Forgot to deallocate infinite chunk of memory


Forgot to deallocate infinite chunk of memory



In my Ubuntu machine, Codeblocks software I allocated infinite chunk of memory without any deallocation. And after that my machine became slow. After restarting the system everything seems ok. Will be there any problem in future?





You can't allocate an infinite chunk of memory in the first place.

Memory allocated by the usual mechanisms (malloc, calloc, new, mmap, ...) is internal to the process and will be released when the process dies. Shared memory allocations (shmget, semget, ...) can persist after the process dies, but will not survive a reboot. So your system should be back to normal, with no lingering effects from the large allocation.

How to input without newline? (Python)

How to input without newline? (Python) I am trying to create a simple file editor in Python via the console (called PyCons). Here is my current program: def PyCons(f): file = open(f, "r") appe = open(f, "a") print("n=====nPyCons Editor, v1.2nPython 3.6.1n") global i i = 0 for line in file: i += 1 print(" {}| ".format(i) + line, end='') for k in range(10000000000000): print("n {}| ".format(i+1), end='') inp = input("") if inp == "@PyCons.save()": print("n=====") break else: i += 1 appe.write("n" + inp) I used the end method to make sure that the existing code in the file was printed properly in its line format, but the input function does not have an end attribute. So, when I go to enter code in the editor: end input end PyCons("magic.html") ... ===== PyCons Editor, v1.2 Python 3.6.1 1| <p>Hello!...
