What exactly will happen to our scripts when Mono is implemented?

Re: http://secondlife.blogs.com/babbage/2005/08/second_life_in_.htmlI'm not real clear on how the transition will work. What will happen to the data and stack segments when our scripts are "recompiled from LSL source to run on the Mono VM"? If they are somehow translated over to work on the new VM, it should be transparent. If they are NOT translated - effectively causing every script to reset - there could be widespread problems. Many scripted objects, such as the DarkLife backpacks mentioned at the blog, would lose their state. There's also the problem of multithreaded applications where one thread (script) expects another to already be running when it starts up. These days I build my stuff to be tolerant of that kind of situation, but I didn't in the past, and I see no reason to believe there aren't plenty of multithreaded apps by other people that could end up restarting improperly or not at all. Inevitably, some of these would be in the hands of customers already, and not easily replaced. If the data and stack segments are left behind during the transition, a lot of extra work (without extra pay, I think) will be made for a lot of people. |

They'll have to spend a few weeks in the hospital and drink a lot of fluids.

Too complicated to worry about. I'll just ignore it until it hits me on the head.

Good questions Huns, I'm curious about this as well.

Probably run faster and not tax the server so much.

Yes, a very good question. Perhaps they could keep the currently running scripts running on the old VM until which time they are recompiled and when they are, swap them over to mono.

Maybe recompile the LSL bytecode into CIL assembly instead of recompiling it from the text source ?
I can't wait to start scripting in C/Python. Will I also be able to use Perl ?

From: Alondria LeFay Yes, a very good question. Perhaps they could keep the currently running scripts running on the old VM until which time they are recompiled and when they are, swap them over to mono. Unfortunately, I think if they do that, then much of the performance benefits will be pointless, as a significant amount of scripts will still be running on the old VM. Think of all of the scripts in all of the shoes, AOs, dance bracelets, vehicles, sex balls with multiple listens, etc. Huns' question is interesting. Are there really that many scripts in world that rely on a constant, persistent state that would be ruined by a recompile? i would think by now, any script requiring that would be offputting it to an external server and not relying on always being in the item itself. If it isn't, it very well should be.

If it isn't, it very well should be. Storing persistent data to an external server and retrieving it in the event of a reset is not trivial. You have to actually have an external server (costs money) and write some kind of database schema and middle tier software (costs time, effort, and specific skills.) XML-RPC is severely hobbled, so you have to put up with the vagaries of email to make it work, at least initially. |
