For X.org 6.9 / 7.0 I would like to break the existing libGL / DRI driver interface. There is a *LOT* of crap hanging around in both libGL and in the DRI drivers that exists *only* to maintain backwards compatability with older versions of the interface. Since it's crap, I would very much like to flush it.
I'd like to cut this stuff out for 7.0 for several main reasons:
- A major release is a logical time to make breaks like this.
- Bit rot. Sure, we /assume/ libGL and the DRI drivers still actually work with older versions, but how often does it actually get tested?
In fact, we know that they don't work as backwards compatibility was broken in one of the recent 6.8.x releases, wasn't it?
Given that is the case we might be able to take advantage of that and bring forward some of those changes - the old versions don't work anyway so there's absolutely no point keeping the code around for them...
The 6.8.x break was on the server-side *only*. I made some changes in libglx that slightly broke the interface with the DDX. AFAIK, the client-side interfaces /should/ still work. Like I said, though, I don't know that it has been tested...
