Abandon PDF Storage of e-Exams

1 Requirements

The current implementation of PDF Storage of e-Exams leads to significant problems with server load and request times, this affects the learners as well as the test admins.

With the current concept, pdfs are generated at test finish, when a test is limited by time, in nearly all cases there are several simultanious finishs of several participants.

The manual scoring as well as the scoring adjustment triggers generation of pdfs on each save.

For the first, the maintainer wanta to abendon the archive aspect of this feature. Since the pdf export in the test's export tab relies on the archived pdfs, we will implement a generation of pdfs during the export. So an export in general can still be created, but there is no system side archive aspect left.

The maintainer would like to change this for the current trunk as well as the stabel release branches, since the bug tickets relating to the problems get more and more.

3 Discussion

JourFixe, ILIAS [jourfixe], Jan 18, 2016: We follow the maintainer's suggestion and abandon this feature with 5.2. Björn will check if removing the feature for 5.0 and 5.1 is feasable and secure.

Heyser, Björn [bheyser] 29. April 2016: I created pull requests for merging the remove of pdf archive generation:

• #181
• #182

The changes I made are not large and not complex, so I support merging into the stable branches.

JourFixe, ILIAS [jourfixe], May 09, 2016: We agree with Björn's suggestion and ask him to remove the feature for 5.1 and 5.0, too.

4 Implementation

Implemented for ILIAS 5.2.x.
