From fff31ca72cd9ce32ff8a59a9de045dcc035fbaa3 Mon Sep 17 00:00:00 2001 From: Antonio Cuni Date: Wed, 8 Nov 2017 22:53:30 +0100 Subject: [PATCH 01/14] change the interface between vmprof.enable and _vmprof.enable: the idea is that all the optional arguments are passed as kwargs, and that _vmprof.enable returns a dictionary of the args which it did not understood. This should make it easier to add new options without going out of sync with the PyPy backend, and will let vmprof.enable() to emit warnings if you pass options which are not understood by the backend --- src/_vmprof.c | 68 ++++++++++++++++++++++++++++++------- vmprof/__init__.py | 9 +++-- vmprof/test/test__vmprof.py | 34 +++++++++++++++++++ 3 files changed, 97 insertions(+), 14 deletions(-) create mode 100644 vmprof/test/test__vmprof.py diff --git a/src/_vmprof.c b/src/_vmprof.c index f96feb20..cc5f116e 100644 --- a/src/_vmprof.c +++ b/src/_vmprof.c @@ -163,7 +163,41 @@ static void cpyprof_code_dealloc(PyObject *co) Original_code_dealloc(co);
