Audit all GitHub Actions workflow timeouts against actual run durations and consolidate to 4 consistent tiers:

  • 10 min: quick utility jobs (labels, lints, deploys, reports)
  • 30 min: standard CI build/test/lint, docs build
  • 120 min: heavy compute (benchmarks, packaging, publishing, fuzz-coverage)
  • 240 min: marathon fuzz runs and corpus minimization

Notably, fuzz-coverage was hitting its old 60-min timeout and getting cancelled on most runs — bumping to 120 fixes that.

Timeout tiers

Tier Timeout Purpose Safety margin
⚡ 10 min Quick utility jobs (labels, lints, deploys, reports) ~100×+ over typical
🔨 30 min Standard CI build/test/lint, docs, packaging, publishing ~5× over slowest job in tier
🏋️ 120 min Heavy compute (benchmarks, python packaging, fuzz-coverage) ~2× over slowest job in tier
🔬 240 min Marathon fuzz runs and corpus minimization Matches libfuzzer/wasmfuzz time configs

🏋️ Tier 3 — 120 min

Workflow Job Previous timeout Max observed duration
bench-pr.yml bench 120 min ~42 min
bench.yml bench 120 min ~42 min
claude.yml claude ❌ none variable (AI agent)
fuzz-coverage.yml coverage 60 min ⚠️ ~60 min (was hitting timeout!)

package.yml prepare-python 120 min ~40 min
release-binaries.yml build 120 min ~40 min
sql-benchmarks.yml bench 120 min ~60 min (nightly SF=100)

🔬 Tier 4 — 240 min

Workflow Job Previous timeout Max observed duration
run-fuzzer.yml fuzz 230 min ~50 min (libfuzzer max_total_time=2700s)
wasm-fuzz.yml wasm-fuzz 270 min up to 3h30m (wasmfuzz --timeout=3h30m)
minimize_fuzz_corpus_workflow.yml minimize ❌ none (6h default) variable

Also lowered wasmfuzz --timeout from 4h to 3h30m so the fuzz step itself fits within 240 min with ~30 min headroom for build/setup/teardown.

Notable fixes

  • fuzz-coverage was silently broken: the old 60-min timeout was being hit on 4 out of 5 recent runs (all cancelled at ~61 min). Bumping to 120 min fixes this.
  • 14 jobs had no timeout at all, defaulting to the GitHub Actions 6-hour maximum. All now have explicit timeouts.
  • sqllogic-test in CI had no timeout — now set to 30 min.

chore: standardize workflow timeouts to 4 tiers (10/30/120/240)
6199963 
Audit all GitHub Actions workflow timeouts against actual run durations and
consolidate from 9 different values (2, 10, 30, 40, 60, 90, 120, 230, 270)
down to 4 consistent tiers:

- 10 min: quick utility jobs (labels, lints, deploys, reports)
- 30 min: standard CI build/test/lint, docs build
- 120 min: heavy compute (benchmarks, packaging, publishing, fuzz-coverage)
- 240 min: marathon fuzz runs and corpus minimization

Also adds timeout-minutes to 14 jobs that previously had none (defaulting
to the GitHub Actions 6-hour maximum), including sqllogic-test in CI and
the fuzz corpus minimization job.

Notably, fuzz-coverage was hitting its old 60-min timeout and getting
cancelled on most runs — bumping to 120 fixes that.
