I answer my own question ;-).
Here after the correct modification to make in evhttp_handle_request.
in http.c->evhttp_handle_request
"
if (p == NULL)
- res = strcmp(cb->what, req->uri) == 0;
+ res = strncmp(cb->what, req->uri, strlen(cb->what)) == 0;
else
res = strncmp(cb->what, req->uri,
- (size_t)(p - req->uri)) == 0;
+ strlen(cb->what)) == 0;
if (res) {
(*cb->cb)(req, cb->cbarg);
"
I've included it within my python bridge to libevent and it works great.
(I'm progressing with C).
I'm already able to use python function as http_event callbacks.
Next steps is to make them WSGI compliant ;-).
