2664 | # and inefficient for large repositories with a lot of sparse history | |
2665 | # (mainly tags) | |
2666 | # | |
2667 | # The format is this: | |
2668 | # - 24 bytes for every record, | |
2669 | # * 4 bytes for the integer representing an SVN revision number | |
2670 | # * 20 bytes representing the sha1 of a git commit | |
2671 | # - No empty padding records like the old format | |
66ab84b9 | 2672 | # (except the last record, which can be overwritten) |
060610c5 EW |
2673 | # - new records are written append-only since SVN revision numbers |
2674 | # increase monotonically | |
2675 | # - lookups on SVN revision number are done via a binary search | |
66ab84b9 EW |
2676 | # - Piping the file to xxd -c24 is a good way of dumping it for |
2677 | # viewing or editing (piped back through xxd -r), should the need | |
2678 | # ever arise. | |
2679 | # - The last record can be padding revision with an all-zero sha1 | |

2681 | # "fetch" directives in .git/config | |
