3085 | # one of my favorite modules is out :< Next up would be one of the DBM | |
3086 | # modules, but I'm not sure which is most portable... | |
3087 | # | |
3088 | # This is the replacement for the rev_db format, which was too big | |
3089 | # and inefficient for large repositories with a lot of sparse history | |
3090 | # (mainly tags) | |
3091 | # | |
3092 | # The format is this: | |
3093 | # - 24 bytes for every record, | |
3094 | # * 4 bytes for the integer representing an SVN revision number | |
3095 | # * 20 bytes representing the sha1 of a git commit | |
3096 | # - No empty padding records like the old format | |
3097 | # (except the last record, which can be overwritten) | |
3098 | # - new records are written append-only since SVN revision numbers | |
3099 | # increase monotonically | |
3100 | # - lookups on SVN revision number are done via a binary search | |
3101 | # - Piping the file to xxd -c24 is a good way of dumping it for | |
3102 | # viewing or editing (piped back through xxd -r), should the need | |
3103 | # ever arise. | |
3104 | # - The last record can be padding revision with an all-zero sha1 | |
3105 | # This is used to optimize fetch performance when using multiple | |
3106 | # "fetch" directives in .git/config | |
3107 | # | |
3108 | # These files are disposable unless noMetadata or useSvmProps is set | |
