Not sure this adds much more coverage then there was, but minimally
more recent software versions.
The instances/passwords were ephemeral, so hostname and password hashes
etc aren't useful to anyone.
We were parsing MySQL using bigendian even though the protocol is
specified as with "least significant byte first" [1]. This is most
problematic when parsing length encoded strings with 2 byte length
fields...
Further, I think, the EOF_Packet parsing was borked, either due to
testing the CLIENT_DEPRECATE_EOF with the wrong endianness, or due to
the workaround in Resultset processing raising mysql_ok(). Introduce a
new mysql_eof() that triggers for EOF_Packet's and remove the fake
mysql_ok() Resultset invocation to fix. Adapt the mysql script and tests
to account for the new event.
This is a quite backwards incompatible change on the event level, but
due to being quite buggy in general, doubt this matters to many.
I think there is more buried, but this fixes the violation of the simple
"SHOW ENGINE INNODB STATUS" and the existing tests continue to
succeed...
