3576 # This is the replacement for the rev_db format, which was too big
3577 # and inefficient for large repositories with a lot of sparse history
3580 # The format is this:
3581 # - 24 bytes for every record,
3582 # * 4 bytes for the integer representing an SVN revision number
3583 # * 20 bytes representing the sha1 of a git commit
3584 # - No empty padding records like the old format
3585 # (except the last record, which can be overwritten)
3586 # - new records are written append-only since SVN revision numbers
3587 # increase monotonically
3588 # - lookups on SVN revision number are done via a binary search
3589 # - Piping the file to xxd -c24 is a good way of dumping it for
3590 # viewing or editing (piped back through xxd -r), should the need
3592 # - The last record can be padding revision with an all-zero sha1
