I plan to use this in an upcoming discourse-reactions PR, where I want to like a post without notifying the user, so I can instead create a reaction notification.
Additionally, we decouple the a11y attributes from the icon itself, which will let us extend the widget's icon without losing them.
This allows authenticators to instruct the Auth::Result to override attributes without using the general site settings. This provides an easy migration path for auth plugins which offer their own "overrides email", "overrides username" or "overrides name" settings. With this new api, they can set `overrides_*` on the result object, and the attribute will be overriden regardless of the general site setting.
ManagedAuthenticator is updated to use this new API. Plugins which consume ManagedAuthenticator will instantly take advantage of this change.
The previous default aspect ratio for cropping tall images was a little
too strict and was cutting off images. This new setting should allow for
a larger range of image sizes before cropping them.
As an example, the lookup order for German was:
1. override for de
2. override for en
3. value from de
4. value from en
After this change the lookup order is the same as on the client:
1. override for de
2. value from de
3. override for en
4. value from en

If a theme name contained a double-quote, this problem could lead to invalid/unexpected HTML in the `<head>`
Note that this is not considered a security issue because themes can only be installed/named by administrators, and themes/administrators already have the ability to run arbitrary javascript.
This commit introduces a new site setting "google_oauth2_hd_groups". If enabled, group information will be fetched from Google during authentication, and stored in the Discourse database. These 'associated groups' can be connected to a Discourse group via the "Membership" tab of the group preferences UI.
The majority of the implementation is generic, so we will be able to add support to more authentication methods in the near future.

Since 3b13f1146b the email threading
in mail clients has been broken, because the random suffix meant
that the References header would always be different for non-group
SMTP email notifications sent out.
This commit fixes the issue by always using the "canonical" topic
reference ID inside the References header in the format:
topic/TOPIC_ID@HOST
Which was the old format. We also add the References header to
notifications sent for the first post arriving, so the threading
works for subsequent emails. The Message-ID header is still random
as per the previous change.
Currently we display pending posts in topics (both for author and staff
members) but the feature is only enabled when there’s an enabled global site
setting related to moderation.
This patch allows to have the same behavior for a site where there’s
nothing enabled globally but where a moderated category exists. So when
browsing a topic of a moderated category, the presence of pending posts
will be checked whereas nothing will happen in a normal category.
Currently the Message-IDs we send out for outbound email
are not unique; for a post they look like:
topic/TOPIC_ID/POST_ID@HOST
And for a topic they look like:
topic/TOPIC_ID@HOST
This commit changes the outbound Message-IDs to also have
a random suffix before the host, so the new format is
like this:
topic/TOPIC_ID/POST_ID.RANDOM_SUFFIX@HOST
Or:
topic/TOPIC_ID.RANDOM_SUFFIX@HOST
This should help with email deliverability. This change
is backwards-compatible, the old Message-ID format will
still be recognized in the mail receiver flow, so people
will still be able to reply using Message-IDs, In-Reply-To,
and References headers that have already been sent.
This commit also refactors Message-ID related logic
to a central location, and adds judicious amounts of
tests and documentation.
Under some conditions, these varied responses could lead to cache poisoning, hence the 'security' label.
Previously the Rails application would serve JSON data in place of HTML whenever Ember CLI requested an `application.html.erb`-rendered page. This commit removes that logic, and instead parses the HTML out of the standard response. This means that Rails doesn't need to customize its response for Ember CLI.
* DEV: Specify bookmarks order
It's better to order by id than to have a semi-random order. Fixes a flaky test:
```
1) TopicView with a few sample posts #bookmarks gets the first post bookmark reminder at for the user

Failure/Error: expect(first[:post_id]).to eq(bookmark1.post_id)

61
expected: 1901
62
got: 1902

* Change test
* Revert "DEV: Specify bookmarks order"
This reverts commit 1f50026231.
* REFACTOR: Improve support for consolidating notifications.
Before this commit, we didn't have a single way of consolidating notifications. For notifications like group summaries, we manually removed old ones before creating a new one. On the other hand, we used an after_create callback for likes and group membership requests, which caused unnecessary work, as we need to delete the record we created to replace it with a consolidated one.
We now have all the consolidation rules centralized in a single place: the consolidation planner class. Other parts of the app looking to create a consolidable notification can do so by calling Notification#consolidate_or_save!, instead of the default Notification#create! method.
Finally, we added two more rules: one for re-using existing group summaries and another for deleting duplicated dashboard problems PMs notifications when the user is tracking the moderator's inbox. Setting the threshold to one forces the planner to apply this rule every time.
I plan to add plugin support for adding custom rules in another PR to keep this one relatively small.
* DEV: Introduces a plugin API for consolidating notifications.
This commit removes the `Notification#filter_by_consolidation_data` scope since plugins could have to define their criteria. The Plan class now receives two blocks, one to query for an already consolidated notification, which we'll try to update, and another to query for existing ones to consolidate.
It also receives a consolidation window, which accepts an ActiveSupport::Duration object, and filter notifications created since that value.
This commit adds token_hash and scopes columns to email_tokens table.
token_hash is a replacement for the token column to avoid storing email
tokens in plaintext as it can pose a security risk. The new scope column
ensures that email tokens cannot be used to perform a different action
than the one intended.
To sum up, this commit:
* Adds token_hash and scope to email_tokens
* Reuses code that schedules critical_user_email
* Refactors EmailToken.confirm and EmailToken.atomic_confirm methods
* Periodically cleans old, unconfirmed or expired email tokens
Use @here to mention all users that were allowed to topic directly or
through group, who liked topics or read the topic. Only first 10 users
will be notified.
Allow current user to keep existent tags when adding or removing a tag.
For example, a user could not remove a tag from a topic if the topic
had another tag that was restricted to a different category.
When rendering the markdown code blocks we replace the
offending characters in the output string with spans highlighting a textual
representation of the character, along with a title attribute with
information about why the character was highlighted.
The list of characters stripped by this fix, which are the bidirectional
characters considered relevant, are:
U+202A
U+202B
U+202C
U+202D
U+202E
U+2066
U+2067
U+2068
U+2069
Currently, Discourse rate limits all incoming requests by the IP address they
originate from regardless of the user making the request. This can be
frustrating if there are multiple users using Discourse simultaneously while
sharing the same IP address (e.g. employees in an office).
This commit implements a new feature to make Discourse apply rate limits by
user id rather than IP address for users at or higher than the configured trust
level (1 is the default).
For example, let's say a Discourse instance is configured to allow 200 requests
per minute per IP address, and we have 10 users at trust level 4 using
Discourse simultaneously from the same IP address. Before this feature, the 10
users could only make a total of 200 requests per minute before they got rate
limited. But with the new feature, each user is allowed to make 200 requests
per minute because the rate limits are applied on user id rather than the IP
address.
The minimum trust level for applying user-id-based rate limits can be
configured by the `skip_per_ip_rate_limit_trust_level` global setting. The
default is 1, but it can be changed by either adding the
`DISCOURSE_SKIP_PER_IP_RATE_LIMIT_TRUST_LEVEL` environment variable with the
desired value to your `app.yml`, or changing the setting's value in the
`discourse.conf` file.
Requests made with API keys are still rate limited by IP address and the
relevant global settings that control API keys rate limits.
Before this commit, Discourse's auth cookie (`_t`) was simply a 32 characters
string that Discourse used to lookup the current user from the database and the
cookie contained no additional information about the user. However, we had to
change the cookie content in this commit so we could identify the user from the
cookie without making a database query before the rate limits logic and avoid
introducing a bottleneck on busy sites.
Besides the 32 characters auth token, the cookie now includes the user id,
trust level and the cookie's generation date, and we encrypt/sign the cookie to
prevent tampering.

This PR introduces a new `enable_experimental_backup_uploads` site setting (default false and hidden), which when enabled alongside `enable_direct_s3_uploads` will allow for direct S3 multipart uploads of backup .tar.gz files.
To make multipart external uploads work with both the S3BackupStore and the S3Store, I've had to move several methods out of S3Store and into S3Helper, including:
* presigned_url
* create_multipart
* abort_multipart
* complete_multipart
* presign_multipart_part
* list_multipart_parts
Then, S3Store and S3BackupStore either delegate directly to S3Helper or have their own special methods to call S3Helper for these methods. FileStore.temporary_upload_path has also removed its dependence on upload_path, and can now be used interchangeably between the stores. A similar change was made in the frontend as well, moving the multipart related JS code out of ComposerUppyUpload and into a mixin of its own, so it can also be used by UppyUploadMixin.
Some changes to ExternalUploadManager had to be made here as well. The backup direct uploads do not need an Upload record made for them in the database, so they can be moved to their final S3 resting place when completing the multipart upload.
This changeset is not perfect; it introduces some special cases in UploadController to handle backups that was previously in BackupController, because UploadController is where the multipart routes are located. A subsequent pull request will pull these routes into a module or some other sharing pattern, along with hooks, so the backup controller and the upload controller (and any future controllers that may need them) can include these routes in a nicer way.
* FIX: Preserve field types when updating revision
When a post was edited quickly twice by the same user, the old post
revision was updated with the newest changes. To check if the change
was reverted (i.e. rename topic A to B and then back to A) a comparison
of the initial value and last value is performed. If the check passes
then the intermediary value is dismissed and only the initial value and
the last ones are preserved. Otherwise, the modification is dismissed
because the field returned to its initial value.
This used to work well for most fields, but failed for "tags" because
the field is an array and the values were transformed to strings to
perform the comparison.
* FIX: Reset last_editor_id if revision is reverted
If a post was revised and then the same revision was reverted,
last_editor_id was still set to the ID of the user who last edited the
post. This was a problem because the same person could then edit the
same post again and because it was the same user and same post, the
system attempted to update the last one (that did not exist anymore).
This commit introduces a new s3:ensure_cors_rules rake task
that is run as a prerequisite to s3:upload_assets. This rake
task calls out to the S3CorsRulesets class to ensure that
the 3 relevant sets of CORS rules are applied, depending on
site settings:
* assets
* direct S3 backups
* direct S3 uploads
This works for both Global S3 settings and Database S3 settings
(the latter set directly via SiteSetting).
As it is, only one rule can be applied, which is generally
the assets rule as it is called first. This commit changes
the ensure_cors! method to be able to apply new rules as
well as the existing ones.
This commit also slightly changes the existing rules to cover
direct S3 uploads via uppy, especially multipart, which requires
some more headers.
FinalDestination's follow_canonical mode used for embedded topics should work when canonical URLs are relative, as specified in [RFC 6596](https://datatracker.ietf.org/doc/html/rfc6596)
We are no longer able to display the image returned by Instagram directly within a Discourse site (either in the composer, or within a cooked post within a topic), so:
- Display an image placeholder in the composer preview
- A cooked post should use an iframe to display the Instagram 'embed' content
The `白名单` term becomes `名单 白名单` after it is processed by
cppjieba in :query mode. However, `白名单` is not tokenized as such by cppjieba when it
appears in a string of text. Therefore, this may lead to failed matches as
the search data generated while indexing may not contain all of the
terms generated by :query mode. We've decided to maintain parity for now
such that both indexing and querying uses the same :mix mode. This may
lead to less accurate search but our plan is to properly support CJK
search in the future.
In preparation for adding automatic CORS rules creation
for direct S3 uploads, I am adding tests here and moving the
CORS rule definitions into a dedicated class so they are all
in the one place.
There is a problem with ensure_cors! as well -- if there is
already a CORS rule defined (presumably the asset one) then
we do nothing and do not apply the new rule. This means that
the S3BackupStore.ensure_cors method does nothing right now
if the assets rule is already defined, and it will mean the
same for any direct S3 upload rules I add for uppy. We need
to be able to add more rules, not just one.
This is not a problem on our hosting because we define the
rules at an infra level.
* FIX: allowed_theme_ids should not be persisted in GlobalSettings
It was observed that the memoized value of `GlobalSetting.allowed_theme_ids` would be persisted across requests, which could lead to unpredictable/undesired behaviours in a multisite environment.
This change moves that logic out of GlobalSettings so that the returned theme IDs are correct for the current site.
Uses get_set_cache, which ultimately uses DistributedCache, which will take care of multisite issues for us.
