In some restricted setups all JS payloads need tight control.
This setting bans admins from making changes to JS on the site and
requires all themes be whitelisted to be used.
There are edge cases we still need to work through in this mode
hence this is still not supported in production and experimental.
Use an example like this to enable:
`DISCOURSE_WHITELISTED_THEME_REPOS="https://repo.com/repo.git,https://repo.com/repo2.git"`
By default this feature is not enabled and no changes are made.
One exception is that default theme id was missing a security check
this was added for correctness.
* FIX: randomize file name when created from fixtures
When a temporary file is created from fixtures it should have a unique name.
It is to prevent a collision in parallel specs evaluation
* FIX: use /tmp/pid folder to keep fixture files
### General Changes and Duplication
* We now consider a post `with_secure_media?` if it is in a read-restricted category.
* When uploading we now set an upload's secure status straight away.
* When uploading if `SiteSetting.secure_media` is enabled, we do not check to see if the upload already exists using the `sha1` digest of the upload. The `sha1` column of the upload is filled with a `SecureRandom.hex(20)` value which is the same length as `Upload::SHA1_LENGTH`. The `original_sha1` column is filled with the _real_ sha1 digest of the file.
* Whether an upload `should_be_secure?` is now determined by whether the `access_control_post` is `with_secure_media?` (if there is no access control post then we leave the secure status as is).
* When serializing the upload, we now cook the URL if the upload is secure. This is so it shows up correctly in the composer preview, because we set secure status on upload.
### Viewing Secure Media
* The secure-media-upload URL will take the post that the upload is attached to into account via `Guardian.can_see?` for access permissions
* If there is no `access_control_post` then we just deliver the media. This should be a rare occurrance and shouldn't cause issues as the `access_control_post` is set when `link_post_uploads` is called via `CookedPostProcessor`
### Removed
We no longer do any of these because we do not reuse uploads by sha1 if secure media is enabled.
* We no longer have a way to prevent cross-posting of a secure upload from a private context to a public context.
* We no longer have to set `secure: false` for uploads when uploading for a theme component.
* FEATURE: Ability to add components to all themes
This is the first and functional step from that topic https://dev.discourse.org/t/adding-a-theme-component-is-too-much-work/15398/16
The idea here is that when a new component is added, the user can easily assign it to all themes (parents).
To achieve that, I needed to change a site-setting component to accept `setDefaultValues` action and `setDefaultValuesLabel` translated label.
Also, I needed to add `allowAny` option to disable that for theme selector.
I also refactored backend to accept both parent and child ids with one method to avoid duplication (Renamed `add_child_theme!` to more general `add_relative_theme!`)
* FIX: Improvement after code review
* FIX: Improvement after code review2
* FIX: use mapBy and filterBy directly
When uploading a file to a theme component, and that file is existing and has already been marked as secure, we now automatically mark the file as secure: false, change the ACL, and log the action as the user (also rebake the posts for the upload)
* FEATURE: Adds an extra protection layer when decompressing files.
* Rename exporter/importer to zip importer. Update old locale
* Added a new composite class to decompress a file with multiple strategies
* Set max file size inside a site setting
* Ensure that file is deleted after compression
* Sanitize path and files before compressing/decompressing
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
The client-side theme-selector would always apply the first in a series of file change notifications. This has been fixed, so it now applies the most recent notification.
Duplicate notifications were being sent because
- The remote_theme autosave was causing every change notification to be doubled
- Color scheme change notifications were being sent every time a theme was uploaded, even if the colors were unchanged
These duplicate notifications have been fixed, and a spec added to ensure it does not regress in future
* Revert "Revert "FEATURE: admin/user exports are compressed using the zip format (#7784)""
This reverts commit f89bd55576.
* Replace .tar.zip with .zip
* FEATURE: admin/user exports are compressed using the zip format
* Update translations. Theme exporter now exports .zip file. Theme importer supports .zip and .gz files
* Fix controller test, updated locale and skip saving the csv export to disk
This allows you to temporarily disable components without having to remove them from a theme.
This feature is very handy when doing quick fix engineering.
* Introduced fab!, a helper that creates database state for a group
It's almost identical to let_it_be, except:
1. It creates a new object for each test by default,
2. You can disable it using PREFABRICATION=0
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
Currently the theme is matched by name, which can be fragile when there are many themes with the same name. This functionality will be used by the next version of theme CLI.
- Themes can supply translation files in a format like `/locales/{locale}.yml`. These files should be valid YAML, with a single top level key equal to the locale being defined. For now these can only be defined using the `discourse_theme` CLI, importing a `.tar.gz`, or from a GIT repository.
- Fallback is handled on a global level (if the locale is not defined in the theme), as well as on individual keys (if some keys are missing from the selected interface language).
- Administrators can override individual keys on a per-theme basis in the /admin/customize/themes user interface.
- Theme developers should access defined translations using the new theme prefix variables:
JavaScript: `I18n.t(themePrefix("my_translation_key"))`
Handlebars: `{{theme-i18n "my_translation_key"}}` or `{{i18n (theme-prefix "my_translation_key")}}`
- To design for backwards compatibility, theme developers can check for the presence of the `themePrefix` variable in JavaScript
- As part of this, the old `{{themeSetting.setting_name}}` syntax is deprecated in favour of `{{theme-setting "setting_name"}}`
* 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
