Brad House	3db69bbfeb	Fix Windows UWP (Store) building and add to CI/CD (#627 ) When building for UWP (WindowsStore), additional headers are needed and some functions are not available. This also adds AppVeyor CI/CD support to catch these issues in the future. Fix By: Deal (@halx99) and Brad House (@bradh352)	1 year ago
Brad House	320cefe1c7	ares_set_servers_() should allow an empty server list For historic reasons, we have users depending on ares_set_servers_() to return ARES_SUCCESS when passing no servers and actually clear the server list. It appears they do this for test cases to simulate DNS unavailable or similar. Presumably they could achieve the same effect in other ways (point to localhost on a port that isn't in use). But it seems like this might be wide-spread enough to cause headaches so we just will document and test for this behavior, clearly it hasn't caused "issues" for anyone with the old behavior.

Brad House	4982f76a2f	Query Cache support (#625 ) This PR implements a query cache at the lowest possible level, the actual dns request and response messages. Only successful and `NXDOMAIN` responses are cached. The lowest TTL in the response message determines the cache validity period for the response, and is capped at the configuration value for `qcache_max_ttl`. For `NXDOMAIN` responses, the SOA record is evaluated. For a query to match the cache, the opcode, flags, and each question's class, type, and name are all evaluated. This is to prevent matching a cached entry for a subtly different query (such as if the RD flag is set on one request and not another). For things like ares_getaddrinfo() or ares_search() that may spawn multiple queries, each individual message received is cached rather than the overarching response. This makes it possible for one query in the sequence to be purged from the cache while others still return cached results which means there is no chance of ever returning stale data. We have had a lot of user requests to return TTLs on all the various parsers like `ares_parse_caa_reply()`, and likely this is because they want to implement caching mechanisms of their own, thus this PR should solve those issues as well. Due to the internal data structures we have these days, this PR is less than 500 lines of new code. Fixes #608 Fix By: Brad House (@bradh352)	1 year ago

Brad House	a3631763ca	Fix /etc/hosts processing performance with all entries using same IP address Some users use blacklist files like https://github.com/StevenBlack/hosts which can contain 200k+ host entries all pointing to 0.0.0.0. Due to the merge logic in the new hosts processor, all those entries will be associated as aliases for the same ip address. The first issue is that it attempts to check the status of all the hosts for the merged entry, when it should only be checking the new hosts added to the merged entry, so this caused exponential time as the entries got longer. The next issue is if searching for one of those hosts, it would append all the matches as cnames/aliases, but there is zero use for 200k aliases being appended to a lookup, so we are artificially capping this to 100.

Ignat	7a140cb478	Randomize retry penalties to prevent thundering herd type issues (#606 ) The retry timeout values were using a fixed calculation which could cause multiple simultaneous queries to timeout and retry at the exact same time. If a DNS server is throttling requests, this could cause the issue to never self-resolve due to all requests recurring at the same instance again. This PR also creates a maximum timeout option to make sure the random value selected does not exceed this value. Fix By: Ignat (@Kontakter)	1 year ago

Brad House	0cc570eabe	Implement ares_reinit() to reload system configuration into existing channel (#614 ) This PR implements ares_reinit() to safely reload a channel's configuration even if there are existing queries. This function can be called when system configuration is detected to be changed, however since c-ares isn't thread aware, care must be taken to ensure no other c-ares calls are in progress at the time this function is called. Also, this function may update the open file descriptor list so care must also be taken to wake any event loops and reprocess the list of file descriptors.
