Re: Is xnu kernel source available for MacOS ( 10.12 beta )

launchd underwent a rewrite for OS X 10.10, and was made a part of libxpc. I can't speak for Apple, but it sure would be nice if some more projects (especially ones like launchd which used to be open source) were re-open-sourced! > On 22 Aug 2016, at 6:57 pm, Quinn The Eskimo! <eskimo1(a)apple.com> wrote: > > >> On 22 Aug 2016, at 17:52, brunomaximom(a)openmailbox.org wrote: >> >> Any idea if launchd will be re-opened or if Apple intends to open source more OS X components in 10.12 release? > > I can’t comment on either of these questions; I /use/ Darwin source, much like you guys, but I’m not involved in the decision making process. > > Share and Enjoy > -- > Quinn "The Eskimo!" <http://www.apple.com/developer/> > Apple Developer Relations, Developer Technical Support, Core OS/Hardware _______________________________________________ Do not post admin requests to the list.

Still wanting to know if anyone was successful using Fusion 8 and OS X 10.11 for kernel debug setup !

Also it is the same problem with 10.12 beta. Tried to post on vmware forum — No response. TIA, Prokash _______________________________________________ Do not post admin requests to the list.

Is there a replacement for PMSessionPrintDialog ?
by Gordo Cath 13 Aug '16

13 Aug '16

Hi, I'm on 10.10.5 64 bit and wondering if HIToolBox has a replacement for PMSessionPrintDialog. I noticed it is deprecated but still available if I build using i386. So its not really deprecated. However I want to run as a 64 bit app. In the deprecation notes I don't see any sort of replacement function , but maybe I'm not looking in the right spot. What or where should I be looking?

Re: calling __pthread_set_self from a remote_thread

_pthread_set_self() is not API (hence the underscore prefix), nor is __pthread_set_self(). What documentation are you referring to? Calling either is not supported.

In the limited documentation I've found, it appears I need to call this function before I can call the dlopen / dlsym calls. Infact if i don't i get a different pthread error which i suspect is for failing to do the first api call. However i digress from the main issue.

calling __pthread_set_self from a remote_thread
by Gordo Cath 04 Aug '16

04 Aug '16

Hi, I find when I call __pthread_set_self from a remote thread in a 64 bit app on osX 10.10 it keeps faulting with an error in pthread_mutex_lock at the time of the crash (using lldb). In the limited documentation I've found, it appears I need to call this function before I can call the dlopen / dlsym calls. Infact if i don't i get a different pthread error which i suspect is for failing to do the first api call. However i digress from the main issue. My guess is that its failing because some other thread has this api locked or some resource locked that the api requires in its use. Also when I was looking around I saw there are two symbols: __pthread_set_self and ___pthread_set_self (one has 2 leading _ and the other has 3 leading _). What are the differences between the two functions? I've generally been using the one with 2 leading _, but have tried both and both fail with the same error. Is it good practice to follow the man page of pthread_mutex_lock and acquire a lock first, then call pthread_set_self? and then after that is finished, then release the lock?
