[Bug 18924] New: OutputDebugString does not do what it's supposed to do

http://bugs.winehq.org/show_bug.cgi?id=18924

Summary: OutputDebugString does not do what it's supposed to do
           Product: Wine
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

OutputDebugString seems to be "invisible" to other apps in wine, it just prints
a message to the terminal. I saw a mailing list discussion about this problem
but I got the impression this wasn't going to be changed anytime soon (because
it's "good enough"). Well, it isn't.

As wrong as it may be, some programs rely on parsing other programs debug
output, and this breaks down in wine. The specific application I'm having
trouble with is FF7Music, some hack that uses debug output to replace the music
in Final Fantasy VII.

A fix for this would be greatly appreciated.

OutputDebugString() in Wine prints nothing unless a debug output is requested.

Hello,

the reporter probably requests OutputDebugString() to be working as Windows
does.

There are many articles how the data is passed between application and
debuggers/monitors (using 4K shared memory and sync objects).

http://www.codeproject.com/KB/winsdk/OutputDebugString.aspx

Currently OutputDebugString() passes data straight to Wineserver not respecting
any debug message monitor that might have created DBWIN_* objects.

Regards

It's not clear at all from the original bug report what the reporter
complains about, and what exactly is the functionality is needed, and
is that really about OutputDebugString sending info to the debugger.

I think it was pretty clear as he described the current OutputDebugString()
behaviour and apps which act as "debug message monitor" relying on proper
implementation to actually "see" the debug messages.
A simple string dump on main executable (after unpacking with UPX) reveals:

--- snip ---
$ strings FF7Music.exe  | grep DBWIN
DBWIN_BUFFER_READY
DBWIN_DATA_READY
DBWIN_BUFFER
--- snip ---

So yes, the app relies on proper OutputDebugString() implementation which Wine
currently lacks.

The current implementation can be enhanced by keep sending the message buffer
to Wineserver - preserving existing interaction with usermode debuggers - _and_
write the message buffer into shared section if present.

Some tools that can be used for testing (in addition to the link from my
previous comment):

"DebugView" from infamous sysinternals team (now M$):

Please reset, Wine sends debug strings to monitor now.
