bug#41910: 26.3; xclip (wl-copy/Wayland) doesn't copy from Emacs Client

[emacs]

Hello,

I'm using xclip 1.10 under Wayland and I use `wl-clipboard` [0] to copy

and paste.



When I connect a client to the Emacs daemon, I cannot copy text from a

buffer to outside Emacs (be it a GTK application or another shell). To

copy and paste text from a buffer:



- I start selecting text with `C-space` then arrow keys to extend the
selection

- I copy the selection with `C-w`

- I paste the selection outside Emacs with whatever works (shift+ctrl+v,

- shift+ins, ctrl+v, ecc.)



If I start `emacs` directly the above workflow works just fine.



I've hacked a bit `xclip.el`, seems that these commits [1] and [2] are

related to the issue. If I revert to using `process-file`, I can copy
again also from

an attached Emacs client.



Regards,

Please tell how you invoke emacsclient in those cases.

Also, if you disable xclip and don't use wl-clipboard, does the
problem go away?

Thanks.

Hello, thanks for the reply.

> Please tell how you invoke emacsclient in those cases.

I use this alias:

alias em='emacsclient -t'

> Also, if you disable xclip and don't use wl-clipboard, does the

If I start emacs in Fundamental mode (emacs -q) which I believe should
disable any package, I observe:

- I cannot copy from Emacs and paste into a GTK application
- I can copy from a GTK application and paste into Emacs
- Yank and Kill-ring-save work inside Emacs

Hope it helps, sorry if my wording is not correct, feel free to ask more
details.

"emacs -Q" will disable all local customisations, but "emacs -q" will
let some through.

I'm unable to reproduce this in Emacs 27.2/28 -- what GTK application
are you pasting into, and how are you doing it?  (Marking a region with
the mouse in Emacs?)

Hi, thanks for the reply. I can't provide a reproducible anymore 
as now I use a
completely different Emacs configuration (Doom) and don't use
emacs server/client configuration.

Best,

OK, I'm closing this bug report, then.  If further progress can be made,
please respond to the debbugs address and we'll reopen.  (Or file a new
bug report.)
