Problems with rsaenh/advapi32 and 'Myst Uru Demo'
by Paul Vriens 20 Feb '05

20 Feb '05

Hi, I've download a bunch of demo-apps and this one (http://www.gamershell.com/news/10306.html) has some problems with the builtin rsaenh.dll/advapi32.dll. The trace (+crypt,+loaddll) shows: fixme:crypt:CRYPT_VerifyImage (rsaenh.dll, 0x77e39320): not verifying image trace:crypt:RSAENH_CPAcquireContext (phProv=0x77e3941c, pszContainer="{07EC3FFA-8373-11D9-C687-000CF1342294}", dwFlags=00000010, pVTable=0x77e394d0) trace:crypt:CryptReleaseContext (0x77e38c68, 00000000) trace:crypt:RSAENH_CPReleaseContext (hProv=00000001, dwFlags=00000000) trace:loaddll:MODULE_FlushModrefs Unloaded module L"c:\\windows\\system\\rsaenh.dll" : builtin trace:crypt:CryptDestroyHash (0x77e38c48) wine: Unhandled exception (thread 000d), starting debugger... Is this due to the 'lack' of reference counting in the advapi32 crypt stuff? It looks like RSAENH_CPReleaseContext released 'everything' where it shouldn't, hence the failure of CryptDestroyHash. Cheers, Paul.

wpp
by Ge van Geldorp 20 Feb '05

20 Feb '05

wpp will currently silently drop non-preprocessor stuff (typedefs, function prototypes etc.) when #including a .c or .h file. However, if you preprocess e.g. a .rc file externally and then feed it to wrc (which in turn will feed it through wpp) the non-preprocessor stuff isn't removed. The patch below changes that, by looking at the filename on the #line directive. If it ends in .c or .h, no output is generated (but the file is still parsed for preproc statements ofcourse). We need this for ReactOS, it doesn't hurt Wine (yes, I've tested it <g>) and including it in Wine would make my monthly job of merging Wine and ReactOS a tad easier. If there are no objections I'll submit to wine-patches in a few days. We also have another change in wpp, which adds support for #include_next (can't take credit for that, Filip Navara wrote it). Since you can't use that #include_next in Wine anyway (not every compiler supports it) I'm not going to bother creating and testing a Wine patch for it. If I misjudged and there is interest in this from the Wine side just let me know. Ge van Geldorp.

idea to spot regressions
by Jonathan Ernst 19 Feb '05

19 Feb '05

Hi everyone, I'd like to know what you people think about this idea for the application database: When an application version goes from gold to silver or silver to bronze for example, the AppDB asks the maintainer if he wants to inform wine developpers about this regression and if yes the maintainer has a field where he can enter some comments about the regression and the AppDB sends an e-mail to wine-devel with links to the AppDB entry and the maintainer's comments. This would ease the task for maintainer to report regressions and for developpers to know about them. Looking forward to reading your comments. Jonathan

So, opengl, dcom, what else do we need? :-) Write our own replacement. Try OpenGL first. We might have to clean-room reverse-engineer DCOM. IMO, the `core' operating system (besides the CD!) is the main installation disks and service packs. Anything else is what I call a `program'.

Re: Making builtin OLE32 work right
by Mike Hearn 19 Feb '05

19 Feb '05

Here is a brain dump of what I already know we need to fix for the CW supported apps: 1) InstallShield: RPC call re-entrancy 2) Lotus Notes: OLE drag/drop leaves an image of the window behind when it closes. Native does this functionality very differently to us. 3) VB apps: As Holly Bostick discovered to her cost, we can't load all OLEPicture resources correctly. Our OLEFont code also has misc bugs in, but we don't have any tests and code which uses these objects is rare so the full extent of the work here is an unknown 4) OLE Storage: IIRC misc things break in Office when this is pulled 5) Office embedding: We need marshallers for IOleObject for this, I think ... possibly a lot more. I do not know the details. 6) iTunes/iPod: Not fully investigated yet but I think we need to drop the typelib marshaller hack (this stands a good chance of breaking InstallShield for a short time as well) And one thing we probably don't care about: 7) Microsoft Transaction Server needs the typelib marshaller to generate RPC marshal-ops (format strings) instead of using custom marshalling like we do right now. But who cares about MTS while InstallShield and Office still aren't there? :) thanks -mike On Sat, 19 Feb 2005 10:58:27 +0900, Mike McCormack wrote: > Hi All, > > I'd like to compile a list of all applications that don't work correctly > without native ole32 (aka dcom95), then go through and try fix them. > > I think bugzilla is probably the right place to save the list, and that > alot of the information we're looking for is already in the appdb. > > How can we extract if easily?

modem
by Hartmut Haase 19 Feb '05

19 Feb '05

I'm not sure if this is the right address, but you can certainly forward it to the right person(s): I'm using an analog modem, and as it is not easy to select the appropriate cal-by-call provider, I tried to use web.de's SmartSurfer which works fine with windows. But wine gives me only the choice to select some 'WINE virtmodem' which is certainly not the right one. Yast tells me that my modem is device ppp0. What can I do? -- Viele Grüße, Hartmut Haase Hungerhilfe: http://www.thehungersite.com Das heutige Motto: The most exhausting thing in life is being insincere

The idea is to be able to attach multiple apps (versions) to the same bug. Right now we use "url" in Bugzilla to attach a bug to an app and that limits us to on app per bug. The feature you want is to be able to click on a link in a bug and see all the applications that that bug affects. I know exactly what I want it to do. I even have a bit rotted (almost) working version on my old machine. The problem I currently have is trying to keep up with the changes that Jon has been doing ( I don't work nearly as fast as him) so I have been waiting for the database to stablize a bit ... -- Tony Lambregts
