Bug description: if userspace stream is present, fread() reads in 8192 max,
otherwise it works
Description:
------------
fread($fp, 20000); will read in 20000 bytes from a local file, but is a
userspace stream is defined anywhere, it will only read in 8192 bytes,
without any warning or error.
This is actually similar to Bug #30936, but as I say the problem here is
that the presence of a userspace stream handler changes the behavior of
fread() - any indeterminate behavior is bad.
I wonder if the fix from #32810 could be helpful for this problem as well?
Reproduce code:
---------------
<?php
// paste in the stream code from the example in the manual
// be sure to include stream_wrapper_register
error_reporting(E_ALL | E_STRICT);
$file = dirname(__FILE__) . '/footest.txt';
$x = str_repeat('1', 8192);
$fp = fopen($file, 'w');
for ($i = 0; $i < 5; $i++) {
fwrite($fp, $x);
}
fclose($fp);
$fp = fopen($file, 'r');
$outsidecontents = fread($fp, 20000);
fclose($fp);
var_dump('size of contents 1 = ' . strlen($outsidecontents));
$outsidecontents = file_get_contents($file);
var_dump('size of contents 2 = ' . strlen($outsidecontents));
?>
Expected result:
----------------
string(26) "size of contents 1 = 20000"
string(26) "size of contents 2 = 40960"
Actual result:
--------------
string(25) "size of contents 1 = 8192"
string(26) "size of contents 2 = 40960"
