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.

98
  * Base quota are now offered through a special purpose user-specific system
99 100 101 102 103
    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.

104
  * In resource creation, project defaults to the user-specific system
105 106 107 108
    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
109
    user-specific system projects.
110

111 112 113 114 115 116 117 118 119
* 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.

120 121 122 123 124 125
* 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.

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.

150 151
  * Field `uplimit' of registed resources is exposed as `system_default' and
    provide the skeleton for user-specific system projects. A new field
152 153 154 155 156 157 158 159 160
    `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.

161 162 163
  * Removed setting `ASTAKOS_PROJECTS_VISIBLE'; we now always display
    projects in Astakos menu.

164 165 166
* Projects can be set `private', making it accessible only to its owner and
  members.

* Admin users API

169 170 171 172 173 174 175
  * Extend astakos identity API to support user management functionality.
  * Admin API related settings
  * ``ADMIN_API_ENABLED``
    Whether or not the admin api endpoints will be enabled.
  * ``ADMIN_API_PERMITTED_GROUPS``
    A list of group names for which users which belong to any of
    them be granted full access to the admin API endpoints.

  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'

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
451 452
    of its `reference' application (current definition). Lock Project rather
    than Chain (the latter is semantically obsolete).
453

454 455 456 457
  * 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'.

458
  * Improve recording of project, application, and membership actions.
459

460
* Implement API calls for projects.
461 462 463 464 465
* 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.
466 467 468 469 470 471 472 473 474 475 476 477 478 479 480
* 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.

481 482
* Remove API call GET /account/v1.0/authenticate in favor of
  POST /identity/v2.0/tokens.
483
* Export basic statistics about Astakos service at the '/admin/stats/detail' API
484 485
  endpoint. Access to this endpoint is only allowed to users that belong to
  the Astakos groups that are defined in the
486
  'ASTAKOS_ADMIN_STATS_PERMITTED_GROUPS' setting. Statistics are also available
487
  through the 'snf-manage stats-astakos' management command.
488 489 490
* 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

    * 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)

506
  * Changed commands:
507 508 509 510 511 512

    * 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

Cyclades
--------

527 528 529
* Major changes to Cyclades networks:

  * Implement 'cyclades_network' service, containing the /networks, /ports,
530 531 532
    /subnets and /floatingips API endpoints under '/network/v2.0'. The old
    /networks API of 'cyclades_compute' (under /compute/v2.0) is
    removed.
533 534 535 536 537
  * 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
538 539
    'CYCLADES_DEFAULT_SERVER_NETWORKS' to control the networks that newly
    created servers will be connected.
540 541 542 543 544 545

* 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}'
546
    management commands to handle floating IPs.
547 548
  * Add 'floating_ip_pool' attribute to networks to mark networks that can
    be used as floating IP pools.

549 550 551 552

* Implement 'resize' server action.

  * Implement the 'resize' server action, to change the flavor of a server.
553
    Only 'cpu' and 'memory' resizing is supported.

554

555
* Compute quotas for CPU and memory of running VMs.
556 557 558 559 560 561 562 563 564

  * 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
565
    to.
566 567 568 569 570 571 572

* 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.
573
* Extend servers info API response with 'SNF:fqdn' attribute, and introduce
574 575
  CYCLADES_SERVERS_FQDN to set the template for servers FDQN. Remove
  'UI_VM_HOSTNAME_FORMAT' setting.
576
* Extend servers info API response with 'SNF:port_forwarding' attribute,
577
  describing port forwarding rules (DNAT) that are applied to vms. The
578 579
  description of such rules is done via the new CYCLADES_PORT_FORWARDING
  setting.
580 581
* Speed up server reconciliation, by performing parallel reconciliation for
  each backend.
582 583
* Change --dhcp option of network management commands from a flag to a boolean
  value, e.g. --dhcp=True
584
* Remove 'ARCHIPELAGO_BACKENDS' setting used to distinguish between backends
585 586
  that hosted only archipelago backends. Instead allocation is based on which
  disk-templates are enabled in each backend.
587
* Implement 'snf-manage server-remove' management command.
588 589 590 591 592 593 594
* 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.
595
* Export basic statistics about Cyclades Service at the '/admin/stats/detail'
596 597
  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'
598
  setting.  Statistics are also available through the 'snf-manage stats-cyclades'
599
  management command.
600 601 602
* Support enforcing quota through command 'enforce-resources-cyclades'.
* Remove command 'resource-export-cyclades' subsumed by
  'service-export-cyclades'.
603 604
* Obsolete PUBLIC_USE_POOL setting, since Cyclades manages IP pool for all
  type of networks.
605 606 607 608 609 610 611 612
* 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.
613 614 615
* 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'.
616 617
* Extend flavors with 'allow_create' attribute. Flavors that have this
  attribute unset cannot be used by users to create new servers.
618 619 620 621 622
* 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

911 912 913 914 915 916 917 918 919 920 921 922

  * 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.
923 924 925
  * Removed settings ASTAKOS_QUOTAHOLDER_URL, ASTAKOS_QUOTAHOLDER_TOKEN,
    and ASTAKOS_QUOTAHOLDER_POOLSIZE.

926 927 928 929 930 931
* 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'.

932 933
* Service and resource specification and handling:

934 935 936 937 938 939 940
  * 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.
941 942 943 944 945 946 947 948 949 950 951 952 953 954 955 956 957 958 959 960 961
  * 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

962 963
* Added fine grain user auth provider's policies.

964
  * Administrator can override default auth provider policies to a specific
965 966 967 968
    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.

969
* Removed explicit handling of SMTP errors on each email delivery. Exceptions
970 971
  are now propagated to base django exception handler.

972 973
* Email used in html/email tempaltes which prompt user to contact for service
  support prompts is now defined in ``CONTACT_EMAIL`` setting introduced in
974 975
  snf-common settings.

976 977 978 979 980
* 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
981
  * Split activation email from moderation process. Administrator is required
982 983
    to moderate user explicitly using the `user-modify --accept` or
    `user-modify --reject` commands.

most of the Synnefo components have been merged into a single repository. Thus,
**just for this version** we will not document a complete Changelog (features,
fixes, improvements, issues, setting changes), but rather just copy from the
`NEWS` file with minor additions wherever needed.
