Polly-Signed 5.0.3

Polly is a .NET 4.0 / 4.5 / .NET Standard 1.0 library that allows developers to express resilience and transient fault handling policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation and Fallback in a fluent and thread-safe manner.

There is a newer version of this package available.

Release Notes

v5.0 is a major release with significant new resilience policies: Timeout; Bulkhead Isolation; Fallback; and PolicyWrap.  See release notes back to v5.0.0 for full details.

    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`

    1.1.0
    ---------------------
    - Added additional overloads to Retry
    - Allow arbitrary data to be passed to policy execution
