Invalid glyph requests block rendering

[fnicollet]

Hi,
I was trying an example that someone else on twitter created (@vtcraghead) but didn't get the same result. In my case, I have missing tiles:

What it should render:

What I get:

I am using Chrome 36 on Windows 8.1

If I look at the console, I have a few errors:

Image from origin 'https://www.mapbox.com' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://bl.ocks.org' is therefore not allowed access. 

XMLHttpRequest cannot load https://www.mapbox.com/mapbox-gl-styles/sprites/outdoors.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://bl.ocks.org' is therefore not allowed access. 

GET https://mapbox.s3.amazonaws.com/gl-glyphs-256/Open%20Sans%20Normal,%20Arial%20Unicode%20MS%20Bold/0-255.pbf 403 (Forbidden) 

Tell me if you need more informations

Looks like the failed glyph protobuf load is blocking rendering.

https://mapbox.s3.amazonaws.com/gl-glyphs-256/Open%20Sans%20Normal,%20Arial%20Unicode%20MS%20Bold/0-255.pbf

is an invalid path (no matching glyph protobuf exists there), although a failed request shouldn't block tile rendering...

Ref mapbox/mapbox-gl-native#308 for equivalent issue in mapbox-gl-native

Good call - I used the wrong typeface name. Now that it's fixed it's back to rendering smoothly. Though it would indeed be awesome to have it handle the error more elegantly.

thanks for reporting! 7fb6a3d now prevents bad glyph requests from killing the entire tile
