Package-Level Functions (total 3)

func HardCodedPkgID(pkgpath string) int HardCodedPkgID returns the hard-coded ID for the specified package path, or -1 if we don't use a hard-coded ID. Hard-coded IDs start at -2 and decrease as we go down the list.

func ParseCounterMode(mode string) CounterMode

func Round4(x int) int

Package-Level Variables (total 2)

var CovCounterMagic [4]byte CovCounterMagic holds the magic string for a coverage counter-data file.

var CovMetaMagic [4]byte CovMetaMagic holds the magic string for a meta-data file.

Package-Level Constants (total 24)

const CounterFilePref = "covcounters" CounterFilePref is the file prefix used when emitting coverage data output files. CounterFileTemplate describes the format of the file name: prefix followed by meta-file hash followed by process ID followed by emit UnixNanoTime.

const CounterFileRegexp = "^%s\\.(\\S+)\\.(\\d+)\\.(\\d+)+$"

const CounterFileTempl = "%s.%x.%d.%d"

const CounterFileVersion = 1 CounterFileVersion stores the most recent counter data file version.

const CovMetaHeaderSize = 44 // keep in sync with above

const CtrGranularityInvalid CounterGranularity = 0

const CtrGranularityPerBlock CounterGranularity = 1

const CtrGranularityPerFunc CounterGranularity = 2

const CtrModeAtomic CounterMode = 3 // "atomic" mode

const CtrModeCount CounterMode = 2 // "count" mode

const CtrModeInvalid CounterMode = 0

const CtrModeRegOnly CounterMode = 4 // registration-only pseudo-mode

const CtrModeSet CounterMode = 1 // "set" mode

const CtrModeTestMain CounterMode = 5 // testmain pseudo-mode

const CtrRaw CounterFlavor = 1 "Raw" representation: all values (pkg ID, func ID, num counters, and counters themselves) are stored as uint32's.

const CtrULeb128 CounterFlavor = 2 "ULeb" representation: all values (pkg ID, func ID, num counters, and counters themselves) are stored with ULEB128 encoding.

const FirstCtrOffset = 3

const FuncIdOffset = 2

const MetaFilePref = "covmeta" MetaFilePref is a prefix used when emitting meta-data files; these files are of the form "covmeta.<hash>", where hash is a hash computed from the hashes of all the package meta-data symbols in the program.

const MetaFilesFileName = "metafiles.txt" Name of file within the "go test -cover" temp coverdir directory containing a list of meta-data files for packages being tested in a "go test -coverpkg=... ..." run. This constant is shared by the Go command and by the coverage runtime.

const MetaFileVersion = 1 MetaFileVersion contains the current (most recent) meta-data file version.

const NotHardCoded = -1 NotHardCoded is a package pseudo-ID indicating that a given package is not part of the runtime and doesn't require a hard-coded ID.

const NumCtrsOffset = 0

const PkgIdOffset = 1
