| 9 | SYNOPSIS | |
| 10 | -------- | |
| 11 | [verse] | |
| 81efa161 | 12 | 'git multi-pack-index' [--object-dir=<dir>] <subcommand> |
| 6a257f03 DS |
13 | |
| 14 | DESCRIPTION | |
| 15 | ----------- | |
| 16 | Write or verify a multi-pack-index (MIDX) file. | |
| 17 | ||
| 18 | OPTIONS | |
| 19 | ------- | |
| 20 | ||
| 21 | --object-dir=<dir>:: | |
| 22 | Use given directory for the location of Git objects. We check | |
| 23 | `<dir>/packs/multi-pack-index` for the current MIDX file, and | |
| 24 | `<dir>/packs` for the pack-files to index. | |
| 25 | ||

26 | The following subcommands are available: |
| 27 | ||
| a3407730 | 28 | write:: |
| 81efa161 | 29 | Write a new MIDX file. |
| a3407730 | 30 | |
| 56ee7ff1 | 31 | verify:: |
| 81efa161 | 32 | Verify the contents of the MIDX file. |

| cff97116 DS |
34 | expire:: |
| 35 | Delete the pack-files that are tracked by the MIDX file, but | |
| 36 | have no objects referenced by the MIDX. Rewrite the MIDX file | |
| 37 | afterward to remove all references to these pack-files. | |
| 38 | ||
| 2af890bb DS |
39 | repack:: |
| 40 | Create a new pack-file containing objects in small pack-files | |
| 41 | referenced by the multi-pack-index. If the size given by the | |
| 42 | `--batch-size=<size>` argument is zero, then create a pack | |
| 43 | containing all objects referenced by the multi-pack-index. For | |
| 44 | a non-zero batch size, Select the pack-files by examining packs | |
| 45 | from oldest-to-newest, computing the "expected size" by counting | |
| 46 | the number of objects in the pack referenced by the | |
| 47 | multi-pack-index, then divide by the total number of objects in | |
| 48 | the pack and multiply by the pack size. We select packs with | |
| 49 | expected size below the batch size until the set of packs have | |
| 50 | total expected size at least the batch size. If the total size | |
| 51 | does not reach the batch size, then do nothing. If a new pack- | |
| 52 | file is created, rewrite the multi-pack-index to reference the | |
| 53 | new pack-file. A later run of 'git multi-pack-index expire' will | |
| 54 | delete the pack-files that were part of this batch. | |
