Fixed with a compatibility branch for MSVC’s traditional preprocessor. The original counters, dispatch macros, and optional-value helpers are preserved. No CMake source changes.

Fresh Windows build explicitly used /Zc:preprocessor-:

Credential tests: 17 passed
S3 refresh and expiry cases: 2 passed
git diff --check: passed

Commands verified:

ctest --test-dir build/windows-credential-macros -R '^flb-it-aws_credentials_http$' --output-on-failure

$env:FLUENT_BIT_BINARY=(Resolve-Path build/windows-credential-macros/bin/fluent-bit.exe).Path

📝 Walkthrough

Credential URI validation now uses exact protocols and approved hosts. AWS credential tests cover host validation and cross-platform setup. Mock argument handling supports traditional MSVC preprocessors. The integration manager uses Windows-specific process startup and shutdown behavior.

Changes: AWS credential HTTP

Layer / File(s)	Summary
Credential URI validation and coverage `src/aws/flb_aws_credentials_http.c`, `tests/internal/aws_credentials_http.c`	Credential validation accepts HTTPS and restricts HTTP to approved hosts and addresses. Greengrass `localhost` is normalized to `127.0.0.1`. Tests cover accepted and rejected URIs and use cross-platform environment setup.
Variadic mock argument handling `tests/include/aws_client_mock.h`, `tests/internal/aws_credentials_http.c`	The mock macros support traditional MSVC argument counting and derive response and configuration counts from compound-literal sizes. Tests cover zero, one, and two optional values.

Windows integration process handling

Layer / File(s)	Summary
Windows process start and shutdown `tests/integration/src/utils/fluent_bit_manager.py`, `tests/integration/tests/test_fluent_bit_manager.py`	On Windows, the manager starts Fluent Bit with Windows-specific process options and uses a console control event for shutdown. Tests check platform-specific signal handling, shutdown errors, cleanup, and executable path resolution.

tests/internal/aws_credentials_http.c: 1
214-214: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

TEST_ASSERT leaks config on failure.

TEST_ASSERT(provider != NULL) aborts the test function when provider creation fails. It does not call flb_config_exit(config). The old code released the config. The leak occurs only in the failure path, so the impact is low. Other tests in this file use the same pattern.

Update the failure path after provider creation in this test so config is
released with flb_config_exit(config) before the assertion aborts; preserve the
existing provider validation and cleanup behavior.

Review comments at @tests/integration/src/utils/fluent_bit_manager.py:
- Line 275: Update stop() around _send_windows_shutdown so an
AttachConsole-related failure is ignored only when a fresh process-state poll
confirms Fluent Bit has exited; preserve propagation of other helper failures.
Ensure the process-state reset and output-handle cleanup still run after this
race, while retaining existing behavior when the process remains alive.
- Around line 317-319: Update the shutdown sequence around AttachConsole,
SetConsoleCtrlHandler, and GenerateConsoleCtrlEvent so each Windows API call
executes independently of assertions, including when Python optimization is
enabled. Check each return value explicitly while preserving the existing
ctypes.get_last_error handling.
