Include test coverage numbers from cpancover

[szabgab]

I've just added this to https://cpan-digger.perlmaven.com/ and it would be nice to add it here too.

my $cover = $mcpan->cover('Moo-2.23');
if (defined $cover->criteria) {
    $total =  $cover->criteria->{total};
}

[szabgab]

And if you would like to implement this you might want to wait till this is closed: metacpan/MetaCPAN-Client#114

Oh, that looks interesting. I think I read something recently about Coveralls.io going the way of Travis-CI and removing their free tier. It will be nice to have a replacement.

Two points though:

• Running this for my CPAN modules, I see that only about half of them have the data. Do you know why some releases have it and some don't?
• It would be good to be able to turn it into a real badge. Maybe I'll have a play on https://shields.io/ later.

[szabgab]

Are the ones missing the data old releases? Maybe ones that have non-perl requirements?

AFAIK The data comes from http://cpancover.com/ so @pjcj might shed some light on why some (many?) are missing the results and what could be done to improve that?

[davorg]

Actually, it might be the more recent releases that are missing data. I wonder how often cpancover runs.

That's wrong. The data is all over the place.

I'm not absolutely sure where all the data is coming from, but the first entry has coverage data on cpancover: http://cpancover.com/latest//App-Aphra-0.0.6/index.html so something seems wrong somewhere along the path.

For some modules cpancover doesn't have data, perhaps due to missing dependencies, the run taking too long, or bugs somewhere. You'll normally be able to get the full logs from the cpancover site as a gzipped text file to work out exactly (or roughly) what went wrong.

Newly uploaded modules are usually processed within some minutes, but it can be a few hours if lots of modules get uploaded together and especially if there are some releases which take a long time to run.

[davorg]

App::Aphra has some particularly gnarly prerequisites, so it's highly likely that its test run just failed. I'll dig a bit further into the others.

Update: But, of course, that didn't happen because cpancover has the results.

[szabgab]

@pjcj Where can we get those gzipped text files with the errors? I have never noticed them.

[pjcj]

The logs are behind the pilcrow sign which isn't immediately obvious I'm afraid unless you happen to be one of the first distributions on the page

Looking up what is a pilcrow...., oh I see. I completely missed that column. Thanks.
