### Bash Scripting Standards
## Acknowledgments
**Strict Error Handling:**
```bash
#!/bin/bash
set -euo pipefail # Always use this
```
Thank you for your contributions and for helping to improve this project!
**Function Documentation:**
```bash
# Function description
# Arguments:
# $1 - Parameter description
# $2 - Parameter description
# Returns:
# 0 - Success
# 1 - Error
function_name() {
local param1="$1"
local param2="$2"
# Implementation
}
```
**Error Handling:**
```bash
if ! some_command; then
log_error "Descriptive error message"
return 1
fi
# Use handle_error for critical operations
handle_error sudo systemctl start service
```
**Variable Naming:**
```bash
# Constants: UPPER_CASE
readonly SCRIPT_VERSION="2.0.0"
# Global variables: UPPER_CASE
DISTRO=""
CONFIG_FILE="/etc/nas_setup.conf"
# Local variables: lower_case
local username="$1"
local config_path="/tmp/config"
```
### Input Validation Requirements
**Always validate user input:**
```bash
# Use existing validation functions
local ip=$(ask_input "IP address" "192.168.1.100" "validate_ip")
local port=$(ask_input "Port" "22" "validate_port")
local username=$(ask_input "Username" "admin" "validate_username")
```
**Create new validators when needed:**
```bash
validate_custom_input() {
local input="$1"
# Validation logic
return 0 # or 1 for invalid
}
```
### Security Requirements
**All security-related changes require:**
- Security impact assessment
- Review by maintainer
- Testing in isolated environment
- Documentation of security implications
**Security best practices:**
- Never log sensitive information (passwords, keys)
- Validate all external input
- Use parameterized commands
- Implement principle of least privilege
### Testing Requirements
**Unit Tests for New Functions:**
```bash
test_new_function() {
setup_test "new_function"
# Test valid inputs
new_function "valid_input"
assert_true $? "Valid input should succeed"
# Test invalid inputs
new_function "invalid_input"
assert_false $? "Invalid input should fail"
# Test edge cases
new_function ""
assert_false $? "Empty input should fail"
}
```
**Integration Testing:**
- Test on clean VMs for each supported distribution
- Verify rollback functionality works
- Test error scenarios and recovery
- Validate performance doesn't degrade
### Documentation Standards
**Code Comments:**
```bash
# High-level function description
# Complex logic explanation
# Security considerations
# Performance notes
```
**README Updates:**
- Update feature lists
- Add new configuration options
- Update troubleshooting sections
- Include new requirements
**CHANGELOG Updates:**
```markdown

```
## 🧪 Testing Strategy
### Required Tests Before PR
1. **Unit Tests:** `./tests/unit_tests.sh` must pass
2. **Clean Installation:** Test on fresh VM of each supported distro
3. **Rollback Testing:** Verify rollback works when errors occur
4. **Performance Testing:** Ensure no performance degradation
5. **Security Testing:** Validate security implications
### Test Environment Setup
**Recommended Testing:**
```bash
# Use VirtualBox/VMware with these distributions:
- Ubuntu 22.04 LTS
- Debian 12
- Fedora 38
- Arch Linux (current)
- openSUSE Leap 15.5
# Minimum VM specs:
- 2GB RAM
- 20GB disk
- Network access
```
### Continuous Integration
Our CI pipeline runs:
- Unit tests on all supported distributions
- Integration tests with various configurations
- Security scans
- Performance benchmarks
- Documentation validation
## 🏗️ Architecture Guidelines
### Modular Design
**Library Structure:**
- Each lib file has single responsibility
- Functions are reusable across modules
- Clear interfaces between modules
- Minimal interdependencies
**Configuration Management:**
- All defaults in `config/defaults.sh`
- User config in `/etc/nas_setup.conf`
- Environment-specific overrides supported
- Validation for all configuration values
### Performance Considerations
**Efficiency Requirements:**
- Functions should complete in reasonable time
- Minimize external command calls in loops
- Use appropriate data structures
- Profile performance-critical sections
**Resource Usage:**
- Minimize memory footprint
- Clean up temporary files
- Efficient logging (avoid excessive I/O)
- Respect system resource limits
