This -appears in two primary places: the Networks panel in both the Project and -Admin dashboards, and the Network tab in the Launch Instance workflow. Expect -further improvements in these areas as Quantum continues to mature and more -users adopt this model of virtual network management. - -User Experience ---------------- - -Workflows -~~~~~~~~~ - -By far the biggest UI/UX change in the Folsom release is the introduction of -programmatic workflows. These components allow developers to create concise -interactions that combine discrete tasks spanning multiple services and -resources in a user-friendly way and with minimal boilerplate code. Within -a workflow, related objects can also be dynamically created so users don't lose -their place when they realize the item they wanted isn't currently available. -Look for examples of these workflows in Launch Instance, Associate Floating IP, -and Create/Edit Project. - -Resource Browser -~~~~~~~~~~~~~~~~ - -Another cool new component is an interface designed for "browsing" resources -which are nested under a parent resource. The object store (Swift) is a prime -example of this. Now there is a consistent top-level navigation for containers -on the left-hand pane of the "browser" while the right-hand pane lets you -explore within those containers and sub-folders. - -User Experience Improvements ----------------------------- - -* Timezone support is now enabled. You can select your preferred timezone - in the User Settings panel. - -Community ---------- - -* Third-party developers who wish to build on Horizon can get started much - faster using the new dashboard and panel templates. See the docs on - `creating a dashboard`_ and `creating a panel`_ for more information. - -* A `thorough set of documentation`_ for developers on how to go about - internationalizing, localizing and translating OpenStack projects - is now available. - -.. _creating a dashboard: http://docs.openstack.org/developer/horizon/topics/tutorial.html#creating-a-dashboard -.. _creating a panel: http://docs.openstack.org/developer/horizon/topics/tutorial.html#creating-a-panel -.. _thorough set of documentation: http://wiki.openstack.org/Translations - -Under The Hood --------------- - -* The python-swiftclient library and python-cinderclient libraries are now - used under the hood instead of cloudfiles and python-novaclient respectively. - -* Internationalization of client-side JavaScript is now possible in addition - to server-side Python code. - -* Keystone authentication is now handled by a proper pluggable Django - authentication backend, offering significantly better and more reliable - security for Horizon. - -Other Improvements and Fixes ----------------------------- - -Some of the general areas of improvement include: - -* Images can now be added to Glance by providing a URL for Glance to download - the image data from. - -* Quotas are now displayed dynamically throughout the Project dashboard. - -* API endpoints are now displayed on the OpenStack RC File panel so they - can be organically discovered by an end-user. - -* DataTables now support a summation row at the bottom of the table. - -* Better cross-browser support (Safari and IE particularly). - -* Fewer API calls to OpenStack endpoints (improves performance). - -* Better validation of what actions are permitted when. - -* Improved error handling and error messages. - -Known Issues and Limitations -============================ - -Floating IPs and Quantum ------------------------- - -Due to the very late addition of floating IP support in Quantum, Nova's -integration there is lacking, so floating IP-related API calls to Nova will -fail when your OpenStack deployment uses Quantum for networking. This means -that Horizon actions such as "allocate" and "associate" floating IPs will -not work either since they rely on the underlying APIs. - -Pagination ----------- - -A number of the "index" pages don't fully work with API pagination yet, -causing them to only display the first chunk of results returned by the API. -This number is often 1000 (as in the case of novaclient results), but does vary -somewhat. - -Deleting large numbers of resources simultaneously --------------------------------------------------- - -Using the "select all" checkbox to delete large numbers of resources via the -API can cause network timeouts (depending on configuration). This is -due to the APIs not supporting bulk-deletion natively, and consequently Horizon -has to send requests to delete each resource individually behind the scenes. - -Backwards Compatibility -======================= - -The Folsom Horizon release should be fully-compatible with both Folsom and -Essex versions of the rest of the OpenStack core projects (Nova, Swift, etc.). -While some features work significantly better with an all-Folsom stack due -to bugfixes, etc. in underlying services, there should not be any limitations -on what will or will not function. (Note: Quantum was not a core OpenStack -project in Essex, and thus this statement does not apply to network management.) - -In terms of APIs provided for extending Horizon, there are a handful of -backwards-incompatible changes that were made: - -* The ``can_haz`` and ``can_haz_list`` template filters have been renamed - to ``has_permissions`` and ``has_permissions_on_list`` respectively. - -* The dashboard-specific ``base.html`` templates (e.g. ``nova/base.html``, - ``syspanel/base.html``, etc.) have been removed in favor of a single - ``base.html`` template. - -* In conjunction with the previous item, the dashboard-specific template blocks - (e.g. ``nova_main``, ``syspanel_main``, etc.) have been removed in favor of - a single ``main`` template block. - -Overall, though, great effort has been made to maintain compatibility for -third-party developers who may have built on Horizon so far.
