Jupyter::Kernel

[AlexDaniel]

Module Jupyter::Kernel cannot be installed (Flapper), perhaps it has some failing tests.

• Tickets are opened/closed in this repo automatically (though not immediately).
• If you can install the module without any problems, add works for me label, leave a comment saying that it works for you and mention any details that you feel are important.
• If it needs a native library, put native dependency label, describe what you did to install it and ensure that same instructions are present in the README file of the module (otherwise submit a pull request). Also try to update this wiki page.
• If the module is broken, try to fix it and send a PR. Add PR sent label.
• If there is a problem in one of the dependencies, add failing dependency label and write a comment explaining the situation. Feel free to work on the corresponding ticket for the failing dependency.
• It is a good idea to assign yourself to this ticket if you're working on it (to make sure two or more people are not working on the same ticket at the same time).
• Once you are done, search for a next ticket.

If you can't self-assign yourself or attach a label, please let us know on #perl6 channel on freenode or just leave a comment here. We will try to give you privileges as fast as possible.

I see this is closed but I'll comment anyway -- I couldn't reproduce this -- looks like maybe it's just that the first run takes too long (precompilation?)

[AlexDaniel]

@bduggan this is an actual issue and it was closed by “mistake”. In the OP it says that the status is Flapper, meaning that it succeeds sometimes but other times it fails. It was closed because on the most recent run in succeeded (just luck), so it was closed automatically.

looks like maybe it's just that the first run takes too long (precompilation?)

No. It segfaulted. See this:

  Non-zero wait status: 11

That's a segfault. I don't know if there's an issue with Rakudo or with this module, but it's not OK.

[AlexDaniel]

Also, if you have troubles reproducing this, I recommend something like:

time while PERL6LIB=lib/ prove --exec=perl6 t/; do :; done

That is, keep running the tests until it fails.
