Notable changes in 0.31 (since 0.30.1)

  • Python 3 is now supported, and Python 2 support is deprecated. It's possible that we'll stop new development for Python 2 fairly soon. If so, we'll probably continue to fix bugs in the last Python 2 compatible version for a while, but please make plans to migrate.

  • bup features has been added. It reports information about bup itself, including the Python version, and the current availability of features like readline or support for POSIX ACLs.

May require attention

  • bup now relies on libacl directly instead of python-pylibacl, which will require installing the relevant packages (e.g. libacl1-dev) before building.

  • bup now relies on libreadline directly instead of python's built-in support, which will require installing the relevant packages (e.g. libreadline-dev) before building.

  • bup version --tag has been removed. It was actually a synonym for bup version, which still works fine. The fact that the version may have a corresponding git tag is no longer relevant to the command.

  • git describe style strings will no longer appear in the bup version for non-release builds. The version in that case will currently just be formatted as PENDING_RELEASE~HASH, where ~ has the Debian semantics, for example, 0.31~5ac3821c0f1fbd6a1b1742e91ffd556cd1116041). This is part of the fix for the issue with varying git archive content mentioned below.

General

  • bup fsck should now avoid displaying par2 errors when testing it for parallel processing support.

  • The documentation for the hashsplit algorithm in DESIGN has been updated to reflect quirks of the implementation, which didn't quite match the original specification.

Bugs

  • When running bup on with a remote ssh ForceCommand, bup should now respect that setting when running sub-commands.

  • It should no longer be possible for the content of archives generated by git archive (including releases retrieved from github) to vary based on the current set of repository refs (tags, branches, etc.). Previously archives generated from the same tag could differ slightly in content.

Build and install

  • bup itself is now located in now located in the cmd/ directory in the install tree and finds sub-commands, etc. relative to its own location.

  • The metadata tests should no longer fail on systems with SELinux enabled.
