[issue32045] Does json.dumps have a memory leak?
Rohan D'Sa <roh4n@gmail.com> added the comment: you are right. i realized later i actually had a leak in a com instantiated object, assumed it was a leak in the python and tried to find it using the gc module. The gc documentation led me down the garden path. QUOTE gc.garbage A list of objects which the collector found to be unreachable but could not be freed (uncollectable objects). UNQUOTE i assumed: - cyclic references are unreachable but can be freed and hence collectable. - __del__ finalizer (with cyclic references?) objects are unreachable and cannot be freed and hence uncollectable. -- ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32045> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

New submission from Rohan D'Sa <roh4n@gmail.com>: 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. -- components: Library (Lib) messages: 306344 nosy: rohandsa priority: normal severity: normal status: open title: Does json.dumps have a memory leak? versions: Python 3.6 ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32045> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
