Expose the existing Rust job runtime through a feature-packaged Haskell API. Add Conduit polling, linear one-shot claim ownership with fenced settlement tokens, and real-engine tests for atomic enqueue, retries, deferrals, renewal, and dead lettering.

Keep the binding on GHC 9.14.1 while disabling only linear-base's incompatible upstream inspection tests; the event-sorcery test suites remain enabled.

Closes #69.


This is part 15 of 32 in a stack made with GitButler:

Walkthrough

Changes

The Haskell binding now supports durable job creation, polling, claiming, lease management, settlement, streaming, wire encoding, ABI errors, and ABI v3 tagged calls. It adds runtime and wire-format tests plus Cabal and Nix dependency wiring.

Inline comments:
In `@bindings/haskell/src/EventSorcery/Engine/Internal.hs`:
- Around line 388-405: Update callWithTag to inspect the value read from output
after callWithoutOutput succeeds, and convert unwrittenTag into the existing
unknown-tag EngineError before returning. Preserve successful tag values,
including any legitimate ABI-defined tags, while keeping call failures
unchanged.
- Line 143: Document in SPEC.md that the minimum ABI minor version is 3,
matching the minimumAbiMinor constant and openStore validation. State that ABI
0.2 engines, including stream-only deployments, are no longer compatible with
the bindings.
- Around line 509-522: Update SPEC.md’s JOB_REFUSAL specification to document
the six canonical reason literals used by decodeJobRefusal: job attempt counter
exhausted, invalid job claim policy, job aggregate refused the settlement,
claimed job payload is not opaque bytes, claimed job payload contains an invalid
byte, and claimed job payload exceeds the ABI payload limit. State that existing
values must not be reworded and that new refusal cases must be added as new
leaves; do not introduce a numeric subtag.

In `@bindings/haskell/src/EventSorcery/Job.hs`:
- Around line 256-262: Correct the documentation for ClaimedJob and related
claim-settlement APIs to state that linear consumption prevents reusing the
claim, while engine-side fencing rejects duplicate or superseded settlements; do
not claim the type system bounds token multiplicity. Record this ownership
decision in an ADR, covering settlementToken and JobSpec.releaseClaim, and apply
the same clarification to the corresponding documentation around the other noted
lines.

In `@bindings/haskell/test/JobSpec.hs`:
- Around line 128-137: Expand the JobSpec behavior tests to exercise the
settlement outcomes SettlementFenced, LeaseLost, JobContended, JobSkipped, and
JobRefused through the real engine, including a superseded-claim scenario that
produces SettlementFenced rather than only InvalidState. Verify the
corresponding lease and settlement results end to end; if SettlementFenced or
LeaseLost cannot be emitted by this binding, remove those constructors and their
decoding paths instead.

In `@bindings/haskell/test/WireSpec.hs`:
- Around line 82-98: Export encodeAcknowledge, encodeRetry, encodeDefer, and
encodeDeadLetter from EventSorcery.Job, then add WireSpec byte-fixture tests
covering each settlement encoder, including all dead-letter reason tags. Extend
decoding tests with JobContended and JobSkipped cases through decodeClaimWire,
preserving the existing request encoding coverage.

In `@flake.nix`:
- Line 48: Update the linear-base package override in the Nix package set to
remove dontCheck and keep both test suites enabled. If inspection assertions are
incompatible, disable only those assertions or switch
haskellPackages.linear-base to a compatible revision.

⚙️ CodeRabbit configuration file

Focus on providing constructive criticism. Whenever you see a suboptimal approach, suggest more idiomatic or robust alternative(s). Flag potential footguns. Suggest FP alternatives to mutable/imperative code. Point out architectural flaws like leaky abstractions, tight coupling, wrong level of abstraction, poor type modeling, over-abstraction, unclear domain boundaries. Code should generally be organized based on business concerns rather than technical aspects - suggest improvements if you find violations. Point out gaps in test coverage but suggest tests that are not too coupled to the implementation and actually test domain invariants and business logic

Learning: In `crates/event-sorcery/src/job_backend.rs`, `JobClaimHandle` is deliberately non-serializable. It contains private fencing identity, so foreign-language bindings must retain it in trusted process memory and expose only a binding-owned opaque token; accepting caller-provided serialized handles could permit forged claim state.

Learning: In `crates/event-sorcery/src/lib.rs`, the crate-root `engine` module should remain private (`mod engine;`). Rust permits descendant modules, including `crates/event-sorcery/src/job_sqlite.rs` and `crates/event-sorcery/src/sqlite_event_repository.rs`, to access it through `crate::engine`; it does not need `pub(crate)` visibility for that internal access.

Document the ABI minor floor as 3

The Rust engine exports ABI 0.3, and openStore rejects engines below minor 3. Add the raised floor and its compatibility impact to SPEC.md; it prevents bindings from opening ABI 0.2 engines, including stream-only deployments.

Detect the unwritten sentinel inside callWithTag.

The comment states that a call which wrote no tag is reported as an unknown tag. callWithTag does not do that; it returns Right 255. The guarantee currently depends on each caller in EventSorcery.Job having no case for 255. That contract is implicit and breaks if the ABI later defines tag 255, or if a caller uses a total mapping.

Reject the sentinel where it is poked, so the invariant is local.

The linear claim does not prevent double settlement; the documentation says it does.

Lines 259-260 state that consuming the claim linearly stops a worker settling the same claim twice. settlementToken returns Ur JobSettlementToken. Ur is unrestricted, so the token escapes the claim body and can be passed to acknowledgeJob, retryJob, deferJob and deadLetterJob any number of times. JobSpec.releaseClaim does exactly that, and one test settles a stale token and then a current token.

Linearity here only guarantees that ClaimedJob is consumed once. It does not bound settlement. Double settlement is prevented by engine-side fencing, which is why SettlementFenced exists.

Two options:

  • Keep the current shape and correct the comment. State that the linear claim mints one token and that fencing, not the type system, rejects a superseded settlement.
  • Enforce the invariant in types. Do not return the token to the caller. Give the claim body a linear settlement continuation, so the token cannot outlive the claim.

The type-level option is the stronger design, but it changes the public API. Choose one deliberately and record the decision, because it is an architectural choice about where the ownership guarantee lives.

Based on learnings, JobClaimHandle carries private fencing identity and bindings must expose only a binding-owned opaque token; the unexported JobSettlementToken constructor satisfies that part, so this comment concerns the multiplicity guarantee only. As per coding guidelines, "When changing direction or making an important undocumented architectural decision, obtain confirmation; record significant decisions as ADRs under adrs/."

Cover the outcomes the settlement model depends on.

The suite never observes SettlementFenced, LeaseLost, JobContended or JobSkipped from the real engine. The fencing test reaches a superseded claim, but the engine answers InvalidState "claim handle is invalid" for both the renewal and the stale acknowledgement, so SettlementFenced is never produced.

This matters beyond coverage. The safety argument for the claim API is that the engine fences a superseded settlement. No test demonstrates that path, so decodeSettlement 1 and decodeLeaseResult 1 are unexercised end to end.

Add cases that produce these outcomes, or confirm the engine cannot return SettlementFenced and LeaseLost through this binding and remove the constructors. Also cover the JobRefused error, which the wire tests decode but no behaviour test triggers.

Pin the settlement request encodings.

The suite pins five request encodings. It pins none of the four settlement encodings: encodeAcknowledge, encodeRetry, encodeDefer and encodeDeadLetter. Those four are not exported from EventSorcery.Job, while the five tested encoders are. The split is arbitrary, and it leaves the settlement half of the wire contract unverified.

encodeDeadLetter writes deadReasonTag, which maps four reasons to 0, 1, 2 and 3. If a value is wrong, the engine records the wrong reason for a job leaving the queue, and no test fails.

Export the four settlement encoders and add byte fixtures for them. Also add decoding cases for JobContended and JobSkipped, which decodeClaimWire handles but no test exercises.

As per coding guidelines, "All new or modified logic must have corresponding test coverage."

linear-base 0.5.0 source test-suite inspection-testing tasty-inspection-testing

💡 Result:

Linear-base 0.5.0 is a standard library for Haskell applications utilizing linear types, released on April 7, 2025 [1][2]. It is designed to work with the -XLinearTypes language extension introduced in GHC 9 [1][3]. Inspection testing in Haskell is enabled by the inspection-testing package, which provides a GHC plugin to embed and verify assertions about intermediate compiler code (Core) [4][5]. The tasty-inspection-testing package acts as an integration layer, allowing these inspection-testing obligations to be seamlessly incorporated into tasty test suites [6][7]. While linear-base itself focuses on providing linear type primitives, it has historically utilized inspection-testing in its own test suite to verify code properties [6][7]. Key components involved include: 1. inspection-testing: The core GHC plugin that performs the actual verification of code properties, such as checking for the absence of allocation, verifying equality of definitions, or ensuring strictness properties [4][5][8]. 2. tasty-inspection-testing: A bridge library that converts inspection-testing obligations into tasty TestTrees, enabling them to be run alongside standard unit or property tests [6][9][10]. To use these in a project, developers typically define obligations using TemplateHaskell and the inspection-testing API (e.g., inspect or inspectTest) [11][12]. When integrated with tasty, tasty-inspection-testing automates the plugin enabling process, meaning manual configuration of the GHC plugin is often unnecessary when using the inspectTest function [13].

site:github.com/NixOS/nixpkgs "dontCheck =" haskell

💡 Result:

In the context of the Nix package manager (nixpkgs), dontCheck is a helper function used in Haskell package derivations to disable the execution of a package's test suite [1][2]. When applied to a Haskell package, dontCheck sets the doCheck attribute to false [1][3][4]. This is useful when a package has a broken, flaky, or otherwise problematic test suite that prevents the package from building successfully [1]. Key points regarding dontCheck: - Functionality: It is a wrapper that modifies a derivation by setting doCheck = false, ensuring the test phase is skipped [2][3][4]. - Conditional usage: There is also a variant called dontCheckIf, which allows you to disable tests only if a specific condition is met (e.g., based on the operating system or architecture) [1][2][5]. - Limitations: It is important to note that while dontCheck disables the execution of the tests, it does not necessarily remove the dependencies that were required to run the test suite [6]. Those dependencies may still be present in the build environment. - Nixpkgs usage: You will typically see it used in overrides within Nix expressions, such as in configuration-common.nix, to handle packages with known test issues [5].

github tweag linear-base linear-base.cabal test-suite 0.5.0

💡 Result:

In version 0.5.0 of the tweag/linear-base Haskell package, the linear-base.cabal file defines two test suites [1]: 1. test: This is the main test suite, which uses exitcode-stdio-1.0 and runs the module Main.hs from the test directory [1]. It includes various modules such as Test.Data.Destination, Test.Data.Functor.Linear, Test.Data.List, Test.Data.Mutable.Array, Test.Data.Mutable.HashMap, Test.Data.Mutable.Set, Test.Data.Mutable.Vector, Test.Data.Polarized, Test.Data.Replicator, and Test.Data.V [1]. Its dependencies include inspection-testing, tasty-inspection-testing, base, linear-base, containers, hedgehog, tasty, tasty-hedgehog (>= 1.2), mmorph, vector, and linear-generics [1]. 2. test-examples: This test suite also uses exitcode-stdio-1.0 and runs Main.hs from the test-examples directory [1]. It includes the modules Test.Foreign and Test.Simple.Quicksort [1]. Its dependencies include base, linear-base, tasty, tasty-hedgehog, hedgehog, and examples [1]. The 0.5.0 version of linear-base was released on April 7, 2025 [2][3]. The cabal file for this version transitioned to using shared imports (build-opts and rts-opts-multithread) for these test suites [1][2].

Keep the linear-base checks enabled.

dontCheck skips both linear-base test suites, including ordinary Hedgehog/Tasty tests and example tests. Disable only the incompatible inspection assertions, or use a compatible package revision.

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In `@flake.nix` at line 48, Update the linear-base package override in the Nix
package set to remove dontCheck and keep both test suites enabled. If inspection
assertions are incompatible, disable only those assertions or switch
haskellPackages.linear-base to a compatible revision.
