currently evas_object_event_callback_call checks _evas_event_counter
for preventing object's callback called several times in one evas event.
but it use global variable(_evas_event_counter), it can be changed while
procssing same event.
for example , evas_event_feed_mouse_up.
If there are several object in e->pointer.object.in and object 1's callback
create new evas event, object 2 cannot now event id.
so I change callback call api, and object callbacks can decide wheather it deal with that event.

addition to evas gl backend.
Working on different mobile devices, we've noticed that the cost of context
switch (MakeCurrent) in GL can be very expensive depending on the driver
implementation. To minimize the poorly written driver's context switch
overhead, I've implemented a state tracking layer on top of the driver
implemented GL.
Essentially, this layer wraps all the GL/Glue(GLX/EGL) APIs and manages its own
state changes. Internally, only one real GL context is created and logical
contexts are created every time a user requests context creation. The logical
contexts keep track of its states and sets only the necessary states
(the ones that are different than the current ones)
when there is a MakeCurrent request. The real MakeCurrent gets called when
there is a Surface/Window change request.
The GL library is dlopened and all the APIs are dlsym'ed and wrapped
accordingly. All the GL functions are in evas_gl_core.{h,c}.
Here's a very simply flow of the code.
- all the APIs are exported as function pointers (*glsym_glBegin),
(*glsm_eglCreatContext), and etc.
- all the native GL/Glue(GLX/EGL) APIs are dlsym'ed as _sym_glBegin,
_sym_eglCreateContext, and etc.
- all the fastpath APIs are implmemnted as fpgl_glBegin,
fpgl_eglCreateContext, and etc.
- if faspath is seletected, the exported APIs are set accordingly
ie. glsym_glBegin = fpgl_glBegin;
- default mode is the regular gl symbols are directly set.
ie. glsym_glBegin = _sym_glBegin;
I have an Environment variable where you can set it to three different Modes
EVAS_GL_FASTPATH = 0 // Default mode. Regular GL symbols are directly loaded
EVAS_GL_FASTPATH = 1 // Fastpath mode. Takes the path described above.
EVAS_GL_FASTPATH = 2 // Wrapped mode. All the regular GL functions are
wrapped once. This can be used for various
purposes
Since all the GL symbols are now loaded in this library, I took out all
the gl symbol loading parts in the evas gl backend as you'll see in the patch.
The changes to the engine and the backend itself is pretty minor.
There are still some known issues to hammer out but I thought we're at a good
place for an initial version so that my source doesn't diverge too much.
Known Issues and To Do's
* Current GL Fastpath version doesn't support multiple threads. Instead of
having one global real context, I would need to do it for each thread. I'll
get on this soon.
* Issues running Evas GL on certain conditions. When running the elementary
test (with gl engine), if you run ELMGLview test that runs in ON_DEMAND mode,
everything works fine. BUT, when you run the ELMGLView test in ALWAYS
mode, the subsequent elm tests shows blank screen. When you destroy the
GLView window, everything else comes on fine.
* Resource protection code. This actually applies to Evas GL code in general
as well. Since all the resources are shared among all the contexts that get
created, I would like to eventually have a resource protecting mechanism that
prevents access to resources outside of its context unless specifically
specified.
I'm attaching three files
- evas_gl_core.h, evas_gl_core.c, fastpath.patch
To get the code running...
- copy evas_gl_core.{c,h} to src/modules/engine/gl_common/
- apply the fastpath.patch
- compile/install evas
- to run with fastpath GL (ie. % EVAS_GL_FASTPATH=1 ./evasgl_sample1)

Subject: [E-devel] [Patch] [Evas] Patch to provide information of
touched points
Hello,
I made a new patch to get information of current touched point instead
of Touch Event.
I added touch_points (Eina_List) to the Evas structure and it maintains touched points on the evas.
New touched point is added to the touch_points when we get Mouse_Down and Multi_Down,
touched point is updated when we get Mouse_Move and Mult_Move,
and touched point is removed when we get Mouse_Up and Multi_Up.
The each touch point has coordinate, id and state information as follows:
id - identifier. 0 for Mouse Event and device id for Multi Event. coordinate - (x, y) coordinate of point.
state - state of point. type is Evas_Touch_Point_State enum.
(EVAS_TOUCH_POINT_DOWN, EVAS_TOUCH_POINT_UP, EVAS_TOUCH_POINT_MOVE,
EVAS_TOUCH_POINT_STILL, EVAS_TOUCH_POINT_CANCEL)
There are 4 new APIs to get touch point's information as follows:
unsigned int evas_touch_point_list_count(Evas *e);
void evas_touch_point_list_nth_xy_get(Evas *e, unsigned int n, Evas_Coord *x, Evas_Coord *y);
int evas_touch_point_list_nth_id_get(Evas *e, unsigned int n);
Evas_Touch_Point_State evas_touch_point_list_nth_state_get(Evas *e, unsigned int n);
I added APIs to get each information instead of exposing whole
structure to make it easy to expand in the future as you mentioned in
the below e-mail :)

Subject: Re: [E-devel] [E-Devel][Review][Patch] Evas GL Extensions + a
bug fix
Here's an initial attempt at the GL extensions issue for Evas GL.
I have been in discussion with a few EFL developers regarding how we should
provide extensions. Essentially, there are two ways to go about doing this.
1. provide evas_gl_proc_address_get() function as it is done in other
glue layers
2. provide all the extension functions in the EVAS_GL_API struct.
#1 approach is how it's done in other glue layers and the driver implementor can
provide new extensions easily. It is however pretty annoying to get the
function prototypes right and use the function pointers and etc.
#2 approach provides all the extension functions in the struct so it's
definitely easier to use. Adding new extensions can be a pain as people may
have to wait for new version releases.
For now, we thought it was OK to just throw them in the struct as in
#2 and try it out. So, I've implemented this approach. As for the extensions,
I've basically included all the extensions in gl2ext.h as EvasGL currently
provides all the GLES 2.0 functions. In order to display the right
information, I had to override glGetString() with GL_EXTENSIONS as parameter to properly
display the supported extensions.
Also, I've added a few EGL extensions that have been
modified for EvasGL use. For example, eglCreateImage/eglDestroyImage has been
defined as folllows.
EvasGLImage (*evasglCreateImage) (int target, void* buffer, int*
attrib_list); void
(*evasglDestroyImage)
(EvasGLImage image);
const char *evas_gl_string_query() function was added to return a string of
supported EvasGL extensions. So essentially, a user can search this string to see
if the desired extension is supported. if it is, he can use the functions. He can
always check if the function pointers are NULL as well.
Take a look at the pach and let me know what you think.
______________
While I was adding the extension code, I've added a few fixes/ changes
to the EvasGL.
1. glDeletBuffers bug
- When I wad destroying evasgl context, I was deleting the context FBO with
glDeleteBuffers instead of glDeleteFramebuffers. This code in effect was
deleting BOs in other contexts and we had some funky behaviors as a
result. The
bug has been fixed.
2. make_current
- I've made some changes to the make current code and also added a resource
context to the engine data. the resource context is used for creating surface
texture/ fbos when surface/ context is created. Before, i was using evas'
context but thought it'd be a good idea to use a separate context.

You can't compile a gl_common .c file based on whether or not the SDL
header was included. The .c file will result in only one .o and since
the Evas_Engine_Sdl.h is not included by evas_gl_context.c itself, then
that ifdef will never be true.
gl_common should request a callback function pointer from the evas engine
for doing symbol resolution. This needs a refactor.

Subject: [E-devel] [Patch] Evas touch event patch.
Nice to meet you.
I'm Eunmi Lee, developing mobile web browser and working on WebKit EFL port.
I need new type of event for touch, so I've made patch to add
EVAS_CALLBACK_TOUCH event to the evas.
I will explain history of this patch.
Currently, many web applications and sites use TouchEvent and they can
do everything(scrolling, zooming and so on) like native application
using TouchEvent.
So, I'm also want to provide TouchEvent for web in the WebKit EFL port,
but I got a problem during making TouchEvent because EFL's touch
event's structure (Mouse, Multi Event) is different from Web
TouchEvent's one.
Let me explain about Web TouchEvent firstly.
Web TouchEvent is consist of type and touch points list simply.
There are 3 kinds of type.
TouchStart: Happens every time a finger is placed on the screen.
TouchEnd: Happens every time a finger is removed from the screen.
TouchMove: Happens as a finger already placed on the screen is moved
across the screen.
for example, we can make (1 finger starts to touch), (2 fingers are
moving), (1 finger is released duirng 3 fingers are moving) and so on.
You can see the detailed information in the following url:
http://www.sitepen.com/blog/2008/07/10/touching-and-gesturing-on-the-iphone
However, EFL's touch event is consist of six kinds of type :
MOUSE_DOWN, MOUSE_UP, MOUSE_MOVE, MULTI_DOWN, MULTI_UP, MULTI_MOVE.
So, I have to make a converter to make web touch event from EFL's
touch event.
You can reference attatched image file : evas_touch_event.png.
To tell the truth, converting code is not a big one.
But, I want to reduce this additional job and make code simple.
In the WebKit QT port, they don't have to make converting code for
TouchEvent,
because they have QTouchEvent, it has type and touchPoints list and
they can be mapped to Web TouchEvent one by one.
I think iPhone and Android also have such kind of event.
That's all why I want to add new touch event type to the evas.
about my patch:
- EVAS_CALLBACK_TOUCH event is added
- touch_points Eina_List is added to the Evas structure to maintain
current touch lists.
- process MOUSE/MULTI UP, DOWN, MOVE to make TOUCH event.
It is my first time to modify eves codes and actually I don't know too
much about evas.
So, I will be grateful if you send any feedback and comments.

Now, smart callback is prepended among the same priorities. After the

I fixed this because I think it's better keeping the default behavior
even we have new priority option. This is for evas backward
compatibility and for the world peace. Although I know there is no
official policy and it's not recommended to rely on the smart callback
calling sequence in application, I really hope evas needs to have
compatibility. Otherwise we need to adopt the new policy in next
version of evas.

Subject: [E-devel] [Review] [Patch] Evas_GL bug fixes/updates
I've fixed some minor issues that I've been pushing off for later.
The patch does the following:
1. Evas_GL and Evas had an issue where the viewport parameters were
being reset in the wrong context. Previously, this issue was temporarily
patched by flushing evas' pipeline and setting
evas_gl_common_context_use(NULL) in EvasGL's
make current. I know, it was pretty hacky. It turns out that in
evas_engine,
there was a code evas_gl_common_context_resize(NULL) without doing
eng_window_use() first. So i've added that part and problem went was
resolved properly. :-)
2. Naturally, I've taken out the temporary patch from 1.
3. I've added code that took care of glBindFramebuffer(..., fbo) where
the
fbo had to be saved and restored in case the user wanted to use his
own fbo.
Also, I've had to take care of the case when fbo is 0 since 0 need to
point
to evas_gl surface.
4. I've updated make_current a little as well.

Subject: [E-devel] [Patch] evas gl engine's texture creation
Hello.
1. _pool_tex_dynamic_new function, it didnt set pt to NULL when secsym_eglCreateImage function failed.
In this case, it returns wrong pt pointer and it has possibility to make crash.
So I add free pt code and return NULL code into _pool_tex_dynamic_new function.
2. I modified eng_image_data_get of gl engine.
If Evas_GL_Image's texture creation failed and evas_gl_image's cache image was droped,
Im->im can be NULL. So I add check code.
Example: evas_gl_common_image_content_hint_set
1) EVAS_IMAGE_CONTENT_HINT_DYNAMIC , it drop cache image
2) if evas_gl_common_texture_dynamic_new failed
3) then, im->im =NULL, im->tex=NULL
In this situation, if application call's evas_object_image_data_get function,
It make crash in evas_cache_image_load_data function.
3. I think function's related with evas_object's engine data have to be return NULL if it failed.
If function's returns null, evas object code can handle error more easily.
But evas object's code was implemented differently each case. Does my suggestion right?
I add engine data null check code to evas_object_image based on upper consumtion.
If it is wrong , the patch code related with evas object image have to be removed.
If it is right , I will survey other evas object type also.
