3883 # This is the replacement for the rev_db format, which was too big
3884 # and inefficient for large repositories with a lot of sparse history
3887 # The format is this:
3888 # - 24 bytes for every record,
3889 # * 4 bytes for the integer representing an SVN revision number
3890 # * 20 bytes representing the sha1 of a git commit
3891 # - No empty padding records like the old format
3892 # (except the last record, which can be overwritten)
3893 # - new records are written append-only since SVN revision numbers
3894 # increase monotonically
3895 # - lookups on SVN revision number are done via a binary search
3896 # - Piping the file to xxd -c24 is a good way of dumping it for
3897 # viewing or editing (piped back through xxd -r), should the need
3899 # - The last record can be padding revision with an all-zero sha1
3900 # This is used to optimize fetch performance when using multiple
3901 # "fetch" directives in .git/config
3903 # These files are disposable unless noMetadata or useSvmProps is set
