To <space> or <tab> or not :-)
by Molle Bestefich June 5, 2006

> isn't it rather insane to require specific editor settings > just to be able to *view* the code? It's a necessity for some editors. The TAB setting can be embedded in ASCII files, there are various magic comments that will cause vim and emacs to switch to a readable tabs setting. What is insane is 8 characters per tab. IMHXP 2 characters is too little to quickly make out the indentation. 3 and 4 are both fine choices. 4 wastes slightly more horizontal space, so I prefer 3. 8 is just nuts, it was probably written by someone who hates tabs and wants to use it as an argument to convince everybody to convert to spaces. Using spaces in place of tabs is bad, because you have to press <backspace> and <space> so much the more, wasting your time and tearing your fingers. And there's a higher risk of misaligning something - you have to pay more attention, which again is a waste of your time. You loose fine-grained control when you use tabs instead of spaces, but fine-grained control also means a jungle of bizarre rules about when-and-where-to-do-fine-grained-indenting, so it never pays off, rather it always ends up ruining the indentation anyway. By far the easiest solution is to just use tabs, and just indent codelines that span more than a screenful (7x chars or what not) with an extra tab.

Something like: ULONGLONG ret = (ULONGLONG)a * b; if (ret > 0xffffffff) will generate pretty much the same code with a recent gcc, and it's a lot more readable.

Ecco Pro hangs when accessing "2nd level" dialogs
by Don Dwiggins June 4, 2006

June 4, 2006

I'm a heavy user of Ecco Pro on Windows, and am trying to port myself as completely as possible to Linux (Ubuntu currently). Wine does a good job of supporting most of Ecco's features, but there are a couple of places (unfortunately important ones) where it hangs up tight. I've just submitted Bug #5335 about this problem. I'm a long-time programmer with good (if rusty) knowledge of C/C++ and Unix, just getting up to speed on Linux. I'm at the point where I might be willing to tackle this myself, if the learning curve isn't too steep. I'm posting this to ask for guidance on the best way to proceed. At least, if there's a good way to get more information on the hangup, I'm definitely willing to add to the bug report.

Shell integration idea
by Mikołaj Zalewski June 4, 2006

June 4, 2006

As a SoC project I'll try to improve the integration of wine with the Unix shells. My first step will be to implement the freedesktop.org Trash. I've written some code that doesn't add any new features but shows how I want to add it. I'd like to know if this is a good design? The main idea is not to hard-code one implementation of things like the Trash into shell32 - not everything is standardized by the freedesktop and even if it would this might not work on other systems like MacOS X. We should allow for many implementations. The correct one is loaded depending on a registry settings (so that a winecfg entry can be added). My implementation uses COM objects as it's standard dlls provides support for such tasks. Currently there is one interface (IWineShellIntegration) that acts as a factory for specialized objects. That could also be implemented using COM Aggregation - when we do that we could use QueryInterface instead of GetIntegrationObejct. Some COM objects can run in the address space of the calling process - e.g. the trash can be implemented like that. For others it would be a waist of resources (e.g. there is no need for every process to watch is the file associations have changed) - it's enough to load them only once. The explorer seems to be a good candidate to create such objects. In the attached patch there is one specialized interface - the IWineTrash. The SHELL_DeleteFile[AW] is patched to use it - it shows a different icon if the file can be trashed (these are not the correct icons as wine's shell32 uses a message box instead of a special dialog) and calls the trash method then. Currently there is only one built-in trash that can't trash anything. (note that SHELL_DeleteFile is called in the folders that are decendents of My Computer. If choose delete on a file that is a decendent of the '/', it will be deleted without a warning). Mikolaj Zalewski

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.

Hello, I have been working to get "Riven" the sequel to Myst to work with the latest wine from cvs on the latest FC5.

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).

But investigation modifications in x11drv to permit wine x pixmaps access for wined3d/opengl will fix many problems (but not hthe multiple pixel formats) Anyway we must move some code of wined3d and opengl32 (GLX code, etc...) to x11drv as it permit : - to handle this problems without hacks (ie many ExtEscape) - to help macos-X to port wined3d and opengl (all specific cost must be on x11drv/qwartwdrv) > Lionel (in 'not even time to read wine-devel' mode :-) ) > Well, at least i take time for it :) (and reviewing the flood of d3d patches) Waiting for you for coding :p Regards, Raphael

Re: How are we doing?

> Especially the code that is responded to as , I know it's a mess to > look at, but I didn't write it. Can you give us examples? Mostly Wine attempts to follow how Windows works, so MSDN provides a lot of the documentation. This is becoming increasingly true, with kernel32 being implemented on top of ntdll. There are bits that are hard to understand, certainly, and some areas could use some comments. Unfortunately sometimes the lack of comments demonstrates a lack of understanding, but the code works for someone, somewhere, so we're mostly afraid to touch it until some brave soul comes along. For example, SHFileOperation was a complete mess until James fixed it up. Another example is user32. It's impossible to document (in English) what it's supposed to be doing. For this, and many other cases, a good regression test suite is the best documentation: it tells you what's expected, so if you go mucking around you have checks against introducing regressions. I know you've been working with msi lately. The fact that you've figured out where the problem is indicates to me that it's adequately commented, even if the learning curve is still a bit steep. Patches to add API comments for the Wine API guide (http://source.winehq.org/WineAPI/ ) are always welcome. Patches to document dodgy bits of code may or may not be accepted, but regression tests to justify dodgy bits of code are happily accepted too. http://source.winehq.org/WineAPI/ --Juan __________________________________________________ Do You Yahoo!?

Hi all, Quartz driver is up to date on Darwine CVS. Winemine is playable on both PPC and x86 but it look fine only on PPC, x86 driver suffer strange rendering bugs. See wiki for building the driver : http://wiki.opendarwin.org/ index.php/Darwine:quartzdrv I will update wiki soon with issues and todo for Quartz driver. Cheers Emmanuel

No it must be doable without X changes (But X additions as GLX_EXT_texture_from_pixmap will help a lot). Only problem is to find time to fix it (as lionel, i have no time for now). Anyway i having a simple and downloadable application to reproduce this problem (not lightwave) must help. The only parts who really needs X change are for: - glShareList: sharing fb/visual config between exitings GLX contexts - dinput mouse management >I'm not sure lotus notes problems should block 1.0, as IBM has a native >Linux client now, but if someone wants to fix them (especially the ones >in usp10.dll netapi32.dll, that would be great. agree :) >> Note: it will be interesting to add user votes to wine-bugs (ala kde) to >> better see user needs. > >There are already user votes in bugzilla, that should suffice. >- Dan Oups i never seen it :) Regards, Raphael

Re: Missing LeaveCriticalSection on error paths (found by Smatch).

Asked Lionel Ulmer on irc and the patch is correct. But according to Stefan Dösinger that code will be replaced by his code "in the next couple of days". bye michael > --- > > dlls/ddraw/device_opengl.c | 2 ++ > 1 files changed, 2 insertions(+), 0 deletions(-) > > dd0b9b20d26984ae408c1a7727323a08d44e0d95 > diff --git a/dlls/ddraw/device_opengl.c b/dlls/ddraw/device_opengl.c > index d19996e..4c663a6 100644 > --- a/dlls/ddraw/device_opengl.c > +++ b/dlls/ddraw/device_opengl.c > @@ -3775,10 +3775,12 @@ static void d3ddevice_lock_update(IDirec > buffer_color = GL_BGRA; > } else { > ERR(" unsupported pixel format at device locking.\n"); > + LeaveCriticalSection(&(d3d_dev->crit)); > return; > } > } else { > ERR(" unsupported pixel format at device locking - alpha on frame buffer.\n"); > + LeaveCriticalSection(&(d3d_dev->crit)); > return; > } > > > > ------------------------------------------------------------------------ > > -- Michael Stefaniuc Tel.: +49-711-96437-199 Sr. Network Engineer Fax.: +49-711-96437-111 Red Hat GmbH Email: mstefani(a)redhat.com Hauptstaetterstr. 58 http://www.redhat.de/ D-70178 Stuttgart
