That fixes it for me.

I use dovecot/php5 also and see nothing.  But I am also using dovecot 
1.0 (beta I think) - which provides namespace support and fixes some 
issues with flag updating when using an imap proxy among other things. 
  But I digress...



Crap... looking through the code I may have found the problem.  Does 
this commit fix this?

The bug report is not an exact fit, but it's the only google result 
for "php imap_fetchstructure dovecot"



fwiw, I am getting runaway apache processes that use 100% CPU, which 
is described in the bug report.  Memory usage is fine, though.



I spent a number of hours last night trying to figure this thing out, 
and that's all I could find.  (The rest of the time was trying to 
figure out how to get dovecot 0.99.14+ installed without reinstalling 
the whole system...stupid rpm-hell)

None of the issues in that bug report is what I am experiencing.

I'm using php-4.3.11-1.fc2.4.legacy with dovecot-0.99.13-4.FC2

http://72.14.203.104/search?q=cache:W4kNX-jxUGwJ:contribs.org/modules/mantis/bug_view_advanced_page.php%3Fbug_id%3D0000196+php+imap_fetchstructure+dovecot+problems&hl=en&gl=us&ct=clnk&cd=1&lr=lang_en&client=firefox-a

I see this with both PHP4 and 5. Just remove the @ from 
imap_fetchstructure() in line 246 of MailboxCache.php, disable mailbox 
caching, and go to your inbox. The mailbox is displayed fine, but you 
get a warning for every message.

I don't see it, and I'm using Dovecot. :/



Is everyone seeing the problem using PHP 4? Michael, I know you use 
Dovecot as well, right? Are you on PHP 5? (for the record I'm using 5).

This *is* a bug in IMP, as this obviously happens to everyone using 
Dovecot at the moment, I see similar issues here too, when using 
Dovecot. And this didn't happen in the past. Maybe we simply trigger a 
bug in Dovecot now, but still, it used to work.

:(

Ok, now I'm at a loss...



I've tracked this problem to IMP_MailboxCache::retrieve() line 246.   
For some reason imap_fetchstructure returns false, instead of the 
expected object.  At that point the pertinent variables are set to the 
following values:



$mailbox: Junk E-mail



$msgids:

array(1) {

   [0]=>

   string(4) "1577"

}



$mask: 16



$_SESSION['imp']['stream']:

resource(50) of type (imap)



$val: 1577



and imap_fetchstructure gives the following warning, and returns bool(false):



Warning: imap_fetchstructure(): No body information available in 
/home/ben/public_html/horde/HEAD/imp/lib/IMAP/MailboxCache.php on line 
253



What really gets me is that when viewing the message, the same 
function call with the same values returns the expected object...



I'm pretty sure this is not a problem with imp/horde at this point, 
and will close the ticket.  But, does anybody have any ideas what 
might be going on?



Oh, and fwiw, when viewing the mailbox listing, I get a bunch of those 
same warnings from imap_fetchstructure (one for each message)

I just did a bit more troubleshooting:



Same horde installation, pointed at two different IMAP servers.  Works 
fine with courier, doesn't work with dovecot.



I'll keep digging.

I can't reproduce this either.

Can't reproduce.  Since your index/mailbox values appear to be 
correct, this could only happen because IMAP_MailboxCache::retrieve() 
is not returning the correct information.  If using mailbox caching, 
try deleting the cache data.



I've implemented better error handling for this error in compose.php, 
but obviously that is not the entire solution to this issue.

Oh, yeah, I forgot to mention, that I get the same behavior from any 
folder, and from any message.

I just updated to the latest HEAD today, and I cannot reply, 
reply-to-list, reply-all, forward, or redirect to any messages.  All I 
get is a blank compose window.  My last checkout was mid-day on Jan 
18, and all was well then.
