1git-index-pack(1) 2================= 3 4NAME 5---- 6git-index-pack - Build pack index file for an existing packed archive 7 8 9SYNOPSIS 10-------- 11'git-index-pack' [-v] [-o <index-file>] <pack-file> 12'git-index-pack' --stdin [--fix-thin] [--keep] [-v] [-o <index-file>] [<pack-file>] 13 14 15DESCRIPTION 16----------- 17Reads a packed archive (.pack) from the specified file, and 18builds a pack index file (.idx) for it. The packed archive 19together with the pack index can then be placed in the 20objects/pack/ directory of a git repository. 21 22 23OPTIONS 24------- 25-v:: 26 Be verbose about what is going on, including progress status. 27 28-o <index-file>:: 29 Write the generated pack index into the specified 30 file. Without this option the name of pack index 31 file is constructed from the name of packed archive 32 file by replacing .pack with .idx (and the program 33 fails if the name of packed archive does not end 34 with .pack). 35 36--stdin:: 37 When this flag is provided, the pack is read from stdin 38 instead and a copy is then written to <pack-file>. If 39 <pack-file> is not specified, the pack is written to 40 objects/pack/ directory of the current git repository with 41 a default name determined from the pack content. If 42 <pack-file> is not specified consider using --keep to 43 prevent a race condition between this process and 44 gitlink::git-repack[1] . 45 46--fix-thin:: 47 It is possible for gitlink:git-pack-objects[1] to build 48 "thin" pack, which records objects in deltified form based on 49 objects not included in the pack to reduce network traffic. 50 Those objects are expected to be present on the receiving end 51 and they must be included in the pack for that pack to be self 52 contained and indexable. Without this option any attempt to 53 index a thin pack will fail. This option only makes sense in 54 conjunction with --stdin. 55 56--keep:: 57 Before moving the index into its final destination 58 create an empty .keep file for the associated pack file. 59 This option is usually necessary with --stdin to prevent a 60 simultaneous gitlink:git-repack[1] process from deleting 61 the newly constructed pack and index before refs can be 62 updated to use objects contained in the pack. 63 64--keep='why':: 65 Like --keep create a .keep file before moving the index into 66 its final destination, but rather than creating an empty file 67 place 'why' followed by an LF into the .keep file. The 'why' 68 message can later be searched for within all .keep files to 69 locate any which have outlived their usefulness. 70 71 72Note 73---- 74 75Once the index has been created, the list of object names is sorted 76and the SHA1 hash of that list is printed to stdout. If --stdin was 77also used then this is prefixed by either "pack\t", or "keep\t" if a 78new .keep file was successfully created. This is useful to remove a 79.keep file used as a lock to prevent the race with gitlink:git-repack[1] 80mentioned above. 81 82 83Author 84------ 85Written by Sergey Vlasov <vsu@altlinux.ru> 86 87Documentation 88------------- 89Documentation by Sergey Vlasov 90 91GIT 92--- 93Part of the gitlink:git[7] suite 94
