Hagen Fürstenau <hfuerste...@gmx.net> added the comment: I found the reason for this problem: C function calls with keyword arguments follow a different path than those without keywords in the function "call_function" of ceval.c. They end up being handled by "do_call", but there the call is not wrapped by C_TRACE, so a profiler function registered through sys.setprofile() doesn't see such calls.
The same problem occurs in "ext_do_call", which gets called in the handling of the opcodes CALL_FUNCTION_VAR and CALL_FUNCTION_KW, causing omission of a function call like >>> [].sort(**{'reverse':True}) from the profiler report. The attached patch solves the problem, but I don't know if it's the best solution. Handling calls with keyword arguments at the beginning of "call_function" seems to have bigger performance drawbacks though. ---------- keywords: +patch Added file: http://bugs.python.org/file13146/ceval.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5330> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
