Hi,

I uses shared.DICT to store some key value pairs. When the size limit is reached and new items are inserted, some old items will be replaced. Is it possible to print log when the replacement happens?

Thanks

ngx_http_lua_shdict_expire (https://github.com/openresty/lua-nginx-module/blob/master/src/ngx_http_lua_shdict.c#L249) returns the number of keys that it removed, so it would be easy to write a small patch that writes log entries when this occurs. But it's not currently available now.
