Some issues with new nnimap

[Drew Hess <drew.hess@gmail.com>]

Hi Lars,

I'm really happy to see you working on Gnus again. Thanks for a great
mail reader!

I'm having a few issues with the new nnimap backend. Here's my server
definition:

(setq gnus-select-method '(nnnil ""))
(setq gnus-secondary-select-methods
      '(
        (nnimap "imap.bothan.net"
         (nnir-search-engine imap))))

Without a .authinfo file, I'm unable to login. The login process
appears to hang after the IMAP server sends its greeting. Here are the
contents of my *nnimap.. buffer:

---

I looked through the mailing list and this appears to be similar to a
problem someone else was having, which you chalked up to a race
condition and fixed with commit
3a31df78354f7ddba9a08aed8f1a5e180f1ab032, I believe.

So then I created a .authinfo.gpg file. I'm using EasyPG with
(epa-file-enable) in my .emacs, and I'm able to open this file in a
new buffer seamlessly, but when I try to connect to my IMAP server,
I'm just repeatedly asked for my GPG passphrase. I'm certain I'm
typing it correctly. Here's what my *Messages* buffer looks like when
this happens:

/Users/dhess/.authin: 100% (655/655)
/Users/dhess/.authin: 0% (0/655)

This continues until I hit C-g to abort, at which time Gnus gives up
trying to connect.

Finally, if I just create an unencrypted .authinfo file, everything
works fine:

There's only one catch: every time I hit 'g', Emacs beeps at me. All I
get in the *Messages* buffer is this:

---
Checking new news...
Reading active file from gnus-help via nndoc...
Cannot read active file from nndoc server
Reading active file via nndraft...done
Checking new news...done

The groups are refreshing properly, etc., so it's not strictly a
problem, it's just annoying. I didn't have this issue with bundled
Gnus.

FYI, I'm running Emacs 23.2 with YAMAMOTO Mitsuharu's Mac patches. I'm
willing to try this with stock Emacs 23.2 if you think it might be
related.

thanks again!
