Developer e4bb749ddd Re-apply critical stability fixes from production to dev 
CRITICAL FIXES RE-APPLIED:
1. Safe read statements with /dev/tty redirection
   - Prevents hangs when stdin is piped or unavailable
   - Prevents SSH session termination on menu prompts
   - Gracefully returns instead of crashing

2. Error handling on all read statements
   - Read failures now return instead of exiting unexpectedly
   - Fixes crash when stdin is closed

3. SQL injection prevention in reference-db.sh
   - Database names now escaped with backticks
   - Prevents malicious DB names from breaking queries

4. Password exposure fix in reference-db.sh
   - Use MYSQL_PWD environment variable
   - Credentials no longer visible in 'ps aux' output

5. Race condition fix in temp directory creation
   - Use mktemp -d instead of mkdir -p
   - Secure permissions (0700) and unpredictable naming
   - Prevents TOCTOU attacks

TESTING RESULTS:
✓ QA script passed
✓ Multi-scanner detection verified (4 scanners)
✓ Syntax validation passed
✓ Safe input handling verified
✓ All critical functions available

Status: Ready for testing in dev branch

Developer f6fd4118e3 Phase 2 Improvements: Array safety, URL encoding, and source guards 
IMPROVEMENTS:
1. Array Safety (reference-db.sh:128-134)
   - Changed from unsafe word-splitting to proper array construction
   - Uses while loop with IFS= read for safer user enumeration
   - Prevents issues with usernames containing special characters

2. URL Encoding for Domain Checks (reference-db.sh:24-48)
   - Added url_encode() helper function
   - Encodes domain names for curl requests
   - Handles domains with special characters safely
   - Prevents curl errors on unusual domain names

3. Configurable Timeout (reference-db.sh:21)
   - Made domain check timeout configurable via DOMAIN_CHECK_TIMEOUT env var
   - Default remains 3 seconds
   - Allows users to adjust for slow networks/servers

4. Source Guards (all library files)
   - Added source guard pattern to prevent re-sourcing
   - Added to: reference-db.sh, common-functions.sh, system-detect.sh
   - Prevents variable/function duplication if file is sourced twice

Testing: All syntax checks pass, functionality verified

Developer 16f222fc0e CRITICAL FIXES: Security vulnerabilities in reference-db.sh and common-functions.sh 
SECURITY FIXES:
1. SQL Injection (reference-db.sh:183)
   - Escape database names with backticks in WHERE clause
   - Changed: WHERE table_schema='' → WHERE table_schema=``
   - Prevents malicious database names from breaking SQL queries

2. Password Exposure (reference-db.sh:166)
   - Stop passing password on command line (visible in ps aux)
   - Changed: mysql -uadmin -p${plesk_mysql_pass} → MYSQL_PWD env var
   - Passwords no longer exposed in process listings
   - Added unset MYSQL_PWD at end of function for cleanup

3. Race Condition in Temp Files (common-functions.sh:173)
   - Replace mkdir -p with mktemp -d for secure temp directory creation
   - Changed: mkdir -p "$TEMP_SESSION_DIR" → mktemp -d -t server-toolkit.XXXXXX
   - Prevents race condition attacks on predictable paths

Testing: All changes validated for syntax and behavior

cschantz 0c88a37b1c Fix menu standards: Replace plain dashes with Unicode separators 
Replaced all plain dash separators (---) with Unicode (───) for consistency:

Fixed lib/common-functions.sh (1):
- print_section(): 79 dashes → 79 unicode dashes

Fixed lib/user-manager.sh (4):
- All occurrences: 79 dashes → 79 unicode dashes (replace_all)

Fixed modules/performance/php-optimizer.sh (1):
- Table separator: 104 dashes → 104 unicode dashes

Fixed modules/security/malware-scanner.sh (4):
- All occurrences: 40 dashes → 40 unicode dashes (replace_all)

All 8/8 separator issues resolved. Menus now have consistent Unicode styling.

cschantz 9deca7f346 Add parameter validation to 6 more functions + QA improvements 
PARAMETER VALIDATION FIXES (6 functions):
1. lib/common-functions.sh:219 - format_duration()
2. lib/php-detector.sh:277 - get_fpm_process_count()
3. lib/user-manager.sh:263 - get_plesk_user_domains()
4. modules/performance/hardware-health-check.sh:44 - add_finding()
5. modules/performance/hardware-health-check.sh:55 - command_exists()
6. modules/performance/network-bandwidth-analyzer.sh:45 - add_finding()
7. modules/performance/network-bandwidth-analyzer.sh:56 - command_exists()

All functions now validate required parameters with:
- [ -z "$1" ] && return 1 (single param)
- [ -z "$1" ] || [ -z "$2" ] && return 1 (multiple params)

QA SCRIPT IMPROVEMENTS:
- tools/toolkit-qa-check.sh: Skip $@ / $* passthrough functions
  - Added filter for echo/printf functions using only $@ or $*
  - Example: cecho() { echo -e "$@" }
  - These don't need validation as they passthrough all args

PROGRESS:
- HIGH issues remain at 10 (different ones now)
- Eliminated more false positives
- Next: Fix remaining issues in bot-analyzer.sh

cschantz 13be01802c Fix 3 HIGH issues with parameter validation + QA improvements 
PARAMETER VALIDATION FIXES (3 functions):
1. lib/common-functions.sh:238 - command_exists()
   - Added [ -z "$1" ] && return 1

2. lib/php-detector.sh:284 - get_fpm_memory_usage()
   - Added [ -z "$1" ] && return 1

3. lib/user-manager.sh:271 - get_interworx_user_domains()
   - Added [ -z "$1" ] && return 1

QA SCRIPT IMPROVEMENTS:
- tools/toolkit-qa-check.sh: Filter out AWK/sed field references
  - Problem: $1 in awk '{print $1}' was detected as bash parameter
  - Solution: grep -v 'awk\|sed' before checking for $1-9
  - Impact: Eliminates 7 false positives from functions with no params

FALSE POSITIVES ELIMINATED:
- is_server_stressed() - $1 was from awk command
- calculate_server_memory_capacity() - $2 was from awk command
- calculate_balanced_memory_allocation() - $2 was from awk command
- list_cpanel_users() - no parameters
- list_interworx_users() - no parameters
- list_system_users() - no parameters
- press_enter() - $1 was from neighboring function

IMPACT:
HIGH issues: 10 → 10 (fixed 3, eliminated 7 FPs, but 10 new remain)
Need to improve QA script further to extract exact function bodies

cschantz 111c9ec17e Add color code bug prevention: cecho helper + coding guidelines 
PREVENTION STRATEGY for "echo without -e" bug:

1. NEW HELPER FUNCTION - cecho()
   - Added to lib/common-functions.sh (lines 100-115)
   - Wrapper around echo -e for colored output
   - Clear documentation with examples
   - Usage: cecho "${BOLD}Text${NC}" instead of echo -e

2. COMPREHENSIVE CODING GUIDELINES
   - Created CODING_GUIDELINES.md
   - Documents the echo -e color bug with examples
   - Prevention rules and quick reference table
   - Search command to find potential issues
   - Pre-commit checklist for developers
   - Performance guidelines (subprocess elimination)

3. DOCUMENTATION INCLUDES:
   - Why the bug happens (escape sequences not interpreted)
   - How to identify it (grep pattern)
   - How to fix it (echo -e or cecho)
   - When to use each approach
   - Historical context (commit 7053b3b)

BENEFITS:
- Future developers can reference guidelines
- cecho() provides cleaner, safer API
- Search pattern helps audit existing code
- Reduces recurring "This happens a lot" issues

USER FEEDBACK ADDRESSED:
User: "This happens a lot with you. is there a way for us to avoid this in the future?"
Answer: Yes - cecho() helper + guidelines document + search pattern
