All conflicts are due to upstream refactoring feed management and us having
local-only toots on top of that. Rewrote local-only toots management for
upstream's changes.
* 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
Conflicts:
- `app/controllers/activitypub/collections_controller.rb`:
Conflict caused because we have additional code to make sure pinned
local-only toots don't get rendered on the ActivityPub endpoints.
Ported upstream changes.
* 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
Conflicts:
- `app/controllers/accounts_controller.rb`:
Upstream change too close to a glitch-soc change related to
instance-local toots. Merged upstream changes.
- `app/services/fan_out_on_write_service.rb`:
Minor conflict due to glitch-soc's handling of Direct Messages,
merged upstream changes.
- `yarn.lock`:
Not really a conflict, caused by glitch-soc-only dependencies
being textually too close to updated upstream dependencies.
Merged upstream changes.
* Change content-type to be always computed from file data
Restore previous behavior, detecting the content-type isn't very
expensive, and some instances may serve files as application/octet-stream
regardless of their true type, making fetching media from them fail, while
it used to work pre-3.2.0.
* Add test
Conflicts:
- `app/javascript/mastodon/actions/compose.js`:
Not a “real” conflict, but change too close to a change we made to
fix the vanilla WebUI locally pushing authored local-only toots in the
public TL view.
* 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.
Conflicts:
- `app/controllers/activitypub/collections_controller.rb`:
Conflict due to glitch-soc having to take care of local-only
pinned toots in that controller.
Took upstream's changes and restored the local-only special
handling.
- `app/controllers/auth/sessions_controller.rb`:
Minor conflicts due to the theming system, applied upstream
changes, adapted the following two files for glitch-soc's
theming system:
- `app/controllers/concerns/sign_in_token_authentication_concern.rb`
- `app/controllers/concerns/two_factor_authentication_concern.rb`

Not a real conflict, just a glitch-soc-only dependency too close to a
dependency that got updated upstream. Updated as well.
- `app/models/status.rb`:
Not a real conflict, just a change too close to glitch-soc-changed code
for optionally showing boosts in public timelines.
Applied upstream changes.
- `app/views/layouts/application.html.haml`:
Upstream a new, static CSS file, conflict due to glitch-soc's theming
system, include the file regardless of the theme.
- `config/initializers/content_security_policy.rb`:
Upstream dropped 'unsafe-inline' from the 'style-src' directive, but
both files are very different. Removed 'unsafe-inline' as well.
* 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

Twitter doesn't serialize title either, and tihs allows us to move the
title formatting code to the RSS serializers.

with slightly different code. Discarded upstream's changes.
- `package.json`:
No real conflict, glitch-soc-only dependency (favico.js) too close to
an upstream one
* 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
Conflicts:
- `config/locales/en.yml`
No real conflict, upstream added a translatable string “too close” to
one specific to glitch-soc

Fixes made upstream, while changed in glitch-soc to keep bookmarked statuses
- `package.json`
No real conflict, additional dependency in glitch-soc

* Ensure blocked user unfollows blocker if Block/Undo Block are processed out of order
* Add specs for Block causing unfollow and for out-of-order Block + Undo
* 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

* 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

Ported glitch changes to webpack 4.x
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
Completely remove glitch-soc's Keyword Mutes, migrate

Conflicts:
README.md
app/controllers/statuses_controller.rb

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 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.
* 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
Conflicts:
app/serializers/initial_state_serializer.rb
The glitch flavour isn't yet pulling custom emoji data on its own (see
https://github.com/tootsuite/mastodon/pull/7047). Once that gets into
the glitch flavour, we can eliminate the custom_emojis load.
* 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
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
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.
* Fix actors accepting invalid URI schemes or different host between URI and URL
* Fix statuses accepting invalid URI scheme or different host to actor
* Adjust tests to new requirements
* Improve readability of mismatching_origin?/invalid_origin? methods
* 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
* 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.
See also <https://github.com/glitch-soc/mastodon/pull/212>.
* Rubocop fixes
* Code review changes
* Test fixes
This patchset closes#648 and resolves#3271.
* Rubocop fix
* 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.
* Add structure for lists
* Add list timeline streaming API
* Add list APIs, bind list-account relation to follow relation
* Add API for adding/removing accounts from lists
* Add pagination to lists API
* Add pagination to list accounts API
* Adjust scopes for new APIs
- Creating and modifying lists merely requires "write" scope
- Fetching information about lists merely requires "read" scope
* Add test for wrong user context on list timeline
* Clean up tests
* 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
