#47893 [NEW]: CLI script with non-blocking STDIN terminates randomly
From: jon at thesquareplanet dot com
Operating system: Debian Lenny
PHP version: 5.2CVS-2009-04-03 (snap)
PHP Bug Type: Reproducible crash
Bug description: CLI script with non-blocking STDIN terminates randomly
Description:
------------
When setting STDIN to be non-blocking, and then running fread() on it, the
cli script suddenly terminates at a seemingly random point during the
reading. No error message is given.
Seemingly related bugs:
http://bugs.php.net/bug.php?id=25616 <-- This
is the same bug, but has
erroneously been labeled as a dupe of the one below
http://bugs.php.net/bug.php?id=25575 <-- This
bug describes a somewhat
similar, though not nearly identical, problem
These bugs are both set as last modified in 2003/2004, but the issue
remains unfixed.
Reproduce code:
---------------
<?php
stream_set_blocking(STDIN, FALSE);
while (1) {
var_dump(fread(STDIN,1));
echo "\n";;
}
?>
Expected result:
----------------
A never-ending sequence of var_dumps of either an empty string or a typed
character
Actual result:
--------------
The expected output, but only for a short while, and then the script
terminates
