HTTP Adapters for PayPal SDK

This gem extends PayPal SDK and allows you to set specific http library.

Currently it supports two adapters:

• :net_http - Net::HTTP (default, blocking I/O)
• :em_http - EM::Http (non-blocking I/0)

Add this line to your application's Gemfile:

gem 'paypal-sdk-http-adapters'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paypal-sdk-http-adapters

PayPal::SDK.http_adapter_name = :net_http

This is default adapter that actually is very simple wrapper for standard Net::HTTP.

PayPal::SDK.http_adapter_name = :em_http

This is adapter for EM::Http library.

When EventMachine is already running we assume that you are responsible for Fiber allocation. You can add Rack::FiberPool to your application middleware and it automatically provides a Fiber for each incoming HTTP request. It creates pool of Fibers and re-use fiber for each incoming HTTP request. Also you can control the connection pool size.
