[Sshpass-devel] tcgetpgrp() fails in scp -> missing progress bar

[Hans M. <han...@gm...>]

Hello,
"sshpass ... scp ..." doesn't display a progress bar as scp normally does.
I digged in scp code and found the following:

static int
can_output(void)
{
return (getpgrp() == tcgetpgrp(STDOUT_FILENO));
}

The tcgetpgrp call returns -1, if scp is called via sshpass.

I tried a bit hacking in sshpass without success. Without a call of setsid() in the child fork in sshpass, the tcgetpgrp call in the child works as it should, but that fails sshpass entering the password.

As I don't know how theses terminals work in much detail, I am not able to find a solution to this.
I would appreciate it if someone with deeper knowledge fixes this.

I also added this to the bugtracker:

Best regards
