MOOs even save the :>active processes (something Cold doesn't do, and I don't know about :>MUSH). :FWIW I save active processes at runtime (ie across crashes). Well, :sorta -- there's some caching and delays on the writes. Upon restart :the machine will resume exactly as of some state minutes before the :crash. Saving the state of everything without saving information about how that state is being changed would kind of defeat the point of saving. I'm more of an event-based model, but I don't actually save the list of pending events. What I do is allow a machine to have an action which is called on a server restart. Similarly there is one called on a shutdown. That allows explicit setup to gracefully resume across shutdown/restart. For crashes, I just go with an old, but consistent, copy of the whole db. That can result in the timing of things changing a bit, but I doubt if its really noticeable, since there are likely to be a lot of things getting "undone" when restarting from a pre-crash snapshot. -- Chris Gray cg#ami-cg,GraySage.Edmonton.AB.CA </PRE> <!--X-Body-of-Message-End--> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <HR> <ul compact><li><strong>Follow-Ups</strong>: <ul> <li><strong><A NAME="00347" HREF="msg00347.html">[MUD-Dev] New Topic: Butthead features</A></strong> <ul compact><li><em>From:</em> Jeff Kesselman <jeffk#tenetwork,com></li></ul> <li><strong><A NAME="00346" HREF="msg00346.html">Re: [MUD-Dev] Persistance/stability</A></strong> <ul compact><li><em>From:</em> Brandon Gillespie <brandon#roguetrader,com></li></ul> </UL></LI></UL> <!--X-Follow-Ups-End--> <!--X-References--> <!--X-References-End--> <!--X-BotPNI--> <UL> <LI>Prev by Date: <STRONG><A HREF="msg00342.html">Re: [MUD-Dev] Virtual Chemistry</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg00344.html">Re: [MUD-Dev] Virtual Chemistry</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg00357.html">Re: [MUD-Dev] Persistance/stability</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg00346.html">Re: [MUD-Dev] Persistance/stability</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="index.html#00343"><STRONG>Date</STRONG></A></LI> <LI><A HREF="thread.html#00343"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> <ul><li>Thread context: <BLOCKQUOTE><UL> <LI><STRONG>Re: [MUD-Dev] Persistance/stability</STRONG>, <EM>(continued)</EM> <ul compact> <LI><strong><A NAME="00314" HREF="msg00314.html">Re: [MUD-Dev] Persistance/stability</A></strong>, Miroslav Silovic <a href="mailto:silovic#mare,zesoi.fer.hr">silovic#mare,zesoi.fer.hr</a>, Thu 31 Jul 1997, 23:19 GMT <UL> <LI><strong><A NAME="00322" HREF="msg00322.html">Re: [MUD-Dev] Persistance/stability</A></strong>, Matt Chatterley <a href="mailto:root#mpc,dyn.ml.org">root#mpc,dyn.ml.org</a>, Fri 01 Aug 1997, 13:21 GMT </LI> <LI><strong><A NAME="00330" HREF="msg00330.html">Re: [MUD-Dev] Persistance/stability</A></strong>, clawrenc <a href="mailto:clawrenc#cup,hp.com">clawrenc#cup,hp.com</a>, Sat 02 Aug 1997, 06:24 GMT </LI> </UL> </LI> <LI><strong><A NAME="00357" HREF="msg00357.html">Re: [MUD-Dev] Persistance/stability</A></strong>, Adam Wiggins <a href="mailto:nightfall#user1,inficad.com">nightfall#user1,inficad.com</a>, Mon 04 Aug 1997, 02:56 GMT </LI> <LI><strong><A NAME="00343" HREF="msg00343.html">Re: [MUD-Dev] Persistance/stability</A></strong>, Chris Gray <a href="mailto:cg#ami-cg,GraySage.Edmonton.AB.CA">cg#ami-cg,GraySage.Edmonton.AB.CA</a>, Sun 03 Aug 1997, 02:19 GMT <UL> <LI><strong><A NAME="00346" HREF="msg00346.html">Re: [MUD-Dev] Persistance/stability</A></strong>, Brandon Gillespie <a href="mailto:brandon#roguetrader,com">brandon#roguetrader,com</a>, Sun 03 Aug 1997, 04:45 GMT </LI> <LI><strong><A NAME="00347" HREF="msg00347.html">[MUD-Dev] New Topic: Butthead features</A></strong>, Jeff Kesselman <a href="mailto:jeffk#tenetwork,com">jeffk#tenetwork,com</a>, Sun 03 Aug 1997, 06:40 GMT <UL> <LI><strong><A NAME="00351" HREF="msg00351.html">Re: [MUD-Dev] New Topic: Butthead features</A></strong>, Matt Chatterley <a href="mailto:root#mpc,dyn.ml.org">root#mpc,dyn.ml.org</a>, Sun 03 Aug 1997, 15:48 GMT <UL> <LI><strong><A NAME="00365" HREF="msg00365.html">Re: [MUD-Dev] New Topic: Butthead features</A></strong>, Jeff Kesselman <a href="mailto:jeffk#tenetwork,com">jeffk#tenetwork,com</a>, Mon 04 Aug 1997, 08:57 GMT </LI> </UL> </LI> </UL> </LI> </UL> </LI> </ul> </LI> </UL></BLOCKQUOTE> </ul> <hr> <center> [ <a href="../">Other Periods</a> | <a href="../../">Other mailing lists</a> | <a href="/search.php3">Search</a> ] </center> <hr> </body> </html>
