Different helpers have different +capabilities (limited both by the particular helper and by the +capabilities of the system they connect to), and they report what +capabilities they support. + +These programs can store refs in refs/<system>/*, and arbitrary +information in info/<system>. + +COMMANDS +-------- + +Commands are given by the caller on the helper's standard input, one per line. + +'capabilities':: + Outputs a single line with a list of feature names separated + by spaces. Each of these indicates a supported feature of the + helper, and the caller will only attempt operations that are + supported. + +'list':: + Outputs the names of refs, one per line. These may be + followed, after a single space, by "changed" or "unchanged", + indicating whether the foreign repository has changed from the + state in the ref. If the helper doesn't know, it doesn't have + to provide a value. (In particular, it shouldn't do expensive + operations, such as importing the content, to see whether it + matches.) Other information, not yet supported, may be output + as well, separated by single spaces. + +'import' ref:: + Imports the given ref by outputting it in git-fast-import + format. + +'export' commit ref:: + Sends the given commit to the foreign system, with the + location given by ref, and reimports it by outputting it in + git-fast-import format as the foreign system rendered it. ++ +All parents of commit must either have been created with 'import' or +have been passed to 'export' previously. Depending on the features, +there may be other restrictions on what may be exported. + +FEATURES +-------- + +'export':: + Helper supports exporting commits, at least exporting + non-merge commits whose parents are not the parents of any + other commit exported to the same branch or make in the other + system on the same branch. + +'export-branch':: + Helper supports creating new branches by exporting commits to + them. + +'export-merges':: + Helper supports exporting two-parent merges, where both + parents have already been exported successfully. -- 1.6.4.rc3.138.ga6b98.dirty -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
