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
#!/usr/bin/sudo sh

## Well, good, as long as its not intended to discourage *me* from doing this!

This code implements Johnson's algorithm to solve the "all pairs shortest path" problem, ie. given an input graph with general edge weights (can be negative) with no negative cycles, find the shortest (u, w) path for all pairs of vertices (u, w). If the input graph has any negative cycles, the program will report this and halt (since there is no…
