I'm not a PHP person, but if I put this in a test file and run it in the same way, it works. Not sure what it is about the update script that causes it to fail.

I just ran into this today upgrading 1.42 to 1.43

I run a private wiki, and this is quite a pain point.

Hello! As a wiki administrator, how do I ensure I've updated to the patched version?

I have not migrated the database yet, could this be the issue?

Which documentation do you follow for upgrading?

@dbarratt I edited the post to add links to related issues. Here is the issue for php.ini https://phabricator.wikimedia.org/T272406#6759012

I'm not a MediaWiki expert, I'm just talking from my experience installing a new wiki.

Hello. Is there any documentation on how to use this image?

I set

No luck. It seems that it's using $wgServer (looking into if I can get more detailed console logging).

I've worked it out - it was because the hostname visible from the server was different to the public hostname that was set in $wgServer.

I don't think it's clear, due to the 5 points above + Lonaowna 's comments. There's a lot of conflicting/confusing info between the various sources. It's maintained by docker but the source and bug tracker are in WikiMedia's Github org, Docker says it's official but WikiMedia says it's not, except in the readme hosted in WikiMedia's repository that says it is.

The upstream image I was talking about: https://hub.docker.com/_/php/ that is quoted in the original post.

Sorry for being unclear, I hope I posted in the right place!

I also read the message on MediaWiki.

I also ran into this and the solution was the same: the hostname needs to be the name of the docker host when running with docker-compose. I'd submit a PR, but the error is on Docker Hub, and I don't see an obvious way to edit that.
