David Drysdale	7e17c22b0f	Use "resolve" as synonym of "dns" in nsswitch.conf Modern Linux systems may have libnss_resolve from systemd as the resolver, which is then configured in /etc/nsswitch.conf with the "resolve" keyword rather than "dns". Fixes #33	9 years ago
David Drysdale	56cd98b9e4	test: Update init tests to match behaviour Unreadable config files are now treated the same way as absent config files.	9 years ago
Andrew Ayer	11e37a92ef	Add ares_set_socket_configure_callback() This function sets a callback that is invoked after the socket is created, but before the connection is established. This is an ideal time to customize various socket options.	9 years ago
David Drysdale	87d641a907	test: ares_set_socket_callback failure behaviour	9 years ago
David Drysdale	2bae2d56d7	test: Check ares_parse_txt_reply_ext() entrypoint	9 years ago

David Drysdale	86beb81892	test: More initialization tests	9 years ago
David Drysdale	ff1f7a1c3c	test: Improve containerized test mechanism Aim is to ensure that code coverage information can escape the container. To do this: - Enter a new mount namespace too, so that we can... - Bind mount the expected source directory into the container - Share memory with the sub-process so coverage information is shared too.	9 years ago
David Drysdale	b644412a66	test: Make contained tests easier to write	9 years ago
David Drysdale	5dc450a4b3	test: Add framework for containerized testing On Linux we can potentially use user and UTS namespaces to run a test in a pseudo-container with: - arbitrary filesystem (e.g. /etc/resolv.conf, /etc/nsswitch.conf, /etc/hosts) - arbitrary hostname/domainname. Include a first pass at the framework code to allow this, along with a first test case that uses the container.	9 years ago
David Drysdale	439eb45cc0	test: Use a longer timeout for less flakiness Having occasional test failures from timeout before multiple queries can complete, so up the default timeout for the test from 100ms to 1500ms.	9 years ago
David Drysdale	78f9ec5515	test: Make failure tests more robust Different platforms will do different numbers of allocations in the processing of a given API call; just check that the return code is either success or ENOMEM, and free off any returned state in the former case. Also cope with ECONNREFUSED as well as ENOTFOUND.	9 years ago
David Drysdale	3478963873	test: Get test code building under Windows - Initial nmake file based off library nmake file - Cast socket call arguments to (char *) - Use wrapper sclose() that maps to closesocket() or close() - Build a config.h indicating presence of headers - Conditionally include netdb.h - Remove unnecessary include of sys/socket.h - Force longer bitmask for allocation failure tracking - Call WSAStartup() / WSACleanup() in main() - Set TCP_NODELAY for mock server - Turn on tests in AppVeyor build	9 years ago

David Drysdale	9edf9411c7	test: Add a simple multi-server test Check rotate option does something	9 years ago
David Drysdale	d448d6604f	test: Allow for multiple mock servers - Update the MockServer to allow separate specification of UDP and TCP ports - Have an array of mock servers listening on consecutive sets of ports. - Rename Process(fd) to ProcessFD(fd) to avoid confusion. - Initialize channel by using the new ares_set_servers_ports() entrypoint, so multiple ports on the same loopback address can be used.	9 years ago
David Drysdale	92656bcc82	test: Update test for set/get_servers variants Ports are significant in the _ports_ variant functions, so update test to cope.	9 years ago
David Drysdale	3231480a85	test: Make GetNameServers() utility function port-aware Also make it generally available.	9 years ago
David Drysdale	e26a678f26	test: more testing, including of internal static functions	9 years ago
David Drysdale	25adcc413e	test: more tests, especially fallback processing - Make mock server listen on UDP + TCP in parallel. - Test UDP->TCP fallback on truncation - Test EDNS->no-EDNS fallback - Test some environment init options - Test nonsense reply test: short response	9 years ago
David Drysdale	a05f240dea	test: more tests, particularly of initialization	9 years ago
David Drysdale	83839fde7a	test: Run mock tests over both TCP and UDP With the exception of a few tests that make use of the timed retry aspect of UDP.	9 years ago

David Drysdale	af3ee9a8ba	test: Add initial unit tests for c-ares library The tests are written in C++11, using the GoogleTest and GoogleMock frameworks. They have their own independent autoconf setup, so that users of the library need not have a C++ compiler just to get c-ares working (however, the test/configure.ac file does assume the use of a shared top-level m4/ directory). However, this autoconf setup has only been tested on Linux and OSX so far. Run with "./arestest", or "./arestest -v" to see extra debug info. The GoogleTest options for running specific tests are also available (e.g. "./arestest --gtest_filter=Live"). The tests are nowhere near complete yet (currently hitting around 60% coverage as reported by gcov), but they do include examples of a few different styles of testing: - There are live tests (ares-test-live.cc), which assume that the current machine has a valid DNS setup and connection to the internet; these tests issue queries for real domains but don't particularly check what gets returned. The tests will fail on an offline machine. - There a few mock tests (ares-test-mock.cc) that set up a fake DNS server and inject its port into the c-ares library configuration. These tests allow specific response messages to be crafted and injected, and so are likely to be used for many more tests in future. - To make this generation/injection easier, the dns-proto.h file includes C++ helper classes for building DNS packets. - Other library entrypoints that don't require network activity (e.g. ares_parse__reply) are tested directly. - There are few tests of library-internal functions that are not normally visible to API users (in ares-test-internal.cc). - A couple of the tests use a helper method of the test fixture to inject memory allocation failures, using the earlier change to the library to allow override of malloc/realloc/free. - There is also an entrypoint to allow Clang's libfuzzer to drive the packet parsing code in ares_parse__reply, together with a standalone wrapper for it (./aresfuzz) to allow use of afl-fuzz for further fuzz testing.	9 years ago
David Drysdale	148b6e93b9	test: Add local copy of GoogleMock/GoogleTest 1.7.0 Don't check in gtest/m4 files, as they are unused and interfere with the top-level configure process.	9 years ago
