MembersSyncError: The room is encrypted and the members aren't fully synced. about mirage HOT 21 CLOSED

Just tested on another existing account without importing a key file from Riot, and same result. Consistently getting this error about members not being synced.

from mirage.

I think the issue comes from here in nio, where I added some prints. Can you install this branch, restart mirage and report what appears in your terminal then when you try to send a message?

git clone https://github.com/mirukana/matrix-nio
cd matrix-nio
git checkout origin/mirage-issue-54
pip3 install --user -U '.[e2e]'

from mirage.

I've redacted much of the personal info in here since it had my token and a very large list of room members, but here is basically what I got:

Members synced: False

I updated the branch to add more logging, make sure to paste all the lines (you missed the "members synced 2" in the previous post).

from mirage.

ok, this is starting to happen in more encrypted rooms, and logging out and back in doesn't fix the issue which is really odd, and even though my other account doesn't show up in the encrypted roomlist, i can still send messages from that account into the room, but the icon and name are missing, until i re-open the room .

Can you do this then?

from mirage.

one thing i've noticed with this error, is that my other account is always what's missing from the sidebar, it's never another room member, it can't be a coincidence so many times ?

from mirage.

and if i send messages from the other account, and then close and re-open the room, sometimes the other account will show up, and then it lets me send messages .

How many joined members does this room contain, including yourself, with a fully loaded member list? 4?

from mirage.

4, yes .

from mirage.

I can confirm that it happens on Manjaro-arm (PineBook Pro) too. That's maybe the main thing which makes Mirage unusable for me. I still can read the messages from the encrypted rooms.

from mirage.

Can you still reproduce this after the dev branch commit d127ad9?
You might need to install a special branch of matrix-nio for the test, see #31 (comment)

from mirage.

It's much better, but it still happens for some encrypted rooms. It looks like it happens on some crowded ones, but that's just a speculation. I'm using the head on the dev branch.

from mirage.

I need more info on the room that fails, compare Mirage's member list with the one from a client that handles the room correctly (e.g. Element):

• Is there any member that shouldn't be here, e.g. members that already left or were kicked?
• Are there missing members? Did they join the room recently?
• Any missing "x joined/left the room" events at the timeline's bottom?

If that helps, you can do this to get the number of loaded members in Mirage:

• Press F1 to open the debug console
• Type ModelStore.get("@your_user_id:example.org", "!theRoomId:example.org", "members").count. You can quickly copy the user and room ID by right clicking on your account and the room in the left panel.

from mirage.

My guess about the user count is totally wrong. The number of users varies. The server I'm on, is quite new, so there are still no kicked/banned for now. It seems Mirage misses some invitations. I think it should show them, right? I saw it doing it. Edit: It looks like it only happens in non-encrypted rooms. The encrypted ones don't show the invitations.

from mirage.

encrypted rooms do show invited user though ?

from mirage.

It does not show all of them sometimes. There are some invitations missing. I looked at Element in the web browser. I guess I have to find a way to reproduce it.

from mirage.

Can you still reproduce this in 0.6.2? Make sure you have matrix-nio 0.15.1.

from mirage.

invites still don't show up in encrypted rooms, which is what causes the bug seemingly, but as of yet i haven't gotten a membersyncerror

from mirage.

The invite bug has been fixed in poljar/matrix-nio@560a4a0
