Bug description: Deflate filter doesn't compress all data
Description:
------------
The deflate filter doesn't compress all data.
The decompressed data is 1721662 bytes long.
Reproduce code:
---------------
<?php
$f = fopen("http://republika.pl/rkd/data.bz2";, "rb");
$data = '';
while (!feof($f)) {
$data .= fread($f, 32768);
}
fclose($f);
$text = bzdecompress($data);
$f3 = fopen("data.html.deflate", "wb");
stream_filter_append($f3, 'zlib.deflate', STREAM_FILTER_WRITE);
fwrite($f3, $text); fclose($f3);
$f5 = fopen("data.html.deflate", "rb");
stream_filter_append($f5, 'zlib.inflate', STREAM_FILTER_READ);
$text_deflate = ''; while (!feof($f5)) { $text_deflate .= fread($f5,
32768); } fclose($f5);
printf("original = %d, deflate = %d\n", strlen($text),
strlen($text_deflate));
?>
Expected result:
----------------
original = 1721662, deflate = 1721662
Actual result:
--------------
original = 1721662, deflate = 546816
