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 = 16 + 4 + 4 + 4 + 4 + 4 + 4 + 4 // keep in sync with above

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 MetaFileVersion = 1

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

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 NotHardCoded = -1
