Types

type Format

type Format int
const (
	DefaultMaxObjectsLimit = 1 << 20

	VersionSupported        = 2
	UnknownFormat    Format = 0
	OFSDeltaFormat   Format = 1
	REFDeltaFormat   Format = 2
)

type Reader

type Reader struct {
	// MaxObjectsLimit is the limit of objects to be load in the packfile, if
	// a packfile excess this number an error is throw, the default value
	// is defined by DefaultMaxObjectsLimit, usually the default limit is more
	// than enough to work with any repository, working extremly big repositories
	// where the number of object is bigger the memory can be exhausted.
	MaxObjectsLimit uint32

	// Format specifies if we are using ref-delta's or ofs-delta's, choosing the
	// correct format the memory usage is optimized
	// https://github.com/git/git/blob/8d530c4d64ffcc853889f7b385f554d53db375ed/Documentation/technical/protocol-capabilities.txt#L154
