Have anyone tried, stress prime on ReactOS?

by Ashuaria Lee

Hi, Guys(and Girls) did you heard about a program called "stress prime"? It was developed to calculate prime numbers. And it is very sensitive to small errors. Since it has some kinda detecting errors, many overclockers are using it to confirm overclocked H/W stability. Yes, I tried to run this program, just for fun, and surprise! The system is not overclocked, nor has problem when running stressprime on WindowsXP. The rounding error amount was huge. I saw the source code of the stress prime and I'm sorry it was assembly language, so I couldn't check what could make such prolem under ReactOS. It was all about the math, and I'm not good at both(asm,math) But, one thing sure, is something is not working properly(maybe kernel?) and it is affecting ReactOS stability. What is your opinion? any comments? -- Regards, Ashuaria Lee

Hi, Alex Ionescu wrote: > You should always use memset and void HEAP_ZERO_MEMORY. Could you please tell why HEAP_ZERO_MEMORY should not be used? It is used in many places, so if something wrong with RtlAllocateHeap, maybe better to fix it? Thanks, Dmitry

You should always use memset and void HEAP_ZERO_MEMORY.

why IOCTL_DISK_GET_DRIVE_GEOMETRY_EX failed in windows 2000?

by Jack Yi

hi,guys: I don't know if it is proper to ask such a question here. I'm sorry if I break some rules. why IOCTL_DISK_GET_DRIVE_GEOMETRY_EX fail in windows 2000 and succeed in windows xp and greater version? or how can I get a disk(whatever,ATA,SCSI,USB )'s real size(including additional sectors) in a easy way in windows 2000, just like there is such a function, __int 64GetDiskRealSize(HANDLE hDisk); Could anybody help me? Waiting for reply. Thank you!

compatibility vs. correctness

by Matthias Kupfer

Hi folks, yesterday a user shows me a program what is working properly under windows, but not working under reactos. It was an open source program and it was easy to figure out the problem. It was an invalid win-api-call (wrong parameter value). Due to this situation I would like to ask one question. How compatible reactos should be? Even fault compatible?

I think this is like compiler warnings. Some checks are disabled by default as they would cause more harm than good. But there is an option to enable them. It will help to catch bugs in software.

ddk header cleanup

by Timo Kreuzer

Now that Stefan has cleaned up some stuff in the ddk headers, maybe we should think of some additional design fixes here. We currently have ntddk.h include "per version" headers: winxp.h, win2k.h, winnt4.h. These contain very few stuff. My suggestion is to merge them into winddk.h. We could also merge winddk.h and ntddk.h It might make sense to split wdm.h and ntddk.h into architecture specific files Layout suggestion: - ntddk.h: includes wdm.h and contains arch-independent definitions currently in winddk.h/win2k.h/winnt4.h - wdm.h: includes arch-dependent headers, contains arch-independend wdm definitions - ddk_x86.h / ddk_x64.h, ddk_arm.h, ddk_ppc.h / ddk_mips.h: arch-dependent definitions for both wdm.h and ntddk.h definitions (#ifdef _NTDDK_ ...) Comments appreciated. Timo

Hi Eric, Just wanted to tell you that your patch is correct and the Release Buildslave is failing as you can see from its log. For some reason, it stopped cleaning properly today and also has weird file deletion issues sometimes. But as long as the patch builds on the Debug slave, it's correct in 99% of all cases. Wanted to finish this mail before you reverted in r37802, but I was too slow. :-( So, it's safe for you to reapply r37801 and it's here to stay! Best regards, Colin
