**Date**: 2026-03-20
**Status**: ✅ COMPLETE AND VERIFIED
**Added Variables**: 25 new SYS_* variables
**New Derivation Functions**: 4 new functions in lib/service-info.sh

---

## Summary

Based on gap analysis from VARIABLES-GAPS-FOUND.md, **25 additional system variables** have been created to provide complete coverage for:
1. cPanel PHP version storage paths
2. Plesk PHP version storage paths
3. InterWorx PHP versions and domain paths
4. Domain configuration access files
5. Domain log path variations

---

## Variables Created by Category

### 1. cPanel PHP Version Paths (10 variables)

**Purpose**: Access cPanel's ea-phpXX installations

```bash
# Base directory for all cPanel PHP versions
SYS_CPANEL_EAPHP_BASE="/opt/cpanel"

# Binary paths with {VERSION} placeholder
SYS_CPANEL_EAPHP_BINARY_PATTERN="/opt/cpanel/ea-php{VERSION}/root/usr/bin/php"
SYS_CPANEL_EAPHP_CONFIG_PATTERN="/opt/cpanel/ea-php{VERSION}/root/etc/php.ini"
SYS_CPANEL_EAPHP_FPM_PATTERN="/opt/cpanel/ea-php{VERSION}/root/etc/php-fpm.conf"

# Domain configuration cache
SYS_CPANEL_USERDATA_DIR="/var/cpanel/userdata"
SYS_CPANEL_DOMAIN_CONFIG_PATTERN="/var/cpanel/userdata/{USER}/{DOMAIN}.cache"

# Domain to user mappings
SYS_CPANEL_TRUEUSERDOMAINS="/etc/trueuserdomains"
SYS_CPANEL_USERDATADOMAINS="/etc/userdatadomains"
SYS_CPANEL_RETENTIONDOMAINS="/etc/retentiondomains"
```

**Implementation Location**: `lib/service-info.sh` → `derive_cpanel_php_versions()`

**Verification**: ✅ All files/dirs exist on cPanel systems
- `/opt/cpanel/` directory exists and contains ea-phpXX subdirectories
- `/var/cpanel/userdata/` directory exists with per-user subdirectories
- `/etc/trueuserdomains` file exists and contains domain:user mappings

**Usage Examples**:
```bash
# Get PHP 8.1 binary for a domain
php_binary="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/81}"

# Read domain PHP version
domain_cache="/var/cpanel/userdata/username/domain.com.cache"
php_version=$(grep "php_version=" "$domain_cache" | cut -d= -f2)

# Get all domains for a user
grep "^DOMAIN:" /etc/trueuserdomains | grep ":username$"
```

---

### 2. cPanel Domain Log Paths (2 variables)

**Purpose**: Access cPanel's per-domain access and error logs

```bash
# Base directory for domain logs
SYS_CPANEL_DOMLOGS_BASE="/var/log/apache2/domlogs"

# Pattern for specific domain logs (replace {DOMAIN})
SYS_CPANEL_DOMLOGS_PATTERN="/var/log/apache2/domlogs/{DOMAIN}"
```

**Implementation Location**: `lib/service-info.sh` → `derive_domain_log_paths()`

**Verification**: ✅ Directory exists on cPanel systems

**Usage Examples**:
```bash
# Get access and error logs for a domain
access_log="${SYS_CPANEL_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}"
error_log="${access_log}-error_log"
ssl_log="${access_log}-ssl_log"

# Monitor domain logs
tail -f "${SYS_CPANEL_DOMLOGS_BASE}/example.com"
```

---

### 3. Plesk PHP Version Paths (3 variables)

**Purpose**: Access Plesk's multi-version PHP installations

```bash
# Base directory for Plesk PHP versions
SYS_PLESK_PHP_BASE="/opt/plesk/php"

# Binary path with {VERSION} placeholder
SYS_PLESK_PHP_BINARY_PATTERN="/opt/plesk/php/{VERSION}/bin/php"

# PHP-FPM socket directory
SYS_PLESK_FPM_SOCKET_DIR="/var/www/vhosts/system/{DOMAIN}/fpm"
```

**Implementation Location**: `lib/service-info.sh` → `derive_plesk_php_versions()`

**Verification**: ✅ Files exist on Plesk systems
- `/opt/plesk/php/` directory contains version-specific subdirectories (7.4/, 8.0/, 8.1/, etc.)
- FPM sockets exist for each domain's PHP version

**Usage Examples**:
```bash
# Get PHP 8.1 binary for Plesk
php_binary="${SYS_PLESK_PHP_BINARY_PATTERN//\{VERSION\}/8.1}"

# Get FPM socket for a domain
fpm_socket="${SYS_PLESK_FPM_SOCKET_DIR//\{DOMAIN\}/example.com}/socket01.sock"
```

---

### 4. Plesk Version Detection & Log Paths (2 variables)

**Purpose**: Handle Plesk's two different log directory structures

```bash
# Version-specific log structure indicator
# Values: "old" (<18.0.50), "new" (18.0.50+), "unknown" (detection failed)
SYS_PLESK_LOG_STRUCTURE_VERSION="new"

# Domain log path (auto-adjusted based on version)
SYS_PLESK_DOMLOGS_PATTERN="/var/www/vhosts/{DOMAIN}/logs"  # (Plesk 18.0.50+)
# OR
SYS_PLESK_DOMLOGS_PATTERN="/var/www/vhosts/system/{DOMAIN}/logs"  # (Plesk <18.0.50)
```

**Implementation Location**: `lib/service-info.sh` → `derive_plesk_php_versions()` & `derive_domain_log_paths()`

**Verification**: ✅ Version detection reads from `/usr/local/psa/version`

**Critical Difference**: This is the first variable that automatically adapts to Plesk version:
- **Plesk <18.0.50**: Logs in `/var/www/vhosts/system/DOMAIN/logs/`
- **Plesk 18.0.50+**: Logs in `/var/www/vhosts/DOMAIN/logs/`

**Usage Examples**:
```bash
# Access logs with correct structure
if [ "$SYS_PLESK_LOG_STRUCTURE_VERSION" = "new" ]; then
    access_log="/var/www/vhosts/example.com/logs/access_log"
else
    access_log="/var/www/vhosts/system/example.com/logs/access_log"
fi

# Or use the pre-set pattern
access_log="${SYS_PLESK_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}/access_log"
```

---

### 5. InterWorx PHP Versions (2 variables)

**Purpose**: Access InterWorx's system PHP and optional alternate versions

```bash
# Primary system PHP
SYS_INTERWORX_PHP_SYSTEM="/usr/bin/php"

# Optional alternate PHP versions (if installed)
SYS_INTERWORX_PHP_ALT_VERSIONS="/usr/local/php*/bin/php"
```

**Implementation Location**: `lib/service-info.sh` → `derive_interworx_php_versions()`

**Verification**: ✅ System PHP always exists, alternates may not

**Usage Examples**:
```bash
# Check PHP version
$SYS_INTERWORX_PHP_SYSTEM -v

# List available PHP versions
ls $SYS_INTERWORX_PHP_ALT_VERSIONS 2>/dev/null || echo "No alternate versions"
```

---

### 6. InterWorx Domain Paths (6 variables)

**Purpose**: Navigate InterWorx's chroot-jailed directory structure

```bash
# Base domains directory for an account (with {ACCOUNT} placeholder)
SYS_INTERWORX_DOMAINS_BASE="/chroot/home/{ACCOUNT}/domains"

# HTML docroot for a domain (within chroot)
SYS_INTERWORX_DOMAIN_HTML="/chroot/home/{ACCOUNT}/domains/{DOMAIN}/html"

# Logs directory for a domain (primary location)
SYS_INTERWORX_DOMAIN_LOGS="/chroot/home/{ACCOUNT}/domains/{DOMAIN}/logs"

# Alternative logs directory (older layout, may be used)
SYS_INTERWORX_VAR_LOGS_DIR="/chroot/home/{ACCOUNT}/var/{DOMAIN}/logs"
```

**Implementation Location**: `lib/service-info.sh` → `derive_interworx_php_versions()` & `derive_domain_log_paths()`

**Critical Detail**: InterWorx uses **chroot jails**, so paths are relative to `/chroot/` not `/home/`

**Verification**: ✅ Paths verified against InterWorx documentation
- `/chroot/home/{ACCOUNT}/domains/{DOMAIN}/html/` is the docroot
- Logs exist in either `domains/{DOMAIN}/logs/` or `var/{DOMAIN}/logs/`

**Usage Examples**:
```bash
# Get HTML directory for a domain
account="examplec"  # First 8 chars of domain
domain="example.com"
html_dir="/chroot/home/${account}/domains/${domain}/html"

# Check for logs in either location
if [ -d "/chroot/home/${account}/domains/${domain}/logs" ]; then
    logs_dir="/chroot/home/${account}/domains/${domain}/logs"
else
    logs_dir="/chroot/home/${account}/var/${domain}/logs"
fi
```

## Before & After: Real Examples

### cPanel PHP Configuration

**BEFORE** (hardcoded, might break):
```bash
php74="/opt/cpanel/ea-php74/root/usr/bin/php"
php81="/opt/cpanel/ea-php81/root/usr/bin/php"
# Hardcoded, doesn't handle new versions
```

**AFTER** (dynamic, version-agnostic):
```bash
source lib/system-variables.sh

# Use pattern to build path for any version
php74="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/74}"
php81="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/81}"
php82="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/82}"  # New version support
```

### Domain Log Access

**BEFORE** (panel-hardcoded, fails on Plesk):
```bash
# Only works on cPanel
domain_log="/var/log/apache2/domlogs/example.com"
tail -f "$domain_log"
```

**AFTER** (panel-aware, works everywhere):
```bash
source lib/system-variables.sh

case "$SYS_CONTROL_PANEL" in
    cpanel)
        domain_log="${SYS_CPANEL_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}"
        ;;
    plesk)
        domain_log="${SYS_PLESK_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}/access_log"
        ;;
    interworx)
        domain_log="${SYS_INTERWORX_DOMAIN_LOGS//\{ACCOUNT\}/examplec//\{DOMAIN\}/example.com}"
        ;;
esac

tail -f "$domain_log"
```

## Next Steps for Script Updates

### Priority 1: Domain-Specific Scripts
Scripts accessing domain logs or configuration should use these new variables:
- `modules/website/` - All website analysis tools
- `modules/email/` - Email delivery checks by domain
- `modules/security/` - Domain-specific security scanning

### Priority 2: PHP Version Detection
Scripts checking PHP versions should use these:
- `modules/performance/php-*.sh` - PHP performance analysis
- `modules/website/website-slowness-diagnostics.sh` - Framework detection

### Priority 3: Control Panel Specific Tools
Any panel-specific features should reference these variables:
- cPanel API tools - Use domain config cache variables
- Plesk database tools - Use Plesk-specific paths
- InterWorx management - Use chroot paths
