git version required is now 1.5.6.
prune-older command now keeps the most recent save in each period group (day, week, month, ...) rather than the oldest.
bup now adds a zero-padded suffix to the names of saves with the same timestamp (e.g. 1970-01-01-214640-07) in order to avoid duplicates. The sequence number currently represents the save's reversed position in default
git rev-list order, so that given:
In the normal case, the -10 save would be the next save made after -09 (and the -09 save would be the single parent commit for -10).
bup is not currently compatible with Python 3 and will now refuse to run if the Python version is not 2 unless
BUP_ALLOW_UNEXPECTED_PYTHON_VERSION=true is set in the environment (which can be useful for development and testing).
bup ls -s now reports the tree hash for commits unless
--commit-hash is also specified.
bup get has been added. This command allows the transfer or rewriting of data within and between repositories, local or remote. Among other things, it can be used to append remote saves to a local branch, which by extension supports merging repositories. See
bup-get(1) for further information, and please note, this is a new EXPERIMENTAL command that can (intentionally) modify your data in destructive ways. It is potentially much more dangerous than most
bup commands. Treat with caution.
bup can now restore directly from a remote repository via
bup restore -r host:path .... See
bup-restore(1) for more information.
bup ls can now report information for remote repositories via
bup ls -r host:path .... See
bup-ls(1) for more information.
bup should respect the git pack.packSizeLimit setting when writing packfiles, though at the moment it will only affect a remote repository when the option is set there directly.
bup save now stores the size for all links and normal files. For directories saved using this new format retrieving file sizes for larger files should be notably less expensive. Among other things this may improve the performance of commands like
bup ls -l or
find /some/fuse/dir -ls.
The VFS (Virtual File System) that underlies many operations, and provides the basis for commands like
ls, etc. has been rewritten in a way that makes remote repository access easier, should decrease the memory footprint in some cases (e.g. for bup fuse), and should make it easier to provide more selective caching. At the moment, data is just evicted at random once a threshold is reached.
--noop <--blobs|--tree> option has been added to
bup split which prints the resulting id without storing the data in the repository.
bup handles output from subprocesses (diagnostics, progress, etc.) has been adjusted in a way that should make it less likely that bup might continue running after the main process has exited, say via a C-c (SIGINT).
bup should now respect the specified compression level when writing to a remote repository.
bup restore now creates FIFOs with mkfifo, not mknod, which is more portable. The previous approach did not work correctly on (at least) some versions of NetBSD.
bup should no longer just crash when it encounters a commit with a "mergetag" header. For the moment, it just ignores them, and they'll be discarded whenever
bup rewrites a commit, say via the
The bloom command should now end progress messages with \r, not \n, which avoids leaving spurious output lines behind at exit.
A missing space has been added to the
bup split --bench output.
Various Python version compatibility problems have been fixed, including some of the incompatibilities introduced by Python 3.
Some issues with mincore on WSL have been fixed.
Some Android build incompatibilities have been fixed.
The tests no longer assume pwd is in /bin.
The tests should be less sensitive to the locale.
test-meta should no longer try to apply chattr +T to files. 'T' only works for directories, and newer Linux kernels actually reject the attempt (as of at least 4.12, and maybe 4.10).
test-rm should no longer fail when newer versions of git automatically create packed-refs.
test-sparse-files should be less likely to fail when run inside a container.
test-xdev now use separate files for their loopback mounts. Previously each was mounting the same image twice, which could produce the same device number.
