Add integration test to ensure that uninstalling CDN module causes filtered text to have non-CDN URLs

both stable and dev.

There is no stable release yet.

Looks like your CSS is not loading. Can you post a screenshot of the web developer tools showing your requests, and a screenshot of a CSS request in particular?

I excluded .css and .js for being served by MAXCDN

What does this mean? Did you do this exclusion thing on the Drupal side or on the MaxCDN side?

Instead i tried to serve an Image.

I'm assuming this is what you tried to show in the screenshot https://www.drupal.org/files/issues/Screen%20Shot%202016-08-29%20at%2017... ? If so, that looks to be working?

Please export and upload your cdn.settings configuration.

And it’s not working since instead of the jpg it displays a placeholder with the message> “the image was removed. for security reasons only images from the local domain are allowed”…

Oh, I see. That is \Drupal\filter\Plugin\Filter\FilterHtmlImageSecure interfering. That's absolutely a valid bug report! Thanks :)

Problem or not problem, support or not support, the fact is that the css/js/jpg files are blocked when served from MAXCDN…

I still don't understand this. Can you open a separate issue for this?

The screenshot you posted indicates SSL certificate issues. Contact MaxCDN support about that.

I have a big question. When i deactivated (uninstalled+removed from server) the module about one hour ago to change between available versions, i observed that the image from the test-article was still linked to MAX CDN.

Oh, right, in D8 module (un)installation no longer clears all caches. So I'll need to make sure that the cache is invalidated. Updated the issue summary to reflect that.

I'll try to address these problems this weekend.

Thank you very much for reporting these problems! :)

I worked on this part: CDN + filtered text: FilterHtmlImageSecure considers images served from a CDN to be insecure. But I can't reproduce it. basic_html has the correct configuration:

…
  filter_html_image_secure:
    id: filter_html_image_secure
    provider: filter
    status: true
    weight: 9
    settings: {  }
  editor_file_reference:
    id: editor_file_reference
    provider: editor
    status: true
    weight: 11
    settings: {  }

Note how filter_html_image_secure has weight 9 and editor_file_reference has weight 11. This means editor_file_reference will always run after filter_html_image_secure. And it's in <code>editor_file_reference that the file URL is generated that will point to the CDN.

The only possible conclusion is that your text format has the filters in the wrong order. Can you export your text format at /admin/config/development/configuration/single/export and post it here?

I've now finished writing the test coverage for Uninstalling CDN module continues to serve cached filtered text. I can't reproduce that either, nor can the test.

And now converted from WebTestBase to BrowserTestBase.

Hm, it passes locally. Probably subdirectory-related.

That was it :)
