Linux app doesn't seem to quit properly

#1
  • Operating System (Platform and Version): Ubuntu 18.04
  • App version (at Preferences > About): Aether Community Edition v2.0.0-dev.13, build 1906191901.7eaf250

Expected Behavior
Either:

  • Aether and all its associated processes should actually quit when I click the Quit menu item, or
  • some indication that there are background processes running should stick around, assuming they do something like talking to other peers that I might want to disable (e.g. on a metered network)

Actual behavior
Two processes keep running in the background after I quit Aether.

To Reproduce

  • open Aether

  • close Aether (tray icon → Quit)

  • $ ps aux | rg aether
josh     15616  1.3  1.1 263604 192600 ?       Sl   19:24   3:05 /snap/aether/x1/resources/app/aether-frontend-linux-x64 run --isdev=false --clientip=127.0.0.1 --clientport=40243
josh     15622  0.1  0.6 196592 101208 ?       Sl   19:24   0:17 /snap/aether/x1/resources/app/aether-backend-linux-x64 run --adminfeaddr=127.0.0.1:45001 --adminfepk=[redacted]
josh     20731  0.0  0.0  29832  7448 pts/1    S+   23:07   0:00 rg aether

    The argument to --adminfepk is a long hex string, which I’ve redacted out of an (over)abundance of caution.

hm, maybe I was just impatient – they’re gone now. Wonder what exactly they were waiting for…

#3

It doesn’t do anything special, the SIGQUIT handling is not any different from any other binary. It might just be that if it had a lock on a file (likely the db) it could have been finishing its write task before the quit.
