EGL classes in frameworks/base have to be updated to support
64-bit platforms. Key changes in the EGL classes include
[x] EGLObjectHandle class - EGLObjectHandle class has two public
methods (constructor and getHandle) that assume handles are
32-bit. They have not been changed. Instead, two new hidden
methods (EGLObjectHandle(long) and getNativeHandle) have been
added.
[x] EG14 class - Two public methods eglGetDisplay and
eglCreatePbufferFromClientBuffer assume that handles are 32-bit.
They have been changed to throw unsupported operation exception
on non 32-bit machines. Two new methods eglGetDisplay(long)
and eglCreatePbufferFromClientBuffer(...long buffer..) have
been added to support 64-bit handles.
To allow the above changes in frameworks/base EGL classes,
corresponding code generation mechanism in frameworks/native has
been updated.

Initially populated with EGL_ANDROID_presentation_time (moved from the
EGL14 class) and the ES-relevant parts of EGL_KHR_create_context.

Some of these are new ES3 functions, some are existing ES2 functions
that can now use the new pixel pack/unpack buffer bindings.
glDrawElementsInstanced needs a special case since the pointer/offset
arg isn't the last one like the generator assumes.

Return values are declared with the C return type, but the JNI
function returns the JNI return type. In the case of GLsync/jlong as
in glFenceSync(), this causes a compile error. So the generator now
explicitly casts the return value to the JNI return type.

Added EGL extension to set a timestamp on a surface.
Also, fix JNI encoding of "long" in glgen.
Bug 8191230
Change-Id: I38b7334bade3f8ff02bffe600bb74469ef22c164
- added support for comments in checks.spec
- added most missing checks
- added and commented with // special-cased functions
- added and commented with # functions that are still missing validation checks
- moved glGet* to a special case and updated all the "pnames" from the khronos spec
- changed ifcheck to default to 1 value. this allows us to simplify the checks.spec file
and handle unknown pnames automatically (they'll be validated against 1 value, if
it happens to need more, the call will go through but the validation will not
happen).
- refactored the cpp headers in to a common header + GLES version specific
header

This fixes the glgen code generation for methods
which have a buffer arg that can be NULL.
Bug: 6845189

This changes generation of the OpenGL bindings to prevent
crashes of methods with more then one nio buffer argument.

Just use jniThrowException instead. Note that it would be trivial to throw
seemingly more appropriate exceptions (NullPointerException and
OutOfMemoryException in particular), but I'm only attempting to preserve
existing behavior here.
I also found shadowing bugs in some of the special-case functions, which
would previously always have leaked memory.
This also moves an accidental change to a generated file (ActivityThread ->
AppGlobals) into the generator, so it won't be overwritten in future.

Adds support for formerly-unimplemented methods:
glCurrentPaletteMatrixOES
glLoadPaletteFromModelViewMatrixOES
glMatrixIndexPointerOES
glWeightPointerOES
The bulk of the changes are related to implementing the two PointerOES
methods, which are implemented pretty much the same way as the existing
Pointer methods were implemented.
This change also changes the way glPointSizePointerOES is implemented,
making it act like all the other Pointer methods. (Previously it was
not handling non-direct-buffer arguments correctly.)
Fixes bug 2308625 "Support matrix palette skinning
in JSR239 and related APIs"
Also updated GLLogWraper to fix two bugs in GLLogWrapper that were
discovered while testing matrix palette skinning support:
a) Handle trying to print the contents of null-but-enabled buffers.
(It's not legal to draw with null-but-enabled buffers, and
in fact some OpenGL drivers will crash if you try to render in this
state, but there's no reason the GLLogWrapper should crash while trying
to debug this situation.
b) Don't read off the end of a vertex buffer with non-zero position when
printing the entire contents of the vertex buffer. Now we only print from
the current position to the end of the buffer.
Without the size checks it's possible for calls to glBufferData
and glBufferSubData to read off the end of the Buffer object's
data, which can cause page faults.
Fix end-of-line characters for the "spec" files. (That's why
every line of these files is changed.)
Enhance our code emitter to properly handle bounds checks for
possibly-null pointers.
JSR239 and android.opengl gl Pointer functions (glColorPointer, etc.)
now respect the current setting of the Buffer position.
This fixes a regression introduced when we started requiring the
Buffers passed to the Pointer functions to be direct Buffers.
This was always a documented restriction, but was not enforced by the runtime until now.
Until now, if you passed in some other kind of buffer, it would sometimes work, and
sometimes fail. The failures happened when the Java VM moved the buffer data while
OpenGL was still holding a pointer to it.
Now we throw an exception rather than leaving the system in a potentially bad state.
This change adds four new public classes that expose a static OpenGL ES 1.1 API:
android.opengl.GLES10
android.opengl.GLES10Ext
android.opengl.GLES11
android.opengl.GLES11Ext
Benefits:
+ The static API is slightly faster (1% to 4%) than the existing Interface based JSR239 API.
+ The static API is similar to the C API, which should make it easier to import C-based
example code.
+ The static API provides a clear path for adding new OpenGL ES 1.1 extensions
and OpenGL ES 2.0 APIs, neither of which currently have a JSR standard.
Example:
import static android.opengl.GLES10.*;
...
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
Note that it is possible to mix-and-match calls to both the static and JSR239 APIs.
This works because neither API maintains state. They both call through to the same underlying
C OpenGL ES APIs.
Implementation details:
This change enhances the "glgen" "gen" script to generate both the original JSR239 and
new static OpenGL ES APIs. The contents of the generated JSR239 classes remained the same as before,
so there is no need to check in new versions of the generated JSR239 classes.
As part of this work the gen script was updated to be somewhat more robust, and to
work with git instead of perforce. The script prints out commands to git add the generated files,
but leaves it up to the script runner to actually execute those commands.
+ gen script is really a bash script rather than a sh script,
so declare that to be true. (For example, it uses pushd,
which is a part of bash, but not a part of sh. Not sure
how this worked until now. Possibly gen was only run in
environments where /bin/sh was really bash.
+ Check the results of the java compile of the code generator,
and abort the script if the compile fails.
+ Turn on the bash shell option that guards against using
uninitialized variables in the script.
+ Remove the generated class files.
Refactor JniCodeEmitter into two classes: a general-purpose
JniCodeEmitter and a specific Jsr239CodeEmitter. The hope is
to use JniCodeEmitter as a base for emitting static OpenGL ES
bindings.
Added @Override to overridden methods.
Removed unused imports.
Converted tabs to spaces.
Removed \r characters from end-of-lines.
Add .gitignore file to ignore the .class files that are
generated when the "gen" script is run.
