Is it as nontrivial as it appears
by Bill Medland March 28, 2003

March 28, 2003

I've now got to the stage where I have to look at whether it is possible for a linux process to call into windows dlls. (Don't bother telling me to use winelib to make the linux executable into a winelib one). I've never really thought too hard about it; it has always seemed to me that it ought to be quite trivial; just make sure you call the correct initialisaton functions and there you go. Indeed that has been my response on occasions on c.e.m.w and no-one had corrected me. I've just started looking at it and I get the distinct impression that due to the multiple processes and threads involved it may not be as trivial as I though. Anyone care to comment? -- Bill Medland ACCPAC International, Inc. medbi01(a)accpac.com Corporate: www.accpac.com Hosted Services: www.accpaconline.com

WineHQ: still TODO
by Dimitrie O. Paun March 28, 2003

March 28, 2003

Hi folks, Here is my personal TODO list for our very beautiful WineHQ site. Big Items --------- 1. Integrate Bugzilla into the site 2. Integrate AppDB into the site 3. Integrate the guids into the site Jer, silly question: Bugzilla and AppDB seem to already be written with the 'boxed' approach. I haven't looked at the code, but any fundamental reason we can't simply stick the main Bugzilla or AppDB main box into WineHQ? Medium Items ------------ 4. The Who's Who page is terribly out of date. Also, the organization with VIPs/Core/etc. sucks IMO. The page should include only the active developers, the rest should go into an Acknowledgements page. 5. Speaking of which, we're missing an Acknowledgements page. This should include significant contributors, significant corporate sponsors, funding sources. 6. The Download pages don't feel like. They should refer to the HowTo rather than duplicate the information. Also the Download/Sources is too skinny, needs more meat. 7. The HowTo needs improvements. There's a lot more stuff that we need to add to it. 8. We're missing a History page, that would put everything in context and a nice narative. Small Items ----------- 9. The Contributing page is too heavy, needs better integration with the new Fun Projects/Winelib/Janitorial pages. 10. The Sending Patches needs a bit more work. The .cvsrc link is wrong, maybe a bit more info on how to configure various email clients to not mangle patches, make it more clear that only uniffied diff is acceptable, show an example .cvsrc, how to email a patch (ChangeLog, one patch/per message, etc). Stuff we've been discussing for so long. Tony, I know you've been doing work in this area, maybe you can look into it? 11. TODO/Fun Projects/Janitorial/Winelib pages need constant updating from my site. I'll do that. 12. The Status/UI Status page still needs some work. Help wanted. 13. Get rid of the Miscellaneous section from Status/Core Status. 14. The Search box is too low, one needs to scroll to get to it, even in high resolutions. Any other requests? BTW, why aren't WineHQ CVS commits visible on wine-cvs anymore? -- Dimi.

I wonder if perhaps some older Sun JREs run better on Wine than hotspot does.

But the local DCOMTST case is only going to use named pipes or something. And I am actually using the native dlls.

No. If a function has a return code that indicates failure then you should test for that failure and not blithely continue as if everything was OK. They call FormatMessage, asking for FormatMessage to allocate the returned string. If nothing else, it could fail to allocate memory in which case it would be stupid to use the "returned pointer" which is just whatever happened to be on the stack at the time. And I noted it failing on Windows too; the printf or whatever simply stopped processing half-way along the format string. > > I am currently running native ole32 and native rpcrt4. > > Then you are really using Microsoft's DCOM implementation, and not wine's. > Which may not be a bad choice if you want it to "just work" Yes please > as much as > possible.

Good to know. Unfortunately it isn't my patience we are talking about. Do you know of any decent low level documentation that I could read that would explain why the native OLE doesn't even appear to be trying to hit the network? BTW, on the subject of specs, create_marshalled_proxy includes a reference to a figure at MSDN. Unfortunately the link is out of date. Any idea what it is a reference to? I had a quick look through the 1999 MSJ articles but didn't see anything obvious. Also, if I get bored and can find a few hours I was going to correct the arrangement of CoCreateInstance and CoCreateInstanceEx and tighten up the CoGetClassObject order of testing; does that conflict with anyone? -- Bill Medland ACCPAC International, Inc. medbi01(a)accpac.com Corporate: www.accpac.com Hosted Services: www.accpaconline.com
