SQL error when creating a field.

#2694839: Unable to add 'field_quiz' in content type beacuse of index length issue with MySQL

Since the fix is a few weeks old and the module is basically unusable as is, I'd suggest a new release. :)

Apologies, I got turned around while browsing the git repo and thought it'd been fixed since then. The patch from the issue linked above is actually what broke it in the first place.

So I'm not sure if the field schema API has changed between 7.26 and the latest stable core? If so, then maybe a version requirement or some version-checking logic in hook_field_schema would be the way to go.

Update: It looks like this API was added in Drupal 7.37. If you rely on it, I'd recommend adding dependencies[] = system (>=7.37) to the info file to avoid mystery errors.

(Or alternatively checking the core version in hook_field_schema(), but that's more code.)

Hi, iirc this is specifically an issue in 7.36 and older. I'd recommend simply adding a version dependency to the info file to make sure the module is not installable if the core is too outdated. Better to know explicitly why it doesn't work than having to hunt down the problem.

(There are some outdated production sites around that only apply the security patches. I don't like it either, but in that case I had to work with what I got. ;) )
