    libknot/packet: compression algorithm improved · ab3b6e9a
    Mark Karpilovskij authored
    The previous compression algorithm does not compress everything it can
    in cases where there are domain names in the data section of a RR, e.g.
    when the answer contains
    
    bar.example.com  CNAME  foo.example.com
    foo.example.com  A      192.0.0.2
    
    and foo.example.com was not encountered previously, then the second RR
    leaves the 'foo' part uncompressed.
    
    The improvement resolves some of these cases by comparing the owner of a new RRset to be written
    with the last written dname instead of QNAME. Also, the effectivity was slightly increased
    according to benchmarks.
