From 7c5483d5b20aed9c87c5ce3f6bc840b6546edcd1 Mon Sep 17 00:00:00 2001
From: Sven Gothel
Date: Tue, 14 Jan 2014 07:37:26 +0100
Subject: Bug 942 - Share GLBufferStateTracker ; Unify GLBufferStateTracker and
GLBufferSizeTracker (simplification)
Due to future mapped buffer tracking, the GLBufferStateTracker instance shall be shared
across shared GLContextImpl instances similar to GLSizeStateTracker!
This allows us to merge GLSizeStateTracker code into GLBufferStateTracker
to simplify the implementation.
+++
Clear the GLBufferStateTracker (@destruction) only if no more
created shares are left!

+/**
+ * Tracks as closely as possible the sizes of allocated OpenGL buffer
+ * objects. When glMapBuffer or glMapBufferARB is called, in order to
+ * turn the resulting base address into a java.nio.ByteBuffer, we need
+ * to know the size in bytes of the allocated OpenGL buffer object.
+ * Previously we would compute this size by using
+ * glGetBufferParameterivARB with a pname of GL_BUFFER_SIZE, but
+ * it appears doing so each time glMapBuffer is called is too costly
+ * on at least Apple's new multithreaded OpenGL implementation.
+ *
+ * Instead we now try to track the sizes of allocated buffer objects.
+ * We watch calls to glBindBuffer to see which buffer is bound to
+ * which target and to glBufferData to see how large the buffer's
+ * allocated size is. When glMapBuffer is called, we consult our table
+ * of buffer sizes to see if we can return an answer without a glGet
+ * call.
+ *
+ * We share the GLBufferSizeTracker objects among all GLContexts for
+ * which sharing is enabled, because the namespace for buffer objects
+ * is the same for these contexts.
+ *
+ * Tracking the state of which buffer objects are bound is done in the
+ * GLBufferStateTracker and is not completely trivial. In the face of
+ * calls to glPushClientAttrib / glPopClientAttrib we currently punt
+ * and re-fetch the bound buffer object for the state in question;
+ * see, for example, glVertexPointer and the calls down to
+ * GLBufferStateTracker.getBoundBufferObject(). Note that we currently
+ * ignore new binding targets such as GL_TRANSFORM_FEEDBACK_BUFFER_NV;
+ * the fact that new binding targets may be added in the future makes
+ * it impossible to cache state for these new targets.
+ *
+ * Ignoring new binding targets, the primary situation in which we may
+ * not be able to return a cached answer is in the case of an error,
+ * where glBindBuffer may not have been called before trying to call
+ * glBufferData. Also, if external native code modifies a buffer
+ * object, we may return an incorrect answer. (FIXME: this case
+ * requires more thought, and perhaps stochastic and
+ * exponential-fallback checking. However, note that it can only occur
+ * in the face of external native code which requires that the
+ * application be signed anyway, so there is no security risk in this
+ * area.)

- * Tracks as closely as possible the sizes of allocated OpenGL buffer

- * turn the resulting base address into a java.nio.ByteBuffer, we need
- * to know the size in bytes of the allocated OpenGL buffer object.
- * Previously we would compute this size by using
- * glGetBufferParameterivARB with a pname of GL_BUFFER_SIZE, but
- * it appears doing so each time glMapBuffer is called is too costly
- * on at least Apple's new multithreaded OpenGL implementation.
- *
- * Instead we now try to track the sizes of allocated buffer objects.
- * We watch calls to glBindBuffer to see which buffer is bound to
- * which target and to glBufferData to see how large the buffer's
- * allocated size is. When glMapBuffer is called, we consult our table
- * of buffer sizes to see if we can return an answer without a glGet
- * call.
- *
- * We share the GLBufferSizeTracker objects among all GLContexts for
- * which sharing is enabled, because the namespace for buffer objects
- * is the same for these contexts.
- *
- * Tracking the state of which buffer objects are bound is done in the
- * GLBufferStateTracker and is not completely trivial. In the face of
- * calls to glPushClientAttrib / glPopClientAttrib we currently punt
- * and re-fetch the bound buffer object for the state in question;
- * see, for example, glVertexPointer and the calls down to
- * GLBufferStateTracker.getBoundBufferObject(). Note that we currently
- * ignore new binding targets such as GL_TRANSFORM_FEEDBACK_BUFFER_NV;
- * the fact that new binding targets may be added in the future makes
- * it impossible to cache state for these new targets.
- *
- * Ignoring new binding targets, the primary situation in which we may
- * not be able to return a cached answer is in the case of an error,
- * where glBindBuffer may not have been called before trying to call
- * glBufferData. Also, if external native code modifies a buffer
- * object, we may return an incorrect answer. (FIXME: this case
- * requires more thought, and perhaps stochastic and
- * exponential-fallback checking. However, note that it can only occur

Subject: Bug 942: GLBufferObjectTracker: Tracking GLBufferStorage accurately,
synchronized and secure [1/2]
GLBufferSizeTracker becomes GLBufferObjectTracker
and tracks the buffer's data store, GLBufferStorage, accurately, synchronized and secure.
Synchronization is required, since the GLBufferStorage can be
shared across many GLContext on multiple threads.
This requires all GLBufferStorage lifecycle affecting GL functions
to utilize synchronized GLBufferObjectTracker methods
while passing a native GL-func callback.
These GL functions are:
- glBufferData, glBufferStorage (GL 4.4), glNamedBufferDataEXT
Creating the GLBufferStorage object
- glMapBuffer, glMapBufferRange, and their *Named*EXT variants
- glUnmapBuffer, glUnmapNamedBufferEXT
'glDeleteBuffers' can simply notify the GLBufferObjectTracker
No more HashMap is required to associate the mapped buffer address
to the mapped ByteBuffer.
GLBufferObjectTracker simply utilizes a
buffer-name (int) -> GLBufferStorage
map.
+++
The security aspect shall be implemented by validating all arguments
whether they match the required GL constraints,
as well as validating tracked states like 'size'.
The following functions will throw an GLException accordingly:
- glBufferData, glNamedBufferDataEXT
* @throws GLException if size is less-than zero
* @throws GLException if a native GL-Error occurs
- glBufferStorage (GL 4.4)
* @throws GLException if size is less-or-eqaul zero
* @throws GLException if a native GL-Error occurs
- glMapBuffer, and it's *Named*EXT variant
* @throws GLException if buffer is not bound to target
* @throws GLException if buffer is not tracked
* @throws GLException if buffer is already mapped
* @throws GLException if buffer has invalid store size, i.e. less-than zero
- glMapBufferRange, and it's *Named*EXT variant
* @throws GLException if buffer is not bound to target
* @throws GLException if buffer is not tracked
* @throws GLException if buffer is already mapped
* @throws GLException if buffer has invalid store size, i.e. less-than zero
* @throws GLException if buffer mapping range does not fit, incl. offset
- glMapBufferRange, and it's *Named*EXT variant
Only clear mapped buffer reference of GLBufferStorage
if native unmap was successful.
Further more special error handling shall be applied to:
- glMapBuffer, and it's *Named*EXT variant,
glMapBuffer, and it's *Named*EXT variant
- A zero GLBufferStorage size will avoid a native call and
returns null
- A null native mapping result indicating an error will
not cause a GLException but returns null
This allows the user to handle this case.

- storage creation with target via {@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}
+ * - {@link GL#glBufferData(int, long, java.nio.Buffer, int)} - storage recreation with target via {@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}
+ * - {@link GL2#glNamedBufferDataEXT(int, long, java.nio.Buffer, int)} - storage recreation, direct, via {@link #createBufferStorage(GL, int, long, Buffer, int, CreateStorageDispatch, long)}
+ *
+ * Note that storage recreation as mentioned above also invalidate a previous storage instance,
+ * i.e. disposed the buffer's current storage if exist and attaches a new storage instance.
+ *
+ *
+ * Buffers storage is disposed via
+ *
+ * - {@link GL#glDeleteBuffers(int, IntBuffer)} - explicit, direct, via {@link #notifyBuffersDeleted(int, IntBuffer)} or {@link #notifyBuffersDeleted(int, int[], int)}
+ * - {@link GL#glBufferData(int, long, java.nio.Buffer, int)} - storage recreation via target
+ * - {@link GL2#glNamedBufferDataEXT(int, long, java.nio.Buffer, int)} - storage recreation, direct
+ *
+ *
+ *
+ *
+ * Implementation throws a {@link GLException} in all construction methods as listed below,
+ * if GL-function constraints are not met. createBufferStorage
also throws an exception
+ * if the native GL-function fails.
+ *
+ * - {@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}, etc ..
+ * - {@link #mapBuffer(GLBufferStateTracker, GL, int, int, MapBufferAllDispatch, long)}, etc ..
+ *
+ * In destruction and informal methods, i.e. all others, implementation only issues a WARNING debug message, if enabled.
+ *
+ *
+ *
+ * Buffer mapping methods like {@link GL#mapBuffer(int, int)} ...,
+ * require knowledge of the buffer's storage size as determined via it's creation with
+ * {@link GL#glBufferData(int, long, java.nio.Buffer, int)} ....
+ *
+ *
+ * Hence we track the OpenGL buffer's {@link GLBufferStorage} to be able to
+ * access the buffer's storage size. The tracked {@link GLBufferStorage} instances
+ * also allow users to conveniently access details of their created and maybe mapped buffer storage.
+ *
+ *
+ * The {@link GLBufferObjectTracker} and it's tracked {@link GLBufferStorage} instances
+ * maybe shared across multiple OpenGL context, hence this class is thread safe and employs synchronization.
+ *
+ *
+ * Implementation requires and utilizes a local {@link GLBufferStateTracker}
+ * to resolve the actual buffer-name bound to the given target.
+ *
+ *
+ * Note: This tracker requires to be notified about all OpenGL buffer storage operations,
+ * as well as the local {@link GLBufferStateTracker} to be notified about all
+ * OpenGL buffer binding operations.
+ * Hence buffer storage cannot be accessed properly if managed via native code.

-/**
- * Tracks as closely as possible the sizes of allocated OpenGL buffer
- * objects.
- *
- * glMapBuffer
or glMapBufferRange
etc
- * returns a java.nio.ByteBuffer
- * instance reflecting the returned native address of respective calls
- * and the actual buffer size.
- *
- *
- * In case the buffer size is unknown, we need to compute this size by using
- * glGetBufferParameteriv
with a pname of GL_BUFFER_SIZE
.
- * The latter appears to be problematic due to the returned int
value,
- * where size should be of type long
.
- * Further more, this query appears to be costly for each glMapBuffer call
- * at for Apple's new multithreaded OpenGL implementation.
- *
- *
- * The buffer size state is shared across all shared OpenGL context,
- * hence we share the GLBufferSizeTracker instance across all shared GLContexts.
- * Hence utilizing this instance must be synchronized to be thread safe due to multithreading usage.
- *
- *
- * We track the sizes of allocated buffer objects.
- * We track calls to glBindBuffer
etc to see which buffer is bound to
- * which target and to glBufferData
to see how large the buffer's
- * allocated size is. When glMapBuffer
is called, we consult our table
- * of buffer sizes to see if we can return an answer without a glGet
- * call.
- *
- *
- * In the face of calls to glPushClientAttrib / glPopClientAttrib we currently punt
- * and re-fetch the bound buffer object for the state in question;
- * see, for example, glVertexPointer
and the calls down to
- * GLBufferStateTracker.getBoundBufferObject()
. Note that we currently
- * ignore new binding targets such as GL_TRANSFORM_FEEDBACK_BUFFER_NV
;
- * the fact that new binding targets may be added in the future makes
- * it impossible to cache state for these new targets.
- *
- *
- * Ignoring new binding targets, the primary situation in which we may
- * not be able to return a cached answer is in the case of an error,
- * where glBindBuffer
may not have been called before trying to call
- * glBufferData
. Also, if external native code modifies a buffer
- * object, we may return an incorrect answer. (FIXME: this case
- * requires more thought, and perhaps stochastic and
- * exponential-fallback checking. However, note that it can only occur
- * in the face of external native code which requires that the
- * application be signed anyway, so there is no security risk in this
- * area.)
