When the script filename is just /index.php, dirname() returns '/' for it. In Request::prepareBaseUrl() we append '/' to it (as introduced in #13039), which is wrong in this scenario as the resulting string is '//'.
When we rtrim('/') the output of dirname() then '/' would be constructed in this case, and in all other cases it makes no difference as dirname() already trims the right forward slash if there are path segments.
The test-cases should clarify the exact scenario.

[HttpFoundation] [Request] fix baseUrl parsing to fix wrong path_info
Hi everyone!
We at trivago had an issue with the Request object. It seems that all versions of symfony 2.x and 3.x are affected from this (possible) bug (don't checked 1.x).
Here is the problem:
some old legacy pages are deployed in the Document Root, let's say /var/www/www.test.com/ .
one or more new applications based on symfony are deployed to /var/release/new_app1/ , /var/release/new_app2/ , ... .
in /var/www/www.test.com/ there is a symlink "app" to /var/release/new_app1/web, like:
/var/www/www.test.com/app --> /var/release/new_app1/web/
there is a "SEO"/human-readable rewrite rule for Document Root (if called path/file not exist): (.*) --> app/app.php
the problem comes, when the user calls a uri starting with "app" or whatever the rewrite rule / symlink points to:
the user calls "http://www.test.com/apparthotel-1234"
results in $_SERVER parameters like this
```
'DOCUMENT_ROOT' =>'/var/www/www.test.com',
'SCRIPT_FILENAME' => '/var/www/www.test.com/app/app.php',
'SCRIPT_NAME' => '/app/app.php',
'PHP_SELF' => '/app/app.php/apparthotel-1234'
```
in Request::prepareBaseUrl() there are checks to find the baseUrl:
```
if ($baseUrl && false !== $prefix = $this->getUrlencodedPrefix($requestUri, $baseUrl)) {
// full $baseUrl matches
return $prefix;
}
if ($baseUrl && false !== $prefix = $this->getUrlencodedPrefix($requestUri, dirname($baseUrl))) {
// directory portion of $baseUrl matches
return rtrim($prefix, '/');
}
```
first it is checked if (in our case) "/app/app.php" is in the request uri (/apparthotel-1234).
it's not.
then it takes the dirname (of /app/app.php) which is /app and checks if it is in the request uri (/apparthotel-1234), and YES, it is! and "/app" is returned, but this is wrong, it should be empty (because it comes from a rewrite rule from root: /)!
later in preparePathInfo(), if there is a baseUrl, then the baseUrl is removed from the request uri:
/apparthotel-1234 ---> /arthotel-1234
The cause is, the second baseUrl check, checks if the path of the application is already in the uri, like when the request was "http://www.test.com/app/apparthotel-1234" and hit a rewrite rule like (.*) --> app.php in there, but because it matches a directory it must match "dirname($baseUrl) . '/'".
I also needed to fix one unit test of the getBaseUrl test:
the request uri recently was "/foo%20bar".
but from the $_SERVER infos "foo bar" is a directory, see:
```
'SCRIPT_FILENAME' => '/home/John Doe/public_html/foo bar/app.php',
'SCRIPT_NAME' => '/foo bar/app.php',
'PHP_SELF' => '/foo bar/app.php',
```
webservers will redirect a request "http://www.test.com/foo%20bar" to "http://www.test.com/foo%20bar/" when "foo bar" is a directory. checked this for apache 2.x and nginx 1.4.x.
this fix is for symfony master (3.0.x, see #13039).
I also prepared a merge request for actual 2.7 branch, it will also follow in some minutes. (see #13040)
