Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Scratch that. I just took a look at http://www.opensource.apple.com/ darwinsource/10.4.6.x86/ and it looks like it was everything except xnu. I would wonder if this is a long-term problem or a short-term delay due to the kernel being under extremely active development. The general consensus seems to be that the reason is so that a hacker wouldn't be able to port OS X to a non-Apple Intel Box, but if this is the case, I would think there would be better ways to protect Apple's control. Specifically, Apple already ships a very important and always closed source aspect of OS X: "the GUI" (ie: the Window manager etc). Wouldn't it make more sense to tie this already-closed code to Apple-specific hardware through various hardware checks, and then allow the kernel to be open? This way, the most this "hacker" would be able to get running on any x86 box would be Darwin (something it has done for some time), but this same hacker wouldn't be able to get the GUI to run. I know the purists would say that this goes against general practice that all hardware-specific code should live in the kernel (and I agree in principle), but there must be some way to preserve Apple's control over their OS while also allowing developers to build new kernels. So I guess the question is whether or not this general consensus is correct or that is is simply that there is a short-term delay as Apple gets its collective act together. I'm sure for the most part, people on this list aren't much into the "popular press", but it seems there was a post on MacCentral this morning that may be of interest to folks on this list. Example Statement: "Thanks to pirates, or rather the fear of them, the Intel edition of Apple’s OS X is now a proprietary operating system. Mac developers and power users no longer have the freedom to alter, rebuild, and replace the OS X kernel from source code. Stripped of openness, it no longer possesses the quality that elevated Linux to its status as the second most popular commercial OS." Perhaps people here may want to comment. Admittedly, I'm a lurker more then a kernel hacker, but I thought this was addressed weeks/ months ago with the recent release of the source of the kernel for Intel.

The Intel kernel sources have never been released. Or at least there is no xnu in the 10.4.{4,5,6}.x86 download pages at http://www.opensource.apple.com/darwinsource/ // Christian Brunschen _______________________________________________ Do not post admin requests to the list.

There's nothing 'official' about that opinion post on Macworld - it's one guy's opinion. True, you can't get the xnu project for Mac OS X 10.4 Tiger for x86; however, there may be other reasons for that than Apple deciding to close the source code. If Apple _had_ decided, I would have expected them to also pull the source code for xnu on PC, yet that is still available. My personal conjecture/speculation/wishful thinking is that the current Mac OS X 10.4.6 / Darwin 8.6 xnu for x86 source code is not in a state where Apple want to release it, and that they are working on releasing a unified Mac OS X 10.5.0 / Darwin 9.0 xnu for PPC & x86 in its stead. I.e., they managed to get 10.4 working on x86, but it possibly includes some hacks they don't want to show the world; these hacks won't be necessary in the unified 10.5 code. Again, this is my speculation, but I think it is at least similarly plausible as the 'the sky is falling' conjecture from the Macworld opinion post.

Darwin PCC Coder out there? Where can I download the newest Darwin work?
by thomasoft 17 May '06

17 May '06

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Hi there I'm new here. I just wanted to ask if there are programmers out there who are working yet on the darwin code for ppc (G5)? 1. Can the newest Code somewhere be downloaded and installed to an actual MacOS X installation? 2. Or will the code only be given out by Apple itself? (I mean: do the coders the work and send the sourcecode to apple?) 3. Or does a website exist where all recoded Darwin versions can be downloaded? I hope you understand my questions...I believe there are some great coder talents ou there to boost OS-X' performance...

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com i answered you but my e-mail was refused from your pop ... sorry, missed filling in the subject, in my previous mail. "Puthali H.B" <bputtali(a)novell.com> 5/16/2006 10:58 am >>> hi, Don't know if this is the right list to post this query, but saw some threads already on overriding system calls, so thought will try my luck here. :) Actually I've a dynamic library which over-rides system calls, namely connect,recv,send,sendto,accept... and when I preload this on Tiger, using DYLD_INSERT_LIBRARIES AND DYLD_FORCE_FLAT_NAMESPACE, everything works fine. But when I do the same on panther, it crashes. I wrote a sample c test program, just over-riding connect call and compiled it as test_connect.dylib on panther, with gcc 3.3. When I pre-loaded this library in terminal and ran FTP got the following error- dyld: FTP multiple definitions of symbol _connect test_connect.dylib(ccyRQhrn.o) definition of _connect /usr/lib/libSystem.B.dylib(connect.So) definition of _connect Trace/BPT trap But the same dylib works perfectly on tiger. So I wanted to know, if I've missed out on any steps that needed to be done in addition on panther? i.e. is over-riding system calls possible on panther? If so any pointers in that direction will be appreciated very much. plus, am interested in knowing what are da major differences between panther and tiger regarding dynamic handling? can someone give me good links regarding this? :) thanking in advance, Puthali _______________________________________________ Do not post admin requests to the list.
