Subramanya Sastry fb27cd0b4a Handle multiply-referenced ref-tags without duplicate ref-content. ... * When named-ref-tags are used multiple times in a document, the Cite.onReferences function was outputting the ref-content once for each use in the references section. While this is "harmless" for regular ref-content, when the ref-content has templates (ex: {[cite .. }}), that template content is duplicated several times -- this also means that template expansions seen in the output no longer has unique ids. Occasionally, this trips up DOM passes (template encapsulation) which make the reasonable assumption that template ids are unique. It introduced an infinite loop in the code that detects template range nestings and overlaps. This is not triggered always, but only in certain scenarios. en:Euphoria (Enrique Iglesias album) was a page that sent the parser into an infinite loop. * Now fixed by outputting ref-content once. * In addition, added an error-check in the DOM post-pass that might get stuck in an infinite loop to output an error message. * No change in parser test results. * en:Euphoria (Enrique Iglesias album) now parses and rts without getting stuck in an infinite loop. Possibly other pages as well. Change-Id: I81a055999eefe3ca36dfb8a9cda3fee538ae6c65		2013-02-20 17:50:52 -06:00
