From 0621b14a7effdb245d5f88e976b8b8f52fd1d46c Mon Sep 17 00:00:00 2001 From: ChrisRackauckas Date: Wed, 12 Nov 2025 08:45:08 -0500 Subject: [PATCH 01/13] Fix type inference issue with LinearVerbosity keyword constructor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes a type stability issue in the `LinearVerbosity` keyword argument constructor that was causing type inference failures in `LinearCache` initialization. Root Cause: The keyword argument constructor for `LinearVerbosity` was not type-stable because `values(final_args)...` produces different types depending on runtime kwargs, preventing the compiler from inferring a concrete type. Solution: 1. Added a fast path in the keyword constructor that returns early with a concrete type when all arguments are `nothing` (the default case) 2. Added `Base.@constprop :aggressive` to `__init` to help the compiler propagate the default `verbose=true` constant through the call chain This ensures that `LinearVerbosity()` with no arguments is type-stable, which is the common case when users rely on defaults. Changes: - src/verbosity.jl: Added fast path for default construction - src/common.jl: Added @constprop :aggressive to __init function Fixes the CI error: ``` return type LinearCache{..., LinearVerbosity{...}, ...} does not match inferred return type LinearCache{..., _A<:LinearVerbosity, ...} ``` All tests pass with this change. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/common.jl | 4 ++-- src/verbosity.jl | 22 ++++++++++++++++++++++ 2 files changed, 24 insertions(+), 2 deletions(-) diff --git a/src/common.jl b/src/common.jl index 3fdf43cc5..840d328f0 100644 --- a/src/common.jl +++ b/src/common.jl @@ -261,7 +261,7 @@ function SciMLBase.init(prob::LinearProblem, alg::SciMLLinearSolveAlgorithm, arg __init(prob, alg, args...; kwargs...) end -function __init(prob::LinearProblem, alg::SciMLLinearSolveAlgorithm, +Base.@constprop :aggressive function __init(prob::LinearProblem, alg::SciMLLinearSolveAlgorithm, args...; alias = LinearAliasSpecifier(), abstol = default_tol(real(eltype(prob.b))), @@ -328,7 +328,7 @@ function __init(prob::LinearProblem, alg::SciMLLinearSolveAlgorithm, # @warn "Using `true` or `false` for `verbose` is being deprecated.
