The only thing the "macros" do is that it hides the way the parameters are marshalled. That is totally unintresting for almost all Wine developers. Like the Win16/Win32 thunking code you don't have to know how it works, you just call the appropriate functions. The same with the stdcall calling convention most API functions use. You add WINAPI before the function and you don't care how it works. It is the somebody else problem and you trust that they know what they are doing. So please explain what the use of FORWARD_* macros obfuscates for I really can't see it. AFAICS it is much better to use the FORWARD_ macros (especially with my hack to make them truely type safe). They are just a function like any other. Why look up how the parameters are marshalled when you can call a function FORWARD_* that not only does it, but does it in a type safe way. If you call the function with the wrong parameters you are very likely to get type errors. If you marshall the parameters in the wrong way it is almost 100% certain that the compiler will say nothing. Microsoft introduced the windowsx.h macros for a reason and while without inline functions the current implementation of the FORWARD_* macros was the best they could do, it was at least better than nothing since it at least handled the parameter marshalling even if it wasn't 100% type safe. Another things to think about: What is the difference between calling {Set,Get}WindowText functions and calling the FORWARD_WM_{GET,SET}TEXT macros? Answer: No difference at all except that you can easily do a PostMessage instead of a SendMessage if you wish. Of course I'm not suggesting that we should call the FORWARD_WM_{GET,SET}TEXT instead of {Set,Get}WindowText, but in most cases no appropriate functions exists and FORWARD_* macros will at least do the marshalling of parameters and if we implement my version of them also type safe. > Besides, the FORWARD_* macros are not really meant to be > used to send messages, they are meant to help receiving messages, so I > don't think we should abuse them that way. No, that is what the HANDLE_* macros are for. The FORWARD_* macros are for sending (or forwarding) messages. Speaking of which the HANDLE_* macros could find uses in COMCTL32 and other similar DLL:s to provide a type safe receiving of messages. I don't even think we will have to do as a proposed for the FORWARD_* to make them truely type safe.

I don't like it. I think windowsx.h should not be used at all in Wine; it only obfuscates things by making it harder to see what's really going on. Besides, the FORWARD_* macros are not really meant to be used to send messages, they are meant to help receiving messages, so I don't think we should abuse them that way. -- Alexandre Julliard julliard(a)winehq.com

True, but be aware of the macros often use a double type cast like (LPARAM)(HWND). I'm not sure this is really helpful, since I guess it will reveal but a few type error if any at all. Also note that the macros also takes care of MAKEWPARAM and MAKELPARAM stuff so it makes the code a little more readable. Anyway, never mind. We could be a little more clever than the macros permit that if we like. See below. > Note that for the specific case of WM_GET/SETTEXT, it would be much > better to use Get/SetWindowText which will do correct type checks. True. They was just an example. They are a few more with similar problems but they are few (less than 10 IIRC). I guess we can worry about them later. > But > for messages that don't have a corresponding function we have to do > the typecast. As the macros work now, yes. But we could extend the "macros" to be a little more clever than that. Take for example one of the more advanced macros #define FORWARD_WM_LBUTTONDOWN(hwnd, fDoubleClick, x, y, keyFlags, fn) \ (void)(fn)((hwnd), (fDoubleClick) ? WM_LBUTTONDBLCLK : WM_LBUTTONDOWN, (WPARAM)(UINT)(keyFlags), MAKELPARAM((x), (y))) We could quite easily write it like: #define _FORWARD_WM_LBUTTONDOWN(hwnd, fDoubleClick, x, y, keyFlags, fn) \ (void)(fn)((hwnd), (fDoubleClick) ? WM_LBUTTONDBLCLK : WM_LBUTTONDOWN, (WPARAM)(UINT)(keyFlags), MAKELPARAM((x), (y))) #if defined(__WINE__) && defined(__GNUC__) extern inline void _WINE_FORWARD_WM_LBUTTONDOWN(HWND hwnd, BOOL fDoubleClick, int x, int y, UINT keyFlags, WNDPROC *fn) { /* return */ _FORWARD_WM_LBUTTONDOWN(hwnd, fDoubleClick, x, y, keyFlags, *fn); } #define FORWARD_WM_LBUTTONDOWN(hwnd, fDoubleClick, x, y, keyFlags, fn) \ _WINE_FORWARD_WM_LBUTTONDOWN((hwnd), (fDoubleClick), (x), (y), (keyFlags), &(fn)) #else #define FORWARD_WM_LBUTTONDOWN(hwnd, fDoubleClick, x, y, keyFlags, fn) \ _FORWARD_WM_LBUTTONDOWN((hwnd), (fDoubleClick), (x), (y), (keyFlags), (fn)) #endif Or something like that. I'm not even sure the __WINE__ is needed. I not sure that any Winelib application could possibly misuse the macros in such a way that the result is not semantically the same (type warnings/errors excluded of course). Note that it is quite easy to write script that automatically does this to avoid subtle bugs especially since the correct (almost) prototype is already before each macro. Like in the case above: /* void Cls_OnLButtonDown(HWND hwnd, BOOL fDoubleClick, int x, int y, UINT keyFlags) */ This will give us all the advantages of the "macros" without any typecasts that could possibly hide a type error. What do you say? Note that we don't have to implement the solution above right now either. Using the macros as they are will not gain us very much (except possible a cleaner looking code), true. However when we implement the type safe "macros" as described above we will immediately find any and all type errors concerning such code. Anway fixing windowsx.h to look like above will not be very difficult either so there is no real reason to wait is it? PS. As hinted above this will also work with most (all?) Winelib applications that happends to use the windowsx.h macros and enable the finding of subtle type errors in such applications.

I think it's better to avoid that. Hiding the typecasts in the macros doesn't really make things cleaner IMO. This is a case where the API design forces us to use a typecast, so we might as well make it explicit. Note that for the specific case of WM_GET/SETTEXT, it would be much better to use Get/SetWindowText which will do correct type checks. But for messages that don't have a corresponding function we have to do the typecast. -- Alexandre Julliard julliard(a)winehq.com

RFC: Should we use the macros in windowsx.h to fix -DSTRICT warni ngs?
by Patrik Stridvall 10 Aug '01

10 Aug '01

This is not primarily a patch it is a RFC. I have experimented a bit with fixing the strict warnings. I have a few patch that I haven't submitted yet partly because I'm not 100% sure how all warnings should be fixed. Anyway, one large class of warnings is the ones cause by the window messaging functions. Like the one below: SendMessageW(lphc->hWndEdit, WM_SETTEXT, 0, (LPARAM)empty_stringW); This one unlike others this one does cause any warning with -DSTRICT because of the ugly cast, but the principle is the same. The only good way to fix this kind of problems that I can see is to use the FORWARD_WM_* macros in include/windowsx.h to write it like: FORWARD_WM_SETTEXT(lphc->hWndEdit, empty_stringW, SendMessageW); This works fine because the FORWARD_WM_SETTEXT macro look like this: #define FORWARD_WM_SETTEXT(hwnd, lpszText, fn) \ (void)(fn)((hwnd), WM_SETTEXT, 0L, (LPARAM)(LPCTSTR)(lpszText)) Actually I lied this special case will not work fine since FORWARD_WM_SETTEXT uses TCHAR and friends. But that is not so important for the general principle. See below. Anyway, in some meaning the macros only hides the casts, but can casts really be avoided? We must cast to {W,L}PARAM at some time mustn't we? And the macros in windowsx.h is not that bad they cast to the correct type before the cast to {W,L}PARAM. This might help to find some bugs. Perhaps rewriting to macros as inline functions might help to? So the question is: Should we use the FORWARD_WM_* macros to avoid typecasts (or rather avoid visable typecast) or should we not? If not how should we fix the problems? And if we decide to use them, is patches like the one below to include/windowsx.h that fixes the TCHAR and friend problem acceptable or should we solve such problems in another way? PS.

trouble with fonts (old, old problem)
by Mike McCormack 10 Aug '01

10 Aug '01

Hi All, i've got a problem with fonts in Netscape that's been around for a long time, while i've tried several times, unsuccessfully, to fix. When netscape 4.77 first loads, then loads an arbitary page, everything (text, buttons, comboboxes) is rendered incorrectly. If i go to another page, then hit the Back button, the page that was originally rendered incorrectly is now correct. All further renderings are correct for all pages. In my investigations (some time ago), i found that : * font enumeration functions returned different things on the first and second load of the same page. * i could correct the problem by changing the default ansi fixed font to helvetica i suspect that the wine loads extra X11 fonts between the first and second page viewings... but i don't know much about font handling in wine. i'll make some screen shots if anybody is interested. Any ideas?

Alexandre has made some changes in this area recently, but I don't believe they've changed that fundamental fact. So to do what you're proposing, you would first have to modify Wine's GDI code to support one of Microsoft's 32-bit graphics driver interfaces. (Different Microsoft 32-bit OSes have different driver interfaces, BTW.) You could then update x11drv to use this interface. As Patrik pointed out, this is really outside the scope of the Wine project, but I do think that it would be valuable. In addition to the reasons you give above, it would be helpful in improving both the Wine driver code and the Wine GDI code. -- ======================================================================== Ian Pilcher ian.pilcher(a)home.com ========================================================================

However to me it just seems like a silly hack to use the X11DRV_ functions for that or at least to use them directly. Anyway, so what you really want to be able to compile Windows source code to a Windows binary that instead of using normal USER/GDI instead uses Wine's version of USER/GDI that using the X11DRV displays the application's Window(s) on a X-Terminal? Hmm. Intresting idea. Well, yes that would be possible to do with Wine, at least in theory. There is a lot a practical problems to be resolved for that to work. Just getting the non-core parts (especially USER/GDI and X11DRV) to compile and link to a DLL with the Windows headers will be an effort by itself. Actually getting it to work will be even worse, The USER (and to a lesser part even GDI) seems, eventhough I guess they can be made not to, to use the Wine server for some things, with means that you will either have to fix that or emulate the Wine server on Windows. It is propably not that hard to emulate it, but quite a lot of work regardless. Then you have the issue of getting the Windows versions of COMCTL32 and COMDLG32 DLL:s and similar DLL:s using your special versions of USER32 and GDI32 and not the Windows ones. I'm not sure Windows can be made to support this at all. It depends on exactly how library loading work. Hmm, perhaps it would be possible to "hook" LoadLibrary somehow. Anyway, I'm sorry to say that it will currently not, with the state Wine is now, be possible to do that without an enormous effort. Despite this I'm happy to say that I think it will be possible some day. However not until past Wine 1.0 or perhaps not even past Wine 1.x. Nice idea though.

I think what I think you are proposing is currently entirely out of the scope of the Wine project. Wine is currently not designed for this. Compiling some of the non-core DLL:s like COMCTL32, COMDLG32 and others might be meaningful for test purposes, but the core stuff like the is simply not possible and it is not needed since Windows already has its own implementation of them that can used in the testing the non-core DLL:s. In short, what you are proposing is intresting but it has currently little to do with the Wine project. What you want to do is the write a Windows "graphic card" driver that display the result on an X-Terminal. While you certainly can (and are indeed legally allowed to do) use part of the x11drv to do this, I think most of the X11DRV is to high level to be useful. Sure someday when your "graphic card" driver works good we might consider redesigning Wine to use the Windows "graphic card" driver interface, but it will certainly not not be done before Wine 1.0 or even Wine 1.x. Perhaps Wine 2.0 might be a good point to merge such things with Wine, assuming of course that you or somebody else implements such a thing and releases it under an acceptable license (preferably the Wine license, the new one that is).

CoGetClassObject
by Daniel Walker 07 Aug '01

07 Aug '01

I was thinking of ways to get the CLSCTX_LOCAL_SERVER option working in wine. The only program that uses it , that I know of, is installshield v6 .. I pretty sure some other people are working on this, but I don't know that status. (Anyone care to update me?) There is another problem. It's with the TypeLib information in the IKernel.exe that comes with InstallShield v6. The TypeLib information is encoded somehow, any ideas? I was able to get around that problem because installshield also looks for type information in "ikernel.tlb" . So I was able to create a .tlb that worked. I also used the reaktivate typelib patch so the typelib info gets put into the registry. So the way I understand it is that when CoGetClassObject is called Wine is suppose to , in this case, execute IKernel.exe . Then IKernel.exe will CoRegisterClassObject on all needed objects .. One problem is that the registered class object list isn't shared between the two processes, so we would need to move that list into the wine server (Right?) .. Then we would also need to send an instance of the class object to the Wine server (Yeah??) .. Following that road seems to lead to some messy address translations for DLL's and whatever else.. Since we have complete control over how IKernel.exe is run, how would we get the two processes to share memory? Maybe have IKernel.exe execute in a thread? IKernel.exe doesn't do anything but register it's class objects .. Would it be possible to treat IKernel.exe as a DLL then run CoRegisterClassObject for it? Daniel Walker

Curiously (on the subject of InstallSheild) I have just successfully installed the latest (5.0.8) Lotus Notes client on a wine system (latest tarball) and the new Lotus installer is InstallSheild based. It ran perfectly EXCEPT that the program would not terminate. The Lotus installer takes over the whole screen, and that went away, but wine never returned to the command line. As far as I could see there were no messages about locks or anything. The only error message the installer came up with was a dialog saying "AddFolderIcon" failed. I had also understood that there was now a facility to add programs that would have installed themselves into the Windows startup menu into the KDE menu structure. I am running KDE 2.2 from CVS if it matters. But nothing appeared. Had I understood wrong, or do I need to try to do some debugging?

Allright, but the most important question remains: who will volunteer to reverse engineer these SLTG typelibs and make Wine able to read them, so I can concentrate on the actual COM marshaling stuff (which is pretty hard enough as it is), so we can finally get those @#&% InstallShields up?

Some questions about TB_REPLACEBITMAP
by Marco Bizzarri 03 Aug '01

03 Aug '01

Hi all. I'm trying to implement the TB_REPLACEBITMAP message in the comctrl32, and I would like to have some advice about the ImageList structure. The TB_REPLACEBITMAP provides (via the hInst, nID pair) the handle to the old bitmap and the handle to the new bitmap, as well as the number of button in the new bitmap. I think I could use the ImageList_Replace to actually replace the bitmaps. However, the ImageList_Replace function requires a number, which is the first bitmap to be replaced. How can I retrieve this information? For what I can see, once a bitmap has been added to the imagelist, no information about is is stored. I'm doing some tests, using a value (like 0) as the bitmap index, but this is of little help, of course. Any help will be appreciated. Bye Marco

I think you misunderstand my position; I'm not opposed to having a comment at the start of the function explaining the general goal and the non-obvious things going on. But if you need more than a couple of paragraphs to do this, then either there are too many non-obvious things going on in your function, or you are wasting space explaining the obvious. I do strongly think that the goal should be to write code that doesn't require documentation in order to be understood. Of course adding a small amount of comments is a good idea; but when you start having more lines of documentation than lines of code, something is very wrong IMO. But this is mainly a matter of personal taste, and except in extreme cases I'm not going to reject code because it has too much (or not enough) documentation. It may happen that some of your beloved horizontal lines get lost during the cvs commit though ;-) -- Alexandre Julliard julliard(a)winehq.com

I think that you cannot (and should not) attempt to force volunteer developers to add documentation to code. However, there are some few of us, who don't feel that the job is satisfactorily done until the documentation reflects important things that we've learned. I would say that I would rather have 100% of the effort a particular developer *wants* to put in, rather than only have his/her coding efforts. If I, like Bill, spend 24 hours ripping my hair out to learn some oddball things, I want a place to put those things. I want someone else (or an older version of me) to have a chance to not have to learn those things the hard way. Please don't misunderstand me. I agree that we shouldn't try to replicate MSDN. I'm not even sure we should provide minimal documentation like parameter lists and return values. Further, I agree that where it makes sense, the best place for comments is inline with the relevant code. However, I think that there should be a standard function header, with a standard place to put notes and comments in general about a function. I have been trained, and I suspect that many of us have been trained, to look at a function header for general tips and tricks before diving into the code. I know this is sacriledge to you, Alexandre, but there are some of us who like to quickly look at a function, rather than always reading the code to understand it completely. <in joke> Finally, I think all the code would be dramatically improved, in fact, I bet we'd be at Wine 1.0 by now, if there were nice big horizontal separator lines everywhere. </in joke>

I have to disagree here. Yes it would be nice to have a free Win API documentation, but it definitely doesn't belong inside the Wine source. First it would be a huge bloat in the source; and more importantly the Wine source doesn't define the Windows API, it is defined by Microsoft. > Of course developpers are very well-known for hating to document > stuff so it's going to be pretty hard to get proper documentation.

That should be done with comments inside the code itself. And in many cases it would actually be better to comment the places where the behavior is not right.

Documenting functions
by Bill Medland 01 Aug '01

01 Aug '01

Getting back to what we are and are not allowed to do.. Suppose I am looking at a low-level function that I believe is only 75%-complete (the most important 75% of course and no disrespect meant to those who have got it that far). One of the problems with it is it is not totally clear EXACTLY what the function should do in some of its more esoteric modes. To me the first task is to define what it should do and that should be part of the documentation of the function. The particular function currently does not have any true documentation within the code; the best documentation of what it does is the code itself, and the best documentation of what it should do is the MSDN description of the function. 1. Should the function be completely defined in its header in the source code (which will probably make the header twice as large as the function) or should the details be put somewhere else. 2. Are we walking into copyright danger if the Wine documentation of the function is clearly based on the MSDN documentation, even if we acknowledge that. 3. Are we interested in that level of documentation? Bill

This brings to mind the fact that three different kinds of "users": 1. Ordinary users 2. Wine/Winelib developers 3. Winelib application developers that need different kinds of tools installed.

broken misc/version.c (patch 1.43 -> 1.44) WIN95 value in version16

30 Jul '01

Two days ago a 16 bit application, which I use, started to complain about unknown windows version. After I rgressed to 1.43 of misc/version.c, everything was OK. I found the problem in the GetVersionInfo value that you changed at line 75 of the file. My windows 95 returns 0xC0000004 in WIN32 and 0x07005F03 in WIN16. You changed the 16bit value from 0x7005F03 to 0x7000304. Can you please check this? Do you have some docs? I think that we that we are both right; the value probably depends on longitude, altitude, and Windows language version. Mine iWindows 95 is Czech Edition, SR2. Regards Ladislav Sladecek

That is a correct conclusion. > I don't really see the point. The point is that when you are in some sub directory of a wine tree, you can just write winapi_check or make_filter and whatever and it will call the correct version of the tool. Instead of having to type, if you are in dlls/winsock. ../../tools/winapi_check Sure you can currently do make winapi_check or make filter and adding winapi_{extract,fixup} is trivial but giving arguments through make is a little awkward. That why I wrote a few script to fix this and now when I have a tool (make_filter) that could possibly enjoy a wider use I decided to make a formalized "install" for them. > If you want to install something it should > be a complete installation that works without external files (not that > I suggest doing that for winapi_check, at least not by default). A full install is largely meaningless since the winapi tools are made for work on a Wine source tree, so making them independant of such a tree is largely meaningless. Well they actually are indendent of the specific tree they where install from. They do not reference to it at all. They use the current directory to find the real winapi tools in that tree. They will work equally well with any tree (of a later date than your hopefull application of the patch that is). They are as they are by design, not by mistake, and complete installation of them is almost completly meaningless. Sure there might be future winapi tools worthy of a complete install, a future tool for automatical generation of .spec files from any Winelib application, that we talked about some time ago, comes to mind, but I'm not there quite yet. I have begun to implement simple typedef parsing but it doesn't work 100% yet. In short, please apply it, they facillitates using the winapi tools alot and might make more people actually use them. They don't hurt anything.

Wine Unreal and a strange old problem
by FT Rathore 29 Jul '01

29 Jul '01

Hi I have been using wine to play Unreal for a long time, but it would always crash in the start when I play as root or when I have my /dos filsystem mounted rw. It would always blow my mind, but I would fail to catch it. (been happenning for years too). I copied the whole Unreal tree to my ext2 filesystem and tried with different file permissions. I came to reallize that wine will allways crash if the file Unreal.log in Unreal/System is writeable. If I make that file read only, wine works flawlessly and I can do everything including save/load games. I tried to debug it, but the clues were very strange. There is only one message I see before the crash: err:seh:EXC_DefaultHandling Exception frame is not in stack limits => unable to dispatch exception. Besides that there is not much different between the good and the bad traces. I am attaching last 2000 lines of "-debugmsg +all" with this message. Someone might be able to get some sense from the trace. Anything else I sould do? FT

But, never mind, it doesn't matter. The point is somebody has souce code for a Windows application and wishes that it will run on Alpha. He or she doesn't care whether Win32 on 64-bit exists or not he wished to port his application with as little effort as possible. He or she doesn't care what magic Winelib does as long as it works and he has to change the source as little as possible. > If you want to > compile your apps as Win32, you need a 32-bit compiler. Sure thats an idea, but doing that is a little awkard, no 32-bit compiler currently exists for 64-bit platforms AFAIK. While this might work, at least in theory, if you only call the Win32 API, how do you suggest calls to 64-bit Unix libraries should be handled? > Then you use > the same compiler to build Wine as a Win32 library, and everything > works fine. If you use a 64-bit compiler, some types (including > handles) become 64-bit, and you have to deal with it. Since you refuse to make it easier for the porter, sure he or she will have to deal with it, that is pretty obvious isn't it? The question is what can we do to make it easier for the porters. We can almost always say "We don't care, its your problem", so that is not an argument by itself.

Well, that is a future problem. I don't know exactly how to handle it either, but as you pointed out earlier since we need to convert 32-bit pointers to 64-bit pointers we might as well convert 32-bit handlers to 64-bit handlers the same way. Of course that doesn't mean that being able to compile Winelib with handle as 32-bit integers won't help, but I really can't say whether or not right now.

RFC: Patch for making GrabPointer work
by Jukka Heinonen 29 Jul '01

29 Jul '01

After the following patch DXGrab works again. However, this patch has quite a few potential races, so I am not going to submit this to wine-patches. Storing old windows procedure in struct x11drv_win_data would remove the worst race, but unless window procedure update is atomic, it would not remove all races. I'm starting to think that QueueUserAPC used together with OpenThread (which does exist in Windows 2000/Me, but not yet in Wine) is the correct way to fix DXGrab.

OK, since you agree we should accept handles truncated to 32-bit, it still leaves the problem. Should API calls truncate the handles themselves ie take 32-bit integers as arguments or should they not ie take 64-bit pointers as arguments. There is no particular reason to not accept both and make the actual definition of handle be dependent on some define and leave the choice on whether they want warnings or not to the Winelib developers, not leave them without a choice. Actually we might also consider giving them the option to accept 64-bit integers. In short, the Winelib developers should decide what their application wants (warning wise), we shouldn't. > > So therefor I suggest that we should do the following > > TRACE("(%p)", (LPVOID) handle); > > You must be joking. No, I'm not. However reality forced me to change the solution somewhat. See below. > I said I didn't want any typecast, and here you > suggest to have one on every single debugging output. Well, we have (or should have) a debugstr_[aw]n? on every single string in the debugging output, because we have to.

Agreed, but there is no self value in having no exceptions on a rule. Remember no type cast is a means no a goal. Debugging output is hardly a critical piece of code so if we can gain something from it we should consider making an exception. But never mind, it turns out that we we needn't make a exception either. See below. > Not > to mention that your solution will probably still get a warning like > "converting integer to pointer of different size" on a 64-bit > platform. Ah, thats a good point. Practice often stand in the way of a good theory. :-( Unfurtunately I think you are right, it is more than probable that the compiler will generate such a warning, I if not now so sometime in the future. Casting to a 32-bit integer to 64-bit pointer is almost always bogus, so there is no reason for the compiler not give a warning epecially since you can do a double cast (32-bit integer to 64-bit integer to 64-bit pointer) if you really mean it. Fortunately the problem is solvable #ifdef __alpha__ #ifdef STRICT #define HANDLE2POINTER(handle) (handle) #else #define HANDLE2POINTER(handle) ((void *) (unsigned long) (handle)) #endif #ifdef STRICT #define HANDLE2POINTER(handle) (handle) #else #define HANDLE2POINTER(handle) ((void *) (handle)) #endif #endif TRACE("(%p)", HANDLE2POINTER(handle)); This solves your problem (at least for 32-bit developers) < The whole point of STRICT and pointer handles is to be able to use < compiler type checks, and this is only possible without typecasts. Francois problem < * Ignore gcc's warnings saying '%x format, pointer argument'.

Of course we might consider making it a debug output only construct instead Like s/HANDLE2POINTER/debugptr_handle/ and define it in debugtools.h. Non-debugging parts of Wine shouldn't need to use it either since as I said earlier just pass them long or must use an explict cast to a non-void pointer. Ah, wait a minute we will have "converting integer to pointer of different size" on 64-bit platforms for the actual cast to an object. Of course easily solved with a similar #ifdef __alpha__ #define HANDLE2OBJECT(type, handle) ((type *) (unsigned long) (handle)) #else #define HANDLE2OBJECT(type, handle) ((type *) (handle)) #endif but perhaps we should have the HANDLE2POINTER (debugptr_handle) in debugtools.h all the same, nobody else is intrested in a void pointer anyway. Of course, nothing forces us to define handles as the same both internally and externally. At least Alpha AFAIK will be binary compatible all the same, so we might not even need this. Oh well having to always using HANDLE2OBJECT is a small price to pay all the same and makes it possible for us to do adjustments on other 64-bit platforms if need be. And yes, I'm serious. My inital solutions wasn't so good, but thanks to your feedback I have managed to refine it to a much better solution, that I think actually works in reality. And yes, I still consider the 64-bit problem a real problem, you just tries to dismiss the problem by simply saying, that is the Winelib developers problem. Sure we could do that but, remember that Winelib is meant to help developers port application not make it more difficult by trying to enforce unnessary restriction on the code. Sure Win64 should use 64-bit pointers as handles that is without questions, but forcing it on Win32 on 64-bit is totally unnessary, especially since I now finally after your feedback managed to find a solution that solve all your stated problems (remember that no type casts is a means not a goal and actually there will be no type casts on 32-bit (-DSTRICT) either). But perhaps you can see any flaws in this refined solution as well?

An application that assumes that everything is 32-bit is broken, yes. I don't see why handles are any different than other types; if anything they should be less of a problem since they are supposed to be opaque, so their size should not matter for the application. Of course most handles will fit in 32-bit, so we will still support apps that do invalid casts and truncate the handles; but this doesn't mean it is correct behavior, or that apps that do this should be able to compile without warnings. > So therefor I suggest that we should do the following > TRACE("(%p)", (LPVOID) handle); You must be joking.

That is an internal Wine/Winelib problem and shouldn't need to concern porters of Winelib applications. > So no, there is absolutely no reason > to force handles to be 32 bits. Handles are some sort of values as for as whether they are integers or pointers any Winelib application that cares are IMHO broken. I guess you agree on that point. However your suggestion that any Winelib application that cares whether they are 32-bit or 64-bit are broken is a far too strict IMHO and I see no reason to require porters to fix such things. Note that it might no be so easy to fix it either. Perhaps the application uses some external lib that provides storage of some user defined 32-bit data and use it to store the handles. Now it will suddenly not work anymore, and fixing it is not trival. Hint you are on a 64-bit platform that requires 64-bit pointers and you have 32-bit storage. The obvious solution an index of an array might not always work so well because of memory management requirements and beside the maintainer of the project might not accept a special patch for the 64-bit version. Anyway, never mind. See below instead. Sure pointer face in some meaning the same problems, but that sort of problems is more obvious and there is no reason to add more to the burden. > > The real reason that we should support compiling Wine with -DSTRICT > > is not because handles becomes pointers but because callbacks gets > > the correct prototype. > > No, it's because handles become pointers; you cannot do the -DSTRICT > typechecking with integers anyway. True, you can't do typechecking with integers but since Wine is primarily compiled 32-bit platform that will use 32-bit pointers, we will get the benefit of typechecking at the platform, which happends the only one Wine currently works on. Sure future developers on 64-bit will not find the errors then they compile, but everybody else compiling for a 32-bit platform will, so I don't see the problem. > Callbacks are a very minor issue; > the real point is to fix all incorrect handle manipulations, like > implicit 16-bit handle conversions or arithmetic on handle values. The ones of the above that can be found automatically will be fixed by the 32-bit developers. So the actual problem is what? Anyway, this discusion is getting a little carried away (mostly my fault). While I do not currenly agree that we really should use 64-bit handles on 64-bit platforms, your objections have made me think some more and made me come to the following conclusions. In order to not "close the door to the future" whether this is Win32 on 64-bit or Win64, the Wine code shouldn't internally not care (give errors or warnings or be semantically wrong) whether the header files: 1. Defines handles as integers or pointers 2. Defines handles as 32-bit or 64-bit (regardless of whether we have 32-bit or 64-bit pointers) This is not so a for the normal (non-debugging) code. OK, we might have to force memory allocation of objects for the lower 32-bit of memory if we have 64-bit pointers but that is probably not so large problem. After all the Winelib application itself can allocate memory on the full 64-bit memory range and Winelib itself are not likely to need more that 4Gb memory for objects. However, I see no really good solution for the debug output. Neither mine nor your previously suggested solution have the above properties. However the solution below have, I think TRACE("(%p)", (LPVOID) handle); eventhough it might display unnessary information on 64-bit platforms, but perhaps we should worry about that in the future, if it indeed is a problem at all. After all it is only a few more bytes in the debug output. So therefor I suggest that we should do the following TRACE("(%p)", (LPVOID) handle); It will fix the problem that Francois speaks of in bug report #90. < * Ignore gcc's warnings saying '%x format, pointer argument'. Fixing the format < at this stage would only introduce tons of warnings for the developpers not < participating in the switch (i.e. compiling with STRICT off). It will allow us to fix the debug output one by one (or at least seperately per type) since it will allow us compile without related warnings even without -DSTRICT as well as to prepare us for a possible future where handles might be 32-bit integers on 64-bit.

Oh sure, but the point is that if code, that are semanticly correct, cares whether you are strict or relax the type, the code it wrong. Perhaps I was I little unclear on that point. Being strict obviously makes it easier to find semantic errors, but that was not the point at all. > About 64bits Windows I don't know yet how we are going to do that. > But you have to check exactly what Windows 64bit does, not just > extrapolate from the way Unix 64bit does things.

The reason I did that was that they can't be fixed as long as HANDLE/HGLOBAL is the wrong types. When they become the right types the warnings will automatically disappear and we can do s/DECLARE_OLD_HANDLE/DECLARE_HANDLE/.

Since we can't fix before that why show them at all?

If you have to add typecasts something is wrong. No typecasts where the handle is used in conjuction with other handles, certainly not, no argument there. The code some expect all handles to be the of same type. However for the debugging output I disagree. I orginally thought as Francois (and you it seems) that handles are pointers and should be treated as such. But then I realized that when we implement Win32 on 64-bit platforms we can't have handles as pointers even internally if we wan't to support x86 emulation and even exposing a 64-bit handle to Winelib application can only cause trouble since they might store it is a 32-bit memory location. Sure we will probably be able to handle 64-bit pointers truncated to 32-bit by storing all objects in the lower 32-bit part of memory, but fear it might cause trouble all the same. Beside doing TRACE("(%p)", handle) on 64-bit platforms will needlessly display the always the same presumably zero upper 32-bit part of the handle. That why I decided to should use TRACE("(0x%08lx)", (DWORD) handle) instead to avoid such issues. In short, the code should IMHO support both 32-bit pointers as well and 32-bit integers as handles presuming of course that all handles use the same. The real reason that we should support compiling Wine with -DSTRICT is not because handles becomes pointers but because callbacks gets the correct prototype. I case not you haven't realized the obvious, it doesn't matter if the handles are 32-bit integer or 32-bit pointers as long as all handles are the same. The code either 1. Just pass them around as the same type of handles of other types of handles (HANDLE/HGLOBAL). 2. Tries to access the underlying object, in such case a void pointer will not do use any good, we must use a cast either after calls to functions like GlobalLock or alone.

Handles are pointers in the Windows API, and they should be pointers inside of Wine. On a 64-bit platforms pointers will be 64-bit, and so will handles. If you want to run 32-bit code on such a platform you need a conversion for pointers anyway, so you might as well use the same conversion for handles. Not to mention that some handles are actually pointers (like HMODULE). So no, there is absolutely no reason to force handles to be 32 bits. > Beside doing TRACE("(%p)", handle) on 64-bit platforms will needlessly > display the always the same presumably zero upper 32-bit part > of the handle.

No, it's because handles become pointers; you cannot do the -DSTRICT typechecking with integers anyway.

That's precisely the plan, and it is just the opposite of what you are doing with your patch (you are turning DECLARE_HANDLE back into DECLARE_OLD_HANDLE). Yes you get a number of warnings if you turn -DSTRICT on, most of them should disappear once the conversion is complete; fixing them before that is a waste of time. This is the reason why -DSTRICT is not the default yet. Read bug report #90, Francois explains everything there. And don't forget the number one rule of the -DSTRICT conversion is: *no* *typecasts*. If you have to add typecasts something is wrong. -- Alexandre Julliard julliard(a)winehq.com

Alexandre Julliard: > I think GetClipBox is correct, the problem is > that the WM_ERASEBKGND > handler should not be using it, but > GetClientRect. You can try this: Hello Alexandre, thank you for your reccomendation. Unfortunately the DefWindowProc improvement does not help, because the default handler newer gets called in my app. The application (Progress _prowin.exe version 7) uses custom dialog boxes (forms) and also custom controls. The controls handle WM_ERASEBKGND themeselves. I have no access to the sources. What I know about GetClipRect, I know from the trace. I agree that your method (GetClientRect in the handler) is much better, but I cannot use it. I also agree that Windows should return the parent area in GetClipBox as Wine does. Unfortunalelly, the Windows do not do that while the _prowin.exe depends on it. I enclose a simple C example which I hacked to demonstrate this. The example displays two red children in a white parent. The value returned by GetClipBox is wsprintf-ed. If you run the binary in the Windows, you will see two properly sized red rectangles on a white background. If you run the same binary in Wine, you will see only one large red child but no white parent background. If either the CS_PARENTDC or WS_CLIPSIBLINGS gets removed from my example, both Windows and Wine give identical results. Regards Ladislav Sladecek

That's where the work is. Yes. I've noticed that and I have fixed a few of them as well. However I'm not optimistic on fixing them all on the short term. The problem is not the number of them, the problem is that some of the warnings like the Global* can't be fixing in the .c files. It involves changing the .h files and that generated even more warnings. :-( I will investigate furher, but as I said, I'm not optimistic.

Hmm, I was going to try something like that, however, I had problems with that method simply b/c of the load order between the dlls. ChangeDisplaySettings is implemented in user32.dll which loads BEFORE x11drv. This makes it impossible to initalize the function with the user32.dll. However, with DDraw, the x11drv.dll is loaded before the ddraw.dll! The only way I saw to exchange info was to initialize the function with a call from x11drv.dll. If you can suggest an alternative that takes load order into account I will likely use it. > Moreover, there are already some DDraw-related mode change functions (in > dlls/x11drv/xvidmode.c).

Any use for glyph bounding boxes in printer driver?
by Ian Pilcher 27 Jul '01

27 Jul '01

Currently, the Wine PostScript driver stores the bounding box (xMin, yMin, xMax, yMax) for every glyph in every font. This information is not currently used, and I'd like to get rid of it. (Note: this is distinct from the advance width of each glyph, which is certainly required.) >From what I can tell, there is no API that a Win32 application or the Windows GDI can use to get this information from a printer driver. Since I'm not that familiar with either, however, I figure I should try to confirm that this is indeed the case. So, does anyone know of any API that an application or the GDI can use to get the dimensions of an individual glyph from a "real" Windows printer driver? (I have verified that calling the GetTextExtentPoint functions with a one-character string returns the height of the font, not the height of the glyph. For example, it returns the same height for 'A' and '_'.)

Try and run it it is self describing. :-) Since Alexandre didn't apply the Makefile patch, running it is a little awkwark. Will fix that it later versions though. Try do: cd wine ./tools/winapi/make_filter make You can also give it parameters like ./tools/winapi/make_filter make clean Warning "make clean" doesn't look that good currently. PS. It filters the make messages and only display important messages. It might not always work 100% though, but I will fix problems as I find them. I wrote it many months ago and have run it from time to time since, so most issues have been fixed. The reason I wrote it was that I was irritated that important messages scrolled of screen. > If it's nice isn't it worth advertising to the Wine > developper community? I had intended to do that if but since I was unsure that Alexandre would apply my Makefile patch I decided to wait until it could present a better "user interface". But by all means test it.

It is not in my Microsoft Visual C++ 6.0 header, but perhaps you have a newer version?

Because it would be incompatible (warning wise) with Winelib applications compile with -DSTRICT since Windows doesn't provide a special -DSTRICT version of HOOKPROC.

Well, make_filter actually calls make already. :-) Seriously, one reason that I added it to the Makefiles in the first place is that make_filter doesn't know what version of make to use. Sure it is called make on almost all systems and gmake (GNU Make) on most of rest, but since the user knows and calls "make", $(MAKE) contains the correct "make". Oh well, I guess just calling make will work on most platforms, it will on all platforms that I current use. The Wine Makefile is supposed to be portable so I guess it will have to do.

How do I stop clipping?

I don't like submitting incomplete code but I may have little choice unless someone can point me in the correct direction here.

I am working on correcting the LISTVIEW_DrawLargeItem function, especially when the item text is large. I have already got most of the way. However the problem is this. When a user selects a large icon the text should be written completely (by calling DrawText with DT_NOCLIP). It is doing so; I can prove it by resizing the window and I will see the full text being displayed for a selected item. However when drawing it at the moment of selecting it, the text is being clipped to the usual two and a bit rows.

Wine Winex Half-life/Nox and alsa
by FT Rathore 25 Jul '01

25 Jul '01

Hi I tried Jul 23 cvs of wine and winex and tried with Nox and Half Life. Both wine and winex work fine with the stock kernel sound drivers (es1371) but they do not work well with alsa with oss emulation. The sound gets played extremely fast in Half-Life like someone hit the fast-forward button. It is strange because the timing on the alsa oss-emulation (and commercial oss drivers) is better than the stock kernel drivers. Winex does a lot of improvement in Half-Life and it is fully playable (the splash, the menu and everything). Nox works near perfect with wine but it does not work at all with winex. FT

Microsoft source code releases - a danger to Wine?
by Ian Pilcher 24 Jul '01

24 Jul '01

According to Slashdot, Microsoft has released the Windows CE source code under one of their "shared source" licenses. Needless to say, it would be an *extremely* bad idea for anyone associated with the Wine project to look at it. This leads me to wonder if anyone's ever thought of taking steps to protect Wine from "contamination" by Microsoft IP (legally, not tech- nically :-). As the number of programmers who have been exposed to MS source code grows the chances of this happening will increase. I believe that the FSF uses some type of form/statement before they will accept code, and it seems like the nature of this project would make it particularly beneficial. -- ======================================================================== Ian Pilcher ian.pilcher(a)home.com ========================================================================

[PROBLEM REPORT] Edit control line scrolling
by Gerard Patel 23 Jul '01

23 Jul '01

With programs using a multiline edit control, such as Notepad (I'm using Win3.11 version) or Eudora Light 1.5 with mails from the 'In' mailbox (this is a 32 bits application), scrolling down the edit buffer line by line mostly does not work. In fact, it works only if the edit buffer size is an exact multiple of the line height. In all other cases, the format rectangle is smaller than the client size, and when the edit control tries to redraw the last line, the update rectangle is wrong : only the lower part of the line is drawn. I think that this problem can be traced to the replacement of code in ScrollWindowEx by the call to ScrollDC. What is happening is that the client rectangle is scrolled, but the client rectangle is bigger than the formatting rectangle by a few pixels; these pixels are missing in the update region. In Wine previous version, the client rectangle was first ANDed with the so-called 'visible region' (hvisRgn), so the result was not bigger than the format rectangle before being scrolled, then diff-ed with it. The following patch works around this problem. I don't have time to investigate further as I am taking one week of holidays :-) but if someone is interested in the edit control....

Why is this wrong?
by Bill Medland 23 Jul '01

23 Jul '01

The code of "perfect_graphics" (attached) gives my system problems. The visible aspect of the problem is that the text in our application's listview doesn't get drawn properly. By experimentation I have narrowed it down to when perfect_graphics was edited. I observe that our application works correctly under the two following cases: 1. When the body of the function is removed and the value is hard-coded to true 2. When the "inline" is removed (which is the fix I am proposing and will submit in a moment) Since I do not like working without understanding I would like to know: Is there something wrong with the use of "inline" in this context? Or is there clearly something wrong with my build environment? Or is everyone else as confused by it as me?

Still problems with snoop
by Uwe Bonnes 23 Jul '01

23 Jul '01

Hallo, some days ago I reported early crashes when running with the snoop debug option. E.g. vc98 msedv.exe is a good example. Running with "+snoop" crashes early. Running with "-snoop=devshl" lets the program succeed much further. Running without snoop gets even substancial further. So I think there must be something wrong with snoop. I tried to look hard at relay32/snoop.c, but didn't see anything fishy. So perhaps somebody else has some idea what's going wrong.

IIRC the doctrine of "inevitable disclosure" it on a little shaky ground as it is eventhough some Judges have use it so far, it is NOT 100% established doctrine. As far as the Wine project is concerned, you will have to stretch the doctrine pretty far since the Wine project can't possibly know what a patch submittor has done before unless he tells us himself. > This is what I'm really worried about.

The burden of proof is on Microsoft. Of course it is a civil cases and the proof need only be on preponderence of evidence but it still their burden primarily. > Worse yet: If we coincidentally use similar code to theirs, how can we > prove we haven't looked at their code? If I were paranoid, I'd say the > single purpose of releasing the source was to get wine in trouble. First of all: We know who submitted a patch since that information is in the CVS log, so unless they can prove that Alexandre should have realized the person submitting the patch, submitted code not copyrighted by that person, the burden fall on that person and that person alone. If that person can't be identified through the e-mail adress to bad for Microsoft. If he can they will have to drag him to court, not the Wine project. Sure Microsoft probably can ask the Wine remove the offending code and sue us if we don't, but since we in fact also are a victim of the submitters misrepresentation I think any reasonable judge would: 1. Require that Microsoft prove that the code is theirs. This might be a little difficult without providing the actual code to the Wine project and requiring any developer of the Wine project to taint him self by signing a NDA with Microsoft would probably not required by the court. So the reasonable cause of action would for Microsoft to release the code without a license that could taint us or pay for an independent 3rd party to review and establish this. 2. Require that Microsoft provide a patch to remove the offending code from the current CVS. Note that we also are a victim so requiring more would probably be considered unreasonable. Why should we pay for (in money or effort) somebody elses crime or legal liabillity against Microsoft. All in all I think the Judge would be rather annoyed that Microsoft didn't try to solve this problem without him. In short, while IANAL, if Microsoft (or somebody) feels that some code in the CVS is copyrighted by them we should simple require that. 1. Prove it to us, without any risk of taint, or to some independent 3rd party at their expense. 2. Provide a patch against the current CVS that removes the offending code preferable made by the same 3rd party as above at their expense. 3. Require that the 3rd party sign a statement under perjury that the patch removes the offending code and only the offending code. Remember we are also a victim under such an event and requiring more would probably not be look on favourable by the courts.

Wine doesn't seem to like TrueType fonts.
by David Hagood 21 Jul '01

21 Jul '01

Has anybody else seen this behavior: I have a directory of TrueType fonts that I can point xfs to. When I have that directory in the fontlist, wine ALWAYS regenerates the font cache on every start (thus slowing Wine down immensely). Remove the TrueType directory from the font table, and all is well: Wine will regenerate the font cache once, and then use the font cache from there on.

Marshaling
by Daniel Walker 21 Jul '01

21 Jul '01

From what I've read when someone creates a custom interface for COM, an IDL file is generated, then the MIDL compiler uses the IDL file to create proxy and stub code that works with the standard COM RPC functionality.. So under some (most) circumstances wine's COM implementation would only have to facilitate the sending and recieving of the marshaled data .. Not to minimize the work involved .. The standard marshaling would have to do all the generic COM interfaces like IUnknown, IStorage, IStream (I think). Even though full implementations of those would be available . But most components would have custom interfaces so they would also have their own marshaling code .. If I'm 100% correct then , I guess, there wouldn't be a need for the type information. Yet it exists .. Unless the type info is used for something other than marshaling. Daniel Walker

Exactly; but note that in most cases the prototype is not even needed at all.

Well we could actually make them truely static with a little trickery and a corrensponding change of winebuild. Idea: #define DECLARE_ENTRY_POINT16(module, function) \ void *module##_p##function = (void *) &function /* After the includes */ static void Foo(void *, int); DECLARE_ENTRY_POINT16(BAR, Foo); /* ... */ static void Foo(void *, int) { /* ... */ } It is probably not worth the trouble though. > They > cannot be because of the spec file reference, but ideally no code > should ever call a 16-bit API, it should use the corresponding 32-bit > API.

You want all 16-bit exported function prototypes moved from the .h files to the implementing .c file in all cases that is is possible (ie Wine compiles without errors or warnings)? Do you also want the types and structures moved as well? That will often not be possible, but do you want it despite this in the cases where it is possible?

Is this case in don't think it matters so much though, your orginal solution is fine, in fact is the standard solution in C to the problem you have AFAIK. My suggestion is really just brainstorming to give you hopefully a different perspective of the issue. Also note that your solution is not possible with languages that don't have pointer aritmetics that C, fortunately or unluckily depending on how you see it, have.

All 16-bit API functions must be treated as if they were static. They cannot be because of the spec file reference, but ideally no code should ever call a 16-bit API, it should use the corresponding 32-bit API.

Ah. You are right, I orginally meant to add it in a different file (wine/obj_base16.h perhaps) but I didn't think it would matter since other 16 bit interface like IStream16 and IStorage16 is in wine/obj_*.h already. Perhaps they should be move out as well? If so to where? wine/obj_*16.h or perhaps the DLLs directories if possible? > Also please avoid adding more 16-bit headers in include/wine, there > are already too many of them. Well that was the idea at first but at least of the new ones are was needed in more that one directory some I ended up adding all of them there. But sure I can move the ones that are not use in more of one directory to that directory, I'm just a little worried that since the wine/*16.h header are 16-bit "mirrors" of the corresponding 32-bit files that functions from other DLLs happends to end up there as well. Microsoft seems have mixed headers and DLLs without much thought especially as far as OLE is concerned. Sure we can have several .h files with the same name in different DLL directories as far as functions are concerned since 16-bit functions shouldn't call across different DLLs anyway, but duplicating types and such are not a very good idea. But sure I can examine the files more carefully and see if it is possible and of course we can add it to a DLL directory first and then move it to include/wine if is because nessary in the future. > These headers (when they are really > necessary) belong in their respective dll directory. And BTW your new > lzexpand16.h is an example of a header file that is *not* necessary. Nessary for compiling Wine no, clearly not since it already compiles. However IMO all exported functions whether they are 16-bit or 32-bit and whether they are actually uses by other files or not should have declarations in some header file. For 32-bit it must obviously be so because of Winelib. The undocumented functions is of course not strictly nessary but I see not reason not to have them as a Wine extension that can be ported to Windows eventually in order to have the same source on both Unix and Windows. For 16-bit is seems that you disagree. Well, the advantages that I can think of for doing it for 16-bit as well is the following. 1. It makes it much easier for developer to add calls across files between 16-bit functions or move functions between files if the infrastructure is alreay in place. 2. It makes it possible to see related 16-bit functions together in a .h file instead of having to search the .c files. 3. It makes it possible go through each 16-bit .h file compare it with Windows and add the missing functions in the .h files and when somebody in the future runs winapi_check (or whatever) it is possible to present a list of what is not yet implemented. Sure the .spec contains that information as well in some meaning but it misses which functions that are actually listed in the 16-bit header files and thus likely to actually be used by real applications. 4. Since some of the 16-bit exported functions must be declared in some .h since it is used in some of file than it was declared, it is be much easier to require all 16-bit export function to be declared since it is difficult to tell which that are (or will be) really needed. 5. There is nothing unreasonable to require every non-static function let alone functions that are exported by either Win16 or Win32 to have a declaration in some .h files. Indeed tools like lint (at least on Solaris) have flags to check for this. In short trying to only add the 16-bit functions that are stricly nessary to .h files is more trouble than it is worth, especially compare to the advantages that having all of them .h files. In addition (as I hinted in 5.) requiring all non-static functions to have a .h file declaration is good policy for any application including Wine. Hint, if a function isn't static somebody else should use it otherwise some else is wrong, ie it really should be static after all. But OK. You think that there are too many 16-bit files in include/wine. No problem. I will try to avoid it if at all possible.

Not really, but as an alternative solution you could has a structure instead of an array like: typedef struct { GLYPHNAME A; GLYPHNAME AE; GLYPHNAME AEacute; GLYPHNAME AEsmall; /* ... */ } GLYPHNAMES; Perhaps this is better since it doesn't use the preprocessor. However I'm not sure if all C compilers supports 1258 structure members. Another possible problem is alignment on some platforms if you must be able for iterate over it and use it as and array. Of course you can simply have a seperate array of pointers like: GLYPHNAMES glyphnames = { /* ... */ }; GLYPHNAME *pGlyphnames[] = { &glyphnames.A; &glyphnames.AE; &glyphnames.AEacute; &glyphnames.AEsmall; /* ... */ };

Lots of #defines OK?
by Ian Pilcher 19 Jul '01

19 Jul '01

I'm giving some thought to cleaning up the data structures used by the PostScript driver. Any significant change here will require that the glyph list and font data be regenerated. This is not particularly difficult, but it would be easier if I could remove the dependency of the font data on the glyph name array. Each glyph's metrics include a pointer to its name, and all of the built-in glyph names are in a single array named PSDRV_AGLGlyphNames (in dlls/wineps/data/agl.c). So the metrics for a glyph look like this: { 33, 0x0021, 600, PSDRV_AGLGlyphNames + 907, { 236, -15, 364, 572 }, NULL /* exclam */ } I would like to get rid of the "hardcoded" offset into the glyph name array and replace it with a macro ('GN_exclam', for example). Each font data file could then simply include a header that gets regenerated when- ever the glyphlist is changed -- eliminating the current requirement to regenerate all the font data. Anyone see any problems with this? (There are currently 1258 built-in glyph names.)

Problem with 'GetPrivateProfileString'
by Lionel Ulmer 18 Jul '01

18 Jul '01

Hi all, I have an installer crashing in 'GetPrivateProfileString' because of an NULL section pointer : 3 0x40076161 (GetPrivateProfileStringA+0x31(section=0x0, entry=0x40391efc, def_val=0x4039a394, buffer=0x403b0410, len=0x3e7, filename=0x4039a4e8) [profile.c:1232] in libntdll.so) (ebp=40586748) When looking at the code, there is the following comment (and code) : /* * undoc_feature means: * return section names string list if both section and entry are NULL. */ (...) if ((undoc_feature) && (section == NULL) && (entry == NULL)) /* undocumented; both section and entry are NULL */ But if I look at the entry for 'GetPrivateProfileString' in the MSDN, I get this : pAppName [in] Pointer to a null-terminated string that specifies the name of the section containing the key name. If this parameter is NULL, the GetPrivateProfileString function copies all section names in the file to the supplied buffer. lpKeyName [in] Pointer to the null-terminated string specifying the name of the key whose associated string is to be retrieved. If this parameter is NULL, all key names in the section specified by the lpAppName parameter are copied to the buffer specified by the lpReturnedString parameter. This is not in sync. with what Wine does.... It seems that only pAppName needs to be NULL to return a section name list. And there is another behaviour not done by Wine yet : copy all the keys of a section to the output buffer. So who is the author of this 'undocumented' feature in the Wine code ? Do you all agree that I should code it according to the (now) documented feature ? Lionel -- Lionel Ulmer - http://www.bbrox.org/

This is more a limitation of the malloc implementation than an actual bug. malloc uses brk() to allocate memory, but brk() cannot grow past an mmapped area, so malloc fails. With a standard Linux app shared libraries are mapped high in memory (usually from 0x40000000) so the malloc limit is about 1Gb; but if stuff is mapped lower, malloc capacity is reduced. The reason it works for mallocs larger than 128Kb is that glibc uses anonymous mmaps to reserve space for these instead of brk(). All in all, it's probably one more good reason for avoiding malloc in Wine. -- Alexandre Julliard julliard(a)winehq.com

Announcement : SynCE project
by Ludovic LANGE 18 Jul '01

18 Jul '01

Hello, First of all sorry for the intrusion, but I think this may be of interest for some of you. SynCE project's ambitious goal is to provide a mean of synchronising handhelds devices with a (desktop) computer. By handheld, we mean any portable / embedded / PDA.... device, that needs to synchronize its data with a less mobile computer. (An exemple would be any PDA/PocketPC running Windows CE, or any PDA running Linux, etc...) The first step of this project is to provide a full (client & server) implementation of Microsoft's RAPI protocol, which is the low-level protocol used in ActiveSync synchronisation. This will allow, when completed : - a Windows CE device to communicate with any (non-Microsoft) computer, - A Linux device to communicate with a Microsoft computer and benefits from the existing tools, - etc, etc... The second step will be to provide a set of tools to synchronize data with 'standard' open or closed source application : Mozilla, KMail, etc.... Right now, the project is in its early, early stages ( we don't even have an alpha release ! ), but yet there are some bits that allow an implementation of the client part of the RAPI protocol, to query informations (registry, filesystem, databases,...) from a WindowsCE device. One tool (DBBackup) allows a full dump of the databases of the device. I won't interfere more with the list, and I invite all people interested to have a look on the project page ( http://www.sourceforge.net/projetcs/synce & http://synce.sourceforge.net ) and to subscribe to the mailing-list. We currently are looking for developper, and for testers having mobile devices still under Windows CE (PDA, PocketPC, etc...) and an unix-like desktop environment. Best regards, Ludovic LANGE

glibc bug mmap/malloc
by Andreas Mohr 17 Jul '01

17 Jul '01

[yeah, it's glibc bug time AGAIN] Hello all, I just wanted to let you all know that I found what I believe to be a glibc malloc bug. (yes, this happens even with 2.4.6 and latest Debian glibc 2.2.3-6). This is the only thing I did today, BTW. When Wine loads a very large (129 MB) exe file, it does an mmap() on it.

It only uses a new memory area in case the values get *much* larger, i.e. at least 131060 bytes. This is a BUG. (IMHO) What else should it be ?

You can't really use either. The GDI one requires calling DC_GetDCPtr which you cannot do from outside GDI, and the USER one requires a reference to a global variable that isn't visible outside USER. A possible way is to use the Escape function and add a few x11drv-specific escape codes. But first it would probably be a good thing to check how opengl32 is implemented under Windows; I have no idea how it works, but it probably needs some way to communicate with the graphics driver, and we could use the same mechanism. -- Alexandre Julliard julliard(a)winehq.com

using cvs diff
by Bill Medland 17 Jul '01

17 Jul '01

I can't see it in TFM I thought I was keeping an eye on what patches had actually been applied to the wine source (especially to see if mine had) by using "cvs diff wine". It seemed to be working but I now realise it wasn't. I guess it was diffing my local code against the corresponding revisions. How do I diff my current set of code against the current cvs? Bill

ChangeDisplaySettings
by Travis Michielsen 17 Jul '01

17 Jul '01

Hi, I was planning on implementing ChangeDisplaySettingsA soon but I'm not certain on how to do it. I have been browsing the source tree and was following the methods used by DirectDraw and was considering a similar approach. While I was browsing the source, I was eventually lead to dlls/x11drv/xvidmode.c which contains most of the functions that I will probably need. But I still have a few concerns: 1) Is the x11drv used for ddraw AND the gdi or just one? 2) what is the best way to query if the video exists? without knowing syncs? 3) and if i need to know syncs how do I find them? Another question I have is about pixel depth. From what I understand, it is imposible to change the pixel format of the screen while X is running. However, it is possible to start more than one X server with different configs (and depth) which we could use if we have to but probably not a good idea. Of course another posibility is to emulate the pixel depth, but that would probably cause performance problems, especially when used by games. Anyone have any suggestions or should we just leave changing depths as unimplemented? Thanks! - Travis Michielsen __________________________________________________ Do You Yahoo!?

fnt2bdf.c and font names
by Bill Medland 16 Jul '01

16 Jul '01

I've just been playing with fonts (sserife and vgasys) to get things working. In the process I notice that fnt2bdf seems to do some strange stuff about choosing a font name, pixel size etc. I don't want to submit a patch that merely demonstrates my stupidity/lack of understanding but am willing to put in my suggested fix. This will result in for example the MS Sans Serif 8 pt font getting a name of -windows-MS Sans Serif-medium-r-normal-sans-13-80-96-96-p-50-microsoft-cp1252 SIZE 8 96 96 as opposed to the current -windows-MS Sans Serif-medium-r-normal-sans-13-130-72-72-p-50-microsoft-cp1252 SIZE 13 96 96 (I don't understand why the 72 dpi is hard-coded) Do I submit it or am I misunderstanding something Bill

Hi, >Native msvcrt has __CxxFrameHandler, but I aggree that wine-msvcrt needs >exception facilities too. While I'm still on holiday, i just bought a laptop to do some wine coding on. I had improved the exception handling in builtin msvcrt but my last run of patches to it werent accepted due to using asm instead of register funcs. Once I get my old sources mailed to me I will begin hacking on it again. I'm interested in getting the konqueror/ActiveX stuff working with builtin msvcrt, since the dot.kde.org press release singled it out as non-functional (much to my shame <g>). Meanwhile I'm strolling through shlwapi and should have some patches for that soon. Its great to see the progress made since february though, very impressive.

Significant change to WINEPS - please test!
by Ian Pilcher 16 Jul '01

16 Jul '01

The attached patch makes a fundamental change to the way the PostScript driver deals with character encodings -- it ignores them. Instead, the driver now operates directly on 16-bit Unicode characters. This should be a more robust strategy for handling non-Latin, and especially multi-byte, character sets. I really have no idea, however, how the rest of Wine handles non-Latin characters. As an English speaker, I'm not well equipped to test it. So please give me your feedback. I particularly want to know if it breaks anything before I submit it.

Well, believe it or not the thought actually occured to me before I submitted the patch, so I actually tested it on Solaris, FreeBSD and Linux, and the only thing I had to change was the include order or stdarg.h to make it work on all platforms. The thing is that if it actually breaks on some platform it is a red light that something might be (and probably is) wrong. We can always fix it with #ifdef:s and winapi_{check,extract,fixup} or whatever can use the #ifdef to generate a correct entry for that platform if need be. Of course the more likely scenario will be that it serves as a reminder that we really can't export the C library function directly because of platform incompabillities and simply don't do it. And no, I don't believe const/non-const is a problem. Beside even if it turn out I'm wrong we can just add a "#define const /* nothing */" at the top of each externs.c file.

Re: Handling X errors using exception handlers

The main problem with that is that I don't think you can jump out of Xlib without corrupting its state. Also you'd need to properly unlock the tsx11 lock in case of exception, which will probably require an finally handler around each X call. My idea was to have the following two functions: void X11DRV_expect_error( unsigned char request, unsigned char error, XID id ); int X11DRV_check_error(void); You'd call X11DRV_expect_error before doing an X call that can fail; then if an X error happens that matches what you expect, the X error handler will simply set a flag and ignore the error (if it doesn't match you get the standard error handling). Then after the call you use X11DRV_check_error to see if your error happened or not. Would this work for what you need? -- Alexandre Julliard julliard(a)winehq.com

Wine freshman class
by Paul Gaynor 15 Jul '01

15 Jul '01

Hi, I am new to the development of wine, part of the wine freshman class :) I am really interested in developing wine for use with OpenGL hopefully to push the performance of the 3-D to window$ level. I am interested in making a striped build that just handles OpenGL strictly for gaming. Any pointers that any of you can give to get me started on my journey would be wonderfully appreciated. :) How much Win$/Linux programming experience is needed with the various tasks associated with developing wine? What are the different areas (and how much programming) is required for each task of developing wine? What do you think a good place for a beginning programmer/ developer to start? I am very excited that this group exists and I am looking forward to hacking on wine :) Paul Gaynor gpk2(a)uswest.net

What kludge? Ugly OK, that is your subjective opinion, but kludge? Even if we only see it from a purely C language perspective, it solves the problem of making sure that the C library functions have the prototypes we expect them to have. There is no other way to solve that problem that I can think of so it is certainly not a kludge. Of course you can always argue that it is a solution searching for a problem, but that is not a what I would call a kludge. Anyway, arguing about misuse of words is a waste of time and I don't think I have anything more to add that are likely to convince you. If you are not convinced now, you never will be.

I don't want to have to add a bunch of external > declaration for C library functions, that's very ugly. First of all ugly is subjective, I can't see what is ugly about it, but OK you decide what you want, so arguing that point is no use. However I'm a little curious where the documentation, and yes I'm talking about real documentation not just the external name and the ordinal, should be placed. Sure you have the underlying Unix man pages at least if we are talking about the MSVCRT and NTDLL functions, but it would be nice to have a proper Windows style man page for them eventually. Perhaps the some of the functions have some limitation in Windows that the Unix variant doesn't have (or vice versa) and thus if you extend the Winelib application you really want to know that, so the Unix man page will not really be enough. So yes, I'm really curious to know where you think the documentation should be placed. I think my solution is quite good since it solve three problem. 1. Provides somewhere to write the documentation 2. Provides a C compiler checkable prototype that can give a warning if any of the native system functions happends to have another prototype. 3. Helps tools like winapi_check a place to check things that the .spec files entries are correct. Even if you still considers it ugly, it might be worth it considering what you get. > So no, I'm not > going to apply your patch. I can't fix winapi_check properly. I can kludge it yes, but fix no. There is no implementation or anything else in the source that indicates that it is supposed to use functions from another DLL. But sure I can kludge winapi_check to ignore the atom functions and lstrcmpi in USER. The functions from the C Library is already kludged since a long time ago, so what the hell lets just add another kludge, it is only 5 new functions. If you don't apply it I don't have much choice have I.

Hi all, After reading Brandon's message I was inspired to introduce myself to this list as well. Although I have been following wine for several months now, I have just recently started wine development (only 1 small patch so far :-( ). Currently I am focusing on learning the API before I persue patches that are significantly larger, but have started a todo list. I am an avid C/C++ programmer and have experimented with serveral other languages including Java(script), Pascal, Basic, etc. I have done allot of programming for Windows/DOS in the past but when I discovered linux about 2 years ago, I immediately switched OS's and began pursuing linux programming. I do, however, still run windows occasionally, when I have trouble running programs under wine, but I believe that someday (hopefully sooner rather than latter), we will be able to use linux (and wine) to run almost every program without thought. Anyways, Welcome Brandon, and Hello All. :) Travis Michielsen __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!

The imagelist of a toolbar can be changed by the app after it has set it to the toolbar (using TB_SETIMAGELIST). In this case the bitmap number can be wrong, leading to some apps not displaying text correctly (although the bitmaps were still showing because of Wine code not really testing for bitmap number in this case). Fix for Winzip 8.0, replaces the preceding one (same problem) ChangeLog: * dlls/comctl32/toolbar.c Refresh bitmap count to take in account imagelist changes after TB_SETIMAGELIST

But if it requires a Perl > script as complex as winapi_check, especially the maintaining of the > *.api files, I'm not sure it's a win. Well the *.api files (or at least the manual maintainance of them) will be eliminated some day. I will just have to implement parsing of the "typedefs" in the headers. However, note that I'm not suggesting that we change to automatic generation of spec files right now, but at some point in the future. What tool we should for it is a later problem. With the exception of which types maps to which "kinds" (long ptr str wstr) the tool will not nessarily be very complex and I'm not sure what the parsing of typedefs to find out will be very complex either. But I wont know until I try. What primarily intrests me now is how should the needed information be stored? The problem with normal entry point is solved, the question is how the stubs and forwards should be stored? Before we know that we can't really write any working extraction tool can we? While I'm not entirely happy with your: /* ##spec## foo "@ forward bar(ptr str) BAZ.bar" */ solution it is the better that any ideas I have. Simplicity has its charm. :-) Then we could just, taking USER as example add /* ##spec## user "name user" */ /* ##spec## user "type win16" */ /* ##spec## user "heap 65520" */ /* ##spec## user "file user.exe" */ /* ##spec## user "owner user32" */ /* ##spec## user "rsrc resources/version16.res" */ /* ##spec## user "2 stub OldExitWindows" */ /* ##spec## user "3 stub EnableOEMLayer" */ /* ##spec## user "4 stub DisableOEMLayer" */ /* ... */ in a appropriate place in say dlls/user/user_main.c. The order that winapi_extract finds the directive is not important the .spec file format happends to make it possible to always get everything in the right order anyway. However this solves the header, the debug_channels, forwards and stubs problem and could be used to solve the remaining problems with "Exported external functions" but I would rather have it solved with my patch with that name, that you didn't apply when applying the other patches. So will accept such a solution? While we probably should not actually change the .c files to look like this until we have a tool of acceptable complexity that can generate the .spec files, there is quite a few preparations that need to be done before that and I would really like to have the "Exported external functions" patch applied in the meantime for other reasons like winapi_check likes to know where all the DLL:s functions are "implemented". > And it seems to me you are > finding a lot more errors in the comments than in the spec files ;-) Well, considering that our developers have neglected the comments for many year and only changing the spec files that is not very suprising. That is the problem with having redundant information, most developers only change where it really count either out of ignorance or lack of time. > > In addition it will be much easier for the developers (especially > > newbies).

The spec entry is dictated by > the dll interface, and there is no reason to change it (except maybe > to change a 'ptr' into an 'str', but this is a cosmetic issue). Well, you also have implementing new functions. You have FooA and want to implement FooW for example. It is much easier and much more natural to be able to just cut and paste without having to change the spec files. I have seen many such errors detected by winapi_check over the years.

Handling X errors using exception handlers
by Lionel Ulmer 14 Jul '01

14 Jul '01

Hi all, When discussing with Ove yesterday on #WineHQ about the handling of X errors, he told me about an idea of his : using exceptions to handle X errors. This way, when we have to explicitely handle X errors (as we will need to do for XVidmode and XDGA2 due to some (stupidly done IMHO :-) ) security fixes in XFree 4.x), we could do that using exceptions. Before doing this 'properly' (ie change the X11 drv, update the XShm error mechanism, the debugger, ...), here is what I did for now : 1) I created a new Wine-private exception type in include/wine/exception.h : /* unhandled X error */ #define EXCEPTION_WINE_X11DRV 0x80000104 2) I created a new X error handler that is installed at X11DRV initialization : static int X11DRV_XErrorHandler(Display *dpy, XErrorEvent *event) { EXCEPTION_RECORD rec; rec.ExceptionCode = EXCEPTION_WINE_X11DRV; rec.ExceptionFlags = 0; rec.ExceptionRecord = NULL; rec.ExceptionAddress = XGLErrorHandler; rec.NumberParameters = 4; rec.ExceptionInformation[0] = (DWORD)event->serial; rec.ExceptionInformation[1] = (DWORD)event->error_code; rec.ExceptionInformation[2] = (DWORD)event->request_code; rec.ExceptionInformation[3] = (DWORD)event->minor_code; RtlRaiseException(&rec); return 0; } 3) I changed the XVidMode detection code thus : /* handle only X errors */ static WINE_EXCEPTION_FILTER(xerror_handler) { switch (GetExceptionCode()) { case EXCEPTION_WINE_X11DRV: return EXCEPTION_EXECUTE_HANDLER; default: return EXCEPTION_CONTINUE_SEARCH; } } (...) void X11DRV_XF86VM_Init(void) { (...) wine_tsx11_lock(); (...) __TRY { if (!XF86VidModeQueryVersion(gdi_display, &xf86vm_major, &xf86vm_minor)) { xf86vm_major = 0; } XSync(gdi_display, False); } __EXCEPT(xerror_handler) { xf86vm_major = 0; } __ENDTRY wine_tsx11_unlock(); if (xf86vm_major == 0) { TRACE("No XVidmode\n"); return; } (...) } So what do you all think of this ? Is this something that I should add to the whole Wine tree ? The only problem with that is that it would make debugging X errors a bit more difficult as we won't have the standard X error message in debug reports from users...

You might as well put all the > information in the comment (or leave it in the current spec file for > that matter). Well, the ordinal of each function and for that that matter which functions that should be exported must be specified somewhere. Currently winapi_extract takes this information from the comment lines looking like this in the nearest preceding comment: * Foo (BAR.@) All non-static functions with such preceding comment line(s) is considered exported using the name specified in the comment as the external name. Of course, I can take this information from anywhere, but for obvious reason I can't guess it. If the unmodified source contains Microsoft Visual C++ __declspec(dllexport) directives or the project has a Microsoft Export file (a .def file) I can generate a spec file. This is not supported yet, but is no particular problem supporting in itself. A little worse problem is that I currently doesn't extract the function "kinds" (long ptr double str wstr) from the source but use the tools/winapi_check/win{16,32}/*.api files to determine the "kinds". This is not a teoretical problem, however it might take some time to fix all the same. But after that winapi_extract will be able to take unmodified source if __declspec(dllexport) directives or a .def file exists. However I think we concentrate primarily on the Wine source. I think as far the it is concerned it will suffice to use comment lines like * Foo (BAR.@) to extract the normal entries for the spec files. The stubs and forwards need to have special handling but then so must it in the case of __declspec(dllexport) directives or a .def file as well. There is no problem for winapi_extract to support all the above either (except implementation time of course). > Basically, if the source parsing allows doing more than we do now > (like build spec files for new dlls) it's worthwhile; if all it does > is generate the existing spec files some other way I don't think > there's much point.

Sure winapi_check can (and indeed was the original reason for it) find missmatchs. But given the number of errors I have seen people make that winapi_check detected, we really should avoid having redundant information if we can. In addition it will be much easier for the developers (especially newbies). If you change the prototype in the .c files or the ordinal in the comment above it, it will be enough.

IMO, this is true if we can make the generator work purely on the source code, so that you can give it the unmodified source of a Windows dll and it spits out the spec file. If you need to add comments before each and every exported function, then I don't see much advantage to parsing the source. You might as well put all the information in the comment (or leave it in the current spec file for that matter). Basically, if the source parsing allows doing more than we do now (like build spec files for new dlls) it's worthwhile; if all it does is generate the existing spec files some other way I don't think there's much point. After all, we have the spec files already, and they are not going to change much. Another use of the source parser could be to generate more detailed debugging information for +relay; but in this case I'd say it should go to a completely different file, used by some external relay dumping program. I don't want all the extra debug information to clutter up the spec files. -- Alexandre Julliard julliard(a)winehq.com

hello all

Hi everyone, Just letting you all know that there's a new listener out here, eager to pick up on what you're discussing. I'm only 17, so I'll be pretty much staying out of the way, but I love programming so hopefully you won't mind if I stick my hand up to ask a question or respond to someone every once in a while. Just so you can know a bit about me...I used to be a purely QBasic programmer in my "early" days, but a few years ago I began broadening my horizons, mostly with HTML and Visual Basic. For a long time I had wanted to learn C but never really got around to it, but a little over a year ago I finally sat down and started learning, and now its one of the only languages I ever use. Some other languages I currently program in (or would come back to me if need be :-) : C/C++/Visual C++ (Q)Basic/Visual Basic HTML Perl BF (there's an interesting language...) Java/JavaScript WISE InstallMaster scripting ;-) Anyways, I'll let you all get back to the important development discussions. I'll be talking to you... - Brandon

The #if 0 #endif or having to have a documentation comment at all? Anyway the #if 0 is not needed I thought it might be needed in some cases but it is not. I mistakingly believed it might be type conflicts but it can't be since any exported function must of course use the C library types otherwise you can't export them directly. If you are refering to the documentation comment, I can't really see why. All other functions have it and adding additional documentation might be a good idea in some cases as well. Furthermore the extern declaration makes it possible for the C compiler to check that the prototype is the same as the prototype in the included files. I spotted several error when doing the patch because of this. As hinted above, I have implemented a working solution that does what I have described above. See separate mail. > As long as we require comments, we might as > well put everything explicitly in the comment, something like: > > /* ##spec## msvcrt "@ cdecl strcpy(ptr str) strcpy" */ > > (we can probably come up with a better syntax, but you get the idea). > Then we can simply grep for '##spec##' and extract everything into the > spec file.

I don't like it very much but it is acceptable. But we need not decide that now. I will think more about it and come back later with some kind of proposal that might or might not match yours. I'm not sure, we will see. For normal entry point, however, I respectfully disagree. One of the major reasons of having automatically generated .spec files is to avoid having to store redundant information. The needed information is already in the C function declaration and storing in a comment as well brings us back to the current situation. Sure it makes that generator less complicatated but it really isn't that important as long as it is reliable and not ambigeous. PS. For the record: I consider winapi_extract a prototype not something that nessary will finally use in "production". We might of course use it, but I would rather rewrite it so it becomes simpler and more reliable. Perhaps it shouldn't be in Perl but in C instead? Oh, well, that is a minor issue compared to how the information should be stored.

To strip or not to strip
by Jeremy White 13 Jul '01

13 Jul '01

We've always built the CodeWeavers Wine RPM unstripped, in the theory that it made supporting Wine newbies easier. However, AFAICT from watching cemw, we never get into a situation where a newbie goes into winedbg; more often, they shift first to the CVS tip, and from there maybe to winedbg. So, it seems like shipping debug symbols may just be a waste of bandwidth. (Note, we build with all full logging enabled, and we'll never change that). However, before we go ahead and yank the debug info out of our RPM, I thought I'd post a note, and let someone tell me if I'm wrong. Thanks, Jer

That's quite ugly IMO. As long as we require comments, we might as well put everything explicitly in the comment, something like: /* ##spec## msvcrt "@ cdecl strcpy(ptr str) strcpy" */ (we can probably come up with a better syntax, but you get the idea). Then we can simply grep for '##spec##' and extract everything into the spec file.

I didn't even thought of that particular problem. Functions like strcpy is currently suppressed by having it listed in tools/winapi_check/nativeapi.dat, but that is a little kludgy. [Thinking...] Well you could simply have an function documentation comment without a function implementation in some file that belongs to MSVCRT. Like: /*********************************************************************** * strcpy (MSVCRT.@) */ #if 0 /* Suppress warnings */ extern char *strcpy(char *dest, const char *src); #endif Perhaps we could do the same with atom functions and lstrcmpi? The #if 0 #endif isn't even needed for them I believe. > > I think that we need to move the solution of this problem one step > > up the "ladder" and discuss the more general problem: > > How should we store the information needed to generate > > the spec files in the source, especially concerning > > the forwards and stubs? > > You'll need a file somewhere that specifies all the entries that > cannot be determined automatically from the source. You simply cannot > build a 100% correct spec file based only on the function comments. Yes. I have some ideas, but no really good one. My currently best suggestion is having a .spec.in file that approximately looks like the .spec files but supports configure like substitutions. foo.spec.in: ---8<--- name foo type win32 init @init@ rsrc foo.res import baz.dll @debug_channels@ 101 forward Bar BAZ.Bar 102 stub BarFoo @fixed@ @ forward Foo BAZ.Foo @ stub FooBar @unfixed@ ---8<--- And simply let winapi_extract or whatever simple substitute @init@, @debug_channels@, @fixed@ and @unfixed@ with what can be extracted from the source. > And you definitely do not want to need to parse KERNEL source files > (like the ones in memory/) to build the USER spec file. Of course. The question was whether the memory directory belongs to USER or not. I have now accepted that it does not.

Actually no, the atom functions are similar to lstrcmpi, they are exported from kernel so we don't need to link to libkernel32.so to get them (and they shouldn't have USER comments either). The real problem is the internal kernel functions called by user, things like THUNK_Alloc or LOCAL_Alloc. > The problem is that if I say that the memory directory doesn't > "belong" to dlls/user/user.spec winapi_{check,extract,fixup} will > not find implementations for all functions, which will cause > problems. > > For example how should winapi_extract know that I should generate the line > 471 pascal16 lstrcmpi(str str) lstrcmpiA > when it generates the spec files? Well, it's a more general problem, namely that the spec files can reference functions that are not implemented directly in the dll. You also have for instance: @ cdecl strcpy(ptr str) strcpy in MSVCRT, and strcpy is clearly not implemented there since it's in the C library. So you cannot assume that only the functions contained in the dll can be used in the spec files, it is legal for the spec file to reference external functions. > I think that we need to move the solution of this problem one step > up the "ladder" and discuss the more general problem: > How should we store the information needed to generate > the spec files in the source, especially concerning > the forwards and stubs? You'll need a file somewhere that specifies all the entries that cannot be determined automatically from the source. You simply cannot build a 100% correct spec file based only on the function comments. And you definitely do not want to need to parse KERNEL source files (like the ones in memory/) to build the USER spec file. -- Alexandre Julliard julliard(a)winehq.com

The problem is that if I say that the memory directory doesn't "belong" to dlls/user/user.spec winapi_{check,extract,fixup} will not find implementations for all functions, which will cause problems. For example how should winapi_extract know that I should generate the line 471 pascal16 lstrcmpi(str str) lstrcmpiA when it generates the spec files? Of course the automatic generation of spec files is not 100% complete most importantly handling of forwards and stubs is not supported. I think that we need to move the solution of this problem one step up the "ladder" and discuss the more general problem: How should we store the information needed to generate the spec files in the source, especially concerning the forwards and stubs? I will address this issue in a separate mail, but you are welcome to add comments specific to this problem in this thread, I'm not sure I feel to writing it today. I have been postponing the writing of mail for quite some time and I'm currenly beginning to get rather tired. PS. Why not as an interim solution simply add support for forward in the Win16 spec files so 471 pascal16 lstrcmpi(str str) lstrcmpiA becomes 471 forward lstrcmpi(str str) USER32.lstrcmpiA which winebuild until actual need simply interprets as 471 pascal16 lstrcmpi(str str) lstrcmpiA Hmm. Perhaps we should have forward16 and forward to separate the pascal16 and pascal cases? Anyway this gives winapi_{check,fixup} enough information to handle the situation where the memory directory doesn't "belong" to dlls/user/user.spec.

No, USER does not use the memory directory.

Theoretically this could cause trouble when used with a computer having no connection to the Internet, as an app could think it can connect, try to do it, fail and terminate or display annoying messages. It's not really a strong objection, as most decent computers are connected to the Internet these days, but maybe a config option could be better ? Just a thought. Gerard

CreateWindow issue?
by Bill Medland 12 Jul '01

12 Jul '01

Can anyone shed any light on this? 1. If I take Petzold's POPPAD1 project and slightly modify it so that the style is WS_CHILD | WS_BORDER | WS_VISIBLE | ES_AUTOHSCROLL and then spy on the WM_NCCREATE and WM_CREATE it tells me that the style passed in is WS_OVERLAPPEDWINDOW | WS_CHILDWINDOW | WS_VISIBLE | ES_AUTOHSCROLL which is not the same thing. Does anyone know if a. The Windows Spy++ is telling fibs b. (Win95) CreateWindow patches them up in some way. 2. (Why I was even looking at 1) In the application I am working on we open Edit controls almost as above inside dialogs and they appear with a single pixel solid frame under Windows whereas under Wine they appear with a 2-pixel sunken frame. There are several changes I can make in the controls/edit.c to get the same behaviour under Wine but so far they all "mess up" normal sunken ones. (Under windows the resulting windows end up with zero extended style and 50000088 style.) Any thoughts would be appreciated. Bill
