test_resolve.cpp fails #52

I have compiled inside a docker container with G++11. After running the tests, all but a single fail is observed. The test output below:

root@a100cse:/localscratch/senders-io/build/tests# ./test_sio

Interesting. I will look into that.

It might be due to a minimal /etc/services file. Can you post its content here, please? It might be better to change the test from using service "http" to some numerical string such as "80" (or anything else). In fact it might show that an overload is needed without a specified service, since that is a optional for the underlying calls.

/etc/services was missing. apt install netbase fixed the issue. Thanks. I guess docker environments can be really different compared to bare metal Linux installations.

maikel commented 1 year ago

The test just assumed /etc/services to exists which might be bad. I will fix that.
