Bug #74395 [Com]: Support 4g files in stream_copy_to_stream() on 32 bit php builds

Edit report at https://bugs.php.net/bug.php?id=74395&edit=1 ID: 74395 Comment by: spam2 at rhsoft dot net Reported by: maggus dot staab at googlemail dot com Summary: Support 4g files in stream_copy_to_stream() on 32 bit php builds Status: Open Type: Bug Package: Streams related PHP Version: 7.1.3 Block user comment: N Private report: N New Comment: the better question is why is PHP on 32bit limited that way? couldn't it use longint as other applications do? Previous Comments: ------------------------------------------------------------------------ [2017-04-09 09:47:48] maggus dot staab at googlemail dot com As userland workaround exists for this exists I guess a builtin handling of such files would/should also work? ------- Quote: Got it working with following patch: /www/nextcloud/3rdparty/sabre/http/lib/Sapi.php@78: while (!feof($body)) { // stream_copy_to_stream($body, $output, $contentLength); fwrite($output,fread($body,8192)); } Instead of copying entire file at once, it copies chunks of 8MB Bit crude, but the concept works :) Based on: http://php.net/manual/en/function.stream-copy-to-stream.php#98119 ---------- See https://github.com/nextcloud/server/issues/1707#issuecomment-288890497 ------------------------------------------------------------------------ [2017-04-09 09:34:39] maggus dot staab at googlemail dot com Description: ------------ stream_copy_to_stream() expects the 3rd arg to be a integer which limits its max value on 32 bit builds. This means some real world use cases dont work because the MAX_INT is not big enough to handle 4GB+ filesizes. Could we handle the arg like a string to support "huge files" on 32 bit php? https://github.com/nextcloud/server/issues/1707#issuecomment-288890497 Expected result: ---------------- Copy of streams with filesize >= 4gb should be supported Actual result: -------------- stream_copy_to_stream() expects parameter 3 to be integer, string ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74395&edit=1
