		"description": "If writeStream(inputStream, outputStream, chunkSize, callback) is invoked when the input stream is at end of stream, behavior varies by platform. Neither platform appears to follow the spec.\r\n\r\nFrom my reading of the spec, it's not clear what's supposed to happen. For the pump callback it specifically says that the bytesProcessed property in the callback arg is set to -1 on end of stream. \r\n\r\nOn iOS, an exception is thrown, so the callback isn't invoked.\r\n\r\nOn Android, bytesProcessed is set to 0 in the callback, errorState is 0, and errorDescription is \"\". \r\n\r\nIt seems like it would be more consistent with other functionality if bytesProcessed reported -1 in both cases.\r\n\r\nSame behavior holds for the synchronous version of the method--returns 0 on Android, throws an exception on iOS.\r\n\r\nIf we regard passing an empty stream (or a stream at EOF) as an error, we should treat it as an error on both platforms.\r\n\r\nTestcase:\r\n\r\n{code}\r\nvar win1 = Titanium.UI.createWindow({  \r\n    title:'Tab 1',\r\n    backgroundColor:'#fff'\r\n});\r\nwin1.open();\r\n\r\nvar stream1 = Ti.Stream.createStream({ \r\n\tsource: Ti.createBuffer({ length: 0}),\r\n\tmode: Ti.Stream.MODE_READ\r\n});\r\n\r\nvar stream2 = Ti.Stream.createStream({ \r\n\tsource: Ti.createBuffer({ length: 1024}),\r\n\tmode: Ti.Stream.MODE_READ\r\n});\r\n\r\nTi.Stream.writeStream(stream1, stream2, 1024, function(arg) {\r\n\tTi.API.info(\"bytes processed: \" + arg.bytesProcessed);\r\n\tTi.API.info(\"Event: \" + JSON.stringify(arg, false, 2));\r\n});\r\n{code}\r\n\r\nPlease clarify expected behavior.",
