24.3.50; Hang with X11 + emacsclient |

Notmuch/0.17+171~gbc10f63 (http://notmuchmail.org) Emacs/24.3.50.2 (x86_64-unknown-linux-gnu) |
I observe strange hangs when using org-protocol via emacsclient, under
X11. Recipe to reproduce:
1. emacs -Q (recent trunk version; I’ve been seeing the bug for several
weeks if not longer)
2. M-x server-start
3. touch ~/test
If I invoke the following command from a shell on the same X11 virtual
desktop as emacs, it works fine:
emacsclient ~/test
However, if I invoke the same command from a terminal on another
desktop, the CPU usage spikes of both emacs (to ~50%) and the X server
process (to ~85%), as visible in top. emacsclient prints "Waiting for
Emacs..." to the terminal, and does not exit.
The processes will stay in this busy hang until I switch to the virtual
desktop with the emacs frame on it, at which point the file will open in
emacs. (I suspect that the file does not open earlier, as sometimes I
can see a brief glimpse of the previous buffer when switching to emacs’s
desktop, before the buffer called for by emacsclient replaces it.)
I can then edit normally and exit the server buffer normally with C-x #
causing the emacsclient to exit in the terminal window.
Possibly relevant software versions:
- Arch Linux
- X.org server version 1.15.0-5
- Window manager = a devel version of xmonad (most recent commit is:

XMonad does not make the Emacs frame visible, so Emacs gets stuck in an
endless loop. Many other wm:s change the desktop to the desktop where Emacs
is, but XMonad does not.
Possible we could force that with some EWMH-hints, but the XMonad
documentation suggests that a user may configure XMonad to ignore those anyway.
Se the best we can do is to prevent the endless loop. I have checked in a fix
in the emacs-24 branch.
