It seems that other people, from the FreeDOS site, are already working on the idea of making the FreeDOS utilities working as console applications on windows. There seems to be already a sourceforge project created. But I don't want to anounce the work of somebody else too much. So I'll be quiet about the rest. Making them available as windows console applications is probably best, that way they can be used in windows, reactos and FreeDOS (using the HX-DOS extender), exactly the same. People can then choose wether they want to use/bundle these with reactos.

I would very much like to extend this maintenance into reactos. I actually would like to volunteer for all these other tools coming from FreeDOS too. But then we do talk about fully 32/64 bit binaries that are fully aware of reactos. You could build thess from scratch for the reactos project, but I think it would be much more productive to start from an already very stable code base. Instead of maybe again spending 12 years of development.

Command line

by Imre Leber

A few hours ago the base part of FreeDOS version 1 was released. Now is probably a good time to port all the relevant FreeDOS commands: move, diskcopy, diskcomp, chkdsk, fc, ... to reactos. Some of them are written in assembly and would inherently not be portable (deltree, ...). Imre

If dosfsck can be made to work reliably in reactos then FreeDOS chkdsk, which I wrote, should be portable to reactos, just by recompiling and rearanging some files. This is because i used the io.c file from dosfsck to port chkdsk to linux. And that also means that defrag can be recompiled the same way, since it is the same FAT manipulation code. Then only a windows interface would be needed! Actually i think I am going to add a method to defrag, that pretty much does what windows does (I think): move through the directories, and for every file that is fragmented, move it to a space where it can be store unfragmented. You could do this a number of times until a fixpoint is reached or a fixed number of times. And if you keep this up as long as defrag is running. You could build a defrag that automatically keeps all your files defragmented (as far as possible). If you want to do a full defragmentation then, maybe once a year, you would have to arrange it so that the drive became locked for the duration of the defragmentation.

Re: [ros-dev] scope?

by Imre Leber

Well, the reason I ask is that i am also maintaining a defrag utility. It currently does FAT12, FAT16, FAT32. But it would most likely not be so difficult to change it so that it can use the reactos calls for manipulating the file system. So it also works with NTFS. It has a lot more functionality then is available in windows defrag. Like sorting directories, which I think is not possible in windows. And 5 methods of defragmenting drives. A new interface should also be easy to add. There have always been two interfaces. So the all the file system manipulation code is completely seperate. The defragmentation code already works in windows xp, on image files, because that is how i debug it with visual C++ 7.1. So, you can tell me wether this would be of interest to reactos.

Further is there any specification that says for example "everything has to be compilable with mingw", or "everything has to run on i386/pentium xx"? Imre

Programs >inside the virtual DOS environment use illegal opcodes to talk to NTVDM. > FreeDOS works just fine in DOSemu. Actually that is how it got debugged by the kernel maintainer who was also the DOSemu maintainer. But no code of FreeDOS is actually special for DOSemu. The invalid opcode handler is probably similar to int e6 in DOSemu. It is an extra API by which DOS software can use services of DOSemu. What probably is needed is an implementation of the int 21 interface, and maybe others, in the V86 monitor. For what I understood from reading a litle on the web is that it more or less works like this: You have v86 code in the kernel. This can be mapped using memory paging to point to a certain address, where a DOS program is loaded. When an interupt occurs, the V86 mode is exited (the only way a V86 task can be exited) and the V86 monitor, in this case ntvdm takes over. This looks at the state of the interrupt and acts upon this. For example when calling an int 16 function it may return the status of a key. After the interrupt has been serviced the registers are loaded with the right values, or memory is filled correctly, or something like that and the v86 task is allowed to run until the next interrupt. Of course the software APIs can also be serviced by the V86 monitor and this is probably what is done in windows. ntvdm is special in that, unlike DOSemu, it serves as the V86 monitor for all the V86 tasks running in the session.

Re: [ros-dev] (Free)DOS subsystem

by Imre Leber

DOSemu has a 80386 emulator on board. Or at least in the sources. It doesn't seem to be in the DOSemu documentation so it seems that it is non-functional.

start

by Imre Leber

So, if nobody objects I guess i'll start porting DOSemu to reactos. After all, we need to start somewhere. And when this is done, it would be easier to talk about why it is or it is not a good replacement for ntvdm. Imre

(Free)DOS subsystem

by Imre Leber

Hi, I guess i am new to this list. I have been a maintainer on the FreeDOS project for more then 7 years. I have also noticed that you are still looking into building a DOS subsystem in reactos. After the release of FreeDOS version 1, I would like to see wether I could not take up the task to having it running under reactos. My main idea involves using a port of DOSemu. Is there any documentation regarding the running of a DOS subsystem in windows that I should study beforehand? Imre

Frist test of clipboard patch from SoC project

by Magnus Olsen

Hi I I got the clipboard patch from thomas and waiting on the final dectsions from him. Thomas need some time to review it. for it is around 121Kbytes big I did test it in ReactOS and I alot happy 1. Copy text and picture betwin program is working with this big patch 2. Copy file from one place to anyther working. But I wisch it show file copy when it doing it 3. copy file to the desktop does not working nug in explore ?? 4. move icon on the desktop is a new bug in win32k. 5. mark the text is white background with white text instead for invert background with white text 6. cut/copy/paste is working 7. keys like cut/copy/paste (ctrl+x,ctrl+c,ctrl+v) is working in all program I tested. say this patch is really good sussess and adding a clipboard to reactos. that working betwin program and u can copy/paste files and more I say it it is up to thomas to aprove the code. I have not looked at the code at, more that a fast preview.

GetSiteSidFromToken in advapi32

by Grzegorz Jaskiewicz

Hi folks based on my knowledge and some docs I used to read ages ago. Plus some recent googling, I kinda recreated function GetSiteSidFromToken from advapi32.dll - as it was missing there, and I couldn't start w2k taskmgr because of that. Of course simple stub returning NULL should be sufficient, but I gave it a shot and tried to implement it fresh and fully functional. First, I am not sure of few things there. And if someone is more knowledgable than I am - please let me know your thoughts. As far as I know the function returns pointer to SID from token. But there's more than one token. So it returns token that has "SITE" SID. Now, there were quite few SIDs missing in ROS, I tried to add them - mainly guessing their names based on some googling. Some docs on msdn say that they are all defined in ntseapi.h - but I couldn't found that file anywhere. For more details lookup attachment 1043 and corresponding bug. Function is quite simple, it iterates through all sids, trying to match the one with "SITE" authority. Question now arises - what if there's more than one such SID ? Does ROS use SIDs 1-6 to 1-8 at all ? is the SECURITY_INTERNETSITE_AUTHORITY the SITE authority or perhaps SECURITY_SITESERVER_AUTHORITY ? I don't know. I will try to write simple code that would ask original function from original dll about it, and see what it comes up with. First part of the code comes as simple c&p from other functions. The iteration is quite obvious. I didn't knew what should I use to compare SIDs, so I used memcmp. But perhaps simple comparing values in the table one by one would be simple, or maybe there's some sort of ROSish/NTish specific function that is more "right" than memcmp. Another question I have - is it normal practice that you alloc extra ram and return pointer to copy (seems to be in other places in your code), or should I just simply return pointer to the SID ? I do appreciate any comment. Patch is attached. if someone has the ntseapi.h file anywhere on their discs, I would like you to verify SECURITY_*_AUTHORITY names as well as values. I spent whole day gathering info, and I used all info I could find. Sorry for such long letter. Much too long I suppose. this is my first attempt to hack anything for ros. I promise next time I would try to take care of something more obvious and better documented. till than, ta. -- GJ
