This is an old revision of the document!

Please take note that this work is still ongoing. The documentation should grow in a near future. ;-)


In this chapter, we will provide extensive information on what Sympa looks like “under the hood”. We hope this documentation will be particularly helpful to developers.

This chapter describes these modules (or a part of them):

This section presents all the files used in the Sympa engine. The files described are those contained in the sources, consequently:

  1. you will not find the files generated at compilation time,
  2. the files are not located in the same directory as you will find them in the compiled application.

Failing a better alternative, we present them as they appear in the src directory from the source distribution.

''./'' : Sympas sources root directory

These scripts are run at installation time. They perform the operations necessary to the correct install and runtime of Sympa.

  • : This script checks installed and required Perl modules. It also does the required installations.
  • : This script prints important changes in Sympa since last install. It is based on the NEWS ***** entries.
  • : This script sets symbolic links at installation time.
  • : This script replaces --VAR-- occurences at installation time.









Work in progress. All the tables are described already though.

This chapter describes the Sympa database.

The Sympa database contains 5 tables which are :

  • admin_table, this table stores a cache version of the moderators and owners of lists,
  • user_table, this tables registers the users as individual people,
  • subscriber_table, this table registers subscribers; it stores couples “(user, list)”, thus producing one entry by subscription for each user.
  • logs_table: this tables stores the Sympa logs,
  • netidmap_table, this table stores informations relative to authentification.

We provide here, for each table, a data dictionary and a fields' description.


This table is just a cache of the informations found in sympa.conf, robot.conf and lists' config files. It is used to speed up the access to informations regarding administrators. The sources of these informations are the configuration files and not this table.
