ipv6 disabled on kernel cmdline disrupts Tox = most tests fail

ipv6 disabled on kernel cmdline disrupts Tox and most tests fail

Boot a linux with ipv6.disable=1 and run the testsuite

17% tests passed, 43 tests failed out of 5

All the tests fail all at the same place.

 new_networking_ex:     failed to get a socket?! 97, Address family not supported by protocol

Note that this is on a build with USE_IPV6 "Use IPv6 in tests" OFF in the CMakeLists.txt which just disables tests - no change to the library I think.

As most of the tests fail if you boot a linux with ipv6.disable=1 and run the testsuite, booting a vm with ipv6.disable=1 should be a test.

19% tests passed, 42 tests failed out of 52

The errors in the current build all fail at:

ERROR network.c:1169   new_networking_ex: failed to get a  socket?! 97, Address family not supported    by protocol 

Does anyone have a Vagrant file for spinning up machines to test Tox with different command lines?

A year later and 2/2 more tests failed:

19% tests passed, 44 tests failed out of 54

Interesting. I'll look into adding a qemu VM with Linux and ipv6 disabled. The code can deal with ipv6 not being provisioned, but maybe not with it being absent entirely.

[emdee-is]

A qemu VM with Linux and ipv6 disabled would be really nice - it's black and white for me: I reboot the same system and run the same code the tests run clean.

Thing is, it means I'm working in a greyzone: I've doing ctypes wrapping of the library into Python which will SEGV if you get it wrong. And I'm running that under a Qt GUI which is reported to SEGV on exit if it feels like it.

I'll appreciate the test coverage.

I disabled ipv6 on my nixos using networking.enableIPv6 = false; and ran ctest.

local_discovery timing out seems to be normal. but that network fail is worrying.

thanks - my tests give more dramatic results; bear in mind i don't know C or ctest: does subprocess aborted mean a SEGv?

What does auto_tests/auto_network_test do? It does nothing for me and returns 0:
