Replaced `vscode-ws-jsonrpc` with a custom RPC protocol that is better suited for handling binary data and enables message tunneling. + This impacts all main concepts of the messaging API. The API no longer exposes a `Connection` object and uses a generic `Channel` implementation instead. + - Replaces usage of `vscode-json-rpc`'s `Connection` with the new generic `Channel`. Affects `AbstractConnectionProvider`, `MessagingService`, `IPCConnectionProvider`, `ElectronMessagingService` + - `MessagingService`: No longer offers the `listen` and `forward` method. Use `wsChannel` instead. + - `RemoteFileSystemServer`: Use `UInt8Array` instead of plain number arrays for all arguments and return type that store binary data + - `DebugAdapter`: Replaced the debug-service internal `Channel` implementation with the newly introduced generic `Channel`. + [#11011](https://github.com/eclipse-theia/theia/pull/11011) - Contributed on behalf of STMicroelectronics. + + ## v1.25.0 - 4/28/2022 [1.25.0 Milestone](https://github.com/eclipse-theia/theia/milestone/35) diff --git a/package.json b/package.json index 950701b6136a3..6b294c3fed0c2 100644 --- a/package.json +++ b/package.json @@ -10,6 +10,8 @@ "**/@types/node": "12" }, "devDependencies": { + "@types/chai": "4.3.0", + "@types/chai-spies": "1.0.3", "@types/chai-string": "^1.4.0", "@types/jsdom": "^11.0.4", "@types/node": "12", @@ -20,6 +22,8 @@ "@typescript-eslint/eslint-plugin": "^4.8.1", "@typescript-eslint/eslint-plugin-tslint": "^4.8.1", "@typescript-eslint/parser": "^4.8.1", + "chai": "4.3.4", + "chai-spies": "1.0.0", "chai-string": "^1.4.0", "chalk": "4.0.0", "concurrently": "^3.5.0", diff --git a/packages/core/README.md b/packages/core/README.md index 64537785cf2f5..9ddef5f7b5b30 100644 --- a/packages/core/README.md +++ b/packages/core/README.md @@ -96,7 +96,6 @@ export class SomeClass { - `react-virtualized` (from [`react-virtualized@^9.20.0`](https://www.npmjs.com/package/react-virtualized)) - `vscode-languageserver-protocol` (from [`vscode-languageserver-protocol@~3.15.3`](https://www.npmjs.com/package/vscode-languageserver-protocol)) - `vscode-uri` (from [`vscode-uri@^2.1.1`](https://www.npmjs.com/package/vscode-uri)) - - `vscode-ws-jsonrpc` (from [`vscode-ws-jsonrpc@^0.2.0`](https://www.npmjs.com/package/vscode-ws-jsonrpc)) - `dompurify` (from [`dompurify@^2.2.9`](https://www.npmjs.com/package/dompurify)) - `express` (from [`express@^4.16.3`](https://www.npmjs.com/package/express)) - `lodash.debounce` (from [`lodash.debounce@^4.0.8`](https://www.npmjs.com/package/lodash.debounce)) diff --git a/packages/core/package.json b/packages/core/package.json index 01c2c52c39c8d..df71d5dfcc1ee 100644 --- a/packages/core/package.json +++ b/packages/core/package.json @@ -68,7 +68,6 @@ "uuid": "^8.3.2", "vscode-languageserver-protocol": "~3.15.3", "vscode-uri": "^2.1.1", - "vscode-ws-jsonrpc": "^0.2.0", "ws": "^7.1.2", "yargs": "^15.3.1" }, @@ -108,8 +107,7 @@ "react-dom", "react-virtualized", "vscode-languageserver-protocol", - "vscode-uri", - "vscode-ws-jsonrpc" + "vscode-uri" ], "export =": [ "dompurify as DOMPurify", diff --git a/packages/core/shared/vscode-ws-jsonrpc/index.d.ts b/packages/core/shared/vscode-ws-jsonrpc/index.d.ts deleted file mode 100644 index b11ff897103ed..0000000000000 --- a/packages/core/shared/vscode-ws-jsonrpc/index.d.ts +++ /dev/null @@ -1 +0,0 @@ -export * from 'vscode-ws-jsonrpc';
