Beta Features

This page describes how to code and enable beta features on a server from the perspective of a developer, including how to turn on beta features on your Dreamhack. For instructions on doing beta work as a user, see Beta Testing.

Putting a Feature into Beta

Features in active beta are listed on Dreamwidth Beta. To add a feature to that list, you will need to create a new module and configure the server to enable the feature beta.

Here is the bare minimum to get a module to work, to be placed in

# DW::BetaFeatures::featurename - Allow users to beta test featurename

package DW::BetaFeatures::featurename;
use strict;
use base "LJ::BetaFeatures::default";

Refer to the base implementation at dw-free/cgi-bin/LJ/BetaFeatures/ for methods that you can override.

Configuring your Server to List the New Feature

To turn on beta features on your Dreamhack, you'll also need to enable them in your configuration. The config lines for the DW beta features are commented out in etc/ To enable them, copy those lines to ext/local/etc/ (and uncomment if needed). They will look something like this:

       "updatepage" => {
           start_time  => 0,
           end_time    => "Inf",

If you're writing a new feature, you will need to add a line for it here, e.g. by replacing "updatepage" with "featurename".

The actual names of the existing beta features can be found by going to this page or asking about them at [info]dw_dev_training.

Conditionally Enabling Features for Beta Testers

To determine whether a user has enabled a certain feature, use this in an if-statement:

 LJ::BetaFeatures->user_in_beta( $u => "featurename" );
