Stuck When used

[flaming-archer]

I like polysh very much.
But recently I found polysh is easy to stuck.
The cpu is 100%
When i ctrl + c, then display
suTraceback (most recent call last):

Hi @flaming-archer,

Glad to here you like polysh.

Do you have steps to reproduce this issue ?

I tried connecting to a few hundreds hosts and ran a few commands and had no luck seeing it burn CPU and getting stuck.

Information about your environment like Python version and OS could be helpful too.

Terminal emulator and version would also be interesting.

[flaming-archer]

Python 3.8.10
MacBook Pro (16-inch, 2019) macOS Big sur version 11.6 20G165
Iterm2 Build 3.4.9
Steps:
python3 /xxxx/run.py host1 host2 ...
then do some command like ls cat ..
then stuck.

I doubt whether ssh stable should stuck. For example, when ssh suddenly lost connection or connect need too much time.

Hey @flaming-archer,

I am able to reproduce as similar behaviour on Mac OS. It seems not to happen on my daily Linux OS. I'll try to debug it on my private Mac when I have some time.

FWIF I think there were always issues with polysh on macos. One issue was that apples patched ssh agent was slow and would sometimes randomly fail when connecting to too many hosts at once. CC @Woellchen who maybe remembers more as he actually used this at work.

Hi @shuosiw,

I will try to have another look at it when I have some spare time.
