Hi,
https://gerrit.wikimedia.org/r/266931 has been merged, so MediaWiki core now requires PHP 5.5.9 or higher to run. We had to make some (read: a lot) of CI changes for that to happen, here's a quick summary:
* php53 jobs are only triggered for REL1_2[3-6] branches * php55 jobs are only triggered for branches that are not REL1_2[3-6] * All extensions that previously had php53 tests now run them under both hhvm and php55 * composer related jobs were renamed to standardize with other CI jobs
Since this is a large change for extensions, I went ahead and ran jobs for all extensions that have unittests, and collected the results: https://www.mediawiki.org/wiki/User:Legoktm/PHP_5.5/Extensions. Please take a look to see if your extension(s) are failing, and fix or file bugs as needed! Some of the failures aren't even related to HHVM/PHP5.5, the repos have just been broken.
And if you run into any CI related issues, please file a bug in the #CI-Config Phab project!
