Using windows dlls in unix shared libraries
by Robert Jonsson 28 Dec '01

28 Dec '01

Hi all, I just subscribed to this list, I hope my questions aren't evidently answered elsewhere, I tried to do some homework browsing the docs and parts of the mailing list, but then again I'm no pro so I might have missed it. The background story: There is a plugin system for professional audio applications in Windows called VST. I suppose it does pretty much the same job as a multimedia codec. With the exception that they have internally generated GUIs! Perhaps a winamp plugin would be the closest match. There is a similar format in Linux called LADSPA (www.ladspa.org) Basically what I seek to do is try and wrap a VST plugin in a LADSPA plugin. The question: I don't know that much about Wine internals, but all the example applications I've looked at use the wine executable as boot loader. Does that mean that this is the only way to start a wine application? The way I'd like to use it is like this: Linuxhost (dlopen ladspaplug) - LADSPAplugin (LoadLibrary vstplugin) - VSTplugin A possible solution would be to startup the VSTplugin in another application and do IPC between the LADSPAplugin and the VSTplugin-proxyhost. Like this: Linuxhost (dlopen ladspaplug) - LADSPAplugin <----ipc----> winebased_VSThost (LoadLibrary vstplugin) - VSTplugin This does however seem akward... Is it possible to do it in an easier way? Btw, I know about the avifile project, don't know the history but it is based on wine right? However, to my knowledge avifile supports only a very limited amount of API calls, ie no graphics/window calls (perhaps except some trivial ones). Which would probably make it pretty hard to implement the above...

We *really* need a development model change !
by Andreas Mohr 26 Dec '01

26 Dec '01

Hi all, due to the number of regressions I found few days ago, it occurred to me that we really need an API test suite now. Thus I went ahead and implemented a test functionality for LoadModule16(). The result: 7 of the 21 tests that I implemented were FAILING !! That's ONE THIRD. And that for such a highly basic function as LoadModule16(). That's quite incredible. I guess we really should change our development model from trying tons of programs to *systematically* testing functions and Windows mechanisms now. If we can show everyone where stuff is failing, it might be a lot easier to attract new people. I attached a preview of the posting I intend to post on *tons* of Windows devel newsgroups ("Call For Volunteers"). That way we might actually get hold of hundreds of Windows developers helping us implement a complete test suite (complete tests of up to 12000 Windows functions). Not to mention the additional PR we might get out of this... If this works, then we'd need someone in charge of managing the assignment of specific windows functions to specific programmers. I won't do that (very limited time). Anyone from Codeweavers up to the task ? Or maybe someone non-developer and rather foreign to the Wine devel could do that task ? About the program: My goal was to get a program with very easy parsing interface: fields separated by colons, nothing fancy and difficult to implement, ... A .exe can be found at: http://home.nexgo.de/andi.mohr/download/wt_ldr16.exe Please comment on both my intended posting and the way I programmed the first version of the test suite (I'm not extremely happy with the current program; if you have any improvements, then get them here ASAP !). As 12000 Windows functions is an enormous number, I think we should really start doing this NOW instead of years later once Wine really needs this. Wine does not extremely need this yet, but we're getting pretty damn close to that already. Thanks ! -- Andreas Mohr Stauferstr. 6, D-71272 Renningen, Germany

I *completely* support this idea. Benefits of such test suite are enormous. Existing developers can contribute a lot by adding test snippets for the functions they create. Now they create such snippets anyway and throw them away. > I attached a preview of the posting I intend to post on *tons* of Windows > devel newsgroups ("Call For Volunteers").

Lets ask for help only after the suite structure is more/less defined and we'll be able to give people something to work on. Comments: - Don't want to reinvent the weel. Is there any existing test suite framework we can use? Sorry, I can't suggest any for C but I'm very impressed with JUnit in Java. It is even Ok if the framework is GPLed or LGPLed - I don't think any company will make buziness based on the test suite. - I /personally/ prefer CL interface only for such suite - it would be better if the suite print summary information and information about failed tests only - make the test suite more "visible" for existing developers. Ask them to run the test suite before submitting a patch? - I think the suite test will consist from a few separate applications because different tests may have different requirements to GUI configuration, processes, etc. We need a way to run all the applications in one batch. - define variable which indicates whether the suite runs under Wine. Such indicator can be used for Wine "white-box" testing. - it would be greate to have functionality to support output comparison? For some functionality it is easier to write tests to compare output instead of doing explicit checks (e.g. tests, involving a few processes). The output can be redirected to file and files compared. If we use files we need to store files for Wine and a few versions of Windows :-( - the suite applications size will be pretty big. Is it better to move it to separate CVS tree? - what about running the suite weekly (or daily) automatically and publishing the results to wine-devel? - most developers on this list have access to one version of Windows. Is it difficult to create "testing farm" with remote access to a few versions of windows? This would help developers to test their code on a few platforms. Existing environments in the companies, involved in the project can be used. - I remember long time ago there was a post on wine-devel about using Perl or Perl-like language for unit testing. What is current status of that project? Thanks, Andriy Palamarchuk __________________________________________________ Do You Yahoo!?

Cooperation between Odin & Wine
by Sander van Leeuwen 26 Dec '01

26 Dec '01

Hi, As some of you might remember I'm the lead developer of the Odin project. (project for OS/2 with the same goals as Wine). Odin is partly based on Wine code. The core dlls (gdi32, user32, kernel32) + some special dlls (winmm, directx, winsock) use some Wine code, but is basically incompatible with Wine for obvious reasons. Most of the remaining dlls are based entirely on Wine code. The last few years there has been little cooperation between both projects for several reasons. One of them is that we have far fewer active developers and cooperation sometimes proved to be difficult. Some source files of the two project had grown apart since changes were never merged back into Wine. Now, I'm trying to change this situation, but am wondering how to proceed. I can post bug fixes to this list, but it will be difficult for me to actually test these changes in Wine itself. (too time consuming) Posting diff files is not always possible due to the major differences between source files. Merging changes from Wine into our source tree is no problem. We can do that ourselves. However, it would be nice if compiler incompatibilites (we use IBM VisualAge C++, not GCC) could be resolved. There aren't many, but the IBM compiler is not always as flexible as GCC and of course doesn't understand any GCC extensions. It would be a big help if incompatible code could be changed. Switching compilers is not an option for us. I can post a (small) list of changes we had to make. The license of our project is not compatible with Wine, but the dlls that are largely based on Wine (such as comctl32, shell32, ole) are an exception to the project license. The sources of those dlls are released under the Wine license. In case there is ever interest in the other sources, then you can just ask me. I'd be happy to 'donate' them to Wine. For more information about Odin you can visit http://odin.netlabs.org (some information is outdated though). There you can find out where to download the sources (cvs). The next post from me will contains some patches for bugs in Wine that I've recently found. Sander

CVS server
by Dimitrie O. Paun 26 Dec '01

26 Dec '01

It looks like we're running an old version of CVS on the server, as it complains it does not understand #cvs up -C is it possible to upgrade it? That would be a good idea irrespective of the -C problem, as the new versions fixed quite a few (nasty) bugs. -- Dimi.

Re: Wine Tasklist (UNC)
by Mike McCormack 26 Dec '01

26 Dec '01

Hi Francois, I think the best way to handle UNC pathes is to do it properly; Wine should talk SMB/NBT directly to other machines on the network, not through Linux's VFS layer. This approach would give high level of flexability to Wine. We could: * support NetDDE and DCOM with a common code base * use Windows file permissions and security properly * support unicode share names properly * support named pipes, etc across the network * eliminate SMB<->VFS<->SMB problems eg. parsing /etc/fstab There's three options: 1) write our own SMB code (wineserver talks NetBIOS/SMB) i have a short snippet of code to resolve NetBIOS names in CreateFile, but that is only the beginning of the effort. 2) link with a LGPL'ed CIFS implementation. http://www.ubiqx.org/libcifs/ (very incomplete, but maybe possible later, may still have threading issues) 3) get Samba to provide us with a Unix domain socket to talk with. (SambaTNG looks like the best bet there.) i have experimented with linking Wine to samba's libsmbclient and use it to open files. That works (i have a test patch), has threading and licensing issues (it's GPL). This would be alot of work, but i think it's the only way to do it properly.

Patches for several bugs
by Sander van Leeuwen 26 Dec '01

26 Dec '01

Hi, Here are the bug fixes I promised. There are more, but I can post those at a later time. - controls\button.c CB_Paint, line 806 hBrush = SendMessageW( GetParent(hwnd), WM_CTLCOLORSTATIC, hDC, (LPARAM)hwnd ); if (!hBrush) /* did the app forget to call defwindowproc ? */ hBrush = DefWindowProcW( GetParent(hwnd), WM_CTLCOLORSTATIC, hDC, (LPARAM)hwnd ); -> (Auto)Check, (Auto)Radio & (Auto)3State buttons send WM_CTLCOLORSTATIC instead of WM_CTLCOLORBTN (verified in NT4) (fixes opening dialog buttons in Opera 6 (choose interface)) - dll\user32\text.c TEXT_GrayString, line 499 if(!hdc) { DeleteDC(memdc); return FALSE; } -> DC leak - COMCTL32: Comboex, rebar, tooltips, toolbar: NEVER delete the font object received by WM_SETFONT -> See attached diff files for comboex, rebar & toolbar. Our tooltips has too many differences for diff to produce usable output, but the changes are similar to the other three. - COMCTL32: Tooltips: wrong COMCTL32_Free calls -> 4 calls with wrong pointer: COMCTL32_Free(&lpttsi); should be COMCTL32_Free(lpttsi); - user32: frame tracking * - Only draw changed track frame instead of clearing the old one and * drawing the new one (less flickering) * - Send WM_MOVING when moving a window * - Send WM_SIZING only when sizing a window * - Fixed handling of rectangles changed by WM_SIZING/MOVING -> Can't easily produce diff file. Too many changes. (check src\user32\wintrack.cpp in our CVS tree) - USER32: groupbox redrawing fixes -> I am not 100% sure the same happens in Wine, but it looks like that. When an application changes the font or the text of a groupbox (smaller font or fewer characters), then the old text has to be erase properly or else you'll still see part of it. If I remember correctly, that could be seen in Opera 5.12 (property dialogs) -> Again, too many changes to produce a diff file. (check src\user32\button.cpp, BUTTON_SetText & BUTTON_SetFont) - USER32: static control -> our version supports more styles (SS_CENTERIMAGE, SS_REALSIZEIMAGE) and features (SS_ENHMETAFILE) (src\user32\static.cpp) Sander
