2024-10-14Rollup merge of #131616 - RalfJung:const_ip, r=tgross35Matthias Krüger-3/+0
merge const_ipv4 / const_ipv6 feature gate into 'ip' feature gate https://github.com/rust-lang/rust/issues/76205 has been closed a while ago, but there are still some functions that reference it. Those functions are all unstable *and* const-unstable. There's no good reason to use a separate feature gate for their const-stability, so this PR moves their const-stability under the same gate as their regular stability, and therefore removes the remaining references to https://github.com/rust-lang/rust/issues/76205.

sys/unix: add comments for some Miri fallbacks
2024-10-13library: xous: mark alloc as `FIXME(static_mut_refs)`Sean Cross-0/+3
The allocator on Xous is now throwing warnings because the allocator needs to be mutable, and allocators hand out mutable pointers, which the `static_mut_refs` lint now catches. Give the same treatment to Xous as wasm, at least until a solution is devised for fixing the warning on wasm. Signed-off-by: Sean Cross <sean@xobs.io>

Process arguments and environment variables are both passed by way of Application Parameters. These are a TLV format that gets passed in as the second process argument. This patch combines both as they are very similar in their decode. Signed-off-by: Sean Cross <sean@osdyne.com>

2024-10-12Rollup merge of #131233 - joboet:stdout-before-main, r=tgross35Trevor Gross-23/+42
std: fix stdout-before-main Fixes #130210. Since #124881, `ReentrantLock` uses `ThreadId` to identify threads. This has the unfortunate consequence of breaking uses of `Stdout` before main: Locking the `ReentrantLock` that synchronizes the output will initialize the thread ID before the handle for the main thread is set in `rt::init`. But since that would overwrite the current thread ID, `thread::set_current` triggers an abort. This PR fixes the problem by using the already initialized thread ID for constructing the main thread handle and allowing `set_current` calls that do not change the thread's ID.

2024-10-11Rollup merge of #130962 - nyurik:opts-libs, r=cuviperTrevor Gross-11/+11
Migrate lib's `&Option<T>` into `Option<&T>` Trying out my new lint https://github.com/rust-lang/rust-clippy/pull/13336 - according to the [video](https://www.youtube.com/watch?v=6c7pZYP_iIE), this could lead to some performance and memory optimizations. Basic thoughts expressed in the video that seem to make sense: * `&Option<T>` in an API breaks encapsulation: * caller must own T and move it into an Option to call with it * if returned, the owner must store it as Option<T> internally in order to return it * Performance is subject to compiler optimization, but at the basics, `&Option<T>` points to memory that has `presence` flag + value, whereas `Option<&T>` by specification is always optimized to a single pointer.

2024-10-09Rollup merge of #131449 - nickrum:wasip2-net-decouple-fd, r=alexcrichtonMatthias Krüger-18/+58
Decouple WASIp2 sockets from WasiFd This is a follow up to #129638, decoupling WASIp2's socket implementation from WASIp1's `WasiFd` as discussed with `@alexcrichton.` Quite a few trait implementations in `std::os::fd` rely on the fact that there is an additional layer of abstraction between `Socket` and `OwnedFd`. I thus had to add a thin `WasiSocket` wrapper struct that just "forwards" to `OwnedFd`. Alternatively, I could have added a lot of conditional compilation to `std::os::fd`, which feels even worse. Since `WasiFd::sock_accept` is no longer accessible from `TcpListener` and since WASIp2 has proper support for accepting sockets through `Socket::accept`, the `std::os::wasi::net` module has been removed from WASIp2, which only contains a single `TcpListenerExt` trait with a `sock_accept` method as well as an implementation for `TcpListener`. Let me know if this is an acceptable solution.

2024-10-05Rollup merge of #131094 - joboet:lazy_once_box, r=ibraheemdevMatthias Krüger-284/+185
std: replace `LazyBox` with `OnceBox` This PR replaces the `LazyBox` wrapper used to allocate the pthread primitives with `OnceBox`, which has a more familiar API mirroring that of `OnceLock`. This cleans up the code in preparation for larger changes like #128184 (from which this PR was split) and allows some neat optimizations, like avoid an acquire-load of the allocation pointer in `Mutex::unlock`, where the initialization of the allocation must have already been observed. Additionally, I've gotten rid of the TEEOS `Condvar` code, it's just a duplicate of the pthread one anyway and I didn't want to repeat myself.

impl `Default` for `HashMap`/`HashSet` iterators that don't already have it This is a follow-up to #128261 that isn't included in that PR because it depends on: * [x] rust-lang/hashbrown#542 (`Default`) * [x] `hashbrown` release containing above It also wasn't included in #128261 initially and should have its own FCP, since these are also insta-stable. Changes added: * `Default for hash_map::{Iter, IterMut, IntoIter, IntoKeys, IntoValues, Keys, Values, ValuesMut}` * `Default for hash_set::{Iter, IntoIter}` Changes that were added before FCP, but are being deferred to later: * `Clone for hash_map::{IntoIter, IntoKeys, IntoValues} where K: Clone, V: Clone` * `Clone for hash_set::IntoIter where K: Clone`
