Yeah, I thought about "context" going out of scope just after sending the email.

Thanks!

Because I need to variables:

- "this" witch technically may be 
  captured by reference as well, but not really needed.
- "context" - the shared_ptr on the http::context that
  would go out of scope when the callback is called.

Because I don't use URL dispatching so I don't need url variable,

Hi, I have a question about:

context->async_on_peer_reset([=](){
         this->waiters_.erase(context);
});

Why are you catching things in the labda by value, not by reference?

Hey, I have to point out two mistakes:
<title>Chat Room</title>
In the_ticker.html

Also there is the jQuery script in the_ticker.html that is not needed since 
you're using plain JS for this example.

Yeah this is more of a feature, what I did was a proof of concept for myself to

Re: [Cppcms-users] Server Sent events and CppCMS

[Artyom B. <art...@ya...>]

I had changed your example a little:

1. Remove context from the list such that it would not write some more data
   until completion handler returns.
2. You use incorrectly completion handler - you need to receive the status
   in handler.
3. Reduced reconnect option so the client would reconnect immediatly


Also it would be better to use Last-Event-ID header and setup ids so the
client that is disconnected can reconnect and restart from correct point.

Small notes about streaming and flushing:

- In CppCMS internal server works 100%,
- In Lighttpd works 100%
- In Apache - it is required to add -flush option
- In nginx:
-- scgi it is required to add scgi_buffer off; option
-- fastcgi ... It is not possible to disable buffering - at least I 

   had not found one

   Once agains... STUPID nginx






Best,

Thak you.

If I understood correctly the two binded arguments are:
* the first for setting the instance of the objcact from where the member 
pointer should be called from
* the 2nd arg. for setting the actual parameter of the called member function

Re: [Cppcms-users] Server Sent events and CppCMS

[Barbu P. - G. <bar...@gm...>]

Hi again.

So I managed to implement a chat using SSE and CppCMS, you can find it here:

https://gist.github.com/3307849

(the Makefile and config.js are the same ones as in the "Implementing Chat" 
tutorial)

It's just a proof of concept, it has issues:

The biggest one is that after I send some messages and wait for about 30 seconds 
the following error appears:
http://i.imgur.com/jtQUZ.png

If I refresh the page everything seems fine again, then if I wait 30 seconds 
with no activity the error appears. I think this is somehow related to 
chat::get(), but I'm not really sure.

What response is generated if chat::get() sends no explicit response?


The second issue is the TODO in chat.cpp.

[Cppcms-users] Implementing chat question

[Barbu P. - G. <bar...@gm...>]

Hi.

I don't understand the bind() call when binding the arguments to 
chat::remove_context.

chat::remove_context takes only one parameter, but there are binded two, how can 
that be possible?

I'm talking about:

booster::shared_ptr<cppcms::http::context> context=release_context();
waiters_.insert(context);
context->async_on_peer_reset(
     bind(
         &chat::remove_context,
         booster::intrusive_ptr<chat>(this),
         context));

and:

void remove_context(booster::shared_ptr<cppcms::http::context> context)
{
     waiters_.erase(context);
}

Re: [Cppcms-users] Server Sent events and CppCMS

[Artyom B. <art...@ya...>]

I'm really glad that you brought it up because:

	1. It is very easy to implement
	2. It is supported by most (but IE) browsers
	3. It can be easily substituted with long polling if the browser does not support EventSource (like IE) with minimal changes.

	4. It does not require changes in HTTP protocol or underlying APIs like FastCGI/SCGI to implement server side events
	5. It already defines queuing that is most common case of COMET.
	6. In terms of performance in event dispatching it is as fast as WebSockets
	7. The only drawback in comparison with WebSockets is that client can't do very fast server notification - but in general client does not have to fire too many events.
	8. It does not seems to have two hundred of incompatible versions implemented on different levels by different browsers (such that some of them are not PROXY compatible) as web socket.
Bottom line - it seems like a sane and modern approach to modern Comet (unlike WebSockets that you even can't implement over FastCGI)

How could I miss such a cook HTML5 feature!
