2 Notable changes in 0.30 as compared to 0.29.3
3 =============================================
8 * The minimum `git` version required is now 1.5.6.
10 * The `prune-older` command now keeps the most recent save in each
11 period group (day, week, month, ...) rather than the oldest.
13 * `bup` now adds a zero-padded suffix to the names of saves with the
14 same timestamp (e.g. 1970-01-01-214640-07) in order to avoid
15 duplicates. The sequence number currently represents the save's
16 reversed position in default `git rev-list` order, so that given:
18 /foo/1970-01-01-214640-09
19 /foo/1970-01-01-214640-10
21 In the normal case, the -10 save would be the next save made after
22 -09 (and the -09 save would be the single parent commit for -10).
24 * `bup` is not currently compatible with Python 3 and will now refuse
25 to run if the Python version is not 2 unless
26 `BUP_ALLOW_UNEXPECTED_PYTHON_VERSION=true` is set in the environment
27 (which can be useful for development and testing).
29 * `bup ls -s` now reports the tree hash for commits unless
30 `--commit-hash` is also specified.
35 * `bup get` has been added. This command allows the transfer or
36 rewriting of data within and between repositories, local or remote.
37 Among other things, it can be used to append remote saves to a local
38 branch, which by extension supports merging repositories. See
39 `bup-get(1)` for further information, and please note, this is a new
40 *EXPERIMENTAL* command that can (intentionally) modify your data in
41 destructive ways. It is potentially much more dangerous than most
42 `bup` commands. Treat with caution.
44 * `bup` can now restore directly from a remote repository via `bup
45 restore -r host:path ...`. See `bup-restore(1)` for more
48 * `bup ls` can now report information for remote repositories via `bup
49 ls -r host:path ...`. See `bup-ls(1)` for more information.
51 * `bup` should respect the git pack.packSizeLimit setting when writing
52 packfiles, though at the moment it will only affect a remote
53 repository when the option is set there directly.
55 * `bup save` now stores the size for all links and normal files. For
56 directories saved using this new format retrieving file sizes for
57 larger files should be notably less expensive. Among other things
58 this may improve the performance of commands like `bup ls -l` or
59 `find /some/fuse/dir -ls`.
61 * The VFS (Virtual File System) that underlies many operations, and
62 provides the basis for commands like `restore`, `ls`, etc. has been
63 rewritten in a way that makes remote repository access easier,
64 should decrease the memory footprint in some cases (e.g. for bup
65 fuse), and should make it easier to provide more selective caching.
66 At the moment, data is just evicted at random once a threshold is
69 * A `--noop <--blobs|--tree>` option has been added to `bup split`
70 which prints the resulting id without storing the data in the
76 * The way `bup` handles output from subprocesses (diagnostics,
77 progress, etc.) has been adjusted in a way that should make it less
78 likely that bup might continue running after the main process has
79 exited, say via a C-c (SIGINT).
81 * `bup` should now respect the specified compression level when
82 writing to a remote repository.
84 * `bup restore` now creates FIFOs with mkfifo, not mknod, which is
85 more portable. The previous approach did not work correctly on (at
86 least) some versions of NetBSD.
88 * `bup` should no longer just crash when it encounters a commit with a
89 "mergetag" header. For the moment, it just ignores them, and
90 they'll be discarded whenever `bup` rewrites a commit, say via the
91 `rm`, `prune-older`, or `get` commands.
93 * The bloom command should now end progress messages with \r, not \n,
94 which avoids leaving spurious output lines behind at exit.
96 * A missing space has been added to the `bup split --bench` output.
98 * Various Python version compatibility problems have been fixed,
99 including some of the incompatibilities introduced by Python 3.
101 * Some issues with mincore on WSL have been fixed.
103 * Some Android build incompatibilities have been fixed.
109 * The tests no longer assume pwd is in /bin.
111 * The tests should be less sensitive to the locale.
113 * `test-meta` should no longer try to apply chattr +T to files. 'T'
114 only works for directories, and newer Linux kernels actually reject
115 the attempt (as of at least 4.12, and maybe 4.10).
117 * `test-rm` should no longer fail when newer versions of git
118 automatically create packed-refs.
120 * `test-sparse-files` should be less likely to fail when run inside a
123 * `test-index-check-device` and `test-xdev` now use separate files for
124 their loopback mounts. Previously each was mounting the same image
125 twice, which could produce the same device number.
