The monitor permission checks didn't use the standard connection timeouts but
used hard-coded values. The config.c tried to connect to the embedded library
but since it is not used by it anymore, it always fails.
The number of written characters is now checked and should be lower than
compared bytes. The parameters to the dbusers.c query functions are now const
where possible.
Previously the users needed at least SELECT permission on the database level to
be able to connect with a default database through MaxScale. With this change,
the query that retrieves the database users has been changed to also include
table-level grants for users. This will allow users with grants to only some of
the tables in a database to be able to connect through MaxScale with a default
database.
The queries are now created at runtime to allow for a more varied syntax. This
removes the need to have separate query strings for the standard mysql.user
table and for the MySQL 5.7 version of it. In addition to this, the exclusion
of the root user is now done at the same time which removes the need to manually
form the query string.
Now, qc_mysqlembedded is linked against MySQL's embedded library,
and MaxScale itself against Connector-C.
So, in order to build MaxScale, Connector-C must be installed.
This has been tested with Connector-C 2.2.1.
The build variable MYSQLCLIENT_LIBRARIES is no longer used.
Earlier the same (or almost the same) code was duplicated in
several places.
A conflicting declaration was also removed. There was no
implementation for that declaration.
LOGIF and skygw_write_log removed from server/core/*.c and
replaced with calls to MXS_(ERROR|WARNING|NOTICE|INFO|DEBUG).
This is a mechanism change, no updating of the actual message
has been performed.
Currently this causes a very small performance hit, since the
check whether the priority is enabled or not is performed in
the function that is called and not before the function is called.
Once all LOGIFs and skygw_write_logs have been replaced, the
behaviour will be altered back to what it was.
The change to the mysql.user table in MySQL 5.7 caused MaxScale to stop
working with it. This commit adds functionality that checks which version of
the user data query should be made. It also moves common code related to
server version strings to server.c
The log manager variables lm_enabled_log_files_bitmask, log_ses_count
and tls_log_info that earlier were declared separately in every
c-file are now declared in the log_manager.h header.
