- Use InterruptSource.Thread.create(..),
while reducing InterruptSource.Thread ctors to 3 variants.
- Use InterruptSource.Thread instead of java.lang.Thread where possible
- Use SourcedInterruptedException where possible
- SingletonInstanceServerSocket: start(), stop() and run()
- Persistent-Wait and Cancelable
- Add @since 2.3.2

interrupts original-owner, even if not waiting at unlock()
RecursiveThreadGroupLockImpl01Unfairish.unlock():
An interrupt() is always issued
from group members on the original owner.
This shall only happen, if the original owner is waiting
within unlock() for all group members to be unlocked.
This extra interrupt causes side-effects, see Bug 1211.
Only issue the interrupt to wake-up the original owner
iff waiting within unlock!
+++
RecursiveLockImpl01CompleteFair:
Issue 'Thread.interrupted()' to clear a slipped interrupt
call after while-loop.

Code Clean-Up based on our Recommended Settings (jogamp-scripting c47bc86ae2ee268a1f38c5580d11f93d7f8d6e74)
- Change non static accesses to static members using declaring type
- Change indirect accesses to static members to direct accesses (accesses through subtypes)
- Add final modifier to private fields
- Add final modifier to method parameters
- Add final modifier to local variables
- Remove unnecessary casts
- Remove unnecessary '$NON-NLS$' tags
- Remove trailing white spaces on all lines

Assume Lock
If timeout has been reached but the lock has been released, the lock has to be assumed.

- LockExt -> ThreadLock - clarifying semantics (API Change)
- ThreadLock: Remove isOwner(), use isOwner(Thread.currentThread)
- adding @Override

RecursiveLockImpl01Unfairish.Sync
RecursiveLockImpl01Unfairish changes are in preparation of RecursiveGroupThreadLock.
|
|
|
- RecursiveLock _is_ interface.
- Use LockFactory to create a RecursiveLock.
- Impl: RecursiveLockImpl01Unfairish
- just using notify w/o any queue: fast
- still enqueuing new lock-applicants if queue full (nice)
- lock's sync extends AbstractOwnableSynchronizer and uses it (monitor)
- Impl: RecursiveLockImpl01CompleteFair
- using queue and interrupt for correctness (slow)
- lock's sync extends AbstractOwnableSynchronizer and uses it (monitor)
- Impl: RecursiveLockImplJava5 for using Java5's concurrency impl.
- to verify correctness, performance and deviation of locking time
TestRecursiveLock01 new performance measurements incl. simple avrg and deviation
shows best combined performance-deviation w/ our RecursiveLockImpl01Unfairish
os Linux and MacOSX.
RecursiveLockImpl01Unfairish is the default in LockFactory.
Adding 'private' LockDebugUtil, allowing validating all holdings locks
of one thread as stack traces (Throwable).
Besides the AbstractOwnableSynchronizer utilization, this helps debugging deadlocks
and starvation very well.
