Bug description: Max reading length of STDIN is 8192bytes
Description:
------------
I write a script which reads a file from STDIN, and writes it out the
content of it to a new file. It worked fine with php 4.3.4, but when I
upgraded to any newer version, then it failed to read the whole file from
stdin. I expected to read the file into a 128000 bytes buffer but it reads
only 8192 bytes instead of 128000 bytes.
Reproduce code:
---------------
<?
$file_length = 6596594;
define("UPLOAD_BUFFER",128000);
if (!$fp = fopen("test.data","w"))
{
die("file open error");
}
$count = (($file_length / UPLOAD_BUFFER));
echo "\nmax i should be: ".$count;
for ($i = 1; $i < $count; $i ++) {
$str = fread(STDIN, UPLOAD_BUFFER);
echo "\ni: ".$i." length:".strlen($str);
fwrite($fp, $str);
}
$remainder = $file_length % UPLOAD_BUFFER;
if (0 != $remainder) {
$str = fread(STDIN, $remainder);
echo "\nlast length:".strlen($str);
fwrite($fp, fread(STDIN, $remainder));
}
fclose($fp);
?>
Expected result:
----------------
If I run my script with this command:
php -q ./my.php < file_with_size_of_6596594_bytes.bin
I expect to get a new file created (test.data), with the same content as
the file_with_size_of_6596594_bytes.bin.
Actual result:
--------------
As a result a new file created (test.data), which is 425984 bytes long.
425984=51*8192+8192
But, it shuld be
6596594=51*128000+68594
