 x-get-selection: Timed out waiting for reply from selection owner
Date: Mon, 17 Mar 2014 08:49:09 -0600

I'm using a recent-ish emacs trunk on x86-64 Fedora 20.
Whenever I try to paste using the middle mouse button, Emacs freezes.
After a time it comes back and gives the error:

x-get-selection: Timed out waiting for reply from selection owner

Seems like easiest way to reproduce it is to run any command that touches
primary selection, for example:

(shell-command "xclip -o -selection XA_PRIMARY")

freezes whole emacs until Ctrl+G but with XA_CLIPBOARD it works as intended

This is not the same.  This hangs because of a deadlock.  Shell runs synchronous, and hangs until the command output has been read.  But when emacs does that, it can’t respond to the request from xclip.
It also only hangs if Emacs owns the primary selection, not if another process does.

It is because there is a clipboard handler running, i.e. Emacs does not answer to xclip in this case.

Thanks for tracking down and diagnosing this bug.  I've installed a patch as 
commit 1552e6737317ea2c85e06600e178114c6b0f9fb2 in emacs master; can you please 
try it in your environment?

It's possible, I suppose, that this fix will affect Bug#13486 and Bug#17026 
(merged with Bug#16737, Bug#17101, Bug#17172, Bug#19320, Bug#20283).  Ideally 
those bugs would go away too, though this is a shot in the dark.  Anyway, I'll 
CC: to those bug reports to give their followers a heads-up.

Thanks for looking into this.  But it doesn't build as it is in the

The output of gcc -E for the corresponding part is:

        struct input_event *hold_quit)
{
  union buffered_input_event *ev = (union buffered_input_event *) event;

  return kbd_buffer_store_buffered_event ((union buffered_input_event *) event,
       hold_quit);
}


If I comment out the line for the "verify" macro, the it successfully
builds and runs without crash.

Thanks, it appears I was assuming C11 semantics that clang doesn't support.  I 
installed the attached further patch, which worked for me with clang 
3.6.0-2ubuntu1 (Ubuntu 15.04).

It now builds and works for me, too.  Thanks again.

I haven't seen this since moving to Emacs from git a week ago, so the
bug is definitely gone.  I assume it was your patch.  Thanks!
