git-multi-pack-index

Use given directory for the location of Git objects. We check <dir>/packs/multi-pack-index for the current MIDX file, and <dir>/packs for the pack-files to index. <dir> must be an alternate of the current repository.

Optionally specify the tie-breaking pack used when multiple packs contain the same object. <pack> must contain at least one object. If not given, ties are broken in favor of the pack with the lowest mtime.

Write a multi-pack index containing only the set of line-delimited pack index basenames provided over stdin.

With --bitmap, optionally specify a file which contains a "refs snapshot" taken prior to repacking. A reference snapshot is composed of line-delimited OIDs corresponding to the reference tips, usually taken by git repack prior to generating a new pack. A line may optionally start with a + character to indicate that the reference which corresponds to that OID is "preferred" (see git-config(1)'s pack.preferBitmapTips.) The file given at <path> is expected to be readable, and can contain duplicates. (If a given OID is given more than once, it is marked as preferred if at least one instance of it

Write an incremental MIDX file containing only objects and packs not present in an existing MIDX layer. Migrates non-incremental MIDXs to incremental ones when necessary. Incompatible with --bitmap.
