Ref: cfa9b6e13a
This breaks compatibility with pre-2.3.0 Mastodon and older
software, but at the time of writing the network is >80% above
that version.
Compatibility broken only for toots with no text.
* 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
Old statuses and statuses from Pawoo, which runs a modified version of
Mastodon, may not have been marked sensitive even if spoiler text is
present.
Such statuses are still not marked sensitve if they are local or
arrived before version upgrade. Marking recently fetched remote status
sensitive contradicts the behavior.
Considering what people expected when they authored such statuses, this
change removes the sensitivity enforcement.
Do not touch statuses_count on accounts table when mass-destroying
statuses to reduce load when removing accounts, same for
reblogs_count and favourites_count
Do not count statuses with direct visibility in statuses_count

`ResolveAccountService` class [0].
ActivityPub accounts are identified using `@username` and `@domain` pair
instead of URI since #6842.

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.

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.
Media attachments are part of the association cache of statuses,
since they are presumed to be immutable. Unless this cache is
cleared manually, the statuses will continue to look like they
have media embedded.

* 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.

It turns out we needed this for the same reason we needed it in muting:

there's no great reason to duplicate the default value.

* If the DM responds to a toot by recipient, allow it through
* i18n: Update Polish translation (for #5669) (#5673)
* Work around Twidere and Tootdon bug
Tootdon and Twidere construct @user@domain handles from mentions in toots based
solely on the mention text and account URI's domain without performing any
webfinger call or retrieving account info from the Mastodon server.
As a result, when a remote user has WEB_DOMAIN ≠ LOCAL_DOMAIN, Twidere and
Tootdon will construct the mention as @user@WEB_DOMAIN. Now, this will usually
resolve to the correct account (since the recommended configuration is to have
WEB_DOMAIN perform webfinger redirections to LOCAL_DOMAIN) when processing
mentions, but won't do so when displaying them (as it does not go through the
whole account resolution at that time).
This change rewrites mentions to the resolved account, so that displaying the
mentions will work.
* Use lookbehind instead of non-capturing group in MENTION_RE
Indeed, substitutions with the previous regexp would erroneously eat any
preceding whitespace, which would lead to concatenated mentions in the
previous commit.
Note that users will “lose” up to one character space per mention for their
toots, as that regexp is also used to remove the domain-part of mentioned
users for character counting purposes, and it also erroneously removed the
preceding character if it was a space.
* Resolve remote accounts when mentioned even if they are already known
This commit reduces the risk of not having up-to-date public key or protocol
information for a remote account, which is required to deliver toots
(especially direct messages).
* Do not add mentions in private messages for remote users we cannot deliver to
Mastodon does not deliver private and direct toots to OStatus users, as there
is no guarantee the remote software understands the toot's privacy. However,
users currently do not get any feedback on it (Mastodon won't attempt delivery,
but the toot will be displayed exactly the same way to the user).
This change introduces *some* feedback by not processing mentions that are
not going to be delivered. A long-term solution is still needed to have
delivery receipts or at least some better indication of what is going on, but
at least an user can see *something* is up.
This commit reduces the risk of not having up-to-date public key or protocol
information for a remote account, which is required to deliver toots
(especially direct messages).
Specifically, this fixes status length calculation to be same as JS side.
BTW, since this pattern used in not only preview card fetching, we
should extract it (with twitter-regex?) and write tests I think.
Remote ActivityPub users that have never been known as OStatus users
(whether or not they support it) will not have a “remote_url” attribute
set. In case they reside on an instance with WEB_DOMAIN ≠ LOCAL_DOMAIN,
the current check did rely on “remote_url” to verify the user's domain.
* If OEmbed response doesn't have a required property `type`, ignore it.
e.g. `NoMethodError: undefined method 'type' for ...`
* If we failed to detect encoding, fallback to default behavior of Nokogiri.
e.g. `KeyError: key not found: :encoding`
- Rename Mastodon::TimestampIds into Mastodon::Snowflake for clarity

* Improve error handling on LinkCrawlWorker
* Ignore TimeoutError and InvalidURIError too
* Record errors to debug log
* Enable dead job queue on LinkCrawlWorker
Since most of acceptable errors were already ignored, only our side issue should go to dead job queue.
* Ignore all http gem errors
The whole point of verified_webfinger? is to check the WebFinger-discoverable
URI maps back to the known author URI. This was not actually verified if the
first Webfinger request was not a redirection.
* Use non-serial IDs
This change makes a number of nontrivial tweaks to the data model in
Mastodon:
* All IDs are now 8 byte integers (rather than mixed 4- and 8-byte)
* IDs are now assigned as:
* Top 6 bytes: millisecond-resolution time from epoch
* Bottom 2 bytes: serial (within the millisecond) sequence number
* See /lib/tasks/db.rake's `define_timestamp_id` for details, but
note that the purpose of these changes is to make it difficult to
determine the number of objects in a table from the ID of any
object.
* The Redis sorted set used for the feed will have values used to look
up toots, rather than scores. This is almost always the same as the
existing behavior, except in the case of boosted toots. This change
was made because Redis stores scores as double-precision floats,
which cannot store the new ID format exactly. Note that this doesn't
cause problems with sorting/pagination, because ZREVRANGEBYSCORE
sorts lexicographically when scores are tied. (This will still cause
sorting issues when the ID gains a new significant digit, but that's
extraordinarily uncommon.)
Note a couple of tradeoffs have been made in this commit:
* lib/tasks/db.rake is used to enforce many/most column constraints,
because this commit seems likely to take a while to bring upstream.
Enforcing a post-migrate hook is an easier way to maintain the code
in the interim.
* Boosted toots will appear in the timeline as many times as they have
been boosted. This is a tradeoff due to the way the feed is saved in
Redis at the moment, but will be handled by a future commit.
This would effectively close Mastodon's #1059, as it is a
snowflake-like system of generating IDs. However, given how involved
the changes were simply within Mastodon, it may have unexpected
interactions with some clients, if they store IDs as doubles
(or as 4-byte integers). This was a problem that Twitter ran into with
their "snowflake" transition, particularly in JavaScript clients that
treated IDs as JS integers, rather than strings. It therefore would be
useful to test these changes at least in the web interface and popular
clients before pushing them to all users.
* Fix JavaScript interface with long IDs
Somewhat predictably, the JS interface handled IDs as numbers, which in
JS are IEEE double-precision floats. This loses some precision when
working with numbers as large as those generated by the new ID scheme,
so we instead handle them here as strings. This is relatively simple,
and doesn't appear to have caused any problems, but should definitely
be tested more thoroughly than the built-in tests. Several days of use
appear to support this working properly.
BREAKING CHANGE:
The major(!) change here is that IDs are now returned as strings by the
REST endpoints, rather than as integers. In practice, relatively few
changes were required to make the existing JS UI work with this change,
but it will likely hit API clients pretty hard: it's an entirely
different type to consume. (The one API client I tested, Tusky, handles
this with no problems, however.)
Twitter ran into this issue when introducing Snowflake IDs, and decided
to instead introduce an `id_str` field in JSON responses. I have opted
to *not* do that, and instead force all IDs to 64-bit integers
represented by strings in one go. (I believe Twitter exacerbated their
problem by rolling out the changes three times: once for statuses, once
for DMs, and once for user IDs, as well as by leaving an integer ID
value in JSON. As they said, "If you’re using the `id` field with JSON
in a Javascript-related language, there is a very high likelihood that
the integers will be silently munged by Javascript interpreters. In most
cases, this will result in behavior such as being unable to load or
delete a specific direct message, because the ID you're sending to the
API is different than the actual identifier associated with the
message." [1]) However, given that this is a significant change for API
users, alternatives or a transition time may be appropriate.
1: https://blog.twitter.com/developer/en_us/a/2011/direct-messages-going-snowflake-on-sep-30-2011.html
* Restructure feed pushes/unpushes
This was necessary because the previous behavior used Redis zset scores
to identify statuses, but those are IEEE double-precision floats, so we
can't actually use them to identify all 64-bit IDs. However, it leaves
the code in a much better state for refactoring reblog handling /
coalescing.
Feed-management code has been consolidated in FeedManager, including:
* BatchedRemoveStatusService no longer directly manipulates feed zsets
* RemoveStatusService no longer directly manipulates feed zsets
* PrecomputeFeedService has moved its logic to FeedManager#populate_feed
(PrecomputeFeedService largely made lots of calls to FeedManager, but
didn't follow the normal adding-to-feed process.)
This has the effect of unifying all of the feed push/unpush logic in
FeedManager, making it much more tractable to update it in the future.
Due to some additional checks that must be made during, for example,
batch status removals, some Redis pipelining has been removed. It does
not appear that this should cause significantly increased load, but if
necessary, some optimizations are possible in batch cases. These were
omitted in the pursuit of simplicity, but a batch_push and batch_unpush
would be possible in the future.
Tests were added to verify that pushes happen under expected conditions,
and to verify reblog behavior (both on pushing and unpushing). In the
case of unpushing, this includes testing behavior that currently leads
to confusion such as Mastodon's #2817, but this codifies that the
behavior is currently expected.
* Rubocop fixes
I could swear I made these changes already, but I must have lost them
somewhere along the line.
* Address review comments
This addresses the first two comments from review of this feature:
https://github.com/tootsuite/mastodon/pull/4801#discussion_r139336735https://github.com/tootsuite/mastodon/pull/4801#discussion_r139336931
This adds an optional argument to FeedManager#key, the subtype of feed
key to generate. It also tests to ensure that FeedManager's settings are
such that reblogs won't be tracked forever.
* Hardcode IdToBigints migration columns
This addresses a comment during review:
https://github.com/tootsuite/mastodon/pull/4801#discussion_r139337452
This means we'll need to make sure that all _id columns going forward
are bigints, but that should happen automatically in most cases.
* Additional fixes for stringified IDs in JSON
These should be the last two. These were identified using eslint to try
to identify any plain casts to JavaScript numbers. (Some such casts are
legitimate, but these were not.)
Adding the following to .eslintrc.yml will identify casts to numbers:
~~~
no-restricted-syntax:
- warn
- selector: UnaryExpression[operator='+'] > :not(Literal)
message: Avoid the use of unary +
- selector: CallExpression[callee.name='Number']
message: Casting with Number() may coerce string IDs to numbers
~~~
The remaining three casts appear legitimate: two casts to array indices,
one in a server to turn an environment variable into a number.
* Only implement timestamp IDs for Status IDs
Per discussion in #4801, this is only being merged in for Status IDs at
this point. We do this in a migration, as there is no longer use for
a post-migration hook. We keep the initialization of the timestamp_id
function as a Rake task, as it is also needed after db:schema:load (as
db/schema.rb doesn't store Postgres functions).
* Change internal streaming payloads to stringified IDs as well
This is equivalent to 591a9af356faf2d5c7e66e3ec715502796c875cd from
#5019, with an extra change for the addition to FeedManager#unpush.
* Ensure we have a status_id_seq sequence
Apparently this is not a given when specifying a custom ID function,
so now we ensure it gets created. This uses the generic version of this
function to more easily support adding additional tables with timestamp
IDs in the future, although it would be possible to cut this down to a
less generic version if necessary. It is only run during db:schema:load
or the relevant migration, so the overhead is extraordinarily minimal.
* Transition reblogs to new Redis format
This provides a one-way migration to transition old Redis reblog entries
into the new format, with a separate tracking entry for reblogs.
It is not invertible because doing so could (if timestamp IDs are used)
require a database query for each status in each users' feed, which is
likely to be a significant toll on major instances.
* Address review comments from @akihikodaki
No functional changes.
* Additional review changes
* Heredoc cleanup
* Run db:schema:load hooks for test in development
This matches the behavior in Rails'
ActiveRecord::Tasks::DatabaseTasks.each_current_configuration, which
would otherwise break `rake db:setup` in development.
It also moves some functionality out to a library, which will be a good
place to put additional related functionality in the near future.
Additionally, ActivityPub::FetchRemoteStatusService no longer parses
activities.
OStatus::Activity::Creation no longer delegates to ActivityPub because
the provided ActivityPub representations are not signed while OStatus
representations are.
If the signature could not be verified and the webfinger of the account
was last retrieved longer than the cache period, try re-resolving the
account and then attempting to verify the signature again
- Previously they wouldn't receive it unless they were author's
followers
- Skip unpush from public/hashtag timelines if status wasn't
public in the first place
* Fix JavaScript interface with long IDs
Somewhat predictably, the JS interface handled IDs as numbers, which in
JS are IEEE double-precision floats. This loses some precision when
working with numbers as large as those generated by the new ID scheme,
so we instead handle them here as strings. This is relatively simple,
and doesn't appear to have caused any problems, but should definitely
be tested more thoroughly than the built-in tests. Several days of use
appear to support this working properly.

This was made to make a test a bit less flakey, but has nothing to
do with this branch.

Per

we need these changes to send deleted status IDs as strings, not
integers.
* Support OpenGraph video embeds

a keypair change is indicative of whole user (or instance) data loss. In this
situation, the “new” user might be different, and almost certainly has an empty
followers list. In this case, Mastodon instances will disagree on follower
lists, leading to unreliable delivery and “shadow followers”, that is users
believed by a remote instance to be followers, without the affected user
knowing.
Drawbacks of this change are:
1. If an user legitimately changes public key for some reason without losing
data (not possible in Mastodon at the moment), they will have their remote
followers unsubscribed/re-subscribed needlessly.
2. Depending of the number of remote followers, this may generate quite some
traffic.
3. If the user change is an attempt at usurpation, the remote followers will
unknowingly follow the usurper. Note that this is *not* a change of
behavior, Mastodon already behaves like that, although delivery might be
unreliable, and the usurper would not have known the former user's
followers.
* Rename ResubscribeWorker to RefollowWorker
* Process followers in batches
When a new user confirms their e-mail, bootstrap their home timeline
by automatically following a set of accounts. By default, all local
admin accounts (that are unlocked). Can be customized by new admin
setting (comma-separated usernames, local and unlocked only)
- Fix assumption that `url` is always a string. Handle it if it's an
array of strings, array of objects, object, or string, both for
accounts and for objects
- `sharedInbox` is actually supposed to be under `endpoints`, handle
both cases and adjust the serializer
* Make "unfollow" undo pending outgoing follow request too
* Add cancel button to web UI when awaiting follow request approval
* Make the hourglass button do the cancelling
Using _: property names is discouraged, as in the future,
canonicalization may throw an error when encountering that instead
of discarding it silently like it does now.
We are defining some ActivityStreams properties which we expect
to land in ActivityStreams eventually, to ensure that future versions
of Mastodon will remain compatible with this even once that happens.
Those would be `locked`, `sensitive` and `Hashtag`
We are defining a custom context inline for some properties which we
do not expect to land in any other context. `atomUri`, `inReplyToAtomUri`
and `conversation` are part of the custom defined OStatus context.
* Make PreviewCard records reuseable between statuses
**Warning!** Migration truncates preview_cards tablec
* Allow a wider thumbnail for link preview, display it in horizontal layout (#4648)
* Delete preview cards files before truncating
* Rename old table instead of truncating it
* Add mastodon:maintenance:remove_deprecated_preview_cards
* Ignore deprecated_preview_cards in schema definition
* Fix null behaviour
* Guarantee Subscription service first account has proper URL details
Subscription Service potentially could break if the first user suspended
themselves, creating a situation where the urls that populate throughout
subscription service's PuSH request would cause the remote API to throw 503 errors.
Guaranteeing that the first account picked is not suspended prevents this problem.
* Fix style issue
Requires moving Atom rendering from DistributionWorker (where
`stream_entry.status` is already nil) to inline (where
`stream_entry.status.destroyed?` is true) and distributing that.
Unfortunately, such XML renderings can no longer be easily chained
together into one payload of n items.
* Add handling of Linked Data Signatures in payloads
* Add a way to sign JSON, fix canonicalization of signature options
* Fix signatureValue encoding, send out signed JSON when distributing
* Add missing security context
* Process Create / Announce activity in FetchRemoteStatusService
* Use activity URL in ActivityPub for reblogs
* Redirect to the original status on StatusesController#show
* Ignore empty response in ActivityPub::FetchRemoteStatusService
This fixes `NoMethodError: undefined method `[]' for nil:NilClass` error.
* Check json.nil? in JsonLdHelper#supported_context?
* Fallback to OStatus in FetchAtomService
* Skip activity+json link if that activity is Person without inbox
* If unsupported activity was detected and all other URLs failed, retry with ActivityPub-less Accept header
* Allow mention to OStatus account in ActivityPub
* Don't update profile with inbox-less Person object
- Tries to avoid performing HTTP request if the keyId is an actor URI
- Likewise if the URI is a fragment URI on top of actor URI
- Resolves public key, returns owner if the owner links back to the key
* ActivityPub migration procedure
Once one account is detected as going from OStatus to ActivityPub,
invalidate WebFinger cache for other accounts from the same domain
* Unsubscribe from PuSH updates once we receive an ActivityPub payload
* Re-subscribe to PuSH unless already unsubscribed, regardless of protocol
* Add ActivityPub inbox
* Handle ActivityPub deletes
* Handle ActivityPub creates
* Handle ActivityPub announces
* Stubs for handling all activities that need to be handled
* Add ActivityPub actor resolving
* Handle conversation URI passing in ActivityPub
* Handle content language in ActivityPub
* Send accept header when fetching actor, handle JSON parse errors
* Test for ActivityPub::FetchRemoteAccountService
* Handle public key and icon/image when embedded/as array/as resolvable URI
* Implement ActivityPub::FetchRemoteStatusService
* Add stubs for more interactions
* Undo activities implemented

* Hook up ActivityPub to ResolveRemoteAccountService, handle
Update Account activities
* Add fragment IDs to all transient activity serializers
* Add tests and fixes
* Add stubs for missing tests
* Add more tests
* Add more tests
* Allow domain blocks to reject media without silencing or suspending
* Fix typo
* Hide 'Reject media' button when superfluous, instead of disabling it
* Properly hide 'reject media' checkbox on page load if needed
This may happen when resubmitting the domain block form after an error.
* Don't ask whether undoing a media-only block should be retroactive
* Rename :media_only block to :noop
* Display :noop block as None in frontend, allow blocks that do nothing
* Remove 'coding' line auto-added by emacs
* Do not raise unretryable exceptions in ResolveRemoteAccountService
* Removed fatal exceptions from ResolveRemoteAccountService
Exceptions that cannot be retried should not be raised. New exception
class for those that can be retried (Mastodon::UnexpectedResponseError)
* Refactor ResolveRemoteAccountService
* Remove trailing whitespace
* Use redis locks around critical ResolveRemoteAccountService code
* Add test for race condition of lock
* Wrap methods of ProcessFeedService::ProcessEntry in classes
This is a change same with 425acecfdb, except
that it has the following changes:
* Revert irrelevant change in find_or_create_conversation
* Fix error handling for RemoteActivity
* Introduce Ostatus name space
* Add dependency on idn-ruby to speed up URI normalization
* Use normalized_host instead of normalize.host when applicable
When we are only interested in the normalized host, calling normalized_host
avoids normalizing the other components of the URI as well as creating a
new object
* Add Request class with HTTP signature generator
Spec: https://tools.ietf.org/html/draft-cavage-http-signatures-06
* Add HTTP signature verification concern
* Add test for SignatureVerification concern
* Add basic test for Request class
* Make PuSH subscribe/unsubscribe requests use new Request class
Accidentally fix lease_seconds not being set and sent properly, and
change the new minimum subscription duration to 1 day
* Make all PuSH workers use new Request class
* Make Salmon sender use new Request class
* Make FetchLinkService use new Request class
* Make FetchAtomService use the new Request class
* Make Remotable use the new Request class
* Make ResolveRemoteAccountService use the new Request class
* Add more tests
* Allow +-30 seconds window for signed request to remain valid
* Disable time window validation for signed requests, restore 7 days
as PuSH subscription duration (which was previous default due to a bug)
- Use unicode when selecting emoji through picker
- Convert shortcodes to unicode when storing text input server-side
- Do not convert shortcodes in JS anymore
* Specs for language detection
* Use CharlockHolmes instead of NKF
* Correct mistakes
* Correct style
* Set hint_enc instead of falling back and strip_tags
* Improve specs
* Add dependencies
Ensure the only allowed author of top-level entries in feed is the person
the feed belongs to (a verified user). Ensure delete events only apply
if the deleted item belonged to that user.
The classes using Status.as_home_timeline, namely Feed and
PrecomputeFeedService are expected to filter direct statuses as
FanOutWriteService does, but their filtering were incomplete or missing.
This commit solves the problem by filtering direct statuses in
as_home_timeline as the other similar methods such as as_public_timeline
does.
* Make Pubsubhubbub::DistributionWorker handle both single stream entry
arguments, as well as arrays of stream entries
* Add BatchedRemoveStatusService, make SuspendAccountService use it
* Improve method names
* Add test
* Add more tests
* Use PuSH payloads of 100 to have a clear mapping of
1000 input statuses -> 10 PuSH payloads
It was nice while it lasted
* Add form for account deletion
* If avatar or header are gone from source, remove them
* Add option to have SuspendAccountService remove user record, add tests
* Exclude suspended accounts from search
* Fix#2619 - When redis feed is empty, fall back to database
* Use redis value to return feed from database only while RegenerationWorker
hasn't finished running
* Fix specs
* Replace usage of reject!
TagManager.local_url? was sometimes called with an URI with a nil host,
leading to a crash in TagManager.local_url?. This fixes moves the
already-existing uri.host.blank? check in front to avoid this case.
Steps to reproduce the original issue:
1. Have two remote accounts, A that you don't follow, and B that you follow.
2. Have A post a toot and reply to it.
3. Boost A's reply from remote account B.
This used to cause the local instance to get A's reply but fail to link it to
the original post.
* Try fixing ThreadResolveWorker calls
From my understanding of ActiveRecord, a transaction is commited as soon as
the exit of the outmost ActiveRecord.transaction block. However, inner
transaction blocks will exit without the transaction being commited.
In this case, ThreadResolveWorker were fired *within* a transaction block,
so moving the call out of it should do the trick. However, this is somewhat
fragile, as this whole codepath could be called within yet another transaction.
* Set status thread within the transaction block if it is immediately available from database
* Remove trailing whitespace in i18n mailers
* Use query methods instead of #present? on AR attributes
* Delegate Status#account_domain method
* Delegate Mention #account_username and #account_acct methods
* Fix nil input not handled well in AuthorExtractor concern
* Fix hard error in ProcessFeedService when replied-to status has been deleted
* Fix nil errors in ProcessInteractionService when favourited status
cannot be found
* Add buttons to block and unblock domain
* Relationship API now returns "domain_blocking" status for accounts,
rename "block entire domain" to "hide entire domain", fix unblocking domain,
do not block notifications from domain-blocked-but-followed people, do
not send Salmons to domain blocked users
* Add test
* Personal domain blocks shouldn't affect Salmon after all, since in this
direction of communication the control is very thin when it comes to
public stuff. Best stay consistent and not affect federation in this way
* Ignore followers and follow request from domain blocked folks,
ensure account domain blocks are not created for empty domain,
and avoid duplicates in validation
* Purge followers when blocking domain (without soft-blocks, since they
are useless here)
* Add tests, fix local timeline being empty when having any domain blocks
* Add <ostatus:conversation /> tag to Atom input/output
Only uses ref attribute (not href) because href would be
the alternate link that's always included also.
Creates new conversation for every non-reply status. Carries
over conversation for every reply. Keeps remote URIs verbatim,
generates local URIs on the fly like the rest of them.
* Conversation muting - prevents notifications that reference a conversation
(including replies, favourites, reblogs) from being created. API endpoints
/api/v1/statuses/:id/mute and /api/v1/statuses/:id/unmute
Currently no way to tell when a status/conversation is muted, so the web UI
only has a "disable notifications" button, doesn't work as a toggle
* Display "Dismiss notifications" on all statuses in notifications column, not just own
* Add "muted" as a boolean attribute on statuses JSON
For now always false on contained reblogs, since it's only relevant for
statuses returned from the notifications endpoint, which are not nested
Remove "Disable notifications" from detailed status view, since it's
only relevant in the notifications column
* Up max class length
* Remove pending test for conversation mute
* Add tests, clean up
* Rename to "mute conversation" and "unmute conversation"
* Raise validation error when trying to mute/unmute status without conversation
* Adding account domain blocks that filter notifications and public timelines
* Add tests for domain blocks in notifications, public timelines
Filter reblogs of blocked domains from home
* Add API for listing and creating account domain blocks
* API for creating/deleting domain blocks, tests for Status#ancestors
and Status#descendants, filter domain blocks from them
* Filter domains in streaming API
* Update account_domain_block_spec.rb
* Add <ostatus:conversation /> tag to Atom input/output
Only uses ref attribute (not href) because href would be
the alternate link that's always included also.
Creates new conversation for every non-reply status. Carries

Cleaner Ruby syntax, may handle immutable strings better
* Fix#2473 - Use sidekiq scheduler to refresh PuSH subscriptions instead of cron
Fix an issue where / in domain would raise exception in TagManager#normalize_domain
PuSH subscriptions refresh done in a round-robin way to avoid hammering a single
server's hub in sequence. Correct handling of failures/retries through Sidekiq (see
also #2613). Optimize Account#with_followers scope. Also, since subscriptions
are now delegated to Sidekiq jobs, an uncaught exception will not stop the entire
refreshing operation halfway through
Fix#2702 - Correct user agent header on outgoing http requests
* Add test for SubscribeService
* Extract #expiring_accounts into method
* Make mastodon:push:refresh no-op
* Queues are now defined in sidekiq.yml
* Queues are now in sidekiq.yml
* Likely fix#2458, fix#2031 - handle out-of-order deletes for statuses
If a delete arrives before the original status, cache that information
for 6h, and if the original status arrives in that window, ignore it
* Add test case
Fix#2196 - Respond with 201 when Salmon accepted, 400 when unverified
Fix#2629 - Correctly handle confirm_domain? for local accounts
Unify rules for extracting author acct from XML, prefer <email>, fall back
to <name> + <uri> (see also #2017, #2172)
Follow-up to #2599. When a domain block with `reject_media` is
added or `rake mastodon:media:remove_remote` is invoked, mastodon
deletes the locally cached attachments and avatars but does not
reflect that change in the database, causing the `file` fields to
still have values. This change persists the deletion in the
database and sets the attachment type to unknown.
This also introduces a one-off rake task that sets all attachments
without a local file to the "unknown" type. The upgrade notes for
the next release should contain a post-upgrade step with
`rake mastodon:media:set_unknown`.
* Instead of parsing shared status contents verbatim, make roundtrip
to purported original URL. Confirm that the "original" URL is from the
same domain as the author it claims to be from.
* Fix obvious typo, add comment
* Use URI look-up first
* Add test, update Goldfinger dependency to make less useless HTTP requests per Webfinger lookup
* OEmbed support for PreviewCard
* Improve ProviderDiscovery code failure treatment
* Do not crawl links if there is a content warning, since those
don't display a link card anyway
* Reset db schema
* Fresh migrate
* Fix rubocop style issues
Fix#1681 - return existing access token when applicable instead of creating new
* Fix test
* Extract http client to helper
* Improve oembed controller

This commit reduce following query:
```
MediaAttachment Load (0.9ms) SELECT "media_attachments".* FROM "media_attachments" WHERE "media_attachments"."status
_id" IS NULL AND 1=0 ORDER BY id asc
```
* fixed for more simple changes.
* Add language detection via WhatLanguage and (de)serialization of it through Atom
* Fix default language in ProcessFeedService
* Re-add newline before 'react-rails' Gem to fix groupings
Fixes Code Climate issue
The <link rel="mentioned" /> tag refers to accounts by href. So we were
matching the DB by the url attribute, and falling back to HTTP look-up.
However, GS and Mastodon use profile URLs as URIs, too, and the match
for that was missing. This could potentially alleviate some extra network
requests
Create MediaAttachment but without actual file download when domain is blocked with reject_media set to true
Clean up old media files when creating a new domain block with reject_media set to true
Return remote_url in media attachments API if local file is not present
Undo domain block action in admin UI
Ability to enable reject_media from admin UI
* Begin coverage for account search service
* Coverage for hashtag query
* Coverage for calling local vs remote find based on domain presence
* Spec to check that exact matches are not duped
* Coverage of resolve option
* Coverage for account being provided
* Start to refactor account search service
* Isolate query username and domain methods
* Isolate exact_match method
* Extract methods for local and remote results
* Simplify local vs remote and account isoliation
* Extract methods for local and remote results
* Simplify de-dupe of exact match
* Simplify logic to check for non exact remotes
* Cache some methods
* Remove nil from exact_match from results array
* Return exact matches first
* Use find_remote even with no domain
Account.find_local is just an alias for Account.find_remote(user, nil) - so we
can not bother with the conditional here, and call find_remote directly.
* Refresh local info for remote accounts when webfinger returns new values
It only refreshes account info if one of the URLs or the public-key changes,
in which cases it refreshes the full info, re-downloading the feeds from that
user.
Some special handling should probably be done when the public key changes,
but I have been unable to find any use for it in Mastodon yet.
* Re-fetch remote users we aren't subscribed to.
This might induce performance issues, we might want to only do that for users
we explicitly attempted to subscribe but failed to.
* Refactor changes
* Do not refresh existing remote account details more than once a day
* Avoid re-fetching webfinger info in tests unless otherwise specified
* Allow running mastodon on a different domain as the one used for identifying users
* Alter documentation of WEB_DOMAIN to make clear it shouldn't be used unless the admin knows what they are doing
* Compare to web_domain instead of local_domain when dealing with feeds/API
* Correctly identify mentions to local accounts
Mentions URLs point to the person's web profile, i.e., the user page served on WEB_DOMAIN.
The goal of this change is to enhance Mastodon's handling of remote domains
for which the APIs reside on a different host (see issue #1032).
Indeed, when a remote user unknown to Mastodon is mentionned, only its profile
URL (e.g. https://social.example.org/users/User) is known, and Mastodon has to
build a @username@domain handle for it. To do so, Mastodon fetches the user's
atom feed (e.g., https://social.example.org/users/User.atom) and uses its
content to get the username part of the handle, and the URL's host part to
build the domain (e.g., @User@social.example.org). This handle is then used
for a Webfinger request.
In the case where example.org serves the Webfinger info for @User@example.org
and all feeds and APIs are hosted at social.example.org, Mastodon will still
build @User@social.example.org and fail at resolving the account's details
through Webfinger.
This patch changes this behaviour by using the author's email address from
the atom feed to build the handle. In Mastodon-generated atom feeds, the
email address is always the handle it expects for federation.
* Fix#1141, fix#1126 - Work through UpdateRemoteProfileService for both <feed> and <entry> top-level tags
* Improve code quality, remove line unrelated to fix
* Rewrite Atom generation from stream entries to use Ox instead of Nokogiri::Builder
StreamEntry is now limited to only statuses, which allows some optimization. Removed
extra queries on AccountsController#show. AtomSerializer instead of AtomBuilderHelper
used in AccountsController#show, StreamEntriesController#show, StreamEntryRenderer
and PubSubHubbub::DistributionWorker
PubSubHubbub::DistributionWorker moves n+1 DomainBlock query to PubSubHubbub::DeliveryWorker
instead.
All Salmon slaps that aren't based on StreamEntry still use AtomBuilderHelper and Nokogiri
* All Salmon slaps now use Ox instead of Nokogiri. No touch from status on account
FanOutOnWriteService. The only recipient-specific part on them
is reblogged/favourited. But since only newly created statuses
appear on them, it is safe to assume that both attributes would
be false
fix ProcessFeedService pushing status into distribution if called a second time
while the first is still running (i.e. when a PuSH comes after a Salmon slap),
fix not running escape on spoiler text before emojify
Federate spoiler_text using warning attribute on <content /> instead of a <category term="spoiler" />
Clean up schema file from accidental development migrations
application website validation, don't link to app website if website isn't set,
also comment out animated boost icon from #464 until it's consistent with non-animated version
Filters out hidden stream entries from Atom feed
Blocks now generate hidden stream entries, can be used to federate blocks
Private statuses cannot be reblogged (generates generic 422 error for now)
POST /api/v1/statuses now takes visibility=(public|unlisted|private) param instead of unlisted boolean
Statuses JSON now contains visibility=(public|unlisted|private) field
Fetching atom extracted from FetchRemoteAccountService and FetchRemoteStatusService
into FetchAtomService. Mentions of the constant "http://activityschema.org/collection/public"
skipped as it's not a real URL/user.
This is a big one, so let me enumerate:
Accounts as well as stream entry pages now contain Link headers that
reference the Atom feed and Webfinger URL for the former and Atom entry
for the latter. So you only need to HEAD those resources to get that
information, no need to download and parse HTML <link>s.
ProcessFeedService will now queue ThreadResolveWorker for each remote
status that it cannot find otherwise. Furthermore, entries are now
processed in reverse order (from bottom to top) in case a newer entry
references a chronologically previous one.
ThreadResolveWorker uses FetchRemoteStatusService to obtain a status
and attach the child status it was queued for to it.
FetchRemoteStatusService looks up the URL, first with a HEAD, tests
if it's an Atom feed, in which case it processes it directly. Next
for Link headers to the Atom feed, in which case that is fetched
and processed. Lastly if it's HTML, it is checked for <link>s to the Atom
feed, and if such is found, that is fetched and processed. The account for
the status is derived from author/name attribute in the XML and the hostname
in the URL (domain). FollowRemoteAccountService and ProcessFeedService
are used.
This means that potentially threads are resolved recursively until a dead-end
is encountered, however it is performed asynchronously over background jobs,
so it should be ok.
