warning(_("failed to add packfile '%s'"),
The add_pack_to_midx() callback used via for_each_file_in_pack_dir() is used to add packs with .idx files to the MIDX being written. Within this function, we have a pair of checks that discards packs which: - appear in an existing MIDX, if we successfully read an existing MIDX from disk - or, appear in the "to_include" list, if invoking the MIDX write machinery with the `--stdin-packs` command-line argument. In a future commit will want to call a slight variant of these checks from the code that reuses all packs from an existing MIDX, as well as the current location via add_pack_to_midx(). The latter will be modified in subsequent commits to only reuse packs which appear in the to_include list, if one was given. Prepare for that step by extracting these checks as a subroutine that may be called from both places.
