-
DEBUG_COLLECTABLE Prints information on collectable objects found during collection
-
DEBUG_INSTANCES Meaningful only if
DEBUG_COLLECTABLEand/orDEBUG_UNCOLLECTABLEare also set: prints information on objects found during collection that are instances of classic Python classes-
DEBUG_LEAK The set of debugging flags that make the garbage collector print all information that can help you diagnose memory leaks, equivalent to the inclusive-OR of all other constants (except
DEBUG_STATS, which serves a different purpose)-
DEBUG_OBJECTS Meaningful only if
DEBUG_COLLECTABLEand/orDEBUG_UNCOLLECTABLEare also set: prints information on objects found during collection that are not instances of classic Python classes-
DEBUG_SAVEALL Saves all collectable objects to list
garbage(uncollectable ones are always saved there) to help diagnose leaks-
