6 git-repack - Pack unpacked objects in a repository
11 'git-repack' [-a] [-d] [-f] [-l] [-n] [-q] [--window=N] [--depth=N]
16 This script is used to combine all objects that do not currently
17 reside in a "pack", into a pack.
19 A pack is a collection of objects, individually compressed, with
20 delta compression applied, stored in a single file, with an
21 associated index file.
23 Packs are used to reduce the load on mirror systems, backup
24 engines, disk storage, etc.
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'.
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].
43 Pass the `--local` option to `git pack-objects`, see
44 gitlink:git-pack-objects[1].
47 Pass the `--no-reuse-delta` option to `git pack-objects`, see
48 gitlink:git-pack-objects[1].
51 Pass the `-q` option to `git pack-objects`, see
52 gitlink:git-pack-objects[1].
55 Do not update the server information with
56 `git update-server-info`.
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.
69 Maximum size of each output packfile, expressed in MiB.
70 If specified, multiple packfiles may be created.
71 The default is unlimited.
77 When configuration variable `repack.UseDeltaBaseOffset` is set
78 for the repository, the command passes `--delta-base-offset`
79 option to `git-pack-objects`; this typically results in slightly
80 smaller packs, but the generated packs are incompatible with
81 versions of git older than (and including) v1.4.3; do not set
82 the variable in a repository that older version of git needs to
83 be able to read (this includes repositories from which packs can
84 be copied out over http or rsync, and people who obtained packs
85 that way can try to use older git with it).
