Krinkle removed a project: PHP 7.0 support.Oct 12 2018, 6:45 PM

While we'll have to drop HHVM support soon, we're migrating to PHP 7 even sooner. So this isn't currently blocking PHP 7.0 support.

Per T176370, the initial production roll-out will likely use PHP 7.2, or maybe PHP 7.3 even (we're currently evaluating the viability of fast-tracking that and do the gradual roll-out straight from HHVM to PHP 7.3 for user traffic). More details and question at T176370, but it does mean we won't drop HHVM until after PHP 7.3 support is finalised.

Will this happen in 1.35?

Krinkle added a comment.Sep 24 2019, 4:50 PM

I think we're trying to make it happen as part of 1.34, might need to be backported at the last minute.

Even we don't make it, what will happen is that we drop support in documentation, but that it might (accidentally) work during the first .0 release, but we have no intention of supporting it officially. Once WMF has migrated away, all testing on master and REL1_34+ will cease, possibly for older branches as well (to be determined).

Huh, that soon? I thought we would deprecate HHVM support in 1.34, and remove it in 1.35.

Good, thanks. So, basically, we can update the docs and unblock these patches as soon as 1.34 is cut?

Krinkle added a comment.Sep 24 2019, 5:41 PM

Once HHVM is completely and disabled from WMF production servers relating to MediaWiki and e.g. 1-2 weeks have passed, then we can immediately remove support for it in master.

For documentation it is fine to already remove it. It has been stated for several releases already that HHVM only works for WMF and will be removed as soon as the migration is completed. We will not be supporting HHVM for the full 1.34 release cycle.

It was never really supported, and deprecated in 1.31. It's only dragged on for so long because of Wikimedia production.

No.

Drawing the line between "stuff that happens post-HHVM" and "stuff required for WMF to start using PHP7" at this task. It's useful to track al the things the migration unblocked, so I've re-added them as parent tasks here (sorry about the noise), and instead broke the link with T176370 in order to keep the tree somewhat sane.
