Yang Tse 59939313f8 Make usage of calloc()'s arguments consistent with rest of code base 2009-11-18 10:33:54 +00:00
Yang Tse 05a4abea04 Constantine Sapuntzakis patch for hostip.c 
No need for a separate variable ndns.

The memory leak detection will detect code that fails to release a dns reference.

The DEBUGASSERT will detect code that releases too many references.

Yang Tse 668dc0ad87 Make hostip.c compile again 2009-11-12 04:32:08 +00:00
Daniel Stenberg fb5f332834 - Constantine Sapuntzakis posted bug #2891595 
(http://curl.haxx.se/bug/view.cgi?id=2891595) which identified how an entry
  in the DNS cache would linger too long if the request that added it was in
  use that long. He also provided the patch that now makes libcurl capable of
  still doing a request while the DNS hash entry may get timed out.

Daniel Stenberg 7e07da977c - Peter Sylvester made a debug featuer for Curl_resolv() that now will force 
libcurl to resolve 'localhost' whatever name you use in the URL *if* you set
  the --interface option to (exactly) "LocalHost". This will enable us to
  write tests for custom hosts names but still use a local host server.

Yang Tse 33a3753c3f libcurl's memory.h renamed to curl_memory.h 2009-04-21 11:46:16 +00:00
Yang Tse 9770899a4b Moved potential inclusion of system's malloc.h and memory.h header files to 
setup_once.h.  Inclusion of each header file is based on the definition of
NEED_MALLOC_H and NEED_MEMORY_H respectively.

Yang Tse a0ef686c54 Merged existing IPv4 and IPv6 Curl_ip2addr functions into a single one 
which now also takes a protocol address family argument.

Yang Tse 0ce97f77e0 Use our Curl_addrinfo definition even when an addrinfo struct is available. 
Use a wrapper function to call system's getaddrinfo().

Daniel Stenberg 0cd8840dba - Andreas Schuldei improved Phil Blundell's patch for IPv6 using c-ares, and I 
edited it slightly. Now you should be able to use IPv6 addresses fine even
  with libcurl built to use c-ares.

Daniel Stenberg b9d66dca51 - Dmitry Popov filed bug report #1911069 
(http://curl.haxx.se/bug/view.cgi?id=1911069) that identified a race
  condition in the name resolver code when the DNS cache is shared between
  multiple easy handles, each running in simultaneous threads that could cause
  crashes.
 2008-03-11 22:55:23 +00:00
Daniel Stenberg 991505e077 Woops, partly revert my previous commit and do it slightly differently instead. 
The signalling of that a global DNS cache is wanted is done by setting the
option but the setting of the internal variable that it is in use must not be
done until it finally actually gets used!

NOTE and WARNING: I noticed that you can't actually switch off the global dns
cache with CURLOPT_DNS_USE_GLOBAL_CACHE but you couldn't do that previously
either and the option is very clearly and loudly documented as DO NOTE USE so
I won't bother to fix this bug now.
 2008-01-15 22:44:12 +00:00
Daniel Stenberg 56f17d2c9f I made the torture test on test 530 go through. This was actually due to 
silly code left from when we switched to let the multi handle "hold" the dns
cache when using the multi interface... Of course this only triggered when a
certain function call returned error at the correct moment.

Daniel Stenberg 54967d2a3a Thomas J. Moore provided a patch that introduces Kerberos5 support in 
libcurl. This also makes the options change name to --krb (from --krb4) and
CURLOPT_KRBLEVEL (from CURLOPT_KRB4LEVEL) but the old names are still
 2007-07-01 22:01:18 +00:00
Daniel Stenberg 62f0f5571d Robert Iakobashvili re-arranged the internal hash code to work with a custom 
hash function for different hashes, and also expanded the default size for
the socket hash table used in multi handles to greatly enhance speed when
very many connections are added and the socket API is used.

Gisle Vanem e4d6ade4b3 Moved functions common to IPv4 and C-ares to hostip.c;
