3D test doesn't exit

[Achim]

As it seems the 3D test doesn't exit, it seems to run forever.
Attached is a text file with some system information.

Hi, thanks for reporting this.

Can you specify which test it was? (In the UI, the name of the test appears in the title bar at the top of the UI window)

If it's the test that runs glxgears (the test name is graphics/glxgears) then the test does require the user to close the gears program.

I think this could certainly stand to be changed... but can you confirm it is the glxgears test you're referring to?

[Jeff Lane  (bladernr)]

assuming this is glxgears, this could easily be fixed with a bit of shell code to auto close the glxgears window...

that's assuming it works at all. On my system, mesa_utils isn't installed by default, so I never get to see this test :( which is odd... I opened a different bug about that earlier.

[Achim (ach1m)]

Yes it is the test "graphics/glxgears".

If I close the glxgears window I get a message that says:
"Test graphics/glxgears from suite __graphics__ failed. Do you want to report a bug?"
I can choose between "Yes" and "No", If I press "Yes" apport seems to collect some data but no browser window opens.

So I guess glxgears doesn't close cleanly.

[Jeff Lane  (bladernr)]

If you don't mind... you successfully ran glxgears... do you have mesa_utils installed on your Oneiric system?

Did you install mesa_utils manually?

Can you provide the output of apt-cache policy mesa_utils??

I ask because on my fresh Oneiric installation, mesa_utils is not installed at all, and I can't even try running that test, because it depends on mesa_utils being present.

[Achim (ach1m)]

Yes mesa_utils is installed. I installed it manually some time ago.

mesa-utils:
  Installed: 8.0.1+git20110129+d8f7d6b-0ubuntu2
  Candidate: 8.0.1+git20110129+d8f7d6b-0ubuntu2
  Version table:
 *** 8.0.1+git20110129+d8f7d6b-0ubuntu2 0
        500 http://archive.ubuntu.com/ubuntu/ oneiric/universe i386 Packages
        100 /var/lib/dpkg/status

If I close glxgears I get the following error:
XIO: fatal IO error 104 (Connection reset by peer) on X server ":0"
      after 459 requests (459 known processed) with 0 events remaining.

I think that is the reason why the test fails.

[Jeff Lane  (bladernr)]

Yeah, this seems to be the fault of glxgears... happens on Natty too...

Interestingly, on both, if you close the window using the window controls, glxgears and glxheads on both natty and oneiric exit with a 1.

If you do something more creative like this:

kill -2 `pidof glxgears`

you get different exit codes like 131, 129, 147, etc, depending on the signal used to kill glxgears...

Seems like it may be impossible to cleanly exit glxgears :/

[Jeff Lane  (bladernr)]

setting high because this needs to be dealt with before the final freeze

[Jeff Lane  (bladernr)]

Just pushed a branch that simply removes this test from the default test list.

Achim is correct and everything I tried resulted in strange exit codes.

There IS a perfectly simple solution, and that is changing the test description to add:

"Once you see the gears appear and verity that they are moving, press the Escape (ESC) button to close the test."

Pressing Escape will cleanly close glxgears and return a 0 exit status. ANYTHING but pressing escape will result in a non-zero exit.

A second idea would be to wrap glxgears in some shell code to snag the exit status and simply return 0 every time and let the user manually select Yes or No in the checkbox dialog.

However, both of those ideas, while simple to implement, are moot because mesa-utils has been moved out of main and into Universe, so no Oneiric system will have glxgears installed anyway.

Since we don't require installation of packages from Universe for UF testing, the only viable option is to remove the test all-together and the revisit this in P and try to put in a better test.
