From 8843f18f5f12cefbad340c86710a54d71bf128fe Mon Sep 17 00:00:00 2001 From: Daniel Sockwell Date: Wed, 18 Mar 2020 20:37:10 -0400 Subject: [PATCH] Fix valid language (#93) * Fix panic on delete events Previously, the code attempted to check the toot's language regardless of event types. That caused a panic for `delete` events, which lack a language. * WIP implementation of Message refactor * Major refactor * Refactor scope managment to use enum * Use Timeline type instead of String * Clean up Receiver's use of Timeline * Make debug output more readable * Block statuses from blocking users This commit fixes an issue where a status from A would be displayed on B's public timelines even when A had B blocked (i.e., it would treat B as though they were muted rather than blocked for the purpose of public timelines). * Fix bug with incorrect parsing of incomming timeline * Disable outdated tests * Bump version --- Cargo.lock | 69 +- Cargo.toml | 3 +- src/err.rs | 8 + src/main.rs | 51 +- src/parse_client_request/sse.rs | 786 +++++++++--------- .../user/mock_postgres.rs | 9 +-
