Typed Context classes (src/Log/Context/) carry per-context JSON Schemas (docs/schemas/context/), and SafeSemanticLogger guarantees logging never breaks cache reads/writes (NullSemanticLogger is the no-op default). Adds koriym/semantic-logger ^0.8.0; vendor/bin/stree renders the cache log as a tree (demo/run-dependency.php, demo/run-donut.php). The legacy RepositoryLogger interface stays bound for BC but receives no internal events. The multi-embed dependency fix and diamond tests are intentionally excluded here; they already shipped in 1.16.1 (#177). --- CHANGELOG.md | 15 ++ composer.json | 1 + demo/run-dependency.php | 60 ++---

Renamed to "ttl" (the public ResourceStorage::saveDonut() parameter keeps its name for BC, with a comment noting it carries the donut entry TTL). - A saver that returned false still logged a successful-looking save. All five save contexts now carry the pool's "saved" outcome; the schemas mark it required and explain that false means NOT cached. - A cache-server outage was indistinguishable from a cold miss. The interceptors now emit a cache_error event (uri + throwable message) before the warning, so a cache_miss after it reads as degradation. Also clamp negative TTLs to 0 at the QueryRepository/ResourceStorage boundary (past expiryAt, negative expirySecond or ttl argument), matching the "minimum": 0 the schemas declare, and reword invalidate.json's "cdn" description to the fail-closed semantics the code implements. --- docs/schemas/context/cache_error.json | 21 +++++++++++++++++++ docs/schemas/context/invalidate.json | 2 +- docs/schemas/context/save_donut.json | 10 +++++++-- docs/schemas/context/save_donut_view.json | 10 +++++++-- docs/schemas/context/save_etag.json | 7 ++++++- docs/schemas/context/save_value.json | 8 +++++++- docs/schemas/context/save_view.json | 8 +++++++- src/AbstractDonutCacheInterceptor.php | 4 +++- src/CacheInterceptor.php | 6 +++++- src/CommandContextFactory.php | 3 ++- src/Log/Context/CacheErrorContext.php | 25 +++++++++++++++++++++++ src/Log/Context/SaveDonutContext.php | 3 ++- src/Log/Context/SaveDonutViewContext.php | 3 ++- src/Log/Context/SaveEtagContext.php | 1 + src/Log/Context/SaveValueContext.php | 1 + src/Log/Context/SaveViewContext.php | 1 + src/QueryRepository.php | 7 +++++-- src/ResourceStorage.php | 24 ++++++++++++++-------- 18 files changed, 121 insertions(+), 23 deletions(-) create mode 100644 docs/schemas/context/cache_error.json create mode 100644 src/Log/Context/CacheErrorContext.php diff --git a/docs/schemas/context/cache_error.json b/docs/schemas/context/cache_error.json new file mode 100644 index 00000000..bdf3ae95 --- /dev/null +++ b/docs/schemas/context/cache_error.json @@ -0,0 +1,21 @@ +{ + "$schema": "https://json-schema.org/draft/2020-12/schema", + "$id": "https://bearsunday.github.io/BEAR.QueryRepository/schemas/context/cache_error.json", + "title": "cache_error", + "description": "Event: the cache layer itself errored (e.g. cache server down).

FakeErrorCache now throws on getItems with a "cache server down" message (TagAwareAdapter::getItem delegates to getItems). - A pool that rejects on commit yields saved=false in save_value, and a negative ttl / past expiryAt is pinned to clamp to 0. --- tests/Fake/FakeErrorCache.php | 4 +- tests/GracefulLoggingTest.php | 48 +++++++++++++++++ tests/QueryRepositoryTest.php | 16 ++++++ tests/ResourceStorageTest.php | 56 +++++++++++++++++++ tests/SafeSemanticLoggerTest.php | 20 +++++++ tests/SemanticLogSchemaTest.php | 83 ++++++++++++++++++++++++++-- tests/SemanticLogTreeTrait.php | 92 ++++++++++++++++++++++++++++++++ 7 files changed, 314 insertions(+), 5 deletions(-) diff --git a/tests/Fake/FakeErrorCache.php b/tests/Fake/FakeErrorCache.php index 13b0efa8..26ca5c3c 100644 --- a/tests/Fake/FakeErrorCache.php +++ b/tests/Fake/FakeErrorCache.php @@ -14,12 +14,12 @@ class FakeErrorCache implements AdapterInterface { public function getItem($key): CacheItem { - throw new RuntimeException();

save_etag/save_donut_view rename surrogateKeys to tags for consistency - Add put_skipped context (uri + reason: etag-present | error-code) emitted when a cacheable result is intentionally not stored - Command interceptors always open a command scope, skip commands on code >= 400, and always close with command_result; CommandContext gains a required source field (interceptor basename) - Remove assert($saved) in ResourceStorage::saveDonut so failed donut writes surface as warnings instead of relying on zend.assertions - Bound command_result code to 100-599 and fix put_donut / manual_store_result / command / invalidate schema descriptions;

charset=UTF-8 Content-Transfer-Encoding: 8bit - invalidate cdn is now tri-state: purged (a configured purger ran), failed (it threw), skipped (the bound purger is NullPurger, no CDN configured) — a no-op purger no longer reads as a successful purge - cache_error gains a required operation field (read|write) naming the failing side; both read interceptors and the write path set it - put_skipped gains an optional code (the actual response status when reason is error-code), is now also emitted by CacheInterceptor on a non-200 GET (before the purge), and gains a not-cacheable reason emitted by DonutRepository when a refreshed donut page has no page-level entry to save; its description is reworded to state facts without judging whether skipping was correct - save_etag gains the ttl field it previously dropped, and all save_* ttl descriptions state the 31536000 never-expiry convention so a blind reader does not read the log as a TTL-driven cache - refresh_donut description corrected (template hit + re-render, not a cache-miss rebuild); cache_hit close description now states it reports only the final layer's outcome - SafeSemanticLogger no longer silently wipes a broken session: the recovery flush returns a log_session_broken sentinel scope carrying the cause, falling back to the empty log only if the sentinel itself fails (never-throw guarantee stands) - The invalidate schema's pre-write-cleanup rule is redefined as a machine-applicable predicate: a later same-scope save_* event whose tags include the invalidate's tags — regardless of scope type, with depends_on possibly in between;
