# Description
Now we only use `nix 0.28.0`
Achieved by
- updating `ctrlc` to `3.4.4`
- updating `wl-clipboard-rs` to `0.8.1`
- update our own dependency on `nix` from `0.27` to `0.28`
- required fixing uses of `nix::unistd::{tcgetpgrp,tcsetpgrp}`
- now requires an I/O safe file descriptor
- fake one pointing to `libc::STDIN_FILENO` (we were only accessing
`0` previously, dito for fish)
# User-Facing Changes
Better compile times and less to download as source dependencies
# Description / User-Facing Changes
Signals are no longer blocked for child processes launched from both
interactive and non-interactive mode. The only exception is that
`SIGTSTP`, `SIGTTIN`, and `SIGTTOU` remain blocked for child processes
launched only from **interactive** mode. This is to help prevent nushell
from getting into an unrecoverable state, since we don't support
background jobs. Anyways, this fully fixes#9026.
# Other Notes
- Needs Rust version `>= 1.66` for a fix in
`std::process::Command::spawn`, but it looks our current Rust version is
way above this.
- Uses `sigaction` instead of `signal`, since the behavior of `signal`
can apparently differ across systems. Also, the `sigaction` man page
says:
> The sigaction() function supersedes the signal() function, and should
be used in preference.
Additionally, using both `sigaction` and `signal` is not recommended.
Since we were already using `sigaction` in some places (and possibly
some of our dependencies as well), this PR replaces all usages of
`signal`.
# Tests
Might want to wait for #11178 for testing.
# Description
Simplifies `SIGQUIT` protection to a single `signal` ignore system call.
# User-Facing Changes
`SIGQUIT` is no longer blocked if nushell is in non-interactive mode
(signals should not be blocked in non-interactive mode).
Also a breaking API change for `nu_protocol`.
# Tests + Formatting
Should come after #11178 for testing.
# Description
When launching nushell interactively from another shell, the parent
shell usually gives us own our process group and handles restoring
control to itself. However, other programs that do not support job
control expect us to give control of the terminal back to them. This PR
makes it so that we record the initial foreground process group and
restore it when nushell exits. An "exit" can be from the `exit` command,
a panic, or a `SIGTERM` signal.
The changes in `terminal.rs` mostly follow [fish's
example](0874dd6a96/fish-rust/src/common.rs (L1634)).
# User-Facing Changes
Fixes interactions between nushell and other interactive CLI commands
(e.g., VIFM #10015).
# Description
This PR tries to remove ~atty~ is-terminal from the entire code base,
since ~[atty is
unmaintained](https://rustsec.org/advisories/RUSTSEC-2021-0145) and~
[`is_terminal` has been
stabilized](https://blog.rust-lang.org/2023/06/01/Rust-1.70.0.html#isterminal)
in rust 1.70.0.

# Description
Currently, foreground process management is disabled for macOS, since
the original code had issues (see #7068).
This PR re-enables process management on macOS in combination with the
changes from #9693.
# User-Facing Changes
Fixes hang on exit for nested nushells on macOS (issue #9859). Nushell
should now manage processes in the same way on macOS and other unix
systems.
# Description
This reverts #9693 as it lead to CPU hangs. (btw, did the revert by hand
as it couldn't be done automatically. Hopefully I didn't miss anything 😅
)
Fixes#9859

# Description
Fixes a regression from #9681 where nushell will attempt to place itself
into the background or take control of the terminal even in
non-interactive mode.
Using the same
[reference](https://www.gnu.org/software/libc/manual/html_node/Initializing-the-Shell.html)
from #6584:
>A subshell that runs *interactively* has to ensure that it has been
placed in the foreground...
>A subshell that runs *non-interactively* cannot and should not support
job control.
`fish`
[code](54fa1ad6ec/src/reader.cpp (L4862))
also seems to follow this.
This *partially* fixes
[9026](https://github.com/nushell/nushell/issues/9026). That is, nushell
will no longer set the foreground process group in non-interactive mode.
# Description
Due to a typo? in the
[reference](https://www.gnu.org/software/libc/manual/html_node/Initializing-the-Shell.html)
used to implement SIGTTIN handling, nushell will crash when being sent
to the background from within another shell.
For example, currently in bash:
```bash
$ nu -n &
[1] 176058
$ ERROR: failed to SIGTTIN ourselves
[1]+ Exit 1 nu -n
$
```
Now fixed:
```bash
$ nu -n &
[1] 178788
$ jobs
[1]+ Stopped nu -n
$
```
For further reference, this is how
[fish](493cbeb84c/src/reader.cpp (L2571))
does it.
# User-Facing Changes
Bug fix only -- users should now be able to send nushell to the
background.
# Description
Until we bump our minimal Rust version to `1.70.0` we can't use
`std::io::IsTerminal`. The crate `is-terminal` (depending on `rustix` or
`windows-sys`) can provide the same.
Get's rid of the dependency on the outdated `atty` crate.
We already transitively depend on it (e.g. through `miette`)
As soon as we reach the new Rust version we can supersede this with
@nibon7's #9550
