IE Agent crashing on Windows XP for version 2.11

braincracking · April 26, 2013, 10:51am

Hi

I recently upgraded WPT to version 2.11 and since then I have the IE tests (with wptdriver) that keeps being stopped by the Windows DEP (Data Execution Prevention).
I disabled it, IE is crashing.
I modified it to add IE and all agents .exe into the whitelist and I still have the warnings

Other browsers are fine.
It used to work with urlBlast
I’m running it on Windows XP, lastest windows upgrades are made

Did someone encoutered this problem, is there a fix ?

pmeenan · April 26, 2013, 10:55am

I haven’t seen the issue but I also haven’t been using wptdriver on XP for IE much. When are you seeing the DEP warning? Right at launch or in the middle of a test?

braincracking · April 26, 2013, 12:47pm

at launch, before going to the site.
Note that sometimes, the page is displayed

pmeenan · April 27, 2013, 1:32pm

I’ll try to reproduce it - IE 8, Windows XP 32-bit, VM Ware guest, wptdriver? What is the V icon (think it’s VNC but want to be sure)?

Thanks,

-Pat

braincracking · April 29, 2013, 9:41am

yes, that’s VNC
It’s wptdriver, note that the problem does not occur on the same machine with the old urlBlast exe.

braincracking · May 10, 2013, 7:53am

did you had the opportunity to test ?

pmeenan · May 10, 2013, 1:23pm

Yes, sorry for not following up. I’ve been running wptdriver with IE in every config I can manage and can’t seem to reproduce the crash. I’ll start releasing debug builds along with the release ones (next one will be a couple of days) and then that should at least help track it down.

pmeenan · May 10, 2013, 4:45pm

ok, I just did an update to the agents and also did a debug build of them (will try to do that regularly). The debug build is available here: http://www.webpagetest.org/releases/debug/

If you download debugview and run it while the agent is running it should spew all sorts of information about what it is doing: DebugView - Windows Sysinternals | Microsoft Docs

braincracking · May 13, 2013, 2:40pm

I copied / pasted all the files I found in the 2 archives in my agent folder. I run a triple test on IE, and here are the logs in debugView :

[2208] [Pagetest] ***** CIEHook::SetSite
[2208] [Pagetest] - Not hooking, wptdriver test is active
[2888] [Pagetest] ***** CIEHook::SetSite
[2888] [Pagetest] - Not hooking, wptdriver test is active
[3608] [Pagetest] ***** CIEHook::SetSite
[3608] [Pagetest] - Not hooking, wptdriver test is active

pmeenan · May 14, 2013, 12:22pm

Are you sure you grabbed the debug versions of wptdriver.exe and wpthook.dll and that the agent wasn’t running when you tried to update? Those messages are from the debug build of pagetest.dll but it isn’t active because the test is being run by wptdriver.

braincracking · May 14, 2013, 2:56pm

I quit wptdriver before copying the files into the agent/ folder, and reboot the OS

Now I have only those logs for 2 triple tests :
[3108] [Pagetest] ***** CIEHook::SetSite
[3656] [Pagetest] ***** CIEHook::SetSite
[948] [Pagetest] ***** CIEHook::SetSite
[3256] [Pagetest] ***** CIEHook::SetSite
[3740] [Pagetest] ***** CIEHook::SetSite
[3936] [Pagetest] ***** CIEHook::SetSite

Not sure it better helps, or maybe I did something wrong again ?

pmeenan · May 16, 2013, 2:28pm

Even without running any tests, just by running wptdriver you should see something like:

I downloaded the wptdriver-debug-109.zip version, and it seems you updated at least one file (different size when I copied it).
Now in the debugger I see the trace you are showing to me, however traces stop being that verbose before the first test

I think the auto update is overwriting the files, because I see that the files sizes have changed. How can I disable it ?

Go into work/update on your server and rename wptupdate.ini and update.ini

Hi Pat,

Any updates on this? I’m also getting the same IE crash and debug log shows the same thing.

Thanks,
Vicky

pmeenan · June 5, 2013, 9:23pm

No, I’ll see if I can add some extra instrumentation to the hook installing code to see if we can get some more details. That is the point where we inject the instrumentation DLL into the browser process so it’s certainly a risky bit of code but I haven’t seen it crash.

pmeenan · June 6, 2013, 8:29pm

ok, I changed some things that could possibly be going wrong around the code injection and also added a bunch more instrumentation in case it’s still crashing: http://www.webpagetest.org/releases/debug/ (grab the 115 release). If that works then you can just grab the latest build from the WPT server: https://sites.google.com/a/webpagetest.org/docs/private-instances#TOC-Updating-Test-Agents

If it is still crashing, please upload another log and hopefully it gets us closer to the cause.

braincracking · June 26, 2013, 4:09pm

Sorry for my long absence.

The debug version (116) works fine, thanks !
I updated the agents on the server with your latest versions

Many thanks
