What this does
Adds a centralized sublibrary downgrade CI workflow (
.github/workflows/DowngradeSublibraries.yml) that calls the reusableSciML/.github/.github/workflows/sublibrary-downgrade.yml@v1workflow.The reusable workflow auto-discovers every
lib/*package containing aProject.tomland, for each one, runsjulia-downgrade-compat+julia-buildpkg+julia-runtestonproject: lib/<sub>. This ensures the lower bounds of each sublibrary's[compat]are actually installable and pass tests.It runs on
push/pull_requesttomaster(ignoringdocs/**), with concurrency cancellation on non-master refs.Sublibraries covered (3)
lib/RecursiveArrayToolsArrayPartitionAnyAlllib/RecursiveArrayToolsRaggedArrayslib/RecursiveArrayToolsShorthandConstructorsAll three contain a
test/runtests.jl.skip list
Dependencies excluded from downgrade (in-repo core package + stdlibs):
RecursiveArrayTools, Pkg, TOML, Statistics, LinearAlgebra, SparseArrays, InteractiveUtils, Random, TestRecursiveArrayToolsis the root in-repo package that all three sublibraries depend on, so it should not be downgraded.Config
julia-version: "lts"allow-reresolve: trueprojects/exclude(auto-discover alllib/*).Note
This adds new required-looking status checks (one job per sublibrary). New checks will appear on PRs once merged.
