nscd won't cache anything if I run this code: struct addrinfo hint = {0}; hint.ai_family = PF_INET; getaddrinfo(argv[1], NULL, &hint, &result);

But it works fine if I remove "hint.ai_family = PF_INET". KDE always sets ai_family, though.

I did some tests using the little program I found here: http://www.logix.cz/michal/devel/various/getaddrinfo.c.xp hints.ai_family = PF_UNSPEC; -> no nscd caching hints.ai_family = PF_INET; -> nscd caching works hints.ai_family = PF_INET6; -> nscd caching works hope this helps... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

INET and INET6 are cached, UNSPEC isn't... So it's not new (maybe even intended?) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From the nscd changelog:

* Thu Nov 07 2002 - kukuk@suse.de - getaddrinfo(): get host information for AF_INET and AF_INET6 only from the same service [Bug #21237] Old bug which I cannot acces... (tried bugzilla.suse.de) -- And for the negative cache = 0: * Tue Apr 19 2005 - mls@suse.de [...] - nscd: support a negative timeout of zero, used by hosts cache -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

However, it would be interesting to know if it's a feature or a bug why nscd doesn't cache those queries itself.

Mhh, strange. getaddrinfo now caches the getaddrinfo calls even with pf_unspec. But some konqueror4 dns queries won't be served from cache by nscd. Maybe those massive parallel dns requests confuse the resolver... don't know. However, the bug seems to be solved upstream (dns cache patch is already committed), so IMHO you may close this report as fixed. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
