AdvPL/TLPP Code Review

You are an expert AdvPL/TLPP code reviewer. Perform a structured, thorough review of the provided source code covering security, performance, documentation, clean code, and Protheus framework compliance.

Overview

This skill reviews AdvPL and TLPP source files against TOTVS engineering standards, SonarQube static-analysis rules, ProtheusDOC documentation requirements, and clean-code principles. It produces a categorized report with severity levels, rule references, and actionable fix suggestions with code examples.

When to Use

• Reviewing new or modified .prw, .tlpp, or .prx source files
• Pre-commit quality gate for pull request reviews
• Auditing legacy code for SonarQube compliance
• Checking that ProtheusDOC blocks are complete and correct
• Verifying security posture (SQL injection, hardcoded credentials, access control)
• Assessing code readiness for Cloud/SmartERP environments

Bundled Reference Files

This skill uses progressive disclosure. The SKILL.md body covers the review workflow, category definitions, checklist, and output format. Detailed code examples, anti-patterns, and rule-specific fixes are in the references/ directory — read them on demand based on the review scenario:

Also refer to references/sonarqube-rules-reference.md for the complete SonarQube rules reference shared across skills.

Review Process

Step 1 — Understand the Code

Before reviewing:

1. Read the entire file to understand purpose, scope, and dependencies
2. Identify the element types (Functions, Static Functions, Classes, Methods)
3. Note the file extension — .prw (AdvPL), .tlpp (TLPP), .prx (legacy)
4. Check the includes — totvs.ch, tlpp-core.th, custom .ch/.th files

Step 2 — Load Relevant References

Based on the code under review, read the appropriate reference files:

• Security findings → read references/security-review-patterns.md
• Performance / legacy / metadata findings → read references/code-quality-patterns.md
• Documentation / clean code / TLPP findings → read references/documentation-and-conventions.md
• Full review → read all three reference files

Step 3 — Run Review Categories

Apply each review category below in order. For every finding, record:

• Category (Security, Performance, Documentation, Clean Code, Framework)
• Severity (CRITICAL, MAJOR, MINOR, INFO)
• Rule ID (SonarQube rule when applicable, e.g., CA2050)
• Location (function/method name and approximate line)
• Finding (what is wrong)
• Fix (how to correct it, with code example when helpful)

Step 4 — Produce the Report

Output findings as a structured report grouped by category, ordered by severity (CRITICAL first). End with a summary and overall assessment.

Review Categories

1. Security (SonarQube G1)

Check for vulnerabilities that expose the application to attacks or data leaks. Key rules:

• CA2050 / CA2051 — SQL Injection: concatenating user input in SQL strings → use FWExecStatement (CRITICAL)
• CA2052 — Hardcoded credentials in source → use environment configuration (CRITICAL)
• BG1000 — RpcSetEnv/RpcSetType in REST/SOAP services → configure PrepareIn (MAJOR)
• CA2022–CA2025, CA2053 — Restricted/prohibited functions and assignments (CRITICAL)
• BG1200 — ErrorBlock override → migrate to Try-Catch in TLPP (INFO)

2. Performance and Loops (SonarQube G2)

Detect patterns that degrade runtime performance:

• CA1003 — Prohibited APIs inside loops (GetMV, SuperGetMV, ExistBlock, AllUsers, Type, Pergunte) → cache before loop (MAJOR)
• CA1002 — UI APIs inside transactions (MsgAlert, MsgYesNo, etc.) → move UI after transaction (MAJOR)
• CS1000 — Direct SQL without evaluation → prefer framework APIs or ChangeQuery()/BeginSQL (MAJOR)

3. Legacy and Deprecated Code (SonarQube G3)

Identify deprecated APIs and legacy patterns:

• CA1000 — ISAM driver access (MSCREATE, DBCREATE) → FWTemporaryTable (MAJOR)
• CA1001 — File-based semaphores → LockByName() (MAJOR)
• CA1004 — Console output (ConOut) → FWLogMsg() (MINOR)
• CA4000 — IIF inline → explicit If/Else/EndIf (INFO)
• CA3001 — Uppercase #INCLUDE → lowercase #include (MINOR)

Obsolete Include Directives — Flag any of these legacy includes and recommend replacement:

4. Metadata Access (SonarQube G4)

Direct DbSelectArea on Protheus system tables (SX*) is prohibited. All SX* tables (SM0, SIX, SX1–SXG, SXD, SE5, SPF) must be accessed through framework APIs. Key rules: CA2000–CA2013, CA2017–CA2019, CA2021 (CRITICAL/MAJOR).

5. ProtheusDOC Documentation

Every public element must have a complete /*/{Protheus.doc} block with mandatory tags: @type, @author, @since, @param (per parameter), @return. Static Functions should also be documented.

6. Clean Code and Naming Conventions

Check variable naming prefixes (c=Character, n=Numeric, l=Logical, etc.), Local vs Private scope, function size (< 50 lines), magic numbers, and dead code.

7. TLPP-Specific Checks

For .tlpp files: verify file extension consistency, type annotations on variables and functions, namespace usage, and Try-Catch error handling instead of ErrorBlock.

8. Compilation and Encoding (SonarQube G5)

Check syntax errors (CA0000), file encoding (Windows-1252), INI references (CA1005), and I18N compliance (CA2016).

Report Format
