More IMAP testing, please

We got a fair amount of nnimap testing and bug stomping yesterday, but
I'm sure there must be a lot more problems hiding here and there, so
it'd be great if more IMAP users took the plunge and gave the new nnimap
a whirl and report problems (or whether it works fine for your).

To all the fence sitters: it now works for me with a single dovecot and
agent.  And it is a _lot_ faster than the old version.  Especially at
startup and on `g' (it may be that there are other speedups here, in the
way gnus now scans groups over multiple servers.  I have a single nnimap
and 3 or 4 nntp servers, all agentized).

I'm obviously doing something stupid here...

I've downloaded the git repository, compiled the lisp, added it first in
my load-path and set up a gnus-secondary server using ssl. When I start gnus,
sometimes I get server denied and sometimes not. I've tried debugging
nnimap-open-connection when it fails, and I get this:


Unable to open server nnimap+test due to: Symbol's function definition is void:\
 setf


But why sometimes and not others? I would have thought that either setf
is defined at compile time or its not. And why doesn't anyone else have
this problem? My .emacs only has the load path and (require 'gnus-load)

I just tried it with imap.web.de which did not work with the old
nnimap.el.  There should be some messages about web.de in the ding
archives.  IIRC the problem has been due to the article numbers being
very large on this server.

With the new code I could actually see the contents of my INBOX.  It had
about 20-something mails with ads and one legitimate one which was the
newest.  After deleting the ads and reading the legitimate mail I left
the group and tried to enter it again while asking Gnus to show me the
last 11 mails.  That's when it went nuts. (c:  While using 100% of the

Okay I tried this again and got the following backtrace with
`debug-on-quit' enabled, when I interrupted the loop:

        It is working fine for a gmail account and a Courier-IMAP server

I previously used a test account and only now tried to switch my real
Gnus. However it silently fails:

Opening TLS connection to `ltw.loris.tv'...
Opening TLS connection with `gnutls-cli -p imaps ltw.loris.tv'...failed
Opening TLS connection with `gnutls-cli -p imaps ltw.loris.tv

Opening TLS connection with `openssl s_client -connect
ltw.loris.tv:imaps -no_ssl2 -ign_eof'...done
Opening TLS connection to `ltw.loris.tv'...done
Couldn't open nnimap:ltw

First: Shouldn't the user get a message that opening the server failed?
I can only see in server buffer that status is denied, but neither
during start up nor in Group buffer is the failed state visible.

How do I debug this? I have a buffer named
*nnimap ltw.loris.tv nil  *nntpd**
With the text

2 BAD Missing '"'^M

The first time you run it, it does a total flag rescan.  Subsequent
times it does partial flag rescans, so it'll only be slow the very first
time you use it.

Yes, the error should be more noticeable, but I'm not sure how to do
that without annoying users.  Most of us have, I'm sure, a server or two
in Gnus that don't respond.

Have a look in the *imap log* buffer to see what it's trying to send.
From the look of the error message, it might be a quoting issue.

Ah, OK. First startup easily took 30 seconds or so. I think a message
like 'Don't hit C-g just yet I'm doing serious work here' would be helpful.

Still, while entering/reading articles is way faster, 'g' is a tad
slower than it used to be, at least for me.

Oh, and hitting 'A T' yields "gnus-summary-refer-thread: Can't fetch
thread from back ends that don't support NOV". I'm pretty sure this used
to work...?

That's definitely a possibility.  But it might be something else.  If
you `C-g' out of the question, what's in the "*imap <server> ...*
buffer?  (There might be more of them -- find the most recent one for
the server in question.)

Yup.

What's your setup?  Many different IMAP/nntp servers, or just one?  And
how many IMAP mailboxes?  And what's the IMAP server type?

Heh.  Hadn't thought about that one.  Yes, nnimap no longer serves out
NOV headers, since we're getting normal headers from the server, and
first converting them to NOV and then parsing the NOV seemed like waste
to me.

I think the right fix here is to change `A T' so that it works on
non-NOV backends, too.

'g' queries 15 mailboxes on one IMAP server, which is Dovecot Debian
stable via network/ssl on a virtual server. This takes maybe 1 second,
which is not really a problem, but the old code was faster (since it
only did EXAMINE and not FLAG fetching, as far as I remember).

Yeah well, it's not terribly important at the moment.

Oh, and nnmairix is broken with nnimap now since you haven't implemented
nnimap-request-delete-group (yet). ;-)

Well I'm sorry, I should have wrote: I don't have any buffer matching
anything that look like imap/nntp/gnus or anything else. :-(

So they either never existed or they have been destroyed at the time the

So that means that .netrc is parsing the lines kinda wrong.  I think.
Is there a convention for opening files in Emacs that may possibly have
been saved in DOS mode?  Otherwise the netrc.el parsing function may
just want to strip the ^M before parsing.

Yes, the buffers are killed once you exit Gnus, but they should be

gnus-opened-servers is a variable defined in `gnus.el'.
Its value is 
(((nnimap "Mail"
          (nnimap-address "keller.adm.naquadah.org"))
  denied))

So at least I know that the problem is `denied'.

Goin' deeper now…

If a server is marked as denied, that means that it failed to open it.
If you go to the server buffer and say `C' on it to close it, a `g' in
the group buffer should re-request it again.  Probably.  Or just restart
Gnus.

Hm.

Well, try evaling this:

(nnimap-open-server "Mail" '((nnimap-address "keller.adm.naquadah.org")))

and see what happens.  If it returns nil, it means that it thinks that
it couldn't contact the server.

Oh, this means that it's contacted the server, but haven't sent any
login credentials.  Looking at the code, it looks like this would be the
result of nnimap can't find any credentials.  But it should prompt you
in that case.  I'll try to reproduce.

By the way, `C' does nothing on my IMAP server in the server buffer. :-)

In the server buffer of my gmail account, I can see one group for each
Gmail label as expected, but I can't find the groups [Gmail]/Spam and
[Gmail]/Trash which I can see, e.g., with Sylpheed Claws.

Wasn't able to.  But it has to be something in the

No, it's opened right now. But it seems to be a noop:

The [] characters were part of the set Gnus ignored in group names.
I've now removed that -- I don't think it'll break anything in Gnus, and

The stuff in the *nnimap ...* buffers is the same whether you get a nil

That is odd.  nnimap has a

(eval-when-compile
  (require 'cl))

which I thought would do the trick, since setf is from cl-macs, and
isn't needed at run time.

If you do a

(require 'cl)

Yeah, that's not going to work.  Gnus decompresses some of the ranges
before group selection, and when they are big like that, it's going to
totally kill your Emacs (and your machine).

My longer-term plans involve stopping all range
decompression/compression, and working directly with the ranges.  But
that's a rather big undertaking, so it's not going to happen
immediately.  In the mean time, you still can't use nnimap to read
messages from that server.

Re: More IMAP testing, please

[Dan Christensen]

I've just upgraded from a pre-git gnus (Dec 2009, I think) to the latest
git version, and I'm having some problems with my imap groups.  The
server in question is dovecot on localhost:

   '(nnimap "rocky"
	    (nnimap-address "localhost")
	    (nnimap-server-port 143)
	    (nnimap-stream network)
	    ; Summary generation is faster with this t:
	    (nnimap-nov-is-evil t)

My largest group has about 6500 articles, but after a few minutes of
using gnus, gnus would only show me the newest 71 articles (which seem
to be the ones whose article numbers are within 100 of the latest).
`M-g' on the group fixed this, but then I found I had lost *all*
marks on the older articles (tick, expired, answered definitely
lost, read not lost).

This also happened in my Inbox, a smaller group.

This is a very serious problem for me, and I'm happy to provide
whatever information I can to debug it.

A less important problem: for some reason, two of the groups on this
server show up with "*" instead of the unread article count.  I think
these are on the only two groups that are empty.  If I hit `M g', my
summary buffer shows 1 unseen and 1 unread.  But when I try to enter the
groups, gnus notices that there aren't any articles.  After that, `M g'
shows 0 unread and unseen.

Good news:  haven't noticed problems with two nntp servers or with
a remote imap server using "ssh %s dovecot --exec-mail imap", although I
haven't tested either very much yet.

Re: More IMAP testing, please

I have just tried client-side splitting and found one small problem. In

response).

Once I made this change I get mail split, but I haven't yet received

Re: More IMAP testing, please

[Dan Christensen]

I just tried using `B m' to move an article from an nnimap group
to an nnfolder group, and the result was that the following was
appended to the nnfolder file (without the leading whitespace):

  From nobody Sun Sep 19 20:34:21 2010
  Message-ID: <87sk155k36.fsf@totally-fudged-out-message-id>
  Lines: 0
  Xref: rocky cherrington-dejong:1594
  X-Gnus-Article-Number: 1594   Sun, 19 Sep 2010 20:34:21 -0400
  

That's it, no other headers, and just a single blank line after
those headers.

Luckily, the message was also stored on a remote imap server.
Reading it there, I tried `B c' to the same nnfolder group, 
and that time it worked.

Further tests show that this is repeatable:  `B m' fails and
`B c' works.  This has the potential to cause loss of mail.

I have %k in my gnus-summary-line-format, and in nnimap groups, the

I switched last night/this morning. Some remarks and an error:


I have in .gnus

;; Email (Imap)
(setq gnus-secondary-select-methods
      '((nnimap "thuis"
	       (nnimap-address "mail.server.address")
	       (nnimap-stream ssl) ; was tls
	       (nnimap-authinfo-file
		"/home/gijs/.imap-authinfo"))))


and in the Server Buffer, the same list for the server except that
nnimap-stream ssl here mentioned tls, not ssl. (I had changed that
yesterday evening in .gnus) 

This makes gnus do openssl / gnutls for each of my kazillion
mailboxes. That slows the start-up of gnus down significantly....  I
manually killed the openssl stream a few times to get gnus to start so I
could actually edit the server buffer to make these two configurations
the same (replace tls by ssl).

At that point, I noticed the mail.server was in the server list
twice. But that disappeared after the edit, quit and restart.

Now gnus starts *really* fast, and I can get to my mail. 

I enter a mailbox (called INBOX.stilte) , look at some of the mails and
enter q to do something else. I get a "Format specifier doesn't match

It's working fine for me here to my Exchange server (2003, I
think). Only one issue so far: is article deletion supposed to work? I
mark articles with B DEL, but they're still there marked 'O' when I
re-enter the group. Is there some please-expunge-on-exit variable I need
to set?

Regards

Robert

PS 'G x' fails as well, probably because you haven't implemented
nnimap-expunge yet. :)

Here are some numbers to back this up: Running (gnus-group-get-new-news)
50 times takes ~15sec with the old nnimap, ~21secs with the new one. The
interesting bit is that the old code took only ~10 GCs, while the new
one needs ~120, which take ~6 seconds, so that's your time difference
right there.

I forgot to mention that I did test the old nnimap with an older git
checkout, so it's not only nnimap but also all the other code that's
changed in the back end which might add to the GCs.

Re: More IMAP testing, please

[Andrew Cohen]

Now I have received fair number of email messages and can say that
splitting is working fine with the previous fix I sent.

I'm also seeing the previously reported issue with
nnimap-wait-for-response being called with a nil sequence in
nnimap-request-set-mark.

I also saw the problem moving articles (as previously reported) and found
that gnus-find-method-for-group was returning different things for two
groups both on the same imap server. So the nnimap move functions were
not using the internal-move-group code (and I gather that moving between
different servers isn't working yet). I tracked this down to two
different specifications in the .newsrc.eld file. Some groups had

(nnimap "home")

while others had

"nnimap:home"

I changed all instances to the latter (is this the right thing to do?)
and now it works fine.

That's not good.

To take the last problem first, Gnus will only send over updates of
marks when it thinks a mark has changed.  So if Gnus doesn't think that
article 423 has a tick, it won't de-flag the article on the server,
either -- it should only send over updates of articles that has changed
status while in the summary buffer.

I think.

So I don't understand that at all.

The former problem sounds like a parsing problem of some kind, but since
`M-g' is able to parse the data, I'm not sure how to interpret that...

Sounds like an off-by-one error on empty groups.

I'm nervously looking forward to trying it soon.  Mail is my (work) life
and missing reading messages or worse losing messages would be the
death of me.  I'm sure that losing messages on the server isn't likely,
but if I miss seeing one (cause it's not in the summary buffer or, um, or...)
then I'd be in deep trouble.

So, maybe a statement like "the worst that could happen would be ..."

If you don't do client-side splitting, then the worst that can happen is
that you lose article flags, as reported by Dan Christensen.  I haven't
been able to figure out how that could happen, though...

Well, even worse would be it not working at all.  :-)

Well, `B m' loses messages currently.  This seems like the most

I've verified that these flags were removed from the articles on the
server (a total of more than 1000 flags).  And this problem happened
with two different imap groups, at the same time.

All flags except read ("Seen", I think) were removed: Answered, Flagged,
gnus-expire, gnus-save and gnus-forward were the ones that were there.

> The former problem sounds like a parsing problem of some kind, but since

To me it sounds like a problem involving the strategy of sometimes only
getting mark information for the last 100 articles, and sometimes
getting it for all articles.

So far it hasn't happened again, but I'm still in the same emacs session
so I can provide whatever information you need.  I've included an except
from the *imap log* buffer below, and can send more if that would help.
My INBOX has about 80 articles, but many of them are quite old so their
article numbers aren't in the most recent 100 numbers.

This is repeatable, so let me know if there's anything I can do to help
debug it.

Losing flags would suck, but can at least be recovered from.  The
biggest issue is that when I lose flags I have to resort everything.

Now...  if there was just a way to use the new nnimap for some folders,
and the older for some more important ones :-)

I have been doing client-side splitting for 24 hours and it seems to be
working without issues. I haven't lost any mail and it seems to end up
in the right groups. 

It looks like expiry is not yet fully implemented? I send mail to backup
groups after certain time periods and it would be nice to have this
happen.

I have a backup of my .newsrc.eld from before the marks were lost.  Is
there an easy way to use the backup to make Gnus change the marks to
what they should be, and then propagate those changes to the IMAP
server?  It's not critical in this case, but it would be nice to have
them back.

Well, the two behaviours that might be of interest to me personally are:

1. mark deleted and always expunge on group exit.
2. move to a target folder only.

Re: More IMAP testing, please

[Dan Christensen]

There are still some bugs with `B m'.  The most serious one is that if 
I try to use `B m' to move a message from an IMAP group to that same 
IMAP group, then *all* articles in the IMAP group lose their Seen flags,
gnus-expire flags, and maybe other flags too.  I think this sequence 
of commands are the relevant ones, and commands 330 and 331 look
particularly suspicious to me.

There's also another bug, which also existed with the previous nnimap.el
implementation, so I'm used to it, but since you have this fresh in your
mind, I'll bet it's easy to fix:  If I change the marks on an article in
an IMAP group and then do an internal move to another group on the same
server, the new article keeps its old marks.

Bug number three with `B m':  if I process mark a bunch of articles
and try to use `B m' on them, every second one gets moved, and the
rest are untouched.

Coincidentially the ones I use myself.

I `B DEL' out everything I don't want to keep (spam, invoices for paid
bills, etc.), and let the non-ticked articles eventually expire to an
archive group.

Hm... that one I use (or "used to use") a lot.

Perhaps I should hold off using `B m' until theres' an all clear on this

I bet they cover the 90 percent case, and probably even the 99 percent, for
what "most users" of IMAP do.  OTOH, Gnus users are not exactly typical...

The message-id in nnimap-request-move-article is not getting set
properly. There are two issues: 

1. The article headers need to be fetched first, since we may not be
   looking at the article.

2. message-field-value doesn't strip the carriage return at the end.


My elisp is terrible but this seems to work for me. I've changed
message-field-value and I don't know if this has negative consequences
somewhere else.

I'm not sure about that in this case. Given a command with the following
docstring:

  Documentation:
  Delete the N next (mail) articles.
  This command actually deletes articles.  This is not a marking
  command.  The article will disappear forever from your life, never to
  return.

I think a typical Gnus user would expect the article to disappear,
dammit. As would a non-typical one.

Yes.  But it's not that simple.  :-)

For servers that have the UIDPLUS capability, `B DEL' should (and does,
I think?) first mark the message as deleted, and then expunge the
message in question.

If the server doesn't have UIDPLUS, the only way to make messages go
totally away is to do an EXPUNGE on the mailbox.  That will make all
messages that are marked as \Deleted disappear forever.

So what should the default behaviour on non-UIDPLUS servers be?

Sure.  I'm looking at how to make expiry work now...

So nnimap needs the article dates of everything so that it can expire
articles.  "UID SEARCH SENTBEFORE" should do the trick, shouldn't it?
Alternatively "UID SEARCH SINCE", and the delete all the articles not
mentioned by that command.

(-expire-articles-now would, of course, just delete the list of articles
without looking at the date, so it should be a much faster operation.)

I forgot to ask what I wanted to ask.

Do all the common servers implement "UID SEARCH SENTBEFORE", and is it
usable?  That is, is it fast enough to actually be used?

It's normal to EXPUNGE the mailbox every time the user clicks "delete"
on an article?  I think somebody protested when I had the inbox mail
splitting thing do an EXPUNGE on the inbox, or do I misremember?

But `B DEL' is not "delete" is it?  It's "delete this truly and forever"
and in order to do that, IMAP without UIDPLUS needs to do an expunge.

I guess you could temporarily set the other `E' articles to a
gnus-keep-around mark, run the expunge, then set them back...  But
that's hacky.

I don't know if all server implements it, but Dovecot, my favorite,
implements it and make it fast because it has a good indexing function.

I did not test, I can't find the correct syntax for that IMAP command…

I thought expirable articles would be marked with the gnus-expire
flag, not the \Deleted flag, so they wouldn't be affected by an
expunge.  Or am I misunderstanding what Ted meant by `E'?

In general, I'm confused about whether you guys are discussing
total-expire or auto-expire.  I use auto-expire, and I hope that
old articles marked as expirable will be deleted now and then.

It's a bit confusing.  :-)

"Expiry" is a Gnus concept, and doesn't touch the IMAP servers much.
(That is, Gnus stores the mark on the server, but it doesn't understand
it.)

What we're discussing is how Gnus is to delete articles -- either
expired articles, or just plain deleted articles.  The only way to do
that is to mark the articles in the server as \Deleted, and then either
say "UID EXPUNGE", which will, er, delete the articles, or just say
"EXPUNGE", which will delete all \Delete-marked articles in the group.

I'm not sure whether the latter is naughty or not.  It's tempting to do,
because it's so easy, but I have no idea what IMAP users expect to
happen.

This only affects users of older versions of Dovecot of the major
server types in use at present, I think.

I vote for expunge-on-exit, because that matches my expectations, but I
would be fine with expunge-manually as default, as long as there was a
configuration variable or a hook I could use to get expunge-on-exit.

It places an extra burden on every user ("what is that?  should I use
it?") for the sake of the few who don't have UIDPLUS.  Articles marked
as `E' (expirable) are clearly meant to be deleted sooner or later so
doing it sooner is not a problem IMO.

We can also simply require UIDPLUS.  It's 2010 after all.

Lars, do you have a list of supported IMAP servers and capability
strings?  I'm guessing Dovecot and Courier at least?

I don't know of any servers where the new nnimap is confirmed not to
work, except that server that uses UIDs to compute big prime numbers.
And that's more a Gnus issue than an nnimap issue.

Dovecot on Debian Stale doesn't support UIDPLUS.

There's no built-in functionality for that in Gnus directly -- it tries
to only update marks that have changed by comparing what marks existed
when you entered the group, and what marks exist when you exit the
group.  Hm...  perhaps there is a way.  If you enter the group, then
`G E' to edit the group info, and then insert the marks/etc from the old
file relevant to that group, and then exit the group?  Then it's
possible that Gnus will push over the marks...  er...  no, it works the
opposite way.

Uhm.

If you set gnus-newsgroup-replied (etc) to the uncompressed lists from
the old .newsrc.eld, then Gnus will push them over.  But that's not, er,
easy to do.

	  (error "Can't open server for %s" gnus-newsgroup-name))
	(gnus-request-set-mark gnus-newsgroup-name delta-marks))

Ok, it finds the old data from the group info (`gnus-info-marks'), and
then...  What's `list', then?  It's the article list of this type of
marks.  It's set upon group entry, and should be the same as the stored
info.  ...

Aha!

`gnus-adjust-marked-articles' looks at the marks lists, and if the
active ranges indicate that some of the marks refer to articles that no
longer exists, then they remove those marks!

So the cause here must be that the active data is wrong.

What does

(gnus-active "nnimap+server:group")

say for that group?

I think I've fixed this now.  Could you try the following?

(gnus-server-equal '(nnimap "home") "nnimap:home")

If it says t, then the fixed I pushed out now is correct.

Right.  I've had another look at the flags parsing code, and I think

Again, I don't see what articles marked with 'E' have to do with the
expunging problem.  (I read Lars' reply to my last message, and it
confirmed how I thought things worked.)  If I mark an article with E,
and Gnus does a full expunge on the IMAP group, that article will be
fine, since it isn't marked as \Deleted.

So I think it's fine for Gnus to simply do a full expunge when UIDPLUS
is not supported.  It should only affect articles that get marked as
\Deleted (but don't get expunged) by another client, since Gnus doesn't
do that.

(But if I'm misunderstanding something, then let me make it clear that I
*don't* think it's fine for articles marked 'E' to be expired early
just because I do `B DEL' on a different article.  But I don't think 
this will happen.)

I think the thing that tries to make servers unique fails in the
situation where there are two same-named servers with different
parameters.  In that case it should really just open two servers, but
instead it opens one server per group, which is obviously not very
pleasant.  I'll try to reproduce and fix.

Right.  The former is the correct method?  Then (nnimap "home") wasn't a
correct server, but Gnus handled that situation badly.  I'm now

(gnus-active "nnimap+rocky:INBOX")

gives

(5606 . 5645)

(Both with an old copy of Gnus and with a git version from earlier
today.)

It seems like a good safety check would be to never try to adjust flags
on articles outside of the active range.  Then if the active range gets
messed up because of another bug or some corruption, at least the damage
is limited.

But that's not going to help you, since I decided to move all of the
articles from that group to itself, to compress the article numbers as a
way of possibly working around this bug.

However, here's a group that has ~6500 articles in it:

(gnus-active "nnimap+rocky:hha")

and yet I get

(36564 . 36664)

a range of just 101 articles.  So there is something fishy going on.

Yes.  I've now added a quick hack to avoid pruning marks on group entry.

Yes.  Very fishy.  And that "101" number points strongly at the partial
updating code.

If you `M-g' the group, I assume that the `gnus-active' turns into more
reasonable numbers?  And then a `g' will turn it back to 101?

After starting Gnus (git version as of right now):

(36564 . 36664)

After `M-g' on the hha group:

(29919 . 36664)

After `g' in the *Group* buffer:

(29919 . 36664)

So it stays with the extended range.

By the way, it feels to me like there are two mark-related bugs that
I've reported.  The first one is the one where all marks were lost on
articles with numbers more than 100 less than the highest, except Seen
marks.  This happened in two groups (INBOX and hha) at the same time,
and didn't involve me doing anything except entering and exiting the
groups (possibly with prefix args).  I don't know how to reproduce this.

The second one is that whenever I moved an article from a group to
itself, all marks (including Seen marks) were lost.  It's possible
that this only affected articles with numbers more than 100 less than
the highest, but I thought it affected all articles.  This was
reproducible with the version from a day or two ago, but now it appears
to be fixed.

I looked at what you did (the "(setq min 1) thing) and while it might
fix this particular bug, I was actually recommending a more defensive
change:  whenever Gnus is about to sent commands to the imap server,
check whether all article numbers that will be affected are within the
active range.  If not, something has surely gone wrong, and at the very
least those articles should not be touched.

This is defensive in the sense that no matter what bug caused the
problem, at least the damage would be limited.

This has probably been fixed.  Or "fixed".  It's an ugly hack to not
prune any marks according to the active range on group entry.

Why the active range is wrong is something I'm still poking around to
try to find out...

Following the latest changes I'm having a problem with
gnus-group-completing-read. Previously if I typed "Tra" at the prompt
this would complete to

"nnimap+home:Trash"

now it completes to

"nnimap+:Trash"


And on another note---having some problems with expiry which I haven't
been able to track down. I have a group "test" with 900 fairly old
messages. I set an expiry-target of "test.old" and turn on
total-expire. The articles older than 7 days are correctly placed in
"test.old", but then things freeze. I waited half an hour and then gave
up. C-g a few times gets out of it, but now the original group "test"
still has most of the articles that got copied to "test.old" (at least
it seems like a small number have been deleted but most are still
around).

I haven't changed anything in the completion code the last week...  What

Did it say it was doing anything before you pressed `C-g'?  Also
`(setq debug-on-quit t)' and repeat and post the backtrace.

Oops, my mistake. I have two nnimap servers, "home" and "search", and
tabbing now allows me to choose. (Don't know why it completed directly

No. It had finished "expiring" and I presumed it was

I use multiple IMAP clients, and have configured gnus thusly:

  (defun gdt-gnus-move-to-trash ()
    (interactive)
    (gnus-summary-move-article nil gdt-trash-newsgroup))

  (add-hook              
    'gnus-summary-mode-hook
    (lambda ()
      (local-set-key "d" 'gdt-gnus-move-to-trash)))

  (setq gdt-trash-newsgroup "nnimap+work.lexort.com:Trash")

and then 'd' moves an article to Trash, which I have set up as
total-expire.

I suppose there's some notion of in-group-but-marked-deleted, but I
never figured that out, and I've been happy with the above.

Occasionally I do 'B DEL' as well.
Mostly because my macro doesn't play well with seting marks with '#'.

Hm... it sounds like to be safe I should to pull dovecot 1.2.x from
debian backports, rather than wait for a new stable ("squeeze") to pull
it in for me...?

(For new readers: the current debian stable ("lenny") has dovecot
version 1.0.15, which does not support UIDPLUS.  That support came, in
2008 or thereabouts, with version 1.1, back )

The expiry mechanism is the same, whether you use total-expire or
auto-expire, isn't it...?

The way I've understood it, is that if you have
 (total-expire . t)
in the group parameters, then the articles marked with \Deleted will be
affected by the expiry.

Or was that "marked with \Seen"...?  Hm... now I'm confused.
Nah... probably "marked with \Seen".

Anyway, the behaviour I've had with the previous nnimap was that I had
total-expire.  I used `B DEL' to permanently delete stuff I didn't want
to keep, and just let the rest lie there marked with \Seen (I
think...?), and then occasionally expire that over into an archive
group/mailbox. 

For this to work then `B DEL' had to set \Delete, I guess.  And unticked
articles were marked with \Seen.

A bit more info on expiring---the problem happens only when there is a

I don't understand what is going on very well, but at least a couple of

new news. (I have gnus-demon setup to run every few minutes.) I turned
off the demons and tried again and it worked fine. So maybe its possible
that fetch new mail ends up being run in the middle of expiring and
clobbers the nnimap buffer response?

I mentioned this in my bug followup: it used to be marked as \Deleted

I think so far the votes on that behavior are 2 in favor of "just

Nope.  Mostly, "normal" would actually be the "move to trash" case.

OTOH, the IMAP design, *and* implementations, assume that EXPUNGE can be
expensive, and it is usually reserved for things like doing once, not on every
single delete operation.

Well... I now have UIDPLUS, so my vote goes for "just expunge".

The people who may be bitten by this, are probably the Exchange
users...?  They don't have the option of upgrading to a version that

Whatever it is that Lars has implemented up to now for B-DEL works fine
for me (I think that's EXPUNGE every time), and I'm one of the
aforementioned Exchange users.  I have no complaints about the
performance, although I haven't tried it in a group with more than 400
articles.

If it ever turns out to be too expensive, I can always bug you to
implement 'Mark deleted & expunge on group exit' ;)

My office is still on Exchange 2003 and I have no option of changing
that.  I'm sure I'm not the only one in this position.  Since the
current nnimap works with Exchange 2003, it would be a darned shame if
the new and improved nnimap does not.

When expiring, the EXPUNGE is done at the end, after marking all the
messages as \Deleted.

It should work.  We're just discussing whether EXPUNGE should be on by

Sorry, but I still don't understand what you mean, and I'm not sure
where to look to see your bug followup.

Can you explain a scenario in which doing expunge when the user hits `B
DEL' will cause other articles to be removed from the IMAP server?

a) If I have an article marked `E', and do `B DEL' on another article,
my article marked `E' should still be around.  I'm not aware of any
version of Gnus that would put the \Deleted flag on the `E' article.

b) If I run `gnus-summary-expire-articles-now', I would expect that all
articles marked with `E' will get removed from the IMAP server (i.e. get
marked \Deleted and then expunged).  I don't use this much, but the
documentation is pretty clear.  Has something changed here?  And what
does this have to do with `B DEL'?

As far as I know, Gnus never puts the \Deleted mark on an article
without also expunging it, so unless the user uses a different client
to do this, running an expunge should be safe.

If "yours" means me, I don't think that represents my vote, since I
don't see how an article marked `E' will be affected by doing `B DEL'.
I still vote for always doing an expunge, unless someone explains how
that could be a problem.

[My server *has* UIDPLUS, so I'm not affected by any of this, but
I'd like to clear up my confusion.]

If the user has marked oodles of messages as \Deleted via a different
user agent, and not issued an EXPUNGE, then deleting any message from
Gnus in the mailbox will expunge them all.  (In the non-UIDPLUS case.)

Could there still be a problem if the daemon starts fetching new mail,
and while this is happening, Gnus starts expiring articles?  Should 
some data structures be protected by locks?

A related question: when (important) new mail arrives, I have a shell
script that includes:

  emacsclient --no-wait --eval '(jdc-gnus-demon-scan-mail)' --alternate-editor=/dev/null

where jdc-gnus-demon-scan-mail is a function like gnus-demon-scan-mail,
but which scans mail servers only.  (The default function doesn't seem
to restrict to mail servers, despite its name.)

Every now and then I've noticed that Gnus locks up if I'm doing
something exactly when my shell script runs.  This didn't happen with
the old nnimap, but has happened a few times with the new one.

Is there a way to tell emacs to only let an emacsclient instance run
something when the server isn't already running some code?  I had
assumed that this was how things worked by default, since emacs doesn't
have multi-threading.  Ah, the timer node in the elisp manual says that
timers can run when functions like sit-for and read-event are running,
so the same is probably true for emacsclient connections.

Maybe my code should check current-idle-time; or maybe it should just
schedule something to run using run-with-idle-timer...

And I wonder if the gnus-demon-* functions that run should use
with-local-quit; at least, the ones that run external programs
or use network access should do this, I think.

They should, but there's really no overview of what needs to be
protected, so it's rather chancy.

All the backend functions should set a semaphore to say that they're in
use, though.

Yup.

If gnus-command-method is non-nil, then stuff is being run.  But is it
set globally, or just bound in that thread?  I'm not sure how the Emacs
threading model works...

I just tried it, and it worked for me:

21:31:40 229 SELECT "sent.2010w38"
21:31:40 230 CREATE "sent.2010w38"

[Replying to a random art on this thread]

My X server crashed today (the laptop, not the X process) and that
forced me to start up gnus again.

So I installed the current master to try it out.  That was commit
c833671c9d32c73eb7ff7d40e2f99bd9a570bc4e.

It was unable to login to my imap at all; The server buffer said
denied.

The relevant config from gnus-secondary-select-methods is:

 (nnimap "L"
	 (nnimap-address "localhost")
	 (nnimap-need-unselect-to-notice-new-mail nil)
	 (gnus-check-new-newsgroups t)
	 (nnimap-stream shell)
	 (imap-shell-program "/usr/sbin/myimapd -n")
	 (nnimap-authinfo-file "~/.iai.gpg"))

(with some of the names changed to protect both the innocent /and/ the
guilty. ☺)

I had to back down to commit 6e9a3072f961d1003cf14b37fdd4c922cc4e3db1
in order to interact with mail at all.

(Even though imapd is run via imap-shell-program, it is not pre-
authenticated.  I only use the shell because running imap over tcp —
even over loopback — has about twice the latency.  Using the pty
cuts the startup time in half.)

nnimap uses auth-sources now.  Perhaps the `auth-sources' variable
should be overridden by `nnimap-authinfo-file' if it exists?

The rest looks OK, and you should have been prompted for user
name/password.  That didn't happen?

If you still have access to the git version, could you look into the
"*nnimap ... *" buffer when this happens and post the contents?

OK.  When I tried having an ~/.authinfo.gpg file, I got a prompt from
gpg-agent every time I sent a mail, even though I have gnus post mail
to localhost:smtp, which does not require any auth.  So I went back
to just an .authinfo file.  (Nothing in it matters much, since it is

I will try it out again later, and do that if it still fails.

(The nice thing about git is that it is *easy* to change versions; only
the cost of gnus startup takes any time at all.)

This doesn't happen to me. However, my "send-mail-function" is set to

Ditto for the Usenet message I just sent: this is from imap-log:

07:02:12 1183 SELECT "misc-news"
07:02:12 1184 CREATE "misc-news"
07:02:12 1185 APPEND "misc-news" {1774}
07:02:12 1186 SELECT "misc-news"

But the message itself is not stored in this folder (which already
exists, so I am not sure why the CREATE is needed).

regarding previous reply: I just searched for 87aan9t5uz.fsf on the
Cyrus server, no results. So either it gets appended to a folder not on
the IMAP server. Or it says it is appended, but it actually is not. 

Re: More IMAP testing, please

[James Cloos]

[sending this vai gmane from another box...]

It turned out that the bug is that imap-shell-program override in
gnus-secondary-select-methods is ignoreed, defaulting to the version
specified in imap.el.

Startup might have improved.  the imapd side of things ony needed about
half as much time, since it did an lsub and examines, rahter than status,
examine tuples, followed by an lsub, followed by another round of status,
exmine tuples.  But now emacs is spinning.  Overall startup might end up
similar or even worse that before?

Fixing the imap-shell-program bug, though, it the biggest issue.

I am now having the same problem (no prompt for user/password nor even
to decrypt my .authinfo.gpg file) after doing a git pull about ten
minutes ago.  Unfortunately I'm at work so can't spend too much time
debugging and have switched back to a previously working snapshot for
the time being.

My select method setup (both my cyrus and exchange IMAP servers are
secondary) look similar to James' though I removed the reference to
nnimap-authinfo-file some time ago in favor of auth-sources.

One thing that looks odd is I've got several buffer names like this:

   "*nnimap mail.mywork.org nil  *nntpd**<2>" 0 Fundamental

Somehow having *nntpd* in what looks like a buffer intended for IMAP
seems wrong.

I take it back, my select methods are not really like James' at all in
retrospect.  In case it helps, here they are:

	    (nnimap "cyrus"
		    (nnimap-address
		     "mail.mywork.org")

It looks to me like there is a server variable nnimap-shell-program
and a global variable imap-shell-program which is used as the default
for the server variable.  And it certainly worked for me to set
imap-shell-program.

Yesterday, I switched to using server variables since I wanted a
different program for each server, and at one point Gnus started
trying to use some default ssl programs.  Restarting Gnus made it
use my value.  Not sure what caused this.

smtpmail.el needs to be smarter then.  I guess it currently looks for a
password regardless.  That seems to be an issue with
`smtpmail-try-auth-methods' and not with auth-source.el specifically so
I think it should be treated as a bug.

Ah! So the culprit is likely in my .gnus

Earlier this afternoon, I tried fiddling with it, but so far without the
desired result. I have a feeling I will discover something ugly in my
configuration.

If/when I find out, I'll post it here.

It'll work if you set imap-shell-program before loading nnimap.el, but
not the other way around.  That's the problem with these backwards
compatibility workarounds.

It's possible to do it dynamically in `nnimap-open-server', but you end
up now knowing whether to trust the value of nnimap-shell-program or
imap-shell-program, and somebody is going to be unhappy either way.

The nntpd buffer is the buffer used for communication between the
backend and Gnus, so it's correct, even though it's confusing.

In fact it did end up the same.  The only difference is that emacs' now
takes a quarter of the time itself, instead of nearly none.

So it is 2:1:1 imapd:emacs:imapd instead of 0:4 emacs:imapd.  (Rounded,
of course.)

I doubt there can be much improvement, unless the (new) middle step,
between the lsub+examine and the emamine+uidfetch, can be improved.

An ltrace on emacs during that point showed lots of mmap/memcpy/free
activity.  But no (or *very* few) syscalls.  Notably I never saw calls
to brk(2), so gc was probably the biggest issue.

I'm happy.  Other aspects seem faster.  And the improvement over tcp
will be significant, from the pipelining.  But startup time over a pty
is a wash.

They were empty, but I think I understand it.  In Message-id:

Are there ^M characters in this for you?

      (with-temp-buffer
        (insert-file-contents "~/.netrc")
        (buffer-string))  

because that's what netrc.el does.  The decoding and line conversion are
entirely handled by Emacs with all the settings defaulted.  The
`coding-system-for-read' variable, in particular, is not set.  Check
your `file-coding-system-alist' to be sure you don't have any overrides.
