Compression with Pillow can take long, especially with large
clipboard PNG images.
Doing this in a separate process prevents the async event loop from
getting blocked, and allows multiple compression operations to run in
parallel.
It's possible to get a MatrixForbidden error when trying to retrieve a
offline room member's presence, if that member actually left the room
but the server hasn't yet sent the update.
This required us to set the media downloaded local path on events
entirely from python instead of simply lazy-fetching them when needed
from QML, due to pyotherside's async nature and files that must be open
in a certain order.
A healthy client must not only have a sync task running, but also have
finished its initial sync and have been succesful in its last sync
attempt.
The previous weak requirement caused this issue:
Have two clients, one on a failing server, and try to fetch a media,
thumbnail or profile: since these functions don't need auth, any
healthy client is picked to do the request, but the previous
requirement made it possible to pick the failing client.
Replace the poorly implemented 2-in-1 "copy address" media event
menu option with:
- Copy <mediaType> address: visible for non-encrypted media, always
copies the http URL
- Copy local path: always visible for already downloaded media, even if
they were downloaded before mirage was started
Fix bug introduced in 11fb32:
When loading an encrypted thumbnail, QML lacks the decryption dict for
half a second at first.
When calling python like this, python calls the wrong matrix API
for fetching the encrypted thumbnail, and the added retry code
would be forever stuck.
The retry code has been moved to QML, and now works for all HImage.
The attributes by mistake used nio.AsyncClient.user instead of the
proper user_id. If the user logged in with a partial username instead of
typing their full ID, the can_ attributes (e.g. can_kick) would always
be False.
