I missed the creation of this ticket, my comment from the other once applies:

installdbs in the mediawiki-docker-dev setup does install.php and then update.php

quibble does install.php with the --with-extensions parameter.

I remember there being some issues with some extensions and --with-extensions for install.php before, so I imagine this is something similar.

From another ticket:

In T196173#4252779, @Legoktm wrote:

The installer explicitly does not load the full extension during the install process. This means the extension has been broken with the web installer for quite a while now :( (also this is not ideal, but it's the rather fragile status quo, that hopefully we can move away from soon)

Other extensions that got hit by the same thing are:

• T198331: [Cognate] install fails with BadMethodCallException from line 83 of includes/libs/rdbms/lbfactory/LBFactorySingle.php: Method is not supported.
• T198330: [GlobalPreferences] install fails with MultiConfig::get: undefined option: 'GlobalPreferencesDB'

Quoting @hashar on IRC:

the workaround is to have the extension to set sane defaults internally

In Math the problem code is the optional creation of DB tables based on this configuration:

		if ( in_array( 'latexml', MathRenderer::getValidModes() ) ) {
			if ( in_array( $type, [ 'mysql', 'sqlite', 'postgres' ] ) ) {
				$sql = __DIR__ . '/../db/mathlatexml.' . $type . '.sql';
				$updater->addExtensionTable( 'mathlatexml', $sql );
				if ( $type == 'mysql' ) {
					$sql = __DIR__ . '/../db/patches/mathlatexml.mathml-length-adjustment.mysql.sql';
					$updater->modifyExtensionField( 'mathlatexml', 'math_mathml', $sql );
				}
			} else {
				throw new Exception( "Math extension does not currently support $type database for LaTeXML." );
			}
		}
		if ( in_array( 'mathml', MathRenderer::getValidModes() ) ) {
			if ( in_array( $type, [ 'mysql', 'sqlite', 'postgres' ] ) ) {
				$sql = __DIR__ . '/../db/mathoid.' . $type . '.sql';
				$updater->addExtensionTable( 'mathoid', $sql );
				if ( $type == 'mysql' ) {
					$sql = __DIR__ . '/../db/patches/mathoid.add_png.mysql.sql';
					$updater->addExtensionField( 'mathoid', 'math_png', $sql );
				}
			} else {
				throw new Exception( "Math extension does not currently support $type database for Mathoid." );
			}
		}

Perhaps the extension should instead just always create all tables.

Hi @Physikerwelt,
I'd be curious to see if T202223 is resolved if this is overcome. There has to be a hook combination to make sure the code setting the valid modes (in the global if need be) is invoked before trying the db setup.

@Pablo-WMDE no it's not. I'm a bit frustrated that I blocks me from doing anything. I don't understand how a change in Wikibase can affect the Math extension configuration. I suspected that the problem is the use of globals, but it did not help as well. Is there a way one can debug or reproduce the new unit testing environment?

I don't think this really has anything to do with Wikibase.
I believe this is because the CI used to not run quibble and now it does.

June 27 https://gerrit.wikimedia.org/r/#/c/mediawiki/extensions/Math/+/441508/ ran the mwext-testextension-hhvm-jessie job and passed
7th July it was migrated to quibble https://github.com/wikimedia/integration-config/commit/3275fdb5b29f90bbf9d8dbeea5acdfd2d2bedb12#diff-48f8c0f4652ffe6e8964cb497ef6cc88
I'll tag T183512 and @hashar

Maybe this one slipped through broken?

Hi @Physikerwelt,

how a change in Wikibase can affect the Math extension configuration

As I understand it this is not the case in this situation. We both build extensions that are integrated by the CI system using their patch/latest version. The Math extension configuration seems to be partially incompatible with the CI system (now that it changed). Unfortunately it is not breaking right where this happens (this could improve) but keeps on going a bit further. The place where this finally is surfaced is in a Wikibase(Lexeme) test, but the root cause is in the configuration. Let's see if the tests are green when the warnings from the setup phase are gone.
