# Validating Azure Pipeline Changes

When modifying Azure DevOps pipeline files (YAML files in `build/azure-pipelines/`), you can validate changes locally using the Azure CLI before committing. This avoids the slow feedback loop of pushing changes, waiting for CI, and checking results.

## Prerequisites

1. **Check if Azure CLI is installed**:
   ```bash
   az --version
   ```

   If not installed, install it:
   ```bash
   # macOS
   brew install azure-cli

   # Windows (PowerShell as Administrator)
   winget install Microsoft.AzureCLI

   # Linux (Debian/Ubuntu)
   curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash
   ```

2. **Check if the DevOps extension is installed**:
   ```bash
   az extension show --name azure-devops
   ```

   If not installed, add it:
   ```bash
   az extension add --name azure-devops
   ```

3. **Authenticate**:
   ```bash
   az login
   az devops configure --defaults organization=https://dev.azure.com/monacotools project=Monaco
   ```

## VS Code Main Build

The main VS Code build pipeline:
- **Organization**: `monacotools`
- **Project**: `Monaco`
- **Definition ID**: `111`
- **URL**: https://dev.azure.com/monacotools/Monaco/_build?definitionId=111

## VS Code Insider Scheduled Builds

Two Insider builds run automatically on a scheduled basis:
- **Morning build**: ~7:00 AM CET
- **Evening build**: ~7:00 PM CET

These scheduled builds use the same pipeline definition (`111`) but run on the `main` branch to produce Insider releases.

---

## Queueing a Build

Use the [queue command](./azure-pipeline.ts) to queue a validation build:

```bash
# Queue a build on the current branch
node .github/skills/azure-pipelines/azure-pipeline.ts queue

# Queue with a specific source branch
node .github/skills/azure-pipelines/azure-pipeline.ts queue --branch my-feature-branch

# Queue with custom parameters
node .github/skills/azure-pipelines/azure-pipeline.ts queue --parameter "VSCODE_BUILD_WEB=false" --parameter "VSCODE_PUBLISH=false"

# Parameter value with spaces
node .github/skills/azure-pipelines/azure-pipeline.ts queue --parameter "VSCODE_BUILD_TYPE=Product Build"
```

> **Important**: Before queueing a new build, cancel any previous builds on the same branch that you no longer need. This frees up build agents and reduces resource waste:
> ```bash
> # Find the build ID from status, then cancel it
> node .github/skills/azure-pipelines/azure-pipeline.ts status
> node .github/skills/azure-pipelines/azure-pipeline.ts cancel --build-id <id>
> node .github/skills/azure-pipelines/azure-pipeline.ts queue
> ```

## Checking Build Status

Use the [status command](./azure-pipeline.ts) to monitor a running build:

```bash
# Get status of the most recent builds
node .github/skills/azure-pipelines/azure-pipeline.ts status

# Get overview of a specific build by ID
node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id 123456

# Watch build status (refreshes every 30 seconds)
node .github/skills/azure-pipelines/azure-pipeline.ts status --watch

# Watch with custom interval (60 seconds)
node .github/skills/azure-pipelines/azure-pipeline.ts status --watch 60
```

### Script Options

|--------|-------------|
| `--build-id <id>` | Specific build ID (default: most recent on current branch) |
| `--branch <name>` | Filter builds by branch name (shows last 20 builds for branch) |
| `--reason <reason>` | Filter builds by reason: `manual`, `individualCI`, `batchedCI`, `schedule`, `pullRequest` |
| `--definition <id>` | Pipeline definition ID (default: 111) |
| `--watch [seconds]` | Continuously poll status until build completes (default: 30s) |
| `--download-log <id>` | Download a specific log to /tmp |
| `--download-artifact <name>` | Download artifact to /tmp |
| `--json` | Output raw JSON for programmatic consumption |

---

## Cancelling a Build

Use the [cancel command](./azure-pipeline.ts) to stop a running build:

```bash
# Cancel a build by ID (use status command to find IDs)
node .github/skills/azure-pipelines/azure-pipeline.ts cancel --build-id 123456

# Dry run (show what would be cancelled)
node .github/skills/azure-pipelines/azure-pipeline.ts cancel --build-id 123456 --dry-run
```

### Script Options

| Option | Description |
|--------|-------------|
| `--build-id <id>` | Build ID to cancel (required) |
| `--definition <id>` | Pipeline definition ID (default: 111) |
| `--dry-run` | Print what would be cancelled without executing |

## Testing Pipeline Changes

When the user asks to **test changes in an Azure Pipelines build**, follow this workflow:

1. **Queue a new build** on the current branch
2. **Poll for completion** by periodically checking the build status until it finishes

### Polling for Build Completion

Use a shell loop with `sleep` to poll the build status. The `sleep` command works on all major operating systems:

```bash
# Queue the build and note the build ID from output (e.g., 123456)
node .github/skills/azure-pipelines/azure-pipeline.ts queue

# Poll every 60 seconds until complete (works on macOS, Linux, and Windows with Git Bash/WSL)
# Replace <BUILD_ID> with the actual build ID from the queue command
while true; do
  node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id <BUILD_ID> --json 2>/dev/null | grep -q '"status": "completed"' && break
  sleep 60
done

# Check final result
node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id <BUILD_ID>
```

Alternatively, use the built-in `--watch` flag which handles polling automatically:

```bash
node .github/skills/azure-pipelines/azure-pipeline.ts queue
# Use the build ID returned by the queue command
node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id <BUILD_ID> --watch
```

> **Note**: The `--watch` flag polls every 30 seconds by default. Use `--watch 60` for a 60-second interval to reduce API calls.

---

## Common Workflows

### 1. Quick Pipeline Validation

```bash
# Make your YAML changes, then:
git add -A && git commit -m "test: pipeline changes"
git push origin HEAD

# Check for any previous builds on this branch and cancel if needed
node .github/skills/azure-pipelines/azure-pipeline.ts status
node .github/skills/azure-pipelines/azure-pipeline.ts cancel --build-id <id>  # if there's an active build

# Queue and watch the new build
node .github/skills/azure-pipelines/azure-pipeline.ts queue
node .github/skills/azure-pipelines/azure-pipeline.ts status --watch
```

### 2. Investigate a Build

```bash
# Get overview of a build (shows stages, artifacts, and log IDs)
node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id 123456

# Download a specific log for deeper inspection
node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id 123456 --download-log 5

# Download an artifact
node .github/skills/azure-pipelines/azure-pipeline.ts status --build-id 123456 --download-artifact unsigned_vscode_cli_win32_x64_cli
```

### 3. Test with Modified Parameters

```bash
# Customize build matrix for quicker validation
node .github/skills/azure-pipelines/azure-pipeline.ts queue \
   --parameter "VSCODE_BUILD_TYPE=CI Build" \
   --parameter "VSCODE_BUILD_WEB=false" \
   --parameter "VSCODE_BUILD_ALPINE=false" \
   --parameter "VSCODE_BUILD_ALPINE_ARM64=false" \
   --parameter "VSCODE_PUBLISH=false"
```

### 4. Cancel a Running Build

```bash
# First, find the build ID
node .github/skills/azure-pipelines/azure-pipeline.ts status

# Cancel a specific build by ID
node .github/skills/azure-pipelines/azure-pipeline.ts cancel --build-id 123456

# Dry run to see what would be cancelled
node .github/skills/azure-pipelines/azure-pipeline.ts cancel --build-id 123456 --dry-run
```

### 5. Iterate on Pipeline Changes

When iterating on pipeline YAML changes, always cancel obsolete builds before queueing new ones:

```bash
# Push new changes
git add -A && git commit --amend --no-edit
git push --force-with-lease origin HEAD

# Find the outdated build ID and cancel it
node .github/skills/azure-pipelines/azure-pipeline.ts status
node .github/skills/azure-pipelines/azure-pipeline.ts cancel --build-id <id>

# Queue a fresh build and monitor
node .github/skills/azure-pipelines/azure-pipeline.ts queue
node .github/skills/azure-pipelines/azure-pipeline.ts status --watch
```

## Troubleshooting

### Authentication Issues
```bash
# Re-authenticate
az logout
az login

# Check current account
az account show
```

### Extension Not Found
```bash
az extension add --name azure-devops --upgrade
```

### Rate Limiting
If you hit rate limits, add delays between API calls or use `--watch` with a longer interval.
