02a0f2f083 when we find a CNAME/DNAME, set the result code to DNS_R_ALIAS, so it will 
be caught properly in createfind()

16508d9185 Lower cache minimum time to 10 seconds. Enforce the minimum. 
Preliminary support for the "target" attribute of the adbname, to be used
for CNAME/DNAME chains later on.
The resolver will now do appropriate findzonecut calls, so the ADB need
not concern itself with them any more.
Fix some bugs in NXDOMAIN/NXRRSET handling.

daf83a2937 Use dns_view_simplefind(). 
Handle the NXDOMAIN and NXRRSET cases, so we don't start fetches for
data we're authoritative for.

d947011dc3 change macro name from ADB_NCACHE_MINIMUM to ADB_CACHE_MINIMUM since it's used 
as a general purpose minimum ttl, and actually set the TTL to the minimum
when re get a negative cache entry.

f6f4ceece4 more fully implement the 'standard' in6_addr, and use the macros correctly 
in adb.c

6a0f1e6b61 Make a (perhaps) temporary change to make this build on non-ipv6 aware 
OSs.  It may remain (but not in the present form) since storing ipv6
addresses in the adb makes little sense if you can't use them...
 1999-12-02 04:20:00 +00:00
Michael Graff
3115cd89bc Ignore ipv6 mapped ipv4 addresses. 
Set a default TTL for type 3 negative cache elements.  This is local to
the ADB, and cannot leak to clients, so no specs are violated.

Change a logging level to be less verbose.

294802790e Fix a lot of negative caching issues. I believe the code will use 
ncache responses from fetches and database lookups correctly now, but
there needs to be a little more cleanup here and there.  Bugs exist.

42fe494186 Minor API change. The 'factor' now ranges from 0..10. See adb.h for details. 1999-11-19 00:30:13 +00:00

70b065bd92 bits was being ORed with the mask instead of ANDed. 
Update the entry's flags too.

6dde125c2f be more cautious when updating expire times, and unify name/address buckets 1999-11-05 02:05:06 +00:00
Michael Graff
ef5e39139c remove checks for null view, since we won't let that happen. Add a bit 
of code to avoid pounding on servers that we can't find the addresses
of.  Right now the adb just stops checking for 5 minutes.

65f6d2e1c1 clean up macros to avoid HAVE_* names. First a6 is a fetch, not name, attribute. 1999-11-04 08:48:47 +00:00

93d3a6fd20 Don't say we're actually expiring addresses unless we really do. 1999-11-04 08:35:45 +00:00

11e89b9b44 update the right ttl in a/aaaa db lookups. Print ttl in seconds from now, rather than absolute time. 1999-11-04 08:29:06 +00:00

517274e709 kill name->query_pending, since that bitmask is really represented more 
accurately by other means.  Reverse the sense of fetch checking from
NO_FETCH_A() and NO_FETCH_AAAA(), etc to NAME_FETCH_A(), NAME_FETCH_AAAA(),
and add address family checks like NO_FETCH_V4() and _V6().

Fix a database dump bug where the A fetches were printed twice rather than
printing the AAAA fetches.  Add printing of A6 fetches.

3edb3c8e7d minor formatting nits, and require at least one address family 
be requested in calls to dns_adb_createfind().
