Addison Crump	6b595e7999	Update fuzzers and add building them to CI (#2983 ) * update fuzzers for latest changes * build fuzzers in CI workflow * move fuzz builds before examples, oops * use explicit versioning	2 years ago
Mrmaxmeier	4aebe39e15	fuzzer: bubble up NoInstructionsRemain error instead of trying to handle as exception (#2566 ) Hi, the `vm-implied` fuzzer panics when executing this testcase: ```javascript try { new function() { while (this) {} }(); } catch { } ``` `internal error: entered unreachable code: The NoInstructionsRemain native error cannot be converted to an opaque type` Handling the `NoInstructionsRemain` error upfront instead of going through the VM exception handling logic seems to work.	2 years ago
Addison Crump	c1b5f38d11	VM Fuzzer (#2401 ) This Pull Request offers a basic VM fuzzer which relies on implied oracles (namely, "does it crash or timeout?"). It changes the following: - Adds an insns_remaining field to Context, denoting the number of instructions remaining to execute (only available when fuzzing) - Adds a JsNativeError variant, denoting when the number of instructions has been exceeded (only available when fuzzing) - Adds a VM fuzzer which looks for cases where Boa may crash on an input This offers no guarantees about correctness, only assertion violations. Depends on #2400. Any issues I raise in association with this fuzzer will link back to this fuzzer. You may run the fuzzer using the following commands: ```bash $ cd boa_engine $ cargo +nightly fuzz run -s none vm-implied ``` Co-authored-by: Addison Crump <addison.crump@cispa.de>	2 years ago
Addison Crump	e64a20e2a6	Parser Idempotency Fuzzer (#2400 ) This Pull Request offers a fuzzer which is capable of detecting faults in the parser and interner. It does so by ensuring that the parsed AST remains the same between a parsed source and the result of parsing the `to_interned_string` result of the first parsed source. It changes the following: - Adds a fuzzer for the parser and interner. Any issues I raise in association with this fuzzer will link back to this fuzzer. You may run the fuzzer using the following commands: ```bash $ cd boa_engine $ cargo +nightly fuzz run -s none parser-idempotency ``` Co-authored-by: Addison Crump <addison.crump@cispa.de>	2 years ago
