Exa hangs on remote SSH

[koliyo]

I have no idea why this started happening. It has not been a problem before.

But exa now hangs indefinitely when running on a remote SSH connection.

I am using exa 0.9.0, installed via homebrew.

If i run /bin/ls I get expected listing.

But running /usr/local/bin/exa now cause my terminal to hang, and I am even unable to use CTRL-C or CTRL-Z.

Really like exa overall though! Have been using it for some time without issues, but this appeared now for some reason.

Hmm, it also hangs if I try auto-completing in my zsh shell. Not sure if related issue, I do use an alias for exa, ls=exa

[koliyo]

Hmm, this machine is behaving very strangely in general, problems with running CI jobs on it as well. So the exa problem may just be some symptom of a deeper problem.

But still, it is strange that /bin/ls is not affected. I would assume that ls and exa are accessing the same system resources/files.

This could be caused by many things!

Could you try setting the EXA_DEBUG environment variable, to see if it's getting stuck on anything in particular? You can do this with env EXA_DEBUG=1 exa.

Not sure if this is the same issue, but when I mount remote directory with sshfs and sleep my PC, then after wake up exa hangs.
What's interesting is that ls doesn't hang on listing directory where remote dir is mounted, but hangs on listing items inside it.
exa hangs doing either of them.
Attempts to umount and bash tab completion hangs too, so I suspect it's not exa's fault, but some other issue.

Here are outputs for exa v0.9.0 and ls v8.32, where redacted is mounted remote directory
