2023-04-03Rollup merge of #109722 - hermitcore:read, r=Mark-SimulacrumMatthias Krüger-7/+24
Implement read_buf for RustHermit In principle, this PR extends rust-lang/rust#108326 for RustyHermit.
2023-03-29Rollup merge of #107387 - joboet:hermit_random, r=ChrisDentonMatthias Krüger-2/+11
Use random `HashMap` keys on Hermit Initializing the keys with random data provided by the libOS avoids HashDOS attacks and similar issues. CC `@stlankes`

2023-03-29std: use `cvt` to handle errors from `read_entropy` on Hermitjoboet-9/+3
2023-03-19fix typo in the creation of OpenOptionStefan Lankes-1/+1
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.

2023-02-24move IO traits to std/src/os/hermitStefan Lankes-367/+12
By moving the IO traits, the RustyHermit support is harmonized to of other operating systems.
2023-02-24add support of RustyHermit's BSD socket layerStefan Lankes-455/+795
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.

2022-09-08Rollup merge of #101423 - mkroening:hermit-warnings, r=sanxiynMichael Goulet-4/+0
Fix hermit warnings This fixes two `unused_imprt` and one `dead_code` warning for hermit.
2022-09-08Rollup merge of #101422 - mkroening:hermit-file-time, r=joshtriplettDylan DPC-0/+12
Hermit: Add File::set_time stub This is not supported on hermit yet. This change is required for compiling std.
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.

2022-08-28Support `#[unix_sigpipe = "inherit|sig_dfl|sig_ign"]` on `fn main()`Martin Nordholts-1/+1
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.

2022-02-13make Instant::{duration_since, elapsed, sub} saturating and remove workaroundsThe8472-8/+0
This removes all mutex/atomics based workarounds for non-monotonic clocks and makes the previously panicking methods saturating instead. Effectively this moves the monotonization from `Instant` construction to the comparisons. This has some observable effects, especially on platforms without monotonic clocks: * Incorrectly ordered Instant comparisons no longer panic. This may hide some programming errors until someone actually looks at the resulting `Duration` * `checked_duration_since` will now return `None` in more cases. Previously it only happened when one compared instants obtained in the wrong order or manually created ones. Now it also does on backslides. The upside is reduced complexity and lower overhead of `Instant::now`.

2021-12-09Auto merge of #81156 - DrMeepster:read_buf, r=joshtriplettbors-2/+6
Implement most of RFC 2930, providing the ReadBuf abstraction This replaces the `Initializer` abstraction for permitting reading into uninitialized buffers, closing #42788. This leaves several APIs described in the RFC out of scope for the initial implementation: * read_buf_vectored * `ReadBufs` Closes #42788, by removing the relevant APIs.
