KILL commands are now sent to the backends in an asynchronous manner. As
the LocalClient class is used to connect to the servers, this will cause
an extra connection to be created on top of the original connections
created by the session.
If the user does not have the permissions to execute the KILL, the error
message is currently lost. This could be solved by adding a "result
handler" into the LocalClient class which is called with the result.
If the client sends data before authentication is complete, it must not be
discarded and it needs to be processed like as if it was sent in a
separate network packet.
The enums exposed by the connector are not intended to be used by the
users of the library. The fact that the protocol, and other, modules used
it was in violation of how the library is intended to be used.
Adding an internal mapping into MaxScale also removes some of the
dependencies that the core has on the connector.
Cleaned up the MaxScale version of the mysql.h header by removing all
unused includes. This revealed a large amount of dependencies on these
removed includes in other files which needed to be fixed.
Also sorted all includes in changed files by type and alphabetical
order. Removed explicit revision history from modified files.
When a LOAD DATA LOCAL INFILE is done, the last packet is an empty packet
which does not contain the command byte. Some parts of the MySQL protocol
modules expected that a command is always present. The proper way to
handle this is to use the mxs_mysql_get_command function which does bounds
checking.
The initial setting of sql_mode affects how MaxScale initially
behaves with respect to autocommit.
When 'set sql_mode=[default|oracle];" is encountered, the query
classifier and autocommit modes are adjusted accordingly.
A custom parser for detecting "set sql_mode=ORACLE" is needed
and writing that is C++ is more convenient than writing it in
C. Consequently, so as to be able to use that parser, mysql_client
must be compiled as C++.
