This example gives the following errors:

Internal Error: 'server returned no data'

I'm using OS X Sierra.

Perl6 version:

perl6 -v
This is Rakudo Star version 2018.01 built on MoarVM version 2018.01
implementing Perl 6.c.

I hate to say "it works for me", but it does :-)

This is reminiscent of a failure that happens when the SSL handshake fails and IIRC this is possible if the server name extension isn't implemented in the version of OpenSSL. Do you know what version of OpenSSL you have installed, and is it possible to upgrade it?

[johnsaigle]

@jonathanstowe You could be right that this is an OpenSSL issue -- however I am working on OS X and afaik Apple uses its own TLS libraries for... things?

I've been trying to get help for this on the #perl6 irc channel and on StackOverflow which led to @zoffixznet creating this Gist.

On running it, I got this output:

===> Testing [FAIL]: HTTP::UserAgent:ver<1.1.39>:auth<github:sergot>

If this is an OpenSSL issue, is there something, somewhere in Perl6 or this module that requires its use vs. the OS X default? Am I missing something? I'm not sure how far upstream this problem is or if it's so specific to my computer that I can't find a solution.

Even upgrading OpenSSL on OS X seems to be non trivial.

I just wanna use Perl6! 😅 Any help at all would be appreciated but I understand if this is issue is too niche to assist me with...
