Sympa upgrade is a relatively riskless operation, mainly because the install process preserves your customizations (templates, configuration, authorization scenarios, ...) and also because Sympa automates a few things (DB update, CPAN modules installation).
Upgrading Sympa means that you follow these steps:
./configure OPTIONS..; make ; make install
And that' it! This command will perform all the required DB changes (if running MySQL, PostgreSQL or SQLite) and will update the configuration files if required.
New features, changes and bug fixes are summarized in the
NEWS file, part of the tar.gz (the
Changelog file is a complete log file of CVS changes).
For example, note that, starting from Sympa 6.2b.1, the minimum version for MySQL is 4.1.1, and for SQLite is 3.x.
Sympa is a long-term project, so some major changes may need some extra work. The following list consists of well known changes that require some attention:
wwsympa.confwas obsoleted, and default location of
sympa.confwas moved to
auth.conf(no default anymore so you may have the create this file);
user_data_sourceas a new value include2 which is the recommended value for any list.
NEWS lists all changes and of course, all changes that may require some attention from the installer. As mentioned at the beginning of this file, incompatible changes are preceded by '*****'. While running the
make install Sympa will detect the previously installed version and will prompt you with incompatible changes between both versions of the software. You can interrupt the install process at that stage if you are too frightened. Output of the
You are upgrading from Sympa 4.2 You should read CAREFULLY the changes listed below; they might be incompatible changes: <RETURN> ***** require new perlmodule XML-LibXML ***** You should update your DB structure (automatically performed by Sympa with MySQL), adding the following table (MySQL example): ***** CREATE TABLE admin_table ( ***** list_admin varchar(50) NOT NULL, ***** user_admin varchar(100) NOT NULL, ***** role_admin enum('listmaster','owner','editor') NOT NULL, ***** date_admin datetime NOT NULL, ***** update_admin datetime, ***** reception_admin varchar(20), ***** comment_admin varchar(150), ***** subscribed_admin enum('0','1'), ***** included_admin enum('0','1'), ***** include_sources_admin varchar(50), ***** info_admin varchar(150), ***** profile_admin enum('privileged','normal'), ***** PRIMARY KEY (list_admin, user_admin,role_admin), ***** INDEX (list_admin, user_admin,role_admin) ***** ); ***** Extend the generic_sso feature; Sympa is now able to retrieve the user email address in a LDAP directory <RETURN>
sympa_wizard.pl –check, the installation of required and optional Perl modules (CPAN) is handled. You are asked before each module is installed. For optional modules, associated features are listed.

Whatever RDBMS you are using (MySQL, SQLite, PostgrSQL, Sybase or Oracle), Sympa will check every database tables and fields. If one is missing,
sympa.pl will not start. If you are using MySQL, SQLite or POstgreSQL, Sympa will also check field types and will try to change them (or create them) automatically, assuming that the DB user configured has sufficient privileges. If you are not using those RDBMS or if the DB user configured in
sympa.conf does have sufficient privileges, then you should change the database structure by yourself, as mentioned in the
NEWS file (database structure is describe in the src/bin/ directory of distribution).

You might need, for some reason, to make Sympa run the migration procedure from version X to version Y. This procedure is run automatically by
sympa.pl -upgrade when it detects that
/data_structure.version is older than the current version, but you can also run trigger this procedure yourself:
sympa.pl --upgrade --from=4.1 --to=5.2
Sympa comes with default configuration files (templates, scenarios,...) that will be installed in the
/home/sympa/default directory. If you need to customize some of them, you should copy the file first in a safe place, i.e. in the
/home/sympa/etc directory. If you do so, the Sympa upgrade process will preserve your site customizations.
This can be very convenient to have a stable version of Sympa and a fresh version for test purpose, both running on the same server.
Both Sympa instances must be completely partitioned, unless you want the make production mailing lists visible through the test service.
The biggest part of the partitioning is achieved while running the
./configure. Here is a sample call to
./configure on the test server side:
./configure --prefix=/home/sympa-dev \ --with-confdir=/home/sympa-dev/etc \ --mandir=/home/sympa-dev/man \ --with-initdir=/home/sympa-dev/init \ --with-piddir=/home/sympa-dev/pid --with-lockdir=/home/sympa-dev/lock \ --with-aliases_file=/home/sympa-dev/etc/sympa_aliases
You can also customize more parameters via the
If you wish to share the same lists in both Sympa instances, then some parameters should have the same value :
If you're upgrading and moving to another server at the same time, we recommend you first to stop the operational service, move your data and then upgrade Sympa on the new server. This will guarantee that Sympa upgrade procedures have been applied on the data.
The migration process requires that you move the following data from the old server to the new one:
mysqldand copy the
/var/lib/mysql/sympa/directory to the new server;
/home/sympa/list_datadirectory that contains list config;
/etc/sympa/sympa.conf, and the file
wwsympa.confif it exists. Sympa new installation creates a file
/etc/sympa/sympa.conf(see sympa.conf parameters) and randomly initializes the cookie parameter. Changing this parameter will break all passwords. When upgrading Sympa on a new server, take care that you start with the same value of this parameter, otherwise you might have problems!
/home/sympa/etcthat contains customized scenarios, templates etc.
In some cases, you may want to install the new version and run it for a few days before switching the existing service to the new Sympa server. In this case, perform a new installation with an empty database and play with it. When you decide to move the existing service to the new server:
/data_structure.versionon the new server; change the version value to reflect the old number;
