Update the git hooks and the CI workflow to ResearchHarness 4e4b534 - #42
This PR installs the current generated git hooks and CI workflow of the ResearchHarness, commit 4e4b534. Two changes reach this repository.
The downgrade job resolves the root and test projects together
.github/workflows/CI.yml (ResearchHarness #157): the Downgrade job runs julia-downgrade-compat with projects: ., test. It resolves Project.toml and test/Project.toml into one manifest, at their lower bounds, and forcedeps checks the lower bounds of both.
Before, it resolved the root project alone, so each indirect dependency came in at its newest version, and the test run, which keeps that manifest, could not add a test-only dependency that caps it. Two forms of this failure appear across these packages: DocStringExtensions 0.10.2 against Documenter 1.19, and CEnum 1.0.0 against CairoMakie or Metal.
The job stays advisory, and the required checks do not change. A lower bound in test/Project.toml that cannot be reached now turns the job red, with forcedeps check failed: Some test dependencies did not resolve to their lower bounds. Such a bound is fixed on this branch before the merge.
The git hooks take the fixes of the hook review
.githooks/pre-commit.jl and .githooks/pre-push.jl (ResearchHarness #156):
A package name that is not a Julia identifier is refused with one line, before any code is built from it.
A Project.toml is a package only with both a name and a uuid; otherwise pre-commit runs no load test, and pre-push runs test/runtests.jl.
An interrupted push waits until the suite's process group is gone, and kills it at the grace time.
A failed load report starts at its first ERROR: line, and the error refusals print the location line.
The staged paths reach fatou lint after --, and a fatou failure with no finding line is reported as a failure of fatou; the lint stage stays advisory.
Files
The six files are byte-identical to the ResearchHarness at 4e4b534, as harness githooks --apply and harness workflows --apply install them: CI.yml, .githooks/pre-commit, pre-commit.jl, pre-push, pre-push.jl and test-layout.jl. Only pre-commit and pre-push are executable. Files that already match do not appear in the diff. No package source changes.
Lower bounds for the merged downgrade check
The merged resolve on Julia 1.12 failed on StaticArrays, and the tests at the floors failed in Aqua. test/Project.toml changes as follows; the root Project.toml floors resolve as they are.
StaticArrays 1 → 1.5.17: every release before 1.5.17 caps julia at 1.10 in the General registry, so the resolve gave StaticArrays resolved to 1.5.17 but lower bound is 1.0.0.
JET gets the compat entry 0.10, 0.11, 0.12, 0.13. It had none, so the merged resolve picked the oldest release that installs; 0.10.0 is the first JET release for Julia 1.12, and the JET tests pass there.
Aqua 0.8 → 0.8.14: at 0.8.13 the piracy test errors with FieldError: type Core.TypeName has no field mt on Julia 1.12; 0.8.14 adapts to the method table changes of Julia 1.12. At 0.8.0 the ambiguity and persistent-task tests also failed.
With these bounds the resolve and the forcedeps check pass, and the whole suite passes at the floors on Julia 1.12. CHANGELOG.md has the entry under [Unreleased].
Merge of main
The last commit merges main, which conflicted in test/Project.toml: main adds the test dependency ForwardDiff with the bound "1", and this branch adds the JET bound, so both stay. The text merge also put this branch's CHANGELOG entry into the released [0.3.5] section; it moves to a new [Unreleased] section above [0.4.0]. On Julia 1.12.7 the downgrade resolve of the merged tree passes, with ForwardDiff at its floor 1.0.0, and the whole suite passes at the floors.
Summary by CodeRabbit
Bug Fixes
Commit and push checks now handle timeouts and interruptions more reliably and provide clearer error details.
Package validation checks for a valid project name and UUID; invalid metadata causes the commit check to fail.
Lint findings and package load errors are reported more clearly. Advisory checks are skipped when linting fails without identifiable findings.
Chores
Compatibility testing now resolves direct dependencies from both the root and test projects together and tests on Julia 1.12.
Updated test dependency compatibility requirements for Aqua, JET, and StaticArrays.
The downgrade job resolves the root and test projects together (projects: ., test), and the hooks take the fixes of the hook review.

Walkthrough
The hooks change process handling, diagnostics, lint result interpretation, package validation, and load-test reporting. The CI downgrade job resolves the root and test projects together. Test dependency compatibility bounds and the Unreleased changelog also change.
Changes: Hook updates
Layer / File(s)
Summary
Process lifecycle and interruption .githooks/pre-commit.jl, .githooks/pre-push.jl
The pre-commit timeout path uses a monotonic clock and closes its SIGKILL timer after waiting. The pre-push test runner defers interrupts during startup and waits for the process and process group after interruption.
Error and lint reporting .githooks/pre-commit.jl, .githooks/pre-push.jl
Error headlines include up to two lines of error output and parse-error details. The lint stage passes staged paths after -- and counts only concise-format finding lines after a nonzero exit.
Package validation and load reporting .githooks/pre-commit.jl, .githooks/pre-push.jl
Both hooks require name and uuid and validate package names as Julia identifiers. The pre-commit hook reports up to 20 lines starting at ERROR:, or at the first line if none exists.
Downgrade checks

Summary
Combined project resolution and test bounds .github/workflows/CI.yml, test/Project.toml, CHANGELOG.md
The downgrade action resolves the root and test projects together. Test dependency compatibility bounds change, and the changelog records the lower-bound CI run and dependency details.

observed — CHANGELOG.md (service) was modified; 1 changed file maps to changed impact.
observed — test (service) was modified; 1 changed file maps to changed impact.
Before / after behavior
observed — Modified behavior in CHANGELOG.md: Added the Unreleased “Changed” entry documenting the Julia 1.12 lower-bound CI test run and the StaticArrays, JET, and Aqua test-dependency compatibility changes.
observed — Modified behavior in test/Project.toml: The Aqua compatibility lower bound changes from 0.8 to 0.8.14; JET gains a compatibility range of 0.10, 0.11, 0.12, 0.13; and the StaticArrays lower bound changes from 1 to 1.5.17. Documenter, FFTA, and SafeTestsets compatibility entries are unchanged.
observed — Modified behavior in .github/workflows/CI.yml: The downgrade-job comments now describe checking lower bounds for direct dependencies in both the root and test projects, resolving them together, and stopping when test/Project.toml is missing. This replaces the previous description, which said test-project floors were not checked.
observed — Modified behavior in .github/workflows/CI.yml: The downgrade action now resolves ., test together instead of leaving projects unset, including the test project in its compatibility downgrade run.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Bound the wait for a terminated process group.
If an interrupted suite leaves an orphaned test process as a zombie, signal(0) can continue to report that the group exists. SIGKILL cannot remove a zombie. When its new parent does not reap it, this loop never ends, so the push remains blocked even after the grace period and further interrupts. Stop waiting once no live group members remain, or apply a final bounded wait and report incomplete cleanup. (man7.org)

The Downgrade job resolves Project.toml and test/Project.toml together at
their lower bounds on Julia 1.12. StaticArrays 1 -> 1.5.17 (earlier releases
cap julia at 1.10), JET gets the compat entry "0.10, 0.11, 0.12, 0.13"
(0.10.0 is the first release for Julia 1.12), and Aqua 0.8 -> 0.8.14 (0.8.13
and earlier error in the piracy test on Julia 1.12).

After an interrupt, pre-push waits at most 10 s past its SIGKILL for the suite's process group, and further interrupts are deferred until it exits. The time box of pre-commit measures its grace on the monotonic clock. A parse error's refusal names the parser's reason, and a Project.toml with a name and no uuid says that no load test runs. These are the fixes of the review of this pull request.

.githooks/pre-commit.jl:82-90 Major · Stability & Availability · Quick win
Synchronize the SIGKILL callback before releasing the group ID.
close(killer[]) does not wait for an expired callback. The callback can therefore call signal_group(group, Base.SIGKILL) after delete!(BOXED, group) and after run_boxed returns. A reused group ID can make that signal terminate an unrelated process group, which can disrupt the pre-commit workflow or other local processes. Guard the callback and cleanup with a lock, cancel queued callbacks during cleanup, and issue the fallback SIGKILL while holding the lock.
Suggested fix
stopped = Ref{Union{Nothing, Float64}}(nothing)
killer = Ref{Union{Nothing, Timer}}(nothing)
+ killer_lock = ReentrantLock()+ killer_cancelled = Ref(false)
# `stopped` is set last, so the box finds the SIGKILL timer whenever it sees the stop.
stop = Timer(seconds) do _
- killer[] = Timer(_ -> signal_group(group, Base.SIGKILL), 5)+ killer[] = Timer(_ -> begin+ lock(killer_lock)+ try+ if !killer_cancelled[]+ signal_group(group, Base.SIGKILL)+ end+ finally+ unlock(killer_lock)+ end+ end, 5)
signal_group(group, Base.SIGTERM)

Bound the process-group wait after SIGKILL.
When p has exited and an unreaped zombie keeps signal(0) == 0, the current loop sleeps forever. wait(p) cannot reap that descendant. Track that the timer sent SIGKILL and stop the group poll after that point, while preserving the wait for live descendants before the grace period.
Suggested fix
+ killed = Ref(false)+ killer = Timer(_ -> begin+ signal(Base.SIGKILL)+ killed[] = true+ end, grace)- killer = Timer(_ -> signal(Base.SIGKILL), grace)
# `kill(-group, 0)` fails once the group is gone, and on macOS also for a group
# whose only processes are zombies that nobody has reaped yet.
