Is this a flaky test or consistently failing?

What you mean? It fails all the time the same way.

Is this new in 1.1.9?

I have no idea. Just first time finished my package with slirp4netns.

What's your OS?

Linux/x86_64 with python 3.8.8.

What's your distro and kernel version?

AkihiroSuda commented 3 years ago

If you run echo 'badjson' | ncat -U $apisocket manually, what does happen? I guess ncat binary on your host might lack support for -U flag.

What's your distro and kernel version?

My own fedora rawhide based with tons of bugs fixed ..

If you run echo 'badjson' | ncat -U $apisocket manually, what does happen? I guess ncat binary on your host might lack support for -U flag.

Is it anything what I can do to help diagnose that issue? I just tested 1.1.10 and test suite still is failing

Is the issue reproducible with any well-known and publicly available distro?

I have no idea. I'm using my own distribution and I don't think that distribution is here relevant :) Just in case I'm using ncat from nmap 7.91.

kloczek commented 3 years ago

Just tested ne version ad test suite still is failing. May I ask which ncat you are using?
