* Phase 0 for user-selectable theme components
- Drops `key` column from the `themes` table
- Drops `theme_key` column from the `user_options` table
- Adds `theme_ids` (array of ints default []) column to the `user_options` table and migrates data from `theme_key` to the new column.
- Removes the `default_theme_key` site setting and adds `default_theme_id` instead.
- Replaces `theme_key` cookie with a new one called `theme_ids`
- no longer need Theme.settings_for_client
- Remove share target because the spec is changing
- Allow any orientation again because natural is too restrictive
- Use correct file and mime types for the manifest
* Add user_home configuration option
* Use the new user_home preference to actually show the right home page
* Fix trailing whitespace
* Update user_option_serializer.rb
* Fix JavaScript default homepage tests
* Use an object instead of a giant switch
* Remove trailing whitespace
* Make the default `user_home` set to `null` instead of `0`
* Rename user_home to homepage_id
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
<% s=Time.now;
main_app.categories_path
main_app.guidelines_path
main_app.tos_path
main_app.privacy_path
p (Time.now-s)*1000%>
Returns 10-20ms consistently on i7-4770k, on shared hosts the cost
could easily reach 40ms
This code simply calculates the strings
/categories
/guidelines
/tos
/privacy
It is ludicrous to spend this enormous amount of work just to calculate
4 strings.
I do not know if this is something specific about Discourse or a bug in
Rails (I tried without the main_app prefix and got similar results),
regardless we can got to avoid these _path APIs for now
Discovered this when running a flamegraph on our home page.
Our plugins use rails engines which are mounted against the main
application's `ApplicationController`. This works great but path helpers
need to reference `main_app` in order for it not to blow up.
- add microdata based on schema.org
- add breadcrumb on the top of topic
- add navigations link on the bottom of every pages
- add category description on the category list
- FIX: make sure we set a default name to a pasted image only on Chrome (the only browser that supports it)
- FIX: use ".json" extension to uploads endpoints since IE9 doesn't pass the correct header
- FIX: pass the CSRF token in a query parameter since IE9 doesn't pass it in the headers
- FIX: display error messages comming from the server when there is one over the default error message
- FIX: HACK around IE9 security issue when clicking a file input via JavaScript (use a label and set `visibility:hidden` on the input)
- FIX: hide the "cancel" upload on IE9 since it's not supported
- FIX: return "text/plain" content-type when uploading a file for IE9 in order to prevent it from displaying the save dialog
- FIX: check the maximum file size on the server 💥
- update jQuery File Upload Plugin to v. 5.42.2
- update JQuery IFram Transport Plugin to v. 1.8.5
- update jQuery UI Widget to v. 1.11.1
Added the site setting long_polling_base_url , this allows you
to farm long polling to a different server.
This setting is very important if a CDN is serving dynamic content.
