commit 0516cdc0f9dc0969ac96df6984af2413680cad01 Author: Cedric BAIL <[email protected]> Date: Wed Jun 14 12:42:25 2017 -0700 evas: use Eina_List instead of Eina_CList for event grabber. Eina_Clist can actually change the pointer in the cell next bypassing the CoW infrastructure leading to trouble. Considering the case here, using the optimization of Eina_Clist is not necessary and if performance issue arise, can be fixed by using a dichotomic search when removing data. I don't think it is necessary to add this complexity without a real life case. --- .../evas/canvas/efl_canvas_object_event_grabber.c | 150 +++++++++------------ src/lib/evas/canvas/evas_callbacks.c | 4 +- src/lib/evas/canvas/evas_events.c | 56 +++----- src/lib/evas/include/evas_private.h | 13 +- 4 files changed, 90 insertions(+), 133 deletions(-) diff --git a/src/lib/evas/canvas/efl_canvas_object_event_grabber.c b/src/lib/evas/canvas/efl_canvas_object_event_grabber.c index 30d3f88521..0292de0f9d 100644 --- a/src/lib/evas/canvas/efl_canvas_object_event_grabber.c +++ b/src/lib/evas/canvas/efl_canvas_object_event_grabber.c @@ -10,7 +10,8 @@ struct _Efl_Object_Event_Grabber_Data { Eo *rect;
