I had left in a console.log and cfdump output to file. The staging environment didn't like this one bit and laughed at my suggestion of the code being like the Mona Lisa.
So, I wrote ColdFusion Builder extension to check for debug code and called it debugClean. Its now up and downloadable on RIAForge. Full description:
Checks a file or folder for any debug code that should probably be stripped before moving to staging or production.
Looks for ColdFusion tags: - cfdump - writeDump - cflog - writeLog
The tags and functions it looks for can be configured to your taste in the _config.cfm file.
Go get it, install it and only push our production ready code!
