memcache: Properly track the size of talloc objects

2019-04-06T05:12:21+00:00

With memcache_add_talloc, the talloc object becomes part of the pool and
the memcache_element stores a pointer to the talloc object. The
size of the the talloc object was not used when tracking the used space,
allowing the cache to grow larger than defined in the memcache_init
call.

Fix this by adding the size of the talloc object to the used space.

Also record the initial size of the talloc object for proper adjustment
of the used space in the cache later. This is in case the size of the
talloc object is modified while being owned by the cache (e.g.
allocating talloc child objects). This should never happen, but better
be safe than ending up with a broken cache usage counter.

s3: VFS: Change SMB_VFS_GETWD to return struct smb_filename * instead of char *.

2017-07-01T01:07:11+00:00

We need to migrate all pathname based VFS calls to use a struct
to finish modernising the VFS with extra timestamp and flags parameters.

lib/util: Include DEBUG macro in internal header files before samba_util.h

2015-03-11T17:47:22+00:00

It's best practice to include external header files before internal
header files. In this case internal DEBUG macro cannot be defined and
therefore samba version of debug macro will be included
in header file "util/fault.h".

In file included from example.c:27:0:
src/util/util.h:127:0: error: "DEBUG" redefined [-Werror]
 #define DEBUG(level, format, ...) do { \

This is generic enough that it could be used in all code.
