The end goal with all of this is a ReactOS deployment system from a single image that can provision ReactOS thinkclients/diskless workstations without the need of a Linux or Windows host. Pushing out a freeldr or grub+freeldr or even pxelinux+grub+freeldr image with a blob containing a ROS ramdisk should be pretty simple using isc-dhcpd/tftp on Linux but I'm more interested in the infrastructure side of things right now. Currently the dhcpd with PXE support is the only part we are really missing. We COULD do it from Linux or Windows right now, but I want to get all the infrastructure in place where we don't need any other OS.

runtime time function question in freeldr

by Zhang Fan

Hi everybody, I'm a newbie of ReactOS, and I've just looked a piece of code in freeldr module. I found some runtime function such as strstr(). I want to know if the run time lib should be initialized, and where the initialized code. Another question is that a piece of code in arch.S EXTERN(RealEntryPoint) //.... .code32 /* Zero BootDrive and BootPartition */ xorl %eax,%eax movl %eax,(_BootDrive) movl %eax,(_BootPartition) /* Store the boot drive */ movb %dl,(_BootDrive) /* Store the boot partition */ movb %dh,(_BootPartition) /* GO! */ pushl %eax call _BootMain At there, I think %eax should equal zero, and BootMain will call CmdLineParse(),and CmdLineParse will call strstr(). So it cause strstr will receive a NULL parameter. Is it right? Thank you. Fan Zhang

Re: [ros-dev] [ros-diffs] [tkreuzer] 40963: MmGrowKernelStack: Don't assert, but fail, when the kernel stack can't grow any more. Fixes a crash with recursive user calls. See issue #4060 for more details.

The code SHOULD assert. This is a hack.

I want to develop the kernel of ReactOS, how do i join????

by Joshua Bailey

Hello mailing list folks! While Xiaoming wouldn't be able to have commit access, would he be able to contribute in other ways not related to coding, i.e., hardware or software testing? Just curious. Mr. Ionescu, I probably would have tried to tell Xiaoming what I know about the rules, too, even though I'm not a developer. Actually, the FAQ is pretty clear in regards to ReactOS only using clean-room reverse engineering. http://www.reactos.org/en/about_userfaq.html. I would have just referred him to this, if you or another developer hadn't jumped in to give a more precise answer. I usually leave it up to the devs to answer questions, but I try to answer questions if I can when no developer is at hand at the moment. I hope that doesn't mean I have a drug problem. :) To be honest, I was pretty confused myself about who could do what if they had seen Windows source code beforehand. I know the current position is that seeing source code != no ReactOS programming for you, but then again there was the whole debate a few years back about whether the devs at the top had seen any Windows source code and I'm still not sure how that got resolved. I had alternately heard that people who had seen source code couldn't contribute, or if they had they could only code stuff whose Windows equivalents they hadn't seen the source code to, so it's not something that was just made up. I'm not trying to restart old flame wars, but the fact is that the policy regarding Windows source code hasn't always been so clear, which may have left some people (myself included) confused. While I personally wouldn't have replied assuming the same level of authority as a developer, I don't think us ordinary folks should be blamed if we've gotten a little confused about this througout the course of the past few years. I don't mean to start off here on a bad note, but I get irritated because on the forums someone asks a simple question, someone answers, the devs get angry because they feel someone overstepped their authority, even thought the devs tend to give a terse answer with no explanation. The newbie scared of asking anything else about the project because folks get so angry with one another, and figures it's not worth the trouble of getting involved. By the way, if the formatting here looks like it was written by a crackhead, it's because this is my first time posting on the mailing list. (I'm more active on the forums.) Then again, my hometown inspired The Wire, so who knows. :P -Joshua Bailey

Re: [ros-dev] [ros-diffs] [fireball] 40961: - Initialize IoCountOperations variable to FALSE by default. Spotted by Dmitry Chapyshev & winetests.

Um, there's a serious compiler/linker/loader bug if that value is not already FALSE by default.

Firefox 3 too slow, i think due to log flooding

by Javier Agustìn Fernàndez Arroyo

hi devs, testing FF3 i have noticed that this app has been slowed down a lot And there is a high difference between running it with kdbg enabled, and running without it Also, log is flooded with the following lines: (subsystems/win32/win32k/objects/gdiobj.c:814) Attempted to lock object 0x0 of wrong type (Handle: 0x0, requested: 0x40000) (subsystems/win32/win32k/objects/gdiobj.c:814) Attempted to lock object 0x0 of wrong type (Handle: 0x0, requested: 0x40000) (subsystems/win32/win32k/objects/region.c:2250) NtGdiCombineRgn requires hSrc2 != NULL for combine mode 1!
