Re: [ros-dev] [ros-diffs] [tkreuzer] 44052: [NDK] - Add KEXCEPTION_FRAME offsets

by Alex Ionescu

Did you make sure these matched the actual Microsoft-defined offsets in ksamd64?

Reactos and MinWin

by Gerard Murphy

I've recently been taking an interest in MinWin, especially as it's now visible in Windows 7, and I want to bring up the possibility of introducing something similar into ReactOS. I know some of you will be familiar with WinWin and I know at least one of you will know quite a bit more about it than I do, but for those who don't here's an overview. What is WinMin? MinWin is an internal project at Microsoft that manifested around the time of the Vista rewrite. Very basically explained, the aim is to detangle the very core components from the full operating system, resulting in something which can be built separately and leaving just enough components for a working system. This minimal operating system can then boot and be tested separately or be built as part of the full OS and tested in internally as before. The main problem in doing this, and one of the main benefits in solving it, is module dependencies. By simply cutting out the bottom part of the OS you're left with modules which potentially call out to other modules which may now be missing. If these dependencies aren't understood you have the possibility of an unstable OS as you never know where a code path may lead. It also means you need to build more components to get the thing to link, which also undermines one of the reasons for doing it. What Microsoft did is to draw up a dependency tree and structure it in a layered hierarchy. Modules were then rearranged to make architectural sense according to the NT design and a top layer was decided upon. API call were then rewritten within this hierarchy such that anything in one layer would only call API's in the layers below it. Therefore if something in layer 8 called something in layer 7 which then called something in layer 12, the APIs would be fixed to only use APIs at or below its level according to the hierarchy. You're then left with a clean line where nothing calls out and you have a tightly bound core OS which is completely independent from anything. What is essentially left in Microsoft's WinMin is what people class as Cutlers NT along with supporting components to get a bootable system. The main components are: The kernel (main kernel, not the full ntoskrnl module), parts of the executive, memory manager, networking, a file system driver and core drivers (basc IO and Bus, etc) This is then exposed in usermode by 2 dlls, ntdll.dll and the new kernelbase.dll. On top of this you have a console for issuing commands. This comprises of the full OS and amounts to about 25Mb on disk and has around a 40Mb working set. Let's quickly explain the new kernelbase dll. As many of the API's in the lower level dlls such as kernel32 and advapi32 were targeting functionality which wasn't in WinMin, it was decided to pull out any of the API's which were required to exercise WinMin and put them into kernelbase. This dll could then be used when building a running WinMin to provide all the functionality this kernel offered. The dlls which had their APIs removed now forwarded their call onto kernelbase so from a user perspective, nothing had changed. Microsoft went a step further and designed a new technology around virtual dlls. They split functionality of dlls into 'api sets' These can now be seen in Win 7 in the system32 dir with the prefix 'api-ms-win-core-<function>-<num of>-1-0.dll'. WinMin components now link against these virtual dlls which load up the real libs listed in apisetschema.dll. However this involves modification to the loader and I don't think it's something worth us considering right now. What are the reasons for doing this? For a start, it's a much better design from an engineering perspective. The more software you have running on a system the more noise is created and the more things can interfere with each other. It gives us a base to innovate with without worrying about affecting anything outside. It gives us a more reliable base for the OS and a better platform to run comprehensive and efficient tests. It makes us more attractive to external companies as we would have a slick NT compatible kernel ready for companies to build their products on, especially embedded applications. With a few more additional items such as the base win32 subsystem, we'd have something along the lines of a stripped out ServerCore or Windows PE. This is only a quick overview for discussion purposes, but it outlines the main design and goals of WinMin. Comments, questions, concerns and gripes welcome J Ged.

0.3.11 Status update

by Aleksey Bragin

Hello, updating everyone on the 0.3.11 status. There is one blocker bug, http://www.reactos.org/bugzilla/ show_bug.cgi?id=4934, which is rapps's inability to complete any download in VMWare. Other regressions (including VMWare video driver, samba-TNG problm) are also present, however they could be either hacked away for release or shipped - e.g. not much of a problem since VMWare Video Driver installer doesn't work in new VMWares anyway. Amount of positive changes outweighs the negative. Please try to have a look at the 4934 bug to fix it ASAP. WBR, Aleskey Bragin.

Integration of ultracopier to reactOS

by alpha_one_x86

Hello, I'm the developper of ultracopier, I propose ultracopier as default copier under reactOS for the reactOS explorer. I will activly developpe it under reactOS. It based on Qt. Only the version 0.2.0.0 is developped for reactOS.

Booting via "ReactOS (Debug)" is broken - when trying to select it, it jumps back to the first item in the list.

Using alternative compilers to build ReactOS...

by King InuYasha

Hello, I had noticed that some of the developers are working pretty vigorously to get off of requiring GCC. I don't pretend to understand what that is about, and I honestly would like to know.. However, I just wanted to list a couple of alternative open source C/C++ compilers that could probably be used with ReactOS. Of course, what do I know, I'm just a newbie at being a C++ programmer... Anyway, the two compilers are: * OpenWatcom ( http://openwatcom.org/index.php/Main_Page ) * LLVM 2.6 w/clang ( http://llvm.org/ )
