Bug description: stream-set_blocking() causes unexpected non erroneous exit from
script.
Description:
------------
When I use stream_set_blocking() to make the standard input file handle
non-blocking the script exits seemingly random. For example the $count
output can have a last printed value anywhere from 200 to 3000.
Reproduce code:
---------------
<?
if( ($stdin = fopen( 'php://stdin', 'r' )) === false )
{
echo 'Failed to open STDIN'."\n";
exit();
}
stream_set_blocking( $stdin, false );
$count = 0;
while( 1 )
{
echo 'Count: '.($count++)."\n";
if( ($char = fread( $stdin, 1 )) != '' )
{
echo 'Char: '.$char."\n";
}
else
{
echo 'Fooo!'."\n";
}
}
Expected result:
----------------
Script should run forever since it is in a while( 1 ) loop. This was done
on purpose for testing purposes. At each pass of the loop it should print
the current $count index, then if data exist in $stdin then it should
print the character, otherwise print Fooo! to the screen.
Actual result:
--------------
Script does not run forever. Script exits and the last count printed can
be anywhere from 200 to 3000 -- it seems kind of random. I ran the script
through gdb and gdb indicates that the program (PHP) exits properly. Thus
there is no backtrace to provide.
