'make test' runs all the network tests.

Some of the tests in test_ssl fail instead of skip if is not accessible.

$ ./python -m test -v -u all test_ssl

The attached patch should fix the test failures.

I tested the attached patch on latest cpython master and it works for me.

The two changes to look okay to me, although they will need updating since the Issue 24841 changeover to

But I don’t think it is a good idea to add ENOTCONN to the list of errors ignored by all transient_internet() tests. In most cases, ENOTCONN suggests a programming error, not a network problem. I think a better solution would be to call connect_ex() again in test_non_blocking_connect_ex(), and retrieve the result (probably also ECONNREFUSED like the other failures, or 0 if successful).

I think you meant issue 25940, right? :)

Do you want me to wait for issue 25940?

Yes sorry I did mean Issue 25940 (too many bug numbers!), but only the main change which has already been made (revision adf750b1252d etc). So you don’t have to wait for that.

test_ssl doesn't use anymore and it now better handle network failures. I close the issue as out of date.
