How does PFC check client connections/disconnections?

[Baez]

As the title says, how does PFC check for a client connection. Or more importantly how does it consistently check for users disconnecting or timing out?

Can someone point me to functions that handle this?

Thanks

[Baez]

Anyone have any insight into this? I see the developers have logged in since I've posted this as well.

It just uses a inactivity timeout.

[Baez]

Well it keeps users online until they close the chat window. So how does PFC check for that inactivity or closed window? I'm trying to find it to understand exactly how PFC's inner workings function

When the user has the window open, the page is constantly poling the server for new messages. When the user closes the window, this poling stops. After a given amount of time with no activity, the server considers that user to have closed the window and drops them off the list.

[Baez]

Thanks Wolf but that's exactly my question. How does it perform that constant polling and checking? I'm looking for an answer in programming terms. Like the specific classes and/or functions that perform this. It works very consistently and dependably compared to other chat programs that are constantly dropping users and connections.

[Baez]

Still looking if you can provide an answer

[OldWolf]

Never looked, it would take me as long for me to find it as you, sorry!

[Baez]

No problem thanks Wolf. I'll wait for kerphi to shed some light.

No problem thanks Wolf. I'll wait for kerphi to shed some light.

yeah.. me too..

Technically, it just uses AJAX to check that user is online.

oh Kerphi, i sent ya an email, did ya get it?

[Jaybird]

Kerphi,

I wanted to know where the routine is located, because I want to add a function to clear session data, and refresh to the main page when the script detects a connection drop.

[Jaybird]

Kerphi,

I looked in main.php of en_US from i18n, and I found this:

Code: Select all

// line 25 in send.class.php
$GLOBALS["i18n"]["Your must be connected to send a message"] = "You must be connected to send a message";

I want to find that exact routine, but I went to line 25 of send.class.php and its not there, actually it's not in the code at all, and must have been moved.. any ideas?

I'm having the same error message whenever trying to send a message.

The line that sends the error message is actually in the proxy auth.class.php on line 52.

$cmd->run($xml_reponse, $cmdp); on line 74 of send.class.php triggers the auth (user online) check, which fails for some reason or the other...I'll have to do WAY more digging to find out why, but maybe this info helps someone else figure this bug out, since the developer seems to be unavailable.
