2024-01-11std: begin moving platform support modules into `pal`joboet-1981/+0
2023-10-19Auto merge of #116132 - darthunix:connect_poll, r=cuviperbors-0/+6
Make TCP connect handle EINTR correctly According to the [POSIX](https://pubs.opengroup.org/onlinepubs/009695399/functions/connect.html) standard, if connect() is interrupted by a signal that is caught while blocked waiting to establish a connection, connect() shall fail and set errno to EINTR, but the connection request shall not be aborted, and the connection shall be established asynchronously. When the connection has been established asynchronously, select() and poll() shall indicate that the file descriptor for the socket is ready for writing. The previous implementation differs from the recomendation: in a case of the EINTR we tried to reconnect in a loop and sometimes get EISCONN error (this problem was originally detected on MacOS). 1. More details about the problem in an [article](http://www.madore.org/~david/computers/connect-intr.html). 2. The original [issue](https://git.picodata.io/picodata/picodata/tarantool-module/-/issues/157).
2023-10-13Make TCP connect() handle EINTR correctlyDenis Smirnov-0/+6
According to the POSIX standard, if connect() is interrupted by a signal that is caught while blocked waiting to establish a connection, connect() shall fail and set errno to EINTR, but the connection request shall not be aborted, and the connection shall be established asynchronously. If asynchronous connection was successfully established after EINTR and before the next connection attempt, OS returns EISCONN that was handled as an error before. This behavior is fixed now and we handle it as success. The problem affects MacOS users: Linux doesn't return EISCONN in this case, Windows connect() can not be interrupted without an old-fashoin WSACancelBlockingCall function that is not used in the library. So current solution gives connect() as OS specific implementation.

2023-09-03Rollup merge of #115489 - saethlin:is-interrupted, r=thomccMatthias Krüger-2/+2
Use std::io::Error::is_interrupted everywhere In https://github.com/rust-lang/rust/pull/115228 I introduced this helper and started using it, this PR uses it to replace all applicable uses of `std::io::Error::kind`. The justification is the same; for whatever reason LLVM totally flops optimizing `Error::kind` so it's nice to use it less. FYI ``@mkroening`` I swear the hermit changes look good, but I was so sure about the previous PR.

fix(sys/hermit): add is_interrupted https://github.com/rust-lang/rust/pull/115228 broke compilation for Hermit by not adding a Hermit implementation of is_interrupted.

This function does not exist as of hermit-sys 0.4.1 [1]. Once std does not call this function, we can remove it entirely.

Fix `checked_{add,sub}_duration` incorrectly returning `None` when `other` has more than `i64::MAX` seconds Use `checked_{add,sub}_unsigned` in `checked_{add,sub}_duration` so that the correct result is returned when adding/subtracting durations with more than `i64::MAX` seconds.

Due to this typo we have to build a workaround for issue hermitcore/libhermit-rs#191. RustyHermit is a tier 3 platform and backward compatibility does not have to be guaranteed.

RustHermit publishs a new kernel interface and supports a common BSD socket layer. By supporting this interface, the implementation can be harmonized to other operating systems. To realize this socket layer, the handling of file descriptors is also harmonized to other operating systems.

2022-09-04Auto merge of #100576 - joboet:movable_const_remutex, r=Mark-Simulacrumbors-3/+0
Make `ReentrantMutex` movable and `const` As `MovableMutex` is now `const`, it can be used to simplify the implementation and interface of the internal reentrant mutex type. Consequently, the standard error stream does not need to be wrapped in `OnceLock` and `OnceLock::get_or_init_pin()` can be removed.

This makes it possible to instruct libstd to never touch the signal handler for `SIGPIPE`, which makes programs pipeable by default (e.g. with `./your-program | head -n 1`) without `ErrorKind::BrokenPipe` errors.
