From 4c58303bb7399bc687018261fff4e429107a1b88 Mon Sep 17 00:00:00 2001 From: Claude Code Date: Wed, 7 Jan 2026 15:19:20 -0500 Subject: [PATCH 1/5] Fix Julia 1.12 precompilation error and add JET static analysis tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Changes: - Fix function signature formatting in atsit5.jl interpolation function that caused "UndefVarError: IIP not defined" on Julia 1.12. The multiline type parameter formatting in the callable struct signature was not correctly binding the type parameters from the where clause. Changed to single-line format which works correctly. - Also changed `if !IIP` to `if !isinplace(integ)` to use the accessor function instead of directly referencing the type parameter, consistent with the pattern used in tsit5.jl - Add JET.jl as a test dependency to enable static analysis testing - Add test/jet_tests.jl with type stability tests for all main solvers: - SimpleEuler (OOP and IIP) - SimpleRK4 (OOP and IIP) - SimpleTsit5 (OOP and IIP) - SimpleATsit5 (OOP and IIP) - All JET tests pass, confirming the solvers are type-stable 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- Project.toml | 6 ++-- src/tsit5/atsit5.jl | 17 +++--------- test/jet_tests.jl | 67 +++++++++++++++++++++++++++++++++++++++++++++ test/runtests.jl | 1 + 4 files changed, 76 insertions(+), 15 deletions(-) create mode 100644 test/jet_tests.jl diff --git a/Project.toml b/Project.toml index e345b3b..45a1e7f 100644 --- a/Project.toml +++ b/Project.toml @@ -1,7 +1,7 @@ name = "SimpleDiffEq" uuid = "05bca326-078c-5bf0-a5bf-ce7c7982d7fd" -repo = "https://github.com/SciML/SimpleDiffEq.jl.git" version = "1.12.0" +repo = "https://github.com/SciML/SimpleDiffEq.jl.git" [deps] DiffEqBase = "2b5f629d-d688-5b77-993f-72d75c75574e" @@ -15,6 +15,7 @@ StaticArrays = "90137ffa-7385-5640-81b9-e52037218182" [compat] DiffEqBase = "6.122" ExplicitImports = "1.14.0" +JET = "0.11.3" JLArrays = "0.1, 0.2, 0.3" MuladdMacro = "0.2" OrdinaryDiffEq = "6" @@ -26,10 +27,11 @@ julia = "1.6" [extras] ExplicitImports = "7d51a73a-1435-4ff3-83d9-f097790105c7" +JET = "c3a54625-cd67-489e-a8e7-0a5a0ff4e31b" JLArrays = "27aeb0d3-9eb9-45fb-866b-73c2ecf80fcb" OrdinaryDiffEq = "1dea7af3-3e70-54e6-95c3-0bf5283fa5ed" SafeTestsets = "1bc83da4-3b8d-516f-aca4-4fe02f6d838f" Test = "8dfed614-e22c-5e08-85e1-65c5234f0b40" [targets] -test = ["ExplicitImports", "JLArrays", "OrdinaryDiffEq", "SafeTestsets", "Test"] +test = ["ExplicitImports", "JET", "JLArrays", "OrdinaryDiffEq", "SafeTestsets", "Test"] diff --git a/src/tsit5/atsit5.jl b/src/tsit5/atsit5.jl index 8589812..9834647 100644 --- a/src/tsit5/atsit5.jl +++ b/src/tsit5/atsit5.jl @@ -692,25 +692,16 @@ end # Interpolation ####################################################################################### # Interpolation function, both OOP and IIP -@inline @muladd function ( -
