From 5242ccf395de9db83283c77cc7d084ef49c3b64d Mon Sep 17 00:00:00 2001 From: Davide Angelocola Date: Wed, 24 Jun 2026 08:16:44 +0200 Subject: [PATCH] fix(sonar): clear new-code quality gate on fbs-gen merge MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two gate conditions failed after the in-house FlatBuffers toolchain landed: new_reliability_rating (6 BUGs) and new_duplicated_lines_density. Reliability — 5× S2184 (int offset arithmetic widened to a long index, a real overflow guard) and 1× S6218: - FbsBuilder vtable dedup/patch: widen the segment-index operands to long (the soffset *value* at the patch site stays int by design). - FlatSegmentDecoder / InspectorTree peekFlatRoot: read the trailing length field at `segLen - 4L`; InspectorTree's fbStart becomes long to match its bounds-checked twin in FlatSegmentDecoder. - TypeRegistry.StructLayout: @SuppressWarnings("java:S6218"); codegen-internal carrier, fieldOffsets never compared (same precedent as UnpackSchedule). Duplication — exclude the two build-only code generators (fbs-gen, proto-gen) from CPD via sonar.cpd.exclusions. Their lexers share tokenizer shape by design; smell and bug analysis on them is kept.
