5.0.4 Glyph UI Taint


Patch 5.0.4 introduced an annoying bug to deal with.

Blizzard accidentally declared "_" to be global, so if your addon uses "_" as a global it will cause the GlyphUI frame to not work.

It's an easy fix, instead of:

local class
_, class = UnitClass("player")

Just declare _ as a local variable:

local _, class
_, class = UnitClass("player")

or you can achieve it another way using the select method:

local class = select(2, UnitClass("player"))

Using local variable over global variables is good addon practice for a variety of reasons, some of which include speed of access, interactions with other addons/Blizzard UI, and just not polluting the global namespace.

Good news however is that this is already fixed on the beta and should be slated for patch 5.0.5.

Mikk wrote a nice little utility which helps find global leakage in your addons. You can get it from WowAce here.
