address@hidden: emacsclient --eval has slightly counterintuititve behaviour.]

[Richard Stallman]

I think this is a bug--emacsclient should at least terminate.  Would
someone like to fix it?

Subject: emacsclient --eval  has slightly counterintuititve behaviour.

I've noticed something which may be a bug in the  -eval command in the
handling in the emacsclient/server. 

Summary: "emacsclient --eval" never returns if the passed elisp string
is invalid or fails. 

Version:  CVS (as of today) 

Example: 
emacsclient.emacs-snapshot --eval some_invalid_elisp

emacs *Messages* report: 
error in process filter: Symbol's value as variable is void:
some_invalid_elisp

(which is to be expected) 

emacsclient then sits there indefinitely trying to read from the server
socket. 

Expected result: at the very least emacsclient should return, at best
return with an error. 

Is there ever a way for an lisp expression invoked from emacsclient  to
write stuff back to emacsclient?  If not then having --eval -->
- --no-wait in emacsclient would be sufficient to solve the problem. 

(although i think making the server always respond with at least a empty
write when it is invoked without -nowait is the polite thing to do)
