From cb5352db22346249f4b1efc728cd4d9ebb3d53fb Mon Sep 17 00:00:00 2001 From: Developer Date: Mon, 20 Apr 2026 17:43:09 -0400 Subject: [PATCH] fix: Critical bugs in three-constraint intelligent model MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit FIXED BUGS: BUG #1: MySQL Memory Field Extraction (CRITICAL) - Was using cut -d'|' -f3 on a 2-field output - detect_mysql_memory_usage returns: memory|status - Fixed to use cut -d'|' -f1 (corrects both functions) - Impact: MySQL memory was calculated as 0, leading to inflated capacity - Fix severity: CRITICAL - affects all server capacity calculations BUG #2: Domain Traffic Percentage Analysis (CRITICAL) - Previous implementation had broken loop logic - Was counting files multiple times, producing wrong percentages - Completely rewrote to use simplified approach: - Best-effort search for domain-specific access logs - Falls back to equal distribution if logs not found - Supports cPanel, Plesk, and InterWorx log locations - Impact: Traffic percentages were wildly inaccurate - Fix severity: CRITICAL - affects fair share allocation BUG #3: Hardcoded Log Paths (MODERATE) - Only worked on cPanel, failed on other control panels - Now searches multiple standard log locations - Falls back to equal distribution for portability - Impact: Script would fail or give wrong results on Plesk/InterWorx - Fix severity: MODERATE - affects multi-panel support TESTING COMPLETED: - ✅ Syntax validation: All files pass bash -n check - ✅ Logic verification: 8GB server test case works correctly - Expected capacity: 245 max_children - Test result: 245 max_children ✓ - ✅ Fair share allocation math verified - ✅ Three-constraint MIN logic verified - ✅ Function calls verified in batch analyzer and optimizer All three scripts now ready for field testing. --- lib/php-calculator-improved.sh | 100 ++++++++++++++++++--------------- 1 file changed, 55 insertions(+), 45 deletions(-) diff --git a/lib/php-calculator-improved.sh b/lib/php-calculator-improved.sh index 8dcb4f6..71a3266 100644 --- a/lib/php-calculator-improved.sh +++ b/lib/php-calculator-improved.sh @@ -110,7 +110,8 @@ calculate_max_children_memory_based() { local mysql_info mysql_info=$(detect_mysql_memory_usage 2>/dev/null) if [ $?
