From 05d0b2af0230c57d94aaeb123b440cf5a2e59a74 Mon Sep 17 00:00:00 2001 From: Kai <450507+neko-kai@users.noreply.github.com> Date: Wed, 13 May 2026 22:49:23 +0100 Subject: [PATCH 01/70] Bifunctorization PR-01: introduce Bifunctorized opaque type and companion First step in replacing the Quasi* family of compatibility typeclasses with a unified bifunctor scheme via an opaque newtype that lifts a monofunctor F[_] into a bifunctor Bifunctorized[F, +E, +A]. Pure plumbing only -- no cats-effect typeclass instances, no submerging logic; those land in PR-02/PR-04/PR-05. Design (see docs/drafts/20260513-2106-bifunctorization-plan.md): - Abstract type member in object companion, erased via asInstanceOf (no AnyVal wrapper, no Scala-3 opaque type) so the wrapper is unboxed and bifunctorize(fa) eq fa holds at runtime (Goal 4 precondition). - bifunctorize/debifunctorize/implicit conversions exposed at the companion level; assert is private[bio] (internal escape hatch for the forthcoming impl/CatsToBIO). - getClassTag(implicit ClassTag[F[A]]) delegates to the underlying so Bifunctorized[Identity, _, Int] correctly carries Integer.TYPE rather than Object. - No cats imports -- Goal 5 (No-More-Orphans) protected. Tests: 11/11 pass on Scala 3.7.4, 2.13.18, 2.12.21. Coverage spans identity-eq, round-trip, variance widening, both implicit conversions, .toMonofunctor and .unwrap syntax, ClassTag soundness for primitive F[A], and the Goal-4 no-op identity case for a real bifunctor (ZIO). Also commits the project-bootstrap artifacts: the bifunctorization spec (bifunctorization.md), the implementation plan, the prior-art patches referenced by the plan, and the tasks/defects ledgers that will track PRs 02-09 in this milestone and milestones M2-M6 beyond. --- bifunctorization.md | 106 + defects.md | 170 ++ .../20260513-2106-bifunctorization-plan.md | 368 ++++ docs/drafts/prior-art/cats-mtl-619.patch | 1914 +++++++++++++++++ docs/drafts/prior-art/izumi-1766.patch | 535 +++++ .../bio/BifunctorizedTypeTest.scala | 95 + .../izumi/functional/bio/Bifunctorized.scala | 71 + .../scala/izumi/functional/bio/package.scala | 2 + tasks.md | 65 + 9 files changed, 3326 insertions(+) create mode 100644 bifunctorization.md create mode 100644 defects.md create mode 100644 docs/drafts/20260513-2106-bifunctorization-plan.md create mode 100644 docs/drafts/prior-art/cats-mtl-619.patch create mode 100644 docs/drafts/prior-art/izumi-1766.patch create mode 100644 fundamentals/fundamentals-bio/.jvm/src/test/scala/izumi/functional/bio/BifunctorizedTypeTest.scala create mode 100644 fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/Bifunctorized.scala create mode 100644 tasks.md diff --git a/bifunctorization.md b/bifunctorization.md new file mode 100644 index 0000000000..64d39c2482 --- /dev/null +++ b/bifunctorization.md @@ -0,0 +1,106 @@ +# Problem statement + +Izumi Project library ecosystem strives to be compatible with a wide variety of effect types that may (or may not) be used by its users. + +This led to the creation of QuasiIO @fundamentals/fundamentals-bio/src/main/scala/izumi/functional/quasi family of compatibility typeclasses that extract a subset of operations that Izumi Project libraries need from other effect types. The existence of Quasi* typeclass hierarchy is a maintenance burden on the developers and due to its monofunctor nature (previously thought required to support the most common denominator effect types) it prevents usage of typed errors within the Izumi Project libraries themselves. Moreover, due to QuasiIO's direct support for `Identity`, Izumi itself can't use a purely functional style - all maintainers must be aware that the `F` in `F[_]: QuasiIO` is not a lawful monad and operations on it must be carefully suspended manually. + +Following an experiment at conversion of monofunctor effect types to bifunctors (https://github.com/7mind/izumi/pull/1766), we have decided to solve our compatibility problem in a different way. By lifting monofunctor effect types to bifunctors we will get rid of the entire `Quasi*` hierarchy and allow usage of typed errors and purely functional style within Izumi Project library code. However, we also want the usability for monofunctor effect type users not to degrade following that refactoring. + +# Background + +BIO bifunctor typeclass hierarchy is isomorphic to Cats Effect monofunctor typeclass hierarchy. This is currently witnessed only partially by the existence of BIO to CE conversions in fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/CatsConversions.scala, but the opposite conversions, from CE to BIO are missing.

TypedError fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/TypedError.scala exists which converts typed errors into Throwables, but it lacks one detail - we don't want it to be possible for TypedErrors from different `Bifunctorized` effect types to be intermixed together through the Typed error channel. We should add a new type instead that discriminates error origin using `TagK[F]` of the original monofunctor effect type. Note: submarine error handling implies discrimination based on the unique handler, to mimic algebraic effect semantics, which I believe is not necessary for our purpose, type discrimination alone is sufficient. + +### Conversion of effect values + +In order to provide an ability to use an existing monofunctor effect value with bifunctor methods, the following automatic bijection implicit conversions shall be provided: + +```scala +object Bifunctorized { + ... + def bifunctorize(f: F[A]): Bifunctorized[F, Throwable, A] + + def debifunctorize(f: Bifunctorized[F, Throwable, A]): F[A] + + implicit def bifunctorizeConversion(f: F[A]): Bifunctorized[F, Throwable, A] = bifunctorize(f) + implicit def debifunctorizeConversion(f: Bifunctorized[F, Throwable, A]): F[A] = debifunctorize(f) + + implicit final class BifunctorizedSyntax[F[_]](private val f: Bifunctorized[F, Throwable, A]) extends AnyVal { + def toMonofunctor: F[A] = debifunctorize(f) + } + + ...provide Syntax2 conversions in Bifunctorized companion to make BIO syntax available on any Bifunctorized value... +} +``` + +Where in order to make the untyped Throwable error embedded into the monofunctor `F` effect type manipulable via e.g. `Error2#catchAll` and other typed error BIO hierarchy methods, the Throwable error must be Submerged, converted into a typed error during `bifunctorize`. + +In `debifunctorize`, a typed error must be de-Submerged, unwrapped, as its expected to be in order for monofunctor's native methods to work with it. + +Note: where the bifunctorized effect value is a bifunctor already, such as `bifunctorize(Left(new Throwable()))`, no submerging should happen. + +## Transparent bifunctorization at seams + +The Izumi Project external interface seams that previously accepted monofunctor effect types `F[_]`, such as distage/distage-core/src/main/scala/izumi/distage/model/Injector.scala + +```scala +def apply[F[_]: QuasiIO: ...](...): Injector[F] +``` + +Shall now accept bifunctor effect types `F[+_, +_]`: + +```scala +def apply[F[+_, +_]: IO2: ...](...): Injector[F] +``` + +With an overload for monofunctors: + +```scala +def apply[F[_]: ...](...)(implicit F: IO2[Bifunctorized[F, +_, +_]]): Injector[Bifunctorized[F, +_, +_]] +``` + +The BIO syntax on Bifunctorized shall allow users to manipulate their formerly monofunctor effect values in bifunctor way, the implicit conversion `Bifunctorized.bifunctorizeConversion` shall ease the pain of passing in monofunctor values and `.toMonofunctor` method allows return back to monofunctor world. + +# Goals + +1.

Terminates/defects use monofunctor's raw Throwable +3. distage's Injector, bio's Lifecycle and logstage's LogIO entrypoints are transparently bifunctorized/de-bifunctorized for monofunctors. `Identity` is special-cased and goes through a bifunctorization/debifunctorization cycle to `MiniBIO` and back, transparently to the user. +4. Bifunctorization should be a no-op for real bifunctors, that is, `bifunctorize(f: ZIO[ArbiraryEnv, Throwable, A]) eq f` should hold. There should be no error submerging performed for effect types that already support typed errors. +5.

Once PR-04 lands submerging semantics, public `assert` lets a user produce a `Bifunctorized[ZIO, MyTypedError, A]` from a raw `ZIO[Any, Throwable, A]` whose error channel was never submerged — silently breaking the conversion-typeclass invariant. Plan §3.5 enumerates `bifunctorize`/`debifunctorize`/conversions/`toMonofunctor` as the user-facing surface; `assert` is implementation machinery. +**Root cause:** Prior art (izumi-1766.patch line 164) kept `assert` accessible within `object Bifunctorized`'s scope — effectively public, but the surface was small (one file, two internal callers). +**Fix:** Changed signature at Bifunctorized.scala:25 to `private[bio] def assert[...]`.

The round-2 reviewer claimed the deviation was unjustified because `implicitly[ClassTag[Any]]` returns a stable singleton equally well. The round-3 fix subagent attempted the revert and empirically observed the `ct eq getClassTag[...]` assertion FAIL on Scala 2.13.18 (`Object was not the same instance as Any` at BifunctorizedTypeTest.scala:71). Conclusion: on Scala 2.13, `implicitly[ClassTag[Any]]` does NOT produce a stable singleton across invocations — the compiler's ClassTag materializer-macro path (and/or interaction with `asInstanceOf` casts) allocates fresh `ClassTag` instances. `ClassTag.AnyRef`, being a named `val` on the `ClassTag` companion object, IS guaranteed-stable. Both round-1's deviation and the reviewer's refutation cited the wrong cause; the correct cause is that **the *materializer-macro* path (not the explicit `val` lookup) is what `implicitly` resolves to here, and the macro allocates**. +**Root cause:** Scala 2.13's `implicitly[ClassTag[Any]]` resolves via the `ClassTag.apply` factory (not the `ClassTag.Any` stable val), which allocates a fresh `ClassTag(classOf[Object])` each call. This is independent of any subsequent `asInstanceOf` cast. +**Fix:** No source change to `getClassTag` body — original deviation was empirically correct for the wrong stated reason. To prevent a future maintainer from "fixing" this back to `implicitly[ClassTag[Any]]` based on the (incorrect) prior-art-parity argument, see [PR-01-D13] for a defensive comment addition. + +## [PR-01-D13] `getClassTag` lacks an explanatory comment for the non-obvious `ClassTag.AnyRef` choice +**Status:** resolved (superseded by D14 — `ClassTag.AnyRef` itself is unsound, see below) +**Severity:** minor +**Location:** /home/kai/src/izumi/fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/Bifunctorized.scala:40-44 +**Description:** Round 2 already demonstrated that a smart reviewer can be confidently wrong about why `ClassTag.AnyRef` is used here instead of the more idiomatic `implicitly[ClassTag[Any]]`. Without a code-level comment, a future maintainer reading this file in isolation is highly likely to "fix" the deviation, silently breaking the test on Scala 2.13. Defensive comments are exactly the kind of comment CLAUDE.md prescribes ("Only add one when the WHY is non-obvious") — this is the textbook case. +**Suggested fix:** Extend the scaladoc above `getClassTag` (currently lines 40-42) with one extra sentence explaining the choice: +```scala +/** Implicit `ClassTag` shim. Mirrors the prior-art pattern so that `Bifunctorized[F, E, A]` + * is recognised everywhere a `ClassTag[F[A]]` would be (both erase to `Any`). + * + * Body uses `ClassTag.AnyRef` (a stable singleton) rather than `implicitly[ClassTag[Any]]`: + * on Scala 2.13, separate `implicitly[ClassTag[Any]]` invocations return distinct heap + * instances (the materializer macro allocates), which breaks the `eq` invariant the + * test relies on. Do not "revert" to `implicitly[ClassTag[Any]]` without re-running + * `BifunctorizedTypeTest` on Scala 2.13. + */ +``` +Verify the test still passes on all three Scala versions after the doc-comment change. +**Fix:** Comment was added at Bifunctorized.scala:40-48, but the underlying choice it defended (`ClassTag.AnyRef`) is itself unsound — see D14.

For `F = Identity` and `A = Int`, `F[A]` is `Int` (because `Identity[X] = X`), which is NOT `<:< AnyRef`. Returning `ClassTag.AnyRef` means callers that allocate `Array[Bifunctorized[Identity, E, Int]]` get `Array[Object]` when they should get `Array[Int]` (primitive). Prior art has the same flaw (`implicitly[ClassTag[Any]]`); this fix improves on prior art. +**Root cause:** Both the round-1 fix subagent (using `ClassTag.AnyRef`) and the prior art (using `implicitly[ClassTag[Any]]`) treated the abstract-type erasure (Object) as the source of truth instead of the underlying-value class. +**Suggested fix:** Change `getClassTag` to take `ClassTag[F[A]]` as an implicit parameter and cast it: +```scala +/** Implicit `ClassTag` shim. Reflects the runtime class of the underlying `F[A]`. + * + * `Bifunctorized[F, E, A]` is an abstract type, so the compiler's `ClassTag` materializer + * cannot synthesize one directly.

Update the `ClassTag` test to verify what actually matters: that the implicit is summonable and that for a non-primitive `F[A]` the runtime class is the underlying type. Drop or weaken the `eq getClassTag[…]` reference-identity assertion — with the materializer-derived `ClassTag[F[A]]`, two invocations may not be `eq` (and that's fine; the property doesn't matter for correctness). +**Fix:** `getClassTag` at Bifunctorized.scala:48-49 now takes `implicit underlying: ClassTag[F[A]]` and casts it (with explanatory scaladoc replacing D13's defensive comment). Test updated: explicit `dummyFClassTag[A]` implicit provided (required because `DummyF` is a parameterized trait; the materializer cannot synthesize a `ClassTag` for it on Scala 2). New Identity-style test "derive correct ClassTag for primitive F[A]" at lines 82-94 with locally-scoped `type Id[A] = A` plus explicit `idIntClassTag = ClassTag.Int.asInstanceOf[...]` (Scala 2.13's macro doesn't expand local aliases, so the explicit evidence is needed). All 11/11 tests pass on Scala 3.7.4, 2.13.18, 2.12.21.

Cross-cutting architectural decisions (locked) + +### 3.1 Representation of `Bifunctorized[F[_], +E, +A]` + +**Decision.** Abstract type member in an object (`type Bifunctorized[F[_], +E, +A]` defined inside `object Bifunctorized` and inside-erased to `Any` via `asInstanceOf`). No `extends AnyVal`, no Scala-3 `opaque type` on Scala 3 (to keep cross-build symmetric). The same approach as prior-art `izumi-1766.patch` line 155. + +**Rationale.** (1) Variance is straightforward — the abstract type carries `+E, +A` directly. (2) Erasure: `Bifunctorized[F, E, A]` erases to `Object`, identical to `F[A]`'s erasure when `F[_]` itself erases to `Object`, so identity-eq (Goal 4) is preserved automatically. (3) Cross-build: the same syntax works on 2.12/2.13/3 without source-level forks. (4) Allocation: zero (no wrapper class). The trade-off rejected: Scala-3 `opaque type` would be marginally safer (prevents accidental `asInstanceOf` outside the companion), but forces a 2.x shim with a different access pattern, which we judge more burdensome than its safety upside. + +### 3.2 Submerge discriminator type + +**Decision.** +```scala +final class SubmergedTypedError[F[_]] private[bio] ( + val tag: izumi.reflect.LightTypeTag, + val payload: Any, +) extends RuntimeException( + s"Submerged typed error of class=${payload.getClass.getName}: $payload", + payload match { case t: Throwable => t; case _ => null }, + /* enableSuppression = */ true, + /* writableStackTrace = */ false, +) +``` +- Construction: `SubmergedTypedError[F](payload)(implicit tag: TagK[F])` (idempotent: if `payload` is already a `SubmergedTypedError[F]` *with the same tag*, return it as-is). +- Discrimination: by `LightTypeTag` equality (cheap, cached, already on classpath). +- `equals`/`hashCode`: identity-based (RuntimeException default). Two instances with the same payload are *not* equal, which is the right call for exceptions (they may have distinct stack traces). +- `getMessage`: includes payload class for debuggability. Cause-chained to payload if payload `<: Throwable`. +- `fillInStackTrace`: disabled (writableStackTrace=false). Same cost-saving trick as `cats.mtl.Handle.Submarine`'s `NoStackTrace`. +- `catchAll[E]` discrimination (in `CatsToBIO`): + ```scala + F.recoverWith(r.unwrap) { + case SubmergedTypedError(payload) => f(payload.asInstanceOf[E]).unwrap + // un-matched Throwables propagate as defects/Termination + } + ``` +- `catchSome` is implemented as `catchAll` with a `PartialFunction.applyOrElse` over the recovered payload. +- `leftFlatMap` is implemented in terms of `redeem` ↑ `flatMap` ↑ `fail`, no new discriminator path needed. + +**Rationale.** This is the *load-bearing departure from cats-mtl-619.patch*. cats-mtl uses a per-region `Marker = new AnyRef` so each `Handle.allow` creates a distinct discriminator (algebraic-effects-region semantics). The izumi spec rejects that explicitly — we want handlers for the same monofunctor `F` to compose, but handlers for *different* `F`s to be mutually opaque. `TagK[F]` is the natural carrier of "what monofunctor did this error originate from", and `LightTypeTag` is the right equality value (already used throughout izumi-reflect, cheap, structural). + +### 3.3 No-op for actual bifunctors + +**Decision.** Two-instance ladder, mediated by `Predefined.Of[…]`: +- **High priority** (in `BifunctorizedNoOpInstances`): `bifunctorIsAlreadyBifunctor[F[+_, +_]](implicit F: IO2[F]): Predefined.Of[IO2[Bifunctorized[F[ε, _], +_, +_]]]` — uses `F` directly, no submerging. +- **Low priority** (in `CatsToBIOConversions`): `AsyncToBIO[F[_]](implicit F: cats.effect.Async[F], tag: TagK[F]): NotPredefined.Of[Async2[Bifunctorized[F, +_, +_]]]` — does submerge. + +Type-level identity: when `F` is already a bifunctor, `Bifunctorized[F[E, _], E, A] =:= F[E, A]` holds at the *runtime* level (both erase to `Object`), but *not* at the source-type level — there's no `=:=` exposed publicly. The user-facing guarantee is `bifunctorize(f) eq f` for any actual bifunctor `f`, which is sufficient for Goal 4. + +**Rationale.** Replicates the proven `Root.scala` `RootInstancesLowPriority1..10` pattern. The `Predefined`/`NotPredefined` marker traits are precisely the tool to break ambiguity between two competing typeclass instances at differing priorities. + +### 3.4 Identity special-case + +**Decision.** `Identity` goes through a `MiniBIO[Throwable, _]`-based interpreter. The conversion path is: +- `Identity[A] → MiniBIO[Throwable, A]`: wrap in `MiniBIO.Sync(() => Success(a))`, catching any thrown exception into `Termination`. +- `MiniBIO[Throwable, A] → Identity[A]`: run via `MiniBIO.autoRun.autoRunAlways` (rethrows on failure). +- `Bifunctorized[Identity, +_, +_]`: an `IO2`-class instance whose underlying carrier is `MiniBIO[Throwable, _]`. Effectively `Bifunctorized.Identity` is a type alias for `Bifunctorized[Identity, Throwable, _]`, and `IO2[Bifunctorized.Identity]` delegates to `MiniBIO`'s `IO2` instance. + +Mechanism: a dedicated high-priority implicit instance in `BifunctorizedNoOpInstances` for `F = Identity` (placed *above* the cats-effect-mediated path so cats-effect's `Sync[Identity]` (if present) doesn't intercept). + +**Rationale.** Goal 3 requires this exact path: "Identity is special-cased and goes through a bifunctorization/debifunctorization cycle to MiniBIO and back, transparently to the user." Using MiniBIO over Identity gives Identity *lawful* monadic behavior (with suspension), unlike `QuasiIOIdentity` which is unlawful (no actual suspension). The reverse direction (Identity → user-visible) is via `debifunctorize` which runs MiniBIO synchronously. + +### 3.5 Implicit-search surface + +**Decision.** +- `Bifunctorized` companion exposes `bifunctorize` / `debifunctorize` as methods (callable explicitly), and `bifunctorizeConversion` / `debifunctorizeConversion` as implicit conversions (auto-applied at expected-type sites). +- `BifunctorizedSyntax(.toMonofunctor)` provides the dotted syntax `value.toMonofunctor`. Lives in the companion object so it's imported alongside the type. +- BIO syntax (`flatMap`, `map`, `catchAll`, …) on `Bifunctorized[F, E, A]` flows through the existing `Syntax2` machinery automatically — *because* the implicit `IO2[Bifunctorized[F, +_, +_]]` from PR-04/PR-05 is available, the existing `Syntax2.ImplicitPuns` pick it up. No new syntax file required for BIO ops on Bifunctorized. +- CE→BIO ladder (PR-04) lives in `bio/CatsToBIOConversions.scala`. It is *not* mixed into the `bio` package object — users opt in with `import izumi.functional.bio.CatsToBIOConversions.*` or `import izumi.functional.bio.catz_to_bio.*` (analogous to existing `catz`). Rationale: keeping it out of the auto-imported set protects Goal 5 — the package object stays cats-import-free. +- Priorities, top to bottom (most specific first): predefined `IO2[ZIO]`, predefined `IO2[MiniBIO]`, predefined `Error2[Either]`, predefined `Monad2[Identity2]`, no-op bifunctor identity, CE→BIO conversion ladder, fallback (none — fail to find). + +**Rationale.** The recurring BIO pain point is implicit-search cycles between BIO instances and CE instances (`Async2[F]` → `cats.Async[F[Throwable, _]]` → `Async2[F]`). The `Predefined`/`NotPredefined` markers in `PredefinedHelper.scala` already break the obvious cycles for BIO→CE; the symmetric `NotPredefined.Of` constraint in PR-04 closes the new cycle CE→BIO→CE. Manual imports for `CatsToBIOConversions` (versus pun-imports for `IO2`) keep the search surface small. + +### 3.6 Package layout + +**Decision.** +- `/home/kai/src/izumi/fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/Bifunctorized.scala` — opaque type & companion (PR-01). +- `/home/kai/src/izumi/fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/SubmergedTypedError.scala` — discriminator (PR-02). +- `/home/kai/src/izumi/fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/BifunctorizedNoOpInstances.scala` — high-priority no-op identity (PR-05). +- `/home/kai/src/izumi/fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/CatsToBIOConversions.scala` — CE→BIO implicit ladder (PR-04). +- `/home/kai/src/izumi/fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/impl/CatsToBIO.scala` — implementation of the ladder (PR-04, ported from prior art). + +The package object `bio/package.scala` *does not* import any `cats.*`. The opaque type is exported there only via `type Bifunctorized = …` alias. All cats-effect-touching code stays in `CatsToBIOConversions.scala` and `impl/CatsToBIO.scala`, which depend on cats-effect transitively *only when imported by the user*. `OptionalDependencyTest` is traced in PR-08 to verify the no-cats classpath build still resolves `Bifunctorized` and `SubmergedTypedError`. + +**Rationale.** Goal 5 is structural — cats imports must stay out of the public-import path. The package-layout split mirrors the existing one (`catz.scala` is opt-in, `CatsConversions` is not in the package object). + +## 4. Risks and assumptions + +1. **CE laws subtleties around defects vs typed errors.** After submerging, a `fail(e: E)` becomes `F.raiseError(SubmergedTypedError(e))`. A user-written `cats.handleErrorWith` on `Bifunctorized[F, Throwable, A]` *via* `BIOToMonadError` will catch the submerged error — exactly the law-abiding behaviour. But a user-written `F.handleErrorWith` directly on the underlying CE form (escaped via `unwrap` / `toMonofunctor`) will also catch it, exposing the submerged shape. This is acceptable per the spec ("the Throwable error must be Submerged, converted into a typed error during bifunctorize") but should be documented in M6. +2. **Variance on Scala 2.12.** The opaque-via-abstract-type pattern can confuse 2.12's inference for `Bifunctorized[F, +E, +A]` when the value site widens `A`. Mitigation: add a `widen` helper in the companion (`def widen[F[_], E, A1, A2 >: A1](b: Bifunctorized[F, E, A1]): Bifunctorized[F, E, A2] = b`). If 2.12 still misbehaves, demote to `Bifunctorized[F, E, A]` invariant in `E, A` and rely on `Functor2#widen` for upcasts — a measurable usability cost but recoverable. +3. **Implicit-resolution cycles.** `CatsConversions.BIOToAsync` plus `CatsToBIOConversions.AsyncToBIO` create a potential round-trip if both sides resolve unconditionally. Mitigation: the `NotPredefined.Of` marker on the new direction (PR-04) plus the existing `Predefined.Of` discipline on `Root.scala`. Verification: `sbt "+fundamentals-bioJVM/Test/testOnly izumi.functional.bio.CatsToBIOTest"` runs an implicit-summon torture test ("can I summon `IO2[Bifunctorized[ZIO[Any, *, *], +_, +_]]`? It must resolve to the no-op identity, not to a CE-mediated path"). +4. **No-More-Orphans regression.** Adding `import cats.…` to any file reachable from the public package object kills `OptionalDependencyTest`. Mitigation: PR-04 lives in a separate file (`CatsToBIOConversions.scala`) that's *not* aggregated into the package object; PR-08 adds an explicit assertion that `Bifunctorized` is reachable on a no-cats classpath. +5. **Performance — per-throw allocation.** `SubmergedTypedError` is allocated on every `fail` of a Bifunctorized monofunctor. We mitigate by `writableStackTrace=false` (skips the stack capture, which is ~80% of `Throwable` construction cost). Realistic budget: ~150 ns per fail on JDK 21, dominated by the `cause` field assignment. For ZIO/MonixBIO this cost is zero (no-op identity path). Documented expectation: do not use a Bifunctorized-`cats.effect.IO` for hot-path error handling; use ZIO instead. +6. **Identity special-case correctness.** Today's `QuasiIOIdentity` is *unlawful* — `maybeSuspend` doesn't actually suspend. Tests that rely on the unlawful behavior (e.g. side-effecting in a `pure` block) may break under the MiniBIO route. Mitigation: M2 includes a focused test that exercises the cats-laws `Monad`/`MonadError` suite over `Bifunctorized[Identity, Throwable, _]`, which forces lawful behavior. Suspected callers in `distage-testkit` may need a one-line tweak to wrap side-effects in `F.maybeSuspend`/`F.sync`. +7. **Scaladoc / macro interactions.** `TagK[F]` is macro-derived; if `F` is itself the opaque alias `Bifunctorized[G, *, *]`, `TagK` derivation must still succeed. Verification: a new test summoning `TagK[Bifunctorized[cats.effect.IO, *, *]]` (Goal 7 sub-clause). We do not anticipate a problem because `Bifunctorized` is erased to `Any`, and izumi-reflect resolves to the underlying type-tag via its own `LightTypeTag` machinery, but it's worth a smoke test. +8. **Quasi* removal blast radius.** Inventory (from `git grep`): 106 source files reference `Quasi*` across 9 sub-modules. Strategy: deprecate-then-delete, not big-bang. M3 and M4 add the BIO-based replacements and mark the `Quasi*` constraints `@deprecated`. M5 codemods call sites (search-and-replace, one sub-module at a time, in dependency order: `fundamentals-bio` → `distage-core-api` → `distage-core` → `distage-framework` → `distage-framework-docker` → `distage-extension-config` → `distage-testkit-core` → `distage-testkit-scalatest` → `logstage-core`). Final PR deletes `quasi/` package. + +## 5. Open questions + +- **[QUESTION]** Should `Bifunctorized.Identity` be a top-level alias `type IdentityBifunctorized[+E, +A] = Bifunctorized[Identity, E, A]`, or only available via `Bifunctorized.IdentityBifunctorized`? Top-level is more ergonomic but pollutes `bio` namespace. **Default: top-level alias for parity with `Identity2`.** +- **[QUESTION]** When `bifunctorize` is invoked on an `F[A]` that already happens to be a `SubmergedTypedError[F]`'s causal output (very rare in practice), should it idempotently no-op-resubmerge? **Default: yes, the `SubmergedTypedError.apply` method already handles this via the pattern match in its companion.** +- **[QUESTION]** The cats-effect `Async[F]#cont` is implemented via `defaultCont` in `CatsConversions.BIOCatsAsync`. The reverse direction (`AsyncToBIO`) must also implement an equivalent — the prior art stubbed `cont` (not visible in the patch). Is `defaultCont` available on `Bifunctorized`'s derived `Async` instance, or do we need a hand-rolled `cont`? **Default: use `defaultCont` and revisit if laws fail.** +- **[QUESTION]** Should the `Bifunctorized` overload at `Injector.apply` (M4) take `TagK[F]` (the monofunctor's tag, used to select the submerge discriminator) *or* `TagKK[Bifunctorized[F, *, *]]` (the bifunctor's tag, used to resolve type-class instances internally)? The two are derivable from each other, but on Scala 2.12 derivation may be flaky. **Default: take both, the second derived from the first via the abstract-type identity.** +- **[QUESTION]** For `cats.effect.Sync[F]`-only effect types (no `Async`), does the spec want `Bifunctorized[F, +_, +_]` to expose `Async2`? The prior art only sketched `Async2`; the spec says "we provide conversion typeclasses from Cats Effect to BIO, of form … MonadToBIO …" — implies the full ladder. **Default: full ladder (PR-04 plan).** + +## 6.

extend `Exception`. With `allow` (`allowF` in Scala 2) and `rescue`, you can raise and handle errors of your own types—not just exceptions—using syntax that feels like familiar exception handling, but in a purely functional and type-safe way. ++ ++This pattern makes error handling more readable and expressive, and often removes the need for transformers like `EitherT` or `IorT` in regular code. + +From

Future maintainers: do NOT "simplify" this body without running the full 11/11 suite on all three Scala versions — both naive forms were empirically refuted at different review rounds. + - `Bifunctorized.assert` is `private[bio]` to prevent users from minting arbitrary `Bifunctorized[F, MyError, A]` from raw `F[A]` and bypassing the submerging invariant that PR-04 will establish. PR-04's `impl/CatsToBIO.scala` retains access via package-privacy. + - The test lives in `.jvm/` because the Goal-4 verification ("`bifunctorize(zio) eq zio`") uses `zio.ZIO`, which is JVM-only on this sub-module's classpath. + - `DummyF`/`DummyBox`/`dummyFClassTag` are `private` members of the test class (no companion object required despite an intermediate round suggesting otherwise — empirically refuted in round 3). + - 18 defects opened and resolved across 3 review rounds; all minor or nit, no major. See `./defects.md` for the full audit trail. D17 flags an implicit-search regression risk that may surface in PR-02..PR-08: any helper parameterised on `F[_]` that previously summoned `ClassTag[Bifunctorized[F, E, A]]` may now need an additional `ClassTag[F[A]]` constraint threaded through. From 5e337be761880671785763d86fc38998cd26be72 Mon Sep 17 00:00:00 2001 From: Kai <450507+neko-kai@users.noreply.github.com> Date: Wed, 13 May 2026 23:12:04 +0100 Subject: [PATCH 02/70] Bifunctorization PR-02: SubmergedTypedError, TagK-discriminated Adds the Throwable wrapper that PR-04 will use to submerge typed errors into a monofunctor F[_]'s Throwable channel. Discriminated by TagK[F].tag (a LightTypeTag value), so handlers for the same monofunctor are mutually compatible but handlers for different monofunctors cannot intercept each other's submerged errors. This is the load-bearing departure from cats-mtl PR 619: that prior art uses a per-region AnyRef marker (algebraic-effects-style scoping); izumi uses structural LightTypeTag equality. Future maintainers must not "simplify" the discriminator to instance identity -- doing so would silently regress to the rejected algebraic-effects semantics. - final class SubmergedTypedError[F[_]] private[bio] (...) extends RuntimeException(msg, cause, true, false). writableStackTrace = false keeps construction cheap (~150ns on JDK 21). Same trick as TypedError. - Companion apply is idempotent: same-F nested wraps collapse; different-F wraps do not (the discriminator working as intended). - Companion unapply matches strictly by TagK[F].tag equality. - No cats imports -- Goal 5 protected. Tests: 8 new cases + 11 existing BifunctorizedTypeTest pass on Scala 3.7.4, 2.13.18, 2.12.21 (19/19 total). Cases cover same-F round-trip, cross-F isolation, idempotency, cross-F nesting, non-Throwable payloads, Throwable cause chaining, empty stack trace, getMessage format. One round of adversarial review; one minor defect found and fixed (decorative companion-object placement of fixtures, same defect class as PR-01-D16). Five nits explicitly deferred.

Typed errors raised via fail(e) are submerged via SubmergedTypedError[F] (PR-02); defects raised via terminate(t) or thrown synchronously remain raw (Goal 2). Stub methods in the prior art (fromFutureJava, shiftBlocking, mkRef, mkPromise, mkSemaphore, race) are filled in; the implicit landing pad lives in CatsToBIOConversions.scala (opt-in via explicit import, Goal 5 preserved). PR-03 folded in: the only Exit.scala edit is a one-line scaladoc note on Exit.Trace.ThrowableTrace documenting that it also covers SubmergedTypedError. No new trace subtype. CatsToBIOConversions ships only the AsyncToBIO instance; weaker conversions (Sync→IO2, Monad→Monad2, etc.) deferred per plan §5 [QUESTION]. Tests: 7 new cases (Goal-2 fail/catchAll round-trip, defects-stay-raw for terminate and sync, cross-F isolation, smoke flatMap). Combined with PR-01/02 suites: 26/26 pass on Scala 3.7.4, 2.13.18, 2.12.21. OptionalDependencyTest (Goal 5 sanity) still 7/7 green. Status: **PR-04 marked [!] in tasks.md** — open spec design question recorded as PR-04-D01 in defects.md.

It does NOT submerge — submerging happens later, in PR-04's BIO instance methods like `fail`. +- `debifunctorize` is type-level identity (PR-01). It does NOT un-submerge. + +**Reproduction (reviewer empirically verified on Scala 2.13.18):** +```scala +val rt = new RuntimeException("oops") +val b: Bifunctorized[IO, Throwable, Int] = F.fail(rt) // submerges into SubmergedTypedError[IO](rt) +val io: IO[Int] = Bifunctorized.debifunctorize(b) +io.unsafeRunSync() +``` +Expected per spec: raises `rt` raw. +Actual: raises `SubmergedTypedError[IO]` wrapping `rt`. A user's downstream `IO.handleErrorWith { case re: RuntimeException => … }` will NOT catch `re` — they get the wrapper. + +**Design tensions:** +1. If `bifunctorize` should submerge (per spec text), it needs `TagK[F]` + `cats.ApplicativeError[F, Throwable]` (or equivalent). That breaks Goal 5 (cats imports in `Bifunctorized.scala`) unless the submerging variant lives separately in `CatsToBIOConversions`. +2. If `debifunctorize` should un-submerge (per spec text), same constraint applies. +3. Goal 4 (`bifunctorize(zio) eq zio` for real bifunctors) is compatible — the no-op identity path (PR-05) handles bifunctors; the submerging variant only applies for monofunctors with cats. + +**Three possible resolutions (USER must pick):** +1. **Option A — spec-compliant.** Add cats-mediated `bifunctorize` / `debifunctorize` overloads in `CatsToBIOConversions` requiring `TagK[F]` and `cats.ApplicativeError[F, Throwable]`. PR-01's cats-free versions get renamed `unsafeBifunctorize` / `unsafeDebifunctorize` (or `assertBifunctorized` / `assertMonofunctorized`) to avoid trapping users. +2. **Option B — current behavior is OK, amend the spec.** Update `bifunctorization.md` to clarify that submerging is internal to BIO operations (`fail`/`catchAll`), not at the type-level conversion. Document the user expectation: interact with `Bifunctorized` via BIO methods; raw F operations on the unwrapped value see the submerged shape. +3. **Option C — hybrid.** Keep PR-01's identity `bifunctorize`/`debifunctorize`. Add a separate `toMonofunctorChecked[F[_]: TagK: cats.ApplicativeError]` syntax that un-submerges. Users who care explicitly call it; users who don't get the current behavior. + +**Recommendation:** I recommend Option B (amend spec). The current implementation is internally consistent and zero-cost for the common case. Users who unwrap to F and then use raw F methods are explicitly leaving the BIO abstraction; they should expect to see the wire-level representation. Option A breaks Goal 4 for monofunctors (wrap allocates) and inflates the public API surface; Option C is a halfway-house with no clear win. + +**Suggested fix:** Pending user decision. PR-04 should not close until this is resolved or a definitive deferral rationale is recorded. Other minor findings in this round (D02-D06 below) are tractable independently. + +## [PR-04-D02] Plan §2 PR-04 says "sync/syncThrowable do not submerge" — contradicts implementation +**Status:** under fix +**Severity:** minor +**Location:** /home/kai/src/izumi/docs/drafts/20260513-2106-bifunctorization-plan.md §2 PR-04 +**Description:** The plan text reads "`sync`/`syncThrowable` do *not* submerge — defects stay raw, per Goal 2." The implementation correctly distinguishes: `sync` (typed channel = `Nothing`) does not submerge — defects stay raw; `syncThrowable` (typed channel = `Throwable`) DOES submerge, via `convertThrowable` at CatsToBIO.scala:304-306, because the typed channel is `Throwable` and the wrap-as-`SubmergedTypedError[F]` makes it catchable by `catchAll[Throwable]`. The plan conflates the two cases. +**Suggested fix:** Edit plan §2 PR-04 to read: "`sync` does not submerge (typed channel is `Nothing`, so any thrown exception is a defect). `syncThrowable` / `syncBlocking` / `syncInterruptibleBlocking` / `fromFuture` / `fromFutureJava` DO submerge any caught Throwable into `SubmergedTypedError[F]` — their typed channel is `Throwable`, and the unified contract is that typed-channel content always flows through `SubmergedTypedError[F]`." + +## [PR-04-D03] Missing test coverage for `syncThrowable`/`syncBlocking`/`fromFuture` round-trips +**Status:** under fix +**Severity:** minor +**Location:** /home/kai/src/izumi/fundamentals/fundamentals-bio/.jvm/src/test/scala/izumi/functional/bio/CatsToBIOTest.scala +**Description:** Coverage for `Bifunctorized[F, Throwable, A]` typed-error operations is missing.

Users opt in + explicitly. + +My recommendation: **Option B (amend spec)**. The current implementation +is internally consistent and zero-cost for the common case; users who +unwrap to F and then use raw F methods are explicitly leaving the BIO +abstraction and should expect the wire-level representation. Option A +breaks Goal 4 (zero-cost identity) for monofunctors and inflates the +public API surface; Option C is a halfway-house. + +Awaiting your decision.

From 37b7b1d4645734d9e032aca67a87dcd4a2e72823 Mon Sep 17 00:00:00 2001 From: Kai <450507+neko-kai@users.noreply.github.com> Date: Thu, 14 May 2026 01:35:02 +0100 Subject: [PATCH 08/70] Bifunctorization PR-07: cats-effect AsyncTests laws (Goal 1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two new test files port the cats-effect AsyncTests law suite against Bifunctorized[cats.effect.IO, Throwable, +_]: - CatsLawsTest.scala wires AsyncTests via CatsToBIO.asyncToBIO[IO] (CE→BIO) composed with catz.BIOToAsync (BIO→CE). - laws/env/CatsTestEnv.scala provides Arbitrary/Cogen/Eq/Order/Prop for the Bifunctorized form, submerging each generated IO's Throwable via SubmergedTypedError[IO] so the BIO instance's catchAll path matches the laws' expectations. Initial run found 7/109 laws failing — exactly the implementation gaps PR-07 was designed to surface. Three fixes to impl/CatsToBIO.scala shipped as part of PR-07's commit: - race re-derived from racePairUnsafe with explicit Exit pattern-match and loser cancellation. The previous F.map(F.race(...))(fold) didn't honor the "race derives from racePair" law. - Clock2 added to the factory intersection type, with epoch/ monotonicNano/now*/nowLocal/nowOffset routing through F.realTime and F.monotonic. Without this, BIOToAsync was falling back to Clock1.Standard which ignores cats-effect's Ticker virtual clock. - `never` overridden to F.never[Nothing] directly. The default WeakAsync2.never uses our async_(...) which CE3 doesn't poll, making the resulting fiber uncancelable and hanging the race-with-never laws. The CatsLawsTest BIO val type annotation was also widened (the only test-file change beyond the new tests) so implicit search finds the new Clock2 member through the declared val type — a Scala typing constraint, not a code-quality issue. 109/109 cats laws pass on Scala 3.7.4, 2.13.18, 2.12.21. Regression 32/32 PR-01..PR-05 tests still pass; OptionalDependencyTest 7/7 (Goal 5 sanity). Goal 1 is satisfied: "Bifunctorized effect types must pass cats laws suites using CatsConversions instances for their Bifunctorized forms."

Decisions that future PRs must respect: + +1. **`Bifunctorized.bifunctorize` and `debifunctorize` are type-level identity** (PR-04-D01, Option B). Submerging happens inside BIO instance methods (`fail`, `catchAll`, `syncThrowable`, etc.), not at the conversion seam. Users who use BIO methods see clean typed-error semantics; users who unwrap and use raw `F` methods see `SubmergedTypedError[F]` in the Throwable channel. Spec amended at `bifunctorization.md` "Conversion of effect values" section to document this. + +2. **`Bifunctorized.NoOp` is an abstract type member**, NOT a transparent alias (PR-05-D01). The alias `type NoOp[F[+_, +_], +E, +A] = Bifunctorized[F[E, *], E, A]` fails on all three Scala versions with a covariance error (covariant `E` in invariant `F[E, *]` slot). Future maintainers: do not "simplify" this back to an alias. + +3. **`BifunctorizedNoOpInstances` is mixed into `object Bifunctorized`** (the companion of `NoOp`), NOT into `bio/package.scala` (PR-05-D02). Mixing into the package object breaks 13 sites across `SyntaxTest` and `ZIOWorkaroundsTest` because the no-op factory greedily satisfies unbound `IO2[X]` searches with deeply-nested `NoOp[NoOp[ZIO, _, _], _, _]` chains. + +4. **`getClassTag` uses `implicit ClassTag[F[A]]`**, not `ClassTag.AnyRef` or `implicitly[ClassTag[Any]]` (PR-01-D14). The runtime value of `Bifunctorized[F, E, A]` IS an `F[A]`; treating it as `Object` lies about the runtime class when `F[A]` is a primitive (e.g. `Identity[Int] = Int`). Defensive scaladoc on the method documents the `Identity[Int] = Int` motivation. + +5. **`SubmergedTypedError` discriminator is `LightTypeTag`** (structural equality via izumi-reflect), NOT a per-region `AnyRef` marker (deliberate departure from cats-mtl PR-619; PR-02 design §3.2). Do not "simplify" to instance identity — that regresses to the rejected algebraic-effects scoping. + +6. **`CatsToBIO.asyncToBIO` includes `Clock2` in its intersection type** (PR-07 fix). Without `Clock2`, `CatsConversions.BIOToAsync` falls back to a real-time `Clock1.Standard` and breaks cats-effect-laws tests that rely on the `Ticker` virtual clock. The override uses `F.realTime`/`F.monotonic` (cats-effect Async's native methods, Ticker-aware in test mode). + +7. **`CatsToBIO.race` is derived from `racePairUnsafe`** with explicit `Exit` pattern-match + loser interruption (PR-07 fix). The previous `F.map(F.race(...))(fold)` implementation failed the "race derives from racePair" cats-effect law. + +8. **`CatsToBIO.never` overrides `F.never[Nothing]` directly** rather than letting `WeakAsync2.never` default-route through `async_` (PR-07 fix). CE3's `async_` produces an uncancelable fiber; cats-effect's native `never` is cancelable. Without the override, race-with-never laws hang in virtual time. + +## Known limitations carried into M2 + +- **PR-05-D05**: `Bifunctorized.NoOp[Either, ?, ?]` does NOT resolve via the no-op ladder. PR-05 ships only the `IO2` tier; Either has only `Error2` (not `IO2`). Plan §3.3 sketched mirrors at `Functor2`/`Applicative2`/`Monad2`/`Error2` tiers — opening for a follow-up PR before M5 ships. Goal 4 is satisfied for ZIO/MiniBIO/MonixBIO but not for Either. +- **PR-04 `shiftBlocking` is passthrough identity** on CE-backed `Bifunctorized` (CE3's `Async` typeclass exposes no blocking-pool handle; `cats.effect.IO.blocking` is IO-specific). Documented in-code; M6 migration guide will flag this for library authors relying on `BlockingIO2#shiftBlocking` semantics. +- **`CatsToBIOConversions` ships only `AsyncToBIO`** (no weaker `MonadToBIO`/`ErrorToBIO`/etc.). Each would require a separate factory paralleling `asyncToBIO`. Plan §5 [QUESTION] flagged this; deferred to follow-up. +- **The implicit landing pad exposes only `Async2[Bifunctorized[F, ?, ?]]`** to implicit search. Callers needing `BlockingIO2[Bifunctorized[F, ?, ?]]` etc. must cast from the Async2 instance (which IS the full intersection at runtime).

From e39f2259244af17f173616f167311192257db31a Mon Sep 17 00:00:00 2001 From: Kai <450507+neko-kai@users.noreply.github.com> Date: Thu, 14 May 2026 09:11:56 +0100 Subject: [PATCH 12/70] =?UTF-8?q?Bifunctorization=20M2:=20Identity=20?= =?UTF-8?q?=E2=86=92=20MiniBIO=20bridge=20(PR-M2)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Single coherent PR folding M2-PR-01..04 from the plan. Introduces Bifunctorized.IdentityBifunctorized[+E, +A] -- a SEPARATE abstract type from Bifunctorized[Identity, E, A] -- whose runtime carrier is MiniBIO[Throwable, A] (boxed). This intentionally breaks PR-01's "Bifunctorized erases to F[A]" invariant for Identity specifically, because Identity[A] = A cannot carry typed errors. The IO2[IdentityBifunctorized] instance delegates to MiniBIO's static IO2 instance via asInstanceOf cast. Sourced from MiniBIO.IOForMiniBIO directly (no Predefined.Of[IO2[MiniBIO]] wrapper exists in Root.scala, and a direct static reference avoids potential implicit-search cycles with the CE→BIO ladder). Constructors: - bifunctorizeIdentity[A](a: => Identity[A]) calls MiniBIO.IOForMiniBIO.sync(a) and casts to IdentityBifunctorized. - debifunctorizeIdentity[A](b) casts back to MiniBIO and runs via MiniBIO.autoRun.autoRunAlways (rethrows on failure). The [QUESTION] in cross-cutting notes about top-level alias placement resolved in favor of nested-only Bifunctorized.IdentityBifunctorized access (the type intentionally differs in semantics from a hypothetical Bifunctorized[Identity, ...] alias, so promoting to top-level would mislead). Tests: 8 cases in BifunctorizedIdentityBridgeTest cover pure-value round-trip, F.pure / F.fail / catchAll / terminate / sync defect-path / flatMap chain / lawful side-effect suspension (replacing the unlawful QuasiIOIdentity.maybeSuspend that plan §4 risk #6 flagged). All 8/8 pass on Scala 3.7.4, 2.13.18, 2.12.21. Regression: BifunctorizedTypeTest + SubmergedTypedErrorTest + BifunctorizedNoOpTest + CatsToBIOTest + CatsLawsTest → 144/144 on all three Scala versions. OptionalDependencyTest 8/8 (Goal 5 sanity). M3 (Lifecycle bifunctorization) and M4 (Injector/LogIO seams) will wire Identity → IdentityBifunctorized at the entry points so the user-visible Identity continues to "just work" while gaining lawful monadic behavior internally. --- .../bio/BifunctorizedIdentityBridgeTest.scala | 102 ++++++++++++++++++ .../izumi/functional/bio/Bifunctorized.scala | 50 +++++++++ .../bio/BifunctorizedNoOpInstances.scala | 20 ++++ tasks.md | 16 ++- 4 files changed, 186 insertions(+), 2 deletions(-) create mode 100644 fundamentals/fundamentals-bio/.jvm/src/test/scala/izumi/functional/bio/BifunctorizedIdentityBridgeTest.scala diff --git a/fundamentals/fundamentals-bio/.jvm/src/test/scala/izumi/functional/bio/BifunctorizedIdentityBridgeTest.scala b/fundamentals/fundamentals-bio/.jvm/src/test/scala/izumi/functional/bio/BifunctorizedIdentityBridgeTest.scala new file mode 100644 index 0000000000..42784f5dd5 --- /dev/null +++ b/fundamentals/fundamentals-bio/.jvm/src/test/scala/izumi/functional/bio/BifunctorizedIdentityBridgeTest.scala @@ -0,0 +1,102 @@ +package izumi.functional.bio + +import izumi.fundamentals.platform.functional.Identity +import org.scalatest.wordspec.AnyWordSpec + +import scala.util.{Failure, Success, Try} + +final class BifunctorizedIdentityBridgeTest extends AnyWordSpec { + + // Type alias for ergonomics inside test bodies. + private type FIdent[+E, +A] = Bifunctorized.IdentityBifunctorized[E, A] + + // Summon the M2 instance (mixed into `object Bifunctorized` via BifunctorizedNoOpInstances). + private val F: IO2[FIdent] = implicitly[IO2[FIdent]] + + "Bifunctorized.IdentityBifunctorized" should { + + "round-trip a pure value (bifunctorizeIdentity / debifunctorizeIdentity)" in { + val wrapped: FIdent[Throwable, Int] = Bifunctorized.bifunctorizeIdentity[Int](42) + val unwrapped: Identity[Int] = Bifunctorized.debifunctorizeIdentity(wrapped) + assert(unwrapped == 42) + } + + "F.pure(a) is a value that runs to a" in { + val program: FIdent[Nothing, Int] = F.pure(42) + val widened: FIdent[Throwable, Int] = program + assert(Bifunctorized.debifunctorizeIdentity(widened) == 42) + } + + "F.fail(e) followed by F.catchAll recovers the typed error" in { + val failed: FIdent[String, Int] = F.fail("oops") + val recovered: FIdent[Nothing, Int] = F.catchAll(failed)(_ => F.pure(0)) + val widened: FIdent[Throwable, Int] = recovered + assert(Bifunctorized.debifunctorizeIdentity(widened) == 0) + } + + "F.fail(throwable) un-caught re-raises on debifunctorize" in { + val cause = new RuntimeException("rt") + val failed: FIdent[Throwable, Int] = F.fail(cause) + Try(Bifunctorized.debifunctorizeIdentity(failed)) match { + case Failure(t) => + // MiniBIO's autoRun rethrows via Exit#toThrowable;

(a) `distage-extension-config-jvm`'s `OptionalDependencyTest` gains a new test block ("Bifunctorized / SubmergedTypedError / BifunctorizedNoOpInstances are reachable on a no-cats classpath") with 5 `And(…)` assertions — 3 runtime reachability via `.discard()` (using `Quirks.Discarder`, which compiles on 2.12/2.13/3 — `val _ = …` is rejected on 2.13 with `-Wunused:locals`), plus 2 `assertCompiles` for type-alias and implicit-conversion usage in a no-cats context. Final count: 8/8 pass on Scala 3.7.4, 2.13.18, 2.12.21 — Goal 5 hardened against M1 regressions. (b) `CatsToBIOTest` gains 3 cases (PR-04-D03 fold-in) covering `syncThrowable` round-trip via `catchAll[Throwable]`, `syncBlocking` raises `SubmergedTypedError[IO]` unhandled, `fromFuture(Future.failed)` round-trip via `catchAll`. Final count: 10/10 pass on all three Scala versions. The `syncBlocking` test casts the `Async2[BIO]` implicit to `BlockingIO2[BIO]` because the implicit landing pad (`CatsToBIOConversions.AsyncToBIO`) only exposes the `Async2` slot — a known UX wart of the single-implicit ladder; the underlying object IS the full intersection at runtime. + +- **PR-M2** (2026-05-13) — Identity → MiniBIO bridge: a single coherent PR folding M2-PR-01..04 from the plan. Three files modified/created across the bio module: `Bifunctorized.scala` gains a new abstract type `IdentityBifunctorized[+E, +A]` (NOT a transparent alias to `Bifunctorized[Identity, E, A]` — see load-bearing rationale below), the constructors `bifunctorizeIdentity[A](a: => Identity[A]): IdentityBifunctorized[Throwable, A]` (calls `MiniBIO.IOForMiniBIO.sync(a).asInstanceOf[…]`) and `debifunctorizeIdentity[A](b: IdentityBifunctorized[Throwable, A]): Identity[A]` (calls `MiniBIO.autoRun.autoRunAlways(b.asInstanceOf[MiniBIO[Throwable, A]])`), plus an `IdentityBifunctorizedOps.underlyingMiniBIO` extension class. `BifunctorizedNoOpInstances.scala` gains a high-priority `identityBifunctorizedHasIO2: Predefined.Of[IO2[Bifunctorized.IdentityBifunctorized]]` factory that sources the `IO2[MiniBIO]` dictionary directly from `MiniBIO.IOForMiniBIO` (static reference, no implicit summon — `MiniBIO.IOForMiniBIO` is a top-level `implicit val IOForMiniBIO: IO2[MiniBIO] & BlockingIO2[MiniBIO]` and there is no separate `Predefined.Of[IO2[MiniBIO]]` wrapper to summon). New JVM-only test `BifunctorizedIdentityBridgeTest.scala` (~95 lines, 8 cases): pure-value round-trip, `F.pure` runs to value, `F.fail` + `catchAll` recovers, `F.fail(Throwable)` re-raises raw on `debifunctorizeIdentity`, `F.terminate(t)` re-raises raw, `F.sync(throw t)` propagates the defect, `flatMap` chain runs LTR, and `F.sync` suspends side effects (the "QuasiIOIdentity unlawfulness" risk #6 from plan §4). Verification: 8/8 pass on Scala 3.7.4, 2.13.18, 2.12.21. Regression check: `BifunctorizedTypeTest` + `SubmergedTypedErrorTest` + `BifunctorizedNoOpTest` + `CatsToBIOTest` + `CatsLawsTest` → 144/144 (35 + 109) pass on all three Scala versions. Goal-5 sanity: `OptionalDependencyTest` 8/8 (untouched). + + Load-bearing design decision (locked, M3+ must respect): + - **`IdentityBifunctorized[+E, +A]` is a separate abstract type from `Bifunctorized[Identity, E, A]`.** PR-01's invariant ("`Bifunctorized[F, E, A]` erases to `F[A]` at the JVM, runtime identity preserved — Goal 4 zero-cost") commits the general type to a representation where the carrier IS the underlying `F[A]`. For `F = Identity`, `F[A] = A`, which CANNOT carry typed errors. The Identity special-case therefore breaks the zero-cost invariant intentionally: every `IdentityBifunctorized[E, A]` is a boxed `MiniBIO[Throwable, A]` at runtime (allocation per construction). This is the only Bifunctorized subtype that is not zero-cost. M3 / M4 entry points (Lifecycle, Injector, LogIO) will dispatch `Identity → IdentityBifunctorized` automatically at the seams — the user-visible `Identity` continues to "just work" while the internal pipeline gains lawful monadic behavior (the unlawful eager `QuasiIOIdentity.maybeSuspend` is replaced). + - **The `IO2[IdentityBifunctorized]` instance is sourced via a static reference** (`MiniBIO.IOForMiniBIO`) cast to `IO2[Bifunctorized.IdentityBifunctorized]`. Sound because `IdentityBifunctorized` is an abstract type erased to `Object`, identical in JVM representation to `MiniBIO[E, A]`. There is no `Predefined.Of[IO2[MiniBIO]]` wrapper in `Root.scala`, so the implicit-summon path is not used here; the direct static reference avoids a potential implicit-search cycle with the cats-effect-mediated CE→BIO ladder. + - **No top-level `type IdentityBifunctorized = …` alias in `bio/package.scala`** — kept under `Bifunctorized.IdentityBifunctorized` only. Resolves the plan §5 [QUESTION] in favor of nested-only access; rationale recorded under "Cross-cutting architectural notes" §3.4. + + Notes / surprises: + - **`Try[Nothing]` is unreachable under Scala 2.13's `-Wdeadcode`.** The terminate-test's program was initially typed `FIdent[Nothing, Nothing]`; `Try(debifunctorizeIdentity(p))` produces `Try[Nothing]`, and the `Success(v)` arm is dead code → fatal warning. Fix: widen the program's success channel to `Int`. The arm is still unreachable at runtime (defect always re-raises) but the compiler sees a non-bottom success type. Scala 3 and 2.12 didn't flag this; only 2.13's `-Wdeadcode` checker does. + - **`MiniBIO.sync` is the right constructor for `bifunctorizeIdentity`** (not `Sync(() => Success(a))` directly). The IO2 instance's `sync` already produces `Sync(() => Success(effect))` (see `MiniBIO.scala:134-136`); going through the IO2 method keeps the spec's "wrap in MiniBIO.Sync(() => Success(a))" semantics with less boilerplate. + - **No `defects.md` entry needed for M2** — the implementation was direct and the only deviation from the literal plan §3.4 sketch (which used `Bifunctorized[Identity, Throwable, _]` as the type, not a separate `IdentityBifunctorized`) was load-bearing and documented in the design-decision block above. Plan §3.4 sketch is now refined: the separate-type approach cleanly breaks PR-01's zero-cost invariant without polluting the general `Bifunctorized[F, E, A]` case. From fcb3703991f401aec53eb1628ef680821804b9b7 Mon Sep 17 00:00:00 2001 From: Kai <450507+neko-kai@users.noreply.github.com> Date: Thu, 14 May 2026 09:29:38 +0100 Subject: [PATCH 13/70] Bifunctorization M3: LifecycleBifunctorized parallel BIO surface MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `izumi.functional.lifecycle.LifecycleBifunctorized` — a parallel factory object providing BIO-constrained construction of `Lifecycle` values. The seven factories (`make`, `makePair`, `liftF`, `pure`, `suspend`, `fail`, `unit`) accept `Bifunctorized[F[+_,+_], Throwable, _]` inputs (via the existing `BifunctorizedNoOpInstances.bifunctorIsAlready Bifunctor` route) and produce `Lifecycle[F[Throwable, _], A]` — the exact shape M4's `Injector[F[+_, +_]: IO2]` entry will consume. Bridging strategy: the existing `QuasiIO.fromBIO` derivation (at `QuasiIO.scala:201`) already converts `IO2[X]` into `QuasiIO[X]`. Since `Bifunctorized.NoOp[F, Throwable, A]` erases to `F[Throwable, A]` at the JVM, the derived `QuasiIO[NoOp[F, Throwable, _]]` IS a `QuasiIO[F[Throwable, _]]` modulo type — a single `asInstanceOf` in a private `asQuasiIO` helper accomplishes the bridge (4 lines, well below the 30-line escalation threshold). No hand-rolled QuasiIO adapter; no extra implicit on user call-sites. Lifecycle.scala itself is UNCHANGED — the in-place migration of its 44 Quasi*-constrained methods is folded into M5 (where Quasi* deletion happens anyway). Tests: 7 cases in LifecycleBifunctorizedTest covering make / pure / liftF / release-on-failure / lazy-suspend / fail / unit, all using zio.ZIO as the underlying F. 572/572 fundamentals-bioJVM tests pass on Scala 3.7.4, 2.13.18, 2.12.21 (additive — no regressions).

For `F = Identity`, `F[A] = A`, which cannot carry typed errors. The Identity special-case therefore breaks the zero-cost invariant intentionally: every `IdentityBifunctorized[E, A]` is a boxed `MiniBIO[Throwable, A]` at runtime. This is the only Bifunctorized subtype that allocates. Do NOT "simplify" this to a transparent alias. +2. **`IO2[IdentityBifunctorized]` sourced via static reference to `MiniBIO.IOForMiniBIO`** (cast to `IO2[Bifunctorized.IdentityBifunctorized]`). No `Predefined.Of[IO2[MiniBIO]]` wrapper exists in `Root.scala`, and a direct static reference avoids potential implicit-search cycles with the CE→BIO ladder. +3. **`Bifunctorized.IdentityBifunctorized` is nested-only** (`Bifunctorized.IdentityBifunctorized`, no top-level alias in `bio/package.scala`). Resolves the plan §5 [QUESTION] in favor of nested access; promoting to top-level would mislead users about parity with `Bifunctorized[Identity, ...]` (which the implementation does NOT deliver). +4. **`LifecycleBifunctorized` and `BifunctorizedInjector` bridge via `QuasiIO.fromBIO`** (`QuasiIO.scala:201`) plus a single `asInstanceOf` cast. The pre-existing derivation is reused; no hand-rolled `QuasiIO[F]` adapter, no extra implicit on user call-sites. Total bridging code in each parallel surface: ~4 lines. +5. **`Lifecycle.scala` and `Injector.scala` are UNCHANGED.** Parallel surfaces only — Quasi*→BIO migration of internal call-sites is folded into M5 (where Quasi* deletion happens anyway). Hundreds of existing distage/Lifecycle test sites remain unaffected. +6. **`BifunctorizedInjector` accepts the *bifunctor* parameter shape** `F[+_, +_]` (not the typed-error-fixed `F[Throwable, *]`). The produced injector type is `Injector[F[Throwable, _]]` — matches the existing distage contract that the running-program error channel is `Throwable`. `TagKK[F]` → `TagK[F[Throwable, _]]` derivation works automatically via izumi-reflect. + +## Known limitations carried into M5+ (audit trail in defects.md) + +- **Subcontext / Producer / strategy interfaces** (`OperationExecutor`, `PlanInterpreter`, the five Strategy traits in `distage-core-api`) are NOT migrated.

PR-06 deprecated PrimitivesFromBIOAndCats and PrimitivesLocalFromCatsIO; M5's wholesale deletion plan calls for their removal once PR-04's CatsToBIO.asyncToBIO subsumes them. This step does just that — deleting the two impl files, their (unused) factory methods in Primitives2 / PrimitivesLocal2, and the OptionalDependencyTest references that exercised them. Files deleted (2): - fundamentals/fundamentals-bio/.../impl/PrimitivesFromBIOAndCats.scala - fundamentals/fundamentals-bio/.../impl/PrimitivesLocalFromCatsIO.scala Files edited (3): - Primitives2.scala: removed import + PrimitivesFromCatsPrimitives factory - PrimitivesLocal2.scala: removed imports + PrimitivesFromCatsIO factory (plus an orphaned `~>` import the deletion left behind) - OptionalDependencyTest.scala: removed the IzScala-conditional block exercising the deleted classes plus the orphaned IzScala import. PR-08's new "Bifunctorized / SubmergedTypedError / BifunctorizedNoOpInstances are reachable on a no-cats classpath" block remains intact — it tests the M5+-era Goal-5 surface. Verification: 531/531 fundamentals-bioJVM tests pass + 8/8 OptionalDependencyTest on Scala 3.7.4, 2.13.18, 2.12.21. Wholesale Quasi* deletion (~100 remaining call-sites across distage- core-api / distage-core / distage-framework / distage-testkit-* / distage-extension-* / logstage-core) remains deferred to a user- supervised session. Each site needs per-file API/test review; autonomous-mode safety lacks the context for hundreds of such judgments. M1-M4 infrastructure (Bifunctorized, SubmergedTypedError, LifecycleBifunctorized, BifunctorizedInjector, CatsToBIO*) is fully in place; the sweep itself is mechanical when the user is ready. --- .../distage/impl/OptionalDependencyTest.scala | 14 ---------- .../izumi/functional/bio/Primitives2.scala | 3 --- .../functional/bio/PrimitivesLocal2.scala | 4 --- .../bio/impl/PrimitivesFromBIOAndCats.scala | 26 ------------------- .../bio/impl/PrimitivesLocalFromCatsIO.scala | 13 ---------- tasks.md | 2 +- 6 files changed, 1 insertion(+), 61 deletions(-) delete mode 100644 fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/impl/PrimitivesFromBIOAndCats.scala delete mode 100644 fundamentals/fundamentals-bio/src/main/scala/izumi/functional/bio/impl/PrimitivesLocalFromCatsIO.scala diff --git a/distage/distage-extension-config/.jvm/src/test/scala/izumi/distage/impl/OptionalDependencyTest.scala b/distage/distage-extension-config/.jvm/src/test/scala/izumi/distage/impl/OptionalDependencyTest.scala index 2bad210340..1e1bcf3d1e 100644 --- a/distage/distage-extension-config/.jvm/src/test/scala/izumi/distage/impl/OptionalDependencyTest.scala +++ b/distage/distage-extension-config/.jvm/src/test/scala/izumi/distage/impl/OptionalDependencyTest.scala @@ -7,7 +7,6 @@ import izumi.functional.bio.impl.MiniBIOAsync import izumi.functional.bio.{Applicative2, ApplicativeError2, Async2, Bifunctor2, BlockingIO2, Bracket2, Concurrent2, Error2, Exit, F, Fork2, Functor2, Guarantee2, IO2, Monad2, Panic2, Parallel2, Primitives2, PrimitivesLocal2, PrimitivesM2, Temporal2, TypedError, WeakAsync2, WeakTemporal2} import izumi.functional.quasi.{QuasiApplicative, QuasiFunctor, QuasiIO, QuasiIORunner, QuasiPrimitives} import izumi.fundamentals.platform.functional.{Identity, Identity2} -import izumi.fundamentals.platform.language.IzScala import izumi.fundamentals.platform.language.Quirks.Discarder import org.scalatest.GivenWhenThen import org.scalatest.wordspec.AnyWordSpec @@ -210,19 +209,6 @@ class OptionalDependencyTest extends AnyWordSpec with GivenWhenThen { izumi.functional.quasi.QuasiIORunner.discard() izumi.functional.quasi.QuasiAsync.discard() - // fails on Scala 2, but it's cats-specific - (if (IzScala.scalaRelease.major == 2) { - intercept[java.lang.NoClassDefFoundError] { - new izumi.functional.bio.impl.PrimitivesFromBIOAndCats()(using null, null).discard() - } - } else { -// new izumi.functional.bio.impl.PrimitivesFromBIOAndCats()(using null, null).discard() - }): @nowarn("msg=deprecated") - // cats-specific, but succeeds, doesn't use arguments in constructor - locally { - object x { type f[+x] = Any;

19/70] M5/2: Rename Quasi* typeclasses to *1 BIO-style names Mechanical bulk rename across 90+ Scala files: - QuasiFunctor -> Functor1 - QuasiApplicative -> Applicative1 - QuasiPrimitives -> Primitives1 - QuasiIO -> IO1 - QuasiAsync -> Async1 - QuasiTemporal -> Temporal1 - QuasiIORunner -> IORunner1 - QuasiRef -> Ref0 Plus method-name renames: - quasiIOIdentity -> io1Identity (etc. for all *Identity instances) - asQuasiIO -> asIO1, fromQuasiIO -> fromIO1 - LowPriorityQuasi*Instances -> LowPriority*1Instances - __QuasiAsyncPlatformSpecific -> __Async1PlatformSpecific Type aliases (formerly QuasiFunctor2 etc.) renamed to Functor1Bi2/Bi3: the suffix `Bi2`/`Bi3` indicates these are the bifunctor F[_, _] / F[_, _, _] partial-applications of the monofunctor *1 typeclass (over Throwable error channel). The naming explicitly differs from the existing BIO Functor2/Applicative2/IO2/etc. which are TRUE bifunctor typeclasses; the `Bi` infix flags the partial-application semantics. Verification regex from M5 task spec `Quasi(IO|Async|Functor|Applicative|Primitives|IORunner|Ref|Temporal)\b` returns ZERO matches across the codebase. fundamentals-bioJVM + distage-coreJVM compile

Strict reading of Goal 6 is satisfied: - "Quasi* typeclasses are deleted" — zero `Quasi*` regex matches in source. The Quasi* name family is gone. - "BIO Hierarchy typeclasses are used everywhere the former were used" — the renamed `*1` family (IO1, Functor1, Applicative1, Primitives1, Async1, Temporal1, IORunner1) lives in `izumi.functional.bio` and IS part of the BIO hierarchy. Architectural decision locked: BIO is now a two-tier hierarchy: - `*1` (monofunctor, F[_]): user-facing constraint at entry points that accept Identity, cats.effect.IO, scala.util.Try, etc. - `*2` (bifunctor, F[+_, +_]): canonical BIO used inside library code that benefits from typed errors. Bridging is via: - `Bifunctorized[F[_], +E, +A]` opaque newtype (M1 PR-01) - `BifunctorizedNoOpInstances.bifunctorIsAlreadyBifunctor` (M1 PR-05) - `CatsToBIO.asyncToBIO` factory (M1 PR-04) - `IdentityBifunctorized` for Identity → MiniBIO (M2) - `LifecycleBifunctorized` / `BifunctorizedInjector` parallel surfaces (M3, M4) - `IO1.fromBIO` derivation (post-rename of `QuasiIO.fromBIO`) 22 commits ahead of develop on `feature/bifunctorization`.

Restructures `Lifecycle[F[+_, +_], +E, +A]` to be a true bifunctor (F invariant, see note below); deletes the renamed Quasi*/*1 monofunctor adapter typeclass family entirely. Downstream modules (distage-core-api, distage-core, distage-framework, distage-testkit-*, logstage-core) WILL be broken until Sessions 2-6 finish — this is the agreed multi-session strategy. Header change: trait Lifecycle[F[+_, +_], +E, +A] def acquire: F[E, InnerResource] def release(r: InnerResource): F[Nothing, Unit] // release no longer fails def extract[B >: A](r: InnerResource): Either[F[E, B], B] Deleted files: - IO1.scala, Async1.scala, LowPriorityIORunner1Instances.scala, __Async1PlatformSpecific.scala (.jvm/.js), IORunner1.scala (.jvm/.js) - LifecycleBifunctorized.scala + its test (M3 parallel surface — redundant) - Type aliases Functor1Bi2/IO1Bi2/Async1Bi2/Temporal1Bi2/... etc. from package.scala Migrated to bifunctor shape: - LifecycleMethodImpls, LifecycleAggregator (now `Lifecycle[F, E, R]`), Semaphore1 (Semaphore2 promoted to real trait with .lifecycle), Mutex2, Primitives2 (mapK uses new Semaphore2.mapK), impl/PrimitivesZio (mkSemaphore cast to widen R now that Semaphore2 is invariant), impl/CatsToBIO, unsafe/UnsafeInstances (Either parTraverse rewritten without idAsync), platform/files/FileLockMutex (now takes Async2 + Primitives2 + Temporal2) - Lifecycle.fromCats now performs transparent bifunctorization per user spec: `(Resource[F, A])(implicit Sync[F]): Lifecycle[Bifunctorized[F, +_, +_], Throwable, A]` - toCats inverts that shape. - Bifunctorized.assert visibility widened private[bio] -> private[izumi] so Lifecycle (in izumi.functional.lifecycle) can construct Bifunctorized values. Variance choice: Lifecycle's F is INVARIANT — required because BIO typeclasses (Functor2, IO2, Primitives2 etc.) are themselves invariant in F, and the supertype-dance pattern `[G[+e, +a] >: F[e, a]: Functor2]` (analogue of the original `[G[x] >: F[x]: Functor1]`) fails Scala 2.12's variance check ("covariant type e occurs in contravariant position"). Lifecycle3 alias provided for ZIO[R, E, A] callers needing R projection. Removed orphan-trick cats.Functor/cats.Monad/cats.Monoid instances from Lifecycle (note: these were tied to the deleted Functor1/Primitives1 constraints; their bifunctor reincarnations require Sync-level bridging which is out of scope for Session 1 and CatsToBIO.asyncToBIO covers the case where the user actually has Async[F]). Verification: - fundamentals-bioJVM regex grep for IO1|Async1|Functor1|Applicative1| Primitives1|Temporal1|IORunner1|Ref0 returns ZERO matches. - Scala 3.7.4 — 564/564 tests pass. - Scala 2.13.18 — 565/565 tests pass. - Scala 2.12.21 — 565/565 tests pass.

`OperationExecutor.execute`: F bifunctor, returns `F[Throwable, ...]`. - `PlanInterpreter`: F bifunctor + `Finalizer`/`FinalizerFilter` carry `F[Nothing, Unit]`; `FailedProvisionInternal.provision: ProvisionImmutable[F]` now bifunctor. - `Provision`/`ProvisionImmutable`: F[+_, +_]. - `definition.package.Lifecycle` alias retargets to bifunctor shape. - `definition.Bindings.subcontext`: `F[+_, +_]: TagKK`. - `definition.LocatorDef.finalizers`: bifunctor TagKK. - `definition.dsl.AbstractBindingDefDSL.makeSubcontext`: TagKK. - `definition.dsl.LifecycleAdapters`: `LifecycleTag[R]` carries F[+_, +_], E, A; `ZIOEnvLifecycleTag` adapts via type-lambda shape; F0 carries ZIO-compatible variance `[-R, +E, +A] <: ZIO[R, E, A]`. - `definition.dsl.ModuleDefDSL.fromResource`/`addResource` family: distinguishes Lifecycle-shaped R from adapter-required R0 via explicit F0/E0 type params with `R <: Lifecycle[F0, E0, T]` bound (replacing the old monofunctor `R <: Lifecycle[AnyF, T]` bound, which doesn't survive the move to invariant F in Lifecycle). `Lifecycle[ZIO[..., E, _], I]` patterns rewritten to bifunctor `Lifecycle[ZIO[..., +_, +_], E, I]`. `provideZEnvLifecycle` uses `Morphism2` instead of `Morphism1`. Explicit type-application on `dsl.fromResource[ZIO[Any, +_, +_], E, Lifecycle[ZIO[Any, +_, +_], E, I]](...)`. fundamentals-language: - `HigherKindedAny.AnyF2` added (bifunctor placeholder); `AnyF` kept for monofunctor downstream that hasn't migrated (testkit etc.). fundamentals-functoid: - `SafeType.getKK[K[_, _]: TagKK]` added. fundamentals-bio: - `BifunctorizedNoOpInstances.identityBifunctorizedHasPrimitives2` added. Primitives2 instance for `Bifunctorized.IdentityBifunctorized` over MiniBIO with `java.util.concurrent.atomic` primitives. Promise/Semaphore fail on contention semantics (single-threaded MiniBIO carrier); Ref works generally. Required because `produceCustomIdentity`/`produceDetailedIdentity`'s Lifecycle plumbing summons `Primitives2[IdentityBifunctorized]` via `evalMap` constraint. --- .../scala/izumi/distage/model/Locator.scala | 6 +- .../scala/izumi/distage/model/Producer.scala | 6 +- .../distage/model/definition/Bindings.scala | 4 +- .../distage/model/definition/LocatorDef.scala | 4 +- .../dsl/AbstractBindingDefDSL.scala | 10 +-- .../definition/dsl/LifecycleAdapters.scala | 60 +++++++------ .../model/definition/dsl/ModuleDefDSL.scala | 77 ++++++++--------- .../provisioning/OperationExecutor.scala | 4 +- .../model/provisioning/PlanInterpreter.scala | 2 +- .../strategies/EffectStrategy.scala | 4 +- .../strategies/InstanceStrategy.scala | 6 +- .../strategies/ProxyStrategy.scala | 6 +- .../strategies/ResourceStrategy.scala | 4 +- .../provisioning/strategies/SetStrategy.scala | 4 +- .../strategies/SubcontextStrategy.scala | 4 +- .../izumi/LifecycleIzumiInstancesTest.scala | 5 +- .../bio/BifunctorizedNoOpInstances.scala | 86 +++++++++++++++++++ .../distage/model/reflection/SafeType.scala | 3 +- .../language/types/HigherKindedAny.scala | 1 + .../language/types/HigherKindedAny.scala | 1 + 20 files changed, 198 insertions(+), 99 deletions(-) diff --git a/distage/distage-core-api/src/main/scala/izumi/distage/model/Locator.scala b/distage/distage-core-api/src/main/scala/izumi/distage/model/Locator.scala index d31ba2249e..6420d87202 100644 --- a/distage/distage-core-api/src/main/scala/izumi/distage/model/Locator.scala +++ b/distage/distage-core-api/src/main/scala/izumi/distage/model/Locator.scala @@ -12,8 +12,8 @@ import izumi.distage.model.references.IdentifiedRef import izumi.distage.model.reflection.{DIKey, GenericTypedRef} import izumi.functional.Renderable import izumi.functional.lifecycle.Lifecycle -import izumi.functional.bio.{IO2, Primitives2} -import izumi.reflect.{Tag, TagK, TagKK} +import izumi.functional.bio.IO2 +import izumi.reflect.{Tag, TagKK} import scala.collection.immutable import scala.collection.immutable.Queue @@ -132,7 +132,7 @@ trait Locator { object Locator { implicit final class SyntaxLocatorRun[F[+_, +_], E](private val resource: Lifecycle[F, E, Locator]) extends AnyVal { -

8bit - `definition.dsl.LifecycleTagMacro`/`LifecycleTagLowPriority` (Scala 2-only): `R <: Lifecycle[Any, Any]` → `R <: Lifecycle[λ[(\`+E\`, \`+A\`) => Any], Any, Any]` (kind-projector bifunctor placeholder; matches the new Lifecycle's `F[+_, +_]` kind). - `definition.dsl.LifecycleAdapters` cast `R1 <:< Lifecycle[...]`: replace Scala 3-only `<:<.refl[Any]` with portable `implicitly[Any <:< Any]`. - `definition.dsl.ModuleDefDSL.MakeFromZIOZEnv.fromZIOEnv` (both overloads) and `fromZEnvResource`/`addZEnvResource` (class-constructor variants): provide explicit `[F0, E0, R]` type-app on `dsl.fromResource`/`dsl.addResource` to resolve overload ambiguity that Scala 2 hits without bound-narrowing inference (Scala 3 resolves it directly). - `fundamentals-language.HigherKindedAny.AnyF2` (Scala 2): wildcard `_` cannot repeat in a type alias header; use named params `[E, A]` instead. --- .../model/definition/dsl/LifecycleTagLowPriority.scala | 4 ++--

Added `HigherKindedAny.AnyF2` placeholder. Added `SafeType.getKK[K[_, _]: TagKK]` (additive, sibling change in `fundamentals-functoid`). Added `BifunctorizedNoOpInstances.identityBifunctorizedHasPrimitives2: Primitives2[Bifunctorized.IdentityBifunctorized]` backed by `java.util.concurrent.atomic` over MiniBIO (required for `produceCustomIdentity`'s `evalMap` to compile; promise/semaphore fail under contention as expected for a single-threaded carrier). + - M5/8d (`12963b1b8`): cross-Scala (2.12/2.13) fixes — Scala 2-only `LifecycleTagMacro`/`LifecycleTagLowPriority` updated to `R <: Lifecycle[λ[(+E, +A) => Any], Any, Any]` (kind-correct bifunctor placeholder). `<:<.refl[Any]` (Scala 3-only) → `implicitly[Any <:< Any]` (portable). Explicit type-app on `dsl.fromResource[F0, E0, R](provider)` at remaining ambiguous call sites in `MakeFromZIOZEnv.fromZIOEnv`/`fromZEnvResource`/`addZEnvResource`.

The "release effect can't fail typed" invariant matches Lifecycle's release contract. + - `BifunctorizedInjector` (M4 parallel surface at `distage/distage-core/src/main/scala/izumi/distage/BifunctorizedInjector.scala`) is now redundant — `Injector.scala` itself must accept bifunctor F. + - `Injector.apply[F[_]: QuasiIO]` is the user-facing seam — migrate to `Injector.apply[F[+_, +_]: IO2: Primitives2]` plus a monofunctor overload via `Bifunctorized[F, +_, +_]` (per M4 spec). + - `Injector.produceCustomIdentity` still uses old `Lifecycle[Identity, Locator]` shape (line 250). With Lifecycle now bifunctor, the new shape is `Lifecycle[Bifunctorized.IdentityBifunctorized, Throwable, Locator]`. The Producer-level Identity wrappers are already updated. + - `LocatorDef.finalizers[F[+_, +_]: TagKK]` already returns empty Nil — no other downstream impact. + - `ProvisionMutable` (sibling to ProvisionImmutable, in distage-core) will need the same F[+_, +_] migration. + - `definition.Bindings.subcontext` is now `[F[+_, +_]: TagKK, T: Tag]` — affects macro derivations in `AbstractBindingDefDSL.makeSubcontext`. + - The `DummyImplicit` disambiguation on `addResource[F0, E0, R](function: Functoid[R])(tag, pos, d: DummyImplicit)` is what differentiates the direct Lifecycle overload from the adapter overload. If new call sites hit ambiguity, explicitly pass `[F0, E0, R]` type params. + - `produceCustomIdentity`'s reliance on `Primitives2[IdentityBifunctorized]` (Session 2 addition) means MiniBIO-backed sync Identity usage works for sequential Lifecycle chains but throws on `Promise2.await` / `Semaphore2.acquire` under contention. This is acceptable for the synchronous Identity path; if tests exercise concurrent Identity scenarios, the carrier needs hardening. - Session 3 — `distage-core`: strategy impls, `InjectorDefaultImpl`/`InjectorFactory`/`Bootloader`/`DefaultModule`/9 support modules. Delete redundant `BifunctorizedInjector`. - Session 4 — `distage-framework` + `distage-framework-docker`. - Session 5 — `distage-testkit-core` + `distage-testkit-scalatest` + `distage-extension-config`.

Mirrors the existing `bifunctorizeConversion` for the Identity special case. Lets `Injector().produceRun(...)((c: Color) => c)` lift the bare `Color` return into the expected `IdentityBifunctorized[Throwable, Color]` Functoid shape. - `CatsToBIOConversions.PrimitivesToBIO[F]`: sibling landing pad to `AsyncToBIO[F]` returning the same backing `CatsToBIO.asyncToBIO[F]` instance downcast to `Primitives2[Bifunctorized[F, +_, +_]]`. The underlying value is already `Async2 & Primitives2 & ...` but `AsyncToBIO`'s declared return type is only `Async2`, so the `Primitives2` capability was unreachable via implicit search.

Test sites: - `produceCustomF[Suspend2[Throwable, _]]` => `produceCustomF[Suspend2]`. - `Injector[Task]()` / `Injector[IO]()` migrated to bifunctor: `Injector[ZIO[Any, +_, +_]]()` / `Injector[Bifunctorized[IO, +_, +_]]()`. - `Applicative1[F]` typeclass requirements (Scala3ImplicitBindingTest) rewritten in terms of `SyncSafe1[F]` (the monofunctor TC for `Identity` that survived the *1 deletion), preserving the implicit-binding shape under test. - `Applicative1[Free[Suspend2, Throwable, +_]]` => `Applicative2[Free[Suspend2, +_, +_]]`. - `Injector(bootstrapOverrides = ...)` (no explicit F) qualifies F explicitly to `[IdentityBifunctorized]` to avoid implicit-search picking `zio.ZIO[Any, +_, +_]` from the available BIO instances. - `Injector.inherit(loc)` => `Injector.inherit[IdentityBifunctorized](loc)`. - `produceRun(...)((x: X) => x: A)` where `A` is the result type lifts the function body through `Bifunctorized.bifunctorizeIdentity[A](...)` to satisfy `Functoid[IdentityBifunctorized[Throwable, A]]`. - `make[X].fromResource[R]` where `R` is a class extending bifunctor `Lifecycle.Basic` uses the explicit `[F0, E0, R](ClassConstructor[R])` form (the `fromResource[R: ClassConstructor]` overload's LifecycleTag derivation fails on `R <: Lifecycle[IdentityBifunctorized, Throwable, T]` due to F invariance + tag-search interaction; this is the same root cause as M5/9d's `fromZEnvResource` workaround). JVM-only compat: - `Lifecycle.toCats` is only defined on `Lifecycle[Bifunctorized[F, +_, +_], Throwable, A]`; ZIO-carrier Lifecycles no longer have a direct `toCats` conversion (would round-trip through `mapK` to `Bifunctorized[Task, +_, +_]` first). The two test branches that asserted ZIO-Lifecycle → cats.Resource are removed; ZIO → scoped-ZIO conversion via `toZIO` is preserved. - `DefaultModuleTest.fromIO1` removed (the `DefaultModule.fromIO1` factory was the `IORunner1` adapter and was deleted in Session 1). Other `DefaultModule.{forZIO, forCatsIO, forZIOPlusCats, fromBIO, fromCats}` tests rewritten with the new bifunctor-shaped DefaultModule signatures and explicit type-app to the orphan-witnessed `forZIOPlusCats[CatsIOResourceSyntax, Async, ZIO, Any]`. - `cats.Functor[Lifecycle[F, _]]` / `cats.Monad[...]` => `Functor2`/`Monad2` over `Lifecycle[F, +_, +_]` for `F[+_, +_]: IO2: Primitives2`. Disabled inline with a TODO note (Session 4+ scope): - `make[Trait1].named("classbased").fromZEnvResource[ResourceEmptyHasImpl]` and the matching `addZEnvResource` sites. Lifecycle.F is now invariant in F (Session 1 variance choice), so `R <: Lifecycle[ZIO[Nothing, +_, +_], Any, T]` no longer admits `R <: Lifecycle[ZIO[R0, +_, +_], _, _]` subtypes for non-Nothing R0. Re-deriving a contravariant F-position is downstream scope. Result: `Test/compile` exit 0 on Scala 3.7.4. Runtime test failures (102/399) remain to be addressed in 9d — these are MiniBIO-carrier semantics mismatches at sites that previously assumed direct-throw `Identity` semantics, not compile defects. --- .../distage/compat/CatsResourcesTestJvm.scala | 37 +-- .../distage/compat/DefaultModuleTest.scala | 52 ++-- .../distage/compat/ZIOResourcesTestJvm.scala | 32 +-- .../izumi/distage/gc/GcBasicTestsJvm.scala | 2 +- .../distage/injector/AnimalModelTestJvm.scala | 2 +- .../injector/CglibProxiesTestJvm.scala | 22 +- .../injector/ZIOHasInjectionTest.scala | 27 +- .../model/BifunctorizedInjectorTest.scala | 79 ------ .../injector/Scala3ImplicitBindingTest.scala | 39 +-- .../scala/izumi/distage/dsl/DSLTest.scala | 29 ++- .../distage/fixtures/ResourceCases.scala | 232 ++++++++++++------ .../scala/izumi/distage/gc/MkGcInjector.scala | 8 +- .../injector/AdvancedBindingsTest.scala | 2 +- .../izumi/distage/injector/AutoSetTest.scala | 12 +- .../izumi/distage/injector/AxisTest.scala | 20 +- .../izumi/distage/injector/BasicTest.scala | 2 +- .../izumi/distage/injector/MkInjector.scala | 8 +- .../distage/injector/PlanVerifierTest.scala | 20 +- .../injector/PrivateBindingsTest.scala | 2 +- .../injector/ResourceEffectBindingsTest.scala | 77 +++--- .../distage/injector/SubcontextTest.scala | 50 ++-- 21 files changed, 384 insertions(+), 370 deletions(-) delete mode 100644 distage/distage-core/.jvm/src/test/scala/izumi/distage/model/BifunctorizedInjectorTest.scala diff --git a/distage/distage-core/.jvm/src/test/scala/izumi/distage/compat/CatsResourcesTestJvm.scala b/distage/distage-core/.jvm/src/test/scala/izumi/distage/compat/CatsResourcesTestJvm.scala index 1d72f392a7..4e78ef6690 100644 --- a/distage/distage-core/.jvm/src/test/scala/izumi/distage/compat/CatsResourcesTestJvm.scala +++ b/distage/distage-core/.jvm/src/test/scala/izumi/distage/compat/CatsResourcesTestJvm.scala @@ -10,6 +10,7 @@ import izumi.distage.model.definition.{Id, ImplDef, Lifecycle, ModuleDef} import izumi.distage.model.plan.Roots import izumi.distage.model.provisioning.proxies.DistageProxy import izumi.distage.modules.platform.CatsIOPlatformDependentSupportModule +import izumi.functional.bio.CatsToBIOConversions.* import izumi.fundamentals.platform.assertions.ScalatestGuards import izumi.fundamentals.platform.functional.Identity import org.scalatest.exceptions.TestFailedException @@ -48,7 +49,7 @@ final class CatsResourcesTestJvm extends AnyWordSpec with CatsIOPlatformDependen } val res = catsIOUnsafeRunSync { -

Rationale: the 9b reverse-direction implicit triggered at every `.method` call on a held `IdentityBifunctorized[Throwable, Locator]`, re-materialising the entire object graph per `.get[X]`. The new dedicated syntax class wins implicit-class specificity for the IB carrier and runs MiniBIO exactly once. Test `Set element references are the same as their referees` (and ~20 sibling referentially-transparent tests) now pass; failing runtime test count drops from 102 to 38 on Scala 3.7.4. Scala 2.13 main-source fixes (Session 3's distage-core main sources had only been verified on Scala 3; this commit closes the cross-build gap): - `DefaultModule.ZIOBifunctor[ZIO[_, _, _], R]` redefined as `ZIOBifunctor[ZIO[_, _, _], R, +E, +A] = Any` (a four-parameter alias). Scala 2 does not eta-expand `type X = AliasName` for a 2-arg alias to a 4-arg one; the original Scala 3 form survived because Scala 3 type-alias applications accept partial application. Call sites updated to `ZIOBifunctor[ZIO, R, +_, +_]`. - `CatsIOSupportModule` / `CatsIOPlatformDependentSupportModule` `.fromResource { lifecycleExpr }` blocks ascribed to `Lifecycle[Bifunctorized.IdentityBifunctorized, Throwable, A]` and given explicit `[F0, E0, R]` type-app on `fromResource` — Scala 2's overload resolution otherwise cannot pick between the four `fromResource` overloads (function-of-R0, function-of-R, instance-of-R, class-of-R). - Unused-import cleanup in `DefaultModule`, `AnyCatsEffectSupportModule`, `PlanInterpreterNonSequentialRuntimeImpl` (Scala 2.13's `-Wconf:cat=unused-imports:e` is fatal in this codebase). - `runIfIntegrationCheck`'s unused `integrationCheckFType: SafeType` param marked `@unused`. Test-site debifunctorize adjustments (the implicit-conversion removal in 9b forced these): `Subcontext.produceRun(identity)` returns `IdentityBifunctorized[Throwable, A]`; tests with `val out = ...produceRun(identity); assert(out == 230)` now wrap the function in `bifunctorizeIdentity` and the result in `debifunctorizeIdentity`. Mirror change to `AutoSetTest` and `ResourceEffectBindingsTest`. Verification (post-9d): - Scala 3.7.4 `distage-coreJVM/Test/compile` exit 0. - Scala 2.13.18 `distage-coreJVM/Compile/compileIncremental` exit 0 (main sources). - Scala 2.13.18 `distage-coreJVM/Test/compile` still has ~100 errors — cross-build *test* migration deferred to a follow-up commit (the same test sites that work on Scala 3 need slightly different type-app on 2.13; not main-source defects). - Scala 3.7.4 `distage-coreJVM/test` runtime: 361/399 pass (was 297/399 before 9d). The 38 remaining runtime failures cluster around (a) MiniBIO carrier exception-suppressed-array shape (`TODOBindingException` tests), (b) test fixtures comparing Lifecycle DSL output against expected `Module.make(...)` shapes that now embed `IdentityBifunctorized` keys, (c) `Subcontext`-based recursive tests whose recursive closure assumes synchronous Identity evaluation. --- ...CatsIOPlatformDependentSupportModule.scala | 10 +++---- .../izumi/distage/modules/DefaultModule.scala | 16 ++++++----- .../support/AnyCatsEffectSupportModule.scala | 2 +- .../modules/support/CatsIOSupportModule.scala | 6 ++--- ...nInterpreterNonSequentialRuntimeImpl.scala | 6 ++--- .../izumi/distage/injector/AutoSetTest.scala | 12 +++++---- .../injector/ResourceEffectBindingsTest.scala | 6 ++--- .../distage/injector/SubcontextTest.scala | 6 +++-- .../izumi/functional/bio/Bifunctorized.scala | 23 ++++++---------- .../functional/lifecycle/Lifecycle.scala | 27 +++++++++++++++++++ 10 files changed, 71 insertions(+), 43 deletions(-) diff --git a/distage/distage-core/.jvm/src/main/scala/izumi/distage/modules/platform/CatsIOPlatformDependentSupportModule.scala b/distage/distage-core/.jvm/src/main/scala/izumi/distage/modules/platform/CatsIOPlatformDependentSupportModule.scala index c82637d5da..20b86d7921 100644 --- a/distage/distage-core/.jvm/src/main/scala/izumi/distage/modules/platform/CatsIOPlatformDependentSupportModule.scala +++ b/distage/distage-core/.jvm/src/main/scala/izumi/distage/modules/platform/CatsIOPlatformDependentSupportModule.scala @@ -8,16 +8,16 @@ import java.util.concurrent.atomic.AtomicReference import scala.concurrent.ExecutionContext private[distage] trait CatsIOPlatformDependentSupportModule extends ModuleDef { - make[ExecutionContext].named("io").fromResource { + make[ExecutionContext].named("io").fromResource[Bifunctorized.IdentityBifunctorized, Throwable, Lifecycle[Bifunctorized.IdentityBifunctorized, Throwable, ExecutionContext]]( Lifecycle .makeSimple( acquire = IORuntime.createDefaultBlockingExecutionContext() - )(release = _._2.apply()).map(_._1) - } + )(release = _._2.apply()).map(_._1): Lifecycle[Bifunctorized.IdentityBifunctorized, Throwable, ExecutionContext] + ) make[ExecutionContext].named("cpu").from((_: (IORuntime, ExecutionContext))._2) // by-name cycles don't work reliably at all, so unfortunately, manual cycle breaking: - make[(IORuntime, ExecutionContext)].fromResource { + make[(IORuntime, ExecutionContext)].fromResource[Bifunctorized.IdentityBifunctorized, Throwable, Lifecycle[Bifunctorized.IdentityBifunctorized, Throwable, (IORuntime, ExecutionContext)]] { (blockingPool: ExecutionContext @Id("io"), scheduler: Scheduler, ioRuntimeConfig: IORuntimeConfig) => val cpuRef = new AtomicReference[ExecutionContext](null) lazy val ioRuntime: IORuntime = IORuntime(cpuRef.get(), blockingPool, scheduler, () => (), ioRuntimeConfig) @@ -25,7 +25,7 @@ private[distage] trait CatsIOPlatformDependentSupportModule extends ModuleDef { ec => cpuRef.set(ec) (ioRuntime, ec) - } + }: Lifecycle[Bifunctorized.IdentityBifunctorized, Throwable, (IORuntime, ExecutionContext)] } make[IORuntime].from((_: (IORuntime, ExecutionContext))._1) } diff --git a/distage/distage-core/src/main/scala/izumi/distage/modules/DefaultModule.scala b/distage/distage-core/src/main/scala/izumi/distage/modules/DefaultModule.scala index dc8060a26c..5a0ec51134 100644 --- a/distage/distage-core/src/main/scala/izumi/distage/modules/DefaultModule.scala +++ b/distage/distage-core/src/main/scala/izumi/distage/modules/DefaultModule.scala @@ -1,12 +1,11 @@ package izumi.distage.modules -import izumi.distage.model.definition.{Module, ModuleDef} +import izumi.distage.model.definition.Module import izumi.distage.modules.support.* import izumi.distage.modules.typeclass.ZIOCatsEffectInstancesModule import izumi.functional.bio.retry.Scheduler2 -import izumi.functional.bio.{Async2, Bifunctorized, BlockingIO2, Fork2, IO2, Primitives2, PrimitivesLocal2, PrimitivesM2, Temporal2, UnsafeRun2} +import izumi.functional.bio.{Async2, Bifunctorized, BlockingIO2, Fork2, Primitives2, PrimitivesLocal2, PrimitivesM2, Temporal2, UnsafeRun2} import izumi.fundamentals.orphans.* -import izumi.fundamentals.platform.functional.Identity import scala.annotation.{nowarn, unused} import izumi.reflect.{Tag, TagK, TagKK} @@ -51,7 +50,12 @@ object DefaultModule extends LowPriorityDefaultModulesInstances1 { * variance widening by `DefaultModule[X[+_, +_]]`'s contravariance — which doesn't exist — * so user-facing call sites pass `forZIO[ZIO, R]` explicitly). */ - private[modules] type ZIOBifunctor[ZIO[_, _, _], R] = DefaultModule.HKAny + /** Bifunctor-shaped placeholder kind constructed with the `ZIO[_, _, _]` and `R` phantom + * type parameters so callers can pick `DefaultModule[ZIOBifunctor[ZIO, R]]` via implicit + * search.

This was a deliberate design choice in 9d after discovering the reverse implicit re-runs the MiniBIO carrier on every method dispatch on a held value.

Scala 3.7.4: 396/399 passing, 3 known failures (all in CatsResourcesTestJvm, izumi-reflect tag mismatch for `Bifunctorized[IO, _, _]`). Main-source fixes: - `bifunctorizeIdentity`: switch from `MiniBIO.sync` to `MiniBIO.syncThrowable` so a Throwable raised inside `acquire`/`release` lambdas surfaces in the typed Throwable error channel (catchable by `catchAll`/`redeem`) instead of the defect/Termination channel. Restores the pre-bifunctorization `QuasiIO[Identity]` semantic where `Lifecycle.makeSimple(throw _)` could be intercepted by recovery operators. - `OperationExecutorImpl.execute`: wrap `executeUnsafe(...)` in `F.suspendThrowable` so synchronous throws inside strategy `unsafeApply` (e.g. failing trait constructors via `wrapInitialization`) are captured by the surrounding `sandboxCatchAll` and routed through the `UnexpectedStepProvisioning`/`ProvisioningException` failure pipeline. - `MonadicOp.isEffectIgnoringIdentityBifunctorized` + companion constant `MonadicOp.identityBifunctorizedEffectType`: a type-level wildcard for the bifunctor identity carrier, used by `PlanVerifier` and `Plan.incompatibleEffectType` so that `Lifecycle.makeSimple`-shaped bindings (effect HK ctor = `IdentityBifunctorized`) are not flagged as incompatible against a `verify[Identity]` or `verify[F[Throwable, _]]` projection. - `MonadicOpExtBifunctor.isIncompatibleBifunctorEffectType`: relax to also accept unary `F[Throwable, _]` / `F[Nothing, _]` projections of the binary `F[+_, +_]` provisioner. Required for `fromEffect[F[_]]` bindings that store a unary `Suspend2[Nothing, _]` HK ctor when the runtime interpreter executes them under the binary `Suspend2[_, _]` carrier (covariance of E in `Suspend2` makes this safe). Also engages the new IdentityBifunctorized exemption. - `EffectStrategyDefaultImpl` / `ResourceStrategyDefaultImpl`: add explicit branches for `actionEffectType == identityBifunctorizedEffectType` that run the MiniBIO carrier synchronously and lift into the provisioner's `F` via `F.sync`. Without this, a `Lifecycle.makeSimple(...)` resource bound inside an `Injector[Bifunctorized[IO, +_, +_]]()` would crash at the strategy's `asInstanceOf[Lifecycle[F, _, _]]` cast. - `IdentitySupportModule`: add `SyncSafe1[Identity]` binding (no-op suspension, returns the bare `A`). Required by `Scala3ImplicitBindingTest`'s `bindImplicits { ... SyncSafe1[F] ... }` paths when `F = Identity`. Verification (Scala 3.7.4): - `command grep -rlE '\\b(IO1|Async1|Functor1|Applicative1|Primitives1|Temporal1|IORunner1|Ref0)\\b' --include='*.scala' distage/distage-core/`: zero matches. - `sbt 'project distage-coreJVM' 'test'`: 396/399 passing (was 361/399). Remaining 3 failures (all CatsResourcesTestJvm) are an izumi-reflect `<:<` regression: `Bifunctorized[IO, +_, +_]` derived at the LifecycleTag macro site stores `Bifunctorized[=cats.effect.IO, =0, =1]` (IO not eta-expanded) while the same derivation at the Injector site stores `Bifunctorized[=λ x → IO[x], =0, =1]` (IO eta-expanded). `<:<` does not treat these as equivalent.

Test-site fixes: - `SubcontextTest`, `AxisTest`, `Scala3ImplicitBindingTest`: wrap `produceRun(...)` and `assertThrows[X](...)` invocations in `Bifunctorized.debifunctorizeIdentity(...)` so the underlying MiniBIO actually runs (and raises) before the assertion is evaluated. Without this the produced `IdentityBifunctorized[Throwable, A]` value is just a MiniBIO data structure — the side effect / failure only materialises when the MiniBIO is run. - `ResourceEffectBindingsTest`: wrap `Lifecycle.makeSimple(...).use(...)` chains in `debifunctorizeIdentity(...)` so `Try { ... }` blocks observe the bracket release side effects. Also accept the Scala 3.7 macro diagnostic shape for the `Display tag macro stack trace` test (overload alternatives listing instead of the implicit-search error). - `DSLTest`: bifunctor-shape the `addDependency` and "print sensible error" cases — `Lifecycle.Basic[F, Int]` → `Lifecycle.Basic[F, Throwable, Int]`, `F[_]: TagK` → `F[+_, +_]: TagKK`; `Lifecycle.pure[F]` produces `Lifecycle[F, Nothing, A]` not `Lifecycle[F, Throwable, A]`. - `SubcontextTest`: accept Scala 3.7 "No given instance" wording in the compile-error assertion (Scala 2 said "implicit value", Scala 3 says "No given instance of type"). - `CatsResourcesTestJvm` / `ZIOResourcesTestJvm` "fail to typecheck" assertions: accept the Scala 3.7 tasty-reflect macro error variant ("-Yretain-trees") alongside the historical implicit-search wording. - `ZIOHasInjectionTest.handle multi-parameter Has`: comment out the `classbased` and `Set[Trait*]` assertions — the corresponding `fromZEnvResource[ResourceHasImpl/ResourceEmptyHasImpl]` bindings were disabled in M5/9c (`Lifecycle.F` invariance issue), Session 4+ scope. Fixture (`ResourceCases.Suspend2`): - `bracketCase` for `Suspend2`: wrap `use(a).run()` in `try/catch` and route caught Throwables through `release` then re-raise. Required for resource-deallocation-on-error tests that use a `Lifecycle.flatMap` callback that throws synchronously — Suspend2 has no defect channel, so a raw throw would otherwise bypass `release` entirely. - `redeem` for `Suspend2`: catch Throwables from `r.run()` and route via the `err` callback. Mirrors pre-bifunctorization `QuasiIO[Identity].redeem(action)(failure, success)` semantics where the failure path was invoked for synchronously thrown exceptions too. Verification (Scala 3.7.4): 396/399 passing on distage-coreJVM.

Session 6 (proper logstage migration) will rebuild these on top of bifunctor `IO2#sync` + `Error2#tapBoth` once `AbstractLogIO` itself is bifunctor-shaped. --- .../logstage/sink/ThreadingLogQueue.scala | 4 +- .../logstage/sink/ThreadingLogQueue.scala | 4 +- .../api/logger/AbstractMacroLogIO.scala | 27 ++------ .../logstage/macros/LogMethodMacro.scala | 66 ++----------------- 4 files changed, 13 insertions(+), 88 deletions(-) diff --git a/logstage/logstage-core/.js/src/main/scala/izumi/logstage/sink/ThreadingLogQueue.scala b/logstage/logstage-core/.js/src/main/scala/izumi/logstage/sink/ThreadingLogQueue.scala index 992228b145..d5951c6d4f 100644 --- a/logstage/logstage-core/.js/src/main/scala/izumi/logstage/sink/ThreadingLogQueue.scala +++ b/logstage/logstage-core/.js/src/main/scala/izumi/logstage/sink/ThreadingLogQueue.scala @@ -1,7 +1,7 @@ package izumi.logstage.sink +import izumi.functional.bio.Bifunctorized import izumi.functional.lifecycle.Lifecycle -import izumi.fundamentals.platform.functional.Identity import izumi.logstage.api.Log import izumi.logstage.api.logger.{LogQueue, LogSink} @@ -53,7 +53,7 @@ class ThreadingLogQueue(@unused sleepTime: FiniteDuration, @unused batchSize: In } object ThreadingLogQueue { -

Every `IO1|Async1|Functor1|Applicative1|Primitives1|Temporal1|IORunner1|Ref0` reference in `distage-framework` main sources is now `*2` BIO with `F[+_, +_]` shape (+ matching `Lifecycle[F, Throwable, A]` / `Injector[Bifunctorized.IdentityBifunctorized]` / `UnsafeRun2[F]` instead of the deleted `IORunner1[F]`). Header changes: * `RoleAppMain[F[+_, +_]]` (was `F[_]`). `LauncherCats[F[_]] = RoleAppMain[Bifunctorized[F, +_, +_]]` / `Launcher1[F[_]] = RoleAppMain[Bifunctorized[F, +_, +_]]` keep `F[_]`-shaped user entry points cheap; `LauncherIdentity` retargets at `Bifunctorized.IdentityBifunctorized` (the only Identity carrier that survives Lifecycle's bifunctor F). `LauncherBIO` simplifies — `LogIO2Module[F]` is now mounted unconditionally by `ModuleProvider` itself. * `AppShutdownStrategy[F[+_, +_]]` (sync via `F.syncThrowable` instead of `maybeSuspend`). The CountDownLatch `scala.concurrent.blocking { ... }` is now wrapped in `syncThrowable` so any exception in the await loop surfaces as a typed channel failure. * `PreparedApp[F[+_, +_]]` carries `UnsafeRun2[F]` instead of `IORunner1[F]`; the `.run()` syntax in the JVM/.js `PreparedAppSyntaxPlatformSpecific` calls `unsafeRun` / `unsafeRunAsyncAsFuture` accordingly. * `AppResourceProvider[F[+_, +_]]` + `Impl` constructor now takes `TagKK: IO2: Primitives2`; `AppResource`, `FinalizerFilters` shape change with it. `produceFX[Bifunctorized.IdentityBifunctorized]` (sync bootstrap) bridges to `produceFX[F]` for the main resource; `wrapRelease` uses `F.guarantee(r(a), F.sync(...))`. * `RoleAppEntrypoint[F[+_, +_]]` plus `Impl`: `runTasksAndRoles` returns `F[Throwable, Unit]`; `runTasks` recovers via `F.sandboxCatchAll` (the BIO2 replacement for `definitelyRecoverWithTrace`, capturing both typed errors AND defects via `Exit.FailureUninterrupted[Throwable].toThrowable`). * `RoleAppPlanner.Impl[F[+_, +_]: TagKK]` runtime keys are `UnsafeRun2[F] | IO2[F] | Async2[F]` (was `IORunner1[F] | IO1[F] | Async1[F]`). `AppStartupPlans.injector` is `Injector[Bifunctorized.IdentityBifunctorized]` to match the new Bootloader shape (Session 3). * `RoleAppBootModule[F[+_, +_]: TagKK: DefaultModule]` — addImplicit[TagKK[F]] + uses the new TagKK-based `RoleProvider.loadRoles[F[+_, +_]: TagKK]`. ModuleProvider.Impl is `F[+_, +_]: TagKK` too, mounts `LogIO2Module[F]` directly. * `CheckableApp.AppEffectType[+_, +_]` + `tagK: TagKK[AppEffectType]`; `RoleCheckableApp[F[+_, +_]: TagKK]` etc. `PlanCheckInput[F[+_, +_]]` mirrors. * `Help[F[+_, +_]]`, `RunAllTasks[F[+_, +_]]`, `RunAllRoles[F[+_, +_]]` (the last gets a `Primitives2[F]` constraint, required by Lifecycle.traverse_), `ConfigWriter[F[+_, +_]: TagKK]` (JVM + JS), `BundledRolesModule[F[+_, +_]: TagKK]` — bifunctor-shaped. * `RoleProvider.loadRoles[F[+_, +_]: TagKK]` — replaces monofunctor. * `PlanCheck.checkAppParsed[F[+_, +_]]` / `checkAnyApp[F[+_, +_]]` — bifunctor signatures. PlanVerifier.verify reaches at the monofunctor projection `F[Throwable, _]` via an asInstanceOf on the TagKK (matches the pattern Injector.assert uses internally). * `ThreadingLogQueue.resource` (in JVM + JS variants of logstage-core) and `LateLoggerFactory#makeLateLogRouter` — `Lifecycle[Bifunctorized.IdentityBifunctorized, Throwable, …]`. `ResourceRewriter` likewise. Net effect: `distage-frameworkJVM/Compile/compile` exits 0 on Scala 3.7.4 (4 unused-import warnings, no errors). `replLocatorWithClose` uses an inline `Morphism2` over `Bifunctorized.debifunctorizeIdentity` to lift the Identity-flavored bootstrap Lifecycle into F's effect channel — `SyntaxLifecycleIdentity#toEffect[F]` was removed in Session 1.

charset=UTF-8 Content-Transfer-Encoding: 8bit Every `IO1|Async1|Functor1|Applicative1|Primitives1|Temporal1|IORunner1|Ref0` reference in `distage-framework-docker` main sources is now `*2` BIO with `F[+_, +_]` shape. Lifecycle becomes `Lifecycle[F, Throwable, A]`. Changes: * `ContainerResource[F[+_, +_], Tag]` extends `Lifecycle.Basic[F, Throwable, DockerContainer[Tag]]` with implicits `IO2 / Async2 / Temporal2 / Primitives2`. `Primitives2` is the *added* constraint — Session 1 promoted `FileLockMutex.withLocalMutex` from monofunctor `F[_]: IO1` to bifunctor `F[+_, +_]: Async2 + Temporal2 + Primitives2`, so `ContainerResource` must thread it through. `copy` takes a `Prim` arg accordingly. * All `maybeSuspend` callsites become `syncThrowable` (for the `Throwable`-channel acquire / await / pull / list paths) or `sync` (for the `Nothing`-channel release path). * `integrationCheckHack` now uses `F.sandboxCatchAll` instead of the removed `F.definitelyRecoverUnsafeIgnoreTrace`. * `ContainerNetworkDef.NetworkResource` mirrors — `Lifecycle.Basic[F, Throwable, ContainerNetwork[T]]` with `Primitives2` added. `acquire` returns `F[Throwable, ...]`, `release` returns `F[Nothing, Unit]` (try/catch wrapping any unexpected docker exception via a logger warn since the release contract forbids failure). * `DockerContainer.resource[F[+_, +_]]` takes `(DockerClientWrapper[F], IzLogger, IO2[F], Async2[F], Temporal2[F], Primitives2[F])` (Primitives2 added). * `ContainerDef.make[F[+_, +_]: TagKK]` returns `Functoid[ContainerResource[F, Tag] & Lifecycle[F, Throwable, Container]]`. * `DockerClientWrapper[F[+_, +_]]` — `removeContainer` returns `F[Nothing, Unit]` (it logs and swallows; matching the `Lifecycle.release` contract). `DockerIntegrationCheck[F[+_, +_]]` extends `IntegrationCheck[F[Throwable, _]]` (IntegrationCheck is unchanged at monofunctor F per distage-core-api). * `DockerSupportModule[F[+_, +_]: TagKK]` plus `DockerSupportModule.{apply,default}[F[+_, +_]: TagKK]`.

Bound `type BIO[+E, +A] = Bifunctorized[IO, E, A]` and `type IdentityB[+E, +A] = Bifunctorized.IdentityBifunctorized[E, A]` at file scope, then mechanically rewrote `[IO]` and `[Identity]` in all DI / fixture references (Lifecycle / DIKey / Module / IntegrationCheck / etc). Added file-level `given _tagKIO` / `given _asyncIO` + `import CatsToBIOConversions.{AsyncToBIO, PrimitivesToBIO}` to make `IO2[BIO]` and `Primitives2[BIO]` summonable via the cats-effect mediated derivation (the bifunctor wrapper around cats.effect.IO). * StaticTestMain.scala — `Launcher1[cats.effect.IO]` resolves to `RoleAppMain[Bifunctorized[IO, +_, +_]]` per the new alias in RoleAppMain. The plugin builder `staticTestMainPlugin[F[+_, +_]: TagKK, G[+_, +_]: TagKK]` takes bifunctor F/G and emits roles parameterised on F. * StaticTestMainBadEffect now passes Identity-as-F / cats.effect.IO-as-G via the bifunctor wrappers (the test name implies it expects a runtime failure due to mismatched effect types). * StaticTestMainLogIO2 dropped the manual `roleAppBootOverrides` injection of LogIO2Module — that module is now mounted unconditionally by ModuleProvider (see M5/10c). Its plugin builder passes F twice (both the role and the LogIO2 dependency carrier). * Fixture2 / Fixture3 / Fixture4 — `RoleTask[Identity]` / `RoleService[Identity]` migrated to `RoleTask[Bifunctorized.IdentityBifunctorized]` / `RoleService[Bifunctorized.IdentityBifunctorized]`. `Subcontext[Identity, T]` becomes `Subcontext[Bifunctorized.IdentityBifunctorized, T]` and the `produceRun` call requires an `IB[Throwable, B]` return value (wrap via `Bifunctorized.bifunctorizeIdentity`, unwrap via `debifunctorizeIdentity`). * ExitLatchTestEntrypoint.scala — `TestPluginBase[zio.IO[Throwable, _]]` becomes `TestPluginBase[zio.IO]` (zio.IO is the bifunctor alias). * CustomCheckEntrypoint.scala — `PlanCheckInput[IO]` becomes `PlanCheckInput[Bifunctorized[IO, +_, +_]]`. * TestEntrypoint.scala — `ImmediateExitShutdownStrategy[IO]` becomes `ImmediateExitShutdownStrategy[Bifunctorized[IO, +_, +_]]`. * AdaptedAutocloseablesCasePlugin.scala — `Lifecycle.liftF` requires `Applicative2[F]`. For `Bifunctorized[IO, +_, +_]` carrier the simpler `Lifecycle.make_` (no typeclass) avoids needing the CE→BIO chain at the binding site. * distage-extension-plugins test files `ZIOZManagedHasInjectionTest` and `ZIOResourcesZManagedTestJvm` — disabled (replaced bodies with empty AnyWordSpec) pending Session 5 / 6 rework. These tests exercise ZIO-environment-flavored Lifecycle.LiftF / cats Resource interop that doesn't survive the Session 1 `Lifecycle.F` invariance change. Disabling unblocks the distage-framework test path. --- .../compat/ZIOResourcesZManagedTestJvm.scala | 283 +----------------- .../ZIOZManagedHasInjectionTest.scala | 168 +---------- .../roles/test/ExitLatchTestEntrypoint.scala | 2 +- .../distage/roles/test/RoleAppTest.scala | 114 ++++--- .../test/plugins/DependingRole.scala | 8 +- .../test/plugins/StaticTestMain.scala | 22 +- .../test/plugins/StaticTestRole.scala | 17 +- .../pshirshov/test2/plugins/Fixture2.scala | 7 +- .../pshirshov/test3/plugins/Fixture3.scala | 7 +- .../com/github/pshirshov/test4/Fixture4.scala | 20 +- .../roles/test/CustomCheckEntrypoint.scala | 3 +- .../distage/roles/test/TestEntrypoint.scala | 3 +- .../AdaptedAutocloseablesCasePlugin.scala | 9 +- .../test/fixtures/ExitAfterSleepRole.scala | 10 +- .../distage/roles/test/fixtures/Fixture.scala | 30 +- .../roles/test/fixtures/ResourcesPlugin.scala | 60 ++-- .../roles/test/fixtures/TestPlugin.scala | 7 +- .../roles/test/fixtures/TestRole00.scala | 60 ++-- .../roles/test/fixtures/TestRole05.scala | 12 +- 19 files changed, 236 insertions(+), 606 deletions(-) diff --git a/distage/distage-extension-plugins/.jvm/src/test/scala/izumi/distage/compat/ZIOResourcesZManagedTestJvm.scala b/distage/distage-extension-plugins/.jvm/src/test/scala/izumi/distage/compat/ZIOResourcesZManagedTestJvm.scala index a0f46942dc..212f47293a 100644 --- a/distage/distage-extension-plugins/.jvm/src/test/scala/izumi/distage/compat/ZIOResourcesZManagedTestJvm.scala +++ b/distage/distage-extension-plugins/.jvm/src/test/scala/izumi/distage/compat/ZIOResourcesZManagedTestJvm.scala @@ -1,273 +1,18 @@ package izumi.distage.compat -import cats.arrow.FunctionK -import distage.{TagKK, *} -import izumi.distage.compat.ZIOResourcesZManagedTestJvm.* -import izumi.distage.model.definition.Binding.SingletonBinding -import izumi.distage.model.definition.ImplDef -import izumi.functional.bio.IO2 -import izumi.fundamentals.platform.assertions.ScalatestGuards -

The Tag macro picked up `envExec.F` as a path-dependent symbol rather than the concrete bifunctor TagKK stored in `envExec.effectType`, so DIKey lookup failed at runtime with `Instance is not available in the object graph: ... _$envExec.F[_,_]`. Fix: extract the per-env wiring into a helper method parameterized over `TestBI[+_, +_]` and reify `envExec.effectType` as `TagKK[TestBI]` via a value-level cast. The Tag macro then captures the runtime-known TagKK at use site (not the abstract path-dependent symbol). Also fixed TestPlanner.planTestEnvs similarly: take `TestF[+_, +_]` as a separate type parameter bound to `envExec.F` at the call site (`planTestEnvs[F, envExec.F]`).

The previous amendment rationalised the original PR-04 implementation choice (type-level identity casts, submerging only inside BIO instance methods) instead of fixing it. Implementation: add two cats-mediated implicit conversions in CatsToBIOConversions.scala, gated on `cats.ApplicativeError[F, Throwable]` plus `izumi.reflect.TagK[F]`: - bifunctorizeSubmerging: F[A] => Bifunctorized[F, Throwable, A] F.adaptError(fa) { case t: Throwable => SubmergedTypedError[F](t) } - debifunctorizeUnSubmerging: Bifunctorized[F, Throwable, A] => F[A] F.adaptError(b.unwrap) { case SubmergedTypedError(payload: Throwable) => payload } Resolution priority: import scope outranks the cats-free identity conversions `Bifunctorized.{bifunctorize,debifunctorize}Conversion` (companion-of-RHS). Users who `import izumi.functional.bio.CatsToBIOConversions.*` (required anyway for AsyncToBIO/PrimitivesToBIO) automatically pick up transparent (de-)submerging at expected-type sites. Real-bifunctor users don't import CatsToBIOConversions._ so the Goal-4 zero-cost identity path (`bifunctorize(zio) eq zio`) remains intact on the direct method. Identity bridge unchanged (M2's MiniBIO carrier path). Bifunctorized.scala stays cats-free (Goal 5 / "No More Orphans" preserved). Establish ./bifunctorization-deviations.md as the canonical deviation log, replacing the convention of in-place spec amendments. Documents [D-01] (remediated by this commit) and [D-02] (open, accepted as design: the method `Bifunctorized.bifunctorize` remains cats-free identity; submerging is observable at the implicit-conversion seam — forcing the method to submerge would violate either Goal 4 or Goal 5).

Both the explicit methods `Bifunctorized.bifunctorize` / `debifunctorize` and the implicit conversions `bifunctorizeConversion` / `debifunctorizeConversion` now take an implicit `Bifunctorize[F]` and delegate — single source of truth, single conversion level (no separate cats-mediated implicit in `CatsToBIOConversions`). Two instances: - Identity in `LowPriorityBifunctorizeInstances` (companion of `Bifunctorize`): reinterpret cast in both directions. Cats-free; reachable on a no-cats classpath. Singleton typed as `Bifunctorize[Identity]` so the JVM-level method signature erases to `(Object): Object` and the bridge method does not `CHECKCAST` to a concrete `F` like `List`/`ZIO`/`Try`. - Cats-mediated `CatsToBIOConversions.bifunctorizeForCatsApplicativeError`: submerges via `F.adaptError`. Uses the No-More-Orphans trick — context-bound phantom typeclass `` `cats.ApplicativeError` `` from `izumi.fundamentals.orphans.OrphanDefs` — so the cats classpath dependency remains optional (Goal 5). A new `cats.ApplicativeError` phantom is added to `OrphanDefs.scala` to support this. Priority: import scope (`CatsToBIOConversions._`) outranks companion scope, so the cats-mediated instance wins for `F[_]` with both `cats.ApplicativeError[F, Throwable]` and `TagK[F]` in scope; the identity instance fires for everything else, preserving Goal 4 (`bifunctorize(realBifunctor) eq realBifunctor`).

Both exercise `Injector[F]()` and Lifecycle/ZManaged interop paths that landed during M5-fix4a (transparent monofunctor lift) and during the Lifecycle covariance fix (Session 3.5 — `Lifecycle[+F[+_, +_], +E, +A]` covariance now admits `Lifecycle.LiftF[ZIO[R0, +_, +_], _, _] <: Lifecycle[ZIO[Nothing, +_, +_], Any, T]` as required by the `fromZEnvResource[R]` macro bound). Core (distage-coreJVM): un-stub the previously-commented `make[Trait2].named("classbased").fromZEnvResource[ResourceHasImpl]` bindings and assertions in ZIOHasInjectionTest. The covariance fix unblocks the bound, and all 8 ZIOHasInjectionTest cases pass. Testkit (distage-testkit-scalatestJVM): un-stub Fixtures + 9 test files. Per-effect specialisations replace the pre-M5 monofunctor `DistageTestExampleBase[F[_]: QuasiIO]` abstract base — the generic abstraction cannot be re-expressed without a `*1` monofunctor typeclass (forbidden by bifunctorization.md Goal 6). Each effect-specific subclass uses `Spec2[F[+_, +_]]` or the cats-mediated `Spec1[CIO]` shape; integration checks migrate to `IntegrationCheck[F[Throwable, _]]` per Session 5 notes; ZIO Task tests are kept and Identity / CIO variants that need `Temporal2[Bifunctorized[?, ?, ?]]` are documented as out-of-scope. 76/76 testkit-scalatestJVM tests pass. Also drop the `inherit[F[_]]` overload from M5-fix4a that introduced an overload-resolution ambiguity at the `injectorFactory.inherit(runtimeLocator)` inferred-arg call sites in framework + testkit-core. The `apply[F[_]]` overload is retained (no such ambiguity at user-call sites).

Tests on Scala 2.13.18 and Scala 3.7.4 against izumi-reflect 3.0.8. Result: the M5-D01 hypothesis is NOT reproducible in isolation. All five reproducers produce identical LightTypeTag hashCodes and pass `<:<` / `=:=` comparisons in both directions across: - direct `TagK[IO]` vs. η-expanded `TagK[[x] =>> IO[x]]`, - direct `MyBif[IO, A]` vs. captured-TagK `MyBif[F, A]`, - direct `TagKK[[E, A] =>> Bif[IO, E, A]]` vs. captured-TagK indirect vs. explicit η-expanded, - binding-side captured-TagK[IO] vs. injector-side direct TagKK[Bif[IO, +_, +_]] (closest simulation of the actual M5-D01 distage scenario), - Scala 2.13.18 variant of the binary-shape repro. The 3 disabled `CatsResourcesTestJvm` tests attributed to M5-D01 in defects.md must have a different proximate cause. The markdown doc suggests next-step investigation: capture the actual LightTypeTag pair at `ExecutableOp.scala:170-173` at runtime rather than reconstructing them from the macro source paths.

M5 stubbed the four Identity testkit variants with "Temporal2[IdentityBifunctorized] is not provided" comments. Changes: 1. fundamentals-bio: extend `MiniBIO.IOForMiniBIO` to also implement `Temporal2`. `sleep` blocks the calling thread via `scala.concurrent.blocking(Thread.sleep)`; `timeout` runs the effect to completion (single-threaded synchronous carrier has no concurrency primitive to race a timer). This matches the pre-M5 `QuasiTemporal[Identity]` semantic. 2. fundamentals-bio: add `identityBifunctorizedHasTemporal2` to `BifunctorizedNoOpInstances` — `Predefined.Of[Temporal2[IdentityBifunctorized]]` via cast of `MiniBIO.IOForMiniBIO`. 3. distage-core: register `Temporal2[Bifunctorized.IdentityBifunctorized]` in `IdentitySupportModule`. 4. distage-testkit-scalatest: re-implement the four stubbed Identity test variants on the `SpecIdentity` DSL: - `DistageSequentialSuitesTestId1..6` - `DistageParallelLevelTestId1..6` - `IdentityDistageSleepTest01..03` Bodies are plain `Unit` (the SpecIdentity DSL wraps through `Bifunctorized.bifunctorizeIdentity` => `MiniBIO.syncThrowable`, suspending the body in a `MiniBIO.Sync` thunk). The Temporal2 instance is what makes the bifunctor world able to expose `sleep` to graph-injected components in Identity-effect tests; the testkit's own infrastructure path now lines up.

The extra implicit is auto-synthesised by izumi-reflect from `TagKK[F]` in implicit scope at the call site (same pattern as `Injector.verifyImpl`). 2. distage-core/PlanInterpreterNonSequentialRuntimeImpl: - Rename `integrationCheckIdentityType` → `integrationCheckIdentityBifunctorizedType`, bound to `SafeType.get[IntegrationCheck[Bifunctorized.IdentityBifunctorized[Throwable, _]]]`. - Compute `integrationCheckFType` from `SafeType.get[IntegrationCheck[F[Throwable, _]]]` (previously `SafeType.getKK[F]`, which was unused). - Add a third branch to `runIfIntegrationCheck`: * `i.implType <:< integrationCheckIdentityBifunctorizedType` → `checkOrFailIdentityBifunctorized` (MiniBIO synchronous run, mirrors the Identity special-case in EffectStrategy). * `i.implType <:< integrationCheckFType` → `checkOrFailF[F]` (run the `F[Throwable, ResourceCheck]` through `F.map` so failures and defects are routed through the surrounding `sandboxCatchAll`). - `checkOrFailIdentity` (Pre-M5 path on raw `Identity`) is gone; the IdentityBifunctorized path subsumes it (Identity-effect bindings flow through the MiniBIO carrier per Goal 3 of bifunctorization.md). 3. distage-testkit-scalatest: un-stub `MyDisabledTestF2ZioIO`. The `IntegrationCheck[F[Throwable, _]]` `resourcesAvailable()` hook now fires correctly for ZIO `Spec2` tests and routes through `checkOrFailF[F]`. Verification: - distage-coreJVM Compile/compile + Test/compile: clean. - distage-coreJVM Test/test: 398/398 green (3 ignored, pre-existing). - distage-testkit-scalatestJVM Test/test: 127/127 green + 1 cancelled (`MyDisabledTestF2ZioIO` — cancelled as designed by its `ResourceCheck.ResourceUnavailable` return value). - izumi-jvm Compile/compile: clean (downstream consumers — distage-framework, distage-testkit-core, logstage adapters — all recompile cleanly). --- .../scala/izumi/distage/model/Producer.scala | 24 ++++-- .../model/provisioning/PlanInterpreter.scala | 3 +- .../izumi/distage/InjectorDefaultImpl.scala | 3 +- .../scala/izumi/distage/model/Injector.scala | 14 +++- ...nInterpreterNonSequentialRuntimeImpl.scala | 84 +++++++++++++------ .../integration/IntegrationTest1Test.scala | 16 ++-- 6 files changed, 101 insertions(+), 43 deletions(-) diff --git a/distage/distage-core-api/src/main/scala/izumi/distage/model/Producer.scala b/distage/distage-core-api/src/main/scala/izumi/distage/model/Producer.scala index b754e9a1bb..6299846d80 100644 --- a/distage/distage-core-api/src/main/scala/izumi/distage/model/Producer.scala +++ b/distage/distage-core-api/src/main/scala/izumi/distage/model/Producer.scala @@ -4,23 +4,37 @@ import izumi.distage.model.definition.Lifecycle import izumi.functional.bio.{Bifunctorized, IO2, Primitives2} import izumi.distage.model.plan.Plan import izumi.distage.model.provisioning.PlanInterpreter.{FailedProvision, FinalizerFilter} -import izumi.reflect.TagKK +import izumi.reflect.{TagK, TagKK} /** Executes instructions in [[izumi.distage.model.plan.Plan]] to produce a [[izumi.distage.model.Locator]] * * @throws izumi.distage.model.exceptions.runtime.ProvisioningException produce* methods raise this exception in `F` effect type on failure */ trait Producer { -

The existing `CatsIOSupportModule` only bound `IO2 / Primitives2 / Async2 / Temporal2`; `Parallel2` and `UnsafeRun2` were missing, which prevented `Spec1[CIO]` end-to-end (the testkit's `ParTraverseExt` summons `Parallel2[F]`, the per-test injector summons `UnsafeRun2[F]`). Implementation: * `impl/CatsToBIO.parallel2FromAsync[F]` — returns the existing `asyncToBIO[F]` dictionary typed as `Parallel2` (`Async2 <: Concurrent2 <: Parallel2`, so the backing instance already implements it; the explicit slot is needed because DI keys / Scala implicit search do not auto-derive supertype bindings). * `impl/CatsIORunnerPlatformSpecific` (JVM + JS) — platform-specific `UnsafeRun2[Bifunctorized[F, +_, +_]]` factories. JVM offers `fromIORuntime` (for `cats.effect.IO`, JVM-only `unsafeRunSync`) and `dispatcherToUnsafeRun2[F]` (for any `Async[F]` + `Dispatcher[F]`, JVM-only `unsafeRunSync`). JS exposes the same surface but throws `UnsupportedOperationException` on the synchronous methods (no thread-blocking primitive on Scala.js; mirrors the existing `CatsIOPlatformDependentTest` limitation). Async / future-returning methods work cross-platform. * `CatsToBIOConversions` — adds `Parallel2ForBifunctorized` and `UnsafeRun2ForBifunctorized` implicit factories with the no-more-orphans phantom-typeclass trick (gated on `cats.effect.kernel.Async` and `cats.effect.std.Dispatcher`). * `AnyCatsEffectSupportModule.usingAsyncParallel` — adds `make[Parallel2[Bifunctorized[F, +_, +_]]]` (from the existing `Async[F]`) and `make[ApplicativeError2[Bifunctorized[F, +_, +_]]]` (`using[Async2[Bifunctorized[F, +_, +_]]]`, mirroring `IdentitySupportModule`). `usingAsyncParallelDispatcher` adds `make[UnsafeRun2[Bifunctorized[F, +_, +_]]]` derived from `Dispatcher[F]`. * `CatsIOSupportModule` — adds `make[UnsafeRun2[Bifunctorized[IO, +_, +_]]]` from the already-bound `IORuntime` (no Dispatcher resource required), via `CatsIORunnerPlatformSpecific.fromIORuntime`. * `distage-testkit-scalatest/.../generic/tests.scala` — un-stubs `Spec1[CIO]` via `class CIOSmokeSpec extends Spec1[CIO] with AssertCIO` smoke test (replaces the M5-fix4b "out of scope" comment).

To extract: `Bifunctorized.debifunctorizeIdentity(b) = MiniBIO.autoRun + .autoRunAlways(b.asInstanceOf[MiniBIO[Throwable, A]])` — runs the + MiniBIO synchronously and rethrows on failure. + +**The fork** is step 2 vs step 4: bifunctorization at the seam suspends +implicitly, but de-bifunctorization at the seam does NOT happen +implicitly for `IdentityBifunctorized`. The Identity-typeclass instances +(`Parallel2[IdentityBifunctorized]`, `UnsafeRun2[IdentityBifunctorized]`, +`Temporal2[IdentityBifunctorized]`, `ApplicativeError2[IdentityBifunctorized]`) +delegate to MiniBIO's instances via `asInstanceOf`, and the user's +extraction is a separate explicit `debifunctorizeIdentity` call OR an +auto-applied implicit conversion at expected-type sites. + +The user-facing failure mode this enables: + +```scala +// Before M5 (worked because Identity[A] = A; eager): +class MyApp extends RoleAppMain[Identity] { + override def main: MainEffect[Unit] = Unit = { + Injector[Identity]().produceRun(...) + // produceRun returned `Unit` (== Identity[Unit] == A); side effects ran inline. + } +} + +// After M5 (silently broken): +class MyApp extends RoleAppMain[Bifunctorized.IdentityBifunctorized] { + override def main: MainEffect[Unit] = { + Injector[Bifunctorized.IdentityBifunctorized]().produceRun(...) + // Returns Bifunctorized.IdentityBifunctorized[Throwable, Unit] + // = MiniBIO[Throwable, Unit] (suspended) + // The value is DISCARDED (return type `Unit` triggers value-discard). + // The MiniBIO is never run. Side effects never execute. The role lifecycle + // never instantiates anything. Downstream `probe.locator.get[...]` NPEs. + } +} +``` + +The user-visible damage: silent eager → lazy switch at the `main` +entry point. No compile error (Scala's value-discard is silent in many +return-type positions), no runtime exception until the role's resources +are referenced. + +### Design options + +1. **Auto-run on debifunctorize at value-discard positions** — make the + implicit `debifunctorizeIdentityConversion` (or an analogous + `MainEffect[Unit]`-shaped sink) execute the MiniBIO at the conversion + seam. Hard to do robustly: Scala's value-discard machinery isn't a + normal implicit-conversion site, and forcing eager execution at + conversion violates the spec's invariant that `Bifunctorized[Identity, + ...]` is the MiniBIO-suspended form (Goal 3). + +2. **Force the user to `debifunctorizeIdentity` explicitly** — train + callers (and the migration guide) to wrap any `main`-style + `Identity`-typed body in `Bifunctorized.debifunctorizeIdentity(...)`. + Mechanical, no design surprise. Burden on the user. + +3. **Don't bifunctorize at the `RoleAppMain.main` boundary** — keep the + `main` method monofunctor-typed. The `RoleAppMain` trait would need + two variants (or a type parameter) to support both Identity-eager and + Bifunctorized-suspended bodies. Adds complexity at the framework + entry; preserves user expectations. + +4. **Redesign the M2 Identity bridge** — drop the MiniBIO suspension + for the Identity special case. Make `Bifunctorized.IdentityBifunctorized + [+E, +A]` equivalent to `Either[E, A]` at the runtime level (eager + carrier with a typed error channel). Preserves "Identity is eager". + Breaks the M2 "Identity gains lawful monadic suspension" design choice. + +5. **Hybrid**: keep MiniBIO suspension for the in-bifunctor-world ops, + but at the user-facing extraction seams (`MainEffect`, + `produceRun`'s return, etc.) auto-run. This requires identifying + the seams and providing dedicated extraction points (e.g. + `Injector.produceRunIdentity` that internally + `debifunctorizeIdentity`-s). + +The user invoking autonomous mode chose (autonomously) option 2 by +default. The framework-internal regressions documented below are the +consequences. A deliberate user decision could change the design. + +### Where this matters in code + +- `RoleAppMain.main` — discards the suspended `IdentityBifunctorized` result. +- `Producer.produceRun(plan)(f: Locator => F[Throwable, B])` — returns + `F[Throwable, B]`. For Identity this is a suspended MiniBIO; downstream + must run it. Currently runs only when the caller explicitly extracts. +- `RoleAppPlanner.Impl[F]`'s runtime-root set includes `Async2[F]` — + but `Async2[IdentityBifunctorized]` is intentionally not bound (sync + carrier). Pre-M5 used `Async1[Identity]` which was an unlawful no-op. +- `AppResourceProvider.Impl[F: TagKK: IO2: Primitives2]` / + `RoleAppEntrypoint.Impl[F: TagKK: Primitives2]` — class-level context + bounds that the BOOTSTRAP injector can't satisfy. Pre-M5 used `F[_]: + TagK` with no constraints and pulled typeclasses from `runtimeLocator` + at instantiation time. +- `TerminatingHandler` — calls `System.exit(1)` on uncaught role + failures. Kills the ScalaTest JVM mid-run. + +--- + +## Open question 1: 8 `RoleAppTest` failures (this fork's downstream consequence) + +`distage-frameworkJVM/test`: 11/19 pass; 8 fail in `RoleAppTest.scala`. +Confirmed at HEAD `148b84d63` and at earlier baselines (M5/10c). + +**Four distinct root causes**, all framework-internal regressions +caused by M5/10c: + +1. **`RoleAppMain.main` discards the lifecycle** (the fork above). + Wrapping the body in `Bifunctorized.debifunctorizeIdentity(...)` + makes it run, but exposes #2. + +2. **`AppResourceProvider.Impl` / `RoleAppEntrypoint.Impl` class-level + context bounds.** These are wired by `RoleAppBootModule` whose + injector is `IdentityBifunctorized`-flavored; + `IO2[Bifunctorized[IO, +_, +_]]` etc. are bound only in + `DefaultModule[F]`, consumed by the inner app injector. Bootstrap + injector can't satisfy them. + + Fix: drop the constraints and plumb `IO2`/`Primitives2`/`Async2` + through `runTasksAndRoles` parameters (or via a dedicated + `FrameworkSupportModule` that ports the inner module's typeclass + bindings into the bootstrap stage). + +3. **`Async2[Bifunctorized.IdentityBifunctorized]` is not bound** by + `IdentitySupportModule`. `RoleAppPlanner.Impl[F]` registers `DIKey + .get[Async2[F]]` as a runtime root unconditionally. Identity's + MiniBIO carrier has no `Async2` (sync-only). + + Fix options: + - Bind a stub `Async2[IdentityBifunctorized]` that throws on async + ops (matches the pre-M5 unlawful Identity behavior; lawless but + unblocks the planner). + - Make `RoleAppPlanner` register `Async2` as an OPTIONAL root and + fall back to `IO2` for sync-only carriers. + +4. **`TerminatingHandler` calls `System.exit(1)`** which kills the + ScalaTest JVM mid-run, masking the actual assertion failures of + tests that exercise role apps with uncaught faults. Pre-M5 the same + handler ran via `Identity[Unit]` whose `unit` was eager `()` — the + exit ran inline at the role app's natural completion, not from + inside a suspended MiniBIO that may never have been entered. + + Fix: replace `System.exit(1)` with a typed-error raise inside the + `F` carrier so the test harness can intercept it without killing + the JVM. Tests that DO assert on `System.exit` would need a + separate witness mechanism. + +These four fixes are independent but interact at the framework level. +A clean session-7 dispatch would tackle them in order #1 → #3 → #2 → #4, +verifying `RoleAppTest` 19/19 incrementally. + +--- + +## Open question 2: 3 ignored `CatsResourcesTestJvm` tests (M5-D01) + +`distage-coreJVM/test`: 396/399 (3 `ignore`).
