Hi Martin:
Last time I saw it no I haven't checked in a while), but I guess my answer should be not yet since I have not seen any discussion about that on the list until now that you ask. If you want to be sure check ntdll (the interface is machine generated so you need to check the program that builds it, what I remember is that it generated an .asm, you can also check the asm after you build the system). Also the ROS build system needs sub architectures configurable to use this one since this instruction is PII+ hey I bet we all know we are missing a lot of great stuff only implemented in more recent processors, SYSCALL is only one of them. Another thing that could be done is to detect the CPU at some time during initialization and use one of two ntdll (on with SYSCALL an another without it). The question is: should an installed ReactOS resist a CPU downgrade? Probably yes but most of the times is just a waste.
regards
Waldo

Does ReactOS use optimized SYSCALL instruction on modern processors when
invoking kernel functions?

This patch works around the 'hanging after 2nd stage install' bug but I
don't really understand what's going on here. Basically, It looks like
ProcessData is null on the very last call (the one that would seemingly
flush the registry and reboot).
If i comment the break, nothing breaks and reactos reboots as expected
when i press the reboot button.

Hi,
I'm tired of fixing bugs in code ported from wine <x> years ago. In most
cases the bugs has already been fixed in the wine code we ripped from,
but the ros variant is forked so much its impossible to inc. those fixes
into ros, so the only choice is to rip the whole wine source over again,
loosing any possible fixes/improvements we had made to the ros variant
vs. the wine variant.
Take for example the file lib\kernel32\misc\profile.c. This file is
99.9% unchanged from wine, and only includes and some prototypes needed
changes. I want to move files like this into wine subdirs. like
lib\kernel32\misc\wine\profile.c and generate an initial diff
lib\kernel32\misc\wine\profile.diff with changes made to make it run on
ros using the wine porting headers. It does not mean that this diff will
contain ERR changed to DPRINT etc. Only the bare changes to make it
compile. Moving files into wine dirs in off course not necesary, but it
makes it clear that this file(s) are shared thus there are rules to
follow when changing them.
I have made scripts that updates our profile.c, using the profile.diff
and any updated profile.c from wine, and i have made a script for
generating patches that we send to wine. It all seems to work fine.
HELP: where does the winehq2ros.patch files used in comctl32 etc. fit
into this?
The only problem is wines strange unicode strings, their FIXME, ERR etc.
and indentation. I think its worth it if we can share more, but dunno if
the majority agrees.
From what i can see, much of kernel32 and ntdll can be shared this way,
and probably much stuff in user32/gdi32 also.

Gunnar

Nice fix Royce.
Keep it up!

Hello,
I got :
Current date: 2004-12-20
ROS Version : 0.3-CVS (Build 20041220)
rcopy.c: In function `copy_file':
rcopy.c:90: error: storage size of `ut_buffer' isn't known
rcopy.c:132: warning: implicit declaration of function `utime'
rcopy.c:90: warning: unused variable `ut_buffer'
make[1]: *** [rcopy] Error 1
make: *** [tools] Error 2

After reading a question on the forum, I decided to find out exactly what is
keeping Visual Basic programs from running and see if it's easy to fix. It
turns out that about the first thing that the VB runtime (msvbvm60.dll) does
is check the version number of the OS. At the moment we return:
dwMajorVersion = 4
dwMinorVersion = 0
dwBuildNumber = 0
dwPlatformId = 2
szCSDVersion = "ReactOS 0.2.5-CVS (Build 20041216)"
wServicePackMajor = 6
wServicePackMinor = 0
wSuiteMask = 0
wProductType = 0
The VB runtime wants at least NT4/SP3. The checks that currently fail are
dwBuildNumber (needs at least 1381) and the check for the service pack. It
expects the szCSDVersion field to be "Service Pack x" and extracts the
service pack number from that. (Good thing btw that there are not more than
10 service packs for NT4...).
Anyway, dwBuildNumber will have to be increased to 1381, that's no problem.
But the szCSDVersion is currently the only way for usermode programs to get
the ReactOS version. I know it's used by e.g. cmd.exe to display the version
number.
So, I don't think we have much choice, szCSDVersion will have to be set to
"Service Pack 6". Question is how to make the ReactOS version string
available. I've been thinking about adding it after the "Service Pack 6"
string (so the sp6 string is terminated with a nul byte, following the nul
byte is the ReactOS version string). Another option would be to store it in
the registry, but that would mean that it could get out of sync with the
version info in the kernel.
So, I'd like to store it as second string in szCSDVersion. Any objections to
that?

It will be faxed to you in 30.
