* time: fix type conversions and compiler warningsMichael Kaufmann2017-05-241-3/+4
| | | | | | | | | Fix bugs and compiler warnings on systems with 32-bit long and 64-bit time_t. Reviewed-by: Daniel Stenberg Closes #1499
* lib: remove unused codeMarcel Raad2017-04-261-1/+0
| | | | | | | | This fixes the following clang warnings: macro is not used [-Wunused-macros] will never be executed [-Wunreachable-code] Closes https://github.com/curl/curl/pull/1448
* spelling fixesklemens2017-03-261-3/+3
| | | | Closes #1356
* checksrc: stricter no-space-before-paren enforcementDaniel Stenberg2016-12-131-1/+1
| | | | In order to make the code style more uniform everywhere
* lib: fix compiler warnings after de4de4e3c7cMarcel Raad2016-11-181-1/+1
| | | | | | | | | 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
* resolve: add error message when resolving using SIGALRMAndreas Streichardt2016-10-101-2/+5
| | | | Closes #1066
* internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg2016-06-221-9/+9

* 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. Reported-by: David Benjamin Fixes #743

* hostip: fix unintended destruction of hash tableAnthony Avina2015-05-181-1/+1
| | | | .. and added unit1602 for hash.c
* hostcache: made all host caches use structs, not pointersDaniel Stenberg2015-05-121-3/+4
| | | | | | 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.
* hostip: fix compiler warningsDaniel Stenberg2015-04-031-36/+1
| | | | introduced in the previous mini-series of 3 commits
* actually implement CURLOPT_RESOLVE removalsStefan Bühler2015-04-031-4/+38
| | | | - also log when a CURLOPT_RESOLVE entry couldn't get parsed
* move Curl_share_lock and ref counting into Curl_fetch_addrStefan Bühler2015-04-031-20/+52
|
* fix refreshing of obsolete dns cache entriesStefan Bühler2015-04-031-38/+32
| | | | | | | | | | | | - 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
* checksrc: use space after commaDaniel Stenberg2015-03-171-1/+1

* hostip: Fix signal race in Curl_resolv_timeout.Tobias Stoeckmann2015-03-141-26/+27
| | | | | | | | | | | | | | | | | | | 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.
* mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg2015-03-031-4/+1
| | | | | ... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
* hostip: remove 'stale' argument from Curl_fetch_addr protoDaniel Stenberg2015-01-071-11/+10
| | | | | 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.
* code/docs: Use correct case for IPv4 and IPv6Steve Holme2014-12-271-2/+2
| | | | | | 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.
* resolve: cache lookup for async resolversMichael Wallner2014-08-311-23/+48
| | | | | | | | | | 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.
* hostip: don't remove DNS entries that are in useRomulo A. Ceccon2014-01-281-1/+1
| | | | | | | | 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
* hostip: don't prune DNS cache entries that are in useDaniel Stenberg2013-11-251-4/+9
| | | | | | | | | | 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
* global dns cache: fix memory leakDaniel Stenberg2013-08-081-0/+4
| | | | | The take down of the global dns cache didn't take CURLOPT_RESOLVE names into account.
* global dns cache: didn't work [regression]Daniel Stenberg2013-08-081-12/+15
| | | | | | | | | 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
* build: fix circular header inclusion with other packagesYang Tse2013-01-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* build: make use of 76 lib/*.h renamed filesYang Tse2012-12-281-13/+13
| | | | | | 76 private header files renamed to use our standard naming scheme. This change affects 322 files in libcurl's source tree.
* setup_once.h: refactor inclusion of <unistd.h> and <sys/socket.h>Yang Tse2012-12-141-6/+0
| | | | Inclusion of top two most included header files now done in setup_once.h
* fixed memory leak: CURLOPT_RESOLVE with multi interfaceDaniel Stenberg2012-11-181-2/+6
| | | | | | | | | | 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

* CURLOPT_RESOLVE: avoid adding already present host namesDaniel Stenberg2011-12-311-0/+66
| | | | | | | 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.
* resolve: don't leak pre-populated dns entriesDaniel Stenberg2011-12-231-0/+21
| | | | | | | | | 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"
* hostip.c: return immediately from Curl_resolv_timeout() upon expired timeout.Yang Tse2011-09-011-0/+4
| | | | | | | | Ensure existing logic in Curl_resolv_timeout() is not subverted upon getting a negative timeout from resolve_server(). The timeout in resolve_server() could be checked to avoid calling Curl_resolv_timeout() with an expired timeout, but fixing this in this way allows existing logic in resolve_server() to be kept unchanged.
* stdio.h, stdlib.h, string.h, stdarg.h and ctype.h inclusion done in setup_once.hYang Tse2011-07-261-6/+0

* source cleanup: unify look, style and indent levelsDaniel Stenberg2011-04-271-3/+3
| | | | | By the use of a the new lib/checksrc.pl script that checks that our basic source style rules are followed.
* hostip: comment fixed to state current situationDaniel Stenberg2011-04-251-2/+4
|
* async resolvers: further cleanupsDaniel Stenberg2011-04-251-2/+2
| | | | | | | | 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.
* fix compiler warning: conversion may lose significant bitsYang Tse2010-12-011-1/+2

* hostip: edit commentYang Tse2010-11-261-1/+1
|
* ip_version: moved to connection structDaniel Stenberg2010-11-111-1/+1
| | | | | | | | | 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.
* CURLOPT_RESOLVE: addedDaniel Stenberg2010-11-081-3/+3
| | | | | | | | | | | | CURLOPT_RESOLVE is a new option that sends along a curl_slist with name:port:address sets that will populate the DNS cache with entries so that request can be "fooled" to use another host than what otherwise would've been used. Previously we've encouraged the use of Host: for that when dealing with HTTP, but this new feature has the added bonus that it allows the name from the URL to be used for TLS SNI and server certificate name checks as well. This is a first change. Surely more will follow to make it decent.
* fix compiler warning: variable might be clobbered by longjmp or vforkYang Tse2010-04-131-2/+2
