gfapi : Handle the path == "" glfs_resolve_at

2018-08-22T01:05:53+00:00

Currently there is no check for path = "" in glfs_resolve_at.
So if application sends an empty path, then the function resolves
into the parent inode which is incorrect. Plus modified possible
of "path" with "origpath" in the same function.

libgfapi: Fix lookup on root

2018-05-29T14:38:25+00:00

Lookup on root was sending "/" as the path.
This will break the basename calculation in
loc_copy and hence lookup on root was failing
if the loc_copy was involved in the stack.

With ctime, a first lookup on root initiates
a metadata self heal because of ctime xattr
not being same on all afr subvolumes. This
results in loc_copy and hence the failure
of lookup.

Fix would be to send path with "." for the root.

Revert "gfapi: return pre/post attributes from glfs_fsync/fdatasync"

2018-05-08T15:27:48+00:00

This reverts commit 09943beb499617212f2985ca8ea9ecd1ed1b470e.

This is being reverted as the API signatures should adapt to a
statx like structure, and also all APIs that need to return
pre/post attrs are not complete.

As a result, instead of fixing up part of the APIs and then
refixing the same in a later release, removing these set of
fixes from the branch.

gfapi : Resolve "." and ".." only for named lookups

2017-06-20T12:32:20+00:00

The patch https://review.gluster.org/#/c/17177 resolves "." and ".."
to corrosponding inodes and names before sending the request to the
backend server. But this will only work if inode and its parent is
linked properly. Incase of nameless lookup(applications like ganesha)
the inode of parent can be NULL(only gfid is send). So this patch will
resolve "." and ".." only if proper parent is available

gfapi: change root lookup from nameless to named lookup

2017-06-09T11:58:36+00:00

Problem:

During component resolve we do lookup on root based on
root gfid. If we are doing nameless lookup, then md-cache
won't be able to serve those lookup.

Solution:

With this patch, we covert nameless lookup to named lookup
on root.

This patch is to handle "." and ".." in file path. Which means
this special dentry names will be resolved before sending fops
on the path.
