--- Begin Message --- Subject: 24.4; Bug in auth-source.el's search of OS X Keychain Date: Sun, 16 Nov 2014 20:04:42 -0800
The library `auth-source.el' contains code to search OS X's Keychain
(the backends `macos-keychain-generic' and `macos-keychain-internet').

Both backends are implemented by parsing the results of OS X's
/usr/bin/security. This parsing is done by
`auth-source-macos-keychain-search-items'. However, there's currently a
problem with this code in both the master and emacs-24 branches.

Specifically, the function `auth-source-macos-keychain-result-append' is
called three times, but each time its result is ignored.

A precise recipe from `emacs -Q' is a little difficult, because it
depends on OS X and what you have in your keychain. However, the below
is an example of what will work with the fix but not with the current
code.

A simple patch (against the emacs-24 batch) is attached. I don't yet
have paperwork on file with FSF, but I believe this is short/trivial
enough to be accepted anyway.

    ;; Example. With appropriate user/host, will be nil before patch but
    ;; return expected output after patch.
    (progn (require 'auth-source)
           (auth-source-macos-keychain-search
            :backend (auth-source-backend-parse 'macos-keychain-internet)
            :user "MY-USER"
            :host "MY-HOST"))

Thanks, applied to emacs-24 branch as a bugfix:

commit a10e36a5d7fe95830e3f93dc7ae6f65507738978
Author: John Mastro <address@hidden>
Date:   Wed Nov 26 09:15:08 2014 -0500

    auth-source: Fix Mac OS X keychain lookups.
    
    * auth-source.el (auth-source-macos-keychain-search-items): Return
    result of `auth-source-macos-keychain-result-append' (bug#19074).

It will eventually get ported to Emacs master and to Gnus master as
well.  Glenn or Stefan, should I do that or wait for you?

Thanks!
Ted
