High cpu usage

[aylen384]

The application seems to be using 100% cpu on one core.
Maybe a while loop that constantly checks for data or user input? In that case it should use the select call to watch for new data.

It's not caused by checking for data, since blocking socket calls are used for that, running in a thread. More likely there's something going on with Urwid, the TUI library Paracon uses. I'll have a look.

Could you provide some additional info, please? Which operating system and which terminal software? Are there specific situations in which you see this happen? So far I have not been able to reproduce the problem, so more details might help me track it down.

I am using openSUSE Tumbleweed (Linux). I actually packaged paracon for openSUSE: https://build.opensuse.org/package/show/home:dheidler:paracon/paracon See here for the pyham dependencies: https://build.opensuse.org/project/show/home:dheidler:paracon And here for the built RPMs: https://download.opensuse.org/repositories/home:/dheidler:/paracon/openSUSE_Tumbleweed/noarch/ And I'm using alacritty as a terminal.

I was able to reproduce the issue:

1. Start direwolf
2. Start paracon (the AGWPE connection needs to be set up)
3. Stop direwolf while paracon is still running
4. paracon will use 100% of the available cpu time of one core

Thanks, very helpful. I've found the problem.
