Hi, I'm running version 1.2.15 (so no doveadm) You could build Dovecot v2.0 and only use doveadm binary from it.
Does it just issue the command via IMAP? No direct filesystem operations?
It's all direct filesystem operations, no IMAP. But v1.2.15 can read v2.0's index files just fine.
Looks about ok. The main thing I'm worried is what happens if user creates mailboxes containing " or ' or ` characters.
Yeah, that was mostly me being lazy in my wanting to deal with escaping, so I just ignored them.
In what I originally wrote, I think it just won't touch them.
Or is the issue that the find command might remove them and then the indexes don't get fixed up? I suppose I could just make sure that the find ignores those dirs, but I thought (from other maillist reading) that the next time their client SELECTs the folder it'll fix it up anyways.
I was more thinking what happens if the user creates a mailbox called
rm -rf /or something.. Also if there are " or \ characters I think the LIST output will use literals and your parsing will break more or less badly.
That's certainly true. I guess I was just hoping to skip over those mailboxes with unpleasant characters for the moment :}
More likely I'll rewrite this more carefully in Perl.
I suppose another spin on this would be for me to script the preauth imap client to figure out which mailboxes have messages marked for deletion of such and such an age and then try to use EXPUNGE to wipe just them out. I'm not sure off hand if that's possible.
That would be a bit difficult at least to do via IMAP..
So I'm finding. I guess I was thinking I could find the messages in a SELECTed mailbox via some parsing of either
- UID SEARCH DELETED X-SINCE $N_days_ago (where X-SINCE search X-SAVEDATE instead of INTERNALDATE), or
- UID FETCH 1:* (INTERNALDATE X-SAVEDATE FLAGS) as I've seen bantered about, or
- combine the two and SEARCH DELETED, then UID FETCH $initial_uid_list (X-SAVEDATE FLAGS) to refine the list.
Then use the (U?)IDs I get back from that to do
- UID EXPUNGE $uid_list
Of course I've only started researching that avenue, so maybe that's not so reasonable.
I'm starting to see why so much effort has been expended on this front.
Thanks, Brian
