ID: 51723 Updated by: [email protected] Reported by: anatoli at adt dot ee Summary: Content-length header is limited to 32bit integer -Status: Bogus +Status: Assigned Type: Bug Package: Apache2 related Operating System: vista 32 PHP Version: 5.2.13 -Assigned To: +Assigned To: pajoye New Comment: "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?" No, thanks. Does it work with apache on unix as well? If yes, is it a 64bit or 32bit machine? The problem could be still the 32bit limitation as the apache2 SAPI replaces the headers with the correct length using strtol, which converts a string to a long. A long is always 32bit on Windows. I will check that code, needs some tweak on Windows (no luck I think on unix 32bit). Previous Comments: ------------------------------------------------------------------------ [2010-05-03 01:50:11] anatoli at adt dot ee 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. ------------------------------------------------------------------------ [2010-05-03 01:41:29] [email protected] 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
