Description Alexander Veit 2012-08-26 13:25:27 UTC

After updating Postfix to 2.9.3 the commonly used database type hash does not work anymore.

emerge.log:
1345135439:  >>> emerge (9 of 27) mail-mta/postfix-2.9.3 to /
1345135440:  === (9 of 27) Cleaning (mail-mta/postfix-2.9.3::/usr/portage/mail-mta/postfix/postfix-2.9.3.ebuild)
1345135444:  === (9 of 27) Compiling/Merging (mail-mta/postfix-2.9.3::/usr/portage/mail-mta/postfix/postfix-2.9.3.ebuild)

1345136143:  >>> unmerge success: mail-mta/postfix-2.8.9


Reproducible: Always

Steps to Reproduce:
1. Use a Postfix configuration with
  alias_maps = hash:/etc/aliases
or
  transport_maps = hash:/etc/postfix/transport
or similar.

2. Update a working version < 2.9 with the above configuration to 2.9.3.

3. Watch the Postfixe log file for errors.
Actual Results:  
In the log appear error messages like

Aug 26 10:39:07 [postfix/trivial-rewrite] warning: hash:/etc/postfix/transport lookup error for "*"
Aug 26 10:39:07 [postfix/trivial-rewrite] warning: hash:/etc/postfix/transport is unavailable. unsupported dictionary type: hash

Expected Results:  
The update should not break the configuration.

Do not turn off berkdb USE flag is you have hash or btree lookups in your setup.  There is a big fat warning in the ebuild output.  You should read it.
