Error after db upgrade about jal HOT 4 CLOSED

I've removed quik_html_old.py and it helped

from jal.

The problem is not related with DB upgrade itself.
Module quik_html_old.py was deprecated and not updated for some time already. It finally became incompatible with recent code changes and I removed it completely.
It appears that the file was kept on your disk as you unpacked new jal version on top of the previous one. I.e. new files were added, updated files were overwritten but outdated files were not deleted. So you got an error as quik_html_old.py isn't compatible with other code.
You corrected the problem in a right way. But I have no idea how to prevent it from happening... If you have a proposal - I'm ready to listen. If not, I think I'll close this issue as no fault.

Thank you for prompt reply. May be you can define strict list of importers, so that new version wouldn't try to use the old ones.

The are no limitation done intentionally - jal will try to load every "plugin" from import directory. It allows someone to create his/her own module for a specific import and don't share it publicly.
But anyway, your experience helped to re-think it and I understood that current implementation assumes that all modules are syntactically correct there. I'll try to make better error handling and simply ignore modules that raise exceptions during startup process.
