NAME
git-index-pack - Build pack index file for an existing packed archiveSYNOPSIS
git index-pack [-v] [-o <index-file>] [--[no-]rev-index] <pack-file> git index-pack --stdin [--fix-thin] [--keep] [-v] [-o <index-file>] [--[no-]rev-index] [<pack-file>]
DESCRIPTION
Reads a packed archive (.pack) from the specified file, and builds a pack index file (.idx) for it. Optionally writes a reverse-index (.rev) for the specified pack. The packed archive together with the pack index can then be placed in the objects/pack/ directory of a Git repository.OPTIONS
-vBe 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).
--[no-]rev-index
When this flag is provided, generate a reverse
index (a .rev file) corresponding to the given pack. If --verify
is given, ensure that the existing reverse index is correct. Takes precedence
over pack.writeReverseIndex.
--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.
--progress-title
For internal use only.
Set the title of the progress bar. The title is "Receiving objects" by
default and "Indexing objects" when --stdin is
specified.
--check-self-contained-and-connected
Die if the pack contains broken links. For
internal use only.
--fsck-objects
For internal use only.
Die if the pack contains broken objects. If the pack contains a tree pointing to
a .gitmodules blob that does not exist, prints the hash of that blob (for the
caller to check) after the hash that goes into the name of the pack/idx file
(see "Notes").
--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>.
--object-format=<hash-algorithm>
Specify the given object format (hash
algorithm) for the pack. The valid values are sha1 and (if enabled)
sha256. The default is the algorithm for the current repository (set by
extensions.objectFormat), or sha1 if no value is set or outside
a repository.
This option cannot be used with --stdin.
THIS OPTION IS EXPERIMENTAL! SHA-256 support is experimental and still in an
early stage. A SHA-256 repository will in general not be able to share work
with "regular" SHA-1 repositories. It should be assumed that, e.g.,
Git internal file formats in relation to SHA-256 repositories may change in
backwards-incompatible ways. Only use --object-format=sha256 for
testing purposes.
--promisor[=<message>]
Before committing the pack-index, create a
.promisor file for this pack. Particularly helpful when writing a promisor
pack with --fix-thin since the name of the pack is not final until the pack
has been fully written. If a <message> is provided, then that
content will be written to the .promisor file for future reference. See
partial clone[1] for more information.
NOTES
Once the index has been created, the hash that goes into the name of the pack/idx file 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.GIT
