Multiuser database application / file locks

tilolevante · Post by **tilolevante** » Tue Mar 08, 2011 2:48 pm

Hi,

I have an old dbase application. The application works well under wine.
But if I use it with several users, the database is damaged.
File locks do not work properly.

If I start the application several time with one uid, the database is ok.

Is there a way, to get proper file locks with wine?

Thanks for any hints

Yes, run it under same user same wineprefix. Wine can't support proper file locking between different users/wineprefixes. Wine is a single user application.

I tried this already, it works well for the file lock. But the windows focus is a problem:

Example: Two users start the app with the same wineprefix and uid (using sudo). Flie locking is fine.

If the first users tries to enter a text and the second user klicks on a window, then the first user looses the window focus and can not type anymore.

That's interesting... I don't know if Wine has ever been tested with
different instances of an app running together with different DISPLAYs.

Try filing a bug report at bugs.winehq.org.

It's not supported, and there are bugs for this already.
