Add .file_write method in meta_ops and make write support into
virtual files (like loglevel, measure_latency) much simpler.

meta: (re-)Implement Meta translator

2014-05-06T00:28:55+00:00

The meta translator exposes details about glusterfs itself
in the form of a virtual namespace.

Loading the translator on the client side creates the
meta virtual view under $mntpoint/.meta by default. The
directory is not listed (even with ls -a) and can be
accessed by doing a "cd /mnt/.meta"

build: split CPPFLAGS from CFLAGS

2012-10-03T19:26:45+00:00

Automake provides a separate variable for preprocessor flags
(*_CPPFLAGS). They are already uses in a few places, so make it
consistent and use it everywhere. Note that cflags obtained from
pkg-config often are cppflags, which is why LIBXML2_CFLAGS moves with
into AM_CPPFLAGS, for example.

build: remove useless explicit -fPIC -shared from

2012-10-03T19:24:59+00:00

 CFLAGS

libtool will automatically add "-fPIC" to the compiler command line as
needed, so there is no need to specify it separately.

"-shared" is normally a linker flag and has an odd effect when used with
libtool --mode=compile, namely that it inhibits production of static
objects. For that however, using AC_DISABLE_STATIC is a lot simpler.

build: remove -nostartfiles flag

2012-10-02T20:11:43+00:00

The "-nostartfiles" is a discouraged option and is documented to
potentially result in undesired behavior. Since I see no reason why it
should be in glusterfs, remove it.

build: consolidate common compilation flags into one variable

2012-10-01T23:44:50+00:00

Some -D flags are present in all files, so collect them.
This adds -D${GF_HOST_OS} to some compiler command lines,
but this should not be a problem.
