After working prefectly for over 2 years SimCity 3000 is broken.
The patch that broke it is http://www.winehq.org/hypermail/wine-cvs/2005/03/0098.html
basicly the problem is simple. The source and the destination are both the same surface in DIB_DirectDrawSurface_Blt() and with the new locking in place the destination never gets updated. So althought it might fix Picasa2 it is definatly not correct.

Hi Tony,
I don't know why I'm cc-ed. I only fixed another regression ;-). I don't known anything about locking, so Matt?
Cheers,
Paul.

I think the problem is that we lock both the src and dest surfaces, without checking to see if they are the same. I think we then try to lock both surfaces and one of the locks fails.
Perhaps this might be a better solution:
if (src == iface) { DD_STRUCT_INIT(&ddesc); DD_STRUCT_INIT(&sdesc);
IDirectDrawSurface7_Lock(iface,NULL,&ddesc,0,0);
DD_STRUCT_COPY_BYSIZE(&ddesc,&sdesc); } else { DD_STRUCT_INIT(&ddesc); DD_STRUCT_INIT(&sdesc);
sdesc.dwSize = sizeof(sdesc); if (src) IDirectDrawSurface7_Lock(src, NULL, &sdesc, DDLOCK_READONLY, 0); ddesc.dwSize = sizeof(ddesc); IDirectDrawSurface7_Lock(iface,NULL,&ddesc,DDLOCK_WRITEONLY,0); }
I don't have access to my box with my Wine tree right now so I don't know if this will compile. Note that the fix will need to be done for both _Blt() and _BltFast().

DDLOCK_NOSYSLOCK prevents DirectDraw from locking "system lock", which is a global 16-bit lock on Windows 9x systems. I don't think this is the right way to fix this.

This flag has no effect on Windows 2000 or Wine, since they don't have global Win16 locks (AFAIK).

Whoops - I guess Wine does have the same system-level mutex. :) I just read through the syslevel documentation on WineHQ.
Since the DirectDraw stuff doesn't seem use the Wine syslevel (from a cursory examination), I suppose the flag is still a noop.

AFAICS The locking system that you have put in place is exactly that: a "system lock". Not "global 16-bit" perhaps but it definatly is a system lock.
I am fairly familiar with how this program operates. It is the program itself that is calling the locks with this flag and this is the only way I can see it can work with the system that you have put into place.
The bottom line here I have a problem with the locking system you have put into place since it breaks my favorite program. Please try the patch and see if it works for your program. If it does then we/I can work up a patch that works with your program and mine. If you are not willing to look at it am perfectly willing to submit a patch that removes your patch since it is clearly incorrect as it stands.
Please let's work together on this.

The locking system is actually a per-surface lock. Basically, DirectDraw under Windows requires you to lock a surface in memory before blitting to it. Wine doesn't strictly enforce this locking requirement, but some programs rely on the correct state behaviour.

I'm not trying to be difficult, don't worry. :)
I can take a look at it, but, as I mentioned earlier, I don't currently have access to the machine to compile/test. Could you try out the change I posted earlier that changes the locking behaviour when src == dest? I haven't seen any followup mentioning whether that worked or not, but from what you've mentioned it sounds like it should solve the problem. It's a pseudo-patch, but it should be pretty obvious which part of the Blt() function to apply it to.
I'll cook up a patch to implement my locking behaviour fix in Blt and BltFast, but it'll have to wait a couple of hours. I can also see if I can find a demo version of SimCity 3000 to try out.

I think that it really doesn't matter, we can argue symantics forever. What I am really concerned with is that these programs run.

I tried putting in the patch as you demonstrated and I could not get it to work (get the proper behavior from SimCity 3000). That is why I came back with the patch that I did. It is possible I did not understand your intent so I would be happy to try a real patch from you.

I ran the Sim City 3000 demo and traced the problem down to _Blt() failing to release a lock if an invalid rectangle is passed to it. The attached patch should fix a number of correctness problems, including this one. Give it a shot and let me know if it fixes things for you.
I checked both SC3000 and Picasa 2 and both continue to work after this patch is applied.

works much better for me (insted of the single BOOL locked). After looking at the code more I was wondering why you could not have used lastlock type for locking. If that is not possible I would suggest that instead of locked_read and locked_write you could use DWORD locktype.
