- Make MPI REQUIRED for test builds (clearer error messages)
- Add project include directories to test_framework library
- Fix core_tests.cc to use custom framework correctly
- Fix mp_unit_tests.hpp to use mscclpp::test namespace
- Add FAIL() macro with streaming support for test messages
- Building tests now works in Docker environment with GPU bypass
Tests can now be built using:
docker run --rm -v $(pwd):/workspace -w /workspace \
ghcr.io/microsoft/mscclpp/mscclpp:base-dev-cuda12.4 bash -c \
"mkdir build && cd build && cmake -DMSCCLPP_BYPASS_GPU_CHECK=ON \
-DMSCCLPP_USE_CUDA=ON .. && make -j"

- Modified test/mp_unit/mp_unit_tests.hpp to use ../framework.hpp instead of gtest/gtest.h
- Enhanced test/framework.hpp with GTest-compatible APIs:
- Added Environment base class for global test setup/teardown
- Added TestInfo and UnitTest classes for test metadata access
- Added GTEST_SKIP macro support via SkipHelper class
- Added namespace alias 'testing' for compatibility
- Added InitGoogleTest and AddGlobalTestEnvironment helper functions
- Updated test/framework.cc with implementations for new classes
- All mp_unit test files now use framework.hpp through mp_unit_tests.hpp
- Formatting applied via lint.sh

* Added configurable InfiniBand (IB) signaling mode.
`EndpointConfig::Ib::Mode` enum selects the mode (`Default`, `Host`,
`HostNoAtomic`). `Default` is equivalent to `Host` unless specified
different by envrionment `MSCCLPP_IBV_MODE`. `Host` corresponds to the
previous implementation using RDMA atomics for signaling, while
`HostNoAtomic` uses write-with-immediate instead.
* Regarding updates in Python bindings and API.
* Added `port` and `gidIndex` field in the IB endpoint config (and
`deviceIndex` field for future usages)
* Added `MSCCLPP_IBV_SO` env variable to specify a custom libibverbs.so
* Added `--ib_gid_index` CLI option to `mp_unit_tests`
* Other minor fixes
The key purpose is handling all mscclpp objects' memory internally by
hiding shared pointers from user APIs.
* `Connection` class is now a wrapper of `BaseConnection` class that is
equivalent to the previous `Connection` class
* `connect()` methods now return `Connection` instead of
`std::shared_ptr<Connection>`
* Removed `connectOnSetup()` method
Change to use smart pointer for IB structure. Registered memory will own
ibMr, ibCtx will not held the reference
- Use smart pointer for IbQp and IbMr
- Update memoryChannel API, keep localRegisteredMemory
- Close fd when registedMemory released

* Renamed `ProxyChannel` -> `BaseProxyChannel` and `SimpleProxyChannel`
-> `ProxyChannel`. It makes the interface more consistent by defining
channels to be associated with a certain src/dst memory region:
`ProxyChannel` as "sema + src/dst + fifo" and `SmChannel` as "sema +
src/dst". BaseProxyChannel is not associated with any memory regions, as
"sema + fifo".
* `ProxyChannelDeviceHandle` now inherits from
`BaseProxyChannelDeviceHandle`, instead of having one as a member.
