2018-06-01CURLOPT_RESOLVE: always purge old entry firstAlibek.Jorajev
If there's an existing entry using the selected name. Closes #2622
2018-03-17resolve: add CURLOPT_DNS_SHUFFLE_ADDRESSESRick Deist
This patch adds CURLOPT_DNS_SHUFFLE_ADDRESSES to explicitly request shuffling of IP addresses returned for a hostname when there is more than one. This is useful when the application knows that a round robin approach is appropriate and is willing to accept the consequences of potentially discarding some preference order returned by the system's implementation. Closes #1694
2018-03-12Revert "hostip: fix compiler warning: 'variable set but not used'"Daniel Stenberg
This reverts commit a577059f92fc65bd6b81717f0737f897a5b34248. The assignment really needs to be there or we risk working with an uninitialized pointer.
2018-03-11hostip: fix compiler warning: 'variable set but not used'Michael Kaufmann
2018-02-21url: Add option CURLOPT_RESOLVER_START_FUNCTIONFrancisco Sedano
- Add new option CURLOPT_RESOLVER_START_FUNCTION to set a callback that will be called every time before a new resolve request is started (ie before a host is resolved) with a pointer to backend-specific resolver data. Currently this is only useful for ares. - Add new option CURLOPT_RESOLVER_START_DATA to set a user pointer to pass to the resolver start callback. Closes https://github.com/curl/curl/pull/2311

2017-11-17resolve: allow IP address within [] bracketsDaniel Stenberg
... so that IPv6 addresses can be passed like they can for connect-to and how they're used in URLs. Added test 1324 to verify Reported-by: Alex Malinovich Fixes #2087 Closes #2091
2017-10-25time: rename Curl_tvnow to Curl_nowDaniel Stenberg
... since the 'tv' stood for timeval and this function does not return a timeval struct anymore. Also, cleaned up the Curl_timediff*() functions to avoid typecasts and clean up the descriptive comments. Closes #2011
2017-10-25timediff: return timediff_t from the time diff functionsDaniel Stenberg
... to cater for systems with unsigned time_t variables. - Renamed the functions to curlx_timediff and Curl_timediff_us. - Added overflow protection for both of them in either direction for both 32 bit and 64 bit time_ts - Reprefixed the curlx_time functions to use Curl_* Reported-by: Peter Piekarski Fixes #2004 Closes #2005

2016-11-18lib: fix compiler warnings after de4de4e3c7cMarcel Raad
Visual C++ now complains about implicitly casting time_t (64-bit) to long (32-bit). Fix this by changing some variables from long to time_t, or explicitly casting to long where the public interface would be affected. Closes #1131

2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines. Reported-by: David Benjamin Fixes #743

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

2015-03-14hostip: Fix signal race in Curl_resolv_timeout.Tobias Stoeckmann
A signal handler for SIGALRM is installed in Curl_resolv_timeout. It is configured to interrupt system calls and uses siglongjmp to return into the function if alarm() goes off. The signal handler is installed before curl_jmpenv is initialized. This means that an already installed alarm timer could trigger the newly installed signal handler, leading to undefined behavior when it accesses the uninitialized curl_jmpenv. Even if there is no previously installed alarm available, the code in Curl_resolv_timeout itself installs an alarm before the environment is fully set up. If the process is sent into suspend right after that, the signal handler could be called too early as in previous scenario. To fix this, the signal handler should only be installed and the alarm timer only be set after sigsetjmp has been called.
2015-03-03mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg
... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
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.
2014-01-28hostip: don't remove DNS entries that are in useRomulo A. Ceccon
hostcache_timestamp_remove() should remove old *unused* entries from the host cache, but it never checked whether the entry was actually in use. This complements commit 030a2b8cb. Bug: http://curl.haxx.se/bug/view.cgi?id=1327
2013-11-25hostip: don't prune DNS cache entries that are in useDaniel Stenberg
When adding entries to the DNS cache with CURLOPT_RESOLVE, they are marked 'inuse' forever to prevent them from ever being removed in normal operations. Still, the code that pruned out-of-date DNS entries didn't care for the 'inuse' struct field and pruned it anyway! Reported-by: Romulo A. Ceccon Bug: http://curl.haxx.se/bug/view.cgi?id=1303
2013-08-08global dns cache: fix memory leakDaniel Stenberg
The take down of the global dns cache didn't take CURLOPT_RESOLVE names into account.
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.
