The check used to be necessary because we validated the referrer too and
this bypass was a workaround a bug that is present in some browsers that
do not send the correct referrer.
When creating a group membership request, there is no character
limit on the 'reason' field. This can be potentially be used by
an attacker to create enormous amount of data in the database.

Only allow maximum of `50_000` characters for chat drafts. A hidden `max_chat_draft_length` setting can control this limit. A migration is also provided to delete any abusive draft in the database.
The number of drafts loaded on current user has also been limited and ordered by most recent update.
Note that spec files moved are not directly related to the fix.

Currently we don’t have an association between reviewables and posts.
This sometimes leads to inconsistencies in the DB as a post can have
been deleted but an associated reviewable is still present.
This patch addresses this issue simply by adding a new association to
the `Post` model and by using the `dependent: :destroy` option.
This is just cleaning up a TODO I had to add more specs
to this controller -- there are more thorough tests on the
actual HashtagService class and the type-specific hashtag
classes.
When a user checks "Open all external links in a new tab" preference
he expects not to be overruled by unrelated text selections.
Yet if text is selected during a link click the link is followed on
the same tab. This change corrects that.
In dev/prod, these are absorbed by unicorn. Most commonly, they occur when a client interrupts a message-bus long-polling request.
Also reverts the EPIPE workaround introduced in 011c9b9973
There was an issue where if hashtag-cooked HTML was sent
to the ExcerptParser without the keep_svg option, we would
end up with empty </use> and </svg> tags on the parts of the
excerpt where the hashtag was, in this case when a post
push notification was sent.
Fixed this, and also added a way to only display a plaintext
version of the hashtag for cases like this via PrettyText#excerpt.
We've had the UploadReference table for some time now in core,
but it was added after ChatUpload was and chat was just never
moved over to this new system.
This commit changes all chat code dealing with uploads to create/
update/delete/query UploadReference records instead of ChatUpload
records for consistency. At a later date we will drop the ChatUpload
table, but for now keeping it for data backup.
The migration + post migration are the same, we need both in case
any chat uploads are added/removed during deploy.
When checking whether an existing upload should be secure
based on upload references, do not count deleted posts, since
there is still a reference attached to them. This can lead to
issues where e.g. an upload is used for a post then later on
a custom emoji.

This change has two goals:
- Fixes an issue when the user had zoomed the viewport and the popper would position on the opposite side
- Makes msg actions arguably more pleasant to the eye by preventing it to be right aligned with the message container
Prior to this fix trashed channels would still prevent a channel with the same slug to be created. This commit generates a new slug on trash and frees the slug for future usage.
The format used for the slug is: `YYYYMMDD-HHMM-OLD_SLUG-deleted` truncated to the max length of a channel name.
This commit allows us to set the channel slug when creating new chat
channels. As well as this, it introduces a new `SlugsController` which can
generate a slug using `Slug.for` and a name string for input. We call this
after the user finishes typing the channel name (debounced) and fill in
the autogenerated slug in the background, and update the slug input
placeholder.
This autogenerated slug is used by default, but if the user writes anything
else in the input it will be used instead.
