Will OS X 10.7 be also conform to UNIX 03 ? Or is it not that important for Apple ?

Haha- you are petting Schrödinger's cat. activitymonitord is the privileged executable Activity Monitor triggers to scrape all the data it needs to present in the Cocoa UI. When you close Activity Monitor, it dies. Now you see it: > ps aux|grep activitymonitord root 9631 1.6 0.0 2446604 1448 ??

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com This isn't a Darwin-level question. It's a daemon that performs system analysis on behalf of the Activity Monitor.app GUI application. If you don't want it to take CPU, don't run Activity Monitor. top(1) uses a similar percentage of CPU.

Are there pitfalls and limitations in process launching that I ought to know about? Yes, there are limitations on forking; see 'man fork'. You need to wait on your child processes to have their state cleaned up within the kernel. Failing to do so will prevent you from forking new processes. My checks for terminated processes were not complete, and, in particular, my manual process termination wasn't safe. I used kill() with SIGTERM, and if that failed, SIGKILL, but if that failed I just ignored it. After testing this thoroughly, I have found that SIGKILL often fails, which then leaves that process in an unknown state, possibly blocking pty's. I am not sure if that is an expected behavior. My current solution is to try SIGKILL over and over, up to 1000 times, until it works. I find that it usually works after one or two tries, but sometimes I see as much as ten tries. I have tested for a whikle and it hasn't failed me so far. But is this violent bashing against a process until it dies, is this really the way to do it?

Re: dyld changes on lion
by Nick Blievers 08 Aug '11

08 Aug '11

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com As pointed out, the source is your best bet. But the short answer is that the dyld image can now be loaded at a (not very) random address. Try running your binaries from within gdb (ie not attaching to them after they have started, but actually starting from within gdb). This will disable the sliding and at least confirm if this is the issue or not. Hope this helps, Nick On 07/08/2011, at 12:51 AM, Joel Reymont wrote: > I have some hand-generated binaries that started crashing on Lion in dyld. > > What are the changes in dyld from Snow Leopard to Lion? > > Where can I read up on these changes? > > Thanks, Joel > > -------------------------------------------------------------------------- > - for hire: mac osx device driver ninja, kernel extensions and usb drivers > ---------------------+------------+--------------------------------------- > http://wagerlabs.com | @wagerlabs | http://www.linkedin.com/in/joelreymont > ---------------------+------------+--------------------------------------- > > > > _______________________________________________ > Do not post admin requests to the list.

software RAID status checking
by Julian Mayer 07 Aug '11

07 Aug '11

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com hello all i've got a few questions regarding checking the status of a software RAID. • which are the proper APIs to check the status of all attached software RAIDs, i.e. perform the equivalent of "diskutil appleRAID list". google search or grepping /System/Library/Frameworks/ turned up nothing on this matter. • if there is no public API to check the software RAID status, has anyone more information on the specific output of "diskutil appleRAID list". more specifically i've seen "Online" and "Offline" as possible results of the "Status:" field, are there any more like "Degraded"? are there possible results for device node status besides "Online" and "Missing/Damaged"? did the output change in recent versions of Mac OS X? are the possible status values different for "Stripe" and "Mirror" RAIDs? • does anyone know of a way to simulate RAID degradation? just un-plugging a drive? this only leads to the RAID being offline, is this the same as degradation? • is the source to "diskutil" by chance buried somewhere here http://www.opensource.apple.com/ ? thanks, julian _______________________________________________ Do not post admin requests to the list.
