GIT-INDEX-PACK(1) Git Manual GIT-INDEX-PACK(1)
git-index-pack - Build pack index file for an existing packed archive
git index-pack [-v] [-o <index-file>] <pack-file>
git index-pack --stdin [--fix-thin] [--keep] [-v] [-o <index-file>]
[<pack-file>]
Reads a packed archive (.pack) from the specified file, and builds a
pack index file (.idx) for it. The packed archive together with the
pack index can then be placed in the objects/pack/ directory of a Git
repository.
-v
Be verbose about what is going on, including progress status.
-o <index-file>
Write the generated pack index into the specified file. Without
this option the name of pack index file is constructed from the
name of packed archive file by replacing .pack with .idx (and the
program fails if the name of packed archive does not end with
.pack).
--stdin
When this flag is provided, the pack is read from stdin instead
and a copy is then written to <pack-file>. If <pack-file> is not
specified, the pack is written to objects/pack/ directory of the
current Git repository with a default name determined from the
pack content. If <pack-file> is not specified consider using
--keep to prevent a race condition between this process and git
repack.
--fix-thin
Fix a "thin" pack produced by git pack-objects --thin (see
git-pack-objects(1) for details) by adding the excluded objects
the deltified objects are based on to the pack. This option only
makes sense in conjunction with --stdin.
--keep
Before moving the index into its final destination create an
empty .keep file for the associated pack file. This option is
usually necessary with --stdin to prevent a simultaneous git
repack process from deleting the newly constructed pack and index
before refs can be updated to use objects contained in the pack.
--keep=<msg>
Like --keep create a .keep file before moving the index into its
final destination, but rather than creating an empty file place
<msg> followed by an LF into the .keep file. The <msg> message
can later be searched for within all .keep files to locate any
which have outlived their usefulness.
--index-version=<version>[,<offset>]
This is intended to be used by the test suite only. It allows to
force the version for the generated pack index, and to force
64-bit index entries on objects located above the given offset.
--strict
Die, if the pack contains broken objects or links.
--check-self-contained-and-connected
Die if the pack contains broken links. For internal use only.
--threads=<n>
Specifies the number of threads to spawn when resolving deltas.
This requires that index-pack be compiled with pthreads otherwise
this option is ignored with a warning. This is meant to reduce
packing time on multiprocessor machines. The required amount of
memory for the delta search window is however multiplied by the
number of threads. Specifying 0 will cause Git to auto-detect the
number of CPU’s and use maximum 3 threads.
--max-input-size=<size>
Die, if the pack is larger than <size>.
Once the index has been created, the list of object names is sorted
and the SHA-1 hash of that list is printed to stdout. If --stdin was
also used then this is prefixed by either "pack\t", or "keep\t" if a
new .keep file was successfully created. This is useful to remove a
.keep file used as a lock to prevent the race with git repack
mentioned above.
