Problem with Quicken crashing: Help, please!
by Carl Sopchak Feb. 8, 2004

Feb. 8, 2004

Hi, Since about mid-December, I've had an issue running Quicken 2000 Deluxe using the CVS version of wine. The symptom is that *sometimes* (I hate that word when trying to debug!) the program crashes when printing a partial page of checks (landscape, centered, 1 or 2 checks on the page, not 3). When it happens (mostly when I'm trying to print real checks, not when I'm trying to debug the problem - argh!), it always happens after Quicken asks if the bottom tear-off part of the page of checks is still attached, and I click the Yes button. The actual error that I get is an X error, stating that X has run out of resources. The reason for that is that it's trying to create a bitmap with dimensions 1,075,900,608 by 1,082,644,840. Of course it's gonna run out of resources! Running it with --debugmsg, I see that this size is being passed to either CreateBitmap() or CreateCompatibleBitmap() in several places. I have added TRACE() statements before every call to either of these two functions that I can find in the wine source, displaying the values. Unfortunately, I don't see my trace statements in the log (created by redirecting wine's output with --debugmsg +all,-snoop,-win32,-heap) before the "bad values". (I DO see the statements for other calls, as well as those I put within CreateBitmap, so they are getting compiled, etc., correctly...) I have spent a few days - on several occasions - trying to debug this, but I keep running into a brick wall. Before I go much further here, I gotta say that besides other debugging of wine that I've done in the past, I know little to nothing about the Windows API, or the internals of wine. I can't call myself a C expert, either. (I have been a computer consultant for 20+ years - just on other platforms - so I consider myself competant in general debugging and various languages. Picking up C, so far, hasn't been that big of a deal. But I certainly don't know many of the nuances!) That said, here are the questions that I'm hoping someone can help me with so I can continue the debugging process: 1) I'd LOVE to use --debugmsg +snoop, but when I do this, the text box Quicken displays (within the Print Checks dialog) for the user to enter the first check number to print does not get displayed, and the program gives an "invalid check number" error, and I never get to the point that the program crashes. So, as an alternative to tracking down and trying to fix this debugging bug (which I really don't have the expertise [or, frankly, desire] to do in a reasonable amount of time), I was wondering if there was a data structure available that I could use in relay.c that would get me the CALLING procedure name, so that I could add the DPRINTF statements to show who called CreateBitmap / CreateCompatibleBitmap with the "bad values". Any help - as specific as possible - would be greatly appreciated... (Trying to follow all of the calls and returns gets pretty confusing pretty fast!) Or, if anyone has a clue on why +snoop would cause the textbox problem... 2) Now, for my lack of C knowledge: When adding the TRACE() statements, I found several places where the width and height parameters being passed to CreateBitmap and/or CreateCompatibleBitmap and/or CreateDIBitmap were not INT. For example (approximate line numbers in []) dlls/conctl32/animate.c[224], listview.c[4051], trackbar.c[799], treeview.c[4004], objects/dib.c[183], and metafile.c[1037] all pass LONG's, and dib.c[825] passes width as a DWORD, and height as an int. (This seems to be a potential issue relating to the function DIB_GetBitmapInfo, as the width an height fields of the data structures passed in as *header are LONG, except if *header is of type BITMAPCOREHEADER, where it's WORD, but they are being passed back to DWORD and int pointers.) Does the C compiler do an implicit conversion of these data types to INT (correctly), or is the fact that parameters are too big suspect in causing my problem? Can I just assign a LONG (and DWORD) to an INT (i.e., iWidth = lWidth) to do the conversion? Hopefully, these are simple enough questions for someone with the knowledge to answer and get me back on track to solving this issue. Any and all help will be greatly appreciated! Thanks, Carl P.S., I think my next step is going to restore my wine source tree from my November (October?) backup, and make sure the issue is in fact something that's changed in wine, and not some configuration change that's happened. (Althought I'm not certain of the timing, in the same time frame, I've attempted to install IE6, installed TaxCut 2003 (which required IE6 dlls, and seems to run, BTW. I haven't done my taxes yet, though...), and played with fonts some.

manpage slimmed down?
by cedric Feb. 8, 2004

Feb. 8, 2004

Hi, recently i upgraded from 20031118 to 20040121. I noticed a lot of bugfixes and speed increases. Thanks! However, i don't like the new man.1 page as much as i did the one from 20031118. The section about what debug channels wine has is gone. This was nice info to have under 'man wine'. Why is it removed? Regards, cedric P.S.

IE6 Security Controls/URLMon;msimtf (nhl 2004)
by Abdul-Haseeb Ahmad Feb. 7, 2004

Feb. 7, 2004

Okay when i use IE6 (installed by mike's script) any webpage that uses an activex control says my security settings are too high, even if i lower them (both custom settings and the slider have no effect), or even if i make the site a trusted website... now i believe this might be what be causing problems with NHL2004 because i get a script error 80040154 (which doesnt let me go in game) when i go to the game setup screen(rest of the game is flawless other than DXImageTransform filters not functioning), which is caused by a missing CLSID entry.. so i checked out the errors I was getting and urlmon.dll wasn't registered and neither was msimtf... now the thing that nhl was trying to call was the security manager which is part of urlmon.dll.. when i registered urlmon, it would crash the game, and i can't get msimtf to register because of problems it has with advapi32/user32 implementations... Im not sure what msimtf does, but i have a hunch that clearing the urlmon issue might solve my problems.. anyone have an idea of what i can do to solve this issue? Theres also an error: fixme:system:SystemParametersInfoA Unknown action: 8198 I have a feeling this is harmless though...

Feb. 7, 2004

Hello everybody. I'm new to the developers list. I have a question about patches in bugzilla. Do developers usually read the bug reports to check for patches? Or is it better to send them directly to wine-patches? I'm talking about the following (minor) bugs, just in case: http://bugs.winehq.org/show_bug.cgi?id=1980 http://bugs.winehq.org/show_bug.cgi?id=1981 Thanks in advance. -- Leonardo Quijano Vincenzi <lquijano(a)hotpop.com>

Update: starcraft runs faster from debugger!
by cedric Feb. 7, 2004

Feb. 7, 2004

crossposted to wine-dev, and wine-users Hi, I've done some more tests, and i found that when i run winedbg starcraft and wine starcraft and then again winedbg starcraft etc. It works, but always following this pattern: <boot my box> winedbg starcraft :all runs perfectly wine starcraft: all video choppy winedbg starcraft :all runs perfectly winedbg starcraft: all video choppy wine starcraft all video choppy winedbg starcraft: :all runs perfectly Looks like winedbg leaves some things in a bad state, and running wine seems to solve the problems. However, after each run of winedbg i have 4 more of these: 1797 pts/0 00:00:01 wine-kthread <defunct> And after about 4 or 5 times trying the wine trick doesn't work anymore, Whatever i do the game starts choppy. I don't know how to trace a program while it's running from the debugger, winededbg --debugmsg +x11drv <prog> doesn't seem to work. How is the corrrect startline? The trace from wine shows that DGA is disabled (even with /dev/mem set at 777) Can somebody confirm this pattern of events? you need ,wine-20040121 (haven't tried other versions) and starcraft retail or starcraft shareware to reproduce this.

programs/winedbg/elf.c breaks non-Linux platforms
by Gerald Pfeifer Feb. 7, 2004

Feb. 7, 2004

Hi, I'm afraid the following patch which added programs/winedbg/elf.c date: 2004/02/03 00:14:12; author: julliard; state: Exp; Eric Pouech <pouech-eric(a)wanadoo.fr> - now detecting Dwarf debug information in ELF modules (but don't load it) - separated module management (pe.c, elf.c) from debug information management (stabs.c, msc.c) - worked around new wine-pthread and wine-kthread loaders (no longer use "wine" as default loader) - better convergence of gdb-proxy and winedbg for ELF handling - fixed ELF link-map walking - now using all loaded shared libs - (with the help of Robert Shearman) - added a bit of const correctness breaks building Wine on non-Linux platforms. For example, on FreeBSD 4.9 I'm seeing: elf.c: In function `DEBUG_ProcessElfFile': elf.c:344: error: `DT_NUM' undeclared (first use in this function) elf.c:344: error: (Each undeclared identifier is reported only once elf.c:344: error: for each function it appears in.) elf.c:344: error: `DT_PROCNUM' undeclared (first use in this function) elf.c:344: error: `DT_EXTRANUM' undeclared (first use in this function) elf.c:345: error: `DT_LOOS' undeclared (first use in this function) elf.c:345: error: `DT_HIOS' undeclared (first use in this function) elf.c:346: error: `DT_LOPROC' undeclared (first use in this function) elf.c:346: error: `DT_HIPROC' undeclared (first use in this function) Gerald -- Gerald Pfeifer (Jerry) gerald(a)pfeifer.com http://www.pfeifer.com/gerald/

Wineboot should process RunOnceEx Entries
by Geoffrey Antos Feb. 7, 2004

Feb. 7, 2004

I saw early postings about RunOnceEx in this mailing list circa January 2003, however the problems they presented were never fixed. Some programs come with simple INF installers because people can cheaply create an INF file, and use a free Setup.exe bootstrap file that reads the name of an INF file from Setup.ini or something similar. These programs do not have any way of processing RunOnceEx themselves. In the distant past before I had converted to Linux and wine, I used to deal with such programs quite a bit; RunOnceEx was Microsoft's way of allowing simple installers to register files, especially if a reboot and wininit was necessary to overwrite files. The basic structure of the registry format is: [Software\\Microsoft\\Windows\\CurrentVersion\\RunOnceEx\\Number] "Number"="program.exe arguments" "Number"="c:\\somepath\\somedll.dll|SomeExportedFunction" Number is nothing more than a number. All commands are processed in sequential order, first by key, then by value. If there is no pipe symbol in the line ('|'), the data of the value is executed as a program, with all following tokens passed on as arguments. However, if the pipe symbol is included, the portion to the left is treated as a DLL, and calls the exported function of the name to the right of the symbol. Once all values in a key are processed, the key is deleted, and the process starts with the next key. There is one subkey that has a special meaning: All keys/values in [Software\\Microsoft\\Windows\\CurrentVersion\\RunOnceEx\\Setup] are not processed at boot-up. Rather, they are read by the program runonce.exe, not included in wine. It is through this key that one gets the annoying "Updating Windows" box in the upper left corner of the screen, listing tasks being performed. I believe Powertoys for Windows 98 utilized this feature, but I do not remember how. However, these days RunOnceEx still has one important feature: Some people, like me, have programs that fail to load objects because the OS version is not set to XP. When the OS is set to xp, the install-ie6 script does not automatically process the RunOnceEx keys, failling to register all of the DLL's, including the Crypto support needed for programs such as Steam. As such, for IE6 alone, users have to process 50+ lines by hand, in something that SHOULD be processed at bootup, via wineboot.

Re: PATCH: virtual fixes for native mode
by Juan Lang Feb. 7, 2004

Feb. 7, 2004

Hi Uwe, in NT the native (system call) interface is through ntdll. There are a number of subsystems implemented on top of that: the win32 subsystem, the posix subsystem, and the OS/2 subsystem. It's possible however to write an app that just uses ntdll; this is a "native" NT app. This page has a pretty good explanation: http://www.sysinternals.com/ntw2k/info/native.shtml --Juan __________________________________ Do you Yahoo!?

That's the point, it doesn't work on wine in the current state. That's why I try to fix wine. Use my patch (even if it's wrong for your progs) then my app should come up and you can test what's going on. This bug in wine prevents many VB apps from running on wine.

Wrong short filenames instead of long ones
by Fabian Cenedese Feb. 6, 2004

Feb. 6, 2004

Hi I'm trying to find a file copy tool which works on windows as well as wine. I tried several and this looked promising: ftp://ftp.simtel.net/pub/simtelnet/msdos/fileutil/cc108dos.zip On Windows it copied all files without problems and kept the long filenames even if the name implies that it's DOS-only, but it worked fine on W2K. But on wine the long names where all shortened to something like CINO~E2H.CPP. So it doesn't look like normal DOS short names ...~1.cpp but it's not the long name either. Can anybody try this out? My wine (actual cvs) config is set to windows version nt40. Thanks bye Fabi

32bpp bitmaps
by Kevin Koltzau Feb. 6, 2004

Feb. 6, 2004

I am loading a 32bpp bitmap from resources of a dll, but under wine its being reported as 24 bit..for example void main() { HMODULE hTheme = LoadLibrary("C:\\Windows\\Resources\\Themes\\Luna\\Luna.msstyles"); HBITMAP hBmp = LoadBitmap(hTheme, "BLUE_BUTTON_BMP"); BITMAP bmp; GetObject(hBmp, sizeof(bmp), &bmp); printf("bpp=%d\n", bmp.bmBitsPizel); } under Windows prints 32, under Wine prints 24 I've tried to find the cause of this, but much of this is deep in x11drv which I am not familliar with at all.. Is wine stripping the alpha channel for some reason? or is this a bug? (I've only run this example on that one file, its the native Luna.msstyles theme from an XP system)

App compiled with Delphi5 works, same App with Delphi7 does not.

Dear Newsgroup, I have downloaded and installed Release 20040121. I have a very small application (for testing purpose) which I can compile with Delphi 5,Delphi 6,Delphi 7. The application compiled with Delphi5 works fine. The same application compiled with Delphi7 shows an exception <EAccessvioalation in Module zxtheme.dll at 00006A71>. Any hints what to do ? Thank you, Samuel Herzog

Investigating the XInitThreads deadlock bug
by Sami Aario Feb. 5, 2004

Feb. 5, 2004

Hi all, I decided to investigate this old bug: http://www.winehq.com/hypermail/wine-devel/2003/12/0158.html even though Alexander removed thread initialization from x11drv. So the first thing I did was apply this patch: Index: x11drv_main.c =================================================================== RCS file: /home/wine/wine/dlls/x11drv/x11drv_main.c,v retrieving revision 1.87 diff -u -r1.87 x11drv_main.c --- x11drv_main.c 30 Jan 2004 22:54:39 -0000 1.87 +++ x11drv_main.c 1 Feb 2004 18:02:26 -0000 @@ -332,6 +332,8 @@ /* Open display */ + if (!XInitThreads()) ERR( "XInitThreads failed, trouble ahead\n" ); + if (!(display = XOpenDisplay( NULL ))) { MESSAGE( "x11drv: Can't open display: %s\n", XDisplayName(NULL) ); I determined that the tests under user/tests were causing deadlock. The attached file debugrun1 shows this. Start the debugger with: winedbg user32_test.exe.so and repeat the steps I made, and the executable should deadlock at the call to XGetScreenSaver. (By the way, I used a version of the tests where I'd commented out all other tests except the test_SPI_GETSCREENSAVEACTIVE one, and that's why you only see "testing SPI_{GET,SET}SCREENSAVEACTIVE", but that's not important.) Next, I decided to investigate which mutual exclusion primitive is causing the trouble. This run is included as debugrun2. There are two threads involved: thread 0xb is the application main thread, and 0xe is a thread created by the main thread to generate the tests. Thread 0xb owns a critical section that 0xe wants, and hence deadlock. Note the call to "walk thread" in the beginning. Note also that I single-stepped thread 0xe right up to the call to RtlpWaitForCriticalSection that deadlocks. I also added some display commands to show you the details of the critical section in question. Now, if you look at what the display says you'll notice something odd: at first crit = 0x0011d1e0, but then it switches to 0x403112b8. And this is without any breakpoints having been set up within RtlEnterCriticalSection! So it can't be a context switch - it seems like a bug in the debugger. Or is this intentional in some way? Anyway, this critical section is the one the x11drv library sets up when XInitThreads is called. Next I attempted to find out where the main thread acquires the critical section, before the deadlock. This is attached as debugrun3. Notice that I worked around the odd debugger feature mentioned in the previous paragraph, by placing a breakpoint not at the entry point of RtlEnterCriticalSection, but a few next's later. This allowed me to add the condition crit==0x403112b8. The "crit" pointer seems to consistently stay the same between debugger sessions, so this works (for me at least). See how LockCount is 0, even though this is the first call to RtlEnterCriticalSection with crit==0x403112b8 during this session? It should be -1 for a critical section that is being acquired for the first time! So this made me suspect that the crit sect is acquired during initialization (and then not released), which is why I applied the following patch: Index: critsection.c =================================================================== RCS file: /home/wine/wine/dlls/ntdll/critsection.c,v retrieving revision 1.23 diff -u -r1.23 critsection.c --- critsection.c 5 Sep 2003 23:08:34 -0000 1.23 +++ critsection.c 4 Feb 2004 20:15:46 -0000 @@ -243,6 +243,7 @@ */ NTSTATUS WINAPI RtlEnterCriticalSection( RTL_CRITICAL_SECTION *crit ) { + if (crit==(RTL_CRITICAL_SECTION *)0x403112b8) TRACE("critsection=%p: LockCount=%ld\n", crit, crit->LockCount); if (interlocked_inc( &crit->LockCount )) { if (crit->OwningThread == (HANDLE)GetCurrentThreadId()) and then launched the debugger with: winedbg --debugmsg -all,+ntdll user32_test.exe.so (I didn't bother with making the reference to crit->LockCount thread-safe.) The result of this is attached as debugrun4. Notice this line: No debug information in ELF '/usr/X11R6/lib/libXrender.so.1' (0x40016000) See how after four calls to RtlEnterCriticalSection, LockCount starts to be 0? So a pretty good theory is that the critical section is acquired, and then not released, during the loading and initialization of /usr/X11R6/lib/libXrender.so.1. This theory is not bulletproof, which is why I attempted to see whether LockCount ever becomes -1 again, but the debugger consistently barfed on me (== crashed). Well, that's it for now - I'll let someone more knowledgeable in libraries and their initialization carry on with this, if the're interested. A final note: naturally, you most likely won't have the same address for the critical section as me, but you should be able to find out what it is if you redo the steps I made. Have fun! -- Sami

When you try to add the app the keys are created and then the treeview is completely rebuilt, I know, not the most efficent but it works. So, you click to add the app, the keys are created(but don't create since you can't modify your config file), and then the treeview is refreshed so your changes are lost. Chris
