I have found a serious bug in reqmuo(3), and a fix in FreeBSD, validated
by regression tests in proj and a hand-written test. The problem exists
in current and 10, and surely in 9 but I haven't checked.
We currently have no remquo test. I've written one, stealing from
tests/lib/libm/t_sin, and it shows some failing output.
I'm about to (assuming each step is ok)
- do a build and then anita run of current with my new test, and
without the fix
- commit the test
- apply the FreeBSD fix locally, and build/anita
- commit the FreeBSD fix
- apply a further fix locally, and build/anita
- commit that
- request pullups of the test and fix to 10
- probably not request pullups to 9, unless someone asks for them,
since 9 is crufty and really everyone on 9 should be upgrading.
- consider remquof and remquol after all this settles
Is this reasonable? It will show an increased failing test for a bit,
but the test really does fail, and my impression is that the xfail
scheme is about keeping known-failing not-getting-fixed tests from
obscuring "we just had a regression", which a few days of this won't do.
(Absent objections, I'll proceed as above.)
