Closed, ResolvedPublic


Why is it so slow? What can we do to try and speed it up? I'll bump up the limit again in the meantime.

On my local computer (stretch/php7):

phunit8 seconds
phpunit --coverage-html6 minutes

On my laptop with php 7.1 it hits the memory limit around 66% and dies. But let's give PHP 7 a shot! I can't think of any reason why it would be worse.

Change 386679 had a related patch set uploaded (by Legoktm; owner: Legoktm):
[integration/config@master] Run RemexHtml coverage on PHP 7

The php-code-coverage library with PHPUnit 4 is also quite old. I found that when trying for MediaWiki core, switching from PHPUnit 4 to 5 or 6 made a much bigger difference than the PHP upgrade. Although, naturally, this is blocked on raising the PHP requirement... :) But perhaps you can swap out the PHPUnit library, just for the coverage job? That's what I did for mediawiki-core-coverage as well during the experiment.

@Legoktm RemexHtml now shows up on Was that a local change on Jenkins, or did it get resolved differently - without landing

Sorry, I deployed a change via jjb to test it and never followed-up. I was trying to figure out the difference in the reporting between PHP 5.5/5.6 coverage and PHP 7.0 coverage (T147778) before progressing further.

Change 386679 abandoned by Krinkle:
Run RemexHtml coverage on PHP 7
