I'm looking for a open source projects of a decent size (30K+ LOC) that have a bug tracking system which details the specific changes in the code required for each fix, preferably down to the line number. The project and the bug tracking information would need to be avaliable me to be of any use.
This is for research into various metrics.
Does anyone know of such a project(s)?
A lot of projects put their patches into the bug tracking system, and that's right down to the line number. It's unlikely to be like that for every change ever made, though; core committers don't usually throw their patches into the BTS, they just commit them.
Consider analysing the revision control history instead. If you can explain exactly what question you're trying to answer, perhaps people can give more exact answers, too.
