The mediawiki-extensions-hhvm job (which is triggered by multiple repositories) has been broken because the SpamBlacklist extension points by default to meta.wikimedia.org which was unreachable (T89052). The extension has a default configuration:
```
lang=json,name=extension.json
"config": {
"BlacklistSettings": {
"value": {
"spam": {
"files": [
"https://meta.wikimedia.org/w/index.php?title=Spam_blacklist&action=raw&sb_ver=1"
]
}
},
"merge_strategy": "array_plus_2d"
},
"LogSpamBlacklistHits": {
"value": false
}
},
```
In a test context, the SpamBlacklist extension would want to set `$wgBlacklistSettings = array();`. We once wanted to find a way to provide test specific settings (via T89096) but never found a good solution. The status quo is to have the extension to provide sane default settings.
Wikimedia production has:
```
name=wmf-config/CommonSettings.php,lang=php
if ( $wmgUseSpamBlacklist ) {
wfLoadExtension( 'SpamBlacklist' );
$wgBlacklistSettings = [
'email' => [
'files' => [
'https://meta.wikimedia.org/w/index.php?title=Email_blacklist&action=raw&sb_ver=1'
],
],
'spam' => [
'files' => [
'https://meta.wikimedia.org/w/index.php?title=Spam_blacklist&action=raw&sb_ver=1'
],
],
];
$wgLogSpamBlacklistHits = true;
}
```
Tentatively we can make the SpamBlacklist extension to stop providing a default, but we would need to update documentation so that people installing the extension add it back (or their own).
