func (h *BasicHandler) GetChange(ref string) (*remotetypes.ItemChange, error)

GetChange computes and returns the change made to the given reference

func (*BasicHandler) HandleAnnouncement 

func (h *BasicHandler) HandleAnnouncement(cb func(errCount int))

HandleAnnouncement announces the repository name, pushed commit and tag objects. cb is called with the number of failed announcements.

func (*BasicHandler) HandleAuthorization 

func (h *BasicHandler) HandleAuthorization(ur *packp.ReferenceUpdateRequest) error

func (*BasicHandler) HandlePushNote 

func (h *BasicHandler) HandlePushNote(note types.PushNote) (err error)

HandlePushNote implements Handler by handing incoming push note

func (*BasicHandler) HandleRefMismatch 

func (h *BasicHandler) HandleRefMismatch(note types.PushNote, ref string, netMismatch bool) (err error)

HandleRefMismatch handles cases where a reference in the push note differs from the hash of its corresponding local or network reference hash. We react by attempting resyncing the reference.

func (*BasicHandler) HandleReference 

func (h *BasicHandler) HandleReference(ref string) (errs []error)

HandleReference implements Handler

func (*BasicHandler) HandleReferences 

func (h *BasicHandler) HandleReferences() error

HandleReferences implements Handler. It processes pushed references.

func (*BasicHandler) HandleReversion 

func (h *BasicHandler) HandleReversion() []error

HandleReversion reverts the pushed references back to their pre-push state. It will do nothing and return nil if already called successfully.

func (*BasicHandler) HandleStream 

func (h *BasicHandler) HandleStream(
	packfile io.Reader,
	gitReceive io.WriteCloser,
	gitRcvCmd util.Cmd,
	pktEnc *pktline.Encoder,
) error

HandleStream implements Handler. It reads the packfile and pipes it to git.

func (*BasicHandler) HandleUpdate 

func (h *BasicHandler) HandleUpdate(targetNote types.PushNote) (err error)

HandleUpdate implements Handler

func (*BasicHandler) WaitForPushTx added in v0.0.29 

func (h *BasicHandler) WaitForPushTx() chan interface{}

WaitForPushTx waits for the final push transaction to be created and added to the mempool. It will return error if the tx was rejected. An error is returned if the tx was not successfully added to the pool after 15 minutes. On success, it returns the tx hash

type HandleAuthorizationFunc 

type HandleAuthorizationFunc func(ur *packp.ReferenceUpdateRequest) error

HandleAuthorizationFunc describes a function for checking authorization to access a reference

type HandleReferenceFunc 

type HandleReferenceFunc func(ref string) []error

HandleReferenceFunc describes a function for processing a reference

type MakeReferenceUpdateRequestPackFunc 

type MakeReferenceUpdateRequestPackFunc func(tx pushtypes.PushNote) (io.ReadSeeker, error)

type Reader 

type Reader struct {
	References PackedReferences
	Objects    PushedObjects
	// contains filtered or unexported fields
}

PushReader inspects push data from git client, extracting data such as the pushed references, objects and object to reference mapping. It also pipes the pushed stream to a destination (git-receive-pack) when finished.

func NewPushReader 

func NewPushReader(dst io.WriteCloser, repo types.LocalRepo) (*Reader, error)
