The Universal type was essentially a builder of engines that's given a
compiler backend and creates an Engine with .engine() method. The name
was not clear.
Since there's one engine now, it doesn't make sense to initialize a
`Store` with the engine specifically. It's an extra redundant step for
the API user.
- Introduced the virtual BUS interface used for RPC between web assembly apps
- Introduced the virtual networking interface used to implement networking
for web assembly apps
- Implemented a local implementation of the virtual networking
(available behind the feature toggle 'host-net' on the 'wasi' package)
- Fixed up some of the examples from the wasmer3 branch
- Refactored the WASI implementations so they support wasm64-wasi
- WASIX is behind its own namespaces for both 32bit and 64bit implementations
- Fixed the wasi_pipes unit test which was using internals that are no longer exposed - instead made the pipes clonable
- 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
