Hi there,
I want to write a server-side JavaScript module for APE that will
handle hundreds of users on multiple active channels. Say I use the
APE server events like this:
Ape.addEvent("beforeJoin", function(user, channel) {
var uname = user.getProperty('name');
var cname = channel.getProperty('name').toLowerCase();
Ape.log("User " + uname + " is joining channel '" + cname + "'");
// Store the user+channel info and do something
});
Is it possible for the event handler to be called by multiple threads
at the same time? Or is all the JavaScript code executed by a single
thread (in which case surely this is a bottleneck for all the incoming
HTTP requests)?
Similarly, if I were to use a global variable to share data between
event handlers, do I need any kind of locking mechanism to prevent
different event handlers accessing the same variable at the same time?
if you have a look at the code, you'll see that it's single
threaded/single process, so, no problems and no need for locking et
al. therefore, also no performance gain on a multi-core server, but
otoh, all processing is asynchronous, so at least one core is used to
the maximum (and another core will be used for sys).
