Problems with drawing text in 1.3.29

[Damian Dixon]

Hi,

I was attempting to use Wine 1.3.29 (in OpenSUSE 11.4 x86) and because of
issues pulled the source from git last night and still have problems.

I am having performance issues with DrawText (5 odd seconds to draw a simple
string) and the occasional X Error and crash.

The X Error is consistent and is as follows:

fixme:advapi:SetSecurityInfo stub
X Error of failed request:  BadLength (poly request too large or internal
Xlib length error)
  Major opcode of failed request:  151 (RENDER)
  Minor opcode of failed request:  17 (RenderCreateGlyphSet)
  Serial number of failed request:  41091
  Current serial number in output stream:  41571
Process of pid=0023 has terminated

The crash less consistent but is dependent upon the amount of text I attempt
to draw.

The last version I know this worked in was 1.1.39.

I've a few things to still try out before I attempt to create an RBT.

However I would like to know if anyone else is experiencing similar problems
and f they have solved the problem.

Thanks
Damian

1.1.39 is quite old. Can you try regression testing that?
At the least test with 1.2.x and other 1.3.x versions (you can
probably find some earlier binary packages)

Also, this should probably go to wine-users list, and not wine-devel

To get a backtrace and be able to dump some datastructures, run with

WINEDEBUG=+synchronous wine foo.exe

This will bring it into the debugger once the condition happens.

Thanks for the suggestions.

I've narrowed one of the issues down to WineEngGetGlyphOutline
in dlls/gdi32/freetype.c.

The pitch is 6640 and the height is 53003. This means that a buffer of
~335Mb has been allocated and then memset.

This is where the slow down is occurring (because of the memset). I suspect
the resultant crash is also because of this.

I would suggest that limits need to be placed on the maximum pitch and
height.

I do not however believe that this is the root cause just one of the
symptoms.
