and privileged access)
This review focuses on how we perform permission checks,
or better - do we circumvent some assuming full privileges ?
Some native methods do need extra permission validation, i.e. loading native libraries.
Further more AccessController.doPrivileged(..) shall not cover generic code
exposing a critical feature to the user.
Further more .. we should rely on the SecuritManager, i.e. AccessControlContext's
'checkPermission(Permission)' code to comply w/ fine grained permission access.
It is also possible to have full permission w/o having any certificates (-> policy file).
+++
We remove implicit AccessController.doPrivileged(..) from within our trusted code
for generic methods, like Property access, temp. files.
+++
SecurityUtil:
- Remove 'getCommonAccessControlContext(Class<?> clz)',
which returned a local AccessControlContext for later restriction
if the passed class contains all certificates as the 'trusted' GlueGen class has.
- Simply expose convenient permission check methods relying on
SecurityManager / AccessControlContext.
PropertyAccess:
- 'protected static void addTrustedPrefix(..)' requires AllPermissions if SecurityManager is installed.
- Remove implicit doPrivileged(..) triggered by passed AccessControlContext instance,
only leave it for trusted prefixes.
IOUtil:
- Remove all doPrivileged(..) - Elevation shall be performed by caller.
DynamicLinker:
- 'public long openLibraryLocal(..)' and 'public long openLibraryGlobal(..)'
may throw SecurityException, if a SecurityManager is installed and the dyn. link permission
is not granted in the calling code.
Implemented in their respective Unix, OSX and Windows manifestation.
Caller has to elevate privileges via 'doPrivileged(..) {}' !
+++
Tests:
- Property access
- File access
- Native library loading
Manual Applet test (unsigned, but w/ SecurityManager and policy file):
> gluegen/test/applet
Applet has been tested w/ signed JAR w/ Firefox and Java7 on GNU/Linux as well.
Manual Application test (unsigned, but w/ SecurityManager and policy file):
com.jogamp.junit.sec.TestSecIOUtil01
- Run w/ SecurityManager and policy file:
- gluegen/scripts/runtest-secmgr.sh
- Run w/o SecurityManager:

Manifest ; Common jogamp_int_version for Android.
Until 2.0.2 gets released, the version string is 2.0.2-rc-<TIMESTAMP>
and used in the Manifest for IMPLEMENTATION_VERSION.
The previous build version name of IMPLEMENTATION_VERSION
goes into the new tag IMPLEMENTATION_BUILD.
Further more, we use a common jogamp_int_version for Android, to make life more easy.

binding initialization
- OSX/Java7 w/o 32bit tests
OSX/Java7 has no 32bit JVM, disable d32 tests for such, using property 'use.macosx32'
- Reliable Test1p*JavaEmitter JNI binding initialization
Load libs and init JNI binding statically w/ @BeforeClass,
since OSX/Java7 for some reason gets confused (?) w/ init sequence.
This is no issue for JOGL etc .. as far we have observed.

- NativeLibrary Fix
- enumerateLibraryPaths(..):
- Properly iterate through all prefix _and_ suffix.
- Make public for JNILibLoaderBase.loadLibraryInternal(..)
- isValidNativeLibraryName(..):
- Stop iterating through prefix, if previously found
but suffix doesn't match.
- JNILibLoaderBase.loadLibraryInternal(..) Enhancement
- Mark customLibLoader FIXME: remove (we will get rid of jnlp.launcher.class)
- If System.load(TempJarCache) and System.loadLibrary(plainLibName) fails,
use NativeLibrary.enumerateLibraryPaths() w/ System.load(..) as last resort.
Tested on Linux x86_64 Java6 and OSX Java7 manually, no regressions expected.

JNILibLoaderBase.addNativeJarLibs(..): Add API doc
JNILibLoaderBase:
"addNativeJarLibs(Class<?> classFromJavaJar, String allNativeJarBaseName, String[] atomicNativeJarBaseNames)" ->
"addNativeJarLibs(Class<?>[] classesFromJavaJars, String singleJarMarker, String[] stripBasenameSuffixes)"
Derive the 'all' (1st choice) native JAR URL solely on the given class's JAR URL.
Examples:
JOCL:
// only: jocl.jar -> jocl-natives-'os.and.arch'.jar
addNativeJarLibs(new Class<?>[] { JOCLJNILibLoader.class }, null, null );
JOGL:
final ClassLoader cl = GLProfile.class.getClassLoader();
// either: [jogl-all.jar, jogl-all-noawt.jar, jogl-all-mobile.jar] -> jogl-all-natives-<os.and.arch>.jar
// or: nativewindow-core.jar -> nativewindow-natives-<os.and.arch>.jar,
// jogl-core.jar -> jogl-natives-<os.and.arch>.jar,
// (newt-core.jar -> newt-natives-<os.and.arch>.jar)? (if available)
final String newtFactoryClassName = "com.jogamp.newt.NewtFactory";
final Class<?>[] classesFromJavaJars = new Class<?>[] { NWJNILibLoader.class, GLProfile.class, null };
if( ReflectionUtil.isClassAvailable(newtFactoryClassName, cl) ) {
classesFromJavaJars[2] = ReflectionUtil.getClass(newtFactoryClassName, false, cl);
}
JNILibLoaderBase.addNativeJarLibs(classesFromJavaJars, "-all", new String[] { "-noawt", "-mobile", "-core" } );
Efficiency / Performance:
- Reduced JAR URL lookup calls JarUtil.getJarURL(..) - JNILibLoaderBase, Platform, JarUtil
- Attempt loading Jar files (native, class, ..) only once - TempJarCache
Code Cleanup (IOUtil, JarUtil, :
- IOException if not found
- IllegalArgumentException if null argument

Android specific classes for non Android platforms
Ensure same Java JAR content regardless of build target (fix).
Separate Android compilation results to gluegen-rt-android.jar,
avoiding generating different content of gluegen-rt.jar w/ non android builds.
aapt.signed: @{android.abi} argument is 'generic' by default.
Adding ${android.abi} to APK target name (gluegen-rt-android-armeabi-v7a.apk)
if not generic.

Android ClassLoaderUtil cleanup;
- Add 'asset' URLConnection
- Please read API doc 'PiggybackURLConnection' and 'AssetURLConnection'
- Solves generic resource handling where platform locations may differ,
ie ClassLoader lookup on Android in the 'assets/' subfolder.
- New Android 'AssetDexClassLoader' uses 'assets/' folder for findResource(..)
- aapt.signed (our APK ant task)
- uses 'assets/' folder
- adds the 'assetsdir' attribute allowing to copy other assets into the APK
- IOUtil uses URLConnection / incr. effeciency
- using URLConnection on all getResource(..) since URL
is connected anyways for validation and URLConnection can be used by caller right away
- String getRelativeOf(URL, String) -> URL getRelativeOf(URL, String)
- preserves scheme, authority, etc
- simple parentOf handling, more efficient
- reusing new 'asset' protocol impl.
- Android ClassLoaderUtil cleanup;
- Use createClassLoader(..) impl for build-in static jogamp and user APKs,
which removes code redundancy
Tests: New code path, especially 'assets' are covered by new unit tests, no regressions on Linux.

ActivityLauncher provides delegating Activities, allowing the user to:
- daisy chain custom APK classes and native libraries to the classpath
- name one custom activity which gets delegated to, the downstream activity
Overview:
[User:a1] -- (usr-data) --> [Launcher] -> [User:a2] + using [other packages..]
[User APK] - The user provided APK
[JogAmp APK] - JogAmp APKs
[User:a1] - The initial user activity, which starts the [Launcher].
Providing data to [Launcher]: [User:a2], [User APK]
Resides in [User APK]
[User:a2] - The actual downstream 'real' activity, spoiled w/ full fledged ClassLoader
having access to all packages as requested, ie. [User APK], ..
Resides in [User APK]
[Launcher] - The launcher activity.
Gets called by [User:a1].
Creates a new ClassLoader, daisy chainging all requested APKs.
Instantiates [User:a2] w/ new ClassLoader.
Delegates all calls to [User:a2].
Resides in [JogAmp APK].

explicit BOOTCLASSPATH, use default.
(2) Android 4.0.3 LEB 12.02 / Pandaboard requires the original BOOTCLASSPATH,
otherwise dependencies are broken and dalvikvm crashes.
Adding 'our' ant-junit-all.apk to 'complete' the set of our required junit/ant classes
seems to work well on V. 2.3.6 (Samsung Galaxy S) and V. 4.0.3.

- A bug in cpptasks was getting in the way of a working build with NDK
r7. A local patch to cpptasks fixed the bug.
- The patch is added as make/lib/cpptasks_gcclinker.patch and applies
cleanly to cpptasts @ revision 177.
- The result of building cpptasks r177 with this patch is part of the
commit as well.
- Cleaned up and simplified the android cross-compile script in
make/scripts.
- Cleaned up arguments passed to gcc for compiling and linking to look
more like the command lines used for building NDK samples.
- Some differences are necessary as cpptasks won't let us specify any
binary other than 'gcc' for building. See
gluegen-cpptasks-android-armv7.xml for comments on the matter.
- Thinking forward to x86 support, generalized jogamp-androidtasks.xml
to install the gluegen shared library in a subdirectory of image/lib
named for the targetted ABI for packaging with aapt. This file is
no-longer ARM-specific.

Current minimum requirements are:
- Java 1.6 (Level 6.0)
- Android SDK API Level 9 (Version 2.3 Gingerbread)
Official production builds are performed w/ Java 1.6.
- Java 1.6 (Level 6.0)
- Android SDK API Level 9 (Version 2.3 Gingerbread)
Android supports Java language level 6.0.
Nevertheless, it cannot be guaranteed whether the Android API
supports all classes and methods of Java 1.6.
It is required for JogAmp developers to validate Android compatibility
by an Android crosscompilation build.
Current GlueGen code utilizes some minor Java 1.6 features
which could be replaced, however it's not desired at this point
since we have no mode hard Java 1.5 constraints.
Notes:
- On OS X 10.5.8, only the 64bit version of Java6 is available
and hence the only supported one on Leopard.

Pushing determination of host (compiletime) and target (runtime) Java version
to 'jogamp-env.xml'.
jogamp-env.xml uses:
env: SOURCE_LEVEL -> propery: target.sourcelevel def.: ${ant.java.version} >=1.6 (!)
env: TARGET_LEVEL -> propery: target.targetlevel def.: ${ant.java.version} >=1.6 (!)
env: TARGET_RT_JAR -> propery: target.rt.jar def.: ${java.home}/lib/rt.jar
Either all above values are set, or none at all (default),
otherwise a build error is being thrown.
Further more we have the compiletime properties:
host.sourcelevel def.: ${ant.java.version} >= 1.6 (!)
host.targetlevel def.: ${ant.java.version} >= 1.6 (!)
host.rt.jar def.: ${java.home}/lib/rt.jar

- Preparation.
Currently GlueGen fails for type long (size) and some alignments (see package.html).
- The size and alignment values shall be queried at runtime.
- Compound alignment needs to follow the described natural alignment (also @runtime).
-
- Build
- add Linux Arm7 (EABI)
- junit test
- added compound/struct tests, pointing out the shortcomings of current impl.
- package.html
- Added alignment documentation
- remove intptr.cfg
- add GluGen types int8_t, int16_t, uint8_t, uint16_t
- move MachineDescription* into runtime
- Platform
- has runtime MachineDescription
- moved size, .. to MachineDescription
- use enums for OSType, CPUArch and CPUType defined by os.name/os.arch,
triggering exception if os/arch is not supported.
This avoids Java String comparison and conscious os/arch detection.
- MachineDescription:
- compile time instances MachineDescription32Bits, MachineDescription64Bits
- runtime queried instance MachineDescriptionRuntime
- correct size, alignment, page size, ..
