    doc/import-rsnapshot: small corrections and clarification

    lelutin committed with
    There's a typo in the --dry-run option explanation.
    The form "[...] or only imports all [...]" is confusing. Turn it around
    a little bit so that the quantifiers are associated more easily to the
    right portions of the sentence.
    Also, add an example for using the backuptarget argument.

  1. cmd/midx, all else being equal, delete older midxes first.

    Previous runs of 'bup midx -f' might have created invalid midx files with
    exactly the same length as a newer run.  bup's "prune redundant midx" logic
    would quasi-randomly choose one or the other to delete (based on
    alphabetical order of filenames, basically) and sometimes that would be the
    new one, not the old one, so the 'bup midx -f' results never actually kicked
    Now if the file sizes are equal we'll use the mtime as a tie breaker; newer
    is better.

  2. t/ a test for the recently-uncovered midx4 problem.

    Signed-off-by: Avery Pennarun <>
  3. _helpers.c: midx4 didn't handle multiple index with the same object.

    It *tried* to handle it, but would end up with a bunch of zero entries at
    the end, which prevents .exists() from working correctly in some cases.
    In midx2, it made sense to never include the same entry twice, because the
    only informatin we had about a particular entry was that it existed.  In
    midx4 this is no longer true; we might sometimes want to know *all* the idx
    files that contain a particular object (for example, when we implement
    expiry later).  So the easiest fix for this bug is to just include multiple
    entries when we have them.

  4. cmd/midx: add a --check option.

    Running this on my system does reveal that some objects return
    exists()==False on my midx even though they show up during iteration.
    Now to actually find and fix it...

  5. Add git.shorten_hash(), printing only the first few bytes of a sha1.

    The full name is rarely needed and clutters the output.  Let's try this
    instead in a few places.

  6. add some additional tests that objcache.refresh() is called.

    somehow though.

    This generally improves our test coverage of bloom filter behavior and

  7. move bloom.ShaBloom.create to just bloom.create.

    I don't really like class-level functions.  Ideally we'd just move all the
    creation stuff into cmd/bloom, but is testing them, so it's not
    really worth it.

  8. Merge branch 'bl/bloomcheck' into ap/cleanups

    * bl/bloomcheck:
      Bail out immediately instead of redownloading .idx
      Add a --check behavior to verify bloom
      Defines/preprocessor lengths > magic numbers
  9. Move bloom-related stuff from to a new

    No other functionality changes other than that cmd/memtest now reports the
    number of bloom steps separately from the midx/idx steps.  (This is mostly
    so they don't have to share the same global variables, but it's also
    interesting information to break out.)

  10. cmd/bloom: add a --force option to forget regenerating the bloom.

    This corresponds to midx's --force option.

  11. Use the new qprogress() function in more places.

    qprogress() was introduced in the last commit and has smarter default
    behaviour that automatically reduces progress output so we don't print too
    many messages per second.  Various commands/etc were doing this in various
    different ad-hoc ways, but let's centralize it all in one place.

  12. Bail out immediately instead of redownloading .idx

    Brandon Low committed with
    This should make diagnosing / fixing corrupted bloom filters and midx
    files easier, and is generally more sane behavior.

  13. Add a --check behavior to verify bloom

    Brandon Low committed with
    This new behavior is useful when diagnosing weird behavior, lets a bloom
    filter claiming to contain a particular idx be verified against that idx

  14. Defines/preprocessor lengths > magic numbers

    Brandon Low committed with
    This just changes some instances of "8", "12" and "20" to use the
    equivalent sizeof or #defined constants to make the code more readable.

  15. cmd/{bloom,midx}: clean up progress messages.

    bloom was printing messages more often than necessary on fast computers,
    which could overwhelm the stderr output a bit.  Also change to a percentage
    + number of objects, like midx and save do, rather than just printing the
    current file number.
    And don't print so many lines of output by default: now if bloom isn't
    end up doing anything, it doesn't print any output.  And if it does do
    something, it prints only one output line per file.
    bloom and midx now both print the name of the directory where they're
    creating their output files; if you have multiple directories in
    .bup/index-cache, it was a little confusing to see them doing
    multiple runs for no apparent reason.

  16. cmd/bloom: by default generate bloom filters in *all* index-cache dirs.

    This matches with 'bup midx -a' and 'bup midx -f' behaviour.  People might
    have been thinking they were regenerating bloom filters without actually
    doing them all.
    Moved some shared code to do this from cmd/midx to

    …n \r.
    If the last output was a progress message, we would blank out the line
    (which was correct) but then we'd print a newline, which was wrong.  Only

  2. cmd/index: make the default mode '-u'.

    I always forget the -u option, and it's by far the most common thing to do
    with 'bup index'.  So if no mode option is provided, just default to that

    Py_GetArgcArgv() doesn't exist on win32 platforms.  Which isn't so bad,

    This was a remaining CPU bottleneck in bup-dumb-server mode.  In a quick

  2. cmd/daemon: FD_CLOEXEC the listener socket and don't leak fd for the …

    Otherwise the listener gets inherited by all the child processes (mostly
    harmless) and subprograms run by bup-server inherit an extra fd for the
    connection socket (problematic since we want the connection to close as soon
    as bup-server closes).

  3. cmd/daemon: close file descriptors correctly in parent process.

    The client wasn't getting disconnected when the server died, because the
    daemon was still hanging on to its copy of the original socket, due to some
    misplaced os.dup() calls.

    Otherwise we can't re-listen on that socket until the TIME_WAIT period ends,

  5. cmd/daemon: pass extra options along to 'bup server'.

    Currently 'bup server' doesn't take any options, but that might change
    Also use a '--' to separate the bup mux command from its arguments, so it
    doesn't accidentally try to parse them.  This didn't matter before (since
    none of the options we were passing along started with a dash) but if the
    user provides extra options, it might matter.
