i'm implementing message_filter/message_list profile variables for dsm
mod_sbc. i got it working, but i needed to convert req.method to lower
case before comparison, because when method list is created, its methods
are converted to lower case. in sbc/HeaderFilter.cpp readFilter:
vector<string> elems = explode(cfg.getParameter(cfg_key_list), ",");
for (vector<string>::iterator it=elems.begin(); it != elems.end(); it++) {
string c = *it;
std::transform(c.begin(), c.end(), c.begin(), ::tolower);
hf.filter_list.insert(c);
}
so i had to convert also in SBCCallLeg.cpp req.method to lower case
before method search.
original:
bool is_filtered = (it->filter_type == Whitelist) ^
(it->filter_list.find(req.method) != it->filter_list.end());
modified:
string c = req.method;
std::transform(c.begin(), c.end(), c.begin(), ::tolower);
bool is_filtered = (it->filter_type == Whitelist) ^
(it->filter_list.find(c) != it->filter_list.end());
how it is possible that the above original code has worked or has it?
