.. _Changelog-0.13next:

v0.13next

=========

Released: UNRELEASED

Synnefo-wide

------------

* Create 'snf_django' Python package to hold common code for all Synnefo

  components.

Astakos

-------

* Redesign of the accounting system (quotaholder) and integration into

astakos.

  * Simplified the quotaholder model; removed tables Entity and Policy; now

    table Holding contains limit and usage for every holding.

  * Extended table Holding, so that we can keep track of quota for every

    valid combination of holder (e.g. user), resource, and source (e.g. the

    default system or some specific project).

  * Refactored code for issuing and resolving commissions for robustness;

    added a 'force' option to bypass the upper limit check when issuing a

    commission.

  * Simplified syncing to the quotaholder; removed fields from models

    Project and ProjectMembership, previously needed for syncing; removed

    state PROJECT_DEACTIVATED from ProjectMembership.

  * Removed settings ASTAKOS_QUOTAHOLDER_URL, ASTAKOS_QUOTAHOLDER_TOKEN,

    and ASTAKOS_QUOTAHOLDER_POOLSIZE.

* Service and resource specification and handling:

  * Specified a format for defining resources a service exposes. Migrated

    internal resource name by prefixing it with service name (e.g. 'vm'

    becomes 'cyclades.vm'); renamed registered service 'pithos+' to

    'pithos'.

  * Specified a procedure to register a service's resources in astakos and

    set their respective default base quota limit. Removed resource

    definitions from settings.

  * Moved service and resource presentation data out of the respective db

    models into a separate file of UI constants.

* Converted the limit on pending applications from a setting to a quotable

  resource. Converted the related user setting to a user-specific base quota

  limit. Deprecated model UserSetting; removed setting

  ASTAKOS_PENDING_APPLICATION_LIMIT.

* Changes in locking strategy:

  * Lock only project's chain for all project operations; lock user before

    syncing to quotaholder.

  * When locking multiple rows (e.g. users or holdings) include an ORDER BY

    clause in the query to impose ordering on locking.

* API-related changes:

 * Implemented API calls for quota, resources, and commissions.

 * Moved all API calls under '/astakos/api'. Kept also previous locations

   for backwards compatibility.

* Changes in views:

  * Replaced custom transaction context with a simple decorator for managing

    transactions and a context 'ExceptionHandler', which logs and suppresses

    exceptions

* Management commands:

  * Renamed command astakos-quota to quota; user-update to user-modify.

  * Removed user-set-initial-quota; integrated its functionality in

    user-modify and quota.

  * Added quota and project-related information in user-show command; added

    membership information in project-show.

Cyclades

--------

* Make 'type' attribute required for network create API request.

* Networks not created to all Ganeti backends upon creation, they are instead

  created to a backend only when a VM connects to the network.

* Add 'ASTAKOS_POOLSIZE' setting which tunes the size of the http connection

  pool to astakos.

* Remove 'CYCLADES_USER_CATALOG_URL' and 'CYCLADES_USER_FEEDBACK_URL' settings

* Remove CYCLADES_USE_QUOTAHOLDER, CYCLADES_QUOTAHOLDER_TOKEN,

  CYCLADES_QUOTAHOLDER_URL, CYCLADES_QUOTAHOLDER_POOLSIZE settings

* Rename 'cyclades-usage-verify' management command to

  'reconcile-resources-cyclades'. Also, remove 'cyclades-usage-reset' command,

  which is equivalent to 'reconcile-resources-cyclades --fix'.

* Rename 'cyclades-reconcile-commissions' management command to

  'reconcile-commissions-cyclades'.

* Remove obsolete 'MAX_VMS_PER_USER', 'MAX_NETWORKS_PER_USER',

  "VMS_USER_QUOTA" and "NETWORKS_USER_QUOTA" settings, since their usage

  is covered by Quotaholder.

Pithos

------

* Remove PITHOS_AUTHENTICATION_USERS setting, which was used to override

  astakos users.

* Remove 'PITHOS_USER_CATALOG_URL', 'PITHOS_USER_FEEDBACK_URL' and

  'PITHOS_USER_LOGIN_URL' settings.

* Remove PITHOS_USE_QUOTAHOLDER, PITHOS_QUOTAHOLDER_URL,

  PITHOS_QUOTAHOLDER_TOKEN and PITHOS_ASTAKOSCLIENT_POOLSIZE
