-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).
--[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. However, instead of 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[=<msg-id>=<severity>...]
Die, if the pack contains broken objects or links. An
optional comma-separated list of
<msg-id>=<severity> can be
passed to change the severity of some possible issues, e.g.,
--strict="missingEmail=ignore,badTagName=error". See the
entry for the
fsck.<msg-id> configuration options in
git-fsck(1) for more information on the possible values of
<msg-id> and
<severity>.
--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[=<msg-id>=<severity>...]
Die if the pack contains broken objects, but unlike
--strict, don’t choke on broken links. 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").
An optional comma-separated list of
<msg-id>=<severity> can be passed to change the severity
of some possible issues, e.g.,
--fsck-objects="missingEmail=ignore,badTagName=ignore". See
the entry for the fsck.<msg-id> configuration options in
git-fsck(1) for more information on the possible values of
<msg-id> and <severity>.
--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.
Note: At present, there is no interoperability between SHA-256
repositories and SHA-1 repositories.
Historically, we warned that SHA-256 repositories may later need
backward incompatible changes when we introduce such interoperability
features. Today, we only expect compatible changes. Furthermore, if such
changes prove to be necessary, it can be expected that SHA-256 repositories
created with today’s Git will be usable by future versions of Git
without data loss.
--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.
