Polly 5.6.1

v5.0 is a major release with significant new resilience policies: Timeout; Bulkhead Isolation; Fallback; Cache; and PolicyWrap. See release notes back to v5.0.0 for full details. 5.6.1 --------------------- - Extend PolicyWrap syntax with interfaces 5.6.0 --------------------- - Add ability to handle inner exceptions natively: .HandleInner<TEx>() - Allow WaitAndRetry policies to calculate wait based on the handled fault - Add the ability to access the policies within an IPolicyWrap - Allow PolicyWrap to take interfaces as parameters - Bug fix: set context keys for generic execute method with PolicyWrap - Bug fix: generic TResult method with non-generic fallback policy - Performance improvements 5.5.0 --------------------- - Bug fix: non-generic CachePolicy with PolicyWrap - Add Cache interfaces 5.4.0 --------------------- - Add CachePolicy: cache-aside pattern, with interfaces for pluggable cache providers and serializers. - Bug fix: Sync TimeoutPolicy in pessimistic mode no longer interposes AggregateException. - Provide public factory methods for PolicyResult, to support testing. - Fallback delegates can now take handled fault as input parameter. 5.3.1 --------------------- - Make ISyncPolicy<TResult> public - (Upgrade solution to msbuild15) 5.3.0 --------------------- - Fix ExecuteAndCapture() usage with PolicyWrap - Allow Fallback delegates to take execution Context - Provide IReadOnlyPolicyRegistry interface 5.2.0 --------------------- - Add PolicyRegistry for storing and retrieving policies. - Add interfaces by policy type and execution type. - Change .NetStandard minimum support to NetStandard1.1. 5.1.0 --------------------- - Allow different parts of a policy execution to exchange data via a mutable Context travelling with each execution. 5.0.6 --------------------- - Update NETStandard.Library dependency to latest 1.6.1 for .NetStandard1.0 target. Resolves compatibility for some Xamarin targets. 5.0.5 --------------------- - Bug fix: Prevent request stampede during half-open state of CircuitBreaker and AdvancedCircuitBreaker. Enforce only one new trial call per break duration, during half-open state. - Bug fix: Prevent duplicate raising of the onBreak delegate, if executions started when a circuit was closed, return faults when a circuit has already opened. - Optimisation: Optimise hotpaths for Circuit-Breaker, Retry and Fallback policies. - Add NoOpPolicy: NoOpPolicy executes delegates without intervention; for eg stubbing out Polly in unit testing. 5.0.4 pre --------------------- - (.NET40Async package changes only) 5.0.3 RTM --------------------- - Refine implementation of cancellable synchronous WaitAndRetry - Minor breaking change: Where a user delegate does not observe cancellation, Polly will now honour the delegate's outcome rather than throw for the unobserved cancellation (issue 188). 5.0.2 alpha --------------------- - .NETStandard1.0 target: Correctly state dependencies. - .NETStandard1.0 target: Fix SemVer stamping of Polly.dll. - PCL259 project and target: Remove, in favour of .NETStandard1.0 target. PCL259 targets are still supported, via .NETStandard1.0 target. - Mark Polly.dll as CLSCompliant. 5.0.1 alpha --------------------- - Add a .NETStandard1.0 target. 5.0.0 alpha --------------------- A major release, adding significant new resilience policies: - Timeout policy: allows timing out any execution - Bulkhead isolation policy: limits the resources consumable by governed actions, such that a faulting channel cannot cause cascading failures. - Fallback policy: provides for a fallback execution or value, in case of overall failure - PolicyWrap: allows flexibly combining Policy instances of any type, to form an overall resilience strategy. Other changes include: - Add PolicyKeys and context to all policy executions, for logging and to support later introduction of policy events and metrics. - Add CancellationToken support to synchronous executions. - Add some missing ExecuteAndCapture/Async overloads. - Remove invalid ExecuteAsync overloads taking (but not making use of) a CancellationToken - Provide .NET4.0 support uniquely through Polly.NET40Async package - Retire ContextualPolicy (not part of documented API; support now in Policy base class) - Discontinue .NET3.5 support 4.3.0 --------------------- - Added ability for policies to handle return results. Optimised circuit-breaker hot path. Fixed circuit-breaker threshold bug. 4.2.4 --------------------- - Added overloads to WaitAndRetry and WaitAndRetryAsync methods that accept an onRetry delegate which includes the attempt count. 4.2.3 --------------------- - Cleaned up new Polly.Net40Async NuGet package, removing Polly.dll and unused framework folders. 4.2.2 --------------------- - Add new Polly.Net40Async project supporting async for .NET40 via Microsoft.Bcl.Async. This is available as separate Nuget packages Polly.Net40Async and Polly.Net40Async-signed. 4.2.1 --------------------- - Allowed async onRetry delegates to async retry policies. 4.2.0 --------------------- - Added AdvancedCircuitBreaker - Thanks to @reisenberger and @kristianhald 4.1.2 --------------------- - Fixed an issue with the onReset delegate of the CircuitBreaker. 4.1.1 --------------------- - Add ExecuteAndCapture support with arbitrary context data - Thanks to @reisenberger 4.1.0 --------------------- - Add Wait and retry forever policy - Thanks to @nedstoyanov - Remove time-limit on CircuitBreaker state-change delegates - Thanks to @reisenberger 4.0.0 --------------------- - Add async support and circuit-breaker support for ContextualPolicy - Add manual control of circuit-breaker (reset and manual circuit isolation) - Add public reporting of circuit-breaker state, for health/performance monitoring - Add delegates on changes of circuit state - Thanks to @reisenberger 3.0.0 --------------------- - Add cancellation support for all async Policy execution - Thanks to @reisenberger 2.2.7 --------------------- - Fixes an issue where continueOnCapturedContext needed to be specified in two places (on action execution and Policy configuration), when wanting to flow async action execution on the captured context - Thanks to @reisenberger - Fixes excess line ending issues 2.2.6 --------------------- - Async sleep fix, plus added continueOnCapturedContext parameter on async methods to control whether continuation and retry will run on captured synchronization context - Thanks to @yevhen 2.2.5 --------------------- - Policies with a retry count of zero are now allowed 2.2.4 --------------------- - Add .NET Core support 2.2.3 --------------------- - Fix PCL implementation of `SystemClock.Reset` - Added ability to capture the results of executing a policy via `ExecuteAndCapture` 2.2.2 --------------------- - Added extra `NotOnCapturedContext` call to prevent potential deadlocks when blocking on asynchronous calls 2.2.1 --------------------- - Replaced non-blocking sleep implementation with a blocking one for PCL 2.2.0 --------------------- - Added Async Support (PCL) - PCL Profile updated from Profile78 -> Profile 259 - Added missing WaitAndRetryAsync overload 2.1.0 --------------------- - Added Async Support (.NET Framework 4.5 Only) 2.0.0 --------------------- - Added Portable Class Library - The "Polly" NuGet package is now no longer strongly named.
