Greetings, everyone. This guide is specifically tailored for those developing Client Sources. It covers essential practices for maintaining a healthy codebase, including: Identifying Memory Leaks Effective use of Valgrind RAM optimization strategies Proper implementation of Modern C++ 🧠 What is a Memory Leak? A memory leak occurs when a program allocates memory (via malloc or new) but fails to release it back to the system once it is no longer needed. 🔴 Symptoms include: A continuous increase in RAM consumption. Gradual FPS drops over time. Crashes after extended play sessions. General stability issues. ⚠️ Important Note on Valgrind Valgrind runs natively on Linux and is not directly supported on Windows. ✔ Alternatives for Windows users: WSL (Windows Subsystem for Linux) Virtual Machines (Running Ubuntu or similar) Dr. Memory 🛠️ Installing Valgrind Run the following commands in your terminal: Bash sudo apt update sudo apt install valgrind 🚀 Running Valgrind To analyze your client, compile with debug symbols and run: Bash g++ -g client.cpp -o client valgrind --leak-check=full --show-leak-kinds=all ./client For a deep-dive analysis: Bash valgrind --tool=memcheck --track-origins=yes --leak-check=full ./client 📊 Interpreting the Output When checking your logs, look for these specific terms: definitely lost: A confirmed memory leak. indirectly lost: A leak stemming from a pointer within a leaked structure. possibly lost: Potential leak (pointer points to the middle of a block). still reachable: Memory not freed, but the program still has a pointer to it (lower priority). 🧨 Common Errors vs. Correct Approaches 🔹 1. Raw Pointer Usage (NOT RECOMMENDED) ❌ Outdated approach: C++ std::vector<int*> list; list.push_back(new int(5)); // Manual cleanup required for(auto ptr : list) delete ptr; ✔ Modern C++ Solution: C++ #include <vector> #include <memory> std::vector<std::unique_ptr<int>> list; list.push_back(std::make_unique<int>(5)); // Memory is freed automatically 🔹 2. Using DELETE ❌ Redundant check: C++ if(ptr != nullptr) delete ptr; ✔ Correct usage: C++ delete ptr; ptr = nullptr; 🔹 3. C-Style Allocation (malloc / free) C++ char* buffer = (char*)malloc(256); // Always ensure there is a matching free free(buffer); 🔹 4. String Optimization ❌ Inefficient concatenation: C++ std::string s = "test"; s = s + "abc"; ✔ Optimized approach: C++ std::string s = "test"; s.reserve(100); // Pre-allocate memory to prevent multiple reallocations s += "abc"; 🧠 RAM Optimization Techniques Utilize Smart Pointers: Prefer unique_ptr or shared_ptr to manage lifetimes automatically. Implement Object Pools: Avoid constant allocations and deallocations; reuse existing objects instead. Asset Management: Use lazy loading and cache systems to clear unused assets from memory. Avoid Unnecessary Allocations: C++ for(int i = 0; i < 10000; i++) new Object(); // ❌ Avoid this pattern inside loops ⚠️ Potential Valgrind Issues Slow Execution: It is normal for Valgrind to slow down the application by 10-20x. Invalid Read / Write: Occurs when accessing out-of-bounds memory. C++ int arr[5]; arr[10] = 1; // ❌ Out of bounds Segmentation Fault: Caused by null pointer dereferencing or accessing memory after it has been freed. 🔍 Debugging Recommendations Always compile with -g for detailed line-number reporting. Adopt Modern C++ as a standard. Make leak checking a routine part of your development cycle. 🧩 Bonus: SAFE_DELETE Macro C++ #ifdef DEBUG #define SAFE_DELETE(p) { if(p) { delete (p); (p)=nullptr; } } #else #define SAFE_DELETE(p) delete (p) #endif 🔚 Results By following these steps, you will achieve: ✅ Significantly lower RAM usage. ✅ A more stable game client. ✅ Fewer crashes and improved performance. ✏️ EDIT: Technical details regarding Modern C++ have been updated based on community feedback. Thanks to everyone who contributed! If you found this helpful, let me know! In the future, I can cover: Advanced Client FPS Boost + Render Optimization Deep-Level MMO Script Memory Management

I won't beat around the bush—those who have dealt with server crashes or unexplained lag already know exactly how frustrating this issue is. Please remember to adjust the values and configurations provided in this guide to fit your specific environment. Today, we are diving into a topic that hasn't been covered in depth on this forum but is absolutely vital for any large-scale project (1000+ players): Detecting Memory Leaks. Many server owners complain about sudden lag or notice that their RAM fills up completely after three days, forcing a reboot. The primary culprit is usually poorly implemented new and malloc commands in custom systems that were never properly closed or deleted. This guide will show you how to pinpoint these leaks with surgical precision. 🛠 Step 1: Installing Valgrind To begin, you need to install Valgrind on your server via Putty. Use the command corresponding to your operating system: For FreeBSD: Bash pkg install -y valgrind For Ubuntu or Debian: Bash sudo apt-get update && sudo apt-get install valgrind -y 🚀 Step 2: Launching Game Core Analysis Typically, you start your game using ./sh start.sh or ./game. To catch leaks, we must run the game through Valgrind instead. Navigate to your game directory and execute the following command: Bash valgrind --leak-check=full --show-leak-kinds=all --log-file=leak_report.txt ./game 📊 Step 3: Pointer Comparison Table (Best Practices) To prevent leaks from happening in the first place, we should move away from old habits and adopt modern C++ methods: Feature Classic Pointer (Raw) Modern Pointer (Smart) Syntax CHARACTER* ch = new CHARACTER; auto ch = std::make_unique<CHARACTER>(); Deletion Requires manual delete ch;. Automatically deleted. Leak Risk ❌ Extremely High ✅ Zero 🔍 Step 4: Analyzing the Report (leak_report.txt) After running the command for a while (log into the game, walk around, and trigger some systems), download the leak_report.txt file created in your directory via WinSCP. If you see an error like the one below, you've successfully found a leak: Plaintext 40 bytes in 1 blocks are definitely lost at 0x4C29F73: malloc (vgpreload_memcheck.so) by 0x401087: CreateNewItem (item_manager.cpp:150) What does this report tell us? "definitely lost": This confirms a definitive memory leak exists. "item_manager.cpp:150": Memory was allocated on line 150 but was never freed or deleted. ✅ Conclusion and Recommendations Every time you add a new system, make sure to run a 10–15 minute test with Valgrind. If you are still using the old-school new method, ensure you handle the delete operation within the destructor. If you want your server to remain stable for weeks without needing a reboot, this optimization is mandatory.
