error on Julia 1.7.0-beta2

[PaulSoderlind]

using JLD
D = Dict("a"=>"Hazel")
save("test.jld","D",D)

gives

error encountered while save FileIO.File{FileIO.DataFormat{:JLD}, String}("test.jld").              

Fatal error:

T.mutable needs to be replaced with ismutabletype now. Similar to here https://github.com/mauro3/SimpleTraits.jl/pull/76/files

Has anyone taken action for this?

[mauro3]

Unlikely, as there is no pull request. It looks like there is just one instance: https://github.com/JuliaIO/JLD.jl/blob/83ea0c5ef7293c78d7d9c8ffdf9ede599b54dc4c/src/jld_types.jl#L311, so it shouldn't be too hard (if that is indeed the only issue). But I just opened a PR in Compat.jl, then I think it should just be a using Compat.

I was about to make a PR changing it manually. It is present in some other places

Do you want to wait for Compat, or manually change it?

[mauro3]

I have nothing to say here... but my take is that if it is just this one thing, then I wouldn't necessarily add the Compat.jl dependency.

[nandoconde]

Here it is #302

Any movement on this?

I'm getting this error when loading a JLD in 1.7, wondering if it's related?

CapturedException(ErrorException("type DataType has no field mutable"), Any[(getproperty at Base.jl:37 [inlined], 1), (h5fieldtype(parent::JLD.JldFile, T::Any, commit::Bool) at jld_types.jl:313, 1)

I've just made a new release with the latest fixes, please check now, should be fixed !
