Implementing JavaScript class (SpiderMonkey) for making http requests

[Leonid Romanov]

Hi!
I need to implement additional "standard" JavaScript class for making http
requests. SpiderMonkey will run as part of embedded browser and I prefer
to implement it inside libmozjs.so, without messing with XPConnect. For
class's users request will look as synchronous, however user can specify
timeout for it, so implementation should be asynchronous.

My plan is following: implement full blown StreamListener, then, inside my
JavaScript class method implementation:

  eventQService->PushThreadEventQueue(getter_AddRefs(mEventQueue)); 
  ...
  mChannel->AsyncOpen(mMyListener, nsnull); 
  ...
  while (mRunEventLoop) {
    mEventQueue->ProcessPendingEvents();
    // timeout stuff using PR_IntervalNow()
  }
  ...
  eventQService->PopThreadEventQueue(mEventQueue);

The big question is: will such aproach work at all? If so, are there any 
pitfalls which I should be aware of? For example, should I process all 
pending events from current event queue before pushing my own? 
Any useful sources from Mozilla's tree to look (so far I'm only found 
nsXMLHttpRequest.cpp)? Docs?

P.S. I'm not too skilful with threads :(

Thanks in advance. 
Leonid.
