Any advice on how to debug this?
by Medland, Bill 12 Jul '02

12 Jul '02

Any suggestions would be appreciated. The application runs reasonably with builtin comctl32/commctrl but there are some alignment issues which I suspect might be corrected by using the native one. However when I try running with native ones I get two debug consoles and the application continues. (Not a problem). Basically the main program starts two other programs as OLE servers and they load and init commctl32.dll. The stack traces in both cases are similar and indicate to me that the processes have ended up executing data. However by the time I get to disassemble the code referred to by the backtrace the code isn't there any longer. What's my best bet for tracking this down? I've tried winedbg with as many BreakOn.. set as possible but the processes seem to disappear from under the winedbg processes Bill

HEADER order and index issue
by Medland, Bill 11 Jul '02

11 Jul '02

Dear all Before I spend days trying to find out, can someone tell me straight off? There is a problem with the comctl32 header control and I want to know which is the correct solution. The result is that columns af the associated list control are sometimes put in the wrong place. Here's why! It is a known issue that the first column of a listctrl is left-justified. Therefore the Microsoft-accepted way to proceded with the list control is to add a blank left column, add the columns after that with whatever justification is desired and then delete the first column. Assume we aren't doing any clever column reordering. As the columns are added their headers' orders are equal to the indices. But then the first is removed. When we get to HEADER_Refresh it goes to display them in the correct order; good. However there is an implicit assumption in the code that given n columns the orders there will be one column with order 0, one with 1, ... one with n-1. So 1. Is that assumption invalid? If so then I'll change the code to display the columns in the specified order, assuming that the orders may not be sequential. 2. Is that assumption valid? If so then I'll change it so that deleting a column will modify the orders of the remaining ones. Bill

I wouldnt recommend this as ReactOS will be adopting some of the wine/programs including help.

Bad exe
by admiral coeyman 11 Jul '02

11 Jul '02

Group, While running tests at my end, I found an odd problem that seems to have developed out of the blue. It seems that only 32 bit dos executables will now run on my system. All of the 16-bit executables that I've been using for the past few years generate 'bad exe' errors. I've redownloaded most of the tree and nothing has fixed this problem. Before I look too deep, is this a problem that anybody else has? It's possible that my local tree has been damaged or that my development tools are not right. God Bless, --Robert 'Admiral' Coeyman [I've had vga planets 4.0 running.] -- --- May you live as long as you wish and age but a single day. http://www.dotguy.net/ admiral(a)corner.net Webmaster/ Linux Administrator Computer Co-Op/CornerNet

Please look here where I explain a problem about this: http://www.winehq.com/hypermail/wine-bugs/2002/06/0422.html Basically I said, sometimes opengl apps minimizes when other windows (like a messagebox) become active, and after restoring the opengl window, it produces no output. Here is another interesting note: some people have the same trouble with the movies on real windows like we do on wine. I suggested to rename the movies folder to them, and guess what it worked!

Is there a way to set the font used by winedbg? The font that it is using on my machine is too small with the monitor resolution set at 1600x1200 (which I want to keep). I'd like to bump the size up a few points... Thanks for the help, Carl

RFC: Re: [ros-kernel] Shell32 and dplax
by Steven Edwards 10 Jul '02

10 Jul '02

Note: Forwarded to wine-devel I'm more in support of us chaning wine rather then adapting win9x calls to ReactOS. That being said I have enough trouble writing a 3 line patch so my voice doesnt count to much..."You guys are the programmers, I just break shit." IMHO the way WINE handles certain things is really fubar. A good example besides MapSL and ConvertToGlobalHandle is the way WINE implements PSAPI. All wine psapi does it convert the toolhelp functions already implemented in to the needed format with a wineserver call or two thrown in. If we are going to use wine and not fork the crap out of it then we should fix the 9xisms as we find them. Currently wine has all sorts of ways for doing things, you have win16 apis being called in some places, ntdll in others and then 9xisms all over the place. So far we have MapSL ConvertToGlobalHandle PSAPI DriectX HAL interfaces ? idunno I guess it comes to what can we do to better share code. Currently there is not a chance in hell of us sharing PSAPI in its current state. I started two bugs in wines bugzilla a few weeks ago regarding it. Mabey we should have a meta-bug for making WINE more NT like in "certain" areas. I dont expect the wine projects to make all sorts of changes just for us and not as they are trying to get a 1.0 release. Anyone got any feedback? Mabey we will get more support for this once David and Jason are done with the basic Windowing.

So now what do we do. Having messed about, got a repeatable case and generally bashed my head around I have got to the following unfortunate situation. It looks to me like: comctl32.dll includes a shared data segment. One of the entries in that segment, presumably during the DllEntry, is populated with the address of GetSystemMetrics A second copy of comctl32 then tries to use that address to call GetSystemMetrics Unfortunately the second process has user32 mapped somewhere else and so the call goes somewhere weird and things fall over. Any ideas as to what we can do about it? Bill

Meta-bug conversions
by Francois Gouget 10 Jul '02

10 Jul '02

Hi, I propose to use what would hopefully be better concepts to replace the following meta-bugs: * bug 35 - Wine 0.9.0 Meta Bug http://bugs.winehq.com/showdependencytree.cgi?id=35 Instead we could tag all the bug that should be fixed in Wine 0.9.0 with the 0.9.0 target milestone. * bug 395 - Tasklist http://bugs.winehq.com/showdependencytree.cgi?id=395 * bug 455 - FIXMEs http://bugs.winehq.com/showdependencytree.cgi?id=455 * bug 406- Tasklets http://bugs.winehq.com/showdependencytree.cgi?id=406 These three could be replaced by keywords: Tasklist, FIXMEs and Tasklets. Then these bugs can be replaced with a query that returns the bugs that have these keywords. In all cases, the advantages of the alternative methods are: * the above meta-bugs introduce artificial dependencies between bugs * each time a bug changes status, you get an email for the bug, and an email for the corresponding meta-bug * similarly, moving a bug moving from one category to another generates three emails * the new concepts seem a better match Does the above proposal look ok? If so then, once the required keywords are created, I can tag the relevant bugs and retire the meta-bugs (which will create a flurry of emails to wine-bugs in the short term). -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ I haven't lost my mind, it's backed up on tape around here somewhere...

about XIM support on wine
by rain shaw 10 Jul '02

10 Jul '02

Hi all, I do apply some patches to the wine source according to some tips in bugs library,and I can input chinese in notepad now. But,every time window was created,will the input method popup.For example,if a message box popped up,the xim will popup as well. It seems that we called the XIM related Xlib function every time new window was created. Would u please give me some suggestions about how to disable create and open XIM while create non-text-input related window? in other word,how to determin the x-window that going to be created is a control that need input method ? Thanx!

Debugger
by Massimo 10 Jul '02

10 Jul '02

Hmmm.... I fiddled a bit with winedbg and found it awful to use.... Maybe I'm too comfortable with visual debuggers :-) There's no plan to make a graphical front-end to it, for example extending DDD or better GVD ? I had a look at GVD sources and docs, and it shouldn't be too difficult to add a supported debugger... It has a quite good support for many external debuggers.... I see only une problem on it, as it seems to me that winedbg opens a new xterm and translates his i/o on it, which can confuse GVD as stated in docs. So, 2 questions : 1) - There's a way to instruct winedbg to not change xterm ? 2) - There's a volunteer with enough skills on winedbg that can help me to write GVD patch ? :-) Regards Max

PSDRV question
by Carl Sopchak 10 Jul '02

10 Jul '02

I've been trying to get Quicken 2000 Deluxe running in wine. After I figured out that it wasn't finding a DLL for the internet connection (and got that fixed), I started testing the second-most important function of Quicken that I need: check printing. All went well until I tried to print a sample check (to verify alignment), at which point Wine crashed into winedbg. I figured out why: When reading the ppd file, it sets up an *InputSlot for ManualFeed (even though it's not really an InputSlot, but most Win programs treat it as one...). The problem was that, in ppd.c, a Name wasn't given to the slot (but a FullName was), so when ps.c tried to output the header for the InputSlot it crashed (since strlen(NULL) causes a crash). I hacked the AddSlot call to name the slot "Manual", and this seems to work OK. The question that I have is, is this the way that it should REALLY get fixed (does the name matter?), or should something else be done? I'd be happy to correct my hack, if necessary. In either case, I can post the patch to sourceforge, once I know "the right way" this should be handled. Thanks for the help, Carl P.S., I added some TRACE() statements to help me debug this. These can be left in the patch that I post, right?

No X11 input events in DGA2 mode
by Andy MacLean 10 Jul '02

10 Jul '02

I was trying to run Starcraft under wine in using the X11 DGA2 mode to get a decent frame rate. I tried running it under various versions of wine and got the same result every time. The problem is that when wine runs the game using DGA2 it ignores all input from the keyboard and mouse and so appears to hang. When running the game with DGA2 support disabled (i.e. not running as root) everything works fine but I get a much lower frame rate. I'm new to wine but I had a stab at fixing the problem which as far as I can see is the following: -> wine creates one X11 display connection for each thread and one 'global' display connection to use for various things like DGA2 which it puts in the 'gdi_display' global variable. The thread specific connections get put in x11drv_thread_data structure pointed to by the driver_data pointer in each thread's thread specific structure. -> wine then switches to DGA2 mode if it can and does an 'XSelectInput' to turn on DGA2 input events. It switches to DGA2 mode using the gdi_display connection so all input events will now come through this connection. -> at some point something asks for new X11 events. It goes into the 'X11DRV_MsgWaitForMultipleObjectsEx' function to poll the X11 display connections for each thread. This ends up calling the 'process_events' function in dlls/x11drv/event.c with the 'x11drv_thread_data' structure for each thread. This is the only function that calls 'process_events', which is the only place that calls any X11 event fetching function outside of 'wineclipserv.c' and 'clipping.c' (which seem do something irrelevant to the dga2 problem). -> but process_events can only look at the thread specific X11 display connections since this is the data it gets passed. I cannot find any code which sets up an 'x11drv_thread_data' structure for gdi_display and XNextEvent is only ever called from inside process_events on data->display. Therefore we never poll gdi_display for X11 events at all so I never get any input. I tested this with some debug output code and wine deffinitely never polls gdi_display for events at any time while running the game. X11DRV_MsgWaitForMultipleObjectsEx explicitly does an XFlush on gdi_display as though it is expecting to have to poll it separately, but it never does ... I tried changing 'process_events' in dlls/x11drv/events.c to the following: static int process_events( struct x11drv_thread_data *data ) { XEvent event; int count = 0; wine_tsx11_lock(); while ( XPending( data->display ) ) { XNextEvent( data->display, &event ); wine_tsx11_unlock(); EVENT_ProcessEvent( &event ); count++; wine_tsx11_lock(); } #ifdef FIX_DGA2_INPUT while ( DGAUsed && gdi_display != NULL && data->display != gdi_display && XPending( gdi_display ) ) { XNextEvent( gdi_display, &event ); wine_tsx11_unlock(); EVENT_ProcessEvent( &event ); count++; wine_tsx11_lock(); } #endif wine_tsx11_unlock(); return count; } And this fixed the problem. What's bugging me though is that if this is the correct answer then how do any programs work at all in DGA2 mode? Wouldn't any program hang in the same way as soon as wine switched to DGA2 mode? It would be handy if this were fixed in the wine code so I don't have to keep downloading source and patching so can someone who knows more about the code please let me know if they think this is worth submitting as a patch or point me in the right direction if this is on the wrong track? Thanks in advance, A.

(BTW HTML email is generally sort of frowned on here) Unix doesn't run windows programs. I suggest you actually read some of the documentation at www.winehq.com <http://www.winehq.com> , especially the Winelib stuff. Basically wine is a Unix program that understands the structure of Windows DLLS and exes. Wine itself runs, loads the dlls and exes into memory and executes them. Some DLLS are replaced by plug-compatible unix so's that interface to the lower levels. So CreateBitmap will eventually result in calls into probably X11 code.

How does the Winodws program run in Unix. For example, i write a program where i call the CreateBitmap() method, what happens. How is a dll called in the unix environment. From what i know, unix dlls are .so files. From the wingdi.h file in the wine\include directory, how does the unix OS know how to resolve the WINAPI call. If i am right, windows dll's are implemented in unix, how is this done. I'm kinda flustered at the moment, would appreciate the help Thanks, Preetham.

Known issue. The debugger doesn't yet know how to handle the extended information available about C++ classes. (If it really cheeses you I have a patch that basically replaces the detailed garbage with "we don't understand") Bill
