Wed Apr 18 14:23:14 2001 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkimage-x11.c (gdk_image_new): Try changing mode on shm segments to 0600. We'll see who complains. * gdk/gdkwindow.c (_gdk_window_destroy_hierarchy): Call _gdk_windowing_window_destroy() AFTER recursing through children. * tests/Makefile.am (noinst_PROGRAMS): Build testsocket, testsocket_child on X. * tests/testsocket[_child].c: Fix uses of gtk_window_get_default_accel_group(). [ Merge patch from Ramiro Estrugo <ramiro@eazel.com> from gtk-1-2 ] * gdk/gdkimage.c: (gdk_image_get): Deal with the possibility that XGetImage() might return NULL. Allocate the GdkImagePrivate structure only after XGetImage() succeeds in order not to dereference a NULL ximage pointer. This prevents a core dump when XGetImage() fails - which is unlikely, but can happen due to race conditions accessing the geometries of drawables. An x error will still be triggered, but the gdk image wrapper at least wont seg fault.
