From 012c8b307d339873bcdbbe95018ccfff904fc501 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 28 Mar 2024 14:08:47 -0700 Subject: [PATCH] t4126: make sure a directory with SP at the end is usable As afb31ad9 (t1010: fix unnoticed failure on Windows, 2021-12-11) said: On Microsoft Windows, a directory name should never end with a period. Quoting from Microsoft documentation[1]: Do not end a file or directory name with a space or a period. Although the underlying file system may support such names, the Windows shell and user interface does not. [1]: https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file and the condition addressed by this change is exactly that. If the platform is unable to properly create these sample patches about a file that lives in a directory whose name ends with a SP, there is no point testing how "git apply" behaves there on the filesystem. Even though the ultimate purpose of "git apply" is to apply a patch and to update the filesystem entities, this particular test is mainly about parsing a patch on a funny pathname correctly, and even on a system that is incapable of checking out the resulting state correctly on its filesystem, at least the parsing can and should work fine. Rewrite the test to work inside the index without touching the filesystem.
