[ros-dev] Debug log problems

[Aleksey Bragin]

Hello,
it's time for my periodical rant about debug log mess again. The example 
below is made using latest VirtualBox 3.

Suggestions and questions:

1. usbohci - it's left on intentionally to better aid debugging?
Allright, however I think these lines
(/srv/buildbot_cmake/full_cmake/build/drivers/usb/usbohci/hardware.cpp:1199) 
Waiting 0 milliseconds for port power up 
(/srv/buildbot_cmake/full_cmake/build/drivers/usb/usbohci/hardware.cpp:1145) 
Enabling status change
repeated 8 times is a little bit too much.

Same about libusb listing statuses of all ports. Which goes on yet 
another time with EHCI controller.

2. What are these lines? Repeated 14 times
(/srv/buildbot_cmake/full_cmake/build/ntoskrnl/mm/ARM3/sysldr.c:2959) 
ZwOpenFile failed with status 0xc000003a

3. What happened to the floppy driver?
(/srv/buildbot_cmake/full_cmake/build/ntoskrnl/io/iomgr/driver.c:1579) 
'\Driver\FLOPPY' initialization failed, status (0xc000000e)
(/srv/buildbot_cmake/full_cmake/build/ntoskrnl/io/iomgr/driver.c:61) 
Deleting driver object '\Driver\FLOPPY'
(/srv/buildbot_cmake/full_cmake/build/ntoskrnl/io/iomgr/driver.c:87) 
HACK: Not unloading the driver image due to critical bugs!
(/srv/buildbot_cmake/full_cmake/build/ntoskrnl/io/iomgr/driver.c:1961) 
IopInitializeDriver() failed (Status c000000e)
(/srv/buildbot_cmake/full_cmake/build/ntoskrnl/mm/ARM3/sysldr.c:935) 
Leaking driver: floppy.sys

Fix it? Don't enable it in trunk builds if it's buggy and not fixed?

4. These lines repeated 20 times.
(/srv/buildbot_cmake/full_cmake/build/dll/ntdll/ldr/ldrapi.c:811) 
NtCreateSection() failed (Status 0xc0000022).
Why creating section in LdrpVerifyImageMatchesChecksum() failes now?

5. Win32 stage.
(/srv/buildbot_cmake/full_cmake/build/win32ss/user/ntuser/winsta.c:208) 
err: Invalid window station handle
(/srv/buildbot_cmake/full_cmake/build/win32ss/user/ntuser/ntuser.c:161) 
err: Enter NtUserInitialize(0, 00000000, 00000000)
(/srv/buildbot_cmake/full_cmake/build/win32ss/user/ntuser/display.c:79) 
err: InitDisplayDriver
(\Device\Video0, \Registry\Machine\System\CurrentControlSet\Hardware 
Profiles\Current\System\CurrentControlSet\Services\VBE\Device0);

What happens here? It's a normal bootup, everyone should see this. Why 
is invalid window station handle being passed, why do we need 
NtUserInitialize to produce ERR debug print, along with 
InitDisplayDriver. Are those errors? If not, then why the hell are they 
being printed? If yes, then I don't see any info about actual errors.

6. 
(/srv/buildbot_cmake/full_cmake/build/win32ss/user/ntuser/window.c:2416) 
err: DestroyWindow AOW
AOW? ORLY?

7. MASSIVE portcls spam. I won't even count lines.
(/srv/buildbot_cmake/full_cmake/build/drivers/wdm/audio/backpln/portcls/undoc.cpp:281) 
Calling Node 16 MajorTarget B01EF750 MinorTarget 00000000 PropertySet 
{45ffaaa0-6e1b-11d0-bcf2-444553540000} PropertyId 4 PropertyFlags 
10000200 InstanceSize 0 ValueSize 40 Handler FB24E58A PropertyRequest 
FF55B5F8 PropertyItemFlags 203 PropertyItemId 4
A few pages of that stuff. Is it really useful for everyone, including 
automated testing systems?

8. A work queue deadlock. Not a good thing at all
(/srv/buildbot_cmake/full_cmake/build/ntoskrnl/ex/work.c:351) EX: Work 
Queue Deadlock detected: 1 
(/srv/buildbot_cmake/full_cmake/build/ntoskrnl/ex/work.c:353) Dynamic 
threads queued 2

9. ???

All that resulted from my desire to just compare logs attached to the 
bug report. New log is totally unreadable, I had to spend time figuring 
out where actually that Live Essentials app was started, what problems 
it shows, etc.


Best regards,
Aleksey.
