dbusers.c: Added function for setting read, write and connection timeout values. Set default timeouts for getUsers. Defaults are listed in service.c
gateway.c:shutdown_server is called whenever MaxScale is to be shut down. Added call for service_shutdown to shutdown_server.
service.c:service_alloc: replaced malloc with calloc and removed unnecessary zero/NULL initialization statements as a consequence.
serviceStart: Exit serviceStartPort loop if shutdown flag is set for the service.
serviceStartAll: Exit serviceStart loop if shutdown flag is set for the service.
service.c: Added service_shutdown which sets shutdown flag for each service found in allServices list.
service.h: Added prototype for service_shutdown
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;
log_manager.cc:
Log manager handles cases where there are mismatch in user privileges.
Mark log files enabled in the global lm_enabled_logfiles_bitmask after initialization so that it reflects reality in error cases. In general, take into account the possibility that any phase in initialization may fail and read return values.
Replaced file_exists_and_is_writable to check_file_and_path which has a slightly different logic and which detects if file open fails for a few different reasons.
Improved logging (in stderr) in general in error cases.
gateway.c: Also check home directory accessibility in case when it is provided as a command-line argument. Added function check_dir_access to provide that function. Read return value of skysql_logmanager_init and exit (nicely) if it failed.
skygw_utils.cc: initialize mlist with version number 2, which indicates that object is initialized (different than zero) and that there are no active updates on the object (version%2==0).
