Avoid conflict between contrib/uuid and system uuid

2015-04-04T17:48:35+00:00

glusterfs relies on Linux uuid implementation, which
API is incompatible with most other systems's uuid. As
a result, libglusterfs has to embed contrib/uuid,
which is the Linux implementation, on non Linux systems.
This implementation is incompatible with systtem's
built in, but the symbols have the same names.

Usually this is not a problem because when we link
with -lglusterfs, libc's symbols are trumped. However
there is a problem when a program not linked with
-lglusterfs will dlopen() glusterfs component. In
such a case, libc's uuid implementation is already
loaded in the calling program, and it will be used
instead of libglusterfs's implementation, causing
crashes.

A possible workaround is to use pre-load libglusterfs
in the calling program (using LD_PRELOAD on NetBSD for
instance), but such a mechanism is not portable, nor
is it flexible. A much better approach is to rename
libglusterfs's uuid_* functions to gf_uuid_* to avoid
any possible conflict. This is what this change attempts.

CID: 1128907
The pointer variable 'bdatt' redirected to a goto label
when the value was NULL and in the other condition when it is not NULL
, hence the bdatt is again checked for NULL at 'reverse xattr' label.

core: fix remaining *printf formation warnings on 32-bit

2014-11-26T08:26:53+00:00

This fixes a few lingering size_t problems. Of particular note are
some uses of off_t for size params in function calls.

There is no correct, _portable_ way to correctly print an off_t. The
best you can do is use a scratch int64_t/PRId64 or uint64_t/PRIu64.
