Subject: 24.5; auth-source-search ignores netrc entries with port set
Date: Wed, 16 Dec 2015 21:42:26 +0100

The auth-source-search function ignores .authinfo entries which contains
port if port is not specified in the search.

Steps to reproduce:

1) Create a file "~/test.authinfo" with the following contents:
machine mymachine1 login user1 password pass1
machine mymachine2 login user2 password pass2 port 100
machine mymachine3 login user3 password pass3
machine mymachine4 login user4 password pass4 port 200

2) Perform in *scratch* buffer to set this file as a auth source
(require 'auth-source)
(auth-source-forget-all-cached)
(setq auth-sources '("~/test.authinfo"))

3) Run the following:
(dolist (account (auth-source-search))
  (print (plist-get account :host)))

Output:
"mymachine1"

"mymachine3"
nil

4) Run the following:

(dolist (account (auth-source-search :port 100))
  (print (plist-get account :host)))


Output:
"mymachine1"

"mymachine2"

"mymachine3"
nil

5) Run the following:

(dolist (account (auth-source-search :port 200))
  (print (plist-get account :host)))

"mymachine1"

"mymachine3"

"mymachine4"
nil


Expected result:
In step 2 the auth-source-search function should return all 4 machines
In step 3 the auth-source-search function should return only machine2
In step 4 the auth-source-search function should return only machine4

Technically, you cannot expect more than 1 result, if you don't
specify :max (it defaults to 1).  But that doesn't mean the bug you
report isn't real: it is.  What happened was that the function that
parsed the netrc entries would reject any entry which had a port
specified.

This is now fixed on the emacs-25 branch, in commit 9384953.

Lars, I hope it's okay to fix something in Gnus in the Emacs
repository?  I assume you will synchronize with your repo.

Thanks.

Katsumi Yamaoka does the synchronizations bidirectionally. I can confirm
this bugfix was synchronized.

Alexey, can you confirm the bug can be closed?

Hi,

The bug itself is fixed. However the behavior when port specified is
still strange. Given the same test case, the 

(dolist (account (auth-source-search :port 100 :max 999))
  (print (plist-get account :host)))

returns

"mymachine1"

"mymachine2"

"mymachine3"

Therefore all machines without ports and the one with the correct
port. I assume there should be only one result returned, the machine
with the proper port.
More, if we specify the port which doesn't exist in the list:

(dolist (account (auth-source-search :port 150 :max 999))
  (print (plist-get account :host)))

returns

"mymachine1"

"mymachine3"

- all machines without ports in test.authinfo.

An entry without port is matched by any port.  In general, an absent
specification means any.

Exactly :)

The only tricky case is explained in (info "(auth) Help for users")

   The typical netrc line example is without a port.

     machine YOURMACHINE login YOU password YOURPASSWORD

   This will match any authentication port.  Simple, right?  But what if
there’s a SMTP server on port 433 of that machine that needs a different
password from the IMAP server?

     machine YOURMACHINE login YOU password SMTPPASSWORD port 433
     machine YOURMACHINE login YOU password GENERALPASSWORD

I hope that helps. Closing this as done, but please let me know if the
auth-source manual or docstrings need improvement.

Thank you
Ted

The return values are hopefully sorted by specificity, right?  So the
first entry will be 433 if you specify :port "443" in the auth-source
call?  (And :max 1 will just return that entry...)

They are in the order they're found, yes.

Ah, so the order of the entries in the .authinfo file matters...
