Hello,
First time user so please bear with me.
I have some quite specific in-house code that relies on the "cache->ttd"
value. I have noticed that the function "cache_reload" in "src/cache.c"
defines the following variable:
struct crec lrec
Further down in this function it makes non-terminal records for all
locally-defined RRs. It may be more of a question but why are the
"ttd", "uid" and "ns_id" fields not initialized before the various calls
to "make_non_terminals(&lrec)". When I check the value of the
"cache->ttd" in this function it's clearly just going to be random.
cache entries which don't expire are marked by setting the F_IMMORTAL
flag in the ->flags field. If that flag is set then the value of ->ttd
is meaningless and unused. It's done this way rather than assigning a
special value to ttd because the time scale varies in different
installations and there isn't a suitable "special" time value that will
always work.
Is this just an oversight or is deliberately not set?
See above.
Cheers,
Simon.
Best regards,
John.
