix use of proxy_bypass on Python 3. (Jelmer Vernooij, #1878698)

  • Create $XDG_HOME_DIR if it does not exist. (Jelmer Vernooij)


API Changes

  • New Tree.get_transform method for getting a TreeTransform object. (Jelmer Vernooij)

  • The Tree.get_root_id method has been removed. Use Tree.path2id('') instead. (Jelmer Vernooij)

  • Repository.find_branches now returns an iterator rather than a list. (Jelmer Vernooij, #413970)

  • New Tree.get_nested_tree method for retrieving a nested tree. (Jelmer Vernooij)

  • The ControlDirFormat.register_server_prober method has been removed. Instead, probers can now have a priority method to influence when they are run. (Jelmer Vernooij)

  • New urlutils.strip_segment_parameters function for stripping segment parameters from a URL. (Jelmer Vernooij)

  • Tree.id2path has a new optional argument recurse, that determines whether it scans through nested trees. (Jelmer Vernooij)

  • VersionedFiles.add_content can now be used to add content from ContentFactory objects. (Jelmer Vernooij)
