#19944 [Ctl]: fgets() returns garbage when STDIN set to non-blocking

ID: 19944 Updated by: wez@php.net Reported By: ces@vaultbbs.com Status: Critical Bug Type: Sockets related Operating System: RedHat 7.3 PHP Version: 4.3.0-pre1 New Comment: I've just committed a fix for the STDIN problem; please try the next snapshot (dated/timestamped after this message). Please also test with sockets. Previous Comments: ------------------------------------------------------------------------ [2002-10-19 04:27:16] wez@php.net Can you provide a backtrace for the core-dump? ------------------------------------------------------------------------ [2002-10-18 20:11:55] ces@vaultbbs.com Rats, just changing status to "Open"--already added comment above... ------------------------------------------------------------------------ [2002-10-18 20:11:03] ces@vaultbbs.com As of snap-200210181500 it still doesn't work. Results are the same with garbage returned when using fgets() on STDIN when in non-blocking mode. Last two snaps I've tried (10/17 and 200210181500) have the added feature of also core dumping when fgets() is used on a non-blocking socket opened with fsockopen(). Previous versions of PHP work as expected with fgets() on a non-blocking socket, but the snaps seem to core dump. 10/17 snap would core dump on first call to fgets() whereas today's snap seems to go through the while loop three times and then core dumps when it hits fgets() again. Thus, the current observation is that when using fgets in non-blocking mode: 1. STDIN returns garbage. 2. Sockets core dump. ------------------------------------------------------------------------ [2002-10-17 21:59:58] wez@php.net As an aside: you can use stream_select() to acheive this (see docs for socket_select; they work the same way, but on different things). Also, you should use if ($string !== false) to 100% correct in your script. ------------------------------------------------------------------------ [2002-10-17 17:07:37] sniper@php.net Try this one again: http://snaps.php.net/php4-latest.tar.bz2 You might have got the snapshot which didn't have the fixes. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
