Gisle Vanem's IPv6-on-Windows patch applied!

022996e5c7
Dirk Manske made the share-locking around DNS lookups a bit "looser" so that
...
multiple DNS lookups can run simultaneously faster. The downside is that
resolving the same host name now can be made at once from multiple threads,
but the upside is that threads now don't alwys have to wait for the others'
resolves. Test case 506 updated accordingly.

343291ce37
Based on a patch provided by Siddhartha Prakash Jain. In Curl_resolv() when
...
my_getaddrinfo() has been called (and wait has been set to TRUE), we check
if the name already is resolved and if so don't return wait status to the
parent. This can happen with IP-only names.

Jeff Pohlmeyer did some marvelous debugging to track this one down. We MUST
...
NOT free the existing hash entry when we try to add a new one that matches
an existing entry. We now instead free the new one, and make the parent
function use the old entry's struct instead.

EAGAIN on older (correct) glibc versions indicate a problem and not the need
...
for a bigger buffer and this is indeed badness for us. Making this work
on both old and new glibc versions require an ugly loop that in its worse
form cause 45 bad loops when using the correct glibc and a non-resolving
host name... :-/
We want a better fix. Badly.

2002-11-11 22:51:09 +00:00

Curl_resolv() now returns a different struct, and it contains a reference
...
counter so that the caller needs to decrease that counter when done with
the returned data.
If compiled with MALLOCDEBUG I've added some extra checking that the counter
is decreased before a handle is closed etc.

Cris Bailiff found this flaw, gethostbyname_r() on linux returns 0 even

when it can't lookup the name (at least in some cases) and thus we need

Now uses sigsetjmp() and siglongjmp() to bail out from slow name lookups in

case a timeout is set. This seems to work. God knows if it is good enough
or what kind of side-effects we introduce here and now.
I'll close my eyes and cross my fingers. Hard.

In order to not get problems with DNS cache pruning, we no longer store
...
any name resolved data in any curl handle struct. That way, we won't mind
if the cache entries are pruned for the next time we need them. We'll just
resolve them again instead.
This changes the Curl_resolv() proto. It modifies the SessionHandle struct
but perhaps most importantly, it'll make the internals somewhat dependent
on the DNS cache not being disabled as that will cripple operations somewhat.
Especially for persistant connections.

Now first check if IPv6 is supported, then use PF_UNSPEC. If not, use PF_INET.

IPv6 hosts.
