…hares its last name, and rocksdb::DB is RocksDB's own (colbymchenry#2567) A C++ receiver declared with a namespace-qualified type is from outside the project only when no class of the project can be what that name names. Three cases read that wrong on main: - A namespace a macro stands for. RocksDB declares its classes in `namespace ROCKSDB_NAMESPACE` under `#define ROCKSDB_NAMESPACE rocksdb`, so the index names them `ROCKSDB_NAMESPACE::DB`, and colbymchenry#2532's outside rule (cppProjectScopeNames) never saw `rocksdb`: `rocksdb::DB* db; db->Put(…)` got no edge. cppProjectScopeNames now adds the name a single-name macro stands for, in both directions (cppNameMacros, the map cppNamespaceMacros already builds). - A lowercase outside type beside a project namesake. isCppLibraryType (colbymchenry#2413) took a non-std lowercase type as the library's only when no project type had its name at all, so `absl::flat_hash_set<int> seen; seen.insert(…)` reached a project's own `util::flat_hash_set::insert`. It is now also the library's when every project type of that name is a namesake (cppFindsOnlyNamesakes). - A capitalized type whose last name finds only namesakes, on the paths colbymchenry#2493's call-site rules leave to the last-name match: a declaration read outside the calling function (protobuf's `absl::Status _status` in its RETURN_IF_ERROR macro body reached `upb::Status::ok`; `auto bytes = ::hpb::Serialize(…); bytes.value()` reached `hpb::StatusOr::value`), and a namespace the project uses (its generated `DescriptorProto::ExtensionRange`, which the index doesn't hold, reached `Descriptor::ExtensionRange::options`). That call now gets no edge, as isUndeclaredTypeName rules where no class shares the name; `->` on a value still goes to the name strategies, and a template parameter's member is left alone. cppFindsOnlyNamesakes: every type of the last name, and every owner of a method of the called name (the index can hold a class's methods without the class), has a qualified name that ends unlike the written one, neither the other's tail; namespace aliases are expanded and macro-named namespaces read both ways. A name a project type qualifies, an unqualified name and an unbalanced `<>` are never judged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
… global type (colbymchenry#2568) protobuf's hpb declares `class Arena { … backend::Arena arena_; }`, where `namespace backend = hpb::internal::backend::upb;` and that namespace says `using Arena = ::upb::Arena;`. cppTypeName dropped the leading `::`, so the alias's target was looked up as `upb::Arena` from the alias's own scope, whose nearest `upb` is that very namespace: the alias named itself, the lookup ended on no class, and `arena_.Fuse(other.arena_)` fell back to the type's last name, linking `hpb::Arena::Fuse` (and `IsFused`, `RefArena`) to itself instead of `upb::Arena::Fuse`. TypeName now records a leading `::` (`global`), and a global name is looked up from the global scope alone: when an alias's target is followed (follow, and the scope expand looks the target up from and hands on), in a class's base clause (baseClassesOf), and in cppAliasedTypeWritten, which colbymchenry#2532's `auto` locals and chains walk alias by alias.

…there, and a far lowercase outside type reaches no namesake (colbymchenry#2569) The two follow-ups colbymchenry#2567 and colbymchenry#2568 left open. A receiver declared with a leading `::` lost it: the declarator regex started a type at a letter, so `::upb::Arena& a` inside `namespace hpb` was looked up from `hpb` and found a namespace-local `hpb::upb::Arena`. The declared type now keeps a leading `::` where one can stand (not after a name, a template's arguments or a `)`, so `SkipList<Key, Comparator>::Iterator iter` is not read as `::Iterator`), and resolveCppAliasedType no longer takes a function-local `using Foo = Bar;` for `::Foo`. A lowercase outside type declared outside the calling function still used the last-name typed match: colbymchenry#2413's library rule skips such declarations, and colbymchenry#2567's namesake gate took capitalized types only. So a far `absl::flat_hash_set<int> seen` linked `seen.insert(v)` to the project's `util::flat_hash_set::insert`, and a far `std::string text` linked `text.clear()` to a global project `string` class. The gate now covers lowercase types, which are decided as when no class shares their name, and cppFindsOnlyNamesakes reads a `std::` name exactly.

… SkipList<Key, Comparator>::Iterator, is that template's member (colbymchenry#2573) The declarator regex read a type as a name plus one template argument list, so `SkipList<Key, Comparator>::Iterator iter(&list);` was read from its last name alone and looked up from the calling function: leveldb's skip-list tests linked `iter.Valid()` to `leveldb::Iterator::Valid`, rocksdb's to `IteratorBase::Valid`, and rocksdb's SkipListRep iterators linked their `iter_` member's calls (`InlineSkipList<…>::Iterator iter_;`) to their own methods. The type is now read whole, `Outer<Args>::Member`, and C++ lookup finds the member in the class template. A library template's member read this way is a library type only as an iterator (`std::vector<int>::iterator`, never a project class named `iterator`). Others name another type that may be the project's (`std::vector<Slice>::value_type`, gmock's `typename std::tuple_element<N - 1, MatcherTuple>::type matcher`), so their calls go on as before.

…ent's method (colbymchenry#2576) `std::deque<Slice>::const_iterator it; it->data()` was matched by the method's name alone, so it could reach any class with a `data`, and `itr->c_str()` on a `std::vector<std::string>::const_iterator` reached gtest's `FilePath::c_str`. A `->` on a value of an iterator type now reaches the container's element, as `->` on a smart pointer reaches what it holds: the element is read from the container's template arguments (cppRangeElementOf), before the container's own `iterator` alias would lose them (protobuf's `RepeatedPtrField<T>::iterator`), and looked up as C++ does. A library element (`std::string`) or the caller's template parameter calls no project method. An element only a class template's own `begin()`/`operator*` writes with its parameter (googletest's `ParamGenerator<T>::iterator`) goes on as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…s the element's method through `->` (colbymchenry#2579) `auto it = logs_.begin(); it->IsSyncing()` had no type for `it`: a call on a library container (`std::deque<LogWriterNumber>`) returned nothing the auto-local reader could use, so `->` calls on it were matched by the method's name. A standard or abseil container's `begin`/`end`/`find`/ `lower_bound`/`rbegin`/… now types as `<container>::iterator`, and a standard search (`std::lower_bound`, `std::find_if`, `std::next`, …) as the iterator it is given first; colbymchenry#2576's cppArrowTarget then reaches the container's element. The element is looked up where the container's type is written (the `auto` local's declared site, a data member's class), not where the call is: an element nested in another class (`vs->obsolete_files_.begin()`) finds that class's type, not a namesake visible at the call. A holder's type stays looked up at the call: from a pimpl member's header the lookup finds a namesake (protobuf's other `DescriptorIndex`) or nothing.

…()`, calls the method of what it points at (colbymchenry#2598) The extractor records `(*it)->Visit()` and `(*node).Weight()` by their bare names, which the name strategies then gave to whichever class had a method of that name (0.4-0.7 guesses), and a local a dereference sets, `auto first = *nodes.begin()`, had no type. `*x` and `x->` in C++ expression typing now dereference a container's iterator to its element as well as pointers and holders (cppDereferenced, used by cppExpressionType, cppMemberObject and cppChainInnerType), and a bare-name call written on `(*name)` (read at the call's column, where the receiver starts) is resolved on the dereferenced value's class by C++ lookup before the name strategies run: the method, or no project method for a library type, a template parameter's, or a class that lacks it.

…, `it->second.Flush()`, calls the value's method (colbymchenry#2601) The extractor records `it->second.Flush()`, `kv.second.Flush()` and `(*it).first.Print()` by their bare names, which the name strategies gave to whichever class had a method of that name — 45 `std::string::c_str()` calls went to googletest's `FilePath::c_str` — and a local such a member initializes (`auto& v = it->second`) had no type. `x.first` / `x.second` (and `->`) on a `std::pair` now type as the pair's elements in C++ expression typing (cppPairMember), so a map's iterator, range-for element or declared pair reaches its key and value, and colbymchenry#2598's bare-name receiver reader also takes `name->second`, `name.first` and `(*name).second`. A member typed by another class template's parameter (`CoreLocalArray<T>::AccessElementAndIndex()`'s `std::pair<T*, size_t>`) goes on as before: only the calling function's own template parameter names no particular class. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ound()`, calls the element's method (colbymchenry#2602) The extractor records a call on a subscripted receiver, like `statuses[i].IsNotFound()`, `buffers[key].Flush()` or `iters[i]->Valid()`, by its bare name, which went to whichever class had a method of that name, and a local an element initializes (`auto& s = statuses[i]`) had no type. - C++ expression typing reads a subscript: an array's element, what a pointer points at, a library map's mapped value, a sequence's element, or what a class's `operator[]` returns. - Declarations record their array dimensions (locals, parameters and data members, also through an alias), so a subscript, `*arr`, `arr->` and a range-for over an array read the type the array is declared with. - The bare-name receiver reader takes subscripts after a name or `(*name)`, reading the line with its literals blanked. - Overload arguments use the same subscript typing: a map's `values[key]` is its value type, no longer a `std::pair`. A/B vs main, every changed site triaged: leveldb 12 removed, 14 added, 1 retargeted, 11 metadata-only; fmt 6/4/10/2; redis identical; rocksdb 513/292/843/807; protobuf 58/5/34/66. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…OBUF_DEFINE_ACCESSOR(FieldDescriptor, number, int)`, is indexed where the macro is invoked (colbymchenry#2605) protobuf declares its descriptor accessors in their classes and defines them below with macros, like `PROTOBUF_DEFINE_ACCESSOR(FieldDescriptor, number, int)`; its reflection pastes `Reflection::Get##TYPENAME` in another. The parser never sees those definitions (the preParse blanks the invocations) and a declaration mints no node, so the methods had none and every call to them linked to nothing. - After either extractor (the kernel or the wasm walker), a step over the original source expands the file's own function-like macros whose body defines `Class::method(...) ... {`, at each invocation at namespace scope, and mints a method node per definition: named and qualified like an out-of-line definition, contained by the file and the same-file class, with the expanded head as its signature. Constructors, destructors and variadic macros are left out. - The parse worker leaves the raw kernel fast path only for a file that may define one (a cheap text test), so the step sees it. - The C++ resolver reads such a method's return type and parameters from its signature, and never takes it for a deleted overload. A/B vs main on the kernel path, every changed site triaged: leveldb and redis identical; fmt +13 nodes and rocksdb +11 (gtest's TestEventRepeater overrides); protobuf +257 nodes, 6,203 calls and 2 references added, 252 calls retargeted, 11 metadata-only, none removed. Kernel and wasm dumps are byte-identical, protobuf's one pre-existing Swift line aside. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…::ReadPrimitive<int32_t, WireFormatLite::TYPE_INT32>`, is named after its template (colbymchenry#2609) An explicit specialization of a function or member function template kept its template arguments in its name: protobuf's `template <> bool WireFormatLite::ReadPrimitive<int32_t, WireFormatLite::TYPE_INT32>(…)` was named `TYPE_INT32>` and qualified `…::ReadPrimitive::TYPE_INT32>`, the qualified id split at the `::` inside its arguments; rocksdb's `template <> int64_t Deserialize<int64_t>(…)` was `Deserialize<int64_t>`. A call writes the bare name, so nothing linked to them. Both extractors (wasm and the native kernel) now name a specialization after its template, from the template-id's own name, and take its receiver from the text before the declarator's name. That text must end in a real `::`: tree-sitter recovers Metal's `vertex VertexOut vertexShader(…)` with a missing, zero-width one. A specialization now meets its template among a name's candidates, so the resolver chooses between them wherever it picks among C++ candidates (a class's methods, the implicit-this walk and its bases, exact, qualified, global, fuzzy and macro-namespace matching): - a call that writes template arguments reaches the specialization written with the same ones (spacing aside, or qualified further on one side), else the template itself or an ordinary overload, else nothing: fmt's `num_bits<unsigned short>()` stays on `num_bits<T>()` instead of the nearer `num_bits<uint128>()`; protobuf's `Arena::Create<T>` keeps calling `DefaultConstruct<T>`, not the tests' `DefaultConstruct< DispatcherTestProto>` hook; a dependent `ReadPrimitive<CType, DeclaredType>(…)` links nowhere rather than to the first specialization. - a call that writes none, or `<>`, reaches a specialization only when nothing else has the name. - a class's own member template, specialized but none for these arguments, ends the lookup there instead of falling to a base's namesake. The `cpp-override` pass leaves specializations out on both sides: a member template is never virtual. Validated on the cgstd kit against main (f7951a1): leveldb and redis byte-identical; fmt: 8 specializations renamed, every call target as on main; rocksdb: the cassandra `Serialize<T>`/`Deserialize<T>` calls (25 in format.cc, 75 in its tests, which main sent to `ColumnBase` methods) each reach the specialization their argument names (100 of 100 agree); protobuf: `MergeFrom<MessageLite>` (3 calls), `ReadPrimitive<int, TYPE_ENUM>` (2) and a test's `ReadPackedPrimitive<uint32_t, TYPE_FIXED32>` reach their specializations; 5 dependent calls like `GetRepeatedFieldInternal<T>`, and one `MutableRepeatedFieldInternal<int>` (the macro writes `<int32_t>`), no longer link to the first specialization a macro defines. Kernel and wasm dumps identical (but for protobuf's known Swift line). Full suite: 7179 passed, 0 failed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…seWithLimit(limit, data, result)`, reaches the overload its arguments fit (colbymchenry#2612) A C++ call to a function outside a class took whichever same-named function the name strategies ranked first, by file and line proximity, never by its arguments. Methods already picked their overload by argument count, string literals and written argument types (cppOverloadFor); functions never did. protobuf's `ParseWithLimit(limit, data, result)` on an `int32_t result` reached the `int64_t&` overload beside the call, and rocksdb's `NewLRUCache(cache_opts)` the overload taking a `size_t capacity`. Exact, qualified (global, exact, partial) and macro-namespace matching now keep their choice of function, then let the call's arguments pick among its overloads, the functions of its qualified name the call's file can see (cppFunctionOverload, with cppOverloadFor's count-then-type fit; the macro-namespace scorer breaks its ties by type). The choice stays on a tie. - An overload only another source file sees (another `.cc` file's `static`, an unnamed namespace's) never competes. When the name strategy had picked such a function, which was then rejected, the call now links to the overload its file sees: leveldb's `GetLengthPrefixedSlice(&input, &key)` reached memtable.cc's static and linked nothing. - A function hides a class of its name, so a call to a name both have reaches the function. - Only C++ calls: protobuf's Rust FFI calls lost their `extern` targets to the C definitions when every language went through it. Argument types read better too: a parameter named like the function it belongs to, protobuf's `std::string u64(uint64_t u64)`, was read as the function's own declarator, so `u64` looked like a `std::string`. Validated on the cgstd kit against main (627018e), every changed site classified by argument count against both targets, ~100 type-decided sites read by hand: - leveldb: 5 calls linked that linked nothing. - fmt: 283 retargeted (139 to an overload that takes that many arguments, 110 by type, 34 multi-line or defaulted); fmt's `fill_n(it, …)` on an iterator of unknown type now takes the `basic_appender` overload, right for fmt's usual iterator. - rocksdb: 101 linked, 1118 retargeted (720 by count, 339 by type). - protobuf: 29 linked, 941 retargeted (372 by count, 558 by type), e.g. the compiler helpers' `QualifiedClassName(enum_, …)` reaching the `EnumDescriptor*` overload and `Namespace(d->file())` no longer calling itself. - redis (C): byte-identical. Full suite: 7188 passed, 0 failed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…wn file can see, past another file's `static` copy (colbymchenry#2613) A C call now links to the function of its name the call's own file can see: its own, or one a header it includes defines, else one with external linkage, the best placed of them (cppFunctionOverload's C branch). Before, the name strategies took the function nearest the call; when that was another source file's `static`, isVisibleAcrossFiles dropped it and the call was left unlinked, so no call reached redis's `server.c` `mstime()` or `ustime()`. - A source file's `static` function is visible to a file that `#include`s that source file: hiredis's async.c includes dict.c, redis's ae.c its event-loop backend. - The coordinator's `resolveImport` hook falls back to matchByFilePath for a C/C++ `#include` the import resolver can't place, as resolveOneInner already does, so cppIncluders sees includes only the end of their path names: protobuf's `google/protobuf/descriptor.upb.h`, which two generated copies end in, and jemalloc's `jemalloc/internal/*.h`. Standard headers are left out: otherwise `#include <math.h>` makes jemalloc's test/math.h visible to its own include through isIncludedCppTestSuite. A/B on the cgstd kit against main 4a591ae: leveldb, fmt and rocksdb identical; redis +194 calls linked and 115 retargeted (114 to hiredis alloc.h's POSIX `static inline`s, 1 known miss: lua-cjson's fpconv_init to an inline only `#ifdef USE_INTERNAL_FPCONV` builds use); protobuf 412 upb calls retargeted from the unincluded php-upb.h amalgamation to the headers the calling file includes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…'s `#ifdef USE_INTERNAL_FPCONV` `fpconv_init`, gives way to the source file the build compiles (colbymchenry#2615) lua-cjson's fpconv.h defines `static inline void fpconv_init()` only under `#ifdef USE_INTERNAL_FPCONV` and otherwise declares it `extern` for fpconv.c to define. Nothing in redis's tree sets the flag, so its build calls fpconv.c's, but colbymchenry#2613's rule (the file's own or an included header's definition first) took the header's. c-feature-variants.ts decides whether a line is compiled only by a build that sets a flag nothing sets. It reads the conditionals around the line (cpp-macro-visibility's directiveLines, now exported): `#ifdef`/`#ifndef`, and `#if` with defined, !, &&, ||, parentheses, integers and bare flags, then `#elif` and `#else`. A flag is set nowhere when the line's own file doesn't define it, no build file from the project root down to the definition or the call names it, and no C/C++ file of their components (the tree under the nearest directory with a build file) defines it. Reserved and platform names stay unknown. cppFunctionOverload's C branch then takes a non-static, non-variant definition outside the file's tier when one exists, when every definition the file sees is such a variant, and when the call itself is compiled by the default build. A branch around both the definition and the call decides nothing: redis's quicklist.c tests call their own `static mstime` inside `#ifdef REDIS_TEST`. A/B against main dc4ccf6: leveldb, fmt, rocksdb and protobuf identical; redis 1 call retargeted, lua_cjson.c's fpconv_init() from fpconv.h to fpconv.c. Indexing time within noise (redis 10.5-11.9 s on main, 10.2-12.3 s here). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
… holder's `get()`/`value()` returns, like rocksdb's `edits.back()->MarkAtomicGroup(…)`, calls the element's method (colbymchenry#2616) A call on what a library container hands out linked to nothing: the standard library's `front()` returns nothing the index can read, and the library-receiver gate keeps the name strategies off a `std::vector`. cppLibraryElementOf reads what such a member returns, where the container's type is written: - `front()`, `back()` and `at(i)` of a sequence (std/absl, and the project sequences cppRangeElementOf already treats as such) → its element; - a library map's `at(key)` → the mapped value; - `std::stack`/`std::priority_queue` `top()`, `std::queue` `front()`/`back()` → the element; - `get()` of `std::unique_ptr`/`std::shared_ptr`/`absl::NoDestructor` → a pointer to the held type, `value()`/`value_or()` of an optional or an `absl::StatusOr` → the held type. It is asked in cppChainInnerType (a chain `recv.front().m()`) and in cppExpressionType (an `auto` local, a range, an argument), next to cppLibraryIteratorOf. A/B on the cgstd kit against main 98127e5: leveldb, fmt and redis identical; rocksdb 299 calls added, 89 retargeted (overloads picked by a typed `.get()` argument, like `test::PerThreadDBPath(env_.get(), …)`, and inherited methods on a typed element), 10 removed (guesses on what turned out to be library containers) and 56 confidence-only; protobuf 7 added and 16 retargeted (cast helpers off their `std::shared_ptr` overloads, `Add` off a deleted one). Every site was joined with the element type an instrumented arm logged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…DynamicCastMessage(const MessageLite*)` and `DynamicCastMessage(MessageLite*)`, a call reaches the one C++ picks (colbymchenry#2618) Overload fit by argument type (cppArgumentTypeChoice) scored a `const T*` parameter and its `T*` twin alike, and the one declared first won: protobuf's `DynamicCastMessage<T>(ptr.get())` on a `std::shared_ptr<Message>` took the `const MessageLite*` overload. - cppConstTwinChoice: of the best-fitting overload's twins, alike but for the `const` of a pointer or reference parameter, the one that adds `const` to the fewest arguments. - cppWrittenTypeFit: a pointer or reference to a non-const type never takes a const object, nor a reference a value a call returns (cppNamesObject tells a named object from a call's result); an object is no pointer, nor a pointer to characters a pointer to another type (or the reverse). None of that for an argument of a template parameter's type, and the pointer and `const` rules not for a parameter the function's own template parameter types (it deduces the `const`). - The argument's type keeps a `const` its declaration writes in front (`const Buffer* b`, `constexpr char key[]`), which the declarator regex leaves out; an array is a pointer to its element; `&ref` is a pointer to the referee; cppLibraryElementOf keeps a `const` in a holder's template argument (`std::shared_ptr<const Message>`). - Template headers are read 8 lines up, not 3 (fmt's `join`). A/B on the cgstd kit against main 0893606: leveldb and redis identical; fmt 14, rocksdb 25 and protobuf 194 calls retargeted, each triaged against C++'s choice (const twins, objects and arrays off the wrong pointer overloads, temporaries to `T&&`).

Merge colbymchenry/codegraph main 1981354 into fork/consolidated. The fork resolves references in the Rust kernel, so the TypeScript resolver files upstream changed here stay deleted: name-matcher.ts, cpp-includers.ts, cpp-macro-visibility.ts, cpp-namespaces.ts and cpp-type-aliases.ts, plus upstream's new c-feature-variants.ts, which builds on cpp-macro-visibility.ts. Their upstream versions are the specification for the native ports that follow this commit. Extraction follows upstream: c-cpp.ts, cpp-brace-scopes.ts, the new cpp-macro-methods.ts and the parse-worker and tree-sitter changes merge as written. The kernel's C++ naming takes upstream's explicit-specialization names (ccpp/names.rs), and the callback synthesizer reads specialization arguments through a new src/resolution/cpp-specializations.ts, since its upstream home was name-matcher.ts. CHANGELOG.md is rebuilt with scripts/changelog-reconcile.mjs, keeping the fork's earlier removal of upstream's VB.NET and CRLF store entries and taking upstream's newer wording of the Go standard-library-package entry.
…nt access Port upstream colbymchenry#2576, colbymchenry#2579, colbymchenry#2598, colbymchenry#2601, colbymchenry#2602 and colbymchenry#2616 to the native C++ receiver typing. A call now reads its receiver's type through: - `->` on a container's iterator, `it->data()` on a `std::deque<Slice>::const_iterator`, including a project container's own iterator alias and an `auto` iterator from `begin()` or `find()`; - a dereference, `(*it)->Visit()` and `(*it).Weight()`; - a map iterator's `->second` and `->first`, and a pair's members; - subscripts of arrays, pointers, standard sequences and maps, and a project class's `operator[]`; - a standard container's accessors, `front()`, `back()`, `at()`, `top()`, and the iterator the standard algorithms return. An element of a library type, or of the calling template's own parameter, is refused rather than matched by name, as before.
… unwritten `RunAll` in cpp-iterator-arrow and `Rep::Get` in cpp-map-iterator-calls call through an element only a class template's own `operator*` or `operator->` names. The fork leaves such calls unlinked instead of matching the method by name (README, "About this fork"), so both expect the call that is written out and nothing for the other.
…ough namespace aliases and macros Port upstream colbymchenry#2567, colbymchenry#2568 and colbymchenry#2569 to the native C++ receiver typing: - a receiver's method is looked up on the class its type names, anchored at the global scope, so `::upb::Arena& a` inside `namespace hpb` calls `upb::Arena::Fuse`, not `hpb::upb::Arena::Fuse`; - a type written through a namespace alias another file declares is followed: protobuf hpb's `backend::Arena` under `namespace backend = hpb::internal::backend::upb;`. Of a file's alternative aliases for one build or another, the first is taken; - a namespace a macro stands for is the project's under either name: `rocksdb::DB` reaches the `ROCKSDB_NAMESPACE::DB` the index holds, and `ROCKSDB_NAMESPACE::Cache` a class declared in `namespace rocksdb`; - a class whose methods alone are indexed, protobuf's `DescriptorProto`, is called through the method its written name qualifies.
…type is not readable A member of a template parameter (`typename PolicyT::Payload`) and a receiver declared only in another function give the call no type to read. Upstream matches the method by its name; the fork leaves such calls unlinked (README, "About this fork").
…r type Port upstream colbymchenry#2573. `SkipList<Key, Comparator>::Iterator iter` is the skip list's own `Iterator`, written with `typename` in a template or through a pointer too; the type was cut at its template arguments and looked up as `SkipList`. A library template's member type is the library's (`std::vector<int>::iterator`), except a container's `value_type` or `reference`, a smart pointer's `element_type` and a map's `mapped_type`, which name its element.
Port upstream colbymchenry#2612. A call to a function outside a class took whichever same-named function the name strategies ranked first, by where it is. Exact-name, qualified-name (global, scoped, exact and partial) and macro-namespace matching now keep their choice of function and then let the call's arguments pick among its overloads: the functions of its qualified name the call's file can see, by count and string literals, then by the types the arguments have. A qualified call no longer needs a single candidate when the candidates are one function's overloads. An overload only another source file sees, such as its `static`, never competes, and a function hides a struct of its name (`sys::stat(path, &st)`). Macro-namespace calls that fit alike by count are told apart by type and stay unlinked only when the types tie too.
…category fit Port upstream colbymchenry#2618 to the native overload choice. An argument's type now carries whether it is const and whether it names an object: - a const object never binds a non-const pointer or reference, and a value a call returns never binds a non-const reference; - an object never converts to a pointer, and characters never to a non-void pointer, except to an overload's own template parameter; - of two overloads that differ only in an added `const`, the call takes the one its argument's constness matches. A range-for element of a `const` container keeps the `const`.
…now read Four fork tests asserted a refusal the reconciled upstream behavior replaces: - a subscript result's overload set, `j[0].dump()` and `j[0].dump(1)`, is decided by argument count once the subscript reads `Json&` (colbymchenry#2602); - a macro-namespace overload set, `choose(1)`, is decided by the literal's type (colbymchenry#2612); a call whose argument type can't be read still declines; - `std::vector<Slice>::value_type` is the element Slice (colbymchenry#2573), and `auto buf = caches[0]` on a `Cache*` is a Cache (colbymchenry#2602), as upstream's own version of the library-type test now expects.
Port upstream colbymchenry#2613. A C call now reaches the function of its name the call's file sees, its own or one a header it includes defines, else one with external linkage, the best placed of them; before, the name strategies took the nearest one, and when that was another source file's `static` the call was left unlinked. - A source file's `static` function is visible to a file that includes it by any path the include writes (hiredis's async.c includes `deps/hiredis/dict.c`). - An include matched by the end of its path never places a standard header: `<math.h>` is not a project's `test/math.h`.
…iles Port upstream colbymchenry#2615 (c-feature-variants.ts) as resolve/c_feature_variants.rs. When every definition a C call's file sees is compiled only by a build that sets a flag nothing in the project sets, the call reaches a definition with external linkage that the build without the flag compiles: lua-cjson's fpconv.h defines `fpconv_init` under `#ifdef USE_INTERNAL_FPCONV`, and redis's build calls fpconv.c's. A flag is set when the definition's file defines it, a build file from the project root down names it, or a C file of its component defines it. A compiler or platform macro, and any test other than `defined`, flags, integers, `!`, `&&`, `||` and parentheses, stays unknown. A call compiled only with such a flag keeps its file's own definition.
…ters from its expansion Port the resolver half of upstream colbymchenry#2605. A method a macro of its file defines, like protobuf's `PROTOBUF_DEFINE_ACCESSOR(FieldDescriptor, number, int)`, carries its expanded head as its signature; its source position is the invocation, which spells neither its return type nor its parameters. The receiver typing now reads the return type, and the overload choice the parameters, from that head, and such a method is never taken for a deleted overload.
…rguments name Port the resolver half of upstream colbymchenry#2609 as resolve/cpp_specializations.rs. An explicit specialization is now named after its template, so a call meets both among a name's candidates. Wherever the resolver picks among C++ candidates (exact, qualified, global, partial, fuzzy and macro-namespace matching, a typed receiver's members and a chain's, the implicit-this walk and its bases): - a call that writes template arguments reaches the specialization written with the same ones, spacing aside or qualified further on one side, else the template or an ordinary overload, else nothing; - a call that writes none reaches a specialization only when nothing else has the name; - a class's own member template, specialized but none for these arguments, ends the lookup there instead of falling to a base's namesake.
…erences - README: the fork contains upstream main through 1981354; the C++ row on types the resolver cannot read now names an iterator's element and a map's key or value that a class template writes with its parameter. - CHANGELOG: drop the older copy of the C++ `->` entry that upstream's expanded one replaces, keeping the fork's "left unlinked" wording for a class derived from something that can't be followed; drop the string literal entry again (the fork already behaved that way before this merge); add one fork entry for the calls the native resolver leaves unlinked where upstream matches the method by its name alone.

…declares inside a namespace The method's owner came from the written qualifiers alone, so it never matched the class declaration's owner, which includes the enclosing namespaces. The class's default arguments were dropped and a call that omits them did not link. The owner now comes from the qualified name.

…ts key A receiver declared as `std::map<Key, Value>::value_type` was read as its first template argument, the way a sequence's `value_type` is its element, so `entry.swap(other)` linked to `Key::swap`. A map's `value_type` (and `reference`, `const_reference`) is a `std::pair` of the key and the value: a library type, so the call stays unlinked. A sequence's `value_type` is still its element.
