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
Maxinfo now supports the shutdown command which shuts down a service, monitor
or MaxScale itself and the restart command which restarts a stopped monitor
or service.
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.
server.c: Added new member to SERVER->master_err_is_logged. It is used if server loses master status. It causes error log print in readwritesplit router's eror handling. Initial value is false and it is set always to false when server's status is set to master.
Added message log printing to mysql monitor, if master status changes to something else. It is not warning or error but only information which probably interests the user.
readwritesplit.c:Muted warnings and error printings in cases if slaves are not found if it is allowed to have a master only.
readwritesplit.c:Corrected error log printing in case where master lost its status. REdundant prints are removed.
void session_enable_log(SESSION* ses, logfile_id_t id)
and
void session_disable_log(SESSION* ses, logfile_id_t id)
Which switch specific log type on/off if the log type in question is not generally enabled.
Each thread carries a thread-specific struct log_info_t which includes members for current session id and bitfield for enabled log types for the current session. That information is checked before actual log write functions are called.
Each file where session-specific logging is used, must include the following exports:
/** Defined in log_manager.cc */
extern int lm_enabled_logfiles_bitmask;
extern size_t log_ses_count[];
extern __thread log_info_t tls_log_info;
