RE: [ft-devel] Re: xorg crashes with freetype2-2.1.10
Hello everyone, I'm back from vacation and have some hints regarding this infamous crash. - First of all, the reason why some pointers have been set to NULL in the latest package is really that: * the functions were _not_ used by the rest of the library, nor exposed through a public API. And I couldn't reasonnably guess what the X.org code was doing * the functions are completely removed in the heap-optimized version of the library. If you want to correct it safely, line 370 of 'src/sfnt/sfdriver.c' should read instead: #ifdef FT_OPTIMIZE_MEMORY 0 /* tt_find_sbit_image */, 0 /* tt_load_sbit_metrics */, #else tt_find_sbit_image, tt_load_sbit_metrics, #endif - The real problem is that the X.org code relies on features that are internal to the library. This is ok as long as its sources are embedded within the X Server (or X Font Server), but breaks when trying to rely on the library installed on the system. There aren't that many solutions, but they do exist: A/ Forget about the optimization, load the glyphs twice and be done with it. B/ Keep a copy of the FreeType sources within X.org, and never use the system-installed version of the library. C/ Ask for a dedicated public API for the problem, which will appear in a later release of the library (e.g. 2.2.0). Do some twisted magic at compile-time: - if the version of FreeType headers used at compile time are 2.2.0, forget about the optimization This is the only way to generate correct code that will never break in the future. By the way, I don't think I'll be able to produce a patch for X.org in the coming weeks !!

Thanks for all your tests, but to really find out the problem we need backtraces, which I was told is not an easy thing with X. We have one in my original report. It has full debugging symbols, and shows exactly where in xorg the symbol is being dereferenced. There are two problems. The one with your backtrace shows that this particular xorg version uses an internal function of FreeType which has changed. I think David T. can answer this better (after returning from his vacation) since he has already written some patches for main applications to avoid FreeType internals. The other problem (reported by James) could be a different bug, probably in the cmap code of FreeType, and for his particular problem I would like to see a backtrace.

Mozilla uses client-side fonts via libXft. The crash in question is in the X server's freetype module which supports server-side fonts. You'll need to use an app which uses the (older) server-side font support to trigger the bug. An easy choice is xfd(1x) with a -fn option. Eg: xfd -fn -adobe-courier-medium-r-normal--0-0-100-100-m-0-iso10646-1 should trigger the bug if you have the freetype module loaded and an entry in a fonts.dir file in your fontpath that points that XLFD to a scalable font. -JimC -- James H.

Re: [ft-devel] Re: xorg crashes with freetype2-2.1.10
If none of those fonts generates a crash, I have to presume that either the X server is not using freetype 2.1.0 for its freetype font loading module or an X font server is in use. Does the directory with that fonts.dir file show up in: xset q and is X's .../modules/fonts/libfreetype.so linked against freetype 2.1.0? (It may be a dynamic link w/ the dlloader, but I presume would have to be a static link using the older elf loader.) I was seeing crashes many months ago and stopped using scalable server-side fonts as a result. I found that I didn't need any given that most of the apps I run now use Xft. At that stage I had a cvs version of freetype installed in /usr/lib. Xorg must have been linking against that rather than the version in the xorg tarfile. That is likely distribution-specific behavior, though. -JimC ___ Freetype-devel mailing list Freetype-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/freetype-devel
Re: [ft-devel] Re: xorg crashes with freetype2-2.1.10
The ChangeLog entry does mention the specific change explicitly: 2005-02-28 David Turner [EMAIL PROTECTED] ... * src/sfnt/sfdriver.c (sfnt_interface) [TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: Don't use `tt_find_sbit_image' and `tt_load_sbit_metrics'. ... So the change is intentional. I just upgraded to stock freetype 2.1.10 (was using cvs-2004-dec-31), went around a few web pages with mozilla-xft, and I don't have crashes. I am using xorg 6.8.2 on linux. How do you trigger the crash?
