Disallow dynamic property access on ParserOutput
Open, Needs TriagePublic
Actions

Description

Per mediawiki 1.20 the way for extensions to attach custom data to the ParserOutput was to declare a dynamic property. Now the mechanism exists, ParserOutput::getExtensionData/setExtensionData to do this properly.

We need to find all the places in the deployed extensions where dynamic property access is still happening, replace usages with a fallback on __get, wait for ParserCache expiration period, drop support for it and trigger an error if an attempt is made to use dynamic properties on ParserOutput.

It seems like a good way of tracking the usages of this is by grepping for PhanUndeclaredProperty suppression.

• Pchelolo changed the task status from Open to Stalled.Sep 25 2020, 6:19 PM

Ok, now nothing in the deployed extensions or core writes to the dynamic properties in the ParserOutput, however LiquidThreads and ProofreadPage still fallback to the property since it could be coming from the ParserCache.

Now we need to wait for at least 1 month before removing the fallbacks to make sure ParserCache has expired, after that drop the last two fallbacks and either start emitting the deprecate warning or throwing an error if the dynamic property is accessed.

SemanticMediaWiki also uses dynamic properties. We started getting a bunch of logspam in translatewiki.net yesterday after we updated to get the security fixes. We had to revert the patch locally.

With the latest latest version, with partially removed deprecation, you should not be getting logspam for dynamic properties, only direct access to static properties.

I can fix SemanticMediawiki as well.

Blocking until ParserCache has expired and we can drop fallbacks in remaining extensions.

Thanks! We will test this on Wednesday.

@Nikerabbit Also, the semantic mediawiki PR above should fix it on their side. If you see some more logspam, please save it somewhere, I'd go through it and fix all issues
