Verify test block remained local. Assign test block to a global variable. Verify test block became global. Clear global variable, assign test block to ivar. Loop: run generational collection verify block is scanned exactly once and age decrements by 1 until test block age becomes 0. Run a full collection (to clear write barriers). Verify block is scanned exactly once. Run a generational collection. Verify block *not* scanned. Clear test block ivar. Run generational collection. Verify block *not* scanned and *not* collected. Run a full collection. Verify block was collected. */ @interface BlockLifetime : AutoTestScript { BOOL _becameGlobal; BOOL _scanned; BOOL _collected; BOOL _shouldCollect; uint32_t _age; id _testBlock; vm_address_t _disguisedTestBlock; AutoTestSynchronizer *_testThreadSynchronizer; } @end
