I have seen this bug only with the call: ExternalProgram.cc(start_program):202 Executing 'polkit-auth' '--user' 'root' '--explicit' This call returns "sometimes" a result and "sometimes" not. Calling it on the console everything works correctly ( with and without tty_wrapper) Tested yast version: yast2-core-2.17.25-2.10 I will attach the y2log in order to show the results. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=470645 User lslezak@novell.com added comment https://bugzilla.novell.com/show_bug.cgi?id=470645#c6 --- Comment #6 from Ladislav Slezak 2009-02-04 07:15:09 MST --- Um, I did several hundreds of SCR calls over DBus, all were OK. But I suspect ExternalProgram class from doing something bad. This class is used in both components (.bash_output agent and in tty_wrapper). If I start "date" for several times [*] in tty_wrapper the output is sometimes lost: 189 St úno 4 15:05:11 CET 2009 190 191 St úno 4 15:05:11 CET 2009 192 St úno 4 15:05:12 CET 2009 Here, the 190th line was lost. I have no idea how to debug it, I can't imagine running it 200 times in gdb... I'll check the code more carefully. [*] for num in `seq 1 1000`; do echo -n "$num " && /usr/lib/YaST2/bin/tty_wrapper date; done -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
