Bug #7745: Fix cache expiration when deleting a mailbox

http://git.horde.org/diff.php/imp/docs/CHANGES?rt=horde-git&r1=0041e0fdad86a56507ed10f8ed09d320f5c85653&r2=4547574f667d07fc6b8166f70bd03a46066e2619

After patching imp-cvs and imp-git, they both work as expected. This 
bug is fixed here.

Thanks a lot.

Appears to be a cache issue.  Do these fixes help?  Note: CVS fix is 
different from the Git fix 
(http://lists.horde.org/archives/commits/2009-March/000663.html).

Changes have been made in CVS for this ticket:

http://cvs.horde.org/diff.php/imp/docs/CHANGES?rt=horde&r1=1.699.2.384&r2=1.699.2.385&ty=u
http://cvs.horde.org/diff.php/imp/lib/IMAP/Tree.php?rt=horde&r1=1.25.2.68&r2=1.25.2.69&ty=u

I noticed as well that, before calling getPollList, INBOX.Sent-02-2009 
appears in arrays _parent:protected and _tree:protected (which is the 
expected behaviour I guess) but not in array _fulllist:protected.

patched like this :

+ Horde::logMessage(print_r($imaptree,true), __FILE__, __LINE__, 
PEAR_LOG_ERR);

$flist = $imaptree->getPollList(true, true);

+ Horde::logMessage(print_r($imaptree,true), __FILE__, __LINE__, 
PEAR_LOG_ERR);





Sent disappear in  _parent:protected but still there in 
_fulllist:protected before calling $flist = 
$imaptree->getPollList(true, true);

Sent reappear everywhere after calling getPollList.



See attached log file. Log file contains login and running maintenance.

In IMP_Search::createVINBOXFolder(), can you put print_r($imaptree) 
statements around getPollList(), i.e.:



/* Create Virtual INBOX with nav_poll list. Filter out any nav_poll

  * entries that don't exist. Sort the list also. */

print_r($imaptree);

$flist = $imaptree->getPollList(true, true);

print_r($imaptree);



And see if the sent folder is reappearing in $imaptree after this call.

I was so happy to see this working that I didn't re-read before posting.

If Virtual Inbox is off, no matter what Virtual Trash is set to 
(on/off),  this is fixed using both version of imp, old cvs and latest 
git.

I'm not clear on what you mean here.  Are you saying that if you turn 
Virtual Inbox off, this is fixed?

Yes! setting $_prefs['use_vinbox']['value'] to 0  and 
$_prefs['use_vinbox']['value'] to 0 (or 1) solves the problem on both 
imp-git and the old imp-cvs.

Do you see this if both virtual inbox and virtual trash are disabled?   
  You may want to debug IMP_Folder::_onDelete() because IMP_IMAP_Tree 
is manipulated by various functions called in there also.

I have Debian 3.1 with php 4.3.10

For the record, also not running PHP 4 (was seeing it with PHP 5.1).

I've just tried with dovecot 1.0-0.beta8.3.fc5 (not the latest I know) 
and I get the same behaviour :-(

I deleted the user's pref before testing :

mysql> delete from horde_prefs where pref_uid='ronan';

login into horde, logout, then

mysql> update horde_prefs set pref_value='1230048685' where 
pref_uid='ronan' and pref_name ='last_maintenance';





I've attached horde and imp-git config files. Can someone reproduce 
with those config files ?

php 5.2.6 and 5.2.5.

OS : Fedora

The people seeing this wouldn't happen to be running PHP 4, are they?

We use courier-imap. Is anyone having this problem using the same IMAP 
server ?

I've just tried with IMP git and I still get the same problem.

Michael, if this isn't enough to reproduce it, I'm not sure what we 
gain by the ticket remaining open.

I forgot to mention that after running IMP_Folder::rename, the Sent 
folder doesn't exist on the IMAP server. So, on the server, the Sent 
folder has been renamed as Sent-12-2008.

I've modified Folder.php and Tree.php :

I can't find out why folder INBOX.Sent is gone from the tree at the 
end of function IMP_Tree::rename (which is the expected behaviour) and 
is back at the end of function IMP_Folder::rename!

With the following imp's settings :

$conf['server']['cache_folders'] = false;

$conf['server']['cachejs'] = 'none';

$conf['server']['cachecss'] = 'none';

$conf['msgcache']['use_msgcache'] = false;

$conf['mlistcache']['use_mlistcache'] = false;



If $_prefs['subscribe']['value']  is set to  1, maintenance works perfectly.

If $_prefs['subscribe']['value']  is set to  0, I get 'The folder 
"sent-mail" already exists'.



Can someone reproduce this as well ?

People are still seeing this, but again - someone will have to debug 
for themselves since none of the devs can reproduce.  I don't have any 
specific pointers on how to debug either - you're just going to have 
to trace the code and related data structures (i.e. IMP_Tree) to see 
where the error resides.

New month, same problem :( I have about 200 mailboxes but only some of 
them doing this. I have no idea why. It started after upgrading to 
Horde 3.3 and IMP4.3

I do get this as well. As soon as I login I get :

-   The current folder(s) "Sent" will be renamed to "Sent-nov-2008".

-   All old linked attachments more than 6 months old will be deleted.



After selecting both options, and clicking on "perform maintenance", I 
get the following messages :

# Sent folder being renamed at the start of the month.

# Success The folder "Sent" was successfully renamed to "Sent-nov-2008".

# Warning The folder "Sent" already exists



The Sent folder is visible in the folder tree nav bar but doesn't 
exist on the server.



From the Folder Navigator screen, I select "Rebuild Folder Tree" and 
the 'Sent' folder disappear from the folder tree nav bar as expected.



I can reproduce the same bug doing this :

- rename "Sent-nov-2008" to "Sent" from IMP

- logout

- set pref "last_maintenance" to "1226660810".

- login + maintenance

->  # Warning The folder "Sent" already exists



we use latest cvs version and courier-imap-4.3.0 and imp pref 'subscribe' = 0



I don't mind debugging but I don't know where to start. Any ideas?

I can't reproduce.  It most likely has something to do with the fact 
that the old mailbox is not being removed from the IMP_Tree object 
correctly (since exists() uses that object to check for existence), 
but I can't reproduce this so someone who sees this will have to debug.

I have maintenance enabled to rename the sent-mail folder at the beginning

of the month, but it will display after maintenance



- sent-mail folder being renamed at the start of the month.

- The folder "sent-mail" was successfully renamed to "sent-mail-11-2008".

- The folder "sent-mail" already exists



in the left menu "sent-mail" really exists but after sending new email 
it says Message sent successfully, but not saved to sent-mail. When I 
reload page sent-mail folder disappear then I must logout and login to 
Horde and send new mail, the sent-mail will then create again and 
works correctly.
