/**
* An observer that saves response body to stream, possibly uncompressing it
*
* This Observer is written in compliment to pear's HTTP_Request2 in order to
* avoid reading the whole response body in memory. Instead it writes the body
* to a stream. If the body is transferred with content-encoding set to
* "deflate" or "gzip" it is decoded on the fly.
*
* The constructor accepts an already opened (for write) stream (file_descriptor).
* If the response is deflate/gzip encoded a "zlib.inflate" filter is applied
* to the stream. When the body has been read from the request and written to
* the stream ("receivedBody" event) the filter is removed from the stream.
*
* The "zlib.inflate" filter works fine with pure "deflate" encoding. It does
* not understand the "deflate+zlib" and "gzip" headers though, so they have to
* be removed prior to being passed to the stream. This is done in the "update"
* method.
*
* It is also possible to limit the size of written extracted bytes by passing
* "max_bytes" to the constructor. This is important because e.g. 1GB of
* zeroes take about a MB when compressed.
*
* Exceptions are being thrown if data could not be written to the stream or
* the written bytes have already exceeded the requested maximum. If the "gzip"
* header is malformed or could not be parsed an exception will be thrown too.
*
* Example usage follows:
*
* <code>
* require_once 'HTTP/Request2.php';
* require_once 'HTTP/Request2/Observer/UncompressingDownload.php';
*
* #$inPath = 'http://carsten.codimi.de/gzip.yaws/daniels.html';
* #$inPath = 'http://carsten.codimi.de/gzip.yaws/daniels.html?deflate=on';
* $inPath = 'http://carsten.codimi.de/gzip.yaws/daniels.html?deflate=on&zlib=on';
* #$outPath = "/dev/null";
* $outPath = "delme";
*
* $stream = fopen($outPath, 'wb');
* if (!$stream) {
* throw new Exception('fopen failed');
* }
*
* $request = new HTTP_Request2(
* $inPath,
* HTTP_Request2::METHOD_GET,
* array(
* 'store_body' => false,
* 'connect_timeout' => 5,
* 'timeout' => 10,
* 'ssl_verify_peer' => true,
* 'ssl_verify_host' => true,
* 'ssl_cafile' => null,
* 'ssl_capath' => '/etc/ssl/certs',
* 'max_redirects' => 10,
* 'follow_redirects' => true,
* 'strict_redirects' => false
* )
* );
*
* $observer = new HTTP_Request2_Observer_UncompressingDownload($stream, 9999999);
* $request->attach($observer);
*
* $response = $request->send();
*
* fclose($stream);
* echo "OK\n";
