bzr 2.0.6


The sixth release in our 2.0 series addresses several user-inconvenience bugs. None are critical, but upgrading is recommended for all users on earlier 2.0 releases.

Bug Fixes

  • Additional merges after an unrelated branch has been merged with its history no longer crash when deleted files are involved. (Vincent Ladeuil, John Arbash Meinel, #375898)
  • bzr add SYMLINK/FILE now works properly when the symlink points to a previously-unversioned directory within the tree: the directory is marked versioned too. (Martin Pool, #192859)
  • bzr commit SYMLINK now works, rather than trying to commit the target of the symlink. (Martin Pool, John Arbash Meinel, #128562)
  • bzr revert now only takes write lock on working tree, instead of on both working tree and branch. (Danny van Heumen, #498409)
  • bzr upgrade now creates the backup.bzr directory with the same permissions as .bzr directory on a POSIX OS. (Parth Malwankar, #262450)
  • Don’t traceback trying to unversion children files of an already unversioned directory. (Vincent Ladeuil, #494221)
  • Don’t traceback when a lockdir’s held/info file is corrupt (e.g. contains only NUL bytes). Instead warn the user, and allow bzr break-lock to remove it. (Andrew Bennetts, #619872)
  • Fix AttributeError on parent.children when adding a file under a directory that was a symlink in the previous commit. (Martin Pool, #192859)
  • Prevent CHKMap.apply_delta from generating non-canonical CHK maps, which can result in “missing referenced chk root keys” errors when fetching from repositories with affected revisions. (Andrew Bennetts, #522637)
  • Raise ValueError instead of a string exception. (John Arbash Meinel, #586926)
  • Reduce peak memory by one copy of compressed text. (John Arbash Meinel, #566940)
  • Repositories accessed via a smart server now reject being stacked on a repository in an incompatible format, as is the case when accessing them via other methods. This was causing fetches from those repositories via a smart server (e.g. using bzr branch) to receive invalid data. (Andrew Bennetts, #562380)
  • Selftest with versions of subunit that support stopTestRun will no longer error. This error was caused by 2.0 not being updated when upstream python merged the end of run patch, which chose stopTestRun rather than done. (Robert Collins, #571437)
  • When passing a file to UTF8DirReader make sure to close the current directory file handle after the chdir fails. Otherwise when passing many filenames into a command line bzr status we would leak descriptors. (John Arbash Meinel, #583486)


  • build_tree_contents can create symlinks. (Martin Pool, John Arbash Meinel)
