file_compare() returns true if two files are the same. It is meant for
small files.

these are very useful for writing files with formatted writes

This changes the meaning of the ->prev pointer in our doubly linked
lists to point at the end of the list from the front of the list. That
allows us to implement DLIST_ADD_END() and related functions in O(1)
time, which can be a huge saving in many places in Samba.
This also means that the 'type' argument to various DLIST_*() macros
is no longer needed, but I have left it in for now to keep the
patchset small, which will make it easier to revert if any problems
are found. In the future we should remove the 'type' arguments.
(jra. Move the one use of DLIST_TAIL over to the new macros).

uses of (list)->prev are moved over to DLIST_PREV. This will be replaced
when the final (new) version of the dlinklist.h header is added.

If a process (or the machine) dies after just after writing the
recovery head (pointing at the end of file), the recovery record will filled
with 0x42. This will not invoke a recovery on open, since rec.magic
!= TDB_RECOVERY_MAGIC.
Unfortunately, the first transaction commit will happily reuse that
area: tdb_recovery_allocate() doesn't check the magic. The recovery
record has length 0x42424242, and it writes that back into the
now-valid-looking transaction header) for the next comer (which
happens to be tdb_wipe_all in my tests).

This should make it easier to keep all release scripts alined as it will reduce
the difference between them to ideally a few variables
Also moves the tdb script in the scripts directory.

|
We must perform abi checks against the version we are going to release.
Not against the current tree we are in.
|
|
teach the abi check scripts to skip the DOXYGEN sections
fix the header to use #ifdef DOXYGEN and not #if DOXYGEN

after recent fixes we need to raise the version to 1.2.1 so that
we can require also the right patched version.

On my older CentOS 4 installation I had the problem with the missing
substitution prototypes ("uwrap_*"). So I added them to "uid_wrapper.h".
Also, I made the head of the "uid_wrapper.c" file more like the one of
"nss_wrapper.c" - it shouldn't change that much, I did it only to be consistent.
This patch should fix the build on older distributions while keep it running on
newer ones.

The includes of the UID wrapper headers werent't really efficient according
to metze's post on the technical mailing list (http://lists.samba.org/archive/samba-technical/2010-February/069165.html).
To achieve this move the "uid_wrapper.h" includes into "lib/util/unix_privs.c",
"lib/util/util.c", "ntvfs/posix/pvfs_acl.c" and "ntvfs/unixuid/vfs_unixuid.c".

There was a bug in tdb where the
tdb_brlock(tdb, GLOBAL_LOCK, F_UNLCK, F_SETLKW, 0, 1);
(ending the transaction-"mutex") was done before the
/* remove the recovery marker */
This means that when a transaction is committed there is a window where another
opener of the file sees the transaction marker while the transaction committer
is still fully functional and working on it. This led to transaction being
rolled back by that second opener of the file while transaction_commit() gave
no error to the caller.
This patch moves the F_UNLCK to after the recovery marker was removed, closing
this window.

We want to avoid the usage of talloc_reference() in Samba.

There was only one user, which isn't worth it for the overhead.

added rep_memmem() and a testsuite
|
|
This makes sure we fill the unspefic bytes with 0
and have zero termination for sockaddr_un.
