Add tests provided by Aqua.jl #687
Conversation

I propose to add Aqua.jl to check some ambiguities, etc, in IntervalArithmetic. In doing so, I noticed the following ambiguities (using Julia v1.10.5): method_ambiguity = (_interval_infsup(::Type{T}, x::Union{BareInterval, Interval}, y, d::IntervalArithmetic.Decoration) where T<:Union{AbstractFloat, Rational} @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/construction.jl:472, _interval_infsup(::Type{T}, a, b::Complex, d::IntervalArithmetic.Decoration) where T<:Union{AbstractFloat, Rational} @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/construction.jl:499)
method_ambiguity = (_interval_infsup(::Type{T}, x, y::Union{BareInterval, Interval}, d::IntervalArithmetic.Decoration) where T<:Union{AbstractFloat, Rational} @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/construction.jl:483, _interval_infsup(::Type{T}, a::Complex, b, d::IntervalArithmetic.Decoration) where T<:Union{AbstractFloat, Rational} @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/construction.jl:497)
method_ambiguity = (interval(::Type{T}, a; ...) where T @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/construction.jl:416, interval(a, d::IntervalArithmetic.Decoration; format) @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/construction.jl:420)
method_ambiguity = (union!(::AbstractVector{S}, ::Interval, ::Any, ...) where S @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/real_interface.jl:120, union!(::AbstractVector{S}, ::Any, ::BareInterval, ...) where S @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/real_interface.jl:124)
method_ambiguity = (kwcall(::NamedTuple, ::typeof(interval), ::Type{T}, a) where T @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/construction.jl:416, kwcall(::NamedTuple, ::typeof(interval), a, d::IntervalArithmetic.Decoration) @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/construction.jl:420)
method_ambiguity = (ExactReal(value::T) where T<:Real @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/exact_literals.jl:54, (::Type{T})(x::ExactReal) where T<:Real @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/exact_literals.jl:109)
method_ambiguity = (union!(::AbstractVector{S}, ::BareInterval, ::Any, ...) where S @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/real_interface.jl:120, union!(::AbstractVector{S}, ::Any, ::Interval, ...) where S @ IntervalArithmetic ~/.julia/dev/IntervalArithmetic/src/intervals/real_interface.jl:124)I plan to fix them in this PR... |

Nice! It does not seem so bad? The 6th item on the list is easy to fix, we just need to add ExactReal(x::ExactReal) = xThough I do not know how we can solve item 4 and 7. |
|
To resolve the first two items about _interval_infsup(::Type{T}, a::Complex, b::Union{BareInterval,Interval}, d::Decoration = com) where {T<:NumTypes} =
complex(_interval_infsup(T, real(a), real(b), d), _interval_infsup(T, imag(a), imag(b), d))
_interval_infsup(::Type{T}, a::Union{BareInterval,Interval}, b::Complex, d::Decoration = com) where {T<:NumTypes} =
complex(_interval_infsup(T, real(a), real(b), d), _interval_infsup(T, imag(a), imag(b), d)) |
|
Items 3 and 5 should be fixed by throwing an explicit error, e.g. interval(T::Type, d::Decoration; format::Symbol = :infsup) = throw(MethodError(interval, (T, d))) |
47605eb solved some ambiguities, but induced (construction) errors Co-authored-by: Olivier Hénot <[email protected]>

Thanks a lot for the suggestions @OlivierHnt, they nicely solve most ambiguities. (My solution 47605eb did solve the ambiguities, but triggered other errors, so I'm reverting it.) |

I think we solved all pure-IntervalArithmetic ambiguities. Yet, there seem to be other, seemingly related to ForwardDiff; see here and the next lines: method_ambiguity = (promote_rule(::Type{ForwardDiff.Dual{T, V, N}}, ::Type{R}) where {T, V, N, R<:Real} @ ForwardDiff ~/.julia/packages/ForwardDiff/PcZ48/src/dual.jl:428, promote_rule(::Type{T}, ::Type{Interval{S}}) where {T<:Real, S<:Union{AbstractFloat, Rational}} @ IntervalArithmetic ~/work/IntervalArithmetic.jl/IntervalArithmetic.jl/src/intervals/construction.jl:553)

Why do the tests only error for Julia 1.9? Yes they are all related to ForwardDiff.jl. Maybe it's because we did not extend the functions properly in IntervalArithmeticForwardDiffExt? |
Tests fail in Julia v1.9 because we This has to be changed, certainly, but since the new LTS Julia version is v1.10.5, I think we should also get rid of most conditionals involving
I'll try to have a look on them later, and perhaps add tests for those that yield ambiguities that I cannot solve. |

Not sure if this should return Interval or Dual{T, Interval{IntervalArithmetic.promote_numtype(V, S), N}...?
@OlivierHnt Any ideas?
Same for ExactReal...

Unfortunately I am note familiar with ForwardDiff.jl... My first impulse would be Dual{T, Interval{IntervalArithmetic.promote_numtype(V, S), N}.
Maybe @Kolaru knows about this more? (though I believe he is very busy at the moment with the PhD defence)
There was a problem hiding this comment.
Locally, tests pass (though I do not get the messages on the ambiguities) using Dual{T, Interval{IntervalArithmetic.promote_numtype(V, S), N} too. I thought about this after pushing the commit, and checking the methods defined for Dual's...
