Function Documentation

NormalizeScenarioForExecution()

void proto_fuzzer::NormalizeScenarioForExecution

(

curl::fuzzer::proto::Scenario *

scenario

)

Apply execution-only allocation-failure safety rules.

Fixed target postprocessors call this while serializing mutations; the shared runtime repeats it so the compatibility target keeps its persistent wire format while executing the same bounded, safe plan.

Parameters

scenario

Parsed scenario to canonicalize in place.

NormalizeScenarioForTarget()

void proto_fuzzer::NormalizeScenarioForTarget	(	curl::fuzzer::proto::Scenario *	scenario,
		TargetProfile	profile,
		ConditionalEligibilityPruner	prune_conditional_eligibility )

Complete normalization for a loaded or mutated fixed-target Scenario.

Besides dispatch and timing controls, fixed lanes trim repeated-field and metadata suffixes that the runtime cannot consume. WebSocket lanes also remove follow-on sockets and MIME bodies their single-upgrade driver cannot use; all remaining observable bytes, options, frames, and probes stay fuzz-controlled. Option oneofs are canonicalized before final string bounds, so repeated normalization preserves the same serialized message. The compatibility profile leaves the entire input unchanged.

Parameters

scenario	Scenario to canonicalize in place.
profile	Target lane whose invariants must be restored.
prune_conditional_eligibility	Generated profile callback, or nullptr when the caller has no conditional eligibility to apply.
