Bug description:inconsistent interface for async
Description:
------------
It's not possible to get the results of an async query in an
user-extended mysqli_result.
For synchronous queries you could do:
class DatabaseResult extends mysqli_result {}
$r = mysqli_real_query($link, $query);
$o = new DatabaseResult($link, MYSQLI_STORE_RESULT);
For async the API is limited to mysqli_query() and
mysqli_reap_async_query(). mysqli_reap_async_query() not only calls
mysqlnd_reap_async_query(), but also
mysql_store_result()/mysql_use_result(). Therefore the mysqli_result
constructor is not usable.
Possible solutions:
1) Optional argument to mysqli_reap_async_query() to only call
mysqlnd_reap_async_query() but not
mysql_store_result()/mysql_use_result() - not elegant but small fix
2) mysqli_query() should save async case; mysql_store_result() &
mysql_use_result() should call mysqlnd_reap_async_query() automatically;
remove mysqli_reap_async_query()
Workaround now (overhead of SELECT 1 query):
$r = $link->multi_query('SELECT 1;'.$query);
$link->use_result()->free();
// do sth. else (async)
$link->next_result();
$o = new DatabaseResult($link, MYSQLI_STORE_RESULT);
