having a static frontend and retrieving all information via JavaScript, all static information
in the status page is now generated on the node, and JavaScript is only used for dynamic data.
To achieve this, the status page was ported to the gluon-web framework. The new status page
Many status page API endpoints have been removed; for all remaining endpoints, CORS
(Cross-Origin Resource Sharing) has been disabled, as it led to a privacy issues:
malicious websites could access the API via cross-site scripting, determining which
node a user was connected to.
The removal of CORS breaks compatibility with the node switching feature of the
old status page implementation: In the new status page, switching to another node will
reload the whole status page from the target node, while the old implementation would
only switch to another backend host. While this will facilitate future updates, as
frontend and backend always come from the same node and no stable API needs to be maintained,
it prevents switching from the old status page to nodes running the new version.
To achieve all this, the status page was ported to the gluon-web framework. The new status page
also makes use of Gluon's usual i18n facilities now. In addition, the gluon-web-model
package was split out of the gluon-web core package, as model support is only required
for config mode packages, but not for the new status page.
