func AggregateStacks ¶

func AggregateStacks(profile *pprofprofile.Profile) ([][]string, error)

AggregateStacks aggregates the stacks of the given samples into a single slice.

func AnyStackContains ¶

func AnyStackContains(foundStacks [][]string, stack []string) bool

AnyStackContains returns whether the passed string slice is contained in any of the slice of string slices. This is used to ensure that a stacktrace is contained in a given profile.

func ChooseArch ¶

func ChooseArch() (string, error)

Choose host architecture.

func IsRunningOnCI ¶

func IsRunningOnCI() bool

IsRunningOnCI returns whether we might be running in a continuous integration environment. GitHub Actions and most other CI platforms set the CI environment variable.

func NewTestProfiler ¶

func NewTestProfiler(
	logger log.Logger,
	reg *prometheus.Registry,
	ofp *objectfile.Pool,
	profileStore profiler.ProfileStore,
	tempDir string,
	config *cpu.Config,
	relabelConfig ...*relabel.Config,
) (*cpu.CPU, error)

func ParsePrometheusMetricsEndpoint ¶

func ParsePrometheusMetricsEndpoint(content string) map[string]string

ParsePrometheusMetricsEndpoint does some very light parsing of the metrics published in Prometheus.

func ProfileDuration ¶

func ProfileDuration() time.Duration

ProfileDuration sets the profile runtime to a shorter time period when running outside of CI. The logic for this is that very loaded systems, such as GH actions might take a long time to spawn processes. By increasing the runtime we reduce the chance of flaky test executions, but we shouldn't have to pay this price during local dev.

func RequireAnyStackContains ¶

func RequireAnyStackContains(t *testing.T, foundStacks [][]string, stack []string)

RequireAnyStackContains asserts that the given stack is contained in any of the given stacks.

func WaitForServer ¶

func WaitForServer(url string) error

WaitForServer waits up to 100ms * 5. Returns an error if the HTTP server is not reachable and a nil error if it is.
