* hostip: on macOS avoid DoH when given a numerical IP addressDaniel Stenberg2020-05-261-6/+16
| | | | | | | | | When USE_RESOLVE_ON_IPS is set (defined on macOS), it means that numerical IP addresses still need to get "resolved" - but not with DoH. Reported-by: Viktor Szakats Fixes #5454 Closes #5459
* hostip: make Curl_printable_address not return anythingDaniel Stenberg2020-05-191-23/+20
| | | | | | | | | It was not used much anyway and instead we let it store a blank buffer in case of failure. Reported-by: MonocleAI Fixes #5411 Closes #5418
* source cleanup: remove all custom typedef structsDaniel Stenberg2020-05-151-11/+11
| | | | | | | | | | | - Stick to a single unified way to use structs - Make checksrc complain on 'typedef struct {' - Allow them in tests, public headers and examples - Let MD4_CTX, MD5_CTX, and SHA256_CTX typedefs remain as they actually typedef different types/structs depending on build conditions. Closes #5338
* conncache: various concept cleanupsDaniel Stenberg2020-04-301-5/+7
| | | | | | | | | | | | | | | | More connection cache accesses are protected by locks. CONNCACHE_* is a beter prefix for the connection cache lock macros. Curl_attach_connnection: now called as soon as there's a connection struct available and before the connection is added to the connection cache. Curl_disconnect: now assumes that the connection is already removed from the connection cache. Ref: #4915 Closes #5009
* socks: make the connect phase non-blockingDaniel Stenberg2020-02-171-12/+12
| | | | | | Removes two entries from KNOWN_BUGS. Closes #4907
* fix: Copyright year out of date, should be 2020Daniel Stenberg2020-01-101-1/+1

* hostip: move code to resolve IP address literals to `Curl_resolv`Marcel Raad2020-01-101-17/+39
| | | | | | | | | | | | | | | | The code was duplicated in the various resolver backends. Also, it was called after the call to `Curl_ipvalid`, which matters in case of `CURLRES_IPV4` when called from `connect.c:bindlocal`. This caused test 1048 to fail on classic MinGW. The code ignores `conn->ip_version` as done previously in the individual resolver backends. Move the call to the `resolver_start` callback up to appease test 655, which wants it to be called also for literal addresses. Closes https://github.com/curl/curl/pull/4798
* hostip: suppress compiler warningMarcel Raad2019-12-131-0/+4
| | | | | | | With `--disable-doh --disable-threaded-resolver`, the `dns` parameter is not used. Closes https://github.com/curl/curl/pull/4692
* lib: silence conversion warningsMarcel Raad2019-10-011-1/+1
| | | | Closes https://github.com/curl/curl/pull/4444
* timediff: make it 64 bit (if possible) even with 32 bit time_tDaniel Stenberg2019-08-011-1/+1
| | | | | | | ... to make it hold microseconds too. Fixes #4165 Closes #4168
* cleanup: remove the 'numsocks' argument used in many placesDaniel Stenberg2019-07-301-4/+2
| | | | | | | | | It was used (intended) to pass in the size of the 'socks' array that is also passed to these functions, but was rarely actually checked/used and the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries that should be used instead. Closes #4169
* hostip: CURL_DISABLE_SHUFFLE_DNSDaniel Stenberg2019-05-171-1/+4

* doh: disable DOH for the cases it doesn't workDaniel Stenberg2019-05-111-3/+4
| | | | | | | | | | Due to limitations in Curl_resolver_wait_resolv(), it doesn't work for DOH resolves. This fix disables DOH for those. Limitation added to KNOWN_BUGS. Fixes #3850 Closes #3857
* CURLOPT_DNS_USE_GLOBAL_CACHE: removeDaniel Stenberg2019-04-111-34/+0
| | | | | | | | Remove the code too. The functionality has been disabled in code since 7.62.0. Setting this option will from now on simply be ignored and have no function. Closes #3654

* hostip: support wildcard hostsClaes Jakobsson2018-12-271-0/+30
| | | | | | | | | | | | | | | | | This adds support for wildcard hosts in CURLOPT_RESOLVE. These are try-last so any non-wildcard entry is resolved first. If specified, any host not matched by another CURLOPT_RESOLVE config will use this as fallback. Example send a.com to 10.0.0.1 and everything else to 10.0.0.2: curl --resolve *:443:10.0.0.2 --resolve a.com:443:10.0.0.1 \ https://a.com https://b.com This is probably quite similar to using: --connect-to a.com:443:10.0.0.1:443 --connect-to :443:10.0.0.2:443 Closes #3406 Reviewed-by: Daniel Stenberg <daniel@haxx.se>

| | | | | | | | | | | - replace tabs with spaces where possible - remove line ending spaces - remove double/triple newlines at EOF - fix a non-UTF-8 character - cleanup a few indentations/line continuations in manual examples Closes https://github.com/curl/curl/pull/3037

* CURLOPT_RESOLVE: always purge old entry firstAlibek.Jorajev2018-06-011-15/+19
| | | | | | If there's an existing entry using the selected name. Closes #2622
* resolve: add CURLOPT_DNS_SHUFFLE_ADDRESSESRick Deist2018-03-171-1/+73
| | | | | | | | | | | 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
* Revert "hostip: fix compiler warning: 'variable set but not used'"Daniel Stenberg2018-03-121-1/+1
| | | | | | | This reverts commit a577059f92fc65bd6b81717f0737f897a5b34248. The assignment really needs to be there or we risk working with an uninitialized pointer.

* url: Add option CURLOPT_RESOLVER_START_FUNCTIONFrancisco Sedano2018-02-211-0/+12
| | | | | | | | | | | | - 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

* CURLOPT_RESOLVE: Add support for multiple IP addresses per entryAnders Bakken2018-02-201-27/+89
| | | | | | | This enables users to preresolve but still take advantage of happy eyeballs and trying multiple addresses if some are not connecting. Ref: https://github.com/curl/curl/pull/2260

* time: rename Curl_tvnow to Curl_nowDaniel Stenberg2017-10-251-1/+1
| | | | | | | | | | ... 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

| | | | | | | | | | | | | | | ... 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

| | | | | | | | | 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

* lib: include curl_printf.h as one of the last headersDaniel Stenberg2016-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | 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.
