### Manual golangci-lint (Optional)
### Manual golangci-lint
While golangci-lint runs automatically via prek, you can also run it manually:
```bash
# Use the same logic as the pre-commit hook (recommended)
./.golangci-lint-hook.sh
# Or manually specify a base reference
# If you have upstream remote configured (recommended)
golangci-lint run --new-from-rev=upstream/main --timeout=5m --fix
# If you only have origin remote
golangci-lint run --new-from-rev=main --timeout=5m --fix
```
The `.golangci-lint-hook.sh` script automatically finds where your branch diverged from the main branch by checking `upstream/main`, `origin/main`, or `main` in that order.
**Important**: Always use `--new-from-rev` to only lint changed files. This prevents formatting the entire repository and keeps changes focused on your actual modifications.
### Skipping Hooks (Not Recommended)

- Tests generate ~100MB of logs per run in `control_logs/`
- Clean environment before each test: `sudo rm -rf control_logs/202* && docker system prune -f`
### Full Matrix Testing
Some integration tests support **full matrix mode** that tests all combinations of test dimensions. This is critical for comprehensive validation but can take up to 2 hours to complete.
**Example: TestAutoApproveMultiNetwork Full Matrix**
```bash
# Set GOPATH to avoid environment issues
export GOPATH=$HOME/go
# Enable full matrix mode and run with generous timeout
HEADSCALE_INTEGRATION_FULL_MATRIX=1 go run ./cmd/hi run "TestAutoApproveMultiNetwork" --timeout=7200s
```
**Full Matrix Dimensions:**
- **Base scenarios (6):** All combinations of:
- Auth methods: `authkey`, `webauth`
- Approver types: `tag`, `user`, `group`
- **Policy modes (2):** `database`, `file`
- **Advertisement timing (2):** `advertiseduringup-true`, `advertiseduringup-false`
- **Total combinations:** 6 × 2 × 2 = **24 tests**
**Default (minimal) mode:** Runs only 3 representative tests covering all dimensions:
- `authkey-tag-advertiseduringup-false-pol-database`
- `webauth-user-advertiseduringup-true-pol-file`
- `authkey-group-advertiseduringup-false-pol-file`
**Full Matrix Requirements:**
- **Time:** Up to 2 hours for complete execution
- **Disk space:** ~2-3GB for all test artifacts
- **Environment:** Clean Docker state before starting
- **Timeout:** Use `--timeout=7200s` (2 hours) minimum
**When to use full matrix:**
- Before major releases or merges to main
- After changes to route management, ACL evaluation, or policy engine
- When debugging flaky tests or cross-scenario issues
- For comprehensive validation of tags-as-identity changes
### Test Artifacts Location
All test runs save comprehensive debugging artifacts to `control_logs/TIMESTAMP-ID/` including server logs, client logs, database dumps, MapResponse protocol data, and Prometheus metrics.
