Alright, this should give some improved performance :)
This is the end of random seek access to rows. If you have a compelling reason as to why they should stay, contact me. Else, they are gone forevermore...
The following API calls are deprecated:
acm::sql_rowseek() -> no replacement
$db->sql_fetchfield($field, $rownum = false, $query_id = false) -> $db->sql_fetchfield($field, $query_id = false)
Initial tests show that phpBB3 over four percent of memory against phpBB3.1 on an empty board. So far so good :)
Other cool things:
db2, MS SQL ODBC and MS SQL 2005 all use less memory because they do not need to reference the last executed query to handle random access seeks :)
P.S.
The crazy people using SVN: please report any issues with the new way we itterate through caches, I do not want to miss anything :)
