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

Phabricator Ubuntu Installation Guide

This is a supplement to the official Phabricator Installation Guide, because their guide will leave you with all kinds of permission and config errors and ~15,000 setup issues on startup.

Install bonus packages:

# apt-get install mercurial subversion python-pygments sendmail imagemagick

Create necessary users and add phd-user to sudoers:
