Raw

    • Renamed COMMON_AWS_SYNC_BUCKET to COMMON_OBJECT_STORE_LOG_SYNC_BUCKET
    • Renamed COMMON_AWS_S3_SYNC_SCRIPT to COMMON_OBJECT_STORE_LOG_SYNC_SCRIPT
    • Added COMMON_OBJECT_STORE_LOG_SYNC_PREFIX. Default: logs/tracking/

  • Role: aws

    • Removed AWS_S3_LOGS
    • Added vhost role as dependency

  • Role: edxapp

    • Added EDXAPP_SWIFT_USERNAME
    • Added EDXAPP_SWIFT_KEY
    • Added EDXAPP_SWIFT_TENANT_ID
    • Added EDXAPP_SWIFT_TENANT_NAME
    • Added EDXAPP_SWIFT_AUTH_URL
    • Added EDXAPP_SWIFT_AUTH_VERSION
    • Added EDXAPP_SWIFT_REGION_NAME
    • Added EDXAPP_SWIFT_USE_TEMP_URLS
    • Added EDXAPP_SWIFT_TEMP_URL_KEY
    • Added EDXAPP_SWIFT_TEMP_URL_DURATION
    • Added EDXAPP_SETTINGS to allow using a settings file other than aws.py. Default: aws
    • Renamed ENABLE_S3_GRADE_DOWNLOADS to ENABLE_GRADE_DOWNLOADS
    • Replaced EDXAPP_GRADE_STORAGE_TYPE, EDXAPP_GRADE_BUCKET and EDXAPP_GRADE_ROOT_PATH with EDXAPP_GRADE_STORAGE_CLASS and EDXAPP_GRADE_STORAGE_KWARGS

  • Role: openstack

    • Added role

  • Role: vhost

    • Added as dependency for aws and openstack roles. Handles common functionality for setting up VM hosts

  • Role: xqueue

    • Added XQUEUE_SETTINGS to specify which settings file to use. Default: aws_settings
    • Renamed XQUEUE_S3_BUCKET to XQUEUE_UPLOAD_BUCKET
    • Renamed XQUEUE_S3_PATH_PREFIX to XQUEUE_UPLOAD_PATH_PREFIX

  • Role: discovery

    • Course Discovery JWT configuration now takes a list of issuers instead of a single issuer. This change is not backward compatible with older versions of course discovery.

  • Role: hadoop_common

    • Enable log retention by default to assist with debugging. Now YARN will retain stdout and stderr logs produced by map reduce tasks for 24 hours. They can be retrieved by running "yarn logs -applicationId YOUR_APPLICATION_ID".

  • Role: rabbitmq

    • Removed the RABBITMQ_CLUSTERED var and related tooling. The goal of the var was to be able to setup a cluster in the aws environment without having to know all the IPs of the cluster before hand. It relied on the hostvars ansible varible to work correctly which it no longer does in 1.9. This may get fixed in the future but for now, the "magic" setup doesn't work.
    • Changed rabbitmq_clustered_hosts to RABBITMQ_CLUSTERED_HOSTS.

  • Role: edxapp

    • Removed SUBDOMAIN_BRANDING and SUBDOMAIN_COURSE_LISTINGS variables

  • Role: ora

    • Remove the ora1 role as support for it was deprecated in Cypress.
    • Removed dependencies on ora throughout the playbooks / vagrantfiles.

  • Role: edxapp

    • Removed XmlModuleStore from the default list of modulestores for the LMS.
    • EDXAPP_XML_MAPPINGS variable no longer exists by default and is not used by the edxapp role.

  • Role: ecommerce

    • Removed ECOMMERCE_ORDER_NUMBER_PREFIX variable

  • Role: edxapp

    • All of the following changes are BACKWARDS-INCOMPATABLE:
      • Renamed two top level variables SEGMENT_IO_LMS_KEY and SEGMENT_IO_KEY to SEGMENT_KEY in {lms|cms].auth.json.
      • Renamed two top level variables in roles/edxapp/defaults/main.yml. EDXAPP_SEGMENT_IO_LMS_KEY and EDXAPP_SEGMENT_IO_KEY are now EDXAPP_LMS_SEGMENT_KEY and EDXAPP_CMS_SEGMENT_KEY respectively
      • REMOVED two top level variables SEGMENT_IO_LMS and SEGMENT_IO from {lms|cms].auth.json. We will use the existence of the SEGMENT_KEY to to serve the same function that these boolean variables served.
      • REMOVED two top level variables EDXAPP_SEGMENT_IO_LMS and EDXAPP_SEGMENT_IO from roles/edxapp/defaults/main.yml.

  • Updated ansible fork to be based on ansible 1.9.3rc1 instead of 1.9.1

  • Role: edxapp

    • Removed deprecated variables EDXAPP_PLATFORM_TWITTER_URL, EDXAPP_PLATFORM_MEETUP_URL, EDXAPP_PLATFORM_LINKEDIN_URL, and EDXAPP_PLATFORM_GOOGLE_PLUS_URL in favor of EDXAPP_SOCIAL_MEDIA_FOOTER_URLS. These variables haven't been used in edx-platform since March 17, 2015 (when https://github.com/edx/edx-platform/pull/7383 was merged). This change is backwards incompatible with versions of edx-platform from before March 17, 2015.
    • Added EDXAPP_MOBILE_STORE_URLS and EDXAPP_FOOTER_ORGANIZATION_IMAGE variables, used in https://github.com/edx/edx-platform/pull/8175 (v3 version of the edx.org footer).

  • Updated ansible fork with small bug fix.

  • Role: edxapp

    • Removed post.txt from the list of files that will have its github urls replaced with git mirror urls.

  • Role: edxapp

    • The edxapp role no longer uses checksums to bypass pip installs.
      • pip install will always run for all known requirements files.

  • Role: edx-ansible

    • /edx/bin/update no longer runs the ansible command with --tags deploy

  • Role: edxapp

    • Added newrelic monitoring capabilities to edxapp workers. Note that this is a BACKWARDS-INCOMPATABLE CHANGE, as it introduces a new key, monitor, to each item in EDXAPP_CELERY_WORKERS in defaults/main.yml, and plays including this role will fail if that key is not set.

  • Role: edxapp

    • Enabled combined login registration feature by default

  • Role: analytics_api, xqwatcher, insights, minos, edx_notes_api

    • Expanded edx_service role to do git checkout and ec2 tagging

    • Refactored roles that depend on edx_service to use the new interface: minos, analytics_api, insights, and xqwatcher

    • Refactored name from analytics-api to analytics_api

    • Changed location of minos' config file from /edx/etc/minos/minos.yml to /edx/etc/minos.yml

    • Added new edx_notes_api role for forthcoming notes api

    • This is a BACKWARDS INCOMPATABLE change and will require additional migrations when upgrading an existing server. While we recommend building from scratch, running the following command might work:

      rm -rf /edx/app/analytics-api /edx/app/ /edx/app/nginx/sites-available/analytics-api.j2 /edx/app/supervisor/conf.d.available/analytics_api.conf
rm -rf /edx/etc/minos

  • Role: notifier

    • Refactored NOTIFIER_HOME and NOTIFIER_USER to notifier_app_dir and notifier_user to match other roles. This shouldn't change anything since users should've only been overriding COMMON_HOME.

  • Role: gitreload

    • New role added for running gitreload that can be used for importing courses via github/gitlab Web hooks, or more generally updating any git repository that is already checked out on disk via a hook.

  • Role: analytics-api, edxapp, ora, xqueue, xserver

    • Switched gunicorn from using an entirely command argument based configuration to usign python configuration files. Variables for extra configuration in the configuration file template, and command line argument overrides are available.

  • Role: analytics-api, insights

    • Using Django 1.7 migrate command.

  • Role: edxapp

    • A new var was added to make it easy ot invalidate the default memcache store to make it easier to invalidate sessions. Updating the edxapp env.json files will result in all users getting logged out. This is a one time penalty as long as the value of EDXAPP_DEFAULT_CACHE_VERSION is not explicitly changed.

  • Role: nginx

    • New html templates for server errors added. Defaults for a ratelimiting static page and server error static page. CMS/LMS are set to use them by default, wording can be changed in the Nginx default vars.

  • Role: edxapp

    • We now have an all caps variable override for celery workers

  • Role: common

    • We now remove the default syslog.d conf file (50-default.conf) this will break people who have hand edited that file.

  • Role: edxapp

    • Updated the module store settings to match the new settings format.

  • Update, possible breaking change: the edxapp role vars edxapp_lms_env and edxapp_cms_env have been changed to EDXAPP_LMS_ENV and EDXAPP_CMS_ENV to indicate, via our convention, that overridding them is expected. The default values remain the same.

  • Role: analytics-api

    • Added a new role for the analytics-api Django app. Currently a private repo

  • Logrotation now happens hourly by default for all logs.

  • Role: xqwatcher, xqueue, nginx, edxapp, common

    • Moving nginx basic authorization flag and credentials to the common role
    • Basic auth will be turned on by default

  • Role: Edxapp

    • Turn on code sandboxing by default and allow the jailed code to be able to write files to the tmp directory created for it by codejail.

  • Role: Edxapp

  • Update CMS_HOSTNAME default to allow any hostname that starts with studio along with prod-studio or stage-studio.

  • Start a change log to keep track of backwards incompatible changes and deprecations.

  • Role: Mongo

    • Fixed case of variable used in if block that breaks cluster configuration by changing mongo_clustered to MONGO_CLUSTERED.

  • Role: Edxapp

    • Added EDXAPP_LMS_AUTH_EXTRA and EDXAPP_CMS_AUTH_EXTRA for passing unique AUTH_EXTRA configurations to the LMS and CMS. Both variables default to EDXAPP_AUTH_EXTRA for backward compatibility

  • Role: ecommerce

    • Renamed ECOMMERCE_COMPREHENSIVE_THEME_DIR to ECOMMERCE_COMPREHENSIVE_THEME_DIRS, ECOMMERCE_COMPREHENSIVE_THEME_DIRS is now a list of directories. Change is backward incompatible.
    • Renamed COMPREHENSIVE_THEME_DIR to COMPREHENSIVE_THEME_DIRS, COMPREHENSIVE_THEME_DIRS is now a list of directories. Change is backward incompatible.

  • Role: Edxapp

    • EDXAPP_COMPREHENSIVE_THEME_DIR is deprecated and is maintained for backward compatibility, EDXAPP_COMPREHENSIVE_THEME_DIRS should be used instead which is a list of directories. EDXAPP_COMPREHENSIVE_THEME_DIR if present will have priority over EDXAPP_COMPREHENSIVE_THEME_DIRS
    • COMPREHENSIVE_THEME_DIR is deprecated and is maintained for backward compatibility, COMPREHENSIVE_THEME_DIRS should be used instead which is a list of directories. COMPREHENSIVE_THEME_DIR if present will have priority over COMPREHENSIVE_THEME_DIRS
