| # rev_map: |
| # Tie::File seems to be prone to offset errors if revisions get sparse, |
| # it's not that fast, either. Tie::File is also not in Perl 5.6. So |
| # one of my favorite modules is out :< Next up would be one of the DBM |
| # modules, but I'm not sure which is most portable... |
| # |
| # This is the replacement for the rev_db format, which was too big |
| # and inefficient for large repositories with a lot of sparse history |
| # (mainly tags) |
| # |
| # The format is this: |
| # - 24 bytes for every record, |
| # * 4 bytes for the integer representing an SVN revision number |
| # * 20 bytes representing the sha1 of a git commit |
| # - No empty padding records like the old format |
| # (except the last record, which can be overwritten) |
| # - new records are written append-only since SVN revision numbers |
| # increase monotonically |
| # - lookups on SVN revision number are done via a binary search |
| # - Piping the file to xxd -c24 is a good way of dumping it for |
| # viewing or editing (piped back through xxd -r), should the need |
| # ever arise. |
| # - The last record can be padding revision with an all-zero sha1 |
| # This is used to optimize fetch performance when using multiple |
| # "fetch" directives in .git/config |
| # |
| # These files are disposable unless noMetadata or useSvmProps is set |
