Win32/Gdi32 Rewrite
by jimtabor 18 May '07

18 May '07

Hi all, On or about September 2006 I was asked by Aleksey (PC) and Alex if I could head up the win32 and gdi32 part of the rewrite. The discussion had taken place on irc. It was important that the rewrite would have one developer working alone (preferred method) or be the leading developer working with a small group of developers (no more than three). The rewrite was needed so that this section of ReactOS would be compatible with the new kernel and the very thing we are trying to do. Be compatible. This included interfaces, structures and the data that was contained in those structures. Just not only that, also dropping in the place of drivers and dlls, the real thing and still be compatible. Yes! Running with ReactOS. I do not recall any requirement for me to write a technical manual or any kind of web wiki. Even a How-To-Black-Box an OS interrupt calling hooky thingy with kmtest driver callback winpooch as an application interface. ReactOS developers should have a healthy tool box. This point on, the discussion is over. I have a job to do. I would like help and not debate everything I do. Some of you, need to, really think about, the future of this project. How can I help with this and how can I help make this work for compatibility with the very thing we are working toward. If you are thinking about something new and different other than something innovative, compatible and helpful? Maybe this project is not for you. Aros, FreeMint, Linux, Syllable, Visopsys, X, etc, these projects might be what you are looking for. If it breaks compatibility with interfaces and data stored in structures? I will reject it and post an email why it was rejected. Wine is not enough, okay? Thanks, James

It should probably be + Exp -= (1 - EXCESS); in EFtoF() and + Exp += (1 - EXCESS); in FtoEF(). The other way round. Suggestion to make it a little clearer: #define BIAS 127 Exp -+= (BIAS - 2); jimtabor wrote: > --- trunk/reactos/dll/win32/gdi32/objects/painting.c 2006/12/28 22:36:53 25235 > +++ trunk/reactos/dll/win32/gdi32/objects/painting.c 2007/05/14 03:18:42 26772 > @@ -1,15 +1,66 @@ > [...] > +/* the following deal with IEEE single-precision numbers */ > +#define EXCESS 126L > +#define SIGNBIT 0x80000000L > +#define SIGN(fp) ((fp) & SIGNBIT) > +#define EXP(fp) (((fp) >> 23L) & 0xFF) > +#define MANT(fp) ((fp) & 0x7FFFFFL) > +#define PACK(s,e,m) ((s) | ((e) << 23L) | (m)) > [...] > +LONG > +FASTCALL > +EFtoF( EFLOAT_S * efp) > +{ > + long Mant, Exp, Sign = 0; > + > + if (!efp->lMant) return 0; > + > + Mant = efp->lMant; > + Exp = efp->lExp; > + Sign = SIGN(Mant); > + > +//// M$ storage emulation > + Mant = ((Mant & 0x3fffffff) >> 7); > + Exp += (1 - EXCESS); > +//// > + Mant = MANT(Mant); > + return PACK(Sign, Exp, Mant); > +} > + > +VOID > +FASTCALL > +FtoEF( EFLOAT_S * efp, FLOATL f) > +{ > + long Mant, Exp; > + gxf_long worker; > + > +#ifdef _X86_ > + worker.l = f; // It's a float stored in a long. > +#else > + worker.f = f; > +#endif > + > + Exp = EXP(worker.l); > + Mant = MANT(worker.l); > + > +//// M$ storage emulation > + Mant = ((Mant << 7) | 0x40000000 | SIGN(worker.l)); > + Exp -= (1 - EXCESS); > +//// > + efp->lMant = Mant; > + efp->lExp = Exp; > +} >

Re: [ros-dev] Bug into log10 function.
by carlo.bramix 16 May '07

16 May '07

Unfortunately, I just tested it into the latest working SVN build under QEMU (livecd-26665-rel) and this bug it is still into the CRT library. I also read the source code with SVN-WEB and it's still the same of 0.3.1. BTW, from livecd-26771-rel, a bad thing happens with QEMU: immediately after starting the boot, a blu screen appear with errors and everything is dead. Sincerely, Carlo Bramini ---------- This bug have already been fixed by me. log time ago. some time after 0.3.1 was relase or under 0.3.1 release process. plese use svn source code, and try make own build of reactos as well. the trunk is changes so fast, the code in 0.3.1 is already outdated in many areas.

Sorry net split on irc. Physicus r26742 is right,,, I will change it this week once I have the rest of my changes ready. We should support 0x00010000 - 1 = 0xffff handles and it will give us 65K. Thanks James

Differences in Windows and Linux builds
by Colin Finck 12 May '07

12 May '07

Hello, After the latest Kernel changes, I noticed some differences in ReactOS builds compiled under Windows (RosBE 0.3.4) and under Linux (BuildBot and my 32-bit Ubuntu system): - At the boot screen, the version compiled under Windows shows "Service Pack 1" correctly, but the version compiled under Linux shows "Service Pac 1" - The version compiled under Linux hangs at "Flushing cache" for me, when I test it under VMware. Some other users also wrote that they could not run the latest ReactOS builds under QEMU. Although, I could not reproduce this problem with r26719, it might be related to these build differences. As I don't know, where this problem might originate from, maybe someone else could look at it. Regards, Colin

Re: [ros-dev] QEMU support broken!!!

Sorry, but before writing this messages I tested *ALL* SVN releases from livecd-26660-rel.7z to livecd-26672-rel.7z (except livecd-26671-rel.7z). I also tested livecd-26626-rel.7z and livecd-26650-rel.7z and they both worked (when I saw that livecd-26670-rel didn't work, I started with checking something older...). Here the last working version is still livecd-26665-rel.iso.
