Implemented full support for ALL.Net China (maybe not?), including the implementation of auth and chimedb
PRiSM version support refers to the code in https://github.com/MewoLab/AquaDX
Instead of retrieving the entire list of items/characters/scores/etc. at once (and even store them in memory), use SQL's `LIMIT ... OFFSET ...` pagination so we only take what we need. Currently only CHUNITHM uses this, but this will also affect maimai DX and O.N.G.E.K.I. once the PR is ready. Also snuck in a fix for CHUNITHM/maimai DX's `GetUserRivalMusicApi` to respect the `userRivalMusicLevelList` sent by the client. ### How this works Say we have a `GetUserCharacterApi` request: ```json { "userId": 10000, "maxCount": 700, "nextIndex": 0 } ``` Instead of getting the entire character list from the database (which can be very large if the user force unlocked everything), add limit/offset to the query: ```python select(character) .where(character.c.user == user_id) .order_by(character.c.id.asc()) .limit(max_count + 1) .offset(next_index) ``` The query takes `maxCount + 1` items from the database to determine if there is more items than can be returned: ```python rows = ... if len(rows) > max_count: # return only max_count rows next_index += max_count else: # return everything left next_index = -1 ``` This has the benefit of not needing to load everything into memory (and also having to store server state, as seen in the [`SCORE_BUFFER` list](2274b42358/titles/chuni/base.py (L13)).)
