1git-commit-graph(1) 2=================== 3 4NAME 5---- 6git-commit-graph - Write and verify Git commit graph files 7 8 9SYNOPSIS 10-------- 11[verse] 12'git commit-graph read' [--object-dir <dir>] 13'git commit-graph verify' [--object-dir <dir>] 14'git commit-graph write' <options> [--object-dir <dir>] 15 16 17DESCRIPTION 18----------- 19 20Manage the serialized commit graph file. 21 22 23OPTIONS 24------- 25--object-dir:: 26 Use given directory for the location of packfiles and commit graph 27 file. This parameter exists to specify the location of an alternate 28 that only has the objects directory, not a full `.git` directory. The 29 commit graph file is expected to be at `<dir>/info/commit-graph` and 30 the packfiles are expected to be in `<dir>/pack`. 31 32 33COMMANDS 34-------- 35'write':: 36 37Write a commit graph file based on the commits found in packfiles. 38+ 39With the `--stdin-packs` option, generate the new commit graph by 40walking objects only in the specified pack-indexes. (Cannot be combined 41with `--stdin-commits` or `--reachable`.) 42+ 43With the `--stdin-commits` option, generate the new commit graph by 44walking commits starting at the commits specified in stdin as a list 45of OIDs in hex, one OID per line. (Cannot be combined with 46`--stdin-packs` or `--reachable`.) 47+ 48With the `--reachable` option, generate the new commit graph by walking 49commits starting at all refs. (Cannot be combined with `--stdin-commits` 50or `--stdin-packs`.) 51+ 52With the `--append` option, include all commits that are present in the 53existing commit-graph file. 54 55'read':: 56 57Read the commit-graph file and output basic details about it. 58Used for debugging purposes. 59 60'verify':: 61 62Read the commit-graph file and verify its contents against the object 63database. Used to check for corrupted data. 64 65 66EXAMPLES 67-------- 68 69* Write a commit graph file for the packed commits in your local `.git` 70 directory. 71+ 72------------------------------------------------ 73$ git commit-graph write 74------------------------------------------------ 75 76* Write a commit-graph file, extending the current commit-graph file 77 using commits in `<pack-index>`. 78+ 79------------------------------------------------ 80$ echo <pack-index> | git commit-graph write --stdin-packs 81------------------------------------------------ 82 83* Write a commit-graph file containing all reachable commits. 84+ 85------------------------------------------------ 86$ git show-ref -s | git commit-graph write --stdin-commits 87------------------------------------------------ 88 89* Write a commit-graph file containing all commits in the current 90 commit-graph file along with those reachable from `HEAD`. 91+ 92------------------------------------------------ 93$ git rev-parse HEAD | git commit-graph write --stdin-commits --append 94------------------------------------------------ 95 96* Read basic information from the commit-graph file. 97+ 98------------------------------------------------ 99$ git commit-graph read 100------------------------------------------------ 101 102 103GIT 104--- 105Part of the linkgit:git[1] suite
