Hi Gunnar: Great! less duplicated code == better code I had planning to report this about msvcrt/crtdll the first chance I could get to read my e-mail, but now that you talked then there's no better chance than this I think. I was playing with msvcrt dll a couple of days ago because I was trying to test some apps against it and to maybe find some of the multithreading issues it contains. Well I dropped it because I really had no time but one thing I noticed is that there are some entries in the .def file something like this strlen=ntdll.strlen only strings routines if I remember well. Now after I got the binary file (.dll) I was inspecting it with LordPE, a tool to sniff every detail of PE's and saw that actually those routines are not imported by crtdll (maybe because of the strings.a statically linked) also I saw that msvcrt.dll is importing functions from itself funny that is something I never saw before (Is ROS parsing the exports table before the imports one? Just curious). But worst there are 2 references to msvcrt with different functions that the -O flag when passed to the linker can't fix. I have seen this before in some applications compiled with mingw (freecraft for example. Could be this an unnoticed bug in mingw's linker? If It is, it doesn't harm but it sucks to not have it the better way you can if it is easy to do it). btw I was also looking for string routines exported by ntdll in order to squeeze a bit more both libraries and noticed in XP's ntdll some functions that at the beginning I thought were mistyped (It would not be the first time) but when I took a look at msdn Tada! WindowsCE functions, nothing about XP/2k... but there they ARE. Please do not forget to fix those problems with exports if you can, or anyone with a chance, those libraries stink a lot. I still don't understand every detail on how the whole thing works: build system, linker... so this is a "I don't know how to fix", at least for now. Best Regards Waldo Alvarez ________________________________ From: ros-dev-bounces(a)reactos.com on behalf of Gunnar Dalsnes Sent: Wed 1/26/2005 8:19 PM To: ReactOS Development List Subject: [ros-dev] msvcrt/crtdll "merge" Hi, I'm currently "merging" msvcrt and crtdll (again). I'll move msvcrt into a library lib\crt and have msvcrt and crtdll link against it. Only dllmain.c will be left in msvcrt/crtdll. Most of (99.9%) crtdll will be dropped. It all seems to work nicely. One problem thou: I ran into some header problems, where i relied on some stuff in include\msvcrt\string.h but no matter what, mingw\include\string.h were included instead (and they both defined _STRING_H_). After looking at the headers in inlcude\msvcrt they all seem to be ripped from mingw. Does anyone know why they were put in include\msvcrt when mingw has headers for all of this stuff? Can i just remove them (include\msvcrt)? I looked at many depends files and saw most files depend on many mingw headers. Is this correct? Should we depend on mingw headers at all?

Calling all enthusiasts! Become a JANITOR (Just A Newbie Intensively Training On ReactOS) today!

by Alex Ionescu

Dear ReactOS enthusiasts and friends, We are currently in dire need of motivated people to help us build the future OS of the masses. While our developers are busily creating new code and fixing bugs, there remain dozens, if not more, of things to take care of in our tree and in our code. I would like to extend an open invitation to anyone interested on becoming a JANITOR (Just A Newbie Intensively Training On ReactOS). As a JANITOR, you will join a team of people, which, just like you, want to see ReactOS succeed and have some spare time to help. You do NOT need any coding experience! Most of the time, only simple word processing skills are needed. Janitorial jobs will include cleaning up comment headers, standardizing the debug system, alphabetizing code and organizing files, compiling a list of fixmes, checking for spelling mistakes, etc. These jobs will be custom tailored to your abilities, and there will be no time limits (but you must commit to doing the job). Also, JANITORs will have access to an online collaboration site where the current top-priority jobs are presented, and where they can commit to one of them. You can also share the workload and work in teams, or however you work best. A status system will be available to monitor the progression of jobs, and many more tools will become available. So don't delay, and join the JANITOR program today! Send me an e-mail at alex(a)relsoft.net with your name, e-mail and contact availabily (MSN, ICQ, IRC (preferred)). A real-time communication tool will be preferred, but I can acustom to people demanding exclusively e-mail contact (since the JANITOR Project Site will have most of the information). I know that many of you want to help but that the current state of the outdatedness of the website and documentation, as well as the general lack of directions are discouraging you. This will be a unique experience to leave your mark in ReactOS. Best regards, Alex Ionescu ReactOS JANITOR Program Manager NOTE to Devs: The JANITOR Program is fully the child of my brain and is a personal project, and will not use the ReactOS bandwidth, site, or other resources unless explicit permission and agreement is made by all developers. You will not need to do any additional task or handle anything more and this will not affect your workload in any way.

Re: [ros-diffs] [weiden] 13346: 1. fixed InbvPutPixels() to save theebx register which caused bootvid to crash when built withoptimizations

Hello, weiden(a)svn.reactos.com wrote: > 1. fixed InbvPutPixels() to save the ebx register which caused bootvid > to crash when built with optimizations You need to save the esi register too. ebx, esi, edi, and ebp are callee-saved registers in win32/x86.

multiboot.S patch in need of review, please

by Royce Mitchell III

I was in a strange mood and decided to try to implement something Alex wanted. I've done the leg-work on this, but need someone familiar with boot-up and particularly smp to review this patch. I do not have access to smp, and do not wish to break it. This patch implements the /3G switch from within multiboot.S, which is necessary in order to configure the page tables correctly. I noticed some code in _main() that was processing a 3G switch on the command-line, and I can't understand how it could possibly work because it's not readjusting the page tables, nor does it transition to the 0xC0000000 address space that I can see, so I don't think that code actually works. If it does, I'm glad to be proved wrong. The patch I've written makes an assumption that lowmem is available when application processors execute the code. I can't seem to figure out how or where the application processor(s) actually get told to start executing, so I don't know if this assumption is true. However, if it's not true, if someone could point me to the code that inits the application processors, I can configure them to pass the needed info via %ebp or something. Finally, I haven't actually tried booting this code. I wanted someone to review it first for obvious blunders, or to tell me, if necessary, that I've wasted my time ;) If I'm on the right track then, when I'm feeling motivated enough again, I will actually try booting it.

ROS crashes when installing vmware driver

I built Ros with ACPI=1 but the feature is not working (in real hardware) as the computer does not go into low power state . At boot the debug messages displayed are : DriverBase for acpi.sys : 9ce1300 Advanced Configuration and Power Interface Bus Driver ACPI: System firmware supports: +------------------------------------------------------------ | Sx states: +S0 +S1 -S2 -S3 +S4 +S5 +------------------------------------------------------------ What is the status of the ACPI feature ? Is it supported actually ? Best regards Gerard

Re: [ros-svn] [royce] 13345: allow oring multiple DebugPort values

by Gge

royce(a)svn.reactos.com wrote: > allow oring multiple DebugPort values > > > Updated files: > trunk/reactos/boot/freeldr/freeldr/debug.c > Hello Royce, A nice option would be to have the debug messages displayed in a "Debug" window . This will allows to redirect the debug messages to a file . How difficult is to implement this enhancement ? Regards Gerard

reactos.com this weekend

by Ge van Geldorp

Some urgent maintenance needs to be carried out on the electrical installation in the building that houses the reactos.com box. To perform this maintenance, power will be shutdown Friday night till Sunday morning. I will be moving reactos.com web- and mailservices to a fallback box. This should take place some time Friday. Switch back will be Sunday. The bandwidth capacity of the fallback box is much lower than that of the main box, so please don't plan on submitting stories to SlashDot this weekend... Gé van Geldorp.

msvcrt/crtdll "merge"

by Gunnar Dalsnes

Hi, I'm currently "merging" msvcrt and crtdll (again). I'll move msvcrt into a library lib\crt and have msvcrt and crtdll link against it. Only dllmain.c will be left in msvcrt/crtdll. Most of (99.9%) crtdll will be dropped. It all seems to work nicely. One problem thou: I ran into some header problems, where i relied on some stuff in include\msvcrt\string.h but no matter what, mingw\include\string.h were included instead (and they both defined _STRING_H_). After looking at the headers in inlcude\msvcrt they all seem to be ripped from mingw. Does anyone know why they were put in include\msvcrt when mingw has headers for all of this stuff? Can i just remove them (include\msvcrt)? I looked at many depends files and saw most files depend on many mingw headers. Is this correct? Should we depend on mingw headers at all? Gunnar

videoprt.nostrip.sys

by Ge van Geldorp

It seems videoprt.nostrip.sys is somewhat messed up. I've attached the output of "objdump -p videoprt.nostrip.sys". Data Directory Entry 1 says there's an import directory at 0x0000b000. Then down under "PE File Base Relocations (interpreted .reloc section contents)" we find: Virtual Address: 0000b000 Chunk size 12 (0xc) Number of fixups 2 reloc 0 offset 14 [b014] HIGHLOW reloc 1 offset 20 [b020] HIGHLOW When the module is loaded, the relocations are applied. This messes up the import table, with the result that the module fails to load (copy videoprt.nostrip.sys to \reactos\system32\drivers\videoprt.sys and boot ReactOS). The 2 relocations given above are not present in the "normal" videoprt.sys module. I'm inclined to blame gcc (I'm using 3.4.1) or more likely binutils (2.15.90 20040222) for this, but before I make Filip unhappy, does anyone know if we're doing something wrong during the build process?

Re: [ros-svn] [ion] 13305: Dynamic 3GB support, part 1. Only multiboot.S remains to be changed, all other parts of the Kernel now used KERNEL_BASE based on the command-line (Please don't use /3gb if you don't compile 3GB)

We've got the plan set-up in our minds and it should be committed in less then a week, unless unexpected things happen. Speaking of which, is anyone against not making ACPI a compile-time instruction? It just makes debugging harder, one more thing to worry about, and I don't see the point either...I think it makes much more sense to have some kind of ACPISupported global variable that we either set at boot-up with proper table queries, and/or that the user can specify with an /ACPI command-line flag.

Slab cache

by Hartmut Birr

Hi, do we need the slab cache in ntoskrnl\mm\slab.c? I've replaced the kmap functions (ntoskrnl\mm\kmap.c) by a process local mapping (hyperspace). The slab cache needs the mapping for a longer time and cannot use the hyperspace mapping. I would remove the slab cache, because it is not used by any of the kernel functions. - Hartmut

user mode exceptions

by Hartmut Birr

Hi, on a user mode exception, I get hundreds of lines like this: (i386/exception.c:96) RtlpDispatchException() Dumping exception registrations: (0x0065FFE0) HANDLER (0x7C82CEAF) (0x7FFDF000) HANDLER (0x00000000) (i386/exception.c:96) RtlpDispatchException() Dumping exception registrations: (0x0065FFE0) HANDLER (0x7C82CEAF) (0x7FFDF000) HANDLER (0x00000000) (i386/exception.c:96) RtlpDispatchException() Dumping exception registrations: It needs a very large time, if ros does response again. It occurs on real hardware. Debugprints are going over a serial line. - Hartmut

But we use them on each directory except the root. The index from fcb is also used to update the entry of a file in its parent directory. For looking for a directory, '.' has index 0, '..' has index 1 and 'foo' has index 2 and so on. The real index of 'foo' is 0. We must make a difference between the real and the search index. I've modified some parts of freeldr and usetup. I can create and install ros on a fatx partition on a normal pc. I've also load vfatfs on W2K. At the beginning, the wrong index has scrambled the fatx partition. - Hartmut

And do you describe a program that CERT advises people not to use as "works"? But lets not argue over this. My reason for posting my commments is simply because I think some of us are only aiming at implementing a clone whereas I feel we should be striving to create a compatible OS that is even better, and I get the impression from the faq on the wiki site that was one of the reasons for this project's existence. But on the other hand that risks becoming bogged down in discussion about how things should be done. If at the end of the day we end up with nothing more than an open source clone of Windows that I can hack on I will still be happy.

One of the reasons Windows has problems with malware is because of developers going about things the wrong way. They need to be taught to do things correctly, not accommodated for.

memory leakage

by Hartmut Birr

Hi, since some days ros eats up paged pool memory. I'm using cmd as login shell. 'Make clean' on the ros source tree increase the number of paged pool pages from 500 to more than 8000. In the past the number of paged pool pages has never changed. - Hartmut

Booting with NOGUIBOOT gets ros to the installation page, where 2) Default selections for radio buttons and combobox do not appear, they must now be selected manually Apart from this glitch, driver installation and second boot were perfect, minus the following: 3) Debug message about unhandled exception, followed by an explorer crash related to a header file. 4) Browsing some registry keys in regedit causes regedit to crash. I haven't noted any other problems for now, but I haven't done any deep testing. On the up side, this brings my little syscall benchmark to 170ms, an additional 15% improvement. In total, this is an 80% improvement over int2e builds. Furthermore, all of ReactOS is extremly fast. Directory listing in cmd.exe is instant, explorer navigation as well. Menus re-draw instantly and the whole experience is smooth. It really feels like Windows, you have to try it to believe it. There's been some talk on activating OPTIMIZED = 1 if (K)DBG != 1 and all the developers on IRC were in agreement. But before such a change is made, the bugs above need to be fixed, as well as any other possible things which might crop up. Best regards, Alex Ionescu
