Dev Blog: New Server Config Loader (Json)

https://i.imgur.com/veo8u2g.png

Thanks to the work of Shin Noir (Xackery) from RebuildEQ, we've converted our server config loader from XML to JSON.

This is now live, whenever new binaries are used, world.exe will automatically pull down a config converter before attempting to load the config. This looks something like this:

World will use the new eqemu_config.json effective immediately. All other utilities that were built around loading config variables from XML will have to be adjusted or updated to use the JSON format.

A backup of the old XML config will be located in serverdir/backups/

The Perl MySQL plugin has been updated already: see here
Linux Installer now uses the new .json format
Windows Installer now uses the new .json format
DiscordEQ OOC chat relay built by Shin should have a new release ready for this change: see here

If you find any tools or utilities tied to the old XML format that needs to be changed or adjusted, let us know in this thread and we will make sure that things get adjusted appropriately.

Sorry for an annoying question, lol. I was just curious about the future. If one was using old binaries, (for example, compiled last week),
is anything planned for the future that would interfere with older binaries patching into the public eqemu login server ?
This whole .json thing is something I need to learn about, so just checking for future reference :)

BUG ??
When I ran new binaries, it got this far and just hung there. But in my server directory, I noticed it kept deleting the
eqemu_server.pl file and replacing it. Just kept doing that continuously, (looped) It was just a test box anyways.
I also tried just running the script by itself (without binaries) and got the same thing.

Code:

Pulling down EQEmu Server Maintenance Script (eqemu_server.pl)...

[Update] Script has been updated, updating...

[Install] Installing :: eqemu_server.pl

[Update] No script update necessary...

EDIT - The "new" script works fine with old binaries, but I also noticed, from trying to run it before, it never did
update anything related to json conversion. (no config or anything). I tried both my own compiled new binaries
and the precompiled downloaded ones. Couldn't get past the "hanging" with any new binaries.

I grabbed the "fixed" eqemu_server.pl from gitpull today and works like a charm. Thank You :)

Glad you got it sorted - however if that is happening to other folks I will need to iron out whatever was causing it

No worries :grin:

Smee again :P
Seems to have downloaded, yet, a newer script, but it's spitting out errors. It doesn't do the json conversion for xml
and oddly enough, it's setting a db version for bots, which I don't even have enabled, lol It set the version at 0 in DB.
This is all on a test box that I'm using to help work out bugs, so I can freely wipe the server and redo anytime.

I just ran a conversion using the latest script and latest binaries and it converted just fine, not sure how you're running into that issue.

Are you running your server binaries within the context of the server directory?

Are you doing something different?

I can confirm I also just ran the latest script on a virtual machine that hasn't even been turned on for 6 months. It converted the .xml to .json without issue.

See if server is there. Is it by chance not all lowercase ? e.g. Server?

In reference my other post (see "works like a charm"), the whole server was working perfect without issues. Then tonight, all I did was
run the eqemu_server.pl script (in the server directory), and wanted to check_db_updates. But when I ran the script, it pulled an updated
version and got those errors shown. World won't even run now, so have to find out why. But as I said, I did nothing except run the script
for db updates, like I've been doing for a long time now.

Just to add: I've been trying to get it to convert the config over to json.(again). I have 3 different configs setup on this one box, for test.
One for local, one for lan, and one for public. I was simply trying to get them all (one by one) converted over to json. But deleting the json
config and putting one of those old configs in, it won't convert them now.

This is the reason I "assumed", if I deleted the json config, replace it with another older xml config, it would
convert it over when world was run. Guess I assumed wrong, lol

Here, just to simplify what I am talking about. I put new binaries in the folder. There is an eqemu_config.xml file in there.
I went into folder with a cmd window and run world and see what happens. Even though it "implies" that it is converting
the xml over to json, it doesn't do it. This is all that happens :

Code:

D:\eqemutest>world

For the moment, I can't figure it out yet. My coffee is getting cold, lol

The_Beast - see what Shin posted above

Looks like your XML is malformed or non-standard

If you can paste it to us via pastebin or otherwords with sensitive info redacted we could help point you in a direction

Hahaha, this funny. First of all Shin, sorry, when you said check top line, I thought you meant the json config. But just found out
if your xml config has "special characters" in the server name, the conversion won't work. I removed them and problem solved.

Interesting, but why not just use Lua for config since the server is already being linked against it?
