* update gem, test pam authentication

* add description for test parameters

* fix inclusion of optional group

This also limits the statuses returned by API, but pagination is not
implemented in Web API yet. I still expect it brings user experience
better than making a user wait to fetch all ancestor statuses and flooding
the column with them.

* Admin: Show unconfirmed email address on account page

* Admin: Allow staff to change user email addresses

* ActionLog: On change_email, log current email address and new unconfirmed email address

* Enable updating additional account information from user preferences via rest api
Resolves #6553

* Pacify rubocop

* Decoerce incoming settings in UserSettingsDecorator

* Create user preferences hash directly from incoming credentials instead of going through ActionController::Parameters

* Clean up user preferences update

* Use ActiveModel::Type::Boolean instead of manually checking stringified number equivalence

Previously these returns 302 redirects instead of 403s, which meant posting links to admin pages in slack caused them to unfurl, rather than stay as a link. Additionally, require_admin! doesn't appear to be actively used, on require_staff!

* Implement Assignment of Reports (#6967)

* Change translation of admin.report.comment.label to "Report Comment" for clarity

As we'll soon add the ability for reports to have comments on them, this clarification makes sense.

* Implement notes for Reports

This enables moderators to leave comments about a report whilst they work on it

* Fix display of report moderation notes

* Allow reports to be reopened / marked as unresolved

* Redirect to reports listing upon resolution of report

* Implement "resolve with note" functionality

* Add inverse relationship for report notes

* Remove additional database querying when loading report notes

* Fix tests for reports

* Fix localisations for report notes / reports

Federate custom emojis with accounts

Note that this spec has a pending test about dots in the username,
because allowing it has been reverted for now.

to_s method of HTTP::Response keeps blocking while it receives the whole
content, no matter how it is big. This means it may waste time to receive
unacceptably large files. It may also consume memory and disk in the
process. This solves the inefficency by checking response length while
receiving.

HTTP connections must be explicitly closed in many cases, and letting
perform method close connections makes its callers less redundant and
prevent them from forgetting to close connections.

* request: in the event of failure, try other IPs (#6761)

In the case where a name has multiple A/AAAA records, we should
try subsequent records instead of immediately failing when we have a
failure on the first IP address.

This significantly improves delivery success when there are network
connectivity problems affecting only IPv4 or IPv6.

* fix method call style

* request_spec: adjust test case to use Addrinfo

* request: Request/open: move private addr check to within begin/rescue

* request_spec: add case to test failover, fix exception check

* Double Addrinfo.foreach so that it correctly yields instances

This is also implemented in Pawoo:
https://github.com/pixiv/mastodon/commit/ceafdbd1bbf30fe20a2a814df0f8cae429a4e9db

site_title is "Mastodon" by default configuration, and there is no need to
default site_title with site_hostname in InstanceHelper.

Previously the default locale was set by Localized concern for controllers,
but it was not enforced for mailers.

config is enforced throughout the application and an appropriate place to
set the default locale.

* Federate pinned statuses over ActivityPub

* Display pinned toots in web UI

Fix #6117

* Fix #2176: Federated reports

* UI for federated reports

* Add spec for ActivityPub Flag handler

* Add spec for ReportService

A complemental change for precompute_feed_service_spec.rb also fixes its
random failure which is caused by the Snowlake randomization of the order
of an original status and its reblog.

* Redesign landing page (again)

* Move login form in small version to the right column

* Display closed registrations message

* Add site setting for the hero image

* Fix test

* Increase spacing, maximum width, change call to action section

It was merge when it needed to be deep_merge. And added some tests

* Fix #201: Account archive download

* Export actor and private key in the archive

* Optimize BackupService

- Add conversation to cached associations of status, because
  somehow it was forgotten and is source of N+1 queries
- Explicitly call GC between batches of records being fetched
  (Model class allocations are the worst offender)
- Stream media files into the tar in 1MB chunks
  (Do not allocate media file (up to 8MB) as string into memory)
- Use #bytesize instead of #size to calculate file size for JSON
  (Fix FileOverflow error)
- Segment media into subfolders by status ID because apparently
  GIF-to-MP4 media are all named "media.mp4" for some reason

* Keep uniquely generated filename in Paperclip::GifTranscoder

* Ensure dumped files do not overwrite each other by maintaing directory partitions

* Give tar archives a good name

* Add scheduler to remove week-old backups

* Fix code style issue

* Added #link_header spec

* Added #call spec

* Delete spec of private methods

* Added call test case activitypub

The cache store is explicitly used by some specs, but they were not
isolated and therefore not reliable. This fixes the issue by clearing
the cache after each specs.

Some available languages lack translations for notification mails. Now it
tests for two languages which is certain to have required translations:
German and English.

German is the language the current project owner, Eugen Rochko speaks, and
providing English translations for new messages is de facto mandatory.

* Save metadata from video attachments, put correct dimensions into OG tags

* Add twitter:player for videos

* Fix code style and test

In cases where a URL has a trailing hyphen the FetchLinkCardService incorrectly removes the hyphen when it is parsed

The hyphen is not a reserved character in the URI spec https://tools.ietf.org/html/rfc3986#section-2.2
