| * Update SmartThreadPool to latest version 2.2.3 with a major and minor change.Justin Clark-Casey (justincc)2013-05-011-3/+6
| | | | | | | | | | | | | | | | | | | | 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

| * Use an integer when specifying the XWorkItem wait rather than a TimeSpan to ↵Justin Clark-Casey (justincc)2013-02-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | avoid a Windows casting issue in SmartThreadPool for large TimeSpans. 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.

| * Bump version and assembly version numbers from 0.7.5 to 0.7.6Justin Clark-Casey (justincc)2013-02-051-1/+1
| | | | | | | | | | | | | | | | This is mostly Bluewall's work but I am also bumping the general version number OpenSimulator 0.7.5 remains in the release candidate stage. I'm doing this because master is significantly adding things that will not be in 0.7.5 This update should not cause issues with existing external binary DLLs because our DLLs do not have strong names and so the exact version match requirement is not in force.

| | | | | | | | | | | | | | | | | | continue to generate C# that is functionality identical to historical generation 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | addition to termination on wait. 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.

| | | | | | | | | | | | | | | | | | | | script wait event (llSleep(), etc.) 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.

| | | | | | | | | | | | | | | | pass down IScriptInstance instead. This is to allow the future co-operative script thread terminate feature to detect and act upon termination requests. This splits the assembly and state loading out from the ScriptInstance() constructor to a separate Load() method in order to facilititate continued script logic regression testing.

As with script stop (via llDie()) aborting other scripts event threads, llResetOtherScript() can also abort any current event thread on another script. On mono 2.6, 2.10 and possibly later this may cause locking problems in certain code areas. This commit reuses the recently introduced [XEngine] WaitForEventCompletionOnScriptStop to make this a 1 sec timeout, rather than 0 secs.
