Description shrdlu 2008-02-03 06:20:20 UTC

http://sudoku.repubblica.it/sudoku.php?id=20080203_03

Clicking on a blank square opens a sort of "dial" where one can select the digit to insert in the square. On my system, *only while the dial is open*, the cpu usage of forefox jumps to 100%. As soon as a digit is selected, the dial closes and cpu usage drops to normal.

I'm using swfdec and swfdec-mozilla 0.5.5, firefox 2.0.11. 64-bit Gentoo.

Confirmed, also in swfplay, so it's not a plugin bug.  Log messages when running (after "sort -u"):

SWFDEC: WARN : swfdec_as_interpret.c(908): swfdec_action_call_method: no function named "apply" on object unknown
SWFDEC: WARN : swfdec_as_interpret.c(908): swfdec_action_call_method: no function named "swapDepths" on object unknown
SWFDEC: WARN : swfdec_load_object.c(161): swfdec_load_object_load: SECURITY: no access to http://sudoku.repubblica.it/getpuzzle.php?id=undefined from file:///
SWFDEC: FIXME: swfdec_text_field_movie.c(1201): swfdec_text_field_movie_iterate: I'm pretty sure this is swfdec_player_add_action()'d
SWFDEC: FIXME: swfdec_as_function.c(165): swfdec_as_function_call: does the super object really reference the function when thisp is NULL?

The message repeating during 100% CPU utilization is:

SWFDEC: FIXME: swfdec_text_field_movie.c(1201): swfdec_text_field_movie_iterate: I'm pretty sure this is swfdec_player_add_action()'d

This is solved in git.
