The dragged item's position now only updates after the drag finishes. Local handling changes were required to ignore the bindable remove/add events that are fired as a result.
Upon investigating an user report in #6091 that indicated that viewing
replays using the Perfect mod would also display the Sudden Death mod
icon despite Perfect being the more restrictive of the two, it turned
out that the logic of importing legacy scores was missing that corner
case. A similar case of Double Time/Nightcore mutual exclusion was
handled, but PF/SD was missed.
Add analogous handling of PF/SD legacy mods for all four rulesets,
and additionally cover a tiny fraction of all cases with unit tests.
The most problematic cases (NC+HD and PF+SD) are covered in all four
basic rulesets.
This took around under a hour to implement, it has the same behavior and content from osu!stable.
A notification will show up when the user has either its master or track volume set to the minimum, clicking it will set it to the default values.
After the preparatory introduction of LineBufferedReader, it is now
possible to introduce registration of fallback decoders that won't drop
input supplied in the first line of the file.
A fallback decoder is used when the magic in the first line of the file
does not match any of the other known decoders. In such a case,
the fallback decoder is constructed and provided a LineBufferedReader
instance. The process of matching magic only peeks the first non-empty
line, so it is available for re-reading in Decode() using ReadLine().
There can be only one fallback decoder per type; a second attempt of
registering a fallback will result in an exception to avoid bugs.
To address the issue of parsing failing on badly or non-headered files,
set the legacy decoders for Beatmaps and Storyboards as the fallbacks.
Due to non-trivial logic, several new, passing unit tests with possible
edge cases also included.
