[performance] refactoring + add fave / follow / request / visibility caching (#1607) * refactor visibility checking, add caching for visibility * invalidate visibility cache items on account / status deletes * fix requester ID passed to visibility cache nil ptr * de-interface caches, fix home / public timeline caching + visibility * finish adding code comments for visibility filter * fix angry goconst linter warnings * actually finish adding filter visibility code comments for timeline functions * move home timeline status author check to after visibility * remove now-unused code * add more code comments * add TODO code comment, update printed cache start names * update printed cache names on stop * start adding separate follow(request) delete db functions, add specific visibility cache tests * add relationship type caching * fix getting local account follows / followed-bys, other small codebase improvements * simplify invalidation using cache hooks, add more GetAccountBy___() functions * fix boosting to return 404 if not boostable but no error (to not leak status ID) * remove dead code * improved placement of cache invalidation * update license headers * add example follow, follow-request config entries * add example visibility cache configuration to config file * use specific PutFollowRequest() instead of just Put() * add tests for all GetAccountBy() * add GetBlockBy() tests * update block to check primitive fields * update and finish adding Get{Account,Block,Follow,FollowRequest}By() tests * fix copy-pasted code * update envparsing test * whitespace * fix bun struct tag * add license header to gtscontext * fix old license header * improved error creation to not use fmt.Errorf() when not needed * fix various rebase conflicts, fix account test * remove commented-out code, fix-up mention caching * fix mention select bun statement * ensure mention target account populated, pass in context to customrenderer logging * remove more uncommented code, fix typeutil test * add statusfave database model caching * add status fave cache configuration * add status fave cache example config * woops, catch missed error. nice catch linter! * add back testrig panic on nil db * update example configuration to match defaults, slight tweak to cache configuration defaults * update envparsing test with new defaults * fetch followingget to use the follow target account * use accounnt.IsLocal() instead of empty domain check * use constants for the cache visibility type check * use bun.In() for notification type restriction in db query * include replies when fetching PublicTimeline() (to account for single-author threads in Visibility{}.StatusPublicTimelineable()) * use bun query building for nested select statements to ensure working with postgres * update public timeline future status checks to match visibility filter * same as previous, for home timeline * update public timeline tests to dynamically check for appropriate statuses * migrate accounts to allow unique constraint on public_key * provide minimal account with publicKey --------- Signed-off-by: kim <grufwub@gmail.com> Co-authored-by: tsmethurst <tobi.smethurst@protonmail.com>
