Comparing branches

1. https://github.com/ensdomains/dnssec-oracle/tree/delete-rrset ( currently under PR)
2. https://github.com/ensdomains/dnssec-oracle/tree/delete-rrset-2 (rewrite)
3. https://github.com/ensdomains/dnssec-oracle/tree/delete-rrset-3 (this version does not copy tails)

NOTES: I commented out the following tests from all the three branches as it is currently failing on #1.

Assert.equal(a_b_c.compareNames(d)      <  0, true, "one name has a difference of >1 label to the other");

Myth output log questions.

• Target contract
• Log Output

Questions

1. At Log L20, Why _function_0x05f203d9 is not converting function name from hex to ascii? (from the line number, I am guessing it was revoke() function).
2. At Log L51 is emitting the entire code (and function name is hex) so I cannot identify where the exact problem is.
3. At Log l235, the report says that function clear() has potential interger overflow at [contract code l58]( https://github.com/makoto/blockparty/blob/master/contracts/Conference.sol#L15
