Jail fails to load after creating a new jail with cells, then restarting the server. #41

ghost · 2015-01-27T22:23:24Z

Looks like jail is returning an error when it tries to load the flatfile. I've included the error below.

I basically deleted the data.yml file, started up the live server, then created the jail for a fresh file. I then copied the files in the folder over to my local test server, which is an identical copy of my live server, and started it up. The error showed up when I checked the logs to see if the jail loaded successfully.

The text was updated successfully, but these errors were encountered:

Which version of the plugin are you using? More specifically, which build?

Build #154

ghost · 2015-01-27T22:42:11Z

it looks to me like its the same problem we were having with #40. When the server starts the load state for Jail, it attempts to read the data.yml which isn't being formatted correctly, and it throws the error.

graywolf336 · 2015-01-27T23:01:08Z

Can you provide the data.yml?

ghost · 2015-01-27T23:08:46Z

yeah, give me a couple of secs to send it from the live server to my mediafire

ghost · 2015-01-27T23:10:48Z

graywolf336 · 2015-01-27T23:25:38Z

Can you turn debugging on (/togglejaildebug or edit the config) and try with build 155? I just need the debugging output when loading it on your server.

ghost · 2015-01-27T23:29:08Z

ok, give me a few moments

graywolf336 · 2015-01-27T23:31:23Z

Thanks

ghost · 2015-01-27T23:34:51Z

ok, this is pretty much all I got when I started it up with the data.yml from the live server.

Can you provide the logs before that?

ghost · 2015-01-27T23:36:35Z

I can give you the whole log from startup if thats what you want.

graywolf336 · 2015-01-27T23:37:00Z

Just the lines from where Jail starts to load until that error is all I really need.

ghost · 2015-01-27T23:38:31Z

that was all I got from the log, here is the entire log if you arent sure:

ghost · 2015-01-27T23:40:17Z

oh I see it now! Its really hard to see the debug data!

graywolf336 · 2015-01-27T23:40:50Z

Okay, you can disable debugging and download the latest build...if you don't mind.

ghost · 2015-01-27T23:41:50Z

of course I don't mind, I'm helping someone out! :)

ghost · 2015-01-27T23:45:52Z

graywolf336 · 2015-01-27T23:46:34Z

Okay, so you don't have a world Void on your test server do you?

ghost · 2015-01-27T23:47:10Z

I do have a world called Void, its a exact duplicate of my live server.

ghost · 2015-01-27T23:47:57Z

hmm, I wonder if its a problem with jail talking to worlds generated by Multiverse?

ghost · 2015-01-27T23:49:02Z

let me try this on my barebones world. It doesnt have any plugins installed.

graywolf336 · 2015-01-27T23:50:25Z

Yes it is, since those worlds aren't loaded yet even though the Jail plugin is set to load POSTWORLD. Let me set the plugin to load after Multiverse.

ghost · 2015-01-27T23:51:12Z

ok, then we'll try this again, lol

graywolf336 · 2015-01-27T23:53:52Z

Let's try after this build. I just changed up a few things. First, it will load the Jails which their world is disabled/not loaded but the Jail will be disabled. Second, it will load after multiverse.

ghost · 2015-01-27T23:54:34Z

ok, sounds good.

ghost · 2015-01-27T23:58:28Z

the new build is 158 correct?

graywolf336 · 2015-01-27T23:58:51Z

Correct

ghost · 2015-01-28T00:00:20Z

Eh, it won't work. Hang on, forgot Multiverse changed their name to Multiverse-Core. And heh, okay that's funny.

ghost · 2015-01-28T00:01:56Z

It happens to everyone, its just one of those long restless nights :)

graywolf336 · 2015-01-28T00:09:56Z

Here we go, in theory it should work just fine...but let's see let you test it first. 😝

graywolf336 · 2015-01-28T00:22:03Z

Did that work or have you yet to try it @madisonofccs?

ghost · 2015-01-28T00:24:05Z

oh! sorry, was doing laundry, lol! let me get that build

graywolf336 · 2015-01-28T00:24:55Z

Oh that's for sure more important! 😜

ghost · 2015-01-28T00:27:17Z

looks like you squished that bug! Just have to figure out how to get rid of the extra "jail" thats being generated :)

graywolf336 · 2015-01-28T00:28:37Z

Yeah...so are you able to replicate this extra thing 100% of the time?

ghost · 2015-01-28T00:30:18Z

yeah, it happens whenever cells are created in the jail, once you do /jail stop it writes that line into data.yml. It might have something to do with how cells are being written into the flatfile.

I can try it with the new build, and see if it does it this time.

graywolf336 · 2015-01-28T00:37:58Z

Huh, interesting...wonder where I've messed up to cause this.

ghost · 2015-01-28T00:38:28Z

im testing with the build 159 to see if it creates it again.

graywolf336 · 2015-01-28T00:38:44Z

I just pushed another change, can you try build 160?

ghost · 2015-01-28T00:40:13Z

well, the test with 159 didn't generate the additional "jail", it looks like whatever you did to kill this bug killed that one at the same time

graywolf336 · 2015-01-28T00:42:43Z

How many cells did you create? Cause when testing I only created one cell..

ghost · 2015-01-28T00:43:02Z

I did the test with 159 creating a new jail called Foo, and giving it 3 cells. When I was done I did /jail stop, and then stopped the server.

graywolf336 · 2015-01-28T00:44:08Z

Well yay then! 😄 Thanks for all your help!

ghost · 2015-01-28T00:44:27Z

its not a problem, we make a very good team!

graywolf336 · 2015-01-28T00:45:09Z

Try to break something else now so I can fix something else haha

ghost · 2015-01-28T00:45:22Z

if you ever need anyone to test stuff for you, you have my email already, just give me a shout :)

graywolf336 · 2015-01-28T00:45:36Z

Will do, thanks!

ghost · 2015-01-28T00:45:41Z

but...but, it works so good now, I don't want to break it again :(

graywolf336 · 2015-01-28T00:46:37Z

Fair enough :)

ghost · 2015-01-28T00:49:11Z

well, I suppose this is goodbye for now, until I break something again :). You have a good night, and take a break!

graywolf336 · 2015-01-28T00:49:59Z

Sounds good to me, I'll be taking a break soon to grab something to eat. 🍔 Thanks again for your help!

ghost · 2015-01-28T00:53:05Z

no problem :) have a good one!
