selection when multiple parents exist.

FIX: Recursively tag topics with missing ancestor tags (#18344)
* FIX: Recursively tag topics with missing ancestor tags

Given only a child tag, walk up the ancestry chain, get all of it's
ancestors for use in tagging a topic

* FIX: Ensure only one parent tag is returned for topic tagging

Current implementation selects and return first parent tag if child tag
has multiple parents.

This change updates recursive parent tag implementation to only return
parent tags via only one ancestry line.

* DEV: Add test case for tag cycles

Given we aren't performing a strict graph traversal to get a tag's
parent, cycles do not have any effect on the tags returned for topic
tagging.

FEATURE: Allow multiple required tag groups for a category (#16381)
Previously we only supported a single 'required tag group' for a category. This commit allows admins to specify multiple required tag groups, each with their own minimum tag count.

A new category_required_tag_groups database table replaces the existing columns on the categories table. Data is automatically migrated.

FIX: Validate category tag restrictions before sending new topics to review (#16292)
Tags (and tag groups) can be configured so that they can only be used in specific categories and (optionally) restrict topics in these categories to be able to add/use only these tags. These restrictions work as expected when a topic is created without going through the review queue; however, if the topic has to be reviewed by a moderator then these restrictions currently aren't checked before the topic is sent to the review queue, but they're checked later when a moderator tries to approve the topic. This is because if a user manages to submit a topic that doesn't meet the restrictions, moderators won't be able to approve and it'll be stuck in the review queue.

This PR prevents topics that don't meet the tags requirements from being sent to the review queue and shows the poster an error message that indicates which tags that cannot be used.

Internal ticket: t60562.

DEV: Fix a flaky validation message (#16141)
The order of tags in the validation error message could be random, which we don't really care about, but it made the specs flake out once in a while.

The flaky specs were:

FIX: Show required tags to staff by default and override limit (#13242)
This improves the display of available tags in categories that are
configured to require at least (x) tags from a tag group.

There are two changes included:
- regular users will now see all the available tags in the required tag
group (previously they could see a max. of 5 tags)
- staff users will now see the tags from the required tag group when
the tag group contains more tags than the default limit (also set to 5)

Both changes only apply to the default query (i.e. no search terms).

FIX: Enforce tag group count validation before sending to review queue (#12728)
There is a category setting that enforces 1 or more tags must be added to a topic from a specific tag group before creating it. This validation was not being run before the topic was being sent to a review queue for categories that have that setting enabled.

There was an existing validation in `TopicCreator` but it was not correct; it was only validating when the tags did _not_ exist and also only happened on `create`. I now run the validation in `TopicCreator.valid?`

I also improved the error message shown to the user when they have not added the tags required (showing the tag names from the tag group), and changed the composer tag selector to not show "optional" if there are N tags required from a certain group.

has been called (because this is when the associations are created/
destroyed). The event has the topic, then a second param with the
old and new tag names in arrays for easy inspection.

FIX: Return 422 when creating topics with tags w/out permission (#10400)
The UI prevents users from trying to create tags on topics when they
don't have permission, but if you are trying to add tags to a topic via
the API and you don't have permission before this change it would
silently succeed in creating the topic, but it wouldn't have any tags.

Now a 422 error will be returned with an error message when trying to
create a topic with tags when tagging is disabled or you don't have
enough trust level to add tags to a topic.

FEATURE: Tag synonyms
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.

Sam Saffron 88ecb650a9 DEV: Implement a faster Discourse.cache
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.

REFACTOR: redo DiscourseTagging.filter_allowed_tags (#8328)
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

Neil Lalonde b6d140e4bd UX: tag input suggests required tags if none have been selected
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.

Sam Saffron 0a5a6dfded DEV: stop mutating inputs as a side effect
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.

Neil Lalonde c2a8a2bc97 FIX: if mandatory parent tag is missing, add it
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.

tags and tag groups in the category.

FEATURE: Mixed case tagging (#6454)
- By default, behaviour is not changed: tags are made lowercase upon creation and edit.

- If force_lowercase_tags is disabled, then mixed case tags are allowed.

- Tags must remain case-insensitively unique. This is enforced by ActiveRecord and Postgres.

- A migration is added to provide a `UNIQUE` index on `lower(name)`. Migration includes a safety to correct any current tags that do not meet the criteria.

- A `where_name` scope is added to `models/tag.rb`, to allow easy case-insensitive lookups. This is used instead of `Tag.where(name: "blah")`.

- URLs remain lowercase. Mixed case URLs are functional, but have the lowercase equivalent as the canonical.
