[NEW EXAMPLE] Puppet - Connection Pool

[ainzzorl]

General

• Project name: Puppet
• Example name: HTTP Connection Pool
• Project home page: https://github.com/puppetlabs/puppet
• Programming language(s): Ruby

Description

Puppet, an automated administrative engine for your Linux, Unix, and Windows systems, performs administrative tasks (such as adding users, installing packages, and updating server configurations) based on a centralized specification.

Puppet client implements a connection pool to reuse server connections.

Connections are borrowed from the pool, yielded to the caller, and released back into the pool. If a connection is expired, it will be closed either when a connection to that site is requested, or when the pool is closed. The pool can store multiple connections to the same site, and will be reused in MRU order.

• Generic, reusable.
• Short and simple.
• Idiomatic Ruby.

Again, it's not the most interesting part of Puppet by a long shot, but it's understandable in isolation.
