| 215a7ad1 | 6 | git-repack - Script used to pack a repository from a collection of |
| e31bb3bb JH |
7 | objects into pack files. |

| 14 | DESCRIPTION | |

17 | This script is used to combine all objects that do not currently |
| 18 | reside in a "pack", into a pack. | |
| 19 | ||
| 20 | A pack is a collection of objects, individually compressed, with | |
| 21 | delta compression applied, stored in a single file, with an | |
| 22 | associated index file. | |
| 23 | ||
| 24 | Packs are used to reduce the load on mirror systems, backup | |
| 25 | engines, disk storage, etc. | |
| 26 | ||
| 27 | OPTIONS | |
| 28 | ------- | |
| 29 | ||
| 30 | -a:: | |
| 31 | Instead of incrementally packing the unpacked objects, | |
| 32 | pack everything available into a single pack. | |
| 33 | Especially useful when packing a repository that is used | |
| 34 | for a private development and there no need to worry | |
| 35 | about people fetching via dumb protocols from it. Use | |
| 36 | with '-d'. | |
| 37 | ||
| 38 | -d:: | |
| 39 | After packing, if the newly created packs make some | |
| 40 | existing packs redundant, remove the redundant packs. | |
| 2b5f3ed3 | 41 | Also runs gitlink:git-prune-packed[1]. |

43 | -l:: |
| 44 | Pass the `--local` option to `git pack-objects`, see | |
| 45 | gitlink:git-pack-objects[1]. | |

| cec2be76 JH |
47 | -f:: |
| 48 | Pass the `--no-reuse-delta` option to `git pack-objects`, see | |
| 49 | gitlink:git-pack-objects[1]. | |
| 50 | ||
| 51 | -q:: | |
| 52 | Pass the `-q` option to `git pack-objects`, see | |
| 53 | gitlink:git-pack-objects[1]. | |
| 54 | ||
| 31f23281 NW |
55 | -n:: |
| 56 | Do not update the server information with | |
| 57 | `git update-server-info`. | |
| e31bb3bb | 58 | |
| 02ac04fc | 59 | --window=[N], --depth=[N]:: |
| 3df19671 | 60 | These two options affect how the objects contained in the pack are |
| 02ac04fc JF |
61 | stored using delta compression. The objects are first internally |
| 62 | sorted by type, size and optionally names and compared against the | |
| 63 | other objects within `--window` to see if using delta compression saves | |
| 64 | space. `--depth` limits the maximum delta depth; making it too deep | |
| 65 | affects the performance on the unpacker side, because delta data needs | |
| 66 | to be applied that many times to get to the necessary object. | |
| 3df19671 | 67 | The default value for both --window and --depth is 10. |
