bug#11763265 Potential bug with new --raw mode with mysqlbinlog
There are two reported artifacts on possible operations with uninitialazed Log_event* pointer
In fact, under --raw mode only Load-data events generated by pre 5.0.3 servers is the valid issue.
That relates to the assignment Load_log_event *le= (Load_log_event*)ev
where rhs is not initialized when --raw.
Rotate event is indeed handled correctly.
Fixed with enforcing all events incl LOAD_EVENT, CREATE_FILE_EVENT to be dumped as raw_mode
is supposed to do without instantiation of the event.
In case of CREATE_FILE_EVENT another artifact is corrected to pass such event to re-formatting
to yield an event of the latest binlog-format.
Notice, in --raw mode mysqlbinlog does not copy the data file of LOAD DATA query that is does
with just -R option, and that fact is warned.
In case not raw_mode LOAD_EVENT and CREATE_FILE_EVENT require conversion into the current load-data formats. In case of raw_mode all events including the two does not need any extra treatment.
