When using the pooling instance allocator for running spec tests we have to make sure that the configured limits of the allocator aren't so low as to cause the spec tests to fail due to resource exhaustion issues or similar. This commit adds in minimum thresholds for instance size as well as instance count. While here this goes ahead and refactors everything here to look similar.
Fuzzing Infrastructure for Wasmtime
This crate provides test case generators and oracles for use with fuzzing.
These generators and oracles are generally independent of the fuzzing engine
that might be using them and driving the whole fuzzing process (e.g. libFuzzer
or AFL). As such, this crate does not contain any actual fuzz targets
itself. Those are generally just a couple lines of glue code that plug raw input
from (for example) libFuzzer into a generator, and then run one or more
oracles on the generated test case.
If you're looking for the actual fuzz target definitions we currently have, they
live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and
libFuzzer.
