Improvements to make console access to IncomingEmail more pleasant, and stopping certain IMAP logs from landing in the DB because they just create too much noise,
This should make it easier to track down how the incoming email was created, which is one of four locations:
The POP3 poller (which picks up reply via email replies)
The admin email controller #handle_mail (which is where hosted mail is sent)
The IMAP sync tool
The group SMTP mailer, which sends emails when replying to IMAP topics, pre-emptively creating IncomingEmail records to avoid double syncing
It returned a 429 error code with a 'Retry-After' header if a
RateLimiter::LimitExceeded was raised and unhandled, but the header was
missing if the request was limited in the 'RequestTracker' middleware.
Admins can now edit translations in different languages without having to change their locale. We display a warning when there's a fallback language set.
Transient errors in migration are ignored, silently corrupting
data, and the migration is incomplete and misses many sources of
uploads, which will lead to an incorrect expectation of independence
from the remote object storage after announcing that the migration
was successful, regardles of whether transient errors permanently
corrupted the data.
Remove this migration until such time as it is re-written to
follow the same pattern has the migration to s3, moving the
core logic out of the task.
This PR fixes a race condition with the IMAP notification code. In the `Email::Receiver` we call the `NewPostManager` to create the post and enqueue jobs and sends alerts via `PostAlerter`. However, if the post alerter reaches the `notify_pm_users` and the `group_notifying_via_smtp` method _before_ the incoming email is updated with the post and topic, we unnecessarily send a notification to the person who just posted. The result of this is that the IMAP syncer re-imports the email sent to the user about their own post, which looks like this in the group inbox:
To fix this, we skip the jobs enqueued by `NewPostManager` and only enqueue them with `PostJobsEnqueuer` manually _after_ the incoming email record has been updated with the post and topic.
Other improvements:
* Moved code to calculate email addresses from `IncomingEmail` records into the topic, with a group passed in, for easier testing and debugging. It is not the responsibility of the post alerter to figure this stuff out.
* Add shortcut methods on `IncomingEmail` to split or provide an empty array for to and cc addresses to avoid repetition.
Feature for `Must Approve Users` setup. When a user is rejected, a staff member can optionally set a reason for audit purposes. In addition, feedback email can be sent to the user.

This PR adds functionality for the IMAP sync code to detect if a UID that is missing from the mail group mailbox is in the Spam/Junk folder for the mail account, and if so delete the associated Discourse topic. This is identical to what we do for emails that are moved for Trash.
If an email is missing but not in Spam or Trash, then we mark the incoming email record with imap_missing: true. This may be used in future to further filter or identify these emails, and perhaps go hunting for them in the email account in bulk.
Note: This adds some code duplication because the trash and spam email detection and handling is very similar. I intend to do more refactors/improvements to the IMAP sync code in time because there is a lot of room for improvement.
Splits the `ToggleTopicClosed` job into two distinct `OpenTopic` and `CloseTopic` jobs to make the code clearer. The old job cannot be deleted yet because of outstanding sidekiq schedules, so a todo has been added to do so later this year.
Also replaced mentions of `topic_status_update` with `topic_timer` in some files, because the `topic_status_update` model is obsolete and replaced by topic timer.
Added some shortcut methods for checking if a topic is open/whether a user can change an open topic.
If the sliding window size is N seconds, then a moment at the Nth second
should be considered as the moment outside of the sliding window.
Otherwise, if the sliding window is already full, at the Nth second,
a new call wouldn't be allowed, but a time to wait before the next call
would be equal to zero, which is confusing.
In other words, the end of the time range shouldn't be included in the
sliding window.
Let's say we start at the second 0, and the sliding window size is 10
seconds. In the current version of rate limiter, this sliding window will
be considered as a time range [0, 10] (including the end of the range),
which actually is 11 seconds in length.
After this fix, the time range will be considered as [0, 10)
(excluding the end of the range), which is exactly 10 seconds in length.
It was a problem because during this operation only the first frame
is kept. This commit removes the alternative solution to check if a GIF
image is animated.
* DEV: TopicTrackingState calls should happen in the background
It was observed that calling TopicTrackingState on popular topics could result in a large number of calls to redis, resulting in slow response times when posting replies.
These calls should be moved to a background job.
* DEV: PostUpdateTopicTrackingState should execute on default queue
Fixes a rare race condition causing the `Imap::Sync` class to create an incoming email and associated post/topic, which then kicks off the PostAlerter to notify others in the PM about a reply in the topic, but for the OP which is not necessary (because the person emailing the IMAP inbox already knows about the OP). Basically, we should never be sending the group SMTP email for the first post in a topic.
Also in this PR:
* Custom attribute accessors for the to/from/cc addresses on `IncomingEmail`, to parse them from an array to a joined string so the logic for this is only in one place.
* Store extra detail against the `IncomingEmail` created in `GroupSmtpMailer`
* regex test Mail header Reply-To as string instead of Field, which fixes `warning: deprecated Object#=~ is called on Mail::Field; it always returns nil`
* Add DEBUG_IMAP to log all IMAP logs as warnings for easier debugging
* Changed the Rails logging to `ImapSyncLog` in the `GroupSmtpMailer`
* FIX: Inline onebox should use encoding from Content-Type header when present
* Use Regexp.last_match(1)

- Only initialize the S3Helper when needed
- Skip initializing the S3Helper for S3Store#cdn_url
- Allow cook_url to be passed a `local` hint to skip unnecessary checks
These are a few small tweaks that slightly improve performance.
- we omitted 1 query from the post guardian which could cause an N+1
- cook_url has been sped up a bit
- url helper avoids re-creating sets for no reason
Inventory on S3 always lagged, over the past few weeks we are noticing that
1 day of lag is not enough.
We are increasing this to 2, to ensure that we do not get false positive
reports.
Final sigma is not lower cased correctly in Ruby causing issues with routing.
This works around the issue by downcasing all usernames containing a sigma using JS.
You can now use `@me` to search for posts created by yourself, this is particularly handy if you have a long username.
`@me rainbow` will find all posts you created with the word rainbow.
Also cleans up test suite so it has no warnings.
This allows plugins to call `register_demon_process` with a Class inheriting from Demon::Base. The unicorn master process will take care of spawning, monitoring and restarting the process. This API should be used with extreme caution, but it is significantly cleaner than spawning processes/threads in an `after_initialize` block.
This commit also cleans up the demon spawning logging so that it uses the same format as unicorn worker logging. It also switches to the block form of `fork` to ensure that Demons exit after running, rather than returning execution to where the fork took place.
`/srv/status` routes should not be cached at all. Also, we want to
decouple the route from Redis which `AnonymouseCache` relies on. The
`/srv/status` should continue to return a success response even if Redis
is down.
This is an edge-case of 9fb3629. An admin could set the shared draft category to one where both TL2 and TL3 users have access but only give shared draft access to TL3 users. If something like this happens, we need to make sure that TL2 users won't be able to see them, and they won't be listed on latest.
Before this change, `SharedDrafts` were lazily created when a destination category was selected. We now create it alongside the topic and set the destination to the same shared draft category.
* FEATURE: Allow categroy group moderators to list/unlist topics
If enabled via SiteSettings, a user belonging to a group which has been granted category group moderator privileges should be able to list/unlist topics belonging to the appropraite category.
It used to insert block Oneboxes inside paragraphs which resulted in
invalid HTML. This needed an additional parsing for removal of empty
paragraphs and the resulting HTML could still be invalid.
This commit ensure that block Oneboxes are inserted correctly, by
splitting the paragraph containing the link and putting the block
between the two. Paragraphs left with nothing but whitespaces will
be removed.

* FIX: 'false' value was treated as a truthy value
For example, latest.json?no_subcategories=false used to have set
no_subcategories to the string value of 'false', which is not false.
* DEV: Remove dead code
* FIX: Redirect to /none under the right conditions
These conditions are:
- neither /all or /none present
- only for default filter
* FIX: Build correct topic list filter
/none was never added to the topic list filter
* FIX: Do not show count for subcategories if 'none' category
* FIX: preload_key must contain /none if no_subcategories
All the data we need for the `info` and `credentials` auth hash
are obtained via the user info API, not the JWT. Using and verifying
the JWT can fail due to clock skew, so let's skip it completely.

Previously it matched the behavior of standard ActiveRecord after_commit callbacks. They do not work well within `joinable: false` nested transactions. Now `DB.after_commit` callbacks will only be run when the outermost transaction has been committed.
Tests always run inside transactions, so this also introduces some logic to run callbacks once the test-wrapping transaction is reached.
* DEV: More robust processing of URLs
The previous `UrlHelper.encode_component(CGI.unescapeHTML(UrlHelper.unencode(uri))` method would naively process URLs, which could result in a badly formed response.
`Addressable::URI.normalized_encode(uri)` appears to deal with these edge-cases in a more robust way.
* DEV: onebox should use UrlHelper
* DEV: fix spec
* DEV: Escape output when rendering local links
You can let non-staff users use shared drafts by modifying the `shared_drafts_min_trust_level` site setting. These users must have access to the shared draft category.
* FEATURE: Allow Category Group Moderators to edit topic titles
Adds category group moderators to the topic guardian’s `can_edit` method.
The value of `can_edit` is returned by the topic view serializer, and this value determines whether the current user can edit the title/category/tags of the topic directly (which category group moderators could already do by editing the first post of a topic).
Note that the value of `can_edit` is now always returned by the topic view serializer (ie, for both true and false values) to cover the case where a topic is moved out of a category that a category group moderator has permissions on, so that when the topic is reloaded the UI picks up that `can_edit` is now false, and thus the edit icon should no longer be displayed.
* DEV: Add a comment explaining why `can_edit` is always returned
If a category and a sub-category have the same slug, adding a background to one of them will also show it on the other one. This was introduced in 8e3f667 to fix a discrepancy, which was later fixed in 214b4c3.
We can't use erb in ember-cli, and it seems the emoji groups rarely

Force pushing a commit to a theme repository used to break the updater,
because the system was not able to count the commits behind the old and
new version. This operation failed because a force push deleted the old
commits.
The user was prompted with a simple "500 server error" message.
When calculating whether the attached uploads went over the SiteSetting.email_total_attachment_size_limit_kb.kilobytes limit, we were using the original_upload for the calculation instead of the actually attached_upload, which will be smaller in most cases because it can be an optimized image.
This adds a new min_trust_level_to_allow_ignore site setting that enables admins to control the point at which a user is allowed to ignore other users.
After the search term is parsed for advanced search filters, the term may
become empty. Later, the same term will be passed to Discourse.route_for
which will raise an ArgumentError.

Partial revert of b143412be4 (the refactoring is not reverted)
This broke a few things, so we need to investigate and make some changes before reinstating the error
Hopefully this will prevent fellow developers from spending a morning
trying to figure out why the jobs that are run after a post is created
are not finding the post in the database.
That's because if you're inside a transaction when creating a post, the jobs
will likely run before the transaction is being commited to the database.
There was a "warning" in the comments of the PostCreator class but raising an
exception should hopefully help catch those issue much faster :fingers_crossed:.
This is hard to test since all the tests are run in a transaction...
* FEATURE: display error if Oneboxing fails due to HTTP error
- display warning if onebox URL is unresolvable
- display warning if attributes are missing
* FEATURE: Use new Instagram oEmbed endpoint if access token is configured
Instagram requires an Access Token to access their oEmbed endpoint. The requirements (from https://developers.facebook.com/docs/instagram/oembed/) are as follows:
- a Facebook Developer account, which you can create at developers.facebook.com
- a registered Facebook app
- the oEmbed Product added to the app
- an Access Token
- The Facebook app must be in Live Mode
The generated Access Token, once added to SiteSetting.facebook_app_access_token, will be passed to onebox. Onebox can then use this token to access the oEmbed endpoint to generate a onebox for Instagram.

This moves the library into our lib folder, and refactored it to more
modern Javascript. I've kept the MIT license at the top of the file.
Doing this allows us to import it as a library in Ember CLI and ditch
yet another global variable.
Previously thumbnails were only preloaded for queries using `TopicQuery#default_results`, which meant that requests for PM topic lists would lead to N+1 queries.
This commit moves the preloading into TopicList#load_topics, along with other similar preloads (e.g. plugin custom fields)
The direct call to `ActiveRecord::Associations::Preloader#preload` is necessary because `@topics` can be an array, not an `ActiveRecord::Relation`
Themes marked for auto update will be automatically updated when
Discourse is updated. This is triggered by discourse_docker or
docker_manager running Rake task 'themes:update'.
CookedPostProcessor replaces all large images with their optimized
versions, but for GIF images the optimized version is limited to first
frame only. This caused animations it cooked posts to require a click
to show up the lightbox and start playing.
Animated emojis were converted to static images. This commit moves the
responsability on site admins to optimize their animated emojis before
uploading them (gifsicle is no longer used).
Plugin client.en.yml and server.en.yml can now be client/server-(1-100).en.yml. 1 is the lowest priority, and 100 is the highest priority. This allows plugins to set their priority higher than other plugins, so that they can override eachothers' translations.
It used to simply say "title is invalid" without giving any hint what
the problem could be. This commit adds different errors messages for
all caps titles, low entropy titles or titles with very long words.
- Bump rails_failover for new per-backend callback feature

- If a single backend fails over, make that individual site readonly. And vice-versa for fallback
- When a single backend fails, also check connection to the master backend
Previously, `/u/by-external/{id}` would only work for 'Discourse SSO' systems. This commit adds a new 'provider' parameter to the URL: `/u/by-external/{provider}/{id}`
This is compatible with all auth methods which have migrated to the 'ManagedAuthenticator' pattern. That includes all core providers, and also popular plugins such as discourse-oauth2-basic and discourse-openid-connect.
The new route is admin-only, since some authenticators use sensitive information like email addresses as the external id.
This commit adds an additional find_user_by_email hook to ManagedAuthenticator so that GitHub login can continue to support secondary email addresses
The github_user_infos table will be dropped in a follow-up commit.
This is the last core authenticator to be migrated to ManagedAuthenticator 🎉
PostDestroyer should accept the option to permanently destroy post from the database. In addition, when the first post is destroyed it destroys the whole topic.
Currently, that feature is limited to private messages and creator of the post. It will be used by discourse-encrypt to explode encrypted private messages.
When embedding secure images which have been oneboxed, we checked to see if the image's parent's parent had the class onebox-body. This was not always effective as if the image does not get resized/optimized then it does not have the aspect-image div wrapping it. This would cause the image to embed in the email but be huge.
This PR changes the check to see if any of the image's ancestors have the class onebox-body, or if the image has the onebox-avatar class to account for variations in HTML structure.
Per Google, sites are encouraged to upgrade from Universal Analytics v3 `analytics.js` to v4 `gtag.js` for Google Analytics tracking. We're giving admins the option to stay on the v3 API or migrate to v4. Admins can change the implementation they're using via the `ga_version` site setting. Eventually Google will deprecate v3, but our implementation gives admins the choice on what to use for now.
We chose this implementation to make the change less error prone, as many site admins are using custom events via the v3 UA API. With the site stetting defaulted to `v3_analytics`, site analytics won't break until the admin is ready to make the migration.
Additionally, in the v4 implementation, we do not enable automatic pageview tracking (on by default in the v4 API). Instead we rely on Discourse's page change API to report pageviews on transition to avoid double-tracking.
There are issues around displaying images on published pages when secure media is enabled. This PR temporarily makes it appear as if published pages are enabled if secure media is also enabled.
* FEATURE - allow category group moderators to delete topics
* Allow individual posts to be deleted
* DEV - refactor for new `can_moderate_topic?` method
Previous to this change our anonymous rate limits acted as a throttle.
New implementation means we now also consider rate limited requests towards
the limit.
This means that if an anonymous user is hammering the server it will not be
able to get any requests through until it subsides with traffic.
See #10794 for original context.
I did not mean to add invite to the BYPASS_TYPES for Email::Sender, it was supposed to be invite_password_instructions.
A site owner attempting to use both the email_subject site setting and translation overrides for normal post notification
email subjects would find themselves frusturated at the lack of template argument parity.
Make all the variables available for translation overrides by adding the subject variables to the custom interpolation keys list and applying them.

This commit adds a site setting `auto_close_topics_create_linked_topic`
which when enabled works in conjunction with `auto_close_topics_post_count`
setting and creates a new linked topic for the topic just closed.
The auto-created new topic contains a link for all the previous topics
and the topic titles are appended with `(Part {n})`.
The setting is enabled by default.
We had an issue where onebox thumbnail was too large and thus was optimized, and we are using the image URLs in post to redact and re-embed, based on the sha1 in the URL. Optimized image URLs have extra stuff on the end like _99x99 so we were not parsing out the sha1 correctly. Another issue I found was for posts that have giant images, the original was being used to embed in the email and thus would basically never get included because it is huge.
For example the URL 787b17ea61_2_690x335.jpeg was not parsed correctly; we would end up with 787b17ea6140f4f022eb7f1509a692f2873cfe35_2_690x335.jpeg as the sha1 which would not find the image to re-embed that was already attached to the email.
This fix will use the first optimized image of the detected upload when we are redacting and then re-embedding to make sure we are not sending giant things in email. Also, I detect if it is a onebox thumbnail or the site icon and force appropriate sizes and styles.
We remove the slow mode composer message and provide better messages when rejecting new posts and edits. The client now validates if the user tries to post again immediately. Finally, we replaced the `hourglass-end` icon with the `hourglass-start` one.
This reverts commit e3de45359f.
We need to improve out strategy by adding a cache breaker with this change ... some assets on CDNs and clients may have incorrect CORS headers which can cause stuff to break.
There is a site setting reply_by_email_enabled which when combined with reply_by_email_address creates a Reply-To header in emails in the format "test+%{reply_key}@test.com" along with a PostReplyKey record, so when replying Discourse knows where to route the reply.
However this conflicts with the IMAP implementation. Since we are sending the email for a group via SMTP and from their actual email account, we want all replys to go to that email account as well so the IMAP sync job can pick them up and put them in the correct place. So if the group has IMAP enabled and configured, then the reply-to header will be correct.
This PR also makes a further fix to 64b0b50 by using the correct recipient user for the PostReplyKey record. If the post user is used we encounter this error:
if destination.user_id != user.id && !forwarded_reply_key?(destination, user)
raise ReplyUserNotMatchingError, "post_reply_key.user_id => #{destination.user_id.inspect}, user.id => #{user.id.inspect}"
end
This is because the user above is found from the from_address, but the destination which is the PostReplyKey is made by the post.user, which will be different people.
When plugin spec is evaluated for the first time, it took 30 seconds to run:
```

Applying sprocket patch in test environment solves that issue
On forums with a large amount of posts when a user had a bookmark in the topic, PostgreSQL was using an inefficient query plan to fetch the first post of the topic. When running this ActiveRecord query:
```
topic.posts.with_deleted.where(post_number: 1).first
```
The following query plan was produced:
```
Limit (cost=0.43..583.49 rows=1 width=891) (actual time=3850.515..3850.515 rows=1 loops=1)
-> Index Scan using posts_pkey on posts (cost=0.43..391231.51 rows=671 width=891) (actual time=3850.514..3850.514
rows=1 loops=1)
Filter: ((topic_id = 160918) AND (post_number = 1))
Rows Removed by Filter: 2274520
Planning time: 0.200 ms
Execution time: 3850.559 ms
(6 rows)
```
The issue here is the combination of ORDER BY and LIMIT causing the ineficcient Index Scan using posts_pkey on posts to be used. When we correct the AR call to this:
```
topic.posts.with_deleted.find_by(post_number: 1)
```
We end up with a query that still has a LIMIT but no ORDER BY, which in turn creates a much more efficient query plan:
```
Limit (cost=0.43..1.44 rows=1 width=891) (actual time=0.033..0.034 rows=1 loops=1)
-> Index Scan using index_posts_on_topic_id_and_post_number on posts (cost=0.43..678.82 rows=671 width=891) (actua
l time=0.033..0.033 rows=1 loops=1)
Index Cond: ((topic_id = 160918) AND (post_number = 1))
Planning time: 0.167 ms
Execution time: 0.072 ms
(5 rows)
```
This query plan uses the correct index, `Index Scan using index_posts_on_topic_id_and_post_number on posts`. Note that this is only a problem on forums with a larger amount of posts; tiny forums would not notice the difference. On large forums a query for a topic that takes 1s without a bookmark can take 8-30 seconds, and even end up with 502 errors from nginx.
* FEATURE - Add SiteSettings to control JPEG image quality
`recompress_original_jpg_quality` - the maximum quality of a newly
uploaded file.
`image_preview_jpg_quality` - the maximum quality of OptimizedImages
* FEATURE: allow category group moderators to edit posts
If the `enable_category_group_moderation` SiteSetting is enabled, posts should be editable by those belonging to the appropraite groups.
Previously if a onebox timed out we would not present the users in the log
with any information regarding the onebox. This makes it very difficult to
debug.
This adds url/topic/user in the debugging output.
`max-width: 50%; max-height: 400px;` is a good fallback, however, if width and height are given and are smaller than fallback - we should persist that smaller size.
Our Email::Sender class accepts an optional user argument, which is used to create a PostReplyKey record when present. This record is used to sub out the %{reply_key} placeholder in the Reply-To mail header, so if we do not pass in the user we get a broken Reply-To header.
This is especially problematic in the IMAP group SMTP situation, because these emails go to customers that we are replying to, and when they reply to us the email bounces! This fixes the issue by passing user to the Email::Sender when sending a group_smtp email but there is still more to do in another PR.
This Email::Sender optional user is a bit of a footgun IMO, especially because most of the time we use it there is a user we can source. I would like to do another PR for this after this one to make the parameter not optional, so we don't end up with these reply issues down the line again.
