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
