What changed

  • Stage the already-built ProxySQL_GenAI_Plugin.so in the central GenAI build's existing _runtime_libs test handoff.
  • Restore the plugin to plugins/genai/ in the shared AI GCOV consumer before infrastructure startup.
  • Fail explicitly at the producer or consumer boundary when the required plugin is missing.
  • Add a behavior test that executes the real workflow shell steps against temporary handoff trees.

Root cause

The ubuntu24-tap-genai-gcov build successfully linked the GenAI plugin, but plugin staging was guarded by the MySQLX-only matrix condition. CI-ai-g1 and CI-ai-g2 therefore unpacked the build handoff without plugins/genai/ProxySQL_GenAI_Plugin.so and failed before any TAP test ran.

Validation

  • python3 .github/scripts/tests/test-genai-plugin-handoff.py
  • .github/scripts/tests/test-resolve-tap-build-mode.bash
  • PyYAML parsing of ci-builds.yml and ci-ai-gcov.yml
  • git diff --check origin/GH-Actions...HEAD

After this merges into GH-Actions, PR #6083 needs an empty commit so its central build and AI fan-out consume the updated reusable workflows.


Summary by cubic

Fixes CI failures in GenAI TAP shards by handing off the built GenAI plugin from the central GenAI build and restoring it before infrastructure startup. Previously the plugin was built but not staged (gated by a MySQLX-only condition), so shards unpacked without it and failed before any TAP test.

  • Stages plugins/genai/ProxySQL_GenAI_Plugin.so into test/tap/tap/_runtime_libs for -genai builds in ci-builds.yml; fails if the plugin is missing.
  • Restores the plugin in ci-ai-gcov.yml to plugins/genai/ProxySQL_GenAI_Plugin.so and verifies both the binary and plugin before starting infrastructure; fails if missing.
  • Adds .github/scripts/tests/test-genai-plugin-handoff.py to execute the real workflow steps against temp trees, enforcing the producer/consumer contract.
  • Required action after merge: push an empty commit to PR test: verify label-selected TAP ASAN CI #6083 so its central build and shards pick up the updated reusable workflows.

Written for commit 1f77af8. Summary will update on new commits.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds GenAI plugin handoff between build and AI test workflows. Builds stage and verify the plugin in _runtime_libs. AI tests restore and verify it under plugins/genai/. A Python contract test validates workflow structure and failure behavior.

The AI workflow restores and verifies the plugin. The Python test checks workflow conditions, ordering, successful transfers, missing-artifact failures, and ProxySQL verification.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 1f77a

The workflows now hand off the GenAI plugin correctly, but the behavior test does not enforce that staging occurs before the handoff is packed, so a future reorder could silently produce an incomplete artifact. The PR is mergeable with explicit owner follow-up to add this ordering assertion.

Poem

A rabbit checks the plugin’s trail,
From build-cache paths to test detail.
It copies, restores, then verifies bright,
And flags a missing file outright.
CI hops cleanly through the night.

Learning: When using GitHub-flavored Markdown headings, be aware that an em-dash surrounded by spaces (written as ` — `) affects the generated anchor/slug: GitHub replaces spaces with hyphens and removes non-alphanumeric punctuation, which can produce double hyphens (e.g., `## Foo — bar` → anchor `#foo--bar`, not `#foo-bar`). If you reference these anchors (e.g., internal links), ensure the expected slug matches this behavior.

Learning: When reviewing GitHub-flavored Markdown links/anchors, remember that heading-to-anchor slug generation treats spaces as hyphens and removes punctuation. If a heading contains an em-dash surrounded by spaces (e.g. ` — `), the slugs can legitimately include a double hyphen where the two surrounding space-runs become `-` on either side of the removed em-dash (e.g. `...vocabulary--read...`). Do not flag double-hyphens in anchor links for em-dash-containing headings as errors; they reflect GitHub’s correct slug behavior.

Assert producer staging before test-cache packing.

If Stage GenAI plugin in test handoff moves below Pack test cache with zstd-15, this test still passes. The uploaded test handoff would then omit the plugin. Add an ordering assertion for the producer steps.

Proposed test update
+build_names = [step.get("name") for step in build_steps]
+assert build_names.index(stage["name"]) < build_names.index("Pack test cache with zstd-15")
+
 names = [step.get("name") for step in ai_steps]
