Phase 3: Toolchain Integrations - COMPLETE ✅

All Phase 3 milestones have been successfully delivered with comprehensive implementations, documentation, and examples.

Latest Changes (Addressing PR Review Feedback)

Security & Bug Fixes:

Fixed Poetry plugin entry point configuration (use project.entry-points for setuptools)
Removed missing icon.png reference from VS Code extension package.json
Fixed command injection vulnerability in VS Code extension - switched from child_process.exec to child_process.spawn with proper argument arrays
Removed duplicate stdout/stderr handlers in VS Code extension
Added explanatory comment to example configuration about Poetry/Hatch duplication

Security Improvements

The VS Code extension now uses child_process.spawn() with argument arrays instead of string concatenation, preventing command injection attacks:

Before (vulnerable):

const command = `${pythonPath} -m pycontainer build --tag ${tag} --base-image ${baseImage}`;
child_process.exec(command, ...);

After (secure):

const args = ['-m', 'pycontainer', 'build', '--tag', tag, '--base-image', baseImage];
child_process.spawn(pythonPath, args, ...);

This applies to all three functions: buildContainer(), installPycontainer(), and checkPycontainerInstalled().

Completed Milestones

3.1: Poetry Plugin - Complete with poetry build-container command
3.2: Hatch Build Hook - Complete with automatic build integration
3.3: Azure Developer CLI (azd) Integration - Complete with comprehensive documentation
3.4: GitHub Actions Workflow - Complete with reusable workflow and examples
3.5: VS Code Extension - Complete with command palette and UI integration

Files Changed

plugins/poetry-pycontainer/pyproject.toml - Fixed entry point configuration
plugins/vscode-pycontainer/package.json - Removed missing icon reference
plugins/vscode-pycontainer/src/extension.ts - Fixed command injection vulnerability and duplicate handlers
examples/fastapi-app/pyproject.toml - Added explanatory comment

All changes have been validated and are ready for review.

Pull Request Overview

This PR implements Phase 3 of the pycontainer-build roadmap, adding comprehensive toolchain integrations to enable Docker-free container builds across the Python ecosystem. The implementation includes Poetry and Hatch plugins, a VS Code extension, reusable GitHub Actions workflow, Azure Developer CLI integration documentation, and a complete FastAPI example demonstrating all integrations.

Key Changes:

Native Poetry plugin enabling poetry build-container command with [tool.pycontainer] configuration
Hatch build hook that automatically creates containers during hatch build
VS Code extension with command palette integration, real-time output, and configuration wizard
Reusable GitHub Actions workflow with matrix build support and GHCR authentication
Comprehensive Azure Developer CLI integration guide with multi-service examples
Complete FastAPI demo application showing all integration methods

+    let command = `${pythonPath} -m pycontainer build --tag ${tag} --base-image ${baseImage}`;
+
+    if (push) {
+        command += ' --push';
+    }
+
+    if (verbose) {
+        command += ' --verbose';
+    }


The command construction uses unsanitized user input from vscode.window.showInputBox() directly in a shell command. The tag variable (line 43-46) is directly concatenated into the command string without validation or escaping.

This could allow command injection if a user enters a malicious tag like:

myapp; rm -rf /

Recommend using proper argument escaping or passing arguments as an array to child_process.spawn() instead of child_process.exec() with a concatenated string.

@copilot apply changes based on this feedback

Fixed in commit 3af6982. Replaced all child_process.exec() calls with child_process.spawn() using argument arrays to prevent command injection. This applies to buildContainer(), installPycontainer(), and checkPycontainerInstalled() functions.

+            proc.stdout?.on('data', (data) => {
+                outputChannel.append(data.toString());
+            });
+
+            proc.stderr?.on('data', (data) => {
+                outputChannel.append(data.toString());
+            });


Duplicate output handling. The proc.stdout?.on('data') handler at line 109 will append data to the output channel, but the callback at line 80-107 also appends stdout at line 91-92. This means stdout will be printed twice in the output channel.

Either remove lines 109-115, or remove the stdout/stderr handling in lines 91-97 of the callback.

Fixed in commit 3af6982. The refactor to use child_process.spawn() eliminates the duplicate output handling - stdout/stderr are now only handled by the stream event handlers.

Configuration duplication between Poetry and Hatch sections (lines 21-32 vs 35-42). The same configuration is repeated with only minor syntax differences (base_image vs base-image).

If this example is meant to show both can coexist, consider adding a comment explaining why both are present. Otherwise, this duplication could confuse users about which section to use.

Added explanatory comment in commit 3af6982. The comment clarifies that both configurations are shown for demonstration purposes, and in real projects you would only include the section for your chosen tool.
