#40735 [NEW]: stream_select returns 0 for php > 5.1.6

From: rodricg at sellingsource dot com Operating system: x86_64 GNU/Linux PHP version: 5CVS-2007-03-05 (snap) PHP Bug Type: Streams related Bug description: stream_select returns 0 for php > 5.1.6 Description: ------------ Since php 5.2.0 stream_select fails to return the number of modified descriptors on a 64bit Linux OS (32bit seems to be immune to this). Verified to exist in the php-snap php5.2-200703052130. This bug is the same as #40458 but I am unable to modify the status of that bug. Reproduce code: --------------- <?php $sock = stream_socket_client('tcp://maila.microsoft.com:25', $eno, $estr, 10, STREAM_CLIENT_CONNECT); stream_set_blocking($sock, 0); sleep(1); $r = $w = array($sock); $n = stream_select($r, $w, $e = NULL, 10); echo "Selected: {$n}\n"; echo "Read: ", print_r($r,1); echo "Write: ", print_r($w,1); ?> Expected result: ---------------- Selected: 2 Read: Array ( [0] => Resource id #5 ) Write: Array ( [0] => Resource id #5 ) Actual result: -------------- Selected: 0 Read: Array ( [0] => Resource id #5 ) Write: Array ( [0] => Resource id #5 ) -- Edit bug report at http://bugs.php.net/?id=40735&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40735&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40735&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40735&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40735&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40735&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40735&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40735&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40735&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40735&r=support Expected behavior: http://bugs.php.net/fix.php?id=40735&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40735&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40735&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40735&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40735&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40735&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40735&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40735&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40735&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40735&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40735&r=mysqlcfg
