ShellPkg: 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

ShellPkg/ShellCommandLib: add ShellSortFileList()

2021-01-19T18:23:28+00:00

Introduce the ShellSortFileList() function, for sorting an EFI_SHELL_FILE_INFO list, by FileName or by FullName. Duplicates can be kept in the same list, or separated out to a new list. In either case, the relative order between duplicates does not change (the sorting is stable). For the sorting, use OrderedCollectionLib rather than SortLib: - The PerformQuickSort() function from the latter has quadratic worst-case time complexity, plus it is implemented recursively (see "MdeModulePkg/Library/UefiSortLib/UefiSortLib.c"). It can also not return an error on memory allocation failure. - In comparison, the Red-Black Tree instance of OrderedCollectionLib sorts in O(n*log(n)) worst-case time, contains no recursion with the default PcdValidateOrderedCollection=FALSE setting, and the OrderedCollectionLib class APIs return errors appropriately. The OrderedCollectionLib APIs do not permit duplicates natively, but by using lists as collection entries, stable sorting of duplicates can be achieved.
