            Bug ID: 59340
           Summary: Win32 streams support (filename:streamname:$DATA)
           Product: Wine
           Version: unspecified
          Hardware: Other
                OS: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntoskrnl
          Assignee: [e-mail]
          Reporter: [e-mail]

We need Win32 streams support (filename:streamname:$DATA) in Wine to support
those applications which use them (i.e. INDB, MS SQL, SIEMENS PLC simulators,
BOSCH/REXROTH PLC, ... software).

It depends on the application, and the error messages are not straightforward
because the people writing the software didn't expect that Win32 streams are
not available on Windows.

SIEMENS PLC software for example just randomly throws up a "Write error"
dialog, and refuses to work. If you look at that with the drstrace.exe tool
from DrMemory you see it wants to create a file bbc.dat:bitmap:$DATA, which
fails with Wine.

BOSCH/REXROTH software just refuses to start, with no message whatsoever.
Looking at that with drstrace.exem, you see it wants to create
simdat.bundle:rexroth_simindex:$DATA (which is some kind of sparse file, always
512GB in sizem, but very little data allocated (4-5 MB).

As far as I can tell, Wine doesn't include support for NT streams per se, but
it also doesn't recognize them either. If the application tries to create a
file with that format, Wine will just create it as a separate file. A simple
test confirms this. What exactly is going wrong? Can you attach a log with
WINEDEBUG=+file,+server,+pid ?

This does not help. You still need support for FileStreamInformation and
FileStreamInfo, and you need name aliasing for the "default stream". For
example filename "abc::$DATA" is an alias for "abc", and most applications
using streams also use the default stream alias.
