Changes: - Remove AcquireLock/ReleaseLock/RenewLock RPCs from proto - Add atomic index operations: AddSessionToIndex, UpdateSessionInIndex, RemoveSessionFromIndex (server acquires/releases locks internally) - Remove WithLockedIndex methods and _holderId/_indexLock from SessionManager - Rename DTO types with Dto suffix to avoid proto-generated type conflicts (SessionInfoDto, WalEntryDto, CheckpointInfoDto, SessionIndexEntryDto) - Fix GrpcLauncher to find Rust binary via correct relative paths - Update .gitignore for Rust artifacts and Claude Code files This fixes the ParallelCreation_NoLostSessions race condition where parallel session creation could lose sessions due to client-side lock/load/save/unlock races. Server-side atomic operations ensure index updates are serialized correctly. All 428 tests pass.

Add build-storage job that builds docx-mcp-storage for 6 targets: linux-x64, linux-arm64, macos-x64, macos-arm64, windows-x64, windows-arm64 - Tests now download linux-x64 storage server before running - Windows installer downloads platform-specific storage server - macOS installer downloads both arch binaries and creates universal binary - Implement fork/join semantics: parent kills child via ProcessExit event - Add unique PID-based socket paths to prevent conflicts - Add parent death monitoring (prctl on Linux, polling fallback on macOS/Windows) Co-Authored-By: Claude Opus 4.5 --- .github/workflows/docker-build.yml | 115 ++++- Cargo.lock | 69 ++- Cargo.toml | 5 +- Dockerfile | 2 +- crates/docx-mcp-storage/Cargo.toml | 11 + crates/docx-mcp-storage/src/config.rs | 5 + crates/docx-mcp-storage/src/lock/file.rs | 508 +++++++------------ crates/docx-mcp-storage/src/lock/traits.rs | 50 +- crates/docx-mcp-storage/src/main.rs | 148 +++++- crates/docx-mcp-storage/src/service.rs | 7 -

KV was rate-limited (~1000 writes/min) and eventually-consistent, making it unsuitable as a distributed lock. R2 conditional PUT (If-Match/If-None-Match) provides true CAS semantics without the rate limit bottleneck. - Add ETag primitives: get_object_with_etag, put_object_conditional - Add cas_index() for atomic read-modify-write on session index - Add cas_append_wal/cas_truncate_wal for WAL race condition fix - Migrate index storage from KV to R2 ({tenant}/index.json) - Add exponential backoff with jitter retry for 429/5xx on all R2 ops - Remove KvClient, KvLock, reqwest/urlencoding dependencies - Use concrete Arc instead of dyn traits for CAS access Tested: 422/428 .NET tests pass against live R2 (6 expected failures for LocalFile source type correctly rejected by R2 backend).

From a96e50f214b23173759f4d0314795cd90968e2c4 Mon Sep 17 00:00:00 2001 From: Laurent Valdes Date: Fri, 13 Feb 2026 20:17:41 +0100 Subject: [PATCH 35/85] refactor: split IStorageClient into IHistoryStorage + ISyncStorage with caller-orchestrated sync MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Split the monolithic IStorageClient/StorageClient into two focused interfaces and clients for the dual-server architecture: - IHistoryStorage (sessions, WAL, index, checkpoints) → remote Cloudflare R2 - ISyncStorage (file sync, filesystem watch) → local embedded staticlib SessionManager now depends only on IHistoryStorage (removed all sync/watch/ tracker logic). New SyncManager depends only on ISyncStorage. Auto-save orchestration moved to callers (Tool classes, CLI, HostedServices). Updated all 13 mutation call sites, DI wiring (MCP + CLI), tests (428 pass), and Rust register_source for dual-server compatibility (31 pass).

charset=UTF-8 Content-Transfer-Encoding: 8bit TestHelpers now creates separate channels in dual-server mode: IHistoryStorage → remote STORAGE_GRPC_URL, ISyncStorage → local embedded. All previously-skipped tests (AutoSave, ExternalSync, ExternalChangeTracker, CommentRestart) now run in both embedded and Cloudflare R2 modes. Updated CLAUDE.md with dual-server architecture docs and Cloudflare test instructions. 428 tests pass in both modes (embedded + STORAGE_GRPC_URL=cloudflare).

Sync and watch are handled by dedicated backends (gdrive, local). Remove unused service_sync, service_watch, sync/ and watch/ modules. Fix Dockerfile CMD that passed unsupported --transport flag.

Proxy now forwards all HTTP requests transparently to the backend, injecting X-Tenant-Id from PAT auth. Simplifies error handling and config.

Add BrowsableBackend trait and implementations for listing connections, browsing files (.docx + folders), and downloading from sources. New MCP tools: list_connections, list_connection_files. Tool descriptions now instruct the LLM to call list_connections first to discover available sources, preventing hallucinated "local" option in cloud deployments. Fix Google OAuth scope: drive.file → drive.readonly + drive.file to allow browsing all Drive files (not just app-created ones).

This ensures external change state survives restarts and is shared across distributed MCP instances. Changes: - Proto: add pending_external_change to SessionIndexEntry, UpdateSessionInIndexRequest, SessionExistsResponse - Rust: handle field in local + cloudflare storage backends - C#: extend IHistoryStorage/HistoryStorageClient with new field - Rewrite ExternalChangeGate to use IHistoryStorage (no more in-memory state) - Remove ExternalChangeTracker, ExternalChangeNotificationService, WatchDaemon - Simplify tool DI: replace ExternalChangeTracker with ExternalChangeGate - Update all 13 test files for new gate API Co-Authored-By: Claude Opus 4.6 --- crates/docx-storage-cloudflare/src/service.rs | 19 +- crates/docx-storage-core/src/storage.rs | 3 + crates/docx-storage-local/src/service.rs | 18 +- .../docx-storage-local/src/storage/local.rs | 3 + .../docx-storage-local/src/sync/local_file.rs | 2 + proto/storage.proto | 3 + src/DocxMcp.Cli/Program.cs | 188 +----- src/DocxMcp.Cli/WatchDaemon.cs | 313 ---------- src/DocxMcp.Grpc/HistoryStorageClient.cs | 6 +- src/DocxMcp.Grpc/IHistoryStorage.cs | 3 +- .../ExternalChanges/ExternalChangeGate.cs | 159 +++++ .../ExternalChangeNotificationService.cs | 88 --- .../ExternalChanges/ExternalChangePatch.cs | 155 ----- .../ExternalChanges/ExternalChangeTracker.cs | 553 ------------------ src/DocxMcp/Program.cs | 13 +- src/DocxMcp/SessionRestoreService.cs | 9 +- src/DocxMcp/Tools/CommentTools.cs | 13 +- src/DocxMcp/Tools/DocumentTools.cs | 14 - src/DocxMcp/Tools/ElementTools.cs | 30 +- src/DocxMcp/Tools/ExternalChangeTools.cs | 244 +++++--- src/DocxMcp/Tools/HistoryTools.cs | 16 +- src/DocxMcp/Tools/PatchTool.cs | 28 +- src/DocxMcp/Tools/RevisionTools.cs | 13 +- src/DocxMcp/Tools/StyleTools.cs | 13 +- tests/DocxMcp.Tests/AutoSaveTests.cs | 6 +- tests/DocxMcp.Tests/CommentTests.cs | 129 ++-- .../ExternalChangeTrackerTests.cs | 233 +++----- tests/DocxMcp.Tests/ExternalSyncTests.cs | 50 +- tests/DocxMcp.Tests/PatchLimitTests.cs | 10 +- tests/DocxMcp.Tests/PatchResultTests.cs | 50 +- tests/DocxMcp.Tests/QueryRoundTripTests.cs | 6 +- .../DocxMcp.Tests/SessionPersistenceTests.cs | 7 +- tests/DocxMcp.Tests/StyleTests.cs | 135 ++--- tests/DocxMcp.Tests/SyncDuplicateTests.cs | 46 +- tests/DocxMcp.Tests/TableModificationTests.cs | 28 +- tests/DocxMcp.Tests/TestHelpers.cs | 10 + tests/DocxMcp.Tests/UndoRedoTests.cs | 103 ++-- 37 files changed, 809 insertions(+), 1910 deletions(-) delete mode 100644 src/DocxMcp.Cli/WatchDaemon.cs create mode 100644 src/DocxMcp/ExternalChanges/ExternalChangeGate.cs delete mode 100644 src/DocxMcp/ExternalChanges/ExternalChangeNotificationService.cs delete mode 100644 src/DocxMcp/ExternalChanges/ExternalChangeTracker.cs diff --git a/crates/docx-storage-cloudflare/src/service.rs b/crates/docx-storage-cloudflare/src/service.rs index 2ac7069..0aeb03a 100644 --- a/crates/docx-storage-cloudflare/src/service.rs +++ b/crates/docx-storage-cloudflare/src/service.rs @@ -221,7 +221,19 @@ impl StorageService for StorageServiceImpl { .await .map_storage_err()?;

From d93d48e73fcc19f3903168b646f981050a4bd997 Mon Sep 17 00:00:00 2001 From: Laurent Valdes Date: Mon, 16 Feb 2026 05:21:20 +0100 Subject: [PATCH 59/85] feat: proxy transparent session recovery on backend restart When the .NET MCP backend restarts, in-memory transport sessions are lost and clients get 404 in a loop. The proxy now detects 404 responses, re-initializes the MCP session transparently, and retries the original request. Per-tenant recovery is serialized via an async mutex to avoid duplicate initialize calls under concurrent load.

Common causes: +- **HTTP/2 (h2c) mismatch**: Koyeb's edge may connect to containers via HTTP/2 cleartext (h2c). If the server only speaks HTTP/1.1 (e.g. `axum::serve`), Koyeb returns 502 even though health checks pass (health checks use HTTP/1.1). Fix: use `hyper-util::server::conn::auto::Builder` for dual-stack HTTP/1.1 + h2c. +- **Health check testing upstream**: If `/health` checks upstream services (e.g. mcp-http), it can timeout during cold start, making Koyeb mark the container as unhealthy. Fix: `/health` should only test that the proxy itself is running. Use `/upstream-health` for deep checks. +- **Upstream unreachable**: If proxy is healthy but returns 502, check mcp-http logs first (`koyeb instances logs --tail`). -**Testing the proxy:** Always use a real PAT token (e.g. `dxs_539de...`). Never use fake tokens like `dxs_test` — the proxy validates against D1 and will reject them before even forwarding. +**IMPORTANT — PAT tokens:** NEVER use fake/placeholder tokens like `dxs_test` or `dxs_fake`. The proxy validates every token against Cloudflare D1 and rejects invalid ones immediately. Always use a real PAT token from the D1 `pat` table (format: `dxs_<40-char-hex>`). To get one, query D1 directly or create one via the website. **Pulumi provider bug:** `scale_to_zero=True` on mesh-only services (no public route) fails with Pulumi provider validation error `"at least one route is required for services scaling to zero"`. The Koyeb API/CLI accepts it fine.
