Bug 90479

I can't reproduce this with kmail from head and a uw imap server.
Can you provide an ethereal log from a sync of the disconnected account?

cat dimap.textdump

5 LIST "" "Mail"

* LIST (\NoSelect) "/" Mail
5 OK LIST completed

6 SELECT "Mail"

6 NO SELECT failed: Can't open Mail: not a selectable mailbox

7 LIST "" "Mail"

* LIST (\NoSelect) "/" Mail
7 OK LIST completed

I can provide a hexdump if required

I think the above clearly shows that cacheimap in kmail is trying to select my top level mail folder even though the server identified it as (\NoSelect).
This is against the imap RFC section 7.2.2. 
The above trace was made with kde cvs from only a few days ago.
regular imap in kmail works just fine with this account.

Can this bug be moved to "NEW", as I think this is now confirmed?

Here is more debug output, including the kio_imap debug output.

Would be interesting if you could enable kdDebug(7116) << "Writing: " << aStr << endl;
in IMAP4Protocol::parseWriteLine   (kdepim/kioslave/imap4/imap4.cc)

and kdDebug(7116) << result.cstr(); 
in imapParser::parseLoop (in imapparser.cc)

(then "make; make install" in kdepim/kioslave/imap4, and restart kmail)

With the requested debugging uncommented. And my password removed :-)

Can this now have its status changed from "UNCONFIRMED" to "NEW" as I think I've provide plenty evidence of the problem.
I'm no IMAP expert, but it appears kmail is trying to SELECT a name that the server has informed it is "\noselect"

> IMAP4::get -  imap://nicbrown edinburgh cisco com:143/Mail/;UID=0:0

OK, kio_imap returns message/directory when noselect is set and noinferiors is NOT set.
But it seems kmail ignores that.

It only has code for message/digest, which is returned when both noselect 
and noinferiors are set.

Ah, hmm, wait, this might be as simple as this fix:

Can you try it?
Thanks.

If this works, kmfolderimap.cpp:709 might need the same fix, for online imap.

> OK, kio_imap returns message/directory when noselect is set and noinferiors is NOT set. 

Are you sure?
In the code below it appear that it returns inode/directory if noselect is set and noinferior is not set.

I'll try your fix anyway and let you know.

imap4.cc:2056
<snip>
 if (!item.noSelect ())
      {
        atom.m_uds = UDS_MIME_TYPE;
        if (!item.noInferiors ())
        {
          atom.m_str = "message/directory";
        } else {
          atom.m_str = "message/digest";
        }
        atom.m_long = 0;
        entry.append (atom);
        mailboxName += '/';

        // explicitly set this as a directory for KFileDialog
        atom.m_uds = UDS_FILE_TYPE;
        atom.m_str = QString::null;
        atom.m_long = S_IFDIR;
        entry.append (atom);
      }
      else if (!item.noInferiors ())
      {
        atom.m_uds = UDS_MIME_TYPE;
        atom.m_str = "inode/directory";
        atom.m_long = 0;
        entry.append (atom);
        mailboxName += '/';

        // explicitly set this as a directory for KFileDialog

> In the code below it appear that it returns inode/directory if noselect is set and noinferior is not set.

You're right, the double-negation in the if() confused me [this isn't my code].

Then this is just a "NoContent" folder (from the kmail point of view). So kmail knows
it has no mail in it. However it needs to be listed (to find its children). So the bug would
be in kio_imap4, which should list a folder without selecting it first. Carsten? :)

I don't know where the "select" comes from as this is not needed (and not
used afaik) for a listing. This problem is not present in online imap so
this has to be kmail - dimap specific. BTW, I already tested this with a
UW imap and could not reproduce the error.

Hmm, the request is IMAP4::get -  imap://nicbrown edinburgh cisco com:143/Mail/;UID=0:0
Looking at cachedimapjob, this seems to be called from CachedImapJob::checkUidValidity.
But this isn't called for noContent folders... (kmfoldercachedimap.cpp:637)
Nick, can you check if that line calls checkUidValidity for the problematic folder?
Use e.g. 
  kdDebug() << location() << " calling checkUidValidity ##########" << endl;
to see which folder it's about - it's normal to call it for the other folders.

Another way is to enable the kdDebug in KMFolderCachedImap::newState
to see exactly which steps of the sync process happen.

Will do.
I'm a newbie when it comes to kmail and kde code, but I'll also run it under gdb and see if I can't find the bug myself, can you point me to a good place for an intial break point for sync/checkmail button press?

Personally I prefer to use kdDebug to print out what's happening, rather than using gdb.
If you do want to use gdb, the breakpoint for a cachedimap check would be KMFolderCachedImap::serverSyncInternal,
but then you have to understand more of the code (e.g. the fact that every operation is asynchronous,
so serverSyncInternal is called back after each operation finishes). Plus it will be hit for every folder...
(break on KMFolderCachedImap::serverSync itself to get to the right folder first, then).

It's imho much faster to just print out the state changes and see what's happening.

Here the debug log with both the suggest debugs added.

Well I know where the bug comes from, so the debugging part is done, but I could
use your help on the "how to fix it" part :)

The problem is that for any subfolder, kmfoldercachedimap knows it's "\noselect"
when listing that folder's parent. It will then setNoContent(), and will skip
mail-related operations on that folder.

But the problem here is that the *toplevel* folder is \noselect. So there's no
listing during which kmail can learn about that.

I guess we need a way to enquire for the toplevel folder's attributes before
processing it. How do you do it with online imap? Some kind of ::stat() ?

Did anyone figure out how out to get the toplevel folders attributes if its marked "\noselect"?
(I'm still trying to familiarize myself with the kmail code :-)

> Did anyone figure out how out to get the toplevel folders attributes if its marked "\noselect"?

Carsten and I seem to interpret differently this bug report.
Is it about the toplevel folder, the one which is named after the [d]IMAP account,
or is it about the folder (called "Mail") which is inside?

He lacks time to look into this issue apparently, and I lack knowledge about prefix usage,
so please bear with me so I can understand the issue.

In the following ascii art "*" denotes a toplevel folder, and "-" a child of that folder.

Is it like:
* My Account
  - Mail
  - Other folders (which are in fact /Mail/Foo I guess?)

(and the problem is when listing "Mail")

or like
* My Account (which has a path of "/Mail")
  - Other folders (/Mail/Foo)
?

IIRC you said it works with online imap. But do both online imap and dimap show the same
structure in the folder tree?

It is the top level folder "/Mail" which is the root of my
account. All my mail folders are within this toplevel folder. (It
folder actually maps to the fs as /home/nicbrown/Mail/)

Online imap works just fine, and shows the structure;

*My account ("/Mail" which is /home/nicbrown/Mail/)
- inbox (which is /var/spool/mail/nicbrown)
- Sent
- Deleted Messages
- Drafts
- Work
-- Unix
-- Cisco
- Personal
-- Linux ("/Mail/Personal/Linux" which is
/home/nicbrown/Mail/Personal/Linux)
-- Fun

I have no idea what the folder tree looks like for this account with
dimap is as it fails on the top level folder :-)

In the kmailrc prefix=/Mail/ when using both imap and dimap.

Interesting: I tested dimap with a UW imap and prefix and the prefixed folder 
was not selected so I got no error. So it's even server specific. Puh, I'll 
see what I can do.

Its been a while, but I just rebuilt KDE CVS head from today and this problem is still present.

So I still see this error even with Kmail 1.9 which uses names spaces.

Error while reading folder Work on the server: 
  Unable to open folder Mail/Work. The server replied: SELECT failed: 
  Can't open Mail/Work: not a selectable mailbox 

My uw imap server is 2004.357.

I have in my config;

<snip>
[Account 4]
0="#mh/","#mhinbox","~/Mail"
Folder=
Id=1762082881
Name=Test
Namespace:#mh/=/
Namespace:#mhinbox=
Namespace:~/Mail=/
Type=cachedimap
</snip>

I suspect that this may relate to the following mozilla imap bug;
https://bugzilla.mozilla.org/show_bug.cgi?id=166885

Close this? It's really old...
