RtlNtStatusToDosError issue
by Bill Medland 07 Nov '01

07 Nov '01

Can I solve this through documentation or do I have to use debug? I am implementing the LockFile stuff based on what Alexandre did to the CorelWine last year. Currently I have it returning error codes such as ERROR_LOCK_VIOLATION. However that causes RtlNtStatusToDosError to complain about not recognising it (no big surprise) during the server call. What is the correct solution? To choose a status at random that translates to ERROR_LOCK_VIOLATION? Bill

What's happened to www.winehq.com/ident
by Bill Medland 07 Nov '01

07 Nov '01

Anyone know what has happened to the LXR stuff? I used to use it to find where files are implemented but now the symbols don't seem to be indexed any longer. Bill

[EXPERIMENTAL PATCH]: Winsock2
by Martin Wilck 07 Nov '01

07 Nov '01

Hi, this patch tries to implement a small part of the extended Winsock 2 functionality in Wine. It is very experimental, I have only made sure everything compiles. It is _NOT_ intended for people to try and run. I am submitting this patch because I am pretty new to Wine hacking and I'd appreciate some Wine gurus to audit this for obvious stupidity, style incompatiblities, etc. Features implemented: - WSAAccept(), including callback functionality. - WSASocket(): support for dwFlags parameter. The real difficult stuff will follow when I start looking into WSARecv(), WSASend(), and WSAGetOverlappedResults(). Thus it'd be nice if someone pointed out my misconceptions before I put real work into the latter.

Not if they are changed permanently; if we want them to be reset then we simply should not set them and always query X. Basically there are many possibilities: 1) get and set in registry, ignore X 2) get and set in registry, if nothing in registry get default value from X 3) always get from X, ignore registry, do nothing on set 4) always get from X, ignore registry, set X value on set (not recommended) and there are even more combinations if you differentiate setting permanently/temporarily. There is no single right answer, it all depends on what the parameter does. IMO most cases should do 1), but there can be exceptions. > One case which comes to mind when such integration > would be useful is system parameter which shows > whether mouse buttons are swapped.

In this case I don't think we should query X at all, since if the buttons are swapped at the X level this is transparent for us. Otherwise the buttons will get swapped twice... -- Alexandre Julliard julliard(a)winehq.com

The X settings should probably be loaded lazily just like the rest. Just check if the registry key exists already to find out if you need to get the value from X. Another possibility is to have the X driver set the registry values on startup; this may actually be cleaner since then you don't need to add new calls to the USER driver. Also I'm not convinced there are many cases where we actually need to get proper values from X; what cases do you have in mind? > Other issue is fixed with this approach - the values > in registry are not changed back to X settings on > startup of new Wine process. > > Alexandre, the submitted patch is not affected by this > issue because none of the system parameters there is > initialized from X settings. > > Do you have any other concerns about the patch?
