AWS Glacier: Delete vault

Follow these steps to remove all archives from an AWS vault. After this is finished, you will be able to delete the vault itself through the browser console.

Step 1 / Retrieve inventory

This will create a job that collects required information about the vault.

$ aws glacier initiate-job --job-parameters '{"Type": "inventory-retrieval"}' --account-id YOUR_ACCOUNT_ID --region YOUR_REGION --vault-name YOUR_VAULT_NAME

Prune Resque Workers

There is an issue related to running Resque on Heroku and Resque's ability to clean it's state information for workers. This is mostly a cosmetic issue however we got to a point where the Resque Dashboard would timeout because it was trying to display hundreds of workers it thought were sitll running.

This is a heavy handed approach to cleaning up. We are finding any worker that was stared longer than a day ago and manually calling the unregister method. Be advised this will throw DirtyExit errors.

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
