Error messages inside the code
There are error messages which are composed in the code directly, particularly (but probably not only) in replication. At the very least they can appear in error logs or stderr, but possibly they can also be added to SQL errors with generic patterns, like errors passed through from an engine.
Examples:
client/mysql_upgrade.c: print_error("Version check failed. Got the following error when calling "
|
client/mysql_upgrade.c- "the 'mysql' command line client", &ds_version);
|
sql/slave.cc: errmsg= "The slave I/O thread stops because master and slave have equal \
|
sql/slave.cc-MySQL server ids; these ids must be different for replication to work (or \
|
sql/slave.cc- rli->report(ERROR_LEVEL, ER_SLAVE_RELAY_LOG_READ_FAILURE, NULL,
|
sql/slave.cc- ER_THD(thd, ER_SLAVE_RELAY_LOG_READ_FAILURE), "\
|
sql/slave.cc-Could not parse relay log event entry. The possible reasons are: the master's \
|
sql/slave.cc-binary log is corrupted (you can check this by running 'mysqlbinlog' on the \
|
sql/slave.cc-binary log), the slave's relay log is corrupted (you can check this by running \
|
sql/slave.cc:'mysqlbinlog' on the relay log), a network problem, or a bug in the master's \
|
sql/slave.cc-or slave's MySQL code. If you want to check the master's binary log or slave's \
|
sql/slave.cc-relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' \
|
and then the corresponding test results will have to be updated, e.g.
./suite/rpl/r/rpl_server_id1.result:Last_IO_Error = 'Fatal error: The slave I/O thread stops because master and slave have equal MySQL server ids; these ids must be different for replication to work (or the -
