- Split functionality out of WasiEnv so that it can support multi-threading
- Added methods to the VFS File Trait that supporting polling
- Implemented basic time functionality for WASI
- Incorported a yield callback for when WASI processes idle
- Improved the error handling on WASI IO calls
- Reduce the verbose logging on some critical WASI calls (write/read)
- Implemented the missing poll functionality for WASI processes
- Moved the syspoll functionality behind a feature flag to default to WASI method
- Refactored the thread sleeping functionality for WASI processes
- Fixed the files system benchmark which was not compiling
- Modified the file system trait so that it is SYNC and thus can handle multiple threads
- Removed the large mutex around filesystem state and implemented granular locks instead
(this is needed to fix a deadlock scenario on the terminal)
- Split the inodes object apart from the state to fix the deadlock scenario.
- Few minor fixes to some warnings when not using certain features
- Sleeping will now call a callback that can be used by the runtime operator when
a WASI thread goes to sleep (for instance to do other work)
- Fixed a bug where paths that exist on the real file system are leaking into VFS
- Timing functions now properly return a time precision on WASI
- Some improved macros for error handling within syscalls (wasi_try_ok!)
- Refactored the remove_directory WASI function which was not working properly
- Refactored the unlink WASI function which was not working properly
- Refactored the poll WASI function which was not working properly
- Updates some of the tests to make them compile again
- Rewrote the OutputCapturer so that it does leak into the internals
The wasm snippet in the test corresponds to roughly:
```rust
let name = "bananapeach";
banana(a, b, c, name.len() as _, name.as_ptr() as _, f, g, h);
```
however sometime between 2.0 and 2.1 the name pointer is no longer being
passed through as an argument. Instead a 0 gets passed in.
To make things weirder, if `name.as_ptr()` is passed through multiple
times, the second time the pointer will get passed correctly.
2693: Add extra validation to compilers & engines r=ptitSeb a=Amanieu
- Cranelift and singlepass now properly cross-compile with no dependency on the host target.
- Staticlib engine now panics if you try to run a freshly compiled module.
- CPU features used when a module was compiled are now checked against the host CPU features during instantiation.
