dovecot - Jun 2007 - No auto-conversion of .customflags?

Hello,

I'm in the process of migrating 0.99 dovecot maildir boxes to a pair
of new machine. These servers were running the stable (etch) 1.0rc15
package of dovecot until yesterday and existing .customflags files
were correctly converted to dovecot-keywords. Yesterday I upgraded 
to the (finally, thanks to who did this) 1.0.0 etch backports package
and since then freshly migrated boxes get this error:
---
Jun 12 09:48:06 mb11 dovecot: IMAP(username):
stat(/longandboringpath/username/.customflags/cur) failed: Not a directory
---

Firstly, I thought Linux was one of the OS' that had a free dir stat, but
I guess I could have just hallucinated that.

But more importantly, obviously .customflags does NOT get converted
anymore and thus shows up in IMAP LIST commands.

Since I doubt that the backport people did change anything in the code
I suppose that this is a genuine 1.0.0 problem which probably should be
addressed for the upcoming 1.0.1 release.

Regards,

Christian

Actually that could happen simply if the LIST command was done before
any messages with keywords were tried to be accessed. I hadn't really
thought about this before. Anyway, for now you can fix this by setting:

maildir_stat_dirs = yes

After there are no .customflags files left, you can remove that.

Alternatively you can just rename all existing .customflags to
dovecot-keywords files. That's how Dovecot internally "converts"
them
also.

Since this could take months if not years with some of our "zombie"
mailboxes I guess I'll not take that route. ;)
Most of them are "empty" aka "0000" from pop3 only accounts 
anyway, happily created by the 0.99 dovecot.

Ah, that sounds like a plan. And seeing that 1.0 does not create an
empty default dovecot-keywords file when accessed by pop3, I presume
I could just get rid of these (the "0000" ones) altogether, right?

Looking forward to 1.0.1 anyways, as I'm getting bitten by the 
"UID larger than next_uid" bug here. ^_^
