f35c28214e use size_t to keep strlen() results 2004-02-23 08:38:49 +00:00

35fd1365ae simplied how create_hostcache_id() is used, and also its function somewhat 
cleared up some ssize_t/size_t mixups

7d844c430c Gisle Vanem brings name resolving timeout possibilities to windows people. 
This works by magicly starting up a new thread that can be killed when the
timeout is reached. testtesttest!

62a12b7faf No longer uses the 'ret' variable in the plain ipv4-version of 
my_getaddrinfo() (caused a warning by the IRIX MIPSPro compiler). Also
clarified the situation for the 3-arg version of gethostbyname_r() with a huge
comment.

e2b6a45cfa Make sure dns cache timeout -1 really means forever, as it is documented to 
be. Simply skip the pruning.

ccdaa0b51f Make the 'areschannel' get created in the curl_easy_init() and re-use that 
same channel during the whole curl handle's life until curl_easy_cleanup().

a7e04cac78 Mark the dns entry 'inuse' properly even when used from the cache. This 
seems to correct some host cache screw-ups I could reproduce.

4674f3f115 Make hostcache_fixoffset() take a long for offset, to fully work with 64bit 
archs, also no longer typecast pointers to ints as that is a nono on 64bit
systems.

791e49134b hide the pack_hostent proto if ipv6 is enabled, as figured out by Tor Arntsen 2004-02-05 08:34:31 +00:00

886391d145 adjusted to the modified ares_strerror() function 
NOTE that this breaks ares-compatibility, we have now officially taken the
turn into the c-ares path. We will now officially depend on c-ares for asynch
name resolves.

e1d541086c Dirk Manske fixed the ares usage even more. We could get a timeout from ares 
as well, and when failing and not getting a timeout we now include the
error message ares can provide us with.

12fa877f00 Timeout slow ares name lookups. This is based on the patch brought by 
Dirk Manske, but modified by me.

3788f25eac added a library-wide interface for doing dns cache pruning, and no longer 
make the pruning at each name lookup, only in Curl_done().

cfe53768dd if Curl_hash_add() returns NULL, we shall not free the addrinfo field as that 
is made in the hash function in the case of failure (using the already setup
'dtor' function).

a0a5668dbd do ares_destroy() on the ares handle when we're done in Curl_is_resolved() 2003-11-15 10:29:43 +00:00

a701f3dddf Siddhartha Prakash Jain found a case with a bad resolve that we didn't 
properly bail out from, when using ares.

749f5387c1 Gisle Vanem's IPv6-on-Windows patch applied! 2003-10-14 12:00:45 +00:00
Daniel Stenberg
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.

a0118fb390 just re-indented some code 2003-10-05 15:03:21 +00:00
Daniel Stenberg
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.

2297eca103 Added CURLOPT_IPRESOLVE support 2003-09-19 15:16:47 +00:00

14597475b1 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.

c1f31180a2 Curl_is_resolved(): FD_ZERO the file descriptors before we call ares_fds(). 
Problem tracked down by Bjorn Reese.

62b65a5f20 make it build without ares support 
make sure it set async false even when using ipv6 (made test case 20 fail
before)

b73612392d ares awareness/usage/support added. If configure --enable-ares is used, we 
build libcurl to use ares for asynch name resolves.

e879e26a5b 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.

7df5677b46 fixed Curl_freeaddrinfo() to only free addrinfo, and added Curl_freednsinfo() 
for freeing single dns cache entries

ca6e770837 The test for DNS cache entries left locked is now only built if 
AGGRESIVE_TEST is also defined, as an addition to MALLOCDEBUG. It doesn't
work for multi interface usage and should only be used with careful
consideration.
 2002-11-11 22:51:09 +00:00

2cff251863 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.
