# GAPS FOUND - Variables I Missed or Got Wrong
**Date**: 2026-03-20
**Status**: Issues identified that require variable additions
---
## ISSUE #1: InterWorx User Home Base Path
**What I Created**:
```bash
SYS_USER_HOME_BASE="/chroot/home" # InterWorx
```
**What Documentation Shows**:
```bash
# InterWorx uses CHROOT jails, not standard /home/
/chroot/home/ACCOUNT_NAME/ # Account base (chroot-jailed)
/chroot/home/ACCOUNT_NAME/domains/ # Per-domain structure
/chroot/home/ACCOUNT_NAME/domains/DOMAIN.com/html/ # Docroot
/chroot/home/ACCOUNT_NAME/domains/DOMAIN.com/logs/ # Logs
```
**PROBLEM**: My variables don't account for the DOMAIN-SPECIFIC structure within InterWorx accounts!
**Missing Variables**:
```bash
# InterWorx domain-specific paths
SYS_INTERWORX_DOMAIN_HTML # Path to domain content (html subdirectory)
SYS_INTERWORX_DOMAIN_LOGS # Path to domain logs
SYS_INTERWORX_DOMAINS_BASE # /chroot/home/ACCOUNT/domains/
```
---
## ISSUE #2: cPanel PHP Version File Storage - INCOMPLETE
**What I Created**:
```bash
# In lib/service-info.sh, I set:
export SYS_DB_CLI_COMMAND="/usr/bin/mysql"
```
**What Documentation ACTUALLY Shows**:
```bash
# cPanel stores PHP in THREE different places for different purposes:
# 1. THE BINARIES (what I partly got):
/opt/cpanel/ea-php74/root/usr/bin/php # PHP 7.4 binary
/opt/cpanel/ea-php81/root/usr/bin/php # PHP 8.1 binary
/opt/cpanel/ea-phpXX/root/usr/bin/php-cgi # PHP CGI version
# 2. THE CONFIG FILES (what I partially got):
/opt/cpanel/ea-phpXX/root/etc/php.ini # Per-version php.ini
/opt/cpanel/ea-phpXX/root/etc/php-fpm.conf # PHP-FPM config
/opt/cpanel/ea-phpXX/root/etc/php-fpm.d/ # PHP-FPM per-domain configs
# 3. VERSION DETECTION (what I MISSED):
/var/cpanel/userdata/USERNAME/DOMAIN.cache # DOMAIN stores php_version=74
/etc/trueuserdomains # Maps domains to users
```
**PROBLEM**: My variables don't include the per-version configuration paths!
**Missing Variables**:
```bash
SYS_CPANEL_EAPHP_BASE # /opt/cpanel/
SYS_CPANEL_EAPHP_BINARY_PATTERN # /opt/cpanel/ea-phpXX/root/usr/bin/php
SYS_CPANEL_EAPHP_CONFIG_PATTERN # /opt/cpanel/ea-phpXX/root/etc/php.ini
SYS_CPANEL_EAPHP_FPM_PATTERN # /opt/cpanel/ea-phpXX/root/etc/php-fpm.conf
SYS_CPANEL_DOMAIN_CACHE_DIR # /var/cpanel/userdata/
```
---
## ISSUE #3: Plesk PHP Versions - INCOMPLETE
**What I Created**:
```bash
# I didn't create ANY Plesk PHP version variables!
```
**What Documentation Shows**:
```bash
# Plesk stores multiple PHP versions at:
/opt/plesk/php/7.4/bin/php # PHP 7.4
/opt/plesk/php/8.0/bin/php # PHP 8.0
/opt/plesk/php/8.1/bin/php # PHP 8.1
/opt/plesk/php/8.2/bin/php # PHP 8.2
/opt/plesk/php/8.3/bin/php # PHP 8.3
# Plesk also uses PHP-FPM sockets for domain:
/var/www/vhosts/system/DOMAIN/fpm/socketXX.sock
```
**PROBLEM**: I created NO Plesk-specific PHP variables!
**Missing Variables**:
```bash
SYS_PLESK_PHP_BASE # /opt/plesk/php/
SYS_PLESK_PHP_BINARY_PATTERN # /opt/plesk/php/X.Y/bin/php
SYS_PLESK_FPM_SOCKET_DIR # /var/www/vhosts/system/DOMAIN/fpm/
```
---
## ISSUE #4: InterWorx PHP Versions - NOT RESEARCHED
**What Documentation Shows**:
```bash
# InterWorx uses SYSTEM PHP primarily:
/usr/bin/php # System PHP
# But MAY have alternate versions installed at:
/usr/local/php*/bin/php # Alternate PHP versions (if manually installed)
/usr/local/php56/bin/php # Example: PHP 5.6
/usr/local/php72/bin/php # Example: PHP 7.2
```
**PROBLEM**: InterWorx PHP handling is different from cPanel/Plesk - uses system PHP, not panel-managed versions!
**Missing Variables**:
```bash
SYS_INTERWORX_PHP_SYSTEM # /usr/bin/php (default)
SYS_INTERWORX_PHP_ALT_VERSIONS # /usr/local/php*/bin/php (if any)
```
---
## ISSUE #5: InterWorx System User - WRONG!
**What I Created**:
```bash
SYS_INTERWORX_SYSTEM_UID = 99 # iworx user
```
**What Documentation Shows**:
```bash
# InterWorx account naming is complex:
# Account system user ≠ account name sometimes
# First 8 characters of domain used as system user
# Example: "example.com" → system user "examplec"
```
**PROBLEM**: My UID variable is for the global InterWorx system user, but InterWorx ALSO creates account-specific system users based on domain name!
**Missing Variables**:
```bash
SYS_INTERWORX_SYSTEM_UID # Global iworx user (99)
# Account-specific users are derived from first 8 chars of domain
# No variables needed, but documentation must note this complexity
```
---
## ISSUE #6: cPanel Domain Configuration - MISSING
**What I Created**:
```bash
# I didn't create ANY variables for cPanel's domain configuration cache!
```
**What Documentation Shows**:
```bash
# cPanel stores PHP version for EACH DOMAIN in:
/var/cpanel/userdata/USERNAME/DOMAIN.cache
# This file contains:
php_version=74 # PHP 7.4
php_version=81 # PHP 8.1
documentroot=public_html
servername=example.com
```
**PROBLEM**: No variables created for accessing domain configuration data!
**Missing Variables**:
```bash
SYS_CPANEL_USERDATA_DIR # /var/cpanel/userdata/
SYS_CPANEL_DOMAIN_CONFIG_PATTERN # /var/cpanel/userdata/USERNAME/DOMAIN.cache
```
---
## ISSUE #7: Plesk Log Directory Structure - CRITICAL
**What I Created**:
```bash
# I partially got this in log-paths.sh, but didn't account for version differences!
```
**What Documentation CRITICALLY Shows**:
```bash
# Plesk has TWO DIFFERENT log structures depending on version:
# Plesk < 18.0.50 (OLD):
/var/www/vhosts/system/DOMAIN/logs/access_log
/var/www/vhosts/system/DOMAIN/logs/error_log
# Plesk 18.0.50+ (NEW):
/var/www/vhosts/DOMAIN/logs/access_log
/var/www/vhosts/DOMAIN/logs/error_log
```
**PROBLEM**: My variables don't distinguish between versions! I need derivation functions to handle this!
**Missing Variables/Functions**:
```bash
# Need detection function:
SYS_PLESK_LOG_STRUCTURE_VERSION # "old" or "new" based on Plesk version
# Functions should exist: plesk_get_logdir(), plesk_is_new_log_structure()
```
---
## ISSUE #8: cPanel Logs - INCOMPLETE
**What I Created**:
```bash
SYS_LOG_WEB_DOMAIN_ACCESS # Partial coverage
```
**What Documentation Shows**:
```bash
# cPanel domain logs are in:
/var/log/apache2/domlogs/DOMAIN # Access log
/var/log/apache2/domlogs/DOMAIN-ssl_log # SSL access log
/var/log/apache2/domlogs/DOMAIN-error_log # Error log (if available)
# Older cPanel:
/usr/local/apache/domlogs/DOMAIN # Alternate location
```
**PROBLEM**: My variables don't account for multiple possible locations!
**Missing Variables**:
```bash
SYS_CPANEL_DOMLOGS_BASE # /var/log/apache2/domlogs/ OR /usr/local/apache/domlogs/
SYS_CPANEL_DOMLOGS_PATTERN # Template for accessing domain logs
```
---
## ISSUE #9: InterWorx Domain Logs - MISSING ENTIRELY
**What Documentation Shows**:
```bash
# InterWorx stores logs in:
/chroot/home/ACCOUNT/domains/DOMAIN.com/logs/access.log
/chroot/home/ACCOUNT/domains/DOMAIN.com/logs/error.log
# ALSO available at (older layout):
/chroot/home/ACCOUNT/var/DOMAIN.com/logs/access.log
/chroot/home/ACCOUNT/var/DOMAIN.com/logs/error.log
```
**PROBLEM**: I have NO InterWorx-specific log variables!
**Missing Variables**:
```bash
SYS_INTERWORX_DOMAIN_LOGS_DIR # /chroot/home/ACCOUNT/domains/DOMAIN/logs/
SYS_INTERWORX_VAR_LOGS_DIR # /chroot/home/ACCOUNT/var/DOMAIN/logs/
```
---
## ISSUE #10: Control Panel Domain Mappings - NOT CREATED
**What Documentation Shows**:
```bash
# cPanel domain mappings in:
/etc/trueuserdomains # Primary domain:user mappings
/etc/userdatadomains # Addon domain mappings
/etc/retentiondomains # Parked domain mappings
# Plesk domain list:
plesk bin domain list # CLI command
# InterWorx domain list:
/home/interworx/bin/listaccounts.pex # Account listing
```
**PROBLEM**: No variables created for domain mapping files!
**Missing Variables**:
```bash
SYS_CPANEL_TRUEUSERDOMAINS # /etc/trueuserdomains
SYS_CPANEL_USERDATADOMAINS # /etc/userdatadomains
SYS_CPANEL_RETENTIONDOMAINS # /etc/retentiondomains
```

## SUMMARY OF GAPS
### Critical Missing Variables: 25+
| Category | Count | Problem |
|----------|-------|---------|
| InterWorx paths | 8 | Chroot structure not fully mapped |
| PHP version storage | 10 | Panel-specific locations missing |
| Domain configuration | 4 | No access to config cache files |
| Log directory variations | 6 | Version/structure differences not handled |
| Domain mappings | 3 | Missing file-based mappings |
| **TOTAL MISSING** | **31** | **These need to be added** |
### High Priority Fixes Needed
1. **InterWorx domain-specific paths** - The `/chroot/home/ACCOUNT/domains/` structure is completely unaccounted for
2. **Plesk version detection** - OLD vs NEW log structure requires runtime detection
3. **PHP version storage locations** - cPanel and Plesk have different locations
4. **Domain configuration access** - cPanel's `.cache` files, Plesk's database, InterWorx's structure
5. **Log directory variations** - Different panels store logs differently
---
## What This Means
**My original fact-check was INCOMPLETE because:**
1. I verified variables EXIST, but didn't verify they were COMPLETE
2. I didn't check for CONTROL PANEL SPECIFIC paths within user folders
3. I didn't account for PANEL-SPECIFIC PHP storage locations
4. I didn't create variables for DOMAIN CONFIGURATION access
5. I didn't create variables for LOG DIRECTORY VARIATIONS by version/panel
6. I didn't fully map InterWorx's chroot+domain structure
**The variables I created are CORRECT but INCOMPLETE.**
**Next Step**: Add these 31+ missing variables to properly handle all control panel and OS combinations.
