libglusterfsclient: Re-validate root inode on every path resolution

2009-09-24T08:18:46+00:00

If the root inode's is outdated, send a revalidate on it.
A revalidate on root inode also reduces the window in which an
op will fail over distribute because the layout of the root
directory did not  get constructed when we sent the lookup on
root in glusterfs_init. That can happen when not all children of a
distribute volume were up at the time of glusterfs_init.

libglusterfsclient: Move DHT root-lookup workaround to init

2009-07-20T21:29:26+00:00

The workaround for the DHT requirement for a lookup on /
needs to be done only once when the xlator graph is inited.
Doing it on every path's lookup results in a major performance
penalty when using distribute subvolumes upwards of 16, as reported
by Avati.

libglusterfsclient: Simplify inode and stat caching

2009-06-03T07:25:55+00:00

There is a mechanism for caching the inode numbers got from a lookup
and a struct stat got from a stat or fstat but I wasnt sure if it worked.
This commit simplifies cache updates and checks and the accompanying
tests have made sure that the cache does work.

libglusterfsclient: __do_path_resolve: Fix pathname resolution bug

2009-05-18T13:43:12+00:00

In __do_path_resolve, we need to use the new_loc.path as the input
for resolution rather than the resolved variable, simply because we're
not interested in resolving the names that have been resolved, as
pointed out by the variable name 'resolved'. Instead, we need to resolve
new_loc, which stores the next component in the path to
be looked up.

libglusterfsclient: Fix segfault on non-NULL loc->name

2009-04-17T07:48:16+00:00

The gf_log message actually assumes that loc->name will have a valid
non-NULL name in it, whereas if the loc_t being passed to it was
actually created on a function stack, i.e. a local function variable
and was then passed down the code path to do_path_resolve without ever
initing it or zeroing the structure, its possible that the name member
has a non-NULL but corrupted address. This leads to a segfault.
Whereas, we know loc->path will always have the full path.

libglusterfsclient: Remove spurious strcmp

2009-04-08T09:35:38+00:00

This strcmp existed because of assumptions that do
not hold true since the change in libglusterfsclient
internals recently.

This is another step in fixing the seg-fault on glusterfs_create.
Patch adapted from Raghu's original fix to the problem.
