caller doesn't have to worry about the constraint of only opening a
database a single time in a process. These wrappers will ensure that
only a single open is done, and will auto-close when the last instance
is gone.
When you are finished with a database pointer, use talloc_free() to
close it.
note that this code does not take account of the threads process
model, and does not yet take account of symlinks or hard links to tdb
files.

of associated functions.
The motivation for this change was to avoid having to convert to/from
ucs2 strings for so many operations. Doing that was slow, used many
static buffers, and was also incorrect as it didn't cope properly with
unicode codepoints above 65536 (which could not be represented
correctly as smb_ucs2_t chars)
The two core functions that allowed this change are next_codepoint()
and push_codepoint(). These functions allow you to correctly walk a
arbitrary multi-byte string a character at a time without converting
the whole string to ucs2.
While doing this cleanup I also fixed several ucs2 string handling
bugs. See the commit for details.
The following code (which counts the number of occuraces of 'c' in a
string) shows how to use the new interface:
size_t count_chars(const char *s, char c)
{
size_t count = 0;
while (*s) {
size_t size;
codepoint_t c2 = next_codepoint(s, &size);
if (c2 == c) count++;
s += size;
}
return count;
}

which is much clearer and simpler to use. It removes a specific parent
from a pointer, no matter whether that parent is a "reference" or a
direct parent. This gives complete control over the free process.

the % coverage in terms of lines of code of a test suite. I thought a
good first place to start with gcov was the talloc test suite. When I
started the test suite covered about 60% of all lines of code in
talloc.c, and now it covers about 99%. The only lines not covered are
talloc corruption errors, as that would cause smb_panic() to fire.
It will be interesting to try gcov on the main Samba test suite for
smbd. We won't achieve 100% coverage, but it would be nice to get to
90% or more.
I also modified the talloc.c sources to be able to be build standalone, using:
gcc -c -D_STANDALONE_ -Iinlcude lib/talloc.c
that should make it much easier to re-use talloc in other projects

might not place the pointer in the context specified in the docs. The
code was assuming that pointer was at the head of the child list,
which it may not be, depending on what other operations have happened
in between.

The problem was that the simple "uint_t ref_count;" in a talloc chunk
did not give enough information. It told us that a pointer was
referenced more than once, but it didn't say who it was referenced
by. This means that when the pointer was freed we had no sane way to
clean up the reference.
I have now replaced ref_count with a "refs" list, which means that
references point to the pointer, and the pointer has a linked list of
references. So now we can cleanup from either direction without losing track of anything.
I've also added a LOCAL-TALLOC smbtorture test that tests talloc
behaviour for some common uses.

circular references (circular references are allowed, they just need
to be handled carefully inside talloc)

void *talloc_reference(const void *context, const void *ptr);
this function makes a secondary reference to ptr, and hangs it off the
given context. This greatly simplifies some of the current reference
counting code in the samr server and I suspect it will be widely used
in other places too.
the way you use it is like this:
domain_state->connect_state = talloc_reference(domain_state, connect_state);
that makes the element connect_state of domain_state a secondary
reference to connect_state. The connect_state structure will then only
be freed when both domain_state and the original connect_state go
away, allowing you to free them independently and in any order.
you could do this alrady using a talloc destructor, and that is what
the samr server did previously, but that meant this construct was
being reinvented in several places. So this convenience function sets
up the destructor for you, giving a much more convenient and less
error prone API.

a const pointer really means that "the data pointed to by this pointer
won't change", and that is certainly true of talloc(). The fact that
some behind-the-scenes meta-data can change doesn't matter from the
point of view of const.
this fixes a number of const warnings caused by const data structures
being passed as talloc contexts. That will no longer generate a
warning.
also changed the talloc leak reporting option from --leak-check to
--leak-report, as all it does is generate a report on exit. A new
--leak-report-full option has been added that shows the complete tree
of memory allocations, which is is quite useful in tracking things down.
NOTE: I find it quite useful to insert talloc_report_full(ptr, stderr)
calls at strategic points in the code while debugging memory
allocation problems, particularly before freeing a major context (such
as the connection context). This allows you to see if that context has
been accumulating too much data, such as per-request data, which
should have been freed when the request finished.

- fixed a couple of memory leaks found with the new tricks
A typical exit report for smbd is now:
talloc report on 'null_context' (total 811 bytes in 54 blocks)
auth/auth_sam.c:334 contains 20 bytes in 1 blocks
struct auth_serversupplied_info contains 498 bytes in 33 blocks
UNNAMED contains 8 bytes in 1 blocks
lib/data_blob.c:40 contains 16 bytes in 1 blocks
iconv(CP850,UTF8) contains 61 bytes in 4 blocks
iconv(UTF8,CP850) contains 61 bytes in 4 blocks
iconv(UTF8,UTF-16LE) contains 67 bytes in 4 blocks
iconv(UTF-16LE,UTF8) contains 67 bytes in 4 blocks
UNNAMED contains 13 bytes in 1 blocks
