IIRC Greg Turner volunteer to do it however, also said I might take a while before getting around to do it. I, who did the stub, personally, haven't got much time to do it either. So don't hold you breath, unless you volunteer. Implementing it is not that hard I think especially since we got cabextract licensed under the LGPL for us. If not, install and use the native cabinet.dll instead.

As a Wine outsider, let me make a wild guess: To a first approximation, a nice way of thinking about it might be Write new DLLs using only published Microsoft APIs already implemented in other Wine DLLs. Ideally, new DLLs would work as replacements if compiled and run on a real Windows box. (although of course a whole lot of DLLs probably can't meet that strict definition.) - Dan

Janitorial Projects
by Dimitrie O. Paun 06 Dec '02

06 Dec '02

Folks, I have updated the Janitorial section: http://www.dssd.ca/wine/Wine-Fun.html#janitorial with the list of cross calls from 32->16, and W->A. There are currently 13 cross calls from 32->16 bit code, and 194 cross calls from Unicode to ASCII. Any takers? :) -- Dimi. P.S. If you do work on some of those, let me know so I can put your name there, and mark what's being worked on, do we can avoid duplicated effort.

how to switch between threads
by Rajesh Akkineni 06 Dec '02

06 Dec '02

Hi, I am debugging wine with MS Media Player. Some places the program is blocking with som 7 to 8 threads opened. They are all waiting for a some event(ConnectNamedPipe) But i think there should be another thread with will Create the file or NamedPipe. So How can i see where the other threads are when i set a break point in a perticular method. How dose debuggers handle MultiThreaded Applications? Can i Shit to different Thread to exmine where is it when the program Halted? Thanks Rajesh __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

You're right in theory but you're partly wrong in practice. Some time back I changed a shared library which had been used by ten or so developers for about eight years. I changed all possible unspecified length string copies and concatenates to versions with length limits. The programs using the library crashed less and displayed bad output less. Nobody noticed any speed change there might have been. We all had access to all of the source code involved and none of it was deliberately hostile to the library. The changes caught things the application programmers had missed in their testing and odd or corrupt data which ended up in the databases and made them less harmful. It was then also easier to follow up and fix "the program displayed xyz trash here" than it was to fix "my PC crashed" or "your program died". As programmers we all try to follow the limits and take care with buffer sizes and lengths and validation. We all fail and we all fail to catch every time we fail. That's just the nature of bugs and what we do. Buffer length issues are particularly hard to find and no realistic testing for a project the size of wine will catch them all. Wine also needs to remember that hostile Windows program developers may deliberately try to break programs under wine by passing invalid parameters. Even if wine doesn't check all of those, it shouldn't die when it happens. At least one company has an interest in breaking wine when running its programs and coding defensively is a prudent thing. Performance is unknown and won't be known until any possible shared function is implemented. Just announce it with the length parameter and do it with a define. Let the person who implements it decide whether to use strcat, strlcat or whatever in the first implementation, a function or inline or whatever. Six months or a year from now someone can try different implementations to see whether there is a speed difference. Then they can do something about selecting the most efficient. It's an issue, so deal with it, but there's no way to know today which will be the best implementation because it depends on the data and it is obvious that nobody knows the data well enough to be certain which will work best. If you don't like the strlcat implementeation, then you can try it with strcat and tell everyone how much faster it is when the l is ignored. Or not. Even if the l is eventually ignored in production, having it around offers the opportunity to turn it on with a compile option and/or to use it for assert sanity checking in a debug build. Finally, hi.:) Just started monitoring this list because I'm helping to get a Windows application (OzWin) working under wine.

Registering DLL's
by Jeff Smith 06 Dec '02

06 Dec '02

I was looking at entry C.5 of the 0.9 Todo list: "Make Wine's DLLs register themselves to avoid manual merging of the winedefault.reg [TODO]" Upon first glance I figured the approach is to (not necissarily in this order): add regsvr32.exe calls in the installation scripts, fill in the DllRegisterServer (and DllUnregisterServer) sections of the appropriate libraries, and remove those entries from winedefault.reg. About a dozen dll files have their names in winedefault.reg. So I checked the native versions of these files, and only half of them have a DllRegisterServer function. I did some further research and found that perhaps DllInstall was what I needed. Well, that only adds one library, and two have *both* functions. Does anyone have any better ideas on what the "Right Way" to tackle this item is? I am sure that adding external functions that do not exist in native versions is *not* the way. -- Jeff S _________________________________________________________________ Add photos to your e-mail with MSN 8.
