Hello all,
I'm using nsIInputStreamPump to asynchronously read string data from a
socket from JavaScript in my XULRunner application. I've got everything
working except one small problem - I can't keep the socket connection
opened!
Data streams down fine but when there's nothing there it closes after a
few seconds, then I have to re-open. This is regardless of what setting I
use for nsISocketTransportService.setTimeout for both TIMEOUT_CONNECT and
TIMEOUT_READ_WRITE. Is there another setting somewhere maybe for
nsIRequest that configures a separate timeout?
Thanks in advance for any help.
Below is the relevant code...

(function() {
...
const nsISocketTransportService =
Cc["@mozilla.org/network/socket-transport-service;1"]
.getService(Ci.nsISocketTransportService);
this.connect = function (aHost, aPort)
{
...
_tpSrv = nsISocketTransportService.createTransport(null, 0, aHost,
aPort, null);
//_tpSrv.setTimeout(Ci.nsISocketTransport.TIMEOUT_CONNECT, 0xFFFFFFFF);
//_tpSrv.setTimeout(Ci.nsISocketTransport.TIMEOUT_READ_WRITE,
0xFFFFFFFF);
_asyncPacketReader = new AsyncPacketReaderUTF8(
_tpSrv.openInputStream(0, 0, 0), //
Non-Blocking, Buffered
PACKET_END,
that.onPacketArrived);
...
};
...
}).apply(venkLink.client);
AsyncPacketReaderUTF8 = function (aInputStream, aPacketEndStr,
oOnPacketArrived)
{
...
var _isp = Cc["@mozilla.org/network/input-stream-pump;1"]
.createInstance(Ci.nsIInputStreamPump);
_isp.loadFlags |= Ci.nsIRequest.LOAD_BYPASS_CACHE;
_isp.init(aInputStream, -1, -1, 0, 0, false);
/** @type {nsIStreamListener : nsIRequestObserver} Implementation */
var _sl = {};
_sl.onStartRequest = function (request, context) {};
_sl.onStopRequest = function (request, context, status) {};
_sl.onDataAvailable = function (request, context, inputStream, offset,
count)
{
var cis = Cc["@mozilla.org/intl/converter-input-stream;1"]
.createInstance(Ci.nsIConverterInputStream);
var wrapStr = {};
cis.init(inputStream, "UTF-8", 0, 0);
cis.readString(count, wrapStr);
...
};
_isp.asyncRead(_sl, null);
};
