* * Add a session concurrency option per key. Allows developer/config to ↵teravus2013-10-093-8/+21
| | | | specify number of concurrent requests on a service.
* * Move the BasicDOSProtector.cs to OpenSim.Framework (all useful classes ↵teravus2013-10-071-181/+0
| | | | | | belong there.....) * Add an IsBlocked(string Key) method so it can be used more generically. (think.. if we want to rate limit login failures, we could have a call in the Login Service to IsBlocked(uuid.ToString()) and ignore the connection if it returns true, if IsBlocked returns false, we could run the login information and if the login fails we could run the Process method to count the login failures.

| | | | | | | | | HTTP Server handlers. XMLRPC Handler, GenericHttpHandler and <Various>StreamHandler * Applied the XmlRpcBasicDOSProtector.cs to the login service as both an example, and good practice. * Applied the BaseStreamHandlerBasicDOSProtector.cs to the friends service as an example of the DOS Protector on StreamHandlers * Added CircularBuffer, used for CPU and Memory friendly rate monitoring. * DosProtector has 2 states, 1. Just Check for blocked users and check general velocity, 2. Track velocity per user, It only jumps to 2 if it's getting a lot of requests, and state 1 is about as resource friendly as if it wasn't even there.

* Cleared up much confusion in PollServiceRequestManager. Here's the history:Diva Canto2013-07-172-48/+35
| | | | | | When Melanie added the web fetch inventory throttle to core, she made the long poll requests (EQs) effectively be handled on an active loop. All those requests, if they existed, were being constantly dequeued, checked for events (which most often they didn't have), and requeued again. This was an active loop thread on a 100ms cycle! This fixes the issue. Now the inventory requests, if they aren't ready to be served, are placed directly back in the queue, but the long poll requests aren't placed there until there are events ready to be sent or timeout has been reached. This puts the LongPollServiceWatcherThread back to 1sec cycle, as it was before.
* Add request received/handling stats for caps which are served by http poll ↵Justin Clark-Casey (justincc)2013-07-154-50/+69
| | | | | | | handlers. This adds explicit cap poll handler supporting to the Caps classes rather than relying on callers to do the complicated coding. Other refactoring was required to get logic into the right places to support this.

| * BaseHttpServer: if the handler sets the content length, don't override it. ↵Diva Canto2013-07-081-1/+1
| | | | | | | | This happens in HEAD handlers.
* | Add "show caps stats by user" and "show caps stats by cap" console commands ↵Justin Clark-Casey (justincc)2013-07-087-16/+51
|/ | | | | | | | | to print various counts of capability invocation by user and by cap This currently prints caps requests received and handled, so that overload of received compared to handled or deadlock can be detected. This involves making BaseStreamHandler and BaseOutputStream record the ints, which means inheritors should subclass ProcessRequest() instead of Handle() However, existing inheriting classes overriding Handle() will still work, albeit without stats recording. "show caps" becomes "show caps list" to disambiguate between show caps commands

The new timeout checker closes expired keepalive sessions, just make sure you send the request within 70 seconds of connecting or the timeout checker will timeout the connection.
