+[[!template id=gitbranch branch=smcv/unescaped-meta author="[[Simon_McVittie|smcv]]"]]
+[[!tag patch]]
+(Warning: this branch has not been tested thoroughly.)
+
+While discussing the [[plugins/meta]] plugin on IRC, Joey pointed out that
+it stores most meta fields unescaped, but 'title', 'guid' and 'description'
+are special-cased and stored escaped (with numeric XML/HTML entities). This
+is to avoid emitting markup in the `<title>` of a HTML page, or in an RSS/Atom
+feed, neither of which are subject to the [[plugins/htmlscrubber]].
+
+However, having the meta fields "partially escaped" like this is somewhat
+error-prone. Joey suggested that perhaps everything should be stored
+unescaped, and the escaping should be done on output; this branch
+implements that.
+
+Points of extra subtlety:
+
+* The title given to the [[plugins/search]] plugin was previously HTML;
+ now it's plain text, potentially containing markup characters. I suspect
+ that that's what Xapian wants anyway (which is why I didn't change it),
+ but I could be wrong...
+
+* Page descriptions in the HTML `<head>` were previously double-escaped:
+ the description was stored escaped with numeric entities, then that was
+ output with a second layer of escaping! In this branch, I just emit
+ the page description escaped once, as was presumably the intention.
+
+* It's safe to apply this change to a wiki and neglect to rebuild it
+ (assuming I implemented it correctly!), but until the wiki is rebuilt,
+ titles, descriptions and GUIDs for unchanged pages will appear
+ double-escaped on any page that inlines them in `quick=yes` mode, and
+ is rebuilt for some other reason. The failure mode is too much escaping
+ rather than too little, so it shouldn't be a security problem.
+
+* Reverting this change, if applied, is more dangerous; until the wiki is
+ rebuilt, any titles, descriptions and GUIDs on unchanged pages that
+ contained markup could appear unescaped on any page that inlines them
+ in `quick=yes` mode, and is rebuilt for some other reason. The failure
+ mode here would be too little escaping, i.e. cross-site scripting.

> And this is an illustration why a clean work-around (without changing the software) is not possible: while thinking about [[todo/matching_different_kinds_of_links]], I thought one could work around the problem by simply explicitly including the kind of the relation into the link target (like the tagbase in tags), and by having a separate page without the "tagbase" to link to when one wants simply to refer to the tag without tagging. But this won't work: one has to at least once refer to the real tag page if one wants to talk about it, and this reference will count as tagging (unwanted). --Ivan Z.
> But well, perhaps there is a workaround without introducing different kinds of links. One could modify the [[tag plugin|plugins/tag]] so that it adds 2 links to a page: for tagging -- `tagbase/TAG`, and for navigation -- `tagdescription/TAG` (displayed at the bottom). Then the `tagdescription/TAG` page would hold whatever list one wishes (with `tagged(TAG)` in the pagespec), and whenever one wants to merely refer to the tag, one should link to `tagdescription/TAG`--this link won't count as tagging. So, `tagbase/TAG` would become completely auxiliary (internal) link targets for ikiwiki, the users would edit or link to only `tagdescription/TAG`. --Ivan Z.
