OpenOffice 2.0 beta 2 installs ok but locks up in File Open dialog with wine-20050830 + 2 patches
by Dan Kegel Sept. 14, 2005

Sept. 14, 2005

With wine-20050830 and Mike's two MSI patches (thanks, Mike!), http://openoffice.mirrors.pair.com/ftp/stable/2.0beta2/OOo_2.0beta2_Win32In… installs properly, and the app even appears to come up normally! However, when you use the File Open dialog box, it seems to lock up. Here's a session log: [dank(a)localhost program]$ wine soffice.exe fixme:advapi:LookupAccountSidW ((null),sid=0x7ad47428,0x7b949ac4,0x7b949bcc(256),0x7b9497c0,0x7b949bc8(256),0x7b949bc4): semi-stub fixme:font:GetKerningPairsW (0x6dc4,0,(nil)): almost empty stub! fixme:font:GetKerningPairsW (0x6dc4,0,(nil)): almost empty stub! fixme:font:GetKerningPairsW (0x6dc4,0,(nil)): almost empty stub! fixme:font:GetKerningPairsW (0x733c,0,(nil)): almost empty stub! fixme:imm:ImmGetContext (0x10030): stub fixme:imm:ImmReleaseContext (0x10030, 0x7bca5658): stub err:ole:CoInitializeEx Attempt to change threading model of this apartment from 0x2 to 0x0 err:ole:CoInitializeEx Attempt to change threading model of this apartment from 0x2 to 0x0 err:ole:CoInitializeEx Attempt to change threading model of this apartment from 0x0 to 0x2 fixme:commdlg:GetFileName95 Flags 0x02800000 not yet implemented That CoInitializeEx error sounds bad. The error is probably very easy to reproduce, perhaps a wine developer should try it out him/herself. Now to go rescue my wife so she can get some sleep. Having a two-year-old son seriously cuts down the amount of time I have for hacking. I'm doing a talk on Open Source this Thursday night. Mike's amazing turnaround time on the two MSI patches will be a nice story to tell during the talk. Is there any hope of continuing the run of good luck, and actually getting Wine to run OOo2.0 by Thursday? I dare not hope... - Dan -- Trying to get a job as a c++ developer?

Stack overflow problem
by Vitaliy Margolen Sept. 14, 2005

Sept. 14, 2005

Once more I need your help. It seems that wine is not correct with the way it sets guard pages for stack. Here is an example that works fine on windows, and fails on wine. And yes, I do have a program that does something like this: PDWORD p = TEB.Tib.StackLimit; *p = 0; I'm not sure what to do here. It looks like there are several places that we allocate stack, and both of them set first page (last for stack) as a PAGE_GUARD. Could that be that this wasn't what we wanted? Since both places using size of 1. But this looks like sets whole page to be guard page. -- Best regards, Vitaliy

Yes, it does remove the messages about buffer underruns, but it also introduces a delay in the playing of many tests, so they fail with the message "sample played for 1504 ms instead of 1000 ms", with varying values for the actual value of the delay. However, all of these problems went away when I modified my modprobe.conf file: alias eth0 via-rhine alias snd-card-0 snd-via82xx alias snd-card-1 snd-via82xx-modem options snd-card-0 index=0 options snd-via82xx index=0 dxs_support=5 remove snd-via82xx { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-via82xx alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd options parport_pc io=0x378,0xe800 irq=7,none options lp parport=1 alias char-major-4 8250-pci alias char-major-29 savagefb I added the dxs_support=5 option to the snd-via82xx module, and now the tests play correctly. The odd thing is that, when the dxs_support option, I can no longer trigger the buffer underrun message, even without the patch. But since the patch did not make anything worse in any of the actual games I have (with or without dxs_support), I kept it applied.

For example in the UK the OEM font would be vga850.fon while in the US it would be vgaoem.fon. Huw.

Looking for bugs in Wine's Microsoft Installer (MSI) implementation
by Mike McCormack Sept. 13, 2005

Sept. 13, 2005

Hi All, If anybody is aware of any cases of Wine's Microsoft Installer code not working, please log them in Wine's bugzilla (http://bugs.winehq.org/) assign them to me, and I will attempt to fix them. Make sure to set "msi" = "builtin", "*msiexec" = "builtin" when testing your installers, and if possible test with the latest Wine CVS. If the installer is available as a free download, please include a link to it. thanks, Mike

GetIDsOfNames
by Walt Ogburn Sept. 13, 2005

Sept. 13, 2005

Hi guys, Eric Tanguy asked on wine-users a while back about getting some geography games (http://olivier.leflon.free.fr/jeux/jeux.htm) to run. These seem to be Visual Basic, so oleaut32 issues come up. We succeeded with the first one (departments of France - font size problem fixed). Next, there is the issue that some of them call GetIDsOfNames on ole font objects (countries of Europe, http://olivier.leflon.free.fr/jeux/europe.htm) OLEFontImpl_GetIDsOfNames is currently a stub. What's needed is basically just to convert the strings "Name", "Size", "Bold", etc. into DISPID_FONT_NAME, etc. In particular, this game only needs "Size." It's not hard to code that, and make the game work. I'm not sure, though, what the proper approach would be for an acceptable patch: 1. Just code in the string comparisons, ignoring the locale. (Google provides no evidence that the property names vary by locale). 2. Call GetTypeInfo to get an ITypeInfo, and call DispGetIDsOfNames on that. I think this means that the information should be extracted from stdole32.tlb. Currently this doesn't find any match for these property names. Do they need to be added to stdole32.tlb somehow? 3. Something else. Any ideas? Thanks, Walter

Need help debugging a memory corruption bug in shfldr_unixfs.c

The relevant code in LISTVIEW_GetItemT is (dlls/comctl32/listview.c, line 5126): /* find the item and subitem structures before we proceed */ hdpaSubItems = (HDPA)DPA_GetPtr(infoPtr->hdpaItems, lpLVItem->iItem); lpItem = (ITEM_INFO *)DPA_GetPtr(hdpaSubItems, 0); assert (lpItem); It's the first call to DPA_GetPtr that crashes. So the structure pointed to by infoPtr seems to be corrupted (infoPtr is a LISTVIEW_INFO *, which represents the listview item and which given as the first parameter to LISTVIEW_GetItemT). As I never saw this with the original shfldr_fs.c code, I assume that shfldr_unixfs.c has a memory corruption bug somewhere. I've tried to figure the problem for some time now, but to now avail. So my questions are: 1) Can someone give me some advice on how to debug such a problem? 2) Did other people see this bug already? 3) Would valgrind be of help to debug this? Thanks, -- Michael Jung mjung(a)iss.tu-darmstadt.de
