bxq2011hust labeled issue #3571:

Thanks for filing a bug report! Please fill out the TODOs below.

Note: if you want to report a security issue, please read our security policy!

Test Case

upload Wasm file here

Steps to Reproduce

first, call a wasm function
second, in the called wasm function, call host function, host function call a function in another wasm instance, then calll a host function which return a trap to interrupt the execution and return result to first wasm call.
third, the second wasm call maybe in the same thread as the first wasm call, because we use boost coroutine

Expected Results

What do you expect to happen?

just return the trap with user defined message

Actual Results

thread '<unnamed>' panicked at 'called Option::unwrap() on a None value', crates/runtime/src/traphandlers.rs:84:27

and wasmtime return a trap with called Option::unwrap() on a None value

Versions and Environment

Wasmtime version or commit: v0.31.0

Operating system: Ubuntu 20.04

Architecture: x86_64

Extra Info

thread '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value', crates/runtime/src/traphandlers.rs:84:27

Maybe call two wasm instance use one thread is not permitted? or there is a problem use trap to interrupt execution?

bjorn3 commented on issue #3571:

Boost coroutines don't save and restore the required TLS variables. If you want to interleave multiple wasm module executions on the same thread you will have to use rust async and the dedicated api for wasmtime's async support. This saves and restores all TLS variables as necessafy and switches the wasm stack for you. See https://github.com/bytecodealliance/wasmtime/blob/06a93d33462f5460a1c5289f4001ccde49bf562d/crates/wasmtime/src/store.rs#L1259 and the https://github.com/bytecodealliance/wasmtime/blob/main/examples/tokio/main.rs example.

Maybe call two wasm instance use one thread is not permitted? or there is a problem use trap to interrupt execution?

hello, I use the rust wrapper wasmtime's async interface instantiate_async and call_async, also called by boost coroutines, but still got the same error when host function returns a Trap. Any suggestions?

bxq2011hust reopened issue #3571:

Thanks for filing a bug report! Please fill out the TODOs below.

Note: if you want to report a security issue, please read our security policy!

Test Case

upload Wasm file here

Steps to Reproduce

first, call a wasm function
second, in the called wasm function, call host function, host function call a function in another wasm instance, then calll a host function which return a trap to interrupt the execution and return result to first wasm call.
third, the second wasm call maybe in the same thread as the first wasm call, because we use boost coroutine

Expected Results

What do you expect to happen?

just return the trap with user defined message

Actual Results

thread '<unnamed>' panicked at 'called Option::unwrap() on a None value', crates/runtime/src/traphandlers.rs:84:27

and wasmtime return a trap with called Option::unwrap() on a None value

Versions and Environment

Wasmtime version or commit: v0.31.0

Operating system: Ubuntu 20.04

Architecture: x86_64

Extra Info

thread '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value', crates/runtime/src/traphandlers.rs:84:27

hello, I use rust wrap the wasmtime's async interface instantiate_async and call_async, also called by boost coroutines, but still got the same error when host function returns a Trap. Any suggestions? @alexcrichton @bjorn3

alexcrichton commented on issue #3571:

@bxq2011hust if you're using boost coroutines then this is the same issue as before I believe. Wasmtime has a TLS variable which must be saved/restored across coroutine switches which I suspect that boost does not have support for. Wasmtime, at this time, does not support being called from an external coroutine library.

bxq2011hust commented on issue #3571:

@bxq2011hust if you're using boost coroutines then this is the same issue as before I believe. Wasmtime has a TLS variable which must be saved/restored across coroutine switches which I suspect that boost does not have support for. Wasmtime, at this time, does not support being called from an external coroutine library.

ok, got it, thanks

Thanks for filing a bug report! Please fill out the TODOs below.

Note: if you want to report a security issue, please read our security policy!

Test Case

upload Wasm file here

Steps to Reproduce

first, call a wasm function
second, in the called wasm function, call host function, host function call a function in another wasm instance, then calll a host function which return a trap to interrupt the execution and return result to first wasm call.
third, the second wasm call maybe in the same thread as the first wasm call, because we use boost coroutine

Expected Results

What do you expect to happen?

just return the trap with user defined message

Actual Results

thread '<unnamed>' panicked at 'called Option::unwrap() on a None value', crates/runtime/src/traphandlers.rs:84:27

and wasmtime return a trap with called Option::unwrap() on a None value

Versions and Environment

Wasmtime version or commit: v0.31.0

Operating system: Ubuntu 20.04

Architecture: x86_64

Extra Info

thread '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value', crates/runtime/src/traphandlers.rs:84:27

Maybe call two wasm instance use one thread is not permitted? or there is a problem use trap to interrupt execution?
