Module: Perfgate::Fingerprints::WorkloadDefinition

Defined in:
lib/perfgate/fingerprints/workload_definition.rb

Overview

Computes a per-workload definition hash from the properties that, if changed, would make a historical run incomparable to a new one (spec section 15.4): the workload's id, its sample/warmup counts, and the set of metrics it records. Hashing the workload's source code (to detect behavioral changes even when these properties are unchanged) is explicitly deferred -- the spec notes this requires normalizing formatting/whitespace-only diffs, which is a larger follow-up.
