The interface choice offered two ways to ACT on a migration and none to just
look at one. Entry [3] reads the progression file and the traces left under
private/, writes nothing, and can be opened as often as one likes — [0] there
returns to the interface choice, and a new [0] Cancel leaves the tool entirely
instead of forcing a migration to be started.
« stats » is deliberately not storable as a default: it does nothing, so
landing on it every time would only be in the way.
The dashboard answers what was asked — which modules were removed, and how far
between Odoo versions — plus what the recorded data already knew and nobody
was showing:
· elapsed time since the migration started
· module count per version, with the delta per bump — a jump losing 15
modules does not mean the same thing as one losing none
· modules reported missing or duplicated
· which fix hooks exist and which have run
· COW snapshots taken, with their view count over time
· how many commands ran, and the annotated decisions among them
Then, on demand: the removed modules with their justification, the same list
comma-separated to paste, a diff between any two COW snapshots (through the
existing snapshot_cow_views.py --diff), the decisions, and the last commands.
Computation lives in migration_stats.py as pure functions fed by
resume_context() — the same context the resume screen and its TUI already
render, so the step and version-bump state can never be described two
different ways. read_uninstall is INJECTED rather than reimplemented: it
resolves private-then-global itself, so the screen shows exactly the list that
would be applied.
Verified on a realistic progression: 1 j 03 h elapsed, 312 -> 297 -> 282
modules (-15 each), 5 removals across two bumps with their reasons, 4 COW
snapshots ordered by time, the fix applied for 14.0 and pending for 15.0, and
the progression dict byte-identical afterwards. The menu was checked to map
'' /1/2/3/0/9 to tui/tui/cli/stats/None/tui, and [0] to leave without asking
anything else.
