Subject: dash breaks postfix

Date: Wed, 12 May 2010 13:17:37 +0200

Package: dash
Version: 0.5.5.1-4
Severity: critical
Justification: breaks unrelated software

I'm not sure and didn't investigate whether this is really dash that is at
fault or the postfix package but since upgrading dash postfix cannot be started
anymore. Downgrading dash fixed it.

Seems like broken IFS handling in read, postfix's post-install script
does:

test -n "$create" && {
    exec <$daemon_directory/postfix-files || exit 1
    while IFS=: read path type owner group mode flags junk
    do
        IFS="$BACKUP_IFS"
        set_permission=
        # Skip comments. Skip shared files, if updating a secondary instance.
[snip]
        # Skip hard links and symbolic links.
        case $type in
        [hl]) continue;;
        [df]) ;;
           *) echo unknown type $type for $path in $daemon_directory/postfix-files1>&2; exit 1;;
        esac
[...]

And apparently the whole colon-separated line from postfix-files ends up
in $path instead of being split in the various variables.

Cheers,
Julien

Subject: fails to start: bashism ?

Date: Thu, 13 May 2010 15:10:16 +0200

  Hi again,

  I use dash as /bin/sh, and downgrading dash to 0.5.5.1-3 does the
trick. The problematic line is

line 441 of /etc/postfix/post-install:
    while IFS=: read path type owner group mode flags junk

  With dash version 0.5.5.1-4, the variables are apparently not set correctly.

  I'm unsure whether it is a dash bug or a bashism (see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=581351 which I've
just noticed). Please merge bugs either ways depending on who's
faulty.

  Cheers,

      Vincent

Yes, thanks for the reports.  I confirm the bug, the regression is
introduced by the
debian/diff/0009-BUILTIN-Honor-tab-as-IFS-whitespace-when-splitting-fi.diff
patch added in 0.5.5.1-4.  Upcoming upload will fix it.

Regards, Gerrit.
