Adding an audit log to your Rails app

If you have any sort of administrative interface on your web site, you can easily imagine an intruder gaining access and mucking about. How do you know the extent of the damage? Adding an audit log to your app is one quick solution. An audit log should record a few things:

• controller entry points with parameter values
• permanent information about the user, like user_id
• transient information about the user, like IP and user_agent

Using the Rails framework, this is as simple as adding a before_action to your admin controllers. Here’s a basic version that I’m using in production.

'''
This script performs efficient concatenation of files stored in S3. Given a
folder, output location, and optional suffix, all files with the given suffix
will be concatenated into one file stored in the output location.

Concatenation is performed within S3 when possible, falling back to local
operations when necessary.

Run `python combineS3Files.py -h` for more info.

Long story short, Celluloid versions 0.17+ have a memory leak.

The Reason behind this is that completed Celluloid threads are never cleaned up.

We have discovered that our Sidekiq process is leaking memory when we have a lot of tasks that were failed because of exceptions. Unfortunately, having a lot of failed tasks is specific for our application — we do have a lot of small queued jobs to work with social network APIs and other external services.

You can reproduce the problem with this: https://gist.github.com/gazay/3aa78e515ab05cb79f76

# Mina Deploy
# ===========
#
# Adapted from Creative deploy stack in Manabalss v4, Mar.2015, updated to support staging on Jun.2015
# On first deploy do: mina setup --verbose
# Then do           : mina deploy[initialize] --trace
#
# Usage examples:
# mina deploy[soft,seed,compile] to=staging # deploy task with all options | a simple `mina deploy` will deploy to production
# mina rake[db:seed] # for multi-argument tasks # mina 'rake[payments:refund[arg1\,arg2]]'
