a bug report made me start investigating:
http://bugzilla.opengroupware.org/bugzilla/show_bug.cgi?id=2025
in revision: 27630 NSZoneMallocAtomic disappeared from NSZone.h, due to: "GC
changes for MacOS-X compatiblity", since the svn log entry.
NSZoneMallocAtomic was added:
Fri May 21 16:40:00 1999 Richard Frith-Macdonald <rich...@xxxxxxxxxxxxxxxx>
* Source/include/NSZone.h: Added NSZoneMallocAtomic() for Helge
and in anticipation of adding garbage collection support some day.
the only usage of it that I found also was removed at the same revision 27630
in Source/NSNotificationCenter.m:
= (Observation*)NSZoneMallocAtomic(NSDefaultMallocZone(), size);
= (Observation*)NSZoneMalloc(GSAtomicMallocZone(), size);
NSZoneMallocAtomic is implemented this way in NSZone.h in stable 0.18:
/**
* Allocates mmemory of size bytes from zone, with the assumption that the
* memory will never contain pointers. This is only relevant in situations
* where a form of garbage collection is enabled, and NSZoneMalloc() should
* always be used otherwise. Not defined by OpenStep or OS X.
*/
GS_ZONE_SCOPE void* NSZoneMallocAtomic (NSZone *zone, size_t size)
{
return NSZoneMalloc(GSAtomicMallocZone(), size);
}
sope doesn't compile anymore with gnustep-base trunk. When I take a look at
the code in sope, how it is using NSZoneMallocAtomic there I see, it is using
NSZoneMallocAtomic everywhere but for NeXT_Foundation_LIBRARY I guess, it may
also be available on Mac OS X, but I've no possibility to check that out, at
least googling NSZoneMallocAtomic only finds references to gnustep and
libFoundation.
I'm writing here, because of my research now, I'm not perfectly sure whether
it was removed intentionally or accidently.
cheers
Sebastian
