Function CompatibilizeSampleTypes

profile/merge.go:586–597

CompatibilizeSampleTypes makes profiles compatible to be compared/merged. It keeps sample types that appear in all profiles only and drops/reorders the sample types as necessary. In the case of sample types order is not the same for given profiles the order is derived from the first profile. Profi

(ps []*Profile)

//
// It returns an error if the sample type's intersection is empty.
func CompatibilizeSampleTypes(ps []*Profile) error {
	sTypes := commonSampleTypes(ps)
	if len(sTypes) == 0 {
		return fmt.Errorf("profiles have empty common sample type list")
	}
	for _, p := range ps {
		if err := compatibilizeSampleTypes(p, sTypes); err != nil {
			return err
		}
	}
	return nil
}

// commonSampleTypes returns sample types that appear in all profiles in the
// order how they ordered in the first profile.
