To round out the info, I am using MochiKit 1.3.1. And actually, the
same issue seems to affect IE, Firefox 1.5.1, and Safari. We did try
MochiKit 1.4 also, but it seemed at quick glance to have a similar
problem (becoming unresponsive after a while, though I haven't
specifically watched memory usage).
Here's a minimal version of the problem code (very minimal):
function set_message(message) {
var div = getElement("message");
replaceChildNodes(div, message);
}
function process_data(feed_data) {
set_message(null);
callLater(10, request_updates);
return;
}
function request_updates() {
set_message("Loading...");
var data = loadJSONDoc("get_rss.cgi");
data.addCallbacks(process_data, connection_error);
}
connect(window, 'onload', request_updates);
Obviously, the real version of process_data() does some more
interesting stuff with the 'feed_data' (create some TRs and then
replaceChildNodes() using them). But even this minimal version shows
the memory leak. I watch the memory in Gnome System Monitor (but some
other tool would be the same), and it increases by about 0.5 megs each
reload... the loaded data is identical on each load (for the test
system), and happens to be 150,446 bytes. It's not hard to believe
that the string converted to a data structure might eat a little more
memory though (assuming that is the leak).
Yours, David...
