How to share mmap between python and node processes

QUESTION

How to share mmap between python and node processes

Asked 2020-Oct-21 at 18:19

I'm trying to share memory between a python process and a nodejs process started from the python process using an anonymous mmap. Essentially, the python process begins, initializes the mmap and starts a subprocess using either call or Popen to launch a child that runs some node code. This nodejs code uses mmap to try to access the same area in memory. However I get two different mappings and no data is shared between them. Why is this?

...

ANSWER

Answered 2020-Oct-20 at 21:26

Fortunately this doesn't work: imagine how confusing if all of the system's MAP_ANONYMOUS mappings were against the same area and kept overwriting each other.

Instead, use shm_open to create a new handle you can mmap in both processes. This is a portable wrapper around the equally valid but less portable strategy of creating and mmap'ing a file in /dev/shm/.
