Hi Omniorb developers,
I would need a little explanation about object refs management with =
anys.
Up to 2.6.1 the manual stated that any values did not manage refs; =
indeed the refcount did not change across insertion/extraction. This =
created some troubles in cases when ownership of refs could not be =
transferred to any. I wrote a small portable package to fully serialize =
anys through dynany recursive scan (and the contrary); when loading from =
a stream to an any, there was need to keep track of all refs created =
through object_to_string() so that they could be released upon context =
deletion (e.g. StreamToAny object disposal).
Now, if I correctly understand 2.8 semantics, anys do a _duplicate() =
when they are fed with refs, and all extractors should do the same (so =
this would make the above problem much simpler because I can _release() =
the ref after the any has taken it, and the ref is then disposed when =
the any is destroyed unless someone _duplicate() the ref).
Is that correct ? Thanks,
Renzo Tomaselli =20
