I don't know if the menuerror in pyxdg is a red herring, but related: https://gitlab.freedesktop.org/xdg/pyxdg/-/issues/18. Of note, I did manage to get #87985 running once, but I have not since been able to get it running again.

bbjubjub2494 commented 4 years ago

This can be reproduced by running in a nix-shell

from xdg.Menu import parse
parse()

So this is a pyxdg bug independent of Xpra.

bbjubjub2494 commented 4 years ago

Reduced further to

from xdg.Menu import MenuEntry

directory, d = 'kf5-unknown.directory', '/run/current-system/sw/share/desktop-directories'
menuentry = MenuEntry(directory, d)
menuentry.Type  # AttributeError

Will get in on it on gitlab.freedesktop.org

@lourkeur Related issue mentioned on the xpra bugtracker

mjlbach commented 4 years ago

Managed to get it running on KDE randomly... Wondering if it has something to do with startup, here's the journalctl when I can vs can't use xpra without the xdg error.

journalctl_on_success.log

journalctl when xpra won't launch.log

Ok, even stranger, if I start or run xpra over ssh to my computer, the problem goes away (although intermittently the menu does not appear on applications). Totaam has added a workaround in the soon to be released xpra 4.0.2 http://xpra.org/trac/changeset/26442/xpra

mjlbach commented 4 years ago

Ok, it's definitely something in the XDG variables. If I run this shell script, xpra starts even on KDE. Since we're not having this problem on gnome, it must be some difficulty with the XDG variables set by KDE that pyxdg is having difficulty with.

Variables which work:

export XDG_CONFIG_DIRS=/etc/xdg:/home/mjlbach/.local/share/flatpak/exports/etc/xdg:/var/lib/flatpak/exports/etc/xdg:/home/mjlbach/.nix-profile/etc/xdg:/etc/profiles/per-user/mjlbach/etc/xdg:/nix/var/nix/profiles/default/etc/xdg:/run/current-system/sw/etc/xdg

Ok, even stranger, if I start or run xpra over ssh to my computer, the problem goes away (although intermittently the menu does not appear on applications). Totaam has added a workaround in the soon to be released xpra 4.0.2 http://xpra.org/trac/changeset/26442/xpra

We can even (fetchpatch https://xpra.org/trac/changeset/26442/xpra?format=diff&new=26442), that's nice.

mjlbach commented 4 years ago

I bumped xpra to 4.0.1 in a PR, so that should apply cleanly (I can do that in a bit).

I'm still concerned about what's going on with XDG. It seems all that is necessary to "fix" the problem is to override the XDG_DATA_DIRS

export XDG_DATA_DIRS=/home/mjlbach/.local/share/flatpak/exports/share:/var/lib/flatpak/exports/share:/home/mjlbach/.nix-profile/share:/etc/profiles/per-user/mjlbach/share:/nix/var/nix/profiles/default/share:/run/current-system/sw/share

I'm contemplating just bisecting the envvars to see what is causing the issue... It would be great if it's an upstream problem, but I wonder if something about nix is exposing that.

Ok, I updated the PR to include a patch (just dumped the file in for now). I also made this issue about pyxdg (managed to isolate which envvars cause the issue) https://github.com/NixOS/nixpkgs/issues/88593.

mjlbach commented 4 years ago

Closing, because technically fixed in master by #89570, although we should do the version bump to 4.0.2 anyways and the backport to 20.03
