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

ID: 19886 Updated by: wez@php.net Reported By: spic@php.net Status: Feedback Bug Type: Filesystem function related Operating System: Windows, any Version PHP Version: 4CVS-2002-10-13 New Comment: I just fixed (I hope) a socket-shutdown bug (#16114). The interesting thing is that this is only to do with writes to sockets opened by streams (so it should not affect PHP output). It might be that the Microweb server also has a similar bug, or that it has some other threading issue. It doesn't make sense for this to be related solely to streams, as they aren't time-dependent, and they are certainly not dependent on other PHP processes. Can you try reproducing the problem using Apache, PWS or IIS? Can anyone reproduce this on another platform? Previous Comments: ------------------------------------------------------------------------ [2002-10-13 17:21:54] sniper@php.net Did this work in any previous versions of PHP? Is it stricly win32 thing? Does this workin in e.g. Linux? ------------------------------------------------------------------------ [2002-10-13 10:40:41] nicos@php.net May be its because that the stream hasn't enough time to get its new position. I didn't read streams.c/h well enough too. ------------------------------------------------------------------------ [2002-10-13 10:30:31] spic@php.net In addition [frame1.php] <? // Adding sleep(5) will solve the problem the first time a // >100k File is called. The next output of a >100k File // will crash again... sleep(5); header("Content-type: application/pdf\n"); readfile("some_100k_large.pdf"); ?> ------------------------------------------------------------------------ [2002-10-13 10:22:32] nicos@php.net That last comment should let us open it back. Removing the "big-files-passthrough" let the scripts run properly. @Wez: can you check it? may be its because of the position of the stream at the end of the execution of the first checksize? ------------------------------------------------------------------------ [2002-10-13 10:19:11] spic@php.net The following snippets illustrate the environment [frameset.php] ->frame1.php ->frame2.php ->frame3.php [frame1.php] <? header("Content-type: application/pdf\n"); readfile("some_100k_large.pdf"); ?> [frame2.php] <? echo "Something"; ?> [frame3.php] <? echo "else"; ?> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
