Expand description
The different executor parameters for changing the execution environment semantics.
Variants§
MaxMemoryPages(u32)
Maximum number of memory pages (64KiB bytes per page) the executor can allocate. A valid value lies within (0, 65536].
StackLogicalMax(u32)
Wasm logical stack size limit (max. number of Wasm values on stack).
A valid value lies within [LOGICAL_MAX_LO
, LOGICAL_MAX_HI
].
For WebAssembly, the stack limit is subject to implementations, meaning that it may vary on different platforms. However, we want execution to be deterministic across machines of different architectures, including failures like stack overflow. For deterministic overflow, we rely on a logical limit, the maximum number of values allowed to be pushed on the stack.
StackNativeMax(u32)
Executor machine stack size limit, in bytes.
If StackLogicalMax
is also present, a valid value should not fall below
128 * StackLogicalMax
.
For deterministic overflow, StackLogicalMax
should be reached before the native stack is
exhausted.
PrecheckingMaxMemory(u64)
Max. amount of memory the preparation worker is allowed to use during
pre-checking, in bytes.
Valid max. memory ranges from PRECHECK_MEM_MAX_LO
to PRECHECK_MEM_MAX_HI
.
PvfPrepTimeout(PvfPrepKind, u64)
PVF preparation timeouts, in millisecond.
Always ensure that precheck_timeout
< lenient_timeout
.
When absent, the default values will be used.
PvfExecTimeout(PvfExecKind, u64)
PVF execution timeouts, in millisecond.
Always ensure that backing_timeout
< approval_timeout
.
When absent, the default values will be used.
WasmExtBulkMemory
Enables WASM bulk memory proposal
