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.

this modifies the zero copy texture feature to map and unmap on get and put

Dear all,
I attached a patch of evas_gl_shader.
I've removed a comment which is creating dummy shader when using GL_OES_get_program_binary extension.
Mr. Haegeun Park who is in charge of GPU driver fixed get_program_binary bug in the SGX driver.
There's no need to create dummy shaders any longer.
And I've added link status checking code to validate the binary object.
Please review this patch.
Thanks.

Subject: [E-devel] [Patch] Evas gl shader use binary shader
I make patch related with evas gl binary shader.
The concept of binary shader is compile shader only once.
Some people want to use binary shader because of performance issue.
In current evas gl engine, every application have to compile shader each
time.
But I modify code , so only first running application need compile shader.
Other application use already compiled shader(binary shader)
The binary shader is made under HOME/.evas/gl_common_shaders directory.
Binary shader is created according to GL vendor,GL renderer, GL version and
Module_arch.
The basic flow is
1. First running application which use gl engine check binary shader
directory, but it can't find binary shader.
2. After compiling shader, It saves compiled shaders..
3. Other application checks shader directory, it can use binary
shaders.
In mobile target, using binary shader, I can save 150ms. (that time, there
is 11 shaders).
If there is more shaders and more applications, this flow maybe save more
total time.
(the above is now in, changelog coming, with change to using ~/.cache,
some formatting fixes, make ity do the desktop gl one right with the
retrievable hint parameter ont he program etc. - doesn't break desktop
gl at least. yay. a,so fixes to mke it compile at all).

Subject: evas_gl_api_get patch.
Here's a patch that simply overrides the GL functions for Evas_GL
except for two functions that I provide on my own. It may have some symbol
resolving warnings but that'll all go away eventually when we do everything
via dlsym or getProcAddress.
You can apply the patch to the latest revision of evas. (I've just
updated them) I'm also attaching a sample GLES program that uses
evas_gl_api_get. You don't need to link it to -lGL.

More work, proudly supported by Samsung. Filters!
So now you can apply a whole host of cheesy visual effects to objects at
runtime. This is the first commit, there are a couple of more to come as I
tweak the filters, and fix blur with GL[1].
Please direct bugs to me nash@nash.id.au.
[1] You'd think shaders would be good at this.. but no, generic blur and GL
are like trying to get an apple product to work with Linux.

This seems to have got lost in my big messup before. This pushes enough of
mask/arbitrary clip to be somewhat useful. I need to push a little more soon
for it to be 100% happy, but this is useful level.

Proxy objects allow you to use another image as the source of an image.
Essentially allowing the same object to be rendered multiple times. One
object (the source) is the original, each additional 'copy' is an image with
evas_object_image_source_set.
This is complete.
Also add partially working arbitrary maps, and arbitrary clipping.
Unfortunately both have some issues yet to be resolved (waiting on the next
feature to get merged together).

engine on shutdown. was freeing the wring kind of thing in the first
place.. and even then it should be more robust, so fix gl texture
robustness and this bug. can cause on-exit crashes if not fixed.

* log domains in lower-case only please. let's make it a standard so
we don't have to look at the code everytime to figure out the name...
* logs do NOT require trailing newline (\n), it's automatic!
* do NOT add newline inside log messages!
* add gl_common logging.
NOTE: I tried to compile all modules, but there are clear broken
modules such as cairo and qtopia. Other modules like gl_sdl are
broken as they were not updated to new gl_common api (resize
method AFAIR).
