About

A pubsub implementation that conforms to the PubSubHubbub protocol with extensions for authentication and security. PubSubHubbub, though originally designed for Atom and RSS feeds, can be applied to any type of data to push notifications over HTTP, eliminating inefficient polling for changes.

• Javadoc

Building

The normal build uses Apache Ant and Apache Ivy to resolve dependencies. The following ant tasks are available:

• init-ivy - Download and install ivy, if necessary
• compile - Compiles the source
• dist - Resolves dependencies, compiles the source, and creates a jar in dist/lib. This is the default task.
• full-dist - Resolves dependencies, compiles the source, creates a jar in dist/lib, and copies dependencies to dist/extlib
• clean - Removes all build files and jars.
• javadoc - Generates javadoc.
• cleandoc - Removes generated javadoc.

H2 Quick Start

H2 is an embedded database that can store tables in-memory or on-disk.

• If ivy is not installed with your ant distribution: ant init-ivy
• Build: ant full-dist
• Create an install-specific config: cp config/example.h2.properties config/local.properties
• The default settings use an in-memory database that is destroyed on restart. If you wish to persist subscriptions, use the alternate endpoint.acp.connection.pubsub.connectionString property with a local directory.
• Start the server: bin/start
• Verify that the server is running http://localhost:8086/health
• Run a performance test: bin/test
• View metrics http://localhost:8086/metrics.
• Stop the server: bin/stop

MySQL Quick Start

• If ivy is not installed with your ant distribution: ant init-ivy
• Build: ant full-dist
• Create a pubsub database.
• Create the database tables: mysql -u [your user] -p -h [your host] pubsub < config/mysql_pubsub_hub.sql
• Create an install-specific config: cp config/example.mysql.properties config/local.properties
• Edit config/local.properties to change pubsub.user, pubsub.password and pubsub.connectionString for your database. You may also want to change any usernames/passwords from their defaults at this time.
• Start the server: bin/start
• Verify that the server is running http://localhost:8086/health
• Run a performance test: bin/test
• View metrics http://localhost:8086/metrics.
• Stop the server: bin/stop
