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

REALLY quick and dirty static file dev server

Usage

node dirtyserve.js

The point your browser to

http://localhost:3000/myfile.xxx

and the server will try to serve that file from the local server.

sudo curl -o /usr/local/bin/imgcat -O https://raw.githubusercontent.com/gnachman/iTerm2/master/tests/imgcat && sudo chmod +x /usr/local/bin/imgcat
# If you have a better way to fix the permissions, comment below!

sudo cp /etc/postgresql/9.3/main/postgresql.conf ~
sudo cp /etc/postgresql/9.3/main/pg_hba.conf ~
# Package repo (for apt-get)
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main" >> /etc/apt/sources.list.d/postgresql.list'
# Also probably optional but I like to update sources and upgrade
sudo apt-get update
