When building capnproto v0.9.1 for the package for ALT Linux we got such make check error:

[ TEST ] kj/async-io-test.c++:307: legacy test: AsyncIo/AncillaryMessageHandler

That's odd. What kernel version?

[vt-alt]

Tested on 4.9.56.

[kentonv]

I'm not sure what to say here. Seems like your kernel is behaving unusually. You can safely ignore the test failure as this particular functionality isn't really used by Cap'n Proto itself.

Thanks. Maybe we could reproduce the test with this line resolved

if you suggest how?

But, if this really does not matter, could you suggest the way to skip this test? I am not familiar with your test harness, but would like to leave make check run on package build.

[kentonv]

Sorry, the stack trace probably doesn't help me (even if I could decode it). This probably needs to be debugged directly on a system exhibiting the problem.

Do you have the ability to float patches on your packages? If so I'd suggest adding #if 0 around this test case. Otherwise, I'd accept a PR which adds something like #if KJ_SKIP_CMSG_HANDLER_TEST around that test, and then you can add that to your cflags when you build...

Thanks for explanations! I did sed -i '/TEST(AsyncIo, AncillaryMessageHandler)/,/^}/s/^/\/\//' c++/src/kj/async-io-test.c++ .
