| 3561 | # and inefficient for large repositories with a lot of sparse history | |
| 3562 | # (mainly tags) | |
| 3563 | # | |
| 3564 | # The format is this: | |
| 3565 | # - 24 bytes for every record, | |
| 3566 | # * 4 bytes for the integer representing an SVN revision number | |
| 3567 | # * 20 bytes representing the sha1 of a git commit | |
| 3568 | # - No empty padding records like the old format | |
| 66ab84b9 | 3569 | # (except the last record, which can be overwritten) |
| 060610c5 EW |
3570 | # - new records are written append-only since SVN revision numbers |
| 3571 | # increase monotonically | |
| 3572 | # - lookups on SVN revision number are done via a binary search | |
| 66ab84b9 EW |
3573 | # - Piping the file to xxd -c24 is a good way of dumping it for |
| 3574 | # viewing or editing (piped back through xxd -r), should the need | |
| 3575 | # ever arise. | |
| 3576 | # - The last record can be padding revision with an all-zero sha1 | |
