5. Upgrading Sympa

Sympa upgrade is a relatively riskless operations, 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).


5.1 Uncompatible changes

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). As mentionned at the beginning of this file, uncompatible changes are preceded by '*****'. While running the make install Sympa will detect the previously installed version and will prompt you with uncompatible changes between both versions of the software. You can interrupt the install process at that stage if you are too frightened. Output of the make install :

You are upgrading from Sympa 4.2
You should read CAREFULLY the changes listed below ; they might be uncompatible 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>


5.2 CPAN modules update

Required and optional perl modules (CPAN) installation is automatically handled at the make time. You are asked before each module is installed. For optional modules, associated features are listed.

Output of the make command :

Checking for REQUIRED modules:

5.3 Database structure update

Whatever RDBMS you are using (mysql, SQLite, Pg, 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 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 Mysql or if the DB user configured in sympa.conf does have sufficient privileges, then you should change the database structure yourself, as mentionned in the NEWS file.

Output of Sympa logs :

5.4 Preserving your customizations

Sympa comes with default configuration files (templates, scenarios,...) that will be installed in the /home/sympa/bin directory. If you need to customize some of them, you should copy the file first in a safe place, ie in the /home/sympa/etc directory. If you do so, the Sympa upgrade process will preserve your site customizations.


5.5 Running 2 Sympa versions on a single server

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 \
            --with-mandir=/home/sympa-dev/man \
            --with-initdir=/home/sympa-dev/init \
	    --with-piddir=/home/sympa-dev/pid
            --with-lockdir=/home/sympa-dev/lock \
            --with-sendmail_aliases=/home/sympa-dev/etc/sympa_aliases

You can also customize more parameters via the /home/sympa-dev/etc/sympa.conf file.

If you wish to share the same lists in both Sympa instances, then some parameters should have the same value : home, db_name, arc_path
