[PATCH 0/2] repack: write filtered-out objects as loose objects

["Adithya Chakilam via GitGitGadget" <gitgitgadget@gmail.com>]

Some key-value object stores manage and retrieve Git objects individually.
The existing --filter-to option writes filtered-out objects into packs, so
using it with such stores requires unpacking the resulting packs before
importing the objects.

This series adds --filter-to-loose=dir to git repack, allowing filtered-out
objects to be written directly as loose objects into another object
directory.

With --filter-to-loose, repack streams the filtered pack into
unpack-objects, avoiding that extra step and the intermediate pack file. For
example:

git repack -a --filter=blob=1m --filter-to-loose=/path/to/objects

The destination is treated as a Git object directory.

The first patch adds the option for objects already stored in packs. The
second extends it to include loose objects excluded by the filter, so the
destination also receives those objects. Objects already present in the
destination are not rewritten. With -d, the source copies of those loose
objects are removed after all objects have been written successfully.

  repack: add --filter-to-loose to write filtered-out objects as loose
    objects
  repack: also copy loose objects excluded by --filter-to-loose
