The Wikimedia Foundation has been employing HHVM to run MediaWiki in production since 2014.[1] Since then, a few things happened that made it compelling for us to move back to the "official" PHP interpreter:

  • PHP 7.x has brought huge performance improvements, so that its performance is nowadays comparable to, if not better than, HHVM for our needs.[2][3]
  • HHVM has dropped support for pure PHP in favour of Hack, an "evolution" of PHP which does not have widespread support.[4]

The Wikimedia Foundation is moving all Wikimedia wikis to use PHP7 in 2019.[5]

PHP7 जनवरी 2019 से उपलब्ध होगा।

[6]

Replacing the Beta Feature, since March 2019 a percentage of all production traffic has been randomly assigned to use PHP instead of HHVM.

You can verify that it is enabled for you by visiting Special:Version on your wiki, and checking that it says "php" instead of "HHVM" in the "Installed software" table.

प्रश्न और उत्तर

I am a non-technical user. What does this mean?

Hopefully nothing. This is about changing the software used to run the wiki's code. Ideally, you should notice no real difference.

यह कब होगा?

काम 2017 में शुरू हुआ, 2018 से अधिक समय तक चला, और 2019 की पहली छमाही में उत्पादन-पूर्ण होना चाहिए।

अगर मुझे कोई मुद्दा मिल जाए तो मुझे क्या करना चाहिए?

Report it on Phabricator, in the PHP 7.2 support project.

संपादन क्यों टैग किए जा रहे हैं?

This will help us identify performance, functional, and stability concerns specific to PHP in comparison to HHVM. You can ignore the PHP7 tags.
