Problem/Motivation

We have a site with over 60 languages, many using non-ascii chars in their paths. Any path using non-ascii chars causes an error when we try to purge

Steps to reproduce

Create some content with non ascii path , etc 'hostname.com/stories/пицца'

Paste 'stories/пицца' into the 'Paths/URLs/CPCodes' text box

You'll get an error "There was an error clearing the cache. Check logs for further detail."

Looking at logs you'll see:

  1. So my initial question here is if you supply Akamai an encoded URL, does it properly invalidate the cache for the non-encoded version of the URL? In theory I'm fine with changing it, but I'm unsure if it is actually useful if it's trying to invalidate cache for a different URL than what you actually want. Have you been able to verify this on the Akamai side? 
  2. @@ -325,6 +325,10 @@ abstract class AkamaiClientBase extends PluginBase implements AkamaiClientInterf
     foreach ($urls as &$url) {
       $url = $this->normalizeUrl($url);
     }
+    // Urlencode non-ascii chars.
+    $url = preg_replace_callback('/[^\x20-\x7f]/', function ($match) {
+      return urlencode($match[0]);
+    }, $url);
     return $urls;
   }

    This solution doesn't seem correct to me. You are replacing the $url value, not inside the loop, but after the loop is done where $url is ever getting used. In best case, it will only update that last url in the list (although I'm admittedly unsure about variable scope when using & references, so I'm not sure if it will even do that off the top of my head).

    Additionally this only ever impacts ::normalizeUrls(), but there are some other cases where ::normalizeUrl() (without the trailing "s") is used (e.g., CacheControlForm::submitForm()), and it doesn't seem to resolve the issue there either. I think it would be better if this normalization occurred in ::normalizeUrl() instead.

  3. I'd definitely want to see some test coverage added to ensure this is all wired up correctly
