If a status with a hashtag becomes very popular, it stands to
reason that the hashtag should have a chance at trending
Fix no stats being recorded for hashtags that are not allowed
to trend, and stop ignoring bots

As far as I understand, the brakeman warning was a false-positive as
`content_tag` properly escapes untrusted HTML. Furthermore, the interpolated
string values are built from the “username” part of accounts, which is
restricted to a small subset of ASCII that precludes any XML entity or HTML
code.
This proposed change should be functionally equivalent to the current code,
however it is slightly more robust, it's more idiomatic, and Brakeman will
stop complaining about it.
The exports page showed a different "CSV" capitalisation in the
"Bookmarks" row ("Csv") compared to the other rows ("CSV").
This was due to a referece to a translation string that does not exist,
`bookmarks.csv`, defaulting to the key's last segment in title case.
This issue was introduced in commit dcd86204 (PR #14956).

* Add honeypot fields to limit non-specialized spam
Add two honeypot fields: a fake website input and a fake password confirmation
one. The label/placeholder/aria-label tells not to fill them, and they are
hidden in CSS, so legitimate users should not fall into these.
This should cut down on some non-Mastodon-specific spambots.

There are edge cases where requests to certain hosts timeout when
using the vanilla HTTP.rb gem, which the goldfinger gem uses. Now
that we no longer need to support OStatus servers, webfinger logic
is so simple that there is no point encapsulating it in a gem, so
we can just use our own Request class. With that, we benefit from
more robust timeout code and IPv4/IPv6 resolution.
Fix#14091
* feat: add possibility of adding WebAuthn security keys to use as 2FA
This adds a basic UI for enabling WebAuthn 2FA. We did a little refactor
to the Settings page for editing the 2FA methods – now it will list the
methods that are available to the user (TOTP and WebAuthn) and from
there they'll be able to add or remove any of them.
Also, it's worth mentioning that for enabling WebAuthn it's required to
have TOTP enabled, so the first time that you go to the 2FA Settings
page, you'll be asked to set it up.
This work was inspired by the one donde by Github in their platform, and
despite it could be approached in different ways, we decided to go with
this one given that we feel that this gives a great UX.

* feat: add request for WebAuthn as second factor at login if enabled
This commits adds the feature for using WebAuthn as a second factor for
login when enabled.
If users have WebAuthn enabled, now a page requesting for the use of a
WebAuthn credential for log in will appear, although a link redirecting
to the old page for logging in using a two-factor code will also be
present.

* feat: disable WebAuthn when an Admin disables 2FA for a user
Co-authored-by: Facundo Padula <facundo.padula@cedarcode.com>
* feat: remove ability to disable TOTP leaving only WebAuthn as 2FA
Following examples form other platforms like Github, we decided to make
Webauthn 2FA secondary to 2FA with TOTP, so that we removed the
possibility of removing TOTP authentication only, leaving users with
just WEbAuthn as 2FA. Instead, users will have to click on 'Disable 2FA'
in order to remove second factor auth.
The reason for WebAuthn being secondary to TOPT is that in that way,
users will still be able to log in using their code from their phone's
application if they don't have their security keys with them – or maybe
even lost them.
* We had to change a little the flow for setting up TOTP, given that now
it's possible to setting up again if you already had TOTP, in order to
let users modify their authenticator app – given that now it's not
possible for them to disable TOTP and set it up again with another
authenticator app.
So, basically, now instead of storing the new `otp_secret` in the
user, we store it in the session until the process of set up is
finished.
This was because, as it was before, when users clicked on 'Edit' in
the new two-factor methods lists page, but then went back without
finishing the flow, their `otp_secret` had been changed therefore
invalidating their previous authenticator app, making them unable to
log in again using TOTP.

This commits fixes that.
* refactor: avoid having the webauthn gem locked to a specific version
* refactor: use symbols for routes without '/'
* refactor: avoid sending webauthn disabled email when 2FA is disabled
When an admins disable 2FA for users, we were sending two mails
to them, one notifying that 2FA was disabled and the other to notify
that WebAuthn was disabled.
As the second one is redundant since the first email includes it, we can
remove it and send just one email to users.

used for anything except the default value of 36px.
Dropped CSS rules that were always overriden, and defaulted to 36px width

Also removed a `margin-bottom` rule that wasn't needed due to the
margins of surrounding elements.

* Fix “Email changed” notification sometimes having wrong e-mail
Fixes#6778
The root of the issue is that `send_devise_notification` was called before
the changes were properly commited to the database, causing the mailer to
pick previous values if running too early.
Devise's documentation provides guidance on how to handle that[1][2], however,
I have found it to not be working, as the following happens, in that order:
- `send_devise_notification` is called for the `email_changed` notification.
In that case, `changed?` is false and `saved_changes?` is true, so
if we use the former, we have the same issue.
- the `after_commit` hook is called
- `send_devise_notification` is called for the `confirmation_instructions`
notification.
In that case, `changed?` is still false, and `saved_changes?` still true,
so if we use the latter, that second notification email is simply not
going to be sent (as we would be queuing the notification *after*
executing the after_commit hook).
This is because it may be called from either an `after_update` or
`after_commit` hook, the difference not being a call to `save` but the
transaction actually being committed to the database. This may arguably
be a bug in Devise, or Devise's notification.
The proposed workaround is inspired by Devise's documentation but checks
whether a transaction is open to make the call whether to immediately
send the notification or defer it to the `after_commit` hook.

* Fix cases when sending notifications without changing the model
* Defer sending if and only if in transaction including current record
This commit redesign the polls and increases characters limit for the
options from 25 to 50 characters, giving pollsters more freedom.
Summarizing, the redesign is making the polls more adaptive for upcoming
changes to the options characters limit: the bar, or a "chart", is now
displayed separately from the option itself; vote check mark is moved
next to the option text, making the percentages take less space. Option
lengths are taken into account and text is wrapped to multiple lines
if necessary to avoid overflow.
If the “Why do you want to join?” textarea is left empty and the entered params
do not validate, the textarea isn't shown again, unlike other fields.
This commit fixes that by populating an empty `UserInviteRequest` when needed.
This adds "Show thread" button to the status view which is used in

This commit:
- Refactors centered text blocks currently used for placeholders
for empty tables and puts styles for it in separate class -
.centered-text, simply aliasing text-align: center. Which is
furtherly used in this commit.
- Improves applications settings page to use heading actions, moving
"New application" button there, and displaying placeholder "You
have no applications" in place of empty table.
- Improves custom emoji settings page to use heading action
for "Upload" button, making it more easily accessible without
need to scroll through all of the emojis.
- Improves email domain blocks settings page, moving "Add new" to the
heading actions and using placeholder "No e-mail domains currently
blacklisted" instead of showing empty table.
Current name - page_heading_actions is long and hard to remember,
this commit shortens it to just heading_actions, which is way more
easier to remember and write, it's logical too.
When you have many filters, it may be hard for you to reach the button
to create yet another one. This commit moves creation button to the
heading, leaving the page just for the list.
On the other hand, when there are no filters, page looks kind of
strange with the empty table. So text stating obvious fact that user
has no filters was added in this commit too.
Closes#11020Closes#12790
This commit adds promotional notice on appearance settings about
translation project if any other locale than English is used. It
allows users to learn and contribute translations to Mastodon.
Step ahead, in this commit one unusual string is added - link to a
guide. By default it refers to Crowdin project itself, but if any of
Mastodon localization teams established their own guide, they can
refer it. Or, if Crowdin supports localized domain for language, it
can also be put there (e.g. https://fr.crowdin.com/...).
Currently the page re-uses strings from other contexts which doesn't fit
very well - strings incorrectly lowercase-d and pluralized, when they
don't need to be, because it's a table.
This commit changes page to re-use accounts.posts_tab_heading for toots,
and admin.accounts for "Following" and "Follows". This all should look
more aesthetically pleasing.
* Move resolved button to the heading
This is one of the commits on improving overall reports page structure.
It changes where resolved button is located, moving it to the heading,
right next to the "Report #n" header, so-called "hot-place" to look at.
To accomplish this we have to declare one more content variable, change
admin dashboard template to respect it and CSS files for minor styling,
so buttons are inlined and centrally aligned according to the heading.
* Move actions buttons below the report table
I believe that actions to react on report should not be located at the
top of the page, instead they should be either after the table or
reporter's comment. This is just a logical sign that you should not
react to the report without reading all the details first.
Pluralize function from Rails framework does not work with other
languages than English, moreover it does not even work properly with
English [1]. Not that the latest applies to this context, it's just
a sign that we best to avoid this function, especially when there are
more reliable ways.
This commit changes how reports pages generated in order to avoid usage
of pluralize function, replacing it with default translation function,
called with given counter. On top of that, we have to make strings
pluralizable, so have to change locale files.

This commit changes how doorkeeper.applications.help.native_redirect_uri
string is being formatted to use <code> tag for native_redirect_uri
placeholder. This makes the URI look more distinguishable.
Before this moment relationships managing page was using strings from
other context - from counters, but in order for translators to be able
to translate it relatively to the page, it must use separate strings.
I've split the strings for "Following" and "Followers" and put them to
"relationships" keyset in localization file. This should solve this
issue.
Fixes#10863
Currently notifications page seems a bit cluttered with no clear
separation between e-mail and filtering settings. This commit tries to
address them by adding clear separation with headers, hints and removing
continuously reused texts for events checkboxes.
On mobile, batch actions are hidden from the settings/admin interface,
but there are several places those actions can only be performed through
batch actions.
This may not look great, but at least it makes the actions available again.

Fix#271
Add back the `GET /api/v1/trends` API with the caveat that it does
not return tags that have not been allowed to trend by the staff.
When a hashtag begins to trend (internally) and that hashtag has
not been previously reviewed by the staff, the staff is notified.
The new admin UI for hashtags allows filtering hashtags by where
they are used (e.g. in the profile directory), whether they have
been reviewed or are pending reviewal, they show by how many people
the hashtag is used in the directory, how many people used it
today, how many statuses with it have been created today, and it
allows fixing the name of the hashtag to make it more readable.
The disallowed hashtags feature has been reworked. It is now
controlled from the admin UI for hashtags instead of from
the file `config/settings.yml`
Allow access to account settings, 2FA, authorized applications, and
account deletions to unconfirmed and pending users, as well as
users who had their accounts disabled. Suspended users cannot update
their e-mail or password or delete their account.
Display account status on account settings page, for example, when
an account is frozen, limited, unconfirmed or pending review.
After sign up, login users straight away and show a simple page that
tells them the status of their account with links to account settings
and logout, to reduce onboarding friction and allow users to correct
wrongly typed e-mail addresses.
Move the final sign-up step of SSO integrations to be the same
as above to reduce code duplication.
