Hi again Ernie,
I've just committed a few improvements.
In terms of debugging if you specify
cmake .. -DCMAKE_BUILD_TYPE=Debug
or
cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo
it will do a build with no JavaScript optimisations and no closure
compiler so any JavaScript errors will be a bit more human readable. The
default build does full Clang optimisations and JavaScript/asm.js
optimisations and minifies/optimises with the closure compiler.
I added code to the status and isBuffered methods that checks for a null
tracker being passed, and if so they now retrieve the outgoing tracker
and use that.
I've also added a soak test and a little send.html
I need to take a look at error handling - if I try to send when there's
no receiver it gets in a state where it won't subsequently send messages
when the receiver is restarted. I might just need to stop and restart
Messenger - TBH I can't claim to really understand the Messenger API.
Hope that you are having fun with this stuff.

Hi Fraser,
I'm trying to run the proton javascript bindings from within a browser. I'm
getting various errors depending on the way I'm doing it and I was hoping you
could shed some light on the correct approach.
I have node recv.js running in a separate window.
The first way I tried was just including proton.js directly. When I load the
page the console shows the following for the HTML listed below:
pre-main prep time: 6 ms
proton is [object Object]
before put
Uncaught TypeError: Cannot read property 'fa' of null
Uncaught TypeError: Cannot read property 'fa' of null
Here is the HTML:

console.log("proton is " + window.proton);
var address = "amqp://0.0.0.0";
var subject = "BrowserMessage";
var msgtext = "Hello From Browser!";
var tracker = null;
var running = true;
var message = new proton.Message();
var messenger = new proton.Messenger();
var pumpData = function() {
var status = messenger.status(tracker);
if (status != proton.Status.PENDING) {
if (running) {
messenger.stop();
running = false;
}
}
if (messenger.isStopped()) {
message.free();
messenger.free();
}
};
messenger.on('error', function(error) {console.log("this is the error" +
error);});
messenger.on('work', pumpData);
messenger.setOutgoingWindow(1024);
messenger.start();
message.setAddress(address);
message.setSubject(subject);
message.body = msgtext;
console.log("before put");
messenger.put(message);
//]]>
</script>
</head>
<body>
</body>
</html>
The output in the window running node recv.js is:
[0x535398]:ERROR[-2] AMQP header mismatch: '' (connection aborted)
CONNECTION ERROR connection aborted (remote)
When I browserify the proton.js into qpid-proton-browser.js and load that file
instead, I get the following when the page loads:
Uncaught TypeError: Cannot read property 'replace' of undefined
proton is undefined
Uncaught ReferenceError: proton is not defined
The Uncaught TypeError is due to a referece to "process.argv[1]". If I manually edit the
qpid-proton-browser.js file to define all the process properties that it wants, I still get the
"proton is undefined" error.
Do you know what I'm doing wrong?
Thanks,
-Ernie
