Package: dovecot-core Version: 1:2.2.9-1 Severity: important Dear Maintainer,
We have a control panel which does a restart of dovecot after installation. The problem is that if we catch stderr output, our installer hangs. This problem occurs only in Jessie. This bug seem really similar to the one as described there: https://bugzilla.redhat.com/show_bug.cgi?id=730746 When we do not catch stderr output from the command which is responsible to restart dovecot, all goes fine. Piece of code from our installer to let you understand (written in perl): ### ... # /usr/sbin/service dovecot restart $rs = execute( "$main::imscpConfig{'SERVICE_MNGR'} $self->{'config'}->{'DOVECOT_SNAME'} restart", \$stdout, \stderr ); ... ### ### ... my $sel = IO::Select->new(); my $pid; if(defined $stdout && defined $stderr) { $pid = open3(gensym, \*CATCHOUT, \*CATCHERR, $command); $sel->add(\*CATCHOUT, \*CATCHERR); } elsif(defined $stdout) { $pid = open3(gensym, \*CATCHOUT, ">&STDERR", $command); $sel->add(\*CATCHOUT); } elsif(defined $stderr) { $pid = open3(gensym, ">&STDOUT", \*CATCHERR, $command); $sel->add(\*CATCHERR); } else { system($command); return getExitCode($?); } while (my @ready = $sel->can_read()) { foreach my $fh (@ready) { if ($stderr && fileno($fh) == fileno(\*CATCHERR)) { $$stderr .= do { local $/; <$fh> }; } elsif($stdout) { $$stdout .= do { local $/; <$fh> }; } $sel->remove($fh) if eof($fh); } } waitpid($pid, 0) if $pid; ... ### -- Package-specific info: dovecot configuration --------------------- # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.11-2-amd64 x86_64 Debian jessie/sid auth_mechanisms = plain login digest-md5 disable_plaintext_auth = no mail_location = maildir:~/ mail_plugins = quota namespace inbox { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir:User quota quota_rule = *:storage=1GB quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } } service quota-warning { executable = script /var/www/imscp/engine/quota/imscp-dovecot-quota.sh group = imscp unix_listener quota-warning { mode = 0600 user = vmail } } ssl = no userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { pop3_uidl_format = %u-%v } protocol lda { auth_socket_path = /var/run/dovecot/auth-master mail_plugins = quota postmaster_address = [email protected] } -- System Information: Debian Release: jessie/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.11-2-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages dovecot-core depends on: ii adduser 3.113+nmu3 ii debconf [debconf-2.0] 1.5.52 ii libbz2-1.0 1.0.6-5 ii libc6 2.17-97 ii libpam-runtime 1.1.3-9 ii libpam0g 1.1.3-9 ii libssl1.0.0 1.0.1f-1 ii libwrap0 7.6.q-24 ii openssl 1.0.1f-1 ii ucf 3.0027+nmu1 ii zlib1g 1:1.2.8.dfsg-1 dovecot-core recommends no packages.
