Nielsen <lrn@google.com> Date: Mon Sep 2 16:58:43 2024 +0200 Use `Map.of` instead of `Map.from` in grpc client. (grpc#724) * Use `Map.of` instead of `Map.from` in grpc client. `Map.of` creates a new map with the same keys, values and *type* as the original map, when used without type arguments or context type, where `Map.from` creates a `Map<dynamic, dynamic>`. (This code failed on an attempt to make `Map.unmodifiable` be more strictly typed, like `Map.of` instead of `Map.from`, showing that an intermediate map had type `Map<dynamic, dynamic>` unnecessarily). Same for using `List.of` instead of `List.from`. The new code should be (microscopically) more efficient and type safe, and is forwards-compatible with a stronger type on `Map.unmodifiable`. (The code can be optimized more. For example `List.of(list1)..addAll(list2)` can be just `list1 + list2` or `[...list1, ...list2]`, both of which may know the total number of elements when doing the initial list allocation. This is a minimal change to allow the type changes for `.unmodifiable` to get past this very initial blocker in internal tests.) * Add changelog and minor version increment. And my save removes trailing spaces. commit 4f6fe9b Author: c-lucera-pvotal <91328643+c-lucera-pvotal@users.noreply.github.com> Date: Wed Aug 28 08:18:15 2024 +0200 fix: fix headers not completing when call is terminated (grpc#728) Fixes grpc#727 commit c18e185 Author: Kevin Moore <kevmoo@users.noreply.github.com> Date: Wed Jul 24 14:24:57 2024 -0700 Fix status badge (grpc#726) commit b999b64 Author: Galen Warren <galen@cvillewarrens.com> Date: Wed Jul 17 08:11:29 2024 -0400 feat: fix hang that occurs when hot restarting (grpc#718) commit bf8bbde Author: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> Date: Mon Jul 1 11:56:47 2024 +0000 Bump dart-lang/setup-dart from 1.6.4 to 1.6.5 (grpc#720) commit 4aa4c8c Author: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> Date: Mon Jul 1 11:52:08 2024 +0000 Bump actions/checkout from 4.1.6 to 4.1.7 (grpc#719) commit dee1b2b Author: Kevin Moore <kevmoo@users.noreply.github.com> Date: Wed May 29 17:23:53 2024 -0700 Update pubspec.yaml commit 52023d4 Author: Kevin Moore <kevmoo@google.com> Date: Tue May 28 14:47:30 2024 -0700 code fixes commit ebb7368 Author: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> Date: Wed May 22 06:56:00 2024 +0000 Bump lints from 3.0.0 to 4.0.0 Bumps [lints](https://github.com/dart-lang/lints) from 3.0.0 to 4.0.0. - [Release notes](https://github.com/dart-lang/lints/releases) - [Changelog](https://github.com/dart-lang/lints/blob/main/CHANGELOG.md) - [Commits](dart-archive/lints@v3.0.0...v4.0.0) --- updated-dependencies: - dependency-name: lints dependency-type: direct:production update-type: version-update:semver-major ...

Safer sendTrailers() Implementation • Location: lib/src/server/handler.dart:404-410 • View: https://github.com/open-runtime/grpc-dart/blob/aot_monorepo_compat/lib/src/server/handler.dart#L404-L410 ```dart // Safely send headers - the stream might already be closed try { _stream.sendHeaders(outgoingTrailers, endStream: true); } catch (e) { // Stream is already closed - this can happen during concurrent termination // The client is gone, so we can't send the trailers anyway } ``` 3. Improved _onDoneExpected() Error Handling • Location: lib/src/server/handler.dart:442-450 • View: https://github.com/open-runtime/grpc-dart/blob/aot_monorepo_compat/lib/src/server/handler.dart#L442-L450 ```dart // Safely add error to requests stream if (_requests != null && !_requests!.isClosed) { try { _requests!.addError(error); } catch (e) { // Stream was closed - ignore this error } } ``` Impact: • Prevents server crashes during concurrent stream termination • Graceful handling of edge cases in error paths • Production-ready error handling with defensive programming • Maintains service availability under load DOCUMENTATION ADDED =================== 1.
