I think that the best way to create a complete calculated question will be to use the structure build when importing a calculated question using the xml import.
Unless you want to simulate the edit_calculated_form.php, the datasetdefinitions_form.php and the datasetitems_form.php.
The code you put on 1.9 seems to use this hypothesis but needs correction if you want to do it this way.
Can you give some instructions on how to use the generator.php i.e. where do you put the generator code?

Hi, I'm having problems using this script with 1.9.2.

From command line:

$ php generator.php -u admin -pw loadtest -P mdl_ -v -nc 100 -ns 500 -nq 50 -qq 20
Notice: Undefined index: no-data in /var/www/html/loadtest/moodle/generator.php on line 277
Generating 500 students...

Notice: Undefined variable: DB in /var/www/html/loadtest/moodle/generator.php on line 318

Fatal error: Call to a member function get_field_sql() on a non-object in /var/www/html/loadtest/moodle/generator.php on line 318

From web interface:

Any advice on how I can get this going? Thanks..

Yes, the trouble is that you are using the HEAD version of this script. You need to checkout the contrib branch with the MOODLE_19_STABLE tag. It should work fine then.

Thanks.

I found that ~80% of the this script's running time is spent in rebuild_course_cache().

I moved the rebuild_course_cache() outside of the two nested loops for section/module creation and it sped it up dramatically. It looks like it should be OK to do the cache rebuilding at the end of the module/section generation because the cache information doesn't look like it gets used inbetween (unless someone was trying to view the course while the generator was still creating it?). I've attached a patch if you would like to take a look (i'm using the MOODLE_19_STABLE version).

By the way, if I remember correctly, this tool so far still can not generate "quiz attempt" data. Am I correct on this? It would be really nice if this tool could also generate quiz attempt data for testing Quiz Performance issues (for larger classes with lots of quiz questions and lots of quiz attempts, e.g. > 100,000 attempts for one quiz)...thanks!
