Subject: 23.3; Gnus - eudc/ldap - inline expansion does not work
Date: Tue, 10 Apr 2012 10:49:24 +0200

#v+
I configured Gnus for search adresses  in my ldap directory.
When I query via form it works perfectly.
But when I try to use inline expansion[1] it does not work and I got:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (error "No match")
  signal(error ("No match"))
  byte-code("           <---------snip here-------------> " [eudc-server
  eudc-former-server eudc-protocol eudc-former-protocol signal
  eudc-set-server t] 4)
  eudc-expand-inline()
  message-expand-name()
  message-tab()
  call-interactively(message-tab nil nil)
--8<---------------cut here---------------end--------------->8---

Stracing shows  that ldapsearch is called (once), and fills some files
with
values. These files are then read by emacs. 
[1] - by writing first/last name  and then pressing tab.

Can you load the uncompiled version of eudc.el (maybe of all the
eudc*.el files), and post the backtrace that you get in that case?

I'm afraid that's not much more informative. There are some variables
you can set so that the lists don't get abbreviated, but I forget
precisely which ones they are. Anyway, a full backtrace probably isn't
going to help too much. All that happens is that it fails to find a
match for some reason.

I'm afraid I have no idea how to configure eudc so that I can test this
myself, and I don't have any ldap servers to test it with anyway.

If you can use edebug, you might try looking into this more yourself.
If as you say it works in other contexts, then the problem may be
something simple like it not extracting the correct string from the
buffer in the first place.

I noticed by accident that it related to 
(eudc-inline-expansion-format)

with its default setting 
--8<---------------cut here---------------start------------->8---
("%s" email)
--8<---------------cut here---------------end--------------->8---
inline expansion seems to work 
But i prefer to expand entries to something like  

--8<---------------cut here---------------start------------->8---
Kamil Jońca <kjonca <at> gmail.com> 
--8<---------------cut here---------------end--------------->8---
and with setting ("%s %s <%s>" firstname name email) 
this does not work.
Am I missing something with setting this variable?

Can you try running ldapsearch on the command-line, with the same
arguments that you see in the strace output?

One possibility is that the server is returning results that contain
LDAP attribute names that Emacs is not expecting.

The relevant code is in lisp/net/eudc.el:

   [...]
   ;; Loop on query-formats
   (while query-formats
     (setq response
           (eudc-query
            (eudc-format-query query-words (car query-formats))
            (eudc-translate-attribute-list
             (cdr eudc-inline-expansion-format))))
     (if response
         (throw 'found response))
     (setq query-formats (cdr query-formats)))
   [...]

If I hard-code a wrong value list in place of:

   (eudc-translate-attribute-list
    (cdr eudc-inline-expansion-format))

(I tried '(givenname sk mail)), then inline expansion fails with "No
match", but form expansion still works.

eudc-translate-attribute-list converts the inline expansion format based
on the attribute values in eudc-ldap-attributes-translation-alist:

   (defvar eudc-ldap-attributes-translation-alist
     '((name . sn)
       (firstname . givenname)
       (email . mail)
       (phone . telephonenumber))
     "Alist mapping EUDC attribute names to LDAP names.")

See if there are differences between sn, givenname, and the attribute
values you see in the command line output.

Hi,

I'm closing this because I haven't heard back how to reproduce it.
Please reopen the bug if you can provide more information and/or do the
experiment I mentioned in my last follow-up.

Thanks,
Thomas
