[PATCH resend] ntdll: Allow renaming a file/directory to a different case of itself.

Renaming a file or directory from e.g. foobar to FooBar (or any other case change) should work, like on Windows, instead of being a no-op. Clobbering an existing file must also respect the new case. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=46203 Signed-off-by: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> --- To simplify the code and avoid another trailing slash quirk, the case is not sent if the conversion fails (which keeps current behavior), because it should be very rare in practice so it's not worth the extra complication that doesn't really bring any benefit to begin with. Note that the server has to check for caselen == 0; it's not due to errors, it's due to the path mapping to a device or unix root directory. In this case, there is no such thing as "last component" because there are no components at all, so obviously there's no case to replace with. Handling the rare error above with the same code is just an implicit side effect without adding any extra code, so I see it as a bonus. dlls/kernel32/tests/file.c | 4 +- dlls/ntdll/tests/file.c | 4 +- dlls/ntdll/unix/file.c | 72 ++++++++++++++++++++++++-- server/fd.c | 100 +++++++++++++++++++++++++------------ server/protocol.def | 2 + 5 files changed, 142 insertions(+), 40 deletions(-) diff --git a/dlls/kernel32/tests/file.c b/dlls/kernel32/tests/file.c index ea0a32f..15bfc13 100644 --- a/dlls/kernel32/tests/file.c +++ b/dlls/kernel32/tests/file.c @@ -2040,7 +2040,7 @@ static void test_MoveFileA(void) ok(hfile != INVALID_HANDLE_VALUE, "FindFirstFileA: failed, error %d\n", GetLastError());
