Additional context

This adds JET test_package https://aviatesk.github.io/JET.jl/dev/jetanalysis/#JET.test_package in the typo mode to catch typos in every subpackage.

#2663

Can you also do a full Aqua QA test?

[gdalle]

Note that you should probably be careful with JET versioning, for instance JET.test_package is not yet fully supported by JET v0.10 (see https://github.com/aviatesk/JET.jl/releases/tag/v0.10.0)

[jClugstor]

Many of these are legitimate JET/Aqua failures. Adding these tests without taking care of those issues (if we can) will add a lot of noise when looking at test failures. I can disable the failing tests for each package though to get it set up.

[oscardssmith]

IMO it's probably at least worth a try to fix the issues.

[ChrisRackauckas]

Do the same as what was done for the other repos. Cut it down to subsets, disable what will take too much time for now and file issues on those, but get what we can https://github.com/SciML/ModelingToolkit.jl/pull/2364/files#diff-77acaaefd44e4d00398e2700bc87be028acc6625d6c01c480214e2b992929c0aR3

Jet complains about DAECache not being defined in OrdinaryDiffEqCore, and I can't find any reference to it besides here: https://github.com/SciML/OrdinaryDiffEq.jl/blob/550948230a176ff428875d66356be600e5a59988/lib/OrdinaryDiffEqCore/src/solve.jl#L500C11-L500C33. Where is DAECache defined?

[oscardssmith]

nowhere! this is the fun part about JET. It catches your totally broken code.

[jClugstor]

I'm guessing there are no tests with recompile_flag == false and !(_alg isa OrdinaryDiffEqAlgorithm). Is that just a really uncommon scenario?

[oscardssmith]

both halves of that are unlikely yeah.

[jClugstor]

Most of the failures are from the pre tests since JET 0.9 doesn't work on Julia 1.12. Is there a nice way to specify that for Julia 1.12 we should use Jet 0.10? Or should I just turn off the JET tests based on the VERSION ?

[oscardssmith]

Suggested change

	JET = "0.9.18"
	JET = "0.9.18, 0.10"

This should support Julia 1.12

[jClugstor]

I thought about that but wouldn't that make it always use JET 0.10, unless JET has a compat restriction for Julia?

[gdalle]

Keep in mind that JET 0.10 is marketed as experimental, especially for test_package

[jClugstor]

This just uses it for typos, so hopefully that would be fine. Anyways, it doesn't work because it needs Julia 1.12.0-beta1.11, but pre only uses Julia 1.12.0-beta1. Very cool.

[oscardssmith]

It's `JET's job to provide appropriate compats (and I believe it does so).

Julia 1.12.0-beta1.11, but pre only uses Julia 1.12.0-beta1. Very cool.

never mind. That sounds like a JET bug...

[oscardssmith]

no

[oscardssmith]

my buest guess is there's a missing comma?

[jClugstor]

It does ask you to use a specific branch at https://github.com/aviatesk/JET.jl/blob/master/CHANGELOG.md#0103:
"However, to use JET v0.10.3, you need to use Julia version v"1.12.0-beta1.11" or later. As of April 19, 2025, you need to build Julia from JuliaLang/julia#58009 for using this 1.12 beta version."

[oscardssmith]

yeah that's fine. If you look at https://github.com/aviatesk/JET.jl/blob/v0.10.4/Project.toml it shows that the minimum Julia compat for JET@1.10 is Julia@1.12

[jClugstor]

Ok, so probably just a typo there. The real issue is that test_package isn't available in JET 0.10.4, even though the changelog says it should be.
