[Wikitech-l] SOLVED Re: VisualEditor in 1.28 - fails after upgrade from 1.27

OK, I have traced the issue, and I'm embarrassed to say, it's in a custom extension. (I removed the extension yesterday and the error kept happening, so I figured the extension was harmless... but I'll bet I was fooled by browser caching.) Apologies if my incorrect information wasted anyone's time. The real issue is that a custom callback for the hook "SpecialPages_initList" is invoking RequestContext::getMain()->getUser()->isLoggedIn(). Apparently that doesn't work. I'll take a guess that SpecialPages_initList runs too early for this check to succeed? My goal is to remove some special pages for anonymous users but permit logged-in users to see them. Is there a better way to check for a logged-in user at this hook point? Or a better way to remove special pages for anonymous users? Thank you very much for any advice, DanB ________________________________ From: Daniel Barrett Sent: Monday, December 19, 2016 8:21 PM To: Wikimedia developers Subject: Re: [Wikitech-l] VisualEditor in 1.28 - fails after upgrade from 1.27 Sure. How do I get a full stack dump when the error appears only in the Chrome developer console? BadMethodCallException from line 845 of <...>/w/includes/session/SessionManager.php: Sessions are disabled for this entry point I've already enabled $wgShowExceptionDetails (which caused slightly more detail to appear, but no stack dump) and set every other debugging flag in sight on https://www.mediawiki.org/wiki/Manual:How_to_debug#PHP_errors in LocalSettings.php and in index.php. The only output I get is the above line in the Chrome developer console. The error does not appear in the associated Apache error log file.

Certainly not the first time I've seen it... On 19 Dec 2016 3:31 pm, "Brad Jorsch (Anomie)" &lt;bjorsch(a)wikimedia.org&gt; wrote:
