write_midx_internal() uses a hashfile to write the multi-pack index, but discards its checksum. This makes sense, since nothing that takes place after writing the MIDX cares about its checksum. That is about to change in a subsequent patch, when the optional reverse index corresponding to the MIDX will want to include the MIDX's checksum. Store the checksum of the MIDX in preparation for that. Signed-off-by: Taylor Blau <redacted> --- midx.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
