Re: Possible minor bug in Git




Setting `true` as the default for GIT_ICASE_PATHSPECS_ENVIRONMENT, when git is built on a Windows system, solves the bug.

	diff --git a/pathspec.c b/pathspec.c
	index 12c2b322b3..906cf24e3e 100644
	--- a/pathspec.c
	+++ b/pathspec.c
	@@ -237,7 +237,11 @@ static inline int get_icase_global(void)
		static int icase = -1;

		if (icase < 0)
	+       #if defined(GIT_WINDOWS_NATIVE) || defined(__CYGWIN__)
	+               icase = git_env_bool(GIT_ICASE_PATHSPECS_ENVIRONMENT, 1);
	+       #else
			icase = git_env_bool(GIT_ICASE_PATHSPECS_ENVIRONMENT, 0);
	+       #endif

		return icase;
	 }

Unfortunately that fix introduces a regression too, tested in t/t3700-add.sh --- `error out when attempting to add ignored ones but add others`.

I already spent some time to understand why, but got no luck: I have to dive deeper into the source code.

In case I can fix the regression, is changing the default value of that env variable a good solution? Should I change the approach?

Like leveraging core.ignorecase somewhere ...?

Thanks,
