[PATCH v2 0/4] MR6759: kernelbase: Make trailing slashes in CreateFileW set ERROR_PATH_NOT_FOUND
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=57376
-- v2: kernelbase: Make trailing slashes in CreateFileW set ERROR_PATH_NOT_FOUND kernel32/tests: Add another CreateFile test kernel32/tests: Only skip volume tests when access is denied kernel32/tests: Only skip volume tests on windows
From: Fabian Maurer dark.shadow4@web.de
Otherwise todo tests that already succeed will be skipped, we should always have access to volumes on Wine. --- dlls/kernel32/tests/file.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-)

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:

I believe this causes regression for some drivers that handle `IRP_MJ_CREATE` and may return `STATUS_FILE_IS_A_DIRECTORY` from there. `NtCreateFile()` is ***not*** just a wrapper for `open()`. For custom devices like `\.\MyCustomDriver`, it delegates to the third-party driver. The third-party driver might return `STATUS_FILE_IS_A_DIRECTORY` *but* still expect it to be translated to `ERROR_ACCESS_DENIED` even with the trailing slash. I suspect the real culprit is that `NtCreateFile()` is incorrectly translating Unix `EISDIR` to `STATUS_FILE_IS_A_DIRECTORY` *unconditionally*. In this case, the bug needs to be fixed in ntdll, not kernelbase.
I created a testcase here: https://bugs.winehq.org/attachment.cgi?id=77355
On windows, NtCreateFile returns `STATUS_FILE_IS_A_DIRECTORY` in both cases, same as Wine.
Not 100% sure how to best approach that driver issue, maybe check if the path starts with `\??\C:`?
Also, AFAIK we don't need to skip tests on wine, and on windows I got a false positive that I missed, so I tried improving the tests a bit.

Thanks. https://testbot.winehq.org/JobDetails.pl?Key=149442 seems to suggest that the status postprocessing is happening in kernelbase, not in ntdll.
Probably some compatibility logic for old DOS file API oddity.
Any news on this?
Original reporter, just pinging to see where this is at.
