Functions

func NewPackfileIter 

func NewPackfileIter(
	fs billy.Filesystem,
	f billy.File,
	idxFile billy.File,
	t plumbing.ObjectType,
	keepPack bool,
	largeObjectThreshold int64,
) (storer.EncodedObjectIter, error)

NewPackfileIter returns a new EncodedObjectIter for the provided packfile and object type. Packfile and index file will be closed after they're used. If keepPack is true the packfile won't be closed after the iteration finished.

EncodedObject returns the object with the given hash, by searching for it in the packfile and the git object directories.

func (*ObjectStorage) EncodedObjectSize 

func (s *ObjectStorage) EncodedObjectSize(h plumbing.Hash) (
	size int64, err error)

SetEncodedObject adds a new object to the storage.

type Options 

type Options struct {
	// ExclusiveAccess means that the filesystem is not modified externally
	// while the repo is open.
	ExclusiveAccess bool
	// KeepDescriptors makes the file descriptors to be reused but they will
	// need to be manually closed calling Close().
	KeepDescriptors bool
	// MaxOpenDescriptors is the max number of file descriptors to keep
	// open. If KeepDescriptors is true, all file descriptors will remain open.
	MaxOpenDescriptors int
	// LargeObjectThreshold maximum object size (in bytes) that will be read in to memory.
	// If left unset or set to 0 there is no limit
	LargeObjectThreshold int64
}

Options holds configuration for the storage.
