Wiki names not case sensitive on windows server

[lucas]

When using the mod_rewrite option, new pages are not stored case sensitive, which makes a new pasge NewPage appear as newpage. The problem is in the .htaccess:

<IfModule mod_rewrite.c>
 RewriteEngine on
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^(.*/[^\./]*[^/])$ $1/
 RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L]
</IfModule>

The REQUEST_FILENAME contains only lower case characters on a windows machine. I don't know the solution though.

This only happen on windows machine. This problem cannot be solved in .htaccess, because it is not a syntax bug but an (I suppose) implementation bug of mod_rewrite on Windows. Here is how I fixed that:

if (preg_match("#^(.+?)/(.*)$#", $wakka, $matches)) list(, $page, $method) = $matches;
else if (preg_match("#^(.*)$#", $wakka, $matches)) list(, $page) = $matches;
if ($method)
{
 $method = preg_replace('/\..*$/', '', $method);
}
#Fix lowercase mod_rewrite bug: Url rewritting lowercases the page name.
if (strtolower($page) == $page)
{
 $pattern = preg_quote($page, '/');
 if (preg_match("/($pattern)/i", urldecode($_SERVER['REQUEST_URI']), $match_url))
 {
  $page = $match_url[1];
 }
}

I have XAMPP for Windows Version 1.7.2 that uses Apache 2.2.12. I am trying to test this out but it doesn't come as valid.

This is the procedure: wikka.php

<?php var_dump($_GET) ?>

.htaccess

<IfModule mod_rewrite.c>

RewriteEngine on

RewriteCond %{QUERY_STRING} vardump=1
RewriteRule ^(.*)$ wikka.php?the_request=%{THE_REQUEST}&http_host=%{HTTP_HOST}&request_filename=%{REQUEST_FILENAME}&query_string=%{QUERY_STRING} [QSA]

</IfModule>

Calling the url http://localhost/dev/Test/wikka.php?This=GOOD&vardump=1 this is the result:

array
  'the_request' => string 'GET /dev/Test/wikka.php?This=GOOD' (length=33)
  'vardump' => string '1' (length=1)
  'http_host' => string 'localhost' (length=9)
  'request_filename' => string 'E:/remote/dev/Test/wikka.php' (length=28)
  'query_string' => string 'This=GOOD' (length=9)
  'This' => string 'GOOD' (length=4)

So there is no change of case witnessed.

George, this ticket is a closed one. It was a valid bug, I've personally tested it on my Windows machine. Now it's been fixed by changeset 46. The fact that you didn't notice it in your environment doesn't mean it's an invalid bug.

I was searching the code to find optimizations that can be applied. This issue struck me as really odd and I decided to do some testing, since it came up 4 years ago.

Then I just reported the results. I am not trying to dig this from the dead, trust me. :)

It would be interesting to see if this kind of behavior still occurs in other environments. If you intend to research this further please use the same methodology as above so that we can compare the results.
