The example query used a INSERT instead of a SELECT which does not demonstrate
the real problem with user variable modification. Updated the example and
cleaned up the text.
The readwritesplit documentation now explains the multi-statement behavior in
more detail and provides information about situations where the default
multi-statement behavior can be disabled.
Whether all queries should be routed to the master after a multistatement
query is executed can now be controlled with the `strict_multi_stmt` option.
When the option is disabled queries executed after a multistatement query will
be routed normally.
The change fixes a crash when no filebase parameter is given for the filter.
The instance creation functions of these filters had spossible memory leaks in
case errors in the configuration occurred. In addition to these, they would be
successfully created even if unexpected parameters were given.
The tee, qlafilter, namedserverfilter and topfilter now support the same filter
options: case, ignorecase and extended. The extended filter option enables
the Extended Regular Expression syntax for the filters which is used when
matching queries.
When configured to log matching queries, the dbfwfilter will log all queries
that match a rule. The rule name, user name and the query itself are logged.
It is also possible to match all queries that do not match a rule. Only the user
name and query is logged in this mode.
The manpage was out of date and was missing a BUGS section. The `--help` output
of MaxScale wrongly stated that the default is to log to shared memory as did
the documentation.
The current implementation of the session timeout functionality is not safe to
use. Added a warning to the documentation and disabled the code. If the user
tries to use it, a warning is logged.
The documentation for readwritesplit now clearly states that only connections
from MaxScale are taken into consideration when slaves are being selected.
The limitation with readconnroute and LONGBLOB is only when data is being sent
from the client to MaxScale. The client can still query for LONGBLOB data
without any side-effects.
Changed default number of threads to 1 instead of autoconfigured value and
added a new `auto` variable which enables autoconfiguration of thread count.
The number of threads used when autoconfiguratio fails was changed from 4 to 1.
The default value of using N threads where N is the number of CPU cores was
not optimal as the possibility of rescheduling was higher the more utility
threads there were. Due to this, N-1 is deemed to be the better autoconfigured
value for thread count.
