glMap*Buffer*; GLX/WGL/CgGL: All runtime dynamic; Misc ..
TODO: Compile and test on MacOSX ..
Fix:
=====
Multithreading/Locking:
See jogl/doc/Implementation/MultiThreading.txt
- Locking layer is not platform agnostic, ie GLContextImpl, GLDrawableImpl, ..
and NEWT: Window/Display
- No more use of JAWT global lock necessary, removed.
- No need for X11 Display lock, on the contrary,
this made the NV driver hang.
- Use common window/surface lock
- All NativeWindow surfaceLock's are recursive now
glMapBuffer: If size is 0, don't do cont with the native call.
glMapBufferRange: Fix capacity.
glNamedBufferDataEXT: Track the size.
glMapNamedBufferEXT: Manual impl. - use the tracked size
glXGetVisualFromFBConfig, glXChooseFBConfig, glXChooseVisual: Instead of
ignoring and implement a renamed version (*Copied), we just use ManualImplementation
for the proper copy-result code.
DesktopGLDynamicLookupHelper: Initialize _hasGLBinding* attributes
in the determing loadGLJNILibrary() method, which is called by super().
Otherwise static init will overwrite them after the super() call.
X11GLXDrawableFactory: Don't release anything at shutdown (removed sharedContext.destroy()),
since this caused a freeze/SEGV sometimes.
Fixed NEWT's reparentWindow() functionality incl NewtCanvasAWT usage.
- Native: if not visible, don't focus, etc
- NewtCanvasAWT: Use the container size to start with
- Run the command on the EDT
Using GlueGen's new DynamicLibraryBundle utility:
- X11, Windows and MacOSX OpenGL adapted to DynamicLibraryBundleInfo.
- X11GLXDynamicLookupHelper -> X11GLXDynamicLibraryBundleInfo
- Remove all path from lib names.
- GL order: libGL.so.1, libGL.so, GL
- shallLinkGlobal: true -> to server some 'old' DRI systems
-> http://dri.sourceforge.net/doc/DRIuserguide.html
- shallLookupGlobal: false
- Try both : glXGetProcAddressARB and glXGetProcAddress
- Using bootstrap: GLX.glXGetProcAddress(long glxGetProcAddressHandle, String glFuncName)
Found the issue with LIBGL_DRIVERS_PATH, ie if not set
no valid GL instance can be found (ie ATI fglrx/DRI).
This may happen if using a differen user than the desktop user
for whom the env var is set within some /etc/X11/Xsession.d/ script.
Enhancements:
=============
GLBufferSizeTracker: Use IntIntHashMap and add DirectState size tracking.
GLBufferStateTracker: Use IntIntHashMap.
GLStateTracker: Use IntIntHashMap.
GLDynamicLookupHelper: More generic (global loading/lookup and GetProcAddress function name list),
remove redundant code.
FIXME:
MacOSXCGLDynamicLookupHelper:
- Not tested
- Not using NSImage lookup anymore as recommended by OSX API Doc,
so dlsym is used always (to be tested)
WindowsWGLDynamicLookupHelper:
- Not tested
GLX/WGL/CgGL is all runtime-dynamic as now, ie loaded and looked-up at runtime,
no compile time dependencies to GL anymore, nor a need to specify CgGL.
Split up WGL in GDI and WGL, to allow proper dynamic runtime linkage of OpenGL32
while using static binding to GDI32
NEWT events generated by native code are enqueued and not send directly.
This should ease locking mechanisms .. if any are necessary.
NEWT: More platform specific code moved to *Impl method,
simplifying the generic code of the superclass and impl protocol.
Cleanup:
=========
Replace all InternalBufferUtil's with com.jogamp.common.nio.Buffers
Removed all InternalBufferUtil's from repository
Removed GLContextImpl notion of 'optimized' surface locking,
where the surface gets unlocked during makeCurrent/release.
This just makes no sense and would impact multithreading in a horrible way.

Misc.
Due to incapabilities of the previous AWT/NEWT reparenting
the implementation and spec had to be changed to support this feature.
See the first 2 comments below.
- Tested on GNU/Linux (OK), Windows (a few bugs left)
-
TODO:
- Clarify the size/layout issue, ie who is responsible etc
In the test, incl AWT/NEWT, we set the size on the GLWindow
and ie pack the AWT Frame.
- Fix remaining [Windows] bugs ..
- Fix/Implement MacOSX port ..
Fix AWT/NEWT reparenting:
===========================
- Now NewtFactory's createWindow() method for parenting handles NativeWindow only
and is no more responsible for creating a child window upon an AWT Component.
See class com.jogamp.newt.awt.NewtCanvasAWT for NEWT/AWT parenting.
- New com.jogamp.newt.awt.NewtCanvasAWT, responsible for handling
AWT's reparent events via addNotify/removeNotify.
Reparenting is implemented via the new NEWT Window's reparentWindow() method.
Also sets the background erase to false, if supported.
- Fix zero size semantics in Window (setSize/setVisible)
Since a zero size window is not supported by many compoenent (Windowing system, OpenGL, ..)
we use the visibility methodology to not show a 0x0 window. See Javadoc.
AWT components may start with zero size.
- New NEWT Window: reparentWindow(NativeWindow newParent, Screen newScreen)
Allowing to change the parent of a window. Similar with the fullscreen toggle,
but without size/position change.
Native reparenting allows to keep alive the native
window while changing the container, hence it is preferred to a destroy/create cycle.
To benefit from the native reparenting, a NEWT implementation has to implement
'protected boolean reparentWindowImpl(long newWindowHandle)'
and return true, otherwise reparenting will be 'emulated' via
the expensive destroy/create cycle.
- NEWT's Window references all of it's children, if any
- NEWT's Window propagates setVisible/destroy actions to it's children.
- Fix NEWT's destroy() semantics.
A call of destroy() or destroy(false) shall only result in the destruction of the
native window (handle) nothing more. A subsequent setVisible(true) shall allow
the complete recreation of the Window into a usable state.
A call of destroy(true) destroys all resources the Window holds,
may include Screen/Display and OpenGL resources in case of GLWindow.
This is necessary to allow proper reparenting, where a native window may become
destroyed, but should be recreated via setVisible(true) later on.
- Fix NEWT set[Size|Position|Fullscreen|Visible] synchronization.
Use a recursive lock instead of the Window instance, otherwise arbitrary Window access
via AWT's EDT, NEWT's EDT or other threads can block.
Also removed a use pattern like:
key.lock()
try {
EDT.invoke(action());
} finally {
key.unlock();
}
Where action() itself uses the same lock object (here key), the result is a deadlock.
NativeWindow Changes:
======================
- We can use XInitThreads() now (concurrent threading support)
in combination with AWT.
Might have been some async in our NEWT locking in regards to AWT (sync()),
and the X11 Display changes made in c787f50d77e2491eb0d8201d534a6fa4885a929e.
- NativeWindow's window handle is _not_ transient like surface handle,
fixed documentation.
JOGL Changes:
=============
- New 'isRealized()' method in GLDrawable.
-
Misc Fixes
============
- Fix NEWT set[Size|Position|Fullscreen|Visible] duplicate code
Due to pure abstract signatures, the set[Size|Position|Fullscreen|Visible]
implementations of X11, OSX, .. contained duplicate code and state handling (size, pos, ..).
These are now decoupled, ie generic set[Size|Position|Fullscreen|Visible] implementations
calling simple set[Size|Position|Fullscreen|Visible]Impl implementations.
- Fix NEWT: Renamed setAutoDrawableClient(boolean) to setHandleDestroyNotify(boolean)
The semantic of
setAutoDrawableClient(boolean) defaults to false
was too complicated and specific, hence changed to
setHandleDestroyNotify(boolean) defaults to true
since its more clear and the name refers the window itself..
- Fix NEWT: Removed GLWindow's unused global window list
- Fix NEWT: Remove Window's unused event mask
- Rename com.jogamp.newt.impl.awt.AWTNewtFactory -> com.jogamp.newt.awt.NewtFactoryAWT
