Bug #51723 [Bgs]: Content-length header is limited to 32bit integer

Edit report at http://bugs.php.net/bug.php?id=51723&edit=1 ID: 51723 User updated by: anatoli at adt dot ee Reported by: anatoli at adt dot ee Summary: Content-length header is limited to 32bit integer Status: Bogus Type: Bug Package: Apache2 related Operating System: vista 32 PHP Version: 5.2.13 New Comment: The problem is not in the filesize. Headers was checked with the latest wireshark. Under the cgi i receive correct header. Under sapi not. Do i must provide here code that allow downloads for files till 8Gb with multiple threads and resume support, witch is working under unix cgi, and not under win32 sapi? I redused test case to exactly minimum amount of code needed to reproduce error. Previous Comments: ------------------------------------------------------------------------ [2010-05-03 01:41:29] pajoye@php.net The header is correctly sent without modification (you can verify that using cgi in the console). However PHP does not support large file support and only 2^31 bytes are read and sent. There is already a feature request for LFS > mark this one as duplicated (bogus). ------------------------------------------------------------------------ [2010-05-03 00:58:57] anatoli at adt dot ee Description: ------------ Content-length header is limited to 32bit integer on wista 32 systems under apache 2 sapi. header("Content-Length: 2967901695"); Expected on client - Content-Length: 2967901695 Actual - Content-Length: 2147483647 Test script: --------------- <?php header($_SERVER['SERVER_PROTOCOL'].' 200 OK'); header('Accept-Ranges: bytes'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename=test.txt'); header("Content-Transfer-Encoding: binary"); header("Content-Length: 2967901695"); header('Connection: close'); //we open file with size exactly 2967901695 bytes $fp = fopen("somefile.name", 'rb'); fpassthru($fp); ?> Expected result: ---------------- Content-Length: 2967901695 Actual result: -------------- Content-Length: 2147483647 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51723&edit=1
