描述

Feature or enhancement

Proposal:

This idea may be similar to #60585

In the production environment, the memory leak is a common issue for all the developers. For now, we may have two kinds of way to debug it.

  1. Intrusive way, we need to modify our code, inject some code to monitor the object malloc, and publish/deploy it again. It will use a lot of time in non-python-code process.
  2. Process attach way, we may use the tools like py-spy or other ptrace based way to attach to the process, and dump/analyze the all memory. It's useful but will be limited in the container. For most circumstance, we limit the privilege of the container which is means that the ptrace based way will be unuseable because of the security issue.

I think maybe we can introduce a new -x option to dump heap and current stack automaticlly when MemoryError has been raised just like the developer did in JVM
