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
* Add bell button
Fix#4890
* Remove duplicate type from post-deployment migration
* Fix legacy class type mappings
* Improve query performance with better index
* Fix validation
* Remove redundant index from notifications
* Check for and record reblog info atomically
Instead of using ZREVRANK to determine whether a reblog is a new reblog or not,
use ZADD's NX option to perform the check/addition option atomically.
* Replace ZREVRANK call with ZSCORE key which is more efficient
* Make tests a bit stricter
* Fix off-by-one
* Add database support for list show-reply preferences
* Add backend support to read and update list-specific show_replies settings
* Add basic UI to set list replies setting
* Add specs for list replies policy
* Switch "cycling" reply policy link to a set of radio inputs
* Capitalize replies_policy strings
* Change radio button design to be consistent with that of the directory explorer
Follow-up to #14359
In the case of limited toots, the receiver may not be explicitly part of the
audience. If a specific user's inbox URI was specified, it makes sense to
dereference the toot from the corresponding user, instead of trying to find
someone in the explicit audience.
* Fix not handling Undo on some activity types when they aren't inlined
When receiving an Undo for a non-inlined activity, try looking it up in
database using the URI. The queries are ad-hoc because we don't have a global
index of object URIs, and not all activity types are stored in database with
an index on their URI.
Announces are just statuses, and have an index on URIs, so this check can
be done efficiently.
Accepts cannot be handled at all because we don't record their URI at any
point.
Follows don't have an index on URI, but they have an index on the issuing
account, which should make such queries largely manageable.
Likes don't have an index on URI, they have an index on the issuing account,
but the number of favs per account may be very high, so I decided not to
handle that.
Blocks don't have an index on URI, but they have an index on the issuing
account, which should make such queries largely manageable.
In all cases, if an Undo could not be handled properly, we call `delete_later!`
because that does not require us to know more than the URI of the undone
property.
* Add tests
* Make newer blocks overwrite older ones
Allows re-synchronizing block info by re-blocking and un-blocking again
when the original Undo Block has been lost.
* Fix the local group's followers collection
* Fix to accept followed relayed_through_account
* Add local delivery to the group's followers
* Fix code style
* Revert "Add local delivery to the group's followers"
This reverts commit 3237effc19.
- Change audio files to not be stripped of metadata
- Automatically extract cover art from audio if it exists
- Add `thumbnail` parameter to `POST /api/v1/media`, `POST /api/v2/media` and `PUT /api/v1/media/:id`
- Add `icon` to represent it in attachments in ActivityPub
- Fix `preview_url` containing URL of missing missing image when there is no thumbnail instead of null
- Fix duration of audio not being displayed on public pages until the file is loaded
Thai does not separate words by spaces, so I figured out it should be
in 'reliable characters regexp' that denotes languages that do the same.

* Improve RSS entries for statuses
- Render polls in both accounts and tags serializers
- Refactor RSS serializers
- Change title preview to include ellipsis when truncated
- Change title preview to show CW instead of toot text
- Add tests
* Remove title from OEmbed serialization
Twitter doesn't serialize title either, and tihs allows us to move the
title formatting code to the RSS serializers.
* Fix PostgreSQL load when linking in announcements
Fixes#13245 by caching status lookups
Since statuses are supposed to be known already and we only
need their URLs and a few other things, caching them should
be fine.
Since it's only used by announcements so far, there won't
be much statuses to cache.
* Perform status lookup when saving announcements, not when rendering them
* Change EntityCache#status to fetch URLs instead of looking into the database
* Move announcement link lookup to publishing worker
* Address issues pointed out during review
Change `all_day` to be a visual client-side cue only

- update http gem to avoid errors
- update blurhash gem to avoid shared object loading error
- update goldfinger gem so the http gem could be updated
- update json gem to avoid warnings
* Fix wrong grouping in Twitter valid_url regex
* Add support for xmpp URIs
Fixes#9776
The difficult part is autolinking, because Twitter-text's extractor does
some pretty ad-hoc stuff to find things that “look like” URLs, and XMPP
URIs do not really match the assumptions of that lib, so it doesn't sound
wise to try to shoehorn it into the existing regex.
This is why I used a specific regex (very close, although slightly more
permissive than the RFC), and a specific scan function (a simplified version
of the generalized one from Twitter).
* Remove leading “xmpp:” from auto-linked text
* Remove “protocol” argument and return value, as only ActivityPub is supported
* Remove FetchRemoteAccountService, only use ActivityPub::FetchRemoteAccountService
* Fix tests
* Revert "Fix ignoring whole status because of one invalid hashtag (#11621)"
This reverts commit dff46b260b.
* Fix statuses being rejected because of invalid hashtag names
* Add spec for invalid hashtag names in statuses
* Add test for featured tags controller
This adds support for Event AP type in Mastodon. Events are converted
into toots by taking their title (AS name) and their URL (AP ID). Event
picture is also brought in if available.

* Revert "Relax characters that can be used in username (same as Application)"
This reverts commit 7e10a137b8.
* Delete display_name method
Some ActivityPub servers refuse to embed remote objects into their own
output. This is because they are not the authoritative source for these
objects, and as such embedding them is always a waste of space. The
follow request and follow models contain a URI, so this can be used to
match them.
Fetching statuses from all followed accounts at once takes too long
within Postgres. Fetching them one by one and merging in Ruby
could be a lot less resource-intensive
Because the query for dynamically fetching the home timeline is so
heavy, we can no longer offer it when the home timeline is missing

* Correctly reflect that follow requests weren't auto-accepted when local account is silenced
* Accept follow requests from user-muted accounts to avoid leaking mutes
The reason for unattaching media instead of removing it is to support
delete & redraft functionality, but remote or staff-removed statuses
will never be redrafted, so the media should be deleted immediately

* Remove poll validation for remote polls
* Add polls to public pages
* When updating the poll, update options just in case they were changed
* Fix public pages showing both poll and other media
* Fetch up to 5 replies when discovering a new remote status
This is used for resolving threads downwards. The originating
server must add a “replies” attributes with such replies for it to
be useful.
* Add some tests for ActivityPub::FetchRepliesWorker
* Add specs for ActivityPub::FetchRepliesService
* Serialize up to 5 public self-replies for ActivityPub notes
* Add specs for ActivityPub::NoteSerializer
* Move exponential backoff logic to a worker concern
* Fetch first page of paginated collections when fetching thread replies
* Add specs for paginated collections in replies
* Move Note replies serialization to a first CollectionPage
The collection isn't actually paginable yet as it has no id nor
a `next` field. This may come in another PR.
* Use pluck(:uri) instead of map(&:uri) to improve performances
* Fix fetching replies when they are in a CollectionPage
`::FetchRemoteAccountService` is not `ActivityPub::FetchRemoteAccountService`,
its second argument is the pre-fetched body. Passing `id: false` actually passed
a `Hash` as the prefetched body, instead of properly resolving unknown remote
accounts.
* Filter incoming Announce activities by relation to local activity
Reject if announcer is not followed by local accounts, and is not
from an enabled relay, and the object is not a local status
Follow-up to #10005
* Fix tests
Reject those from accounts with no local followers, from relays
that are not enabled, which do not address local accounts and are
not replies to accounts that do have local followers
* When self-boosting, embed original toot into Announce serialization
* Process unknown self-boosts from Announce object if it is more than an URI
* Add some self-boost specs
* Only serialize private toots in self-Announces

* Do not LDS-sign Follow, Accept, Reject, Undo, Block
* Do not use LDS for Create activities of private toots
* Minor cleanup
* Ignore unsigned activities instead of misattributing them
* Use status.distributable? instead of querying visibility directly

Fixes#9222
* Handle cases where user is nil in add_to_home and add_to_list
* Add hint for setting_aggregate_reblogs option
* Reword setting_aggregate_reblogs label
* Fix connect timeout not being enforced
The loop was catching the timeout exception that should stop execution, so the next IP would no longer be within a timed block, which led to requests taking much longer than 10 seconds.
* Use timeout on each IP attempt, but limit to 2 attempts
* Fix code style issue
* Do not break Request#perform if no block given
* Update method stub in spec for Request
* Move timeout inside the begin/rescue block
* Use Resolv::DNS with timeout of 1 to get IP addresses
* Update Request spec to stub Resolv::DNS instead of Addrinfo
* Fix Resolve::DNS stubs in Request spec
* Add silent column to mentions
* Save silent mentions in ActivityPub Create handler and optimize it
Move networking calls out of the database transaction
* Add "limited" visibility level masked as "private" in the API
Unlike DMs, limited statuses are pushed into home feeds. The access
control rules between direct and limited statuses is almost the same,
except for counter and conversation logic
* Ensure silent column is non-null, add spec
* Ensure filters don't check silent mentions for blocks/mutes
As those are "this person is also allowed to see" rather than "this
person is involved", therefore does not warrant filtering
* Clean up code
* Use Status#active_mentions to limit returned mentions
* Fix code style issues
* Use Status#active_mentions in Notification
And remove stream_entry eager-loading from Notification
* Downcase signed_headers string before building the signed string
The HTTP Signatures draft does not mandate the “headers” field to be downcased,
but mandates the header field names to be downcased in the signed string, which
means that prior to this patch, Mastodon could fail to process signatures from
some compliant clients. It also means that it would not actually check the
Digest of non-compliant clients that wouldn't use a lowercased Digest field
name.
Thankfully, I don't know of any such client.
* Revert "Remove dead code (#8919)"
This reverts commit a00ce8c92c.
* Restore time window checking, change it to 12 hours
By checking the Date header, we can prevent replaying old vulnerable
signatures. The focus is to prevent replaying old vulnerable requests
from software that has been fixed in the meantime, so a somewhat long
window should be fine and accounts for timezone misconfiguration.
* Escape users' URLs when formatting them
Fixes possible HTML injection
* Escape all string interpolations in Formatter class
Slightly improve performance by reducing class allocations
from repeated Formatter#encode calls
* Fix code style issues
Mention and emoji code may perform network calls, but does not need
to do that inside the database transaction. This may improve availability
of database connections when using pgBouncer in transaction mode.
* Add conversations API
* Add web UI for conversations
* Add test for conversations API
* Add tests for ConversationAccount
* Improve web UI
* Rename ConversationAccount to AccountConversation
* Remove conversations on block and mute
* Change last_status_id to be a denormalization of status_ids
* Add optimistic locking
* Changed list behaviour
I added the following line to the FeedManager (app/lib/feed_manager.rb) in the push_to_list function:
`return false if status.reply?`
Now all posts that are replies are filtered out, so that now only "genuine" posts are displayed in the list.
This is a first approach to solve issue #5916
* Update feed_manager.rb
As suggested by @Gargron
* Verify link ownership with rel="me"
* Add explanation about verification to UI
* Perform link verifications
* Add click-to-copy widget for verification HTML
* Redesign edit profile page
* Redesign forms
* Improve responsive design of settings pages
* Restore landing page sign-up form
* Fix typo
* Support <link> tags, add spec
* Fix links not being verified on first discovery and passive updates
* Add animate custom emoji param to embed pages
* Rename param, use it for avatars and gifs
* Fix issues pointed by codeclimate and breaking test
* Ignore brakeman warning
* If an Update is signed with known key, skip re-following procedure
Because it means the remote actor did *not* lose their database
* Add CLI method for rotating keys
bin/tootctl accounts rotate [USERNAME]
Generates a new RSA key per account and sends out an Update activity
signed with the old key.
* Key rotation: Space out Update fan-outs every 5 minutes per 1000 accounts
* Skip suspended accounts in key rotation
* Add default_settings class method to ScopedSettings
ScopedSettings was extended to use value of unscoped setting instead of
only using defaults set in config/settings.yml for selected settings.
This adds possibility for admins to set default values of users' settings,
for example default theme (as requested in #7092).
* Add ability to change an instance default theme
Closes#7092
If the input text is blank after preparation (only mention, or
only URL, or empty as in a media post), then use nil as language,
since it's OK to show to everyone.
Otherwise, always fall back to the server's default locale
* Re-add follow recommendations API
GET /api/v1/suggestions
Removed in 8efa081f21 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
If Mastodon accesses to the hidden service via transparent proxy, it's needed to avoid checking whether it's a private address, since `.onion` is resolved to a private address.
I was previously using the `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` to provide that function. However, I realized that using `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` is redundant, since this specification is always used with `ALLOW_ACCESS_TO_HIDDEN_SERVICE`. Therefore, I decided to integrate the setting of `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` into` ALLOW_ACCESS_TO_HIDDEN_SERVICE`.
* 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
* Do not accept ActivityPub follow requests from blocked user
Fix#7745
* Deliver auto-rejection immediately when follow-requested by blocked account
* Fix trailing whitespace
* Add preference to hide following/followers lists
- Public pages
- ActivityPub collections (does not return pages but does give total)
- REST API (unless it's your own) (does not federate)
Fix#6901
* Add preference
* Add delegation
* Fix issue
* Fix issue
When an ActivityPub Announce is processed and the boosted toot is not known,
fetch it on behalf of one of the booster's followers. This is to allow
fetching self-boosts of previously-unknown private toots.
If fetching on behalf of a user fails, try fetching it anonymously: the
selected follower of a boosting user may be banned by the boosted toot's
author.
* If an OStatus message contains nsfw hashtag, mark it as sensitive
Undo parts of #7048
* Put nsfw hashtag on OStatus messages if they have any media
* Fix code style issues
Same URI passed between follow request and follow, since they are
the same thing in ActivityPub. Local URIs are generated during
creation using UUIDs and are passed to serializers.
* Revert "Fixes/do not override timestamps (#7331)"
This reverts commit 581a5c9d29.
* Document Snowflake ID corner-case a bit more
Snowflake IDs are used for two purposes: making object identifiers harder to
guess and ensuring they are in chronological order. For this reason, they
are based on the `created_at` attribute of the object.
Unfortunately, inserting items with older snowflakes IDs will break the
assumption of consumers of the paging APIs that new items will always have
a greater identifier than the last seen one.
* Add `override_timestamps` virtual attribute to not correlate snowflake ID with created_at
* Do not override timestamps for incoming toots
* Remove every reference to override_timestamps
Statuses are now created with the announced publishing date
and are only pushed to timelines if that date is at most
6 hours earlier than the time at which it is processed.
* No need to re-require sidekiq plugins, they are required via Gemfile
* Add derailed_benchmarks tool, no need to require TTY gems in Gemfile
* Replace ruby-oembed with FetchOEmbedService
Reduce startup by 45382 allocated objects
* Remove preloaded JSON-LD in favour of caching HTTP responses
Reduce boot RAM by about 6 MiB
* Fix tests
* Fix test suite by stubbing out JSON-LD contexts
