3.12 Smart Garbage Collector
Avoid memory problems :-
• Invalid Memory Access
• Memory leaks
• Uninitialized Memory Access
• Dangling pointer
Rules :-
• Global variables always stay in the memory, until you delete these variables using the assignment statement.
• Local variables always deleted after the end of the function.
• The programmer have full control on when to delete the variable from the memory using the Assignment state-
ment.
Example:
aList = [1,2,3,4,5]
aList = "nice"
After the second line directly, The list [1,2,3,4,5] will be deleted from the memory and we will have a string “nice”
• The programmer can call the function callgc() to force running the garbage collector.
• If we have a reference to a variable (when we pass objects and lists to functions), then deleting variables will be
based on reference counting, if no references everything will be deleted, but if we have a reference, the data will
stay in memory.

- 3. Ring Documentation, Release 1.10 3.13 No Global Interpreter (VM) Lock - No GIL When we use threads in Ring applications, We don’t have global interpreter (VM) lock (No GIL) So threads can work in parallel and execute Ring instructions at the same time This is better for threads and concurrency (More Faster!) 3.14 Fast Enough For Many Applications Ring is designed to be a simple, small and flexible language in the first place, but also it is fast enough for many applications. Ring can do each of the next tasks in around 1 second using normal computers in the market during the last 5 years 1. Compiling 100,000 lines of code 2. Executing empty loop that count from 1 to 10,000,000 3. Executing 1000 search operation using linear search in a list contains 100,000 items, trying to find the last item (The worst case) 4. Creating list contains 1,000,000 items then summing all of the list items 5. Adding 20,000 items to the ListWidget in GUI applications 6. Adding 5,000 nodes to the TreeWidget in GUI applications 7. Printing 10,000 messages to the terminal in Console applications Also when we need more speed we can use C/C++ extensions! 3.13. No Global Interpreter (VM) Lock - No GIL 40
