6 git-index-pack - Build pack index file for an existing packed archive
12 'git index-pack' [-v] [-o <index-file>] <pack-file>
13 'git index-pack' --stdin [--fix-thin] [--keep] [-v] [-o <index-file>]
19 Reads a packed archive (.pack) from the specified file, and
20 builds a pack index file (.idx) for it. The packed archive
21 together with the pack index can then be placed in the
22 objects/pack/ directory of a Git repository.
28 Be verbose about what is going on, including progress status.
31 Write the generated pack index into the specified
32 file. Without this option the name of pack index
33 file is constructed from the name of packed archive
34 file by replacing .pack with .idx (and the program
35 fails if the name of packed archive does not end
39 When this flag is provided, the pack is read from stdin
40 instead and a copy is then written to <pack-file>. If
41 <pack-file> is not specified, the pack is written to
42 objects/pack/ directory of the current Git repository with
43 a default name determined from the pack content. If
44 <pack-file> is not specified consider using --keep to
45 prevent a race condition between this process and
49 Fix a "thin" pack produced by `git pack-objects --thin` (see
50 linkgit:git-pack-objects[1] for details) by adding the
51 excluded objects the deltified objects are based on to the
52 pack. This option only makes sense in conjunction with --stdin.
55 Before moving the index into its final destination
56 create an empty .keep file for the associated pack file.
57 This option is usually necessary with --stdin to prevent a
58 simultaneous 'git repack' process from deleting
59 the newly constructed pack and index before refs can be
60 updated to use objects contained in the pack.
63 Like --keep create a .keep file before moving the index into
64 its final destination, but rather than creating an empty file
65 place '<msg>' followed by an LF into the .keep file. The '<msg>'
66 message can later be searched for within all .keep files to
67 locate any which have outlived their usefulness.
69 --index-version=<version>[,<offset>]::
70 This is intended to be used by the test suite only. It allows
71 to force the version for the generated pack index, and to force
72 64-bit index entries on objects located above the given offset.
75 Die, if the pack contains broken objects or links.
77 --check-self-contained-and-connected::
78 Die if the pack contains broken links. For internal use only.
81 Die if the pack contains broken objects. For internal use only.
84 Specifies the number of threads to spawn when resolving
85 deltas. This requires that index-pack be compiled with
86 pthreads otherwise this option is ignored with a warning.
87 This is meant to reduce packing time on multiprocessor
88 machines. The required amount of memory for the delta search
89 window is however multiplied by the number of threads.
90 Specifying 0 will cause Git to auto-detect the number of CPU's
91 and use maximum 3 threads.
93 --max-input-size=<size>::
94 Die, if the pack is larger than <size>.
96 --object-format=<hash-algorithm>::
97 Specify the given object format (hash algorithm) for the pack. The valid
98 values are 'sha1' and (if enabled) 'sha256'. The default is the algorithm for
99 the current repository (set by `extensions.objectFormat`), or 'sha1' if no
100 value is set or outside a repository.
102 This option cannot be used with --stdin.

109 Once the index has been created, the hash that goes into the name of
110 the pack/idx file is printed to stdout. If --stdin was
111 also used then this is prefixed by either "pack\t", or "keep\t" if a
112 new .keep file was successfully created. This is useful to remove a
113 .keep file used as a lock to prevent the race with 'git repack'
