Brad House	7283230f97	CI: MacOS: move to GitHub Actions instead of Cirrus-CI (#825 ) We've been using a lot of time on Cirrus-CI and our credits run out quickly. MacOS costs 15 compute credits vs 3 compute credits for Linux. Move MacOS testing to GitHub Actions. Fix By: Brad House (@bradh352)	7 months ago
Brad House	a1d1d48cb9	test: ServerFailoverOpts can fail on heavily loaded systems due to its reliance on sleep and time. Try to harden it a little bit	7 months ago
Brad House	1cf71ee166	CMake MSVC Parallelizm issue: Don't build adig and ahost simultaneously Make ahost a dependency of adig to prevent issues with them both referencing ares_strcasecmp.c and ares_getopt.c. This appears to be a bug in the Cmake generator for MSVC project files. Fixes #796 Fix By: Brad House (@bradh352)	7 months ago
Brad House	8626edda0a	mem leak due to `ares__hosts_entry_to_hostent()` allocation strategy (#824 ) `ares__hosts_entry_to_hostent()` would allocate a separate buffer for each address, but `ares_free_hostent()` expects a single allocation to hold all addresses. This PR fixes this issue and simplifies the logic by using the already-existing `ares__addrinfo2hostent()` to write the hostent instead of coming up with yet another way to write the structure.

Brad House	501213a2e4	clang static analyzer: silence warning	7 months ago
Brad House	5fb9ef4fb6	UDP write may fail indicating host isn't reachable (#821 ) UDP is connectionless, but systems use ICMP unreachable messages to indicate there is no ability to reach the host or port, which can result in a `send()` returning an error like `ECONNREFUSED`. We need to handle non-retryable codes like that to treat it as a connection failure so we requeue any queries on that connection to another connection/server immediately. Otherwise what happens is we just wait on the timeout to expire which can greatly increase the time required to get a definitive message. This also adds a test case to verify the behavior.

Brad House	a499c1a1c3	Prevent complex recursion during query requeing and connection cleanup c-ares utilizes recursion for some operations, and some of these processes can have unintended side effects, such as if a callback is called that then recurses into the same function. This can cause strange cleanup conditions that lead to crashes. Try to disassociate queries with connections as early as possible and move cleaning up unneeded connections to its own scan rather than trying to detect each time a query is disassociated from a connection.

Brad House	6408e5f2ef	Propagate record duplication error code (#820 ) In c-ares 1.30.0 we started validating strings parsed are printable. This caused a regression in a pycares test case due to a wrong response code being returned as the error was being propagated from a different section of code that was assuming the only possible failure condition was out-of-memory. This PR adds a fix for this and also a test case to validate it. Ref: https://github.com/saghul/pycares/issues/200 Fix By: Brad House (@bradh352)	7 months ago

Brad House	51cfc6235a	ares_destroy() deadlock during cleanup of config change monitoring if a configuration change comes in during shutdown	7 months ago
Brad House	ee7a9446a9	Rework WinAFD event code (#811 ) We've had reports of user-after-free type crashes in Windows cleanup code for the Event Thread. In evaluating the code, it appeared there were some memory leaks on per-connection handles that may have remained open during shutdown, while trying to resolve that it became apparent the methodology chosen may not have been the right one for interfacing with the Windows AFD system as stability issues were seen during this debugging process. Since this system is completely undocumented, there was no clear resolution path other than to switch to the other methodology which involves directly opening `\Device\Afd`, rather than spawning a "peer socket" to use to queue AFD operations. The original methodology chosen more closely resembled what is employed by [libuv](https://github.com/libuv/libuv) and given its widespread use was the reason it was used. The new methodology more closely resembles [wepoll](https://github.com/piscisaureus/wepoll). Its not clear if there are any scalability or performance advantages or disadvantages for either method. They both seem like different ways to do the same thing, but this current way does seem more stable. Fixes #798 Fix By: Brad House (@bradh352)	7 months ago
