Description

The goal was to document the script's functionality, logic flow, and requirements without affecting its execution.

Technical Overview

After researching and analyzing the script's logic, I have documented:

  • The Workflow: How the script fetches the upstream source of truth to compare changes.
  • The State Machine: How it tracks the "Safe Zone" ([Unreleased]) versus the "Danger Zone" (Old versions) using context flags.
  • Validation Logic: A breakdown of how entries are categorized into "correctly placed," "orphan," or "wrong release" buckets.
  • Requirements: Necessary environment variables ($GITHUB_REPOSITORY), permissions, and file dependencies.

Key Documentation Points

  • Execution & Goal: Describes when the script runs and its purpose.
  • Detailed Logic Flow: Breaks down the 5-step process from network fetch to final result.
  • Environment & Permissions: Lists everything needed for the script to run successfully.

Note: This docstring was crafted based on a manual review of the script logic to ensure it serves as a helpful guide for future maintainers.

Fixes #1337

77-89: Missing required validation for GITHUB_REPOSITORY environment variable.

Line 88 uses ${GITHUB_REPOSITORY} without first validating that it's set. As per coding guidelines, scripts MUST validate all required environment variables before use.

🔎 Proposed fix
 CHANGELOG="CHANGELOG.md"
 
+# Validate required environment variables
+if [[ -z "${GITHUB_REPOSITORY:-}" ]]; then
+    echo -e "${RED}❌ Error: GITHUB_REPOSITORY environment variable is not set${RESET}"
+    exit 1
+fi
+
 # ANSI color codes
 RED="\033[31m"

As per coding guidelines, this is a MUST requirement for production-grade automation scripts.

89-89: LGTM! Changelog entry is accurate and properly placed.

The entry correctly documents the documentation enhancement under the [Unreleased] > Changed section with appropriate issue reference.

Note: The static analysis hint about capitalizing "github" is a false positive—lowercase is correct when referring to the .github/ directory path.

3-76: Excellent documentation! Comprehensive and well-structured.

The inline documentation provides clear explanations of:

  • Execution context and triggers
  • Goals and validation logic
  • Step-by-step flow (both conceptual and technical)
  • Dependencies, permissions, and return codes

This will greatly help future maintainers understand the script's behavior.

87-89: Validate required environment variable before use.

The script uses $GITHUB_REPOSITORY on line 88 but doesn't validate it exists. Per coding guidelines, scripts MUST validate all required environment variables.

🔎 Proposed fix

Add validation before line 87:

+# Validate required environment variables
+if [[ -z "${GITHUB_REPOSITORY:-}" ]]; then
+    echo -e "${RED}❌ ERROR: GITHUB_REPOSITORY environment variable is not set.${RESET}"
+    exit 1
+fi
+
 # Fetch upstream
 git remote add upstream https://github.com/${GITHUB_REPOSITORY}.git
 git fetch upstream main >/dev/null 2>&1

Based on coding guidelines.

3-76: Excellent documentation!

The comprehensive inline documentation significantly improves script maintainability by clearly explaining:

  • Execution context and triggers
  • Goal and purpose
  • High-level and detailed technical flow
  • State machine logic (Safe Zone vs. Danger Zone)
  • Required environment variables, dependencies, and permissions
  • Return codes and failure scenarios

This is exactly the kind of documentation that helps future maintainers understand complex validation logic.


77-85: LGTM!

The scaffolding initialization is clean and well-organized:

  • Clear constant for the changelog path
  • Standard ANSI color codes for user-friendly output
  • Proper initialization of the failure flag
CHANGELOG.md (1)

89-89: Minor capitalization: use "GitHub" instead of "github".

The proper noun should be capitalized consistently throughout the documentation.

🔎 Proposed fix
-- Added comprehensive documentation to the PR changelog check script (`.github/scripts/pr-check-changelog.sh`) to clarify behavior, inputs, permissions, and dependencies [(#1337)]
