New submission from Rohan D'Sa <[email protected]>:
import gc, json
class leak(object):
def __init__(self):
pass
gc.set_debug(gc.DEBUG_LEAK)
while True:
leak_ = leak()
json.dumps(leak_.__dict__, indent=True)
gc.collect()
print(f"garbage count: {len(gc.garbage)}")
Using the following code under Python 3.6.3, the garbage count keeps increasing
and windows task manager records steady memory increase.
However without indent json.dumps(self.__dict__), no leak is observed.
