-------

* Support LDAP authentication by creating the 'LDAP' authentication
  provider.
* Add 'autoverify' provider policy to automatically verify the user's
  email. Obsolete the 'SKIP_EMAIL_VERIFICATION' setting.
* Extend authentication provider mechanism to support mapping arbitraty
  provider's attributes to user attributes. Also, support making these
  attributes to be 'forced' by the provider so that user cannot change
  them (e.g. the user's email).

  of 'identity/v2.0/tokens' API call.

Cyclades
--------

* Implement shared resources among members of a project.

  * Extend Cyclades API with the 'shared_to_project' field, indicating whether
  a resource is shared to the members of the project that the resource belongs
  to.
  * Extend `reassign` API call with the 'shared_to_project' field that can be
  used to share or unshare a resource to project members.
  * Update Cyclades API to return all resources that are accessible to a user,
  and not only those that are owned by the user.
  * Update snf-manage commands to show whether a resource is shared or not.


Cyclades UI
-----------

* Extend Cyclades UI to work with shared resources

 * Add option to share/unshare a resource in the project reassign view.
 * Add icons to distinquish resources that are either shared by the user
 or a shared to the user.
 * Properly handle ghost resources, which are resources that are visible to
 the user only because they are related with some shared resource, but the
 user has no access to them. Add tooltip to explain this to the user.

203 204 205 206 207 208 209 210 211

Synnefo-wide
------------

* Replace accumulative projects with pool projects:

  * Projects are now viewed as a source of finite resources. A member can
    reserve a part of these resources up to a specified limit.

212
  * Base quota are now offered through a special purpose user-specific system
213 214 215 216 217
    project, identified with the same UUID as the user.

  * Each actual resource (Cyclades VM, network, floating IP and Pithos
    container) is now also associated with a project besides the owner.

218
  * In resource creation, project defaults to the user-specific system
219 220 221 222
    project, if not specified otherwise. It is also possible to change the
    project assignment of an existing resource.

  * All existing resources have been assigned to the respective
223
    user-specific system projects.
224

225 226 227 228 229 230 231 232 233
* Logging mechanism for Synnefo management commands

  * Log all stdout and stderr output of every invocation of snf-manage,
    on unique filenames under a given directory.

  * Add a new setting in the snf-common package, namely 'LOG_DIR', which
    specifies the directory to be used by Synnefo components to write
    their log files.

234 235 236 237 238 239
* Rename argument names of Synnefo management commands

  * All Synnefo management commands now use 'user/flavor/image/network'
    as argument names, instead of 'userid/user-id/owner/flavor-id/image
    -id/network-id', for consistency across commands.

240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263
Astakos
-------

* Decouple projects from applications:

  * Support project creation (by the system) and modification (by a
    privileged user) without the need to submit/approve an application.

  * View applications as modifications. When a project is uninitialized
    (e.g. an application for a new project is pending), no further
    modification is allowed.

  * Applications are removed from the API. A project's last application is
    only accessible as part of the project details.

  * Decouple project state from application state; they can be combined by
    an API client, if needed.

* Changes concerning quota and pool projects:

  * A project must provide limits for all registered resources. On project
    activation, resources missing are automatically completed using a
    skeleton.

264 265
  * Field `uplimit' of registed resources is exposed as `system_default' and
    provide the skeleton for user-specific system projects. A new field
266 267 268 269 270 271 272 273 274
    `project_default' is introduce to act as a skeleton for conventional
    projects.

  * The quotaholder now also records project quota besides user quota. The
    two types of holders are distinguished with a prefix: `user:' and
    `project:'.

  * The quota API is extended to make project quota available.

275 276 277
  * Removed setting `ASTAKOS_PROJECTS_VISIBLE'; we now always display
    projects in Astakos menu.

278 279 280
* Projects can be set `private', making it accessible only to its owner and
  members.

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
565 566
    of its `reference' application (current definition). Lock Project rather
    than Chain (the latter is semantically obsolete).
567

568 569 570 571
  * 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'.

572
  * Improve recording of project, application, and membership actions.
573

574
* Implement API calls for projects.
575 576 577 578 579
* 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.
580 581 582 583 584 585 586 587 588 589 590 591 592 593 594
* 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.

595 596
* Remove API call GET /account/v1.0/authenticate in favor of
  POST /identity/v2.0/tokens.
597
* Export basic statistics about Astakos service at the '/admin/stats/detail' API
598 599
  endpoint. Access to this endpoint is only allowed to users that belong to
  the Astakos groups that are defined in the
600
  'ASTAKOS_ADMIN_STATS_PERMITTED_GROUPS' setting. Statistics are also available
601
  through the 'snf-manage stats-astakos' management command.
602 603 604
* 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

  the third-party provider.
609
* Management commands:
610

611
  * Introduced new commands:
612 613 614 615 616 617 618 619

    * 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)

620
  * Changed commands:
621 622 623 624 625 626

    * 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

627
  * Removed commands:
628 629 630 631 632 633 634 635 636

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

* Fix request authorization code failures due to Unicode issue:
  https://code.grnet.gr/issues/4971
* Omit validation issues for non-required metadata values received from the
  third-party authentication provider.
637

638 639 640
Cyclades
--------

641 642 643
* Major changes to Cyclades networks:

  * Implement 'cyclades_network' service, containing the /networks, /ports,
644 645 646
    /subnets and /floatingips API endpoints under '/network/v2.0'. The old
    /networks API of 'cyclades_compute' (under /compute/v2.0) is
    removed.
647 648 649 650 651
  * 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
652 653
    'CYCLADES_DEFAULT_SERVER_NETWORKS' to control the networks that newly
    created servers will be connected.
654 655 656 657 658 659

* 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}'
660
    management commands to handle floating IPs.
661 662
  * Add 'floating_ip_pool' attribute to networks to mark networks that can
    be used as floating IP pools.

668

669
* Compute quotas for CPU and memory of running VMs.
670 671 672 673 674 675 676 677 678

  * 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
679
    to.
680 681 682 683 684 685 686

* 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.
687
* Extend servers info API response with 'SNF:fqdn' attribute, and introduce
688 689
  CYCLADES_SERVERS_FQDN to set the template for servers FDQN. Remove
  'UI_VM_HOSTNAME_FORMAT' setting.
690
* Extend servers info API response with 'SNF:port_forwarding' attribute,
691
  describing port forwarding rules (DNAT) that are applied to vms. The
692 693
  description of such rules is done via the new CYCLADES_PORT_FORWARDING
  setting.
694 695
* Speed up server reconciliation, by performing parallel reconciliation for
  each backend.
696 697
* Change --dhcp option of network management commands from a flag to a boolean
  value, e.g. --dhcp=True
698
* Remove 'ARCHIPELAGO_BACKENDS' setting used to distinguish between backends
699 700
  that hosted only archipelago backends. Instead allocation is based on which
  disk-templates are enabled in each backend.
701
* Implement 'snf-manage server-remove' management command.
702 703 704 705 706 707 708
* 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.
709
* Export basic statistics about Cyclades Service at the '/admin/stats/detail'
710 711
  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'
712
  setting.  Statistics are also available through the 'snf-manage stats-cyclades'
713
  management command.
714 715 716
* Support enforcing quota through command 'enforce-resources-cyclades'.
* Remove command 'resource-export-cyclades' subsumed by
  'service-export-cyclades'.
717 718
* Obsolete PUBLIC_USE_POOL setting, since Cyclades manages IP pool for all
  type of networks.
719 720 721 722 723 724 725 726
* 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.
727 728 729
* 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'.
730 731
* Extend flavors with 'allow_create' attribute. Flavors that have this
  attribute unset cannot be used by users to create new servers.
732 733 734 735 736
* Store each image property(metadata) as a separate Pithos metadata and check
  that the size of each property is valid.
* Fix a few occurrences of HTTP 500 errors being triggered due to insufficient
  validation of incoming requests in the Network API
* Speed up some API calls by fixing the relevant DB queries

  * 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.

1048 1049 1050 1051 1052 1053 1054
  * 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'.

    their resources in astakos and set the resources' default base quota
    limit. Removed resource definitions from settings.

    models into a separate file of UI constants.

  resource. Converted the related user setting to a user-specific base quota
  limit. Deprecated model UserSetting; removed setting

* 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

    address.
  * User model enriched with additional user state fields
1095
