hash_table does not require C++11 support in the compiler and, at least in theory, does not have unknown compatibility problems with Squid code (such as frequently hitting worst-case search or update scenarios). On the other hand, hash_table does not work well with C++ objects. > Would it be useful to refactor from one to the other while waiting > such as now? Do all compilers we care about support std::unordered_map? If yes, switching to a standard, C++-friendly class would be useful. However, there are other, more useful projects available if you are looking for something fun to do (and new code can use std::unordered_map if you declare it supported). HTH, Alex.
