DLL separation for shell32
by Rolf Kalbermatter 14 Dec '02

14 Dec '02

Looking at shell32.dll I do see that it is the intention to get rid completely of any link time dependencies to ole32.dll for DLL separation. There are several late bound dependencies but I guess these are not any issue as they can not possible cause circular dependencies at load time. I have identified following direct dependencies from shell32 on ole32. location resolution pidl.c CLSIDFromString change to SHCLSIDFromString shell32_main.c CoCreateInstance change to internal late bound __CoCreateInstance shellole.c CoCreateInstance change to internal late bound __CoCreateInstance CLSIDFromString SHCLSIDFromString either link or forward to SHLWAPI_436 or create late bound CLSIDFromString shellord.c CoCreateInstance change to internal late bound __CoCreateInstance CoUninitialize create late bound CoUninitialize CoInitialize create late bound CoInitialize shellstring.c CoTaskMemFree create late bound CoTaskMemFree shlfldr_desktop.c CLSIDFromString change to SHCLSIDFromString The questions I have is, is it desirable to change those dependencies to late bound calls to OLE32, as there are already several in shell32.dll to remove any direct load dependency or does this only create additional problems? Also the remark in shlwapi.ordinal.c about SHLWAPI_436 that it must recode the function as the native DLL seems not to import ole32 or vice versa seems a bit strange. What if native also uses late binding for those functions? Rolf Kalbermatter

Fixing regressions (was: Re: OSS hang)

I just pinpointed the regression without understanding the code, and he wrote the proper fix. That was fun, by the way! I enjoyed learning how to hunt through CVS for what caused a problem to appear, and it was really gratifying to see an official patch so quickly as a result. Is there a list of other known application regressions? I might want to tackle one more. This seems like a good way for newbies to contribute. - Dan

Owner/permissions on system.reg etc
by Bill Medland 14 Dec '02

14 Dec '02

Before I waste hours on searching through the code can someone answer this? The way I like to run Wine is to have a single copy of system.reg and userdef.reg in a central location and then each user has a symbolic link to them (and the cached metrics) but a true copy of the user.reg. (I know that this is not going to work if multiple users simultaneously access it). However the ownership and permissions on the system.reg and userdef.reg change each time the wineserver runs. Presumably wine is actually creating new copies and relinking and this is why the ownership etc. changes. Would it be resonable at least to attempt to preserve the group permissions if not the whole ownership etc. -- Bill Medland

> I hoped to hear an improvement but there was no difference there's only a gain which is less than 0,4%, so I don't think you can hear it. and btw, some sounds package also do it this way (it's just a slighly faster than your proposal) so there's no urge to switch, but not harm either A+

My Windows headers don't include anything, but they are from an old VC++ version. Could someone with a newer VC++ check if this is still the case? -- Alexandre Julliard julliard(a)winehq.com

winewrap.c bombs when building on mingw
