Bug #66266 [NEW]: socket_sendto always returns true

From: chuck at jumis dot com Operating system: Darwin Kernel Version 13.0.0 PHP version: 5.4.22 Package: Sockets related Bug Type: Bug Bug description:socket_sendto always returns true Description: ------------ This always returns true, and the full amount of bytes, even when the remote port is closed. Running socket_recvfrom simply results in an Unavailable error. This is in contrast to running something like socat which will return an error after sending data. Note that the manual does say that UDP connections should return an error following socket_sendto. I've not been able to find a work-around. At present I simply can not test if the target UDP port is open. May be an ICMP issue. Test script: --------------- $fp = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP); $bytes = socket_sendto($fp, $json."\n", strlen($json)+1, 0, $ip, $port); $fp && $bytes > 0 && socket_last_error($fp) == 0; Expected result: ---------------- When the remote UDP port is closed, socket_sendto should return false or otherwise socket_recvfrom should return false. Actual result: -------------- The socket pointer and socket_sendto return true -- it is not distinguishable whether or not the remote UDP port is open. -- Edit bug report at https://bugs.php.net/bug.php?id=66266&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66266&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66266&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66266&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66266&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66266&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66266&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66266&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66266&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66266&r=support Expected behavior: https://bugs.php.net/fix.php?id=66266&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66266&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66266&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66266&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66266&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66266&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66266&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66266&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66266&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66266&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66266&r=mysqlcfg
