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.
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.
This will prevent the routing of queries that modify data to the slaves.
In the future a more intricate solution can done where all the statements
are parsed and the destination is resolved based on the actual contents.
The caller DCB was used instead of the session client DCB. This caused
a crash when a backend DCB was getting the shared data since those DCBs
have a NULL data pointer.
The write queue spinlock was released in dcb_write_tidy_up without first
acquiring it. This caused a crash when two threads try to interact with
the write queue at the same time.
The old message logged the function name and thread ID which are not useful
to the end user. The thread ID should only be printed for debugging purposes,
not general error messages.
Both the passwords and temporary files of the embedded library were stored
in the same directory. Now the directories are separated and the embedded
library uses the temporary directory. The datadir cleanup also now only
cleans up the temporary data directory.
The schemarouter checks if the service has this parameter and if it
is not there, it is automatically enabled. The parameter was not
added as a qualified service parameter so the router couldn't see
the parameter as defined even if it was.
The older versions of Bison use the deprecated versions of various options.
The automatic prefixing of tokens is not present in older versions so to
accommodate for this, all tokens were manually prefixed.
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.

The lack of user definition lines in the dbfwfilter rule file was ignored
previously but this change makes the lack of users an error again. Also
added function documentation to some of the functions.
The monitor timeouts can now be larger than the monitor interval. This will
allow the combination of low monitoring intervals and large network timeouts.
If a network experiences some periodic lag, it is desirable to allow large
timeout values.
The real username and host is now logged in addition to the user definition
that it matched. The messages also have the service name to distinct
connections to two different services which both use the same filter.
