`convert` method for `Any` is not ideal

[JeffBezanson]

These methods:

Base.convert(::Type{Any}, x::CatValue) = x
Base.convert(::Type{S}, x::T) where {S, T <: CatValue} =
    T <: S ? x : convert(S, get(x))

currently cause a lot of recompilation, since they involve converting to Any (which is very common) or potentially many other types. Fortunately this is not a large component of load time from what I can tell, but it would still be nice if we can live without these methods somehow.

[nalimilan]

Yes, but how? The problem is that CategoricalValue may wrap any type, so we don't know in advance what conversions might be possible.

[bkamins]

@nalimilan - we could define convert methods for standard types that are normally expected to be potentially by default.

Then we can keep a dictionary of special types and dynamically add a convert method only if a CategoricalArray with such a type is created the first time this happens. This would add a small overhead to array creation for non-standard types, but I think it is not that bad (as in practice it will happen very rarely)

[JeffBezanson]

IIUC, I don't think that would work very well since the dynamically-added method would not be callable in the current world age.

Now, this might just be my opinion and we might have to agree to disagree, but I find CategoricalValue fundamentally flawed. A CategoricalValue version of "x" compares equal to "x" and can be freely converted to it, and yet it does not do ordered comparisons the same as "x". On the one hand, it is trying to be the same as "x", but on the other hand the association with the pool is apparently so important that it can't be just "x". I believe it is best to pick one or the other --- either just another way to store "x" (e.g. PooledArrays), or a truly distinct data type.

[bkamins]

IIUC, I don't think that would work very well since the dynamically-added method would not be callable in the current world age.

I guess you understand it correctly :) and now after thinking about it I agree that it would be just bad as in the current world age another method would be called (the one that would get dispatched to before the new definition were added) which could lead to surprising errors.

Actually according to @snoopr invalidations are caused by the similar methods, not by convert nor ==. This is after removing all definitions in deprecated.jl (which cause lots of invalidations), in a clean Julia master session:

These similar methods are problematic anyway as noted at JuliaLang/julia#36106.

@JeffBezanson Do you think there would be a solution so that collect returns a CategoricalArray when an iterator returns CategoricalValue objects, without causing lots of invalidations? I mentioned some options at JuliaLang/julia#36106. Also, do you think it's a spurious result that convert doesn't appear in the list of invalidations spotted by SnoopCompile?

@nalimilan - thank you for taking time and looking into it as it requires a lot of work and seemingly does not improve anything on user-visible side (except compilation times of course 😄).

[nalimilan]

It looks like a lot of these invalidations could be avoided if the compiler got smarter. For example, the last (and worst) similar method gives this:

julia> show(trees[end].backedges[end])
MethodInstance for similar(::Type{Vector{_A}} where _A, ::Tuple{Int64}) (464 children)
 MethodInstance for similar(::Type{Vector{_A}} where _A, ::Tuple{Base.OneTo{Int64}}) (463 children)
  MethodInstance for _array_for(::DataType, ::Vector{Tuple}, ::Base.HasShape{1}) (51 children)
   MethodInstance for collect(::Base.Generator{Vector{Tuple},Pkg.PlatformEngines.var"#36#62"}) (48 children)
    MethodInstance for #probe_platform_engines!#14(::Bool, ::typeof(Pkg.PlatformEngines.probe_platform_engines!)) (47 children)
     MethodInstance for probe_platform_engines!() (46 children)
     ⋮
  ⋮
  MethodInstance for _array_for(::Type{T}, ::UnitRange{Int64}, ::Base.HasShape{1}) where T (345 children)
   MethodInstance for collect(::Base.Generator{UnitRange{Int64},_A} where _A) (320 children)
    MethodInstance for _ntuple(::Function, ::Int64) (316 children)
     MethodInstance for ntuple(::Serialization.var"#5#6"{Distributed.ClusterSerializer{Sockets.TCPSocket}}, ::Int64) (32 children)
     ⋮
     MethodInstance for ntuple(::typeof(one), ::Int64) (38 children)
     ⋮
     MethodInstance for ntuple(::LibGit2.var"#2#3", ::Int64) (56 children)
     ⋮
     MethodInstance for ntuple(::Base.var"#481#482"{Vector{SubString{String}}}, ::Int64) (164 children)
     ⋮
    ⋮
   ⋮
  ⋮
 ⋮

But collect(::Base.Generator{Vector{Tuple},Pkg.PlatformEngines.var"#36#62"}) (48 children) shouldn't be affected by the new methods AFAICT, since a Vector{Tuple} isn't Array{Union{Missing, CategoricalValue{...}}.

Then there are all the ntuple calls. I'm not sure why they are invalidated, as _ntuple itself is marked with @noinline_meta so shouldn't it act as a barrier which is known to return ::Tuple{Vararg{Int64,N} where N} and prevents further invalidation of dozens of methods?

Even without this, _ntuple calls collect on a generator via ([f(i) for i = 1:n]...,), and 1:n shouldn't be affected by the new similar methods either as its type is always UnitRange{Int}. (I must say I'm not sure whether collect(::Base.Generator{UnitRange{Int64},_A} where _A) (320 children) refers to a method which has been generated for a concrete type _A or assuming that _A is Any; @code_typed _Base.ntuple(one, 1) indicates that the generator is inferred as Core.PartialStruct(Base.Generator{UnitRange{Int64},typeof(one)}, Any[Core.Const(one, false), Core.PartialStruct(UnitRange{Int64}, Any[Core.Const(1, false), Int64])])).

Glad to see that folks are looking into CategoricalArrays, it is a standout for invalidations. And glad to hear that you're on your way to deprecating many of the problematic methods.

However, when I run with a very recent Julia build and eliminate loading of the deprecated methods of CategoricalArrays just as you have done, I get this:
