Test, Build, and Deploy / test-build-deploy (push) Failing after 18s
delivery_worker state shape gains :next_retry proplist alongside
the existing :attempts:
[{peer, _}, {pending, _}, {attempts, [{Cid, N}]},
{next_retry, [{Cid, NextRetryAt}]}, {dead_letter, _},
{dispatch_fn, _}]
New pure-functional exports:
record_failure_pure/3(Cid, Now, State)
Bumps :attempts for Cid. On the 6th failure
(backoff_for returns dead_letter) moves the matching
activity from :pending to :dead_letter and clears the
:next_retry entry. Otherwise sets next_retry to
Now + backoff_for(NewAttempts).
record_success_pure/2(Cid, State)
Clears both :attempts and :next_retry for Cid.
next_due_pure/2(Now, State)
Returns cids whose retry time has passed (insertion
order preserved so the worker drains in FIFO retry
order).
attempts_for/2, next_retry_at/2, dead_letter_list/1
Read-side accessors.
Internal helper move_to_dead_letter/2 + take_by_cid/4 walks
:pending to find the matching activity by cid.
11/11 in next/tests/delivery_retry.sh covering:
- fresh state: 0 attempts / undefined retry / [] dead_letter
- record_failure bumps to 1
- record_failure sets next_retry_at = Now + 30 (slot 1)
- second failure: attempts=2, NextRetryAt = Now + 300 (slot 2)
- record_success clears both
- next_due returns due cids
- next_due empty before due
- 6th failure -> dead-letter; activity out of :pending
- dead-lettered cid removed from :next_retry
- per-cid isolation: success on one doesn't disturb another
delivery_worker.sh 17/17 unchanged (new exports are additive).
Blockers added:
#2 — Native http-request primitive missing in bin/sx_server.ml
(briefing assumed it existed; only http-listen exists).
Belongs to loops/fed-prims. Step 8e wrapper waits for
the native.
#3 — erlang:send_after-style timer primitive missing. Needed
for the real retry loop. Belongs to loops/erlang. 8b-pure
captures the semantics so 8b-timer is a 1-shot wiring
when the primitive lands.
Conformance preserved at 761/761.
