Tenaar Feiri Posted February 24, 2014 Share Posted February 24, 2014 Hey! The title pretty much asks my question for me, but I'll just go ahead & repeat it here. Can I detect when a sim is *about* to be restarted using LSL? I'm working on a script that deals with some data & saves it to the object description and an invisible llSetText() to make it easier to have it persist through restarts & such.The script saves the data periodically, but I don't want to accidentally lose any of the information it's currently processing if a restart unexpectedly happens in the middle of its workflow. I know scripts generally just 'pause' when the server's down & resume again afterwards but I don't trust LL's servers to reliably retain my script data.Is there a way my script can notice when the server's going to be restarted or brought down, so it can stop its work & save the data so it can safely resume its operation afterwards?

Qie Niangao Posted February 24, 2014 Share Posted February 24, 2014 Right, there's no such notification to scripts. I'm not sure it would be very useful anyway, especially not for the reason suggested: I know scripts generally just 'pause' when the server's down & resume again afterwards but I don't trust LL's servers to reliably retain my script data. Such data must be stored externally to SL. Storing it in atttributes of an object on a sim is no more reliable than just trusting the script to start again gracefully (and if they differed, I'd trust the script's state more than the object's). If you're recording stuff of significance outside the sim (e.g., financial transactions), then yeah, those need to be stored externally. One reason is that the sim may not restart at the point where it left off; i.e., it may be rolled-back to a previously saved state. As far as the scripts and objects on the sim, everything is internally consistent, but as if a chunk of history never happened. 1 Link to comment Share on other sites More sharing options...
Tenaar Feiri Posted February 24, 2014 Author Share Posted February 24, 2014 That makes sense. The data's not important enough to justify sending it to my ext. server, but at least I know it's not possible to anticipate the restarts! It's a shame we can't trust the object attributes, really. Or the script memory for that matter; I've had scripts randomly reset themselves whenever someone logs in wearing it, without there being a single reset call in the code to begin with, so I learned not to trust that the hard way. In any case, thanks for answering! Appreciate it! Link to comment Share on other sites More sharing options...

Nova Convair Posted February 24, 2014 Share Posted February 24, 2014 Only avatars get the warning message not objects. So the answer is no. You could use a bot. Question is: why? After restart everything is running like b4 the restart. If the server gets a new version there is a rollback between the last backup and the shutdown. A monitor I run showed me in the last year times between a few mins and 2 hours (very rare). So whatever you do, you cant save any information in the sim for the last few minutes. That will be wiped out in a timewarp. You need to save any late data on an external server. Link to comment Share on other sites More sharing options...

I feel you're overlooking the fact that you're trusting the server to pause and resume script execution up to 45 times a second any time the server is going. A script gets a very thin slice of a server frame. And between those slices, they're rolled up like a rug and stashed in a corner. And let's not even get into the hand off that occurs when teleporting to another sim, when you may have to be trusting not only two different servers, but they may be running differing channels of the software...

Timberwoof Lupindo Posted September 9, 2017 Share Posted September 9, 2017 Here's a scenario where this would be useful: I run a sim where people like to stay locked up by RLV. Some like to go to bed and wake up still locked up. If the sim shuts down, they are logged off. If an imminent shim shutdown could be detected, and RLV device could force-teleport to another region. Then it would periodically to see if the sim was back, and then teleport back to it. The sim knows that shutdown is imminent. Some kind of message that scripts could listen to and have a minute to respond to would be useful for this. Link to comment Share on other sites More sharing options...
Lucia Nightfire Posted September 10, 2017 Share Posted September 10, 2017 Neverminding the necroposting, to be blunt, LL isn't going to implement this feature until they do something definitive against no-copy object duplication means. Specifically, remove any trace of rezzed no-copy object data from all sim state saves when said object is deleted, taken/returned to inventory, attached from ground, moved to another region or if the object has an owner change while rezzed, update all sim state save data with the change. Once that deterrent is in place, maybe the llGetEnv() "region_stop_time" as well as the llGetObjectDetails() OBJECT_REZ_TIME constants can finally be implemented. https://jira.secondlife.com/browse/BUG-8426 https://jira.secondlife.com/browse/BUG-9666 1 Link to comment Share on other sites More sharing options...
Iexo Bethune Posted August 3, 2021 Share Posted August 3, 2021 Another scenario where this would be useful: Nuke sirens that go off around the sim when it's about to restart. Every combat sim will want them! Link to comment Share on other sites More sharing options...

Quistess Alpha Posted August 3, 2021 Share Posted August 3, 2021 I'll bite. Usually when a sim shuts down all the viewers put up a blairing warning. It should be possible for the viewer to then relay the warning on a known channel for things to listen to. . . Link to comment Share on other sites More sharing options...

Drake1 Nightfire Posted August 8, 2021 Share Posted August 8, 2021 I will add another snarky response just for Steph. If you look closely at the sim border you can see the Langoliers devouring the past. 2 Link to comment Share on other sites More sharing options...
Gayngel Posted August 16, 2021 Share Posted August 16, 2021 (edited) You can write a check for a sim restart with llRequestSimulatorData before storing your data or processing it: http://wiki.secondlife.com/wiki/LlRequestSimulatorData There is a "stopping" value returned when calling DATA_SIM_STATUS which will tell you if a region is about to stop/shutdown/restart.

OP is talking about detecting the countdown phase, which only happens when there are main agents present, not detecting remotely. llRequestSimulatorData() can't detect that countdown mode. It will still show 'up' status during that time. During 'stopping' all agents in the region have already been disconnected and no scripts are running.
