Installation
The installation of the module occurs about the extension Repository in back end of Contao.
A manual installation is possible. Download the ZIP file from Extension Repository, unzip and transfer it.
A directory should have been created "/system/modules/graphicalautomator".
Then call /contao/install.php - Perform Update Database.
( /typolight/install.php in older TYPOlight installations )
The Graphical Automator module is only useful when using the module "GraphicalText".
Introduction
The module Graphical Text generated graphic files that are stored in /system/html. Normally, e.g. in navigation, do not change the file name. Not so with a counter (e.g. visitor counter), when this can be graphically show will be produced continuously new graphics files. However, the old image files are not deleted again.
The Contao CRON clears once a day the /system/tmp directory, but not the /system/html directory. This is a good thing! No one wants that every day all the preview images and converted images must be recalculated.
The old pictures of the visitor counter (to stay with the example) but can safely be deleted.
Just that this module was written.
Beschreibung
Das Modul Graphical Automator klinkt sich dazu in den CRON von Contao ein, genauer in den "daily" Aufruf per Hook. Das Modul sucht dabei alle Dateien die den Präfix "graphtext-" haben.
Damit nicht genau zum Zeitpunkt der Lieferung neu generierter Grafiken diese gleich wieder gelöscht werden und somit ein Broken Picture im Browser erzeugt, wird der Zeitstempel der Dateien geprüft und nur solche gelöscht, die älter als 10 Minuten sind. Da zum selben Zeitpunkt die Seiten im Cache auch gelöscht wurden, genauer gesagt kurz vorher, braucht hier auf die Grafik Dateien von Seiten im Cache normalerweise keine Rücksicht genommen werden.
Im Backend unter System-Log taucht dann eine solche Meldung auf:
[08.04.2010 00:47] Purged 35 Graphtext images in thumbnail directory.
Feinheiten
Die Mindest-Haltezeit kann mittels Eintrag in der localconfig.php geändert werden.
Beispiel für 24 Stunden:
$GLOBALS['TL_CONFIG']['purgeHtmlFolderGToffset'] = 86400;
Weitere Beispiele sind in der mitgelieferten config.php enthalten.
