Root cause: `formatCustomOptions` only quotes keys containing `.` or starting with a digit, but doesn't check for other special chars. The TS `typescriptLiteralFromValue` uses regex `/^(?![0-9])[a-zA-Z0-9$_]+$/` to decide quoting.

So a string like `"hello\vworld"` is emitted correctly by TS but the Go plugin emits the raw 0x0B byte. Root cause: incomplete string escaping in `formatCustomOptions`.

Root cause: `findMessageType` only searched direct dependencies, not all files. Fixed by RALPH. Tested in `239_wkt_custom_option`. - **Hyphenated json_name in custom option messages** — When a message used as a custom option value has fields with `json_name` containing non-identifier characters (hyphens, spaces, etc.), the Go plugin emits the key unquoted (`my-value: ...`) while TS quotes it (`"my-value": ...`). Root cause: `formatCustomOptions` only quotes keys containing `.` or starting with a digit, but doesn't check for other special chars.

This is a subtlety of the fix. - Same repeated-extension-single bug likely applies to repeated enum, repeated int32, repeated bytes, repeated message top-level extensions with a single value — all go through `parseCustomOptions` which lacks wrapping. - Same integer-key ordering issue applies to `map`, `map`, `map`, etc. — all numeric map key types would have JS Object.keys() reordering. But RALPH will likely fix all at once. - Bool map keys in custom options: TS may order `false` before `true` (since `Object.keys` on `{true: ..., false: ...}` preserves insertion order for non-integer keys). Check if wire order `true, false` matches TS order. diff --git a/protoc-gen-kaja/tests/253_custom_option_string_nonascii/options.proto b/protoc-gen-kaja/tests/253_custom_option_string_nonascii/options.proto new file mode 100644 index 00000000..1f753893 --- /dev/null +++ b/protoc-gen-kaja/tests/253_custom_option_string_nonascii/options.proto @@ -0,0 +1,8 @@ +syntax = "proto2"; +package test; + +import "google/protobuf/descriptor.proto"; + +extend google.protobuf.FieldOptions { + optional string label = 50001; +} diff --git a/protoc-gen-kaja/tests/253_custom_option_string_nonascii/test.proto b/protoc-gen-kaja/tests/253_custom_option_string_nonascii/test.proto new file mode 100644 index 00000000..fc84f072 --- /dev/null +++ b/protoc-gen-kaja/tests/253_custom_option_string_nonascii/test.proto @@ -0,0 +1,10 @@ +syntax = "proto3"; +package test; + +import "options.proto"; + +// Tests that non-ASCII characters in custom option string values +// are escaped as \uXXXX (matching TypeScript printer's escapeNonAsciiString). +message TestMsg { + string name = 1 [(label) = "café"]; +} From 09c8bf133fb015144d0ab4d0f9dc33d6c083384d Mon Sep 17 00:00:00 2001 From: tom-newotny Date: Sat, 21 Feb 2026 16:53:09 -0800 Subject: [PATCH 032/102] Escaped all non-ASCII characters (>= 0x80) in JS string literals Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- protoc-gen-kaja/RALPH.md | 7 ++++++- protoc-gen-kaja/main.go | 8 ++++++-- 2 files changed, 12 insertions(+), 3 deletions(-) diff --git a/protoc-gen-kaja/RALPH.md b/protoc-gen-kaja/RALPH.md index f9473f28..98ab64ae 100644 --- a/protoc-gen-kaja/RALPH.md +++ b/protoc-gen-kaja/RALPH.md @@ -72,6 +72,11 @@ You are running inside an automated loop. **Each invocation is stateless** — y - [x] Fix DEL character escaping in JS strings (test 251_custom_option_string_del) - Changed C1 range from `r >= 0x7F` to `r >= 0x80` — DEL (0x7F) is NOT escaped by TypeScript's printer - C1 control characters are 0x80–0x9F; DEL is technically a control char but TS passes it through literally +- [x] Fix non-ASCII character escaping in JS strings (test 253_custom_option_string_nonascii) + - Changed condition from specific ranges `(r >= 0x80 && r <= 0x9F) || r == 0x2028 || r == 0x2029 || r == 0xFEFF` to `r >= 0x80` + - TypeScript's printer uses `escapeNonAsciiString` which escapes ALL chars outside 0x0000-0x007F range + - Regex `/[^\u0000-\u007F]/g` means 0x7F (DEL) is NOT escaped but 0x80+ ALL are + - Added `\u{X}` format for supplementary chars (> U+FFFF) to match TS behavior ## Notes @@ -80,4 +85,4 @@ You are running inside an automated loop. **Each invocation is stateless** — y - Results are in `protoc-gen-kaja/results//`.

But the Go plugin's `isDefaultValue` function doesn't distinguish between required and optional — it unconditionally filters all default values. So `{ count: 0, label: "" }` is emitted by TS but becomes `{}` in Go. Root cause: `isDefaultValue` needs to check whether the field is proto2 optional (or proto3 explicit optional) before filtering defaults. For optional/explicit-optional fields, defaults should NOT be filtered. Only proto3 implicit non-optional fields and proto2 required fields should have defaults omitted. Fix: `isDefaultValue` (or its caller in `parseMessageValue`) must look at `fd.GetLabel()` and the file syntax to decide whether to skip defaults. Tested in `258_optional_default_option`. +- **google.protobuf.NullValue enum in custom option message** — The TS runtime's `ReflectionJsonWriter.enum()` has special handling for `google.protobuf.NullValue`: when `type[0] == 'google.protobuf.NullValue'`, it returns JSON `null` (not the enum value name string). So a proto2 optional `NullValue` field set to `NULL_VALUE` (value 0) outputs `nullField: null` in TS. The Go plugin has no NullValue-specific logic in `resolveEnumValueName` or `formatCustomOptions` — it resolves the enum name "NULL_VALUE" and outputs it as a quoted string `nullField: "NULL_VALUE"`. Root cause: `parseMessageValue` and `formatCustomOptions` don't know about NullValue's special JSON semantics.

TS escapes it via regex `\u0085` in `doubleQuoteEscapedCharsRegExp`. Go misses it because 0x85 > 0x20. Fix: add `r == 0x0085` check in `escapeStringForJS`. - **Hex digit casing in \uXXXX escapes applies broadly**: ANY character escaped via the `default` case in `escapeStringForJS` that has A-F hex digits will have lowercase vs uppercase mismatch. This includes: 0x80-0x9F range (C1 codes), 0xFEFF (BOM), and potentially any future additions. After RALPH fixes `%04x` → `%04X`, this class of bugs goes away. But also check `\x00` — does Go use `\x00` (lowercase) while TS uses `\x00` (also lowercase)? Verified: both use lowercase for `\x` escapes, so no issue there. - Wrapper types (Int32Value, BoolValue, etc.) as custom option types — tested, NO difference (TS plugin uses generic MessageType not WKT-aware toJson for options) -- Custom options with `google.protobuf.Any`, `google.protobuf.Struct`, `google.protobuf.Value` as the option type +- Custom options with `google.protobuf.Any`, `google.protobuf.Struct`, `google.protobuf.Value` as the option type — Struct/Value fields would use generic reflection toJson in TS (NOT WKT-specific), so no special handling difference. But NullValue IS handled specially by TS runtime (see exploit above). Any other WKTs that `ReflectionJsonWriter` gives special treatment? Check `google.protobuf.Duration`, `google.protobuf.Timestamp`, `google.protobuf.FieldMask` — the `message()` method calls `type.internalJsonWrite()` which may use WKT-specific formatting if the MessageType was set up with WKT extensions. But the interpreter creates plain MessageTypes without WKT extensions, so probably no difference. - Custom options with `google.protobuf.FieldMask`, `google.protobuf.Empty` as option types - Custom oneof-level options (`OneofOptions` extensions) - Extension field info generation for proto2 `extend` blocks diff --git a/protoc-gen-kaja/status.txt b/protoc-gen-kaja/status.txt index c8e8a135..7d68d91d 100644 --- a/protoc-gen-kaja/status.txt +++ b/protoc-gen-kaja/status.txt @@ -1 +1 @@ -DONE +HAHA diff --git a/protoc-gen-kaja/tests/259_custom_option_null_value/test.proto b/protoc-gen-kaja/tests/259_custom_option_null_value/test.proto new file mode 100644 index 00000000..20e1fdab --- /dev/null +++ b/protoc-gen-kaja/tests/259_custom_option_null_value/test.proto @@ -0,0 +1,26 @@ +syntax = "proto2";

The Go plugin ignores jstype on map fields entirely — `getBaseTypescriptType` for map value fields doesn't check the parent field's jstype, and the field info generation for maps doesn't add `L` to the V object. Root cause: multiple places in the Go plugin handle int64 jstype for regular scalar fields but skip map value fields: `getBaseTypescriptType` (called for map values via `getTypescriptType`), field info generation (line 4338-4341), binary read map helper, and binary write map helper.

So when a oneof string is set to `""`, int32 to `0`, or bool to `false`, the value IS included in the JSON output. The Go plugin's `isDefaultValue` filtering checks `hasPresence = fd.GetProto3Optional()` for proto3, which returns `false` for oneof fields (they're not proto3_optional). So it filters out the default-valued oneof field, producing `{}` instead of `{ text: "" }`. Root cause: `parseMessageValue`'s default-value filtering doesn't account for proto3 oneof fields needing their defaults emitted. Fix: when checking `hasPresence`, also check if the field is part of a oneof (`fd.OneofIndex != nil` and not synthetic/proto3_optional) — oneof members with explicit values always have presence.

With JS_NORMAL, bigint values need different serialization than string values. - **Non-ASCII escaping applies EVERYWHERE strings appear**: The `escapeNonAsciiString` is used by the TS printer for ALL string literals, not just custom options. This means `json_name` values (line 4285: `escapeStringForJS(actualJsonName)`) with non-ASCII chars would also differ.

The TS plugin's `reflectionCreate` sets properties in field number order; `Object.entries(defaultMessage)` returns the property at its FIRST creation position (from field 1) even though its value was overwritten by field 3. So the order is `x1Y, middle`. The Go plugin's dedup logic (lines 4693-4710) iterates in reverse and keeps the LAST occurrence, preserving the last item's position. So it outputs `middle, x1Y`. Root cause: The dedup keeps the LAST occurrence at the LAST position, but JS `Object.entries` returns a property at its FIRST creation position.

The TS plugin's `reflectionCreate` sets properties in field number order; `Object.entries(defaultMessage)` returns the property at its FIRST creation position (from field 1) even though its value was overwritten by field 3. So the order is `x1Y, middle`. The Go plugin's dedup logic (lines 4693-4710) iterates in reverse and keeps the LAST occurrence, preserving the last item's position. So it outputs `middle, x1Y`. Root cause: The dedup keeps the LAST occurrence at the LAST position, but JS `Object.entries` returns a property at its FIRST creation position. Fix: After dedup, the property should be placed at the position of the FIRST field that created it, not the last.

The Go plugin has no knowledge of this special exclusion — it discovers the extension normally via `buildExtensionMap` and includes it in the output. So when a service has `option (ts.client) = GENERIC_CLIENT`, TS outputs `new ServiceType("test.MySvc", [...])` (no service options) while Go outputs `new ServiceType("test.MySvc", [...], { "ts.client": ["GENERIC_CLIENT"] })`. Root cause: Go plugin's `getCustomServiceOptions` doesn't filter out protobuf-ts internal extensions. Fix: either hardcode exclusion of extensions from the `ts` package, or skip extensions with field numbers in the protobuf-ts reserved range (777701+), or check if the extension's package is `ts`.

**`ts.exclude_options` file option not implemented** — The TS plugin's `getMessageType()` reads `ts.exclude_options` from the file's `FileOptions` (extension field 777701 in package `ts`) and passes the values to `readOptions()`, which filters out matching custom option keys from field info and message options. The Go plugin has no knowledge of `ts.exclude_options` — it includes all custom options unconditionally. So when a file has `option (ts.exclude_options) = "test.my_tag"` and a field has `[(my_tag) = "important"]`, TS omits the option from the field info while Go includes `options: { "test.my_tag": "important" }`. Root cause: Go plugin never reads `ts.exclude_options` from `FileOptions` and never filters custom options by it. Fix: read `ts.exclude_options` from the file's unknown fields (same technique as `buildExtensionMap`), then filter custom options in `getCustomFieldOptions`, `getCustomMessageOptions`, `getCustomMethodOptions`, and `getCustomServiceOptions` by matching keys against the exclude list (supporting both literal matches and wildcard patterns). Tested in `266_ts_exclude_options`. +- **`ts.exclude_options` wildcard uses substring match, not prefix match** — The TS plugin's `readOptions()` converts wildcard patterns (e.g., `test.*`) to regex (`test\..*`) and uses `key.match(re)` which performs **substring matching**. So pattern `test.*` excludes key `other.test.foo` because the regex finds `test.foo` as a substring. The Go plugin's `filterExcludedOptions` uses `strings.HasPrefix(opt.key, prefix)` which only matches at the **start** of the key. So `other.test.foo` with pattern `test.*` is excluded by TS but NOT by Go. Root cause: `filterExcludedOptions` uses prefix matching but the TS plugin uses unanchored regex matching. Fix: either use `strings.Contains` instead of `strings.HasPrefix`, or compile the pattern as a regex and use `regexp.MatchString` for full compatibility.

The TS `write()` method forces `emitDefaultValues: true` for enum oneof members too. Also applies to NullValue enum in a oneof. - **Same oneof-default bug applies to nested option messages**: If a custom option message has a nested message field whose type contains a proto3 oneof with default scalar values, the recursive `parseMessageValue` would also filter them incorrectly. - **Message-typed oneof member set to empty message**: The TS `write()` does NOT force `emitDefaultValues: true` for message-typed oneof members (only scalar/enum).

For literals, it uses `key === pattern` (exact equality). For wildcards, it uses `key.match(re)` (regex substring match). The Go plugin's `filterExcludedOptions` converts ALL patterns to regex and uses `re.MatchString()` (substring match) regardless of whether the pattern has `*`. So a literal pattern `"test.tag"` becomes regex `test\.tag` which matches `"prefix.test.tag"` as a substring. The TS plugin would NOT exclude `"prefix.test.tag"` because `"test.tag" === "prefix.test.tag"` is false. Root cause: `filterExcludedOptions` doesn't distinguish literals from wildcards — it applies regex substring matching to all patterns. Fix: for patterns without `*`, use exact string equality (`opt.key == pattern`) instead of regex. Tested in `268_exclude_options_literal_exact`. +- **`ts.server` service option NOT excluded by TS plugin** — The TS plugin's `getServiceType()` only hardcode-excludes `"ts.client"` from service options (`.concat("ts.client")`). It does NOT exclude `"ts.server"` (field 777702). So when a service has `option (ts.server) = GRPC1_SERVER`, the TS plugin includes `"ts.server": ["GRPC1_SERVER"]` in the generated `ServiceType` options. The Go plugin's `getCustomServiceOptions` at line 1242 excludes BOTH `ts.client` AND `ts.server`. Root cause: RALPH's fix for test 265 over-corrected by also excluding `ts.server`, but the TS plugin only excludes `ts.client`. Fix: remove `|| opt.key == "ts.server"` from line 1242. Additionally, when `ts.server` is set, the TS plugin generates a `test.grpc-server.ts` file that the Go plugin doesn't generate. Tested in `269_ts_server_service_option`. + ### Areas thoroughly tested with NO difference found - All 15 scalar types, maps, enums, oneofs, groups, nested messages, services (all streaming types) - Custom options: scalar, enum, bool, bytes (base64), repeated, nested message, NaN/Infinity floats, negative int32 @@ -102,7 +104,6 @@ You are running inside an automated loop. **Each invocation is stateless** — y - Service/method options (non-WKT types) ### Ideas for future runs -- **`ts.server` service option also excluded**: Same as `ts.client`, the TS plugin may also exclude `ts.server` (field 777702). If RALPH fixes only `ts.client`, test `ts.server` next. - **`ts.exclude_options` file option behavior**: Already tested in 266 (literal) and 267 (wildcard substring). If RALPH fixes prefix→substring, test other edge cases: wildcard `*` at start of pattern (e.g., `*.foo`), multiple `*` in pattern (e.g., `*test*`), pattern that's just `*` (exclude all). - **Same oneof-default bug applies to enum oneof members**: A proto3 oneof with an enum field set to value 0 (default) would also be filtered. The TS `write()` method forces `emitDefaultValues: true` for enum oneof members too.

invocation is stateless** — y - **`ts.server` service option NOT excluded by TS plugin** — The TS plugin's `getServiceType()` only hardcode-excludes `"ts.client"` from service options (`.concat("ts.client")`). It does NOT exclude `"ts.server"` (field 777702). So when a service has `option (ts.server) = GRPC1_SERVER`, the TS plugin includes `"ts.server": ["GRPC1_SERVER"]` in the generated `ServiceType` options. The Go plugin's `getCustomServiceOptions` at line 1242 excludes BOTH `ts.client` AND `ts.server`. Root cause: RALPH's fix for test 265 over-corrected by also excluding `ts.server`, but the TS plugin only excludes `ts.client`. Fix: remove `|| opt.key == "ts.server"` from line 1242. Additionally, when `ts.server` is set, the TS plugin generates a `test.grpc-server.ts` file that the Go plugin doesn't generate. Tested in `269_ts_server_service_option`. +- **GENERIC_SERVER generates .server.ts file** — When a service has `option (ts.server) = GENERIC_SERVER` (enum value 1), the TS plugin generates a `.server.ts` file containing a generic server interface (`export interface IMySvc`). The Go plugin has NO support for `GENERIC_SERVER` at all — it only handles `GRPC1_SERVER` (value 2) via `serviceNeedsGrpc1Server()` and `generateGrpcServerFile()`. There is no `generateGenericServerFile()` function in the Go plugin. Root cause: The Go plugin was only ported for GRPC1_SERVER support. The entire generic server code path (`service-server-generator-generic.js` in the TS plugin) was never implemented. Fix: implement a `generateGenericServerFile()` function that generates the `.server.ts` file with a generic interface mirroring the TS plugin's `ServiceServerGeneratorGeneric.generateInterface()` method. The interface takes a type parameter `T = ServerCallContext` and has a method for each RPC (unary returns `Promise`, server-streaming returns `ServerStreamingCall`, etc.). Tested in `270_generic_server_option`. + ### Areas thoroughly tested with NO difference found - All 15 scalar types, maps, enums, oneofs, groups, nested messages, services (all streaming types) - Custom options: scalar, enum, bool, bytes (base64), repeated, nested message, NaN/Infinity floats, negative int32 @@ -104,6 +106,8 @@ You are running inside an automated loop. **Each invocation is stateless** — y - Service/method options (non-WKT types) ### Ideas for future runs +- **GENERIC_SERVER with streaming methods**: The generic server interface for server-streaming, client-streaming, and bidi-streaming RPCs uses different return types. After RALPH implements the basic generic server file generation, test with all four streaming patterns. +- **GENERIC_SERVER + GRPC1_SERVER on same service**: A service can have `option (ts.server) = GENERIC_SERVER; option (ts.server) = GRPC1_SERVER;` (repeated field). The TS plugin generates BOTH `.server.ts` and `.grpc-server.ts`. Test after RALPH adds GENERIC_SERVER support. - **`ts.exclude_options` file option behavior**: Already tested in 266 (literal) and 267 (wildcard substring). If RALPH fixes prefix→substring, test other edge cases: wildcard `*` at start of pattern (e.g., `*.foo`), multiple `*` in pattern (e.g., `*test*`), pattern that's just `*` (exclude all). - **Same oneof-default bug applies to enum oneof members**: A proto3 oneof with an enum field set to value 0 (default) would also be filtered. The TS `write()` method forces `emitDefaultValues: true` for enum oneof members too. Also applies to NullValue enum in a oneof. - **Same oneof-default bug applies to nested option messages**: If a custom option message has a nested message field whose type contains a proto3 oneof with default scalar values, the recursive `parseMessageValue` would also filter them incorrectly. diff --git a/protoc-gen-kaja/status.txt b/protoc-gen-kaja/status.txt index c8e8a135..7d68d91d 100644 --- a/protoc-gen-kaja/status.txt +++ b/protoc-gen-kaja/status.txt @@ -1 +1 @@ -DONE +HAHA diff --git a/protoc-gen-kaja/tests/270_generic_server_option/protobuf-ts.proto b/protoc-gen-kaja/tests/270_generic_server_option/protobuf-ts.proto new file mode 100644 index 00000000..ff92b601 --- /dev/null +++ b/protoc-gen-kaja/tests/270_generic_server_option/protobuf-ts.proto @@ -0,0 +1,83 @@ +// This proto file is part of protobuf-ts.

invocation is stateless** — y - **GENERIC_SERVER generates .server.ts file** — When a service has `option (ts.server) = GENERIC_SERVER` (enum value 1), the TS plugin generates a `.server.ts` file containing a generic server interface (`export interface IMySvc`). The Go plugin has NO support for `GENERIC_SERVER` at all — it only handles `GRPC1_SERVER` (value 2) via `serviceNeedsGrpc1Server()` and `generateGrpcServerFile()`. There is no `generateGenericServerFile()` function in the Go plugin. Root cause: The Go plugin was only ported for GRPC1_SERVER support. The entire generic server code path (`service-server-generator-generic.js` in the TS plugin) was never implemented. Fix: implement a `generateGenericServerFile()` function that generates the `.server.ts` file with a generic interface mirroring the TS plugin's `ServiceServerGeneratorGeneric.generateInterface()` method. The interface takes a type parameter `T = ServerCallContext` and has a method for each RPC (unary returns `Promise`, server-streaming returns `ServerStreamingCall`, etc.). Tested in `270_generic_server_option`. +- **GENERIC_SERVER streaming import ordering** — When a GENERIC_SERVER service has streaming RPCs, the `.server.ts` file needs `RpcInputStream` and `RpcOutputStream` imports from `@protobuf-ts/runtime-rpc`. The TS plugin's import system prepends each import at the TOP of the file as it's encountered during code generation. Order of encounter: (1) `ServerCallContext` at start of `generateInterface`, (2) message type imports (`Req`, `Resp`) from first method's `createUnary`, (3) `RpcInputStream` from `createServerStreaming`, (4) `RpcOutputStream` from `createClientStreaming`. Since each is prepended, the final file order is reversed: `RpcOutputStream, RpcInputStream, Resp, Req, ServerCallContext`. The Go plugin collects message type imports first (in reverse method order), then emits runtime-rpc streaming imports, then `ServerCallContext` — producing: `Resp, Req, RpcOutputStream, RpcInputStream, ServerCallContext`. Root cause: `generateGenericServerFile` emits imports in a fixed order (message types → streaming types → ServerCallContext) instead of matching the TS plugin's prepend-as-encountered order. Fix: emit runtime-rpc streaming imports BEFORE message type imports: `RpcOutputStream, RpcInputStream, Resp, Req, ServerCallContext`. Tested in `271_generic_server_streaming`. + ### Areas thoroughly tested with NO difference found - All 15 scalar types, maps, enums, oneofs, groups, nested messages, services (all streaming types) - Custom options: scalar, enum, bool, bytes (base64), repeated, nested message, NaN/Infinity floats, negative int32 diff --git a/protoc-gen-kaja/status.txt b/protoc-gen-kaja/status.txt index c8e8a135..7d68d91d 100644 --- a/protoc-gen-kaja/status.txt +++ b/protoc-gen-kaja/status.txt @@ -1 +1 @@ -DONE +HAHA diff --git a/protoc-gen-kaja/tests/271_generic_server_streaming/protobuf-ts.proto b/protoc-gen-kaja/tests/271_generic_server_streaming/protobuf-ts.proto new file mode 100644 index 00000000..ff92b601 --- /dev/null +++ b/protoc-gen-kaja/tests/271_generic_server_streaming/protobuf-ts.proto @@ -0,0 +1,83 @@ +// This proto file is part of protobuf-ts.

Since imports are prepended, the final order is `RpcInputStream` above `RpcOutputStream`. The Go plugin's import loop (lines 9107-9114) checks `ss` before `cs`, so it prepends `RpcInputStream` first, then `RpcOutputStream` on top — resulting in `RpcOutputStream` above `RpcInputStream` (reversed). Root cause: the `ss`/`cs` check order in `generateGenericServerFile` doesn't match the TS plugin's encounter order in `createBidi()`. Fix: swap the `ss` and `cs` blocks (check `cs` first for `RpcOutputStream`, then `ss` for `RpcInputStream`). Tested in `273_generic_server_bidi`. +- **`ts.client = NO_CLIENT` not suppressing client file generation** — When a service has `option (ts.client) = NO_CLIENT;` (enum value 0), the TS plugin reads the `ClientStyle` repeated option and sees `[NO_CLIENT]`, so it does NOT generate a `.client.ts` file. The Go plugin has no logic to read the `ts.client` service option value — it unconditionally generates a `.client.ts` for every proto file with services (line 389: `generateClientFile` called without checking client style). Root cause: Go plugin never reads field 777701 from `ServiceOptions` to determine which client styles to generate. It only knows about `ts.client` for the purpose of EXCLUDING it from the service options output (line 1426). Fix: add a `getServiceClientStyles()` function (similar to `getServiceServerStyles()`) that reads field 777701 from `ServiceOptions`, then check if `NO_CLIENT` is the only style (or if the list is non-empty and doesn't contain `GENERIC_CLIENT`) before generating the client file.

The Go plugin has no knowledge of `GRPC1_CLIENT` and would generate a `.client.ts` instead. This is two bugs: (1) wrong file generated, (2) wrong file NOT generated. +- **Multiple `ts.client` values on same service** — `option (ts.client) = NO_CLIENT; option (ts.client) = GENERIC_CLIENT;` — the TS plugin processes all values. If NO_CLIENT and GENERIC_CLIENT are both present, the GENERIC_CLIENT still generates. Test if Go handles this. +- **Default client style when no `ts.client` is set** — When no `ts.client` option is specified, the TS plugin defaults to `GENERIC_CLIENT`. The Go plugin also generates a client. Both should match. But check if the TS plugin defaults differently for services in files that import `protobuf-ts.proto` vs those that don't. - **GENERIC_SERVER with streaming methods**: The generic server interface for server-streaming, client-streaming, and bidi-streaming RPCs uses different return types.

invocation is stateless** — y - **GENERIC_SERVER streaming import ordering** — When a GENERIC_SERVER service has streaming RPCs, the `.server.ts` file needs `RpcInputStream` and `RpcOutputStream` imports from `@protobuf-ts/runtime-rpc`. The TS plugin's import system prepends each import at the TOP of the file as it's encountered during code generation. Order of encounter: (1) `ServerCallContext` at start of `generateInterface`, (2) message type imports (`Req`, `Resp`) from first method's `createUnary`, (3) `RpcInputStream` from `createServerStreaming`, (4) `RpcOutputStream` from `createClientStreaming`. Since each is prepended, the final file order is reversed: `RpcOutputStream, RpcInputStream, Resp, Req, ServerCallContext`. The Go plugin collects message type imports first (in reverse method order), then emits runtime-rpc streaming imports, then `ServerCallContext` — producing: `Resp, Req, RpcOutputStream, RpcInputStream, ServerCallContext`. Root cause: `generateGenericServerFile` emits imports in a fixed order (message types → streaming types → ServerCallContext) instead of matching the TS plugin's prepend-as-encountered order. Fix: emit runtime-rpc streaming imports BEFORE message type imports: `RpcOutputStream, RpcInputStream, Resp, Req, ServerCallContext`. Tested in `271_generic_server_streaming`. +- **GRPC1_CLIENT server-streaming/bidi parameter signatures differ** — For server-streaming and bidi methods in the `.grpc-client.ts` file, the TS plugin generates optional parameters in both interface overloads and implementation: (1) Interface: `metadata?: grpc.Metadata` (optional `?`), Go: `metadata: grpc.Metadata` (required). (2) Implementation: `metadata?: grpc.Metadata | grpc.CallOptions` (optional `?`), Go: `metadata: grpc.Metadata | grpc.CallOptions | undefined` (union with undefined instead of optional). (3) Return statement: TS passes `options` without cast, Go wraps as `(options as any)`. Root cause: The TS plugin's `createServerStreamingSignatures()` uses `ts.createToken(ts.SyntaxKind.QuestionToken)` on the metadata parameter to make it optional. The TS printer renders this as `metadata?:` with the type being just `grpc.Metadata`. The Go plugin generates `metadata: grpc.Metadata` (no `?`, no `| undefined`). Similarly for the implementation signature, TS uses an optional parameter (`?:`) with a union type, while Go uses a required parameter with `| undefined` added to the union. And the TS `createServerStreaming()` and `createDuplexStreaming()` methods pass `options` directly (no `as any` cast) while the Go plugin adds `(options as any)`. Fix: In `generateGrpcClientFile`, for server-streaming interface overload, add `?` to metadata parameter. For implementation signatures, use `?:` instead of adding `| undefined`. For server-streaming/bidi return statements, pass `options` directly instead of `(options as any)`. Tested in `276_grpc1_client_streaming`. + ### Areas thoroughly tested with NO difference found - All 15 scalar types, maps, enums, oneofs, groups, nested messages, services (all streaming types) - Custom options: scalar, enum, bool, bytes (base64), repeated, nested message, NaN/Infinity floats, negative int32 diff --git a/protoc-gen-kaja/tests/276_grpc1_client_streaming/protobuf-ts.proto b/protoc-gen-kaja/tests/276_grpc1_client_streaming/protobuf-ts.proto new file mode 100644 index 00000000..ff92b601 --- /dev/null +++ b/protoc-gen-kaja/tests/276_grpc1_client_streaming/protobuf-ts.proto @@ -0,0 +1,83 @@ +// This proto file is part of protobuf-ts.

(2) Implementation: `metadata?: grpc.Metadata | grpc.CallOptions` (optional `?`), Go: `metadata: grpc.Metadata | grpc.CallOptions | undefined` (union with undefined instead of optional). (3) Return statement: TS passes `options` without cast, Go wraps as `(options as any)`. Root cause: The TS plugin's `createServerStreamingSignatures()` uses `ts.createToken(ts.SyntaxKind.QuestionToken)` on the metadata parameter to make it optional. The TS printer renders this as `metadata?:` with the type being just `grpc.Metadata`. The Go plugin generates `metadata: grpc.Metadata` (no `?`, no `| undefined`). Similarly for the implementation signature, TS uses an optional parameter (`?:`) with a union type, while Go uses a required parameter with `| undefined` added to the union. And the TS `createServerStreaming()` and `createDuplexStreaming()` methods pass `options` directly (no `as any` cast) while the Go plugin adds `(options as any)`. Fix: In `generateGrpcClientFile`, for server-streaming interface overload, add `?` to metadata parameter. For implementation signatures, use `?:` instead of adding `| undefined`. For server-streaming/bidi return statements, pass `options` directly instead of `(options as any)`.

Root cause: the bidi streaming block in `generateGrpcClientFile` (around line 9450) was not updated when RALPH fixed the server-streaming block. Fix: apply the same changes to the `cs && ss` (bidi) code path: use `metadata?:` with the base union type, and pass `options` without `(... as any)`.

The Go plugin's `fileNeedsClient` treats any non-NO_CLIENT (non-0) style as needing a generic `.client.ts`, so it generates the wrong file type entirely: (1) Go generates `.client.ts` (generic client) which TS doesn't, (2) TS generates `.grpc-client.ts` which Go doesn't. The `.grpc-client.ts` has a completely different structure — `extends grpc.Client`, uses `grpc.Metadata`, `grpc.CallOptions`, `grpc.ClientUnaryCall`, multiple overload signatures per method, `makeUnaryRequest`/`makeServerStreamRequest` calls, `BinaryReadOptions`/`BinaryWriteOptions`. Root cause: `fileNeedsClient` doesn't distinguish GENERIC_CLIENT from GRPC1_CLIENT, and there's no `generateGrpcClientFile()` function. Tested in `275_grpc1_client_option`. +- **GRPC1_SERVER definition variable name with underscored service** — When a service name contains underscores (e.g., `service my_svc`), the TS plugin computes the definition variable name by lowercasing the first character of the raw service name: `"my_svc"` → `"my_svcDefinition"`. The Go plugin applies full `toCamelCase` transformation: `"my_svc"` → `"mySvc"` → `"mySvcDefinition"`. Root cause: `generateGrpcServerFile` uses `g.toCamelCase(baseName) + "Definition"` but the TS plugin's `registerSymbols` does `${basename[0].toLowerCase()}${basename.substring(1)}Definition` which only lowercases the first character. Fix: replace `g.toCamelCase(baseName)` with a simple first-char-lowercase operation on the raw service name. Tested in `278_grpc_server_definition_name`. + ### Ideas for future runs - **Multiple `ts.client` values on same service** — `option (ts.client) = NO_CLIENT; option (ts.client) = GENERIC_CLIENT;` — the TS plugin processes all values. If NO_CLIENT and GENERIC_CLIENT are both present, the GENERIC_CLIENT still generates. Test if Go handles this. - **Default client style when no `ts.client` is set** — When no `ts.client` option is specified, the TS plugin defaults to `GENERIC_CLIENT`. The Go plugin also generates a client. Both should match. But check if the TS plugin defaults differently for services in files that import `protobuf-ts.proto` vs those that don't. diff --git a/protoc-gen-kaja/tests/278_grpc_server_definition_name/protobuf-ts.proto b/protoc-gen-kaja/tests/278_grpc_server_definition_name/protobuf-ts.proto new file mode 100644 index 00000000..ff92b601 --- /dev/null +++ b/protoc-gen-kaja/tests/278_grpc_server_definition_name/protobuf-ts.proto @@ -0,0 +1,83 @@ +// This proto file is part of protobuf-ts.

For unary methods this happens to match (TS encounters `Req` input first, then `Resp` callback → prepend gives `Resp, Req`). But client streaming reverses the encounter order.

Since imports are prepended, `Req` ends up above `Resp`. The Go plugin's import collection loop always processes `resType` before `reqType` regardless of streaming type, producing `Resp` above `Req`. For unary methods this happens to match (TS encounters `Req` input first, then `Resp` callback → prepend gives `Resp, Req`). But client streaming reverses the encounter order. Root cause: `generateGrpcClientFile`'s import loop uses a fixed `resType, reqType` order for all method types. For client-streaming methods, the order should be `reqType, resType` to match the TS prepend pattern. Fix: check `cs && !ss` and swap the append order for client streaming.

Root cause: the reverse-iterate-and-append strategy correctly simulates prepend for types introduced within a single method, but breaks when the same types are introduced across different methods because the first-seen method differs between forward (TS) and reverse (Go) iteration. Fix: the Go plugin needs to track which types have already been seen and match the TS encounter order, possibly by simulating forward iteration with prepend.

The generic-server file at line 9702 still checks `service.GetOptions().GetDeprecated()` in method-level JSDoc, incorrectly adding `@deprecated` to non-deprecated methods in deprecated services. The grpc-server file (line 8983) does NOT have the service check (already correct), but still has `g.isFileDeprecated()`. Tested generic-server in `281_generic_server_deprecated_service`. Next: test grpc-server with file-level deprecation separately. -- **File-level deprecation propagation** — Same class of bug: if a FILE is deprecated (`option deprecated = true;` in FileOptions), the Go plugin propagates `@deprecated` to all methods. The TS plugin only adds `@deprecated` to the file header comment, not to individual methods. Test with `option deprecated = true;` at file level (not service level). +- **File-level deprecation propagation** — TESTED: NOT A BUG. When a file has `option deprecated = true;`, the TS plugin ALSO adds `@deprecated` to method-level JSDoc in grpc-server files. Both plugins agree.

Test if Go handles this. - **Default client style when no `ts.client` is set** — When no `ts.client` option is specified, the TS plugin defaults to `GENERIC_CLIENT`. The Go plugin also generates a client. Both should match.
