#49851 [Opn]: http wrapper breaks on 1024 char long headers

ID: 49851 Updated by: jani@php.net -Summary: HTTP breaks on long header line Reported By: sjoerd-php at linuxonly dot nl Status: Open -Bug Type: HTTP related +Bug Type: Streams related Operating System: * PHP Version: 5.*, 6 New Comment: So it's a bug in streams code (http) and not server side. Your summary for this bug report sucks and the category was wrong. And I should read all comments. :) Previous Comments: ------------------------------------------------------------------------ [2009-12-02 16:53:11] sjoerd@php.net Apache module. The important thing is that a.php gives a header which is exactly 1024 bytes long, including \r\n. The file_get_contents than gives a wrong result, and you can run that on the CLI or any other SAPI. ------------------------------------------------------------------------ [2009-11-30 19:48:27] jani@php.net What SAPI are you using? I can not reproduce this with fastcgi + lighttpd.. ------------------------------------------------------------------------ [2009-10-24 08:08:10] sjoerd@php.net Thank you for your input. However, I disagree with your post. > php internally does not have any hard coded limit http_fopen_wrapper.c:75 #define HTTP_HEADER_BLOCK_SIZE 1024 > the header does not end with \r\n This is not needed with header(). > $string = str_pad('X-Padding: ', 1022, 'x').'\r\n'; This appends \r\n instead of CRLF, because you use single quotes instead of double quotes. ------------------------------------------------------------------------ [2009-10-24 02:16:58] srinatar@php.net php internally does not have any hard coded limit to parse the header value. the only time, you will see http header in your output is when the header does not end with \r\n (to mark it as new line). as per HTTP spec, every HTTP headers need to end with \r\n (CR LF) to mark the end of the line. php internally checks for this line to determine if the header is done before proceeding to parse the body of the request. if you modify this below test case to reflect that there needs to be \r\n to mark it as end of line, then you will see the expected output. <?php $string = str_pad('X-Padding: ', 1022, 'x').'\r\n'; header($string); header('Location: http://www.google.nl/'); echo "Foo"; ?> i suggest marking this bug as bogus (or not an issue). ------------------------------------------------------------------------ [2009-10-12 21:16:11] lbarnaud@php.net Verified, since 5.1.0 at least. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
