Changelog

All notable changes to phil/circuit-breaker-bundle will be documented in this file.

Updates should follow the Keep a CHANGELOG principles.

NEXT - YYYY-MM-DD

Added

• PhilCircuitBreakerBundle and the phil_circuit_breaker configuration: the clock, the store of states, the cache pool of the default store, and the circuits, each with its policy — its slowness threshold and slow call rate included — and the HTTP client to put behind it.
• ConfiguredCircuitBreakers: the circuits of the configuration, read once at load time so that a bad key or policy fails the container build with its path.
• CacheCircuitStateStore: the states in a PSR-6 cache pool shared by the workers, under the prefix phil_circuit_breaker.circuit., the slow calls of the window with the other counters; an entry the pool lost or holds in another shape reads as a closed circuit.
• CircuitBreakingHttpClient and CircuitOpen: an HTTP client behind its circuit, a request refused before it leaves while the circuit is open, a 5xx or a transport error counted as a failure, any other answer as a success; each request measured up to its answer or its error — the transport's total_time, or the monotonic time since it was made —, its duration recorded with the outcome so that slow requests count.
• The overrides: the services tagged phil_circuit_breaker.override asked together by CircuitOverrides, a service implementing CircuitOverride tagged by autoconfiguration.
• The parameter phil_circuit_breaker.circuit_keys, the keys of the declared circuits.
• CircuitBreakerDataCollector, CircuitsReport and the profiler panel of the circuits: the state of each one at the end of the request, and how many are not closed.
• The documentation in doc/, one file per topic, indexed by the README.
• CONTRIBUTING.md, SECURITY.md and CODE_OF_CONDUCT.md.
