Conflicts:
app/javascript/mastodon/initial_state.js

Upstream added a new field to initial_state.
Not too sure about what happened with db/schema.rb though…
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.
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.
This has a couple of advantages over the regex approach:
- Keywords are individually addressable, which makes it easier to gather
statistics (#363)
- Keywords can be individually applied to different feeds, e.g. skipping
mentions (#454)
It *does* end up creating many more Regexp objects. I'm not yet sure if
the difference is significant.
Conflicts:

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
under the Misc option). They were resolved via accept-ours.

> Good lord what is happening in there
Previously the contents of the Web Push API payloads closely resembled the structure of JavaScript's [Notification](https://developer.mozilla.org/en-US/docs/Web/API/Notification). But now that the API is open to non-browser apps, and given that there is no required coupling between contents of the payload and a Notification object, here is how I changed the payload:
```json
{
"access_token": "...",
"preferred_locale": "en",
"notification_id": "12345",
"notification_type": "follow",
"title": "So and so followed you",
"body": "This is my bio",
"icon": "https://example.com/avatar.png"
}
```
The title, body and icon attributes are included as a fallback so you can construct a minimal notification if you cannot perform a network request to the API to get more data.
* 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
- POST /api/v1/push/subscription
- PUT /api/v1/push/subscription
- DELETE /api/v1/push/subscription
- New OAuth scope: "push" (required for the above methods)
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 9c1e1005f4.
* 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
* Add entity cache
Use a caching layer for mentions and custom emojis that are
dynamically extracted from text.
Reduce duplicate text extractions
* Fix code style issue
The goal here isn't to prevent these hashtags from existing, but just to strongly curtail their usage; The hashtags may still exist in the database via federated status, or from being created prior to this feature.

Fix#121
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.
* Further improvements to Reports UI
- Clean up notes display
- Clean up add new note form
- Simplify controller
- Allow reopening a report with a note
- Show created at date for reports

* Improve report history builder
Thanks @gargron for the improvements
* Admin: Show unconfirmed email address on account page
* Admin: Allow staff to change user email addresses
* ActionLog: On change_email, log current email address and new unconfirmed email address
- Explicitly specify video codec.
When ffmpeg isn't compiled with libx264 but openh264, mpeg4 is selected as video codec.
- Swap avarage bitrate and max bitrate.
ancestor_statuses and descendant_statuses used to include the root status
itself, but the behavior is confusing because the root status is not
an ancestor nor descendant.
* Implement Assignment of Reports (#6967)
* Change translation of admin.report.comment.label to "Report Comment" for clarity
As we'll soon add the ability for reports to have comments on them, this clarification makes sense.
* Implement notes for Reports
This enables moderators to leave comments about a report whilst they work on it
* Fix display of report moderation notes
* Allow reports to be reopened / marked as unresolved
* Redirect to reports listing upon resolution of report
* Implement "resolve with note" functionality
* Add inverse relationship for report notes

Comparison was downcasing only one side, therefore if previously
existing account had a non-lowercase spelling, it would be ignored
when checking for duplicates.
New rake task `mastodon:maintenance:find_duplicate_usernames` will
help find constraint violations that might have occured from the
presence of this bug.
Bump version to 2.3.3
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.
Usernames with dots in them do not work with routes, because the dot usually separates the desired page format (e.g. json). I don't want to mess with changing route constraints for this patch release.
* Permit dots in usernames with conditions
- Dot cannot be the start or end of username
- a.lice and al.ice are considered the same during sign-up
* Fix regex mixin flags
* update to new version of devise_pam_authenticatable2
* fix behaviour if suffix is nil, fix environment loading, fix user email creation
* code cleanup/fix linter warning
This will prevent, for example, `rake mastodon:redownload_avatars` from crashing when an instance is no longer responding to connection attempts, instead silently continuing as expected.
* Rescue when there's no extension in the remotable
Sometimes the remotable is pointing to a directory with no file
extension. Maybe it should not be expecting to identify based on
extensions to begin with, but since it's the case, it should be ready
for it.
* Fix codeclimate issue
* Check if filename is nil instead of rescueing exception
Suggestion made in the PR
* Avoid concatenation issue if filename is nil
If filename is nil, extname was undefined
* Invert condition
Address PR comments
* Fix prev/next links on public profile page
* Don't make pagination urls if no available statuses
* Fix empty check method
* Put left chevron before prev page link
* Add scope for pagination "starting at" a given id
* Status pagination try 2:
s/prev/older and s/next/newer
"older" on left, "newer" on right
Use new scope for "newer" link
Extract magic 20 page size to constant
Remove max_id from feed pagination as it's not respected
* Reinstate max_id for accounts atom stream
* normalize
* Ensure the app does not even start if OTP_SECRET is not set
* Remove PAPERCLIP_SECRET (it's not used by anything, actually)
Imports are for internal consumption and the url option isn't even
used correctly, so we can remove the hash stuff from them
* Add focus param to media API, center thumbnails on focus point
* Add UI for setting a focal point
* Improve focal point icon on upload item
* Use focal point in upload preview
* Add focalPoint property to ActivityPub
* Don't show focal point button for non-image attachments
* 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
* Fix avatar and header issues by using custom geometry detector
Revert a part of #6508. The file passed to dynamic styles method
was not actually a file, but an instance of Paperclip::Attachment,
which broke all styles by always returning {} from the method.
One problem with GIF avatars was that Paperclip::GeometryDetector
reported wrong dimensions for them, e.g. 120x120 GIF avatar would
for some reason be detected as 120x53. By writing our own geometry
parser, we can use FastImage, which also happens to be faster than
ImageMagick, to detect image dimensions, which are also correct.
Unfortunately, this PR does not implement skipping a `convert`
entirely if the dimensions are already correct, as I found no easy
way to write that behaviour into Paperclip without rewriting the
Paperclip::Thumbnail class.
* Only invoke convert if dimension or format needs to be changed
Also don't apply "-quality 80" option which is probably the reason
for slight color differences between original and remote image
(because it would apply it twice, once on original instance, and
again on the receiving instance)
* 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
Fix#5880Fix#4293Fix#1152
* Add commented out docker-compose configuration for ES container
* Optimize index import, filter search results
* Add basic normalization to the index
* Add better stemming and normalization to the index
* Skip webfinger request if search query includes both @ and a space
* Fix code style
* Visually separate search result sections
* Fix code style issues
* Add option to show only local toots in timeline preview
Right know, toots from all the known fediverse are shown in the main
page of an instance. That however doesn't reflect the instance itself.
With this option the admin may choose to display only local toots so
that users checking the instance get a better idea of internal
conversations.
* Fix issues pointed by codeclimate and eslint
* Add default message for community timeline
* Update pl.yml
UserTrackingConcern is circumvented by SessionsController#create
because it calls warden, which calls the User#update_tracked_fields!
method directly. Move returning user logic to that method.
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.
* 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.

* 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.

* 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 consumable invites
* Add UI for generating invite codes
* Add tests
* Display max uses and expiration in invites table, delete invite
* Remove unused column and redundant validator
- Default follows not used, probably bad idea
- InviteCodeValidator is redundant because RegistrationsController
checks invite code validity
* Add admin setting to disable invites
* Add admin UI for invites, configurable role for invite creation
- Admin UI that lists everyone's invites, always available
- Admin setting min_invite_role to control who can invite people
- Non-admin invite UI only visible if users are allowed to
* Do not remove invites from database, expire them instantly
* Serialize moved accounts into REST and ActivityPub APIs
* Parse federated moved accounts from ActivityPub
* Add note about moved accounts to public profiles
* Add moved account message to web UI

* 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
=~ 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.
We already know about one regex limitation, which is that they cannot
segment words in e.g. Japanese, Chinese, or Thai. It may also end up
that regex matching is too slow compared to other methods.
However, the regex is an implementation detail. We still want the
ability to switch between "occurs anywhere" and "match whole word", and
caching the matcher result is likely to still be important (since the
matcher itself won't change nearly as often as status ingress rate).
Therefore, we ought to be able to change the cache keys to reflect a
change of data structure.
(Old cache keys expire within minutes, so they shouldn't be too big of
an issue. Old cache keys could also be explicitly removed by an
instance administrator.)
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.
* Add a hide_notifications column to mutes
* Add muting_notifications? and a notifications argument to mute!
* block notifications in notify_service from hard muted accounts
* Add specs for how mute! interacts with muting_notifications?

* Less gross passing of notifications flag
* Break out a separate mute modal with a hide-notifications checkbox.
* Convert profile header mute to use mute modal
* Satisfy eslint.
* specs for MuteService notifications params
* add trailing newlines to files for Pork :)
* Put the label for the hide notifications checkbox in a label element.
* Add a /api/v1/mutes/details route that just returns the array of mutes.
* Define a serializer for /api/v1/mutes/details
* Add more specs for the /api/v1/mutes/details endpoint
* Expose whether a mute hides notifications in the api/v1/relationships endpoint
* Show whether muted users' notifications are muted in account lists
* Allow modifying the hide_notifications of a mute with the /api/v1/accounts/:id/mute endpoint
* make the hide/unhide notifications buttons work
* satisfy eslint
* In probably dead code, replace a dispatch of muteAccount that was skipping the modal with launching the mute modal.
* fix a missing import
* add an explanatory comment to AccountInteractions
* Refactor handling of default params for muting to make code cleaner
* minor code style fixes oops
* Fixed a typo that was breaking the account mute API endpoint
* Apply white-space: nowrap to account relationships icons
* Fix code style issues
* Remove superfluous blank line
* Rename /api/v1/mutes/details -> /api/v2/mutes
* Don't serialize "account" in MuteSerializer
Doing so is somewhat unnecessary since it's always the current user's account.
* Fix wrong variable name in api/v2/mutes
* Use Toggle in place of checkbox in the mute modal.
* Make the Toggle in the mute modal look better
* Code style changes in specs and removed an extra space
* Code review suggestions from akihikodaki
Also fixed a syntax error in tests for AccountInteractions.
* Make AddHideNotificationsToMute Concurrent
It's not clear how much this will benefit instances in practice, as the
number of mutes tends to be pretty small, but this should prevent any
blocking migrations nonetheless.
* Fix up migration things
* Remove /api/v2/mutes
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.
All the migrations have been updated to use BIGINTs for ID fields in the DB, but ActiveRecord needs to be told to treat those values as BIGINT as well. This PR does that.
* Add moderator role and add pundit policies for admin actions
* Add rake task for turning user into mod and revoking it again
* Fix handling of unauthorized exception
* Deliver new report e-mails to staff, not just admins
* Add promote/demote to admin UI, hide some actions conditionally
* Fix unused i18n
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.
* 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.
* Show the local couterpart of emoji when it exists in admin/custom_emojis
* Fix indentation
* Fix error
* Add class table-action-link to Overwrite link
* Make it enable to overwrite emojis
* Make Code Climate happy
Also make the keyword-building methods private: they always probably
should have been private, but now I have encoded enough fun and games
into them that it now seems wrong for them to *not* be private.
It is possible to cache a Regexp object, but I'm not sure what happens
if e.g. that object remains in cache across two different Ruby versions.
Caching a string seems to raise fewer questions.
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.

The intent of the previous concatenation was to minimize object
allocations, which can end up being a slow killer. However, it turns
out that under MRI 2.4.x, the shove-strings-in-an-array-and-join method
is not only arguably more common but (in this particular case) actually
allocates *fewer* objects than the string concatenation.
Or, at least, that's what I gather by running this:

a = Account.first

GC.start
s1 = GC.stat
re = String.new.tap do |str|
scoped = KeywordMute.where(account: a)
keywords = scoped.select(:id, :keyword)
count = scoped.count
keywords.find_each.with_index do |kw, index|
str << Regexp.escape(kw.keyword.strip)

end
end

vs this:

Using rails r, here is a comparison of the total_allocated_objects and
malloc_increase_bytes GC stat data:
total_allocated_objects malloc_increase_bytes
string concat 3200241 -> 3201428 (+1187) 1176 -> 45216 (44040)
array join 3200380 -> 3201299 (+919) 1176 -> 36448 (35272)
It would also have been valid to get rid of the attr_reader, but I like
being able to reach inside KeywordMute::Matcher without resorting to
instance_variable_get tomfoolery.
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.
* Add option to reduce motion
* Use HOC to wrap all Motion calls
* fix case-sensitive issue
* Avoid updating too frequently
* Get rid of unnecessary change to _simple_status.html.haml
The main change of this PR is removing `order by visibility` hack.
This was introduced to force using of `index_statuses_on_account_id` instead of PK index, but it seems no longer needed probably due to `index_statuses_on_account_id_id`. Removing this avoids reading all rows, so really improves first fetching of the user who has lot of statuses.
I have also changed JOIN to IN + subquery, which slightly faster in most cases.
- For some reason, :if option on before_action did not work. It got
executed every time, returned false, and the action run anyway,
which led to the current_sign_in_at and sign_in_count being
updated on every request
- Return "do not filter" early in FeedManager#filter_from_home? if
the status is authored by receiver. Usually this method is not
called for own statuses at all, but it is called when Feed#get
uses the database
- Return early if #reload_stale_associations! has nothing to load
to save a database query with WHERE 1=0
* Retoot count increases without reason
-The store_uri method for Statuses was being called on after_create and causing reblogs to be incremented twice.
-This calls it when the transaction is finished by using after_create_commit.
-Fixes #4916.
* Added test case for after_create_commit callback for checking reblog count.
* Rewrote test to keep original, but added one for only the after_create_commit callback.
* Add foreign key constraint to column `account` in `account_moderation_notes`
* Change account_id and target_account_id to non-nullable in account_moderation_notes
* Add dependent: :destroy to account and target_account in account_moderation_notes
- Rename Mastodon::TimestampIds into Mastodon::Snowflake for clarity
- Skip for statuses coming from inbox, aka delivered in real-time
- Skip for statuses that claim to be from the future
* 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.

* 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.
* Make IdsToBigints (mostly!) non-blocking
This pulls in GitLab's MigrationHelpers, which include code to make
column changes in ways that Postgres can do without locking. In general,
this involves creating a new column, adding an index and any foreign
keys as appropriate, adding a trigger to keep it populated alongside
the old column, and then progressively copying data over to the new
column, before removing the old column and replacing it with the new
one.
A few changes to GitLab's MigrationHelpers were necessary:
* Some changes were made to remove dependencies on other GitLab code.
* We explicitly wait for index creation before forging ahead on column
replacements.
* We use different temporary column names, to avoid running into index
name length limits.
* We rename the generated indices back to what they "should" be after
replacing columns.
* We rename the generated foreign keys to use the new column names when
we had to create them. (This allows the migration to be rolled back
without incident.)
# Big Scary Warning
There are two things here that may trip up large instances:
1. The change for tables' "id" columns is not concurrent. In
particular, the stream_entries table may be big, and does not
concurrently migrate its id column. (On the other hand, x_id type
columns are all concurrent.)
2. This migration will take a long time to run, *but it should not
lock tables during that time* (with the exception of the "id"
columns as described above). That means this should probably be run
in `screen` or some other session that can be run for a long time.
Notably, the migration will take *longer* than it would without
these changes, but the website will still be responsive during that
time.
These changes were tested on a relatively large statuses table (256k
entries), and the service remained responsive during the migration.
Migrations both forward and backward were tested.
* Rubocop fixes
* MigrationHelpers: Support ID columns in some cases
This doesn't work in cases where the ID column is referred to as a
foreign key by another table.
* MigrationHelpers: support foreign keys for ID cols
Note that this does not yet support foreign keys on non-primary-key
columns, but Mastodon also doesn't yet have any that we've needed to
migrate.
This means we can perform fully "concurrent" migrations to change ID
column types, and the IdsToBigints migration can happen with effectively
no downtime. (A few operations require a transaction, such as renaming
columns or deleting them, but these transactions should not block for
noticeable amounts of time.)
The algorithm for generating foreign key names has changed with this,
and therefore all of those changed in schema.rb.
* Provide status, allow for interruptions
The MigrationHelpers now allow restarting the rename of a column if it
was interrupted, by removing the old "new column" and re-starting the
process.
Along with this, they now provide status updates on the changes which
are happening, as well as indications about when the changes can be
safely interrupted (when there are at least 10 seconds estimated to be
left before copying data is complete).
The IdsToBigints migration now also sorts the columns it migrates by
size, starting with the largest tables. This should provide
administrators a worst-case scenario estimate for the length of
migrations: each successive change will get faster, giving admins a
chance to abort early on if they need to run the migration later. The
idea is that this does not force them to try to time interruptions
between smaller migrations.
* Fix column sorting in IdsToBigints
Not a significant change, but it impacts the order of columns in the
database and db/schema.rb.
* Actually pause before IdsToBigints
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
* Fix#117 - Add ability to specify alternative text for media attachments
- POST /api/v1/media accepts `description` straight away
- PUT /api/v1/media/:id to update `description` (only for unattached ones)
- Serialized as `name` of Document object in ActivityPub
- Uploads form adjusted for better performance and description input
* Add tests
* Change undo button blend mode to difference
