# Roadmap
|
||
|
|
|
||
|
|
Milestones from the implementation plan. See SPECS.md for the architecture and the
|
||
|
|
sync semantics these items implement.
|
||
|
|
|
||
|
|
## M0 — skeleton (done)
|
||
|
|
|
||
|
|
- [x] Initialise jj colocated with git; `.gitignore` written before the first build
|
||
|
|
- [x] `devbox.json` pinning Rust 1.97.1, pimsync 0.5.11, jujutsu 0.44.0, radicale 3.7.8
|
||
|
|
- [x] Configuration model with referential validation, reporting every problem in one pass
|
||
|
|
- [x] `calcalist doctor` — pimsync presence and version series, state directory, configuration
|
||
|
|
- [x] Define the full CLI surface; unimplemented commands exit 2 rather than pretend
|
||
|
|
- [x] SPECS.md: Rust naming conventions, `devbox run check` gate, recorded sync semantics
|
||
|
|
|
||
|
|
## M1 — bidirectional sync
|
||
|
|
|
||
|
|
Core modules:
|
||
|
|
|
||
|
|
- [ ] `state.rs` — JSON sidecar, atomic temp + fsync + rename; records each aggregate's
|
||
|
|
resolved target endpoint id **and** backend type
|
||
|
|
- [ ] `vdir.rs` — read and write vdir directories
|
||
|
|
- [ ] `ical.rs` — surgical line-level `.ics` editing (UID rewrite, property injection),
|
||
|
|
respecting RFC 5545 folding; no parse-and-reserialize
|
||
|
|
- [ ] `provenance.rs` — deterministic `blake3(aggregate_id, source_id, source_uid)` UIDs
|
||
|
|
- [ ] `reconcile.rs` — the aggregation engine; pure, no I/O
|
||
|
|
- [ ] `pimsync.rs` — generate `pimsync.conf` (with `on_empty skip` and `on_delete skip`),
|
||
|
|
drive one-shot `pimsync sync`
|
||
|
|
- [ ] `google/auth.rs`, `google/api.rs`, `google/convert.rs`
|
||
|
|
- [ ] Reintroduce `SchedulingSuppression` in `config.rs` (removed in M0 as dead code)
|
||
|
|
|
||
|
|
Safety-critical behaviour:
|
||
|
|
|
||
|
|
- [ ] **`events.import` gate — do this first.** Import an attendee-bearing event whose
|
||
|
|
guests are on a mail sink we control and confirm no mail is emitted; repeat for
|
||
|
|
update and delete under `sendUpdates=none`. The Google attendee path depends on
|
||
|
|
it. Fallback if it fails: the same demotion transform used for CalDAV.
|
||
|
|
- [ ] `sync` refuses to run on aggregate target drift, before reconciliation
|
||
|
|
- [ ] `aggregate retarget` — flush unrouted creations against the old target, then
|
||
|
|
re-materialise; keep old orphans by default
|
||
|
|
- [ ] Mass-deletion guard (`max_delete_fraction`), overridable with `--force`
|
||
|
|
- [ ] Echo suppression: derived UIDs are never re-ingested as source events
|
||
|
|
|
||
|
|
Tests:
|
||
|
|
|
||
|
|
- [ ] `reconcile` table-driven cases: create/update/delete each direction, both-sides-changed,
|
||
|
|
routing, echo suppression, mass-delete abort
|
||
|
|
- [ ] `ical` round-trip fixtures: recurring with overrides, all-day, TZID, unknown `X-` props
|
||
|
|
- [ ] Integration against Radicale plus a `file://` WebCal fixture; assert idempotence
|
||
|
|
- [ ] Safety: no live `ATTENDEE`/`ORGANIZER` on a CalDAV-targeted mirror, `VALARM` intact,
|
||
|
|
`PARTSTAT: DECLINED` maps to `TRANSP: TRANSPARENT`, emptying a source aborts
|
||
|
|
- [ ] Retarget: drift makes `sync` exit non-zero having written nothing and losing no source event
|
||
|
|
|
||
|
|
## M2 — interface and packaging
|
||
|
|
|
||
|
|
- [ ] axum configuration UI, bound to 127.0.0.1
|
||
|
|
- [ ] OAuth loopback redirect handler
|
||
|
|
- [ ] systemd user units: `calcalist.service` (oneshot) and `calcalist.timer`
|
