Functions

func FirstParent

func FirstParent(r *gogit.Repository, c *object.Commit) (*object.Commit, error)

FirstParent returns the first parent of a commit. For a merge commit this is the parent which is usually depicted on the left.

func FirstParentList

func FirstParentList(r *gogit.Repository, c *object.Commit) ([]*object.Commit, error)

FirstParentList visits the ancestors of c using the FirstParent func. It returns the list of visited commits.

func MergePoints

func MergePoints(r *gogit.Repository, mainLine []*object.Commit) (map[plumbing.Hash]*object.Commit, error)

MergePoints creates a look-up table from feature branch commit hashes to their merge commits onto the given mainline.

func SourceCommitToDstCommits

func SourceCommitToDstCommits(r *gogit.Repository, commitMsgTag string, dstFirstParents, srcFirstParents []*object.Commit) (map[plumbing.Hash]plumbing.Hash, error)

SourceCommitToDstCommits returns a mapping from all kube mainline commits to the corresponding dst commits after collapsing using "git filter-branch --sub-directory-filter":

func SourceHash

func SourceHash(c *object.Commit, tag string) plumbing.Hash

SourceHash extracts kube commit from commit message The baseRepoName default to "kubernetes". TODO: Refactor so we take the commitMsgTag as argument and don't need to construct the ancientSyncCommitSubjectPrefix or sourceCommitPrefix.
