Summary [Qt] Implement IncrementalSweeper and HeapTimer
Allan Sandfeld Jensen
Reported 2012-12-04 07:11:10 PST
The IncrementalSweeper performs continous garbage collection as opposed to prompted or forced garbage collection. It relies on HeapTimer which has only been implemented for Mac and Blackberry. Once HeapTimer has been implemented which should also be able to implemented opportunistic garbage collection.

Note the thread-moving code has not been tested. I am unsure under which conditions it would happen.

Comment on attachment 177477 [details] Patch I found the first couple of multithreading issues. Not least of which that QBasicTimer depends on a QThread.

Created attachment 177495 [details] Patch Use postEvent instead of startTimer, and ensure we create the event-dispatcher on construction.

See also comments in bug #95923 - it sucks that there's so much #ifdeffery for a little bit of platform specific timer code ;( Is it perhaps time to have HeapTimerCF, HeapTimerQt and HeapTimerEFL.cpp?

Created attachment 181678 [details] Patch Split HeapTimer.cpp into platform specific source files. The Mac build is missing an update.
