UnitTestFrameworkPkg: Replace include guards with #pragma once

2026-02-23T21:01:28+00:00

Replace traditional `#ifndef`/`#define`/`#endif` include guards with `#pragma` once. `#pragma once` is a widely supported preprocessor directive that prevents header files from being included multiple times. It is supported by all toolchains used to build edk2: GCC, Clang/LLVM, and MSVC. Compared to macro-based include guards, `#pragma once`: - Eliminates the risk of macro name collisions or copy/paste errors where two headers inadvertently use the same guard macro. - Eliminate inconsistency in the way include guard macros are named (e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.). - Reduces boilerplate (three lines replaced by one). - Avoids polluting the macro namespace with guard symbols. - Can improve build times as the preprocessor can skip re-opening the file entirely, rather than re-reading it to find the matching `#endif` ("multiple-include optimization"). - Note that some compilers may already optimize traditional include guards, by recognzining the idiomatic pattern. This change is made acknowledging that overall portability of the code will technically be reduced, as `#pragma once` is not part of the C/C++ standards. However, this is considered acceptable given: 1. edk2 already defines a subset of supported compilers in BaseTools/Conf/tools_def.template, all of which have supported `#pragma once` for over two decades. 2. There have been concerns raised to the project about inconsistent include guard naming and potential macro collisions. Approximate compiler support dates: - MSVC: Supported since Visual C++ 4.2 (1996) - GCC: Supported since 3.4 (2004) (http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html) - Clang (LLVM based): Since initial release in 2007 Signed-off-by: Michael Kubacki

UnitTestFrameworkPkg/MemoryAllocationLibPosix: Add allocate below address

2025-01-21T05:02:38+00:00

Add HostMemoryAllocationBelowAddressLib class and implementation that uses OS specific services to perform pool and page allocations below a specified address in a host based unit test application execution environment. This library class is only required for mocking buffers that are assumed to be below a specific address by code under test. Signed-off-by: Michael D Kinney

UnitTestFrameworkPkg/MemoryAllocationLibPosix: Add DEBUG_CLEAR_MEMORY()

2025-01-21T05:02:38+00:00

Add use of DEBUG_CLEAR_MEMORY() macros on all allocation and free operations in MemoryAllocationLibPosix to match behavior of all other MemoryAllocationLib instances. Signed-off-by: Michael D Kinney

UnitTestFrameworkPkg/Library: Add library instances

2020-02-07T19:18:53+00:00

https://bugzilla.tianocore.org/show_bug.cgi?id=2505 Add the following library instances that are used to build unit tests for host and target environments. * CmockaLib with cmocka submodule to: https://git.cryptomilk.org/projects/cmocka.git * DebugLibPosix - Instance of DebugLib based on POSIX APIs (e.g. printf). * MemoryAllocationLibPosix - Instance of MemoryAllocationLib based on POSIX APIs (e.g. malloc/free). * UnitTestBootLibNull - Null instance of the UnitTestBootLib * UnitTestBootLibUsbClass - UnitTestBootLib instances that supports setting boot next to a USB device. * UnitTestLib - UnitTestLib instance that is designed to work with PEI, DXE, SMM, and UEFI Shell target environments. * UnitTestLibCmocka - UintTestLib instance that uses cmocka APIs and can only be use in a host environment. * UnitTestPersistenceLibNull - Null instance of the UnitTestPersistenceLib * UnitTestPersistenceLibSimpleFileSystem - UnitTestPersistenceLib instance that can safe the unit test framework state to a media device that supports the UEFI Simple File System Protocol. * UnitTestResultReportLibConOut - UnitTestResultReportLib instance that sends report results to the UEFI standard output console. * UnitTestResultReportLibDebugLib - UnitTestResultReportLib instance that sends report results to a DebugLib using DEBUG() macros.
