More winecfg todos

You probably want to increase the size of the drive mappings list so it fills the tab, currently there is just a lot of empty space at the top of the pane now you removed the old stuff. Also we should kill the autodetect button. This is done by wineprefixcreate these days, or should be. Other things are: - Drive editing seems broken. The list box only updates the second time I hit edit. err:winecfg:applyDriveChanges unable to set volume label for devicename of 'H:\', label of '' - Browse in the "Add/Edit drive" dialog is a WRITEME - Build system isn't right: I did a cvs update but the res files weren't recreated properly. I had to do a make clean to get the gui updates. - "Add Application" has poor usability: we always use a file browser dialog box even though the most common use case is just "foo.exe", ie the user knows the name and doesn't care about the location. Worse we start in the c:\windows\desktop folder for some reason, meaning users might accidentally select a .lnk file! Ditto for Libraries tab. - The Add/Remove application buttons are *way* too big! - Obviously, once audio autodetection has been moved into the drivers we need to kill the audio tab. - Libraries tab just has generally poor usability, actually. The first item in the radio group is "Builtin" meaning that's the one users are most likely to select, it should be "builtin, native" followed by "native, builtin" - We ask the user to understand a magic * symbol to set the default - what is up with that? - There are no helpful default entries in the drop down box for setting a DLL override, and when you add one the tree does not expand so to actually *set* it you have to expand the tree then select the new override. - We have way too many (eg, more than zero) tree controls in this app. - Drive mappings list is really unclear, there's no separation between the "Drive X:" label and the unix path its mapped to. Basically I'd recommend reading the GNOME HIG: http://developer.gnome.org/projects/gup/hig/ it's a very informative read. Obviously we have to use Win32 UI conventions at least at first, but there's a lot of generically good advice there. Well worth reading for anybody who is going to work on winecfg. thanks -mike

Re: Create DLL stub files in c:\windows\system

On Saturday 4 September 2004 14:25, Mike Hearn wrote: > Make apps that search for the DLL files directly happy by creating empty > files for each shipped library There are applications (eDonkey is one of them IIRC) that call LoadLibray() themselves on a number of DLLs. Could be that they do their own linking as part of some anti-debugging technique, I don't know, but it's perfectly legal for application to do that anyway. For these apps having empty DLL files will not be enough. I actually was able to fool the app by putting MinGW cross compiled Wine DLLs in the system directory until it needed kernel32.dll, which doesn't compile. I had to resort to a native win2k kernel32.dll to get it past this but this may still be a good alternative to your empty DLL files. -Hans

So I can redo >the patch with the calls :) Typically you use MultiByteToWideChar() for any input strings and then WideCharToMultiByte() for possible output strings. You can look at shlwapi/path.c and other files in there to see how this is usually done. Depending on the place where you do it, it might be preferable to use dynamically allocated buffers instead of using stack space as Wine is already using quite a lot of stack. Principle: WCHAR *textW; INT countW = MultiByteToWideChar(CP_ACP, 0, textA, -1, NULL, 0); if((textW = HeapAlloc(GetProcessHeap(), 0, countW * sizeof(WCHAR)))) { MultiByteToWideChar(CP_ACP, 0, textA, -1, textW, countW); /* Do the Widechar call */ HeapFree(GetProcessHeap(), 0, textW); } Rolf Kalbermatter

Using winelib in python module

D3D7: textures, mipmaps, DDSCAPS_COMPLEX
by andrejoh＠c2i.net 06 Sep '04

06 Sep '04

Hi! First some good news (for me at least): Cedega from CVS can now be used to play Anarchy Online! [1] To get this working, Marius Grigoriu had to implement support for DDSCAPS_COMPLEX in the Cedega code; this support seems to be lacking in Wine. I've had a look at the patch, and both the Cedega and Wine implementations -- they are quite similar, but do have some differences in the texture creation part. In particular, Cedega has a lot of additional code in create_texture, and the parts in Wine's version seems to reside in the function create_mipmaps in the Cedega file (dlls/ddraw/ddraw/main.c). As far as I've understood things, the Cedega DDraw code is under the AFPL license, and cannot be merged with the Wine LPGL code; thus I've not looked further into that (the changes seems to be related to cube map support). However, the patch from Marius is released under the X11 license, and can be applied to Wine with minor tweaking (due to support for compressed textures in the Wine code). Should this be applied to the Wine tree (depending on me having ported it correctly, of course)? For reference, I've included the related part from the original patch as well (see also [1]). Unfortunately, even with this patch, running AO under Wine crashes with some texture related code: First chance exception: divide by zero in 32-bit code (0x419c6d5c).

If one dose "grep -3 DRIVER_FindFromHDrvr wine/dlls/winmm/*", every other usage of DRIVER_FindFromHDrvr is like if ((lpDrv = DRIVER_FindFromHDrvr(hDrvr)) != NULL) Why should expecting a NULL return be wrong?

dlls/msvcrt/time.c picks up wrong CLOCKS_PER_SEC define
by Uwe Bonnes 06 Sep '04

06 Sep '04

Hallo, wine/include/msvcrt/time.h defines CLOCKS_PER_SEC conditionally: #ifndef CLOCKS_PER_SEC #define CLOCKS_PER_SEC 1000 #endif in wine/dlls/msvcrt/time.c, <time.h> is included and defines CLOCKS_PER_SEC unconditional before to 1000000l. So MSVCRT_clock returns a value 1000 times to high. How should this be fixed? Should wine/dlls/msvcrt/time.c do the define unconditional? Do we need to use a different define (e.g. MSVCRT_CLOCKS_PER_SEC) in MSVCRT_clock()?

I posted it as a bug at > http://bugs.winehq.org/show_bug.cgi?id=2385 . If you can add something > about the coding style I can fix it up and repost it for inclusion. A few things that jump out at me (not really reviewed the code itself): - No C++ // style comments, I'm afraid. They aren't portable enough. - Use HeapAlloc() over malloc(), as it says in the cheatsheet - Are you sure there is a debugstr_a?? I can't think what it would do, ANSI strings can just be printed by regular printf - You have to declare all the variables at the start of a block. Yes, it's a pain. Another C portability rule. So, can't do this: LPSTR foo = bar; StrCpyA(a, b); int i; They all have to go at the top. - Minor stylistic note: you can use strcpy rather than StrCpyA. But I doubt this was a problem. - Usually best to space stuff out, ie rather than this: if ( temp_out == temp_out2 ) { temp_in += 3; continue; } use this: if ( temp_out == temp_out2 ) { temp_in += 3; continue; } ... again I doubt Alexandre would reject the patch because of this. - //if ( *temp_in == '.' ) ... wine code generally doesn't do this. If you find it hard to match up a closing brace with the statement that opened it maybe you need ... *fanfare* EMACS! :) - Is it possible to implement the ANSI version by converting to unicode then calling the wide version, rather than duplicate it? The rest looks fine, I expect it was just the C portability stuff that tripped you up. Please do try again! thanks -mike

It was said many times already that the real fix for that bug is to move all user object management into wineserver and use the same handle allocation scheme as the one used for windows. -- Dmitry.

Possible fun project/todo list item?
by Mike Hearn 06 Sep '04

The OpenSSL library we use in wininet/netconnection.c is a very unstable library, with somewhat odd licensing as well. By unstable I'm talking about the interfaces it exports: unfortunately they break backwards compatibility very frequently with the result that a build of Wine compiled on one system may bail out when using SSL on another, as the soname/abi of OpenSSL it's looking for has changed *yet again*. This also means that some distros deliberately ship older versions and just backport security fixes, as upgrading OpenSSL to newer versions is quite painful. Fedora at least does this. If anybody is looking for work to do then, addressing this problem may be useful. Probably the best way forward is to talk to the GnuTLS people (http://www.gnu.org/software/gnutls/gnutls.html) and see if you can get written confirmation from them that they have a strong commitment to binary compatibility (at least, more than OpenSSL does). It also seems to be a fairly stable project: the new maintainer is more focussed on portability enhancements and a slow release cycle than making huge changes to the code. If so, it might be worth porting wininet over to GnuTLS, or alternatively, rather than remove the OpenSSL code just add code to use GnuTLS and then fall back to OpenSSL if it cannot be found (or vice-versa). One interesting thing about GnuTLS is that it has some OpenSSL compatibility code, but from a look at their website it seems that this is GPLd. Maybe we could get an exemption from them. The downside is that while OpenSSL is frequently going to not be found as it's the wrong version, GnuTLS is also not widely installed by default so it might not get us much in the short term. The good news is that Gaim packages are often built against it, so in any modern distro that packages Gaim (which is a very popular chat client) in its repositories, there's a good chance GnuTLS is packaged as well. thanks -mike

Re: Wine and industrial communication like OPC
by Rickard Svensson 06 Sep '04

Thank you, for all your answers! We have one employee who has worked a lot with Windows, and same with OPC. So I can provide same answers. * Mike Hearn - OPC is mostly used for data collection, and to a lesser degree to control industrial machines. * Juan Lang AND Robert Shearman - OPC doesn't use named pipes. OPC uses Dcom over TCP. * Mike Hearn - OPC doesn't need any new Windows (2000, XP) parts, and should work on Win 98 with the added Dcom support (not tested). * Mike Hearn - Price of OPC for Linux was when I looked at it for about a year ago 3000 - 4000$ per project you used their API in. And it only supported one of the OPC versions. Now I guess that the prices has been going down... Now I also got some questions from your answers: * Did I understand correctly. Wine doesn't have a built in support for DCom, to be abel to use Dcom I have to add the DCom support from Windows 98 to the Linux system? And the problem with that is the MS License, it stops me from distribute those XXX.dll with a Linux product (hardware and software in this case.) * We want to make a OPC server, because other computers want to get information from our system. Is there a problem in make a DCOM server, is it the "no user can acsas port under 1024 on a Linux system" problem. * What I have heard I thought DCom uset RPC??? But Juan Lang wrote that Wine doesn't have support for RPC /Rickard -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm

It's a problem for lots of reasons. They add up to this: this is unimplemented in Wine, and probably won't be implemented any time soon. > * What I have heard I thought DCom uset RPC??? But > Juan Lang wrote that Wine doesn't have support for > RPC Did I? I certainly didn't mean it. But you'd need to install the DCOM98 update to have any chance of success at it for now, at least if I read the code right. --Juan __________________________________ Do you Yahoo!?
