Changes to GroupServer¶
For new installations of GroupServer the most important change is the updated buildout recipes, that should make the process of installing GroupServer more robust. For existing systems DMARC support has been added, as well as improvements to how incoming SMTP is handled. Finally there have been many other minor code improvements.
Updated buildout recipes¶
GroupServer itself is installed using four recipes that are used by Buildout. All four recipes have been improved. There is now a base recipe class that is shared by the recipes, and unit-tests have been added to ensure the recipes work as expected. Specific improvements include the following.
- The recipe that creates the Postfix configuration has been updated, fixing a problem that Bill found.
- The recipe that crates the PostgreSQL tables now uses the setuptools package to extract the SQL files from the different modules. The modules are now passed into the recipe from Buildout, rather than being written in the recipe.
- The creation of the GroupServer site is now simpler, as only the site-administrator is created during installation. This solves many issues with the email-address of the normal group-member conflicting with the email address of the site administrator.
With the Slivovica release of GroupServer messages are more
likely to be received by people whose email is provided by hosts
that implement strict DMARC. With strict DMARC messages are
checked to ensure that message was actually sent from the host
listed in the
From address. All mailing-lists (including GNU
Mailman, Google Groups, and Yahoo! Groups) modify the message
before sending it out, and this would cause the DMARC check to
Like most other mailing lists, GroupServer now rewrites the
From address if the group member uses an email provider that
implements strict DMARC. The new address includes the name of the
sender, and the ID of his or her profile (see Feature
4108). This ensures that the person who sent the message can
still be identified, and email message will still get through.
With the Slivovica release of GroupServer email messages are
correctly sent to GroupServer when it is running on a
non-standard port. Messages are received by Postfix, which then
smtp2gs programme to add the message to
GroupServer. Previously manual intervention was needed if
GroupServer was listening to a non-standard port.
Now all components of GroupServer correctly handle the port that
is set in the configuration file when GroupServer is first
set-up. This includes the recipe that creates the alias file
for Postfix, the
smtp2gs script that uploads the email
message, and the
gs.form library that
smtp2gs uses to
connect to GroupServer.
Minor code improvements¶
Four components have undergone minor updates for Slivovica.
- Add member:
- Fixed an error with the dependencies of the product that added a member to a group.
- Site style:
- Some errors in the CSS have been fixed.
- The code that imports
mboxfiles has been updated, and it now uses the same core code as the
- Starting public groups:
- Public groups are now visible on the homepage of the site as soon as they are started, closing Bug 4105.
In addition the following general changes have been made to GroupServer.
- Three fundamental products — gs.core, gs.dmarc, and gs.form — have been published to PyPI.
- Sphinx is now used to generate the documentation for
- Unit tests have been added to many of the products that make up GroupServer. These tests make it more likely that these components that make up GroupServer will work correctly now and in the future.
- Where possible Python 3 support has been added to the products that make up GroupServer. The main change has been to switch to Unicode-text by default. While not all products have been updated, many have.
- Finally, more code now raises errors, rather than relying on
assertstatements. As these errors should never happen hopefully no-one will notice a difference.
To get Slivovica go to the Downloads page for GroupServer and follow the GroupServer Installation documentation. Those who already have a functioning installation can update an existing GroupServer system.
Update an Existing GroupServer System¶
To update a system running the Ouzo release of GroupServer (14.03) to Slivovica (14.06) carry out the following steps.
Download the Slivovica tar-ball from the GroupServer download page.
Uncompress the tar-ball:
$ tar cfz groupserver-14.06.tar.gz
Change to the directory that contains your existing GroupServer installation.
Copy the new version-configuration files to your existing GroupServer installation:
$ cp ../groupserver-14.06/[vz]*cfg .
In your existing GroupServer installation run:
$ ./bin/buildout -n
Restart your GroupServer instance.
