The first broken build was on March 20th 2019 at 20:59:13 which is before that Gerrit change :/

hashar added a comment.Mar 21 2019, 10:11 AM

So it is broken and I have no idea what is going on sorry :(

hashar added a comment.Mar 21 2019, 10:26 AM

Wondering if that would cause the train to break when we next regenerate the l10n messages? T206676: 1.33.0-wmf.22 deployment blockers

$wmgFundraisingTranslateWorkflow is only enabled on meta. What I guess is happening is that maintenance/mergeMessageFileList.php loads extensions from wmf-config/extension-list.json in the order listed to the file. The script does roughly:

maintenance/mergeMessageFileList.php
        # Add setup files contained in file passed to --list-file
        if ( $this->hasOption( 'list-file' ) ) {
            $extensionPaths = $this->readFile( $this->getOption( 'list-file' ) );
            $mmfl['setupFiles'] = array_merge( $mmfl['setupFiles'], $extensionPaths );
        }

foreach ( $mmfl['setupFiles'] as $fileName ) {
    // Using extension.json or skin.json
    if ( substr( $fileName, -strlen( '.json' ) ) === '.json' ) {
        $queue[$fileName] = 1;
    } else {
        require_once $fileName;
    }

if ( $queue ) { 
    $registry = new ExtensionRegistry();
    $data = $registry->readFromQueue( $queue );
    foreach ( [ 'wgExtensionMessagesFiles', 'wgMessagesDirs' ] as $var ) {
        if ( isset( $data['globals'][$var] ) ) {
            $GLOBALS[$var] = array_merge( $data['globals'][$var], $GLOBALS[$var] );
        }
    }
}

Since extensions are listed in alphabetical order, the FundraisingTranslateWorkflow extension is passed to ExtensionRegistry->readFromQueue() before Translate and bails out. The extension has:

mediawiki/extensions/FundraisingTranslateWorkflow/extension.json
{
    "requires": {
        "extensions": {
            "Translate": "*"
        }
    }
}

Introduced by https://gerrit.wikimedia.org/r/#/c/mediawiki/extensions/FundraisingTranslateWorkflow/+/486345/ and committed on Wed Mar 20 20:42:53 2019 +0000.

Note that Translate has not been migrated to extension registry yet. Thus we extension-list has:

wmf-config/extension-list
IP/extensions/FundraisingTranslateWorkflow/extension.json
$IP/extensions/Translate/Translate.php

I would assume extension registry to hold a bit before enforcing the Translate requirement, but maybe the lack of extension.json in Translate causes extension registry to not know about it?

That is all I have for now. Require assistance from someone more knowledgeable about the registry mecanism :-(

A very basic attempt at reproducing the issue on my local setup:

$ php maintenance/shell.php
>>> require_once 'extensions/Translate/Translate.php';
=> 1
>>> $registry = new ExtensionRegistry();
=> ExtensionRegistry {#1082}
>>> $queue = [ 'extensions/FundraisingTranslateWorkflow/extension.json' => 1 ];
=> [
     "extensions/FundraisingTranslateWorkflow/extension.json" => 1,
   ]
>>> $registry->readFromQueue( $queue );
ExtensionDependencyError with message 'FundraisingTranslateWorkflow requires Translate to be installed.
>>> $registry->isLoaded( 'Translate' );
=> false
>>>

Oh, yeah, you can't use proper dependencies for extensions that haven't migrated yet. One moment, I'll write you a patch.
