[PATCH 1/2] kernel32/path: Allow renaming a file/directory to a different capitalization of itself
Renaming a file or directory from foobar to FooBar (or any other caps-only change) should work and capitalize it, like on Windows, instead of being a no-op.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=46203 Signed-off-by: Gabriel Ivăncescu gabrielopcode@gmail.com ---
Currently Wine simply finds the existing foobar and thus "changes" it from foobar to foobar, which is a no-op and wrong. This is especially annoying with file managers when trying to rename files to different capitalization...
The __wine_wcstoumbs thing is taken from the similar __wine_init_codepages layout used in locale.c. I've had to do it this way and export it because accessing the ntdll_wcstoumbs internal function is required here to build the filename in its original capitalization, untouched.
I am aware that the extern function declaration may not be acceptable, but I made it similar to __wine_init_codepages since this function should not really be declared in other headers, in my opinion. Unless, of course, there's a better way to do this.

Hi,
While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

ntdll: pipe.c:1557: Test failed: pipe is not signaled pipe.c:1557: Test failed: pipe is not signaled
Looks like a random error / pre-existing failure to me. I don't see how the patch would affect the pipe signal and I don't even get it on my machine.

Ok, I confirmed these tests are pre-existing. Earlier I sent it to the testbot and it all succeeded, see:
https://testbot.winehq.org/JobDetails.pl?Key=45094
I submitted a dummy test and it also succeeded:
https://testbot.winehq.org/JobDetails.pl?Key=45130
So it looks like some random failure to me and not based on the patch.
I know the patch most likely will need some tweaking with the extern function declaration thing. Can someone please provide some feedback for it?
