[Regression] MWException when saving section=new on .css and .js pages
Closed, ResolvedPublic

Description

To reproduce:

  1. Open a css page for editing with section=new, e.g. http://en.wikipedia.org/wiki/Special:MyPage/common.css?action=edit&section=new
  2. Enter text.
  3. Click "Save page".

Ideally the initial action=edit&section=new should present an error message. At the least, the attempted save should present an error message instead of throwing an uncaught exception.

Exception:

Adding sections to JS/CSS pages doesn't make sense and will not be supported.
But there should be no fatal error, this should be handled more nicely.

But there should be no fatal error, this should be handled more nicely.

Exactly.

Change I3d2901b7: (bug 43008) show error page if sections not supporte.

  • Bug 43784 has been marked as a duplicate of this bug. ***

for the reasons mentioned in Bug 43784, it makes sense for me.

This should no longer be an *internal* error, but a "normal" user level error. Which it currently is, as far as I can see.

I maintain that adding sections to JavaScript makes no sense and is misleading. Section support needs more than just adding sections, it also needs a way to split a text by section, etc. This would horribly break JS.

The use case described by bug 43784 is a nasty hack, if you want a nice interface for appending to page text, file a feature request for that.

I'll not close this now, so to not start an edit war. I suggest however to again close this as fixed, especially since the original problem, the fatal error, is gone. What is left is a request to restore the ability to somehow append to JavaScript. That should be a separate bug.

I'll close it again. For the reasons above, if you want an interface to append arbitrary text to any page, even pages that don't support sections, open a new bug.
