Bug#253: ONMainWindow::closeEvent: If statement depends on uninitialised value.
by Heinrich Schuchardt 28 Jun '13

28 Jun '13

Package: x2goclient Version: 4.0.1.0 Severity: normal Dear maintainer, if in ONMainWindow::ONMainWindow parseParameter(args[i]) fails, close() is called generating a QCLoseEvent. Up to this point variable trayNoclose has not been initialized. Hence in ONMainWindow::closeEvent an unitialised variable trayNoclose is used in statement if (trayNoclose && !brokerMode). Due to initialization brokerMode=false. Obviously the behavior of closeEvent() is undefined. Furthermore in ONMainWindow::closeClient() decisions are based on unitialized variables trayIcon, and useLdap. Please, initialize at least these variables before calling close(). Example: valgrind x2goclient --leak-check=full (--leak-check=full is an illegal parameter for x2goclient) results in: ==7660== Conditional jump or move depends on uninitialised value(s) ==7660== at 0x468D1C: ONMainWindow::closeEvent(QCloseEvent*) (onmainwindow.cpp:1415) Best regards Heinrich Schuchardt

The answer is a permanent yes. Let us not run your clone and upstream X2Go Client too much out of sync. I do not have the time to go through the commits on your clone of X2Go Client, so I rely on you rebasing your patches against git master on code.x2go.org and sending those changes as patches to X2Go BTS. Thanks!

Bug#251: User x2goclient expected, but user x2gothinclient established
by Stephan Wagner 27 Jun '13

27 Jun '13

Package: x2gothinclient Version: 1.0.1.8-0 A user "x2gothinclient" is established in the TCE- environment, but /usr/sbin/x2gothinclientd expects the user "x2goclient", with its home directory at /home/x2goclient. Therefore /usr/bin/x2goclient will not start, leaving the user in front of a black screen. Intruducing the user 'x2goclient' solved the problem.

Please give us some feedback on the questions below: o do you manipulate the SSH port in the global X2Go Client configuration (Windows Registry folder ,,settings'')? o or do you manipulate the SSH port in the session profile? o (I presume a yes for first of the two questions above) Neither am I getting clean the setup you have. o is the VBox VM your X2Go Server? o or your X2Go Client? I hope to get your problem fixed with the next X2Go Client release, so a quick response is appreciated.
