9361 :: Memory leak when embedding nimscript

• dwin (orginal) [2022-08-11T22:32:15+02:00] view original

  Hello, I am using Nimscripter to add scripting capabilities to my program. I am using it customize the behavior of my program as per the requirement of different clients. However, I have noticed that it leaks memory whenever a script is run. Program crashes once a day because system runs out of memory.

  import strformat, os
  import nimscripter
  
  proc a(n: int) =
    let myScript = NimScriptFile(&"""echo "Hello World {n}" """)
    let intr = loadScript(myScript)
  
  proc main() =
    for i in 0 .. int.high:
      a(i)
      sleep(200)
  
  main()
  Run

  This is a simple example. It ends up using a couple of gigs of RAM in 15 mins. Is this a known issue? Am I doing something wrong?

  This is a nimscripter issue, as such should've been posted there, but I'm guessing something is not GC'd with the interpreter which means a dealloc or similar call is required.
