Bug #55010 [NEW]: POST requests send 4 extra bytes

From: Operating system: Ubuntu 11.04 PHP version: 5.3.6 Package: HTTP related Bug Type: Bug Bug description:POST requests send 4 extra bytes Description: ------------ PHP sends 4 extra bytes with a POST request when using stream_context_create and file_get_contents. The extra bytes are CR LF CR LF. The RFC does not state that CR LF CR LF should be after message-body. This appears to be the same as Bug #43222: stream_context_create() bugs Was there a test created to detect this problem? Test script: --------------- $url = 'http://localhost:8001/post'; $post = 'Sample'; // 6 bytes $options = array( 'http' => array( 'method' => 'POST', 'protocol_version' => '1.1', 'content' => $post, ) ); $urlParts = parse_url($url); $headers = array(); $headers[] = 'Content-Type: application/x-www-form-urlencoded; charset=utf-8'; $headers[] = 'Content-Length: ' . strlen($post); $headers[] = 'Connection: close'; // Force servers to close the connection $headers[] = 'Host: ' . $urlParts['host']; // Required for HTTP 1.1 $options['http']['header'] = $headers; $context = stream_context_create($options); file_get_contents($url, false, $context); Expected result: ---------------- The hexdump of the TCP traffic should appear like thus: 00000000 50 4f 53 54 20 2f 70 6f 73 74 20 48 54 54 50 2f |POST /post HTTP/| 00000010 31 2e 31 0d 0a 43 6f 6e 74 65 6e 74 2d 54 79 70 |1.1..Content-Typ| 00000020 65 3a 20 61 70 70 6c 69 63 61 74 69 6f 6e 2f 78 |e: application/x| 00000030 2d 77 77 77 2d 66 6f 72 6d 2d 75 72 6c 65 6e 63 |-www-form-urlenc| 00000040 6f 64 65 64 3b 20 63 68 61 72 73 65 74 3d 75 74 |oded; charset=ut| 00000050 66 2d 38 0d 0a 43 6f 6e 74 65 6e 74 2d 4c 65 6e |f-8..Content-Len| 00000060 67 74 68 3a 20 36 0d 0a 43 6f 6e 6e 65 63 74 69 |gth: 6..Connecti| 00000070 6f 6e 3a 20 63 6c 6f 73 65 0d 0a 48 6f 73 74 3a |on: close..Host:| 00000080 20 6c 6f 63 61 6c 68 6f 73 74 0d 0a 0d 0a 53 61 | localhost....Sa| 00000090 6d 70 6c 65 |mple| 00000094 Actual result: -------------- This is what I actually capture as TCP traffic 00000000 50 4f 53 54 20 2f 70 6f 73 74 20 48 54 54 50 2f |POST /post HTTP/| 00000010 31 2e 31 0d 0a 43 6f 6e 74 65 6e 74 2d 54 79 70 |1.1..Content-Typ| 00000020 65 3a 20 61 70 70 6c 69 63 61 74 69 6f 6e 2f 78 |e: application/x| 00000030 2d 77 77 77 2d 66 6f 72 6d 2d 75 72 6c 65 6e 63 |-www-form-urlenc| 00000040 6f 64 65 64 3b 20 63 68 61 72 73 65 74 3d 75 74 |oded; charset=ut| 00000050 66 2d 38 0d 0a 43 6f 6e 74 65 6e 74 2d 4c 65 6e |f-8..Content-Len| 00000060 67 74 68 3a 20 36 0d 0a 43 6f 6e 6e 65 63 74 69 |gth: 6..Connecti| 00000070 6f 6e 3a 20 63 6c 6f 73 65 0d 0a 48 6f 73 74 3a |on: close..Host:| 00000080 20 6c 6f 63 61 6c 68 6f 73 74 0d 0a 0d 0a 53 61 | localhost....Sa| 00000090 6d 70 6c 65 0d 0a 0d 0a |mple....| 00000098 -- Edit bug report at http://bugs.php.net/bug.php?id=55010&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=55010&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=55010&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=55010&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=55010&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=55010&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=55010&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=55010&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=55010&r=needscript Try newer version: http://bugs.php.net/fix.php?id=55010&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=55010&r=support Expected behavior: http://bugs.php.net/fix.php?id=55010&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=55010&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=55010&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=55010&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=55010&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=55010&r=dst IIS Stability: http://bugs.php.net/fix.php?id=55010&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=55010&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=55010&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=55010&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=55010&r=mysqlcfg
