+/**
+ * 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';

+ * $inPath = 'http://carsten.codimi.de/gzip.yaws/daniels.html?deflate=on&zlib=on';
+ * #$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,

+/**
+ * Base PEAR_Exception Class
+ *
+ * 1) Features:
+ *
+ * - Nestable exceptions (throw new PEAR_Exception($msg, $prev_exception))
+ * - Definable triggers, shot when exceptions occur
+ * - Pretty and informative error messages
+ * - Added more context info available (like class, method or cause)
+ * - cause can be a PEAR_Exception or an array of mixed
+ *   PEAR_Exceptions/PEAR_ErrorStack warnings
+ * - callbacks for specific exception classes and their children
+ *
+ * 2) Ideas:
+ *
+ * - Maybe a way to define a 'template' for the output
+ *
+ * 3) Inherited properties from PHP Exception Class:
+ *
+ * protected $message
+ * protected $code
+ * protected $line
+ * protected $file
+ * private   $trace
+ *
+ * 4) Inherited methods from PHP Exception Class:
+ *
+ * __clone
+ * __construct
+ * getMessage
+ * getCode
+ * getFile
+ * getLine
+ * getTraceSafe
+ * getTraceSafeAsString
+ * __toString
+ *
+ * 5) Usage example
+ *
+ * <code>
+ *  require_once 'PEAR/Exception.php';
+ *
+ *  class Test {
+ *     function foo() {
+ *         throw new PEAR_Exception('Error Message', ERROR_CODE);
+ *     }
+ *  }
+ *
+ *  function myLogger($pear_exception) {
+ *     echo $pear_exception->getMessage();
+ *  }
+ *  // each time a exception is thrown the 'myLogger' will be called
+ *  // (its use is completely optional)
+ *  PEAR_Exception::addObserver('myLogger');
+ *  $test = new Test;
+ *  try {
+ *     $test->foo();
+ *  } catch (PEAR_Exception $e) {
+ *     print $e;
+ *  }
