2013-07-26Fix regression tests relating to agent transfer by making simulator use last ↵Justin Clark-Casey (justincc)1-0/+5
week's SIMULATOR/0.1 protocol for now.
2013-07-24New Teleport protocol (V2), still compatible with V1 and older. (version of ↵Diva Canto1-5/+6
the destination is being checked) In this new protocol, and as committed before, the viewer is not sent EnableSimulator/EstablishChildCommunication for the destination. Instead, it is sent TeleportFinish directly. TeleportFinish, in turn, makes the viewer send a UserCircuitCode packet followed by CompleteMovementIntoRegion packet. These 2 packets tend to occur one after the other almost immediately to the point that when CMIR arrives the client is not even connected yet and that packet is ignored (there might have been some race conditions here before); then the viewer sends CMIR again within 5-8 secs. But the delay between them may be higher in busier regions, which may lead to race conditions. This commit improves the process so there are are no race conditions at the destination. CompleteMovement (triggered by the viewer) waits until Update has been sent from the origin. Update, in turn, waits until there is a *root* scene presence -- so making sure CompleteMovement has run MakeRoot. In other words, there are two threadlets at the destination, one from the viewer and one from the origin region, waiting for each other to do the right thing. That makes it safe to close the agent at the origin upon return of the Update call without having to wait for callback, because we are absolutely sure that the viewer knows it is in th new region. Note also that in the V1 protocol, the destination was getting UseCircuitCode from the viewer twice -- once on EstablishAgentCommunication and then again on TeleportFinish. The second UCC was being ignored, but it shows how we were not following the expected steps...
2013-07-23Correct issue where the last instance of a sampled stat was shown 3x larger ↵Justin Clark-Casey (justincc)1-1/+2
than it should have been (though internal use was correct)

well as the average. This is somewhat cryptic at the moment, need to improve documentation.
2013-07-21EDIT BEAMS!!! They had been missing from OpenSim since ever. Thanks to ↵Diva Canto1-1/+1
lkalif for telling me how to route the information. The viewer effect is under the distance filter, so only avatars with cameras < 10m away see the beams.
2013-07-21Manage AgentUpdates more sanely:Diva Canto1-0/+2
- The existing event to scene has been split into 2: OnAgentUpdate and OnAgentCameraUpdate, to better reflect the two types of updates that the viewer sends. We can run one without the other, which is what happens when the avie is still but the user is camming around - Added thresholds (as opposed to equality) to determine whether the update is significant or not. I thin these thresholds are ok, but we can play with them later - Ignore updates of HeadRotation, which were problematic and aren't being used up stream

2013-07-17Didn't mean to commit this change in BlockingQueue.csDiva Canto1-1/+1
2013-07-17Cleared up much confusion in PollServiceRequestManager. Here's the history:Diva Canto3-49/+36
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.
2013-07-16minor: Add warning method doc about possibly inconsistent results returned ↵Justin Clark-Casey (justincc)1-1/+19
from BlockingQueue.Contains(), Count() and GetQueueArray()
2013-07-16Revert "Revert "MSDN documentation is unclear about whether exiting a lock() ↵Justin Clark-Casey (justincc)1-5/+8
block will trigger a Monitor.Wait() to exit, so avoid some locks that don't actually affect the state of the internal queues in the BlockingQueue class."" This reverts commit 21a09ad3ad42b24bce4fc04c6bcd6f7d9a80af08. After more analysis and discussion, it is apparant that the Count(), Contains() and GetQueueArray() cannot be made thread-safe anyway without external locking And this change appears to have a positive impact on performance. I still believe that Monitor.Exit() will not release any thread for Monitor.Wait(), as per http://msdn.microsoft.com/en-gb/library/vstudio/system.threading.monitor.exit%28v=vs.100%29.aspx so this should in theory make no difference, though mono implementation issues could possibly be coming into play.
2013-07-16Revert "MSDN documentation is unclear about whether exiting a lock() block ↵Justin Clark-Casey (justincc)1-8/+5
will trigger a Monitor.Wait() to exit, so avoid some locks that don't actually affect the state of the internal queues in the BlockingQueue class." This reverts commit 42e2a0d66eaa7e322bce817e9e2cc9a288de167b Reverting because unfortunately this introduces race conditions because Contains(), Count() and GetQueueArray() may now end up returning the wrong result if another thread performs a simultaneous update on m_queue. Code such as PollServiceRequestManager.Stop() relies on the count being correct otherwise a request may be lost. Also, though some of the internal queue methods do not affect state, they are not thread-safe and could return the wrong result generating the same problem lock() generates Monitor.Enter() and Monitor.Exit() under the covers. Monitor.Exit() does not cause Monitor.Wait() to exist, only Pulse() and PulseAll() will do this Reverted with agreement.

2013-07-15Add request received/handling stats for caps which are served by http poll ↵Justin Clark-Casey (justincc)5-51/+70
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.

returned 499 and the exception message in the http_response event rather than the actual response code and body.

2013-07-08Add "show caps stats by user" and "show caps stats by cap" console commands ↵Justin Clark-Casey (justincc)7-16/+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
