pstats.Stats.get_stats_profile can't handle functions with the same name

Bug report

Bug description:

MCVE

import cProfile
import time
import pstats


class A:
    def foo(self):
        time.sleep(1)


class B:
    def foo(self):
        time.sleep(2)


pr = cProfile.Profile()
pr.enable()
A().foo()
B().foo()
pr.create_stats()

ps = pstats.Stats(pr).sort_stats("cumtime")
ps.print_stats(5)

when I ran this in a jupyter notebook, this outputted:

         61 function calls in 3.003 seconds

   Ordered by: cumulative time
   List reduced from 21 to 5 due to restriction <5>

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        3    0.000    0.000    3.003    1.001 /usr/local/my_venv/lib/python3.10/site-packages/IPython/core/interactiveshell.py:3424(run_code)
        3    0.000    0.000    3.002    1.001 {built-in method builtins.exec}
        2    3.002    1.501    3.002    1.501 {built-in method time.sleep}
        1    0.000    0.000    2.002    2.002 /usr/tmp/ipykernel_104016/1099215389.py:12(foo)
        1    0.000    0.000    1.000    1.000 /usr/tmp/ipykernel_104016/1099215389.py:7(foo)

which correctly shows two different versions of a function called foo. However, due to the API design of get_stats_profile, only one of the functions will be stored in the dict FunctionProfile.func_profiles, the one which is last in the insertion order, which in this case since I sorted by cumtime will be A.foo:

print(ps.get_stats_profile().func_profiles["foo"])

outputs:

FunctionProfile(ncalls='1', tottime=0.0, percall_tottime=0.0, cumtime=1.0, percall_cumtime=1.0, file_name='/usr/tmp/ipykernel_104016/1099215389.py', line_number=7)

Maybe get_stats_profile should key the func_profile dictionary on something that's actually unique per profile entry, like filename:lineno(function)?

Commencez par pstats.Stats.get_stats_profile et examinez comment FunctionProfile.func_profiles est alimenté et indexé. Reproduisez la MCVE fournie avec A.foo et B.foo, puis vérifiez que les deux fonctions portant le même nom restent distinguables dans les données de profil renvoyées.
