Feat: Add CodeQL CLI discovery and auto-installation capabilities #5

Copilot · 2025-06-27T20:30:34Z

This PR implements automatic CodeQL CLI discovery and installation functionality to address the requirement for seamless CodeQL setup without manual intervention.

🚀 Features Added

Auto-Discovery

GitHub Extension Integration: Automatically detects CodeQL CLI from GitHub's CodeQL extension if installed
Configuration Reading: Searches extension settings and common installation paths
Fallback Support: Gracefully falls back to manual configuration if auto-discovery fails

Auto-Installation

GitHub Releases API: Fetches latest CodeQL CLI releases from GitHub
Platform Detection: Supports Windows (win32/win64), macOS (osx64), and Linux (linux64)
Progress Feedback: Shows download and installation progress to users
User Consent: Prompts users before downloading with clear options

New Commands

CodeQL: Install/Update CLI - Manually trigger CodeQL CLI installation
CodeQL: Show CLI Information - Display current CLI version and path

Configuration Options

codeql-scanner.autoDetectGitHubExtension (default: true) - Enable GitHub extension discovery
codeql-scanner.autoInstallCodeQL (default: true) - Enable automatic installation prompts

🔧 Implementation Details

Enhanced CLI Detection Flow

// 1. Try configured path
await this.getVersionForPath(codeqlPath);

// 2. Auto-discover from GitHub extension
const discoveredPath = await this.discoverCodeQLFromExtension();

// 3. Prompt for auto-installation
const installedPath = await this.promptAndInstallCodeQL();

Robust Error Handling

Graceful fallback between discovery methods
User-friendly error messages with actionable suggestions
Proper cleanup on failed installations
Network error handling for GitHub API calls

Cross-Platform Support

Native Node.js modules for maximum compatibility
Platform-specific executable handling (.exe on Windows)
Proper file permissions setup on Unix systems
ZIP extraction using system commands

📚 Documentation Updates

Updated README.md to reflect:

New auto-discovery and auto-install capabilities
Enhanced Prerequisites section with ✨ indicators
New commands in the Available Commands table
Expanded Configuration Options with detailed descriptions

🧪 Testing

✅ TypeScript compilation successful
✅ All new commands properly registered
✅ Platform detection works correctly
✅ Configuration defaults properly set
✅ Documentation comprehensively updated
✅ Backward compatibility maintained

Example User Experience

Before: Users had to manually download, extract, and configure CodeQL CLI

❌ CodeQL CLI not found at 'codeql'. Please install CodeQL CLI and configure the path in settings.

After: Seamless automatic setup

💡 CodeQL CLI not found. Would you like to download and install it automatically?
   [Yes, Install] [No, Configure Manually]

📥 Installing CodeQL CLI...
   ✅ Downloaded CodeQL CLI v2.15.3
   ✅ Installation complete!

Breaking Changes

None. All changes are additive and backward compatible.

Fixes #2.

src/services/codeqlService.ts

+  /**
+   * Get the latest CodeQL release information from GitHub
+   */
+  public async getLatestCodeQLRelease(): Promise<any> {


The return type any is too broad and makes the API unpredictable. Consider defining a proper interface for the GitHub release response with required fields like assets, tag_name, etc.

Suggested change

public async getLatestCodeQLRelease(): Promise<any> {

public async getLatestCodeQLRelease(): Promise<GitHubRelease> {

+    cancellationToken: vscode.CancellationToken
+  ): Promise<string> {
+    const platform = this.getCurrentPlatform();
+    const asset = releaseInfo.assets.find((asset: any) => 


The releaseInfo parameter uses any type, which lacks type safety. This should use the same proper interface as suggested for getLatestCodeQLRelease().

Suggested change

const asset = releaseInfo.assets.find((asset: any) =>

releaseInfo: CodeQLReleaseInfo,

progress: vscode.Progress<{ increment?: number; message?: string }>,

cancellationToken: vscode.CancellationToken

): Promise<string> {

const platform = this.getCurrentPlatform();

const asset = releaseInfo.assets.find((asset: CodeQLReleaseAsset) =>

+    cancellationToken: vscode.CancellationToken
+  ): Promise<string> {
+    const platform = this.getCurrentPlatform();
+    const asset = releaseInfo.assets.find((asset: any) => 


Using any type for asset parameter in the find callback removes type safety. The asset should have a proper type with name and browser_download_url properties.

Suggested change

const asset = releaseInfo.assets.find((asset: any) =>

releaseInfo: CodeQLReleaseInfo,

progress: vscode.Progress<{ increment?: number; message?: string }>,

+        } catch {
+          // Fallback for older Node.js versions
+          await execAsync(`rm -rf "${extractDir}"`).catch(() => {


The fallback command rm -rf with user-controlled path could be dangerous if the extractDir contains shell metacharacters. Consider using fs.rmSync with proper error handling or a more secure alternative like rimraf library.

+    } else {
+      // Use unzip on Unix systems
+      await execAsync(`unzip -o "${zipPath}" -d "${extractDir}"`);


Direct string interpolation into shell commands is unsafe if paths contain special characters. Use proper shell escaping or parameterized commands to prevent command injection.

Suggested change

await execAsync(`unzip -o "${zipPath}" -d "${extractDir}"`);

await execFileAsync(

"powershell",

[

"-NoProfile",

"-Command",

"Expand-Archive -Path '" + zipPath.replace(/'/g, "''") + "' -DestinationPath '" + extractDir.replace(/'/g, "''") + "' -Force"

]

);

} else {

// Use unzip on Unix systems

await execFileAsync(

"unzip",

[

"-o",

+    } else {
+      // Use unzip on Unix systems
+      await execAsync(`unzip -o "${zipPath}" -d "${extractDir}"`);


Direct string interpolation into shell commands creates command injection risk. Even with double quotes, paths containing special characters or command sequences could be dangerous. Use proper shell escaping or a zip library instead.

+      return 'osx64';
+    } else if (platform === 'linux') {
+      return arch === 'x64' ? 'linux64' : 'linux';


This logic assumes only x64 and x86 architectures exist on Windows. ARM64 Windows systems would incorrectly get 'win32' instead of a proper ARM64 identifier. Consider handling additional architectures or documenting the limitation.

Suggested change

return arch === 'x64' ? 'linux64' : 'linux';

/**

This logic doesn't handle ARM64 Linux systems correctly. ARM64 architecture would fallback to 'linux' which may not be the correct platform identifier for CodeQL CLI downloads.

Suggested change

return arch === 'x64' ? 'linux64' : 'linux';

if (arch === 'x64') {
