access permission on Windows via BATCH file execution
Try using explicit call to Windows 'cmd.exe' w/ referencing the BATCH file location,
via
'Runtime.getRuntime().exec(new String[] { "cmd", "/c", "a.bat" } );'
While the bug itself could not be reproduced here,
I could test on Windows 7 (64bit and 32bit), as well as an WindowsXP 32bit
that no regression occured.

OutputStream impl.
Added MappedByteBufferOutputStream as a child instance of MappedByteBufferInputStream,
since the latter already manages the file's mapped buffer slices.
Current design is:
- MappedByteBufferInputStream (parent)
- MappedByteBufferOutputStream
this is due to InputStream and OutputStream not being interfaces,
but most functionality is provided in one class.
We could redesign both as follows:
- MappedByteBufferIOStream (parent)
- MappedByteBufferInputStream
- MappedByteBufferOutputStream
This might visualize things better .. dunno whether its worth the
extra redirection.
+++
MappedByteBufferInputStream:
- Adding [file] resize support via custom FileResizeOp
- All construction happens via ctors
- Handle refCount, incr. by ctor and getOutputStream(..), decr by close
- Check whether stream is closed already -> IOException
- Simplify / Reuse code
MappedByteBufferOutputStream:
- Adding simple write operations

on unix and osx)
Tested on Window 7 and Windows 8.1 using 'Using Software Restriction Policies',
i.e. disabled sw-execution in TEMP dir.
On Windows we need to add min. shell code, here 'echo off',
allowing the bat file to be executed if policy allows it.
Reminder: We test the following temp folder
1) java.io.tmpdir/jogamp
2) $XDG_CACHE_HOME/jogamp
3) $TMPDIR/jogamp or $TEMP/jogamp
4) $HOME/.jogamp
+++
Misc:
Proper 'duplicate' validation via 'file1.equals(file2)' test
using the abstract pathname.

and string (code generation)
Enhance compound access as delivered by Bug 1022,
to also generate accessors (getter and setter) for
array, pointer and string types.
Allow configuration of array length either via
their internal size (c-header) or config 'ReturnedArrayLength'.
'ReturnedArrayLength' allows specifying a java expression.
Canonical field names of compounds are _now_ specified as
follows for configuration entries:
COMPOUND.FIELD
e.g.
StructA.fieldB
Also allow configuration of pointer fields to be treated as
referenced arrays via 'ReturnedArrayLength'.
Further, allow specifying 'pointer fields' as String values
via 'ReturnsString' configuration.
++++
Implementation details:
- handle above described accessor features
- enhance JavaDoc for generated accessors
- generate native JNI compound and string accessor on demand
- encapsule accessor code generation in their own methods
- enhance exception messages
- enhance type verbosity in debug mode
- verbose debug output via GlueGen.debug()
Tests:
- Features covered by test1.[ch]
and Test1p1JavaEmitter and Test1p2ProcAddressEmitter
- Validated compilation and unit tests for modules:
- joal
- jogl (minor config changes req.)
- jocl (minor config changes req.)

'best' ABI
- Use 'os.arch' as a prelim CPUType for MachineDescription
- Always attempt to load a binary and parse it's elf header
- Linux: self-exe
- Android: gluegen-rt library
- Other: java lib
- Always use details (ABI) if ARM
- Android: Check CPU_TYPE and CPU_TYPE2
// FIXME / HACK:
// We use sCPUType for MachineDescriptionRuntime.getStatic()
// until we have determined the final CPU_TYPE, etc.
// MachineDescriptionRuntime gets notified via MachineDescriptionRuntime.notifyPropsInitialized() below.
//
// We could use Elf Ehdr's machine value to determine the bit-size
// used for it's offset table!
// However, 'os.arch' should be a good guess for this task.
Tested manually on
- Linux x86, x86_64, armhf (raspi)
- Android intel and arm
- Windows x86_64
- OSX x86_64

converting to file-path or URI (Windows UNC / share host)
Note: Authority for 'file-scheme' URI's is used on Windows to denote the host of the shared resource -> UNC
Following methods of IOUtil didn't consider the authority for file-scheme URI:
'URL toURL(final URI uri)'
'String decodeURIToFilePath(final String uriPath)'
'String decodeURIIfFilePath(final URI uri)'
Further more, the patterns 'patternSingleFS' and 'patternSingleBS'
converted multiple '\' '/' to one replacement.
However, we should not change the separator count and replace them one-by-one.
TestIOUtilURIHandling:
- Added shared-file-host 'filehost' test cases to file URIs and plain file path tests.
- Passed on Unix and Windows.
Added 'make/scripts/test-win32-smb_share.bat'
- Testing actual windows share usage
- Passed on Windows

/proc/self/exe (Linux) or a found java/jvm native lib.
- PlatformPropsImpl.queryABITypeImpl: Check Elf Header for ARM + !ANDROID (i.e. add other OS than Linux, use native java/jmv lib)
- NativeLibrary.enumerateLibraryPaths: Add 'sun.boot.library.path' to enumeration!
- TestElfReader01: Add test for finding java/jvm native lib and parse it

- Fin
MachineDesction == MD
MD.StaticConfig:
- enum for all supported static configs (ID -> MD)
- verified at runtime: test runtime queried-MD versus static-MD,
hard fail if not compatible (size/alignment)
SizeThunk primitive sizes:
- Add notion of fixed native size (eg. int64_t) and otherwise (eg. long)
java struct 'wrappers' code generation:
- single class using size/offset arrays of all MachineDescription configurations
- at runtime the array idx is queried in static block
- type aligment for not fixed-native-size types (SizeThunk, undef long/int) via StructAccessor
junit test:
- add float test
- fix native code
- add java (create, write) -> native (verify) test
works (tested) on: linux 32/64 and windows 32/64
