Subject: New CometD documentation
Hi,

I have put online the new CometD 2.4.0 documentation at
http://docs.cometd.org/reference.

The new documentation is much improved over the previous one, with
many sections added, and hopefully will ease contributions since it's
written in docbook and hosted at GitHub, so anyone can fork and
request a pull.

We are in the process of expanding the documentation by adding
tutorials, for an easier path to learn CometD.

I'd appreciate any comment on the new documentation, especially about
the "concepts" sections, see
http://docs.cometd.org/reference/#concepts.

Any idea, or suggestion or improvement you want to see about the docs, speak up.

The documentation was the last step holding the release of CometD
2.4.0 final, which will be hopefully tomorrow.

Simon

Thanks for the new documentation. I have struggled a little to get up
to speed with Cometd, and it looks quite detailed :o)

The concepts section makes sense to me, although I already understood
it :op

I would like to see an explanation for 6.4 - 6.7 about when you would
use the extensions, and why you should. And I guess when you
shouldn't.

The area I am most unsure about is what happens across page loads.
Including if I have the reload extension and/or the acknowledge
extension on.

Maybe a few common scenarios and what configuration you should use is
another idea. My guess of common scenarios are:
 - Single Page Chat
 - Multiple Page Chat
  - How to ensure they don't miss a message across page reloads.
 - Multiple Page Alerts (i.e. instant alert when an event occurs
across an entire website)
  - This is what I am using it for. When the page is rendered it
contains the alert count, and then it subscribes to /user/alerts (race
condition?).
 - Twitter style 20 new tweets.
 - Stockmarket Ticker
  - Losing messages is ok for this scenario

Makes sense. Can you please file a JIRA task under the "documentation"
component at http://bugs.cometd.org ?

Ok, same as above, file a JIRA.

This could be a tutorial.

I am guessing it's too complicated for a tutorial.

Ack extension, could be another tutorial.

If I understand correctly, this is already present out of the box: if
you open 2 browsers of the chat demo, they both receive the chat
message.

Not following.

Not sure I understand this precisely.

>  - Stockmarket Ticker

Perhaps another tutorial.

>  - Losing messages is ok for this scenario

Not sure what scenario you refer to.

Thanks much for the feedback.

I have raised the 2 JIRA.

Regarding the twitter example, if you sit on a page on twitter it will
update and say "20 new tweets" at the top of the stream.

Regarding the alert example, its probably too specific to bother with
an example. The main thing I need to understand is page reoloads which
is covered by one of the JIRA.

Regarding loosing messages, for a stock market realtime you always
want to show the latest price. Order is not really important (discard
old ones), and lost messages are ok (just want latest).
