Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment:
indent=True just makes json to use Python implementation instead of C
implementation. Python implementation uses closures which reference one other.
Simple example not involving json is:
import gc
def f():
def g():
return h
def h():
return g
return
gc.set_debug(gc.DEBUG_LEAK)
while True:
f()
gc.collect()
print(f"garbage count: {len(gc.garbage)}")
The "leak" is caused by using gc.set_debug(gc.DEBUG_LEAK). gc.DEBUG_LEAK
includes gc.DEBUG_COLLECTABLE, gc.DEBUG_UNCOLLECTABLE and gc.DEBUG_SAVEALL.
gc.DEBUG_SAVEALL causes garbage-collected objects to be saved in gc.garbage for
inspection. In normal circumstances they are collected.
