| NAME |
| ---- |
| git-repack - Pack unpacked objects in a repository |
| |
| |
| SYNOPSIS |
| -------- |
| 'git-repack' [-a] [-d] [-f] [-l] [-n] [-q] [--window=N] [--depth=N] |
| |
| DESCRIPTION |
| ----------- |
| |
| This script is used to combine all objects that do not currently |
| reside in a "pack", into a pack. |
| |
| A pack is a collection of objects, individually compressed, with |
| delta compression applied, stored in a single file, with an |
| associated index file. |
| |
| Packs are used to reduce the load on mirror systems, backup |
| engines, disk storage, etc. |
| |
| OPTIONS |
| ------- |
| |
| -a:: |
| Instead of incrementally packing the unpacked objects, |
| pack everything available into a single pack. |
| Especially useful when packing a repository that is used |
| for private development and there is no need to worry |
| about people fetching via dumb file transfer protocols |
| from it. Use with '-d'. |
| |
| -d:: |
| After packing, if the newly created packs make some |
| existing packs redundant, remove the redundant packs. |
| Also runs gitlink:git-prune-packed[1]. |
| |
| -l:: |
| Pass the `--local` option to `git pack-objects`, see |
| gitlink:git-pack-objects[1]. |
| |
| -f:: |
| Pass the `--no-reuse-delta` option to `git pack-objects`, see |
| gitlink:git-pack-objects[1]. |
| |
| -q:: |
| Pass the `-q` option to `git pack-objects`, see |
| gitlink:git-pack-objects[1]. |
| |
| -n:: |
| Do not update the server information with |
| `git update-server-info`. |
| |
| --window=[N], --depth=[N]:: |
| These two options affect how the objects contained in the pack are |
| stored using delta compression. The objects are first internally |
| sorted by type, size and optionally names and compared against the |
| other objects within `--window` to see if using delta compression saves |
| space. `--depth` limits the maximum delta depth; making it too deep |
| affects the performance on the unpacker side, because delta data needs |
| to be applied that many times to get to the necessary object. |
| The default value for --window is 10 and --depth is 50. |
| |
| |
| Configuration |
| ------------- |
| |
| When configuration variable `repack.UseDeltaBaseOffset` is set |
| for the repository, the command passes `--delta-base-offset` |
| option to `git-pack-objects`; this typically results in slightly |
| smaller packs, but the generated packs are incompatible with |
| versions of git older than (and including) v1.4.3; do not set |
| the variable in a repository that older version of git needs to |
| be able to read (this includes repositories from which packs can |
| be copied out over http or rsync, and people who obtained packs |
| that way can try to use older git with it). |
