New Revision: 54309
URL: http://svn.reactos.org/svn/reactos?rev=54309&view=rev
Log:
[KERNEL32]: Move path-related APIs away from dir.c, and into path.c instead.
[KERNEL32]: Fix SetDllDirectoryW:
- Fail if ";" is in path
- Use RtlCreateUnicodeString instead of manual string management -- if the allocation
fails, do not free the current base directory string! Older API would always free the
current directory string, even if setting up the new one failed.
- Don't assume lpPathName is filled out, it can be NULL, and this means the DLL
directory should be cleared.
[KERNEL32]: Fix SetDllDirectoryA as above, additionally use RtlInitAnsiStringEx to protect
against overflow, and use Basep8BitStringToUnicodeString, to add support for OEM paths
instead of assuming ANSI.
[KERNEL32]: GetDllDirectoryW: correctly NULL-terminate and check lengths
[KERNEL32]: GetDllDirectoryA: same as above, plus use BasepUnicodeString* APIs to
correctly support OEM paths instead of assuming ANSI.
[KERNEL32]: NeedCurrentDirectoryForExePath(A/W): call internal
BasepIsCurDirAllowedForPlainExeNames instead of converting from A->W, this isn't
needed.
[KERNEL32]: GetFullPathNameW just calls RtlGetFullPathName_U, no extra checks/etc are
needed.
Next steps are GetFullPathNameA, GetShort/LongPathNameA, GetShort/LongPathNameW, hoping to
bring the wine test failures closer to zero.
