This commit adds a new property "discourseReferrerPolicy" to the
set of supported configuration properties for the comment embed
script. If provided the value will be used to set the "referrerPolicy"
attribute on the iframe created to display the comments. This in turn
will allow embedding pages to define a more lenient referer policy on
the embed iframe for pages whose default policy is so strict it
keeps the comment embed from working.
Example:
* Setup:
* Discourse hosted at discourse.example.com
* Comments embedded at example.com
* Referrer-Policy at example.com set to 'same-origin'
* Without this commit:
* Loading the comments fails due to the referer being empty
* With this commit and no adjusted configuration:
* Loading the comments fails due to the referer being empty
(= same behaviour as without the commit)
* With this commit and DiscourseEmbed.discourseReferrerPolicy =
'no-referrer-when-downgrade' as additional configuration:
* Loading the comments succeeds
Note that this change is of special interest for embedding pages
wanting to restrict data flows under the terms of the GDPR since
it allows selectively whitelisting comment embeds while preventing
referer leaking by default.
This is the first iteration of an effort towards making a very good dashboard.
Until we feel confident this is good, this dashboard will only be accessible through /admin/dashboard_next
This feature introduces the concept of themes. Themes are an evolution
of site customizations.
Themes introduce two very big conceptual changes:
- A theme may include other "child themes", children can include grand
children and so on.
- A theme may specify a color scheme
The change does away with the idea of "enabled" color schemes.
It also adds a bunch of big niceties like
- You can source a theme from a git repo
- History for themes is much improved
- You can only have a single enabled theme. Themes can be selected by
users, if you opt for it.
On a technical level this change comes with a whole bunch of goodies
- All CSS is now compiled using a custom pipeline that uses libsass
see /lib/stylesheet
- There is a single pipeline for css compilation (in the past we used
one for customizations and another one for the rest of the app
- The stylesheet pipeline is now divorced of sprockets, there is no
reliance on sprockets for CSS bundling
- CSS is generated with source maps everywhere (including themes) this
makes debugging much easier
- Our "live reloader" is smarter and avoid a flash of unstyled content
we run a file watcher in "puma" in dev so you no longer need to run
rake autospec to watch for CSS changes
Feature to allow each imported post to be created using a different discourse
username. A possible use case of this is a multi-author blog where discourse
is being used to track comments. This feature allows authors to receive
updates when someone leaves a comment on one of their articles because each of
the imported posts can be created using the discourse username of the author.
