ipc, refactor: Update mp::g_thread_context references

This is a small internal code cleanup in Bitcoin Core's inter-process communication (IPC) code. It replaces direct references to a global thread-local variable with a helper function so the code works around a compiler bug in Windows MinGW…

ipc, refactor: fix include order

This is a purely cosmetic code cleanup that reorders #include lines in a single source file. It moves two standard C++ library headers (<utility> and <vector>) to sit with the other standard headers, separate from POSIX system headers. The…

This is a small defensive code change in Bitcoin Core's inter-process communication (IPC) code. It reorders two class member variables so that the event loop is destroyed before the background thread that runs it. The commit message says t…

ipc, refactor: use native path separators in test

This is a small test-only cleanup that changes hardcoded Unix-style forward slashes in a test file to use the operating system's native path separator. It does not change any production code or fix a security bug.

ipc: Avoid 'unistd.h' error with MSVC

ipc # build: Fix fuzz target CMakeLists.txt for external libmultiprocess

This is a one-line build-system fix for a Bitcoin Core fuzz-testing target. It changes a CMake target name so the correct header paths are found when libmultiprocess is built externally instead of bundled. It does not change runtime behavi…
