How to recover lost Python source code if it's still resident in-memory

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

// Notes:
// 1) You should make full project rebuild during customer build
// 2) Keep error handling simple: just print message to cout and call exit(-1)
// 3) You can customize the number of days in evaluation period:
