Summary

Correção das issues SonarCloud introduzidas pelo merge do PR #98.

Alterações:

S2971 em src/Metar.Decoder/Entity/Value.cs e src/Taf.Decoder/Entity/Value.cs: substituído Where(...).FirstOrDefault() por FirstOrDefault(...)
S3241 em src/Taf.Decoder/ChunkDecoder/EvolutionChunkDecoder.cs: ParseEntitiesChunk agora retorna void (nenhum caller usava o retorno)
S3776 em src/Taf.Decoder/ChunkDecoder/CloudChunkDecoder.cs, VisibilityChunkDecoder.cs e EvolutionChunkDecoder.cs: extraídos métodos helpers para reduzir complexidade cognitiva
S2325 em MetarDecoder/TafDecoder: ParseStrict e ParseNotStrict mantidos como métodos de instância com [SuppressMessage] para preservar compatibilidade de API
Null check defensivo em Value.ToInt e fail-fast em ApplyDecodedData (METAR/TAF) para evitar NullReferenceException
Testes ajustados de chamadas estáticas para chamadas de instância

Validação

dotnet build MetarDecoder.sln --configuration Release OK
dotnet test tests/Metar.Decoder.Tests/ OK — 242/242 passando
dotnet test tests/Taf.Decoder.Tests/ OK — 192/192 passando

Nota: as 3 issues restantes do tipo githubactions:S7630/S1135 estão em .github/workflows e, conforme as regras de guardrail do repositório, workflows não foram alterados.

Devin Review found 4 potential issues.

devin-ai-integration · 2026-07-12T18:45:37Z

🔍 EvolutionChunkDecoder.Remaining is never set on the successful parse path

The Remaining property (src/Taf.Decoder/ChunkDecoder/EvolutionChunkDecoder.cs:38) is only assigned in the early-return path when found.Count <= 1 (line 65). On the successful path (when evolution chunks are actually parsed), Remaining retains its previous value. The caller in TafDecoder.DecodeEvolutions (src/Taf.Decoder/TafDecoder.cs:167) reads evolutionDecoder.Remaining after every Parse call. This means after a successful parse, the loop re-reads the stale Remaining from the previous iteration (or null on first success), which could cause an infinite loop or premature termination. This is a pre-existing issue (the old ParseEntitiesChunk returned the remaining string but the return value was never captured), not introduced by this PR, but the refactoring to void makes it more visible.

(Refers to lines 95-96)

+        public DecodedMetar ParseStrict(string rawMetar)
        {


🔍 ParseStrict and ParseNotStrict changed from static to instance — breaking change for external callers

Both MetarDecoder.ParseStrict/ParseNotStrict (src/Metar.Decoder/MetarDecoder.cs:77,90) and TafDecoder.ParseStrict/ParseNotStrict (src/Taf.Decoder/TafDecoder.cs:71,84) were changed from public static to public (instance). While ParseWithMode remains static, any external consumer calling MetarDecoder.ParseStrict(...) or TafDecoder.ParseNotStrict(...) as a static method will get a compile error after upgrading the NuGet package. The tests were updated to use instance calls, but downstream users won't be. This is a source-breaking change in a public API of a library.

+                            throw new MetarChunkDecoderException($"Unknown property: {obj.Key}");
+                        }


📝 Info: New MetarChunkDecoderException throw site uses message-only constructor

The new defensive check at src/Metar.Decoder/MetarDecoder.cs:174 throws new MetarChunkDecoderException($"Unknown property: {obj.Key}") using a message-only constructor. The catch block at line 135 accesses metarChunkDecoderException.RemainingMetar (line 143) to continue parsing in non-strict mode. If RemainingMetar is null from this constructor, it would assign null to remainingMetar, likely causing a NullReferenceException on the next decoder iteration. The same pattern exists in TafDecoder.cs:182. In practice this path should never be hit with the existing chunk decoders (all property keys are valid), but it's worth noting the inconsistency. The old code would have thrown a NullReferenceException from GetProperty().SetValue() instead, so the new code is arguably better — it just has a different failure mode.

📝 Info: Unused import added to CloudChunkDecoder

using System.Text.RegularExpressions; was added at src/Taf.Decoder/ChunkDecoder/CloudChunkDecoder.cs:2 but the refactored code no longer uses any regex types directly — all regex usage is in the base class TafChunkDecoder. This import is unused.
