Description (last modified by zaytsev) (diff)
Hello world :-)
I noticed recently that mc 4.8.26 on FreeBSD 12.2-RELEASE hangs on start sometimes with zsh. No rule when it happens. I need to kill -9 that process. When -b (no subshell) is provided then mc starts with no problem.
I found that common problem over the internets and -b as temporary workaround. I did not find that issue repoted here so here it goes :-)
Best regards :-)

What reply do you expect? You just ignored all written in NewTicket page. I'm not FreeBSD used therefore bugreport like "4.8.26 on FreeBSD 12.2-RELEASE hangs on start" is useless for me.
-b is "no color". "No subshell" is -u. What do you mean exactly?

Take a look at:

Looks like a common problem.
My mistake, its -u, thanks :-)

What's your shell? Does this happen on 4.8.25 or not?
We've had reports that persistent subshell buffer introduced in 4.8.26 somehow causes random hangs on zsh, but I think most FreeBSD people use tcsh and I think that our persistent subshell buffer implementation simply doesn't work on tcsh...
I wonder what should now happen on tcsh with the new patch, old behaviour or no subshell?

Thanks for you reply zaytsev :-)
Unfortunately I am using ZSH (version 5.8).
I found previous version mc 4.8.24 in my packages cache I will use that one for a while and let you know just to confirm.. that hanging on start showed up recently I am not sure when exactly :-)
What I can see is only a single blue background character in the top right corner of the terminal when the mc hangs. If you can hint me how can I search/debug further please let me know so I can provide more information :-)
