BREAKING CHANGE: some hot-path async members return ValueTask instead of Task; the reflection request builder is now the opt-in Refit.Reflection package; fully generated interfaces validate on first call, not in RestService.For; query objects flatten by declared type and honor the content serializer property names.

Interfaces whose methods all generate inline no longer touch +the reflection request builder at any point, which is what makes them trim and Native AOT clean — and that shift is +visible in three places. + +* **Some hot-path async members now return `ValueTask` instead of `Task`** (allocation reductions for the breaking + release). `ApiResponse.EnsureSuccessStatusCodeAsync()`/`EnsureSuccessfulAsync()` (and the matching + `IApiResponse` extension methods) and `DefaultApiExceptionFactory.CreateAsync` now return `ValueTask<...>`, making + their common success path allocation-free. The `RefitSettings` async delegates `ExceptionFactory`, + `DeserializationExceptionFactory`, and `AuthorizationHeaderValueGetter` now use `ValueTask`-returning `Func` shapes, + removing a per-request `Task` allocation from the default (synchronously-completing) exception factory. `async` + lambdas assigned to these delegates need no change; a delegate that returned `Task.FromResult(x)` should return + `new ValueTask(x)`, and a caller that stored an `EnsureSuccess...Async()` result as a `Task` should `await` it or + call `.AsTask()`. `TransportExceptionFactory` is unaffected (it was already synchronous). +* **The reflection request builder is now an opt-in package.** The `Refit` package no longer carries it. If any of + your interface methods cannot generate inline — the RF006 diagnostic reports exactly which — add a reference to the + [`Refit.Reflection`](https://www.nuget.org/packages/Refit.Reflection) package and everything works as before, with + no code changes. Without it, `RestService.For` and `AddRefitClient` throw a `NotSupportedException` naming the + package when they reach a method that needs reflection. Applications whose interfaces all generate inline should not + install it: that is what keeps a client trimmable and Native AOT clean. +* **Interface validation for fully generated interfaces happens when a request is built, not when the client is + created.** `RestService.For` still validates reflection-backed interfaces eagerly, but an interface whose methods + all generate inline never touches the reflection request builder — an invalid route template (for example a + placeholder with no matching parameter) now throws the same `ArgumentException` on the first call instead of inside + `RestService.For`. +* **`ApiException` stack traces no longer contain the generated method frame** for methods that construct requests + inline (they return the runner task directly instead of awaiting inside an async wrapper). Use + `ApiException.HttpMethod`/`ApiException.Uri` to identify the failing request. +* **Query objects are flattened by their declared type, not their runtime type.** A complex parameter whose public + properties become query pairs is now flattened at compile time, the same way the `System.Text.Json` source generator + treats a declared type. The reflection request builder called `value.GetType()`, so passing a *derived* instance + through a base-typed parameter also contributed the derived type's extra properties. Generated request building emits + only the properties declared on the parameter's type: + + ```csharp + public record BaseRecord(string Value); + public sealed record DerivedRecord(string Name) : BaseRecord("value"); + + [Get("/search")] + Task Search(BaseRecord query); + + Search(new DerivedRecord("ada")) + >>> "/search?Value=value" // V14, generated: declared type only + >>> "/search?Name=ada&Value=value" // V13, reflection: runtime type + ``` + + Only polymorphic query objects are affected; a parameter whose declared type is the type you actually pass is + unchanged. If you rely on the old behavior, declare the parameter as the derived type. + +* **Flattened query-object keys honor the content serializer's property names.** A query object's property keys now + resolve with the same precedence form-encoded field names already used: `[AliasAs]` first, then the configured + content serializer's field name (`[JsonPropertyName]` for the default `System.Text.Json` serializer, `[JsonProperty]` + for `Refit.Newtonsoft.Json`), then the URL parameter key formatter. Previously query keys consulted only `[AliasAs]` + and the key formatter, so a `[JsonPropertyName]` on a flattened property had no effect on the query string. + + ```csharp + public sealed class Filter + { + [JsonPropertyName("created_after")] + public DateTimeOffset? CreatedAfter { get; set; } + } + + [Get("/search")] + Task Search([Query] Filter filter); + + Search(new Filter { CreatedAfter = ... }) + >>> "/search?created_after=..." // V14: serializer field name + >>> "/search?CreatedAfter=..." // V13: CLR name + ``` + + Both request builders apply this. The generated path bakes the `[JsonPropertyName]` name at compile time (matching + the generated form path); the reflection path resolves it through the configured serializer, so it also picks up + `[JsonProperty]` when `Refit.Newtonsoft.Json` is installed. To keep the pre-V14 behavior, set + `RefitSettings.HonorContentSerializerPropertyNamesInQuery = false`; `[AliasAs]` still takes precedence in either mode. + +### New in V14.x + +* **Inline query-string generation.** Query parameters — auto-appended parameters, `[AliasAs]`, `[Query(Format = ...)]`, + and scalar collections with every `CollectionFormat` — now generate reflection-free request construction, so the most + common Refit method shapes work with generated-only clients (`AddRefitGeneratedClient`, `RestService.ForGenerated`) + and under Native AOT. Implicit body detection (a complex parameter on POST/PUT/PATCH without `[Body]`) generates + inline too, and value formatting for statically-known types (numbers, dates, GUIDs, enums with `[EnumMember]`) is + resolved at compile time while still honoring a custom `IUrlParameterFormatter` when one is configured. +* **Reflection-free query-object flattening.** A complex query parameter's public readable properties are now walked at + compile time and emitted as straight-line code — no reflection, no delegates, and no per-request descriptor array — + honoring `[AliasAs]`, the content serializer's property name (`[JsonPropertyName]`), `[Query]` + prefix/delimiter/format/`SerializeNull`, and the `IgnoreDataMember`/`JsonIgnore` attributes. Value-typed properties + are formatted without boxing. A property that is itself a collection of simple elements (for example `int[]`, + `List`, `IReadOnlyList`) flattens too, honoring its `CollectionFormat`; a customized + `IUrlParameterFormatter` still gets the reflection builder's two formatting passes. A property that is itself a + concrete nested object flattens recursively under a dotted key (`Address.City=...`), composing each level through the + key formatter and honoring per-level `[Query(Prefix)]`; a self-referential (cyclic) type keeps using the reflection + builder. See the declared-type and property-name notes above. +* **Reflection-free dictionary query parameters.** `IDictionary` and `Dictionary` with + simple keys and values expand inline, one query pair per entry, with the same semantics as before: entries with a + null value are omitted, blank keys drop the pair, enum keys render through `[EnumMember]`, and a parameter-level + `[Query(Prefix)]` is prepended to every key. Dictionaries with `object` values still use the reflection request + builder, because the value's runtime type decides whether it is recursed into — unless you attach an + `[QueryConverter]` (below). +* **`[QueryConverter]` for shapes only known at runtime.** Attach `[QueryConverter(typeof(MyConverter))]` to a query + parameter whose shape the generator cannot flatten from the declared type — an `object` value, a polymorphic base + type, a `Dictionary`. The converter (`IQueryConverter`) writes query pairs directly into the + pooled `GeneratedQueryStringBuilder`, so the parameter generates inline and stays reflection- and allocation-free. + It is a source-generation-only feature (like `[QueryName]`/`[Encoded]`): a method that carries it but cannot generate + inline for another reason reports `RF007`. The reflection request builder is unaffected; it keeps walking the runtime + type. `Refit` ships `SystemTextJsonQueryConverter`, which flattens any type registered in your configured + `System.Text.Json` context by walking its `JsonTypeInfo`. +* **`[QueryName]` valueless query flags.** The equivalent of Retrofit's `@QueryName`: the parameter's value becomes a + bare `?flag` segment with no `=value`; collections render one flag per element. See + [Valueless query flags](../README.md#valueless-query-flags). +* **`[Encoded]` per-parameter encoding opt-out.** The equivalent of Retrofit's `encoded = true`: a query or path value + (including round-tripping `{**param}` segments) passes through verbatim so pre-encoded values are not double-encoded. + See [Unescape Querystring parameters](../README.md#unescape-querystring-parameters). +* **RF006 fallback analyzer.** Methods that must use the reflection request builder are reported at compile time, so + generated-only and Native AOT clients fail the build instead of throwing at runtime. RF007 reports the use of + source-generation-only attributes (`[QueryName]`, `[Encoded]`) on methods that cannot generate inline. +* **Generated fallback methods no longer leak IL2026/IL3050.** Projects with `EnableTrimAnalyzer` and warnings as + errors build cleanly; the compile-time RF006 diagnostic is the signal that a method still needs reflection. +* **Hot-path allocation reductions.** The response pipeline avoids a per-stream linked `CancellationTokenSource` when a + token can't cancel, uses `HttpHeaders.NonValidated` for generated header checks (no value re-parsing), and returns + `ValueTask` from the internal deserialization chain so empty/`204` responses complete without a `Task` allocation — + alongside the public `ValueTask` moves noted in the breaking changes above. +* **Generic interface methods generate inline.** A generic Refit method (for example `Task Get(string id)` or + `Task Post([Body] TRequest body)`) no longer falls back to the reflection request + builder — the type parameter flows straight through to the generated runner (`SendAsync`), so generic + methods are reflection-free and Native AOT clean, with their generic constraints preserved. The narrow exceptions that + still require the reflection builder are the ones an *open* type parameter genuinely can't generate: a complex query + object (its query pairs are only known per value) and a form-url-encoded `[Body]` (its `[DynamicallyAccessedMembers]` + contract can't be satisfied by an open type parameter). RF006 continues to report exactly which methods still fall + back. +* **Pluggable return-type adapters (`IReturnTypeAdapter`).** Surface any custom return type (for + example `IObservable` or a `Result` wrapper) from an interface method by implementing the interface. The source + generator discovers adapters declared in your project at compile time and emits a direct `Adapt` call — no reflection, + so adapter-backed methods stay trim and Native AOT clean; the reflection request builder resolves adapters registered + in `RefitSettings.ReturnTypeAdapters`. See [Custom return types](../README.md#custom-return-types-ireturntypeadapter). + +## V13.x.x + +### Breaking changes in V13.x + +Refit 13 hardens the default security posture from a security audit. The new behavior is safe by default; the changes +below only affect code that previously relied on the less-secure defaults. + +* **XML responses no longer process DTDs.** `XmlContentSerializer` now forces `DtdProcessing.Prohibit` and clears the + `XmlResolver` on every read, blocking XML External Entity (XXE) and entity-expansion ("billion laughs") attacks. If + you were deserializing trusted XML that depends on a DTD or external entities, that content will now throw. We + **strongly recommend against re-enabling DTD processing**, but if your XML comes from a fully trusted source you can + opt out via the obsolete `XmlReaderWriterSettings.AllowDtdProcessing` flag (marked `[Obsolete]` deliberately, so it + surfaces a compiler warning) - you must also configure `DtdProcessing`/`XmlResolver` yourself on `ReaderSettings`. + Prefer pre-processing untrusted documents instead. +* **Newtonsoft.Json no longer inherits an unsafe global `TypeNameHandling`.** When you do not pass explicit + `JsonSerializerSettings`, `NewtonsoftJsonContentSerializer` now forces `TypeNameHandling.None` even if + `JsonConvert.DefaultSettings` configured a different value, closing a known remote-code-execution gadget vector on + response bodies. If you genuinely need polymorphic (`$type`) deserialization, opt in explicitly by passing your own + `JsonSerializerSettings` (ideally constrained with a `SerializationBinder`). + +The release also adds two opt-in, non-breaking knobs on `RefitSettings` for hardening exception handling: + +* `RefitSettings.ExceptionRedactor` — a hook invoked before an `ApiException` propagates, so you can scrub the + `Authorization` header, request/response bodies, and `Set-Cookie` before they reach logging or telemetry pipelines + that serialize exceptions. +* `RefitSettings.MaxExceptionContentLength` — caps how many characters of an error response body are read into + `ApiException.Content`, bounding memory use against hostile or oversized error responses. Defaults to unbounded. + +### New in V13.x + +* **`Refit.Testing`** — a new first-party package for testing Refit clients without a mocking library or a live + server. You describe expected calls as a route table (`Route` → `Reply`) and point a real client at it via + `StubHttp.CreateClient(...)`. Route templates mirror your interface attributes, typed replies (`Reply.With`) + are serialized with the client's own serializer, and the sent request body can be read back as a typed object with + `LastRequestBodyAsync()`. It also includes `NetworkBehavior` for seeded latency/fault injection and + `StubApiResponse` for unit-testing code that consumes `IApiResponse`. See + [Testing your Refit clients](../README.md#testing-your-refit-clients). +## V12.x.x + +### Breaking changes in V12.x + +Refit 12.0 is a large release centered on a near-complete rewrite of request building. The source generator now builds +eligible HTTP requests inline at compile time instead of going through the reflection request-builder pipeline, with the +reflection path kept as a fallback for shapes that cannot be generated inline. + +Two breaking changes are called out for migration: + +* `IApiResponse` no longer shadows base interface members. The `new`-shadowed `Error`, `ContentHeaders`, + `IsSuccessStatusCode`, and `IsSuccessful` members were removed from the generic interface. Source that reads these + members still binds to the inherited base members, but assemblies compiled against v8-v11 should be recompiled. + If you used `IsSuccessful` to narrow `Content` to non-null on an `IApiResponse` value, use `HasContent` or + `IsSuccessfulWithContent` instead. +* The default `System.Text.Json` serializer now reads numbers from JSON strings by setting + `JsonNumberHandling.AllowReadingFromString`. To opt back out, set `NumberHandling = JsonNumberHandling.Strict` on + your `JsonSerializerOptions`. + +See the [Refit 12.0.0 release notes](https://github.com/reactiveui/refit/releases/tag/v12.0.0) for the full release +details. + +## V11.x.x + +### Breaking changes in 11.x + +Refit 11 introduces `ApiRequestException` to represent requests that fail before receiving a response from the server. +This exception will now wrap previous exceptions such as `HttpRequestException` and `TaskCanceledException` when they +occur during request execution. + +* If you were not wrapping responses with `IApiResponse` and were catching these exceptions directly, you will need to + update your code to catch `ApiRequestException` instead. +* If you were wrapping responses with `IApiResponse`, these exceptions will no longer be thrown and will instead be + captured in the `IApiResponse.Error` property. + You can use the new `IApiResponse.HasRequestError(out var apiRequestException)` method to safely check and retrieve + the `ApiRequestException` instance. + +The `IApiResponse.Error` property's type has also changed to `ApiExceptionBase`, which is the new base class for +`ApiException` and `ApiRequestException`. +If your code accessed members specific to `ApiException` (i.e. anything related to the response from the server), you +can use the new `IApiResponse.HasResponseError(out var apiException)` method to safely check and retrieve the +`ApiException` instance. + +All response-related properties of `IApiResponse` are now nullable. +The new `IApiResponse.IsReceived` property can be used to check if a response was received from the server, and will +mark those properties as non-null. +The original `IApiResponse.IsSuccessful` and `IApiResponse.IsSuccessStatusCode` properties can still be used to check if +the response was received and is successful. + +## Updates in 8.0.x + +Fixes for some issues experienced, this led to some breaking changes. +See [Releases](https://github.com/reactiveui/refit/releases) for full details. + +## V6.x.x + +Refit 6 requires Visual Studio 16.8 or higher, or the .NET SDK 5.0.100 or higher. It can target any .NET Standard 2.0 +platform. + +Refit 6 does not support the old `packages.config` format for NuGet references (as they do not support analyzers/source +generators). You must +[migrate to PackageReference](https://devblogs.microsoft.com/nuget/migrate-packages-config-to-package-reference/) to use +Refit v6 and later. + +### Breaking changes in 6.x + +Refit 6 +makes [System.Text.Json](https://docs.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-overview) the +default JSON serializer. If you'd like to continue to use `Newtonsoft.Json`, add the `Refit.Newtonsoft.Json` NuGet +package and set your `ContentSerializer` to `NewtonsoftJsonContentSerializer` on your `RefitSettings` instance. +`System.Text.Json` is faster and uses less memory, though not all features are supported. +The [migration guide](https://docs.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-migrate-from-newtonsoft-how-to?pivots=dotnet-5-0) +contains more details. + +`IContentSerializer` was renamed to `IHttpContentSerializer` to better reflect its purpose. Additionally, two of its +methods were renamed, `SerializeAsync` -> `ToHttpContent` and `DeserializeAsync` -> `FromHttpContentAsync`. +Any existing implementations of these will need to be updated, though the changes should be minor. + +##### Updates in 6.3 + +Refit 6.3 splits out the XML serialization via `XmlContentSerializer` into a separate package, `Refit.Xml`. This +is to reduce the dependency size when using Refit with Web Assembly (WASM) applications. If you require XML, add a +reference +to `Refit.Xml`. + diff --git a/src/Directory.Build.props b/src/Directory.Build.props index 71e0e048f..ca23c9c16 100644 --- a/src/Directory.Build.props +++ b/src/Directory.Build.props @@ -158,7 +158,7 @@ minor alpha.0 v - 10.2 + 14.0 diff --git a/src/Directory.Packages.props b/src/Directory.Packages.props index 0ba8b41ff..9538ef0ce 100644 --- a/src/Directory.Packages.props +++ b/src/Directory.Packages.props @@ -9,7 +9,7 @@ 1.58.0 - 3.17.7 + 3.17.9 diff --git a/src/InterfaceStubGenerator.Shared/DiagnosticDescriptors.cs b/src/InterfaceStubGenerator.Shared/DiagnosticDescriptors.cs index 6595682a5..b301d732c 100644 --- a/src/InterfaceStubGenerator.Shared/DiagnosticDescriptors.cs +++ b/src/InterfaceStubGenerator.Shared/DiagnosticDescriptors.cs @@ -19,6 +19,18 @@ internal static class DiagnosticDescriptors DiagnosticSeverity.Error, true); + /// Diagnostic reported when a source-generation-only attribute is used on a method that cannot generate inline. + [System.Diagnostics.CodeAnalysis.SuppressMessage("Usage", "RS2008", Justification = "Diagnostic IDs are stable and intentionally not tracked in an analyzer release-tracking file.")] + public static readonly DiagnosticDescriptor SourceGenOnlyAttributeRequiresInlineRequest = + new( + "RF007", + "Attribute requires generated request building", + "Method '{0}' uses [{1}], which is only honored by generated request building, but its request cannot be " + + "generated inline.

Measured on a 60-interface corpus: per-keystroke and cold-build allocations both down ~17-18%.

Flatten nullable nested value-type (Nullable) query-object properties inline, unwrapping to the underlying struct and accessing via .Value. - Generate an inline Authorization header for [Authorize] parameters using the compile-time scheme; multiple [Authorize] falls back so it still throws. - Flatten dictionary properties inside a query object inline, expanding entries under the property key. - Generate non-[Encoded] round-trip {**param} catch-all paths of any type inline via GeneratedRequestRunner.RoundTripEscapePath. -

An unsupported residual property shape still falls the whole parameter back. - Sort path replacements by template position before emitting. The runtime BuildRequestPath overloads slice between consecutive placeholders, so an object binding filling an earlier placeholder than a later parameter threw ArgumentOutOfRange in the parameter-precedence case. - Cover the feature with a live reflection-parity test (generated URI equals the reflection builder) and a PathObjectBindingGenerationTests file spanning inline, residual-inline and unsupported-residual fallback. - Upgrade StyleSharp/PerformanceSharp analyzers to 3.19.0 and satisfy the new rules without suppressions or editorconfig changes: name repeated test literals, seal the top-level Program types, return a cached read-only view from StubHttp.Requests, and scope the SST1472 case to the tested constructor. --- src/Directory.Packages.props | 2 +- .../Emitter.Inline.Query.cs | 92 ++++++-- .../Emitter.Inline.cs | 123 +++++++++-- .../InterfaceStubGeneratorV2.cs | 6 +- .../Models/KnownTypeConstraint.cs | 2 +- .../Models/PathObjectBindingModel.cs | 18 ++ .../Models/RequestParameterModel.cs | 5 + .../Parser.Request.Path.cs | 201 ++++++++++++++++++ .../Parser.Request.Query.cs | 8 +- .../Parser.Request.cs | 15 +- .../Refit.Analyzers.Roslyn48.csproj | 2 + .../Refit.Analyzers.Roslyn50.csproj | 2 + src/Refit.NativeAotSmoke/Program.cs | 9 + src/Refit.Testing/StubHttp.cs | 30 ++- src/Refit/ApiException.cs | 3 + src/benchmarks/Refit.Benchmarks/Program.cs | 9 + src/examples/BlazorWasmIssue2065/Program.cs | 9 + .../Refit.CodeFixes.Tests/CodeFixFixture.cs | 9 +- .../Refit.GeneratorTests/ExternAliasTests.cs | 9 +- .../GeneratedCodeComplianceTests.cs | 9 +- .../GeneratedRequestBuildingTests.cs | 28 --- .../GeneratorComponentTests.cs | 34 ++- .../PathObjectBindingGenerationTests.cs | 104 +++++++++ .../QueryRequestBuildingLiveTests.cs | 69 ++++-- .../RestServiceIntegrationTests.GitHub.cs | 9 +- ...RestServiceIntegrationTests.RequestBody.cs | 15 +- .../StubHttpCoverageTests.cs | 9 +- .../Refit.Testing.Tests/StubHttpTests.cs | 18 +- src/tests/Refit.Tests/ApiExceptionTests.cs | 13 +- src/tests/Refit.Tests/ApiResponseTests.cs | 18 +- .../AuthenticatedClientHandlerTests.cs | 9 +- .../DefaultInterfaceMethodTests.cs | 9 +- .../DeserializationExceptionFactoryTests.cs | 9 +- .../ExplicitInterfaceRefitTests.cs | 9 +- .../Refit.Tests/FormValueMultimapTests.cs | 36 ++-- .../GeneratedRequestRunnerTests.cs | 41 ++-- .../HttpClientFactoryExtensionsTests.cs | 18 +- src/tests/Refit.Tests/MultipartTests.cs | 30 ++- .../RequestBuilderTests.Dictionaries.cs | 9 +- .../RequestBuilderTests.Queries.cs | 36 ++-- src/tests/Refit.Tests/RequestBuilderTests.cs | 30 ++- src/tests/Refit.Tests/ResponseTests.cs | 18 +- ...RestServiceIntegrationTests.Inheritance.cs | 45 ++-- ...RestServiceIntegrationTests.RequestBody.cs | 37 ++-- .../RestServiceIntegrationTests.cs | 65 ++++-- .../Refit.Tests/SerializedContentTests.cs | 18 +- .../Refit.Tests/StreamingResponseTests.cs | 18 +- 47 files changed, 1014 insertions(+), 303 deletions(-) create mode 100644 src/InterfaceStubGenerator.Shared/Models/PathObjectBindingModel.cs create mode 100644 src/InterfaceStubGenerator.Shared/Parser.Request.Path.cs create mode 100644 src/tests/Refit.GeneratorTests/PathObjectBindingGenerationTests.cs diff --git a/src/Directory.Packages.props b/src/Directory.Packages.props index 9538ef0ce..37073c5d6 100644 --- a/src/Directory.Packages.props +++ b/src/Directory.Packages.props @@ -9,7 +9,7 @@ 1.58.0 - 3.17.9 + 3.19.0 diff --git a/src/InterfaceStubGenerator.Shared/Emitter.Inline.Query.cs b/src/InterfaceStubGenerator.Shared/Emitter.Inline.Query.cs index 34bdb9ba9..61fdf731f 100644 --- a/src/InterfaceStubGenerator.Shared/Emitter.Inline.Query.cs +++ b/src/InterfaceStubGenerator.Shared/Emitter.Inline.Query.cs @@ -26,6 +26,15 @@ internal static partial class Emitter /// The start of a generated foreach (var …) loop over a collection or dictionary. private const string ForeachVarKeyword = "foreach (var ";

Query URIs stay byte-identical. - Add GeneratedQueryStringBuilder.AddFormatted / AddCollectionValueFormatted (net6+): TryFormat into a stack buffer, append URL-unreserved integers verbatim and span-escape other values (net9+), matching Add/AppendPair. - Emit the fast call on the default-formatting branch for span-formattable values, reusing the parser's IsUrlSafeSpanFormattable / IsSpanFormattableEscapable tiers; customized-formatter, TreatAsString, enum and string paths are unchanged. - Extract the enum/converter formatter helpers into a new partial file to keep Emitter.Inline.Query.cs within the file-length limit. - Cover int/long scalars, a formatted double, int Csv/Multi collections and a null nullable int in the reflection-parity live suite. --- .../Emitter.Inline.Query.Formatters.cs | 114 ++++++++ .../Emitter.Inline.Query.cs | 250 ++++++++---------- src/Refit/GeneratedQueryStringBuilder.cs | 121 +++++++++ .../PublicAPI/net10.0/PublicAPI.Unshipped.txt | 2 + .../PublicAPI/net11.0/PublicAPI.Unshipped.txt | 2 + .../PublicAPI/net8.0/PublicAPI.Unshipped.txt | 2 + .../PublicAPI/net9.0/PublicAPI.Unshipped.txt | 2 + .../QueryRequestBuildingLiveTests.cs | 7 + 8 files changed, 360 insertions(+), 140 deletions(-) create mode 100644 src/InterfaceStubGenerator.Shared/Emitter.Inline.Query.Formatters.cs diff --git a/src/InterfaceStubGenerator.Shared/Emitter.Inline.Query.Formatters.cs b/src/InterfaceStubGenerator.Shared/Emitter.Inline.Query.Formatters.cs new file mode 100644 index 000000000..85a10a095 --- /dev/null +++ b/src/InterfaceStubGenerator.Shared/Emitter.Inline.Query.Formatters.cs @@ -0,0 +1,114 @@ +// Copyright (c) 2019-2026 ReactiveUI and Contributors.

19fca3212422e98821b55f906054f36d9b6b2686 Mon Sep 17 00:00:00 2001 From: Glenn Watson <5834289+glennawatson@users.noreply.github.com> Date: Tue, 14 Jul 2026 01:13:12 +1000 Subject: [PATCH 76/85] test: cover source-generated request building to 100% - Add runtime, generator, and reflection tests bringing every file touched by the reflection-free request-building feature to 100% line coverage. - Remove dead code surfaced by the coverage push: inline FindHttpMethodProperty so its unreachable return null folds into the covered fallback, drop the dead PropertyDeclarationSyntax getter arm, and delete the redundant adapter bounds guard (the source-generated binder indexes the same slots without one). - Bump StyleSharp/PerformanceSharp to 3.21.2, SonarAnalyzer.CSharp to 10.29.0.143774, TUnit to 1.59.0, Verify.TUnit to 31.24.1, and Serilog to 4.4.0; the analyzer update clears the SonarCloud SST2015/SST1462 build errors. --- src/Directory.Packages.props | 10 +-

compliance - Split oversized files into behavior-named partial classes and extract long methods (SST1522/SST1523) across Refit.Reflection, Refit.Testing, and the test and benchmark projects. - Fix mechanical findings: buried ++/-- (SST2015), numeric-suffix casing (SST2244), redundant interface public (SST1491), replaceable collections (SST2305), per-call serializer options (PSH1416), and assorted others. - Suppress the few genuinely-unfixable findings with justifications: CS0501- mandated abstract on an explicit-interface re-abstraction, options capturing a per-call resolver, the interface-dispatch and sync-stream test surfaces, and the BCL-mirror [Flags] enum polyfill. - Behavior unchanged; the full solution builds analyzer-clean and all tests pass. ---

test: cover reachable branches across the touched surface - Add branch-covering tests across the generator, runtime, reflection, testing, analyzer and code-fix files, closing 74 of the 125 partial/uncovered branches flagged on the touched files. - Drive the real generated/parsed and reflection request-building surface for each untested condition outcome (attribute combos, param/return shapes, dotted paths, query objects, dictionaries, multipart parts, custom verbs, adapters, RFC-3986 escaping, cancellation linking, and error/fallback paths). - The remaining 51 branches are provably unreachable (compiler-generated string jump tables, dead null-conditionals on never-null operands, exhaustive switch defaults, async-iterator dispose-mode IL edges, contract-guaranteed non-null). ---
