Implement transparent repository upgrade
ArneBachmann opened this issue · comments
Would avoid the manual migration hints in the README.md.
Either use the version information in the repository to determine format, or introduce a new repo_format counter starting from 0.
Alternatively, trigger this via sos upgrade to avoid silent repository changes.
Metadata update done automatically (as there's a backup file created anyway).
Revision data upgrade only after user confirmation (needs dump/backup or user confirmation).
This issue helps in implementing further evolutionary incompatible changes easier.
