Unfortunaly i think some things where not understood properly and i will
try to reclarify them.

naming convention of the files it needs to input to log to mysql database?

Yes if in your snort.conf file you have output unified2: filename
snort.log, limit 128

Then the barnyard2 -f argument needs to be snort.log

Not at the top of the file but in the rule body of your test rule

icmp any any -> any any (msg:"blabla test rule"; sid:100000001;)
                                        |---------------RULE
BODY-------------------|

Should have been
icmp any any -> any any (msg:"blabla test rule"; sid:100000001; rev:1;)
|---------------RULE BODY-------------------|

test rule, should the rules downloaded from pulled pork not have had a
revision with it already?

running it how the guide told me to, with those options.  You're saying
that at this point, the -G -S options are not allowing barnyard2 to write
the data to mysql?
