Hi
I have following piece of code in file f1.py
##### f1.py starts here #######
def f():
pass
def main():
import profile
profile.run('f()')
if __name__ == '__main__':
main()
# ------ end of f1.py ----
executing f1.py works as expected.
Now I have a file f2.py
##### f2.py starts here #######
import f1
f1.main()
# ------ end of f2.py ----
If I run f2.py
I get the error message:
. . . .
> File "C:\Python26\lib\profile.py", line 70, in run
> prof = prof.run(statement)
> File "C:\Python26\lib\profile.py", line 456, in run

> File "C:\Python26\lib\profile.py", line 462, in runctx
> exec cmd in globals, locals

So cProfile doesn't find my function f any more.
I can fix this by changing the code in f1.py to
profile.run('f1.f()')
However now I can't run f1.py anymore.
Is it intentional, that cProfile always uses the name space of the
initial module?
I consider it surprising especially as I did not find any mentioning of
this particularity in the documentation, which states:

I'm using python 2.6.5
The reason why I don't profile at the top level is, that I do not want
to profile some parts of the code and as I want to
conditionally profile a cetain function within different contexts /
applications
WI have also difficulties implementing something like this in a module,
which
is not the main module.
arg1 = f(1)
arg2 = f2()
if do_profile:
CProfile('result = function_name(arg1, arg2)', fname)
else:
result = function_name(arg1, arg2)
Any tips / suggestions??
