[Cppcms-users] questions about chat example code

[CN <cn...@fa...>]

(1) ~/examples/chat/the_chat.html:
Lines 30 and 34 recursively call read_data(). Will these recursive calls
eventually eat up stack memory? If they will, how to improve the code?

~/examples/chat/chat.cpp:

(2) Line 64:
waiters_.insert();
context->async_on_peer_reset()

If the client resets connection between the above two calls, will it
cause memory leak (although the leak is not serious because broadcast()
will call waiters_.clear() eventually)? If it will, does swapping the
orders of these two lines help?

context->async_on_peer_reset()
waiters_.insert();

(3) waiters_ manipulates its elements in get(), remove_context(), and
broadcast(). Do we need to implement lock mechanism on waiters_ to
ensure the code thread safe? If we do, how?

I would appreciate your understanding that I am absolutely not finding
fault with the example code. Rather, I am trying to learn as many as I
can from it.

Regards,
CN
