2004-11-12 Matthias Clasen <mclasen@redhat.com> Changes to make gdk-pixbuf threadsafe (#157310, #157306, Colin Walters): * gdk-pixbuf-io.h (enum GdkPixbufFormatFlags): Add GDK_PIXBUF_FORMAT_THREADSAFE to indicate that an image loader is threadsafe. * gdk-pixbuf-io.c (get_file_formats, _gdk_pixbuf_load_module): Use a lock to make initialization of global data structures threadsafe. * gdk-pixbuf-private.h: * gdk-pixbuf-io.c (_gdk_pixbuf_lock, _gdk_pixbuf_unlock): Auxiliary functions which use another lock to protect threadunsafe image loaders. * gdk-pixbuf-io.c (gdk_pixbuf_real_save): (save_to_callback_with_tmp_file): (gdk_pixbuf_real_save_to_callback): (gdk_pixbuf_new_from_xpm_data): (_gdk_pixbuf_generic_image_load): * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): (gdk_pixbuf_loader_close): (gdk_pixbuf_loader_finalize): Use _gdk_pixbuf_lock() and _gdk_pixbuf_unlock(). * io-ani.c, io-bmp.c, io-gif.c, io-ico.c: * io-jpeg.c, io-pcx.c, io-png.c, io-pnm.c: * io-ras.c, io-tga.c, io-wbmp.c, io-xbm.c: * io-xpm.c: Mark as threadsafe. * io-tiff.c: Remove pointless locking, mark as threadunsafe.
