1git-repack(1) 2============= 3 4NAME 5---- 6git-repack - Script used to pack a repository from a collection of 7objects into pack files. 8 9 10SYNOPSIS 11-------- 12'git-repack' [-a] [-d] [-f] [-l] [-n] [-q] [--window=N] [--depth=N] 13 14DESCRIPTION 15----------- 16 17This script is used to combine all objects that do not currently 18reside in a "pack", into a pack. 19 20A pack is a collection of objects, individually compressed, with 21delta compression applied, stored in a single file, with an 22associated index file. 23 24Packs are used to reduce the load on mirror systems, backup 25engines, disk storage, etc. 26 27OPTIONS 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. 41 Also runs gitlink:git-prune-packed[1]. 42 43-l:: 44 Pass the `--local` option to `git pack-objects`, see 45 gitlink:git-pack-objects[1]. 46 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 55-n:: 56 Do not update the server information with 57 `git update-server-info`. 58 59--window=[N], --depth=[N]:: 60 These two options affect how the objects contained in the pack are 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. 67 The default value for both --window and --depth is 10. 68 69 70Configuration 71------------- 72 73When configuration variable `repack.UseDeltaBaseOffset` is set 74for the repository, the command passes `--delta-base-offset` 75option to `git-pack-objects`; this typically results in slightly 76smaller packs, but the generated packs are incompatible with 77versions of git older than (and including) v1.4.3; do not set 78the variable in a repository that older version of git needs to 79be able to read (this includes repositories from which packs can 80be copied out over http or rsync, and people who obtained packs 81that way can try to use older git with it). 82 83 84Author 85------ 86Written by Linus Torvalds <torvalds@osdl.org> 87 88Documentation 89-------------- 90Documentation by Ryan Anderson <ryan@michonline.com> 91 92See Also 93-------- 94gitlink:git-pack-objects[1] 95gitlink:git-prune-packed[1] 96 97GIT 98--- 99Part of the gitlink:git[7] suite 100
