From 0fae68dbec724de04eae2d048f3b9e3496405307 Mon Sep 17 00:00:00 2001 From: Joe Esquibel Date: Fri, 21 Aug 2026 09:59:06 -0400 Subject: [PATCH] Fix cpp class_start forward-declaration false positive (closes #2011) The tree-sitter walker fix in the previous commit surfaced this as a real CI regression in tests/tree_sitter_accuracy_baseline_cpp.json (found_classes' denominator, real_classes, correctly dropped once the walker no longer counted forward declarations -- exposing that GitGalaxy's own class_start had the identical bug, previously masked by both sides agreeing on the same wrong answer). Fixed rather than left filed, since the regression made the gap impossible to defer further. A naive copy of C's existing _CLASS_START_REQUIRES_BODY_ANCHOR flat lookahead (stops at the first {/;/,/)/=) is unsafe for cpp: C++ multiple inheritance (`class Foo : public A, public B {`) hits the lookahead's own comma stop-char before the real `{`, falsely excluding a legitimate class definition -- confirmed via direct regex testing before this fix was written. Fixed instead with _cpp_class_has_body(), a depth-aware scanner (paren/ bracket/angle-bracket, same style as the existing _dart_scan_terminator/ _count_top_level_args helpers) that correctly walks through an inheritance clause's own top-level commas and template args before checking for a real body opener. Verified via 11 hand-built regression cases (multi-inheritance, templated bases, the pre-existing type-use-in-declarator-list protection), the full 122-test cpp extraction gauntlet, and crucible_check.py against the full ~80-repo corpus (zero golden-master diff -- confirmed via a direct DB query that this is because the golden master's audit report only exposes the raw class_start signal count, not the named-class list this fix touches, not because the fix is a no-op). Regenerates the cpp tree-sitter-accuracy baseline (found_classes/real_classes 171->65, both now matching cleanly -- class recall 87.1% -> 100.0%) and the tri-comparison ledger/chart/docs to reflect the shape no longer reproducing.

Fixed in this session (`_QUALIFY_NAME_WITH_SCOPE`, `_cpp_qualified_name_candidates`, `--pattern-length-limit=0`, all in ctags_reader.py) by re-joining name+scope from ctags' own tag data, gated on the literal qualified text actually appearing in the tag's verbatim source line so an ordinary in-class-body method (never qualified in source) isn't wrongly qualified too. This alone resolved ~1000 of the original 1097 occurrences. (2) The remainder (105 after the fix, dominated 10/10 sampled by the literal name `OPCODE`) is a genuine, different cause: godot/gdscript_vm.cpp's bytecode interpreter uses `#define OPCODE(m_op) case m_op:` -- a macro invocation used as a switch-case label, not a function call. Both GitGalaxy's func_start regex AND tree-sitter's cpp grammar independently misparse the repeated `OPCODE(OP_X) { ... }` shape as if it were a function definition named `OPCODE`; ctags correctly does not.

both correct. init_domain (module_initialize_real.F:41, `SUBROUTINE init_domain ( grid )`) genuinely takes 1 parameter. GitGalaxy's own args regex correctly matches '( grid )' when tested in isolation against the real declaration line -- the bug is upstream of the args regex entirely: fortran's func_start regex's optional return-TYPE-prefix group (`(?:INTEGER|REAL|...)[A-Za-z0-9_ \t\n&*,()=:]{0,40}?`) allows up to 40 characters including newlines between the TYPE keyword and the following FUNCTION/SUBROUTINE/etc keyword, with no requirement that they belong to the same statement. In this file, an unrelated, already-terminated `INTEGER :: internal_time_loop` declaration sits ~30 characters (4 blank lines) before `SUBROUTINE init_domain`, so the regex's own match.start() lands on that earlier, unrelated line instead of the real declaration -- corrupting every downstream computation anchored to it (start_line, body span, and -- since #1973's fix correctly bounds the args search to the label's OWN statement span -- the args search window too, which can no longer reach the real '( grid )' text several lines later). Filed as #1982 (not yet fixed).

This shape surfaces the SECOND manifestation, in a different function than the first: `_matching_paren_end` (gitgalaxy/core/detector.py:3675-3703) has NO lifetime guard at all (unlike _count_top_level_args's broken-but-present one). A lifetime tick makes its self-containment check falsely fail, falling through to the comma/whitespace-split fallback meant for Lisp/Scheme/Shell (~line 4296) -- for single-parameter signatures with a lifetime and no comma this OVER-counts (opposite direction from the sibling shape's under-count), for multi-param signatures it under-counts via the same swallowed-closing-paren mechanism.
