charset=UTF-8 Content-Transfer-Encoding: 8bit Collapse release-candidate.yml into publish.yml so there is exactly one workflow that publishes gitnexus to npm, creates GitHub Releases, and triggers Docker builds — for both release candidates and stable releases. Closes #1609 architecturally. A first-stage `route` job classifies push-to-main / push-tag / workflow_dispatch into `rc` / `stable` modes and fails closed on malformed shapes. RC path runs rc-guard → ci.yml → publish (mint GitHub App token → checkout with persist-credentials:false → resolve next rc version → atomic v-tag + rc/ marker push → vtag integrity gate → npm publish via OIDC → GitHub prerelease → if: failure() cleanup) → docker.yml. Stable path verifies package.json matches the tag and publishes to `latest` via OIDC (no docker). Hardening: • Self-trigger prevention via negative-glob `tags: ['v*', '!v*-rc.*']` — the bug class behind #1609 cannot recur. • Two distinct actions/checkout steps per mode (no conditional `token:` expression footgun). • Workflow-level `permissions: {}` deny-all + per-job grants; `id-token: write` only where OIDC is used. • npm Trusted Publishing replaces NPM_TOKEN (delete the secret after the first successful publish). • GitHub App installation token (actions/create-github-app-token@v3.2.0) replaces the long-lived RELEASE_PUSH_TOKEN PAT (delete after first successful RC). • vtag integrity gate fails closed on empty / mode-mismatched output (prevents Release named `main` from a github.ref fallback). • Annotation-injection sanitization on every logged ref. • Explicit `secrets:` passthrough on docker.yml (DOCKERHUB_USERNAME, DOCKERHUB_TOKEN); ci.yml no longer inherits anything. • `if: failure()` cleanup auto-deletes v-tag + rc-marker on partial failure (eliminates the external-consumer phantom-version ingestion window). • ACTIONS_STEP_DEBUG window closed via `set +x` wrap on the inline auth-header compute. • Curated retry-loud error handling on `gh api` bot-user-id lookup and `npx semver`. Pre-merge validation: • 10-reviewer multi-agent code-review pass; 14 findings fixed inline (commit 820cefae), 6 deferred to follow-ups. • End-to-end dry-run rehearsal via workflow_dispatch (run 25919563064) validated route classification, rc-guard, App token mint, RC checkout, version resolver, vtag synthetic-regex check, and faithful tarball pack at the bumped version. • All zizmor findings on the unification commits closed. • Branch-protection required checks all green. Post-merge actions: • After the first successful RC, delete the `NPM_TOKEN` and `RELEASE_PUSH_TOKEN` secrets — they are no longer used. • The first real RC after merge is the live-fire test for steps dry-run could not exercise (atomic tag push, real npm OIDC handshake, GitHub Release creation, docker.yml under explicit secrets passthrough). The if: failure() cleanup step handles the partial-failure recovery automatically; the Rollback Runbook in CONTRIBUTING.md covers the rare cases auto-cleanup can't reach. --- .github/workflows/ci.yml | 16 +- .github/workflows/docker.yml | 11 +- .github/workflows/publish.yml | 834 +++++++++++++++++++++++- .github/workflows/release-candidate.yml | 459 ------------- .github/zizmor.yml | 9 +- CONTRIBUTING.md | 84 ++- README.md | 4 +- 7 files changed, 884 insertions(+), 533 deletions(-) delete mode 100644 .github/workflows/release-candidate.yml diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index dd07337b7..c28e49be9 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -11,14 +11,14 @@ permissions: # Concurrency convention: see CONTRIBUTING.md → "GitHub Actions — Concurrency Convention". # Hardcoded `CI-` prefix (not `${{ github.workflow }}`) because this workflow is -# invoked as a reusable workflow from publish.yml and release-candidate.yml.

When exceeded, the phase gracefully stops and logs a warning. Users can override via GITNEXUS_CROSS_FILE_TIMEOUT_MS env var. This prevents the analyze command from stalling for hours on very large repositories where per-file re-resolution is expensive. Fixes the reported issue where gitnexus analyze stalls at "Cross-file type propagation" for several hours on repos with 15000+ files.

Additionally, progress was only reported once at the start, making the phase appear completely frozen. Fixes: - Add optional `compiledQueryCache` parameter to `processCalls` so callers that invoke it with single-file batches can share compiled query objects across calls. The cross-file phase now compiles each language's query string exactly once and reuses it for all files of that language (e.g. 1 TypeScript compile for 595+ files). - Pre-count candidate files and emit onProgress every 25 files showing "Cross-file type propagation (N/M files)..." so the UI shows real movement instead of a frozen bar. - Keep the wall-clock deadline (GITNEXUS_CROSS_FILE_TIMEOUT_MS) as a safety net for pathological inputs.

Fix: check isRegistryPrimary(lang) in both the totalCandidates pre-count loop and the levelCandidates builder, before any file I/O or map building. This eliminates 595+ no-op processCalls invocations on large TypeScript repos. Test: mocks isRegistryPrimary to always return true and verifies that processCalls is never invoked and result is 0. The mock also defaults to false in beforeEach so existing tests using .ts files are unaffected.

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(cpp): add standard-conversion-sequence ranking to overload resolution (#1578) Introduce `ConversionRankFn` abstraction and `cppConversionRank` implementation to disambiguate C++ overloaded calls by argument-to-parameter conversion cost. Exact type match (rank 0) beats standard arithmetic conversion (rank 2), which beats non-viable mismatch (Infinity). Thread the rank function through `narrowOverloadCandidates`, `pickImplicitThisOverload`, `pickOverload`, and `pickUniqueGlobalCallable` via the `ScopeResolver.conversionRankFn` contract. Add `findAllCallableBindingsInScope` scope walker for collecting all overloads at the first binding scope. Guard against false ambiguity suppression when candidates span different files (local-shadows-import preservation). * fix: address Claude review findings on conversion-rank PR Finding 1 (HIGH): add tests that exercise the conversion ranker. - p('a') with p(int)/p(double): char→int promotion (rank 1) beats char→double conversion (rank 2), forcing step 4b in narrowOverloadCandidates. Exact-type filter misses both overloads. - h(42, 2.5) with h(int,int)/h(double,double): multi-arg tied total score forces the ranker, both candidates score 2 → suppressed. Finding 2 (HIGH): unify multi-candidate suppression across all paths. - Non-ADL free-call: suppress when narrowed.length > 1 (same-file guard), mirroring ADL merged-candidate behavior. - ADL ordinary-only: same pattern. - pickOverload: return OVERLOAD_AMBIGUOUS when candidates.length > 1 after normalized-ambiguity check. - Case 0.5 (this receiver): set ambiguous=true when narrowed > 1. Finding 3+4 (MEDIUM): implement rank-1 integral promotions. - char→int and bool→int now return rank 1 (ISO C++ [conv.prom]). - Updated comment to remove misleading ISO table header; document only the post-normalization ranking that is actually implemented. - Updated ConversionRankFn JSDoc in overload-narrowing.ts. 218/218 C++ tests pass (registry-primary). Legacy: 186+32. * fix: implement pairwise dominance comparison for overload ranking Replace the summed per-slot conversion cost with ISO C++-aligned pairwise dominance comparison ([over.ics.rank]). F1 is better than F2 only when F1 is not worse for every argument and strictly better for at least one. Non-dominated candidates are returned; if multiple remain they are genuinely ambiguous. This fixes false CALLS edges for asymmetric multi-arg overloads: h('a', 2.5) against h(int,int) / h(double,double) — the old summed cost picked h(double,double) (cost 2 < 3), but ISO C++ considers the call ambiguous because h(int,int) is better at arg 0 via char promotion. The pairwise check correctly finds neither dominates. Add h('a', 2.5) test case asserting zero CALLS edges alongside the existing h(42, 2.5) symmetric-tie test. 218/218 C++ tests pass (registry-primary). Legacy: 186+32. * docs: update step 4b JSDoc to reflect pairwise dominance --------- Co-authored-by: Gergő Magyar --- .../languages/cpp/conversion-rank.ts | 47 ++++++ .../ingestion/languages/cpp/scope-resolver.ts | 5 + .../contract/scope-resolver.ts | 15 ++ .../passes/free-call-fallback.ts | 135 +++++++++++++++--- .../passes/overload-narrowing.ts | 107 ++++++++++++++ .../passes/receiver-bound-calls.ts | 29 +++- .../scope-resolution/pipeline/run.ts | 1 + .../cpp-overload-conversion-rank/lib.cpp | 10 ++ .../cpp-overload-conversion-rank/lib.h | 33 +++++ .../test/integration/resolvers/cpp.test.ts | 74 ++++++++++ .../test/integration/resolvers/helpers.ts | 13 ++ 11 files changed, 446 insertions(+), 23 deletions(-) create mode 100644 gitnexus/src/core/ingestion/languages/cpp/conversion-rank.ts create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-overload-conversion-rank/lib.cpp create mode 100644 gitnexus/test/fixtures/lang-resolution/cpp-overload-conversion-rank/lib.h diff --git a/gitnexus/src/core/ingestion/languages/cpp/conversion-rank.ts b/gitnexus/src/core/ingestion/languages/cpp/conversion-rank.ts new file mode 100644 index 000000000..2a9e3bc01 --- /dev/null +++ b/gitnexus/src/core/ingestion/languages/cpp/conversion-rank.ts @@ -0,0 +1,47 @@ +/** + * C++ conversion-rank scoring for overload resolution (#1578). + * + * Operates on **normalized** type strings (output of + * `normalizeCppParamType` in `arity-metadata.ts`).
