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 + gitlink::git-repack[1] . + +--fix-thin:: + It is possible for gitlink:git-pack-objects[1] to build + "thin" pack, which records objects in deltified form based on + objects not included in the pack to reduce network traffic. + Those objects are expected to be present on the receiving end + and they must be included in the pack for that pack to be self + contained and indexable. Without this option any attempt to + index a thin pack will fail. 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 gitlink:git-repack[1] process from deleting + the newly constructed pack and index before refs can be + updated to use objects contained in the pack. + +--keep='why':: + Like --keep create a .keep file before moving the index into + its final destination, but rather than creating an empty file + place 'why' followed by an LF into the .keep file. The 'why' + 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. + + +Note +---- + +Once the index has been created, the list of object names is sorted +and the SHA1 hash of that list 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 gitlink:git-repack[1] +mentioned above. + + +Author +------ +Written by Sergey Vlasov <vsu@altlinux.ru> + +Documentation +------------- +Documentation by Sergey Vlasov + +GIT +--- +Part of the gitlink:git[7] suite + |
