NG: Wine and cyrillic input and output ?
by Dmitry Timoshkov 25 Sep '01

25 Sep '01

Hello all. This patch fixes a couple of problems with keyboard group switching reported in the news group: 1. Group switch had never worked before, if the keyboard has been switched outside of Wine. 2. I was clearly stated that Group switch is active if event->state & 0x2000, not event->state & 0x6000. Please test it on your local configurations and report back. If there will be no objections, I'll send it to wine-patches. Thanks. -- Dmitry.

GetClipboardData
by Dominik Strasser 25 Sep '01

25 Sep '01

Hello, with MS WinWord I am encountering the following problem: If there's something selected, GetClipboardData is called. In GetClipboardData, there is the line: HWND hWnd = (hWndClipWindow) ? hWndClipWindow : GetActiveWindow(); hWndClipWindow is 0, so GetActiveWindow() is called which also returns 0. I tracked this down to PERQDATA_GetActiveWnd returning 0. This leads later to "w" bening 0 which results in an X error calling XConvertSelection. It happens in all modes, desktop managed, non managed. Does anybody have any clues ?

Callwave doesn't run
by Steven Walter 23 Sep '01

23 Sep '01

Is this a known problem? When I try to run the callwave install program, or the callwave program itself, I merely get: fixme:win32:PE_CreateModule Security directory ignored err:seh:start_debugger Couldn't start debugger (debugger/winedbg 134640112 24) (2) Read the Wine Developers Guide on how to set up winedbg or another debugger Is this a configuration error on my part? Either way, is there some information I need to give to get this fixed? I appreciate it.

VWIN32_DIOC_DOS_INT_13 is not really different from int 13, so it wouldn't make much difference either way. Much better would be to implement the higher level calls that are needed to reimplement the DOS interrupts; for instance int 13 should use the IOCTL_DISK calls of DeviceIoControl, int 25/26 should be replaced by Win32 device access (CreateFile("\\.\PHYSICALDRIVEx")+Read/WriteFile), etc. -- Alexandre Julliard julliard(a)winehq.com

The reason they're here at all is because the x11drv enumerates fonts with these charsets and I'm claiming that this is a bug, since no application can be expected to know that these numbers mean. Now there is a RUSSIAN_CHARSET and this gets handled by the TranslateCharsetInfo before the switch. Huw.

re-implementing real mode interrupts
by Mike McCormack 21 Sep '01

21 Sep '01

Hi, I was wondering if it would be a Good Thing to start re-implementing real mode interrupts using Win32 calls. For example, currently calling DeviceIoControl VWIN32_DIOC_DOS_INT_13 on the VWIN32 device calls to the real mode interrupt INT 13. It could be re-implemented so that INT_Int13Handler does a DeviceIoControl and the low level disk access code moved into the VWIN32 device implemetation. This would better seperate the DOS and Win32 implementations. Any thoughts?

GetSystemMetrics / SetSystemMetrics ?
by Andriy Palamarchuk 20 Sep '01

20 Sep '01

Question: How to update metrics data returned by GetSystemMetrics function? Problem: Currently I'm implementing some easiest FIXMEs (e.g. SPI_GETSHOWSOUNDS) in function SystemParametersInfo. GetSystemMetrics is used to return information for a few types of SPI_GETxxx actions from this function, including the action I'm working on. Logic for corresponding SPI_SETxxx actions is not implemented and contains commented out calls to SetSystemMetrics. As I understand this comment is a mark that corresponding GetSystemMetrics data should be updated in this place. GetSystemMetrics returns data from array sysMetrics. I did not find any function which provides update access to the array. Can you advise how to deal with this problem? Regards, Andriy Palamarchuk

Quicktime 5.0.x / XVideo usage
by Matthias Dahl 20 Sep '01

20 Sep '01

Hey there... ]) powered by Linux 2.4.8 ([ I have discovered some strange behavior with WINE and Quicktime 5.0.x. As long as the "time slider" and the "audio bars" are being updated the video runs quite sluggish. But if you open a menu or a dialog box both the "time slider" and the "audio bars" stop updating - which is normal. BUT the video itself runs at full speed as long as both are not being updated. Which is kinda strange I guess. Even those animation content which is included with some movs doesn't slow the playback down, so it cannot be a performance issue. (on PIII with 500 Mhz, 256 MB ram and X 4.1.x (G400MAX)) Also if you maximize the video to full screen or anything that is not its original size, the playback also becomes very sluggish. Doesn't WINE use the XVideo protocol for such operations? By the way. I am using yesterday's CVS checkout without any windows DLLs. I'll happily provide more informations - just let me know what you need. Last but not least.

Of course the only way to be sure is to really look at > the actual warnings... well, the warnings I looked at come of three kinds (for that's for from being exhaustive): - comparing the dwSize of a struct with the sizeof of the struct. The first being a DWORD, the second of type size_t. Using the macro means using a cast here, which I find rather ugly - comparing an unsigned int with an explicit integer : min(4, u). This could be rewritten easily into min(4u, u) for example - real potential problems with comparing unsigned char with signed short for example. IMO, the first two ones shouldn't require type casts. last but not least, I think that the basic issue here is that gcc should report a sign mismatch in the comparison... and it doesn't.

I have looked at your source. With current Wine, expose X events are retrieved from the X server when Wine has nothing else to do. These events are setting the update region. CreateWindow does not set the update region in current Wine, even if the window is visible. This is the point that matters for your problem I think. hSplash = CreateDialog (hInstance, MAKEINTRESOURCE(IDD_SPLASH), NULL, Splash_DlgProc); SetForegroundWindow(hSplash); // here the update region is nil (Wine problem !) UpdateWindow(hSplash); // --> nothing is displayed. Sleep(5000); // events are retrieved from the X server queue. printf("Removing splash.\n"); DestroyWindow(hSplash); Your code does not display anything because no message is retrieved from the message queue. After the Sleep call, WM_PAINT messages are available, but as you don't retrieve them by calling PeekMessage or something like that, nothing is shown. I don't want to say that your app code is wrong, of course. There is a problem in Wine, but I don't know what to do about it. My first thought would be to scan the X queue and retrieve the expose events as was done before the great changes of this summer, but this may be somewhat difficult to do right. I prefer to waste my time searching for other problems, because I have no doubt that Alexandre Julliard is aware of this one and it's clear that he is not finished yet with X code reorganization.

It's not acceptable to depend on a > library that would impose extra conditions on the Wine/Winelib > user. The problem is what constitutes extra conditions is extremly vague. If you have a Winelib application that don't for example use say any crypto functions, you really can't be said either to use or to derive a new work from a completely unused and/or unnessary library. If you do use any crypto function, well, whether that imposes any extra conditions is an extremely difficult legal issue that really can't be answered without a real court case. It might depend on whether the use is optional but it might not. That is what I have been trying to point out in my recent messages. So just saying that "I don't want any libraries that imposed extra conditions on the Wine/Winelib user" is not really a very informative answer. What you mean is (I guess): 1. No use of libraries under the GPL or other viral licenses 2. No use of commersial libraries (end user and/or developer must pay for it) Or do you mean something else? Anyway see below. > And this is not solved by having a choice between two different > sets of extra conditions. Note that you always have the choice of NOT using crypto. If Wine didn't include a working crypto implementation that would be the only choice wouldn't it? As long as it doesn't effect the performance or maintainabillity of Wine in negative way more choices are always better than less IMHO.

It is not the effort that is the real problem. The problem is that since ADVAPI32 might use libgcrypt (that is GPL:ed library) it possible to for a non-GPL:ed Winelib application to indirectly via the ADVAPI to "link" to libgrypt. This would violate the GPL:ed in some meaning. Of course the authors of the Winelib application might be entirely unaware of this fact but it is still teoretical violation. This is, of course, in some meaning absurd, but ask yourself this: What meaning have the GPL for libraries if you can just wrap a intermediate library with a GPL compatible license (like Winelib:s ADVAPI "library") around it and circumvent the GPL? Of course a distinct possibility exists that a court of law will find that the GPL (as applied to libraries) is meaningless or at least meaningless in the case of Wine. But are you willing to be the defendent in a test case? Alexandre is not. Still IMHO even in the worst case what will likely happend is that. 1. Richard Stallman (or somebody else) sends a GPL violation notice. 2. Slashdot debate the case and possibly hang us out. :-) 3. We will discuss on the list what to do and possible remove the offending code. 4. If we do not the debate on Slashdot and elsewhere will continue 5. If we still persist the chances that we will be sued is still quite small since A) The cases of winning is close to zero B) There is little or no chance to profit even regardless of this. Of course there is moral aspect of this but ask yourself this: "Is it immoral to shatter somebodies unrealistic expectations?" In short there is no legal risk at all IMHO but Alexandre has said earlier that he doesn't want code using GPL:ed libraries if not to protect himself or the Wine project, so to protect possible users of Wine if not from legal issues so from bad PR. > There's also something to be said for following Microsoft's API for > crypto back-ends, so that proprietary back-ends (i.e. those > dealing with > hardware keys, etc.) could function within the wine cryptoapi > framework. > In this case, each individual provider (RSA, DSS, etc.) would then be > implemented either in terms of gcrypt, or OpenSSL, or libcrypt, or any > other. That is probably a good idea. But you can't use libgcrypt at least not without asking the libgcrypt authors if it is OK that Wine(lib) uses libgcrypt despite the fact that it makes it possible for non-GPL:ed Winelib applications to indirectly use libgcrypt. And you better ask Alexandre whether is OK with him to include the code under such circumstances.

If we only permit linking with libraries that have GPL compatible licenses, we will seriously limit our choices. Sure I, since GPL is a dominant license, fully agree that all linking to non-GPL:ed libraries should be optional. Of course the question of what is optional is vague too. See below. Also note that this is an entirely different issue than the issues concerning GPL:ed libraries. In the case above it is 100% clear that only the distributor of the GPL:ed application can have any legal liabillities for possible violation of the GPL. It is not out immediate concern. Beside since they, because of the GPL, must have the source code they can always disable things like crypto that might not have a 100% GPL compatible Winelib implementation. In short. GPL:ed Winelib applications is not our concern and we shouldn't IMHO make it one beyond making sure that all linking to non GPL compatible libraries is optional. GPL:ed libraries is, as said above, a different story, that from a legal point of view is an unresolved issue. The "answer" of that question regardless of what it will be, will, be very important since it might, unless it is too vague, define the boundaries of copyright in a more definite way. However, I'm a little afraid of that for the GPL to be truely meaningful, especially in the case of Wine, you will have define the boundaries of copyright a little to strict for my liking. > Since the number of GPLed Windows apps that do not have Linux > counterparts is vanishingly small, the OpenSSL option seems to > me more appropriate than using a libgcrypt back end.

Of course but that is not our immediate concern, the same would be if we link with any proprietary library. Any distributor of such libraries whether in conjuction with Wine(lib) or seperately must of course fullfull the licensing requirements of such libraries (including but not limited to pay any license fees). Actually in some meaning we already do, since proprietary implemenatations of both X Windows and OpenGL exists and Wine(lib) will happily dynamically link with them and use them if they exists. Wine(lib):s use of them obviously do not gives any license to distribute them, but that is not our concern. This of course raises they question if we mandatorily link to libraries, like X Windows or OpenGL, that both have GPL and non-GPL compatible implemtations: Do we optionally or mandatorily link to a non GPL compatible library? Does this matter from a legal perspetive as concerning whether a Winelib user violate the GPL or not? In addition does it matter whether the GPL compatible library is: 1. Complete 2. Close to complete 3. Has only basic functionallity 4. Unusably buggy 5. Unimplemented stubs 6. In the planing state 7. A theoretical construction In that case why?

DDE and postmessage
by eric pouech 16 Sep '01

(mainly for Alexandre) I've started looking at the inter-process DDE message management as of today, PostMessage doesn't use the packing strategy used by SendMessage (rightfully because of possible dangling pointer issue if pointers are used in message parameters) however, some DDE messages need to send additional information even when posting (copying all data), and DDE protocol requires posting messages (SendMessage is banned) do you have any plan to handle this ?
