           Summary: winecfg fails to initialize kernelbase.dll

winecfg fails to initialize on an empty prefix, with the following message:

000d:err:module:LdrInitializeThunk "kernelbase.dll" failed to initialize,
aborting

Using bisect I traced the error to the following commit:

commit 036f4dca3c7f9ee8964bb4ae0c4bcd106a347c7b
Author: Alexandre Julliard <julliard(a)winehq.org>

    winecrt0: Rebuild the argv array instead of getting it from libwine.

After studying the debug output I found that the process of kernelbase.dll
initialization is strange. First time the trace output comes from 64-bit
version:

000f:trace:module:MODULE_InitDLL (0x7b010000
L"kernelbase.dll",PROCESS_ATTACH,0x32fb00) - CALL
000f:trace:module:LdrGetDllHandle L"kernel32.dll" -> 0x7b420000 (load path
L"C:\\windows\\system32;C:\\windows\\system32;C:\\windows\\system;
000f:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x1004,000000000032E38C,2)
000f:trace:module:FindResourceExW 000000007B420000 #0006 #0101 0409
000f:trace:module:LoadResource 000000007B420000 000000007B4D83B0
000f:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x1004,000000000032E38C,2)
returning number 1252
000f:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x1011,000000007B0DBBE0,2)

And the second time the output looks like coming from 32-bit code:

000d:trace:module:MODULE_InitDLL (0x7b010000
L"kernelbase.dll",PROCESS_ATTACH,0x32fd24) - CALL
000d:trace:module:LdrGetDllHandle L"kernel32.dll" -> 0x7b410000 (load path
L"C:\\windows\\system32;C:\\windows\\system32;C:\\windows\\system;
000d:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x1004,0032E748,2)
000d:trace:module:FindResourceExW 7B410000 #0006 #0101 0409
000d:trace:module:LoadResource 7B410000 7B4B6EF4
000d:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x1004,0032E748,2) returning
number 1252

(note narrower integer values)

Before the commit in question all the output from MODULE_InitDLL looks
identical.

The exact reason of initialization failure is because FILE_CreateFile() returns
STATUS_OBJECT_PATH_NOT_FOUND instead of STATUS_OBJECT_NAME_NOT_FOUND when
looking for sortdefault.nls:

000d:trace:ntdll:FILE_CreateFile handle=0x32e45c access=80000000
name=L"\\??\\C:\\windows\\globalization\\sorting\\sortdefault.nls"
objattr=00000000 root=(nil) sec=(nil) io=0x32e3e8 alloc_size=(nil)
attr=00000000 sharing=00000001 disp=1 options=00000010 ea=(nil).0x00000000
000d:trace:file:wine_nt_to_unix_file_name
L"\\windows\\globalization\\sorting\\sortdefault.nls" not found in
/tmp/mock/dosdevices/c:/windows
000d:warn:ntdll:FILE_CreateFile
L"\\??\\C:\\windows\\globalization\\sorting\\sortdefault.nls" not found
(c000003a)

Because of this the code in open_nls_data_file in dlls/ntdll/locale.c does not
look in the WINEDATADIR for the file and returns overall failure. Compare to
the previous, successful call:

000f:trace:ntdll:FILE_CreateFile handle=0x32dfb8 access=80000000
name=L"\\??\\C:\\windows\\globalization\\sorting\\sortdefault.nls"
objattr=00000000 root=(nil) sec=(nil) io=0x32ded0 alloc_size=(nil)
attr=00000000 sharing=00000001 disp=1 options=00000010 ea=(nil).0x00000000
000f:trace:file:wine_nt_to_unix_file_name
L"\\windows\\globalization\\sorting\\sortdefault.nls" not found in
/tmp/mock/dosdevices/c:/windows/globalization/sorting/sortdefault.nls
000f:warn:ntdll:FILE_CreateFile
L"\\??\\C:\\windows\\globalization\\sorting\\sortdefault.nls" not found
(c0000034)

(Note a different status code returned and that wine_nt_to_unix_file_name()
looks for the file in the correct place)

I was unable to find out why exactly this happens, the commit in question does
not seem to touch anything that may cause the issue.

winecfg works if called with "wine64 winecfg", but unfortunately running Win32
programs is not possible either with "wine" or "wine64" - failing with the same
error, so I consider the bug critical.

The bug can be worked around by manually copying nls/sortdefault.nls to
$WINEPREFIX/drive_c/windows/globalization/sorting/ - or using wine on a prefix
initialized by a working version. It does not reproduce on wine64-only install
(which cannot run Win32 application by design), and though "wine64 winecfg"
works - it doesn't add the windows/globalization/sorting/sortdefault.nls or
other NLS files any more.

The full trace log of winecfg which ends with the error is attached.
