This feature must allow Sympa users to store archives in a different place that the classical web archives based on MHonArc.
The development was requested and paid by Bendlin GmbH.
The provided custom archiver stores the messages in a database. As long as a perl DBD exists for the chosen RDBMS, there should be no problem to transfer data from Sympa to this RDBMS.
|Field name||Data type||Field description|
|message_key||int(11)||an autoincremental numerical key|
|message_id||varchar(150)||the SMTP message identifier|
|group_id||varchar(150)||the name of the mailing list to which the message was sent|
|timestamp||int(11)||the epoch date when the message was sent|
|subject||varchar(300)||the content of the SMTP Subject field in the orginal message|
|message||text||the full SMTP message, including all the headers|
|uid||varchar(150)||a header X-UID from the message|
A parameter in sympa.conf activates / desactivates this feature :
We add a test to archived.pl. When archiving a message, if the
custom_archiver parameter is set to
on, an external script is called – instead of the code using MHonArc – that will store the message into the chosen database.
A few details about this script:
<sympa_home>/bin/etc/scripts/directory under the name
archiver_paththat replaces the existing
mhonarcparameter. This parameter can be defined at the list or virtual level. You can use any script name or path for the script. You can have as much versions of the script as you want. One for each list if you like.
You can download the script as a tar file which is version 5.4.6ca or a patch that can be applied in versions 5.4
This modification is allready in Sympa 6.0
You can use this version just now. As long as you don't modify wwsympa.conf, it won't change Sympa's behaviour. You will introduce the new archiver engine by changing custom_archiver parameter in wwsympa.conf.
CAUTION: Note that Sympa always guess that the custom archiver script accepts two variables : ”–list” whose value is the full name of the list (including the domain part) and ”–file” that will contain the absolute path to the message file that will be archived. Each time the custom archiver is called, it is called with these two parameters with their values filled.
To use our sample custom archiver, you need to:
In archived.pl, the parameters related to the database are:
host name: 'localhost' database type: 'mysql'; database name: 'custom_archive'; table in which data are stored: 'archive'; user name: 'toto'; password: 'tutu';
Either you use this values to test or you change them in custom_archiver.pl.
