Bug ID: 66505
Summary: Flow Parsoid/Utils.php exceptions:
"htmlParseEntityRef: no name" in createDom() for
RedLInker
Product: MediaWiki extensions
Version: master
Hardware: All
OS: All
Status: NEW
Severity: normal

In exception.log we're getting a dozen or so exceptions a day from
Parsoid/Utils.php complaining about "htmlParseEntityRef: no name" when it tries
to createDOM()
I think most or all of the calls are from Parsoid/Redlinker->apply() . The
exception originates from various URLs: ?action=history on a Flow board,
Special:Watchlist, Special:RecentChanges, also Special:RecentChangesLinked.
What's confusing me is:
a) Some of these URLs are not even Flow boards, e.g. the following log entry is
from
https://www.mediawiki.org/wiki/Special:RecentChangesLinked/Wikimedia_engineering_report/2013/December/summary
Visiting this link generates an exception every time.
b) Do we need to parse redlinks when generating formatter lines?
I don't think any of these manifest something visible to the user, I guess the
change line with the exception is skipped.
Sample exception.log entry follows. Many of the 115 or so exceptions in May and
June have this stack trace
