X Error when starting DDT debugger

Description (last modified by Antoine Martin)

Hi,

I'm trying to run DDT under xpra, but I get the following error:

$ DISPLAY=:100 /home/angelv/ddt/bin/ddt
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  42 (X_SetInputFocus)
  Serial number of failed request:  22
  Current serial number in output stream:  24
$ 

This is in a Ubuntu 11.04 (x86_64) box, running xpra v0.0.7.33. I include below the xpra log, in case it can shed some light into the issue.

Thanks a lot,
Ángel de Vicente

Not sure what the ddt/bin/ddt script does that causes problems, but launching ddt/libexec/ddt.bin works ok. Is that enough to get you going? Or do you really need those bits?

It does some LD_LIBRARY_PATH trickery to include its own copy of shared libraries (qt, GL and others) - this is generally a big no-no, only a proprietary app can get away with nasty hacks like these.

I even managed to crash the whole server by running the server with GDK_SYNCHRONIZE=1 xpra start :7 --no-daemon
here is the gdb backtrace:

The crash comes from their splash screen, here is another way of getting past it:

DDT_NO_SPLASH=1 ./bin/ddt

I really don't know what the splash screen does to crash the Xvfb.

comment:5 Changed 9 years ago by Txibilis

Hi,

the DDT_NO_SPLASH option works on my side as well, and it is quite convenient, so as far as I'm concerned, this is not a problem anymore.

Thanks a lot,
Ángel de Vicente

OK, I would like to try to find what the splash screen does to crash the Xvfb (I even tried Xdummy to see if it would help - no change), but without the source this is going to be difficult so I am closing this ticket for now.

Done some more investigation on this and it looks like some xatoms are mangled or missing causing all calls to XGetWindowAttributes and XGetGeometry to fail.

Now I have a dirty patch which just ignores those windows, this allows one to run ddt without ever seeing the splash screen since we ignore the whole window:

I don't want to merge this, so I'll try to figure out which properties are messed up instead.

comment:9 Changed 9 years ago by Antoine Martin

This is a better fix: we detect that the window is broken in the same place where we normally do it (during setup):

With this in place, the splash screen simply does not show up, and all you get are a few warnings about broken atoms in the logs.

I wished I could figure out why gtk crashes with this window, the first call to get_geometry normally succeeds but the second one fails!?
Looks like something to do with call_synced vs call_asynced and gtk.gdk.flush() - but switching to sync mode crashes..

I will try to get to the bottom of this problem before committing any changes.

r577 causes broken windows to be discarded sooner (almost identical to patch in comment:9)

I no longer have a valid license to test, but just testing with the splash screen and the server no longer dies.

Note: the root cause of the crash probably has not been fixed, so we may need to revisit this.
