This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
If a user is created with an id of 999, a `upload.user_id ==
user_avatar.user_id` will return true. This fix increases the id of the
upload to something that we will not hit in the foreseeable future.
Adds a new topic_excerpt_maxlength site setting.
* When topic excerpt is requested for a post, use the new topic_excerpt_maxlength site setting to limit the size of the excerpt
* Remove code for getting/setting Post.excerpt_size as it is not used anywhere
In some cases, between Discourse forums the hostname of a URL could match if they are hosting S3 files on the same bucket but the S3 bucket path might not. So e.g. https://testbucket.somesite.com/testpath/some/file/url.png vs https://testbucket.somesite.com/prodpath/some/file/url.png. So has_been_uploaded? was returning true for the second URL, even though it may have been uploaded on a different Discourse forum.
This is a very rare case but must be accounted for, because this impacts UrlHelper.is_local which mistakenly thinks the file has already been downloaded and thus allows the URL to be cooked, where we want to return the full URL to be downloaded using PullHotlinkedImages.
* DEV: Add framework for filtered plugin registers
Plugins often need to add values to a list, and we need to filter those lists at runtime to ignore values from disabled plugins. This commit provides a re-usable way to do that, which should make it easier to add new registers in future, and also reduce repeated code.
Follow-up commits will migrate existing registers to use this new system
* DEV: Migrate user and group custom field APIs to plugin registry
This gives us a consistent system for checking plugin enabled state, so we are repeating less logic. API changes are backwards compatible
* DEV: Standardize table sorting verbiage
This commit creates a common component that tables can use to make their
headers sortable. This commit also standardizes on using `desc` as the
default and passing in the `asc=true` flag to adjust the sorting
direction.
* Add deprecation warnings
Adds deprecation warnings if using previous params and maintains
backwards compatibility. Set the default sort value for group members to
be asc.
* switch group requests to use common table-header-toggle
* update fixture
* PERF: Dematerialize topic_reply_count
It's only ever used for trust level promotions that run daily, or compared to 0. We don't need to track it on every post creation.
* UX: Add symbol in TL3 report if topic reply count is capped
* DEV: Drop user_stats.topic_reply_count column
Use a helper method to simplify creating a new register. Previously this would require creating lots of different methods manually, and adding every register to the clear/reset functions
This refactors default_current_user_provider in a few ways:
- Introduce a generic `api_parameter_allowed?` method which checks for whitelisted routes/formats
- Only read the api_key parameter on allowed routes. It is now completely ignored on other routes (previously it would raise a 403)
- Start reading user_api_key parameter on allowed routes
- Refactor tests as end-end integration tests
A plugin API for PARAMETER_API_PATTERNS will be added soon
There were two constants here, `INLINE_ONEBOX_LOADING_CSS_CLASS` and
`INLINE_ONEBOX_CSS_CLASS` that were both longer than the strings they
were DRYing up: `inline-onebox-loading` and `inline-onebox`
I normally appreciate constants, but in this case it meant that we had
a lot of JS imports resulting in many more lines of code (and CPU cycles
spent figuring them out.)
It also meant we had an `.erb` file and had to invoke Ruby to create the
JS file, which meant the app was harder to port to Ember CLI.
I removed the constants. It's less DRY but faster and simpler, and
arguably the loss of DRYness is not significant as you can still search
for the `inline-onebox-loading` and `inline-onebox` strings easily if
you are refactoring.
Locale files get precompiled after deployment and they contained translations from the `default_locale`. That's especially bad in multisites, because the initial `default_locale` is `en_US`. Sites where the `default_locale` isn't `en_US` could see missing translations. The same thing could happen when users are allowed to chose a different locale.
This change simplifies the logic by not using the `default_locale` in the locale chain. It always falls back to `en` in case of missing translations.
The failover spec is very fragile and tests specific implementation
vs actual behavior
We rely on a different script during the build process to test
failover operates correctly
This introduces new APIs for obtaining optimized thumbnails for topics. There are a few building blocks required for this:
- Introduces new `image_upload_id` columns on the `posts` and `topics` table. This replaces the old `image_url` column, which means that thumbnails are now restricted to uploads. Hotlinked thumbnails are no longer possible. In normal use (with pull_hotlinked_images enabled), this has no noticeable impact
- A migration attempts to match existing urls to upload records. If a match cannot be found then the posts will be queued for rebake
- Optimized thumbnails are generated during post_process_cooked. If thumbnails are missing when serializing a topic list, then a sidekiq job is queued
- Topic lists and topics now include a `thumbnails` key, which includes all the available images:
```
"thumbnails": [
{
"max_width": null,
"max_height": null,
"url": "//example.com/original-image.png",
"width": 1380,
"height": 1840
},
{
"max_width": 1024,
"max_height": 1024,
"url": "//example.com/optimized-image.png",
"width": 768,
"height": 1024
}
]
```
- Themes can request additional thumbnail sizes by using a modifier in their `about.json` file:
```
"modifiers": {
"topic_thumbnail_sizes": [
[200, 200],
[800, 800]
],
...
```
Remember that these are generated asynchronously, so your theme should include logic to fallback to other available thumbnails if your requested size has not yet been generated
- Two new raw plugin outlets are introduced, to improve the customisability of the topic list. `topic-list-before-columns` and `topic-list-before-link`
Recently, we added feature that we are sending `/muted` to users who muted specific topic just before `/latest` so the client knows to ignore those messages - https://github.com/discourse/discourse/pull/9482
Same `/muted` message should be included when the post is edited
TLDR; this commit vastly improves how whitespaces are handled when converting from HTML to Markdown.
It also adds support for converting HTML <tables> to markdown tables.
The previous 'remove_whitespaces!' method was traversing the whole HTML tree and used a heuristic to remove
leading and trailing whitespaces whenever it was appropriate (ie. mostly before and after HTML block elements)
It was a good idea, but it was very limited and leaded to bad conversion when the html had leading whitespaces on several lines for example.
One such example can be found [here](https://meta.discourse.org/t/86782).
For various reasons, most of the whitespaces in a HTML file is ignored when the page is being displayed in a browser.
The rules that the browsers follow are the [CSS' White Space Processing Rules](https://www.w3.org/TR/css-text-3/#white-space-rules).
They can be quite complicated when you take into account RTL languages and other various tidbits but they boils down to the following:
- Collapse whitespaces down to one space (0x20) inside an inline context (ie. nodes/tags that are being displaying on the same line)
- Remove any leading/trailing whitespaces inside an inline context
One quick & dirty way of getting this 90% solved would be to do 'HTML.gsub!(/[[:space:]]+/, " ")'.
We would also need to hoist <pre> elements in order to not mess with their whitespaces.
Unfortunately, this solution let some whitespaces creep around HTML tags which leads to more '.strip!' calls than I can bear.
I decided to "emulate" the browser's handling of whitespaces and came up with a solution in 4 parts
1. remove_not_allowed!
The HtmlToMarkdown library is recursively "visiting" all the nodes in the HTML in order to convert them to Markdown.
All the nodes that aren't handled by the library (eg. <script>, <style> or any non-textual HTML tags) are "swallowed".
In order to reduce the number of nodes visited, the method 'remove_not_allowed!' will automatically delete all the nodes
that have no "visitor" (eg. a 'visit_<tag>' method) defined.
2. remove_hidden!
Similar purpose as the previous method (eg. reducing number of nodes visited), there's no point trying to convert something that is hidden.
The 'remove_hidden!' method removes any nodes that was hidden using the "hidden" HTML attribute, some CSS or with a width or height equal to 0.
3. hoist_line_breaks!
The 'hoist_line_breaks!' method is there to handle <br> tags. I know those tiny <br> don't do much but they can be quite annoying.
The <br> tags are inline elements but they visually work like a block element (ie. they create a new line).
If you have the following HTML "<i>Foo<br>Bar</i>", it ends up visually similar to "<i>Foo</i><br><i>Bar</i>".
The latter being much more easy to process than the former, so that's what this method is doing.
The "hoist_line_breaks" will hoist <br> tags out of inline tags until their parent is a block element.
4. remove_whitespaces!
The "remove_whitespaces!" is where all the whitespace removal is happening. It's broken down into 4 methods as well
- remove_whitespaces!
- is_inline?
- collapse_spaces!
- remove_trailing_space!
The 'remove_whitespace!' method is recursively walking the HTML tree (skipping <pre> tags).
If a node has any children, they will be chunked into groups of inline elements vs block elements.
For each chunks of inline elements, it will call the "collapse_space!" and "remove_trailing_space!" methods.
For each chunks of block elements, it will call "remote_whitespace!" to keep walking the HTML tree recursively.
The "is_inline?" method determines whether a node is part of a inline context.
A node is inline iif it's a text node or it's an inline tag, but not <br>, and all its children are also inline.
The "collapse_spaces!" method will collapse any kind of (white) space into a single space (" ") character, even accros tags.
For example, if we have " Foo \n<i> Bar </i>\t42", it will return "Foo <i>Bar </i>42".
Finally, the "remove_trailing_space!" method is there to remove any trailing space that might creep in at the end of the inline chunk.
This solution is not 100% bullet-proof.
It does not support RTL languages at all and has some caveats that I felt were not worth the work to get properly fixed.
FIX: better detection of hidden elements when converting HTML to Markdown

DEV: remove unused 'sanitize' gem
Wow, did you just read all that?! Congratz, here's a cookie: 🍪.
We have the `# frozen_string_literal: true` comment on all our

to call #freeze on any literals.
For files with `# frozen_string_literal: true`
```
puts %w{a b}[0].frozen?
=> true
puts "hi".frozen?

Trigger an event for plugins to consume when a user session is refreshed.
This allows external auth to be notified about account activity, and be
able to take action such as use oauth refresh tokens to keep oauth
tokens valid.
If the feature is enabled, staff members can construct a URL and publish a
topic for others to browse without the regular Discourse chrome.
This is useful if you want to use Discourse like a CMS and publish
topics as articles, which can then be embedded into other systems.
* DEPRECATION: Remove support for api creds in query params
This commit removes support for api credentials in query params except
for a few whitelisted routes like rss/json feeds and the handle_mail
route.
Several tests were written to valid these changes, but the bulk of the
spec changes are just switching them over to use header based auth so
that they will pass without changing what they were actually testing.
Original commit that notified admins this change was coming was created
over 3 months ago: 2db2003187
* fix tests
* Also allow iCalendar feeds

* FIX: guardian always got user but sometimes it is anonymous
```
def initialize(user = nil, request = nil)
@user = user.presence || AnonymousUser.new
@request = request
end
```
AnonymouseUser defines `blank?` method
```
class AnonymousUser
def blank?
true
end
...
end
```
so if we would use @user.present? it would be correct, however, just @user is always true
* FEATURE: add setting `auto_approve_email_domains` to auto approve users
This commit adds a new site setting `auto_approve_email_domains` to
auto approve users based on their email address domain.
Note that if a domain already exists in `email_domains_whitelist` then
`auto_approve_email_domains` needs to be duplicated there as well,
since users won’t be able to register with email address that is
not allowed in `email_domains_whitelist`.
* Update config/locales/server.en.yml

* FIX: Perform crop using user-specified image sizes
It used to resize the images to max width and height first and then
perform the crop operation. This is wrong because it ignored the user
specified image sizes from the Markdown.
* DEV: Use real images in test
Previously we would consider a user "present" and "last seen" if the
browser window was visible.
This has many edge cases, you could be considered present and around for
days just by having a window open and no screensaver on.
Instead we now also check that you either clicked, transitioned around app
or scrolled the page in the last minute in combination with window
visibility
This will lead to more reliable notifications via email and reduce load of
message bus for cases where a user walks away from the terminal
Previous to this change slugs for leaves in 3 level nestings would not work
Our UX picks only the last two levels
This also makes the results consistent for slugs as it enforces order.
- Define the CSP based on the requested domain / scheme (respecting force_https)
- Update EnforceHostname middleware to allow secondary domains, add specs
- Add URL scheme to anon cache key so that CSP headers are cached correctly
New `duration` attribute is introduced for the `set_or_create_timer` method in the commit aad12822b7 for "based on last post" and "auto delete replies" topic timers.
Two behaviors in the mail gem collide:
1. Attachments are added as extra parts at the top level,
2. When there are both text and html parts, the content type is set to
'multipart/alternative'.
Since attachments aren't alternative renderings, for emails that contain
attachments and both html and text parts, some coercing is necessary.
* This PR implements the scheduling and notification system for bookmark reminders. Every 5 minutes a schedule runs to check any reminders that need to be sent before now, limited to **300** reminders at a time. Any leftover reminders will be sent in the next run. This is to avoid having to deal with fickle sidekiq and reminders in the far-flung future, which would necessitate having a background job anyway to clean up any missing `enqueue_at` reminders.
* If a reminder is sent its `reminder_at` time is cleared and the `reminder_last_sent_at` time is filled in. Notifications are only user-level notifications for now.
* All JavaScript and frontend code related to displaying the bookmark reminder notification is contained here. The reminder functionality is now re-enabled in the bookmark modal as well.
* This PR also implements the "Remind me next time I am at my desktop" bookmark reminder functionality. When the user is on a mobile device they are able to select this option. When they choose this option we set a key in Redis saying they have a pending at desktop reminder. The next time they change devices we check if the new device is desktop, and if it is we send reminders using a DistributedMutex. There is also a job to ensure consistency of these reminders in Redis (in case Redis drops the ball) and the at desktop reminders expire after 20 days.
* Also in this PR is a fix to delete all Bookmarks for a user via `UserDestroyer`
There are three modifiers:
- serialize_topic_excerpts (boolean)
- csp_extensions (array of strings)
- svg_icons (array of strings)
When multiple themes are active, the values will be combined. The combination method varies based on the setting. CSP/SVG arrays will be combined. serialize_topic_excerpts will use `Enumerable#any`.
PostMover passes to PostCreator a `created_at` that is a `ActiveSupport::WithTimeZone` instance (and also `is_a? Time`). Previously it was always being passed through `Time.zone.parse` so it would lose sub-second information. Now, it takes `Time` input as-is, while still parsing other types.
This is because the TOTP gem identifies as a colon as an addressable
protocol. The solution for now is to remove the colon in the issuer
name.
Changing the issuer changes the token values, but now it was completely
broken for colons so this should not be breaking anyone new.
A follow-up correction to this change https://github.com/discourse/discourse/pull/9001.
When admin changes staff email still enforce old email confirm. Only allow auto-confirm of a new email by admin IF the target user is not also an admin. If an admin gets locked out of their email the site admin can use the rails console to solve the issue in a pinch.
When admin changes a user's email from the preferences page of that user:
* The user will not be sent an email to confirm that their
email is changing. They will be sent a reset password email
so they can set the password for their account at the new
email address.
* The user will still be sent an email to their old email to inform
them that it was changed.
* Admin and staff users still need to follow the same old + new
confirm process, as do users changing their own email.
If a group mention could be notified on preview it was given an `<a>`
tag with the `.notify` class. When cooked it would display differently.
This patch makes the server side cooking match the client preview.
After adding a tag as a synonym of another tag,
both tags will have the wrong topic counts. It's
corrected within 12 hours by the EnsureDbConsistency
job. This fix ensures the topic counts are updated
much sooner.
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.

This commit removes logic about spoilers because it should live inside
of the discourse-spoiler-alert plugin.
This PR:
https://github.com/discourse/discourse-spoiler-alert/pull/38
also completely removes spoilers from excerpts in order to keep them
from leaking in topic previews and notifications.
Some auth providers (e.g. Auth0 with default configuration) send the email address in the name field. In Discourse, the name field is made public, so this commit adds a safeguard to prevent emails being made public.
For some reasons, we have two ways of associating "custom fields" to a new topic:
using 'meta_data' and 'custom_fields'.
However, if we were to provide both arguments, the 'meta_data' would be overwritten
by any 'custom_fields' provided.
This commit ensures we can use both and merges the 'custom_fields' with the 'meta_data'.
This fix ensures that the site setting `post_edit_time_limit` does not
bypass the limit of the site setting `min_trust_to_edit_post`. This
prevents a bug where users that did not meet the minimum trust level to
edit could edit the title of topics.
When we change upload's sha1 (e.g. when resizing images) it won't match the data in the most recent S3 inventory index. With this change the uploads that have been updated since the inventory has been generated are ignored.
When FinalDestination is given a URL it encodes it before doing anything else. however S3 presigned URLs should not be messed with in any way otherwise we can end up with 400 errors when downloading the URL e.g.
<Error><Code>InvalidToken</Code><Message>The provided token is malformed or otherwise invalid.</Message>
The signature of presigned URLs is very important and is automatically generated and should be preserved.
For example /t/ URLs were being replaced if they contained secure-media-uploads so if you made a topic called "Secure Media Uploads Are Cool" the View Topic link in the user notifications would be stripped out.
Refactored code so this secure URL detection happens in one place.
Previously if somehow a user created a blank markdown document using tag
tricks (eg `<p></p><p></p><p></p><p></p><p></p><p></p>`) and so on, we would
completely strip the document down to blank on post process due to onebox
hack.
Needs a followup cause I am still unclear about the reason for empty p stripping
and it can cause some unclear cases when we re-cook posts.
Basically, say you had already downloaded a certain image from a certain URL
using pull_hotlinked_images and the onebox. The upload would be stored
by its sha as an upload record. Whenever you linked to the same URL again
in a post (e.g. in our case an og:image on review.discourse) we would
would reuse the original upload record because of the sha1.
However when you turned on secure media this could cause problems as
the first post that uses that upload after secure media is enabled
will set the access control post for the upload to the new post.
Then if the post is deleted every single onebox/link to that same image
URL will fail forever with 403 as the secure-media-uploads URL fails
if the access control post has been deleted.
To fix this when cooking posts and pulling hotlinked images, we only
allow using an original upload by URL if its access control post
matches the current post, and if the original_sha1 is filled in,
meaning it was uploaded AFTER secure media was enabled. otherwise
we just redownload the media again to be safe, as the URL will always
be new then.
The new search modifier `in:all` can be used to include both public and personal messages in the same search.

* DEV: Add a fake Mutex that for concurrency testing with Fibers
* DEV: Support running in sleep order in concurrency tests
* FIX: A separate FallbackHandler should be used for each redis pair
This commit refactors the FallbackHandler and Connector:
* There were two different ways to determine whether the redis master
was up. There is now one way and it is the responsibility of the
new RedisStatus class.
* A background thread would be created whenever `verify_master` was
called unless the thread already existed. The thread would
periodically check the status of the redis master. However, checking
that a thread is `alive?` is an ineffective way of determining
whether it will continue to check the redis master in the future
since the thread may be in the process of winding down.
Now, this thread is created when the recorded master status goes from
up to down. Since this thread runs the only part of the code that is
able to bring the recorded status up again, we ensure that only one
thread is probing the redis master at a time and that there is always
a thread probing redis master when it is recorded as being down.
* Each time the status of the redis master was checked periodically, it
would spawn a new thread and immediately join on it. I assume this
happened to isolate the check from the current execution, but since
the join rethrows exceptions in the parent thread, this was not
effective.
* The logic for falling back was spread over the FallbackHandler and
the Connector. The connector is now a dumb object that delegates
responsibility for determining the status of redis to the
FallbackHandler.
* Previously, failing to connect to a master redis instance when it was
not recorded as down would raise an exception. Now, this exception is
passed to `Discourse.warn_exception` and the connection is made to
the slave.
This commit introduces the FallbackHandlers singleton:
* It is responsible for holding the set of FallbackHandlers.
* It adds callbacks to the fallback handlers for when a redis master
comes up or goes down. Main redis and message bus redis may exist on
different or the same redis hosts and so these callbacks may all
exist on the same FallbackHandler or on separate ones.
These objects are tested using fake concurrency provided by the
Concurrency module:
* An `around(:each)` hook is used to cause each test to run inside a
Scenario so that the test body, mocking cleanup and `after(:each)`
callbacks are run in a different Fiber.
* Therefore, holting the execution of the Execution abruptly (so that
the fibers aren't run to completion), prevents the mocking cleaning
and `after(:each)` callbacks from running. I have tried to prevent
this by recovering from all exceptions during an Execution.
* FIX: Create frozen copies of passed in config where possible
* FIX: extract start_reset method and remove method used by tests

Add TopicUploadSecurityManager to handle post moves. When a post moves around or a topic changes between categories and public/private message status the uploads connected to posts in the topic need to have their secure status updated, depending on the security context the topic now lives in.
When we were pulling hotlinked images for oneboxes in the CookedPostProcessor, we were using the direct S3 URL, which returned a 403 error and thus did not set widths and heights of the images. We now cook the URL first based on whether the upload is secure before handing off to FastImage.
Let's say post #2 quotes post number #1. If a user decides to quote the
quote in post #2, it should keep the information of post #1
("user_1, post: 1, topic: X"), instead of replacing with current post
info ("user_2, post: 2, topic: X").
* enqueue spam/dmarc failing emails instead of hiding
* add translations for dmarc/spam enqueued reasons
* unescape quote
* if email_in_authserv_id is blank return gray for all emails
### 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.
This ensures that the user object is created fresh for each example.
This is required for this particular spec as we can not risk having a stale
object, which can lead to a flaky spec.
People rarely want to have their avatars show up as the preview image on social media platforms. Instead, we should fall back to the site opengraph image.
It used to check how many quotes were inside a post, without taking
considering that some quotes can contain other quotes. This commit
selects only top level quotes.
I had to use XPath because I could not find an equivalent CSS
selector.
Meta thread: https://meta.discourse.org/t/sending-a-pm-with-the-following-title-causes-an-error/135654/3
We had an issue where if someone sent a PM with crazy
characters that are stripped and we end up with only
a number, the topic redirect errored because the slug was
a number. so instead we return the default as well if
the slug is a number after prettification
The ROTP gem is only used in a very small amount of places in the app, we don't need to globally require it.
Also set the Addressable gem to not have a specific version range, as it has not been a problem yet.
Some slight refactoring of UserSecondFactor here too to use SecondFactorManager to avoid code repetition
This is a slight workaround which helps somewhat now but is pending a larger
fix.
When this spec ran in parallel mode uploads could start cross talking and
an upload you expect to be there may vanish.
This works around the issue by making the upload unique every time it is
created
It also folds up an expensive test into the main one.
* DEV: Add API to alter uploads Markdown
* DEV: Extract data attributes from image / download Markdown
For example '[test|attachment|hello=world]' will generate an 'a' element
with a data attribute: 'data-hello=world'.
This commit also makes MarkdownIt to transform '|attachment' into
'class="attachment"'. This transformation used to be a part of the
process which resolves short URLs (i.e. upload://).
* DEV: Export imageNameFromFileName
Non UTF-8 user_agent requests were bypassing logging due to PG always
wanting UTF-8 strings.
This adds some conversion to ensure we are always dealing with UTF-8
This fixes the following issues:
* The link element on the lightbox which pops open the lightbox was linking to the S3 URL with a private ACL instead of the secure media URL for the image
* Change to use `@post.with_secure_media?` in `CookedPostProcessor` for URL cooking, as in some cases, like when a post is edited and an upload is added, `upload.secure?` can be false which resulted in `srcset` URLs not being cooked correctly to secure media upload urls.
This feature adds the ability to define synonyms for tags, and the ability to merge one tag into another while keeping it as a synonym. For example, tags named "js" and "java-script" can be synonyms of "javascript". When searching and creating topics using synonyms, they will be mapped to the base tag.
Along with this change is a new UI found on each tag's page (for example, `/tags/javascript`) where more information about the tag can be shown. It will list the synonyms, which categories it's restricted to (if any), and which tag groups it belongs to (if tag group names are public on the `/tags` page by enabling the "tags listed by group" setting). Staff users will be able to manage tags in this UI, merge tags, and add/remove synonyms.
This bug was causing some unusual behavior when the last post is filtered (e.g. from an ignored user). In some situations this would cause suggested topics to be omitted from the payload.
The next_page specs have been updated to remove most of the stubs
* 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
We already cache failed onebox URL requests client-side, we now want to cache this on the server-side for extra protection. failed onebox previews will be cached for 1 hour, and any more requests for that URL will fail with a 404 status. Forcing a rebake via the Rebake HTML action will delete the failed URL cache (like how the oneboxer preview cache is deleted).
If a user has more than 60 active sessions, the oldest sessions will be terminated automatically. This protects performance when logging in and when loading the list of recently used devices.
This is a bottom up rewrite of Discourse cache to support faster performance
and a limited surface area.
ActiveSupport::Cache::Store accepts many options we do not use, this partial
implementation only picks the bits out that we do use and want to support.
Additionally params are named which avoids typos such as "expires_at" vs "expires_in"
This also moves a few spots in Discourse to use Discourse.cache over setex
Performance of setex and Discourse.cache.write is similar.
Discourse.cache is a more consistent method to use and offers clean fallback
if you are skipping redis
This is part of a larger change that both optimizes Discoruse.cache and omits
use of setex on $redis in favor of consistently using discourse cache
Bench does reveal that use of Rails.cache and Discourse.cache is 1.25x slower
than redis.setex / get so a re-implementation will follow prior to porting
PG 12 changes internals in a subtle way, time jitter is noticed in a few new
spots (which is normal) and default ordering is a bit different which is meant
to be random anyway.
There was an issue on dev where when uploading secure media, the href of the media was correctly being replaced in the CookedPostProcessor, but the srcset urls were not being replaced correctly. This is because UrlHelper.cook_url was returning the asset host URL for the media for secure media instead of returning early with the proxied secure proxy url.
In non-login-required sites, we prevent secure uploads already used in PMs from being used in public topics.
In login_required sites, secure uploads should be reusable in any topic, PM or not.
Previously our custom exception handler was unable to handle situations
where an invalid mime type was sent, resulting in a warning log
This ensures we pretend a request is HTML for the purpose of rendering
the error page if an invalid mime type from a scanner is shipped to the app
* Fix an issue where if an edit was made to a post with a reason provided, and then another edit was made with no reason, the original edit reason got wiped out
* We now always make a post revision (even with ninja edits) if an edit reason has been provided and it is different from the current edit reason

This PR introduces a new secure media setting. When enabled, it prevent unathorized access to media uploads (files of type image, video and audio). When the `login_required` setting is enabled, then all media uploads will be protected from unauthorized (anonymous) access. When `login_required`is disabled, only media in private messages will be protected from unauthorized access.
A few notes:
- the `prevent_anons_from_downloading_files` setting no longer applies to audio and video uploads
- the `secure_media` setting can only be enabled if S3 uploads are already enabled and configured
- upload records have a new column, `secure`, which is a boolean `true/false` of the upload's secure status
- when creating a public post with an upload that has already been uploaded and is marked as secure, the post creator will raise an error
- when enabling or disabling the setting on a site with existing uploads, the rake task `uploads:ensure_correct_acl` should be used to update all uploads' secure status and their ACL on S3
Previously people were not consistent about mocking which left internals in
a fragile state when running subfolder specs.
This introduces a simple helper `set_subfolder` which you can use to set
the subfolder for the spec. It takes care of proper configuration of subfolder
and teardown.
```
# usage
set_subfolder "/my_amazing_subfolder"
```
You should no longer stub base_uri or global_settings
This version hash is used for the filename, and so browsers/CDNs cache based on it. Previously the version hash was based only on the list of requested icons. This can cause issues in a couple of situations, most commonly when developing themes with custom icons:
- A requested icon does not exist, and then later is added to the theme. The bundle output changes, but the hash did not
- The SVG content of an icon changes, but the name of the icon does not. The bundle output changes, but the hash did not
* When viewing a tag, the search widget will now show a checkbox to scope the search by tag, which will limit search results to that tag on desktop and mobile
This method had grown into a monster. Its query had bugs
that I couldn't fix, and new features would be hard to add.
Also I don't understand how it all works anymore...
Replace it with common table expressions that can be queried
to generate the results we need, instead of subtracting
results using lots of "NOT IN" clauses.
Fixed are bugs with tag schemas that use combinations of
tag groups, parent tags, and one-tag-per-topic restrictions.
For example: https://meta.discourse.org/t/130991/6
Previously we were always hard-coding expiry, this allows the secure session
to correctly handle custom expiry times
Also adds a ttl method for looking up time to live
Instead of enabling `suppress_from_latest` setting on many categories now we can enable `mute_all_categories_by_default` site setting. Then users should opt-in to categories for them to appear in the latest and categories pages.
This makes it easy to run multiple commands with the same keyword arguments. The main use is for using `chdir` across multiple commands. The `Dir.chdir` method is not concurrency safe because it switches the working directory of the entire process.
- Allow revoking keys without deleting them
- Auto-revoke keys after a period of no use (default 6 months)
- Allow multiple keys per user
- Allow attaching a description to each key, for easier auditing
- Log changes to keys in the staff action log
- Move all key management to one place, and improve the UI
This is a follow-up to the new feature that allows a category to
require a certain number of tags from a tag group. The tag input will
shows results from the required group if none have been chosen yet.
Once a require tag is selected, the tag input will include other
results as usual. Staff users can ignore this restriction, so the input
behaviour is unchanged for them.
* use image alt as a fallback when there's no title
* update spec
we used to check that the overlay information is added when the image has a titie. This adds 2 more scenarios. One where an image has both a title and an alt, in which case the title should be used and alt ignored.
The other is when there's only an alt, it should then be used to generate the overlay
Meta thread: https://meta.discourse.org/t/cant-dismiss-unread-if-last-post-is-an-assign-or-whisper/131823/7
* when sending a whisper, the highest_staff_post_number is set
in the next_post_number method for a Topic, but the
highest_post_number is left alone. this leaves a situation
where highest_staff_post_number is > highest_post_number
* when TopicsBulkAction#dismiss_posts was run, it was only setting the topic_user
highest_seen_post_number using the highest_post_number from the topic, so if
the user was staff and the last post in a topic was a whisper
their highest seen number was not set, and the topic stayed unread
Found through testing that the bug wasn't to do with Assign/Unassign as they do not affect the post numbers, only whispering does.
In a category's settings, the Tags tab has two new fields to
specify the number of tags that must be added to a topic
from a tag group. When creating a new topic, an error will be
shown to the user if the requirement isn't met.
This was not causing any known issue, because the system user ID is always the same across all sites. However, we should cache this on a per-site basis to be safe.
This ensures we only update last_posted_at which is user facing for non messages
and non whispers.
We still update this date for secure categories, we do not revert it for
deleted posts.
Adds the settings:
raw_email_max_length, raw_rejected_email_max_length, delete_rejected_email_after_days.
These settings control retention of the "raw" emails logs.
raw_email_max_length ensures that if we get incoming email that is huge we will truncate it removing uploads from the raw log.
raw_rejected_email_max_length introduces an even more aggressive truncation for rejected incoming mail.
delete_rejected_email_after_days controls how many days we will keep rejected emails for (default 90)
* FEATURE: Site setting/ui to allow users to set their primary group
* prettier and remove logic from account template
* added 1 to 43 to make web_hook_user_serializer_spec pass
While editing the first post it does't bumped the topic when the new post revision created. Because we wrongly assumed that the hidden tags are changed even when no tags are updated.
Doing .pluck(:column).first is a very common pattern in Discourse and in
most cases, a limit cause isn't being added. Instead of adding a limit
clause to all these callsites, this commit adds two new methods to
ActiveRecord::Relation:
pluck_first, equivalent to limit(1).pluck(*columns).first
and pluck_first! which, like other finder methods, raises an exception
when no record is found
Trying to truncate encoded slugs will mean that we have to keep the URL
valid, which can be tricky as you have to be aware of multibyte
characters.
Since we already have upper bounds for the title, the slug won't grow
for more than title*6 in the worst case. The slug column in the topic
table can store that just fine.
Added a test to ensure that a generated slug is a valid URL too, so we
don't introduce regressions in the future.
Previously the 'local_cdn_url' method didn't returned the correct cdn url. So we written few incorrect spec tests too.\n\nf92a6f7ac5228342177bf089d269e2f69a69e2f5
When an admin changes the site setting slug_generation_method to
encoded, we weren't really encoding the slug, but just allowing non-ascii
characters in the slug (unicode).
That brings problems when a user posts a link to topic without the slug, as
our topic controller tries to redirect the user to the correct URL that contains
the slug with unicode characters. Having unicode in the Location header in a
response is a RFC violation and some browsers end up in a redirection loop.
Bug report: https://meta.discourse.org/t/-/125371?u=falco
This commit also checks if a site uses encoded slugs and clear all saved slugs
in the db so they can be regenerated using an onceoff job.
Using popups is becoming increasingly rare. Full page redirects are already used on mobile, and for some providers. This commit removes all logic related to popup authentication, leaving only the full page redirect method.
For more info, see https://meta.discourse.org/t/do-we-need-popups-for-login/127988
* 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.
This means that TL0 users can message groups with "Who can message this
group?" set to "Everyone".
It also means that members of a group with "Who can message this
group?" set to "members, moderators and admins" can also message the
group, even when their trust level is below min_trust_to_send_messages.
* Adjustments to pass specs on Rails 6.0.0
* Use classic autoloader instead of Zeitwerk
* Update Rails 6.0.0 deprecated methods
* Rails 6.0.0 not allowing column with integer name
* Drop freedom_patches/rails6.rb
* Default value for trigger_transactional_callbacks? is true
* Bump rspec-rails version to 4.0.0.beta2
* FEATURE: Add tl2 threshold for editing new posts
* Adds a new setting and for tl2 editing posts (30 days same as old value)
* Sets the tl0/tl1 editing period as 1 day
* FIX: Spec uses wrong setting
* Fix site setting on guardian spec
* FIX: post editing period specs
* Avoid shared examples
* Use update_columns to avoid callbacks on user during tests
This commit introduces 2 features:
1. DISCOURSE_COMPRESS_ANON_CACHE (true|false, default false): this allows
you to optionally compress the anon cache body entries in Redis, can be
useful for high load sites with Redis that lives on a separate server to
to webs
2. DISCOURSE_ANON_CACHE_STORE_THRESHOLD (default 2), only pop entries into
redis if we observe them more than N times. This avoids situations where
a crawler can walk a big pile of topics and store them all in Redis never
to be used. Our default anon cache time for topics is only 60 seconds. Anon
cache is in place to avoid the "slashdot" effect where a single topic is
hit by 100s of people in one minute.
Start tracking the date an api key was last used. This has already been
the case for user_api_keys.
This information can provide us with the ability to automatically expire
unused api keys after N days.
This allows custom plugins such as prometheus exporter to log how many
requests are stored in the anon cache vs used by the anon cache.
This metric allows us to fine tune cache behaviors
* Revert "Revert "FEATURE: Publish read state on group messages. (#7989) [Undo revert] (#8024)""
This reverts commit 36425eb9f0.
* Fix: Show who read only if the attribute is enabled
* PERF: Precalculate the last post readed by a group member
* Use book-reader icon instear of far-eye
* FIX: update topic groups correctly
* DEV: Tidy up read indicator update on write
This is a very long standing bug we had, if a plugin attempted to amend a
serializer core was not "correcting" the situation for all descendant classes
this often only showed up in production cause production eager loads serializers
prior to plugins amending them.
This is a critical fix for various plugins
* Reenable: "FEATURE: Publish read state on group messages. (#7989)"
This reverts commit 67f5cc1ce8.
* FIX: Read indicator only appears when the group setting is enabled
* Enable or disable read state based on group attribute
* When read state needs to be published, the minimum unread count is calculated in the topic query. This way, we can know if someone reads the last post
* The option can be enabled/disabled from the UI
* The read indicator will live-updated using message bus
* Show read indicator on every post
* The read indicator now shows read count and can be expanded to see user avatars
* Read count gets updated everytime someone reads a message
* Simplify topic-list read indicator logic
* Unsubscribe from message bus on willDestroyElement, removed unnecesarry values from post-menu, and added a comment to explain where does minimum_unread_count comes from
There are 5 visibility levels (similar to group visibility)
public (default)
logged-in users
members only
staff
owners
Admins & group owners always have visibility to group members.
When a user liked, unliked and liked again the same post, the poster
would receive a notification such as "X and X liked ...". This happened
because PostActionNotifier.post_action_created was called twice.
All posts created by the user are counted unless they are deleted,
belong to a PM sent between a non-human user and the user or belong
to a PM created by the user which doesn't have any other recipients.
It also makes the guardian prevent self-deletes when SSO is enabled.
- Client-side censoring fixed for non-chrome browsers. (Regular expression rewritten to avoid lookback)
- Regex generation is now done on the server, to reduce repeated logic, and make it easier to extend in plugins
- Censor tests are moved to ruby, to ensure everything works end-to-end
- If "watched words regular expressions" is enabled, warn the admin when the generated regex is invalid
This feature is off by default and can can be configured with the `email_total_attachment_size_limit_kb` site setting.

* FEATURE: Add search operator to see all direct messages from a user
* Only show message if related messages >= 5
* Make "all messages" the hyperlink
* Review
If a post arrives via email but must be reviewed, we now show an
icon that can be clicked to view the raw contents of the email.
This is useful if Discourse's email parser is acting odd and the user
reviewing the post wants to know what the original contents were before
approving/rejecting the post.
* 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
Context: https://meta.discourse.org/t/121589
This new setting option lets group owners message/mention large groups
without granting that privilege to all members.
Groups can now be marked as visible to "logged on users". All automatic groups (except `everyone`) are now visible to "logged on users", previously they were marked as public but suppressed in the group page for non-staff.
If a database exception is raised ActiveRecord will always rollback
even if caught.
Instead we build the query in manual SQL and DO NOTHING when there's a
conflict. If we detect nothing was done, perform an update.
The behaviour of #TERM in search has been amended
1. We try category or subcategory slugs
2. We try tags
3. We try tag-groups
The term `hello #my-group` will search for all posts tagged with any of
the tags in the tag group `My Group`
Future work may be introducing a slug cache here or caching it in the table
but the assumption is that the number of tag groups will not be huge
Adds a second factor landing page that centralizes a user's second factor configuration.
This contains both TOTP and Backup, and also allows multiple TOTP tokens to be registered and organized by a name. Access to this page is authenticated via password, and cached for 30 minutes via a secure session.
This can cause unbound CPU usage in some cases, and excessive logging in other cases. This commit moves redis readonly information into the local process, but maintains the DistributedCache for postgres readonly state.
* Support private uploads in S3
* Use localStore for local avatars
* Add job to update private upload ACL on S3
* Test multisite paths
* update ACL for private uploads in migrate_to_s3 task
This adds support for DISCOURSE_ENABLE_PERFORMANCE_HTTP_HEADERS
when set to `true` this will turn on performance related headers
```text
X-Redis-Calls: 10 # number of redis calls
X-Redis-Time: 1.02 # redis time in seconds
X-Sql-Commands: 102 # number of SQL commands
X-Sql-Time: 1.02 # duration in SQL in seconds
X-Queue-Time: 1.01 # time the request sat in queue (depends on NGINX)
```
To get queue time NGINX must provide: HTTP_X_REQUEST_START
We do not recommend you enable this without thinking, it exposes information
about what your page is doing, usually you would only enable this if you
intend to strip off the headers further down the stream in a proxy
Previously as soon as any override was defined we would regress to the slow
path for locale lookups. Additionally if `raise: true` was specified which
rails likes to add in views we would bypass the cache
The new design manages to use the fast path for many more cases
SSO uses a special param to username suggester that whitelists a username
due to previous work we amended our lookup logic and started ignoring this
whitelist.
The fix ensures we always respect it, and also improves on the original
implementation that forgot to normalize the username.
This also corrects FileHelper.download so it supports "follow_redirect"
correctly (it used to always follow 1 redirect) and adds a `validate_url`
param that will bypass all uri validation if set to false (default is true)
Net::HTTP always returns ASCII-8BIT encoding. File.read auto-detects the encoding. This leads to an encoding inconsistency between a fresh download, and a cached download. This commit ensures all downloaded files are treated equally, by always returning the cached version from the filesystem, even during initial download.
One symptom of this problem is during theme exports: https://meta.discourse.org/t/116907
Related ruby ticket: https://bugs.ruby-lang.org/issues/2567
Previously username suggester would give up after 100 attempts at getting
a username and fallback to random string.
This amends the logic so we do all the work of figuring out a good username
in SQL and avoids a large amount of queries in cases where a lot of usernames
were used up.
This corrects an issue on sites with large numbers of anon users
Use the cooked version of the post and the quote to compare their content in
order to take into account the "typographer" option of the markdown pipeline.
We were blocking user registrations with same username and password,
but allowing usernames to be changed to be same as password later.
Also disallow names to be the same as password.
* English shouldn't fallback to any other locale
* Calculate fallback for default locale if it isn't English (useful for en_US)
* Reuse the fallback locale list when outputting translations to JavaScript
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
The instagram onebox sometimes surrounds the image with an `<a>` tag, which was breaking the aspect ratio logic, and therefore causing posts to change height on load.
Since 5bfe051e, Discourse user agents are marked as non-crawlers (to avoid accidental blacklisting). This makes sure pageviews for these agents are tracked as crawler hits.
We found score hard to understand. It is still there behind the scenes
for sorting purposes, but it is no longer shown.
You can now filter by minimum priority (low, med, high) instead of
score.
* 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 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 shows a notification number besides the flag icon in the
post menu if there is reviewable content associated with the post.
Additionally, if there is pending stuff to review, the icon has a red
background.
We have also removed the list of links below a post with the flag
status. A reviewer is meant to click the number beside the flag icon to
view the flags. As a consequence of losing those links, we've removed
the ability to undo or ignore flags below a post.
Minor fixes to add Rails 6 support to Discourse, we now will boot
with RAILS_MASTER=1, all specs pass
Only one tiny deprecation left
Largest change was the way ActiveModel:Errors changed interface a
bit but there is a simple backwards compat way of working it
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
We had quite a few cases in core where inputs are being mutated as a side
effect of calling a method.
This handles all the cases where specs caught this.
Mutating inputs makes code harder to reason about. Eg:
```
frog = "frog"
jump(frog)
puts frog
"fly" # ?????
```
This commit is part of a followup commit that adds # frozen_string_literal
to all our specs.
Previous behaviour was to silently remove tags that
belonged to a group with a parent tag that was missing.
The "required parent tag" feature is meant to guide people
to use the correct tags and show scoped results in the tag
input field, and to help create topic lists of related
tags. It isn't meant to be a strict requirement in the
composer that should trigger errors or restrictions.
* DEV: Replace site_setting_saved DiscourseEvent with site_setting_changed
site_setting_saved is confusing for a few reasons:
- It is attached to the after_save of the ActiveRecord model. This is confusing because it only works 'properly' with the db_provider
- It passes the activerecord model as a parameter, which is confusing because you get access to the 'database' version of the setting, rather than the ruby setting. For example, booleans appear as 'y' or 'n' strings.
- When the event is called, the local process cache has not yet been updated. So if you call SiteSetting.setting_name inside the event handler, you will receive the old site setting value
I have deprecated that event, and added a new site_setting_changed event. It passes three parameters:
- Setting name (symbol)
- Old value (in ruby format)
- New value (in ruby format)
It is triggered after the setting has been persisted, and the local process cache has been updated.
This commit also includes a test case which describes the confusing behavior. This can be removed once site_setting_saved is removed.
If you turn it on now, default all users to approved since they were
previously. Also support approving a user that doesn't have a reviewable
record (it will be created first.)
This also includes a refactor to move class method calls to
`DiscourseEvent` into an initializer. Otherwise the load order of
classes makes a difference in the test environment and some settings
might be triggered and others not, randomly.
This new site setting determines the maximum age of unread topics in
suggested. By default if you have any unread topics older than 90 days
they will be omitted from suggested.
This change was added for 2 reasons:
1. A performance safeguard, some users tend to collect a huge amount of
read state so it becomes super expensive to find unread
2. People who collect a large amount of unread are much more interested in
recent unread topics vs ancient unread topics, this makes suggested more
relevant
Also, this is a minor speed up for tests cause 3 expensive tests became 1.
Theme developers can include any number of scss files within the /scss/ directory of a theme. These can then be imported from the main common/desktop/mobile scss.
* FIX: correctly retrieve 'login required' setting value on wizard
FEATURE: extract 'invite only' setting in a separate checkbox control
* Update invite_only checkbox locale on wizard.

Previously jobs would fail silently in test mode. Now they will raise the exception and cause the relevant test to fail. This identified a few broken tests, which I will fix in a followup commit
This functionality was never supported but before the new review queue
it didn't have any errors. Now the combination of settings is prevented
and existing sites with sso enabled will be migrated to remove invite
only.
The default ranking options ranks by the number of matches which is
highly problematic when posts are stuffed with a keyword. The ranking
will now be divided by the document length which is a much fairer way to
rank.
Includes support for flags, reviewable users and queued posts, with REST API
backwards compatibility.

Previously we would bypass touching `Topic.updated_at` for whispers and post
recovery / deletions.
This meant that certain types of caching can not be done where we rely on
this information for cache accuracy.
For example if we know we have zero unread topics as of yesterday and whisper
is made I need to bump this date so the cache remains accurate
This is only half of a larger change but provides the groundwork.
Confirmed none of our serializers leak out Topic.updated_at so this is safe
spot for this info
At the moment edits still do not change this but it is not relevant for the
unread cache.
This commit also cleans up some specs to use the new `eq_time` matcher for
millisecond fidelity comparison of times
Previously `freeze_time` would fudge this which is not that clean.
- The test_email job is removed, because it was always being run synchronously (not in sidekiq)
- 34b29f62 added a bypass for critical emails, to match the spec. This removes the bypass, and removes the spec.
- This adapts the specs for 72ffabf6, so that they check for emails being sent
- This reimplements c2797921, allowing test emails to be sent even when emails are disabled
* improved emoji support
- always optimize images as part of the task
- use the unicode standard ordering/naming for sections
* UX: more height for when there are recently used
Migrates email user options to a new data structure, where `email_always`, `email_direct` and `email_private_messages` are replace by
* `email_messages_level`, with options: `always`, `only_when_away` and `never` (defaults to `always`)
* `email_level`, with options: `always`, `only_when_away` and `never` (defaults to `only_when_away`)
* First take
* Add support for sprites in themes
Automatically register any custom icons added via themes or plugins
* Fix theme sprite caching
* Simplify test
* Update lib/svg_sprite/svg_sprite.rb

* Fix /svg-sprite/search request
It is not a setting, and only relevant in specs. The new API is:
```
Jobs.run_later! # jobs will be thrown on the queue
Jobs.run_immediately! # jobs will run right away, avoid the queue
```
If the existing email address for a user ends in `.invalid`, we should take the email address from an authentication payload, and replace the invalid address. This typically happens when we import users from a system without email addresses.
This commit also adds some extensibility so that plugin authenticators can define `always_update_user_email?`
When using the api and you provide an http header based api key any other
auth based information (username, external_id, or user_id) passed in as
query params will not be used and vice versa.

Previously if you wanted to have jobs execute in test mode, you'd have
to do `SiteSetting.queue_jobs = false`, because the opposite of queue
is to execute.
I found this very confusing, so I created a test helper called
`run_jobs_synchronously!` which is much more clear about what it does.
- Notices are visible only by poster and trust level 2+ users.
- Notices are not generated for non-human or staged users.
- Notices are deleted when post is deleted.
Now you can also make authenticated API requests by passing the
`api_key` and `api_username` in the HTTP header instead of query params.
The new header values are: `Api-key` and `Api-Username`.
Here is an example in cURL:
``` text
curl -i -sS -X POST "http://127.0.0.1:3000/categories" \
-H "Content-Type: multipart/form-data;" \
-H "Api-Key: 7aa202bec1ff70563bc0a3d102feac0a7dd2af96b5b772a9feaf27485f9d31a2" \
-H "Api-Username: system" \
-F "name=7c1c0ed93583cba7124b745d1bd56b32" \
-F "color=49d9e9" \
-F "text_color=f0fcfd"
```
There is also support for `Api-User-Id` and `Api-User-External-Id`
instead of specifying the username along with the key.
If you reply to an email with the word "mute" a topic will be muted
If you reply to an email with the word "track" a topic will be tracked
If you reply to an email with the word "watch" a topic will be watched

This is a common pattern we see in tests. The `id` of the upload
is used to create the URL and we assume the `id` will always be
in a certain range which depends on the database.
Uses github.com/discourse/moment-timezone-names-translations to translate timezone names.
Plugins can also provide their own timezone name translations.
Previously with had `in:title` and `in:first` search shortcuts for
searching in first post or title only. They are a bit of handful to type.
This add 2 shortcuts (t and f) for searching titles of first posts.
This commit also cleans up all advanced filters, they were not properly
regex terminated allowing for weird clauses like `in:firstinator` acting
the same as `in:first`
When the S3 store was enabled, we were only applying the S3 CDN.
So all images stored locally, like the emojis, were never put on the local CDN.
Fixed a bunch of CookedPostProcessor test by adding a call to 'optimize_urls'
in order to get final URLs.
I also removed the unnecessary PrettyText.add_s3_cdn method since this is already
handled in the CookedPostProcessor.
It was getting caught in a `DistributedMutex` deadlock (twice!), which
meant this test was taking 120s to run.
I'm not sure why queue jobs was turned off here, because when I turn it
on the test passes and takes <2s instead.
This does not serve any technical purpose. It is there to provide a signpost for any user/developer that wants to know what to do with a theme archive.
New `about.json` fields (all optional):
- `authors`: An arbitrary string describing the theme authors
- `theme_version`: An arbitrary string describing the theme version
- `minimum_discourse_version`: Theme will be auto-disabled for lower versions. Must be a valid version descriptor.
- `maximum_discourse_version`: Theme will be auto-disabled for lower versions. Must be a valid version descriptor.
A localized description for a theme can be provided in the language files under the `theme_metadata.description` key
The admin UI has been re-arranged to display this new information, and give more prominence to the remote theme options.
* FIX: allow sending PMs to staff via flag even when PMs are disabled

The `posts` relation on `Topic` is not ordered. Using `Topic.posts.first`
is basically the same as asking for a random post, it will depend on DB
order. This breaks on Topic merge and split for example.
Additionally, a huge problem with that is that it forces active record down
a slow path. `Topic.posts.first` is extremely slow on giant topics, since
it has no default ordering it appears AR materializes the entire set prior
to doing `first`.
This commit also illustrates the importance of testing, initially I only
fixed the second instance of the problem in `post_validator.rb` but testing
revealed that the problem was repeated at the top of the file.
Longer term we should consider a larger change of default ordering the posts
relations so people do not fall down this trap anymore.
We use the `id` of the upload to calculate a `depth` partition in the
filename. This test would fail if your database had a higher seed
because the depth it was looking for was hard coded to 1.
The solution was to not save the records (which is faster anyway) and
specify the `id` of the upload to make the hash deterministic.
SiteSettingExtension triggers message bus which re-establishes a
DB connection in `SiteSettingExtension#process_message`. That happens
concurrently and a test that requires a connection to the db will
fail when the reconnection is happening.
Before this patch, a high trust level user could flag something
and have an action be taken, as well as skipping the flag queue.
Now, if a TL3/TL4 cause an action, the flag will skip the minimum
visibility check and allow staff to review it.
This allows fidelity in controlling excerpt (text that shows up when you pin a topic or link to it externally):
```
I am some text
[excerpt]
This is some **custom** markdown that should be the excerpt
[/excerpt]
More text
```
Previous solution relied on DIVs, unfortunately DIVs do not play well,
by design with mixing markdown unless you have a preceding newline eg:
```
<div class='hello'>
this will be treated properly as markdown
</div>
```
This extra newline is not desirable.
I am also considering adding
```
[div class=excerpt]
[/div]
```
This would offer lots of flexibility to themes and plugins that do not want the extra annoying newline.
As per the documentation for KEYS
```
Warning: consider KEYS as a command that should only be used in production environments with extreme care. It may ruin performance when it is executed against large databases. This command is intended for debugging and special operations, such as changing your keyspace layout.
```
Instead SCAN
```
Since these commands allow for incremental iteration, returning only a small number of elements per call, they can be used in production without the downside of commands like KEYS or SMEMBERS that may block the server for a long time (even several seconds) when called against big collections of keys or elements.
```
This generates a 10x10 PNG thumbnail for each lightboxed image.
If Image Lazy Loading is enabled (IntersectionObserver API) then
we'll load the low res version when offscreen. As the image scrolls
in we'll swap it for the high res version.
We use a WeakMap to track the old image attributes. It's much less
memory than storing them as `data-*` attributes and swapping them
back and forth all the time.
`SiteSerializer#is_readonly` is cached for an anonymous user so we have
to clear the cache when disabling readonly mode. Otherwise, the site may
appear to be in readonly mode for an extended period of time.
Historically due to https://meta.discourse.org/t/why-is-discourse-so-slow-on-android/8823
we decreased page sizes of both home page and topic page on android by half.
This was done on the server side and as a side effect and caused page sizes on android
to mismatch between Android and non Android.
Unfortunately about a year ago googlebot started pretending it is Android,
this cause Google to start indexing pages as what android would see. So
it saw double the amount of pages in the index as what exists on desktop.
This in turn caused double the amount of indexing work and a large amount
of broken links on long topics.
This fix removes all special behavior which is no longer needed due to
other performance work in Discourse including raw handlebars on home page
and virtual dom on topic pages.
I tested we do not need this on Blu Advance 5.0 it has 1.3 GHZ mediatec mt6580
This phone retails for around $50 USD.
If we decide long term that we want any hacks like this we will shift them
to the client side. It can just hold data in memory without rendering.
Some URLs in browsers are non compliant and contain twos `#` this commit adds
special handling for this edge case by auto encoding any fragments containing `#`
Previously users could control excerpt with `<span class='excerpt'>`
in Markdown, this is somewhat limited for plugins that need to define this
across a section. This adds support for DIV as well
Also added some helpful functionality for plugin developers:
- Raises RuntimeException if the auth provider has been registered too late
- Logs use of deprecated parameters
* 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
Changes to functionality
- Removed syncing of user metadata including gender, location etc.
These are no longer available to standard Facebook applications.
- Removed the remote 'revoke' functionality. No other providers have
it, and it does not appear to be standard practice in other apps.
- The 'facebook_no_email' event is no longer logged. The system can
cope fine with a missing email address.
Data is migrated to the new user_associated_accounts table.
facebook_user_infos can be dropped once we are confident the data has
been migrated successfully.
A generic implementation of Auth::Authenticator which stores data in the
new UserAssociatedAccount model. This should help significantly reduce the duplicated
logic across different auth providers.
Previously, the site setting was only effective on the client side of
things. Once the site setting was been reached, all oneboxes are not
rendered. This commit changes it such that the site setting is respected
both on the client and server side. The first N oneboxes are rendered and
once the limit has been reached, subsequent oneboxes will not be
rendered.

- adds frontend ajax call that pulls icon in avatar flair preview even when it is not in subset
* Remove FA 4.7 font files
We were looking up each mention one by one without any form of caching and that results
in a problem somewhat similar to an N+1. When we have to do alot of DB
lookups, it also increased the time spent in the V8 context which may
eventually lead to a timeout. The change here makes it such that mention lookups only does a single
DB query per post that happens outside of the V8 context.
