Incoming XFR doesn't log serial
I have a regex for parsing Knot 1.6 log files, as follows:
^(\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}) info: \[\.\] .XFR, incoming, \S+ finished, serial \d+ -> (\d+), \S+ seconds, \d+ messages, (\d+) bytes$
This used to work, and I'm certain of it. However, it seems that somewhere along the way, Knot has stopped logging the serial number, because in current logs, I only see:
2015-12-14T14:04:33 info: [.] IXFR, incoming, 193.0.19.190@53: finished, 0.09 seconds, 11 messages, 701611 bytes
Notice that the new serial number of the zone hasn't been logged. This has broken my parser. Is this a regression?
