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.

by Alex Ionescu

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

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!

by Merlyn Rees

Surely some things really could be split off into separate projects if people felt the urge without causing any real problems. This very ftp server, for instance, or a replacement shell (as in a new explorer.exe). The kind of projects that require more common application developer skills, rather than reproducing Windows internals. ...alright, so the appropriate shell hooks aren't in place at the moment. Bad example. Hopefully you kind of get what I'm referring to though. On May 15, 2009 7:41 PM, "Imre Leber" <imre.leber(a)telenet.be> wrote: Well that is exactly the reason why linux is broken.

Stubbing Block w TEB

by James Tabor

This should work! It's just writing zero into a place holder in TEB but it throws a exception and kills boot!

RosBE 1.4.2 available, update highly recommended!

by Colin Finck

Hi everybody, Daniel and I just released the new version 1.4.2 of the ReactOS Build Environment for Windows and Unix. The most important part of this release is the addition of some environment variables containing the include directories of the host and target compilers as compiler flags. These variables might be required by rbuild in the near future, so the update to the new version is highly recommended. Besides, the GCC in RosBE-Windows 1.4.2 is now compiled for i686 or later CPUs, decreasing the compilation time by 5 minutes for Daniel. Hopefully another reason to make the update more attractive ;-) As always, you can get the latest release from https://sourceforge.net/project/showfiles.php?group_id=6553 Best regards, Colin
