3969 | # one of my favorite modules is out :< Next up would be one of the DBM | |
3970 | # modules, but I'm not sure which is most portable... | |
3971 | # | |
3972 | # This is the replacement for the rev_db format, which was too big | |
3973 | # and inefficient for large repositories with a lot of sparse history | |
3974 | # (mainly tags) | |
3975 | # | |
3976 | # The format is this: | |
3977 | # - 24 bytes for every record, | |
3978 | # * 4 bytes for the integer representing an SVN revision number | |
3979 | # * 20 bytes representing the sha1 of a git commit | |
3980 | # - No empty padding records like the old format | |
3981 | # (except the last record, which can be overwritten) | |
3982 | # - new records are written append-only since SVN revision numbers | |
3983 | # increase monotonically | |
3984 | # - lookups on SVN revision number are done via a binary search | |
3985 | # - Piping the file to xxd -c24 is a good way of dumping it for | |
3986 | # viewing or editing (piped back through xxd -r), should the need | |
3987 | # ever arise. | |
3988 | # - The last record can be padding revision with an all-zero sha1 | |
3989 | # This is used to optimize fetch performance when using multiple | |
3990 | # "fetch" directives in .git/config | |
3991 | # | |
3992 | # These files are disposable unless noMetadata or useSvmProps is set | |
