It handles all three configuration mechanisms historically +and currently used by git, and presents the information in a uniform +fashion. Note that the code also handles plain URLs without any +configuration, giving them just the default information. + +struct remote +------------- + +`name`:: + + The user's nickname for the remote + +`url`:: + + An array of all of the url_nr URLs configured for the remote + +`push`:: + + An array of refspecs configured for pushing, with + push_refspec being the literal strings, and push_refspec_nr + being the quantity. + +`fetch`:: + + An array of refspecs configured for fetching, with + fetch_refspec being the literal strings, and fetch_refspec_nr + being the quantity. + +`fetch_tags`:: + + The setting for whether to fetch tags (as a separate rule from + the configured refspecs); -1 means never to fetch tags, 0 + means to auto-follow tags based on the default heuristic, 1 + means to always auto-follow tags, and 2 means to fetch all + tags. + +`receivepack`, `uploadpack`:: + + The configured helper programs to run on the remote side, for + git-native protocols. + +`http_proxy`:: + + The proxy to use for curl (http, https, ftp, etc.) URLs. + +struct remotes can be found by name with remote_get(), and iterated +through with for_each_remote(). remote_get(NULL) will return the +default remote, given the current branch and configuration. + +struct refspec +-------------- + +A struct refspec holds the parsed interpretation of a refspec. If it +will force updates (starts with a '+'), force is true. If it is a +pattern (sides end with '*') pattern is true. src and dest are the two +sides (if a pattern, only the part outside of the wildcards); if there +is only one side, it is src, and dst is NULL; if sides exist but are +empty (i.e., the refspec either starts or ends with ':'), the +corresponding side is "". + +This parsing can be done to an array of strings to give an array of +struct refpsecs with parse_ref_spec(). + +remote_find_tracking(), given a remote and a struct refspec with +either src or dst filled out, will fill out the other such that the +result is in the "fetch" specification for the remote (note that this +evaluates patterns and returns a single result). + +struct branch +------------- + +Note that this may end up moving to branch.h + +struct branch holds the configuration for a branch. It can be looked +up with branch_get(name) for "refs/heads/{name}", or with +branch_get(NULL) for HEAD. + +It contains: + +`name`:: + + The short name of the branch. + +`refname`:: + + The full path for the branch ref. + +`remote_name`:: + + The name of the remote listed in the configuration. + +`remote`:: + + The struct remote for that remote. + +`merge_name`:: + + An array of the "merge" lines in the configuration. + +`merge`:: + + An array of the struct refspecs used for the merge lines. That + is, merge[i]->dst is a local tracking ref which should be + merged into this branch by default. + +`merge_nr`:: + + The number of merge configurations + +branch_has_merge_config() returns true if the given branch has merge +configuration given. + +Other stuff +----------- + +There is other stuff in remote.h that is related, in general, to the +process of interacting with remotes. + +(Daniel Barkalow) -- cgit v1.2.3
