I can't have a backtrace as i can't get winedbg working correctly on installshield programs :( But i'll send you the traces later (when i'll be back home).

It seems your approach is a new one and interesting, but I'm not sure this is how Windows does it. Does anybody know exactly what Windows does in this situation?

Bad wine today.
by Rein Klazes 26 May '04

26 May '04

Hi, I wonder if I am the only one that sees this with any windows prog that I try: |$ wine sol |x11drv: Can't open display: |Please ensure that your X server is running and that $DISPLAY is set correctly. |$ (other X programs run fine). I did the usual things when in trouble: a make clean, fresh cvs update. That did not help. Debugmessages "+all", does not give any messages. Version win98 or win2k makes no difference. Reverting to the yesterdays cvs, makes wine work again. Any idea? Rein. -- Rein Klazes rklazes(a)xs4all.nl

Crash and corrupted registry
by Christian Costa 25 May '04

25 May '04

Hi, This is the second time I had to reboot when by box is stuck while running a windows apps. In both case the registry had been corrupted. This is very annoying. Could we have the wineserver do a backup of registry files at startup so we can retreive the previous version if a corruption occurs? That would be very usefull. Thanks, Christian

Proprietary Hardware and related stuff - Get them work with Linux
by Gianfranco Luceri 25 May '04

25 May '04

Hello, I own a Matrox Mistyque with Rainbow Runner Studio and Rainbow Runner TV (not G-Series) add-on cards and there's no way of getting them all work with Linux due to the lack of documentation about a proprietary chip (MGA-something-I-cant-remember-any-more). The only supported OSes are Win95 (fully operational, not taking into account the Os flaws) and WinNT 4.0 (some "minor" features aren't available). Maybe WINE is the only way to get it (and similar hardware) work with Linux. Infact the driver and related software could be installed and executed with WINE, assuming that WINE could succesfully access the I/O port used by the hardware (and maybe linux is not even aware of that hardware!) Maybe I'll try that by myself and post the (maybe bad) results I'll get (at least a divorce from my wife). Any comments, hint, post wuold be appreciated. There's a lot o people owning a Rainbow Runner (not G-Series) or hardware with the same problem out there. So please help. Thank you. DonalDuck

I tried running the demo of Picasa from http://www.lifescapeinc.com/picasa/ under Wine-20040213 and Wine-20040505, but the installer just put up "Out of Memory" boxes :-( This progam uses some unusual installer app (it announces which one early on when you run it under Windows).

Thanks Scott, for the prompt reply. I tried the patch posted by Eric Pouech and still no luck, the program still appears to receive nothing back. I can type directly into the terminal a ATDT command to dial a number and I get a connect, but never see a response on the screen. I have tested it on several different machines with different wine builds, but could someone please test this, just to make sure that I am not doing something trivially wrong.

exec-shield patch 7
by Mike McCormack 25 May '04

25 May '04

Description: This patch allows platforms using exec-shield patch against the Linux kernel (eg. Fedora Core) to run Wine without disabling exec-shield. License: LGPL Changes in version 7: * fix bug that caused crash when CreateProcess was called * update to work with the new functions for reserving memory Changes in version 6: * include ulimit workaround * resolve conflict with recent patch to WineHQ CVS tip Changes in version 5: * reserve the shared heap area as well as the PE load area * allow multiple reserve areas in libwine Changes in version 4: * set the WINEPEEXEPATH environment variable correctly Changes in version 3: * reserve only the area required by the PE EXE if launched from CreateProcess (else just a default slab) * pass the reserved area to wine, so wine knows about it * unmap the preloader after it is no longer used Changes in verison 2: * replace the shared object loader instead of using a bootstrap exe Version 1: * create a bootstrap exe that reserves memory before loading wine-pthread or wine-kthread Index: dlls/kernel/process.c =================================================================== RCS file: /home/wine/wine/dlls/kernel/process.c,v retrieving revision 1.63 diff -u -r1.63 process.c --- dlls/kernel/process.c 25 May 2004 01:29:24 -0000 1.63 +++ dlls/kernel/process.c 25 May 2004 04:59:54 -0000 @@ -1257,7 +1257,8 @@ * * Build the environment of a new child process. */ -static char **build_envp( const WCHAR *envW ) +static char **build_envp( const WCHAR *envW, + const char *workdir, const char *unixpath ) { const WCHAR *p;

The corresponding Microsoft test takes hours to complete. If time is an issue, then the test should be split up into a quick test and an exhaustive test. Also, volume and pan tests on primary and secondary buffers is not the same thing as 3D. They just happen to be similar now because we don't support hardware acceleration yet.

failure report: Astrum installer
by Dan Kegel 23 May '04

23 May '04

Looking through the debug log for my failed attempt to install picasa, I saw that the installer it uses is called Astrum; see http://www.thraexsoftware.com/aiw/ A free demo of that installer is downloadable from http://www.thraexsoftware.com/download/aiw.exe Predictably, it doesn't run under Wine, either; it also puts up a dialog box at the beginning (which unhelpfully doesn't show any text), and if you click "ok", it just puts up the same dialog box again. I tried for a while to figure out WINEDEBUG settings that would provide some illumination about what's wrong. Best I came up with was WINEDEBUG=warn+all,+dialog,+text wine aiw.exe > log 2>&1 in hopes I could tell what the missing text was, but no dice. Given that this is a free-ish installer, and more apps might start using it than just Picasa, maybe it's worth looking into... - Dan -- My technical stuff: http://kegel.com My politics: see http://www.misleader.org for examples of why I'm for regime change

I discussed abstracting WINE user32/gdi32 and creating a Win32k.sys implementation for Wine so we could try to hide the x11drv behind it but at the time Alexandre does not seem very interested in the idea. The way it stands right now while WINE is more correct in its functionality its implementation is not 100% correct for the design we are trying to replicate.

Thanks Steven, However - just a thought here.. Do we want to simply work with the '.ttf' file, or should we keep the 'source' in CVS also?

I'm not really familiar with what extra data the '.sfd' file may have compared to the '.ttf' that may be useful. Is anyone familiar with this stuff?

symbol hiding - with gcc -fvisibility
by Guido Draheim 21 May '04

21 May '04

sorry, just saw the note on WWN. I did hope that there would be someone to point to the gcc visibility stuff already - but it seems that people are more concerned to exchange their believes and politics rather showing off some engineering stuff. * preface: it's not in the file format - it's in the tools. The name ELF stands for Extensible Linker Format, it allows to invent all kind of new sections, and expand the symbol table with many interesting attributes that can be checked up by a toolchain. Well, "IF" the tools check for them. * gcc -fvisibility The gcc -fvisibility exists since 3.1 and is supported by binutils. If you read up some web reports, it seems to have been invented for hiding stuff not quite unlike what the original poster wanted. The icc supports all -fvisibility options as well afair. * the real problem traditionally, one can kill local systems which are usable within one file only, i.e. "static". Pretty 20year old unix stuff. The other symbols are referencable outside (in .o) and the standard shard linker will put all of them into the shared library symbol export table. - But now we want two different symbol flavours, one exported to the same library, the others for the rest of the world. Perhaps use a linker script to decide later about symbol visibility. * example solution gcc supports the universal attribute syntax, and it does now know about more symbol flavours as to their visibility. Probably you want to have "hidden". Attached are two simple test*.c files and a makefile. The final sharedlib symbol table contains only test3 after stripping. - using a linker script instead of in-source __attribute__ is left as an excercise to the reader. * more hints search freshmeat - there are ELF tools to staticlink, to obfuscate, and more. It's all in the tools. There is only one problem with opensource: many programmers do not need to hide symbols to the extreme, so they did not write such tools so far. Not yet. There are some real ELF-educated people out there - hire one, and let him write the tool you need. The ELF format is well-defined and simple enough to allow everything and quite easily. Do ut des. -- cheers, guido http://google.de/search?q=guidod extern void test2(void); void __attribute__((visibility("hidden"))) test1(void) { test2(); //__attribute__((visiblity("internal"))) } extern void test1(void); void __attribute__((visibility("hidden"))) test2(void) { test1(); } void test3(void) { test2(); } test.so : test1.c test2.c Makefile gcc -Wl,-x -shared -o $@ test1.c test2.c strip -x $@ objdump -t $@ | grep "test[123]" gcc -Wl,-x -shared -o test.so test1.c test2.c strip -x test.so objdump -t test.so | grep "test[123]" 00000631 g F .text 0000000d test3

WINE filesystem idea
by Jonathan Wilson 21 May '04

21 May '04

Basicly, when emulated windows version is set to NT4, 2000, XP or 2003, WINE should pretend to apps that its running on NTFS. If running as 95,98 or ME, it should pretend to apps that its running on FAT32. Or better yet, add an option for this (with my suggestions being the default) Just an idea :)

Wine on AMD64 (heap problem)
by Maurizio Monge 21 May '04

21 May '04

Hello, i compiled wine cvs on my amd64 without many problem (i had to set PATH to point to a directory with wrappers for gcc,ld and as that would call respectively "gcc -m32","ld -melf_i386","as --32", it would be nice if wine would support natively this or would support LDFLAGS=-melf_i368.., but this is not the point). When i started wine i got: wine: failed to create the process heap The same wine executable was running ok on my 32bits distro. I read that this happens on fedora2 too because of nx stack, and i think that, even if i do not have SeLinux installed, the stack is not executable by default on amd64... Do you have any idea of how this could be fixed/hacked? Thanx Maurizio I am not subscribed to wine-devel, so please CC monge(at)sns(dot)it

Regression with Blizzard patching software
by Aneurin Price 21 May '04

21 May '04

I recently discovered that the software used by Blizzard to patch Diablo 2 and Warcraft 3 (and possibly the same version used with other games), has stopped working. It starts do do something, but before actually applying the patch it crashes out, with the final error message being: Unhandled exception: page fault on write access to 0x00000000 in 32-bit code (0x408ba2e0). In 32-bit mode. 0x408ba2e0 (DIALOG_CreateIndirect+0x300 [dialog.c:636] in USER32.DLL): movl $0x0,0x0(%eax) 139 return TRUE; Wine-dbg>WineDbg terminated on pid a The whole of the scrollback buffer is filled with the usual messages about loading debug information. I could run it with script to see what's happening before that, but I don't think it's really necessary: Since this *used* to work, I've gone through some CVS regression testing and determined that it stopped working sometime between 2004-04-19 22:00:00 and 2004-04-19 22:03:00 CST, so I'm willing to bet that this is what changed: http://www.winehq.org/hypermail/wine-cvs/2004/04/0272.html Since I have no understanding of what's going on here I really coudn't suggest a fix, but I'm happy to provide any further information I can and thought this would be worth pointing out.

some ideas for new janitorial projects
by Eric Pouech 19 May '04

19 May '04

I've been toying with some gcc warnings lately, and this could generate some new ideas for janitorial tasks. For example: o -Wmissing-declarations should point lots of missing APIs declarations (I've done it in some cases, and I'm in the process of submitting some fixes). We cannot turn this warning always on because there are lots of cases where we have global functions without prototypes (most than 2/3 of them are made out of the 16bit entry points) o -Wcast-qual should point out all the (const bla*) => (foo*) casts. We use quite a bit this, and in some cases it would prevent some errors. These are the main cases pointed out by this warning: 1/ const void* ptr; and then reading a value from ptr (word...) like *(WORD*)ptr which should be written *(const WORD*). The warning in this case is harmless. 2/ const void* ptr; and then setting it to another const pointer: const WORD* pw = (WORD*)ptr; which should be written pw = (const WORD*)ptr;. This warning is harmless if pw is really defined as const, in some cases it isn't and this should be fixed. 3/ const void* ptr; and then setting it to a pointer to a pointer (used a lot for qsort/bsearch... callbacks), when dealing with arrays of pointers. Here again, what's const is the first pointer, so const foo* f = *(const foo**)ptr is wrong, it should be const foo* f = (const foo* const*)ptr; This could be harmfull if not declared properly. Unfortunately, we cannot turn this warning on all the time because some C functions implementation would always trigger it (strstr for example), unless we use intergral values (not pointer) to cast from the const char* to the returned char*), and this is uglier IMO than the warning we try to avoid. Some others warnings could be used as well. Trying also the Intel compiler gave lots of interesting warnings (and a tons of not so usefull too). A+

Yes, i know that but the DMPerformance (and the default Graph assiocated) are sessions objects (they are only deleted on program exit) Most of the dmusic objects must be cleaned (released) at exit, It will be done when dmusic will be more complete >Rob Regards, Raphael

E-mail Virus
by Abby Ricart 18 May '04

18 May '04

Is it just me, or is some one posing as julliard(a)winehq.org and dmitry(a)baikal.ru sending e-mail virii into the mailing list? My ISP filtered it before I could get it, and it's a Windows virus so I doubt it could do very much damage. The virus is described as W32.Beagle.X@mm. Someone is being rather childish. The subject lines were: "Encrypted Document" "Hidden Message" and "RE: Text Message"

Getting the API's for Windows Applications
by Jacobus Erasmus 18 May '04

18 May '04

Is it possible to workout or read the API's that a specific Windows application use ? The theory is that it would be possible to estimate the amount of work needed to get a Windows app to work on Wine by calculating the number of API's that is not working or only half working and estimating the time it would take to correct these API's. By running wine-debug it is possible to get the API's used by an application. I'm hoping that there is some simpler way (although I'm not holding my breath) to read the API's used by an application directly from the .exe or .dll. I'm working on a utility that would collect this information and estimate the number of man hours it would take to get an application running on Wine. Also I'm hoping to build a utility that can collect stats on the API's being used in an application as well. The idea is to build a web page with these statistics for the applications that people want to run on a wine installation. If we can get some participation on the work and completeness of an API. It should be able to build a pretty accurate picture of the amount of work that needs to be done to get an app running under Wine. There is some other interesting side effects that I will not elaborate on until I have something in place (this is very simple but time does not permit. Somebody feels better equip to do this please say so) If not I will probably get arround to doing something this weekend. Cu jacobus(a)kewlconcepts.co.za
