A version bump rewrites website views without announcing any of it, so "the
site looks wrong" after a migration is currently unanswerable.
snapshot_cow_views.py records every website_id view (key, mode, inherit_id,
active, arch and its md5) and diffs two snapshots. Rows come back as JSON
straight from Postgres because an arch holds newlines and pipes; the column
list is intersected with information_schema, since ir_ui_view does not expose
the same columns from 12.0 to 18.0. Snapshots hold customer template content,
so they go under private/ and stay out of git.
todo_upgrade.py takes one before and one after each OpenUpgrade run, then
prints the diff. Both are non-blocking: forensic material must never stop an
upgrade.
Measured on the real 12.0 -> 13.0 jump, the diff shows what no log reported:
71 -> 68 copies, 16 deleted and 13 created. portal.frontend_layout is not
converted but DELETED (id 2670) and RECREATED (id 3397), with its children
re-parented from one to the other. The four theme_technolibre copies,
muk_web_branding, project_agile and erplibre_website_snippets_basic_html are
dropped outright, and website_crm.contactus_thanks is renamed to
website_form.contactus_thanks.
