Subject [jira] Created: (STDCXX-943) Inefficiency when retrieving strings from message catalog

Inefficiency when retrieving strings from message catalog
---------------------------------------------------------

                 Key: STDCXX-943
                 URL: https://issues.apache.org/jira/browse/STDCXX-943
             Project: C++ Standard Library
          Issue Type: Improvement
          Components: 22. Localization
    Affects Versions: 4.2.1
            Reporter: Travis Vitek
            Priority: Minor
             Fix For: 4.3
         Attachments: stdcxx-943.patch

A single call to {{\_STD::messages<T>::do_get()}} can call {{\_\_rw_manage_cat_data()}}
up to three times. Since each call involves a mutex lock/unlock, there are going to be some
wasted cycles. It would be nice to reduce this to one call. Perhaps the {{_RW::\_\_rw_get_message()}}
function could be changed to fill in a pointer to the {{\_STD::\_\_rw_locale}} that is kept
in the cache and the {{_RW::\_\_rw_get_locale()}} function could be removed.

For binary compatibility reasons, we may need to add an overload of {{_RW::\_\_rw_get_message}}
and deprecate the other functions so that they are removed automagically in the next major
release.
