Hello,
I have a infrastructure using director in front of backend servers. So I normally run doveadm commands in director servers, not the backends. The problem I have is when I try to concatenate commands like this:
doveadm search -S /var/run/dovecot/auth-userdb -u ${user} SAVEDSINCE 5w | while read guid uid; do doveadm fetch -S /var/run/dovecot/auth-userdb -u ${user} size.physical mailbox-guid $guid uid $uid; done
The problem is that although when I run doveadm search command in the backend server I correctly get the list of mails, each line with the mailbox-guid and the uid of the message, when I run the same command in the director server, format of the list is corrupted and there are lines that contains just the mailbox-guid and the next the uid (of the previous) and the mailbox-guid of next, and so on. Like:
e62e0d3834ed094e5c7900007efb8a67 66 e62e0d3834ed094e5c7900007efb8a67 71 e62e0d3834ed094e5c7900007efb8a67 74 e62e0d3834ed094e5c7900007efb8a67 75 e62e0d3834ed094e5c7900007efb8a67 77 e62e0d3834ed094e5c7900007efb8a67 78 e62e0d3834ed094e5c7900007efb8a67
so I can't postprocess correctly the output. I think it could be a bug in the communication between the doveadm client and server.
PS: As the time of writing this email, I have realized that I could use fetch command directly. But, anyway, I want to report the problem/bug so it can be fixed.
