world age and Julia 1.12 issue #61
Description
I'm not sure if this is a PrecompileTools issue, but it seems to be. In Julia 1.12 I'm getting the following warning when loading a package:
julia> using CellListMap
Info Given CellListMap was explicitly requested, output will be shown live
WARNING: Detected access to binding `CellListMap.Cell` in a world prior to its definition world.
Julia 1.12 has introduced more strict world age semantics for global bindings.
!!! This code may malfunction under Revise.
!!! This code will error in future versions of Julia.
Hint: Add an appropriate `invokelatest` around the access to this binding.
Precompiling CellListMap finished.
4 dependencies successfully precompiled in 11 seconds. 23 already precompiled.
1 dependency had output during precompilation:
┌ CellListMap
│ [Output was shown above]
└ The warning goes away if I remove the precompilation block, which is at the end of the module. A minimal precompile block that triggers the issue is this one:
import PrecompileTools
PrecompileTools.@setup_workload begin
x = [ rand(3) for i in 1:5000 ]
box = Box([50, 50, 50], 10)
PrecompileTools.@compile_workload begin
cl = CellList(x,box)
end
endTo reproduce the issue, just install CellListMap in an empty environment.
