Type

  • Refactor
  • Feature
  • Bug Fix
  • Optimization
  • Documentation Update

Description

  • Avoid copying and filtering the entire context when Context.pick selects zero or one service.
  • Keep the existing behavior: return a new context without changing the original, preserve services whose value is undefined, and avoid creating default services during selection. Selecting multiple services follows the existing code path.
  • Extend existing tests to cover the fast paths and edge cases.

Benchmarks

  • Baseline: 35ec46e
  • Host: AMD Ryzen 5 5600 (12 logical CPUs), Windows x64 (10.0.26300).
  • Engines: Node 26.4.0, Bun 1.4.0 and Deno 2.9.4
  • Method: Compared the original and optimized code across 12 runs per engine, using contexts with 64 services.

@gchen0002
perf(Context): optimize pick for zero or one service
da64362 
Add fast paths for zero or one selected service using the existing lookup
and missing-value semantics.

Preserve fresh context/cache isolation and the existing multi-service
path. Extend existing tests with focused regression assertions and include
an effect patch changeset.

### Patch Changes

- [#9158](Effect-TS/effect#9158)
[`5951ac0`](Effect-TS/effect@5951ac0)
Thanks @<!---->fubhy! - Add typed connection options to `NodeHttpClient`
for unix sockets and mutual TLS.

- [#9136](Effect-TS/effect#9136)
[`12be65e`](Effect-TS/effect@12be65e)
Thanks @<!---->tim-smart! - Redact sensitive query values in HTTP spans,
request inspection and error messages. Also redact URL credentials in
client spans, request inspection and errors. Request URLs sent over the
wire are unchanged.
  
Move `AWSAccessKeyId`, `Signature`, `sig` and `X-Goog-Signature` from
`Headers.CurrentRedactedNames` to the new
`UrlParams.CurrentRedactedNames`. A custom list replaces these defaults.
Add `UrlParams.isRedactedName`, `UrlParams.redact` and
`UrlParams.redactUrl` for explicit redaction.

### Minor Changes

- 13a46c9: The `deterministicKeys` rule and the key completions now
compute a key for files without a `package.json`, or whose nearest
`package.json` has no `name`. The key is built as usual, but without the
package name. The sub-directory segment is relative to the
`package.json` directory if one is found, otherwise to the
`tsconfig.json` directory, otherwise to the program's common source
directory.
  
Projects that enabled `deterministicKeys` without a `package.json` will
now see reports. This differs from the upstream
`@effect/language-service`, which skips these files.
  
  ```json
  {
    "name": "@effect/language-service",
    "keyPatterns": [{ "target": "service", "pattern": "default" }]
  }
  ```
  
  ```ts
// src/services/AuthService.ts, no package.json, tsconfig.json at the
project root
  // reports: the expected key is `services/AuthService/MyService`
export class MyService extends Context.Service<MyService,
{}>()("MyService") {}
  ```
- d8c489b: Add `errorPayloadShadowsName` to detect inline `name` payload
fields on Effect error classes. For example,
`Data.TaggedError("ToolNotFound")<{ name: string }>` copies the
payload's `name` onto the error instance and hides the error type in
logs. Rename the field to `toolName`. The rule inspects inline payloads
only and allows a field whose value is the literal the error already
uses as its name.
- 13a46c9: Add an `"identifier"` pattern to `keyPatterns` for the
`deterministicKeys` rule. With it, the expected key is the class name
alone.
  
  ```json
  {
    "name": "@effect/language-service",
    "keyPatterns": [{ "target": "error", "pattern": "identifier" }]
  }
  ```
  
  ```ts
  // reports: the expected key is `KeybindingsConfigError`
export class KeybindingsConfigError extends
Data.TaggedError("KeybindingsConfigParseError")<{}> {}
  ```
- b1ed4ba: Add `preferNamespaceImport` and `preferBarrelImport`, two
diagnostics that report existing imports that contradict the import
style confi

### Minor Changes

- 3e4a55d: Route Effect contextual-type queries through
`TypeParser.GetContextualType` and enforce the wrapper with customlint.
For example, use `tp.GetContextualType(node, checker.ContextFlagsNone)`
instead of the checker method. Query behavior stays unchanged, with one
place to add contextual-type safety guards in future changes.
- 0269634: Add `effectSleepZeroToYieldNow`, a style suggestion with a
quick fix for zero-duration `Effect.sleep` calls.
  
For example, `Effect.sleep(0)` becomes `Effect.yieldNow()` in Effect v3
and `Effect.yieldNow` in Effect v4. The rule also recognizes safe
zero-duration strings, tuples, and Duration constructors. The
replacement yields through the fiber scheduler instead of the Clock
service.
- 181b2b3: Add the `flatMapToTap` style suggestion and quick fix for
Effect v3 and v4. Callbacks that run an effect and restore their
unchanged parameter with terminal `Effect.as` or `Effect.map` can use
`Effect.tap` instead. The fix preserves callback statements and earlier
effect transformations.
- 7d051dd: Route internal symbol and type location queries through
TypeParser and enforce this with customlint. Reuse the existing
TypeParser throughout pipeable signature comparison.
  
Prevent false TS2790 diagnostics for valid index-signature deletes such
as `declare const map: { [key: string]: number }; delete map.x;`. Symbol
queries skip deleted property accesses and their names, including
parenthesized and optional targets. Receiver and computed-key queries
remain available, and invalid required-property and readonly deletes
still report compiler errors.
- f178ff2: Add the opt-in `preferEffectArray` diagnostic in
`effectNative` for native Array method calls and references. It suggests
16 corresponding Effect Array APIs and explains migration differences,
such as `values.find(predicate)` becoming `Array.findFirst(values,
predicate)` with an `Option` result.
  
  The rule is disabled by default and enabled as a warning by the

single input's `previousSuccess` instead of the combined record or
tuple.

- [#9105](Effect-TS/effect#9105)
[`74d1930`](Effect-TS/effect@74d1930)
Thanks @<!---->tim-smart! - Fix infinite atom rebuilds caused by late
reads of uninitialized dependencies.

- [#9145](Effect-TS/effect#9145)
[`a03afb6`](Effect-TS/effect@a03afb6)
Thanks @<!---->jayhemnani9910! - Add `Flag.withOptionalValue` for
GNU-style flags with an optional value, like `--color[=WHEN]`. A bare
flag uses the given value; an explicit value must be attached with `=`.

- [#9131](Effect-TS/effect#9131)
[`f159284`](Effect-TS/effect@f159284)
Thanks @<!---->tim-smart! - Fix lost deferred callback wakes in cluster
workflows when an activity suspends while a parallel activity is still
running.

- [#9094](Effect-TS/effect#9094)
[`5d301cc`](Effect-TS/effect@5d301cc)
Thanks @<!---->okxint! - Name cluster entity RPC server spans by entity
type only (e.g. `WorkflowEntity.Run`) so span names stay
low-cardinality. The entity ID is still recorded in the `entity.id` span
attribute.

### Patch Changes

- [#9030](Effect-TS/effect#9030)
[`7547a99`](Effect-TS/effect@7547a99)
Thanks @<!---->effect-bot! - Bound sparse array indices in
`SchemaGetter.makeTreeRecord`, used by `Schema.fromURLSearchParams` and
`Schema.fromFormData`. An indexed container with more than 20 holes is
now returned as an object keyed by its index strings instead of a sparse
array, and appending after the maximum array index no longer throws.

- [#9083](Effect-TS/effect#9083)
[`711719d`](Effect-TS/effect@711719d)
Thanks @<!---->effect-bot! - Bound import-time stack detection probes to
the frames they inspect, restoring the caller's stack trace limit
afterward.

- [#9041](Effect-TS/effect#9041)
[`8f1ea52`](Effect-TS/effect@8f1ea52)
Thanks @<!---->tim-smart! - Stop grouped RequestResolvers from retaining
batch keys for the lifetime of the resolver. Equal keys are now matched
by the pending batch map, so a key is dropped as soon as its batch stops
pending, including after interruption.

- [#9010](Effect-TS/effect#9010)
[`c93485e`](Effect-TS/effect@c93485e)
Thanks @<!---->effect-bot! - Support an explicit client `servername` for
TLS socket upgrades without changing hostname behavior when omitted.

- [#8990](Effect-TS/effect#8990)
[`37e088f`](Effect-TS/effect@37e088f)
Thanks @<!---->bastiankistner! - Use decoded response aliases in
generated HTTP clients. Render bare numbers with a standard leading
finite check as `Schema.Finite`, preserving annotations and other
checks.

- [#8998](Effect-TS/effect#8998)
[`9314666`](Effect-TS/effect@93146666ec49cd6831e9c9d5fa0f9
