Changes you will need to make: * In your environment.rb, you will need to update references to a few files per environment.rb.tmpl * In your environment.rb, you will need to specify the local time zone of the computer that is running your Tracks install. Other notes on my changes: * Modified our code to take advantage of Rails 2.1's slick time zone support. * Upgraded will_paginate for compatibility * Hacked the Selenium on Rails plugin, which has not been updated in some time and does not support Rails 2.1 * Verified that all tests pass on my machine, including Selenium tests -- I'd like confirmation from others, too.

# This file includes an experimental gateway CGI implementation. It will work
|
|
# only on platforms which support both fork and sockets.
|
|
#
|
|
# To enable it edit public/.htaccess and replace dispatch.cgi with gateway.cgi.
|
|
#
|
|
# Next, create the directory log/drb_gateway and grant the apache user rw access
|
|
# to said directory.
|
|
#
|
|
# On the next request to your server, the gateway tracker should start up, along
|
|
# with a few listener processes. This setup should provide you with much better
|
|
# speeds than dispatch.cgi.
|
|
#
|
|
# Keep in mind that the first request made to the server will be slow, as the
|
|
# tracker and listeners will have to load. Also, the tracker and listeners will
|
|
# shutdown after a period if inactivity. You can set this value below -- the
|
|
# default is 90 seconds.
