4003 # This is the replacement for the rev_db format, which was too big
4004 # and inefficient for large repositories with a lot of sparse history
4007 # The format is this:
4008 # - 24 bytes for every record,
4009 # * 4 bytes for the integer representing an SVN revision number
4010 # * 20 bytes representing the sha1 of a git commit
4011 # - No empty padding records like the old format
4012 # (except the last record, which can be overwritten)
4013 # - new records are written append-only since SVN revision numbers
4014 # increase monotonically
4015 # - lookups on SVN revision number are done via a binary search
4016 # - Piping the file to xxd -c24 is a good way of dumping it for
4017 # viewing or editing (piped back through xxd -r), should the need
4019 # - The last record can be padding revision with an all-zero sha1
