Release date: May ??, 2016

Github repository:  https://github.com/openwebwork
Modules:    webwork2   pg   ww_install

Cautions

Warning : There are significant database upgrades since 2.11, as well as potential new modules. There are also changes to the configuration files which will need to be integrated into your existing configurations. The process for upgrading to 2.12 is described below.:

Upgrade Instructions

1) Go to /opt/webwork/webwork2, /opt/webwork/pg and run

git pull origin master

on each directory (assuming that origin is your remote name for the openwebwork repo).

2) Depending on your system there may be new perl modules added for 2.11. Run check_modules.pl and look for missing modules. They may include:

  • Library Statistics - This is a new feature (see below). There are variables which control whether or not global and local problem statistics are shown in the library browser.
# These flags control if statistics on opl problems are shown in the library
# browser.  If you want to include local statistics you will need to
# run webwork2/bin/update-OPL-statistics on a regular basis.  
$problemLibrary{showLibraryLocalStats} = 1;
# This flag controls whether global statistics will be displayed
$problemLibrary{showLibraryGlobalStats} = 1;
  • Problem Re-Randomization - The problem rerandomization feature (see below) has default options which need to be set.
# The default prPeriod value (re-randomization period) to use for the newly created problem.
# It is suggested to use the value of -1, which means that the course-wide setting would be used
# Setting this to -1 defaults to the use of course-wide settings (suggested)
# Setting this to 0 disables periodic randomization regardless of the course-wide setting
# Setting this to a positive value will override the course-wide setting
$problemDefaults{prPeriod} = -1;

# Periodic re-randomization
################################################################################
# switch to enable periodic re-randomization
$pg{options}{enablePeriodicRandomization} = 0;
# course-wide default period for re-randomization, should be an integer
# the value of 0 disables re-randomization
$pg{options}{periodicRandomizationPeriod} = 5;

4) Check localOverrides.conf.dist and look for changes to add to the existing localOverrides.conf. There are a couple of important things here that will negatively affect your system if you don't deal with them.

5) Check site-conf.dist and look for changes to add to the existing site.conf. Things to look for include:

6) Check your apache configuration dist file and look for changes to add to the existing apache configuration file. Things to look for include

7) Restart the webserver. (with apachectl graceful or similar command.)

8) Run the upgrade admin database script. You will ```not``` be able to access your admin course until this is done, and you will need to do that to upgrade the course databases.

upgrade_admin_db.pl

9) Log into the admin course and upgrade the databases for all of your courses. Your server will not be functional until you perform this step.

10) Download the latest version of the OPL using

  • cd /opt/webwork/libraries/webwork-open-problem-library
  • git pull origin
  • OPL-update

Primary Changes

1.

Smaller Changes

Installer

The ww_install installer has been updated to support version 2.12. It has been tested on all of the distributions listed below. The installer has also been refactored to be more modular when it comes to different distributions. If you are interested in modifying the installer to work with your distribution post an issue on the ww_install github. You can read more about it at WeBWorK Installer Guide

Supported Distributions

The following are the distributions and features that are officially still supported. They have all been tested with the webwork installer. You still can use WeBWorK on whatever you like, of course. In particular if you install WeBWorK on a very recent version of Ubuntu or Fedora and have problems let us know.

  • Ubuntu 15.10
  • Ubuntu 16.04 (LTS)
  • Debian 8
  • CentOS 7
  • Fedora 22
  • Fedora 23

What could possibly go wrong?
