Backports the following:
* 40e8912395
* bbcb69461f
Which were showing an error when users were
trying to claim invites multiple times and
a subsequent follow-up fix.
This commit adds a check that runs regularly as per
2d68e5d942 which tests the
credentials of groups with SMTP or IMAP enabled. If any issues
are found with those credentials a high priority problem is added to the
admin dashboard.
This commit also formats the admin dashboard differently if
there are high priority problems, bringing them to the top of
the list and highlighting them.
The problem will be cleared if the issue is fixed before the next
problem check, or if the group's settings are updated with a valid
credential.
* FEATURE: hide_email_address_taken forces use of email in forgot password form
This strengthens this site setting which is meant to be used to harden sites
that are experiencing abuse on forgot password routes.
Previously we would only deny letting people know if forgot password worked on not
New change also bans usage of username for forgot password when enabled
We send the reminder using the GroupMessage class, which supports removing previous messages. We can't match them by raw because they could mention different moderators. Also, I had to change the subject to remove dynamically generated values, which is necessary for finding them.
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.

We don't need it anymore. Actually, I removed using of it on the client side a long time ago, when I was working on improving blank page syndrome on user activity pages (see https://github.com/discourse/discourse/pull/14311).
This PR also removes some old resource strings that we don't use anymore. We have new strings for blank pages.
We have a couple of site setting, `slow_down_crawler_user_agents` and `slow_down_crawler_rate`, that are meant to allow site owners to signal to specific crawlers that they're crawling the site too aggressively and that they should slow down.
When a crawler is added to the `slow_down_crawler_user_agents` setting, Discourse currently adds a `Crawl-delay` directive for that crawler in `/robots.txt`. Unfortunately, many crawlers don't support the `Crawl-delay` directive in `/robots.txt` which leaves the site owners no options if a crawler is crawling the site too aggressively.
This PR replaces the `Crawl-delay` directive with proper rate limiting for crawlers added to the `slow_down_crawler_user_agents` list. On every request made by a non-logged in user, Discourse will check the User Agent string and if it contains one of the values of the `slow_down_crawler_user_agents` list, Discourse will only allow 1 request every N seconds for that User Agent (N is the value of the `slow_down_crawler_rate` setting) and the rest of requests made within the same interval will get a 429 response.
The `slow_down_crawler_user_agents` setting becomes quite dangerous with this PR since it could rate limit lots if not all of anonymous traffic if the setting is not used appropriately. So to protect against this scenario, we've added a couple of new validations to the setting when it's changed:
1) each value added to setting must 3 characters or longer
2) each value cannot be a substring of tokens found in popular browser User Agent. The current list of prohibited values is: apple, windows, linux, ubuntu, gecko, firefox, chrome, safari, applewebkit, webkit, mozilla, macintosh, khtml, intel, osx, os x, iphone, ipad and mac.
When this setting is turned on, it will check that normalized emails
are unique. Normalized emails are emails without any dots or plus
aliases.
This setting can be used to block use of aliases of the same email
address.
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.
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
* FIX: small copy fix for embedding.sample
* FIX: improve copy for site_description and short_site_description
As part of the setup wizard, improve the description of these two
strings to add context on where they will be used, so that it is
clearer how to write each one.

Sometimes administrators want to permanently delete posts and topics
from the database. To make sure that this is done for a good reasons,
administrators can do this only after one minute has passed since the
post was deleted or immediately if another administrator does it.
We aren't translating these settings, so it makes more sense to move them into the code. I added an instance method so plugins can add mappings for custom reasons.
We relied on backticks to identify and replace site setting names with links. Unfortunately, some translations don't follow this convention, breaking this feature.
Additionally, this lets us linkify `category settings` and `watched words` without using HTML in the translations.
You may notice that I split the texts we want to linkify into two groups. I did this on purpose to emphasize those that should be translated (regular_links) from those who don't (site_settings_link). If you can think of a better solution, I'm open to suggestions.
The file size error messages for max_image_size_kb and
max_attachment_size_kb are shown to the user in the KB
format, regardless of how large the limit is. Since we
are going to support uploading much larger files soon,
this KB-based limit soon becomes unfriendly to the end
user.
For example, if the max attachment size is set to 512000
KB, this is what the user sees:
> Sorry, the file you are trying to upload is too big (maximum
size is 512000KB)
This makes the user do math. In almost all file explorers that
a regular user would be familiar width, the file size is shown
in a format based on the maximum increment (e.g. KB, MB, GB).
This commit changes the behaviour to output a humanized file size
instead of the raw KB. For the above example, it would now say:
> Sorry, the file you are trying to upload is too big (maximum
size is 512 MB)
This humanization also handles decimals, e.g. 1536KB = 1.5 MB
Allows creating a bookmark with the `for_topic` flag introduced in d1d2298a4c set to true. This happens when clicking on the Bookmark button in the topic footer when no other posts are bookmarked. In a later PR, when clicking on these topic-level bookmarks the user will be taken to the last unread post in the topic, not the OP. Only the OP can have a topic level bookmark, and users can also make a post-level bookmark on the OP of the topic.
I had to do some pretty heavy refactors because most of the bookmark code in the JS topics controller was centred around instances of Post JS models, but the topic level bookmark is not centred around a post. Some refactors were just for readability as well.
Also removes some missed reminderType code from the purge in 41e19adb0d
We don't need no stinkin' denormalization! This commit ignores
the topic_id column on bookmarks, to be deleted at a later date.
We don't really need this column and it's better to rely on the
post.topic_id as the canonical topic_id for bookmarks, then we
don't need to remember to update both columns if the bookmarked
post moves to another topic.
This pull request introduces the endpoints required, and the JavaScript functionality in the `ComposerUppyUpload` mixin, for direct S3 multipart uploads. There are four new endpoints in the uploads controller:
* `create-multipart.json` - Creates the multipart upload in S3 along with an `ExternalUploadStub` record, storing information about the file in the same way as `generate-presigned-put.json` does for regular direct S3 uploads
* `batch-presign-multipart-parts.json` - Takes a list of part numbers and the unique identifier for an `ExternalUploadStub` record, and generates the presigned URLs for those parts if the multipart upload still exists and if the user has permission to access that upload
* `complete-multipart.json` - Completes the multipart upload in S3. Needs the full list of part numbers and their associated ETags which are returned when the part is uploaded to the presigned URL above. Only works if the user has permission to access the associated `ExternalUploadStub` record and the multipart upload still exists.
After we confirm the upload is complete in S3, we go through the regular `UploadCreator` flow, the same as `complete-external-upload.json`, and promote the temporary upload S3 into a full `Upload` record, moving it to its final destination.
* `abort-multipart.json` - Aborts the multipart upload on S3 and destroys the `ExternalUploadStub` record if the user has permission to access that upload.
Also added are a few new columns to `ExternalUploadStub`:
* multipart - Whether or not this is a multipart upload
* external_upload_identifier - The "upload ID" for an S3 multipart upload
* filesize - The size of the file when the `create-multipart.json` or `generate-presigned-put.json` is called. This is used for validation.
When the user completes a direct S3 upload, either regular or multipart, we take the `filesize` that was captured when the `ExternalUploadStub` was first created and compare it with the final `Content-Length` size of the file where it is stored in S3. Then, if the two do not match, we throw an error, delete the file on S3, and ban the user from uploading files for N (default 5) minutes. This would only happen if the user uploads a different file than what they first specified, or in the case of multipart uploads uploaded larger chunks than needed. This is done to prevent abuse of S3 storage by bad actors.
Also included in this PR is an update to vendor/uppy.js. This has been built locally from the latest uppy source at d613b849a6. This must be done so that I can get my multipart upload changes into Discourse. When the Uppy team cuts a proper release, we can bump the package.json versions instead.
