From c6300b8abef57b5243b68fb0e83f7354dda038d2 Mon Sep 17 00:00:00 2001 From: cschantz Date: Fri, 21 Nov 2025 15:17:04 -0500 Subject: [PATCH] Fix critical integer expression and regex errors across multiple modules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PROBLEM: Multiple tools were experiencing runtime errors: 1. MySQL analyzer: integer expression expected 2. System health check: 5 integer comparison failures 3. Bot analyzer: InterWorx log detection failing 4. Reference DB: grep regex errors (unmatched brackets) ROOT CAUSES IDENTIFIED: 1. **stdout Pollution in Command Substitution** - Functions using print_info/print_success in command substitution - Output bleeding into variables causing "0\n0" values - Integer comparisons failing on malformed values 2. **Missing Variable Sanitization** - grep -c output containing newlines/whitespace - Variables used in [ -gt ] comparisons without validation - No fallback for empty/malformed values 3. **Unmatched Bracket Expressions** - Regex pattern [^/'\"']+ had quote outside bracket - Should be [^/'"]+ (match not slash/quote) - Caused "grep: Unmatched [ or [^" errors 4. **InterWorx Log Path Issues** - Time-filtered searches returning zero results - No diagnostic output for troubleshooting - No fallback to analyze all logs FIXES APPLIED: **MySQL Analyzer (lib/mysql-analyzer.sh):** - Redirect print_info/print_success to stderr (>&2) in: * capture_live_queries() * parse_slow_query_log() * analyze_queries_for_problems() - Prevents stdout pollution in command substitution - Functions now return only filename via echo **MySQL Query Analyzer (modules/performance/mysql-query-analyzer.sh):** - Sanitize critical_count variable: * Strip newlines with tr -d '\n\r' * Extract only digits with grep -o '[0-9]*' * Set fallback default ${var:-0} - Add 2>/dev/null to integer comparison **System Health Check (modules/diagnostics/system-health-check.sh):** Fixed 5 integer comparison errors: - Line 501-503: max_workers_hits sanitization - Line 511: max_workers_hits comparison - Line 522: segfaults sanitization and comparison - Line 820: tcp_retrans/tcp_out sanitization - Line 1684: Duplicate tcp_retrans/tcp_out sanitization All variables now cleaned and have safe defaults **Bot Analyzer (modules/security/bot-analyzer.sh):** Enhanced InterWorx log detection (line 1811-1843): - Check for logs WITHOUT time filter first - If zero: Show diagnostic info (directory structure, available logs) - If some exist: Offer to analyze all logs (not just time-filtered) - Better error messages with actionable information **Reference Database (lib/reference-db.sh):** - Line 436: Fixed regex [^/'\"']+ → [^/'\"]+ - Removed mismatched quote outside bracket expression **User Manager (lib/user-manager.sh):** - Line 647: Fixed regex [^/'\"']+ → [^/'\"]+ - Added 2>/dev/null and || true for error suppression TESTING: ✅ All 6 modified files pass bash -n syntax check ✅ Integer expressions now properly sanitized ✅ Regex patterns valid (no unmatched brackets) ✅ InterWorx detection has better diagnostics IMPACT: - MySQL analyzer will work without stdout pollution errors - System health check won't crash on empty/malformed variables - Bot analyzer provides helpful feedback for InterWorx servers - Reference DB builds without grep regex errors - All integer comparisons safe with proper defaults These were blocking errors preventing normal tool operation.
