But I have noticed a new bug, very strange: The records stored in cache

I really do not understand, I printed all records on screen, when they
are stored they keep the right sr_name. When I need to get a record
from
cache, sometimes the sr_name is totally crazy!
(Not all records are bad stored only some of them, and always the
same...) . Therefore the record in cache is not found, whether it is in
cache!
What kind of records are bad? Do they have status of 0?

I found where the problem came from:
With my multi thread version, I create a new resolver for each
request. When the request is done, I destroy the resolver, with the
sres_resolver_destroy.
I think that it removes the cache associated with the resolver (with
the destructor() function), that is why the cache memory is freed.
I need to change the sres_resolver_destructor() function (remove the
line sres_cache_unref(res->res_cache));
Thank you,
T.Rosenblatt.
Well I have followed my investigation, and I have found exactly where is
the problem. I don't know why, but there it is.
Here is the stack when I'm destroying a resolver:
#0 _su_home_deinit (home=0x8094eb0) at su_alloc.c:868
#1 0x080541a6 in _su_home_deinit (home=0x8094cb8) at su_alloc.c:860
#2 0x08054853 in su_home_unref (home=0x8094cb8) at su_alloc.c:589
#3 0x0805b64c in sres_resolver_unref (res=0x8094cb8) at sres.c:410
#4 0x08061d79 in sres_resolver_destroy (res=0x8094cb8) at sresolv.c:205
When I remove this line /"free(b->sub_nodes[i].sua_data);"/
in _su_home_deinit, I have no more cache problems.
It's weird, because, this function is sensed to work on a home object
that is totally different from the home object of the cache!!!
Have you got any idea ?
Thank you,
Thomas.
