#29449 [NEW]: feof hangs on empty tcp stream

From: norxh at binnews dot com Operating system: Windows 2000 PHP version: 5.0.0 PHP Bug Type: Network related Bug description: feof hangs on empty tcp stream Description: ------------ When feof is called on an empty tcp stream opened by fsockopen, php will hang indefinitely. In adition to 5.0.0, I also tested with 5.0.x-dev (Jul 29, 2004 16:30 GMT) and 5.1.x-dev (Jul 29, 2004 14:30 GMT). Each test was run with the cli executable. When attempting to debug this issue with Zend Studio 3.5, I found stopping execution during this hang will cause php.exe or apache.exe to crash when using local or remote debugging respectively. Adding: fwrite($stream, "GET / HTTP1.0\r\n\r\n"); before the call to feof will result in proper execution of the script. Reproduce code: --------------- <? set_time_limit(15); $stream = fsockopen('www.google.com', 80, $errno, $errstr, 5); stream_set_timeout($stream, 5); echo feof($stream) ? 'true':'false'; fclose($stream); ?> Expected result: ---------------- false Actual result: -------------- hang -- Edit bug report at http://bugs.php.net/?id=29449&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=29449&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=29449&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=29449&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=29449&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=29449&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=29449&r=needscript Try newer version: http://bugs.php.net/fix.php?id=29449&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=29449&r=support Expected behavior: http://bugs.php.net/fix.php?id=29449&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=29449&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=29449&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=29449&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=29449&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=29449&r=dst IIS Stability: http://bugs.php.net/fix.php?id=29449&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=29449&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=29449&r=float
