[Cppcms-users] [Feature request]Returnning pointers to, not instances of, map/multimap

[<cn...@gr...>]

Hello! Artym,
 


Cppcms' performance might be boosted if methods returning map or multimap like

 
http::request()::get()
http::request()::post()
http::request()::cookies()
and http::request()::getenv()
 
are revised to return pointers to map/multimap. They are currently implemented to return instances of map/multimap holding elements. If they can be revised to return pointers to map/multimap, a lot of CPU and memory will be saved.
 
Another bonus from these pointers is that they are less error prone to users like me. I happened to write the following wrong code:
 
for(map<string,string>::const_iterator i=request().getenv().begin();i != request().getenv().end();++i)
  BOOSTER_LOG(debug,"env name/size") << i->first << "/" << i->second;
 
The problem here is that i refers to many different instances of maps, and this leads CPU to wander.  I would not have made this mistake if request().getenv() returned pointer to map.
 


Please pardon me if this is a bad request.

CN
