|

- [Change equality of higher ranked types to not rely on subtyping](https://github.com/rust-lang/rust/pull/118247)
|
||||
- [When called, additionally check bounds on normalized function return type](https://github.com/rust-lang/rust/pull/118882)
|
||||
- [Expand coverage for `arithmetic_overflow` lint](https://github.com/rust-lang/rust/pull/119432/)
|
||||
- [Fix detection of potential interior mutability in `const` initializers](https://github.com/rust-lang/rust/issues/121250)
|
||||
This code was accidentally accepted. The fix can break generic code that borrows a value of unknown type,
|
||||
as there is currently no way to declare "this type has no interior mutability". In the future, stabilizing
|
||||
the [`Freeze` trait](https://github.com/rust-lang/rust/issues/121675) will allow proper support for such code.

# `on-broken-pipe`

|
||||
--------------------
|
||||
|
||||
The tracking issue for this feature is: [#97889]
|
||||
|
||||
Note: The ui for this feature was previously an attribute named `#[unix_sigpipe = "..."]`.
|
||||
|
||||
[#97889]: https://github.com/rust-lang/rust/issues/97889

|

|
||||
|
||||
## Overview
|
||||
|
||||
The `-Zon-broken-pipe=...` compiler flag can be used to specify how libstd shall setup `SIGPIPE` on Unix platforms before invoking `fn main()`. This flag is ignored on non-Unix targets. The flag can be used with three different values or be omitted entirely. It affects `SIGPIPE` before `fn main()` and before children get `exec()`'ed:
|
||||
|
||||
| Compiler flag | `SIGPIPE` before `fn main()` | `SIGPIPE` before child `exec()` |
|
||||
|----------------------------|------------------------------|---------------------------------|
|
||||
| not used | `SIG_IGN` | `SIG_DFL` |
|
||||
| `-Zon-broken-pipe=kill` | `SIG_DFL` | not touched |
|
||||
| `-Zon-broken-pipe=error` | `SIG_IGN` | not touched |
|
||||
| `-Zon-broken-pipe=inherit` | not touched | not touched |
|
||||
|
||||
|
||||
## `-Zon-broken-pipe` not used
|
||||
|
||||
If `-Zon-broken-pipe` is not used, libstd will behave in the manner it has since 2014, before Rust 1.0. `SIGPIPE` will be set to `SIG_IGN` before `fn main()` and result in `EPIPE` errors which are converted to `std::io::ErrorKind::BrokenPipe`.
|
||||
|
||||
When spawning child processes, `SIGPIPE` will be set to `SIG_DFL` before doing the underlying `exec()` syscall.
|
||||
|
||||
|
||||
## `-Zon-broken-pipe=kill`
|
||||
|
||||
Set the `SIGPIPE` handler to `SIG_DFL` before invoking `fn main()`. This will result in your program getting killed if it tries to write to a closed pipe. This is normally what you want if your program produces textual output.
|
||||
|
||||
When spawning child processes, `SIGPIPE` will not be touched. This normally means child processes inherit `SIG_DFL` for `SIGPIPE`.
|
||||
|
||||
### Example
|
||||
|
||||
```rust,no_run
|
||||
fn main() {
|
||||
loop {
|
||||
println!("hello world");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```console
|
||||
$ rustc -Zon-broken-pipe=kill main.rs
|
||||
$ ./main | head -n1
|
||||
hello world
|
||||
```
|
||||
|
||||
## `-Zon-broken-pipe=error`
|
||||
|
||||
Set the `SIGPIPE` handler to `SIG_IGN` before invoking `fn main()`. This will result in `ErrorKind::BrokenPipe` errors if you program tries to write to a closed pipe. This is normally what you want if you for example write socket servers, socket clients, or pipe peers.
|
||||
|
||||
When spawning child processes, `SIGPIPE` will not be touched. This normally means child processes inherit `SIG_IGN` for `SIGPIPE`.
|
||||
|
||||
### Example
|
||||
|
||||
```rust,no_run
|
||||
fn main() {
|
||||
loop {
|
||||
println!("hello world");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```console
|
||||
$ rustc -Zon-broken-pipe=error main.rs
|
||||
$ ./main | head -n1
|
||||
hello world
|
||||
thread 'main' panicked at library/std/src/io/stdio.rs:1118:9:
|
||||
failed printing to stdout: Broken pipe (os error 32)
|
||||
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
|
||||
```
|
||||
|
||||
## `-Zon-broken-pipe=inherit`
|
||||
|
||||
Leave `SIGPIPE` untouched before entering `fn main()`. Unless the parent process has changed the default `SIGPIPE` handler from `SIG_DFL` to something else, this will behave the same as `-Zon-broken-pipe=kill`.
|
||||
|
||||
When spawning child processes, `SIGPIPE` will not be touched. This normally means child processes inherit `SIG_DFL` for `SIGPIPE`.

# `unix_sigpipe`
|
||||
|
||||
The tracking issue for this feature is: [#97889]
|
||||
|
||||
[#97889]: https://github.com/rust-lang/rust/issues/97889
|
||||
|
||||
---
|
||||
|
||||
The `#[unix_sigpipe = "..."]` attribute on `fn main()` can be used to specify how libstd shall setup `SIGPIPE` on Unix platforms before invoking `fn main()`. This attribute is ignored on non-Unix targets. There are three variants:
|
||||
* `#[unix_sigpipe = "inherit"]`
|
||||
* `#[unix_sigpipe = "sig_dfl"]`
|
||||
* `#[unix_sigpipe = "sig_ign"]`
|
||||
|
||||
## `#[unix_sigpipe = "inherit"]`
|
||||
|
||||
Leave `SIGPIPE` untouched before entering `fn main()`. Unless the parent process has changed the default `SIGPIPE` handler from `SIG_DFL` to something else, this will behave the same as `#[unix_sigpipe = "sig_dfl"]`.
|
||||
|
||||
## `#[unix_sigpipe = "sig_dfl"]`
|
||||
|
||||
Set the `SIGPIPE` handler to `SIG_DFL`. This will result in your program getting killed if it tries to write to a closed pipe. This is normally what you want if your program produces textual output.
|
||||
|
||||
### Example
|
||||
|
||||
```rust,no_run
|
||||
#![feature(unix_sigpipe)]
|
||||
#[unix_sigpipe = "sig_dfl"]
|
||||
fn main() { loop { println!("hello world"); } }
|
||||
```
|
||||
|
||||
```bash
|
||||
% ./main | head -n 1
|
||||
hello world
|
||||
```
|
||||
|
||||
## `#[unix_sigpipe = "sig_ign"]`
|
||||
|
||||
Set the `SIGPIPE` handler to `SIG_IGN` before invoking `fn main()`. This will result in `ErrorKind::BrokenPipe` errors if you program tries to write to a closed pipe. This is normally what you want if you for example write socket servers, socket clients, or pipe peers.
|
||||
|
||||
This is what libstd has done by default since 2014. (However, see the note on child processes below.)
|
||||
|
||||
### Example
|
||||
|
||||
```rust,no_run
|
||||
#![feature(unix_sigpipe)]
|
||||
#[unix_sigpipe = "sig_ign"]
|
||||
fn main() { loop { println!("hello world"); } }
|
||||
```
|
||||
|
||||
```bash
|
||||
% ./main | head -n 1
|
||||
hello world
|
||||

|
||||
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
|
||||
```
|
||||
|
||||
### Note on child processes
|
||||
|
||||
When spawning child processes, the legacy Rust behavior if `#[unix_sigpipe]` is not specified is to
|
||||
reset `SIGPIPE` to `SIG_DFL`.
|
||||
|
||||
If `#[unix_sigpipe = "..."]` is specified, no matter what its value is, the signal disposition of
|
||||
`SIGPIPE` is no longer reset. This means that the child inherits the parent's `SIGPIPE` behavior.
