When using `process::Command` on Windows, environment variable names must be case-preserving but case-insensitive
When using `Command` to set the environment variables, the key should be compared as uppercase Unicode but when set it should preserve the original case.
Fixes#85242
Use HTTPS links where possible
While looking at #86583, I wondered how many other (insecure) HTTP links were in `rustc`. This changes most other `http` links to `https`. While most of the links are in comments or documentation, there are a few other HTTP links that are used by CI that are changed to HTTPS.
Notes:
- I didn't change any to or in licences
- Some links don't support HTTPS :(
- Some `http` links were dead, in those cases I upgraded them to their new places (all of which used HTTPS)
Closes#73125
This is in pursuance of
Issue #73127 Consider adding #[must_use] to std::process::ExitStatus
In
MR #81452 Add #[must_use] to [...] process::ExitStatus
we concluded that the existing arrangements in are too awkward
so adding that #[must_use] is blocked on improving the ergonomics.
I wrote a mini-RFC-style discusion of the approach in
