Open Dialgatrainer02 opened 9 months ago

Dialgatrainer02 commented 9 months ago

i can copy fine but trying to pipe into wl-copy hangs forever including the example ls ~/Downloads | wl-copy

what logs can i provide and how do i get them?

Hi!

i can copy fine

Do you mean that wl-copy some text works fine for you, and only hangs when you pipe something into it? Does wl-paste work?

Does the thing you're copying appear in the clipboard despite wl-copy hanging? What distro, Wayland compositor, and version of wl-clipboard is this on?

what logs can i provide and how do i get them?

The Wayland debug log, which you can get like this:

ls ~/Downloads | WAYLAND_DEBUG=1 wl-copy 2>/tmp/wayland-debug.log

and the strace log:

ls ~/Downloads | strace -f wl-copy 2>/tmp/strace.log

yes i can copy and i can paste it only hangs when trying to use clipboard history with dmenu

ls ~/Downloads | WAYLAND_DEBUG=1 wl-copy 2>/tmp/wayland-debug.log

i ran this and hyprland crashed

ls ~/Downloads | strace -f wl-copy 2>/tmp/strace.log

strace.log

when i copy without piping it work and shows in cliphist however piping something in hsngs untill i ctrl c it

That certainly sounds like an issue with Hyprland, you should report the crash to them.

strace.log

That looks like wl-copy is waiting for xdg-mime, which is waiting for xprop, which is waiting to connect to X11 (likely Xwayland). Why it needs or uses xprop on Wayland, I don't know.

Are you able to run xprop without it hanging? Are you able to run xdg-mime (e.g. xdg-mime query filetype /etc/os-release) without it hanging? If no, that's where your issue is. You should be able to work around this by specifying the MIME type explicitly, like so: ls ~/Downloads | wl-copy --type text/plain

xdg mime hangs
with --type it works fine this is a fresh arch install so im unsure why xdg mime is hanging but thank you for the fix

I'm also having problem here, but I'm not so sure it is xprop's fault. Looking at the code, xdg-mime uses xprop in the detectDE function to figure out the current running Desktop Environment. It does so using XDG_CURRENT_DESKTOP first, which is set in my DE (GNOME), so it woldn't need to touch xprop here. Also, xdg-mime runs really fast when used directly:

Weirdly, it seems like CPU time is really low (less than 50 ms), but somehow the running time varies wildly, from 2 seconds up to 1 minute.

Logs

I can't run strace without sudo on my system, so here are the Wayland logs.

In emacs | runs the command shell-command-on-region. Guaranteed to hang when piping into wl-copy. P.S., https://www.emacswiki.org/emacs/CopyAndPaste#h5o-4 says something about this.
