Some content from app/javascript/packs/public.js has been split to
app/javascript/core/settings.js.
Translation strings for glitch-soc's keyword mutes were dropped.
Everything else was mostly “take both”.
Initially I thought there might be valid reasons for remote users to
have a different, unpredicted username format. However, I now realize
such a difference would be unusable and unexpected within Mastodon.
Fix#8058
To improve the way super tall or super ride images are treated, the
numbers remain the same, 1280x1280 and 400x400, but if an image
is less in one dimension than the other, the other can become larger

Conflicts were resolved by taking both versions for each change.
This means the two filter systems (glitch-soc's keyword mutes and tootsuite's
custom filters) are in place, which will be changed in a follow-up commit.
* Add more granular OAuth scopes
* Add human-readable descriptions of the new scopes
* Ensure new scopes look good on the app UI
* Add tests
* Group scopes in screen and color-code dangerous ones
* Fix wrong extra scope
* Re-add follow recommendations API
GET /api/v1/suggestions
Removed in 30f9e9e624 due to Neo4J
dependency. The algorithm uses triadic closures, takes into account
suspensions, blocks, mutes, domain blocks, excludes locked and moved
accounts, and prefers more recently updated accounts.
* Track interactions with people you don't follow
Replying to, favouriting and reblogging someone you're not following
will make them show up in follow recommendations. The interactions
have different weights:
- Replying is 1
- Favouriting is 10 (decidedly positive interaction, but private)
- Reblogging is 20
Following them, muting or blocking will remove them from the list,
obviously.
* Remove triadic closures, ensure potential friendships are trimmed
* Add keyword filtering
GET|POST /api/v1/filters
GET|PUT|DELETE /api/v1/filters/:id
- Irreversible filters can drop toots from home or notifications
- Other filters can hide toots through the client app
- Filters use a phrase valid in particular contexts, expiration
* Make sure expired filters don't get applied client-side
* Add missing API methods
* Remove "regex filter" from column settings
* Add tests
* Add test for FeedManager
* Add CustomFilter test
* Add UI for managing filters
* Add streaming API event to allow syncing filters
* Fix tests
If a status shows up in mentions because all keyword mutes that might
apply to it are marked as "don't apply to mentions", then it ought to
show up in the home feed also.
* Send rejections to followers when user hides domain they're on
* Use account domain blocks for "authorized followers" action
Replace soft-blocking (block & unblock) behaviour with follow rejection
* Split sync and async work of account domain blocking
Do not create domain block when removing followers by domain, that
is probably unexpected from the user's perspective.
* Adjust confirmation message for domain block
* yarn manage:translations
Also add an apply_to_mentions attribute on Glitch::KeywordMute, which is
used to calculate scope. Next up: additions to the test suite to
demonstrate how scoping works.

The above conflicts appear to be a text conflict introduced by
glitch-soc's additional level of columns (i.e. moving a bunch of columns

Commit 6c2344d4dd missed a change for
stream entry page. Instead of duplicating the change, redirect to account
status page. It would also help crawlers (of search engines, for example)
to understand a stream entry URL and its corresponding status URL points
to the same page.
* Add bio fields
- Fix#3211
- Fix#232
- Fix#121
* Display bio fields in web UI
* Fix output of links and missing fields
* Federate bio fields over ActivityPub as PropertyValue
* Improve how the fields are stored, add to Edit profile form
* Add rel=me to links in fields
Fix#121
Sidekiq sometimes throws errors for users that have more pinned items
than the allowed by the local instance. It should only validate the
number of pins for local accounts.
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.

The glitch flavour isn't yet pulling custom emoji data on its own (see

* 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.

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
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
Previously the default locale was set by Localized concern for controllers,

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

* Add site setting for the hero image
* Fix test
* Increase spacing, maximum width, change call to action section
* 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
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.
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
* Add full-text search for authorized statuses
- Search API will return statuses that match the query
- Only for logged in users
- Only if you are author of the status,
- Or you were mentioned in it
- Or you favourited or reblogged it
- Configuration over `ES_ENABLED`, `ES_HOST`, `ES_PORT`, `ES_PREFIX`
- Run `rails chewy:deploy` to create & populate index

* When must_be_following_dm is on, only notify if recipient dm'ed user
Currently, when must_be_following_dm is on, if a user sends a direct
message replying to any status from the recipient, the recipient gets a
notification. This should not be the case, as if the recipient posted
something publicly this can be used to spam their notifications.
* Refactor replied_to_status_is_direct_message?

* Adjust tests to new requirements
* Improve readability of mismatching_origin?/invalid_origin? methods
A change introduced in #6125 prevents
`Devise::Models::Confirmable#confirm` from being called for existing
users, which in turn leads to `email` not being set to
`unconfirmed_email`, breaking email updates. This also adds a test
that would've caught this issue.
* Don't normalize URLs in toots
URL normalization is ill-defined and may cause certain links to break.
* Change specs since we are not normalizing user-provided URLs
* Sanitize classlist properly
* Actually properly sanitize every class after the first
* Improve Formatter spec to check for multiple classes and non-space whitespace
* Add confirmation step for email changes
This adds a confirmation step for email changes of existing users.
Like the initial account confirmation, a confirmation link is sent
to the new address.
Additionally, a notification is sent to the existing address when
the change is initiated. This message includes instruction to reset
the password immediately or to contact the instance admin if the
change was not initiated by the account owner.
Fixes#3871
* Add review fixes
This commit also:
- exposes the local-only emoji so that it can be used in examples
- allows local_only to be set explicitly, i.e. for timeline filtering
specs
* Break out nested relationship API keys
This closes#5856 by restoring the existing behavior of the `muting`
and `following` keys (returning booleans rather than truthy or false).
It adds `showing_reblogs` and `muting_notifications` keys:
* `showing_reblogs` returns true if:
1. You've requested to follow the user, with reblogs shown, or
2. You are following the user, with reblogs shown.
* `muting_notifications` returns true if you have muted the user and
their notifications as well.
* Rubocop fix
* Fix pulling reblog/mute status from relationships
I could swear this had passed tests before, but apparently not.
Works now.
* More test fixes
Really, you'd expect this to be more straightforward.

with manually crafted text contents (title + URL)
* Extract html-url-finding logic into JsonLdHelper
* Fallback to id when url missing, extract supported object types
* Avoid sending explicit Undo->Announce when original deleted
* Do not forward a reply back to the server that sent it
* Deduplicate inboxes of rebloggers' followers for delete forwarding
* Adjust test
* Fix wrong class, bad SQL, wrong variable, outdated comment
* Allow hiding of reblogs from followed users
This adds a new entry to the account menu to allow users to hide
future reblogs from a user (and then if they've done that, to show
future reblogs instead).
This does not remove or add historical reblogs from/to the user's
timeline; it only affects new statuses.
The API for this operates by sending a "reblogs" key to the follow
endpoint. If this is sent when starting a new follow, it will be
respected from the beginning of the follow relationship (even if
the follow request must be approved by the followee). If this is
sent when a follow relationship already exists, it will simply
update the existing follow relationship. As with the notification
muting, this will now return an object ({reblogs: [true|false]}) or
false for each follow relationship when requesting relationship
information for an account. This should cause few issues due to an
object being truthy in many languages, but some modifications may
need to be made in pickier languages.
Database changes: adds a show_reblogs column (default true,
non-nullable) to the follows and follow_requests tables. Because
these are non-nullable, we use the existing MigrationHelpers to
perform this change without locking those tables, although the
tables are likely to be small anyway.
Tests included.

* Revert reblogs defaulting in argument, fix tests
It turns out we needed this for the same reason we needed it in muting:
if nil gets passed in somehow (most usually by an API client not passing
any value), we need to detect and handle it.
We could specify a default in the parameter and then also catch nil, but
there's no great reason to duplicate the default value.

- InviteCodeValidator is redundant because RegistrationsController
checks invite code validity
* Add admin setting to disable invites

StatusPolicy#account was renamed to StatusPolicy#current_account in
upstream. This commit renames the local-only changes to match and
augments the #show? policy spec with what we expect for local-only
toots.
=~ made sense when we were passing it through to a regex, but we're no
longer doing that: TagMatcher looks at individual tags and returns a
value that *looks* like what you get out of #=~ but really isn't that
meaningful. Probably a good idea to not subvert convention like this
and instead use a name with guessable intent.
It is reasonable to expect someone to enter #foo to mute hashtag #foo.
However, tags are recorded on statuses without the preceding #.
To adjust for this, we build a separate tag matcher and use
Tag::HASHTAG_RE to extract a hashtag from the hashtag syntax.

* i18n: Update Polish translation (for #5669) (#5673)
When given two regexps, Regexp.union preserves the options set (or not
set) on each regex; this meant that none of the multiline (m),
case-insensitivity (i), or extended syntax (x) options were set. Our
regexps are written expecting the m, i, and x options were set on all of
them, so we need to make sure that we preserve that behavior.
Note that this will only hide/show *future* reblogs by a user, and does
nothing to remove/add reblogs that are already in the timeline. I don't
think that's a particularly confusing behavior, and it's a lot easier
to implement (similar to mutes, I believe).
* Add a test for FollowRequest#authorize!
* Remove tests
There is no need to test
ActiveModel::Validations::ClassMethods#validates.
* Make an alias of destroy! as reject!
Instead of defining the method,
make an alias of destroy! as reject! because of reducing test.
Ditto for ending with \b.
Consider muting the phrase "(hot take)". I stipulate it is reasonable
to enter this with the default "match whole word" behavior. Under the
old behavior, this would be encoded as
\b\(hot\ take\)\b
However, if \b is before the first character in the string and the first
character in the string is not a word character, then the match will
fail. Ditto for after. In our example, "(" is not a word character, so
this will not match statuses containing "(hot take)", and that's a very
surprising behavior.
To address this, we only add leading and trailing \b to keywords that
start or end with word characters.
There are two motivations for this:
1. It looks like we're going to add other features that require
server-side storage (e.g. user notes).
2. Namespacing glitchsoc modifications is a good idea anyway: even if we
do not end up doing (1), if upstream introduces a keyword-mute feature
that also uses a "KeywordMute" model, we can avoid some merge
conflicts this way and work on the more interesting task of
choosing which implementation to use.
Word-boundary matching only works as intended in English and languages
that use similar word-breaking characters; it doesn't work so well in
(say) Japanese, Chinese, or Thai. It's unacceptable to have a feature
that doesn't work as intended for some languages. (Moreso especially
considering that it's likely that the largest contingent on the Mastodon
bit of the fediverse speaks Japanese.)
There are rules specified in Unicode TR29[1] for word-breaking across
all languages supported by Unicode, but the rules deliberately do not
cover all cases. In fact, TR29 states
For example, reliable detection of word boundaries in languages such
as Thai, Lao, Chinese, or Japanese requires the use of dictionary
lookup, analogous to English hyphenation.
So we aren't going to be able to make word detection work with regexes
within Mastodon (or glitchsoc). However, for a first pass (even if it's
kind of punting) we can allow the user to choose whether they want word
or substring detection and warn about the limitations of this
implementation in, say, docs.

This should eventually be accessible via the API and the web frontend,
but I find it easier to set up an editing interface using Rails
templates and the like. We can always take it out if it turns out we
don't need it.
A matcher object that builds a match from KeywordMute data and runs it
over text is, in my view, one of the easier ways to write examples for
this sort of thing.
Gist of the proposed keyword mute implementation:
Keyword mutes are represented server-side as one keyword per record.
For each account, there exists a keyword regex that is generated as one
big alternation of all keywords. This regex is cached (in Redis, I
guess) so we can quickly get it when filtering in FeedManager.
* Clean up reblog-tracking sets from FeedManager
Builds on #5419, with a few minor optimizations and cleanup of sets
after they are no longer needed.
* Update tests, fix multiply-reblogged case
Previously, we would have lost the fact that a given status was
reblogged if the displayed reblog of it was removed, now we don't.
Also added tests to make sure FeedManager#trim cleans up our reblog
tracking keys, fixed up FeedCleanupScheduler to use the right loop,
and fixed the test for it.
* Keep references to all reblogs of a status on home feed
When inserting reblog: Add to set of reblogs of this status on
the feed, if original status was present in the feed, add it to
that set as well.
When removing a reblog: Remove it from that set. Take random
remaining item from the set. If one exists, re-insert it into feed,
otherwise do not re-insert anything.
Fix#4210
* When original is removed, toss out reblog references
