Phase 1 of the CRL/OCSP responder bundle. Adds:
* migration 000019 — crl_cache (one row per issuer; pre-generated CRL DER,
monotonic crl_number per RFC 5280 §5.2.3, this_update/next_update,
generation duration metric, revoked_count) + crl_generation_events
(append-only audit log of every regeneration attempt, succeeded
+ error fields for ops grep)
* internal/domain/crl_cache.go — CRLCacheEntry + IsStale helper +
CRLGenerationEvent (raw DER omitted from JSON to avoid bloating
admin responses; CRLDERBase64 field for explicit transit shaping)
* internal/repository/interfaces.go — CRLCacheRepository interface
(Get / Put / NextCRLNumber / RecordGenerationEvent /
ListGenerationEvents)
* internal/repository/postgres/crl_cache.go — Postgres impl with
SERIALIZABLE-isolated NextCRLNumber to defeat the monotonicity
race between concurrent generations of the same issuer
* internal/repository/postgres/crl_cache_test.go — testcontainers
suite (round-trip, overwrite, monotonicity, event recording,
failure-event-with-error)
No behavior change at the HTTP layer yet — Phase 3 wires the cache into
GetDERCRL via a new CRLCacheService + crlGenerationLoop.

-- CRL cache + generation event log for the scheduler-driven CRL
|
|
-- pre-generation work (CRL/OCSP responder bundle).
|
|
--
|
|
-- Before this migration the CRL endpoint at /.well-known/pki/crl/{issuer_id}
|
|
-- regenerated the entire CRL on every HTTP request — every relying party
|
|
-- fetch hit the certificate_revocations table, built the entry list,
|
|
-- signed the CRL, and discarded the result. For a busy CA with many
|
|
-- relying parties this DOSes itself.
|
|
--
|
|
-- After this migration the scheduler's crlGenerationLoop pre-generates
|
|
-- CRLs at a configurable interval (default 1h, env var
|
|
-- CERTCTL_CRL_GENERATION_INTERVAL) and the HTTP handler reads from
|
|
-- crl_cache. On cache miss / staleness the cache service triggers an
|
|
-- immediate generation via singleflight (to coalesce concurrent miss
|
|
-- requests for the same issuer into a single generation).
|
|
--
|
|
-- Idempotent: every CREATE uses IF NOT EXISTS so re-running the
|
|
-- migration is safe (matches the project's migration convention).
