Endless loop in crash with MFC42
by Uwe Bonnes 03 Jun '02

03 Jun '02

Hallo, the XILINX webpack package crashes in some pull down menu. Some messageboc about an unrecoverable error pops up. On clicking OK, wine enters an endless loop in the debugger. It looks like appended: Bye -- Uwe Bonnes bon(a)elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ---------- Unhandled exception: page fault on read access to 0x00000004 in 32-bit code (0x5f442d54).

linux kernel thoughts
by William Knop 03 Jun '02

03 Jun '02

I'm sure people have asked questions about integrating wine into the linux kernel. Probably got flamed by everybody, yeah? But that's not what I'm posting about. Not directly, anyway. =) I'm thinking of writing a kernel patch for PE executable support. Is there any reason why wine libraries should not be used in a similar manner as standard linux libraries? Granted wine is more than just it's libraries. Anyway, good idea, bad idea? And please keep the "if it ain't broke, don't fix it" comments to yourself. No progress is made with that mentality.

LotusNotes - typed characters do not appear
by Andriy Palamarchuk 03 Jun '02

03 Jun '02

This bug exists for a long time. See bug 466 http://bugs.winehq.com/show_bug.cgi?id=466 There are comments that this issue is fixed in Codeweavers wine and Crossover Office. What is the reason the fix is not in the main tree? If the fix is too hackish I still would like if information about the cause was added to the bug description.

Wine front-end -- winespy
by Massimo 03 Jun '02

03 Jun '02

I am finishing a gui front end for wine that allows to start and stop wine app on the fly, capture wine output and filter debug cannels as required. It's done calling wine with --debugmesg +all and filtering it, so it'll slow down in some extents wine app.... For the moment I didn't find a way to remotely control wine debug channels from my app. I think that with little wine code changes it would be possible, i.e. passing a pipe to wine with something like --debugpipe num, and using it to start-stop debug channels output on the fly... But I can't code it.... If someone knows how to implement that stuff, I'd be glad to change my app... it would be much faster than now. BTW, I'll post my app (a QT based one) on next days after some testing. Regards Max

A problem with winmm and word
by Duane Clark 03 Jun '02

03 Jun '02

Word2000 seems to work good for me, except when I exit. It than invariably crashes in winmm, of all places: Backtrace: =>0 0x44056d9f (MULTIMEDIA_PlaySound+0x12f(pszSound=0x0, hmod=0x0, fdwSound=0x40, bUnicode=0x0) [mmsystem.c:639] in winmm.dll.so) (ebp=405b6bfc) 1 0x44056e37 (WINMM.DLL.PlaySound+0x13 in winmm.dll.so) (ebp=405b6c14) 2 0x30962b08 (MSO9.DLL._MsoFShowTooltip@8+0x123b in C:\PROGRAM FILES\MICROSOFT OFFICE\OFFICE\MSO9.DLL) (ebp=405b6d78) 3 0x30a92306 (MSO9.DLL._MsoFGetCursorLocation@8+0x23f in C:\PROGRAM FILES\MICROSOFT OFFICE\OFFICE\MSO9.DLL) (ebp=405b6d9c) 4 0x30170343 (winword.exe.EntryPoint+0x16d9a3 in C:\Program Files\Microsoft Office\Office\winword.exe) (ebp=307cd7d0) 5 0x00000012 (ebp=00000000) MULTIMEDIA_PlaySound() gets called three times. The first two times work ok, but on the third time, it is called with a NIL pszSound. This causes wps to never be set, causing the crash on line 639: wps->lpNext = iData->lpPlaySound; I added a simple test to return if wps is not set, and Word exits fine. But I have no idea whether that is the right thing to do.

Do you think it's REALLY needed > or is there non-solvable problems? I'm interested in the Wine project, in particular, the kernel module being developed to speed up execution of win32 programs. It would really benefit from what you're proposing. (Wine is currently starting to do its own SMB client stuff, probably using the same shared library you're proposing to use, but not in a way that would be usable by the wine kernel module, I think. Wine could use your enhanced smbfs, if present, to allow all file operations to be handled by the wine kernel module.) > > Question: how will you carry the SMB token around? > > Let's imagine somebody starts a script that runs two programs > > that access SMB shares, and that they're initially not logged in at > > all. > > If this were Windows, it would prompt them once for their username > > and password, and then allow access from then on. ... > > For The user/pwd problem, you are right, user should be prompted for a > password.

I favor #4, it's the simplest. When the time comes that somebody wants closer emulation of windows behavior, something fancier could be done. > For the token [itself], it could be a file on the disk: > /tmp/user.smb.token, like with kerberos If that's how kerberos does it, that's probably fine. (In fact, in the future, won't you just use kerberos for a lot of windows networks?) But it might be awkward to access from inside the kernel, so I can imagine you might want to store it inside your smbfs kernel module instead. > What about putting that in a ENV VAR? Nope, environment variables are not global enough. Some posters have proposed using autofs to do the mounting. That's a good idea if it saves work and lets you have the per-user semantics you want. So all you need to do is implement an smbfs that uses the user's token to validate each open/rm/mv, and you're done. (Modulo somebody hooking an smb browser into an ldap server, but that may already have been done.) - Dan

problem : win16 stack selector freed twice
by Christian Costa 03 Jun '02

03 Jun '02

Hi everybody, I encountered the following problem that completely broke MapLS. I investigated a little and here is what I've found : 1) a selector is allocated for the win16 stack in THREAD_InitStack 2) the selector is freed and the stack replaced by another (the DGROUP of the module) in NE_StartTask 3) MapLS is called, allocates the freed selector and keep it in a linked list 4) the selector is freed in SYSDEPS_ExitThread which believes it to be the selector of the initial task 5) the selector being freed is allocated (from where is not important) and the associated descriptor is modified 6) further call to MapLS (wich makes the function to use this selector) make wine to crash because the descriptor has been overwritten So 2) and 4) are conflicting but I think only 4) is wrong. 4) should free the selector of the new stack instead of the old one. Or should do nothing if the stack has been changed. Any idea? A+ Christian

Win16 Support again
by Steven Edwards 03 Jun '02

03 Jun '02

Ok I changed my mind, I want to disable it for now. What is going to be the best way to go about doing it? We currently have the -DNO_WINEWINSOCK should I just #ifndef the code out with -DNO_WIN16 ? Thanks Steven "Every revolution was once a thought in one man's mind" - Ralph Waldo Emerson
