Alright. I fixed the next thing. Let's see if it's stable this time.

[Skyrunner]

Y'know, I suddenly had a thought. Maybe CC improperly closes file handles... In my reactor control program, I open a file, read the date written in it, then close the file, a lot of times per hour. If the script spams f.open and f.close, maybe java gets confused and improperly handles that thing.

Whenever you start the server up, could you go to my reactor computer and terminate the program, then rm "startup" to see if it helps? It's farfetched, seeing that CCraft has been around for forever and I'm sure someone other than me thrashed the filesystem, but it's worth a shot.

If that actually was ththe cause, I'm going to feel soooo bad about myself for a while...

Wow, here's how I do uptime in my script:

Code: [Select]

local timeOperationTable={
  __sub=function(a,b)
    if not a or not b then return false end
    if b[2]>a[2] then
          return setmetatable({(a[1]-1)-b[1],(a[2]-b[2])%24},timeOperationTable)
        else
          return setmetatable({a[1]-b[1],a[2]-b[2]},timeOperationTable)
        end
  end,
  __tostring=function(t)
    return t[1]..' in-game days, ' .. math.floor(t[2]) ..' hours'
  end
}

Then, with that metatable, I make a table like so:

Code: [Select]

timeStarted={os.day(),os.time()}
setmetatable(timeStarted,timeOperationTable)

And then I show the current uptime like so:

Code: [Select]

term.write('Uptime: ' .. timeOperationTable.__tostring(setmetatable({os.day(),os.time()},timeOperationTable)-timeStarted))
The weird __tostring thing is because computercraft either does or used to handle metatables really stupidly so I had to do that for maximum compatibility.

Of course, the uptime is measured in Minecraft days/hours, but whatever.

[MagmaMcFry]

Good news everyone! The server is running perfectly fine now, it's no longer leaking filehandles. Turns out everything was Skyrunner's fault. Yes, even the broken hard drive. :V

[Remuthra]

Just goes to show, children, don't build towers unless you're a wizard.

[Skyrunner]

Huzzah.
(edit: it might be worth reportigreporting this as a bug to computercraft if it's reproducible. Does anyone know what normally happens if a script does that? I suspect it wouldn't crash the computer.)

Putnam: I have no idea what the heck is going on in that script x.X

I have thought of a way to do uptime better without thrashing the file system though. It involves loading the file only on startup or status change

[Putnam]

os.time() and os.day() give you the current time of day (in Minecraft time) and day since world generation. The metatable makes it something akin to a class. It requires 0 file io because I can subtract one date from another using the metatable (operator overloading).

[Skyrunner]

Does the metatable survive between server reboots, though?

My script used to put the date and time (minecraft) into a file, then read the contents and do math with the current date and time to get real world hours and minutes.

[Putnam]

It only really accounts for current uptime.

You could always do the file i/o only once per boot.

[Skyrunner]

Yes, that's exactly what I was going to change the thing to do.

I am also considering a lazy screen update, where it checks that the reactor status has changed at all before redrawing the screen.

[Putnam]

Screen writing isn't exactly expensive AFAIK, so I just refresh it as often as possible, sometimes even between ticks (my reactor ticks are usually 2 seconds apart). Unless you're doing something weird when writing, I guess....

[Skyrunner]

So... does anyone want a Tier 5 jetplate? My system for making jetplates completely automatically is almost complete, and i have enough material to spare, but nobody to give jetplates to D:

Don't worry about charging, because you can just come near my cliff base or Sky Tower and watch as your levels go up.

[bluejello]

so, dark trilogy updated,  don't know what all changed though.

[Reudh]

so, dark trilogy updated,  don't know what all changed though.

Probably got made even more grindy. In other news, I will be extending the railway to Sky's cliff base, and after that begins the laborious duplication of the line.

[Skyrunner]

I woke up early for once, but sadly there are no people online now, either D:

edit: wow, apparently the Bauble API tracks baubles using user name. My Angel Ring and Runic Shield ring are gone :/

edit2: suddenly 10 second server (as opposed to latency/ping) lag... I'm not entirely sure if it's my fault, or if the internet is just suddenly wonky. I did install a set of IC2 machines, which are infamous for being laggy.
