Drush runserver HTTP server doesn't support callbacks with dot in the URL

[kenorb]

I've the following testing URLs (which exists in Drupal 7):

/taxonomy/autocomplete/foo_bar
/taxonomy/autocomplete/foo.bar

These Drupal URLs normally works in Apache by giving the error:

Taxonomy field foo.bar not found.

When testing using drush rs, the second URL doesn't work properly and it gives the following error:

Not Found

The requested resource /taxonomy/autocomplete/aa.00 was not found on this server.

Log entry:

[Tue Sep 29 15:56:11 2015] 127.0.0.1:54729 [404]: /pca/retrievebyid/25764183.00 - No such file or directory

I've found this when implementing PCA and this callback.

So my local menu callback (pca/retrievebyid/1234.00) doesn't accepts the Id argument, because it's never gets passed into Drupal, as it consist dot (.). So for some reason drush is giving 404 page.

The easiest way to reproduce the problem is by running: drush qd.

I'm using drush rs for testing purposes.

I believe the error is could be somewhere in runserver_parse_uri(), but I'm not sure exactly how the URLs are handled.

The issue that paths containing a dot aren't working is because the built-in php server assumes that all files containing a dot are an file in the filesystem. If a router script is passed to php -S then this behavior is bypassed and the all the urls start working.

I think this can be fixed by using the d8-rs-router.php for drupal 7

It also fails for Advanced Help module which scans for the help files and generates the appropriate callbacks.

So going into: /help/commerce_paypoint_advanced/README.md
generates Not Found page as well.

The solution is to start the server in docroot as:

php -S localhost:8888 .ht.router.php

Where .ht.router.php file can be found at: Add a startup configuration for the built-in PHP server that supports clean URLs

For drush use d8-rs-router.php/rs-router.php found in commands/runserver.

Works for both Drupal 7 & 8.
