Bug description: stream_get_line eats additional characters
Description:
------------
Calling stream_get_line may eat additional characters when reading a long
line. If the delimiter is not encountered, a number of additional
characters are removed from the stream and are not returned with the next
call to stream_get_line. For some unknown reason, adding \r to the
delimiter makes it work just fine.
Reproduce code:
---------------
<?PHP // 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ
$fp = fopen('test.php', 'r'); // Open myself
DoTest($fp, 'ZZZ'); // Removes 3 characters
DoTest($fp, "\r"); // Doesn't break with \r for some reason
function DoTest($fp, $delim) {
echo "Delim: " . urlencode($delim) . "\n";
rewind($fp);
echo " " . stream_get_line($fp, 10, $delim) . "\n";
echo " " . stream_get_line($fp, 10, $delim) . "\n";
}
Expected result:
----------------
Delim: ZZZ
<?PHP // 1
234567890A
Delim: %0D
<?PHP // 1
234567890A
Actual result:
--------------
Delim: ZZZ
<?PHP // 1
567890ABCD
Delim: %0D
<?PHP // 1
234567890A
