Support `#[unix_sigpipe = "inherit\|sig_dfl\|sig_ign"]` on `fn main()` 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. 2022-07-05 19:56:22 +02:00			`#![feature(start)]`

unix_sigpipe: Replace `inherit` with `sig_dfl` in syntax tests The `sig_dfl` variant of the attribute is the most likely variant to be stabilized first, and thus to become the "most allowed" variant of the attribute. Because of this, it is the most appropriate variant to use in syntax tests, because even if the most allowed variant is used, the compiler shall still emit errors if it e.g. is used in the wrong places. 2024-02-09 08:05:32 +01:00			#[unix_sigpipe = "sig_dfl"] //~ error: `unix_sigpipe` attribute can only be used on `fn main()`
