Here's an issue I've had rants about in my head for the past
2 months almost.

Say I create a mprog on an item or a mob, or a room. Whenever
I save a zone, hotboot, load the zone and said room/obj/mob,
the program for some reason isn't "loaded", thus forcing me
to edit the program, re-save it, and then attempt to activate
the program once more. What's causing this and how do I fix
it? I'm asking here, mainly because I assume anyone else who
used a stock swfote codebase would've had the same issue.

I wanted to get this fixed a while back, but seeing as to how
my mud is still in dev anyway, it wasn't a high priority, but
now it's just really annoying me so I figured I'd fix it.

I'm not familiar with your codebase but can provide you generic steps for debugging your problem.

1. Consider saving a specific type of "prog"
2. Examine the save function. Follow the code and look for the section that would handle the type of "prog" from 1.
3. Most likely, there is some condition not being met which causes the "prog" to be written to storage. Determine why this condition isn't being met. Run in a debugger and put a breakpoint around here, or just add logging and determine code path that way.
4. If the condition is being met, perhaps you have a problem with permissions writing to your store where the mud thinks that it has written but only is denied write privileges.
5. Perhaps there is no problem with recording the "prog" to storage, but there is a problem with loading the "prog" from storage so that it never actually reads it in and re-initializes the "prog". Upon the next hotboot, the mud writes to storage and assumes that there is no "prog" to save anymore. When the mud loads, there is no evidence of a "prog" in storage.

Hope this helps. Code is deterministic and predictable, you can always figure out what's going on if you know the code path you are executing along. Consider the scenarios and it should be easy to figure out what is going wrong. Worst case, you will know what happened. Best case is that you will know what happened and know how to fix it.

is the mprog actually saving to the area file (or wherever it saves), if so, you probably have some kind of issue with your area loading function.

Or whatever loads the mprogs..

Yeah it's definitely saving to the area file. The problem is,
I'm still a new coder and I don't know near enough to
determine where in the hotboot to add checks for loading
mprogs and oprogs, my latest attempt rewarded nothing to my
cause.

I'm using SWFote Fuss, some of which has been modified by me
for my own purposes but none of those changes should've
messed with saving or loading progs in hotboot-- which makes
me assume that the codebase never loaded them in the first
place at all. I was getting curious if there was a code
snipper that was already done by someone else to get this
working correctly, but I'm having some doubts now. (Also
makes me wonder how people get by without having it...)

Okay, I'm posting this link as a method to help anyone else
who also has the same issue. Apparently it's a problem that
lies within the db.c file of the code.

Many thanks to Remcon for the fix on this one! Note that this
is a problem with both SWR and SWFote. I tested it out and it
fixed all my problems.
