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

cd /Library/Preferences
sudo rm com.sophos.sav.plist

cd /Library/Application\ Support/Sophos/cloud/Installer.app/Contents/MacOS/tools/
sudo ./InstallationDeployer —force_remove

The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

	class TenantAwareManager(Manager):
	def get_queryset(self):
	tenant_id = current_tenant_id()

	# If the manager was built from a queryset using
	# SomeQuerySet.as_manager() or SomeManager.from_queryset(),
	# we want to use that queryset instead of TenantAwareQuerySet.
	if self._queryset_class != QuerySet:
	return super().get_queryset().filter(tenant__id=tenant_id)
