fix(ingest): a receiver typed with template arguments recorded no type, or the wrong class - #276
Conversation
…e, or the wrong class Rule 2 reads a receiver's type off its declaration, and ingest_binds.h writtenTypeOf recorded one only for a type_identifier or a qualified name. An unqualified template-id — `SmallVectorImpl<FunctionDecl *> &v`, `autovector<VersionEdit*> edits`, the way code inside its own namespace writes them — is a template_type node and recorded nothing, so `v.push_back( FD )` never reached Rule 2 or class identity while its qualified twin `llvm::SmallVectorImpl<…>&` did. The qualified path cut the spelling at its FIRST `<` (finalSegment), so `Outer<int>::Inner& in` recorded `Outer`: a precise edge to `Outer::size` wherever the outer class defines the method, and a fall to the name ladder where it does not (86 `X<…>::Y` receivers change target on the two corpora). The fix reads the last name through the grammar's own fields (lastNameNode: a qualified name's `name`, then a template-id's `name`) for written types and constructor names alike, and qualifiedNameText asks the same tree whether a scope was written, so a `::` inside a template ARGUMENT (`Vec<std::string>`) no longer marks the type qualified or stamps prov="final-segment" on its edge. scoped_type_identifier leaves the accepted kinds: no grammar that reaches this path (cpp, cuda, objc parser.c) has the symbol. Built and dropped: accepting an unqualified template_function constructor (`auto v = Vec<T>()`). It is every cast helper's spelling, recorded `dyn_cast` / `cast` as the type of `auto *CI = dyn_cast<CallInst>( I )` and `Spec = cast<FunctionDecl>( F )`, and tombstoned their written types: 994 more llvm-project sites retargeted, 779 of them edges lost (census diff of the build with and without it; of twelve sites read, ten show a cast-helper assignment or initialiser in the lines read, two were not traced). It is a stated floor, narrowcheck arm 39d. Measured, `--pin-census --no-cache`, C rows joined on (caller id, callee, line), main 13a1916 vs this change: rocksdb 0e2801ac3 640 target-changed sites, bound +347; llvm-project 4d5358b1d 5,231 sites, bound +3,589. Composed with #268 (scratch merge of e5ca33b + this commit, never pushed): 657 and 18,050 sites, bound +12,702 on llvm. Seeded sample of 100 (seed 20260917; 20 + 30 standalone, 12 + 38 composed), graded blind by independent readers with A/B order randomised per site: 99 better, 1 same, 0 worse — 62 NONE->RIGHT, 24 WRONG->RIGHT, 5 PARTIAL->RIGHT, 1 WRONG->PARTIAL, 7 NONE->PARTIAL (#268's template-family split), 1 PARTIAL->PARTIAL. Every lost edge was read: none on rocksdb; nine on llvm — seven a name declared twice in one function with different types (Rule 2's flat per-function table drops both, as for two plain types), two `auto T = EytzingerTable<…>::create( … )` that recorded `EytzingerTable` only through the cut and now read `create`, as `Foo::create()` always did. kParserVer 99 -> 103 with its quality.h mirror (100-102 are declared by the lanes queued ahead; the landing train assigns the number); test/qschemetrip.hash re-pinned with a RE-PIN LOG entry. Record layouts unchanged. Gate: test/narrowcheck.sh arms 39-43 (fixture generated in-gate). Red on main 13a1916: 39a-c, 40a-b, 41a-c, 43 (9 rows). Red on #268's head e5ca33b: those nine plus arm 42 x3 — the qualified twin splits to both TBase push_backs, the unqualified parameter, local and in-namespace twins decline. Red on a variant that reads qualification off the whole spelling: 40b alone (prov=[final-segment]).

Valid — fixed in 97b499f. The entry copied "stays 12" from the older RE-PIN LOG rows, which record the value current at the time; src/quality.h:2888 declares kQSnapCacheScheme = 14 on this tree (train 1: #253 → 13, #255 → 14). It is a comment only: the hashed manifest is quality.h / ingest_cache.h text, not this gate, so test/qschemetrip.hash does not move (qschemetripcheck, gateexitcheck, manifestcheck, qextractionkeycheck ALL PASS).

…lled that, onto train 3 Resolutions (TRAIN3_NOTES_278.md, plus the four the author's later scratch merge found): - src/ingest_binds.h: #276's ctorNameNode comment ("Last name") plus #278's assignment sentence. - src/resolve.h: #278's classNameSet and assignmentNamesNoClass above train 3's FlatRecvType comment, which also covers Rule 2b's Class#field table. - src/ingest_cache.h: train 1's readRef (u16Of32) with #278's writeBind/readBind byte; kCacheVersion 23 from #278 alone; kParserVer 105 after small-fixes' 104 (both sides said 104), #278's note renumbered above the 104..100 notes. - src/quality.h: train 1's static_assert note; kIngestCacheVersionMirror 23 and kIngestParserVerMirror 105 with #278's note. - test/narrowcheck.sh: header bullets 39-43 then 44-51; the arm bodies merged in order (dispatchfix 26-38, tmplfix 39-43, assignfix 44-51). - test/qschemetripcheck.sh: #278's RE-PIN LOG entry, renumbered, under train 3's; test/qschemetrip.hash keeps the train's pin until the final re-derive. - CHANGELOG.md: #278's entry after small-fixes' entries, its parser-version sentence renumbered.

…he composed tree #278 removes the ASSIGNMENT half of the floor's stated reason (`Spec = cast<FunctionDecl>( F )` no longer records `cast`), so the numbers were re-measured on this tree: a variant binary that reads an unqualified template-id callee in ctorNameNode, `--pin-census --no-cache` against the train binary, joined on (caller id, callee, line). llvm-project 4d5358b1d: 463 sites move, 324 edges lost, 137 retargeted, 2 gained; rocksdb 0e2801ac3: none. Sampled against source, every loss is a DECLARATION conflict — a cast helper's name beside the declaration's written type (`const ConstantInt *CI = dyn_cast<ConstantInt>( V )`, `StructType *STyL = cast<StructType>( TyL )`) or beside a second declaration (`CallInst *I = cast<…>` and `auto *I = dyn_cast<Instruction>( V )`), and the four retargets sampled were all worse. The floor stays and arm 39d still passes; its reason is rewritten in ingest_binds.h ctorNameNode, narrowcheck's arm 39 header and #276's CHANGELOG entry, and #278's entry names the base of its own 245/170 measurement.

…pe it was declared with Rule 2 records a C++ assignment from a call as the variable's type, so `x = Foo()` types `x`. A constructor call and a function call are one grammar node, so the record held the callee's last name whatever it was: `PHI = PHINode::Create( … )` recorded `Create`, `s = GetDBOptionsFromMap( … )` recorded `GetDBOptionsFromMap`, `t = llvm::cast<T>( y )` recorded `cast`. Rule 2's flat per-function table tombstones a variable whose records disagree, so the non-type erased the declared `PHINode *PHI` / `Status s`, and the call fell to the name ladder. The field use-site index (--uses=Owner.field) lost the same pin, and a MEMBER assigned from a call read as a local, so Rule 2b refused its declared type. graph.h's varType note said such a type "simply never produces a type::method hit"; that was true of the narrow and false of the tombstone. The fix: ingest marks an assignment's record (RawBind/Binding::isFromAssignment, ingest_binds.h assignedTypeOf), and buildGraph drops it unless a class of that name exists (resolve.h assignmentNamesNoClass, with the class-name set Rule 2c already built, now built first) — from Rule 2's varType table, from collectFieldUseSites' table and from the local-name set Rules 2b/2c and the external veto read. A declaration's callee-read type is kept: that declaration exists with an unrecorded type, and its conflict with a sibling declaration is what keeps one block's type off the other's calls. Measured, `--pin-census --no-cache`, C rows joined on (caller id, callee, line), main fe28fd4 vs this change: rocksdb 0e2801ac3 1,871 sites change target, bound +1,562 (1,544 newly bound, 327 retargeted, 0 lost; 1,494 are Status::ok); llvm-project 4d5358b1d 4,046 sites, bound +2,984 (2,859 newly bound, 1,187 retargeted, 0 lost). Seeded sample of 60 (seed 20260917; 25 rocksdb, 35 llvm), graded blind by independent readers with A/B randomised per site: 51 better, 6 same, 3 worse (39 NONE->RIGHT, 5 WRONG->RIGHT, 4 PARTIAL->RIGHT, 2 NONE->PARTIAL, 1 WRONG->PARTIAL; 4 WRONG->WRONG, 2 RIGHT->RIGHT). The three worse are resolver floors the tombstone had masked: rocksdb `Iterator*` narrowing onto memtable namesake `Iterator` classes, and two arity picks of the wrong overload of the right class. The local-name-set part alone moves 23 rocksdb and 132 llvm sites; 15 graded 10 better, 2 same, 3 worse — two of those expose Rule 2c reading a member named like a class (`std::unique_ptr<ToolOutputFile> OutputFile`) as that class, a floor this change unmasks and does not cause. Built and rejected: dropping a DECLARATION's callee-read type too. +89 llvm sites (0 rocksdb), 15 graded 11 better, 2 same, 2 worse, but it hands one block's written type to a sibling block's `auto t = ns::cast<Decoy>( y )` — arm 48. Considered for redhat-et#276's floor (narrowcheck arm 39d, unqualified `Vec<T>()` constructors): a scratch composition of redhat-et#276 50b97b7 + this change reading that spelling moves 245 llvm sites, 170 lost and 0 gained (779 lost before this change), all declaration conflicts like `auto *LI = cast<LoadInst>( … )` beside another `LI`. The floor stays. Format: the bind record gains one u8 (kCacheVersion 22 -> 23, kMinBindRecordBytes 26 -> 27, cachefuzzcheck's walker reads it); kParserVer 99 -> 104 with both quality.h mirrors (100-103 are declared by lanes queued ahead; the train assigns); test/qschemetrip.hash re-pinned with a RE-PIN LOG entry. graph.h stays line-neutral above rankGraphTeleport. Gate: test/narrowcheck.sh arms 44-51 (fixture generated in-gate). Red on main fe28fd4: 44, 45, 46, 49, 50 (no edge, owner_candidates="2", no census row). Red on variants built from this change: 48 when declarations are dropped too, 46 without the local-name-set filter, 51 when the new byte is not persisted. Green here, with arms 1-25.
