Developer reminders tracker bug?
by Mike Hearn 10 Feb '04

10 Feb '04

At the moment there is no way in CVS to organize bugs filed by developers to remind us of stuff we should fix, as far as I know. In the past few days at least 3 such bugs were filed: 2000: %ProgramFiles% is not set in environment [me] 2003: WindowFromPoint Returns Wrong Window [rob] 2004: Bug In LVM_GETNEXTITEM(hWnd, -1, LVNI_FOCUSED | LVNI_SELECTED) [rob] I think we should have a way to keep track of misc (small) buglets found but for whatever reason not fixed in bugzilla, so when one of us is bored (tee hee) there is a ready supply of nice descriptions of bugs probably with fixes described too. Perhaps there should be a tracker bug for "Bugs filed by people with nice descriptions of what is wrong that are fixable in a reasonable timeframe by anyone", to separate out the random flotsam & jetsam that accumulates in bugzilla over time. Thoughts? thanks -mike

Alternative implementation of DocFiles (long, posted for archival purposes)
by Troy Rollo 10 Feb '04

10 Feb '04

The attached file contains the CorVu implementation of DocFiles (the Microsoft compound file format). This was coded from scratch based on analysis of the file format some time in or before 1998. There was no reliance on the LAOLA project, and there are several aspects of the DocFile format that are implemented in this code (and documented in docfile.h) that are not documented by the LAOLA project and not implemented in Wine. Because it's in C++, it's not directly usable in Wine, but it may be of use to anybody seeking to improve the Wine implementation of DocFiles in the future. The code is being released under the LGPL.

The block size for + * the standard VTOC is 512. The block size for the internal VTOC + * is 64. + * + * Now, the 109 blocks in the VTOC of VTOCs allows for files of + * up to around 7MB.

Well, there's an entry in the header block which + * points to the first block used as additional storage for + * the VTOC of VTOCs. + * + * Now we can get up to around 15MB.

That's right - the last entry in each + * block extending the VTOC of VTOCs is, you guessed it, the + * block number of the next block containing an extension to + * the VTOC of VTOCs. The VTOC of VTOCs is chained!!!! + * + * So, to review: + * + * 1. If you are using a FAT file system, the location of + * your file's blocks is stored in chains. + * + * 2. At the abstract level, the file contains a VTOC of VTOCs, + * which is stored in the most inefficient possible format for + * random access - a chain (AKA list). + * + * 3. The VTOC of VTOCs contains descriptions of three file level + * streams: + * + * a. The Directory stream + * b. The Data stream + * c. The Data VTOC stream + * + * These are, of course, represented as chains. + * + * 4. The Data VTOC contains data describing the chains of blocks + * within the Data stream. + * + * That's right - we have a total of four levels of block chains! + * + * Now, is that complicated enough for you? No? OK, there's another + * complication. If an individual stream (ie. an IStream) reaches + * 4096 bytes in size, it gets moved from the Data Stream to + * a new file level stream. Now, if the stream then gets truncated + * back to less than 4096 bytes, it returns to the data stream. + * + * The effect of using this format can be seen very easily. Pick + * an arbitrary application with a grid data representation that + * can export to both Lotus 123 and Excel 5 or higher. Export + * a large file to Lotus 123 and time it.

System Error H80010108 (-2147417848)
by Fabian Cenedese 10 Feb '04

10 Feb '04

Hi Did I already mention what I think of VB?... I try another VB program with an embedded ocx on wine and it gives me a dialog with the above mentioned error message. Then it just quits. After looking on the internet I found some explanation of this error: Run-time error '-2147417848 (80010108)' automation error The object invoked has been disconnected from its clients. But that doesn't tell me what's wrong. In the trace logs I can see it build and display this message but nothing that would show what went wrong before. Does anybody know this error or its reasons? Thanks bye Fabi

Guess I needed a little motivation to put together my pictures. Here's what I took @ WineConf: http://users.theshell.com/~vinn/wineconf2004/ As far as the movie editing goes: - There were some funny comments when Alexandre was talking about NPTL support in his presentation. - Something from Dimi's 0.9 list would be nice - Graphical stuff is always nice to look at. So Gav's demo of Alice, Lionel's of 3DMark2000, and the ReactOS demos would probably fit in there well. --------------- Brian Vincent Copper Mountain Telecom vincentb(a)coppercolorado.com

Stack size
by Robert Lunnon 10 Feb '04

10 Feb '04

I have a program which used to work under wine but now seems to fail due to a stack overflow. Unfortunately I'm no windows expert, but I vaguely recollect that tthe stack size for a windows program is declared in the PE executable header. Does wine honour this setting and can someone point me at a utility (preferably a unix one) to change it ? Thanks in advance Bob

NT services ...
by Lars Segerlund 10 Feb '04

10 Feb '04

I think I have an idea about NT services which is doable in the current framework. So what do you guy's think about spawning a second daemon handling the nt-services fron wineserver ? This could be done optionally ( services/noservices) and they can talk to each other on a unix socket ? Alternatively, you could run the service daemon as a common user on the system and fork off specific wine instances for each user who had registered a service running at an interval ? All these scenarios can easily be handled by the proposed setup, on ly a bit of different setup would be needed. Any comments ? I just wanted to know if I was thinking in the right tracks and if anybody has an estimate about how hard an undertaking like this would be before getting into the effort. / regards, Lars Segerlund.

CPUID update to update
by Robert Lunnon 10 Feb '04

10 Feb '04

For anyone who is using my previously submitted patch here is an update. It fixes the latent file descriptor leak, and patches a hole where have_cpuid was retained from the legacy code (Dunno how I missed that one) this ended up diving into the middle of the cpuid machine code where have_cpuid is defined (For different reasons). Since my original submission is not being incorporated into the wine codebase, I am posting here instead. It just might be useful for someone out there... bash-2.05$ diff -c cpu.orig.c cpu.c *** cpu.orig.c Tue Feb 10 23:31:27 2004 --- cpu.c Tue Feb 10 23:39:15 2004 *************** *** 116,122 **** { if (strstr(line,"processor") )count++; } ! if(count>0) return count; } #endif /* linux*/ --- 116,126 ---- { if (strstr(line,"processor") )count++; } ! fclose(f); ! if(count>0) ! { ! return count; ! } } #endif /* linux*/ *************** *** 193,202 **** "\tandl $2097152,%%eax\n" "\tandl $2097152,%%ebx\n" "\txorl %%eax,%%ebx\n" !

Acknowledgment page
by Tom 10 Feb '04

10 Feb '04

Hello All, I have decided to volunteer to do the "Acknowledgment page" It will be short and simple and here are my plans. After Brian sends his update to the "Who's Who" page I will list everyone that has been removed from that page onto a "Acknowledgment page". Here is my problem :) I have only been involved with this project for the last 18 months so I have no idea of who some of the major contributors were! Here is a short list of past developers that i'm aware of, and the work that they did. Bob Amstadt Guy Albertelli David Hammerton Peter Hunnisett György 'Nog' Jeney Tony Lambregts Douglas Ridgway John Sheets Are you guys aware of past developers who did major work and who are not listed here or on the current "Who's Who" page? I will also link to the AUTHORS page for a full list of current and past developers. All feedback is most welcome! Tom

NHL2004 D3D8 crash
by Abdul-Haseeb Ahmad 10 Feb '04

10 Feb '04

i have finally gotten nhl2004's menus to work the way its supposed to.. going into the game it crashes however.. i've attached a +d3d trace of the error output (here: http://bugs.winehq.com/attachment.cgi?id=530&action=view). the game does some d3d8 stuff before it goes into the menu.. and then once you click on the play button to go ingame the resolution changes, and it does a whole bunch of d3d stuff again and crashes... one thing that may or may not be interesting to note here is that the resolution list in the display options is empty... the installation instructions look pretty lengthy, I'm not sure if you *have* to install all of these, but most of them made a difference when i did install them... you can (and *should*) skip the Flash installation, because its not necessary, and when flash IS enabled, it makes everything else on the screen flicker... if you have the time i'd appreciate you'd check it out... 1. installed IE6 via mike hearn's script (wine20031212) - can switch to winex cvs after installing ie6, although ie6 wont be functional standalone 2. installed DCOM98 with "ole32, oleaut32, rpcrt4" native 3. changed dlloverrides to following: [DllOverrides] ;dcom "ole32" = "native" "oleaut32" = "native" "rpcrt4" = "native" "oleaut32.dll" = "native" "olepro32.dll" = "native" "comcat.dll" = "native" "ole32.dll" = "native" "rpcrt4.dll" = "native" ;ie6 "mshtml" = "native, builtin" "shfolder" = "native, builtin" "shell32" = "native, builtin" "shell" = "native, builtin" "shdocvw" = "native, builtin" "shlwapi" = "native, builtin" "urlmon" = "native, builtin" "crypt32" = "native, builtin" "wininet" = "native, builtin" ;default ;"oleaut32" = "builtin, native" ;"ole32" = "builtin, native" "commdlg" = "builtin, native" "comdlg32" = "builtin, native" ;"shell" = "builtin, native" ;"shell32" = "builtin, native" "shfolder" = "builtin, native" "shlwapi" = "builtin, native" ;"shdocvw" = "builtin, native" "advapi32" = "builtin, native" "msvcrt" = "native, builtin" "mciavi.drv" = "native, builtin" "mcianim.drv" = "native, builtin" "msi" = "native, builtin" 4. installed InstallShield 5. installed Java 2 Runtime Environment 1.4.2_02 - gives an error, but it still is installed 6. installed MDAC 2.8 - set "setupapi" = "native" before installation - set "odbc32" = "native" after installataion 7. installed Jet 4.0 SP8 9x/NT - set "imm32" to native before installation - copied native win98se "setupx.dll" to system dir and set to native in config 8. installed Windows Script 5.6 98/ME/NT 9. installed Shockwave Flash 6 redistributable from NHL2004 CD (Shockwave_Installer_Full) - can just regsvr32 Flash.ocx from your windows install - can be obtained from www.macromedia.com/support/shockwave/info/licensing/ as well by signing up - will give an error registering Flash.ocx with redistributable, break program at this point - copy tmp/IXPxxx.TMP/Flash.ocx to system/Macromed/flash/ - run install again, or wine regsvr32 Flash.ocx 10. installed nhl2004 demo from ftp.ea.com/pub/easports/demos/nhl2004/NHL2004Demo.exe - must apply the intro.html hack and the game_setup_interface.js hack from http://bugs.winehq.org/show_bug.cgi?id=1970 (make sure you get the game_setup_interface.js for the DEMO version, not the RETAIL version
