2023-11-24Rollup merge of #118060 - ChrisDenton:abs-device-path, r=thomccMatthias Krüger-1/+1
Use an absolute path to the NUL device While a bare "NUL" *should* be redirected to the NUL device, especially in this simple case, let's be explicit that we aren't opening a file called "NUL" and instead open it directly. This will also set a good example for people copying std code. r? libs

2023-09-09Auto merge of #114590 - ijackson:stdio-stdio-2, r=dtolnaybors-10/+25
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.

2023-08-25Added option to set ProcThreadAttributes for Windows processesMichael van Straten-2/+110
This implements the ability to add arbitrary attributes to a command on Windows targets using a new `raw_attribute` method on the [`CommandExt`](https://doc.rust-lang.org/stable/std/os/windows/process/trait.CommandExt.html) trait. Setting these attributes provides extended configuration options for Windows processes. Co-authored-by: Tyler Ruckinger <t.ruckinger@gmail.com>
2023-08-08Rollup merge of #106425 - ijackson:exit-status-default, r=dtolnayMatthias Krüger-1/+1
Make ExitStatus implement Default And, necessarily, make it inhabited even on platforms without processes. I noticed while preparing https://github.com/rust-lang/rfcs/pull/3362 that there was no way for anyone to construct an `ExitStatus`. This would be insta-stable so needs an FCP.

2023-03-21Rollup merge of #96391 - ChrisDenton:command-non-verbatim, r=joshtriplettMatthias Krüger-8/+4
Windows: make `Command` prefer non-verbatim paths When spawning Commands, the path we use can end up being queried using `env::current_exe` (or the equivalent in other languages). Not all applications handle these paths properly therefore we should have a stronger preference for non-verbatim paths when spawning processes.
2022-12-11Implement blocking outputAyush Singh-0/+5
This allows decoupling `Command::spawn` and `Command::output`. This is useful for targets which do support launching programs in blocking mode but do not support multitasking (Eg: UEFI). This was originally conceived when working on https://github.com/rust-lang/rust/pull/100316 Signed-off-by: Ayush Singh <ayushsingh1325@gmail.com>

2022-02-09Rollup merge of #93445 - yaahc:exitcode-constructor, r=dtolnayYuki Okushi-0/+6
Add From<u8> for ExitCode This should cover a mostly cross-platform subset of supported exit codes. We decided to stick with `u8` initially since its the common subset between all platforms that we support (excluding wasm which I think only works with `true` or `false`). Posix is supposed to take i32s, but in practice many unix platforms mask out all but the low 8 bits or in some cases the 8-15th bits. Windows takes a u32 instead of an i32. Bourne-compatible shells also report signals as exitcode 128 + `signal_no`, so there's some ambiguity there when returning exit codes > 127, but it is possible to disambiguate them on the other side so we decided against restricting the possible codes further than to `u8`. ## Related - Detailed analysis of exit code support on various platforms: https://internals.rust-lang.org/t/mini-pre-rfc-redesigning-process-exitstatus/5426 - https://github.com/rust-lang/rust/issues/48711 - https://github.com/rust-lang/rust/issues/43301 - https://rust-lang.zulipchat.com/#narrow/stream/219381-t-libs/topic/Termination.2FExit.20Status.20Stabilization

Use `into_raw_handle()` rather than `into_inner()` to completely consume a `Handle` without dropping its contained handle.

Introduce `OwnedFd` and `BorrowedFd`, and the `AsFd` trait, and implementations of `AsFd`, `From<OwnedFd>` and `From<T> for OwnedFd` for relevant types, along with Windows counterparts for handles and sockets.
