cluster/distribute: send getxattr on LOCKINFO to only cached subvolumes.

2012-11-28T06:43:57+00:00

lk is sent to only cached subvolume. Hence there is no point in
sending LOCKINFO to other children (even in case of directories).

cluster/dht: dump the layout information of directories only

2012-11-19T10:58:06+00:00

testcase:
The changes are for removing gf_log from statedump related sections in dht and
using pthread_mutex_trylock in statedump sections. Changes are internal. So
tests were done by attaching gdb to the process and executing by manually
changing the values of some of the pointers.

cluster/dht: ignore empty ->hashed_subvol during lookup

2012-10-17T07:16:05+00:00

->hashed_subvol is not valid (== NULL) when the subvolume
the entity hashes to is down. For directories, we need not
rely on ->hashed_subvol as we aggregate information from all
subvolumes. So, during lookup, NULL ->hashed_subvol is ingored
but logged.

cluster/distribute: Always return the latest time in struct iatt.

2012-10-16T21:27:15+00:00

save the a/c/mtime in inode_ctx, and dht_inode_ctx_update
checks the passed iatte, and updates the stat's time,
and inode_ctx's time accordingly. For preparent times, only
the iatt stat to be returned is updated, not the ctx.

With this, update, WIPE is removed, as we would always be passing
back the latest mtime, and hence cache times will be relevant.

TODO-handle rename WIPE calls

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.
