Python in a Nutshell

Name

set_debug

Synopsis

set_debug(flags)

Sets the debugging flags for garbage collection. flags is an integer, a bit string composed by ORing (with Python’s normal bitwise-OR operator |) zero or more of the following constants exposed by module gc:

DEBUG_COLLECTABLE

Prints information on collectable objects found during collection

DEBUG_INSTANCES

Meaningful only if DEBUG_COLLECTABLE and/or DEBUG_UNCOLLECTABLE are 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_COLLECTABLE and/or DEBUG_UNCOLLECTABLE are 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

DEBUG_STATS

Prints statistics during collection to help tune the thresholds

DEBUG_UNCOLLECTABLE

Prints information on uncollectable objects found during collection
