Dispatcher Objects Rewrite (minus Queues, coming in next patch). Global Changes: - Use KOBJECT enumerations for all objects, remove obsoleted ros-internal enumeration. - Reformatting, commenting, and addition of Debug Prints for easier debugging - Properly create Executive Objects. They don't need a creation routine. - Make sure to properly lock and release the Dispatcher Database. Mutex/Mutant: - Correct MUTANT_BASIC_INFORMATION - Return previous state in Kernel Functions, intead of 1 or 0 all the time. - Initialize listhead properly - Removed code duplication between mutant and mutex release. - Fix bugs in release - Add proper exeption if the mutex is not owned. Kernel Queues: - Optimize the code - Use Inserted Flag Timers: - Some changes in setting the default data to allow KiInsertTimer to be called internally by the wait code in the next patch. Events: - Optimize and simplify KeInitializeEvent - Implement KeInitializeEventPair - Fix KePulseEvent. It was completely messed up and also used unneeded Interlocked function. - Fix KeResetEvent. It was not locking the dispatcher lock but using Interlocked. - Fix KeSetEvent. It was not differentiating between Notification and Sycronization events and also signaling the Event even if nobody was waiting on it. Semaphores: - Fix KeReleaseSemaphore. It was not checking if nobody was waiting on it before unwaiting the thread. - Fix not releasing dispatcher database before raising an exception. - Add check to NtCreateSemaphore to make sure the counts make sense. Event Pairs: - Remove Thread Event Pair. They are only used for NT4 QuickLPC which is obsoleted. - Use KeInitializeEventPair svn path=/trunk/; revision=14045 |
