tdb. This includes:
- the new tdb_lockall and tdb_lockall_read code, which will be needed
for the ldb speedups
- the tdb logging changes. This is an intermediate step to keep the
differences between the two branches small. The plan is still to
move to a tdb_init()/tdb_set_logging_function()/tdb_attach() style
of open which will make things much cleaner.
- the updated test suites and standalone tdb build code
- use libreplace headers
There are still some small differences I haven't merged. I'll discuss
those on the list.

definitions which
are not compatible. I am aware that this would be a huge change in Samba4, but
I would like to see it in the code that is shared.
Stefan, when you do merge work, can you get this across to Samba4?
Thanks,

On Linux,
F_RDLCK is defined to 0, for example NetBSD has it at 1.
Still does not work fully though. Still investigating.
This might also be interesting to Samba4.

has the linear posix locking issue which causes
CLEAR_IF_FIRST to cause performance problems.
As we know we're in a daemon architecture with
long-lived parent we can avoid this in the Samba
case. Add a comment explaining this.

realloc can return NULL in one of two cases - (1) the realloc failed,
(2) realloc succeeded but the new size requested was zero, in which
case this is identical to a free() call.
The error paths dealing with these two cases should be different,
but mostly weren't. Secondly the standard idiom for dealing with
realloc when you know the new size is non-zero is the following :
tmp = realloc(p, size);
if (!tmp) {
SAFE_FREE(p);
return error;
} else {
p = tmp;
}
However, there were *many* *many* places in Samba where we were
using the old (broken) idiom of :
p = realloc(p, size)
if (!p) {
return error;
}
which will leak the memory pointed to by p on realloc fail.
This commit (hopefully) fixes all these cases by moving to
a standard idiom of :
p = SMB_REALLOC(p, size)
if (!p) {
return error;
}
Where if the realloc returns null due to the realloc failing
or size == 0 we *guarentee* that the storage pointed to by p
has been freed. This allows me to remove a lot of code that
was dealing with the standard (more verbose) method that required
a tmp pointer. This is almost always what you want. When a
realloc fails you never usually want the old memory, you
want to free it and get into your error processing asap.
For the 11 remaining cases where we really do need to keep the
old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR,
which can be used as follows :
tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size);
if (!tmp) {
SAFE_FREE(p);
return error;
} else {
p = tmp;
}
SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the
pointer p, even on size == 0 or realloc fail. All this is
done by a hidden extra argument to Realloc(), BOOL free_old_on_error
which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR
macros (and their array counterparts).
It remains to be seen what this will do to our Coverity bug count :-).

1. using smbc_getxattr() et al, one may now request all access control
entities in the ACL without getting all other NT attributes.
2. added the ability to exclude specified attributes from the result set
provided by smbc_getxattr() et al, when requesting all attributes,
all NT attributes, or all DOS attributes.
3. eliminated all compiler warnings, including when --enable-developer
compiler flags are in use. removed -Wcast-qual flag from list, as that
is specifically to force warnings in the case of casting away qualifiers.
Note: In the process of eliminating compiler warnings, a few nasties were
discovered. In the file libads/sasl.c, PRIVATE kerberos interfaces
are being used; and in libsmb/clikrb5.c, both PRIAVE and DEPRECATED
kerberos interfaces are being used. Someone who knows kerberos
should look at these and determine if there is an alternate method
of accomplishing the task.

"qualifiers". The
whole of samba comiles warning-free with the default compiler flags.
Temporarily defined -Wall to locate other potential problems. Found an
unused static function (#ifdefed out rather than deleted, in case it's
needed for something in progress).
There are also a number of uses of undeclared functions, mostly krb5_*.
Files with these problems need to have appropriate header files included,
but they are not fixed in this update.
oplock_linux.c.c has undefined functions capget() and capset(), which need
to have "#undef _POSIX_SOURCE" specified before including <sys/capability.h>,
but that could potentially have other side effects, so that remains uncorrected
as well.
The flag -Wall should be added permanently to CFLAGS, and all warnings then
generated should be eliminated.
