When a post is created using the API and goes into the review queue, we
would return a 'null' string in the response which isn't valid JSON.

So it can easily be overwritten in a plugin for example.
### Added more tests to provide better coverage
We previously only had `u.silenced_till IS NULL` but I made it consistent with pretty much every other places where we check for "active" users.
These two new lines do change the query a tiny bit though.
**Before**
- You could not get the badge if you were currently silenced (no matter what period is being checked)
- You could get the badge if you were suspended 😬
**After**
- You can't get the badge if you were silenced during the past year
- You can't get the badge if you were suspended during the past year
### Improved the performance of the query by using `NOT EXISTS` instead of `LEFT JOIN / COUNT() = 0`
There is no difference in behaviour between
```sql
LEFT JOIN user_badges AS ub ON ub.user_id = u.id AND ...
[...]
HAVING COUNT(ub.*) = 0
```
and
```sql
NOT EXISTS (SELECT 1 FROM user_badges AS ub WHERE ub.user_id = u.id AND ...)
```
The only difference is performance-wise. The `NOT EXISTS` is 10-30% faster on very large databases (aka. posts and users in X millions). I checked on 3 of the largest datasets I could find.
We provide a `.ruby-version.sample` file that we use for warning developers
about the minimum recommended Ruby version to run Discourse.
https://github.com/discourse/discourse/blob/d24dfe8f96c4151cbd6dbcc2313b42a0bf291c7d/config/application.rb#L15-L20
But if people copy the sample to a `.ruby-version` file it would be added
next time they commit.
This adds the `.ruby-version` file to `.gitignore` so it doesn't get commited
by mistake and developers can test Discourse on other versions of Ruby if
they want to.
Inspired by [this suggestion](https://meta.discourse.org/t/what-is-a-here-mention/217878/3) from G Ann Campbell
> I suppose the description of the “here mention” field could be improved to something like:
> "Name used for @here mention to allow a privileged user to notify up to 10 people participating in the thread. Must not…"
Partially revert f490a8d39a because we aren't able to
load more than the initially preloaded voters.
We were always trying to load the 1st page of voters.
Also removed the "remove users who changed their vote" logic as it was not properly working in multiple choices polls.

When initially released, the polls had a different design that didn't interact
well with the quote button - https://meta.discourse.org/t/31586
Now that the design has evolved, not being able to select text from inside a poll is
counter productive, so it's enabled again.
This setting allows admin to de/activate automatic trimming of incoming email.
There are instances where it does wonders in trimming all the garbage content and other
instances where it's so bad that it trims the most important part of the email.
FIX: don't remove hidden content using the style attribute when converting HTML to Markdown.
The regexp used was doing more harm than good. It was way too broad.
FIX: properly elide signatures from emails sent with Front App.
This is fairly safe as Front App nicely identifies signatures in the HTML part.
Let's say you want to use a gem in a plugin that has a dependencie.
You would write something like this:
```ruby
gem 'dependency-gem', '1.2.3'
gem 'amazing-gem', '4.5.6'
```
However, since when we install a plugin gem we install it in the `gems`
directory created inside the plugins directory, when it comes the time
to install the `amazing-gem`, it won't be able to find the `dependency-gem`.
This fixes that issue by adding the `gems` plugins directory to the global gem path.
Also fixed a frozen string error when specifying a source.
* DEV: small refactor of the category_moderators method
Used `index_by(&:id)` instead of `map { |u| [u.id, u] }.to_h` thanks to @cvx's recommendation.
Also renamed the `moderators` variable to not clash with method of the same name.
In the about page, we list a certain number of category moderators.
This rewrites the SQL query used to retrieve the most recent category moderators in order
to perform better with a large number of users/categories/category moderators.
TIL: you can ORDER BY inside an ARRAY_AGG in postgres
TIL: you can slide ARRAYS in postgres
Run the 'MigrateSearchDataAfterDefaultLocaleRename' post migration in batches of 500k records.
This will hopefully prevent any potential deadlocks on large tables.
Not when doing a site-wide search like we do in the Directory.
This solves the following specfailure:
1) DirectoryItemsController with data finds user by name
Failure/Error: expect(json['directory_items'].length).to eq(1)
expected: 1
got: 0
(compared using ==)
# ./spec/requests/directory_items_controller_spec.rb:88:in `block (3 levels) in <main>'
# ./spec/rails_helper.rb:271:in `block (2 levels) in <top (required)>'
# ./bundle/ruby/2.7.0/gems/webmock-3.11.1/lib/webmock/rspec.rb:37:in `block (2 levels) in <top (required)>'
When doing a user search (eg. when mentioning a user) we will not prioritie
users who hasn't been seen in over a year.
REFACTOR the user-search specs to be more precise regarding the ordering
Lots of changes but it's mostly a refactoring.
The interesting part that was fix are the 'load_problem_<model>_ids' methods.
They will now return records with no search data associated so they can be properly indexed for the search.
This "bad" state usually happens after a migration.
* FIX: show/hide ignored users preferences
based on the current user trust level and the appropriate site setting.
* Allow us to await the `updateCurrentUser` call

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...
When a tab is open but left unattended for a while, the red, green, and blue
pills tend to go out of sync.
So whevener we open the notifications menu, we sync up the notification count
(eg. blue and green pills) with the server.
However, the reviewable count (eg. the red pill) is not a notification and
is located in the hamburger menu. This commit adds a new route on the server
side to retrieve the reviewable count for the current user and a ping
(refreshReviewableCount) from the client side to sync the reviewable count
whenever they open the hamburger menu.
REFACTOR: I also refactored the hamburger-menu widget code to prevent repetitive uses
of "this.".
PERF: I improved the performance of the 'notify_reviewable' job by doing only 1 query
to the database to retrieve all the pending reviewables and then tallying based on the
various rights.
Running the reorder rake task was triggering the following error:
PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "post_timings_unique"
I re-worked the queries and refactored to use the same couple of queries for all similar tables/columns.
Was tired of seeing the following warnings in the logs
```
/discourse/app/jobs/scheduled/old_keys_reminder.rb:7: warning: already initialized constant Jobs::OldKeysReminder::OLD_CREDENTIALS_PERIOD
/discourse/app/jobs/scheduled/old_keys_reminder.rb:7: warning: previous definition of OLD_CREDENTIALS_PERIOD was here
```
When doing a migration, there might be some cases where the discobot user
doesn't have a user_option / user_profile record(s).
This ensures we always create one during the seed phase.
The previous fix (f43c0a5d85) wasn't working for images that were already uploaded.
The "metadata" (eg. 'for_*' and 'secure' attributes) were not added to existing uploads.
Also used 'Upload.get_from_url' is the admin/site_setting controller to properly retrieve
an upload from its URL.
Fixed the Upload::URL_REGEX to use the \h (hexadecimal) for the SHA
Follow-up-to: f43c0a5d85
When uploading an image as a site setting, we need to return the "raw" URL, otherwise
when saving the site setting, the upload won't be looked up properly.
Follow-up-to: f11363d446
In 91c89df6, I fixed the onebox to support local topics with a slug-less URL.
This commit fixes all the other spots (search, topic links and user badges) where we look up for a local topic.
Follow-up-to: 91c89df6
In French, the help trigger has a raw content of "afficher l'aider" which is then cooked into "afficher l’aide" (note the different quote character).
Since we were checking the raw content of the trigger against the cooked version of the post, this trigger never worked in French.
This changes so that we cook the trigger before checking in against the cooked version of the post.
DEV: new 'discobot_username' method that is used everywhere instead of 'discobot_user.username' / 'discobot_user.username_lower'
When rebaking a post we were invalidating _regular_ oneboxes but not inline oneboxes.
DEV: also renamed 'InlineOneboxer.purge' to 'InlineOneboxer.invalidate' to keep
the API consistent with 'Oneboxer.invalidate'
When linking to a topic in the same Discourse, we try to onebox the link to show the title
and other various information depending on whether it's a "standard" or "inline" onebox.
However, we were not properly detecting links to topics that had no slugs (eg. https://meta.discourse.org/t/1234).
- Stream the queries that load the imported_ids
- Use an array instead of a hash for keeping the mapping between imported_ids and new ids
- Ensure we always treat the imported_ids as integers instead of strings
It might happen that some User records have no associated primary emails.
In which case we don't ever want to send them a digest.
Also added a new "user_email_no_email" skipped email log to ensure these cases
are properly handled and surfaced.
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.

DEV: remove unused 'sanitize' gem
Wow, did you just read all that?! Congratz, here's a cookie: 🍪.
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'.
The data-vocabulary.org schema is being deprecated.
We're now using the BreadcrumList data from the latest and greatest schema.org.
FIX: categories_breadcrumb helper to support more than 2 levels of categories.
FIX: raised a proper NotFound exception when filtering groups by username with invalid username.
FIX: properly filter the groups based on current user visibility when viewing another user's groups.
DEV: Guardian.can_see_group?(group) is now using Guardian.can_see_groups(groups) instead of duplicating the same code.
FIX: spec for groups_controller#index when group directory is disabled for logged in user.
FIX: groups_controller.sortable specs to actually test all sorting combinations.
DEV: s/response_body/body/g for slightly shorter spec code.
FIX: rewrote the "view another user's groups" specs to test all group_visibility and members_group_visibility combinations.
DEV: Various refactoring for cleaner and more consistent code.
When uploading a theme/component, depending on the extension of the
file and the OS/Browser being used, the content type might differ.
This adds the "application/x-zip-compressed" content type that is being
sent by most Browsers on latest Windows when uploading a .zip file.
When a user accepts an invite with an email address that matches a group
which automatically awards its members Trust Level 2, a race condition might happen
when the 'send_advanced_tutorial_message' job runs.
That job is enqueued inside the 'user_promoted' event which is triggered inside a
transaction on the user record. If the job runs before the transaction is done,
the user record is invisible and this generates an exception.
The script will now correct all width/height and thumbnail_width/thumbnail_height properties of all the uploaded images.
The script now uses width * height to filter out all unaffected images.
Also handled the case where a downsized image was already an uploaded record.
Overwriting the same file with 'convert' is not always working as expected.
Adding a temporary file as the destination of the downsize makes this operation much more reliable.
Also switched to using (the more aggressive) 50% resize instead of halving the number of pixels.
We were counting all the oneboxes in the DOM instead of just the ones in the preview.
Also refactored the logic to count up to 'max_oneboxes_per_post` instead of down to 0.
That also ensured we don't load 11 oneboxes when the setting is limiting to 10.
