Ceph » rgw

I'm using librgw with new Ceph release 12.2.3, librgw will always get unexpected crush when it is processing a request, the following is the bug trace:

The main cause is in src/rgw/rgw_log.cc:360 :

std::string uri(s->info.env->get("REQUEST_METHOD"));

It seems "REQUEST_METHOD" is not initialized in librgw, neither do "HTTP_VERSION", "REQUEST_URI", "SCRIPT_URI", "SERVER_PORT", "REMOTE_ADDR". So I think we should initialized them before processing request in librgw
