runserver: 404 when dot character in clean URL path

[GarrettAlbright]

When using runserver, I noticed I was getting a PHP error from the server (not from Drupal) when attempting to go to a Memcache server report page with a path that looks like http://127.0.0.1:8888/admin/reports/memcache/default/127.0.0.1%3A11211 (%3A is an encoded colon character).

However, if I manually adjust the path to make it "dirty," like http://127.0.0.1:8888/index.php?q=admin/reports/memcache/default/127.0.0.1%3A11211, it works just fine.

I thought this might be an issue in runserver-prepend.php, but after some consternation, as far as I can tell, that file doesn't even execute whenever there's a period in the clean path. I can only assume that PHP is assuming that there's a file involved whenever it sees a dot in the path, looking for that file, then failing when it can't find it without giving the prepend file a chance to have a say in the matter.

I notice that we don't seem to be using a router file. Would it be possible to avoid this problem if we had one? I'm not sure.

I'm seeing the same, and it looks like this is the expected default behavior with PHP's built-in server:

Using a router file does mitigate the issue however, and the included D8 one seems to work just fine. I don't know enough about the history of the runserver-prepend file to determine if it's still necessary for D7, but the router file seems like the right approach moving forward.

Got fixed by #2033 AFAIK

For D7, see #1658
