Bug description: zlib.inflate Stream Filter Broken
Description:
------------
The ZLib "inflate" stream filter appears to be broken in PHP 5.2.9 and
5.2.10. When trying to inflate a GZip file, or even a stream previously
compressed with zlib.deflate, zlib.inflate returns no output.
Reproduce code:
---------------
<?php
//zlibtest.php
//Usage:
// $ echo TEST TEST TEST | gzip | php zlibtest.php
$input = fopen("php://stdin", "rb");
stream_filter_append($input, 'zlib.inflate', STREAM_FILTER_READ);
while(!feof($input) && ($buffer = fread($input, 8192)) !== FALSE)
fwrite(STDOUT, $buffer);
fclose($input);
//Inexplicably, this will produce no output on STDOUT.
//Even the example at http://us3.php.net/filters.compression behaves
incorrectly.
?>
Expected result:
----------------
I expect to see "TEST TEST TEST" on the command line.
Actual result:
--------------
The zlib.inflate filter is clearly not producing decompressed results on
fread() operations. By my reckoning, this is a problem.
