This is a fun one -- I don't know if anyone has the answer, but
hopefully someone here has better knowledge of how Apple is handling
I'm loading executable code from a bundle, and in 10.4 it loaded
"cleanly"; i.e. each instance seemingly had a unique data space
context associated with it.
What I am doing is getting the bundle via CFBundleCreate(), then I
load the executable code with CFBundleLoadExecutable() (I do an
unload if the bundle had been loaded previously). But it seems that
subsequent loads of the code are pointing to the same Bundle ref in
The Apple docs say this about CFBundleCreate():
"Once a bundle has been created, it is cached; the bundle cache is
flushed only periodically. CFBundleCreate does not check that a cached
bundle still exists in the filesystem. If a bundle is deleted from the
filesystem, it is therefore possible for CFBundleCreate to return a
cached bundle that has actually been deleted."
and I suspect this may be causing the problem. The docs also say this
"May return an existing CFBundle object with the reference count
Does anyone know if there is a way to flush the cache or zero the
reference count on CFBundle objects?
