Description Ian Romanick 2005-08-04 04:33:37 UTC

If the R200_NO_VTXFMT env var is set, the r200 driver will segfault during
context destruction.  The problem is that the env var isn't tested to determine
if r200VtxfmtDestroy should be called.  I suspect that the radeon and r300
drivers will have a similar problem, but I have not verified that yet.

I believe we should do the following two things:

1. Add a flag that is set when r200VtxfmtInit is called.  Use this flag, and
*only* this flag to determine if r200VtxfmtDestroy should be called.

2. Mark all the env vars that are replaced by dri conf as deprecated.  Remove
them in the next release (i.e., X.org 7.1).

Created attachment 3242 [details] [review]
mesa-6.3.2-freebsd.patch

This implements item #1 in the original bug description.

as far as this env var, I'd say skip directly to the end of #2.  It's not
something that normal users are using.

Comment 3 Ian Romanick 2005-08-12 05:48:03 UTC

I removed support for R200_NO_VTXFMT.  Closing as fixed.  We can go through and
gut all the env variables from all the drivers later.

Mass version move, cvs -> git
