From ff439e450f9953068f464f1ea09f0a3d816818b7 Mon Sep 17 00:00:00 2001 From: Elias Bachaalany Date: Fri, 28 Nov 2025 11:32:50 -0800 Subject: [PATCH 1/9] Fix macOS SSE server test connection issues Remove problematic connection test that was causing macOS CI failures: - Removed immediate-cancel connection check (lines 51-67) - Increased server startup wait from 1s to 2s for macOS - Added 100ms delay before SSE thread connection attempts The test connection was canceling immediately (line 61 returned false) which caused connection handling errors on macOS that persisted into the actual test. This left the server in a bad state for subsequent POST and SSE connections.

Issue: Windows CI failed at interactions.cpp:2307 with C1060 during both Debug and Release builds. The file was too large for MSVC to compile in CI's constrained environment, despite compiling fine locally with the same compiler version (MSVC 14.44.35207). Solution: Split into 3 parts following the same pattern as commit 54dc027 which explicitly "split large test files for maintainability": - interactions_part1.cpp (55 tests, 1,989 lines) - Core Tools/Resources/Prompts - interactions_part2.cpp (59 tests, 2,104 lines) - Data types/Validation - interactions_part3.cpp (50 tests, 1,741 lines) - Server capabilities/Notifications All 164 tests accounted for and passing locally (3/3 tests, 0.04s). Related: PR #11 (43e5e64) which introduced the large interactions.cpp file. This change maintains all test coverage while fixing Windows CI builds. --- CMakeLists.txt | 15 +- tests/server/interactions.cpp | 5548 --------------------------- tests/server/interactions_part1.cpp | 1990 ++++++++++ tests/server/interactions_part2.cpp | 2105 ++++++++++ tests/server/interactions_part3.cpp | 1742 +++++++++ 5 files changed, 5849 insertions(+), 5551 deletions(-) delete mode 100644 tests/server/interactions.cpp create mode 100644 tests/server/interactions_part1.cpp create mode 100644 tests/server/interactions_part2.cpp create mode 100644 tests/server/interactions_part3.cpp diff --git a/CMakeLists.txt b/CMakeLists.txt index f583980..42daa39 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -229,9 +229,18 @@ if(FASTMCPP_BUILD_TESTS) target_link_libraries(fastmcpp_server_patterns PRIVATE fastmcpp_core) add_test(NAME fastmcpp_server_patterns COMMAND fastmcpp_server_patterns) - add_executable(fastmcpp_server_interactions tests/server/interactions.cpp) - target_link_libraries(fastmcpp_server_interactions PRIVATE fastmcpp_core) - add_test(NAME fastmcpp_server_interactions COMMAND fastmcpp_server_interactions) + # Split into 3 parts to avoid MSVC heap exhaustion on CI (C1060) + add_executable(fastmcpp_server_interactions_part1 tests/server/interactions_part1.cpp) + target_link_libraries(fastmcpp_server_interactions_part1 PRIVATE fastmcpp_core) + add_test(NAME fastmcpp_server_interactions_part1 COMMAND fastmcpp_server_interactions_part1) + + add_executable(fastmcpp_server_interactions_part2 tests/server/interactions_part2.cpp) + target_link_libraries(fastmcpp_server_interactions_part2 PRIVATE fastmcpp_core) + add_test(NAME fastmcpp_server_interactions_part2 COMMAND fastmcpp_server_interactions_part2) + + add_executable(fastmcpp_server_interactions_part3 tests/server/interactions_part3.cpp) + target_link_libraries(fastmcpp_server_interactions_part3 PRIVATE fastmcpp_core) + add_test(NAME fastmcpp_server_interactions_part3 COMMAND fastmcpp_server_interactions_part3) add_executable(fastmcpp_server_context_meta tests/server/context_meta.cpp) target_link_libraries(fastmcpp_server_context_meta PRIVATE fastmcpp_core) diff --git a/tests/server/interactions.cpp b/tests/server/interactions.cpp deleted file mode 100644 index f0fd3a2..0000000 --- a/tests/server/interactions.cpp +++ /dev/null @@ -1,5548 +0,0 @@ -/// @file tests/server/interactions.cpp -/// @brief Server interaction tests - client<->server roundtrip tests -/// Mirrors Python's test_server_interactions.py where applicable - -#include "fastmcpp/client/client.hpp" -#include "fastmcpp/client/transports.hpp" -#include "fastmcpp/server/server.hpp" -#include "fastmcpp/tools/manager.hpp" -#include "fastmcpp/tools/tool.hpp" - -#include -#include -#include -#include - -using namespace fastmcpp;

MSBuild's tracking system ran out of memory during compilation. Solution: Split part2 into part2a and part2b (~1,050 lines each): - interactions_part1.cpp (55 tests, 1,990 lines) - interactions_part2a.cpp (30 tests, 1,200 lines) - NEW - interactions_part2b.cpp (29 tests, 1,049 lines) - NEW - interactions_part3.cpp (50 tests, 1,742 lines) Total: 164 tests across 4 files (was 3 files). Windows CI error was: System.OutOfMemoryException in MSBuild TrackedVCToolTask File: fastmcpp_server_interactions_part2.vcxproj All 4 parts now compile and pass locally (4/4 tests, 0.07s).

Root cause: GitHub's windows-latest runners have only 16GB RAM, and parallel cl.exe processes exhaust memory with template-heavy code. Solution (based on Microsoft docs + community solutions): 1. Add `-A x64` to ensure 64-bit toolset (32-bit has ~2-3GB limit) 2. Use `/m:4` to limit MSBuild to 4 worker processes 3. Use `/p:CL_MPCount=1` to disable cl.exe's internal /MP flag This reduces peak compiler memory usage while still maintaining reasonable build performance (~4x parallelism at MSBuild level).
