#19886 [Fbk]: readfile, fread, fpassthru won't work with large files!!!

ID: 19886 Updated by: spic@php.net Reported By: spic@php.net Status: Feedback -Bug Type: Reproducible crash +Bug Type: Performance problem Operating System: Windows, any Version PHP Version: 4CVS-2002-10-13 New Comment: @wez: These scripts don't use sessions. They run of a CD in a single-user-environment. @nicos: Calling the "passthrough"-script directly works without errors. But calling it in an frameset (together with two other scripts) crashes when outputting a file > 100k, The php_stream_read() returns the correct filesize. The fact, that the parrallel execution of three scripts of one handles a big file may be the source of the problem. There are no write-accesses. Only Read-Accesses to small config-files. Removing the "big-files-passthrough" let the scripts run properly. Previous Comments: ------------------------------------------------------------------------ [2002-10-13 10:02:11] wez@php.net Can you reduce this to the simplest combination of scripts? (That don't use sessions). ------------------------------------------------------------------------ [2002-10-13 09:37:40] nicos@php.net did you checked if php_stream_read() was returning the right filesize value? that was the first bug. ------------------------------------------------------------------------ [2002-10-13 09:10:57] spic@php.net Note: Calling sleep(5) before dumping the PDF solves the problem, so I think the bug is related to a memory management/multithreading problem... ------------------------------------------------------------------------ [2002-10-13 09:08:03] spic@php.net Environment: Windows WebServer: Microweb (CD-WebServer) PHP-Version: Latest CVS and 4.2.4-dev PHP is installed as CGI In a frameset-environment, PHP hangs while outputting large PDF-Files. The Frameset consists of three Frames. Every Frame is PHP-generated. One functions as "PDF-Passthrough". All works fine, if the Passthrough-File is smaller than approx. 100k. Files >100k make the system hang. Calling the passthrough-script directly (w/o frameset) causes no problems. There is no difference between using readfile, fpassthru, or fread. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19886&edit=1
