Travis is failing #53

Closed JJ closed 5 years ago

JJ commented 5 years ago

And it seems to be simply due to the use of pack. Should be easy to solve.

paultcochrane commented 5 years ago

Actually, the problem seems to be due to the FastCGI dependency:

===> Install [FAIL] for FastCGI:ver<0.9.0>: ===SORRY!=== Error while compiling /home/travis/build/perl6/perl6-examples/site#sources/D33B2CF81EB010BB6A219D2AF5F873163A6DBF44 (FastCGI::Protocol)

A git grep in the perl6-examples code doesn't show up any use of pack, so my guess is that the problem is really upstream.

JJ commented 5 years ago

Right... And it remains to be seen whether FastCGI is actually used, too...

paultcochrane commented 5 years ago

What's really weird is that FastCGI doesn't actually turn up in the dependency chain (as far as I can tell):

zef depends .

This is weird...

Anyway, I've pushed some commits to fix other issues I noticed with the current code, so maybe the next build will use an up to date dependency list and the problem with FastCGI will solve itself. The build will still fail since there is currently a bug in Rakudo, see e.g. https://colabti.org/irclogger/irclogger_log/perl6?date=2019-01-01#l430. Given sufficient tuits, I'll submit a patch for that issue and see if it can get patched.

paultcochrane commented 5 years ago

Hrm, hope is not a strategy :-/ For some reason FastCGI is still found as a dependency on Travis. The odd thing is that I can't reproduce this in my environment (Debian stretch; moar, nqp, rakudo, zef built and installed from source), which I think should be sufficently similar to the environment on Travis.

paultcochrane commented 5 years ago

It looks like bug I mentioned above has been fixed in a recent Rakudo commit. Unfortunately, the Travis tests are still failing sometimes due to a flappy test in the perl6-examples code...

JJ commented 5 years ago

Thanks, Paul, for taking care of this...

dwarring commented 5 years ago

Bumped to Rakudo 2018.05 for Pod::To::HTML and friends (2b9742a ). Also fixed a 50/50 chance of 070-categories.t failing due to unstable ordering in Categories.categories-list (bb38add).

paultcochrane commented 5 years ago

@dwarring Thanks for getting the tests passing again! Do you know what was causing the error when installing Pod::To::HTML? I hadn't yet managed to work out what 

No such method 'new-without-check' for invocant of type 'CompUnit::PrecompilationId'

meant.

JJ commented 5 years ago

There''s been some change lately in that part of Rakudo, but I didn't know there was an error in Pod::To::HTML. I'll have to check that out.

Pod::To::HTML needs a minimum 2018.11 version, actually, since it's using the latest additions to the Pod parsing code...

paultcochrane commented 5 years ago

Interesting... Should Pod::To::HTML perhaps specify 6.d as the version as the Perl version requirement in its metadata? That way dependent packages can use the correct version requirements. Just a thought...

JJ commented 5 years ago

2018.11 is not 6.d yet, I think, but I guess specifying a minimum version is a must anyway.

dwarring commented 5 years ago

Fwiw, Pod::To::HTML is used by htmlify.pl to generate HTML. Does at least run to completion on Rakudo 2018.05, after installing the latest Pod::To::HTML.

paultcochrane commented 5 years ago

@JJ Travis is back green again. Are you happy that this issue is resolved?

JJ commented 5 years ago

Totally! Great work!
