2008-03-11- Dmitry Popov filed bug report #1911069Daniel Stenberg
(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.
2008-01-15Woops, partly revert my previous commit and do it slightly differently instead.Daniel Stenberg
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.
2008-01-15I made the torture test on test 530 go through. This was actually due toDaniel Stenberg
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.

2007-07-01Thomas J. Moore provided a patch that introduces Kerberos5 support inDaniel Stenberg
libcurl. This also makes the options change name to --krb (from --krb4) and CURLOPT_KRBLEVEL (from CURLOPT_KRB4LEVEL) but the old names are still
2007-06-26Robert Iakobashvili re-arranged the internal hash code to work with a customDaniel Stenberg
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.

2006-07-07Ingmar Runge provided a source snippet that caused a crash. The reason forDaniel Stenberg
the crash was that libcurl internally was a bit confused about who owned the DNS cache at all times so if you created an easy handle that uses a shared DNS cache and added that to a multi handle it would crash. Now we keep more careful internal track of exactly what kind of DNS cache each easy handle uses: None, Private (allocated for and used only by this single handle), Shared (points to a cache held by a shared object), Global (points to the global cache) or Multi (points to the cache within the multi handle that is automatically shared between all easy handles that are added with private caches).
2006-05-04Roland Blom filed bug report #1481217Daniel Stenberg
(http://curl.haxx.se/bug/view.cgi?id=1481217), with follow-ups by Michele Bini and David Byron. libcurl previously wrongly used GetLastError() on windows to get error details after socket-related function calls, when it really should use WSAGetLastError() instead. When changing to this, the former function Curl_ourerrno() is now instead called Curl_sockerrno() as it is necessary to only use it to get errno from socket-related functions as otherwise it won't work as intended on Windows.

(more logical).
2006-02-16Shmulik Regev provided a fix for the DNS cache when using short life times,Daniel Stenberg
as previously it could be holding on to old cached entries longer than requested.

2004-06-24Replaced all uses of sprintf() with the safer snprintf(). It is just aDaniel Stenberg
precaution to prevent mistakes to lead to buffer overflows.

2004-06-24Source cleanups. The major one being that we now _always_ use a Curl_addrinfoDaniel Stenberg
linked list for name resolved data, even on hosts/systems with only IPv4 stacks as this simplifies a lot of code.
