The @turbo compound unary evaluators called the outer operator even when the inner result was nonfinite. Guard operators that cannot be evaluated on nonfinite inputs; keep the unguarded path for operators that can. Co-authored-by: Miles Cranmer <miles.cranmer@gmail.com>
Per review feedback, the name should be specific to LoopVectorization since it only guards @turbo loops. Co-authored-by: Miles Cranmer <miles.cranmer@gmail.com>
- Add tests covering both branches (turbo_can_eval_nonfinite true/false) for all compound binary+unary evaluation paths in the LV extension - Bump LoopVectorization compat floor from 0.12 to 0.12.170 to fix downgrade-compat CI failure (old LV versions crash on Julia 1.12)
- Remove extra blank line flagged by JuliaFormatter - Bump SymbolicUtils compat from 4 to 4.27 (old versions crash on Julia 1.12 with SCALARS undefvar error)
The julia-downgrade-compat action merges main+test projects. Without matching compat entries in test/Project.toml, the test env tries to resolve different versions than the main project, causing 'can not merge projects' on Julia 1.10.

This changes the version from the already released 2.8.0 back to the previously released 2.5.2. Any package build from this commit is therefore indistinguishable by name/version from the old 2.5.2 source and cannot be registered as the new change; it also makes local version comparisons report a regression. Keep the current 2.8.0 version until the normal release bump.

There was a problem hiding this comment.
When EvalContext(early_exit=false) is used, this unconditional replacement changes ordinary operator semantics. For example, the fused log(exp(x1)) path with x1 = 1000.0 produces x_l = Inf; log(Inf) should remain Inf, but this branch now writes NaN. The API explicitly promises that disabling early exit continues computation as usual, so the guard in all four copied paths needs to account for eval_context.early_exit rather than replacing every nonfinite intermediate.

Environments using Optim 1.x with NLSolversBase 7.x can no longer resolve this package after these bounds are narrowed, even though DynamicExpressionsOptimExt.jl still explicitly implements and documents the v7 layout. This silently removes an existing supported integration without any corresponding code incompatibility, so the previous Optim = "1.13.3, 2" and NLSolversBase = "7.10, 8" bounds should remain.

There was a problem hiding this comment.
The preceding downgrade action explicitly processes both . and test, but deleting test/Manifest.toml discards the exact downgraded versions selected for test-only dependencies before julia-runtest constructs its sandbox. Those missing entries are then resolved afresh rather than kept at their compatibility floors, so this job can pass while the declared minimum versions of Aqua, JET, TestItems, and other test-only packages are broken. Avoid the duplicate package-under-test entry without removing the rest of the downgraded test manifest.

Including this file from unittest.jl does not make its own @testitem blocks pass the filename filter in test/runtests.jl, which currently selects only unittest.jl, test_evaluation.jl, test_buffered_evaluation.jl, and test_optim.jl for the main suite. Consequently both newly added nonfinite-guard test items are excluded from normal CI, leaving the changed @turbo paths untested; add test_nonfinite_operator_guard.jl to testitem_suffixes as is already done for the other standalone test-item files.

@MilesCranmerBot why is CI failing? Can you investigate and fix? |
