Console command debug xengine now turns that on.
Also, per orenh, remove the triggers at 1000 and 10000 as they are not
useful now that top scripts works.
Previously the script state was never saved for a !Running script, so upon region restart the script would be Running again.
The use of the 'StayStopped' flag is needed because all scripts are automatically stopped when the region shuts down, but in that case we shouldn't save in their state that they're !Running.
Previously the "Net Time" was reported: only the time actually spent in the script's code. This is not a correct indication of how much load the script places on the simulator, because scripts that change state often or have many events use up a lot of time just in the event handlers, and previously this time wasn't counted.
Notes:
- This metric provides a better indication of which scripts are taking up a lot of CPU (and therefore should be optimized).
- Previously the execution time was reset to 0 in every new measurement period, causing the reported time to fluctuate for no reason. This has been fixed by using a sliding window.
1. Use a Stopwatch (a high-resolution timer)
2. Whenever we start a new measurement period, zero out the total execution time (previously it just kept accumulating)
3. Changed the measurement period from 30 minutes to 30 seconds. This is much more useful in the "Top Scripts" dialog, as it shows currently active scripts
This should also make it less likely that an event will be erroneously posted during a state change by precluding a race condition with a thread calling ScriptInstance.PostEvent()
This takes the AsyncCommandHandler.staticLock.
However, AsyncCommandHandler.DoOneCmdHandlerPass() already holds staticLock and may attempt to take the EventQueue lock via ScriptInstance.PostEvent() in XEngine.CheckListeners()
This is a regression from faaf47a (Fri Jan 16 2015) but not simply reverting that commit since it will reintroduce a race between script removal, backup and event queue manipulating code.
This eliminates pointless work and exceptions when an appdomain is unloaded whilst an attachment script state is persisted.
Adds test for this case.
Relates to http://opensimulator.org/mantis/view.php?id=7407
This was beause the code was finding the script DLL compiled for the source region as everything is in the same appdomain and using this as the location for the destination script state, etc.
This resolves the regression by passing the proper destination separately from the DLL retrieved.
Probably a regression since commit d7b92604 (11 July 2014).
Added regression test for this case.
At least partly addresses http://opensimulator.org/mantis/view.php?id=7278
We have to do this since we can't unload existing DLLs if they're all in the same AppDomain.
But we can still update the underlying DLL which will be used in the next simulator session.
SmartThreadPool code comes from http://www.codeproject.com/Articles/7933/Smart-Thread-Pool
This version implements thread abort (via WorkItem.Cancel(true)), threadpool naming, max thread stack, etc. so we no longer need to manually patch those.
However, two changes have been made to stock 2.2.3.
Major change: WorkItem.Cancel(bool abortExecution) in our version does not succeed if the work item was in progress and thread abort was not specified.
This is to match previous behaviour where we handle co-operative termination via another mechanism rather than checking WorkItem.IsCanceled.
Minor change: Did not add STP's StopWatch implementation as this is only used WinCE and Silverlight and causes a build clash with System.Diagnostics.StopWatch
The reason for updating is to see if this improves http://opensimulator.org/mantis/view.php?id=6557 and http://opensimulator.org/mantis/view.php?id=6586
TimeSpan.Milliseconds is an int64. However, STP casts this to an int (32-bit).
If TimeSpan.MaxValue is given then the casting results in an invalid value for the SDK WaitHandle.WaitAll() call.
This was causing the co-op script termination regression tests to fail on Windows but not Mono 2.10.8 (which is perhaps not strict in the negative values that it accepts).
Solution here is to use the int millisecondsTimeout STP call rather than the TimeSpan one.
This also allows us to more clearly specify Timeout.Infinite rather than TimeSpan.MaxValue
Thanks to Teravus for this spot.
Moves the noise co-op start/stop debug log messages to only display if xengine debug level >= 1
Logs which stop strategy is being used (abort or co-op)
Adjusts some other logging to remove not very useful stuff
This is to eliminate disruption until co-op termination has been well-tested.
In non co-op mode, XEngine will continue to load DLLs of the existing Script class and the new XEngineScript class.
Moving to co-op mode still requires existing script DLL deletion to force recompilation, either manually or by setting DeleteScriptsOnStartup = true for one run.
This change also means that scripts which fail to initialize do not still show up as running scripts.
This involves inserting opensim_reserved_CheckForCoopTermination() calls in lsl -> c# translation at any place where the script could be in a loop with no wait calls.
These places are for, while, do-while, label, user function call and manual event function call.
Call goes through to an XEngineScriptBase which extends ScriptBase.
IEngine is extended to supply necessary engine-specific parent class references and constructor parameters to Compiler.
Unfortunately, since XEngineScriptBase has to be passed WaitHandle in its constructor, older compiled scripts will fail to load with an error on the OpenSim console.
Such scripts will need to be recompiled, either by removing all *.dll files from the bin/ScriptEngines/<region-id> or by setting DeleteScriptsOnStartup = true in [XEngine] for one run.
Automatic recompilation may be implemented in a later commit.
This feature should not yet be used, default remains termination with Thread.Abort() which will work as normal once scripts are recompiled.
This makes use of EventWaitHandles since various web references indicate that Thread.Interrupt() can also cause runtime instability.
If co-op termination is enabled, then termination sets the wait handle instead of waiting for a timeout before possibly aborting the thread.
This allows the script to cleanly terminate if it's in a llSleep/LL function delay or the next time it enters such a wait without any timeout period.
Co-op termination is not yet testable since checking for termination request within loops that never trigger a wait is not yet implemented.
This commit, unlike 1b5c41c, passes the wait handle as an extra parameter through IScript.Initialize() instead of passing IScriptInstance itself.
