uss/svc: Send the first lookup to the normal graph

2017-08-14T07:30:20+00:00

When parent inode is not looked up before, the inode type
won't be set. In this scenario we should send the lookup
to the normal graph first.

svc: send revalidate lookup on special dir

2017-07-09T04:57:48+00:00

.snaps directory is a virtual direcotory, that doesn't
exist on the backend. Even though it is a special dentry,
it doesn't have a dedicated inode. So the inode number is
always random. Which means it will get different inode
number when reboot happens on snapd process.

Now with windows client the show-direcotry feature requires
a lookup on the .snpas direcoty post readdirp on root.
If the snapd restarted after a lookup, then subsequent lookup
will fail, because linked inode will be stale.

This patch will do a revalidate lookup with a new inode.

In case dict_set_dynstr_with_alloc fails, dict_unref is done
when exection jumps to label 'out'.

snapshot: svc_stat collides with define from /usr/include/rpc/svc.h

2016-04-27T09:11:56+00:00

Compiling fails with this error:

    snapview-client.c:559:24: error: macro "svc_stat" passed 4 arguments, but takes just 1
               dict_t *xdata)

svc_* is the common prefix for (SUN)RPC functions provided by system
headers. svc_stat() seems to be an existing function name. This happens
because change-id I98fc8cf7e4b631082c7b203b5a0a77111bec1fb9 causes
 included through "glusterfs.h". Prepending gf_ for all svc_*
functions works around the symbol collision.

gluster/uss: change ctime attr of a dir when USS enabled

2016-03-10T10:44:27+00:00

Consider a testcase:
 mount -t nfs host1:/vol1 /mnt
 ls /mnt
 ls /mnt/.snaps (As expected this fails)
 gluster volume set vol1 features.uss enable

Now `ls /mnt/.snaps` should work, but fails with No such file or
directory.
This is because NFS client  and Kernel VFS caches the list of files in a
directory.
This cache is updated if there are any changes in the directory attributes.

This patch solves the problem by changing ctime attribute when USS is
enabled
