The index-pack documentation explicitly states that the pack name is derived from the sorted list of object names, but since commit1190a1acf8
("pack-objects: name pack files after trailer hash") that isn't true anymore. Be less explicit in the docs as to what the exact output is, and just say that it's whatever goes into the pack name. Also update a comment on write_idx_file() since it no longer modifies the sha1 variable (it's const now anyway), as noted by Junio. Fixes:1190a1acf8

NAME
|
|
----
|
|
git-index-pack - Build pack index file for an existing packed archive
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git index-pack' [-v] [-o <index-file>] <pack-file>
|
|
'git index-pack' --stdin [--fix-thin] [--keep] [-v] [-o <index-file>]
|
|
[<pack-file>]
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
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.
|
|
|
|
|
|
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).
|
|
|
|
--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.
|
|
|
|
--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.
|
|
|
|
|
|
Note
|
|
----
|
|
|
|
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.
