Function prePushRefs

commands/command_pre_push.go:74–96

prePushRefs parses commit information that the pre-push git hook receives: Each line describes a proposed update of the remote ref at the remote sha to the local sha. Multiple updates can be received on multiple lines (such as from 'git push --a

(r io.Reader)

// the local sha. Multiple updates can be received on multiple lines (such as
// from 'git push --all'). These updates are typically received over STDIN.
func prePushRefs(r io.Reader) []*git.RefUpdate {
	scanner := bufio.NewScanner(r)
	refs := make([]*git.RefUpdate, 0, 1)

	// We can be passed multiple lines of refs
	for scanner.Scan() {
		line := strings.TrimSpace(scanner.Text())
		if len(line) == 0 {
			continue
		}

		tracerx.Printf("pre-push: %s", line)

		localRef, remoteRef := decodeRefs(line)
		if git.IsZeroObjectID(localRef.Sha) {
			continue
		}

		refs = append(refs, git.NewRefUpdate(cfg.Git, cfg.PushRemote(), localRef, remoteRef))
	}

	return refs
}

// decodeRefs pulls the sha1s out of the line read from the pre-push
// hook's stdin.
