Edit report at http://bugs.php.net/bug.php?id=52679&edit=1 ID: 52679 Comment by: dominic dot benson at thirdlight dot com Reported by: dominic dot benson at thirdlight dot com Summary: Content-length header is limited to 32bit integer Status: Open Type: Feature/Change Request Package: Apache2 related Operating System: Linux 32 PHP Version: 5.3.3 Block user comment: N New Comment: Correction to the above - clearly I mean strtol and strtoll rather than strtocol and strtocoll. Previous Comments: ------------------------------------------------------------------------ [2010-08-23 21:24:32] dominic dot benson at thirdlight dot com Description: ------------ As per #51723, the content-length header is limited to 2GB - however it need not be. If Apache 2.2 is built with -DLARGEFILE_SOURCE -DFILE_OFFSET_BITS=64 then apr_off_t is an off64_t, however the conversion in the calls to ap_set_content_length uses strtocol (hence limited to the 32-bit long on Linux 32), but if strtocoll is used instead to return a 64-bit long long, the header is set correctly for values > 2GB. The attached patch is of the adjustment, I guess the configure script generation needs to be updated to establish whether apr_off_t is long or long long. Test script: --------------- <?php header("Content-Length: 10000000000"); ?> Expected result: ---------------- A header: Content-Length: 10000000000 Actual result: -------------- A header: Content-Length: 2147483647 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52679&edit=1
