Bug #1298
closed404 errors not processed properly
Description
I'm using v1.4.16 via the redhat spec file, and am having trouble with the way lighttpd is processing 404 errors.
I've set "server.error-handler-404 = "/clear.gif"" in the config file (chrooted), but when I make a non-existent file request, it sends the 404 image (clear.gif), but also appends it with its internal error message and sends a text/html content-type head.
Here's the output I get:
GIF89a??€??ÀÀÀ???!ù????,???????D?;<?xml version="1.0" encoding="iso-8859-1"?>

</head>
<body>
<h1>404 - Not Found</h1>
</body>
</html>
When running lighttpd with "debug.log-request-handling = "enable"", heres what I get in the logs:

Also to add, when the request is refreshed, the image data is not sent that time. Only on a new request.
So if I change the url to http://localhost/nofile it will show the image with the error appended, but only the error on a refresh. Now if I load http://localhost/nofile2 it will show the image with the error appended, but again with a refresh it will only show the 404 message.

Tested with 1.4.15 and the problem does not exist with that version.

Well after hours of debugging, I've found the problem.
The difference between 15 and 16 is a one line addition. Removing it has resolved the problem.

I've tracked it down to changeset r1853

This is a very serious bug. Amongst many other gotchas, it will break every rails installation using lighttpd unless they work around it with a cumbersome mod_magnet/lua solution (assuming they linked against lua at all), or just avoid upgrading lighttpd until it is fixed.
