7 bup-bloom - generates, regenerates, updates bloom filters
11 bup bloom [-d dir] [-o outfile] [-k hashes] [-c idxfile]
15 `bup bloom` builds a bloom filter file for a bup repo, if
16 one already exists, it checks it and updates or regenerates
22 : the directory, containing .idx files, to process.
23 defaults to $BUP_DIR/objects/pack
25 -o, --outfile=*outfile*
26 : the file to write the bloom filter to. defaults to
30 : number of hash functions to use only 4 and 5 are valid.
31 defaults to 5 for repositories < 2TiB and 4 otherwise.
32 see comments in git.py for more on this value.
35 : checks the bloom file (counterintuitively outfile)
36 against the specified .idx file, first checks that the
37 bloom filter is claiming to contain the .idx, then
38 checks that it does actually contain all of the objects
39 in the .idx. Does not write anything and ignores the
44 Part of the `bup`(1) suite.
