mailer.py bug fixes

From: <Servatius.Brandt_at_fujitsu-siemens.com>
Date: 2005-06-24 17:00:07 CEST


I found some bugs in tools/hook-scripts/mailer/mailer.py. A patch with
the fixes is included below. It is based on revision 14358 in the
1.2.x branch.

The docs in mailer.conf.example talks about "truncate_subject" (with
underline) but mailer.py looks for "truncate-subject" (with dash).
Since all other option values use an underline, I fixed this in
mailer.py for consistency.

generate_content() forgot to set "show_nonmatching_paths" in the "data"
it passes to the render() method of the TextCommitRenderer. I added it.

When the [maps] section specifies the same mapping specification to be
used by more than one option (e.g. reply_to = [mail-addresses] and
to_addr = [mail-addresses]), the script fails. I postponed the removal
of a map section name from the self._groups list in Config._prep_maps()
until all map specifications have been processed.

Mappings are only applied when the option value is a single word, e.g.
"to_addr = sally". When adding another recipient as in
"to_addr = sally harry", mappings are not applied. This is because
Config.get() passes the whole string "sally harry" to the mapper
function. I changed this to apply mappings wordwise.

The "exclude_paths" option is very helpful but not documented in
mailer.conf.example. I made only changes to mailer.py itself, so please
update the documentation.
