OptimizationBase (v2) fails to precompile

[tkemmer]

Describe the bug 🐞
Precompilation of OptimizationBase 2.13.0 fails due to duplicated definitions here

Optimization.jl/lib/OptimizationBase/src/solve.jl

Lines 4 to 10 in 59b27be

	struct IncompatibleOptimizerError <: Exception
	err::String
	end
	function Base.showerror(io::IO, e::IncompatibleOptimizerError)
	print(io, e.err)
	end

and

Optimization.jl/lib/OptimizationBase/src/solve.jl

Lines 33 to 39 in 59b27be

	struct IncompatibleOptimizerError <: Exception
	err::String
	end
	function Base.showerror(io::IO, e::IncompatibleOptimizerError)
	print(io, e.err)
	end

Expected behavior
The package should be precompilable.

Minimal Reproducible Example 👇

]precompile OptimizationBase

Additional context

Add any other context about the problem here.

[lazarusA]

Yes, I'm also seeing those even with the latest back port.

[ChrisRackauckas]

Sorry, I really messed up the backport. v2.13.1 should handle it. Ping me if it doesn't since I'll be out and about but I incorporated @sabastianM-c's fix and the precompile fix of removing the duplicate.

[tkemmer]

@ChrisRackauckas Thanks! Precompilation still fails as there seems to be another code duplicate in

Optimization.jl/lib/OptimizationBase/src/solve.jl

Lines 22 to 30 in 4ca0a2e

	struct OptimizerMissingError <: Exception
	alg::Any
	end
	function Base.showerror(io::IO, e::OptimizerMissingError)
	println(io, OPTIMIZER_MISSING_ERROR_MESSAGE)
	print(io, "Chosen Optimizer: ")
	print(e.alg)
	end

and

Optimization.jl/lib/OptimizationBase/src/solve.jl

Lines 176 to 184 in 4ca0a2e

	struct OptimizerMissingError <: Exception
	alg::Any
	end
	function Base.showerror(io::IO, e::OptimizerMissingError)
	println(io, OPTIMIZER_MISSING_ERROR_MESSAGE)
	print(io, "Chosen Optimizer: ")
	print(e.alg)
	end

Removing this part as well finally solved the problem for me locally.

Is that working? I get the same issues here, I'm afraid...

[ChrisRackauckas]

Okay sorry I think I got all of the edge cases this time.

@ChrisRackauckas This (second) code duplication is still present in 2.13.2, preventing precompilation.

[ChrisRackauckas]

oh v2, I handled it on v3 ugh

[ChrisRackauckas]

okay new patch should be good.

[tkemmer]

@ChrisRackauckas Thanks again! Precompilation still fails, I'm afraid...

  ? OptimizationBase

Maybe introduced in 671056e, which would cause a second include("solve.jl") in OptimizationBase.jl if

Optimization.jl/lib/OptimizationBase/src/OptimizationBase.jl

Lines 19 to 21 in ebb0401

	@static if !hasmethod(SciMLBase.__solve, Tuple{OptimizationProblem, SciMLBase.AbstractOptimizationAlgorithm})
	include("solve.jl")
	end

is true? The second include being here:

Optimization.jl/lib/OptimizationBase/src/OptimizationBase.jl

Line 45 in ebb0401

include("solve.jl")

[ChrisRackauckas]

Yes I see what happened. When I cherrypicked the backport, I only got one of the 3 commits I expected 😅 it at least makes sense what happened here... very sorry about that, was so confused why the backport was all messed up.
