If the authenticator option is enabled, no users are loaded and no errors
have occurred in the user loading process, the service credentials are
injected.
When the database firewall filter is used in white-list mode,
'USE <db>' should be allowed. When connecting, it is always
possible to specify the database anyway so restricting
'USE <db>' serves no purpose.
If a script variable resolves to an empty string, the replacement attempt
will fail with an out-of-memory error. The following realloc call will
fail as it requires a positive value for the new size.
The test now checks that both users with passwords and users without
passwords work through MaxScale when skip_authentication is enabled. In
addition to this, the test also makes sure that the wrong password and a
missing password are properly detected.
The result of the authentication should be ignored but the scramble that
is calculated as a side-effect still needs to be stored. This can be done
by altering the SQL used to get the matching row to only match on the
username, not the network address.
Also expanded the test case to cover the use of bad credentials.
The new parameter allows the session to be "locked" to the master server
after a stored procedure is called. This will keep the session state
consistent if the stored procedure call modifies the state of the session.
The configuration for mxs1323_retry_read now uses shorter timeouts for
monitors. This should help the monitors detect the server failures before
the result of the SELECT returns. also increased the time the query sleeps
before returning.
If both socket and network options are listed, a clear error message is
printed. The usage is also split into two lines to make it clear that the
options should be used separately.
The removal of a server from a service is intended to affect only new
sessions.
Added a test that checks that the connections are kept open even if the
server is removed from the service.
MXS-1412: while discarding a result set don't buffer any data: this
avoids to store useless data.
Additionally the colum definitions buffer is used instead of the offset
value.
By processing each buffer individually, the need to iterate over the whole
resultset is removed. Profiling showed that most of the time was spent
navigating the linked list of buffers when an offset into the whole
resultset was used instead of an offset to the individual response buffer.
Basically it would be trivial to report far more operations
explicitly, but for the fact that the values in qc_query_op_t
currently, quite unnecessarily, form a bitmask.
In 2.2 that is no longer the case, so other operations will be
added there.
