For UDP tests, there's a chance of a retry. EXPECT_CALL only
expects a single request to arrive at the server; ON_CALL allows
for a UDP retry and repeats the same answer.
Note that ON_CALL and EXPECT_CALL can't be mixed in the same
test, and that tests that have a varied sequence of responses
for the same repeated request still have to use EXPECT_CALL.
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
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.
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.
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.
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.
- 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
- 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.
- 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
