2019-01-07curl_multi_remove_handle() don't block terminating c-ares requestsBrad Spencer
Added Curl_resolver_kill() for all three resolver modes, which only blocks when necessary, along with test 1592 to confirm curl_multi_remove_handle() doesn't block unless it must. Closes #3428 Fixes #3371
2018-11-23snprintf: renamed and we now only use msnprintf()Daniel Stenberg
The function does not return the same value as snprintf() normally does, so readers may be mislead into thinking the code works differently than it actually does. A different function name makes this easier to detect. Reported-by: Tomas Hoger Assisted-by: Daniel Gustafsson Fixes #3296 Closes #3297
2018-11-20ares: remove fd from multi fd set when ares is about to close the fdRomain Fliedel
When using c-ares for asyn dns, the dns socket fd was silently closed by c-ares without curl being aware. curl would then 'realize' the fd has been removed at next call of Curl_resolver_getsock, and only then notify the CURLMOPT_SOCKETFUNCTION to remove fd from its poll set with CURL_POLL_REMOVE. At this point the fd is already closed. By using ares socket state callback (ARES_OPT_SOCK_STATE_CB), this patch allows curl to be notified that the fd is not longer needed for neither for write nor read. At this point by calling Curl_multi_closed we are able to notify multi with CURL_POLL_REMOVE before the fd is actually closed by ares. In asyn-ares.c Curl_resolver_duphandle we can't use ares_dup anymore since it does not allow passing a different sock_state_cb_data Closes #3238
2018-08-09asyn-thread: Remove unused macroRikard Falkeborn
The macro seems to never have been used. Closes #2852
2018-06-27easy_perform: use *multi_timeout() to get wait timesDaniel Stenberg
... and trim the threaded Curl_resolver_getsock() to return zero millisecond wait times during the first three milliseconds so that localhost or names in the OS resolver cache gets detected and used faster. Closes #2685
2018-06-16multi: fix memory leak when stopped during name resolveDaniel Stenberg
When the application just started the transfer and then stops it while the name resolve in the background thread hasn't completed, we need to wait for the resolve to complete and then cleanup data accordingly. Enabled test 1553 again and added test 1590 to also check when the host name resolves successfully. Detected by OSS-fuzz. Closes #1968
2018-03-24threaded resolver: track resolver time and set suitable timeout valuesDaniel Stenberg
In order to make curl_multi_timeout() return suitable "sleep" times even when there's no socket to wait for while the name is being resolved in a helper thread. It will increases the timeouts as time passes. Closes #2419
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
2017-08-29asyn-thread: Fixed cleanup after OOMDan Fandrich
destroy_async_data() assumes that if the flag "done" is not set yet, the thread itself will clean up once the request is complete. But if an error (generally OOM) occurs before the thread even has a chance to start, it will never get a chance to clean up and memory will be leaked. By clearing "done" only just before starting the thread, the correct cleanup sequence will happen in all cases.

2017-08-28asyn-thread: Set errno to the proper value ENOMEM in OOM situationDan Fandrich
This used to be set in some configurations to EAI_MEMORY which is not a valid value for errno and caused Curl_strerror to fail an assertion.
2017-07-10curl_setup_once: Remove ERRNO/SET_ERRNO macrosJay Satiro
Prior to this change (SET_)ERRNO mapped to GetLastError/SetLastError for Win32 and regular errno otherwise. I reviewed the code and found no justifiable reason for conflating errno on WIN32 with GetLastError/SetLastError. All Win32 CRTs support errno, and any Win32 multithreaded CRT supports thread-local errno. Fixes https://github.com/curl/curl/issues/895 Closes https://github.com/curl/curl/pull/1589

2017-05-10multi: use a fixed array of timers instead of mallocDaniel Stenberg
... since the total amount is low this is faster, easier and reduces memory overhead. Also, Curl_expire_done() can now mark an expire timeout as done so that it never times out. Closes #1472

2016-06-07resolve: enable protocol family logic for synthesized IPv6Luo Jinghua
- Enable protocol family logic for IPv6 resolves even when support for synthesized addresses is enabled. This is a follow up to the parent commit that added support for synthesized IPv6 addresses from IPv4 on iOS/OS X. The protocol family logic needed for IPv6 was inadvertently excluded if support for synthesized addresses was enabled. Bug: https://github.com/curl/curl/issues/863 Ref: https://github.com/curl/curl/pull/866 Ref: https://github.com/curl/curl/pull/867
2016-06-07resolve: add support for IPv6 DNS64/NAT64 Networks on OS X + iOSLuo Jinghua
Use getaddrinfo() to resolve the IPv4 address literal on iOS/Mac OS X. If the current network interface doesn’t support IPv4, but supports IPv6, NAT64, and DNS64. Closes #866 Fixes #863
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

2015-03-16free: instead of Curl_safefree()Daniel Stenberg
Since we just started make use of free(NULL) in order to simplify code, this change takes it a step further and: - converts lots of Curl_safefree() calls to good old free() - makes Curl_safefree() not check the pointer before free() The (new) rule of thumb is: if you really want a function call that frees a pointer and then assigns it to NULL, then use Curl_safefree(). But we will prefer just using free() from now on.
2015-03-16Bug #149: Deletion of unnecessary checks before calls of the function "free"Markus Elfring
The function "free" is documented in the way that no action shall occur for a passed null pointer. It is therefore not needed that a function caller repeats a corresponding check. http://stackoverflow.com/questions/18775608/free-a-null-pointer-anyway-or-check-first This issue was fixed by using the software Coccinelle 1.0.0-rc24.

2014-12-27code/docs: Use correct case for IPv4 and IPv6Steve Holme

2014-09-23threaded-resolver: revert Curl_expire_latest() switchDaniel Stenberg
The switch to using Curl_expire_latest() in commit cacdc27f52b was a mistake and was against the advice even mentioned in that commit. The comparison in asyn-thread.c:Curl_resolver_is_resolved() makes Curl_expire() the suitable function to use. Bug: http://curl.haxx.se/bug/view.cgi?id=1426 Reported-By: graysky
2014-08-31low-speed-limit: avoid timeout floodDaniel Stenberg
Introducing Curl_expire_latest(). To be used when we the code flow only wants to get called at a later time that is "no later than X" so that something can be checked (and another timeout be added). The low-speed logic for example could easily be made to set very many expire timeouts if it would be called faster or sooner than what it had set its own timer and this goes for a few other timers too that aren't explictiy checked for timer expiration in the code. If there's no condition the code that says if(time-passed >= TIME), then Curl_expire_latest() is preferred to Curl_expire(). If there exists such a condition, it is on the other hand important that Curl_expire() is used and not the other. Bug: http://curl.haxx.se/mail/lib-2014-06/0235.html Reported-by: Florian Weimer
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.
2014-05-22bits.close: Fixed compilation warningSteve Holme
warning: implicit declaration of function 'connclose'
2014-05-22bits.close: introduce connection close trackingDaniel Stenberg
Make all code use connclose() and connkeep() when changing the "close state" for a connection. These two macros take a string argument with an explanation, and debug builds of curl will include that in the debug output. Helps tracking connection re-use/close issues.
2014-01-10threaded-resolver: never use NULL hints with getaddrinfoDaniel Stenberg
The net effect of this bug as it appeared to users, would be that libcurl would timeout in the connect phase. When disabling IPv6 use but still using getaddrinfo, libcurl would wrongly not init the "hints" struct field in init_thread_sync() which would subsequently lead to a getaddrinfo() invoke with a zeroed hints with ai_socktype set to 0 instead of SOCK_STREAM. This would lead to different behaviors on different platforms but basically incorrect output. This code was introduced in 483ff1ca75cbea, released in curl 7.20.0. This bug became a problem now due to the happy eyeballs code and how libcurl now traverses the getaddrinfo() results differently.

2013-09-10NI_MAXSERV: remove all use of itDaniel Stenberg
Solaris with the SunStudio Compiler is reportedly missing this define, but as we're using it without any good reason on all the places it was used I've now instead switched to just use sensible buffer sizes that fit a 32 bit decimal number. Which also happens to be smaller than the common NI_MAXSERV value which is 32 on most machines. Bug: http://curl.haxx.se/bug/view.cgi?id=1277 Reported-by: D.Flinkmann
2013-02-18resolver_error: remove wrong error message outputDaniel Stenberg
The attempt to use gai_strerror() or alternative function didn't work as the 'sock_error' field didn't contain the proper error code. But since this hasn't been reported and thus isn't really a big deal I decided to just scrap the whole attempt to output the detailed resolver error and instead remain with just stating that the resolving of the name failed.

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.

2012-01-04win32-threaded-resolver: stop using a dummy socketDaniel Stenberg
Previously the code would create a dummy socket while resolving just to have curl_multi_fdset() return something but the non-win32 version doesn't do it this way and the creation and use of a socket that isn't made with the common create-socket callback can be confusing to apps using the multi_socket API etc. This change removes the dummy socket and thus will cause curl_multi_fdset() to return with maxfd == -1 more often.
