STINNER Victor  added the comment:

Example:
---
import warnings
import tracemalloc

#tracemalloc.start(5)

# always log ResourceWarning messages
warnings.simplefilter("always", ResourceWarning)
def func():
f = open(__file__)
# emit ResourceWarning
f = None
func()
---

Output with Python 3.7:
---
$ python3 script.py
script.py:11: ResourceWarning: unclosed file <_io.TextIOWrapper 
name='script.py' mode='r' encoding='UTF-8'>
  f = None
---

Output with my attached PR 10486:
---
$ python3 script.py
script.py:11: ResourceWarning: unclosed file <_io.TextIOWrapper 
name='script.py' mode='r' encoding='UTF-8'>
  f = None
ResourceWarning: Enable tracemalloc to get the object allocation traceback
---

Finally, if tracemalloc is enabled:
---
$ ./python -X tracemalloc=5 script.py 
script.py:11: ResourceWarning: unclosed file <_io.TextIOWrapper 
name='script.py' mode='r' encoding='UTF-8'>
  f = None
Object allocated at (most recent call last):
  File "script.py", lineno 12
func()
  File "script.py", lineno 9
f = open(__file__)

(I did find https://docs.python.org/3/whatsnew/3.6.html#warnings, which was 
very helpful.)

2017-02-15 Thread STINNER Victor 

STINNER Victor added the comment:

To be clear: warnings should only suggest to enable tracemalloc if 
tracemalloc.is_tracing() is False.

It is possible to tracemalloc is tracing, but failed (for different reasons) to 
track where the memory of the resource was allocated.
