Tracking Issue for restructuring `std::sys` #117276

joboet · 2023-10-27T11:09:17Z

On Wednesday, the libs-team discussed reorganizing the platform-specific modules inside std, namely sys and sys_common into a new structure. These modules will be merged into one sys module with a feature-first organization:

the submodules of sys, named after the feature they implement, contain all the implementations of the different platforms and provide a uniform interface that the rest of std may depend on. E.g. sys::thread_local, sys::fs or sys::thread_parking.
sys::pal contains platform-specific generic API wrappers like ~~FileDesc~~ cvt (UNIX) used to implement these features. E.g. sys::pal::unix, sys::pal::windows or (perhaps) sys::pal::apple.

The rest of std, modulo std::os, should now only depend on sys::feature_name and not sys::pal. The implementations themselves may however depend on other parts of std as necessary.

…sDenton Move platform modules into `sys::pal` This is the initial step of rust-lang#117276. `sys` just re-exports everything from the current `sys` for now, I'll move the implementations for the individual features one-by-one after this PR merges.

Move OS String implementation into `sys` Part of rust-lang#117276. The new structure is really useful here, since we can easily eliminate a number of ugly `#[path]`-based imports. In the future, it might be good to move the WTF-8 implementation directly to the OS string implementation, I cannot see it being used anywhere else. That is a story for another PR, however.

Something that just occurred to me is that we might want to add commits to https://github.com/rust-lang/rust/blob/master/.git-blame-ignore-revs if they're purely moving files. This allows GitHub's blame interface to ignore them.

std: move network code into `sys` As per rust-lang#117276, this PR moves `sys_common::net` and the `sys::pal::net` into the newly created `sys::net` module. In order to support rust-lang#135141, I've moved all the current network code into a separate `connection` module, future functions like `hostname` can live in separate modules. I'll probably do a follow-up PR and clean up some of the actual code, this is mostly just a reorganization.

std: move `io` module out of `pal`, get rid of `sys_common::io` Part of rust-lang#117276. This does two related things: 1. It moves the platform-specific definitions for `IoSlice`, `IoSliceMut` and `is_terminal` out of `pal` and into `sys` and unifies some of them. 2. It gets rid of `sys_common::io`, moving the non-platform-specific test helpers into `std::test_helpers` and the buffer size definition to the new `sys::io` module.

As per rust-lang#117276, this moves the platform definitions of `Stdout` and friends into `sys`. This PR also unifies the UNIX and Hermit implementations and moves the `__rust_print_err` function needed by libunwind on SGX into the dedicated module for such helper functions.

As per rust-lang#117276, this moves the implementations of `Process` and friends out of the `pal` module and into the `sys` module, removing quite a lot of error-prone `#[path]` imports in the process (hah, get it ;-)). I've also made the `zircon` module a dedicated submodule of `pal::unix`, hopefully we can move some other definitions there as well (they are currently quite a lot of duplications in `sys`). Also, the `ensure_no_nuls` function on Windows now lives in `sys::pal::windows` – it's not specific to processes and shared by the argument implementation.

How should file descriptors / handles be organized, since they are platform-dependent features?
