http://github.com/llvm/llvm-project/pull/95220 added a test with a very long file path, which can fail if run on Windows with a long directory path. On Windows, there are file path length limits, which can be worked around by prefixing the (absolute) path with '\\?\': https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation >From 80f06489a7dec38f683303bf023f02effc528ed9 Mon Sep 17 00:00:00 2001 From: Arthur Eubanks <[email protected]> Date: Mon, 25 Aug 2025 21:54:14 +0000 Subject: [PATCH] [clang-tidy][test] Make check_clang_tidy.py work with very long file paths http://github.com/llvm/llvm-project/pull/95220 added a test with a very long file path, which can fail if run on Windows with a long directory path.
