Add suspend count to thread implementation.
Increment suspend count on suspend and decrement on resume.
Wait on suspend count to be decremented to 0.
Return suspend count on suspend and on resume before incr/decr.
Fix naming of resume suspend count to make clear that suspend count is
before incr/decr.
Add test.
Shorten names to 16.
Rename Win32 to Windowing.
Shorten GraphicsSystem thread names due to 16 length limit of pthread.
Without this change, both show up as GraphicsSystem.
Remove redundant "Worker" and "Thread" from names.
Remove redundant thread handle from thread name.
Add thread local bool for alertable state.
Use real-time event interrupt to run callback.
Fix sleep duration from miliseconds (microseconds / 1000) to seconds in sleep
command.
Add note for future implementation.
Ignore real-time event 37 in .gdbinit which is used to signal callback.
Test AlertableSleep
Test Thread QueueUserCallback.
TODO: Test alerted wait result when using IO functions.
Use real-time event interrupt to communicate suspend in timely manner.
Use conditional_variable to implement suspend wait and resume trigger.
Ignore real-time event 36 in .gdbinit which is used to signal suspend.
Test suspending threads.
Test Manual Reset and Synchronization timers single threaded.
Test Cancelling timers.
Test WaitMultiple.
Ignore real-time event 35 in .gdbinit which is used to signal timer.
Callbacks don't seem to be called so testing them is difficult.
Keep track of recursive locks with owner and count of locks.
Only allow recursive locks from same thread and increment count.
Only allow first locks from when count is zero.
Test acquiring and releasing mutant on same and on different threads.
Test Release return values.
Test WaitAll and WaitAny.
Test acquiring and releasing semaphores on same and on different threads.
Test previous_count values.
Test WaitAll and WaitAny.
Add tests for invalid semaphore creation parameters but disactivated as
they do not pass on any platform. These should be enabled and the
implementations fixed to match documentation.
Add PosixConditionBase as base class for Waitables to use common
primitives mutex and conditional variable
Add abstract signaled() and post_execution() to use single WaitMultiple
implementation.
Remove file-descriptor specific wait implementation to PosixFdHandle class
which breaks on waits of non-fd handles.
Replace with PosixConditionHandle and extend to support auto reset and
initial values.
Simplify mutex and conditional variable use with stdlib versions which
wrap these primitives but provide better C++ interface.
Test Event and Reset
Remove atomic boolean in fence. Variable signaled_ is already protected
by mutex.
Remove wait loop with single predicate wait protected with mutex.
Add Fence Signal and Wait tests
Test signaling without waiting.
Test signaling before waiting.
Test signaling twice before waiting.
Test synchronizing threads with fence.
Few REQUIRES were used to test as there are no return codes.
A failing test may hang indefinitely or cause a segfault which would still
register as a fail.
Implement HighResolutionTimer for Posix by using native timers.
Callbacks are triggered with realtime interrupts if they are supported.
Create an enum to track user-defined interrupts as well as an initializer and
handler to register these interrupts per thread.
Add test cases for timers for both single and multiple.
Fix Sleep function to continue sleeping if interrupted by system.
Add local .gdbinit to ignore signal 34 which is used by high res timer
Add Sleep Test for 50ms.
Fix Sleep under linux that was using microseconds as nanoseconds.
Factor timespec creation to template function using div/mod and nanoseconds
from duration cast.
Test logical_processor_count() 3 times to test static return value stays
correct.
Run EnableAffinityConfiguration(). No asserts possible.
Test setting thread id, test using uint32_t max to reset.
Test setting thread name. No asserts possible.
Test running MaybeYield(). No obvious more complex test case.
Test running SyncMemory(). No obvious more complex test case.
Check TracerPid in /proc/self/status for attached debugger.
Add SIGTRAP handler to prevent signal from halting app while not running
in a debugger.
Log DebugPrint in clog (stderr).
