`Onebox.preview` can return 0-to-n errors, where the errors are missing OpenGraph attributes (e.g. title, description, image, etc.). If any of these attributes are missing, we construct an error message and attach it to the Oneboxer preview HTML. The error message is something like:
“Sorry, we were unable to generate a preview for this web page, because the following oEmbed / OpenGraph tags could not be found: description, image”
However, if the only missing tag is `image` we don’t need to display the error, as we have enough other data (title, description, etc.) to construct a useful/complete Onebox.
Version 2.8 brings some changes to how address fields are handled and
this commits updates that and should also include a fix which handles
encoded attachment filenames.
The fork contains a bugfix to correctly decode mail attachments.
`convert_to_jpeg!` is only called if `convert_png_to_jpeg?` and/or `should_alter_quality?` is true.
`convert_png_to_jpeg?` can be disabled by setting `SiteSetting.png_to_jpg_quality` to 100.
However, `should_alter_quality?` could be true if `SiteSetting.recompress_original_jpg_quality` was lower than the quality of the uploaded file, regardless of file type.
This commits changes `should_alter_quality?` so that uploaded png files will use the `SiteSetting.png_to_jpg_quality` value, rather than ``SiteSetting.recompress_original_jpg_quality` value.
* FEATURE: display error if Oneboxing fails due to HTTP error
- display warning if onebox URL is unresolvable
- display warning if attributes are missing
* FEATURE: Use new Instagram oEmbed endpoint if access token is configured
Instagram requires an Access Token to access their oEmbed endpoint. The requirements (from https://developers.facebook.com/docs/instagram/oembed/) are as follows:
- a Facebook Developer account, which you can create at developers.facebook.com
- a registered Facebook app
- the oEmbed Product added to the app
- an Access Token
- The Facebook app must be in Live Mode
The generated Access Token, once added to SiteSetting.facebook_app_access_token, will be passed to onebox. Onebox can then use this token to access the oEmbed endpoint to generate a onebox for Instagram.

We updated version of moment and moment-timezone as our current versions are outdated making Discourse Dates broken on places where timezone had updates, like here in Brazil.
This also update highlightJS to the latest version and corrected a test that relied on a no longer supported locale in
moment.

This also ensures that restoring a backup works when it was created with the wrong upload paths in the time between ab4c0a4970 (shortly after v2.6.0.beta1) and this fix.
The `EXECUTE FUNCTION` syntax for `CREATE TRIGGER` statements was introduced in PostgreSQL 11. We need to replace `EXECUTE FUNCTION` with `EXECUTE PROCEDURE` in order to be able to restore backups created with PG12 on PG10.
* Also fixes an issue where if webp was a downloaded hotlinked
image and then secure + sent in an email, it was not being
redacted because webp was not a supported media format in
FileHelper
* Webp originally removed as an image format in
https://github.com/discourse/discourse/pull/6377
and there was a spec to make sure a .bin webp
file did not get renamed from its type to webp.
However we want to support webp images now to make
sure they are properly redacted if secure media is
on, so change the example in the spec to use tiff,
another banned format, instead
This is not used in core or official plugins, and has been printing a deprecation notice since v2.3.0beta4. All OpenID 2.0 code and dependencies have been dropped. The user_open_ids table remains for now, in case anyone has missed the deprecation notice, and needs to migrate their data.

* UI: Mass grant a badge from the admin ui
* Send the uploaded CSV and badge ID to the backend
* Read the CSV and grant badge in batches
* UX: Communicate the result to the user
* Don't award if badge is disabled
* Create a 'send_notification' method to remove duplicated code, slightly shrink badge image. Replace router transition with href.
* Dynamically discover current route
This feature is off by default and can can be configured with the `email_total_attachment_size_limit_kb` site setting.

This removes all uses of both `send` and `public_send` from consumers of
SiteSetting and instead introduces a `get` helper for dynamic lookup
This leads to much cleaner and safer code long term as we are always explicit
to test that a site setting is really there before sending an arbitrary
string to the class
It also removes a couple of risky stubs from the auth provider test
This change automatically resizes icons for various purposes. Admins can now upload `logo` and `logo_small`, and everything else will be auto-generated. Specific icons can still be uploaded separately if required.
## Core
- Adds an SiteIconManager module which manages automatic resizing and fallback
- Icons are looked up in the OptimizedImage table at runtime, and then cached in Redis. If the resized version is missing for some reason, then most icons will fall back to the original files. Some icons (e.g. PWA Manifest) will return `nil` (because an incorrectly sized icon is worse than a missing icon).
- `SiteSetting.site_large_icon_url` will return the optimized version, including any fallback. `SiteSetting.large_icon` continues to return the upload object. This means that (almost) no changes are required in core/plugins to support this new system.
- Icons are resized whenever a relevant site setting is changed, and during post-deploy migrations
## Wizard
- Allows `requiresRefresh` wizard steps to reload data via AJAX instead of a full page reload
- Add placeholders to the **icons** step of the wizard, which automatically update from the "Square Logo"
- Various copy updates to support the changes
- Remove the "upload-time" resizing for `large_icon`. This is no longer required.
## Site Settings UX
- Move logo/icon settings under a new "Branding" tab
- Various copy changes to support the changes
- Adds placeholder support to the `image-uploader` component
- Automatically reloads site settings after saving. This allows setting placeholders to change based on changes to other settings
- Upload site settings will be assigned a placeholder if SiteIconManager `responds_to?` an icon of the same name
## Dashboard Warnings
- Remove PWA icon and PWA title warnings. Both are now handled automatically.
## Bonus
- Updated the sketch logos to use @awesomerobot's new high-res designs
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

Uses github.com/discourse/moment-timezone-names-translations to translate timezone names.
Plugins can also provide their own timezone name translations.
This feature ensures optimized images run via pngquant, this results extreme amounts of savings for resized images. Effectively the only impact is that the color palette on small resized images is reduced to 256.
To ensure safety we only apply this optimisation to images smaller than 500k.
This commit also makes a bunch of image specs less fragile.
* FEATURE: allow plugins and themes to extend the default CSP
For plugins:
```
extend_content_security_policy(
script_src: ['https://domain.com/script.js', 'https://your-cdn.com/'],
style_src: ['https://domain.com/style.css']
)
```
For themes and components:
```
extend_content_security_policy:
type: list
default: "script_src:https://domain.com/|style_src:https://domain.com"
```
* clear CSP base url before each test
we have a test that stubs `Rails.env.development?` to true
* Only allow extending directives that core includes, for now
This also adjusts the algorithm to expect
- 30% saving for JPEG conversion
AND
- Minimum of 75K bytes saved
The reasoning for increase of saving requirements is cause PNG may have been
uploaded unoptimized, 30% saving on PNG is very possible
This moves us away from the delayed drops pattern which
was problematic on two counts. First, it uses a hardcoded "delay for"
duration which may be too short for certain deployment strategies.
Second, delayed drop doesn't ensure that it only runs after
the latest application code has been deployed. If the migration runs
and the application code fails to deploy, running the migration after
"delay for" has been met will cause the application to blow up.
The new strategy allows post deployment migrations to be skipped if the
env `SKIP_POST_DEPLOYMENT_MIGRATIONS` is provided.
```
SKIP_POST_DEPLOYMENT_MIGRATIONS=1 rake db:migrate
-> deploy app servers
SKIP_POST_DEPLOYMENT_MIGRATIONS=0 rake db:migrate
```
To aid with the generation of a post deployment migration, a generator
has been added. Simply run `rails generate post_migration`.
In the past the filename of the origin was used as the source
for the extension of the file when optimizing on upload.
We now use the actual calculated extension based on upload data.
At the moment core providers are hard-coded in Javascript, and plugin providers get added to the JS payload at compile time. This refactor means that we only ship enabled providers to the client.
* Add possibility to add hidden posts with PostCreator
* FEATURE: Create hidden posts for received spam emails
Spamchecker usually have 3 results: HAM, SPAM and PROBABLY_SPAM
SPAM gets usually directly rejected and needs no further handling.
HAM is good message and usually gets passed unmodified.
PROBABLY_SPAM gets an additional header to allow further processing.
This change addes processing capabilities for such headers and marks
new posts created as hidden when received via email.
Often we need to amend our schema, it is tempting to use
drop_table, rename_column and drop_column to amned schema
trouble though is that existing code that is running in production
can depend on the existance of previous schema leading to application
breaking until new code base is deployed.
The commit enforces new rules to ensure we can never drop tables or
columns in migrations and instead use Migration::ColumnDropper and
Migration::TableDropper to defer drop the db objects
In the past we used suppress_from_homepage, it had mixed semantics
it would remove from category list if category list was on home and
unconditionally remove from latest.
New setting explicitly only removes from latest list but leaves the
category list alond
* SPEC: PollFeedJob parsing atom feed
* add FeedItemAccessor
It is to provide a consistent interface to access a feed item's tag
content.
* add FeedElementInstaller
to install non-standard and non-namespaced feed elements
* FEATURE: replace SimpleRSS with Ruby RSS module
* get FinalDestination and download with Excon
* support namespaced element with FeedElementInstaller
This change-set allows setting different defaults for different locales.
It also:
- Adds extensive testing around site setting validation
- raises deprecation error if site setting has the default property based on env
- relocated site settings for dev and tests in the initializer
- deprecated client_setting in the site setting's loading process
- ensure it raises when a enum site setting being set
- default_locale is promoted to `required` category.
- fixes incorrect default setting and validation
- fixes ensure type check for site settings
- creates a benchmark for site setting
- sets reasonable defaults for Chinese
The mail class seems to handle mails sent with Content-Transfer-Encoding: 8bit
somewhat weirdly: It decodes them (to utf-8), changes the raw source to base64,
and does not modify the Content-Type:charset= header.
This leads to Discourse trying the message encoding (in my example ISO-8859-1)
first, and if that does not contain any unparseable characters, it uses that.
Sadly, in ISO-8859-1, every byte sequence is valid.
Fix this by always trying to decode as UTF-8 first. The probability of someone
using another encoding that cleanly (but wrongly) decodes as UTF-8 should be
fairly low.
