Browsers are phasing out X-XSS-Protection, but Safari and IE still support it.

Fixes #17297

* Fix error-prone SQL queries in Account search

While this code seems to not present an actual vulnerability, one could
easily be introduced by mistake due to how the query is built.

This PR parameterises the `to_tsquery` input to make the query more robust.

* Harden code for Status#tagged_with_all and Status#tagged_with_none

Those two scopes aren't used in a way that could be vulnerable to an SQL
injection, but keeping them unchanged might be a hazard.

* Remove unneeded spaces surrounding tsquery term

* Please CodeClimate

* Move advanced_search_for SQL template to its own function

This avoids one level of indentation while making clearer that the SQL template
isn't build from all the dynamic parameters of advanced_search_for.

* Add tests covering tagged_with, tagged_with_all and tagged_with_none

* Rewrite tagged_with_none to avoid multiple joins and make it more robust

* Remove obsolete brakeman warnings

* Revert "Remove unneeded spaces surrounding tsquery term"

The two queries are not strictly equivalent.

This reverts commit 86f16c53.

Some bundle options are saved as global user config and not project local.
Specially, `deployment` must be saved as local config to be run on copied environment

* Build container image by GitHub Actions

* Trigger docker build only pushed to main branch

* Tweak tagging imgae

- "edge" is the main branch
- "latest" is the tagged latest release

- populate the database with some data when testing migrations
- try both one-step and two-step migrations (`SKIP_POST_DEPLOYMENT_MIGRATIONS`)

* Fix some old migration scripts

* Fix edge case in two-step migration from older releases

Under certain conditions, files fetched from remotes trigger an error when
being uploaded using OpenStack Swift. This is because in some cases, the
remote server will not return a content-length, so our ResponseWithLimitAdapter
will hold a `nil` value for `#size`, which will lead to an invalid value
for the Content-Length header of the Swift API call.

This commit fixes that by taking the size from the actually-downloaded file
size rather than the upstream-provided Content-Length header value.

For some reason, some misconfigured servers return an empty document when
queried over webfinger. Since an empty document does not lead to a parse
error, the error is not caught properly and triggers uncaught exceptions
later on.

This PR fixes that by immediately erroring out with `Webfinger::Error` on
getting an empty response.

Up until now, we have used Devise's Rememberable mechanism to re-log users
after the end of their browser sessions. This mechanism relies on a signed
cookie containing a token. That token was stored on the user's record,
meaning it was shared across all logged in browsers, meaning truly revoking
a browser's ability to auto-log-in involves revoking the token itself, and
revoking access from *all* logged-in browsers.

We had a session mechanism that dynamically checks whether a user's session
has been disabled, and would log out the user if so. However, this would only
clear a session being actively used, and a new one could be respawned with
the `remember_user_token` cookie.

In practice, this caused two issues:
- sessions could be revived after being closed from /auth/edit (security issue)
- auto-log-in would be disabled for *all* browsers after logging out from one
  of them

This PR removes the `remember_token` mechanism and treats the `_session_id`
cookie/token as a browser-specific `remember_token`, fixing both issues.

hard-to-exploit) security vulnerabilities, addressing them in a test.

* Fix authentication failures after going halfway through a sign-in attempt

* Refactor `authenticate_with_sign_in_token` and `authenticate_with_two_factor` to make the two authentication steps more obvious

Fixes #16602

Fixes #16699

* Add tests

* Fix some link previews being incorrectly generated from different prior links

PR #12403 added a cache to avoid redundant queries when the OEmbed endpoint can
be guessed from the URL. This caching mechanism is not perfectly correct as
there is no guarantee that all pages from a given domain share the same
OEmbed provider endpoint.

This PR prevents the FetchOEmbedService from caching OEmbed endpoint that
cannot be generalized by replacing a fully-qualified URL from the endpoint's
parameters, greatly reducing the number of incorrect cached generalizations.

Fix regression from #16896

In order to work around https://github.com/mastodon/mastodon/issues/16895,
add a warning to .env.production.sample, and change the mastodon:setup rake
task to:
- output a warning if a variable will be interpreted differently by dotenv
  and docker-compose
- ensure the printed config is compatible with docker-compose

* Do not block existing users' emails on self-destruct

That is wasteful and unintuitive

* Do not close registrations when running tootctl self-destruct with --dry-run

* Close registrations on self-destruct regardless of known remote accounts

* Fix tootctl self-destruct not sending Deletes for recently-suspended accounts

* Suspend local users even if no remote account is known

* Do not show scary confirmation text if ran with --dry-run

* Add tests

* Fix serialization of followers/following counts when user hides their network
