Failed test installing with zef: Sending non-SSL to SSL socket...

[MorayJ]

I'm trying to install IRC::Client and this is a dependency. I get this failed test, and then it appears to hang.

===> Testing: IO::Socket::Async::SSL:ver<0.7.0>
# Failed test 'Sending non-SSL to SSL socket does not hang (connection closed)'
# at t/bad-incoming.t line 25
# Looks like you failed 1 test of 3

I am on:
This is Rakudo version 2018.06-369-gfa73bb4 built on MoarVM version 2018.06-391-g91d2878
implementing Perl 6.c.

This happened for me too. I'm on:

This is Rakudo version 2018.12 built on MoarVM version 2018.12
implementing Perl 6.d.

This happened to me too, on Raspbian GNU/Linux 10 (buster), MoarVM version 2018.12:

===> Testing: IO::Socket::Async::SSL:ver<0.7.4>
# Failed test 'Sending non-SSL to SSL socket does not hang (connection closed)'                                                      
# at t/bad-incoming.t line 25
# Looks like you failed 1 test of 3

After this line, nothing happens but the process still uses 100% cpu.

You'll need a newer MoarVM to do this, but: but running it under the debugger (for example, in Comma IDE), pausing it when it hangs, and seeing what's on the stack could provide useful information. Other things to check:

• Does it work on a more recent Rakudo version?
• What version of the OpenSSL library?

Hi,
I am seeing this same failure on a Raspberry Pi 3B+. System info:

$ uname -srmo
Linux 4.19.114-1-ARCH armv7l GNU/Linux
$ rakudobrew current
Currently running moar-blead
$ raku --version
This is Rakudo version 2020.02.1-338-gb0a720cb6 built on MoarVM version 2020.02.1-107-gab089e947
implementing Raku 6.d.
$ openssl version
OpenSSL 1.1.1f  31 Mar 2020

This is in fact the first test of the first testfile that is failing.

Here is what I have so far, with the OpenSSL dependency being installed and tested ok with no errors:

$ git clone https://github.com/jnthn/p6-io-socket-async-ssl.git

The stacktrace is here:

And I have uploaded the coredump here: https://send.firefox.com/download/084116f5fce0768c/#_VMlaPLI5roJiDixTyCQqw
The firefox send link needs a password, pm me for that if you'd like the dump I'm happy to share it (just not publicly).

Other checks:
I have made sure that the OpenSSL raku module functions ok by using it directly, and as far as I can tell it does.

Looking at the stack trace - which I'm not very adept at reading - it could be related to threading? Not sure though to be honest. Let me know if there's anything else I can do to help debug.

Thanks for all the great work on raku!
Regards,
Mark.
