Troubleshooting a Conflict Between Addons

[aggixx]

Hello, I've been working on a loot distribution addon for my guild over the past... well let's just say a long time, and I've run into an issue with some users saying various other addons they use stop working when my addon is enabled at the same time. These addons always spew LUA errors having to do with Ace3 libraries so I imagine it's some sort of conflict with libraries, but I also know that the client should automatically find the most up to date instance of each library and only use that version for all addons that require it.

I've done some googling on the issue and haven't found much useful other than tickets to other addon projects saying "Your addon conflicts with this addon, please fix" and "(not) fixed!".

My addon is called FALoot and all of the source code can be found here:
https://github.com/aggixx/FALoot

Two examples of the lua errors I've recieved from users can be found here:
http://pastebin.com/uM2w1MMx
http://pastebin.com/wTWHPm6Z

If anyone has any insight on this issue and how to troubleshoot it, I would appreciate it. Thanks!

The first step of troubleshooting any sort of conflict is always getting rid of any leaking globals (especially SETGLOBALs).

I doubt that that's the issue, though. I'm assuming it's something in the custom FALootWindow AceGUI widget, though I am not experienced enough with AceGUI code to find any issue in there.
Looking through the main.lua itself, I'm curious though - why do you even mess with AceGUI in the first place? You only seem to call :Create once in the file's body, and then use the frame reference itself instead of the AceGUI object. In other words, you could simply create the frame in the main.lua (replacing the :Create call) and not bother with AceGUI custom widgets at all.

First off, I understand why SETGLOBAL is generally a bad thing and I've fixed the bid, rank, and winners variables (woops!), but do you mean to imply that the GETGLOBAL actions listed could be considered leaks? How could that sort of thing potentially cause issues?

Regarding the usage of AceGUI: Originally I had the GUI completely custom-coded. A week ago or so I revamped it since I wanted it to look a little cleaner than it did and I planned to do so by using AceGUI (for every element except for the ScrollingTable), but I quickly realized I could achieve the cleanliness I was looking for simply by using the AceGUI "Frame" object and simply attaching my existing GUI elements to it.

So you think the best route to pursue would be to remove dependency on AceGUI altogether and just replicate the functionality of the AceGUI elements I am using? Wouldn't be terribly difficult to just anchor the whole thing to a plain frame and remove the AceGUI components to see if it solves the conflict issues. And then from there, if it did work, it would be worth the effort since it would mostly just be selectively copying the code I need.

1) One addon leaks table "foo".
2) Second addon GETGLOBAL's "foo" (say, because the author meant to use the local "foobar" but made a typo), then does "local t = foo t.key = value".
3) Addon has now modified the leaked table "foo" inadvertedly (because it had a GETGLOBAL).

Besides, they're also bad for performance.

PS: Yes, I'd suggest dropping AceGUI.

Alright, I've redone the GUI to be completely identical without the usage of AceGUI, and the conflicts seem to be gone for at least one of my users! I'll update this thread if I run into issues but for now it seems solved.

Thanks for your help Treeston!
