Subject: [E-devel] [patch] evas - preventing retard mouse event
process in evas_object_event_callback_call
I made a small patch to prevent retard mouse event process.
At certain circumstance (like as genlist select callback + naviframe
item push),
some events are repeat processed.
If some evas_objects're iterating in evas_event_feed_mouse_up and
mouse_out event's emitted by other interrupt(such as naviframe item
push),
then some evas_objects events are multiple processed by
evas_object_event_callback_call.
More elaborating it with a example.
There are a genlist and a multibuttonentry on genlist item.
When a user clicks multibuttonentry then evas will process mouse down
and up.
in evas_event_feed_mouse_up, it gets evas object list to process mouse
events.
Then in the evas object list, there are two evas objects - rect and
textblock.
Two objects have its own parents.
the rect has below parents.
----------------------------------------
edje - genlist item
elm_genlist_pan
edje
multibuttonentry
box
entry
els_scroller (0x2a601788)
rect <== the rect
the textblock has below parents.
----------------------------------------------
edje - genlist item
elm_genlist_pan
edje
multibuttonentry
box
entry
els_scroller(0x2a601788)
edje
elm_pan
edje
textblock <== the textblock
(note : two evas object have same parent (els_scroller))
So normally mouse up callbacks event propagates to its own parent.
the rect is processed to genlist item. and the textblock is processed
to genlist item.
but when els_scroller is processed, it's blocked by checking event
type and event id checking.
Mouse Up(rect) -> Mouse Up(textblock)
event_id (3) -> event_id (3)
evas_object_event_callback_call(Evas_Object *obj, Evas_Callback_Type
type, void *event_info, int event_id)
{
...
if ((obj->delete_me) || (!obj->layer)) return;
if ((obj->last_event == event_id) &&
(obj->last_event_type == type)) return;
<=== blocked
However if naviframe item is pushed in the middle
of mouse up processing.
It can break into mouse up. So it's processed like below.
Mouse Up(rect) -> Mouse Out(rect) -> Mouse Out(textblock) -> Mouse
Up(textblock)
event_id (3) -> event_id(4) -> event_id(4)
-> event_id(3)
(note Mouse_Out is made by naviframe item push for event freezing)
If that, there's no mechanism to block that repeat processing same
event.
So I suggest this patch.
This patch blocks old events if there's no reason to process.
(It blocks old mouse_up event because mouse_out is processed.)
And I think it also clear the bug in

if file was chaned by somebody, it was added to dirty list during cache request.
currently this dirty image added to cache->dirty list and never freed until image shutdown.
but dirty image of chaned file never used so add delete code for memory efficiency.

option.
It should have been OR instead of AND operator.
When the image object alpha is on "OR" the rotation angle
is not "0", direct rendering isn't allowed. However,
allow direct rendering if EVAS_GL_DIRECT_OVERRIDE=1 is set.

This optimization is significant for rendering to a large surface
because it'l save an extra copy overhead as well as an extra rendering pass.
To enable it, you can give EVAS_GL_OPTIONS_DIRECT hint in the surface
config options_bits. The following conditions have to be met in order
for evas to render directly into the Evas' window. If they are not met, the
engine will fallback to rendering to an FBO as it normally does.
conditions:
1.) All the GL calls have to be called using the pixel_get_callback function.
This is necessary for the evas object order to be maintained.
2.) Alpha must be disabled on the image ojbect that renders evas_gl.
3.) No rotation allowed.
One way to override above condition is to set EVAS_GL_DIRECT_OVERRIDE=1 but
there is no guarantee in its behavior.
Currently, this optimization is added for gl_x11 engine only.

Make the functions static as well to avoid gcc warnings like this:
warning: 'ALPHA_SSE3' is static but used in inline function 'sub4_alpha_sse3' which is not static

This really just filters them out. The solution is not complete, nor is
it the best one. But this fixes the bugs for the meanwhile.
