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 both --window and --depth is 10. + + +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). + + +Author +------ +Written by Linus Torvalds <torvalds@osdl.org> + +Documentation +-------------- +Documentation by Ryan Anderson <ryan@michonline.com> + +See Also +-------- +gitlink:git-pack-objects[1] +gitlink:git-prune-packed[1] + +GIT +--- +Part of the gitlink:git[7] suite + |
