driconf doesn't run; there is a python error
Last modified: 2009-05-11 02:22:25 EDT
Description of problem: When I run driconf from the command line, the window never appears. Instead, a python error message is generated. Version-Release number of selected component (if applicable): 0.9.1-8.fc10 How reproducible: Happens every time that I run driconf. Steps to Reproduce: 1. run driconf from the command line Actual results: No configuration window appears. The following error message appears in the terminal where the driconf command was entered: Traceback (most recent call last): File "/usr/bin/driconf", line 28, in <module> driconf.main() File "/usr/lib/python2.5/site-packages/driconf.py", line 142, in main simpleui.start(configList) File "/usr/lib/python2.5/site-packages/driconf_simpleui.py", line 871, in start mainWindow = MainWindow(configList) File "/usr/lib/python2.5/site-packages/driconf_simpleui.py", line 522, in __init__ self.selectScreen(0) File "/usr/lib/python2.5/site-packages/driconf_simpleui.py", line 607, in selectScreen self.selectApp(self.deviceConfig.apps[1]) File "/usr/lib/python2.5/site-packages/driconf_simpleui.py", line 643, in selectApp self.appPage = AppPage (self.driver, app) File "/usr/lib/python2.5/site-packages/driconf_simpleui.py", line 347, in __init__ self.refreshOptions() File "/usr/lib/python2.5/site-packages/driconf_simpleui.py", line 370, in refreshOptions lineWrap(opt.getDesc([lang]).text), sectI, optI]) File "/usr/lib/python2.5/site-packages/driconf_simpleui.py", line 271, in lineWrap head, tail = head + tail[:i] + '\n', tail[j:] UnboundLocalError: local variable 'j' referenced before assignment Expected results: A window should appear that configures the DRI. Additional info: When I first installed driconf, the window would appear when I run it from the GNOME menu. I'm not sure what happened that stopped it from running.
I can't seem to duplcate this here. ;( Is there any output from 'rpm -V driconf' ? Can you pinpoint when it started failing? Is there anything that happened around that time? some update? changes you made?
Unfortunately, I'm not sure what happened when started it to fail. I ran 'rpm -V driconf' command and it generated no output. However, if I insert the line "j=i" at line 260 of /usr/lib/python2.5/site-packages/driconf_simpleui.py, the GUI comes up. (This patch was mentioned in the referenced Gentoo bug report.) Looking at the code, I think I understand why there is an error. The variable j is evaluated before it may have been assigned to (depending on the flow of control).
OK, I believe that I have a repeatable procedure to generate the bug. 1) Delete ~/.drirc (or rename it to something else). 2) Run driconf. A pop-up will appear which informs the user that a new DRI Configuration file has been created. 3) Click on the triangle next to the text "Application Settings". This causes the area section of the driconf window to grow. There is an Add button and some other greyed out controls. 4) Click on the Add button. An Add Application pop-up appears. 5) Enter the name and executable of a GL application and then click OK. At this point, you see the following error in the Terminal if you started driconf from a command line: UnboundLocalError: local variable 'j' referenced before assignment 6) Click on the Close button. The driconf window disappears and the program terminates. 7) Try to run driconf again from the command line. The window never appears and the program terminates with the same error message.
Yeah, looks like... It's odd that it never showed up here before. Anyhow, can you try this build: http://koji.fedoraproject.org/koji/taskinfo?taskID=1102462 Does it solve the issue for you?
Yes, this build fixes the problem. I no longer get any python errors when running driconf.
I'be pushed out an update for F10 for this. It should push out on the next push. Thanks for this bug!
This should be all done. Closing now. Thanks again for the bug report.
