1git-remote-helpers(1) 2===================== 3 4NAME 5---- 6git-remote-helpers - Helper programs for interoperation with remote git 7 8SYNOPSIS 9-------- 10'git remote-<transport>' <remote> 11 12DESCRIPTION 13----------- 14 15These programs are normally not used directly by end users, but are 16invoked by various git programs that interact with remote repositories 17when the repository they would operate on will be accessed using 18transport code not linked into the main git binary. Various particular 19helper programs will behave as documented here. 20 21COMMANDS 22-------- 23 24Commands are given by the caller on the helper's standard input, one per line. 25 26'capabilities':: 27 Lists the capabilities of the helper, one per line, ending 28 with a blank line. 29 30'list':: 31 Lists the refs, one per line, in the format "<value> <name> 32 [<attr> ...]". The value may be a hex sha1 hash, "@<dest>" for 33 a symref, or "?" to indicate that the helper could not get the 34 value of the ref. A space-separated list of attributes follows 35 the name; unrecognized attributes are ignored. After the 36 complete list, outputs a blank line. 37 38'fetch' <sha1> <name>:: 39 Fetches the given object, writing the necessary objects to the 40 database. Outputs a blank line when the fetch is 41 complete. Only objects which were reported in the ref list 42 with a sha1 may be fetched this way. 43+ 44Supported if the helper has the "fetch" capability. 45 46'import' <name>:: 47 Produces a fast-import stream which imports the current value 48 of the named ref. It may additionally import other refs as 49 needed to construct the history efficiently. 50+ 51Supported if the helper has the "import" capability. 52 53If a fatal error occurs, the program writes the error message to 54stderr and exits. The caller should expect that a suitable error 55message has been printed if the child closes the connection without 56completing a valid response for the current command. 57 58Additional commands may be supported, as may be determined from 59capabilities reported by the helper. 60 61CAPABILITIES 62------------ 63 64'fetch':: 65 This helper supports the 'fetch' command. 66 67'import':: 68 This helper supports the 'import' command. 69 70REF LIST ATTRIBUTES 71------------------- 72 73None are defined yet, but the caller must accept any which are supplied. 74 75Documentation 76------------- 77Documentation by Daniel Barkalow. 78 79GIT 80--- 81Part of the linkgit:git[1] suite
