Changed NEWT NativeWindow creation contract
Original contract:
(1) A native window was created as soon as possible,
ie when NEWTFactory.createWindow(..) was called - if possible.
(2) A valid native window has to be created at least after setVisible(true)
has been called.
Problems:
Not all implementation are able to create the native window that early,
but at setVisible(true) only (e.g: KD and EGL).
Due to window parenting especially the new AWT/NEWT parenting,
the native window can only be created in case the parent native window is valid.
New contract:
(1) A native window is created at setVisible(true),
if it's a top level window or the native parent window is valid.
(2) A valid native window may not be created after setVisible(true)
has been called.
Subsequent setVisible(true) calls shall be made in case
the creation has not been done yet.
This is demonstrated in GLWindow.display() for example.
The new contract implements a lazy native window creation.
+++++
AWT/NEWT Parenting
- HierarchyListener and ComponentListener ensure that the NEWT child window
will be setVisible according to the AWT parent window.
- Lazy native window creation relaxes requirements to the parent window's state.
- Attachment of the child window and setVisible() may be called
after NEWT child window creation.
- GLWindow supports NEWT child window creation directly
The test case TestParenting01AWT.java reflect this new contract
and demonstrates more simplified and more flexible use cases.
+++++
NEWT Fixes:
- All NEWT implementation's native code method names end with 0.
- GLWindow: don't issue the actual 'init'/'display' call to GLEventListeners
in case the window is not visible.
- NEWT setSize/setPosition:
if native-window
call native-window action and let the attributes being set by
the feedback call, which issues more action, ie RESIZE.
else
set the attributes directly, no feedback call/action is necessary.
+++++
X11 Fixes:
- X11GLContext MakeContextCurrent:
Use MakeCurrent in case write and read drawable are equal,
otherwise SEGV happens on ATI with heavy multithreading involved!
Even XLockDisplay and XSync didn't help here ..
- X11GLXDrawableFactory shared resource:
Removed the resource holder thread to simplify code,
hence proper release is no more desired and it could become a cause for deadlock.
- Moved XInitThreads() from NEWT X11Window -> NativeWindow X11Util,
since NativeWindow is loaded first (essential for XInitThreads())
and it is the more basic lib.
- Made call to XInitThreads() conditional, ie it's spared if
AWT could be used - which causes SEGV .. (AWT bug). See X11Util.java
+++++
JOGL Fixes:
- GLProfile.isAWTAvailable() -> NativeWindowFactory.isAWTAvailable()
- GLProfile.isAWTJOGLAvailable() -> GLProfile.isAWTAvailable()

- See https://bugzilla.mozilla.org/show_bug.cgi?id=486277
- Calling XCloseDisplay occasionally leads to a SIGSEGV,
even thought the reference is valid and OK.
Workaround is not to close any X11Display,
but to hold them stashed and reuse them.
Since we already pipeline all X11Display's
via Nativewindow's X11Util, an added referenceCounter
and a global active/passive list solved this problem.
This workaround is only active in case 'isVendorATI()'.
NEWT/NativeWindow X11:
- Let XIOErrorHandler and invalid display references
fail hard with FatalError, otherwise we won't see
the stack trace - and those bugs are indeed fatal.
NativeWindow X11:
- Install XIOErrorHandler, which stays active.
- X11Util.X11Display:
- Add reference counter
- Add global active/passive list.
Passive if reference count == 0
and marked as 'un-closeable' (-> ATI).
Reusing passive members when create a new display.
-
JOGL:
- Use DeleteLocalRef() calls to free temp NIO buffer
in manual *Copied implementation.
- GLDrawableFactoryImpl: Be serious about the shutdown() semantics
- *GraphicsConfiguration:
- Fix the invalid Onscreen/PBuffer/Pixmap determination (X11/EGL/WGL)
- Just return null if not valid
- X11GLXGraphicsConfigurationFactory - FBConfig
- Determine recommendedIndex properly ..
- Don't bail out if a FBConfig is invalid ..
- Use Chooser in case nothing is recommended ..
- X11OffscreenGLXDrawable fixes bugs:
- wrong (int) cast of parent window in XCreatePixmap call
- setting display to zero too early in destruction, ie
before XCloseDisplay
- X11GLXDrawableFactory is using [singleton] shared dummy resources for
- Screen, Drawable and Context
which are utilized in case they are needed ..
They are removed at shutdown call
- GLXVersion gathering in GLXUtil now ..
- DefaultGLCapabilitiesChooser: Respect PBuffer selection
Tests:
- Add DrawableFactory shutdown()
- Add various Offscreen Capabilties
- Add Offscreen and non-pbuffer case
- JUnit Passed (Linux64bit: NVidia/ATI)
- demos.jrefract.JRefract passed (Linux64bit: NVidia/ATI)

Due to limitations on Windows,
we need to standardize the one thread for
- window creation, and
- event dispatching
This was already mentioned in the previous implementation
but while integrating into another threading model (Plugin3),
it turned out that manual managing the thread is too much of a burden.
NEWT now uses a EDT per Display and Thread as the default,
where Display creation, Window creation and event dispatching is 'pipelined' into.
This can be switched off:
NewtFactory.setUseEDT(boolean onoff);
and queried via:
NewtFactory.useEDT();
Note this EDT impl. does not implicate a global lock or whatsoever.
The experimantal semantics of a current GL context
for input event dispatching is removed,
i.e. the GL context is no more made current for mouse/key listener.
This reduces the complexity and allows the proper impl. of
the external dispatch via EDT .. for example.
Removed:
GLWindow: setEventHandlerMode(int) .. etc
X11Display: XLockDisplay/XUnlockDisplay
needed to be utilized to allow the new
multithreading (EDT/Render) Display usage.
X11Window: lockSurface/unlockSurface
locks X11Display as well ..
+++++
NEWT: 'getSurfaceHandle()' semantics changed.
To allow usage of the surfaceHandle for OS
where it is allocated thread local (MS-Windows),
it shall be aquired/released while lockSurface/unlockSurface.
This is done in the Windows Window implementation.
GLWindow can no more query 'getSurfaceHandle()'
to verify if 'setRealized()' was successful.
NEWT: Window surface lock is recursive and blocking now,
as it shall be.

The current thread default display or
the given display is being used,
hence it is no more required to use a ToolkitLock
for X11 without AWT.
Removed X11 ToolkitLock in case of X11 without AWT,
which is being detected with the absence of the classes
java.awt.Component _AND_ javax.media.nativewindow.awt.AWTGraphicsDevice
or with the system property
java.awt.headless=true
Only in the Java2D/Swing case, one 'leaking' Display
is created within canCreateGLPbuffer().
- Workaround for Hotsport bugs #4395095, #6852404
4395095 JNI access to java.nio DirectBuffer constructor/accessor
6852404 Race condition in JNI Direct Buffer access and creation routines
- Added build.xml
-Dbuild.noarchives=true property to skip the time consuming
creation of zip archives.
