There were already one just added upgrade.txt file so this ended
conflicting. Reviewed the contents, I've deleted the less detailed
note about pluginname, leaving the longer description added by Tim.
Ciao :-)
This applies to:
1. Upgrade from 1.9,
2. Import of questions exported from 1.9, and
3. Restore of courses backed-up from 1.9.
It also applies to the calculated question type.
The new logic is that the questiontext defaults to HTML if the format is
not specified, then all other fields default to the same format of the
question text.
However, good practice is that the XML file should specify the format
for each bit of text content.
This code is not 100% backwards-compatible, since some methods have new
arguments, however for question types that have not been updated, it
will just generate a PHP Warning, which is, I think, and OK way to let
qtype developers know that they need to update their question types.
This commit also includes a lot of useful tidying up of some of the unit
test helper code. I turned out that I could not use all the helper code
in my new tests, but despite that it will be useful in the future, so I
am committing it here.
Editing of some qtypes was broken since a previous commit by me earlier in the week.
Import of XML and GIFT should now work, but could use some more testing.
The solution is to not tidy the XML. The XML generated is already quite well laid out, and if we want it better, we should fix that, rather than trying to load the whole file into memory to reformat it.
Also, while investigating this, I found that we were not handling the mime-type of the exported file very elegantly, so I added a new mime_type method (defaults to getting the mime type of the file extension).
