[X2go-dev] Bug in x2golistsessions with z-shell

[Ralf Schulze]

Hello together.

I stumbled over a bug concerning the resume of sessions with users that
have 'zsh' as their default shell. The problem is the following:

Somewhere during the resume something like 'export HOSTNAME &&
x2golistsessions' is executed. In 'bash' 'export HOSTNAME' sets the
environment variable to the current hostname. In 'zsh' (and probably
other shells, too) this fails leaving an empty HOSTNAME envirtonment
variable.

I suggest to change the perl script x2golistsessions to the following:

#!/usr/bin/perl
use strict;
use Sys::Hostname; # <-- New line

...

my $serv=shift;
if( ! $serv)
{
   #$serv=$ENV{'HOSTNAME'}; # delete this
   $serv = hostname;	    # <-- New line
}
...


This is probably much more robust and works fine here.
