[Bug 40935] New: CreateProcess returns empty handler

https://bugs.winehq.org/show_bug.cgi?id=40935

Bug ID: 40935
           Summary: CreateProcess returns empty handler
           Product: Wine-staging
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

      Distribution: ---

Hope this is the right place to place this bug.

For a simple and fast example, use the one from here:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms682512(v=vs.85).a...

Problem: After calling CreateProcess, the PROCESS_INFORMATION is empty with no
handlers at all (everything is initialized with 0), GetLastError() is 0, the
process is created and executed, but we have no way of knowing when it ends
cause there is no handler.

Compiled using vs9 on Win7 prof. Works great.
Executed on linux using wine (tried with 1.6 and winehq-staging), runs but the
handlers are empty.

The example is working fine here (compiled with i686-w64-mingw32-gcc). I tested
with Wine 1.9.13, but I would expect the same result with 1.6. Wine also uses
CreateProcess internally and such a critical error would render basically all
applications useless.

Are you by any chance passing a Linux path to CreateProcess? This would explain
the problem because it is not fully supported (yet). Otherwise, please provide
more details how exactly to reproduce this issue, and which fields are not set
as expected.

There is no problem with the path. For example I am testing it by running ls
command in the example and in both cases (linux path and win path), i receive
the output from ls

I've tested with i686-w64-mingw32-gcc as well. But same results. It compiles,
it runs, it displays the result from the command run in CreateProcess, but the
PROCESS_INFORMATION is still empty.

Is there anything that I should install or set in order to get more
informations?

As already mentioned, for Linux programs (including the Linux "ls" command)
this is kinda expected. They are not launched with Wine, which means Wine has
no control and they run independently.

It would be interesting to know if you have found a possibility to reproduce
this with a Windows or Wine program - for example winecfg.exe, wineconsole.exe.

Thank you for the fast reply and I sorry, it seams I didn't understood what
exactly you meant before.

You are right, if it is a process such as winecfg.exe (or notepad.exe), then
there doesn't seem to be any problem.

One last question, when do you think there might be support for this?

Thanks for confirming that this is a problem with UNIX processes only.
Unfortunately I am not aware of anyone working on this at the moment.

May I ask why exactly you need this feature? For interaction with native UNIX
programs, the preferred way is to compile your application with winegcc, and
then to directly use fork()/exec().

Unfortunately I can't say much. The application uses other non-binary program
such as python, perl, etc. to run various scripts. But now that I understand
the main problem I can find a way around it.
