That can't be used for a test case, for a test case I, or most likely someone elsewho has the ability and the time has to write code under dlls/msi/tests/db.c and make a program in windows to re-illustrate this bug. >From: "Jason Green" <jave27(a)gmail.com> >To: "EA Durbin" <ead1234(a)hotmail.com> >CC: mike(a)codeweavers.com, dank(a)kegel.com, wine-devel(a)winehq.org >Subject: Re: FW: RE: My 1.0 wish list >Date: Sat, 3 Jun 2006 12:02:15 -0400 > >On 6/3/06, EA Durbin <ead1234(a)hotmail.com> wrote: >> >>This problem in MSI spans a multitude of bugs. >> >>ATI demo(Rendering With Natural Light ) - bug # 4712? >> > >I noticed yesterday that just about every ATI Demo had similar >installer problems.

I have compiled a list of applications that are affected by the bug in which the query in ready_media_for_file() in MSI returns the wrong results, it returns LastSequence less than the file->Sequence being passed. Here is a detailed analysis of the multiple types of errors this bugs causes. Common debug outputs of this bug are: Error #1: err:msi:ACTION_InstallFiles compressed file wasn't extracted This error is usually caused by the results of the query returning a LastSequence number of Less than that of the working install media and the installer is trying to extract the file from the wrong install medium. Error #2: err:msi:extract_cabinet_file FDICopy failed err:msi:ACTION_InstallFiles Unable to ready media There is a zero in LastSequence Value of the Media table and the query in ready_media_for_file() returns it. For some reason the msi file has a zero in the LastSequence but its really a dummy cabinet file and doesn't exist. The file sequence being passed for the first file is most likely 1, and the query of >= 1 is returning 0 falsely causing this error. This problem in MSI spans a multitude of bugs. America's Army - bug #5139 J2SE - bug # 4280 Half Life 2 - bug # 5004, 4533 Dawn of War Demo - bug # 3749 E-Sword 6.5 - bug # 4251 Rush for Berlin demo - bug #5187 ATI demo(Rendering With Natural Light ) - bug # 4712? There are probably other bugs resulting from this, but the log doesn't detail it well enough, alot of them just have the debug dump at the end and not the pertainent msi err lines. I only included applications where it was obvious from the log, or I tested personally. >From: Mike McCormack <mike(a)codeweavers.com> >To: EA Durbin <ead1234(a)hotmail.com> >Subject: Re: FW: RE: My 1.0 wish list >Date: Sun, 04 Jun 2006 00:30:41 +0900 > > >You can send me as many mails as you like, but I'm not doing anything until >there's a test case showing the problem. > >Mike I wrote a test showing the results of the query in the wine installer and included the source code and resulting logs which clearly displays the problem. That's the best I can do. I'm not up to snuff on my C programming, nor am I familiary with how the official test case for wine is supposed to be layed out. If someone else wants to work on it then thats fine, but I layed out the problem, and debugged it, and I've proven this with code and resulting logs. This problem affects a multitude of applications in wine. If your not willing to work on it then either someone else can, or it can remain broken.

Alsa sound vs OSS with wine and riven
by Stephen Clark June 3, 2006

June 3, 2006

Hello, I have been working to get "Riven" the sequel to Myst to work with the latest wine from cvs on the latest FC5. It works and the sound is almost perfect with OSS, but is totally screwed up when I use ALSA, I don't know whether this is a WINE or Linux issue, so I am cross posting to both lists.

ntdll: a simple implementation of cross-process NtAllocateVirtualMemory
by tkho＠ucla.edu June 3, 2006

June 3, 2006

Hello, I ran across the need to do memory allocations across processes and came upon Alexander Yaworsky's patch at http://www.winehq.org/pipermail/wine-devel/2004-September/029953.html and took a different approach. Instead of waiting for the target process to check a fd, I changed the implementation to use ptrace to interrupt the target process and execute code in kernel32 that does an mmap/munmap. This is a simple implementation that does not do a full-on call to Nt(Allocate|Free)VirtualMemory inside the target process, mainly because the locks taken in the allocation management code would cause deadlocks. I've done informal testing to make sure the code doesn't crash Wine by running applications alongside this memory-churner: http://www.seas.ucla.edu/~kho/wine/alloc_test/alloc_test.exe http://www.seas.ucla.edu/~kho/wine/alloc_test/alloc_test.cpp One thought that has recently crossed my mind: Building off his framework and putting much of the code in the server may not have been a great idea, since the only real need for the server is to get the unix pid of the thread. Is this a step in the right direction? Comments appreciated!

Great. Can you package up the tests as Wine conformance tests? That would be very useful; it might even provide the nudge needed for an MSI expert to fix the problem. - Dan -- Wine for Windows ISVs: http://kegel.com/wine/isv

You don't need mozilla, but the Mozilla activex control : http://source.winehq.org/mozactivex I don't know why shdocvw doesn't prompt the user to install it in this case though (so I'm CCing wine-devel and Jacek to see if something has to be changed in nsembed.c).
