[zware]

This is the same underlying issue as #118773, isn't it?

[eryksun]

Win32NtTests.test_stat_inaccessible_file() incorrectly depends on the localized name of the well-known group "Everyone". It would need to use the SDDL alias *WD.

Actually the test should be implemented differently by denying synchronize (S) access to users (*BU), like StatAttributeTests.test_access_denied() (which is a redundant test now). However, this can only test the slow path of os.stat(), which depends on opening the file with SYNCRHONIZE | FILE_READ_ATTRIBUTES access. That's the minimum access that can be requested via CreateFileW(). If that minimum level of access is denied, the slow path of os.stat() falls back on the parent directory entry from FindFirstFileW().

The fast path of GetFileInformationByName() or GetFileAttributesW() doesn't need the right to synchronize on the file. It only needs read-attributes (RA) access, but there's no meaningful way to deny that access for this test. If read-attributes access isn't allowed explicitly for a file, or if read-attributes access is explicitly denied, then it's still implicitly allowed as long as read-data access (i.e. list-directory access) is allowed for the parent directory.

I tried #118800 before submitting this issue, and that PR did not resolve it, so it seems like a different problem to me.

Same root cause (localised account names), but different code.

Yeah, this is known - it's why the test checks for either 0 or st_ino/dev, because if we take the faster path we'll get them. So eventually the test becomes redundant, but until then it helps verify that we aren't returning garbage in certain fields (which was the bug that prompted it).

It would need to use the SDDL alias *WD.

This seems to work fine, PR incoming.
