Bug 232386 – REGRESSION(r284521) [GTK][WPE] many tests report parse errors as a result of the test files being interpreted as XHTML rather than HTML

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: New Bugs

[Arcady Goldmints-Orlov]

As a result of the change in r284521, numerous test files have started getting loaded as XHTML rather than HTML and the results of those tests end up being just a parse error message.

[Michael Catanzaro]

Of course, since r284521 was just a straight revert of r276635, I would expect the test expectations to go back to what they were prior to r276635.

The *correct* behavior would be "match whatever Safari does," but I suspect we never did. My recommended solution, from bug #230797:

"""
Of course, it would be *better* for WebKit to make content type decisions based on the DOCTYPE instead, but we can't expect a content sniffer to do that. We would have to implement it ourselves in WebKit, rather than farming out the work to GIO. I wonder how other ports handle this.
"""

This is what Bastien has recommended, as well.

Maybe the shared-mime-info version upgrade is related? I didn't revert the shared-mime-info version upgrade. The addition of new parse errors could mean shared-mime-info is just doing a better job of detecting XHTML than it was before.

I gardened some of the failures in r284936, and I am going to take a look at what happens if I revert the shared-mime-info change as well.

The shared-mime-info was bumped from 1.10 to 2.1 in r276635. Among other changes:

1.13:
* Prefer text/html to XHTML for *.html files
* Better magic for text/html files
* Fix SVG magic for files embedded in HTML

1.15:
* Fix some HTML files being detected as XML

We currently have two different bugs for this issue. This one is older, but I think there's a little more useful discussion in the other bug, so let's keep that one instead.
