- 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
This patch takes the entire `wasmer-js` crate and merges it into the
`wasmer` crate.
Inside the `lib/api/src/` directory, there are 2 new directories:
1. a new `sys` directory, which contains the usual `wasmer` crate
implementation,
2. a new directory `js`, which contains the implementation of
`wasmer-js`.
The `Cargo.toml` file is still compatible. The `default` feature
fallbacks to `sys-default`, which enables the `sys` feature. All
features related to compilers or engines or anything else prior this
patch, activates the `sys` feature.
Parallel to that, there is a `js-default` and `js` features.
The `Cargo.toml` file is extensively documented to explain what are
dependencies, dev-dependencies, features and other sections related to
`sys` or to `js`.
There is a bug with `wasm_bindgen_test` where it doesn't compile or
look for tests in `tests/*/<test>.rs`. The hack is to name files
`tests/js_<test>.rs`. Ugly, but it works.
