ILIAS Folder Download – Wait dialog

1 Requirements

Until ILIAS 5.0.x we were using the plug-in «ILIAS Folder Download». Now we'd like to have its features in ILIAS itself.

The plug-in showed a wait dialog if a folder is being downloaded and informs the user that his download is getting prepared. It tracks the download.

Features:

• The user gets informed that something is happening.
• The user may cancel the download preparations anytime. This also ends the background process on the server side and the server resources are released immediately.
• A download limit can be set to disallow downloads of too big folders.
• The downloads are tracked in the database.
• PHP background processes work on Linux and Windows.
• Huge downloads should be background processes.

3 Discussion

JourFixe, ILIAS [jourfixe], Dec 07, 2015: We appreciate the feature request and schedule it for 5.2

• To support the use with load balancers the process should use SOAP (as this allows to address one machine).
• The feature can be activated in the Administration settings.
• We need a cron job to clean the tmp directory (which will increase through this process).
• Only one download is allowed per user. If a user tries to start a second download process, ILIAS has to ask if the first process shall be killed or continued (instead of a new second download). Please use Interruptive Modal as GUI element.

, 24 Aug 2016: This feature has been implemented as described above.
