msafd headers

by Mikhail Y. Zvyozdochkin

Hi All! Files on reactos/lib/msafd/misc/ uses header "msafd.h" from reactos/lib/msafd/. On my system, MinGW/linux successfully compiled these files ONLY after I manually corrected include directive: #include <../msafd.h> instead #include <msafd.h> in all 5 *.c files in reactos/lib/msafd/misc/. Maybe we must make this replacement in svn tree? Or it was my misconfiguration? ;) WBR, DarkHobbit

Testing ROS on VMWare With 32MB... Interesting Results

by TwoTailedFox

Been having a poke around, it seems neither LiveCD nor BootCD will boot into GUI (Using latest HEAD SVN), on 32MB. BootCD will complete first stage installer, but won't boot into GUI to load the second stage setup. LiveCD immediately hangs. Now, on VMWare, I use Other/Other as the OS Category, and I've been hearing some (like WaxDragon), using Windows XP Professional as the OS Category. I obtained a BootCD of 17751 rev, and tried it on the WinXP setting, using 32MB. First time I tried it, it hung at copying ole32.dll (34%). Second time, I got a STOP error during the file transfer. Third time, however, it completed the first stage fine. The only difference between the Other and WinXP Pro settings is the inclusion of a USB Controller. I added one to my "Other" setup, and ROS, again, installed fine first time around on 32MB. Now, for the interesting bit. The error is a pretty constant one, and it complains of No Memory Pages Available. It seems just common to the GUI, seeing as ROS won't boot on 32MB even once Setup is completed. This is the case for both SVN Live and BootCD's. Something in the GUI is causing a leak -- "I had a handle on life, but then it broke"

NamedPipes - cause massive reliability problems with services. what to _do_?

by Luke Kenneth Casson Leighton

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ipc/base/m… please note the comments "it is possible for a client to connect in between the CreateNamedPipe and ConnectPipe". in other words, NamedPipes don't have any equivalent of "listen()". this is a massive _massive_ problem, evidence of which i first encountered with "rpctorture --processes=100 --repeat-operation=100", back in 1998. out of 10,000 operations performed across 100 processes, about TWENTY of those operations would succeed. that's a success rate of 0.2%. (anyone who runs a lab where 400 students sit down at the beginning of a session and all log in to the same NT PDC will tell you _exactly_ what they bloody think of windows and it's the same issue) the reason why there is such an abysmal failure rate was not clear to me until today. it's due - quite simply - to this delay. if the server is particularly overloaded (due to having to deal with, oh i dunno, say, a large influx of incoming Named Pipe client requests) then the time delay between CreateNamedPipe and ConnectPipe is increased; if some idiot decides that the number of pipe connections is to be limited; if someone decides that the number of threads is to be limited, then the server quickly goes into meltdown. if there is protocol proxying or authentication going on (as is the case of SMB IPC$ providing MSRPC named pipes - ncacn_np for those people who know what that is) then you _really_ are in trouble. the question is: having access to the source code - in reactos - what can be _done_ about this? would it be reasonable to write - and use - a named pipes equivalent of "listen()"? alternatively, how in hell's name do you _deal_ with this sort of thing? l. -- -- <a href="http://lkcl.net">http://lkcl.net</a> --

Cant Install Self Compiled ISO

by Brandon Turner

I can't install any bootcd's that I compile, gives INACCESSIBLE_BOOT_DEVICE. This happens in Qemu, vmware, and virtual pc. I have done full clean builds by doing "make clean" and deleting the object/output folders. I don't know when this started happening really. But if i download the ISO off of CIA then its fine, the exact same version. I am compiling on Windows XP with ROSBe. Here is a link to a picture of the crash: www.brandonturner.org/crash.PNG Please help, its driving me crazy! Brandon

Binutils

by Casper Hornstrup

It seems that as of revision 17811, GNU ld version 2.15.90 20040222 is too old. Upgrade your binutils if you have that version. Casper

MC problem

by Hartmut Birr

Hi, if I compile MC (midnight commander ) with the option '-mpreferred-stack-boundary=2', the build-in editor doesn't work. MC hangs after pressing F4. This occurs on winXP and ROS. I've no problem without this option. - Hartmut

Kernel-mode COM required for Kernel Streaming (ks.sys)

by Andrew "Silver Blade" Greenwood

This is the most ugliest beast I've come across. Trying to implement parts of the Kernel Streaming (ks) stuff. I decided to start with portcls.sys. So far, it appears ks.h (the Kernel Streaming main header) isn't present in our include files (or w32api) and the official MS DDK version is 100KB + so that's a bit of a knock-out already. Anyway I had a poke around and stubbed a lot of the main portcls.sys functions. But I have no idea what I'm doing right now so it's pointless me trying. It appears to be built on COM - the MSDN documents describe "Kernel-mode COM" in the Audio and Video section. Obviously the standard COM calls can't be used in kernel-mode. And I found in kcom.h some declarations for functions such as KoCreateInstance (kernel mode version of CoCreateInstance?) yet I cannot find any references to it on Google. The sample drivers are written in C++, and appear to rely on kcom.h's C++ classes to get things done. There's just not a lot I can do as the foundation isn't even there for me to start implementing Kernel Streaming. And I have *no* idea how to use COM. So far it looks really really ugly. Can someone give me a hand? -Andrew
