Sure, that sounds doable. 👍

I’m up for testing those packages. Would Github allow you to attach a deb to a comment here (perhaps wrapped in a Zip file)?

Yup, it’s working now, thanks @ivaradi! Installed the -dbgsym packages and reproduced the segfault, here’s the gist.

(TBH, I’m just cargo culting from the wiki here, so I have no idea if this result is useful, but I do have a fairly solid way of triggering the issue, so just let me know if I should do something differently.)

I tried enabling the main/debug component for the PPA, but it just results in a bunch of ”repository […] doesn’t have the component ’main/debug'” errors when I run apt update. Should I open a separate issue about it?

This hasn’t manifested itself in ages anymore, so it’s probably fixed.

Summary

Mobile devices receive ”ghost” notifications for already read messages, when set to receive notifications ”when Away or offline”, and receiving user is set to be Away.

Steps to reproduce

1. Set ”Mobile Push Notifications” to ”Trigger push notifications when”: ”Away or offline” (and send ”For all activity”)
2. Using web interface on desktop, set your status to Away
3. (Still in the web interface) receive a message in the currently open channel (which immediately marks it read)

Expected behavior

Nothing happens on the mobile device (no notification).

Observed behavior (that appears unintentional)

The mobile device receives a notification about the already read message. The notification immediately disappears. If you weren’t looking at the device, you’re left wondering why it alerted you.

Other info

If your status is set to Online instead of Away (at step 2), the mobile device receives no notification (as expected). If ”Trigger push notifications when” is set to ”Online, away or offline” (at step 1), the mobile device receives no notification irrespective of your Online/Away status (also as expected).

Environment Information

I’m self-hosting Mattermost 5.26.1 with self-hosted MMPNS 5.22.4. Mattermost Mobile is at version 1.34.0. My mobile devices have Android 10 (Samsung) and Android 7.1.2 (LineageOS 14.1).

I don’t know if this is an issue with the client or the server; I can re-report against the latter if appropriate.

Updated client to 3.0.1 and the issue persists.

Expected behaviour

Selecting ”open main dialog” from the client menu brings up the main dialog.

Actual behaviour

Selecting ”open main dialog” from the client menu either does not bring up the main dialog, or brings it up only to have it disappear almost immediately. The location of the main dialog, when it does pop up, also seems random: sometimes it pops up in the top left corner of the scereen, sometimes at the center of the screen, sometimes right where the tray menu is.

If I’m quick enough to bring the mouse cursor over the main dialog when it pops up, the window seems to stay, until I take the cursor out of it, at which point the window disappears.

The settings window does still open as normal when selected, and works without issues.

Steps to reproduce

1. Select ”open main dialog” from the client (”tray”) menu

Client configuration

Client version: 3.0.0-20200821.171045.ff175088a-1.0~focal1

Operating system: Ubuntu 20.04, Wayland

OS language: Finnish

Qt version used by client package (Linux only, see also Settings dialog): Don’t know where to find that. The settings dialog only says ”Version 3.0.0 (Ubuntu)” AFAICT.

Client package (From Nextcloud or distro) (Linux only): Don’t understand the question.

Installation path of client: /usr/bin/nextcloud

Logs

The client debug log from the time of trying to open the main dialog shows this:

Having shot myself in the foot by rewriting already pushed history, it occurred to me that perhaps I could have the commits list in interactive rebase reflect the commits’ push status in color. If lines of commits that I’ve already pushed to a remote were colored red (or any sufficiently differentiating color), I might actually notice when I’m about to screw up again.

To illustrate what I mean, here’s a mockup I made. This is what it would look like if this was my commit history, and 8b0ce7b was the last commit I had already pushed to a remote:

I have no previous experience in modifying syntax highlighting code, and I have no idea if what I’m suggesting is even possible with vim, so I figured I’d open this request first in case it’s a silly idea, or conversely, if you deem this useful enough to implement yourself.

For future reference, this was probably Ubuntu bug #1875558 (”libproxy1-plugin-gsettings triggers a lot of warnings”).
