smatch, something like the Stanford Checker
by Michael Stefaniuc 11 Feb '03

11 Feb '03

Hello, i always dreamed to have something like the Stanford Checker for Wine and some days ago i've seen on freshmeat smatch http://smatch.sourceforge.net/ . It's a project from KernelJanitors and it seems usefull, at least it's worth an entry on Dimi's janitorial page. A short description: Smatch is basicaly a patch to gcc-3.1.1 that makes the gcc dump out it's internal represantation of the code and a set of perl modules/scripts to ease the parsing of the dumped code. Most of the perl scripts are for the Linux Kernel but writing new scripts seems to be easy. I wrote (well, mostly adapted an existing script for the kernel) one script http://people.redhat.com/mstefani/wine/smatch/enter_leave.pl (if we decide to adopt smatch it should probably go to $wine/tools/smatch/) to find code path with missing LeaveCriticalSection's. Scripts to find some other usefull things like fd, DC, GDI obejects leaks should be easy to write. Comments? bye michael -- Michael Stefaniuc Tel.: +49-711-96437-199 System Administration Fax.: +49-711-96437-111 Red Hat GmbH Email: mstefani(a)redhat.com Hauptstaetterstr. 58 http://www.redhat.de/ D-70178 Stuttgart

Windows API script updated
by David Miller 10 Feb '03

10 Feb '03

I've updated my script to output imported_api.html which lists all of the dlls and the specific APIs imported from other dlls. Hopefully that is a bit more useful than just which dlls are imported. There is a sample output here: http://home.ptd.net/~compsol/imported_api.gz It is about 800kb gzipped. It was 7MB before compressing. :) If anyone is interested, the script is attached again. You'll need to run with -parse to get this HTML. Now, should exported APIs somehow be part of the HTML as well?

WS_EX_TRANSPARENT bug
by Felipe W Damasio 10 Feb '03

10 Feb '03

Hi, First of all, I'd like to thank Tony Lambregts and Sander van Leeuwen for helping me. Tony: Since I tested and saw that Sander's patch fixed, I closed the bug. That patch should definitely enter on mainline! Anyway, I'm here to report another bug: CreateWindow's flag WS_EX_TRANSPARENT doesn't do anything. Cesar Mello did a little example program which uses this flag: Both source and an executable are available here: ftp://ftp.elipse.com.br/pub/transp/transp-exe.tar.gz ftp://ftp.elipse.com.br/pub/transp/transp-source.tar.gz I'll enter this bug on bugzilla right away. Does anyone can help me with this? Thanks, Felipe

Hi all, I just (well, not "just": more like a matter of a whole week or so) committed about 170 or so new entries to the AppDB, thus reaching a count of 1523 distinct applications. I guess I'm feeling really exhausted now... Anyway, have fun browsing the site at http://appdb.winehq.org ! Andreas Mohr

press: International Herald Tribune review
by Dan Kegel 10 Feb '03

10 Feb '03

The review was of a Linux distro, but one of the big failings the reviewer cited was the inability to run "the Oxford English Dictionary on CD-ROM". http://www.iht.com/articles/86157.html --------- PARIS For several years now I have thought longingly about Linux, the power-to-the-people operating system that is said to be as stable as a rock, open and free and the embodiment of everything good in the world - in short, the exact opposite of Microsoft's Windows, both technically and politically. ... Early on, Lindows had claimed that it would be able to run all Windows programs, and it came with a utility called WINE that was supposed to make this miracle occur. In fact, it can run some Windows programs, Office 2000, for example, but can't run others, like Office XP. In general, the more sophisticated the Windows program, the less likely that WINE/Lindows is going to be able to run it. Lindows has changed its position. They've realized that trying to piggyback on Windows programs is a recipe for frustration, and WINE is no longer part of Lindows. The current view, Schwartzman said, is that "if there's a Linux alternative, you're going to have a better experience." ... I use GotoMyPC all of the time to access my home computer from other places. It doesn't work with Linux. I have the Oxford English Dictionary on CD-ROM, which I also use all of the time. It, too, does not work with Linux. There are too many programs for which there is no Linux alternative. . Lindows is a bold and commendable effort to challenge the Microsoft hegemony and make computers cheaper. Unfortunately, it fails. ---------- -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

SW_SHOWMINIMIZED bug
by Felipe W Damasio 10 Feb '03

10 Feb '03

Hi, SW_SHOWMINIMIZED has a weird bug: The application, when restored, goes blank and have to be killed and re-started to work again. This looks like an internal loop inside wine, or a wrong XLib flag being set. Cesar Mello (mello(a)elipse.com.br) wrote a little app to test it, and both the source and an executable are available for download here: ftp://ftp.elipse.com.br/pub/showWindow/showWindow-exe.tar.gz ftp://ftp.elipse.com.br/pub/showWindow/showWindow-src.tar.gz Can anybody help me with this? This seems to be critical, because to app does not work anymore untill it is re-started. I'll add an entry to bugs.winehq.com now. Thank you and kind Regards, Felipe

Started playing with Wineserver on mingw/cygwin again
by Steven Edwards 10 Feb '03

10 Feb '03

well I made it serial.c before I had to run to work. I'm having good luck getting alot of the objects to compile so far I've only had to kill file.c, ptrace.c, request.c and select.c. Getting this to build and run on Windows is going to be a bitch =) gettimeofday, fork and all of fd and networking is going to be the hard part. I've started a tempory header to see what will need to be implemented in libwine if we want to get wineserver up and running on Windows without cygwin. Cygwin still really needed get/setthreadcontext (hint, hint) Thanks Steven /* I kill'd file.c, ptrace.c, request.c, select.c * * get/set thread context still needs to be done for Mingw and Cygwin * * main.c needs a lot of work */ /* object.h and async.h */ struct timeval{ int tv_sec; int tv_usec; }; /* debugger.c */ #define SIGTRAP NULL /* file.c - doesnt work */ #define O_NONBLOCK 0 #define POLLIN 0 #define POLLOUT 0 #define POLLIN 0 #define POLLOUT 0 /* main.c */ #define SIGPIPE NULL #define SIGHUP NULL #define SIGQUIT NULL /* named_pipe.c */ #define PF_UNIX NULL #define SOCK_STREAM NULL /* object.c */ #define POLLERR 0 #define POLLHUP 0 __________________________________________________ Do you Yahoo!?

IPCWorkshop
by Dan Kegel 10 Feb '03

10 Feb '03

There's a fun little test app (with source) called IPCWorkshop at http://www.codeproject.com/threads/ipcworkshop.asp I noticed it probably needs a Sleep(500) in its Mailslot receive loop, and a lot of its stuff doesn't seem to work on my Windows Me system, but its "filemapping" and "mailslots" modes do seem to work on Windows Me. (Oddly, "Clipboard" doesn't work for me on Windows Me. This app is fairly new, maybe it's still a bit buggy.) None of its modes seem to work on Wine. Not sure why. In server mode, it never redraws, so the GUI is messed up somehow. I'm sure this app triggers several Wine bugs. Anyway, if anyone's looking for simple test apps that exercise various IPC methods, this one might be worth checking out. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

visual studio 6 not happy?
by Dan Kegel 10 Feb '03

10 Feb '03

wine cvs doesn't run visual studio 6 especially happily. Building a simple app fails with "Error executing rc.exe". I wonder if this is another example of that named pipe failure... it certainly is calling PeekNamedPipe to beat the band, and http://www.microsoft.com/msj/0698/win320698.htm says that vcspawn.exe (used to run external processes) probably uses named pipes to communicate with msdev. Guess it's back to the commandline for me. Yep, exporting a makefile and building with nmake works better. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Windows API (What I have so far)
by David Miller 09 Feb '03

09 Feb '03

I thought a few of you might be interested in the current status of this script, so here is an update. I will attach a copy in case anyone wants to test it, or add functionality or fixes. I'd be interested in the results of any tests, especially if you discover any parsing errors. It is far from complete, but at this stage does the following: - Scan a given path, locating all dll files - Generate an HTML map of dll imports only (sorted, lowercase, stripped of paths) - dumpbin /import and dumpbin /export on all dll files and save the results in imports.txt and exports.txt respectively - parse imports.txt as follows, and save the results in imported_api.txt: DLL name imported DLL imported API - parse exports.txt as follows, and save the results in exported_api.txt: DLL name exported API Future plans: - Create a matrix of data currently in HTML map - Generate HTML cross reference of all imported/exported API - Implement dumping of data into a database (Something queryable, but what?) - Detect and report unimplemented APIs in wine

More on the Treeview
by Drew "DanteAliegri" Ogle 09 Feb '03

also, when I replaced the comctl32 with a native, it didn't fix the problem, so I'd think its safe to say that the error is occuring outside comctl32.. -Dante

Tried to install Red Alert - Yuri's Revenge
by David.Goodenough＠DGA.co.uk 09 Feb '03

09 Feb '03

and it failed. The installer said that comctl32.dll was too old, did I want a new one, so I said no. They it said that DirectX was a level 0 (well actually a long list of 00.00s), and asked if I wanted to install what looked like version 4 (although the docs with the CD say that it will install 8.0a). When I said no to that the installer quit. This was a Debian unstable system, which is using the latest Wine.deb. So how is it detecting the age of comctl32, and how should I convince it that the dll really is up to date, and do I need to install the front bits of DirectX in order to use the support that Wine is now increasingly providing, or should Wine be advertising its DirectX support differently. This is the first time I have tried to install a DirectX program on the machine, and I do not know quite how I should proceed. Thanks in advance David

Treeview Regression
by Drew "DanteAliegri" Ogle 09 Feb '03

09 Feb '03

There has been a treeview regression, since at least 20030115, I assumed someone would take it up, but noone has. I will try to fix it, but a rather simple testcase ( ~200 lines of C ) is at http://open-socket.dyndns.org/~dante/treeview-testcase.tar.bz2 What appears to be happening, is when the dialog recieves a message that is WM_NOTIFY , it excpets the lparam to 1) be LPNMHDR, and lparam->code to be TVN_SELCHANGED. the lparam->code that wine appears to be returning is 0. -Dante

IDA regression again :-)
by Lionel Ulmer 09 Feb '03

09 Feb '03

Hi all, Seems that with latest CVS, the ncurses driver 'added' a lot of regressions to IDA... The biggest gripe is that the mouse support is VERY flaky (I can click some times but once it stops working, it seems that I cannot do anymore with it). As I do not know exactly how to select stuff in the GUI using only the keyboard (which seems flaky too as the Backspace and Delete key seem not really to work), I am a bit stuck. How could one help debug this relatively crucial application to help in some D3D / OpenGL investigations ? Lionel PS: we REALLY should be able to use the old slow as hell graphical driver as a fallback.... -- Lionel Ulmer - http://www.bbrox.org/

Good source of test case source?
by Dan Kegel 09 Feb '03

09 Feb '03

Source code downloaded from any *.microsoft.com server is copyright Microsoft, and they would not take kindly to us using it in our regression test suite, I'm sure. I hope I speak for everyone here when I say it seems important to carefully obey the letter of the law when it comes to avoiding copyright issues that might taint our efforts. So where should a developer go to find good code snippets when writing Wine regression or compliance tests, without running afoul of copyright laws? One possibility is http://www.codeproject.com. Their submission page, http://www.codeproject.com/info/submit.asp, quite clearly states: "If you post to CodeProject then you retain copyright of your article and code. You also give CodeProject permission to use it in a fair manner and also permit all developers to freely use the code in their own applications. ... You are more than welcome to submit code that is already published at another site, provided you own the copyright on that article, and provided you have not given the other site exclusive rights to your article." That sounds like code at CodeProject is fair game. Do other (smarter) people agree? I ask, of course, because I'd like to make sure it'll be ok to submit a testcase based partly on CodeProject code.

Error installing iKernel.exe: (0x1400)
by Dan Kegel 09 Feb '03

09 Feb '03

This is something I see frequently. Here's my little FAQ about it: When running an Installshield 6 installer: If you get the error "Error installing iKernel.exe: (0x1400)" at any point, it's probably because there are leftover processes from a previous try. You can verify this with the command $ ps augxw | grep wine If that command shows old copies of wine running your setup, you need to kill them before you can run the setup program. If there are no other Wine programs running, you can kill them all with the command $ killall wine If you're also running Wine programs you care about, you'll have to kill off the old Setup instances one by one using kill and the individual PIDs (or perhaps Wine's spiffy Task Manager, which doesn't exist yet). Then repeat the ps to make sure the old wines are gone. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Re: Fix module entry deallocation in MODULE_DecRefCount
by Warren_Baird＠cimmetry.com 08 Feb '03

08 Feb '03

>the fix doesn't seem the right one... could you post a -debugmsg >+file,+module of what really happens here The places I've seen it happen are in parts of a large and complicated program - I'll see if I can find a simple test case that repros the problem and post a trace here. But I can give you more details on what I found happening... After calling LoadLibrary("foo") there were two entries for library foo in the MODULE_modref_list. When you unloaded the library the first entry found was removed, but the 2nd entry remained, but the memory behind it didn't exist any more. If you tried to load the library again, the loading code would find the entry in the modref list and try to reuse it, and immediately segfault... I seem to recall that the first entry had the correct path to the library, and the send entry had "C:\windows\system\foo.dll" or something like that... Note that I've only observed this on a sparc/solaris system - it may be due to a pecularity of the way libs are loaded there... If I can repro it with a simple enough case to generate a reasonably sized log, I'll post it here, hopefully tomorrow... Warren

OLE speed, builtin vs. native
by Dan Kegel 08 Feb '03

08 Feb '03

I'm testing an Installshield 6 setup program tonight against wine-20030115 remotely over a 1Mbit/sec link. Running native $ wine SETUP.EXE takes 1 minute 40 seconds to put up the main dialog. With the DLL overrides $ wine --dll compobj,storage,ole,ole2,ole32,oleaut32,rpcrt4=n SETUP.EXE it takes 1 minute 10 seconds. So our OLE seems to be noticably slower. I imagine we'll fix that up before 1.0. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Various Visual FoxPro bug reports filed
by Paul McNett 07 Feb '03

07 Feb '03

Hello, I just filed 5 bug reports (1263-1267) regarding various issues with Microsoft Visual FoxPro. These represent some of the most obvious issues, but I'm sure I'll find more as I move my Visual FoxPro development over to Linux from Windows. I have a demo Visual FoxPro application that demonstrates these issues and a few more that I haven't reported in BugZilla yet. You can get this app from my site at: http://www.paulmcnett.com/vfp/testwine/ I'll be updating this app as new issues are discovered and old ones resolved. I'll now take this opportunity to thank everyone here for making Wine what it is today: you are giving me the ability to move off of Windows completely and yet still use my favorite development environment. Kudos to everyone involved! -- Paul McNett - p(a)ulmcnett.com Hollister, California, USA
