Brad House	2250b598fe	Android variants may not have __system_property_get Some android systems like ARM64 may not have the __system_property_get symbol in libc (but still have it in the public headers). Detect this condition at build time. The __system_property_get method of retrieving name servers is deprecated as of Oreo so should strictly be a fallback mechanism anyhow.	7 years ago

Brad House	919dc45f2f	Portability updates for legacy systems. (#92 ) Socklen_t should not be used in code, instead ares_socklen_t should be used. Convert ssize_t to ares_ssize_t for portability since the public API now exposes this.	8 years ago
Brad House	39aeafd27d	Windows DNS server sorting (#81 ) Original Patch From Brad Spencer: https://c-ares.haxx.se/mail/c-ares-archive-2016-04/0000.shtml My modifications include: * Dynamically find GetBestRoute2 since it is a Windows Vista+ symbol, and will fall back to prior behavior when not available. * Prefer get_DNS_AdaptersAddresses as the modifications should alleviate the concerns which caused us to prefer get_DNS_NetworkParams * Update AppVeyor to use MinGW-w64 instead of the legacy MinGW * Fix compile error in test suite for Windows. Original message from patch below: From: Brad Spencer <bspencer@blackberry.com> Date: Fri, 29 Apr 2016 14:26:23 -0300 On Windows, the c-ares DNS resolver tries first to get a full list of DNS server addresses by enumerating the system's IPv4/v6 interfaces and then getting the per-interface DNS server lists from those interfaces and joining them together. The OS, at least in the way the c-ares prefers to query them (which also may be the only or best way in some environments), does not provide a unified list of DNS servers ordered according to "current network conditions". Currently, c-ares will then try to use them in whatever order the nested enumeration produces, which may result in DNS requests being sent to servers on one interface (hosting the current default route, for example) that are only intended to be used via another interface (intended to be used when the first interface is not available, for example). This, in turn, can lead to spurious failures and timeouts simply because of the server address order that resulted because of the enumeration process. This patch makes the (safe?) assumption that there is no other better rule to chose which interface's DNS server list should be prioritized. After all, a DNS lookup isn't something "per network"; applications don't look up "these DNS names on this interface and those DNS names on that interface". There is a single resource pool of DNS servers and the application should presume that any server will give it the "right" answer. However, even if all DNS servers are assumed to give equally useful responses, it is reasonable to expect that some DNS servers will not accept requests on all interfaces. This patch avoids the problem by sorting the DNS server addresses using the Windows IPv4/v6 routing tables. For example, a request to DNS server C on interface 2 that is actually sent over interface 1 (which may happen to have the default route) may be rejected by or not delivered to DNS server C. So, better to use DNS servers A and B associated with interface 1, at least as a first try. By using the metric of the route to the DNS server itself as a proxy for priority of the DNS server in the list, this patch is able to adapt dynamically to changes in the interface list, the DNS server lists per interface, which interfaces are active, the routing table, and so on, while always picking a good "best" DNS server first. In cases where any DNS server on any interface will do, this patch still seems useful because it will prioritize a lower-metric route's (and thus interface's) servers.	8 years ago

Stephen Sorley	10cb4b437f	Updated CMake minimum version to 2.8.12. Changed the way usage requirements (include dirs, compile defs, dependent libraries) are specified, to match the recommended standard practice for modern CMake. This involves using target-specific functions (target_include_directories, target_compile_definitions, etc.), along with the PUBLIC, PRIVATE or INTERFACE modifiers. Updated chain-building support to imitate new-style Find modules (import libs), instead of old-style Find modules (cache variables).	8 years ago

Brad House	7518c26d8e	XCode v8 introduced clock_gettime() for iOS v10. However, it is a weak symbol, which means when earlier iOS versions try to use clock_gettime() it results in a crash due to the missing symbol. Detect this condition and do not set HAVE_CLOCK_GETTIME_MONOTONIC.	8 years ago
Brad House	e4fe33edb7	Adds cmake build system support to C-Ares. The patch does not modify any source files, it only adds 3 new files (CMakelists.txt, ares_build.h.cmake, ares_config.h.cmake) which form the build system. I've tried to go through as much of the autotools tests and extracted what I thought was appropriate, though many of the tests aren't as in-depth in CMake as they are for autotools ... it is unclear why some of them exist at all, I'm guessing for legacy systems that CMake probably doesn't support anyhow. Building the library, and examples (adig, ahost, acountry) plus installation should work across a large number of tested platforms. The tests have not yet been integrated.	8 years ago
