New submission from Hagen Fürstenau <[email protected]>:
A C function or method call without keyword arguments gets reported by
the profiler as expected (in the line with "{method 'sort' of 'list'
object}"):
>>> cProfile.run("[].sort()")
4 function calls in 0.000 CPU seconds
Ordered by: standard name
ncalls tottime percall cumtime percall filename:lineno(function)
1 0.000 0.000 0.000 0.000 <string>:1(<module>)
1 0.000 0.000 0.000 0.000 {built-in method exec}
1 0.000 0.000 0.000 0.000 {method 'disable' of
'_lsprof.Profiler' objects}
1 0.000 0.000 0.000 0.000 {method 'sort' of 'list'
objects}
However, once a keyword argument is given, the relevant line is missing:
>>> cProfile.run("[].sort(reverse=True)")
3 function calls in 0.000 CPU seconds
Ordered by: standard name
ncalls tottime percall cumtime percall filename:lineno(function)
1 0.000 0.000 0.000 0.000 <string>:1(<module>)
1 0.000 0.000 0.000 0.000 {built-in method exec}
1 0.000 0.000 0.000 0.000 {method 'disable' of
'_lsprof.Profiler' objects}
This happens with profile and cProfile in 2.6 and 3.0.
