The --promisor option of 'git index-pack' was created in 88e2f9e
(introduce fetch-object: fetch one promisor object, 2017-12-05) but was
untested. It is currently unused within the Git codebase, but that will
change in an upcoming change to 'git bundle unbundle' when there is a
filter capability.
For now, add documentation about the option and add a test to ensure it
is working as expected.

NAME
|
|
----
|
|
git-index-pack - Build pack index file for an existing packed archive
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'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
|
|
-------
|
|
-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
|
|
linkgit: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.
|
|

|
|
|
|
--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
|
|
link:technical/partial-clone.html[partial clone] 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.
