^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Since v0.13 most of the Synnefo components have been merged into a single

repository and have aligned versions.

v0.14next

=========

Released: UNRELEASED

Synnefo-wide

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

* Integrate Pithos tests in continuous integration.

* Change astakosclient to accept AUTH_URL instead of BASE_URL

  ASTAKOS_BASE_URL settings has been removed from Pithos and Cyclades

  and has been replaced with ASTAKOS_AUTH_URL. Both Pithos and Cyclades

  proxy the Astakos services under ASTAKOS_PROXY_PREFIX path.

  ASTAKOS_PROXY_PREFIX by default has a value of '_astakos'.

  More specifically, Astakos' identity service is proxied under

  '_astakos/identity', Astakos' account service is under '_astakos/account'

  and Astakos' ui service is under '_astakos/ui'.

* Add 'mail_admins' handler to 'django.request' logger in order to send email

  notifactions to users listed in 'ADMINS' setting about unhandled exceptions

  in the code.

* Extend astakosclient to request and validate OAuth 2.0 access tokens

Astakos

-------

* Changes in project schema:

  * A Project entry is created when submitting an application for a new

    project, rather than on approval. Its state is dependent on the state

    of its `reference' application (current definition). Lock Project rather

    than Chain (the latter is semantically obsolete).

  * Project states "Active - Pending" and "Suspended - Pending" have been

    removed. In management command `project-list', the existence of a pending

    modification is indicated by a non-blank `Pending AppID'.

  * Improve recording of project, application, and membership actions.

* Implement API calls for projects.

* Store the base URL of a component. Deployer should provide it when adding

  a new component. Service endpoints originating from a component are

  expected to match its base URL; otherwise, a warning is issued.

  Re-registration with `snf-component-register' affects both the base and

  the ui URL.

* Changes in resource and quota handling:

  * New resources are registered with unlimited default base quota,

    represented by 2**63-1.

  * Each newly accepted user copies the default value for all resources

    as their own base quota. A base quota is considered 'custom' if its

    value differs from the default.

  * Changing resource's default quota affects the base quota *only* of

    future users.

  * Resource definition got flags 'api_visible' and 'ui_visible',

    replacing flag 'allow_in_projects'. They control whether a user can

    access these resources. The system internally always accounts for

    all resources, and a user can get off quota even for a resource that

    is not visible.

* Remove API call GET /account/v1.0/authenticate in favor of

  POST /identity/v2.0/tokens.

* Export basic statistics about Astakos service from '/admin/stats/detail' API

  endpoint. Access to this endpoint is only allowed to users that belong to

  the Astakos groups that are defined in the

  'ASTAKOS_ADMIN_STATS_PERMITTED_GROUPS' setting. Statistics are also availble

  from 'snf-manage stats-astakos' management command.

* Implement OAuth 2.0 Authorization Code Grant

  Add API calls for authorization code and access token generation

* Add API call for validating OAuth 2.0 access tokens

* Management commands:

  * Introduced new commands:

     * component-show

     * quota-list (replacing quota, supports various filters)

     * quota-verify (replacing quota)

	 * oauth2-client-add (register OAuth 2.0 client)

	 * oauth2-client-list (list registered oauth 2.0 clients)

	 * oauth2-client-remove (remove OAuth 2.0 client)

  * Changed commands:

     * component-add got options --base-url and --ui-url

     * resource-modify --limit became --default-quota

     * user-modify can operate on multiple users with --all and --exclude

     * user-modify --set-base-quota became --base-quota

  * Removed commands:

     * quota

     * resource-import (subsumed by service-import)

     * resource-export-astakos (subsumed by service-export-astakos)

Cyclades

--------

* Major changes to Cyclades networks:

  * Implement 'cyclades_network' service, containing the /networks, /ports,

    /subnets and /floatingips API endpoints under '/network/v2.0'.

	The old /networks API of 'cyclades_compute' (under /compute/v2.0) is

	removed.

  * Implement `snf-manage subnet-{create, list, modify, inspect}' management

    commands for handling of subnets.

  * Implement `snf-manage port-{create, list, remove, inspect}' management

    commands for handling of ports.

  * Add two new settings, 'CYCLADES_FORCED_SERVER_NETWORKS' and

	'CYCLADES_DEFAULT_SERVER_NETWORKS' to control the networks that newly

	created servers will be connected.

* Implement Floating IP addresses, which are IPv4 addresses that can be

  dynamically added and removed to a running server.

  * Add new 'cyclades.floating_ip' resource.

  * Implement 'snf-manage floating-ip-{create,list,remove,attach,detach}'

	management commands to handle floating IPs.

  * Add 'floating_ip_pool' attribute to networks to mark networks that can

    be used as floating IP pools.

* Implement 'resize' server action.

  * Implement the 'resize' server action, to change the flavor of a server.

  Only 'cpu' and 'memory' resizing is supported.

* Compute quotas for CPU and memory of running vms.

  * Change 'cyclades.cpu' and 'cyclades.ram' resources to represent the CPU

    and RAM for running VMs. Total CPU and RAM usage is represented by new

    'cyclades.total_cpu' and 'cyclades.total_ram' resources.

* Refer to Ganeti NICs by their name instead of their index.

  * Make cyclades give a unique name to each Ganeti NIC. NICs are refered by

    their unique name and not by their index inside the VM that are connected

	to.

* Support firewall profile for all NICs of an instance. Change firewall

  settings to be filled with the unique name of the NIC. The affected settings

  are the GANETI_FIREWALL_{ENABLED, DISABLED, PROTECTED}_TAG settings.

* Add accounting for public IP addresses that is accessible via `snf-manage

  ip-list` management command and via the helpdesk app.

* Implement IPv6 only networks.

* Extend servers info API response with 'SNF:fqdn' attribute, and introduce

  CYCLADES_SERVERS_FQDN to set the template for servers FDQN. Remove

  'UI_VM_HOSTNAME_FORMAT' setting.

* Extend servers info API response with 'SNF:port_forwarding' attribute,

  describing port fowarding rules (DNAT) that are applied to vms. The

  description of such rules is done via the new CYCLADES_PORT_FORWARDING

  setting.

* Speed up server reconciliation, by performing parallel reconciliation for

  each backend.

* Change --dhcp option of network management commands from a flag to a boolean

  value, e.g. --dhcp=True

* Remove 'ARCHIPELAGO_BACKENDS' setting used to distinquish between backends

  that hosted only archipelago backends. Instead allocation is based on which

  disk-templates are enabled in each backend.

* Implement 'snf-manage server-remove' management command.

* Move reconciliation of IP pools from 'reconcile-networks' to

  'reconcile-pools'. The IP pool reconciliation does not reconcile the IP

  pools with Ganeti. Instead it checks if the pool is consistent with the

  IPs that are used by instances.

* Do not automatically release externally reserved IPs if they are released

  from a Ganeti backend. Management of externally reserved IPs must be

  performed from Cyclades with 'network-modify' command.

* Export basic statistics about Cyclades Service from '/admin/stats/detail'

  API endpoint. Access to this endpoint is only allowed to users that belong

  to the Astakos groups that are defined in the 'ADMIN_STATS_PERMITTED_GROUPS'

  setting.  Statistics are also availble from 'snf-manage stats-cyclades'

  management command.

* Support enforcing quota through command 'enforce-resources-cyclades'.

* Remove command 'resource-export-cyclades' subsumed by

  'service-export-cyclades'.

* Obsolete PUBLIC_USE_POOL setting, since Cyclades manages IP pool for all

  type of networks.

* Encrypt / decrypt the instance id / hostname in the  stats URL in

  snf-cyclades-app and snf-stats-app, using the 'CYCLADES_STATS_SECRET_KEY'

  and 'STATS_SECRET_KEY' respectively.

* Add support for snf-vncauthproxy-1.5 and the setting

  'CYCLADES_VNCAUTHPROXY_OPTS', which configures the extra options / arguments

  needed by the newer version of snf-vncauthproxy. Support for older versions

  of snf-vncauthproxy has been dropped. See also the upgrade notes for Synnefo

  and snf-vncauthproxy-1.5.

* Remove 'DEFAULT_ROUTING_TABLE' setting. If a link for an IP_LESS_ROUTED

  network is not specified, the link will be uniquely named

  'snf-link-$network_id'.

  (Astakos, Cyclades, Pithos, etc.) that consolidates APIs (services),

  resources, and other standardized properties (e.g. default URL prefixes).

* Standardize URLs for Synnefo Components, impose structure and naming

  conventions to related settings. Make each component deployable under

  a user-configurable <COMPONENT>_BASE_URL. Each API (compute, image, etc.)

  is deployable under a developer-configurable prefix beneath BASE_URL.

* Deprecate CLOUDBAR_ACTIVE_SERVICE setting from all apps. 

* Common synnefo 404/500 templates (located in snf-webproject)

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.

* API-related changes:

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

  * Moved all API calls under '/account/v1.0'.

  * Implemented the keystone API call POST /tokens under '/identity/v2.0'.

* Service and resource specification and handling:

  * Specified a format for defining services along with the API endpoints

    and the resources they expose. 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 Synnefo component, its services and

    their resources in astakos and set the resources' 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.

* Changes in views:

  * Replaced custom transaction context with a simple decorator for managing

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

    exceptions

* Added fine grain user auth provider's policies.

  * Administrator can override default auth provider policies to a specific 

    user or group of users.

  * Optionally a user can be assigned to a list of groups, based on the

    authentication method he choosed to signup.

* Removed explicit handling of SMTP errors on each email delivery. Exceptions 

  are now propagated to base django exception handler.

  support prompts is now defined in ``CONTACT_EMAIL`` setting introduced in 

  snf-common settings.

* Improvements in user activation flow

  * User moderation now takes place after the user has verified his email

    address.

  * User model enriched with additional user state fields

  * Split activation email from moderation process. Administrator is required 

    to moderate user explicitly using the `user-modify --accept` or

    `user-modify --reject` commands.

  * Improved logging throught out user activation procedures.

* Remove deprecated AstakosUser model fields: `provider`,

  `third_party_identifier`

* Allow override of authentication provider messages using the following 

  format in setting names: ``ASTAKOS_<PROVIDER_MODULE>_<MSGID>_MSG``

* Cloudbar automatically tries to identify the active service based on window 

  location.

* Removing authentication provider view is now CSRF protected.

* New `API access` view, containing useful information to users on how to 

  access available Synnefo services API's.

* Remove of ASTAKOS_*_EMAIL_SUBJECT settings. All email subjects are now 

  defined in astakos.im.messages module. Overriding default values can be 

  achieved using custom gettext files or using astakos messages settings::

	#change of greeting email subject

  	ASTAKOS_GREETING_EMAIL_SUBJECT_MESSAGE = 'Welcome to my cloud'

* Remove ``ASTAKOS_ACTIVATION_REDIRECT_URL`` and ``ASTAKOS_LOGIN_SUCCESS_URL`` 

  from astakos .conf file. Settings are dynamically computed based on 

  ``ASTAKOS_BASE_URL``.

* Management commands:

  * Introduced new commands:

     * authpolicy-{add, list, remove, set, show}

     * group-{add, list}

     * component-{add, list, modify, remove}

     * reconcile-resources-astakos
