16-bit and 32-bit separation
by Patrik Stridvall June 18, 2001

June 18, 2001

[Since the subject it up because of Dimitry's "Move 16-bit COMM stuff to USER, where it belongs" patch] My new tool winapi_fixup could without to much effort be extended to facillitate separation of 16-bit and 32-bit stuff by moving the 16-bit parts of a file (example: foo.c) to a new 16-bit only file (example: foo16.c). Of course because of dependecies, includes and such things it can only be partly automatic and it will in most cases require quite a lot editing afterwards, so the questions (primarily to Alexandre but other replies welcome to) are: 1. Will/Should Alexandre accept such patches at all? 2. Is it a useful effort to get the 16-bit stuff out of the way so we don't have to see it in the files when editing the 32-bit stuff? 3. Is it a useful effort to make it possible to have --disable-win16 configure option to compile out as much Win16 stuff as possible in order to save space in the binaries for say embedded stuff. 4. While this certainly it not a high or even medium priority effort, should it have low, very low or extremly low priority? PS. I have other stuff planed so I certainly do not lack things to do. However since the subject is up I might just as well ask.

SIGSEGV while trying to run Word97
by Heiko Nardmann June 17, 2001

June 17, 2001

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am continously getting a dialog "Nicht genügend Arbeitsspeicher oder unzureichender Speicherplatz, um Word auszuführen" (German version). After trying to examine this problem with debugmsg all (without real success) I added an strace call to the whole call. This resulted in a log file which tells me that a SIGSEGV occurrs. Here is a part of the strace log file which contains the SIGSEGV message. After that the appropriate 'debugmsg all' part follows. What can be done to shed more light onto this problem? strace log: write(2, "08069280:trace:win32:_LeaveSysLe"..., 112) = 112 write(2, "08069280:Ret user32.CreateWindo"..., 68) = 68 write(2, "08069280:RET mso97.486: _MsoCre"..., 84) = 84 write(2, "08069280:trace:heap:HeapFree (40"..., 74) = 74 write(2, "08069280:Call kernel32.GetVersio"..., 49) = 49 write(2, "08069280:Ret kernel32.GetVersio"..., 65) = 65 write(2, "08069280:Call kernel32.GetVersio"..., 60) = 60 write(2, "08069280:Ret kernel32.GetVersio"..., 68) = 68 write(2, "08069280:Call kernel32.GlobalMem"..., 65) = 65 time(NULL) = 992531763 time(NULL) = 992531763 open("/proc/meminfo", O_RDONLY) = 11 fstat(11, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x4035c000 read(11, " total: used: free:"..., 1024) = 319 read(11, "", 1024) = 0 close(11) = 0 munmap(0x4035c000, 4096) = 0 write(2, "08069280:Ret kernel32.GlobalMem"..., 73) = 73 write(2, "08069280:CALL mso97.394: _MsoFCr"..., 147) = 147 write(2, ") ret=30011010\n", 15) = 15 write(2, "08069280:Call kernel32.VirtualAl"..., 86) = 86 write(2, "08069280:trace:virtual:VirtualAl"..., 68) = 68 mmap2(NULL, 131072, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOSYS (Function not implemented) old_mmap(NULL, 131072, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40e90000 munmap(0x40ea0000, 65536) = 0 write(2, "View: 40e90000 -

CS_PARENTDC problems
by Malte.Starostik＠t-online.de June 17, 2001

June 17, 2001

Hi, we had some serious painting problems with dialog from an ActiveX control. All controls were invisible and only showed up sometimes on getting or losing focus. The cause is a custom class "_BitmapClass" that draws a logo and has the CS_PARENTDC class style (and no other class styles FWIW). Its WM_ERASEBKGND handler fills the complete dialog rect with that default Win95-Desktop-Background colour. According to the Win32 docs winelib behaves correctly wrt CS_PARENTDC and clipping. In this case it'd be Macromedia's fault as to how they implemented that window. However, I just found http://msdn.microsoft.com/library/techart/msdn_classy32.htm: <classy> If you use the CS_PARENTDC style for a class, each window in that class uses its parent window's DC. CS_PARENTDC is similar to CS_CLASSDC in that multiple windows share one DC. In CS_PARENTDC, however, the windows that share the DC need not belong to the same class. </classy> This contradicts the API docu at http://msdn.microsoft.com/library/psdk/winui/winclass_3b1v.htm: <api docs> CS_PARENTDC Sets the clipping rectangle of the child window to that of the parent window so that the child can draw on the parent. A window with the CS_PARENTDC style bit receives a regular device context from the system's cache of device contexts. It does not give the child the parent's device context or device context settings. Specifying CS_PARENTDC enhances an application's performance. <api docs> a little later, this is as near as the "classy" text comes to clipping: <classy> Another outcome of the CS_PARENTDC style is that child windows can draw anywhere in their parent's client area as well as drawing in their own client area. The CTL3D library, which creates 3-D effects around edit controls and list boxes, relies on this behavior. An application should not use CS_PARENTDC if it needs to adjust the mapping modes for different child windows. This will negate much of the benefit and could cause problems ensuring that each child window has the correct mapping mode set. </classy> Then I tried on Windows (2000), created a window with a child that has CS_PARENTDC set and * The paint rect of the PAINTSTRUCT as intialized by BeginPaint() equals the window's client rect - as expected. * but - surprise - so does the DC's clip box and trying to largen it to cover some or all areas of the parent fail and of course any drawing on the parent fails. * same for the DC returned by GetDC(hWnd) * only GetDCEx(hWnd, 0, DCX_PARENTCLIP) returns a DC that allows painting on the parent (no difference to a non-CS_PARENTDC window though) So, how is this painting on the parent with that style flag supposed to work? The things above make me think that it isn't possible at all or requires some additional steps. This would at least explain why the dialog described above looks busted in wine. If anyone could confirm my observations I'd come up with a patch. Thanks for any info, -Malte -- Wars don't determine who's right, only who's left.

Hangs in half-life menus (design problem in new queue code)
by Ove Kaaven June 14, 2001

June 14, 2001

The new message queue code has caused the half-life menus to hang, since it handles timers slightly differently now. Now: - User moves mouse over a menu item - On mouseover, game starts a window timer (55ms) - On each WM_TIMER, game redraws the menu item. This takes longer than 55ms - After drawing, it checks messages. Since the 55ms timer has expired, another WM_TIMER is received, item is redrawn, any user input is ignored. Repeat Before, the hardware input queue was checked before WM_PAINT and WM_TIMER was checked, so the user could move the cursor away from the menu item (which would cancel the timer). With the new code, the hardware input queue (x11drv.MsgWaitFor...) is checked *after* timers, so the menu is now completely stuck. The new message queue design doesn't seem to allow this to be fixed... or does it?

RE: wine on Alpha (was: Help needed)

June 14, 2001

> > Still, you must be aware of a few thing. > > * Wine is not 100% byte order clean. > > Alpha seems to be "correct" endian ;) True. But what I meant was since the size of integer changes from 32 to 64 bits, any code that rely on the exact layout of memory might have problems becuase of this. This is not the same as the problem below where you have pointer truncation issues or because code expects that DWORD x; int y; x = y; will work correcly. But OK. I shold probably explained better what I meant. Anyway all code should be byte order clean regardless and making it so might solve some 32/64 bit byte layout problems as well. When you change to code for Alpha you might as well change it to work with big endian platforms as well. > > * Wine is not 64 bit clean. > > This is a little worse especially since > > Win32 often stores pointers in 32 bit integers > > and this problem really can't be solved in > > a good way, since extending the size of the storage > > is not possible at least not if you want to > > be able to implement a x86 emulator in the > > future.

True, but Wine might need something a little more than that and FX!32 doesn't have souce code available AFAIK. Of course that is perhaps not a problem for an internal Digital project. :-) Anyway, that is a later problem. Just making Winelib work might take some effort.

A sample or something to plagiarize from would be good, I think. I haven't figured out how to work mingw either, but maybe inspiration will come.

I'm sorry for not answering earlier. I saw your message but I didn't have time to answer it at the time and then a forgot about it. In truth I wasn't very eager about answering either since I have answered far to many people that just asked questions and then didn't contribute anything because I guess that they felt it was to difficult or to much work. I didn't notice that you were from Digital either, but after reading Kernel Cousin Wine #97 I was made aware of that fact. While it is possible that you are yet another of those people I talked about above, since you are from Digital I will take some time to answer your questions. Note however that I'm not at all unwilling to answer questions. It is just that it has felt like a wasted effort in the past. > We are planning to port wine onto Tru64 Unix. I have some > basic Questions. OK. Sound good. > Can you tell me how to go about it. Yes. But it is better if you ask more specific questions. > How do we start. You try to get it to compile and link. This shouldn't be to difficult. While I never used Tru64 I expect it supports all things Wine will need. > How big > is the task and Well, if you want the emulator (Wine) to work it will be a humongous task, since you will have to emulate x86 instructions on the Alpha among other things. However if you just want the porting tool (Winelib) to work it will be a little easier. Still, you must be aware of a few thing. * Wine is not 100% byte order clean. However there have been some attempts to port it to Sparc which is big endian so don't if I think it is that bad and the remaining problems can be fixed without to much effort. * Wine is not 64 bit clean. This is a little worse especially since Win32 often stores pointers in 32 bit integers and this problem really can't be solved in a good way, since extending the size of the storage is not possible at least not if you want to be able to implement a x86 emulator in the future. However I guess it will be possible to force all memory usage to be in the lower 32 bits of memory to be able to cope with truncated pointers. * Then of course you have Tru64 specific problem. However I don't expect them to be so bad. > how to start about it.. Well as I said. Try to compile and link it. Then try to get some of the simple examples in wine/programs to run.

Re: virtual memory problems with Linux 2.4.5

Mike McCormack <mike_mccormack(a)start.com.au> writes: > your patch produced a yes, BUT when i changed the offset value to > 0x400, and it failed ... see new patch below. That's a bug in glibc 2.1.3. This is from the mmap64 source: [offset is in ecx:edx] testl $0x3ff, %edx jne L(einval) shrdl $12, %ecx, %edx /* mmap2 takes the offset in pages. */ shrl $12, %ecx But of course 0x3ff only tests 10 bits, not 12, so if bits 10 or 11 are set they will be silently dropped. This has been fixed in glibc-2.2. Another related problem is that even without this bug, mmap64 will always refuse to do an unaligned mmap, even if the kernel might have accepted it (with kernel 2.2.x for instance). Maybe the best solution would be to directly call the mmap syscall instead of mmap2 when mapping executables, this would fix both problems. -- Alexandre Julliard julliard(a)winehq.com

Well, not exactly; the release will be made once I no longer have any bug reports to work on. So if you feel the code is not ready for release, you better send me bug reports... So far the things I'm working on are: - ScrollWindow doesn't always get exposure events - client rect must be empty for zero size window - must create X window before WM_NCCREATE - hardware events priority order is messed up - ControlSpy refresh (?? needs more details) So if you see problems that are not listed here, you have to report them or they won't get fixed before the release. -- Alexandre Julliard julliard(a)winehq.com

Missing functionality in mmaux
by Florian Bauer June 12, 2001

June 12, 2001

Hi, I tried to run Naturally Speaking, a speech recognition software under wine without a real windows installation. It installs just fine, but when I try to run it, it tries to adapt the audio settings. That fails, and I get the following fixme's from wine: fixme:mmaux:MIX_GetLineInfo Unhandled component type (00000007) fixme:mmaux:MIX_GetLineInfo Unhandled component type (00000008) I looked at the sources, and it seems that this is due to missing case clauses in the function MIX_GetLineInfo in mixer.c . Unfortunately, I don't know enough about C programming and the Windows and OSS API's involved to add the missing parts myself. Is it likely that this will be fixed soon? I would love to use NatSpeak under linux, because then I could delete my Windows 98 Partition... Anyway, keep up the good work regards Florian

Problems with GetFileVersionInfo[Size]()

June 11, 2001

Hi, The Shockwave ActiveX control I'm loading tries to read the VERSIONINFO resource from my winelib app. AFAICS it subsequently crashes because that fails. Anyway, there seems to be a problem: char path[PATH_MAX]; GetModuleFileName(inst, path, sizeof(path)); kdDebug() << "GetModuleFileName: " << path << endl; DWORD dummy; kdDebug() << "GetFileVersionInfoSize: " << GetFileVersionInfoSize(path, &dummy) << endl; kdDebug() << "GetLastError: " << GetLastError() << endl; outputs activexproxy: GetModuleFileName: Y:\src\kde\build\kdenonbeta\activexproxy\proxy\activexproxy activexproxy: GetFileVersionInfoSize: 0 activexproxy: GetLastError: 0 which means it obviously doesn't find the resource. (btw, why is GetLastError() 0 here?) However, this code suceeds (inst is the HINSTANCE passed to WinMain()): HRSRC ver = FindResource(inst, MAKEINTRESOURCE(VS_VERSION_INFO), MAKEINTRESOURCE(VS_FILE_INFO)); kdDebug() << "FindResource: " << ver << endl; int size = SizeofResource(inst, ver); kdDebug() << "SizeofResource:" << size << endl; HGLOBAL mem = LoadResource(inst, ver); void *buf, *block = LockResource(mem); UINT len; VerQueryValue(block, "StringFileInfo\\040904b0\\FileDescription", &buf, &len); kdDebug() << "Description: " << reinterpret_cast<WCHAR *>(buf) << endl; FreeResource(mem); the output is: activexproxy: FindResource: 1078760168 activexproxy: SizeofResource:608 activexproxy: Description: ActiveX-Proxy for Konqueror So basically the code GetFileInfoVersion[Size]() use to load a library fail if the given path is the winelib app (the symlink to wine) itself :( Thanks, -Malte -- Wars don't determine who's right, only who's left.

wine binary loader problem - incorrect code at entry point
by Mike McCormack June 11, 2001

June 11, 2001

Hi, Using the latest CVS, i'm trying to run the Adobe acrobat installer program (ar500enu.exe) and it crashes without doing anything at all. i have traced the problem to bad code at the program's entry point... which presumably means that the wrong piece of the program was mmapped into memory. i have run this program before using wine, (not recently though) and it has worked. Other programs (such as the netscape installer) at least start up and get going before crashing in a similar way. Mike from the debugger: 0x0040c110 (<Debugged process>.EntryPoint in <Debugged process>): decl 0x0(%edi) Using Sang Cho's disassembler i get: //******************** Program Entry Point ******** :0040C110 55 push ebp Disassembly of File: ./c/ar500enu.exe T.DateStamp = 351A66B8: Thu Mar 26 06:31:20 1998 Code Offset = 00000400, Code Size = 00010E00 Data Offset = 00011800, Data Size = 00003200 Number of Objects = 0005 (dec), Imagebase = 00400000h Object01: .text RVA: 00001000 Offset: 00000400 Size: 00010E00 Flags: 60000020 Object02: .rdata RVA: 00012000 Offset: 00011200 Size: 00000600 Flags: 40000040 Object03: .data RVA: 00013000 Offset: 00011800 Size: 00003200 Flags: C0000040 Object04: .idata RVA: 0001A000 Offset: 00014A00 Size: 00001000 Flags: C0000040 Object05: .rsrc RVA: 0001B000 Offset: 00015A00 Size: 0000A400 Flags: 40000040 and from the trace i get: trace:module:PE_LoadImage loading C:\ar500enu.exe trace:module:map_image mapped PE file at 0x400000-0x426000 trace:module:map_image mapping section .text at 0x401000 off 400 size 10e00 flags 60000020 trace:module:map_image mapping section .rdata at 0x412000 off 11200 size 600 flags 40000040 trace:module:map_image mapping section .data at 0x413000 off 11800 size 3200 flags c0000040 trace:module:map_image clearing 0x416200 - 0x417000 trace:module:map_image mapping section .idata at 0x41a000 off 14a00 size 1000 flags c0000040 trace:module:map_image mapping section .rsrc at 0x41b000 off 15a00 size a400 flags 40000040 trace:module:load_library loaded ntdll.dll 0x403512c4 40050000 ------------------------------------------ mailto:Mike_McCormack(a)looksmart.com.au ph +82 16 430 0425 __________________________________________________________________ Get your free Australian email account at http://www.Looksmart.com.au

[Problem report] X11DRV_ScrollWindowEx
by Gerard Patel June 10, 2001

June 10, 2001

This function hangs with the following apps (at least) - Notepad Win 3.11 - Notepad NT 4 - Eudora 1.5 In all cases, the problem appears when a text has several pages and I try to scroll toward the beginning of text. The problem disappears if I comment out the calls to X11DRV_StartGraphicsExposure and X11DRV_EndGraphicsExposure. The apps seem to work just as well. The hanging occurs because there is no X event generated in X11DRV_EndGraphicsExposure. I don't quite see why there should be one in this case. Gerard

FYI: ControlSpy has stopped working
by Guy L. Albertelli June 10, 2001

June 10, 2001

Using the current CVS (6/9), certain ControlSpy modules (REBAR and COMBOBOXEX) no longer seem to work, even with the native versions of COMCTL32. The internal child windows in the left pane are no longer drawn. Seems to have occured sometime since 6/1. I will look into it tomorrow after some rest. Strange.

In this case it's clear that it makes more sense to emulate the NT behavior, since this is what is documented. Of course we could do a winver check, but if we do this for every single difference between Win98 and NT, we'll end up with a mess of spaghetti code with more version checks than actual code. So winver checks must be limited to cases where they are demonstrably necessary for a real-world application. -- Alexandre Julliard julliard(a)winehq.com

We can't start breaking things based only on your suspicion that someone somewhere will have used a feature that isn't documented at all (plus there is a documented way of doing exactly the same thing).

Question about the new window design
by Gerard Patel June 6, 2001

June 6, 2001

Since the patch of 4 June, all windows are created as X windows. This makes one of my test apps to crash; it's creating a child window in the WM_NCCREATE event handling of a window. When the child window is created, X bombs because the X window parent does not exist yet - Wine is trying to call XCreateWindow with parent = 0. What is the best way of fixing this ? Gerard

The ram isn't actually used, it's only reserved from the address space with an anonymous mapping.

I fully agree with him. However regardless of this, uname shouldn't be used (at least not directly). Autoconf provides a standard way to do this (which BTW happends to use uname). It can be used as below. AC_CANONICAL_HOST case $host_os in *cygwin* ) CYGWIN=yes;; * ) CYGWIN=no;; esac It requires two files config.sub and config.guess be distribute along with Wine but that is not really a problem. Perhaps we need to do this anyway. Autoconf 2.50 has discontinued AC_CYGWIN so CYGWIN support seems to require it regardless. Actually the code above is how this is done with Autoconf 2.50. However making CYGWIN an exception is one thing, doing it in other cases is quite another thing. IMHO you will need to provide a _really_ convincing argument that we should make another exception assuming of course we make the first one for CYGWIN which we haven't done yet either.
