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).
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
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 a "thin" pack produced by git
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.
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.
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.
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.
Die, if the pack contains broken objects or links.
Die if the pack contains broken links. For internal use
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").
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.
Die, if the pack is larger than <size>.
Specify the given object format (hash algorithm) for the
pack. The valid values are sha1
and (if enabled) sha256
default is the algorithm for the current repository (set by
), or sha1
if no value is set or outside
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.
