Functions

func FormatTag 

func FormatTag(
	objectID git.ObjectID,
	objectType string,
	tagName, tagBody []byte,
	committer *gitalypb.User,
	committerDate time.Time,
) (string, error)

FormatTag is used by WriteTag (or for testing) to make the tag signature to feed to git-mktag, i.e. the plain-text mktag format. This does not create an object, just crafts input for "git mktag" to consume.

We are not being paranoid about exhaustive input validation here because we're just about to run git's own "fsck" check on this.

However, if someone injected parameters with extra newlines they could cause subsequent values to be ignored via a crafted message. This someone could also locally craft a tag locally and "git push" it. But allowing e.g. someone to provide their own timestamp here would at best be annoying, and at worst run up against some other assumption (e.g. that some hook check isn't as strict on locally generated data).
