When postponing the delivery time of an already signed/sent will, the user
was asked to sign the on-chain invalidation transaction twice before the new
(postponed) will could be built.
Root cause: after the invalidation tx was broadcast, on_success_invalidate
restarted task_phase1 to rebuild the will, but the old will items were still
marked COMPLETE/PUSHED with their original tx.locktime (the on-chain
invalidation did not update the in-memory status). The postpone check therefore
fired WillPostponedException a second time, requesting another invalidation.
Fix:
- Add Will.mark_invalidated_by_tx(will, tx): marks INVALIDATED every valid will
item that spends a prevout consumed by the just-broadcast invalidation tx.
Setting INVALIDATED clears the VALID flag, removing those items from
only_valid_list so the postpone/expire check no longer fires.
- Call it from loop_broadcast_invalidating after a successful broadcast (txid
obtained) and persist via save_willitems. On the phase-1 restart the old will
is no longer VALID, so the will is rebuilt directly: a single invalidation
signature followed by the new will.
Tests: add test_will_mark_invalidated_by_tx and
test_will_mark_invalidated_by_tx_no_match plus the WillPostponedException
hierarchy assertion. 184 tests pass; smoke and external-zip OK; ruff clean.
Bump version to 0.3.1.
Bump plugin version from 0.2.8 to 0.3.0 in VERSION, manifest.json,
__init__.py and core/plugin_base.py for the 0.3.0 release (postpone
invalidation safety + Server status column).
