Expected Behavior

piping just works like in other shells

Current Behavior

pipes work for some commands but hangs shell for others. ctrl z makes the job background and returns to zonsh.
jobs return:
[1]+ running: echo hai | grep hai (149404)
fg doesnt do anything if grep but opens an empty window if it was a command piped to less and pressing q quits like in normal less window

Traceback (if applicable)

no traceback as shell hangs

Steps to Reproduce

following commands doesnt work
cat /etc/resolv.conf | less
echo hai | grep hai

following works
ls | grep filename
more textfile | grep string
I'm using arch linux

> xonsh -V
xonsh/0.10.0

cat /etc/resolv.conf | more freezes shell completely. ctrl +z or c doesnt work

Hey @aspieln3r -- thanks for reporting! Can you try upgrading to 0.10.1?
I'm also on arch and can't reproduce these hangs

[aspieln3r]

I'm already using latest on community. Will update once 0.10.1 hits repo

[anki-code]

hi @aspieln3r! I also can't reproduce this.
Could you please run bash then run xonsh --no-rc and test the command.
If it works test your RC-file line by line to catch the error.

[aspieln3r]

@anki-code I tried it and everything works well if I disable xontrib load coreutils. That also explains why I got issue with only cat and echo. Issue is present in 0.10.1 too

[anki-code]

@aspieln3r why you need coreutils xontrib on Arch? This xontrib mostly for Windows users.

[aspieln3r]

From https://xon.sh/xontribs.html#coreutils

In many cases, these may have a lower performance overhead than the posix command line utility with the same name. This is because these tools avoid the need for a full subprocess call. Additionally, these tools are cross-platform.

So I thought it wouldn't hurt using that.

I think this affects all aliases for this matter.

which ls | grep ls

also hangs.

❯ xonsh --no-rc

                                                               Welcome to the xonsh shell 0.12.4

                                                             ~ Tab completion in Alderaan places ~

# ...

joerg@turingmachine ~ master $ def command(args, stdin, stdout):
..............................     print("foo", file=stdout)
..............................
joerg@turingmachine ~ master $ aliases["command"] = command
joerg@turingmachine ~master $ del command
joerg@turingmachine ~master $ command | grep foo # this will hang until one presses `ctrl-c`

[Mic92]

It seems that even pipeliner hangs for me:

turingmachine in dotfiles on  master via 🐍 v3.9.12 via ❄️  impure (nix-shell)
❯ xontrib load pipeliner

turingmachine in dotfiles on  master via 🐍 v3.9.12 via ❄️  impure (nix-shell)
❯ ls -1 / | pl "line + ' is here'" | head -n 3

@Mic92 Could you please try setting $THREAD_SUBPROCS=True and then running those commands?

[Mic92]

Sorry. Stopped using xonsh.
