Does Windows have one of these?
by Bill Medland 25 Jan '02

25 Jan '02

As I look deeper into the DrawText boundary behaviour it becomes clear to me that the Microsoft version must actually keep the & symbols in the string until the very last moment. In particular it looks to me like they actually measure strings that contain them. I can't see how they can do that with GetTextExtent and its relatives; I can't see where to hide a flag as to whether to interpret the & or not. Does anyone know if there are Microsoft undocumented functions or undocumented ways to measure and output a text that includes & symbols with a way of specifying whether they count as prefix characters or not? Personally it seems silly to me and I don't intend doing so myself unless there is a good reason to duplicate all of Microsoft's weird bugs. Bill

I am currently working on DrawText which should provide everything needed to draw the text properly. I am feeding it to Alexandre in small pieces so that we don't break anything. Microsoft, as far as I can see, don't actually use DrawText; they appear to reimplement all the ellipsification but I don't see why.

Excessive clipping of text in listview
by Bill Medland 25 Jan '02

25 Jan '02

Does anyone know how we (again) broke the text in the large icon display of listview? It seems to come and go as we develop. The symptom. Our application has a ListView window. As of yesterday's cvs most of the text only displays about 2 or 3 pixels wide, while a few are readable. I am just backtracking but I'm in a rush (I have to put together a demo machine by yesterday) and I'd like to know how far back to go. Bill

C++ Winelib problems
by Peter Hunnisett 25 Jan '02

25 Jan '02

Hello all, I've been tooling around with building a C++ application using Winelib and I've come across a couple of problems resulting from the use of global constructors. The problems can be reproduced with a simple C++ application which from a constructor calls a method which is resolved through a dll import. 1) If this program is the main program, wine_dll_set_callback has not yet been invoked so the __wine_dll_register call doesn't resolve the import list. The problem is that the constructors of the program are run immediately after the dll is registered which results in calling a non resolved import. This can be worked around by simply creating a non C++ stub which does a LoadLibrary/GetProcAddress on the real main exe. However I'm wondering if there is a good reason for needing to wait until after the main exe is loaded before being able to resolve imports? I must be missing something from my quick view of the code. 2) The order of running constructor execution and DLL entry point is incorrect. To show the problem assume you have foo.dll which imports bar.dll Present order for builtins: Load foo.dll Start to resolve foo.dll dependencies Start to resolve bar.dll dependencies Finsh resolving bar.dll dependencies Run bar.dll C++ constructors Finish resolving foo.dll dependencies Run foo.dll C++ constructors Run bar.dll DLL entry point Run foo.dll DLL entry point I actually haven't checked if PE images presently have the same problem since I don't know what triggers the ctor execution for a PE image. I assume that it's the running of the DLL entry point, but I don't know for sure. Hopefully I'll find the time at some point this week to whip up a test. The correct order: Load foo.dll Start to resolve foo.dll dependencies Start to resolve bar.dll dependencies Finsh resolving bar.dll dependencies Run bar.dll C++ constructors Run bar.dll DLL entry point Finish resolving foo.dll dependencies Run foo.dll C++ constructors Run foo.dll DLL entry point The problem seems reasonably simple enough to resolve but I'm sure that I'm missing something since my patch doesn't work for the present version of wine :(. I think that the problem is that there's an issue with inter DLL dependencies somewhere as it dies in SYSMETRICS_Init with a bad hdc. I've attached a patch which removes the recursive dep search from MODULE_DllProcessAttach and moves MODULE_DllProcessAttach from LoadLibraryExA into MODULE_LoadLibraryExA. Does this seem like a reasonable approach to take? Any problems with the patch? Ciao, Peter

C testing framework. ASCII/Unicode portable version
by Andriy Palamarchuk 24 Jan '02

24 Jan '02

Attached version of the C testing framework, which is implemented with using TCHAR.H macros, so it is portable between ASCII and Unicode platforms. Also implemented test which can be used to test ASCII and Unicode API. As I found out creating ASCII/Unicode portable code requires much more attention than creating plain ASCII-only code, probably the same level of difficulty as creation Unicode-only code.

Privaleged instruction
by Nog 23 Jan '02

23 Jan '02

Hi, Just for the fun of it I tried to run the dos installer of Mechwarrior 2: Mercenaries. It didn't get too far as the installer crashed on an unhandeled Privileged instruction. According to winedbg the instruction is 0x0002:0x10000 push %cs. To see what the opcode of this instruction might be, I added a trace to the INSTR_EmulateInstruction. Looking at the trace I found that the instruction it was having to emulate was 0x00 which looks very wrong to me. But just to check I simply made that function return true if the instruction was 0x00 but this only seemed to make things worse, the exception still occured but the debugger didn't launch. What I would like to know is, is push %cs realy a Privileged instruction (which I think it might be)? Looking into why INSTR_EmulateInstruction doesn't get the right pointer, the offset looked too big to me. Shouldn't it roll over to the next segment after 0xffff? The problem with the way that it is now is that the following macro, which converts the segment offset pair to linear addresses cuts off the upper bits, which looks correct. #define PTR_REAL_TO_LIN(seg,off) \ ((void*)(((unsigned int)(seg) << 4) + LOWORD(off))) What I want to know is why the offset is so high? nog.

Of course it shouldn't require it. It should simply skip parts of the test if the native version is not available. if(&wine::is_native("wininet")) { # Do native wininet tests } > Choosing to use a native dll is more up to the developper > to debug a > test.

Well it allows us to automatically test a non-developer Windows installation directly under Linux without requiring him to reboot. Even developers make find it useful to quickly be able to modify the loadorder without having to modify his configuration. Sometimes what you want to test is quite subtle, like you have a function A in module B that calls function C in module D. Perhaps you want to test the robustness of Wines implementation of function A by testing it both with the native and the builtin version of D. If you have many such tests it would be a lot of unnessary manual work to switch D between native and builtin while testing B as builtin. Then perhaps somebody else have some use I haven't even though of. The main use will be I think to force tests to as the default test the builtin version since if you type "make test" in a directory you really expect to test the files in THAT directory, not the native version even if your ~/.wine/config specifies that.

We cannot ship native dlls with Wine for obvious reasons, so requiring the native dll would force Wine developpers to have a Windows partition installation around, and one configured for use in the tests. Otherwise they would not be able to run the tests, would they? I don't think that's good. Choosing to use a native dll is more up to the developper to debug a test. And then modifying the configuration file, as we usually do to debug applications, should be simple and familiar enough.

Open Letter to DOJ re Microsoft Settlement
by Dan Kegel 22 Jan '02

22 Jan '02

The proposed settlement in the Microsoft antitrust trial will probably be accepted by the judge unless a lot of people complain soon, even though it lacks any useful enforcement provisions and fails to prohibit many of Microsoft's anticompetitive practices. I've drafted an open letter to the Department of Justice to explain why the proposed settlement should not be accepted; it's at http://www.kegel.com/remedy/letter.html I'd be honored if you would read it, and consider signing it with me, or submitting your own comment to the DOJ. Either way, the federal deadline for public comment is Monday the 28th.

sparc solaris build
by Srdjan Matovina -- Customer Engineering 22 Jan '02

22 Jan '02

Hi, I've built wine-20011226 on sparc with the only one issue left open: The resource compiler wrc core dumps when hit the bitmap (BINRES) part of .rc file. There is an alignment problem inside convert_bitmap() in newstruc.c file. The alignment problem came out from BITMAPINFOHEADER struct. But this was just the beginning! I've commented out body of convert_bitmap() just to see what will happen when run libtest/hello test case. After running wineserver, the libtest/hello core with the same problem: Program terminated by signal BUS (invalid address alignment). This time at different place: RtlSecondsSince1970ToTime from ntdll.so (time.c) struct FILETIME. Obviously I'll have an alignment problem with every structure in general. Is there any guideline for this kind of problem? Thanks Srdjan

Many thanks for generating them, anyway. >From a first glance, it seems that the app doesn't do overlapped recv(). (lpOverlapped & completion_func are always NULL), so there should actually be no difference (well I'm now using recvmsg() instead of recv(), and the overhead for 16 bit Winsock apps is definitely larger, but I cannot see why that should slow everything down that much). Perhaps I screwed up the blocking semantics of non-overlapped IO. Have you generated the traces under exactly the same conditions? Can you explain what exactly you did? Martin

Some musings about DGA2 support in Wine...
by Lionel Ulmer 21 Jan '02

21 Jan '02

Hi all, After being prodded by people on #WineHQ to look at the current DGA2 problem in Wine (it it works fine for graphics, but does not accept any user input at all and needs to either kill Wine remotely or do the three finger salute to the X server), I found the following things : - the DGA2 code (in dlls/x11drv/dga2.c) used the gdi_display connection to open the framebuffer and setting-up all the input handling. But it was the thread->display connection that was used to process the events. This is a no-go as when DGA2 is entered, there is only one connection that receives the event, the one which has grabbed the frame buffer (thanks to Ove to remind me of the 'one connection per thread' thingy). - so I removed all the mentions to 'gdi_display' in dga2.c and replaced them by the current thread display and still no go (although I checked that the event processing in WaitForMultipleEvents and subsequent process_events was done on the correct display). Still no go. So I investigated a bit with a little test program : = I did first try setting up DGA2 in a separate display and then doing all the 'standard' processing on another display (that is Wine does with DGA2 set-up in the init function to test if DGA2 is available and then really use it in another thread). As my test application still was working fine, this was not the problem... = then, I saw in the logs some calls to X11DRV functions after we have entered DGA2 (some due to the DDraw stuff creating DIB sections and so on, some due to the application I think). After adding the same stuff in my test program (ie I created a window just after entering DGA2), I found that it perturbed the event processing (I still had motion events, but neither key presses nor button presses). - so, finally, just to try, I backed off my changes in dga2.c (ie I used again the gdi_display for all the set-up) and had the process_events function in windows/x11drv/event.c use gdi_display instead of data->display when DGA was used (by testing the DGAUsed variable). And now it seems to work just fine.... All this leads now to the 10 � (an Euro sign for all the people not having an iso8859-15 font :-) ) question : how to fix this 'properly' and not with the hack I just did ? The only somewhat 'clean' solution I found would be to create a display connection specifically used for DGA2 (thus we would be sure that no X calls would 'pollute' the link). And in process_events, if DGA2 is used, use this connection instead of the thread connection (we already have some DGA specific variables there, what would be one more :-)) ). After, the question would be how we are sure that it's the 'good' WaitForMultipleEvents that receives the events (if the application is multi-threaded and has multiple threads calling this function). Anyway, if people want just to play some games using DGA2, they can always use my hacky solutions I just described up there :-) Lionel -- Lionel Ulmer - http://www.bbrox.org/

I did a little research and found in a few places information that UNICODE is used by Windows headers, _UNICODE is used by C-runtime/MFC headers. However I did not find official explanation of this. Some examples, including a few MSDN ones, define both. E.g. see: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wss/wss/_e… Can you tell now where we need to use which one?

Why did you add an exception handler? Do you have an app that passes garbage pointers to GetPrivateProfileInt? -- Alexandre Julliard julliard(a)winehq.com
