Brad House	d3642a6aeb	CI: Move some Appveyor builds to GitHub actions (#791 ) AppVeyor has gotten progressively slower over the last year or so. Move some Windows builds to GitHub actions which is considerably faster. Fix By: Brad House (@bradh352)	5 months ago

Brad House	4248c642d2	Enable QueryCache by default (#786 ) The query cache should be enabled by default. This will help with determining proper timeouts for #736. It can still be disabled by setting the ttl to 0. There should be no negative consequences of this in real-world scenarios since DNS is based on the TTL concept and upstream servers will cache results and not recurse based on this information anyhow. DNS queries and responses are very small, this should have negligible impact on memory consumption. Fix By: Brad House (@bradh352)	5 months ago
Brad House	5804b30a87	CMAKE: Some systems might expect configure macros to be defined to 1 On some broken MacOS SDK versions, if HAVE_UNISTD_H is defined, it must be defined to 1, otherwise it will cause build errors. Autotools always defines to 1, but CMake doesn't. Fixes Issue: #787 Fix By: Brad House (@bradh352)	5 months ago
Brad House	266599a632	Windows: Reload config on manual DNS changes (#785 ) The `NotifyIpInterfaceChange()` method only notifies of automatic changes, such as via DHCP or interfaces going up or down. However, someone editing the DNS settings manually would not trigger a notification. Use `RegNotifyChangeKeyValue()` to monitor `HKLM\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\Interfaces` and `HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces` to pick up these changes. This new check also works when using the OpenWatcom compiler as the symbols are available, so they have been enabled (though `NotifyIpInterfaceChange()` method is disabled for OpenWatcom still due to the linker libraries missing this symbol). NOTE: it does appear that about 5 events get triggered for some reason, it doesn't seem to hurt anything, but it will actually cause it to re-read the configuration multiple times.

Brad House	c0d41d08ab	Coverage code annotations for identification of desirable paths that need testing (#775 ) Add code annotations for ignoring specific code paths for coverage calculations. The primary purpose of this is to make it easy to see the code paths that we could (and probably should) write test cases for, as these would have the most impact on delivery of a stable product. The annotations used are: `LCOV_EXCL_LINE: <designation>`, `LCOV_EXCL_START: <designation>`, `LCOV_EXCL_STOP` Unfortunately `LCOV_EXCL_BR_LINE` does not appear to be supported by coveralls as it would have been a more elegant solution over START/STOP. We specifically include the `<designation>` not just for future reference but because it makes it easy to identify in case we want to address these conditions in a different way in the future. The main areas designated for exclusion are: 1. `OutOfMemory` - these are hard to test cases, and on modern systems, are likely to never occur due to optimistic memory allocations, which can then later cause the kernel to terminate your application due to memory not actually being available. c-ares does have some testing framework for this, if we wish to expand in the future, we can easily use sed to get rid of of these annotations. 2. `DefensiveCoding` - these are impossible to reach paths at the point in time the code was written. They are there for defensive coding in case code is refactored in the future to prevent unexpected behavior. 3. `UntestablePath` - these are code paths that aren't possible to test, such as failure of a system call. 4. `FallbackCode` - This is an entire set of code that is untestable because its not able to simulate a failure of the primary path. This PR also does add some actual coverage in the test cases where it is easy to do. Fix By: Brad House (@bradh352)	5 months ago

Brad House	6129d9b79f	Basic support for SIG RR record (RFC 2931 / RFC 2535) (#773 ) With the current c-ares parser, as per PR #765 parsing was broken due to validation that didn't understand the `SIG` record class. This PR adds basic, non validating, and incomplete support for the `SIG` record type. The additional `KEY` and `NXT` which would be required for additional verification of the records is not implemented. It also does not store the raw unprocessed RR data that would be required for the validation. The primary purpose of this PR is to be able to recognize the record and handle some periphery aspects such as validation of the class associated with the RR and to not honor the TTL in the RR in the c-ares query cache since it will always be 0.
