1git-repack(1) 2============= 3 4NAME 5---- 6git-repack - Pack unpacked objects in a repository 7 8 9SYNOPSIS 10-------- 11'git-repack' [-a] [-d] [-f] [-l] [-n] [-q] [--window=N] [--depth=N] 12 13DESCRIPTION 14----------- 15 16This script is used to combine all objects that do not currently 17reside in a "pack", into a pack. 18 19A pack is a collection of objects, individually compressed, with 20delta compression applied, stored in a single file, with an 21associated index file. 22 23Packs are used to reduce the load on mirror systems, backup 24engines, disk storage, etc. 25 26OPTIONS 27------- 28 29-a:: 30 Instead of incrementally packing the unpacked objects, 31 pack everything available into a single pack. 32 Especially useful when packing a repository that is used 33 for private development and there is no need to worry 34 about people fetching via dumb file transfer protocols 35 from it. Use with '-d'. 36 37-d:: 38 After packing, if the newly created packs make some 39 existing packs redundant, remove the redundant packs. 40 Also runs gitlink:git-prune-packed[1]. 41 42-l:: 43 Pass the `--local` option to `git pack-objects`, see 44 gitlink:git-pack-objects[1]. 45 46-f:: 47 Pass the `--no-reuse-delta` option to `git pack-objects`, see 48 gitlink:git-pack-objects[1]. 49 50-q:: 51 Pass the `-q` option to `git pack-objects`, see 52 gitlink:git-pack-objects[1]. 53 54-n:: 55 Do not update the server information with 56 `git update-server-info`. 57 58--window=[N], --depth=[N]:: 59 These two options affect how the objects contained in the pack are 60 stored using delta compression. The objects are first internally 61 sorted by type, size and optionally names and compared against the 62 other objects within `--window` to see if using delta compression saves 63 space. `--depth` limits the maximum delta depth; making it too deep 64 affects the performance on the unpacker side, because delta data needs 65 to be applied that many times to get to the necessary object. 66 The default value for --window is 10 and --depth is 50. 67 68--max-pack-size=<n>:: 69 Maximum size of each output packfile, expressed in MiB. 70 If specified, multiple packfiles may be created. 71 The default is unlimited. 72 73 74Configuration 75------------- 76 77When configuration variable `repack.UseDeltaBaseOffset` is set 78for the repository, the command passes `--delta-base-offset` 79option to `git-pack-objects`; this typically results in slightly 80smaller packs, but the generated packs are incompatible with 81versions of git older than (and including) v1.4.3; do not set 82the variable in a repository that older version of git needs to 83be able to read (this includes repositories from which packs can 84be copied out over http or rsync, and people who obtained packs 85that way can try to use older git with it). 86 87 88Author 89------ 90Written by Linus Torvalds <torvalds@osdl.org> 91 92Documentation 93-------------- 94Documentation by Ryan Anderson <ryan@michonline.com> 95 96See Also 97-------- 98gitlink:git-pack-objects[1] 99gitlink:git-prune-packed[1] 100 101GIT 102--- 103Part of the gitlink:git[7] suite 104
