URL: https://en.wikipedia.org/w/api.php?action=query&meta=siteinfo&siprop=specialpagealiases&format=xmlfm Current response: <?xml version="1.0"?> <api servedby="srv214"> <error code="internal_api_error_MWException" info="Exception Caught: Internal error in ApiResult::setIndexedTagName: Bad parameter" xml:space="preserve" /> </api> Seems related to the format parameter (specifically XML). &format=json and &format=jsonfm both work fine. Discovered by Fran McCrory.
Works in 1.20wmf6, Fails in 1.20wmf7
Caused by Gerrit change #9865
Reverted in https://gerrit.wikimedia.org/r/#/c/15903/ and to wmf7 in https://gerrit.wikimedia.org/r/15904
The problem was that some special pages don't have aliases. Correct fix in https://gerrit.wikimedia.org/r/16001.
