2023-09-22Rollup merge of #116038 - the8472:panic-on-sched_getaffinity-bug, r=cuviperMatthias Krüger-6/+19
Fall back to _SC_NPROCESSORS_ONLN if sched_getaffinity returns an empty mask Followup to #115946 A gentler fix for #115868, one that doesn't panic, [suggested on zulip](https://rust-lang.zulipchat.com/#narrow/stream/259402-t-libs.2Fmeetings/topic/Meeting.202023-09-19/near/391942927) In that situation - on the buggy kernel versions - a zero-mask means no affinities have been set so `_SC_NPROCESSORS_ONLN` provides the right value.
2023-09-22Rollup merge of #114379 - RalfJung:command-removed-env-vars, r=m-ou-seMatthias Krüger-2/+68
Command: also print removed env vars There is no real shell syntax for unsetting an env var so easily, so we have to make one up. But we already do that for showing the 'program' name so I hope that's okay here, too. No strong opinion on what that should look like, I went with `unset(VAR_NAME)` for now.

Rename BoxMeUp to PanicPayload. "BoxMeUp" is not very clear. Let's rename that to a description of what it actually represents: a panic payload. This PR also renames the structs that implement this trait to have more descriptive names. Part of https://github.com/rust-lang/rust/issues/116005 r? `@oli-obk`
2023-09-20Auto merge of #115542 - saethlin:fileencoder-is-bufwriter, r=WaffleLapkinbors-0/+1
Simplify/Optimize FileEncoder FileEncoder is basically a BufWriter except that it exposes access to the not-written-to-yet region of the buffer so that some users can write directly to the buffer. This strategy is awesome because it lets us avoid calling memcpy for small copies, but the previous strategy was based on the writer accessing a `&mut [MaybeUninit<u8>; N]` and returning a `&[u8]` which is an API which currently mandates the use of unsafe code, making that interface in general not that appealing. So this PR cleans up the FileEncoder implementation and builds on that general idea of direct buffer access in order to prevent `memcpy` calls in a few key places when encoding the dep graph and rmeta tables. The interface used here is now 100% safe, but with the caveat that internally we need to avoid trusting the number of bytes that the provided function claims to have written. The original primary objective of this PR was to clean up the FileEncoder implementation so that the fix for the following issues would be easy to implement. The fix for these issues is to correctly update self.buffered even when writes fail, which I think it's easy to verify manually is now done, because all the FileEncoder methods are small.

2023-09-20Auto merge of #115753 - tgross35:threadinfo-refactor, r=thomccbors-16/+21
Refactor `thread_info` to remove the `RefCell` `thread_info` currently uses `RefCell`-based initialization. Refactor this to use `OnceCell` instead which is more performant and better suits the needs of one-time initialization. This is nobody's bottleneck but OnceCell checks are a single `cmp` vs. `RefCell<Option>` needing runtime logic

2023-09-19Auto merge of #104101 - betrusted-io:xous-libstd-initial, r=bjorn3bors-4/+2473
Add initial libstd support for Xous This patchset adds some minimal support to the tier-3 target `riscv32imac-unknown-xous-elf`. The following features are supported: * alloc * thread creation and joining * thread sleeping * thread_local * panic_abort * mutex * condvar * stdout Additionally, internal support for the various Xous primitives surrounding IPC have been added as part of the Xous FFI. These may be exposed as part of `std::os::xous::ffi` in the future, however for now they are not public. This represents the minimum viable product. A future patchset will add support for networking and filesystem support.

2023-09-17Rollup merge of #114965 - benschulz:mpsc-drop, r=dtolnayDylan DPC-15/+0
Remove Drop impl of mpsc Receiver and (Sync)Sender This change removes the empty `Drop` implementations for `mpsc::Receiver`, `mpsc::Sender` and `mpsc::SyncSender`. These implementations do not specify `#[may_dangle]`, so by removing them we make `mpsc` types play nice with drop check. This was previously attempted in [#105243](https://github.com/rust-lang/rust/pull/105243#issuecomment-1337188646) but then [abandoned due to a test failure](https://github.com/rust-lang/rust/pull/105243#issuecomment-1337227970). I've aligned the test with those for `Mutex` and `RwLock`.

Allow redirecting subprocess stdout to our stderr etc. (redux) This is the code from #88561, tidied up, including review suggestions, and with the for-testing-only CI commit removed. FCP for the API completed in #88561. I have made a new MR to facilitate review. The discussion there is very cluttered and the branch is full of changes (in many cases as a result of changes to other Rust stdlib APIs since then). Assuming this MR is approvedl we should close that one. ### Reviewer doing a de novo review Just code review these four commits.. FCP discussion starts here: https://github.com/rust-lang/rust/pull/88561#issuecomment-1640527595 Portability tests: you can see that this branch works on Windows too by looking at the CI results in #88561, which has the same code changes as this branch but with an additional "DO NOT MERGE" commit to make the Windows tests run. ### Reviewer doing an incremental review from some version of #88561 Review the new commits since your last review. I haven't force pushed the branch there. git diff the two branches (eg `git diff 176886197d6..0842b69c219`). You'll see that the only difference is in gitlab CI files. You can also see that *this* MR doesn't touch those files.
2023-09-09std::process (unsupported): Implement From<io::Stdout> etc. for imp::StdioIan Jackson-0/+20
This implementation is wrong. Like the impl for From<File>, it is forced to panic because process::Stdio in unsupported/process.rs doesn't have a suitable variant. The root cause of the problem is that process::Stdio in unsupported/process.rs has any information in it at all. I'm pretty sure that it should just be a unit struct. However, making that build on all platforms is going to be a lot of work, iterating through CI and/or wrestling Docker. I don't think this extra panic is making things significantly worse. For now I have added some TODOs.

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.
