Wineserver semantics
by Waldek Hebisch 06 Mar '01

06 Mar '01

There is ongoing disscusion on how to seed up the wineserver. So I have question concerning correctness of corrent implementation. Namely, for reading or writing files I have not found any locking in wineserver when issuing file descriptor to clients. On the other hand the client closes file descriptor just after use, and also disscusion in the group suggests that client is supposed to have exclusive acces to file. So I would like to know what is the case: 1) client is allowd to cache the descriptor 2) current implementation depends on winning a race 3) I missed locking in wineserver -- Waldek Hebisch hebisch(a)math.uni.wroc.pl or hebisch(a)hera.math.uni.wroc.pl

WinCE/PocketWindows?
by Robert & Jennifer Hartley 06 Mar '01

06 Mar '01

Hi, (Please forgive me if this has already been examined, as this is my first post.) I am curious to know if a version of WINE has been considered that would be made to run WinCE (CE) and PocketWindows (PW) applications on Linux PDAs. I have been working with the Agenda VR3 PDA from www.agendacomputing that runs Linux very well on a MIPS processor. I also received a free set of Embedded Tools CDs from MicroSoft that have VC++ and VB on them for building CE and PW applications. The platforms it supports are X86, MIPS, ARM, and SH3, and I believe there are others. There is a compatability layer that runs on WinNT to test before deploying. If we had that emulated in Linux, then we would be most of the way towards being done. (Or so I would imagine.) Naturally, since I am a Linux/Unix guy, I was thinking that it would be neat to have these CE/PW apps running on my X86 Linux box, my NetWinder, my venerable old Indy, and finally, once debugged, on this Agenda Linux PDA. The WINE community has already done a huge amount of great work, so I thought that maybe a cut down version of WINE would work on the CE/PW subsets of Windows. Being an outsider, could someone let me know if I am totally out there in LaLa Land?

Re: Perl/Wine extension for perusal

Hello, Two small suggestions: 1. python has very good WIN32 bindings and also generic DLL interface CALLDLL. 2. VNC has alpha of macro recorder which can be used for interactive tests. Regards, Niki Spahiev

Re: RFC: client side implementation of async I/O

Your approach is not going to work with the latest changes I made to the server. The good news is that the changes I'm making are in part to allow making server calls in signal handlers, so when this works you should be able to use SIGIO to do async IO. > i think this implementation is more efficient, as it makes fewer server calls > and duplicates fewer file descriptors, while maintaining correctness. It's not clear to me that it is more efficient; it seems it will do a lot more work on every single server call if an async IO is pending. Of course the only way to tell is to run benchmarks. -- Alexandre Julliard julliard(a)winehq.com

TCP/IP networking and registry keys
by Alan Chandler 06 Mar '01

06 Mar '01

I spent most of the weekend trying to get Grand Prix Legends GPL to work. I achieved my first goal of getting it to run in server mode. One of the things I needed to get the game to do, was to recognise that there where some interfaces it could talk TCP/IP out of. It took me some time to realise that under windows it was doing this by looking for the key [System\\CurrentControlSet\\Services\\Class\\NetTrans] and was then enumerating the keys under it to establish an IP address ie the following [System\\CurrentControlSet\\Services\\Class\\NetTrans\\0000] "IPAddress"="10.0.10.100" The thought occurred to me that maybe the tool the builds the registry during wine install could actually create these keys - since it is essentially a key part of the system (and other similar keys are also built in the same way). I don't think I have the skills to do it myself yet. Alan alan(a)chandlerfamily.org.uk http://www.chandler.u-net.com

Wine Press
by Eric Pouech 05 Mar '01

http://linux.cnet.com/linux/0-2136864-7-4961586.html worth the reading, even if Wine gets the lowest ranking my reading of it is that Wine is not yet a product (compared to the two others). I definitively think we should focus more on a release target. It of course means that we have to make choices (do not include some functionnalities), spend pretty much more time on testing... but that's the way to go if we want to have Wine 1.0 around on of these days A+ --------------- Eric Pouech (http://perso.wanadoo.fr/eric.pouech/) "The future will be better tomorrow", Vice President Dan Quayle

Rather than hardcoding the paths into the code, could we do this instead: while (PROFILE_EnumWineIniString( "afmdirs", idx++, key, sizeof(key), value, sizeof(value))) PSDRV_ReadAFMDir(value); This has the added benefit of allowing the user to specify only those AFM directories that their rasterizer knows about too. With the above, I get a whole bunch of printer fonts listed as available in wine that I can't actually print if Ghostscript isn't configured to find the font files. -Gav -- Gavriel State, CEO TransGaming Technologies Inc. http://www.transgaming.com gav(a)transgaming.com

Thanks. Fixed patch attached. I did change left multiplicator from 2 to 4 in my earlier patches, but I forgot to include it in my final patch being 3 AM and so... I'll try to be more careful next time. Vedran

IMHO, for such loops the following would be much clearer: <init_expression>; while (<test_condition>) { <update_expression>; } (ok, you can also put '{' on the next line) > Please do the same for these for loops in the future. ??? > Somebody might want to write a Wine coding guidelines article... $ wg . -E 'for *$' | grep -E '$ *; *$'` | wc -l 96 (wg is my recursive source grep script) Maybe we should ask people to put the for and the instruction it applies to on separate lines.

RFC: client side implementation of async I/O
by Michael McCormack 04 Mar '01

04 Mar '01

Hi all, This patch moves responsibility for asynchronous I/O to the client process. i'm posting it to wine-devel because i want to know what other developers here think about the technique i've used to make this work... i've relaxed some of the assumptions wineserver makes about client processes. i think this implementation is more efficient, as it makes fewer server calls and duplicates fewer file descriptors, while maintaining correctness.
