Added existence checks and error handling for all source commands
to prevent silent failures when dependencies are missing.
Library files (use 'return' for error):
- reference-db.sh: Added checks for 3 dependencies
- mysql-analyzer.sh: Added checks for 3 dependencies
- domain-discovery.sh: Added checks for 2 dependencies
- system-detect.sh: Added check for common-functions.sh
- plesk-helpers.sh: Added check for common-functions.sh
- user-manager.sh: Added checks for 2 dependencies
Executable scripts (use 'exit' for error):
- wordpress-cron-manager.sh: Added checks for 2 dependencies
- website-error-analyzer.sh: Added checks for 4 dependencies
Pattern: [ -f "file" ] && source "file" || { echo "ERROR" >&2; return/exit 1; }
This ensures scripts fail fast with clear error messages when
required dependencies are missing, rather than continuing with
undefined functions.
Issue: list_plesk_users() in user-manager.sh was trying to query MySQL
but the query was failing, resulting in 0 users detected on Plesk.
Fix:
1. Added plesk_list_users() to plesk-helpers.sh that uses:
- Plesk CLI: 'plesk bin client --list' (primary)
- Fallback: Scan /var/www/vhosts directories
2. Updated list_plesk_users() in user-manager.sh to:
- First try plesk_list_users() if available
- Then try MySQL query
- Last resort: directory scan
This should now detect Plesk users from either Plesk API or
filesystem fallback.
Testing: Will verify on Plesk server
