The socket is not connected

[HarHarLinks]

I just installed keepass-natmsg from AUR and connected it to KeePassXC-Browser. After a short time (presumably the auto-lock time I configured in keepass hit), I got an error popup: The socket is not connected. Further info was copied to the clipboard:

Keepass didn't close, but was stuck in a non interactive state. I checked $XDG_RUNTIME_DIR/KeePass, which was empty. After a restart, the same directory contains KeePassIPC-9Bcig1wF-BC-P-61504.act and KeePassIPC-9Bcig1wF-Mutex-KeePassAppMutex.tmp.

The issue repeats when locking the DB per timeout or manually. I am using Arch Linux 5.10.8-arch1-1 with wayland/wlroots/sway/xwayland (stable non-git versions).

sorry for taking so long to get back to you one this issue!

does this only happen after you have closed the browser? or does it not matter if the browser is closed or not? regardless, i believe i know what the problem is and will fix it when i have some free time.

thanks for the detailed report!

[HarHarLinks]

No worries :) Doesn't matter whether the browser is running. Thank you for supporting this plugin!

[HarHarLinks]

This continues to be an issue.

[smorks]

do you see a file called $XDG_RUNTIME_DIR/kpxc_server ?
or possibly /tmp/kpxc_server ?

[HarHarLinks]

I currently have the browser extension "KeePassXC-Browser" Version 1.7.9.1 installed as well as keepass 2.48.1-1.
I don't have keepassnatmsg currently since it crashes my keepass, but I can install it if you need me to for debugging.

Currently neither of the kpxc_server files exist.

"/run/user/1000/kpxc_server": No such file or directory (os error 2)
"/tmp/kpxc_server": No such file or directory (os error 2)

[smorks]

ok, understandable. i'll do some testing myself on linux, and i'll let you know what i find.

[HarHarLinks]

Sounds like you fixed it 👍
Will you provide a (pre-)release binary with the fix?

[smorks]

i should have a release out in the next few days. if i get too busy to finish what i want in it, i'll put out a pre-release binary for you.
