Length bytes have not been read and EOF was not reached, this is not a
network stream.

In the example code there *are* 15000 bytes available to read. Regular
file system functions, compress.zlib (didn't try other builtin streams)
and PHP <= 4.3.8 have no problem reading more than 8192 bytes in one
hit.

I can't find any reference to an 8192 limit anywhere in the manual.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

http://php.net/fread says:

fread() reads up to length bytes from the file pointer referenced by
handle

note the \"up to\".

Description:
------------
Attempting to fread() more than 8192 bytes from a userspace stream
wrapper will only read and return the first 8192 bytes, putting an echo
statement in stream_read() shows that it is only being called once.

Reading <= 8192 bytes at a time works as expected, as does fgets($f,
15000) (reads 14999 bytes).

This bug is only present in 4.3.9 and 4.3.10RC1, 4.3.8 works fine. 

Reproduce code:
---------------
<?php

// using example class from the manual: 
// http://uk.php.net/stream_wrapper_register

$x = str_repeat('x', 15000);
$f = fopen('var://x', 'r');
$len = strlen(fread($f, 15000));
fclose($f);

echo "Read $len bytes";

?>

Expected result:
----------------
Read 15000 bytes

Actual result:
--------------
Read 8192 bytes
