Stratara.Validation

Derived. The behaviour described here is specified under openspec/specs/. Those specifications are the source; this page explains and illustrates them.

License: MIT.

Vendor-neutral request validation for Stratara's CQRS pipeline. A mediator pipeline behavior runs your IValidator<T> implementations before the handler and throws an aggregated StrataraValidationException when validation fails — no third-party validation dependency in the default path.

Quick start

// 1. Register the behavior (outermost) + discover validators.
builder.Services
    .AddStrataraValidation()
    .AddValidatorsFromAssemblyContaining<IAppMarker>();

// 2. Write a validator (the contracts live in Stratara.Abstractions.Validation).
public sealed class CreateOrderValidator : IValidator<CreateOrder>
{
    public ValueTask<ValidationResult> ValidateAsync(CreateOrder cmd, CancellationToken ct = default)
        => ValueTask.FromResult(string.IsNullOrWhiteSpace(cmd.CustomerId)
            ? new ValidationResult([new ValidationFailure(nameof(cmd.CustomerId), "Customer is required.")])
            : ValidationResult.Success);
}

// 3. Catch the failure in your global handler and map it to your error model.
catch (StrataraValidationException ex)
{
    // ex.Failures -> RFC-7807 ProblemDetails 400, your error codes, etc.
}

How it works

  • AddStrataraValidation() registers IPipelineBehavior for both request shapes (IRequest and IRequest<TResult>). Register it before other behaviors so validation runs outermost — before authorization, auditing, and the handler.
  • All validators for a request run; their failures are aggregated.
  • Severity policy: only ValidationSeverity.Error blocks (throws StrataraValidationException). Warning and Info failures pass through and are logged.

Contracts

The validation contracts (IValidator<T>, ValidationResult, ValidationFailure, ValidationSeverity, StrataraValidationException) live in Stratara.Abstractions (namespace Stratara.Abstractions.Validation) so consumers can implement validators and catch the exception without referencing this behavior package.

The contract shape is FluentValidation-compatible; an optional Stratara.Validation.FluentValidation adapter can be shipped to plug FluentValidation validators into the same pipeline.

A fix for hosts on the Orleans execution model. A store reader that catches up a large backlog and a singleton
work that runs long now answer their keep-alive, so neither leaves reminder errors in the silo's log. A silo that
joins while a singleton work runs long on another silo no longer fails its start. No API change, no schema change
and no migration.

### Fixed

- **A busy store reader or singleton work answers its keep-alive.** On the Orleans execution model, a projection or
 saga reader that caught up a backlog for longer than the runtime's response timeout made its keep-alive tick wait
 behind the catch-up, and Orleans logged `Could not deliver reminder tick` at Error, once per partition and
 keep-alive period. A singleton work whose run outlasted the timeout did the same. Nothing was lost, but a large
 catch-up left dozens of errors on the silo. The keep-alive and the poll now start a catch-up where none is
 running and do not wait for it. A partition is still read by one catch-up at a time, and a commit during a
 catch-up is still applied by it. A singleton work's keep-alive interleaves with its run, and runs still never
 overlap.
- **A silo starts while a singleton work runs long.** A silo that started while a singleton work it registers ran
 longer than the response timeout on another silo waited for that run in its own start. The start then failed
 with a `TimeoutException`. The call a starting silo makes to each singleton work and store reader now
 interleaves, so the start goes on.
- *Operate the Orleans execution model* says that a durable timer whose handler outlasts the response timeout
 still makes Orleans log `Could not deliver reminder tick` for that tick, and that the line says nothing about
 the timer. It also says that, outside a deploy, the line now points to an unreachable store reader or singleton
 work rather than a busy one.
