2015-05-12hostcache: made all host caches use structs, not pointersDaniel Stenberg
This avoids unnecessary dynamic allocs and as this also removed the last users of *hash_alloc() and *hash_destroy(), those two functions are now removed.
2015-04-03move Curl_share_lock and ref counting into Curl_fetch_addrStefan Bühler
2015-04-03fix refreshing of obsolete dns cache entriesStefan Bühler
- cache entries must be also refreshed when they are in use - have the cache count as inuse reference too, freeing timestamp == 0 special value - use timestamp == 0 for CURLOPT_RESOLVE entries which don't get refreshed - remove CURLOPT_RESOLVE special inuse reference (timestamp == 0 will prevent refresh) - fix Curl_hostcache_clean - CURLOPT_RESOLVE entries don't have a special reference anymore, and it would also release non CURLOPT_RESOLVE references - fix locking in Curl_hostcache_clean - fix unit1305.c: hash now keeps a reference, need to set inuse = 1
2015-01-07hostip: remove 'stale' argument from Curl_fetch_addr protoDaniel Stenberg
Also, remove the log output of the resolved name is NOT in the cache in the spirit of only telling when something is actually happening.
2014-12-27code/docs: Use correct case for IPv4 and IPv6Steve Holme
For consistency, as we seem to have a bit of a mixed bag, changed all instances of ipv4 and ipv6 in comments and documentations to use the correct case.
2014-08-31resolve: cache lookup for async resolversMichael Wallner
While waiting for a host resolve, check if the host cache may have gotten the name already (by someone else), for when the same name is resolved by several simultanoues requests. The resolver thread occasionally gets stuck in getaddrinfo() when the DNS or anything else is crappy or slow, so when a host is found in the DNS cache, leave the thread alone and let itself cleanup the mess.
2013-09-17dns: fix compilation with MinGW from commit df69440d05f113Steve Holme
Avoid 'interface' literal that some MinGW versions define as a macro Additionally, corrected some very, very minor coding style errors.
2013-09-12libcurl: New options to bind DNS to local interfaces or IP addressesKim Vandry
2013-08-08global dns cache: didn't work [regression]Daniel Stenberg
CURLOPT_DNS_USE_GLOBAL_CACHE broke in commit c43127414d89ccb (been broken since the libcurl 7.29.0 release). While this option has been documented as deprecated for almost a decade and nobody even reported this bug, it should remain functional. Added test case 1512 to verify
2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2012-11-18fixed memory leak: CURLOPT_RESOLVE with multi interfaceDaniel Stenberg
DNS cache entries populated with CURLOPT_RESOLVE were not properly freed again when done using the multi interface. Test case 1502 added to verify. Bug: http://curl.haxx.se/bug/view.cgi?id=3575448 Reported by: Alex Gruz
2011-12-31CURLOPT_RESOLVE: avoid adding already present host namesDaniel Stenberg
The load host names to DNS cache function was moved to hostip.c and it now makes sure to not add host names that already are present in the cache. It would previously lead to memory leaks when for example using the --resolve and multiple URLs on the command line.
2011-12-23resolve: don't leak pre-populated dns entriesDaniel Stenberg
CURLOPT_RESOLVE populates the DNS cache with entries that are marked as eternally in use. Those entries need to be taken care of when the cache is killed off. Bug: http://curl.haxx.se/bug/view.cgi?id=3463121 Reported by: "tw84452852"

2011-04-25Fixed compilation when the synchronous resolver is usedDan Fandrich
2011-04-25async resolvers: further cleanupsDaniel Stenberg
asyn-ares.c and asyn-thread.c are two separate backends that implement the same (internal) async resolver API for libcurl to use. Backend is specified at build time. The internal resolver API is defined in asyn.h for asynch resolvers.
2011-04-25asynch resolvers: cleanupDaniel Stenberg
Fixed indents, coding conventions and white space edits. Modified the c-ares completion callback function to again NOT read the conn data when the ares handle is being taken down as then it may have been freed already.
2011-04-25asynch resolvers: unifiedVsevolod Novikov
Introducing an internal API for handling of different async resolver backends.

2011-03-23ipv6: only probe onceDaniel Stenberg
Move ipv6-functional-probe into a single function that is used from all places that need to know. Make the probe function store the result in a static variable so that subsequent invokes just returns the previous result and won't have to probe again.
2010-12-27c-ares: fix cancelled resolvesDaniel Stenberg
When built IPv6-enabled, we could do Curl_done() with one of the two resolves having returned already, so when ares_cancel() is called the resolve callback ends up doing funny things (sometimes resulting in a segfault) since it would try to actually store the previous resolve even though we're shutting down the resolve. This bug was introduced in commit 8ab137b2bc9630ce so it hasn't been included in any public release. Bug: http://curl.haxx.se/bug/view.cgi?id=3145445 Reported by: Pedro Larroy
2010-11-11ip_version: moved to connection structDaniel Stenberg
The IP version choice was previously only in the UserDefined struct within the SessionHandle, but since we sometimes alter that option during a request we need to have it on a per-connection basis. I also moved more "init conn" code into the allocate_conn() function which is designed for that purpose more or less.

2010-01-22Definitions of resolver specialty compile-time defines CURLRES_* movedYang Tse
from hostip.h to setup.h in order to allow proper inclusion in any file. This represents no functional change at all in which resolver is used, everything still works as usual, internally and externally there is no difference in behavior.
2010-01-22Constantine Sapuntzakis refactoring of async callbacks, allowingYang Tse
removal of Curl_addrinfo_copy(), Curl_addrinfo6_callback(), and Curl_addrinfo4_callback()
2009-11-11- Constantine Sapuntzakis posted bug #2891595Daniel Stenberg
(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.

2008-07-09- Andreas Schuldei improved Phil Blundell's patch for IPv6 using c-ares, and IDaniel Stenberg
edited it slightly. Now you should be able to use IPv6 addresses fine even with libcurl built to use c-ares.
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.
