Bug #16470 crash on grant if old grant tables
If a user upgraded the server without running mysql_upgrade, and later tried
to run a GRANT command on grant tables like tables_priv, the server would
crash.
This patch fixes this problem by checking if the grant tables were properly
initialized before attempt to store any new grants.
sql/sql_acl.cc@stripped, 2007-10-24 10:29:21+02:00, thek@adventure.(none) +3 -6
If grant_reload fails, don't try to store new GRANTs because the grant tables
weren't properly initialized.
