https://github.com/bytecodealliance/wit-bindgen/pull/228 added support for parsing the `stream` type. As noted in https://github.com/bytecodealliance/wit-bindgen/pull/228#pullrequestreview-995028227, there are many `todo!`s left for the implementation in the canonical ABI and bindings implementations.

rust-wasm export cannot find imported handle types

This repository: https://github.com/sunfishcode/import-export-demo contains a wit-bindgen project which imports provider.wit: ```wit resource thing { frob: function() } ``` and exports runner.wit: ```wit use { thing } from provider doit: function(it:...

#119 requires identifiers to be lower-case [stream-safe] [NFC] [kebab-case] where each part delimited by '-'s starts with a `XID_Start` scalar value with a zero canonical combining class. Concerns which are...

Use `dlsym` to resolve `__vdso_clock_gettime` etc.?

2

In dynamically linked executables, we should be able to `dlopen` the "linux-vdso.so" library and use `dlsym` to obtain symbols like "__vdso_clock_gettime" instead of parsing the vDSO ELF image manually. An...

Reading into uninitialized buffers

2

Currently, [`read`](https://docs.rs/rsix/latest/rsix/io/fn.read.html) takes a `&mut [u8]`. That's fine for many use cases, but it does require the buffer to be initialized before calling `read`, so it's currently not possible to...

std::process::Command and I/O safety

10

Following up on a discussion in #97: [`std::process::Command`](https://doc.rust-lang.org/stable/std/process/struct.Command.html) has a safe API for spawning child processes. Its documentation doesn't mention non-`O_CLOEXEC` file descriptors, but from some experimenting, child processes do...

Rustix's [futex function](https://docs.rs/rustix/latest/rustix/thread/fn.futex.html) can perform several different operations, as determined by a `FutexOperation` argument. However, as documented in the Arguments section of [Linux's man page](https://man7.org/linux/man-pages/man2/futex.2.html), in some operations, some of...

`pid_t` is universally signed, however rustix's linux_raw backend makes `RawPid` be `u32`. This complicates porting code from libc to rustix.

As discussed in https://github.com/bytecodealliance/rustix/pull/165, `wait` is a tricky function to test from within the test harness because it depends on knowing that nothing else in the process is creating child...
