* changing DropSend()'s foreach loop so that it does not copy theDr Scofield2009-06-251-5/+11

* commenting out rather expensive bits of GetClientInfo() --- the onlyDr Scofield2009-06-251-13/+20
| | | | | | | | bit of GetClientInfo that is actually used seems to be userEP as part of the OSSL osGetAgentIP() script function. Now commented are the parts where we serialize and copy out the *entire* packet queue of the client (locking the packet handler in the process).
* more efficient way of checking for already seen packets:Dr Scofield2009-06-251-29/+47
| | | | | | | | | | | - uses Environment.TickCount for all timestamps (instead of more costly Util.UnixTimeSinceEpoch() - takes care of Environment.TickCount overflow (which will happens after 24.8 days of system uptime) - avoids instantiating List copies for each check - gets rid of one lock() invocation - moves calculation of loop invariant variable out of the loop itself
* adding logging statement for receive buffer sizeDr Scofield2009-06-251-0/+2

* - adds the possibility of setting the socket receive buffer sizeDr Scofield2009-06-251-35/+51
| | | | | | | | | | | | option for LLUDPServer. On windows .NET the default socket receive buffer size is 8192 bytes, on recent linux systems it's about 111K. both value can be a bit small for an OpenSim instance serving many clients. The socket receive buffer size can be configured via an OpenSim.ini config option - adds a general catch clause to LLUDPServer.OnReceivedData() to prevent it submerging when an unexpected Exception occurs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change moves texture send processing out of the main packet processing loop and moves it to a timer based processing cycle. Texture packets are sent to the client consistently over time. The timer is discontinued whenever there are no textures to transmit. The behavior of the texture sending mechanism is controlled by three variables in the LLCLient section of the config file: [1] TextureRequestRate (mS) determines how many times per second texture send processing will occur. The default is 100mS. [2] TextureSendLimit determines how many different textures will be considered on each cycle. Textures are selected by priority. The old mechanism specified a value of 10 for this parameter and this is the default [3] TextureDataLimit determines how many packets will be sent for each of the selected textures. The old mechanism specified a value of 5, so this is the default. So the net effect is that TextureSendLimit*TextureDataLimit packets will be sent every TextureRequestRate mS. Once we have gotten a reasonable feeling for how these parameters affect overall processing, it would be nice to autonmically manage these values using information about the current status of the region and network. Note that this also resolves the pathologcal problem that previously existed which was that a seated avatar generated very few in-bound packets (theoretically) and would therefore be the least able to retrieve the images being displayed by a projector script.

* From: Chris Yeoh <yeohc@au1.ibm.com>Dr Scofield2009-05-181-1/+2
| | | | | | | | | | | | | | | | | We've encountered problems with textures never fully downloading and objects not moving or being deleted (from the client's point of view) even when the bandwidth settings on the client have been set very low. This can happen over reasonably lossy links (eg you're on the other side of the world from the server) as the server retries 3 times and then gives up. Whilst its possible to set ReliableIsImportant, this forces the server to keep retrying no matter what which potentially could lead to problems. This patch allows for the setting of MaxReliableResends explicitly (is set to 3 normally) in OpenSim.ini so if you know you will have clients connecting with poor connections you can set it a bit higher (10-15 works quite well even for very poor connections).

* * Implements IP and DNS based ban facilities to OpenSim. Adam Frisby2009-05-111-1/+33
| | | | | | | | | | * User interface is ... primitive at best right now. * Loads bans from bans.txt and region ban DB on startup, bans.txt is in the format of one per line. The following explains how they are read; DNS bans are in the form "somewhere.com" will block ANY matching domain (including "betasomewhere.com", "beta.somewhere.com", "somewhere.com.beta") - make sure to be reasonably specific in DNS bans. IP address bans match on first characters, so, "127.0.0.1" will ban only that address, "127.0.1" will ban "127.0.10.0" but "127.0.1." will ban only the "127.0.1.*" network

Fix the packet handler to play nice with the packet pool. Fix the packet pool. Add data block recycling to the packet pool. Packet pool is now ENABLED by default.
