2018-03-26Validate HTTP response length while receiving (#6891)Akihiko Odaki
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.
2018-03-24Close http connection in perform method of Request class (#6889)Akihiko Odaki
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.
2018-03-20request: in the event of failure, try other IPs (#6761) (#6813)Rey Tucker
* 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

2018-02-24Do not push status to feed if its reblog is already inserted (#6488)Akihiko Odaki
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.

2017-11-28Allow hiding of reblogs from followed users (#5762)aschmitz
* 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.

2017-10-17Clean up reblog tracking keys, related improvements (#5428)aschmitz
* 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.
2017-10-16Keep references to all reblogs of a status on home feed (#5419)Eugen Rochko
* 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
2017-10-16Fix un-reblogged status being at wrong position in the home timeline (#5418)unarist
We've changed un-reblogging behavior when we implement Snowflake, to insert un-reblogged status at the position reblogging status existed. However, our API expects home timeline is ordered by status ids, and max_id/since_id filters by zset score. Due to this, un-reblogged status appears as a last item of result set, and timeline expansion may skips many statuses. So this reverts that change...reblogged status inserted at corresponding position to its id.
2017-10-14Use atomUri in Undo activity of Announce (#5376)unarist
This allows deletion of reblogs which delivered before with OStatus URI.

* Encode custom emojis as resolveable objects in ActivityPub * Improve code style
2017-10-04Non-Serial ("Snowflake") IDs (#4801)aschmitz
* 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_r139336735 https://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.
