[Lazarus] Need testers (gtk2)
Hi, I've commited an important patch today (r 27829) , about gtk2 main loop iterations. Now it uses g_main_context instead of g_main which is deprecated from gtk2-2.2. This patch improves main loop, but also now PostMessage() works fine for messages from another threads. *** Gtk2 Laz/LCL must be build with -dUSE_GTK_MAIN_CONTEXT_ITERATION *** to get this new code work. If you find any issues about it, please open it's # at bugtracker. After while I'll set USE_GTK_MAIN_CONTEXT_ITERATION as default, so -d won't be needed anymore. I've tested under: Fedora 3 (gtk2-2.12), Fedora 13 (gtk2-2.20), Ubuntu 10.4 64bit (gtk2-2.20). Gtk2 version isn't important here, but glib2 version is, so if you open any issue about main loop problems, please provide next informations: 1.Linux distribution version + 32 or 64 bit 2.Gtk2 version 3.Glib2 version. 4.Provide an simple example where I can reproduce your problem. thanks. thanks zeljko -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

In my short tests it works well. I didn't notice difference for older versions. I will try PostMessage later. I just happened to debug a GTK2 program. It is the thtmlport package from CCR. It looks like a useful package but it crashes with GTK2. This bug seems to be extremely difficult to find. It shows this: (lazarus:2791): Gdk-CRITICAL **: gdk_window_get_state: assertion `GDK_IS_WINDOW (window)' failed [DBGTGT] Gdk-ERROR **: The program 'framedem' received an X Window System error. [DBGTGT] This probably reflects a bug in the program. [DBGTGT] The error was 'BadMatch (invalid parameter attributes)'. [DBGTGT] (Details: serial 2256 error_code 8 request_code 62 minor_code 0) [DBGTGT] (Note to programmers: normally, X errors are reported asynchronously; [DBGTGT]that is, you will receive the error a while after causing it. [DBGTGT]To debug your program, run it with the --sync command line [DBGTGT]option to change this behavior. You can then get a meaningful [DBGTGT]backtrace from your debugger if you break on the gdk_x_error() function.) [DBGTGT] aborting... Question: how can I give --sync parameter for the program when I run it under gdb? I tried: $ gdb 'framedem --sync' which says: framedem --sync: No such file or directory. and: $ gdb framedem --sync which says: gdb: unrecognized option '--sync' Use `gdb --help' for a complete list of options. I can give the parameter in Lazarus Run Parameters... but then the whole Lazarus freezes. It doesn't take mouse clicks and must be killed.

This update is mostly commited because of PostMessage() :), but also affects unthreaded apps, because our message queue does not rely on critical sections, but parallel g_main_context, which is more effective in multi threaded environment. $ gdb framedem --sync which says: gdb: unrecognized option '--sync' Use `gdb --help' for a complete list of options.

Thanks Marc and Felipe for your help. Both run --sync and set args --sync work equally well. Zeljan, I tested also a single dash (-sync) but it doesn't work. It says: Starting program: /home/juha/SW/Pascal/thtmlport2/demo_src/framedem -sync [Thread debugging using libthread_db enabled] Detaching after fork from child process 4763. Detaching after fork from child process 4764. TApplication.HandleException Can't locate file: -sync Stack trace: $00849E34 line 2600 of framview.pas ... and the stack trace is not very helpfull. With double dash it gives the following stack trace. Note: I don't expect anyone else to solve it. It is here just for curiosity. I must say I am little obsessed with this bug now... And sorry for hijacking this thread, I will get back to the original issue later.
