merge: reconcile upstream through e8ec7fd8 (C++ member-chain calls, test temp-dir cleanup) by bompus · Pull Request #513 · bompus/codegraph

bompus · 2026-10-17T00:06:36Z

Brings fork/consolidated up to upstream main e8ec7fd8. Upstream's two C++ member-chain fixes need no resolver change here: the Rust resolver already links thread->rand.Next() to the member's class and gives no edge for options.cf_paths.emplace_back(…) on a std::vector. This PR adds upstream's tests for that behavior and its test temp-dir cleanup.

The merge commit keeps upstream's parent, so land it as a merge commit.

What was ported

test: stop test runs leaving temp dirs behind colbymchenry/codegraph#2622 test: stop test runs leaving temp dirs behind: merged as written. vitest runs upstream's home-sandbox teardown after the fork's per-run temp directory setup.
test: wait for what holds an MCP test's dir before removing it colbymchenry/codegraph#2624 test: wait for what holds an MCP test's dir before removing it: merged as written. mcp-initialize's teardown uses upstream's removeWhenReleased in place of the fork's rmTempDir.
fix(cpp): a call on a member reached through other members, like options.cf_paths.emplace_back(…) on a std::vector, no longer links to a project method of that name colbymchenry/codegraph#2626 fix(cpp): library-type member chains: the behavior was already native. __tests__/cpp-member-chain-outside-calls.test.ts (6 tests) passes with no kernel change.
fix(cpp): a call on a member reached through other members, like thread->rand.Next() on a Random64, links to the method of the member's class colbymchenry/codegraph#2627 fix(cpp): project-class member chains: the behavior was already native (cpp_complex_call → cpp_expression_owner / cpp_field_types in cpp_receivers.rs, which read the member from the class node C++ lookup found). __tests__/cpp-member-chain-project-calls.test.ts (6 tests) passes with no kernel change.

src/resolution/name-matcher.ts stays deleted. The CHANGELOG keeps the fork's entries and takes upstream's new wording of its two C++ member-call entries. The rebuild script would have restored four entries earlier reconciles removed on purpose.

Verification

Kernel rebuilt from the merged tree before testing. All 12 new tests pass on it, and also on an older fork kernel from before fix(kernel): C and C++ resolver defects reproduced in the #510 review #511. A sample of fix(kernel): C and C++ resolver defects reproduced in the #510 review #511's own tests fails on that older kernel (4 failures), which confirms the override reached the tests.
Golden dumps re-run with UPDATE_GOLDEN=1: 8/8, no .dump changes.
eval:precision: jq has 7,784 edges and no cases. json has 28,803 edges, 11/11 absent and 7/7 present cases held. The kernel sources are identical to the base commit, so these are the before and after figures.
leveldb (bb74ef7), indexed with this build. 15 sampled linked member-chain calls were read by hand and all are correct, e.g. thread->rand.Uniform → Random::Uniform and t.meta.smallest.DecodeFrom → InternalKey::DecodeFrom. The kernel is unchanged, so the before and after graphs are the same build: 0 edges added, retargeted or removed.
Full suite: 744 files, 9,256 passed, 40 skipped; no Native stack trace or Worker exited unexpectedly in stderr.
npx tsc, npm run check:agent-docs and cargo clippy --release --lib -- -D warnings pass.

README rows checked: the upstream merge point (updated to e8ec7fd8) and the C++ rows under the fork's differences (the data-member line still holds: member chains take the declared type, as upstream's now do). No numbers moved.

Not covered

On leveldb, member-chain calls of these shapes stay unlinked in the fork. Upstream's kit A/B reports 42 added and 30 retargeted calls in leveldb, so upstream likely links some of them. I have not run upstream's build to confirm which.

A member of a struct defined out of line as a nested class, like struct DBImpl::CompactionState { Compaction* const compaction; } with compact->compaction->level(): about 60 candidate sites (a few are correctly unlinked standard-library calls) in db_impl.cc, table_builder.cc and table.cc.
A member of a global-namespace struct whose type comes in through using ns::WriteBatch;, like b->rep.Clear(): about 25 sites in db/c.cc.
A local built with constructor-call syntax, like SharedState shared(n); shared.mu.Lock(). Tree-sitter reads this as a function declaration. A one-hop shared.Go() and the brace form both link.
this->mu_->Lock() inside a class written with an attribute macro (class SCOPED_LOCKABLE MutexLock).

These are left for a follow-up fix.

Summary by cubic

Reconciles fork/consolidated with upstream main through e8ec7fd8. The two C++ member-chain fixes need no resolver change — the Rust kernel already resolves thread->rand.Next() to the member's class and gives no edge for options.cf_paths.emplace_back(…) on a std::vector — so this brings in upstream's tests for that behavior and ports its test temp-dir cleanup. Land as a merge commit.

Ported from upstream

Home sandboxes are removed at the end of a run even when a suite skips every test, and mcp-initialize's teardown waits for a held dir before removing it.
The 12 new C++ member-chain tests pass unchanged on the rebuilt kernel; full suite passes (9,256 tests) with no kernel changes.

Not covered

Four leveldb member-chain shapes stay unlinked in the fork: members of out-of-line nested structs, types reached through using ns::WriteBatch;, locals built with constructor-call syntax, and a this-> member inside an attribute-macro class. Upstream's kit A/B reports 42 added and 30 retargeted calls in leveldb, so upstream likely links some of them; left for a follow-up.

Summary by CodeRabbit

Bug Fixes
- C++ calls through members and chained member access now resolve to methods declared on the member’s type, using declarations visible to the calling file. Unrelated same-named project methods are no longer linked, including for calls through external types and raw pointers. Supported smart-pointer, iterator, and optional dereferencing remains intact.
Chores
- Improved cleanup of temporary test directories and home sandboxes.
Documentation
- Updated the documented upstream baseline.

Every full test run left about 40 directories in the temp dir, even when it passed. On the Windows dev machine about 16,000 had piled up by mid-October. A full run with TEMP pointed at an empty folder showed where each one came from: - function-ref (20) and ts-field-classification (3): each case's `finally` cleared `tmpDir` right after `cg.destroy()`, so the `afterEach` that removes the dir found nothing to remove. - npm-sdk (3) and liveness-watchdog (3) never removed the dirs they made. - extraction's colbymchenry#1502 suite (3) made a dir in `beforeEach` and had no `afterEach`; pr19-improvements' schema-version case (1) made one inline. - setup-home-sandbox (6 on Windows): Vitest runs no hooks for a file whose every test is skipped, so each platform-gated file left its home sandbox. Each sandbox now records itself in a per-run registry, and a global teardown removes whatever is still listed and names any dir still in use. With the fix, the same full run leaves nothing behind but Node's own reused compile cache. test-home-sandbox gains two tests: a file's home is listed in the run's registry, and the teardown removes every listed home, then the registry.

…mchenry#2624) Two MCP test files sometimes failed under full-suite load on Windows with EBUSY in their afterEach, and then left their temp dir behind: - mcp-status-freshness: every case leaves an index-freshness measurement worker still ending, and the deadline case's worker is terminated in the middle of its measurement. Until it exits, the worker can hold the index or the project dir, and the removal raced that exit (EBUSY on codegraph.db or on the dir, ENOTEMPTY on .codegraph). The afterEach now awaits endFreshnessMeasurements(), the server's own shutdown wait, before it closes the index and removes the dir. - mcp-initialize: after the killed server's 'close', the dir itself can stay busy a moment longer (EBUSY rmdir). It freed within about 80 ms, with no process left under the server. A bounded `maxRetries` doesn't help: on Node 22, fs.rmSync never retries EBUSY on a directory and throws at once. So removeWhenReleased() retries the removal itself, for up to 5 s, and a Windows-only test holds a dir as a child's cwd to prove the helper waits. Under CPU load (14 of 16 cores busy, two runs at once), the status teardown failed 20 times in 240 without the wait and 0 times in 240 with it. Alternating real runs of both files failed in 5 of 18 on main and 0 of 10 with the fix. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…ions.cf_paths.emplace_back(…)` on a `std::vector`, no longer links to a project method of that name (colbymchenry#2626) The extractor records a call on a member chain (`a.b.m()`, `a->b->m()`, `this->p_.m()`) by its bare method name, so it went to whichever project method shared the name. A census of the cgstd kit found most such calls linked by name alone, and most of those links wrong. Above all, they were on members of standard-library types, whose methods (`size`, `reset`, `push_back`, `get`, `empty`) a large codebase has namesakes of. matchCppOutsideMemberChainCall reads the chain where the call is written (cppMemberChainReceiver) and types it with the existing cppMemberObject: - a data member is typed by its declared type in its class (cppDataMemberType); - `->` goes through a pointer, smart pointer, optional or iterator. It gives no edge when the object the method is called on is a library type (isCppLibraryType) or a type under a namespace the project declares nothing in (isCppOutsideQualifiedType). These are the call-chain resolver's rules. Unlike a call chain, the operator is read as written, so `.` on a `std::vector<T>` or a `std::unique_ptr<T>` is that type's own member, whatever `T` is. Anything else, a member of a project class included, goes to the name strategies as before. Kit A/B against main a257069 (only removals; nothing added or retargeted): | repo | calls removed | |---|---| | rocksdb | 2,001 | | protobuf | 234 | | leveldb | 15 | | fmt | 12 | | redis | 0 (identical) | Every removed link was a bare-name guess. Of the 2,235 removed sites in rocksdb and protobuf, a judge reading the members' declarations across each repo rated: - 2,044 as wrong links (a library type's namesake, or an unrelated class); - 165 unknown; - 10 not counted as chains by its pattern (after a cast, like `(int)data->entries.size()`); - 16 right. These turned out to be name collisions on the judge's side, checked in the source (`std::deque logs_`, `std::shared_ptr decompressor`, `std::vector ids`). 24 random removals were also read by hand, and all were correct.

…ead->rand.Next()` on a `Random64`, links to the method of the member's class (colbymchenry#2627) Step 2 of member chains; colbymchenry#2626 was step 1. matchCppMemberChainCall (formerly matchCppOutsideMemberChainCall) now also resolves a chain whose member is of a project class, in the same steps matchCppUnspelledReceiverCall takes for `it->second.Flush()`: - the class C++ lookup finds for the member's type, where that type is written; - then its method, or one it inherits (cppMethodOf, with overloads picked by argument types); - or no edge when the class surely lacks it (cppLacksMethod). Before, such a call went by its bare name to whichever class had a method of that name. Inside a method it could also be taken for an implicit `this` call on the method's own class. A member is now read from the class node C++ lookup found (cppDataMemberIn), not from the first class of that qualified name that declares it (cppDataMemberType, removed). rocksdb's db_bench_tool.cc and db_stress_shared_state.h each declare a ROCKSDB_NAMESPACE::ThreadState, whose `rand` is a Random64 in one and a Random in the other. Kit A/B against main 6e884d7: | repo | added | retargeted | same target, now typed | removed | |---|---|---|---|---| | rocksdb | 571 | 2,008 | 1,738 | 2 | | protobuf | 42 | 95 | 142 | 0 | | leveldb | 42 | 30 | 141 | 0 | | fmt | 0 | 56 | 20 | 0 | | redis | 0 | 0 | 0 | 0 (identical) | The most common rocksdb retargets are DBImpl -> DB (calls on a `DB*`), BlobContents -> Slice, BlobFileReader -> FileDescriptor and EnvWrapper -> Env. Hand-reading random samples found one wrong retarget (db_bench's `thread->rand.Next()`, the ThreadState namesake), which led to the member-lookup fix above. After that fix, all 76 sites sampled across the four repos were correct: - 30 retargets and additions, plus both removals, in rocksdb; - 20 in protobuf, 14 in leveldb and 10 in fmt. The two removed calls are `task_reader->rep_->GetCoroutine(…)` on a `SstFileReader::Rep`, which has no such method. They had linked to `CoroDB`'s.

…st temp-dir cleanup) Merge colbymchenry/codegraph main e8ec7fd into fork/consolidated. The fork resolves references in the Rust kernel, so name-matcher.ts stays deleted. Its upstream version (matchCppMemberChainCall, cppDataMemberIn) is the specification for the native port that follows this commit. The test changes merge as written, alongside the fork's per-run and per-file temp directories: vitest runs upstream's home-sandbox teardown after the fork's run-directory setup, liveness-watchdog keeps the fork's fake-timer import, and mcp-initialize's teardown uses upstream's removeWhenReleased. CHANGELOG.md keeps the fork's entries and takes upstream's new wording of its two C++ member-call entries. The rebuild script would have re-added the VB.NET, CRLF store, string-literal and duplicate std::unique_ptr entries the fork removed in earlier reconciles.

📝 Walkthrough

The pull request adds C++ member-chain call-resolution tests and changelog entries. It updates temporary-directory cleanup across test suites, adds run-level home-sandbox cleanup, and changes the upstream baseline commit listed in the README.

Changes: C++ Member-Chain Resolution

Layer / File(s)	Summary
Project member-chain calls `__tests__/cpp-member-chain-project-calls.test.ts`, `CHANGELOG.md`	Tests cover method selection through member chains, including inheritance, overloads, and classes with the same name in different files. The changelog describes these resolution cases.
External-type member calls `__tests__/cpp-member-chain-outside-calls.test.ts`, `CHANGELOG.md`	Tests cover library and external-type calls that should not match unrelated project methods, while retaining expected project calls through pointees and project members. The changelog records these cases.

Test Temporary-Resource Cleanup

Layer / File(s)	Summary
Home-sandbox registry `__tests__/global-setup-home-sandbox.ts`, `__tests__/setup-home-sandbox.ts`, `__tests__/test-home-sandbox.test.ts`, `vitest.config.mts`	Global setup creates a registry for sandbox paths. Test setup records paths, cleanup removes registry entries, and tests cover registry cleanup.
Per-test directory cleanup `__tests__/extraction.test.ts`, `__tests__/function-ref.test.ts`, `__tests__/liveness-watchdog.test.ts`, `__tests__/npm-sdk.test.ts`, `__tests__/pr19-improvements.test.ts`, `__tests__/ts-field-classification.test.ts`	Tests add cleanup for temporary directories. Some tests now rely on shared cleanup hooks instead of resetting directory state in individual `finally` blocks.
Coordinated resource removal `__tests__/mcp-initialize.test.ts`, `__tests__/mcp-status-freshness.test.ts`	MCP initialization cleanup retries removal for selected filesystem errors and adds a Windows test for a directory held by another process. Freshness-test cleanup waits for measurements before closing the graph and removing the project directory.

Documented Upstream Baseline

Layer / File(s)	Summary
Upstream commit reference `README.md`	The fork description changes the included upstream baseline from `19813544` to `e8ec7fd8`.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to ad3a5

The change is mergeable with a targeted follow-up test for external raw-pointer calls; no current resolution failure is established.

Security architecture risk: ⚪ Minimal · up to ad3a5

The changes remain within test infrastructure and regression coverage. Cleanup gains a run-wide fallback without changing application access, credentials, public APIs, or deployment behavior. No material security risk was identified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The new cleanup authority operates within the test-runner account's existing filesystem privileges. Its intended targets are temporary homes recorded by test setup, not tenant resources or production stores.

Trust Boundaries and Controls

inferred — Teardown trusts registry contents as deletion targets without containment validation. The inspected writer records a freshly created, resolved temporary home; exploiting altered records would require registry-write access. No new lower-trust input path into that registry was established.

Full details: Suppressions Explained

Explanation

No changed line adds or broadens a lint, type-check, or compiler-diagnostic suppression. The only changed configuration is vitest.config.mts, which adds a global setup file. The stdio: ['ignore', 'pipe', 'ignore'] value configures child-process streams and is not a diagnostic suppression.

Full details: User-Visible Changes Documented

Explanation

PASS. The diff does not add, remove, or rename a CLI command or flag, MCP tool argument, supported language/framework, agent target, or configuration key. It adds test fixtures and cleanup setup; globalSetup already existed in vitest.config.mts and only receives an additional test setup file. The README change only updates the fork's upstream commit reference.

Add direct raw-pointer coverage for external strings.

TwoHops tests a project raw pointer that reaches a std::string member. It does not test a raw pointer whose own type is external. Add std::string* out with out->clear(). The fixture already defines rocksdb::autovector::clear(), so the assertion detects a regression that incorrectly resolves the bare method name to a project method.

Review: #513 (review)
Head: ad3a552
Reason: Declined (nitpick on __tests__/cpp-member-chain-outside-calls.test.ts, the std::string* out; out->clear() case). The file is upstream's colbymchenry#2626 test, taken as written; reconcile PRs here keep upstream's tests unchanged so later upstream merges stay conflict-free. A raw-pointer-to-external-type case is a fair fork-side addition and I will fold it into the next C++ member-chain test change rather than edit an upstream file in a merge.
