matching StaticConfig at runtime; Fix PPC (Bug 1056) and MIPSLE (Bug 1014) issues.
Currently the StaticConfig is being queried
via the key[OSType, CPUType ..]
as pre-determined by Java properties or the ELF parser.
This adds complication to maintain different platforms
and the key query might not even be sufficient.
The MachineDescriptor's StaticConfig only purpose shall be
to speed-up native data size and offset/alignment retrieval.
This is done by using the StaticConfig index within
all StaticConfig[]s as a lookup-index for the precomputed
struct's size and offset tables.
+++
Solution:
Rename: MachineDescriptor -> MachineDataInfo
Rename: MachineDescriptorRuntime -> MachineDataInfoRuntime
After having defined os.and.arch (OSType, CPUType and ABIType)
w/ the optional help of the now self containing ELF Reader (Bug 1125),
the native gluegen-rt library gets loaded enabling JNI methods.
It is satisfactory to retrieve MachineDataInfo
at runtime w/ JNI and find the matching/compatible StaticConfig.
Only in case none is found, the program needs to abort.
Otherwise the found MachineDataInfo.StaticConfig and MachineDataInfo
are stored for further use (see above).
This removes above complication and key to StaticConfig mapping.
New platforms simply need to add a new unique entry into the
StaticConfig[] table.
++
Also fixes Bug 1056 (PPC), thanks to tmancill [@] debian [.] org,
and Bug 1014 (MIPSLE), thanks to Dejan Latinovic.
Parts of the patch for Bug 1014 from Dejan Latinovic are included.

ELF Reader 'jogamp.common.os.elf' currently uses
Platform's pre-determined OS_TYPE and CPUType.
It also uses the host platforms MachineDescription,
hence can not read ELF files from other machines.
This also forbids Platform to determine CPUType etc
w/o having a valid 'os.arch' property.
+++
ElfHeader should be split in
- ElfHeaderPart1 (CPUType independent)
- ElfHeaderPart2 (CPUType dependent)
Fix shall make the ELF Reader self containing
by only using ELF CPUType data, etc.
This requires customization of struct parsing,
where MachineDescription.Static index shall be
- defined in ElfHeaderPart1 using e_Ident's CPUType.
- used in ElfHeaderPart2 and all its struct types.

Manu <[email protected]>:
In OpenJDK, Java version notation is a little different from Oracle JDK one:
OpenJDK uses "-u" instead of "_" to separate the version number from the update number, i.e. "1.7.0-u60-b04" vs "1.7.0_60-ea".
That would be nice to take this into account in the static initializer of jogamp.common.os.PlatformPropsImpl class. You could simply replace the line:
final int usIdx = JAVA_VERSION.lastIndexOf("_");
by:
final int usIdx = JAVA_VERSION.replace("-u", "_").lastIndexOf("_");
If you want to program it better, you can also test the "java.runtime.name" property that returns "OpenJDK Runtime Environment" for OpenJDK.
See also bug #944 https://jogamp.org/bugzilla/show_bug.cgi?id=944

'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

access (2)
- Completes 23341a2df2d2ea36784a16fa1db8bc7385351a12
- Replace 'DynamicLinker' interface w/ well documented one
- All DynamicLinker methods are now considered secure, i.e.:
- open/lookup and close utilize reference counting on handle via a hash map.
- lookupSymbol(..) and close(..) impl. validate the passed library handle
whether it's retrieved via open*.
This is the fast path, not that expensive.
- lookupSymbolGlobal(..) performs
Check acccess of 'new RuntimePermission("loadLibrary.*")' if SecurityManager is installed.
This is the slow path.
- DynamicLibraryBundleInfo now reflects the security requirements,
i.e. whether priviledged access is needed.

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(..) {}' !

- Property access
- File access
- Native library loading

May break GCJ/ECJ .. needs to be revised.
- Adding JAVA_6 in PlatformPropsImpl
- Buffers.isDirect() chooses fast-path iff JAVA_6, otherwise using reflection (GCJ/ECJ)
- Adding JAVA_6 info in VersionUtil
- API doc: Refine JAVA_SE and JAVA_6 spec.
TODO: In case GCJ etc is unable to compile the JAVA_6 code
even though it uses a static condition (probably not),
We have to wrap isStatic in an own class, one for JAVA_6 and one for <= 1.5.
This will be a good exercise for further issues we may have w/ Java <= 1.5.

static initialization interdependencies w/ the GlueGen native library loading
and it's derived information {@link #getMachineDescription()}, {@link #is32Bit()}, ..<br>
This mechanism is preferred in this case to avoid synchronization and locking
and allow better performance accessing the mentioned fields/methods.

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.

TempJarCache.bootstrapNativeLib(..) usage
- Moving to Platform solves former interdependencies between GlueGenJNILibLoader/Platform
- TempJarCache is being setup w/ bootstraping the gluegen-rt native lib jar file.
Interesting here is that when using Oracle's JRE w/ Applets/JNLP the
current dbg output is:
gluegen-rt: url-root http://risa/deployment/test/jau02s/jar/
gluegen-rt: nativeJarURL jar:http://risa/deployment/test/jau02s/jar/gluegen-rt-natives-linux-amd64.jar!/
gluegen-rt: nativeJar /home/sven/.java/deployment/cache/6.0/49/3c6d1e31-2c90f42e
IE the JRE implementation already deduces the online link to the Applet/JNLP cache.
This makes the implementation much simpler, ie. same for application and Applets/JNLP.
Have to verify w/ other Java impl. sure - and add same logic for the JOGL part.
